Filed: 1971-08-18
Abstract: 1304305 Casting machines MAHLE-WERK GmbH 18 Aug 1971 [26 Aug 1970] 38674/71 Heading B3F In a pressure die casting machine in which the mould halves 22 and 21 are moved together by an hydraulic drive acting through a toggle linkage 14, the injection of the casting material into the mould is initiated only if the pressure developed in the cylinder 16 of the hydraulic drive reaches a predetermined minimum. The machine has switch devices 40, 50, 60 and 70 provided with switches 41, 51 and 52, 61 and 71 respectively. Switch 71 is open when the mould is completely opened and is otherwise closed. The switch 41 is closed by a cam 19 when the mould halves are normally just in contact with one another. Switches 51 and 52 are opened and closed respectively when the hydraulic drive has reached the position in which the toggle lever mechanism is completely extended i.e. when the mould is normally fully closed. The switch 61 is closed when the pressure in the cylinder 16 reaches a predetermined minimum. This pressure corresponds to a maximum pressure which is developed in the cylinder 16 shortly after the mould halves just contact one another but before the toggle lever mechanism is fully extended. When the machine is operating normally, the switches 41 and 61 close thus energizing the relay 80 which in turn closes the switches 81 and 82; the relay will now remain energized even if the switches 41 and 61 open again. When the toggle is completely extended, switch 52 closes and energizes a contactor 90 which in turn closes switch 91 and operates a solenoid to initiate the injection of molten material into the mould. If for any reason the pressure in the hydraulic cylinder 16 does not reach the required minimum value, switch 61 does not close, thus preventing energization of the relay 80 and-injection of the casting material.

Abstract: 892,797. Clamp fastenings. BULLOWS, W. D. Sept. 19, 1960 [Nov. 23, 1959], No. 39615/59. Class 44. In a clamp of the kind including a pair of members 7, 8 adapted to be mounted for pivotal movement relative to one another and each having a convex arcuate toothed face 18, 19 and resilient means 12, 13 for loading the members towards a position in which a rope, cable, chain or the like can be gripped between the arcuate faces, one of the arcuate faces 8 has formed thereon a projection 22 which is so shaped that when the rope, cable, chain or the like is gripped in the clamp a pull exerted on the rope, cable, chain or the like against the projection in one direction will move one or both of the members against the resilient means and allow the rope, cable chain or the like to be withdrawn from the clamp but a pull exerted on the rope, cable chain or the like in the opposite direction against the projection will cause the members to grip the rope, cable chain or the like more tightly. As shown the members 7, 8 are mounted on spigots 5, 6 which are integral with a base 4. They are retained in position by washers 10 and screws 11 The projection 22 is a lip which overlies the teeth on the member 7, the member 7 having a cut away portion 23 to accommodate the lip. Both the lip 22 and portion 23 are chamfered to facilitate the introduction of the rope, cable, chain or the like between them and the projection is also formed with a pronounced shoulder against which the rope, cable, chain or the like bears in the direction which causes the members to grip it more tightly. Each member is formed with a finger piece 25, 26 which enables the members to be moved in their releasing directions and each finger piece is shallow enough to enable the rope, cable, chain or the like to be passed underneath it. This enables a reverse pull to be exerted on the rope, cable, chain or the like without it coming into contact with the projection 22 and thereby becoming disengaged from the clamp. In a modification the two members are geared together, only one of the members is spring loaded and only one has a finger piece. In a further modification the base is a fixed part of a boat or the like.

Title: Safety apparatus for use in a vehicle to restrain the movement of an occupant
IPC: B60R21/02
Filed: 1973-08-30
Abstract: 1444279 Vehicle safety apparatus ACCLES-BRITAX Ltd 29 Aug 1974 [30 Aug 1973] 40842/73 Addition to 1367876 Heading B7B In a vehicle safety apparatus a rigid arm 1 rotatably mounted at one end in a shaft 2 and having a pad at the other end for acting against the occupants chest is locked when the footbrake system is operated. As shown a lever 5 attached to the lower end of arm 1 is pivotally connected to a recoiless energy absorption means comprising a collapsible tube 7 which may operate by turning bulging inside out or by causing extrusion. The tube 7 is pivoted to a bar 9 which slides longitudinally in bearings in the housing 3. The arm is stored in the inoperative position shown at 29 by a hook portion 38 engaging a roller 52 supported on bar 9. When the occupant is seated and the ignition switch turned on, solenoid 49 is energised to disengage hook portion 38 from roller 52 by means of rod 48 and lever mechanism 44, 41. Arm 1 is then biased by spring 23 whose free end is fixed to block 26 on bar 9 to rotate about shaft 2 for moving the pad towards the occupant's chest. A limit switch 53 is actuated upon travel of roller 52 with arm 9 to de-energise solenoid 49 thus preventing battery run down. Cylinder 30 and piston 31 connected to spring block 26 control the final movement of arm 1 so that the pad is positioned gently against the occupants chest. Other damping means such as a roller or brush engaging a friction member at the final movement of the arm 1 towards its operative position may be used. Alternatively a portion of lever 5 is adapted to support a cam with a doubly inclined surface and a spring attached to housing 3 is arranged to engage the cam surface. If the vehicle is subjected to deceleration or acceleration mass 16 located on a pivoted carrier 17 moves to raise a pawl member 13 to cause locking engagement between teeth 12, 15 thus locking bar 9 and arm 1. Further movement of arm 1 causes tube 7 to deform to retard the occupant's forward movement. When the vehicle is driven at low speeds mass 16 may not be exerted sufficiently to cause locking when the footbrake is operated. In this case solenoid 22 is energised on depression of the footbrake to draw pushrod 21 which moves carrier 17 and bar 9 is locked by pawl 13. A replacement cover provided in housing 3 allows for maintenance and replacement of sleeve 7.

The gas output of the turbine is connected to a tube bank 29 which is located in a terminal heat exchanger 30. The exchanger 30 comprises a draft stack 34 of the natural draft-type, or of the type where air is supplied by a fan 36 that is driven directly by the turbine through reduction gearing or electrically by current produced in a generator 44 that is connected to the turbine; or, alternatively, the coolant may be water. The inert gas from the tube bank 29 is fed through a compressor 38, driven by the turbine, before being returned to the tube bank 24. The secondary sodium from the tube bank 12 is cooled in a heat exchanger 16 that contains the tube bank 19 of a steam generating means (not shown). The turbine may drive sodium pumps 10 and 18 and a water pump (not shown) of the steam generating means. The exchanger 8 may be integral with the reactor. In operation, the higher the temperature imparted to the inert gas in the tube bank 24, the faster the turbine is driven and there is a corresponding improvement in the cooling effect.
