Title: Improvements in or relating to frames, particularly for windows
IPC: E06B3/968
Filed: 1981-05-01
Abstract: In an extruded aluminium window frame there is provided a resilient C-shaped bracing element 23 extending across each mitred junction 22 between two adjacent frame members 10, 11, the element 23 being secured to each frame member at least in part by virtue of its resilient engagement therewith. The resilient engagement between the bracing element 23 and the frame members is such as to apply to said members forces in a sense to tend to close the mitred junction 23 between the members, so that not only does the bracing element provide a reinforcement to preventing opening of the mitred junction but it also exerts a positive force to maintain the junction closed. <IMAGE>

Abstract: An apparatus (10) is proposed with which a closed circuit (13) for a braking function is supplied with a priority constant flow and an open circuit (16) for an additional load (18) is supplied with the residual flow or a total flow. A control valve (21) switching the flow from the pump (12) is coupled to a stepped piston (47) and influences a flow of control oil branched from the pump flow and which can be conveyed to the tank (69) through a throttle (32) and a pilot valve (23) controlled by the pressure in the accumulator (14) wherein the pressure drop across the throttle (32) can be effective at the stepped piston (47) to move the piston (47) and attached control valve to the switched position. The pilot controlled control valve (21) switches accurately and always moves into stable end positions in which it operates in addition as a flow regulator. A modified valve arrangement is described with respect to Fig. 2 (not shown). <IMAGE>

Title: Control of machine tool for non-circular machining
IPC: B23Q15/013
Filed: 1981-05-18
Abstract: A stack 6 of piston rings to be machined to a non-circular contour is rotated by a work spindle 5 and machined by a tool 12 whose radial movement is controlled by a d.c. servomotor 29. Memory 22 holds a number of different non-circular contours which can be selected by switch 24. The stored contours are referred to a standard diameter and are corrected by microprocessor 26 in accordance with the required diameter set on decode switch 27. An angle pick-up 34 co-ordinates the angular position of the work- piece and the stored contour and allows a phase difference to compensate for delay in the control system. A probe 36 measures the actual contour produced so that corrections can be made in the stored contour. <IMAGE>

Title: Cleaning Automatic Film Developing Apparatus
IPC: G03D3/13
Filed: 1981-06-10
Abstract: A method for cleaning rollers or other film-conveying members in a treatment bath of an automatic film developing apparatus.

Title: Automatic headlight dipping control
Inventor: CUNNINGHAM DEREK
IPC: B60Q1/14
Filed: 1981-06-23
Abstract: An automatic headlight control device comprises a photocell for detecting the lights of an approaching vehicle provided with a shield for preventing illumination by stray sources, and a multiposition switch for causing in one position thereof a headlight to be dipped when the photocell is illuminated. The shield means may be of hollow frustoconical construction with light entering at its narrow end and the photocell being located at its broad end. If a slot is provided extending from end to end, the shield can be so positioned that the photoelectric means will continue to register the presence of an approaching vehicle until that vehicle is level. If the slot is shorter or not present at all, the photocell will cease to register the presence of an approaching vehicle a short time before that vehicle is level. An adjustable shutter may be provided for changing the length of the slot. Both headlights may be controlled by a single photocell secured on the offside. Other positions of the switch means permit manual override. <IMAGE>

Title: Elastomeric spring stressed by liquid
Inventor: RANDELL WILLIAM FRANCIS
IPC: F16F9/32
Filed: 1984-06-05
Abstract: A spring comprises a hollow body 1 having an opening in which 1 is mounted an elastomeric bush (2) bush (2) through which a plunger 3 may slide. The body, bush and plunger define a cavity 4 in which there is located support means 6 for providing non-rigid support for the plunger 3 in a sideways direction perpendicular to longitudinal axis of the spring whilst permitting longitudinal movement of the plunger relative to the body. The support means 6 is an elastomeric bush. The cavity 4 is filled with incompressible fluid and when in use the spring is subject to compression loads the resulting movement of the plunger into the cavity increases the pressure of the fluid which flows through or around the support means 6 and deforms the bush 2, thus providing the spring force. Further movement of the pluner ceases when the force acting on the end of the plunger due to the fluid pressure equals the externally applied compression load. In Fig. 3, the support means for the plunger 22 is a plate loosely carried by the plunger head. This allows a limited sideways movement of the plunger. <IMAGE>

Title: Zinc plating bath; preventing whisker formation
Inventor: CHRISTIE IAN ROBERT ARTHUR
IPC: C25D3/24
Filed: 1984-07-27
Abstract: A zinc electroplating solution comprises an organic brightener and an additive capable of co- depositing a small proportion of another metal (eg Co, Ni or Cu) with the zinc during electroplating, wherein the other metal is capable of relieving localised internal stress in the electro-deposited zinc. Because the co-deposited metal relieves stress in the zinc, the growth of zinc whiskers, which can occur over a period of months and result in short circuits in zinc plated electronic components, is prevented.
