Title: Rotary internal combustion engine
Inventor: ALLENDER FORREST R
IPC: F02B53/00
Filed: 1966-02-24
Abstract: 1,143,462. Rotary internal combustion engines. CLAYG CORP. Feb.24, 1966, No.8229/66. Heading F1F. A rotary I.C. engine comprises a power rotor 8, Fig. 4, and a compression chamber rotor, two as shown, 10, 10<SP>1</SP>, coupled for synchronous rotation within a housing block 6 by external gearing (not shown), with the power rotor having a projecting lobe and the compression chamber rotor having a cavity with the lobe and cavity so shaped to form a sealed compression chamber between a lobe apex 28 and the leading face of the cavity and a sealed combustion chamber 147 between the apex and the trailing face of the cavity and transfer passage means which when the lobe has moved to a certain position transfers the compressed combustible gases from the compression chamber to the combustion chamber where they are ignited. The projecting lobes have a shape in which leading and trailing faces are joined by an apex with the leading and trailing faces each having a profile defined in polar coordinates by the equation:- where # has values from 0 degrees to (A +B)<SP>2</SP> - 5A<SP>2</SP>/-4A<SP>2</SP> where A = the radius of the power rotor and B = the distance from the tip of the lobe to the nearest edge of the circle of radius A and the cavities have a shape defined in polar co-ordinates by the equation;- R = -A<SP>1</SP> (A<SP>1</SP> +2B<SP>1</SP>) cos# where # has the values from where A<SP>1</SP> = the diameter of the compression chamber rotor and B<SP>1</SP> = the depth of the cavity. In operation, combustible gases from, e.g., a carburetter are admitted through ports 42 and compressed ahead of the lobes in chambers 46, Fig. 10, until top dead centre position, Fig. 16, is reached. The gases are then transferred through ducts 48 formed in the housing side plates to chambers 47 at the rear of the lobes and then ignited by spark-plugs located at 50. The expanding gases act on the lobes to rotate the rotor and are finally expelled through ports 44. A spring-loaded seal 32, Fig.8 is provided at each apex 28 and a toe-seal 36 at each side of each cavity. The toe-seal is hinged at 38 and urged by resilient means, e.g., a silicon rubber dowel 40 sealingly against the lobe.

Title: Improved speed regulating device
IPC: G05D13/00
Filed: 1926-03-26
Abstract: 265,805. Ferrant, A., and Asseler, J. d'. March 26, 1926. Variable-speed gearing comprises a friction gear pair 7. 10 actuated by a variably-rotating shaft 1 and automatically controlled so as to drive a shaft 11 at a substantially constant speed. A governor 15 influenced by the variable drive functions to move the constantly-driven friction wheel 10 axially to keep the speed of the latter constant. The invention is applicable for driving a dynamo from the wind motor described in Specification 227,051, [Class 110 (iii), Turbines &c.]. The governor 5 may be carried by a countershaft 12 which is driven through a pair 2, 3 from the shaft 1, and which drives through a pair 4. 5 the shaft 6 of the driving disc 7 of the variable gear. The roller 10 is moved axially by a lever 16 supported on a fixed pivot 19 and having a suitable slot 18. A rod 17 slidable in fixed guides 22, 23 is moved up and down by the governor and by means of a pin &c. 17<1> engaging the slot 18 effects the required angular movements of the lever 16.

Title: Process and apparatus for coking coal
IPC: C10B1/04
Filed: 1926-03-27
Abstract: 249,886. Urbana Coke Corporation, (Assignees of Parr, S. W., and Layng, T. E.). March 27, 1925, [Convention date]. Coking processes.-Coal is preheated in a rotary drum to a temperature 20' or 30‹ C. below that at which it becomes plastic (between 325‹ and 450' C.), and then conveyed bodily to a retort where the coking is completed, between 500‹ and 600' C. The preheated fuel may be dropped into retorts heated up to 750‹ C. and no additional heat supplied, the exothermic reactions setting in supplying the necessary heat. Coal from a bin B is passed through a grinder C and hoisted by apparatus A from which it is discharged into a drum 11 enclosed in a heating chamber 9. The drum is heated by hot gases from the retort flues which enter and leave the chamber 9 by flues 18, 19. A hollow shaft 27 on which the drum is rotated serves as an outlet for vapours and gases. The coal after being preheated is fed to a hopper 4 communicating with the retorts, or may be charged directly into the retorts, the rate of charging being controlled, and the coking operation being continued, if desired, until metallurgical coke is obtained. The retorts may be made of iron or an alloy consisting of 50 per cent iron. 30 per cent nickel and 20 per cent chromium. The distillates are taken off through pipes 5<1>, 6<1> and passed to a recovery-plant.

Filed: 1972-02-24
Abstract: 1388892 Knitting machines UNIVERSAL MASCHINENFABRIK DR RUDOLF SCHIEBER KG 24 Feb 1972 [11 March 1971] 8586/72 Heading D1C A switch cam 1 on the carriage of a flat knitting machine is adjusted by releasing it as it approaches the adjusting device at the end of a knitting pass and, after adjusting the cam, reclamping them before a subsequent knitting pass. Block 2 carrying cam 1 is biassed by a spring 6 and is slidable in a slot 3 of cam box 4 where it is clamped by plate 5 and member 7 secured by a bolt 8 and nut 10 with lever arms 11, 11a. Cam 1 is released just before it travels onto an adjusting slide 15 or 16 by lever 11 engaging pin 13 after which the lever passes under pin 13 and slide 12 carrying pin 13 springs back so that on reversal of the carriage lever 11 engages pin 13 to reclamp the cam similarly at the opposite end of the needle bed pin (13a) on slide (12a) releases and reclamps the cam Fig. 7 (not shown). In another arrangement, clamping is effected by an eccentric lever 17 actuated by an electromagnet 18. Cam 1 may be adjusted mechanically by a slide 15 which slides in guides 21, 22 biassed against setting plates 24 on switch bar 25 which can be fine adjusted by screw spindles 26 and clamped. Bar 25 can, under the control of control cords, bring each plate 24, 24a, 24b, 24c into position for engagement by slide 15 which carries a venier scale 28. Alternatively an electrical device may be used.

Title: Electrical energy regulator
IPC: H01H37/16
Filed: 1962-03-07
Abstract: 957,873. Thermal switches. KING-SEELEY THERMOS CO. March 7, 1962 [March 8, 1961], No.8720/62. Heading H2B. In a switch arranged to regulate, by the ratio of closed to open time, the energy input to a load 10 and comprising a bimetal 24 which opens the contacts when heated by a resistance heater 33 connected with a supply through said contacts, a cam 21 being provided to vary the contact overolosure and thus to alter said ratio, the heating effect of heater 33 is altered as the ratio is altered. As shown in Fig. 1, the heater 33 is supplemented by a heating coil 26 in series with a resistor 13 whose value varies with the position of cam 21, thus increasing the heating of the bimetal 24 over the lower part of the range of the regulator. Ambient temperature compensation is provided by a second bimetal 18. In a second embodiment (Fig. 2) the switch is modified for snap action, the bimetal 51 being arranged when heated to rotate a complete switch assembly about a pivot 48, the actuating member 45 being held stationary in a position dependant upon the cam 21<SP>1</SP>. Rotation of the assembly moves a contact carrying blade spring 40 overcentre contact between 14<SP>1</SP> and 15<SP>1</SP> being broken with snap action due to a bow spring 46. The position of bimetal 51 and thus the overall range of the regulator is adjustable by screw 58. In a third embodiment (Fig. 3), the heater 126 is arranged to be periodically shorted by a second cycling bimetal 134 actuating contact 132, 133. The effect of heater 126 is thus dependant upon the closed/open ratio of this second switch, which ratio is dependant upon the position of the cam 121 by virtue of the bending of the main bimetal 124 by contact overclosure. In other suggested embodiments (not shown), the heater may be moved away from or screened from the bimetal over part of the range or the heater may be constructed of material with a high positive temperature coefficient or the heating effect may be varied by moving a reflector or heat absorbing member or by opening louvres in the housing. U.S.A. Specification 2,623,137 is referred to.

The sparking tip may be secured to one end of the silver rod e before the latter is inserted in the insulator. In a further form, Fig. 7, the silver core e is tubular and a nickel electrode c has a head g abutting on the upper end of the core ; expansion of the heated core is effected by endwise pressure. In the forms shown in Figs. 1 and 7, a seal such as f, Fig. 3, may be employed. Specification 534,248 is referred to in the Provisional Specification.
