Patent GB-2095001-A (GB)
Title: Improvements in control valves for vehicle hydraulic systems
IPC: F15B1/027
Filed: 1982-03-08
Abstract: A control valve assembly incorporates a flow control valve (10), and a piston (8) which are both biassed in the same direction against pressure in an hydraulic accumulator (4) by respective springs (20) and (12). Accumulator pressure in a control chamber (24) also acts to urge the flow control valve (10) in the same direction as it is biassed by the spring (20) and pressure from a pump (P) acts to bias the flow control valve (10) in the opposite direction. A pilot dump valve (26) controlling communication between the chamber (24) and an outlet connection is normally biassed into a closed position by means of a third spring (28). The dump valve (26) is adapted to open at a cut-out pressure to dump pressure from the chamber (24), and the cut-out pressure is determined by the area (A2) of the seating (29) of the dump valve (26) over which the pressure in the chamber (24) acts, and the force in the third spring (28). A cut-in pressure at which the dump valve (26) closes is determined by the area (A1) of the piston (8) and the force in the spring (12). <IMAGE>
Patent GB-2097498-A (GB)
Title: Train braking systems
IPC: B60T13/66
Filed: 1982-04-19
Abstract: In a train braking system in which train pipe pressure is varied by a brake controller of the joy-stick type which has a central running position, and brake application and release positions, a logic system ensures that on initial movement of the joy-stick control towards the brake application position an initial predetermined drop of pressure results. The logic circuit 18 in Fig. 2 is connected to a joy-stick controller 17 which operates an application magnet valve 12 and a release magnet valve 14. In the running condition the brake controller is in its central position and switch S1.1 is closed, and the release magnet valve 14 is energised. Thus the equalising reservoir is charged to 5.0 Bar. If the brake controller is moved, even briefly, to the application position the logic circuit assumes the state shown in Fig. 2B in which S1.1 opens and RL1 is de-energised which opens RL1.1. Thus the release magnet valve 14 is de-energised and the equalising reservoir is vented through the application magnet valve 12 which is itself de-energised. The pressure in the equalising reservoir 11 continues to fall until it reaches 4.6 Bar when PS1 opens and de-energises RL2. This opens RL2.1 and RL2.2 which causes the application magnet valve 12 to be energised, thus stopping the continued exhausting of equalising reservoir 11. <IMAGE>

Title: Depth gauge for handsaw
Inventor: LAIDLAW ALEX DUNCAN
IPC: B27B21/08
Filed: 1982-08-13
Abstract: A guide member (2a) carries a pair of spaced upstanding strips (4, 6) each defining a slot (4a, 6a) associated with a clamping member (8).

Title: Detecting hydrogen induced fissures in metals
Inventor: BATHMANN HANS-JURGEN
IPC: G01N29/44
Filed: 1982-09-02
Abstract: The invention relates to a method for the detection of hydrogen- induced fissures in metallic materials. The invention is characterized by the combination of an ultrasonic testing method and evaluation method connected with it, whereby a workpiece is scanned in detail using ultrasonic test heads with separate transmitter-/receiver -oscillators. The workpiece may be scanned fully volumetrically and the readings brought about by hydrogen- induced fissures recorded, while at the same time a sensitivity adjustment is carried out, dependent on running time. With a preset sensitivity setting, through recording of the reading levels the evaluation scale for the detection of the reading ranges on completion of the test is freely selected, and through projection of the reading ranges onto the scanning surface the reading surfaces are determined and related to the total surface scanned. <IMAGE>

Title: Centrifugally moulded concrete products
Inventor: EIMATSU KAITO
IPC: B28B21/30
Filed: 1982-12-23
Abstract: A core (7) is insertable into a rotary mould (15), and fresh concrete is charged into the rotary mould to fill the annular gap (S) between the wall of the rotary mould and the surface of the core. After filling the annular gap, the core is withdrawn leaving a layer of fresh concrete of a uniform thickness on the inner peripheral surface of the rotary mould. The latter is then rotated at a predetermined speed to apply a centrifugal force to the fresh concrete to form the desired hollow concrete product, such as a pile or post. The insertion and withdrawal of the core into and out of the rotary mould is conducted by moving a truck (16), (Figure 5, not shown) carrying the rotary mould linearly towards and away from the core which is held stationary. <IMAGE>
Patent GB-2140506-A (GB)
Title: Starting piston engines
Inventor: PARKIN THOMAS ALBERT
IPC: F02B3/06
Filed: 1983-05-25
Abstract: Large marine diesel engines can be started by supplying compressed air sequentially to the engine cylinders. In a known arrangement, the air is fed from a manifold 26 to the respective cylinders via pneumatically-actuated valves 28 which are actuated in sequence by an engine-driven pneumatic distributor 34. The valves 28 are heavy and thus sluggish in operation, especially when closing. To take account of this sluggish operation, the invention provides for the signal to each valve 28 to close that valve to be advanced with respect to engine position as the engine speed increases. Preferably, the signal to each valve 28 to open that valve is also advanced, but to a lesser extent than the closing signal. <IMAGE>
