Patent GB-2059600-A (GB)
Title: Touch switch device
IPC: H03K17/22
Filed: 1980-10-06
Abstract: A touch switch device includes a touch plate 3 or other touch member arranged, when touched, to interrupt the passage of an oscillating signal from a DC powered oscillator 31-34 to a charging circuit 36-39, including a capacitative store 38. The charging circuit responds to this interruption to initiate discharge of the charge store 38, and a control, including an inverter 44 and a flip-flop 46 controls a switch 48 to change from one state to another upon a change of charge state, in this case a recharge, of the charge store 38. A circuit 51-54 supplies a reset signal to the flip-flop 46 during an initial preset period immediately following the switching on of power to the device, to inhibit this change of state of the switch 48 during such period. <IMAGE>

Title: Control valve assembly
IPC: B60T8/28
Filed: 1981-08-24
Abstract: An apportioning valve for controlling the pressure applied to the rear brakes of a vehicle comprises an inlet (15) (40) to receive actuating fluid and an outlet (14) (41) for connection to the rear brakes. The inlet (15) and outlet (14) are normally connected via inlet chamber (13), passage (22), apertures (23), chamber (24), valve seat (28), and chamber (12). An auxiliary chamber (29) is connected to the inlet chamber (13) via a throttle (31) and to a vent valve seat (35) communicating with a one- way valve (34). A pendulum (3) is biased against the valve seat (35) during deceleration and thus closes the valve seat (35) and allows pressure to build up in auxiliary chamber (29). When pressure in auxiliary chamber (29) is sufficiently high pistons (9 and 10) under outlet and auxiliary chambers pressure respectively move to the right to bring valve seat (28) against closure member (25) to isolate the inlet (15) from the outlet (14). In an air/hydraulic brake system (Fig. 2) the pneumatic pressure piston (9) and valve (28) are replaced by an extension (44) of the piston (10) subject to hydraulic braking outlet pressure and a hydrualic shut-off valve (43) between inlet (40) and outlet (41) controlled by the extension (44). <IMAGE>

IPC: C08F8/00
Filed: 1981-12-14
Abstract: Macromolecular compositions cross-linked by a new sequence having the formula -NR<sx>s-CH = N-CO-. The new sequence is obtained by reacting a macromolecule, in particular a polymer macromolecule, which contains at least two aminocarbonyl groups, with a compound containing at least two formylamido groups, in a strongly acid aqueous medium. This new sequence is formed through a chemical reaction according to the following equation:  (FORMULA)  The compositions according to the invention, containing on the one hand macromolecular compounds which have at least two amidocarbonyl groups, and containing on the other hand a compound which has at least two formylamino groups, may be used as thickening agents or as gelatinizing agents for water-diluted acids. Following the mixing of these components, in the presence of water-diluted acids, a cross-linking reaction takes place as described above, and results in the new sequence which forms the cross-linking bridge. The acids so thickened of gelatinized are preferably used in oil and natural gaz extraction from underground fields.

Title: Lubricating system
Inventor: WEGMANN JEROME B
IPC: F04B47/02

Abstract: A lubricating system for a walking beam oil well pumping unit comprising an assembly of a series of divider valves (S) for delivering metered quantities of lubricant to points of lubrication (e.g. 5, 17) of the unit, a lubricant pump (27) for supplying lubricant to the valves, and a lubricant reservoir (21) for supplying lubricant to the pump, the assembly being mounted on the walking beam (3) of the pumping unit, the pump being operated by the oscillation of the beam. One of the divider valves in the series delivering lubricant to line L1, is adapted to deliver a substantially higher volume of lubricant than others of the valves on each operation thereof and is interconnected with the pump for delivery of its output back to the pump for recirculation. The other valves are adapted for delivery of their outputs to points of lubrication of the unit. The displacement of the said one valve is such in relation to the displacement of the others that, over a predetermined period of time of operation, the one valve returns to the pump a major fraction of its total output in that period and the other valves deliver to the points of lubrication only a minor fraction of the total pump output. <IMAGE>

Patent GB-2141264-A (GB)
Title: Fuel injection pumping apparatus
Inventor: SKINNER ROBERT THOMAS JOHN
IPC: F02M59/38
Filed: 1984-07-16
Abstract: A fuel injection pumping apparatus of the rotary distributor type has a distributor member 11 which is also axially movable to determine the allowed outward movement of the pumping plungers 13 and hence the amount of fuel supplied to the associated engine. The extent of outward movement is determined by inclined stop surfaces 22 which co-operate with complementary surfaces on shoes 14 associated with the plungers. In order to minimize axial movement of the distributor member when the shoes engage the stop surfaces a chamber 44 to which liquid is supplied to vary the axial setting of the distributor member, is locked off from fluid supply and drain passages, by a servo valve 41 when the correct position of the distributor member is obtained. A hydraulic lock is thus created in the chamber. Pressure in chamber 44 acts against a spring 48 to allow member spring 49 to move the distributor 11. The spring 48 acts on an annular member 45 forming a seal with a part of the distributor or, as shown a housing 39 fast with the distributor. <IMAGE>
