Title: Improvements in and relating to bunching mechanism for use on ring or other spinningframes
IPC: D01H1/36
Filed: 1930-08-13
Abstract: 360,086. Bunch-building motion for ring and like spinning-frames. LEES & CO., Ltd. A. and CLEGG, J. W., Soho Iron Works, Oldham. Aug. 13, 1930, No. 24191. [Class 120 (ii).] In ring and like spinning frames wherein a delay or lost-motion mechanism is provided in the heart cam gearing for the purpose of building a bunch prior to the normal building of the cop, a bunch is wound in layers by means of a cam, which is engaged with the building-lever when the relay mechanism is set and is disengaged by the mechanism before the delay is complete, and the heart cam is locked against rotation while the delay mechanism is in operation. As shown, the invention is used with a catch-box delay mechanism as described in Specification 329,432,: [Class 120 (ii), Spinning, twisting, &c.], and a bell-crank lever 5, which is operated to' reset the two parts of the catch-box 6 at the completion of the building of a set, engages an arm 7 on a bracket 9 pivotally mounted on the heart cam shaft and so brings a cam 11 on the bracket into engagement with a bowl 13 on the building-motion lever 14. The cam 11 is driven by gears 10, 12 from a sleeve secured to the boss of the bevel wheel 6a, which normally drives the heart cam shaft through the catch-box after the building of the bunch as described in the prior Specification. A latch 16 holds the bracket down during the building of the bunch and is released, before the delay is complete and normal building commences, by an adjustable stop 18 on the catch-box. The clutch lever 38, 32 of the catch-box, which is operatively connected with the lever 5, carries a stud 31 which, by means of a lever 29, Fig. 4, releases a catch 25 and allows a latch 22 to engage a collar on the heart cam shaft to hold it positively from rotation during the building of the bunch. The latch 22 is operated to release the heart cam shaft by a stop 27 on the catch-box.

Title: Improvements in spinning and twisting machines and the like
IPC: D01H13/18
Filed: 1922-07-25
Abstract: 205,775. Rogers, F. H., (Eclipse Tertile Devices, hic.). July 25, 1922. Delivery, stopping. - In a device for clamping the roving behind the rollers when the roving breaks, a pivoted plate is held in inoperative position by an arm carried bv a lever supported by the roving. When the roving breaks, the arm moves out of the path of the plate and allows it to fall and clamp the roving. The roving passes through a guide 10, Fig. 1, at the end of a counterbalanced lever 21 carrying an arm 26 at the end of which is secured a small cylinder 54 adapted to support the pivoted clamp member 57. When the roving breaks the arm 26 is moved aside by the counterweight 25 and either the vibration of the frame or a cam 60 on the reciprocating guide bar 29. The clamp then falls and its toothed edges 58, Fig. 6, engage the roving over the bar 13. The clamps are arranged in pairs on blochs 56 secured to the bar 13. To re-set the device the clamp plate is pushed back, and as the arm 26 is moved Lack the cylinder 54 engages a pin 59 on the clamp plate and tilts it over into engagement with the end of the cylinder. The lever 21 is jointed at 24 and can be turned up, and the guide 10 is adjustably secured by a sleeve 51. A board 61 hinged on the front of the frame can also be turned up to support a number of levers. The devices can be held against action by locking- devices 65. The arm 26 may be formed as an extension of the lever 21 and be operated positively when freed from the restraint of the roving by a reciprocating cam 60. The outer section of the lever carrying the guide 10 may be pivoted on the bent end 68, Fig. 10, of the lever 21 and be supported in its normal position by a wire 69.

Title: Current discriminator circuit
Inventor: BAILEY ROBERT EDWIN JOHN
IPC: H04Q11/04
Filed: 1963-06-19
Abstract: 1,040,488. Semi-conductor switching circuits. STANDARD TELEPHONES & CABLES Ltd. June 19, 1963, No. 24383/63. Heading H3T. A tunnel diode is connected in parallel with a resistor between the bases of a long tail transistor pair so that the conducting state of the transistors is rapidly reversed if the current through the diodes exceeds a given value. When the current in the highway C-C of a telephone exchange exceeds a given value the tunnel diodes D1, D2 switch to their high resistive state. This renders a transistor T1 conductive so diverting current from T2. The circuit may be used to operate a gate or an indicating device. The resistors R1, R2 by-pass leakage from other semi-conductor circuits so that the circuit will restore when the current being monitored falls below a given value. One tunnel diode may be replaced by a resistor and/or by a normal diode chosen to provide a sufficient voltage across the combination to ensure that the transistors switch, as illustrated in Figs. 1 and 2, not shown, which relate to circuits using single transistors, not in accordance with the invention. If the tunnel diodes are reversed the direction of current flow in C-C and from VB may be reversed (Fig. 3, not shown).

Title: Data communication apparatus
IPC: G06F13/22
Filed: 1966-06-01
Abstract: 1,091,730. Input/output control. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 1, 1966 [June 29, 1965], No. 24416/66. Heading G4A. In data communication apparatus, data sampled from cyclically scanned input lines is stored, and in response to a control signal, stored samples from only predetermined priority ones of said lines are transferred to an output during at least one scan cycle. A number of input lines are scanned sequentially, a sample from each being stored in a control word respective to the line in a recirculating delay-line store which recirculates say eleven times while a given line is being sampled once. Each control word comprises a buffer field from which a complete data character can be gated in parallel to a data processing system, an adjacent field receiving the samples and feeding the buffer field, a bit indicating if the buffer field is ready for gating out, a " priority service " bit indicating if an unsuccessful attempt was made to gate the buffer field out, a count field incremented by one each cycle of the store and indicating the point in time when the input line should be sampled, and error, status and command (transmit or receive &c.) fields. An oscillator-driven ring provides timing pulses and drives a binary counter the count of which specifies the identity of the input line currently being scanned. This count is gated to the data processing system with the control word buffer field, and is also decoded to feed an OR gate via a plugboard. The plugboard enables any input lines to be specified as priority lines. The OR gate output partially controls the setting and resetting of " priority service " bits as appropriate. A cyclic pulse generator produces pulses with a separation equal to the repetition interval of the fastest input line minus the time required to service all priority lines, and each of these pulses causes a priority cycle during which only stored characters relating to priority lines can be gated to the data processing system, and these only if said system permits. When such a character is gated, the " priority service " bit corresponding to it is reset. If any " priority service " bit remains set at the end of the cycle, further priority cycles are taken until none remains set. Successive such cycles are delineated by successive appearances of a reference control word at the read/write position of the delay-line store. A core store may replace the delay-line store. The cyclic pulse generator may be a (single-shot) multivibrator, or a field in the delay-line store stepped by one each cycle of the delay-line, or a separate binary counter. Modifications appropriate if a priority cycle is to be initiated merely following failure to service a priority line, and if two or more consecutive priority cycles are never required, are described.

Title: Process of perfluoroalkylating aromatic compounds
IPC: C09B47/14
Filed: 1956-08-10
Abstract: Alkyd-type resins, which are both oleophobic and hydrophobic, are prepared from perfluoroalkylated phthalic anhydrides in which the perfluoroalkyl group contains 3-12 carbon atoms.  In an example, perfluoroheptylphthalic anhydride and glycerol are heated together in the molar ratio 3:2, and a solution of the product in a fluorine-containing solvent is coated on glass to give a film which hardens on heating.ALSO:The invention comprises perfluoroalkylated aromatic compounds and a process of preparing them by the action of a perfluoroalkyl monoiodide having 3-12 carbon atoms in the molecule on an aromatic compound having a replaceable nuclear hydrogen atom, at 200-350 DEG  C.  In examples benzene is heated with perfluoropropyl-iodide, and perfluoroheptyl-iodide, to give perfluoropropyl or perfluoroheptyl benzene with some diperfluoro-derivatives and isomeric products; toluene, naphthalene, benzonitrile, bromobenzene, iodobenzene, and phthalic anhydride, are also treated with perfluoroheptyl iodide to give the corresponding perfluoroheptyl products.ALSO:The invention comprises aromatic dyes containing nuclear-attached perfluoroalkyl chains of 3-12 carbon atoms, which are soluble in fluorinated solvents but insoluble in hydrocarbon solvents, and which contain at least about 50% chlorine and are stable at temperatures at least as high as 200 DEG C., and a process for perfluoroalkylating aromatic dyes, containing a replaceable hydrogen atom attached to an aromatic nucleus, by reacting them with a perfluoroalkyl monoiodide having 3-12 carbon atoms in the molecule at about 200-350 DEG C.  Examples describe the action of perfluoroheptyl iodide on copper phthalocyanine, thioindigo, pyranthrone, niolanthrone and dichloroisoviolanthrone. Alternatively dye intermediates may be perfluoroalkylated before conversion into dyes.  The products may be used for colouring polytetrafluoroethylene.  Thus a film of "Teflon" (Registered Trade Mark) may be dyed or printed with a solution of the dye in a fluorinated solvent and then heated to its transition temperature (324 DEG C.) to enable it to absorb the dye.  Alternatively printing may be affected with heated type, maintained at about 350 DEG C., on a "Teflon" film uniformly coated with the dye (the unabsorbed portions of which are subsequently dissolved off) or having a thin sheet material coated with the dye interposed between it and the heated type, the pressure of which causes the dye to migrate into the film.

Title: Improvements in or relating to dielectric heating apparatus for the high frequency heating of dielectric material
IPC: H05B6/62
Filed: 1945-09-26
Abstract: 599,529. Dielectric heating. WEST INGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 26, 1945, No. 24965. Convention date, Sept. 28, 1944. [Class 39 (iii)] [Also in Group XL] A high-frequency dielectric heating apparatus energized at a frequency giving rise to standing voltage wave patterns on the electrodes 6, 10, comprises a generator 1 connected to one end of the electrodes by a transmission line 4, 8 and a resonant chamber 22 connected to the other end of the electrodes by a transmission line 16. The resonant chamber comprises an outer closed cylinder 20 containing an inner concentric closed cylinder 30 with an eccentrically mounted disc 38 driven by an electric motor 34. Rotation of the disc 38 causes variations of capacity within the chamber to vary the tuning either side of the resonant frequency thus causing the standing voltage wave pattern to migrate regularly over the heating electrodes. The variations of capacity caused by the movement of disc 38 are such that the standing wave pattern is shifted sufficiently to cause the maximum and minimum valves of voltage to appear temporarily at every point of the electrodes, and thus ensure uniform heating of the dielectric material.

Abstract: 733,312. Radiolocation; automatic gain control. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 6, 1952 [Oct. 9, 1951], No. 24978/52. Classes 40 (5) and 40 (7). In a radar apparatus, the gain of an intermediate-frequency amplifier 9 in the receiver channel is reduced at each transmitting pulse and gradually increased under the control of a sawtooth voltage pulse derived from a resistance network 32 connected in the discharge path of a condenser 25 which is discharged by a gas-discharge tube 23 triggered by the synchronizing pulses. Potentiometer 36 controls the amplitude of the sawtooth voltage pulse resistor 33 controls the duration independently by varying the time constant of the discharge circuit. In Fig. 1, curve a represents the synchronizing pulse supplied to the grid of tube 23 from synchronizing source 17, and curves b to e the sawtooth voltage pulse for various states of adjustment of controls 33 and 36. In order to ensure that the intermediate-frequency amplifier is cut off during the transmitting pulse even when potentimeter 36 is set to produce the minimum amplitude of sawtooth, a peaking condenser 39 is shunted across resistor 35 and potentiometer 36 and introduces a spike s into the waveform. The resistance of network 32 may be made sufficiently low to permit connection with a cable 21 without employing the impedance-matching devices.
