Abstract: 409,629. Meters for granular material. SOC. DES COMPTEURS VOLUMETRIQUES, 110, Boulevard SÚbastopol, Paris. Dec. 14, 1933, No. 35180. Convention date, Dec. 29, 1932. [Class 69 (i).] A meter for granular material comprises a measuring chamber 3, Figs. 1 and 2, and a hopper 5, both carried by a balance beam 2 weighted at 4. In the position shown, grain passes from a fixed feed hopper 15 via the hopper 5 to the chamber 3 ; when the latter is full, grain rises in the hopper 5 until the weight 4 is overcome, and the chamber 3 and hopper 5 descend. During the descent, a roller 13 on a lever 9 frees a door 14 which then closes the feed hopper ; subsequently, a projection 18<a> encounters a fixed stop 20 and moves a pivoted member 18 to release the bent end of a rod 17 from a member 19, so that a spring 11 acts to close a door 6 and to cause the movement of the member 18 to continue so that a projection 18b encounters a projection 25<a> on a lever 25. The lever 25 is thus moved to release the bent portion of a rod 24 from a member 26, and the door 21 is opened by the weight of grain in the chamber 3. During emptying, the chamber 3 rises and compresses a spring 12 ; when emptying is complete, the door 21 is closed by a weight 23, the projection 25 moves the projection 18<b> and the member 18, and the spring 12 is set free to return the doors 6, 14 to their initial positions.

Title: Improvements in constant speed gear units
Inventor: WESTBURY ROY
IPC: F16H47/04
Filed: 1958-11-05
Abstract: 871,576. Variable-speed gear. HOBSON Ltd., H. M. Nov. 4, 1959 [Nov. 5, 1958], No. 35569/58. Class 80 (2). A split-torque variable-speed gear particularly for driving an alternator at constant speed from an aircraft jet engine comprises an hydrostatic primary and secondary pump and epicyclic gearing combination providing wholly mechanical drives at different ratios when the primary pump is locked and when the secondary pump is locked, the ratio of these two ratios (overall speed ratio) being 2: 1, that is, less than the overall speed range of the jet engine which is 2.5: 1. The gear covers the overall speed range of the jet engine since the primary and secondary pumps, which normally function as a pump and a motor respectively, can interchange their functions so that the secondary pump drives the primary pump. The preferred embodiment of the invention is shown in Figs. 8 and 9 of Specification 871,575, and has a driving planet carrier having stepped planets, a first planet pinion of which meshes a ring gear driving the primary pump and also meshes a sun on the output shaft, and a second planet meshing through an idler planet a sun gear driving the secondary pump. In an alternative embodiment, two epicyclic gears are provided having a common planet carrier driven by the input shaft, sun gears fast on the output shaft and ring gears driving respectively the primary and secondary pumps. In a further embodiment an input driven carrier P1 has a planet meshing a sun S 1 fast on an output shaft 4 and meshing a ring gear A1 driving the primary pump P, a second planet meshing a sun S2 fast on the output shaft and a third planet P3 meshing through an idler I a sun S3 driving the secondary pump M.

Title: Improvements in or relating to transistor amplifier circuit arrangements
IPC: H03G1/00
Filed: 1960-10-19
Abstract: 885,811. Transistor amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 19, 1960 [Oct. 22, 1959], No. 35855/60. Class 40(6). A gain control arrangement comprises a pair of transistors with a common emitter resistance 3 and with the signal applied to the bases of both. A gain-controlling current is applied to the base of the first transistor 1 and the signal is taken from the collector circuit of the other, across a resistor 6; the base potential of this transistor is maintained constant by means of a potentiometer 7, 8. In addition a self-bias resistor 10 decoupled by condenser 9 may be placed in the emitter lead; this is stated to allow of a lower value to be assigned to resistors 7, 8 thus improving the thermal stability of transistor 2. The arrangement is such that an increase in the control current to the base of the transistor 1 increases the D.C. voltage across resistor 3, so biasing transistor 2 back to a region of lesser gain, and at the same time increase in gain of transistor 1 produces a larger signal across resistor 3, so reducing the signal between base and emitter of transistor 2.

Title: Improvements in or relating to machines for feeding mold charges of molten glass
IPC: C03B7/086
Filed: 1928-12-05
Abstract: 316,837. Wade, H., (Miller Inc., W. J.). Dec. 5, 1928. Delivering molten metal.-Relates to a feeder of the reciprocating-plunger type and consists in using a single driving-device for reciprocating the plunger and operating the shears, and in providing means for varying the stroke of the plunger, and its position in respect to the discharge outlet, independently of the operation of the shearing mechanism. The device consists of a plunger 5, Fig. 1, which reciprocates above an outlet 3 in the floor of a forehearth 2. The glass is extruded through the outlet, and its formation into separate charges is assisted by shears 146 which are arranged close beneath the outlet. The plunger is carried by a stem 7 freely rotatable within a sleeve 8 and adjustable longitudinally within the sleeve bv means of nuts 10. The sleeve is mounted on gimbals within an aperture 14 in a beam 15, and the beam can slide freely on parallel vertical standards 17. A shaft 31, Fig. 2, is journaled in supports 29 carried by the standards 27, and a lever 32, adjustably clamped to the shaft 31, has a bifurcated end 34 which engages beneath the beam 15. A lever 35, secured to the end of the shaft 31, is connected by an adjustable link 38 with a sleeve 39 which is pivoted to a beam 59. This beam is also pivoted to the lower part of one of the standards 27, and the levers and link form with' the standard a link parallelogram. A cam lever 52, formed with a longitudinal slot 53. is pivoted at its front end to the sleeve 39 and also carries a roller 57 which rides on a cam 87. The slot 53 embraces a sleeve 51 which can be moved horizontally by means of a screw shaft 45. Rotation of the cam rocks the lever 52 about the sleeve 51 and also causes reciprocation of the plunger 5 through the link 38, lever 35 and shaft 31. By loosening the securing nut of the sleeve 51, the sleeve can be moved along the slot 53 thus shifting the fulcrum of the lever 52 and increasing or decreasing the stroke of the plunger 5. The cam 87 is secured to one end of a shaft 63 operated by a motor 99, the other end of the shaft carrying a cam 133 that operates the shears 146 as described in Specification 318,063. The cam 87 can be turned in its shaft by means of a gear wheel operated by a knob 82, and it can be changed for another with a different profile. By turning the cam in respect to the shaft 63, the relation between the plunger movements can be adjusted in relation to the stroke of the cutting-device, thus permitting the stroke of the plunger to be adjusted in relation to the outlet aperture without disturbing the regular timing of the shears. The apparatus may be assembled with the various operating mechanisms mounted on either side of the forehearth. Specification 259,965 also is referred to.

Title: Improvements relating to the preparation of calcium carbide
IPC: C01B32/942
Filed: 1953-12-24
Abstract: In the shaft furnace production of calcium carbide from calcereous material containing calcium oxide as such or as hydroxide or carbonate and solid carbonaceous fuel consisting substantially of carbon, a ratio of the solid reactants, expressed as calcium oxide to carbon, of between 1 : 4 and 1 : 2 is employed.  The high temperature required in the process is provided by an oxygen-containing blast which burns a portion of the fuel, resulting in the production of an inflammable gas which escapes through the top of the furnace and a layer of molten carbide in the lower part of the furnace which is discharged therefrom continuously or intermittently.  Low exhaust gas temperatures of 80-200 DEG  C. may be obtained.  According to the example, using a charge consisting of a mixture of 80 kg. of coke and 55 kg. of limestone (CaO : C of about 2 : 5) and a blast consisting of 77 per cent of technical oxygen and 23 per cent of steam, a furnace temperature of 2650 DEG  C. and an inflammable gas temperature of 180 DEG  C. was obtained.  The resultant carbide yielded 240 l. of acetylene per kg. of carbide.
