Abstract: 870,004. Bobbins; winding yarn. CINIGLIO, I. Oct. 15, 1959 [Oct. 17, 1958], No. 34997/59. Classes 120(2) and 120(3) A spool comprises a cylindrical shell which contracts to a predetermined diameter under the pressure of yarn wound thereon and expands to its original diameter on removal of the yarn and is constituted by circumferentially and axially-extending metal or plastic elements guided against one another and normally urged apart by springs interposed between them. As shown, elements 2 have arms 3 engaging in corresponding recesses in elements 1 in which leaf springs 4 are inserted. The elements are secured against relative axial movement by plates 5 affixed to elements 1 and the relative circumferential movements are guided and limited by pin-and-slot connections 6, 7. The spool is assembled for winding by inserting a spindle 8, Fig. 5, into the shell so that the end faces of elements 2 abut lugs 16 and advancing one disc 11 on a driving axle 17, by means of a screw-threaded engagement therewith, so that conical surfaces 10 and 12 on pairs of discs 9 and 11 coact to expand spring wire clips 13 into gripping engagement with the shell.

Title: Improvements in or relating to electro-magnetically actuated clutch driving devices
IPC: F16D27/112
Filed: 1958-11-03
Abstract: 870,823. Feeding record cards. COMPAGNIE DES MACHINES BULL. Nov. 3, 1958 [Nov. 29, 1957], No. 35236/58. Class 106 (1). [Also in Group XXIV] Relates to a construction of a friction disc clutch controlled externally by an electromagnet (see Group XXIV). As applied to the feed mechanism of an accounts machine, an electric motor 128 drives through a gear-train 126, 122 to a first clutch E1 according to the invention, and through a gear train 180 ... 183 to a second clutch E2 rotating in the opposite direction, engagement of either clutch causing a shaft 110 to turn and, through a coupling AC, drive a roller R engaging an accounts sheet B and acting in the manner of a type-writer platen. When the clutches E1, E2 are disengaged, an electromagnetically - controlled brake F is applied to hold the shaft 110 &c. stationary. Control of the clutches and the brake is effected by a three-position switch C fed with current from a source S. On feeding an accounts sheet B into the machine, a conducting mark or line thereon acts through mechanism not described to move the switch C from a position A, where it causes engagement of the brake F to a position M1, thus disengaging the brake F and engaging the clutch E1. Accordingly the shaft 110 and the roller R rotate rapidly to drive the accounts sheet B. When the accounts sheet reaches the end of its travel, another conductive mark thereon causes the switch C to move to the position M2, disengaging the clutch E and instead engaging the clutch E2 to drive the roller R slowly in the opposite direction and feed the accounts sheet B back. When the accounts sheet again reaches the end of its travel, a conductive mark thereon causes the switch C to be moved from the position M2 to the position A, disengaging the clutch E2 and engaging the brake F to station the shaft 110. The accounts sheet B is ejected from the machine on momentary operation of the switch C by hand to the position M2, thus engaging the clutch E2 to drive the roller R. Specification 833,556 is referred to.

Filed: 1965-08-17
Abstract: 1,65,520. Photographic cameras. EASTMAN KODAK CO. Aug. 17, 1965 [Aug. 17, 1964], No.35316/65. Addition to 1, 064, 801. Heading G2A. A camera having a diaphragm vane 22 controlled by a relay 10 operated by a photo-resistor 14 in series with a battery 16 is characterized by a supplementary diaphragm aperture 36 which allows of proper exposure at a predetermined intermediate value of scene brightness in the event of an electrical failure of the controlling electrical circuit. Normally, when depression of a e.g. a shutter releasing member 2 releases the vane 22 to rotate, rotation is stopped by an armature 18 of the relay engaging teeth 20 on the disc when a tapered aperture 26 has exposed the photo-resistor 14 sufficiently to energize the relay. When the circuit fails, the vane 22 rotates until the armature 18 engages a step 34, when the aperture 36 overlies a lens 32. In another embodiment, Figs. 2, 3 (not shown) depression of a member (40) closes the electrical circuit including a solenoid (44) and battery (46). If the circuit is working, the solenoid is urged against the action of a spring into contact with an armature (45). If the circuit is faulty, the spring urges the solenoid into the path of the member (40), which thereby pivots the solenoid and a lever (46a), causing a supplementary vane (54) to partially cover the lens (32).

Abstract: 997,612. Sliding clasp fasteners. H.-U. SOHR. Sept. 6, 1963, No. 35383/63. Heading E2S. A process for the manufacture of sliding clasp fasteners having interlocking wire helices comprises heating wires of thermoplastic material while shaped into helices provided with locking projections to a temperature ensuring their dimensional stability, sewing the helices to stringer tape and then finally heat setting the helices by heating them to a setting temperature which is near the melting temperature of the thermoplastic material comprising the wires. The setting temperature increases the crosssection of the wire and reduces the length so that the sewing threads are tightly engaged, the clearances between the locking projections are also reduced. The heating to setting temperature may be carried out in moist heat, e.g. in a glycerine bath.

Abstract: 1,262,198. Automatic control of rolling. TOKYO SHIBAURA ELECTRIC CO. Ltd. July 15, 1969, No.35548/69. Heading G3R. In a system for automatically eliminating undulations at the edge and centre of strip issuing from a rolling mill, optical detection of the slopes of the undulations at those positions produce electrical signals which are differentially amplified to control the crown of the mill rolls. In Fig.3, photo-electric detectors 11, 12 produce A.C. signals having an amplitude dependent on the maximum slope of any undulation respectively produced at the centre and edge of strip metal issuing from mill rolls 1 the crown of which is controlled by the bending of back-up rolls 10 produced by hydraulic jacks 17 applying forces to bearings 5<SP>1</SP>, 6<SP>1</SP> in opposition but not in line with screwdown forces applied to bearings 5, 6. The signals are rectified at 13, 14 and their difference, derived at 15, adjusts the oil pressure applied to hydraulic jacks 17 in such sense no undulations are produced. Integral or differential components may be added to the control. In one form of optical detector, Fig.6, a beam of light, e.g. a laser, from a source 25 is reflected by the strip 2 and undulations cause an oscillation of the reflected beam over an angle 2# which is dependent on the maximum slope of the undulation. The oscillation is between two photocells S 1 S 2  associated with the input of a differential amplifier (not shown) the output of which is thus independent of brightness and alternates with an amplitude corresponding to the maximum slope of the undulation. Use of a single photo-cell, and use of triangular mirrors or prisms in the path of the reflected light so that two photo-cells may be widely separated, is described.

Abstract: 1284158 Electrodes ZCM CORP 23 July 1970 [4 Aug 1969] 35817/70 Heading A5R [Also in Division H4] A hearing system relies on applying electric pulses to the cochlea, the pulse width varying inversely with the frequency of an audio signal representing sound information and the repetition rate increasing as the amplitude of the audio signal increases. Audio frequency electric signals from a microphone 10 (Fig. 1), after amplification, are applied to three buffer stages 12, 13, 14. Three pulse generators 16, 17, 18 have different thresholds so that soft sounds trigger a single generator, medium sounds trigger two generators and loud sounds trigger three generators. The output pulses are non-coincident. Change in pulse width with frequency is accomplished by inherent operation of the pulse generators 16, 17, 18, the pulse width developed by applying a low frequency sine wave being greater than that developed by a higher frequency sound wave. A stage 24 modulates a R.F. transmitter 26 incorporating an oscillator 28. A coupling transformer 29 has its secondary winding connected to two electrodes 30, in use applied to opposite sides of a person's neck (Fig. 5, not shown). Each electrode may comprise a circular platinum foil (50) Fig. 3 (not shown) forming one end wall of a cylindrical housing (52) and covered with insulation (56). Electrodes for use at microwave frequencies may each comprise an insulated ring (72) Fig. 4 (not shown) and an inner insulated disc, the disc and ring (72) being spaced by two spokes (72). The sheath of a coaxial cable is connected to the ring (72) and the inner conductor is connected to the disc.

Abstract: 1,134,377. Cooling extruded plastics. CROMPTON & KNOWLES CORP. 4 Aug., 1967, No. 35981/67. Heading F4U. [Also in Division B5] Cooling equipment for extruded products, in particular plastics covered conductor wires, comprises a tube 14 attached at one end to extruder head 12 and effectively sealed at its other end 18 by the extrudate c and through which a heat-transfer medium w, e.g. water, flows from inlet 22 to outlet 20. Tube 14 forms part of a closed flow-path comprising a variablecapacity pump 36, a station S essentially comprising temperature sensitive probes 54, 56, and a heat-exchanger 26 where the temperature of medium w is modified by conduction of heat to or from a heat-transfer medium m, e.g. water and/or steam. As shown, water is admitted to chambers 30 of exchanger 26 via conduit 38 and an adjustable flow control valve 50 and steam is likewise admitted via conduit 40 and a second valve 52. In operation, valves 50, 52 are set so that exchanger 26 operates to give the required temperature range between inlet 22 and outlet 20 of water w for the extrudate concerned. If water leaving outlet 20 has a temperature greater than the upper limit of the range, probe 56 acts to close steam valve 52 by passage of suitable expansible liquid therefrom via conduit 60 to a chamber (76), Fig. 3 (not shown) of the valve, increase of pressure in the chamber contracting a diaphragm (70) and moving a valve assembly (66, 68) to close port (64) against the action of spring (84). The required pressure to close the aperture is varied by rotation of a nut (80). At the same time probe 54, Fig. 1, acts similarly on water valve 50 which, although like valve 52 in general construction, has a valve assembly which opens under increasing pressure. If water leaving outlet 20 has a temperature below the lower limit of the range the above procedure is reversed. The temperature range between inlet 22 and outlet 20 is dependent on the adjustment of valves 50, 52 and such adjustment may be so arranged that medium m in exchanger 26 is for the most part either water or steam. Further control is provided by a valve 120 and a by-pass valve 126 which allow division of tube 14 into zones 128, 130, e.g. a substantially constant temperature zone and a varying temperature zone respectively. The extrudate may be of thermosetting and/or thermoplastic plastics. A curing chamber 134 is provided immediately downstream of extrusion head 12.
