Filed: 1953-11-24
Abstract: 737,542. Electric thermometers. GENERAL ELECTRIC CO. Nov. 24,1953 [Nov. 26, 1952], No. 32589/53. Class 40 (1). An electric resistance thermometer comprising a coil of tungsten wire 4 wound on a grooved insulating former 5 and supported centrally inside a metal tube 1 with a packing of magnesia powder 15, has its thermal conductivity improved by replacing the air in the voids inside the tube with a stable, inert monatomic gas, e.g. helium. The residual air in the tube is withdrawn through a glass tube 17 before the gas is added, and the tube 1 is completely sealed, the leads being taken to terminals 9 via glass-metal seals 16 mounted on a plate 11 which is itself sealed to the metal head 2 of the unit. The gas must be non-corroding, have high stability at high temperature, and should not support combustion or diffuse through the walls of the tube, and have good thermal conductivity.

IPC: B21B43/00
Filed: 1966-07-20
Abstract: 1,182,777. Rolling. DAVY & UNITED ENG. CO. Ltd. 20 July, 1967 [20 July, 1966], No. 32631/66. Heading B3M. Apparatus for transferring rolled products such as bars, plates, or sections to or from a cyclically movable bed is arranged to transfer a group of products during each cycle of the bed. When, for example, a group of six small sections are delivered to a run-out table during one cycle of an adjacent cooling bed, the apparatus transfers the products to the bed in six movements with a transfer stroke which progressively decreases, such that the products are spaced across part of the bed. In one form, Fig. 1, the apparatus includes a number of ducking dog units 2 which each roll along guides 1 under the action of an operating rod 3 which is pivoted at its base to a fixed support. Each unit includes a dog 7 which, when moved to the left, ducks under a rolled product supported on run-out table rollers 36, and when moved to the right, shifts the product to a cooling bed. The rod 3 is pivoted by a piston-rod 18 which reciprocates in a cylinder 20. To vary the stroke of the unit the cylinder is pivoted about a shaft 5 to alter the position of the end 16 of the piston-rod within a slot 15 in the rod 3. When the cylinder has been pivoted in a number of steps corresponding to the number of products in a group it is immediately reset to its starting position. In an alternative form, Fig. 4, the stroke is altered by changing the axial position of the cylinder 20, this being effected by rotating eccentrics 33, which co-operate with supports 32 of the cylinder, about a fixed shaft 35.

IPC: H04L27/12
Filed: 1967-07-19
Abstract: 1,210,816. Digital transmission systems. MARCONI CO. Ltd. 5 April, 1968 [19 July, 1967], No. 33136/67. Heading H4P. Frequency shift binary signals are derived from a square wave clock pulse generator having a frequency very much higher than that of the frequency shift signals. The clock pulses are divided to provide a number of further clock pulses, all at different frequencies. Under the control of input binary data different combinations of the further clock pulses are combined to form one or other of a pair of waveforms which are fed to a divider, the divider giving the required shift signal without phase or amplitude discontinuity. Any of a number of pairs of frequencies may be selected, each pair has a common centre frequency. In one embodiment, Fig. 1, binary input signals at K energize mark and space leads M and S which feed a combiner C containing a number of switches CS, CM which are set according to the required pair of output frequencies. Combiner C controls gates in a divider unit B. Unit B is fed by the high frequency clock A, and includes dividers BD, so generating seven different further clock pulse signals. Under control of combiner C selected clock signals are gated together to give an output at gate BN which is fed to divider E. This has a large division ratio and so the output signal has no amplitude or phase discontinuities. In further embodiments, Figs. 3 and 5 (not shown), the output signal returns briefly to a datum frequency intermediate the mark and space frequencies whenever there is a transition from mark to space or vice versa.

Title: Improvements relating to repeaters in electrical communication systems
IPC: H04B3/20
Filed: 1945-12-07
Abstract: 604,887. Two-way transmission. SIEMENS BROS. & CO., Ltd., and REED, M. Dec. 7, 1945, No. 33199. [Class 40 (iv)] A two-way repeater comprising go and return amplifiers rendered operative alternately at a high-frequency, provides an output signal from each amplifier in the form of substantially vertical-sided pulses, amplitude modulated in accordance with the incoming signals. The system is particularly applicable to carrier current working and the equipment comprises a west-east amplifier P, an identical east-west amplifier Q and a pulse generator G whose output has a frequency at least twice the highest frequency component to be transmitted. The generator G consists of two valves VAG, VBG connected as a multivibrator and the output of VAG is passed through a transitron VCG so as to produce vertical-sided positive pulses while the output of VBG is similarly passed to VDG. Amplifier P has two input valves VAP, VBP, connected in push-pull, and an output valve VCP, all of which are normally cut off by the negative voltage built up on their suppressor grids. Each positive pulse received over wire GWP renders the valves conducting by raising the potential of the suppressor grids and the amplitude of the corresponding anode pulse passed by the valves VAP, VBP is determined by the incoming signal voltage received over line TCW through network FNW. The output of the first stage is passed through a low-pass filter FP which restores the waveform to that of the incoming signal and this is applied to the control grid of VCP, the output of which consists of amplitude modulated pulses of anode current. The final output passes through a filter FNE to line TCE. Both filters FNE, FNW are identical and are of a constant resistance low-pass type; they prevent the passage of the high-frequency components to the line and pass an output similar in form to the input. The voltage changes produced in the output of one amplifier have no effect on the input of the other since they occur while the latter is suppressed and are negative.

Abstract: 656,046. Control of A.C. motors. BROOKHIRST SWITCHGEAR, Ltd., and SHREEVE, A. G. Dec. 25, 1948, No. 33330. [Class 38(iii)] A polyphase alternating-current motor is combined with means for switching the supply to the motor from alternating to direct-current, and switch means are provided which effect a step-by-step change in the direct-circuit connections. to the phases of the motor so as to cause an angular movement of the magnetic field resulting from the direct-current supply. The switch means may be of the rotary type and hand or motor-operated. As shown, a threephase squirrel-cage motor M drives the table of a boring machine and is provided with forward contactor FC, reverse contactor RC, and inching contactor IC. An inching switch 14, which is driven by pilot motor 15, controls the supply, through transformer 16 and rectifier 17, of directcurrent to the induction motor. Control switch 10 is operated by a lever movable in a slotted gate, Fig. 2 (not shown). In the " off " position of a selector switch 11 contacts 23, 24, are closed so that appropriate movement of the control switch 10 closes contacts 18, 19, or 18, 20, to energize contactor FC or RC. To stop the machine, the switch 10 is positioned to de-energize the main contactor, open switch 22, and close switch 21, whereupon the coritactor IC is closed and the induction motor is dynamically braked. When the switch 11 is moved to close contacts 28, 29-20 , 26, and the member 10 is actuated to open switch 22 and close switch 21, the coil 31 of a timedelay 30 is energized, so completing a circuit to the motor 15. The rotation of switch 14 energizes the stator windings of the motor M from the direct-current supply in such manner that a slowly rotating field is developed for low-speed operation of the induction motor. If the selector switch 11 is positioned so that only contacts 25, 26 are closed, step-by-step movement of the induction motor is obtained by repeated alternate actuation of switches 21, 22, the timedelay relay 30 being closed, when energized, for a period sufficient to allow a small movement of motor 15 and changeover of switch 14. Reverse operation of motor 15 is provided by positioning the switch 11 to close contacts 25, 27. A lamp may indicate the energization of contactor IC. The switch 14 may be of the type described in Specification 600,344. The Provisional Specification refers to the replacement of the rotary inching switch by a series of contractors acting in a predetermined sequence.
