Patent GB-694833-A (GB)
Title: Improvements relating to valves or taps
Inventor: ACKERMANN GOTTLIEB
IPC: F16K31/52
Filed: 1951-08-21
Abstract: 694,833. Valves. GOTTLOB MACK & RHEINHOLD BACHOFER. Aug. 21, 1951, No. 19741/51. Class 135 A valve comprises a closure member 4, Fig. 1, movable by a stem 3, which slides in the body 1, to engage a seat 7, the member carrying a resilient seal 5 having a recess 9 surrounded by a peripheral lip 10 whereby inlet pressure urges the lip against the seat when the valve is closed. The stem is movable by an eccentric pin 13, which so limits the stroke of the closure member that negligible force is exterted by the seal against the seat, the pin extending from a rotatable boss 12 having a handle 11. A resilient sleeve 17 surrounds the stem and is fitted in compression so that when the valve is closed, inlet pressure acting on the seal 5 is substantially counterbalanced. In a modification, the seal is formed as the seat, and urged by inlet pressure against a non- resilient closure member when the valve is closed. The valve body may be formed with a straight passageway in which the closure member co-acts with an inclined seat. In another arrangement, the seal and resilient sleeve are in one piece and the valve closes in the direction of flow. In a further arrangement, the closure member comprises a resilient disc 48, Fig. 6, having a peripheral lip 50, pressed against a seat 47, by inlet pressure when the valve is closed, the spindle 51, being sealed by a diaphragm 53, so dimensioned that inlet pressure acting on it counter-balances the inlet pressure acting on the member 48. In yet another arrangement, the spindle is sealed by a diaphragm inserted under compression to balance the inlet pressure on the closure member. The eccentric pin may be replaced by a pin movable in a helical slot in the body.

Abstract: 147,779. Apple, V. G. April 23, 1917, [Convention date]. Turning-gear.-In an electric starting, lighting, and ignition apparatus for motor-vehicles, a dynamo 18 serving also as a starting-motor has its armature shaft 33 in line with the engine shaft 17 and coupled directly to it by a flexible coupling such as a pair of springs 55, 56, so that, when starting, the armature can turn through at least part of a revolution before the load is picked up. The springs terminate in eyes 60 passed over transverse bolts 54, 17', the bolt 17' also securing a fan pulley 64 to the engine shaft. The field frame 20 of the dynamo is secured by means of lugs 21 to a plate 25 which secures together a cross-member 19 and the front spring of the vehicle. The armature shaft turns in ball bearings in a hub 36 of the frame 20 and parses through a support 27 mounted on the plate 25 and having a conical extension 31. The poles 76 of the dynamo have shunt field windings 77 and differential compound field windings 78. The armature core 72 has conductors 73, 74 and the commutator 75 is engaged internally by brushes 91 in the hub 88 of an insulating plate 80, which closes the front end of the field frame and carries conducting rings 97, 100 connected to alternate brushes 91. The ring 97 is also connected to the field coils and to a switch terminal. An axial opening in the plate 80 is fitted with a current regulator 106, which can be removed to admit the hub of a starting-handle having a clutch for engagement with pins 43 on the armature shaft. The Specification as open to inspection under Sect. 91 (3) (a) describes also a switch, Fig. 11 (Cancelled), for controlling the dynamo circuits. This comprises a foot-actuated plunger 211 carrying a bridge-member 253 of insulating material with a conducting strip 218. In the lowest position of the plunger 211, the strip 218 bridges contacts 219, 220, and the battery cells are connected in series to the field of the dynamo, which is run as a motor to start the engine. When the foot pressure on the switch plunger is relieved, the plunger is raised by a spring 213 to the position shown in Fig. 11, and the dynamo runs as a generator. In the uppermost position of the plunger, the various terminals are disconnected. The plunger is retained in the upper and lower positions by ball detents 215 engaging recesses 217 in a boss 214 on the plunger. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1377597 Splitting ARDOISIERES D'- ANGERS SA and B VIEMON 26 April 1973 [26 April 1972] 19973/73 Heading B5E A method of clearing laminated material, such as slate shale, comprises applying pressure to the opposed faces of a block which are substantially parallel to the cleavage plane without drawing the opposed faces of the block apart; which pressure is less than that applied in a selected cleavage plane. A device for carrying out the method comprises a pair of plates 10, 11 having seals 12, 13 adjacent the edges of the plates and which can be brought into abutment to form a sealed enclosure E, the extent of engagement of the seals being determined by adjustable screws 15. The plates are formed with a stepped shoulder 22 whereby a part p of a block B to be cleaved placed within the enclosure is outside the enclosure. A vacuum is applied to the enclosure through connections 17, 18 in the plates to cause forces F, F1 to press the seals together. Before, during or after evacuation of the enclosure, a fissure 25 is started by a chisel in the cleavage plane to permit atmospheric air or other fluid to act in the plane to separate the block. To reduce leakage from the enclosure, each plate may be covered with porous foam. A fluid under pressure may be applied to the fissure and the enclosure may or may not be subjected to a slight vacuum.

Abstract: 1,020,179. Switch contacts. SCHEUBECK, [trading as MASCHINENFABRIK REINHAUSEN GEB SCHEUBECK KOMM. GES.]. May 15, 1964 [May 17, 1963], No. 20322/64. Heading H2B. A contact bridge 4, carrying contacts 5, 6 co-operating respectively with fixed contacts 2, 3 on a base 1, is pivotally mounted, at 8, on a support 7 and is laterally supported by compression springs 9, 10. In a new switch the thrust of the two springs 9, 10 and the pivot 8 are in alignment, but if burning of contact pair 2, 5 has occurred, as shown, the displacement of the bridge 4 relative to the support 7 results in the springs tending to turn the bridge counterclockwise and thus, when the switch is opened, contacts 3, 6 tend to open first. This results in the greater part of the arcing occurring at these contacts and thus they burn away more rapidly until both contact pairs are burnt away equally and thus even burning of the contacts is maintained throughout the life of the switch.
