Abstract: 1,233,872. Filing papers. W. LENNARTZ. 27 Feb., 1970 [7 March, 1969], No. 9513/70. Heading B6E. A document file of synthetic plastics material and comprising a back sheet 7 and cover sheet 6 connected to one another by a spine fold 2, is made from a length of extruded and flattened tube 4 having thickened parts at the fold 2 and opposite edge 1, by cutting at 5 along the edge 1. The cut 5 may extend only part way along the edge 1 so as to leave a folded part 12, Fig. 3, which serves as an additional support for documents in the file. Further the bottom edge 11 or parts thereof may be sealed. A strip of material carrying flexible filing prongs may be attached by welding to the inside of the fold 2, or such strip together with the fold part 2 may form a passageway receiving a suspension bar. As shown in Fig. 6, a nose 23 and recess 24 for engaging a suspension rail are formed in the thickened part 22 at the spine fold. The paper filing means may be attached to a strip of material which can extend into the thickened part 22 to act as a reinforcement.

Abstract: 1,234,561. Automatic acceleration and speed control. SEVCON ENG: Ltd. July 1, 1968 [March 30, 1967], No.14566/67. Heading G3R. A system for controlling the acceleration and deceleration of an electric motor comprises separate networks 9, 10 for providing acceleration and deceleration reference signals, a circuit 6 providing a signal dependent on the acceleration of the motor 1 and a comparator 7 which provides an output signal to control a power supply 3. The D.C. motor 1 has a brake 4, whose effort is inversely proportional to the motor current, and drives a tacho-generator 5 the output of which is differentiated at 6. The two networks 9, 10 provide reference signals for acceleration and deceleration respectively the appropriate one being connected to the comparator 7 by a switch 8; the values of these signals are adjustable by manual controls 11, 12. The output of the comparator 7 is amplified at 13 and used to control a variable pulse ratio power regulator 3 feeding the motor. Alternatively, Fig.2 (not shown) the amplifier (13) drives a servomotor (15) controlling the throttle of an engine (16) driving a variable voltage generator (17) feeding the motor. If an A. C. induction motor is used the regulator 3 is replaced by a variable frequency generator. The brake 4 may be energized is parallel with the motor or a continuously acting brake may be used; plugging or regenerative braking may alternatively be used. The tachogenerator may be replaced by a magnetic transducer or by means responsive to the motor's back E.M. F. If the final speed of the motor is to be less than its maximum a non-linear network 14 is connected to by-pass the differentiator 6. This applies a speed responsive signal to the comparator which is greater than the acceleration signal when the speed exceeds a predetermined value. The motor is thus acceleration controlled up to a predetermined speed and thereafter speed controlled; the speed may be varied by controlling the network 14.

Abstract: 1,264,198. Conveyers. A. T. KORNYLAK. 5 Aug., 1969 [15 Aug., 1968], No. 39120/69. Heading B8A. When a shelf 2 is moved to a loading or an unloading station, the edge of the shelf adjacent a transfer conveyer 22 is supported by wedges 90 which engage rollers 21 on the shelf. The shelf includes rollers 12 interconnected by chains and sprockets and the end rollers have gears 20 for engagement with idler gears 44 driven by gears 42 of the conveyer 22. The rollers of this conveyer are also chain-sprocket connected and are driven by a fluid motor 54. In Fig. 4, the conveyer 22, which is movable longitudinally by a fluid motor 82, 86, is shown adjacent a driven loading conveyer 32. In a loading operation, the conveyer 32 is energized to move the load on to the conveyer 22 which is driven until the load is supported thereon. A fluid cylinder 98 is then operated to move the wedges 90 into the position shown in Fig. 2 so that the rollers 21 are engaged and the shelf 2 is supported. The conveyer 22 is then moved towards the shelf by the motor 82, 86 and is supported on the wedges 90 by rollers 140. As shown in Fig. 2, the gear drive between the conveyer 22 and the shelf rollers 12 is now in engagement and, by re-energizing the conveyer 22, the load is transferred to the shelf. To prevent shifting of the load on the: shelf its rollers are locked by a device 142 which engages the gears 20. Manual control is specified but automatic devices may be used. In moving from one end station to another end station, the shelves are pivoted into a vertical position.

Abstract: 1342578 Swaging; stamping BTR INDUSTRIES Ltd 28 Oct 1971 [19 Nov 1970] 55117/70 Headings B3H and B3Q Swaging apparatus comprises a swaging member 30, Fig. 1, consisting of a plurality of radially-disposed swaging fingers 31, Fig. 7, the inner ends 37 of which define a space for receiving a workpiece, resilient means 32 arranged between adjacent fingers, and compression means 11, 25 to force the fingers inwardly against the action of the resilient means and cause the fingers to effect swaging of the workpiece. The main frame 10 of the apparatus has two triangular end plates 11, 12 spaced apart by rods 14, plate 11 having a generally conical, tapered aperture 16 which accommodates end portions 37 in grooves (17), Fig. 2, not shown. A ram head 19 comprises circular plates 24, 25, the latter provided with an aperture 26 and plate 24 connected to an hydraulically-operated piston 40. The fingers 31 are each bonded to, and held spaced from, the next adjacent swaging finger by blocks 32 of elastomeric material. The outer diameter of the ends 37 of the member 30 is such that the member will just enter the apertures 16, 26 with faces 35 fitting in grooves (17), (27), Fig. 5 (not shown). Thus, movement of the piston towards plate 11 causes the fingers to move inwardly and swage a workpiece, whereas movement towards plate 12 allows the blocks 32 to urge the fingers outwardly to release the workpiece. An end stop 39 serves to limit the movement of the ram head so that the degree of swaging of a workpiece may be both repeatable and adjustable. The member 30 is detachable to allow replacement by a member of different diameter for different size work pieces and the rubber blocks may be replaced by thermoplastic material. In a modification the fingers may be held apart by means of spring elements, e.g. spring blades, each blade having one end attached to a finger and the other end attached to the next adjacent finger.
