Title: Apparatus for use in assembling small mechanisms
IPC: B23P21/00
Filed: 1966-02-11
Abstract: 1,083,442. Conveyers. SOCIETE ANONYME DE LA FABRIQUE D'HORLOGERIE LE COULTRE ET CIE. Feb. 11, 1966 [June 30, 1965], No. 6241/66. Heading B8A. [Also in Division B4] Small mechanisms (not shown) e.g. for watches, electric or electronic circuits, and computer parts, are assembled step by step, each being positioned in compartments 12 of a rotary conveyer disc 11 which functions as a rotary work-table. Parts for assembling on each mechanism are taken from a compartment 13 of a step-by-step conveyer 14, which is operated according to a predetermined programme, through an aperture 16 in a cover 15, to assemble on a mechanism in a compartment 12. The conveyer disc 11 is then indexed to bring the next compartment 12 adjacent the aperture 16 and so on. After a complete cycle of rotation of the disc 11 respective parts from the compartment 13 will have been fitted to all the mechanisms on the disc 11. The conveyer 14 is then indexed forward by one compartment and the process is repeated, assembling a different type of part to the mechanisms. Sometimes a compartment in the conveyer 14 may contain an instruction e.g. to lubricate. The bottom of such a compartment may be translucent so that the instruction is illuminated by a suitable light. It may be necessary for the conveyer 14 to be reversed a step at certain stages in the operation and subsequently advanced two steps. The programme of the conveyer 14 is determined by a punched card (Fig. 7, not shown) placed in position at 34. The disc 11 is detachable from the spindle 10 and on completion of the work on the mechanisms, may be replaced by another disc with unassembled mechanisms ready in place in the compartments 12. Indexing of the conveyer 14 after each cycle of the disc 11 is effected by a knee-operated control. Operator's elbow rests 8, 9 are provided. In a modification (Fig. 1, not shown) the conveyer 14 may be circular and concentrically disposed relative to the disc 11. It may be eccentrically arranged (Fig. 2, not shown).

Title: Improvements relating to vehicle ejection seats
IPC: B64D25/02
Filed: 1963-02-18
Abstract: 996,635. Safety harness. J. MARTIN. Feb. 7, 1964 [Feb. 18, 1963], No. 6486/63. Heading A3V. [Also in Division B7] The arms of the occupant of a vehicle ejection seat are restrained by lines 1 (Fig. 1), 20 (Fig. 3) which are tensioned during ejection. As shown in Fig. 1, each line 1 passes from an armband 2, through guides 6, 7 and a ring 9, and loops round a seat harness strap 11, so that it is released when the harness release 8 is operated. The rings 9 are connected by tensioning lines 4 which each pass through a second one way snubbing box in a housing 12, round a shear pin 13, through a second snubbing box in the housing 12 and round the leg of the occupant to a releasable fastening 16 on the seat. The shear pin 13 is connected to the floor of the vehicle (an aircraft as described) so that on ejection the arms and legs are pulled towards the housings 12 by the lines 4 before the pins 13 shear. The guides 6, 7 either comprise stitching which breaks under load or are each formed of a pair of selfadhering pile fabric strips, so that the lines 1 pull out of them during ejection. As shown in Fig. 3, each restraining line 22, 20 passes from a harness strap 27, through rings 21, 28 on the forearm and lower leg of the occupant's suit to a releasable fastening 30 by which it is connected to a tensioning line 31 passing through a snubbing box 32 to an anchorage 33 on the aircraft. On ejection the fastening 30 and line 20 are pulled through the snubbing box until the fracture either of a shear pin in the anchorage or of a weak link in the line 31.

Title: Improvements in centrifugal separators
IPC: B04B1/14
Filed: 1930-02-27
Abstract: 355,366. Centrifugal machines. FAWCETT, H. W., 3, Kent Road, Harrogate. Feb. 27, 1930, No. 6594. [Class 23.] Density separators. - Peripheral nozzles or apertures for the discharge of separated constituents are provided with means whereby their available cross section may be varied to permit the discharge ' o f matter which would normally tend to choke up the apertures. In the form shown in Fig. 1, a conical valve member 2 moves in a discharge aperture 3 in the wall 1 of the drum. The member 2 is screwed to a spindle 4 to which is pivoted a spider 7 carrying a tray 8 with a central aperture 9. One end of a pivoted lever 10 bears against the outer side of the pivot 6 and the other end carries a weight 13 with an adjustable screw 14 to limit its inward movement. When the empty separator starts to rotate, the weight 13 is thrown outwards and the valve member 2 is moved inwards until the stop 5 arrests the movement. When liquid is supplied and the apparatus functions normally, sludge is discharged through the aperture 3 into the tray 8 and part passes through the aperture 9 while the remainder flows over the edge of the tray. The member 2 then occupies a position determined by the differential action of the centrifugal forces on the weight 13 and the sludge in the tray. If the aperture 3 becomes choked the supply of sludge will decrease and the sludge will pass out of the tray. The weight 13 then moves outwards and the member 2 moves inwards. The available cross section of the aperture 3 is increased and the obstruction is flushed away. The apparatus then resumes its normal position. In the modification shown in Fig. 2, the lever 10 is a bell-crank lever which gives an increasing retractive force on the valve member 2 as it moves inwards. The valve member 2 is a cylinder with a flat surface 2a and the parts are adjusted so that the sludge normally maintains a certain level in the tray 8. A spring or float may be used instead of the weight 13.
