[Class 45.] A wire or band strap sealing machine is characterized in the provision of a plurality of f independently operable crushing, corrugating, or sealing members each adapted to crush, corrugate, or seal a part of the wire or band or a seal thereon not affected by any of the other members, means being provided to operate these members one after the other. The machine is specially intended for use with seals described in Specification 389,268. As shown, the machine comprises a base a, Fig. 3, adapted to rest on the case to be bound, having an upright back-plate b, bosses b<2> of which form bearings for a shaft c having cams d<1>, e<1>, f<1>, g<1> which, when the shaft c is rotated by a ratchet- and-pawl device (not shown), depress a cutting member d and crushing or corrugating members e, f, g. These members are cut away to house compression springs k and slide in guides h, and their upper ends may be provided with friction-lessening rollers. Housed in bosses b<1> on the plate b is a U-shaped gripping member n held up to cams n<1> by springs n<2>. An anvil a2 on the base a is corrugated at a<2> to conform with corrugations in the seal. In operation the machine is placed in position on the case and a seal such as that referred to above comprising a double-channelled sleeve in one channel of which the end of a wire is secured by corrugation is placed on the case, the free end is passed round the case and inserted in the unoccupied channel, the seal is placed in the machine, the shaft c is turned, so as to depress the member n, which holds the corrugated half of the seal firmly, the free end of the wire is placed in a rocking, slotted tensioning wheel p, Fig. 1, and the shaft c is turned so as to depress successively the members g, d, f, e. The gripping member n, instead of being depressed by the cams n<1>, may have pins u which ride in cam slots t<1> in a horizontally moving plate t. The gripper may be dispensed with entirely, in which case two wire tensioning grips may be used. For the uniting of metal band straps, e.g. hoop iron straps, members w having projections w<1> may be used to produce corrugations x<2> on the flat seal x<1>, or the straps x may be united by punching holes x<3> by means of plungers y, the punched-out parts being turned down to form eyelets.

Abstract: 1,071,067. Superconductor circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 5, 1964 [Aug. 13, 1963], No. 32025/63. Heading H3B. In order to increase the reliability of a thin film cryotron relay device four cryotrons 40, 41, 42, 43 are connected as shown in Fig. 4 so that the control current flows through two paths connected in parallel comprising control conductors 50, 51 and 52, 53 respectively and the gate current flows through two paths in parallel comprising gate conductors 44, 45 and 46, 47 respectively. By connecting the cryotrons in this manner the relay will still operate should any of the gate conductors 44, 45, 46, 47 fail to become resistive or either pair of gate conductors 44, 46 or 45, 47, or should any one or either pair of control conductors 50, 51 and 52, 53 fail by becoming an open circuit, or should any one or either pair of gate conductors 44, 45 and 46, 47 fail to become superconducting. In the arrangement of Figs. 5, 5A (not shown) an electrical conductor is connected between the pairs of control conductors 50, 51 and 52, 53 so that the relay will continue to operate even if control conductors 50 and 53 or 51 and 52 fail at the same time. Similarly a further electrical conductor may be connected between the pairs of gate conductors so that should either pair of gate conductors 44, 47 or 45, 46 fail to become superconducting then a superconducting path will still be available through the remaining two gate conductors and the further electrical conductor. Two further cryotrons may be employed having their control conductors in parallel and their gate conductors in series, the gate conductors being connected between the pairs of series connected gate conductors of the cryotrons of Fig. 4. The parallel connected control conductors may be connected in series with the parallel connected pairs of control conductors of the four main cryotrons, Fig. 6 (not shown), or alternatively each of the control conductors of the two further cryotrons may be connected in series with the series connected control conductors of a pair of the four main cryotrons, Fig. 7 (not shown).

Title: Improved production of carbon tetrachloride
IPC: C07C17/093
Filed: 1937-11-23
Abstract: <PICT:0484888/IV/1> Carbon tetrachloride is produced from carbon disulphide and a sulphur chloride, the reaction being effected, or at least completed, under a pressure of at least 1,5 atmos. and carbon tetrachloride distilled from the product under a similar pressure. The entire reaction and distillation may be carried out at the increased pressure or the principal reaction may proceed to equilibrium at about normal pressure, the product then being distilled at 1,5 atmos. or more causing the initial reaction to go to completion.  Carbon disulphide and excess of sulphur chloride, preferably a 50 per cent excess of the dichloride, are mixed in pump 3 and forced at 1,5-10 atmos. through an iron or steel coil 5 maintained at about 40-150 DEG  C. The product flows to the column 11 of a pressure still 10, the carbon tetrachloride distilled off being condensed in condenser 12.  It may be redistilled over lime or other alkali.  The still residue consisting of sulphur monochloride and sulphur flows to the column 17 of still 16 operated under normal pressure or vacuum.  Sulphur monochloride is condensed in condenser 18 and molten sulphur drawn off at 19.  The former may be chlorinated for re-use.  In an example, the reaction temperature varies from 50 DEG  C. at the start to 70 DEG  C. at the end.  Pressure is from 1,5-2,5 atmos.

Title: Improvements in or relating to interference suppression systems for radio receivers and the like
IPC: H04B1/12
Filed: 1945-11-30
Abstract: 604,719. Preventing inductive disturbance. OXFORD, A. J. H. Nov. 30, 1945, No. 32488. [Class 40 (iv)] [Also in Group XL (c)] In a radio or other telephone channel in which recurrent impulsive interference repeating at a frequency within the audio pass-band is reduced by synchronizing muting, the muting is rendered inaudible by increasing its recurrence frequency to lie outside the pass-band of the channel. A radio receiver subject to interference from radar transmissions is muted in H.F. and L.F. stages by negative impulses derived from the screen 8 of a transition oscillator VI over a phase-reversing valve (not shown). Positive-going locking impulses from the radar transmitter modulator or from an auxiliary receiver are applied to the grid 6 of a synchronizing valve V2. The third grid of the valve V2 is gated by negative-going potentials from the anode of the oscillator V1, being prevented from going positive by means of a blocking condenser C3 and diode V4. Impulses from the anode circuit of the valve V2 are rectified by a diode V3 and applied over a smoothing network R1, C4 as a positive bias to the third grid of the oscillator V1. The oscillator frequency is thereby so controlled by the relative timing of lock and gating impulses as to maintain the timing of the muting impulses to embrace each lock pulse symmetrically with a muting impulse.

Abstract: 211,960. British United Shoe Machinery Co., Ltd., Gouldbourn, J., and Keall, F. B. Nov. 30, 1922. Drawings to Specification. Clutches, claw; gearing for stopping and starting machinery.-The Provisional Specification describes a construction of clutch for an eyeleting machine by which, when a treadle lever is depressed, the main shaft. is rotated through one revolution to set an eyelet. A bolt, carried in a block secured on the shaft, is drawn forward by a spring, when the treadle lever is depressed, to engage one of a series of hardened studs projecting from the base of an annular recess formed in one side of the boss of the driving pulley. As the shaft rotates, a cam-surface on the block trips a spring-pulled catch to bring into operation a brake, a pin on which engages a wedge surface on the block to withdraw the bolt from engagement with the studs, and, with the aid of the brake, stop rotation of the machine. A positive stop is ensured by a shoulder terminating the wedge surface, rebound from which is prevented by a catch plunger in the block. The bolt may be held out of engagement with the studs by a small plunger slidably mounted in the shaft when it is desired to operate the machine by a handwheel on the shaft. Specifications 5397/90, 13541/91, and 8679/07, [Class 43, Fastenings, Dress], are referred to.
