Patent GB-1021549-A (GB)
Title: Automatic cop or bobbin feeder
Inventor: OISHI ISAO
IPC: B65H67/08
Filed: 1963-02-25
Abstract: In an automatic cap feeder, wound bobbins loaded in orderly, spaced manner on the lattice bars of a horizontal conveyer pass to a vertically suspended, rubber, separator sheet or curtain which, in cooperation with a mechanical flapper, ensures an orderly arrangement of the bobbins as they roll on to a tiltable shoot plate (the accumulation, and then the absence, of a set weight of a number of bobbins on which arrests the conveyer and then advances it through a distance corresponding to such number of bobbins) whence they transfer to a bobbin elevating conveyer formed with slats each carrying a single bobbin and travelling in unison by intermittent movements at each of which one bobbin is deposited in a supply magazine for feeding an automatic winder which travels around a circular track.  A spare-bobbin box supplies additional bobbins through a swing-plate exit door to ensure that any empty position on the slats becomes occupied. Any unwound yarn end projecting from a bobbin on the slats (and therefore in danger of overlapping adjacent bobbins and thus spoiling the orderly progress of the bobbins and subsequent withdrawal of the yarn end) is cut by a reciprocating knife blade which makes one movement across each slat, Fig. 38 (not shown). The last-wound part of the yarn (usually pulled off manually) is pneumatically and automatically unwound at the elevating conveyer by means of a suction nozzle encompassing the tail end portion of the bobbin (which is then temporarily held stationary) and cut by scissors, Fig. 12 (not shown).  Bobbins deposited in the magazine are conveyed intermittently by magazine cans to yarn withdrawing apparatus comprising a reciprocating searcher mechanism, a rotary, spiral cutter mechanism and a suction nozzle (assisted in its thread withdrawal action by a beater) operating sequentially, Fig. 19 (not shown).

Title: A Camera Shutter having an Electronic Timing Device
IPC: G03B7/083
Filed: 1968-02-16
Abstract: 1,158,691. Camera shutter mechanisms. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. Feb.16, 1968 [April 1, 1967], No. 7621/68. Heading G2A. In a camera having an electronic timing device, the end of the exposure period is determined by the de-energization of an electromagnet which holds the shutter blades open. Since the magnet armature, when released, may take some milliseconds to start closing the shutter, an erroneous extra period t k  is added to the exposure time. This delay is compensated for at the beginning of the exposure period. As shown, a driving disc 3 has linked to it a pawl 4 which causes a shutterdriving ring 5 to execute a reciprocating movement, in known manner, to open and then close the shutter blades 6. In Fig. 1 the disc 3 is shown in the cocked position, being held there by a stop lever 14. On pressing the shutter release 15, a lever 22 is caused to close a switch S 1 , so connecting the magnet 7 into circuit. At the same time, a catch lever 21 disengages from a switch lever 16, allowing the latter to be spring-urged anti-clockwise, so opening a charge-starting switch S 2  and initiating the exposure period determined by the timing circuit Fig. 3 (not shown). Mounted coaxially with lever 16 is a toothed segment 17 engaging with a pinion 18 mounted on a ratchet wheel 19 which co-operates with an escapement member 20. This causes the segment 17 to strike stop lever 14, and disengage it from disc 3, a predetermined time (which can be arranged to be t k ) after switch S 2  has been opened. Thus disc 3 is not released to run down, and so open the shutter, until a period t k  after the timing period set by the circuit has been initiated. Figs. 5 and 6 (not shown) are of a modification in which the delay segment 17 is replaced by a brake lever (25) having an oblique edge which engages with a projection on the shutter-driving ring.

Abstract: 142,255. British Thomson - - Houston Co., (General Electric Co.). March 31, 1919. Transformers.-In electrical apparatus, e.g. transformers, in which the windings 12, 13 are immersed in oil or other cooling and insulating medium, an auxiliary cooling system is set in operation when the temperature of the oil rises above a predetermined value, and maintained in operation until the temperature falls below another predetermined lower value. The auxiliary cooling system comprises coils of pipe 14 surrounding the windings, the pipes being adapted to be traversed by water or other cooling-fluid under the control of a valve 15. The valve 15 is connected by a lever 24 and link 22 to a rocking beam 23, to the ends of which are pivoted the cores 20, 21 of electro-magnets 18, 19. When the temperature of the oil rises above the predetermined maximum, a thermostat 17<1>, in the form of a compound bar, engages a contact 27 and completes the circuit of the electro-magnet 19, which moves the beam 23 to open the valve 15. At the same time, a contact member 30 pivoted about the same point as the beam 23, leaves contacts 29 in the circuit of the electromagnet 19 and engages contacts 28 in the circuit of the electro-magnet 18. A spring 31, connecting the contact member 30 to an arm carried by the beam 23, gives a quick movement to the contact member in either direction. The valve remains open and water continues to circulate through the pipes until the temperature of the oil falls to the predetermined lower value, when another thermostat 17 completes the circuit of the electro-magnet 18 and causes the closing of the valve.
