Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

"MECANISMO DE ESTERçAMENTO". Mecanismo de esterçamento de pinhão (4) e cremalheira (1) para um veículo no qual a razão do ângulo de esterçamento varia em função pelo menos do ângulo de volante provido pelo condutor e da velocidade do veículo. O mecanismo de esterçamento compreende uma cremalheira (1) deslocável lateralmente com respeito ao alojamento do mecanismo de esterçamento e um pinhão (4) lateralmente móvel dentro do alojamento substancialmente na direção do deslocamento da cremalheira (1) enquanto engatado com a cremalheira (1) A razão de ângulo de esterçamento é aumentada na região central do curso da cremalheira (1) em comparação com as regiões laterais da mesma, e a razão de ângulo de esterçamento é adicionalmente aumentada na região central quando o veículo estiver em alta velocidade.

5Planing or slotting machines cutting otherwise than by relative movement of the tool and workpiece in a straight line
 Appl.No 97918839 Applicant BISHOP STEERING PTY LTD Inventor SCOTT DAVID WILLIAM
This invention relates to a method for manufacturing a plurality of longitudinally extending slots in the bore of a component (1). One example of such a component is the sleeve element of an automotive power steering rotary valve. More particularly the invention is directed towards a method of minimising burring of the slot edges of the sleeve component. The method comprises the steps of gripping the component in a gripping means (2) of a workholding device, performing a cutting operation (5) in which the slot is cut in the bore by a cutting tool (5), and further machining the edges of the slot by inserting a deburring means (30) into the bore and imparting relative angular reciprocation between the deburring means and the component.

 Appl.No 09101181 Applicant Bishop Steering Pty Limited Inventor Scott, David William

Apparatuses and methods are implemented for machining a longitudinally extending slot in a bore of a component. The component is gripped in a gripping device of a workholding device. A cutting operation is performed in order to cut the slot in the bore by a cutting tool. The cutting operation forms burred slot edges. The edges are further machined by inserting a deburring device into the bore. Relative angular reciprocation for a limited angle is imparted between the deburring device and the component.

 Appl.No 87660/91 Applicant Bishop Steering Technology Limited Inventor Bishop, Arthur Ernest
A machine for grinding the metering edge contours on edges of axially extending grooves (46) of a power steering valve input-shaft (7) by means of a cylindrical grinding wheel (1) the machine being constructed to hold and rotate the input-shaft (7) and to increase and decrease cyclically the distance between the axis of the input-shaft (7) and the grinding wheel (1) several times during the revolution of the input-shaft (7) to grind metering edge contours to produce symmetrical sets of clockwise and anticlockwise metering edge contours, the input-shaft being centrelessly supported by means of surfaces (8, 8a, 9, 9a) tangentially contacting the outside diameter of the input-shaft, two such surfaces (8, 8a) being axially displaced on either side of the ends of the grooves in the input-shaft and being arranged one on each side of the grinding wheel on that side of the input-shaft (7) adjacent the grinding wheel (1) and other of the support surfaces (9, 9a) being arranged substantially at right angles to the first two support surfaces (8, 8a) to constrain the input-shaft against motion in a direction parallel to the first two support surfaces (8, 8a), a pair of pressing members (10, 11) contacting the outside diameter of the input-shaft (7) one each displayed axially either side of the ends of the grooves (46) and loaded so as to press the input-shaft (7) in a direction generally towards the first two support surfaces (8, 8a).

 Appl.No 16745/92 Applicant Bishop Steering Technology Limited Inventor Baxter, John
A hydraulic power steering rotary valve of generally conventional construction characterised in that the on-centre characteristics of the valve are governed by an arrangement of rolling elements (22) and pairs of notched elements (10, 20) arranged to produce a detent action between the input shaft (1) and the sleeve or driven member (2), one notched element (2) of each pair being fixed to a carrier (11) which is connected to the sleeve or driven member (2) by securing means (13) that, during assembly, is free to move under the influence of springs (23) acting on the notched elements (20) and thereby take up a position such that after completion of assembly the notched elements (10, 20) and rolling elements (22) are precisely in the correct position to provide the required detent action.

A rack (1) and pinion (4) steering gear for a vehicle in which the steering angle ratio varies as a function of at least both the steering wheel angle input by the driver and vehicle speed. The steering gear comprising a rack (1) laterally displaceable with respect to a steering gear housing and a pinion (4) laterally moveable within the housing substantially in a direction of travel of the rack (1) whilst engaged with the rack (1). The steering angle ratio is increased in a central region of travel of the rack (1) when compared to regions either side thereof, and steering angle ratio is further increased in the central region as vehicle speed increases.
