Patent GB-430394-A (GB)
Abstract: 430,394. Valves. JUNKERS & CO., GES., 35, Junkersstrasse, Dessau, Germany. Oct. 11, 1934, No. 29152. Convention date, Oct. 11, 1933. [Class 135] In a regulating device for gas-heated appliances comprising a gas-supply valve 25 controlled by the temperature or pressure of the medium being heated, a safety-cut-off valve 18 for controlling the gas supply and an ignition valve 44, these valves are arranged in a single block or casing with their axes converging and also with the axes of their actuating members substantially converging to the same point. The axes of the valves also lie in a common plane. The valve 25, Figs. 1, 2 is actuated by the differentially expanding members 32, 33 through a lever 31 and a push rod 29. The lever 31 is mounted on the reduced end 30, Fig. 2, of a slantwise-adjustable screwed spindle 34 which carries a pointer 38 moving over a scale. In operation, the stop cock 15 is first opened and then the ignition valve 44 so that gas passes from the inlet 11 by way of passages 24, 23, 22 to the back of the safety cut-off valve 18. The gas issuing from a hole 48 in the heatresponsive diaphragm 19 is ignited and the flame 49 so formed causes the valve 18 to open so that an increased supply of gas passes from the passage 16 to the main burner 13.

Title: Improvements in or relating to transistorised amplifiers
IPC: H03F1/34
Filed: 1960-12-15
Abstract: 965,666. Transistor amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 15, 1960 [Dec. 18, 1959], No. 43213/60. Heading H3T. A transistor amplifier having a high imput impedance has the collector of a first emitterfollower transistor directly connected to the emitter of a second transistor, the base of the second transistor being connected for signals to the emitter of the first transistor and its emitter being connected for signals to a tapping on the emitter resistor of the first transistor. Signals from a high ohmic source are supplied through input terminals 1 to the base of emitter-follower transistor 2 having an emitter resistor constituted by partial resistors 3, 4, the collector of this transistor being directly connected to a second transistor 5 which has its base connected through blocking capacitor 6 to the emitter of transistor 2 and its emitter connected through blocking capacitor 7 to junction point 8. Since the signal voltages set up at the base and emitter of transistor 5 and also at the collector and emitter of transistor 2 are substantially equal to the signal voltage at the base of transistor 2, the apparent resistance of resistor 3 is increased by a high factor. Bias current is supplied to the base of transistor 5 through resistors 10, 11, 12 and thence to the base of transistor 2 via resistor 9, the apparent resistances of resistors 9, 10 also being increased. Optimum results are obtained when resistor 9 is connected in series with blocking capacitor 6 between the base and emitter of transistor 2 and resistor 10 connected in series with blocking capacitor 13 between the base and emitter of transistor 5. When the amplifier is used for amplifying D.C. signals, the blocking capacitors 6, 7, 13 are replaced by Zener diodes and if the signal source has a low internal resistance a parallel combination of a resistor and an inductance coil is connected in lead 16.

Abstract: 993, 575. Dyeing felts. M. CASSE. Nov. 16, 1962 [Dec. 6, 1961], No. 43389/62. Heading D1L. Apparatus for dyeing felt blanks, hats, cloches or the like comprises perforated cones on which the felt blanks or the like may be placed, the cones being mounted with their axes horizontal on a vertical tubular wall which may be cylindrical or prismatic in cross-section and dye liquor being pumped through the cones. As shown in Fig. 1 the perforated cones 21 carrying the felts A are detachably mounted on the inside wall of a cylinder 7 such that the interior of each cone communicates, via hollow connecting stubs 24, 25, with an annular space II formed between the wall 7 and an outer jacket 8, the space II being sealed at its upper and lower ends and being provided with an cutlet pipe 19 leading to the inlet side of a centrifugal pump 2. Wall 7 encloses a space I having a removable lid 11 which may be clamped down by bolts 14 so that flanges 12 on the lid engage resilient sealing means 10. Space I is sealed at its lower end by a flow 5 provided with an inlet tube 4 leading from the high pressure side of the centrifugal pump 2. Dye liquor from pump 2 passes through the tube 4 and is deflected by a conical plate 36 into contact with a spirally arranged, steam filled tube 33 to be heated before passing into the vicinity of, and through the felts A. The liquor is then returned from the space II to the pump 2 via the tube 19. The means (see Fig. 2) for connecting the cones 21 to the wall 7 comprises, on the wall 7, a stub tube 29 having an inclined flange 31 and a complementary stub tube 24 formed on the unperforated lower wall of each cone, claws 26 being provided on stub 24 to be slid behind the flange 31. The stubs are thus forced together by the weight of the cone acting on the inclined flange. In a further form, Fig. 5, the cones C<SP>1</SP> which have an elliptical cross-section are mounted on and have access to the inside of a tube 7a by means of connecting stubs as described above. Tube 7a is clamped by a nut 73 threaded on a rod 72, to a flanged opening 67 beneath which is the rotor 66 of a centrifugal pump. Dye liquor is pumped from the space Ia (enclosed by the tube 7a) into the space IIa confined within the outer jacket 8a (which is triangular in cross-section) from which space the liquor passes through the felts and cones back to the central space Ia. A subsidiary vat D may be provided in parallel to the main dyeing vat so that the progress of the dyeing may be monitored on specimen felts. The subsidiary vat may also be used to introduce additional dyes and substances into the main vat. Pressure gauges 54, 55 (see Fig. 1) for spaces I and II and a safety valve 56 are provided. A thermometer 57 indicates the temperature of the bath.

Title: Gyroscopic apparatus
IPC: G01C25/00
Filed: 1975-10-22
Abstract: 1514780 Automatic control FERRANTI Ltd 20 Oct 1976 [22 Oct 1975] 43429/75 Heading G3N An inertial platform and at least one "dynamically-tuned free-rotor gyro" mounted thereon is aligned during run-up of the gyro by a procedure in which the outputs of two accelerometers (which are also sensitive to tilt) are combined with the outputs of gyro pick-offs to appropriately energize respective torque motors. The description sets out three distinct steps of alignment procedure. The gyro is defined as having an inertial element mounted on a drive-shaft by a spring coupling so that it is free to pivot about another axis, the spin frequency being equal to the natural frequency of vibration of the element when rotating on its spring support. Pick-offs detect motion about two perpendicular axes in the plane of rotation and thus one such gyro is equivalent to two single-axis gyros. The platform may carry a second such gyro or a normal single axis one. It is explained that initial alignment can be made quickly by the invention, utilizing the period while the rotor is still below normal speed.

Abstract: 1,221,055. Packing articles in bags. A.M.F. Inc. 30 Sept., 1968 [29 Sept., 1967], No. 44465/67. Heading B8C. Apparatus for packaging articles comprises a flighted infeed conveyer 10 for transporting articles to a predetermined position 12 and having means for varying the separation of the conveyer flights, means for providing an inflated bag at a position 14 and means for engaging the article at the predetermined position 12, inserting it into the inflated bag at 14 and moving the filled bag on to a removal conveyer 24. Infeed conveyer.-The infeed conveyer 10 comprises a pair of spaced belts 34, 36 and a plurality of flight bars 38 (on conveyer 34) and 40 (on conveyer 36) defining pockets 42 into which the articles are loaded. At their upstream end, the belts 34, 36 pass over driven wheels 46, 48 which are joined by bevel gears 68, 70, 72 and held in fixed relation by friction, applied by a cone on shaft 50. Slackening of the cone permits relative rotation of the wheels 46, 48 and the size of the pockets 42 can thus be varied. Pusher device.-The articles are transferred from the infeed conveyer into the inflated bags by a pusher 22. The pusher 22 is mounted on arm 194 pivoted between two endless chains 110, 112 which run over sprockets 114 and 116 and 118, 120 (not shown) and are supported by horizontal supports 122, 124 and inclined supports 126, 128. The pusher moves right into the bag so that the article therein presses against the bag and frees it from its mounting, and then retracts. Motion of the pusher is controlled by rollers 198, 199, 200 mounted on arm 194 by arms 202, 203, 204 respectively. These rollers engage tracks 225, 210, 217, 214 206 and 222 mounted between chains 110, 112 and force the pusher to move in the predetermined manner. Bag-opening device.-Trays 300 are slidably mounted on rails 296, 298 and a pile of bags, each attached by a flap adjacent the opening are mounted thereon. The tray is moved below the scoop-jaws 230, 232 which are pivoted on arms 234, 236 about vertical axes 241, 242 and the scoop jaws are pivoted until the ends of the scoop-jaws situated over the bags are close together. The bag is inflated by a jet of air, and the scoop-jaws are pivoted apart until they engage and hold the mouth of the bag. The pusher 22 pushes the article between the scoop-jaws and into the bag and forces the article against the back of the bag, separating the bag from its mounting on tray 300 and the scoop-jaws and transferring it to the conveyer 24. If the article is fragile, the pusher may be equipped with a bag-stripping member which engages the bag mouth before the article engages the back of the bag. Control.-The infeed conveyers and pusher are driven by chains from a centrally mounted motor, and the pivoting of the scoop-jaws is controlled by a cam and levers. A photo-cell 312 detects whether an article is in the pocket 42 and if the article is absent, turns off the jet of air so that the apparatus is not fouled by an empty bag.
