Title: Improvements in and relating to electric control and indicating means comprising electric discharge tubes
IPC: H04J3/04
Filed: 1950-04-19
Abstract: 704,753. Protective arrangements. GENERAL ELECTRIC CO., Ltd., and HOLLIDAY, J. H. July 18, 1951 [April 19, 1950], No. 9618/50. Class 38(5) [Also in Group XL(c)] The Figure shows a circuit for indicating the presence of reverse current in a given phase of a six phase rectifier system and for determining the time of occurrence of such current. The thyratrons 11-16 have a common cathode resistor 17 and are biased to non-conductivity by the voltage drop across resistors 17, 18. In the event of reverse current in a given rectifier phase (not shown) a positive pulse is applied to the associated saturating transformer 19 which may be of the type described in Specification 704,746. The pulse is limited in its positive swing by resistor 41 and diode 31 and if the thyratrons 11-16 are non-conducting then the associated thyratron will fire, the associated indicator lamp 21-26 and the relay 27 is energized. The increase in current flow through resistors 17, 18 reduces the voltage between anode and cathode of the thyratrons and increases the grid bias so that a subsequent pulse on another phase has no effect on the operation of the circuit. The circuit is re-set by closing and opening switch 55. Capacitor 50 is charged from the H.T. supply via resistors 51, 17 and 18 and is periodically discharged via thyratron 52 when this is rendered conducting by a positive pulse applied to its control grid. The triggering pulses may be synchronized with the A.C. supply connected to the poly phase rectifier system and the time constant of the charging circuit may be made such that capacitor 50 charges to some 75 per cent of the H.T. supply voltage. When inverse current occurs in the rectifier system and a thyratron fires then the effective H.T. supply falls to a low value and capacitor 50 commences to discharge, Fig. 2 (not shown). Thus the point along the charging curve of the capacitor at which the charging ceases is a measure of the time of occurrence of the fault and may be determined by the photographing of the curves of voltage changes across the capacitor which may be displayed.on a cathode-ray oscilloscope having a long after-glow screen. In a modification the capacitor 50 is charged through a series diode so that on the occurrence of a fault the voltage across it remains constant at a value indicative of the time at which the fault, occurred.

Title: Automatic control device for the overflow valve of injectors
IPC: F04F5/48
Filed: 1937-04-06
Abstract: 478,785. Injectors. FRIEDMANN, L., (trading as FRIEDMANN, A., [Firm of]). April 6, 1937, Nos. 9721 and 9722. Convention dates, April 8, 1936 and Oct. 26, 1936. [Class 711 An overflow valve 15 of an injector is closed by a plunger-operated lever 13 when the injector is working. The plunger is connected to a piston 10, Fig. 1, or a discharge valve 17, Fig. 2, arranged in a diaphragm between the delivery chamber 5 and the discharge chamber 8. The piston or valve and plunger are acted upon by the discharge pressure to withdraw the plunger to release the overflow valve when the injector is stopped. The steam, combination, and delivery nozzles are shown at 2, 3, 4 respectively. A discharge valve 7 separate from the piston 10 is provided in the arrangement shown in Fig. 1. The piston is dispensed with in the construction shown in Fig. 2. The check-valve 17 is forked to embrace a collar 19 on the plunger 25. In a modification, the check-valve is of annular form, and a collar on the plunger 26 seats upon an annular seat 21 thereon. The port 24 is of greater diameter than the port 26 so that the plunger is subjected to a differential liquid pressure to depress it when the injector is stopped.

Title: Improvements in or relating to method of treating starch material and the products resulting therefrom
IPC: C08B30/20
Filed: 1945-04-18
Abstract: The water-moist linear starch fraction known as amylose or A fraction starch is treated to obtain it in a water-free form without impairment of its initial water solubility by dissolving the water contained in it in a liquid inert to the starch fraction in respect of chemical action, gelatinisation and solvent action, and removing water from the material while the water is dissolved in said liquid. The moist fraction is mixed in the cold or with heating with a liquid such as methyl alcohol, acetone, ethyl alcohol, isopropyl alcohol, tertiary butyl alcohol, diacetone alcohol, n.propyl alcohol, ethylene glycol mono methyl ether or dioxane.  N.butyl alcohol, sec. butyl alcohol, isobutyl alcohol, tertiary amyl alcohol and commercial mixtures of amyl alcohols may also be used, but in these cases a larger volume of solvent will be required.  Formamide, glycerol and ethylene glycol are stated to be unsuitable.  The liquid containing part or all of the water may then be removed either by filtration followed by evaporation of residual liquid at normal or sub-atmospheric pressure, or by so adjusting the ratio of dehydrating liquid to water that nearly all the liquid may be removed by azeotropic distillation.  The drying temperature should be kept below 140 DEG C. The process may advantageously be carried out in two stages, e.g., most of the water is removed by means of a solvent such as methyl alcohol which is miscible with water in all proportions, and then the remainder by a liquid such as butyl alcohol which forms an azeotropic mixture.

Filed: 1947-04-11
Abstract: 626,774. Pie moulding machines. FRANK, G. W. April 11, 1947, No. 9765. [Class 87 (ii)] In a pie moulding machine the mould comprises an openended cylinder 4 in which is adapted to be fitted a liner in two or more separate complementary parts, the liner forming the base and wall of the mould cavity. As shown the liner is in two parts 1, 2 each forming half the base and half the wall of the mould cavity and the upper edges 3 are turned over to facilitate removal from the cylinder 4. The two parts of the liner are placed in the cylinder, which is placed on the bed of the machine, a piece of dough placed therein and a plunger 5 brought down to shape the dough into a pie shell. This is then filled, covered with a layer of dough and a lidding plunger brought down to form the lid and unite it to the shell. The liner is then removed with the pie from the cylinder 4 and the liner halves stripped from the pie which is thus extracted from the machine without damage. The plungers may be heated to prevent the dough from sticking to them.

Title: Improvements in or relating to the taking of samples from dust-laden atmospheres
Inventor: WRIGHT BASIL MARTIN
IPC: G01N1/22
Filed: 1957-03-26
Abstract: 841,698. Interrupters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 28, 1958 [March 26, 1957], No. 9854/57. Class 38 (5). [Also in Groups XX and XXIV] A turntable driven by a battery-powered miniature electric motor is given a timed sequence of rotary movements, the motor being controlled by a set of three spring contacts 58, 59, 60, which are operated to open and shut in a predetermined cycle by a clockwork mechanism. The inner and outer contacts 58, 60 are connected to the negative pole of the battery, while the centre contact 59 is connected to the positive pole. Thus the motor is switched on if the centre contact touches either of the other two. The double snail cam 72 is carried on the underside of the clockwork centre wheel spindle 71, and thus rotates completely once every hour. The cam bears against two V-shaped levers 78, 79, pivoted at 80, which engage contacts 59, 60. A further bell-crank lever, also pivoted at 80, can also engage contact 60. Initially the contacts are all open (Fig. 6a, not shown). At 1¢ minutes before the hour or half-hour, the lever 79 slips off the snail cam first, since it is shorter than the other. Pressure on contact 60 is released so that it touches 59 and starts the motor (Fig. 6b). The turntable, and a cam plate 69, are given a quarter turn, and at the same time the motor is switched off, since the bell-crank arm 77 falls into a step 76, so that its other arm 77a pushes contact 60 away from contact 59. After 1¢ minutes (i.e. at the hour or half-hour) the longer lever 78 slips off the snail cam, and allows contact 59 to touch 58, so re-starting the motor. Another quarter turn is given to the turntable and also cam plate 69. The toe 81a of a latch lever 81, which has been riding on the edge of cam plate 69, now falls into the step 76, and releases its pressure against contact 58, so that contact is again broken and the motor switched-off. This condition is now maintained for 28¢ minutes, after which the whole cycle is repeated. The arrangement is such that each time the cam plate is driven round a quarter turn, the clock spring is wound by the same amount. Means are provided to prevent the clock from running down if the motor fails to start.
