Title: Seats
IPC: A47C7/46
Filed: 1979-09-01
Abstract: A vehicle seat includes a variable stiffness zone in the region corresponding to the lumbar region of a seated occupant to reduce discomfort when seated for prolonged periods. The variable stiffness is provided by a laminated springy rod (16) of elongated cross-section which extends transversely of the seat and is angularly adjustable so that its stiffness as experienced by the seat occupant varies with its angular setting. The rod (16) is enclosed within a sleeve (30) of plastics material and cooperates with a plate which bears against the backrest upholstery to transmit the load exerted by the occupant to the rod (16). Such an arrangement has the advantage that the contour of the upholstery remains unaltered by adjustment of the rod (16). <IMAGE>

Title: Sheet counting apparatus
IPC: G06M9/02
Filed: 1979-11-29
Abstract: The invention relates to apparatus for counting flexible sheets contained in a stack, such as a pile of banknotes. The apparatus is of the type which has a rotary sheet removing assembly including a number of suction organs to which vacuum is applied in sequence and which contact the side face of a free end of a stack of notes to deflect each note from its initial position and count it. Normally after the machine has stopped and is to be restarted the rotary assembly is moved backwards until one of the suction organs is in the appropriate place to move the next sheet. This presents problems when handling soft or warm sheets. The invention involves rotating the rotary sheet removing assembly slowly in a forward, i.e. running direction, prior to the commencement of the sheet counting operation until each organ is effectively positioned in line with the face of a stack. In the drawing (Fig. 1) the rotary sheet removing assembly (2) is driven by an electric motor (30) through a gear box (GB) driving through a pulley (8) and driving band (6). The special gear box (GB) is so designed that when the motor (30) rotates in one direction it drives the pulley wheel (8) at one speed and when the motor is reversed it drives the pulley wheel (8) in the same direction but at a slower speed. <IMAGE>

Title: Plasticising and impelling Particulate Materials
IPC: B29C48/03
Filed: 1979-12-18
Abstract: A rotor having at least one peripheral annular channel (24) is rotatable relative to a stator surface of a surrounding stationary housing to impel material in the channel from an inlet (28) through the housing, to a circumferentially spaced outlet (36), through which plasticised (liquid) material is discharged by pressure developed by the material being impelled against a first stationary surface (34) which projects into a channel downstream of the outlet (36). A second surface (40), upstream of the outlet (36), has a clearance with the walls of the channel (24) and restrains advance of (unmelted) material (39) in the centre of the channel while permitting liquid material (25) to be dragged towards the first surface (34). The channel space (46) between the first and second surfaces (34 and 40) enables the discharge pressure to be generated in an accumulated pool (42) of the liquid material. The second surface (40) may be provided on an extension along the channel of part of the member (32) which defines the first surface or may be provided on a further member (38), which may be of various different configurations, and may act as a scraper against one channel wall. <IMAGE>
Patent GB-2047752-A (GB)
Title: Laundry or dish-washing machine
IPC: D06F33/36
Filed: 1980-02-25
Abstract: In a laundry or dish-washing machine, a thermostat compares the temperature of the washing liquid with at least two control temperatures which can be selected by the user independently of one another. The change of state of the thermostat output controls the advance of the washing machine programmer when the washing liquid has reached the lowest of the control temperatures. This allows the user to set a different washing temperature from that determined by the programmer. In one embodiment, Figure 2, a temperature transducer Rt immersed in the washing liquid comprises a resistor with a negative temperature coefficient and is included in a resistor bridge connected across a constant voltage source U. The transducer Rt supplies a voltage Vt which decreases as the liquid temperature increases. The thermostat comprises two voltage comparators IC1 and IC2 which each at their non- inverting inputs receive the voltage Vt and at their respective inverting inputs two control voltages VC1, VC2 which vary in inverse proportion to the two selected control temperatures. The outputs of the comparators IC1 and IC2 are interconnected and their output signal (voltage VS) controls the advance of the programmer when the voltage Vt reaches the value of the higher of the two voltage VC1, VC2. <IMAGE>

Title: Pressure reducing device for vehicular hydraulic brake systems
IPC: B60T11/34
Filed: 1980-06-12
Abstract: A pressure reducing device for vehicular hydraulic brake systems. A casing (1, 2) is provided with an inlet chamber (8) and an outlet chamber (10) separated by a movable piston (11) on a piston rod (13). The piston rod carries an annular gasket (12) which is prestressed to form a tight seal against the piston (11) and/or the piston rod (13). The piston is spring loaded (15) towards the outlet chamber (10) which is formed with axial by-pass grooves (21) extending only part-way towards the inlet chamber (8). The gasket (12) has an outwardly inclined flexible lip (22) which contacts the periphery of the outlet chamber. When fluid pressure is applied via the inlet (7) fluid passes through the grooves (21) to apply pressure at the outlet (9). When the pressure on the surface of the piston in the outlet chamber exceeds the pressure on the reduced surface of the piston in the inlet chamber by an amount greater than the spring pressure, the piston moves towards the inlet chamber until the flexible gasket lip (22) passes the end of the grooves (21) and seals the outlet chamber from the inlet chamber. When the inlet pressure is reduced fluid can flow back to the inlet chamber past the flexible lip (22). <IMAGE>

Title: Hydraulically preloaded safety couplings
IPC: F16D9/04
Filed: 1981-11-20
Abstract: The failure of a safety coupling upon overload can be unpredictable and the present invention seeks to reduce the switch-off range which obtains under overload. This is achieved by subjecting the driver elements (2) of a coupling (3) arranged between driving members 5,6 of a pilger rolling mill hydraulically to a tensile preload which is maintained while the coupling is in use. In this way, the stress variations of the element in use are reduced. The hydraulic preload is maintained by means of an hydraulic piston/cylinder mechanism (7) mounted at one end of each element (2), which acts on a supporting tube (4) arranged between the ends. Non-axial forces on the element are avoided by the provision of symmetrical bearing surfaces. <IMAGE>
