Title: Improvements in or relating to printing telegraph apparatus
IPC: H03M13/51
Filed: 1938-06-01
Abstract: 514,588. Type-printing telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 1, 1938, No. 16445. Convention date, June 10, 1937. [Class 40 (iii)] In a printing telegraph system for receiving signals having an invariable number of marking elements differently disposed with respect to spacing elements, an error indicating device is operated if the number of marking elements received is not correct. Signals received from line L by a polarised relay 15 cause positive or negative polarity to be impressed in succession on the segments 1 to 7 of a distributor 18 to which segments are connected individual relays 8 to 14. Only marking elements operate these relays which, when actuated, lock up and close contacts 20 to pass current through impedances R1 to R7 to three relays 21. 22, 23 in series. Assuming the correct number of marking elements to be three, relay 21 is adjusted to be actuated by the current passed by three or more of the relays 8 to 14, relay 22 is responsive to the operation of four or more, and relay 23 is responsive to one or more. The relays 21, 22 and 23 are connected as shown to a resistance and battery 27 and an indicating device 26. If the number of received marking impulses is other than three, a circuit is completed through the device 26 allowing a bar 29 to fall to cause an error indication to be printed. As the relay 23 is always operated by one or more marking impulses it may alternatively be inserted at the point 32. The magnets 8 to 14 may be used to actuate selector bars for type selection. Specification 480,150 is referred to.

Patent GB-1004367-A (GB)
Title: Improvements in and relating to machines for finishing gear wheels
IPC: B23F19/06
Filed: 1964-04-22
Abstract: 1,004,367. Bearings. F. HURTH and H. HURTH. April 22, 1964 [June 10, 1963], No. 16629/64. Heading F2A. [Also in Division B3] A gear-finishing machine comprises a rotary tool 15, a tool- or work-slide 19 which can be fed against a fixed or movable stop 27, and switch means associated with the stop and responsive to thrust. The work-gear 26 is carried by stocks which may be adjustably mounted. The slide 19 is moved upwardly, by springs 38 or fluidpressure means, as limited by the cam 27 on a shaft 28 which also carries switch-controlling cams 33, 34. One end of the shaft 28 is carried in a bearing 303, Fig. 3, in a box 302 which is mounted by a wedge or balls 304 in the machine frame 10. When a load occurs on the roller 27, a magneto-elastic cell 305 undergoes compression causing a change in inductance to operate a pulse-generator 312 when a difference voltage exist between rectifier bridges 321, 322. A variable resistor 316 controls the sensitivity of the circuit and a heating device 310 compensates for temperature fluctuations. In operation, the work feed is commenced, the tool is rotated, and the cam 27 is rotated. The cam 27 reaches the point at which maximum feed of the work is permitted, before the gearfinishing operation is complete. The cam is therefore stopped until the roller 37 is able to contact it again. During this time, latches 302A, preventing movement of the block 302, are released and the electrical circuit is closed by a switch 322. As soon as the pressure between the roller 37 and the cam 27 is sufficient, the generator 312 produces a pulse, the cam is re-started and the work, after a short dwell, is withdrawn first slowly and then rapidly. Fluid-pressure devices or other types of electric switches may be used to sense the pressures. Specifications 991,194 and 991,195 are referred to.

An escapement arranged in a casing between a continuously replenishable energy storage means 12, Fig. 1, and a driven member 19 to be moved impulsively and stepwise thereby, comprises an eccentric cam 28, Fig. 2, arranged to be moved continuously by a drive motor 1 for replenishing the energy storage means, the cam engaging an arrester member in the form of a carriage 17<SP>1</SP> to move it back and forth between stops 25 anchored to the casing, the carriage 17<SP>1</SP> having projections 17, 18 to engage guides 35, 36 on the driven member, and the guides being staggered with respect to each other by at least the width of one projection so that the projections on movement of the carriage spring from one guide to another and so allow of stepwise impulsive movement of the driven member. The latter has pins 22, Fig. 8, to engage teeth 23 on a cam plate 24 for actuating levers of a mechanism to be controlled. The means 12 consists of a strip tension spring which is continuously wound through a gear train 4 ... 11 from the motor 1 and urges shoulders 42, 47 at the ends of the guides 35, 36 into engagement with the projections 17, 15 until released by movement of the carriage. The cam 28 engages the sides of a rectangular recess 30 in the carriage, but may be shaped as shown in Fig. 3 to co -operate with lugs 43, 44 the position of which in the recess 30 determines the travel of the carriage. Fig. 4 shows a further construction of guides and projections in which edges 61 are equidistant from the shaft of the driving member so that the latter is subjected only to a pure turning movement when released by the projections. To reduce shock between the carriage and driving member, the guides have a varying radius to cause a slight displacement of the carriage during each step:

Abstract: 667,034. Artificial fishing flies. ISAKSSON, G. L., and ISAKSSON, V. June 27, 1949, No. 17000/49. Class 48. Artificial objects such as flies for fishing or articles for decoration are made by winding in partly overlapping or abutting manner a narrow strip 3 of elastic or tensile water-resistant synthetic material which is transparent and / or coloured and/or patterned on to a core such as the shank of a fishing hook 1, the number of turns being varied to build up the various portions of the body and the tensioning of the strip at winding being varied to obtain the different colour, markings or transparency of these various body portions. Two or more strips of different colour, length and width may be wound on the same core, one beneath the other. The body may be given a segmental appearance, Fig. 16a, by twisting the strip 3 into tubular form or folding it lengthwise and then winding it in spaced turns on the hook, a second layer then being formed by windings of plain i.e. untwisted or unfolded strip ; alternatively a thick transparent or coloured thread may be placed under the strip and both wound on together. To simulate hairs on the fly, fibres of silk, wool, hair or feather are glued to the strip before winding so as to project rearwardty from the edge of the strip. Wings are secured by means of the winding strip or a thread and at the point of attachment the wing is folded double longitudinally to simulate a natural wing attitude. A layer of metal or of pulverulent dye may be placed under the last layer formed by the strip. The strips may be wound on a core preformed to the approximate shape of the body and placed directly on the hook shank. The core may be formed by winding a rectangular or triangular sheet of plastic material on to the shank 1, Fig. 21, and then winding on tightly a thread 17. In order to provide a core that is longer than the shank of the hook a nylon thread is secured to the hook and tensioned so as to extend along and beyond the shank; the strip is wound on the shank and continued rearwardly beyond the bend in the shank on the nylon thread.
