IPC: H01L/
Filed: 1974-04-10
Abstract: 1465609 Control of SCR ATELIERS DE CONSTRUCTION ELECTRIQUES DE CHARLEROI 10 April 197 4  [11 April 1973] 16058/74 Heading H3T [Also in Division H2] In a control device for a SCR Th including resistors R, R 2  capacitors C, C 1 -C 3 , diodes D 1 , D 2  and voltage limiting devices Z 1 , Z 2  connected as shown, a circuit B controls an electronic switch t 1 -t 3  which is connected between the gate of Th and the junction between D 1  and C 1  and the circuit B has three logic inputs which perform an AND function. One of these inputs is connected to the anode voltage of Th, another of these inputs is acted on by an optical-electronic control signal generator, such as photo transistor Ph, and the third input is connected to the capacitor C 1  so as to inhibit the action of the circuit B, when the voltage across the capacitor C 1  is below a certain value. In operation of the circuit as a rectifier or a chopper the capacitors C 1  and C 2  are charged as shown. The circuit B provides an output to the electronic switch t 1 - t3 when the anode of Th is positive, photo transistor Ph receives a light pulse and the voltage across C 1  is above a given value. The transistor t 3  then connects the positive voltage on C 1  to gate the thyristor Th. The control device transmits firing pulses of adjustable duration to the thyristor Th and in event of faulty firing or reblocking of the thyristor the control device automatically produces further firing pulses. A negative signal is applied to the gate of Th from C 2  in the absence of control. This blocking current is constant and the effect on the time of extinction of the carriers is reached immediately an inverse voltage is set up at Th. As the charging of energy-accumulating capacitor C 1  takes place with a phase difference of 90 degrees in relation to the voltage across Th the firing of thyristors in a rectifier bridge can take place with firing angles from 0 up to 180 degrees. A set of series connected thyristors can be controlled with the optical control device.

Title: Improvements in process and apparatus for separating metal pieces
IPC: G01N27/90
Filed: 1945-06-26
Abstract: 594,106. Magnetic separators. DU MONT LABORATORIES, Inc., A. B. June 26. 1945, No. 16293. Convention date, July 29, 1944. [Class 72] [Also in Group XL] In the separation of metal pieces of the same shape, size and material, but differing in core losses when subjected to alternating magnetic fields, the metal pieces are passed through a coil to which is applied amplitude-modulated high-frequency current and cause low-frequency signals to be applied at the input 1. Due to a circuit 20-20<SP>1</SP> there is a time delay in the building up of the output voltage of a tube 21 and in the firing of a blocking oscillator tube 33 when compared to the building up of the output voltage of a tube 4 and the firing of an oscillator tube 11. The firing potential of the tube 33 is lower than that of the tube 4. When the amplitude of the signal is sufficient to fire both oscillators 11 and 33, 11 fires first causing a decrease in the potential on the cathode of a tube 45 and there is an increase of current through a field coil 40 of a relay 41 so keeping a contactor 42 against a stop 44. The firing of the oscillator 33 has the reverse action, but it is not sufficient to counterbalance the effect of the oscillator 11. When the amplitude of the signal is only sufficient to fire the oscillator 33, the contactor 42 makes contact with contact 43, so causing a mechanical separating device to function.

Abstract: 545,525. Refrigerating. ELECTROLUX, Ltd. Nov. 14, 1940, No. 16469. Convention date, Feb. 3, 1940. [Class 29] Absorption systems.-A continuous-cycle inert gas system for a storage cabinet 36 has a divided generator, a part 13 of which is connected with a condenser 39 supplying only a low temperature ice-making evaporator 41 while the other part 10 is connected with a condenser 32 supplying a higher temperature air-cooling evaporator 34. The heat supply to the generator is divided and arranged so that either generator portion alone or both may be heated, or heat may be supplied only to a "pumping" coil 68 for maintaining liquor circulation. The part 10 of the generator surrounds a heating flue 11 extending downwards through the pumping coil, and is provided with semi-circular baffles 15, 14 located one below and the other above the connection of the part 13 with the part 10. Electric heating elements a, b, c, d are arranged in the flue at the positions shown corresponding with the pumping coil, the space below the lower baffle, the space between the baffles and the space above the upper baffle. The main current supply is controlled by a manual switch 19 and a thermostatic switch 18 responsive to the temperature of a thermal element 71 in the cabinet, the separate heating elements being controlled by a rotary manual switch 27. When the element b is switched in generated vapour is diverted by the baffles 15, 14 into the part 13 and is condensed in condenser 39 and supplied to evaporator 41, and little or no refrigerant is supplied to the other evaporator. When the element d is in action orly the cabinet cooling evaporator 34 is supplied with refrigerant by conduit 30 and condenser 32, whereas when the element c is in action part of the vapour flows through the part 13 of the generator to the condenser 39 and part to the condenser 32, and thus both evaporators are supplied. The inert gas flows from the absorber 61 through the usual heat exchanger 46 to the low temperature evaporator 41 and the mixture of vapours returns through the exchanger jacket. The upper higher temperature evaporator is connected with the gas heat exchanger jacket by supply and return pipes 53, 54. Refrigerant unevaporated in the upper evaporator flows through a conduit 56 into the lower evaporator.

Title: Improvements in or relating to valve tappets
IPC: B64C1/00
Filed: 1937-06-15
Abstract: 499,029. Valve gear. EATON MANUFACTURING CO. June 15, 1937, No. 16614. Convention date, Aug. 3, 1936. [Class 7 (vi)] In a valve-actuating tappet provided with hydraulic means for automatically taking up clearance comprising a tightly-fitting plunger sliding within a cylindrical bore in the tappet, means are provided for permitting a predetermined escape of fluid out of the hydraulic chamber. The plunger is fitted with a packing-washer 16, Fig. 1, of slightly yieldable material which prevents flow of liquid from the compression chamber 31 beneath the plunger when the tappet is lifted by its cam. The washer 16 is pressed upwards by a spring 18 against a flat washer 15 and a valve 14, also in the form of a washer and co-operating with a flange 26 on the plunger stem. Oil or other liquid is admitted by a groove 20 and port 21 to a supply chamber 30 above the plunger. A spring 13 extends the tappet until clearance is taken up, the outward movement of the plunger producing a vacuum underneath the plunger, causing the valve 14 to separate from the flange 26 and admit oil to the chamber 31. When the cam lifts the tappet, the washer 16 is forced outwards against the bore of the tappet and the valve 14 is pressed against the flange 26, thus sealing the plunger. A slight leakage of liquid, however, is provided by a spiral or other groove 32 extending from the centre to the periphery of the lower face of the valve 14 ; or the leakage may be obtained by one or both contacting faces of the washers being roughened. The packing-washer 16 may be of synthetic rubber or of lead or other soft metal or alloy. The pressure of the periphery of the washer 16 against the bore of the tappet also gives a frictional lag to reversal of movement of the plunger within the bore. Fig. 6 shows a modified form in which the plunger 56 operates within a separate cylinder 44 placed within the tappet bore and having a tubular extension 51 depending into a liquid supply chamber 55, and a non-return valve 53 separating this chamber from the compression chamber 64 beneath the plunger. In the form shown in Fig. 8, the hollow tappet 100, which may be used in the position shown or inverted, is fitted with opposed cup members 106, 107, the former being connected by a rod 108 flanged at 111 to the plunger comprising a valve member 112 and packing-washer 113 and operating within the other cup member. An extending spring 117 may be replaced by a sylphon bellows. The Specification as open to inspection under Sect. 91 describes another form applicable to push-rods, in which the lower end of the push-rod is seated on the plunger, which is fitted with a flanged packing-washer also acting as a non-return valve. This subjectmatter does not appear in the Specification as accepted.

Filed: 1940-11-18
Abstract: 546,781. Packing; non-metallic hollow ware. WATERS, H. F. Nov. 18, 1940, No. 16634. [Classes 66 and 94 (i)] Relates to a method of packing liquid or granular material in a container of the kind constituted by an outer carton with a fluidtight lining. According to the invention, a carton is so constructed that by moving the side flaps at the top of the carton outwards, the mouth of the lining becomes folded into a flattened form in the plain of the top of the carton, and can then be sealed hermetically to form a flat seal. The carton is made from a blank 1, Fig. 1, having longitudinal scored lines 2, 3, 4, 5 and transverse scored lines 6, 7, 8, 9 that defined the front and back panels 10, 11 respectively, and sides 12, 13. the front and back being connected by a bottom panel 20 with a central transverse scored line 21. The panel 11 has side pieces or guides 26, 27 each of which has an inclined edge 29. A lining 32, Fig. 2, is secured to the blank 1 by lines 33 of adhesive. This lining is of fluid-tight material which is composed of or coated with heat-sealable material, such as a sheet of paper with a coating of rubber hydrochloride or thermoplastic resinous material. After the lining is secured, the blank 1 is folded along the line 21 and the marginal portions of the folded lining are sealed by and pressure to convert it into a fluid-tight envelope open at the top..The sides of the carton are folded along lines 22, 23, Fig. 1. and secured by adhesive to form a container in flattened form, as shown in Fig. 4, with the guides 26, 27 tucked between the folds at the sides of the lining. In use, the blank is expanded, as shown in Fig. 5, with the guides 26, 27 tucked behind side folds or fins 34, 35 of the lining which are secured to the sides 12, 13 and the side flaps 16, 18 at the top of the carton. After the carton is filled the side flaps 16, 18 are folded outwards, and the mouth of the lining is spread out and flattened, as shown in Fig. 8, by the engagement of the guides 26. 27 with the fins 34, 35. The lining is then heat-sealed along the edges, and the top of the container is closed by folding the flaps of the carton. The guides 26, 27, instead of forming part of the carton blank may be made separate and attached to the blank by adhesives or staples.
