Title: Improvements in or relating to door locks
IPC: E05B55/00
Filed: 1952-07-04
Abstract: 734,517. Locks. HELFENSTEIN, M. July 4, 1952 [Dec. 15, 1951], No. 16796/52. Class 44. In a door lock of the type having an inner and an outer handle arranged on the same spindle axis, a latch bolt is provided as sole closure element, the shifting of which is exclusively effected by the door handles and control means are adapted to be operated by actuating the inner door handle to bar the outer door handle which may be released from the outside by means of a key, or to bar the outer door handle, by corresponding setting of the inner door handle by means of a control member, so that its release by means of the key is not possible. As shown, an inner door handle 4 is rotatably mounted on a spindle 2 to which is rigidly connected an outer handle 3. A control disc 6 is carried by the handle 4 and a main lever 5 is carried on a square portion of the spindle 2. A nose 5c on the lever 5, serves to move the latch bolt 9 against a spring 8. A locking lever 10 is journaled on a pin 18 on the lever 5 and cooperates with a member 11 rigid with a toothed wheel 13 journaled on a shaft 12. The toothed wheel 13 meshes with a pinion 17 attached to a key-operated lock cylinder. A sliding bolt 14 is movable into the path of the bolt 9 by the member 11. In operation, both handles may be operated from the position shown in Fig. 1, i.e. the door can be opened from the inside or the outside of the room. In order to lock the door from the outside, the pinion 17 is turned by the key through 360 degrees to the Fig. 4 position, to move the bolt 14 into the blocking position shown. In this position also, neither of the handles can be operated. To lock the door from inside the room, the inner handle 4 is turned anticlockwise through 120 degrees, thus moving the disc 6 which rotates a lever 21 to engage a lug 21b thereon with the tail of the bolt 9 to lock the latter in the shot position. If the handle 4 is turned through 90 degrees only, the lever 10 and member 11 engage each other to prevent movement of the lever 8 and the outer handle 3, but not the bolt 9, which is retractable by the outside handle only after the key has been turned through 180 degrees in the opening direction to release the lever 5. In this position the key can only be removed after the pinion 17 has been restored to the position shown in Fig. 1.

IPC: C13B25/02
Filed: 1953-06-18
Abstract: may be used. The gas is supplied at low pressure to the chamber and the resultant depression at the core of the vortex aspirates froth from a container 1. The liquid and gas discharged through the outlet 8 are collected in a radially symmetrical vessel 10 where the separation continues. Liquid and gas are discharged from the vessel through outlets 12, 11 respectively. In a modification (Fig. 3, not shown), the rotation chamber is disposed with its outlet uppermost at the bottom of the receiving vessel which has an axial gas outlet at the top and a tangential liquid outlet at the bottom. Suction applied to the outlets of the vessel causes gas to be drawn into the rotation chamber to form the vortex and the depression at the centre of the vortex draws froth into the chamber. In a further modification (Fig. 4, not shown), the rotation chamber and the receiving vessel form a cylindrical unit having a horizontal axis. Before separation the froth may be separated from liquid by the method described in Specification 734,460. A screw conveyer may be used to facilitate the supply of stiff froth to the core of the vortex. Dimensions are given in the Specification.

Abstract: 1,007,113. Pushing and pulling jacks. GULLICK Ltd. March 18, 1964 [May 2, 1963], No. 17301/63. Heading B8J. A conveyer C in a mine is pushed over by a short double-acting ram, comprising a cylinder 14 and piston 15, carried on a base 10 on which are hydraulic props 11, 12 supporting a roof bar 13. After pushing over the conveyer C the ram is used to advance the base 10 up to the conveyer. An elongated rigid bar 16 is attached to the conveyer C at 17 and extends into the base 10 in which it is free to slide. A belt 16a with a small amount of slack is attached to the bar 16 at each end 18, 19 and passes between a ram 22 and an anvil 23 of a clutching device with an hydraulic cylinder 21. To advance the conveyer pressure fluid is fed to the cylinder 21 so that the belt 16a is clamped between the ram 22 and anvil 23. A sequence valve (not shown) then allows pressure to build up behind the piston 15 so that the belt 16a and bar 16 are advanced a short distance equal to the stroke of the piston 15 thus advancing the conveyer C. At the end of this stroke ram 22 is released and piston 15 retracted without moving the belt 16a or bar 16. This cycle is repeated until the conveyer has been advanced step-by-step the required amount. To draw the base 10 carrying the props 11, 12 and roof bar 13 up to the conveyer C the action of the piston 15 is reversed with respect to the action of the ram 22. The several necessary short strokes of piston 15 and ram 22 are caused to take plaee automatically by valve mechanisms (not shown).

Abstract: 239,832. Soc. Anon. des Etablissements Duchesne et Cie. Sept. 13, 1924, [Convention date]. Pendulum-weight apparatus; sliding-weight apparatus.-An automatic indicating apparatus for a weighing balance comprises two pendulumlevers, the first moving a pointer across a graduated scale, and the second entering into operation to retract the pointer at the termination of its stroke, by displacing a sliding member which drives a counterweight along an unstable beam, the stopping positions of the sliding member being determined by notches frictionally engaged by a bolt, the beam and the two pendulum-levers being operated simultaneously under the effort transmitted by a single rod. The load on the balance pulls down a rod 1 connected to a lever 2. One end of the lever is coupled by a rod 3 to a pendulum-lever 4 bearing an indicating pointer 5, and bv a rod 9 to a beam 10. The other end is coupled bv a rod 16 to a pendulum-lever 15 provided with ,a slotted arm 17 for moving a sliding member 18. A fork 19 on the sliding member drives a counterweight 11 along the beam 12, and a rack 18' actuates number discs 24, 25. When a load not exceeding one kg. is placed on the balance the pull on the pendulum-lever 15 is insufficient to liberate the sliding member 18 from the bolt 22, and the weight is automaically indicated by the pendulum-lever 4 and pointer 5. When the load is between one and two kgs. the sliding member 18 is forced to the left, the bolt 22 engages the next notch, and the counterweight 11 is moved so as to balance one kg. of the load the fractional part being indicated by the pointer 5. At the same time, the rack 18<1> rotates the number wheels 24, 25 so as to display numerals 1 and 2 through the orifices 7, 8 respectively. Similar operations occur for weights above two kgs.
