Title: Improvements in inductance coils
IPC: H01F17/04
Filed: 1933-02-01
Abstract: 417,376. Inductances. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, TURNER, H. C., and POLGREEN, G. R., c/o Salford Electrical Instruments, Ltd., Silk Street, Salford, SMITH, C. G., and SMYTH, C. N., c /o General Electric Co., Wembley, Middlesex. Feb. 1, 1933, No. 24137/34. Divided out of 417,378. [Class 37.] The winding of a variable inductance is arranged on a part of the core which is in the form of a bar arranged within and extending across a hole in the second part of the core and rotatable to vary the reluctance of the magnetic circuit. In the construction shown in Fig. 1, the core part a has an oval hole, the diameter D1 being greater than D2. The core part c carrying the winding is placed within the hole in the part a so as to be rotatable about a central axis. As the part c is rotated, the length of the air gap between the two parts is varied, thereby varying the reluctance of the magnetic circuit. Alternatively, the hole in the core part a may be circular as shown in Fig. 2, the outer perimeter being of any shape other than a circle concentric with the hole. The inner core part may be shaped as shown at f or g and may have its edges at right-angles to its face or bevelled as shown to prevent binding, the edges of the hole being correspondingly bevelled. When the coil is enclosed in a screen, as shown in Fig. 3, the screen is formed in two relatively rotatable parts 5, 6, the part 5 carrying the outer part 1 of the core and the part 6 carrying the inner part 2. The inductance is adjusted by rotating the screen part 5 relatively to the part 6. The parts may then be fixed if a coil of fixed inductance is required. The core may be a dust core pressed or stamped in dies, or it may be built up from laminations. The invention is applicable to filter coils, telephone loading coils, and tuning coils for broadcast receivers.

Title: Improved form of seed sowing machine
IPC: A01C7/04
Filed: 1945-12-04
Abstract: 588,050. Seed sowers. PARTRIDGE, J. Dec. 4, 1945, No. 24189/44. [Class 6 (i)] In a pneumatic seed-sowing machine a tube provided with suction nozzles is caused periodically to move parallel to itself from a position adjacent to a seed container, where seeds are sucked against the nozzles, to a position above a series of discharge hoppers where the suction is automatically discontinued to permit the seeds to fall into the hoppers. In the form shown, seeds are lifted individually from trays 1 by suction nozzles 8 carried by a tube 3. The tube is mounted on brackets 7, 7<SP>1</SP>, which are attached to links 6, 6<SP>1</SP> carried on a shaft 5. The shaft 5 is caused to oscillate about its axis, the motion being transmitted from the land wheels 16 of the machine by means of gearing 15 and a crank rod 18. The oscillating motion of the shaft 5 causes the tube 3 periodically to be drawn parallel to itself over guides 4, 41 from its position over the seed trays 1 to a position adjacent to the open upper ends of drill tubes 2. As the tube reaches the latter position, a cranked pin 11 carried on the end cap 10 of the tube 3 strikes against a projection 12 on the guide 4, causing the cap, which is pivoted, to open and, by releasing the suction, to permit the seeds to fall into the drills. The suction is produced by a bellows 9 driven from the land wheels by gearing 15 and a crankshaft 13a.

Abstract: 837,130. Friction gearing; screw-and-nut gearing. ANDERSON CO. July 31, 1957, No. 24265/57. Classes 80 (1) and 80 (3). In motor-driven screw-and-nut mechanism for longitudinally moving a tubular member 15, the screw 43 is driven by the motor shaft 20 through epicyclic friction gearing 16 which slips on overload to prevent damage should the member 15 be held stationary while the motor (not shown) is running, the pressure between the frictionally engaging parts being adjustable. The friction gearing 16 comprises planetary elements 27 which are rotatably mounted in cruciform openings in a tubular cage 41 of brass or nylon secured to the driven screw 43. Each element 27 has two radially enlarged toroidal portions engaging grooves in an inner race 25 secured to the driving shaft 20 and grooves in a split outer reaction race 26a, 26b. The non-rotatable race parts 26a, 26b are slidable in a fixed casing part 21b and are urged towards each other by spring 31, 33 adjusted respectively by rotation of a threaded casing part 21a and of a threaded member 34. An opening 39 allows insertion of a tool to engage recesses in the circumference of the member 34 to effect adjustment thereof. The screw 43 may drive the member 15 through an ordinary non- rotatable nut, but as shown the screw 43 engages planetary elements 51 which are rotatably mounted in a freely rotatable cage 50 and which engage annular grooves 53 in the member 15. The elements 51 have unequally spaced radially enlarged surfaces 52. Axial movement of the cage 50 is limited by stops 54, 55 on the screw 43. The member 15 is guided by a cup-shaped plate, which may be of nylon held by the stop 55. In modifications of the friction gearing 16 the spring 31 is dispensed with and the race part 26a bears against a fixed flange, the single loading spring 33 being adjusted by the member 34, or by an internally threaded member replacing the member 34. Alternatively the race part 26a may bear directly against the flange of an adjustable casing part 21a, the single spring 33 bear directly on the motor housing 18, and the inner race 25 be slidably keyed on the shaft 20 so that adjustment of the spring 33 is obtained by rotation of the casing part 21a. In a further modification both the inner and outer races are split and are loaded by respective adjustable springs. It is stated that the mechanism may be used in reverse to rotate a shaft 20 by axial movement of the member 15. It is also stated that the gearing 16 may be used, without the screw and nut mechanism, to convey drive between the shaft 20 and a pulley mounted on the cage 41, said gearing slipping on overload.

Title: Improvements in devices for driving the turntable of phonographs, record players, etc., at a number of speeds
IPC: G11B19/265
Filed: 1957-08-01
Abstract: 871,921. Driving sound-reproducing machines. STAAR, M. Aug. 1, 1957 [March 22, 1957], No. 24373/57. Class 40 (2). A gramophone turn-table speed-changing device in which a friction wheel 3 transmits the drive from a stepped driving pulley 4 to the turn-table 1 is characterized by the provision of a position in which the friction wheel is disengaged from both the pulley and the turntable. The wheel 3 revolves on an axle carried by the lever 5 pivoted by the pin 19 to the arm 20. A tension spring 18 keeps the friction wheel 3 in contact with the turn-table 1 and the pulley 4. The arm 20 is raised and lowered on the pivot 11 by a tenon 24 which engages in a slot 23. The bell cam 9 is loosely mounted on a shaft 6 and is biased by a spring 33 to rotate in such a direction as to move the arm 20 down the pivot 11. The shaft 6 also carries a control lever 8 and a disc 28 which has a projection 29. Both these components are secured to the shaft which is biased by the spring 40 to rotate in the opposite direction to the bell cam 9. The pivot 11 also carries a lever 15 which has a tension spring 13 attached to the extension 12 and a further extension 31 which co-operates with the projection 29. The main part of the lever is bent over at 25 and 26 and carries a tenon 27 which engages the bell cam 9. Operation.-When the lever 8 is rotated in the direction opposite to the arrow F, Fig. 2, the projection 29 engages the tenon 24 and rotates the bell cam 9, thus raising the arm 20 and engaging a lower speed. The tenon 27 engages the teeth 10 of the cam and overcomes the effect of the spring 33. On rotation of the lever 8 in the direction of the arrow F, the projection 29 leaves the tenon 24 and engages the extension 31, moving the tenon 27 out of engagement with the teeth 10 of the cam 9 and allowing the cam to rotate in the same direction as the lever. At the same time the part 25 of the lever 15 engages the lever 20 and rotates it about the pin 11, so that the wheel 3 moves out of engagement with the turn-table 1 and the pulley 4.

Abstract: 280,678. Marks, E. C. R., (williams Oil-O-Matic Heating Corporation). Oct. 4, 1926. Electrically controlling fuel and air supplies.- The circuit 24 of an electric motor 1 operating the blower fan and pump supplying air and liquid fuel through a conduit 3 and pipe 9 respectively to a burner in a furnace firepot 5 includes a tilting mercury switch 30 which is normally held in the closed position by a pawl 34 engaging a ratchet wheel 35 having its stem mounted in a cup containing solder. The cup is surrounded by a heating coil 38 arranged in the motor circuit 24 in parallel with a circuit 50 including a tilting mercury switch 51 which is held in the closed position when the burner is in operation but is opened if the burner is extinguished or fails to ignite. The passage of the whole current to the motor through the coil 38 when the switch 51 is open melts the solder in the cup and releases the pawl 34, thereby opening the switch 30 and stopping the motor until thA switch 30 is reset by the operator. The circuit 24 also includes a main switch 25, a room thermostat 26, and a safety control device 27 in the furnace or boiler, the thermostat 26 and safety control 27 operating automatically and not requiring manual resetting. The burner shown comprises a nozzle 10 which imparts a whirling motion to the fuel in one direction and a vane 11 fixed on the nozzle 10 for imparting to the air a whirling motion in the opposite direction. The spark coil 12 for igniting the fuel may be arranged in parallel with the motor 1. The switch 51 is operated by a Bourdon or pressure tube 16 connected through a tube 17 to a tubular coil 18 which contains expansible Liquid and is arranged in a casing 19 exposed to the heat of the burner flame, overheating of the coil being prevented by means of a baffle 22 in the conduit 3 diverting part of the air from the fan into the casing. The end of the tube 16 is connected by a link 53 to a pivoted lever 54 which is connected to a lever 58 by a slotted link 57 passing over a pin 59. The pin 59 is slidable in a. slot 61 in the lever 58 and is connected to the lever 54 by a spring 62.

Title: Process and apparatus for the preparation of pyridine carboxylic acids
Filed: 1954-08-24
Abstract: A pyridine carboxylic acid is prepared by oxidation of an alkyl pyridine with nitric acid in the gaseous phase.  Catalysts such as Fe2O3, V2O5, CuO, MoO3, SeO2, or preferably B2O3, or mixtures of these oxides, or boric acid, may be used, either as solids bedded on carriers, by injection into the reaction chamber or by dissolution in at least one of the starting materials.  It is preferred to use nitric acid of 10-70 per cent by weight concentration at temperatures within the range 120-130 DEG  C., the reactants being mixed before or after vaporization.  After completion of the reaction, the gas mixture remaining after the separation of the pyridine carboxylic acids may be mixed with oxygen and the gases thus formed washed with water to obtain nitric acid of a concentration suitable for re-use in the process of the invention.  In examples (1) into a vertical reactor tube packed with granulated pumice stone and provided with a heating jacket at the upper end is introduced a liquid mixture of 2-methyl-5-ethyl pyridine, nitric acid and a catalytic amount of boric acid, where the mixture is vaporized and brought to 230 DEG C.; the reaction products are cooled and collected at the bottom of the tube and distilled in vacuo, and the distillate is brought to pH 3.5-3.7, when nicotinic acid precipitates; (2) in the same apparatus gamma-picoline is converted at 240 DEG  C. in the presence of boric acid to isonicotinic acid; (3) 2.4.6-trimethylpyridine is similarly converted at 250 DEG  C. to isonicotinic acid; and (4) the same reaction as in example (1) is carried out in the presence of a mixture of B2O3 and SeO2 at 250 DEG  C.  An apparatus in the form of 2 concentric tubes, in which the annular space, which may be filled with a packing material such as Raschig rings or pumice granules, is utilized as the oxidation space, is also described.
