Title: Improvements in or relating to driving mechanisms for winding-up machines
IPC: D06B3/32
Filed: 1954-05-11
Abstract: 778,668. Variable speed driving mechanism. NIELSEN, H. B. May 11, 1954 [May 12, 1953], No. 13784/54. Class 120 (2). [Also in Groups XVI and XXIV] A driving mechanism for winding machines of the kind in which a band-shaped or threadshaped material is wound from one or more feed rollers on one or more winding-up rollers, comprises a pair of overlapping discs rotatable about parallel axes, one of the discs 1 being connected to drive the feed roller or rollers and the other of said discs 2 being connected to drive the winding roller or rollers, and a friction roller 4 driving both the discs and mounted therebetween with its axis normally contained in the plane of the axes of the discs and extending at right angles to the axes of the discs and so as to be capable of movement along its axis and substantially at right angles to its axis in a direction parallel to the discs under the action of a force which decreases when the roller moves in the direction of the force and increases when the roller moves in the opposite direction. As shown, chrome steel discs 1 and 2 are rotatable about their axes, the disc 1 having a shaft connected by gearing to a winding roller (not shown), the disc 2 being similarly connected to an unwinding shaft (not shown). Both discs engage a friction roller 4 slidable along and rotatable on a shaft 5 supported in a bearing 6, the shaft 5 being driven by a motor, not shown, in the direction 9 to rotate the discs 1, 2 in the directions 10, 11 respectively. An increase in diameter of material on the winding roller causes an increase in tension of the material being wound, thereby causing the roller to move downwardly against a spring 7 to alter the drive ratio between the discs 1, 2 and roller 4 by movement, to the left, of the roller 4 along its shaft 5 to reduce the speed of the winding roller. Similarly, a reduction in tension causes an increase in speed of the winding roller by movement to the right of the roller along its shaft 5. The tension of the spring 7 is adjustable such that the tension of the material may be varied. In a modification, the shaft carrying the friction roller may be movable as a whole at right angles to its longitudinal direction instead of being rotatable about the bearing 6 and the spring 7 may be replaced by electromagnetic, pneumatic or hydraulic means.

Abstract: 1,029,052. Pilot controlled A.G.C. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 8, 1963 [April 11, 1962], No. 13890/63. Heading H4R. In a carrier wave telephony system a pilotcontrolled gain arrangement comprises a signal amplifier having a gain controlling negative feedback circuit including a thermistor the current through which is derived from the pilot signal at the output of the signal amplifier. Fig. 1 shows a signal amplifier 2 from the output of which the pilot signal is extracted by filter 3 and applied via amplifier 4 to a rectifier 5, the resulting D.C. signal is amplified in amplifier 8 in whose output circuit is connected the thermistor 7 the impedance of which is reflected, via transformer 17, into the gain controlling feedback circuit 6 of amplifier 2. The D.C. amplifier 8 has negative feedback from the output circuit to the input via resistors 21 and 22, this arrangement giving a lower gain to rapid changes of pilot signal in amplifier 8 due to the thermal inertia of the thermistor.

Title: Apparatus for registering binary code combinations

Filed: 1963-04-11
Abstract: 963,674. Computing check symbols. TELETYPE CORPORATION. April 11, 1963 [April 25, 1962], No. 14511/63. Heading G4A. Data words from a tape reader are fed one bit to each of a number of modulus two adders in parallel where each bit is added to the total, accumulated on the previous addition in the adder one cycle step to the right, so that each bit of the final total forms a spiral parity bit for the group of words. As described capacitors 46-50 are each either charged or uncharged according to a modulus two total so far accumulated. A relay 22 is closed, shifting contacts 41-45 to connect with leads 40. Each capacitor thus sets a relay 31-35, corresponding to the capacitor cyclically to the right, so that the relay is either energized or deenergized, according to whether the setting capacitor is charged or uncharged, e.g. relay 32 corresponding to capacitor 47 is set according to capacitor 46. The energized relays have their holding contacts 52 closed and their contactors 30 against a contact M. Contactors 11-15 of a tape reader 10 are set to the next word to be added, e.g. contactor 11 represents one if it engages contact M to indicate a hole in that tape position, while if it engages contact S it represents a zero. Each contactor 30 comprises with its corresponding contactor 11-15, and lines such as 24a, 24b, an "exclusive or" gate; thus if, for example, contactor 30 associated with relay 31 and contactor 11 are set to like condition, ground 36 is connected to capacitor 46 thus setting it to zero, while if the settings are opposite a positive source 17 is allowed to charge the capacitor 46 setting it to the "one" state. Thus the capacitors 46-50 are set to give the result of a modulus two addition of the previous total given by the setting of the contactors 30 and the new word in the tape reader. The cycle is then repeated. Further contactors 56 close when relays 31-35 are energized to connect positive outputs 60 to a distributer according to the final total. Plug and socket connections 40 allow the number of steps of the shift to be varied, or switches may be provided so that a straight parity check may be brought into operation when required.

Abstract: 221,013. Ollard, E. A., Robinson, E. Y., and Metropolitan-Vickers Electrical Co., Ltd. June 2, 1923. Metals, depositing; moulds; preparing surfaces; treating after electrolysis; electrolytes, agitating. -Metallic parts of envelopes of thermionic valves and the like are produced wholly or mainly by electrodeposition. A copper tube closed at one end may be deposited on a mandrel or former which is preferably rotated at a surface velocity of 1000 ft. per minute while acted on by a jet of electrolyte. The mandrel may be of bronze, or of steel copper-plated in a cyanide bath. Before deposition of the tube, the mandrel may be dipped in potassium sulphide solution, or in a fusible material such as Wood's metal or wax-graphite mixture, to facilitate removal of the deposit. The mandrel may be slightly conical, and the deposit may be loosened by spinning. A feather edge may be given to the copper tube by raising the mandrel at intervals from the depositing bath. The open end of the copper tube may be enlarged or flared. Further copper may be deposited on the tube after attachment to the glass portion of the envelope. In another method, the end of the glass portion is first gilded, for instance by repeatedly dipping in gold chloride solution and heating, or by rolling in gold leaf, the gold being then fused into the glass. A wax or fusible metal former is then secured to the glass and the copper tube electrodeposited on the former and over the gold. Subsequent heating causes alloying of the gold and attachment of the copper and glass. Further copper may be electrodeposited after this operation. A modification consists in electrodepositing a band of copper 18 on the gold and uniting it with the glass. The tube 1 is then formed by electrodeposition, after attaching either a fusible mould or a thin copper tube, which may have been electrodeposited, and preferably is sprung partly over the copper band. This thin tube may be stiffened by filling it with fusible material.
