Title: Improvements in centrifuges for separating solids from liquids
IPC: B04B5/00
Filed: 1939-06-23
Abstract: 531,255. Centrifugal separators. SCHULZ, H. June 23, 1939, No. 18315. [Class 23] A centrifugal machine of the kind described in Specification 436,895, for separating solids from liquids, has a rotor 1 which presents a cylindrical surface S to the incoming mixture from the restricted opening 18 at the ends of the radial ducts 16 branching from the inlet 15 and rotating with the rotor 1. The solid matter is deposited on the surface S and the liquid overflows the edge of the annular wall 1a, the discharge pressure from the nozzle 18 being caused by the difference of level of the liquid R in the rotor and of the liquid L in the ducts 16. In the construction shown in Figs. 3, 4 the rotor 1 forms a housing rotating in bearings 2, 3 and having a stationary spindle 5 passing through one end. This spindle is connected by gearing 6, 7, 8, 9, 10 to an internal drum 11 which is caused thereby to rotate slowly on its spindle 13 when the rotor 1 is revolving. The inlet conduit 15 is supported by the shaft 13 and the end of the rotor but it does not rotate. The discharge ends 16 of the conduit are offset from the shaft 13 and have exchangeable nozzles 18 of constricted cross section through which the mixture supplied passes to pockets 19 formed on the inner surface of the drum 11 by radial ribs 19a. The separated liquid overflows the pockets and passes through channels having sieves 27; it then passes through holes 1b in the rotor 1 to a receiver 23b. The solids are deposited in the pockets which are closed at the side by valve flaps 20. During the discharge stage, the securing props 21 are swung towards the axis by pivoted pressers and the flaps are then free to open to permit the discharge of the solids through convergent funnels to fixed receptacles 23a.

Title: Improvements in or relating to machines for pulling-over and lasting the uppers of boots and shoes
IPC: A43D13/00
Filed: 1919-07-29
Abstract: 152,800. Jones, W. H. V. July 29, 1919. Pulling-over.-Apulling-over machine is provided with means for pleating the loose material of the upper and means for stretching a wire or tape round the toe portion, and, preferably, means, for pressing the upper into the feather of the insole, securing the ends of the bracing-wire, and wiping the upper down and around the toe of the last. As shown, the invention is applied to the machine described in Specification 3876/14. The toe pincers 1, 2, Fig. 19, are shaped as shown to pleat the upper. Pleating-fingers 27 are formed on bell-crank levers on the pivots of the toe pincers, the other arm of each bell-crank lever having a slot engaging a fixed pin so that as the pincers 1, 2 move to stretch the upper, the fingers 27 advance to the position shown to pleat it. Between the toe pincers and the side pin-pincers 25 auxiliary pleating and stretching grippers 6, 7 engage the upper, each pair being mounted on a lever 3, Fig. 2, pivoted to a headed pin 21 turning in a bracket 22 on the frame of the side pincers 25. The grippers 6, 7 are first closed and then pulled downwardly by a rod 8 connected to the case of the side pincers 25 so that, after the jaws 6, 7 are closed, they move downwards with the jaws 25. A tooth 17 on the lever 3 engages a spring-pressed rack 14 to hold the grippers 6, 7 in the upper-stretching position, the rack being released by a slide 19 engaged by the jaw 7 when this moves away from the jaw 6 to release the upper. On completion of the stretching operation a binding-wire 42, Fig. 19, is placed in position about the toe of the upper, past the tack throats 50, and its ends secured to hooks 36 on spring-held rods carried by levers 35, Fig. 6, pivoted to a fixed bracket 34 and each provided with a slot 39 engaged by a pin 40 on the side, pincer frames. When these frames move inwards about their trunnions 43 for the overdrawn movement, the levers 35 tighten the wire about the work. As the toe pincers 1, 3 move inwards in this overdraw movement, plates 45, Fig. 19, pivoted to the pincer frame, close inwards in scissor fashion to press the upper into the feather of the insole. The tack-drivers 57, Fig. 8, then move upwards, engaging an incline 58 on a gear segment 53 pivoted at 54, this gear segment rotating a pinion 59 on the tack throat 50. The throat carries a cutter 51, Fig. 9, which, as the throat is rotated, twists the wire about the tack and co-operates with a fixed cutter 52 to sever it. Fixed to the arm 64, Fig. 12. carrying the vamp-presser pad 66, are a number of spring-pressed arms 62 each carrying a roller 63 or equivalent member to wipe over the toe portion of the upper as the arm 64 descends to hold the work. A rounded member 68 carried by a flat spring 67 smooths the upper at the toe. Tape may be substituted for the wine. 42, for binding. Reference has been directed by the Comptroller to Specification 15826/11.

Title: Means for use in continuously flattening tubes of plastic film
IPC: B29C48/90
Filed: 1958-06-13
Abstract: <PICT:0834386/IV (a)/1> The apparatus of the parent Specification (wherein tubular films of thermoplastic organic material are continuously flattened by passing the air-inflated tube through the nip of a pair of rolls) is modified by the provision of two endless belt conveyers each guided to pass through the nip of the rolls for flattening the tubular film and round a portion of the periphery of each such roll, the runs of the belt conveyers that travel towards the nip of the rolls being symmetrical with respect to the axis of extrusion of the film and being adapted to engage diametrically opposite sides of the film and to convey it to and through the nip of the rolls, thereby to flatten the film, and each belt conveyer, after it passes with the flattened film through the nip of the rolls, leaving the flattened film and passing round one of the rolls.  As shown, heated film - forming material is extruded through the annular die 1 of the extrusion head 8 in the form of a tube 2a which is inflated by compressed air introduced through the tube 9 to form a thin-walled continuous tubular film 2 which is drawn by the rotating rolls 3, 4 having resilient sheaths 5, 6 through the calibrating sleeve 10 consisting of wire mesh lined internally with a tubular wick 11 supplied with a liquid coolant such as water.  As the film issues from the sleeve 10, two diametrically opposite sides make contact with the conveyer bands 20, 21 made of synthetic fibres which have been woven into a fabric and rubberized.  The bands pass through the nip of the rolls 3, 4, round the rolls and round the jockey rollers 14, 15 provided with tensioning springs 16, 17 anchored to hooks 18, 19. The modified apparatus prevents the wrinkling of the film while it is being flattened.

Abstract: 1278124 Windscreen wipers K KIRCHNER 14 April 1969 [29 April 1968 13 Aug 1968] 19024/69 Heading A4F [Also in Division H2] An electrically driven windscreen wiper may be operated either continuously or intermittently and when in the intermittent mode the running time or the off time is dependent upon the friction of blade 3 on the screen, as detected by the voltage drop across a resistor 8 in series with the driving motor 2. Thus, in drizzle only one or a few strokes are made at a time. A parking switch 7 ensures completion of a stroke. The voltage on 8 controls the conduction of a transistor 9 in circuit with a timing device which operates an interrupter 13, which may be relay contacts as shown or a further transistor. As shown, the timing device comprises a bi-metal strip 14 which controls an interrupter relay 16. A capacitor 17 ensures that the relay is held closed at least long enough for the parking switch contacts to close. In one alternative embodiment the bi-metal strip is replaced by an electromagnet whose return stroke is restrained by a dashpot Fig. 2 (not shown) and in another the interrupter is opened by a separate motor energized through the control transistor, with a separate, unspecified timer (40) to re-close the interrupter Fig. 3 (not shown). In yet another the transistor controls the current through a hot wire which operates the interrupter directly or indirectly Fig. 4 (not shown) and in a final embodiment the transistor forms part of a low frequency oscillator whose output charges a capacitor which triggers an astable multi-vibrator controlling an interrupter relay Fig. 6 (not shown) and in this case running time is constant but the off time is regulated. In Fig. 7 (not shown) the multi-vibrator of Fig. 6 (not shown) is controlled by a bi-metal device which replaces the low frequency generator. It is asserted that in the bi-metal controlled arrangements the "off" time is dependent upon the motor current, since the bimetal gets hotter while the motor is running and so takes longer to cool.
