Title: Chairs for the support of enfeebled persons
IPC: A61G5/00
Filed: 1972-10-24
Abstract: 1372552 Adjustable seats for incontinent &c. patients A F ANFILOGOFF and I R MADGE 24 Oct 1972 [24 July 1971] 34860/71 Headings A4J and A4N [Also in Division B7] A wheel chair comprises a unitary shell 11, incorporating a seat 13 and back 14, which is pivotally supported on a frame for adjustment about a transverse axis, the shell back 14 being transversely and vertically curved to give an enfeebled occupant support and the lateral extremities of the upper and lower edges of the back being substantially equidistantly spaced from a vertical median plane of the chair. The shell is moulded glass reinforced plastics and has integral wings 16 and arms 15. The shell is mounted on the frame by an axle 18 which engages in one of a series of holes 25 in each of the front frame uprights. Frame longitudinals 24 carry notched racks 26 in which struts 29, pivotally mounted to the shell at 30 engage to determine the angular position of the shell. The frame wheels 40 may be adjustable in height. A loose or press studded seat cushion 31 and a back cushion 34, which is fitted to a glass reinforced plastics shell 38 that clips into the shell 11, are provided. The cushions are waterproof and define with the lower rear part of shell 11, a urine channel 36 which has a drain hole 43. A urine collection bag may be attached to hooks 44 on the shell 11. In another embodiment, Fig.4, axle 18 is engaged in slots 47 at either side of a plastics base 50 which is provided with castors 48 and brakes 49. A bar 45 protruding at either side of the shell cooperates with notched racks 46 to determine the angular position of the shell.
Patent GB-1484005-A (GB)
Title: Land vehicle wheel suspension arrangement
IPC: B60G17/06
Filed: 1974-08-16
Abstract: 1484005 Controlling suspension stiffness LUCAS INDUSTRIES Ltd 16 Aug 1974 [21 July 1973] 34861/73 Heading F2S [Also in Division B7] The invention relates to a land vehicle suspension in which each wheel carrier is mounted for movement relative to the vehicle body and is resiliently biased by spring means arranged between the wheel carrier and the body, stiffness varying means being provided for selectively operating on the spring means or on damping means associated therewith to vary the dynamic stiffness of the suspension. The invention provides a control device comprising means sensitive to the direction in which the wheel carrier is displaced from a datum position relative to the body, means sensitive to the direction in which the wheel carrier is moving relative to the body, and means actuable by the direction sensitive means for operating the stiffness varying means to stiffen the suspension when the directions are the same, and operating the stiffness varying means to soften the suspension when the directions are opposite.  As shown the vehicle body is mounted on a wheel carrier 11 by two torsion springs 15, 16 in series. An electromechanical (not shown) or fluid operated mechanical lock 17 takes the spring 16 out of action by connecting the spring 15 directly to the vehicle body to stiffen the suspension whenever the wheel 10 is moving away from a moan position with respect to the body. The lock 17 is controlled by the net signal from two valve spools 23, 24. A roller 21 on a shaft 19 coupled to the arm 11 by a linkage 20 displaces the spool 23 upwardly or downwardly according to whether the arm 11 is moving clockwise or anticlockwise at any given instant. A cam 22 on the shaft 19 displaces the spool 24 upwardly or downwardly according to whether the arm 11 is above or below its mean position. Thus when spools 23 and 24 are both raised or both lowered the lock 17 is applied to cut out the spring 16, but when one spool is raised and the other lowered the lock 17 is released to soften the suspension. The response of the control device is modified during vehicle braking (see Division B7). Alternative arrangements The springs of the suspension may act in parallel rather than in series, the lock controlling the connection of one spring to the body, the suspension being stiffened when the lock is applied. The springs may be pneumatic or hydropneumatic springs, with the lock in the form of a valve controlling fluid communication between the springs. The suspension may be a single spring acting between the body and the carrier in parallel with a pair of dampers in series, with the look applied at the interconnection of the dampers to cut out either damper.

Abstract: 1,008,460. Freeze drying apparatus; refrigerating. J. L. ACHUCARRO. Aug. 26, 1964, No. 35013/64. Headings F4G and F4H. Apparatus for freezing and subsequent sublimation of a liquid or semi-liquid substance in containers 64 ... 67, Fig. 4, which are maintained in a drying chamber formed from two non-parallel cylinders 1 and 2 between the walls of an inner vessel 44 which is cooled by the introduction of a liquid refrigerant and an interspace canister 56 mounted between the vessel 44 and chamber 2. The refrigerant is introduced into the vessel 44 from a condenser container 37 in the chamber 1 through a pipe 42 when the drying chamber is pivoted as a whole from the erected position shown in Fig. 4 to the inclined position shown in Fig. 5, about an axle-cum-vacuum line mounted in bearings 15. The vessel 44 is adapted for rotation in the inclined position by a crank handle 48 in a lower ball bearing 54 and on the containers 64 ... 67 which are of a rigid substance, e.g. glass so that the containers rotate about their own axes and the axis of the vessel contemporaneously. The containers are in contact with the refrigerated vessel wall so as to freeze the material therein as shells on the container walls, and thereafter the drying chamber is pivoted as a whole to the erected position. The chamber is evacuated by a rotary vacuum pump until the desired saturation vapour pressure of ice at the desired temperature is obtained and the apparatus is tilted in the opposite direction, Fig. 6 (not shown) so that the refrigerant flows by gravity back to the condenser container 37. Thereafter the apparatus is re-erected and heat for sublimation provided, e.g. from ambient air, electrical resistances about the chamber 2 and/or in the vessel 44, heated liquid in the vessel 44 or forced air convection therein.

As described, the powdered roll 12 and a chain sprocket 13 are connected to a driven shaft 14 and the idler roll 15 is rigidly secured to a shaft 16 which has a chain sprocket 17 mounted on it via the free-wheeling device 18, which transmits drive to the shaft 16 in a clockwise sense only, as seen in Fig. 1 (not shown). The sprocket 13 has fewer teeth and thus runs faster than sprocket 17, to which it is connected by a roller-chain (19, Fig. 1) passing around jockey pulleys (20). In operation, the freewheeling device 18 transmits the drive positively to the idler roll 15 on starting up, and thenceforth maintains its speed at slightly less than that of the roll 12.
