Patent GB-832076-A (GB)
Title: Improvements in or relating to the sterilization and subsequent protection of articles
IPC: A23L3/00
Filed: 1956-10-30
Abstract: Foodstuffs, medical instruments, &c., to be sterilized are heated in a heat-sealed container of flexible sheet or film polymer plastic which has been subjected to the action of X-rays, gamma rays or high-energy electrons of a dosage producing sufficient cross-linking to enable the polymer to withstand the sterilizing temperature whilst leaving sufficient soluble fraction in the polymer to enable the heat seal to be made.  The preferred polymer plastic is polyethylene irradiated to between 5 and 12 megarads.  During the sterilizing operation, which may e.g. be effected by heating to 100-150 DEG  C. for from one to sixty minutes, the heat seal may be kept secured mechanically, or the polymer plastic may be prestressed before irradiation, allowing it to contract on to the protected article during sterilization. According to an example, an egg was broken into a bag formed from polyethylene sheet previously subjected to a radiation dose of 6.8 megarads of gamma radiation.  The bag was sealed with a hot iron which was then used to fry the egg in its bag. The following Specifications giving details of the effects of exposing polymer plastics to radiation are referred to: 732,047, 739,709, 740,899, 741,826, 742,933, 747,474, 747,478, 749,680, 759,702, 761,051 and 761,766.

Title: Improvements in or relating to pulse generating circuits
IPC: H03K4/00
Filed: 1953-11-30
Abstract: 741,407. Pulse-shaping circuits. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. Nov. 30, 1953 [Nov. 29, 1952], No. 33129/53. Class 40 (6). A circuit for generating from a rectangular pulse a pulse having sides which slope in opposite directions comprises a storage circuit the charge of which is changed upon the occurrence of the leading edge of the rectangular pulse and is changed in the opposite direction upon the occurrence of the trailing edge of the pulse, both changes being terminated after a predetermined period. The Figure shows a circuit for converting a rectangular pulse applied at input 1 into a trapezoidal pulse at output 10. Diodes 3 and 4 are normally conducting and capacitors 5 and 6 remain uncharged until a positive pulse is applied at input 1 when on occurrence of its leading edge diode 3 is cut-off and capacitors 5 and 6 commence to charge towards the voltage +V1 until the peak voltage of the input pulse is reached when diode 3 conducts and the charging ceases. The charges on capacitors 5 and 6 are held until the trailing edge of the input pulse occurs when diode 3 is rendered conducting and capacitor 5 immediately discharges via diode 3 and resistor 7 and capacitor 6 discharges via resistor 9 until earth potential is reached when diode 4 becomes conducting. A trapezoidal pulse, Fig. 2 (not shown), is thus generated at output 10. If the period during which the capacitors are charged is made equal to the duration of the input pulse a triangular pulse is generated, Fig. 3 (not shown).

Abstract: 861,139. Gating circuits. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Oct. 24, 1957 [Nov. 23, 1956], No. 33238/57. Class 40 (6). A gating circuit comprises a rectifier which is controlled by the firing of a gas-discharge tube having three or more electrodes and which is itself fired by the application of voltages to at least two of its electrodes. The Figure shows a gating circuit for controlling the flow of an alternating current between input point A and output point B in dependence upon the firing of a thyratron tube T. The voltage - V normally biases rectifier D to a non-conducting condition so that the gate is closed. When a bias +V is applied to the anode of tube T and bias +U is applied to the auxiliary electrode H the thyratron T fires and the current flowthrough diode D and inductor L causes diode D to conduct so that the gate is opened to transmit the alternating signal from point A to point B. In order subsequently to close the gate the gas tube T is rendered non-conducting by suppressing the anode voltage +V. The inductor S prevents the input signal being shunted across tube T.

Title: Electromagnetic flowmeter characterised by zero quadrature signal
IPC: G01F1/60
Filed: 1976-08-11
Abstract: 1515207 Electromagnetic flowmeters SYBRON CORP 11 Aug 1976 [14 Aug 1975] 33476/76 Heading G1N [Also in Division H2]  In an electromagnetic the current applied to the field coils has a waveform in the form of a series of alternating sinusoidal segments of a sine-wave, each segment being of one half cycle duration and ter-  minating with a zero slope, and a series of alternating flat segments, one flat segment being interposed between each of the sinusoidal segments. The waveform may be synthesized by the circuit of Fig. 3 in which a sinusoidal voltage 42 is developed across resistor 44 from source 46 and used to charge capacitor 48. As the voltage 42 passes positively through zero and with electro-mechanical switches 52A closed and 52B open capacitor 48 is charged through diode 50a to the positive peak voltage. The voltages across resistor 44 and capacitor 48 are connected to respective inputs of  differential amplifier 56 so that when the difference voltage 58 reaches zero the differential amplifier releases relay 54 so that switch 52A opens and 52B closes. The voltage 30 across 48 then follows the negative slope of voltage 42 until it reaches the negative peak voltage. This voltage is held until the output 58 of the amplifier 56 is again zero and the switches change over. The output of the synthesizer is converted to a current waveform of the same shape by amplifier 34 and fed to the coils of the flowmeter, Fig. 1 (not shown) to produce a corresponding magnetic field across the flowmeter tube. The resultant electrical signal induced by the flowing fluid in the tube is picked up by a pair of electrodes and fed to a gated sample and hold circuit having an output connected to a gated D.C. amplifier. The gating signal 60 is obtained from comparator 59 which generates the signal 60 when the voltage from differential amplifier 56 exceeds the threshold voltages of Zeners 64A, 64B. Thus the flowmeter output signal is only derived during the time that a D.C. magnetic field is applied to the fluid and polarization problems are avoided by alternating this D.C. field.

Title: Pressure medium operated drive system for operating a windscreen wiper
IPC: B60S1/10
Filed: 1975-08-12
Abstract: The drive is effected by means of a piston motor. In order to relieve the piston (2) of load in the parked position and to permit direct manual activation in the event of damage, a shut-off valve (5) is provided. Thus, when switching off the drive it is ensured that the piston (2) will come to a stop in a predetermined limit position without, however, loading the piston (2) with compressed air. The piston (2) is acted on alternate sides by means of a change-over valve (3). The latter is actuated by means of control pulses which are triggered by the moved piston (2) in the working cylinder (1). The shut-off valve (5) is switched by means of a manually actuated control valve (7). When switching on, the movement is effected by means of a pulse of compressed air directly from the reservoir container (8) via the line (9). When switching off, the shut-off valve (5) is moved via the line (11) in the opposite direction by means of a pulse of compressed air which is assigned to one of the limit positions of the piston (2). <IMAGE>

Title: Improvements in or relating to relays, particularly applicable to automatic regulating apparatus for alternating currents
IPC: G05F1/12
Filed: 1927-12-15
Abstract: 302,799. Brookhirst Switchgear, Ltd., and Rattenbury, G. Dec. 15, 1927. Regulation, automatic.-A relay A for use on A.C. circuits and particularly for voltage regulation is made sensitive to slight voltage variations by having connected in series therewith a highly saturated choke F which has a large impedance relatively to that of the relay. The relay arm C completes the circuit of one or other of the operative devices D, E, which may control regulating motors or, according to the Provisional Specification, transformer tap switches. A compounding effect can be obtained by the use of a current transformer M and a resistance K. Owing to the saturated choke, an abnormal voltage rise might produce excessive currents through the relay. The harmful effect thereof can be obviated by including in the series circuit another relay and a normally shorted resistance. Upon excess current the second relay removes the short from the resistance, and also completes the circuit of the voltage lowering device E. As the relay A may be subjected to a rush of current at the moment of energization of the supply circuit to which it is connected, this relay may be adapted when completely de-energized to remove a short-circuit from a resistance in series therewith.

Title: Measurement of a cut tobacco stream
IPC: A24C5/34
Filed: 1971-07-20
Abstract: 1397929 Feeding tobacco HAUNI-WERKE KORBER & CO KG 19 July 1972 [20 July 1971 9 Nov 1971] 34043/71 Heading A2C [Also in Divisions B8 G1 and G3] The quantity of tobacco or filter fibre in a stream in a cigarette rod machine is determined by measuring the force imparted to a rebound surface 78 against which the stream is projected at constant speed. The measurement is used to keep the quantity per unit time constant. The force is measured by the deflection of the surface against a spring or its own weight; a signal, taken from a potentiometer 79 copuled to the surface, is compared with that from a desired value potentiometer 82. As shown, any difference operates a servomotor 76 which adjusts a variable speed gear 68 between a drive motor on the rod forming machine (Fig 1, not shown) and rollers 32, 64 driving conveyors 31, 63. The fibres are swept off the latter conveyor by a constant speed brush roller 69 which projects them against the surface 78. If the rod forming machine is operating at, e.g., less than its normal speed less material is required per unit time; to prevent the system maintaining the normal flow the speed of the rod drive is measured by a tachogenerator 92 whose output is inverted at 89 to provide a compensatory signal to the control system at 87. From the deflector plate the material falls into a duct 1 in the rod forming machine, but in Figs. 3..5 (not shown) it is brushed in by a brush roll co-operating with a corrugated or mechanically oscillated surface to ensure even distribution. The complete feed comprises a hopper 36 from which material is taken by the belt 31 An intermediate store is formed between a brush roller 42 and a spiked roller 46. The level in this store is kept at a prescribed value by a system comprising a photocell 47 which controls the position of a paddle roll 52 by an electromagnet 49. The material is passed to a high speed conveyor 57 by a beater roll 53, from which the heavier ribs are collected and conveyed away at 61, 62, while the lighter material falls on to the conveyor 63. Alternative control systems In Fig 6 (not shown) the stream of material is conveyed to the rebound surface at constant speed, the output quantity being regulated by movement of a deflector plate in response to the control signal. Deflected material is taken away by a suction duct (441, Fig 7, not shown). Limit switches associated with the deflector plate are connected to AND gates, the other inputs of which receive timid pulses: their outputs pulse a servomotor which either adjusts the speed of the first conveyor (331) or (Fig 8, not shown) the speed of the spiked roller (346), thereby keeping the flow within the range of adjustment of the deflector plate.
