Abstract: 455,301. Two-stroke engines. CREMER, C. L., Archibald Road, Glen Eden, Auckland, New Zealand. Jan. 13, 1936, No. 1065. [Class 7 (ii)] The outer piston 2 is formed with a tubular extension beyond the combustion chamber 23 ; this extension 2a is provided with ports 12 through which mixture is transferred to the combustion chamber from the pump space between the inner and outer pistons. A rod 11 carried by the inner piston carries the mixturecontrol piston valve 10, mixture being drawn into the pump space from the supply pipe 7 through ports 8, 10a. The inner piston is connected by a rod 19 to an eccentric 20 on the crank-pin to which the rods 17 from the outer piston are connected. The rod 19 passes through a slotted gudgeon pin 14 retained in the outer piston by pins 14a driven through bosses 15 which move in slots in the cylinder. The pins 14a are locked by grub-screws 15a, and the gudgeon 14 prevented from turning by end projec. tions and recesses 24.

Indicating.-In apparatus for indicating &c. at a distance the sum of a series of movements, in which a potentiometer coil is provided for each movement, all the potentiometers are supplied in series by one source of current and the current is kept constant by providing with each of the potentiometers, except that furthest from the source, a compensating coil over which a sliding contact moves simultaneously with the potentiometer contact. As shown in Fig. 1, a number of " Lea " water recorders control the movement of arms d carrying contacts c<1> - - 0'. In series with a source of current f are arranged potentiometer coils a<1>, a<2>, a<3> and compensating coils b<1>, b<2>. The sum of the movements is indicated by a voltmeter e. Recording and registering instruments may be placed in parallel with the voltmeter e. Separate voltmeters g may be provided for each of the instruments. In another arrangement the rods d are operated by a section of a furnace door or, in the case of a fixed aperture by the mechanism controlling the rate of feed, to indicate the rate at which fuel is being consumed by a number of furnaces. An additional variable resistance n is provided in series with the voltmeter for purposes of calibration. The invention is also applicable similarly to apparatus for conveying grain &c.

Filed: 1955-01-19
Abstract: 807,156. Axial-flow pumps and compressors. BAEZ, G. F. Jan. 19, 1955, No. 1647/55. Class 110 (1). A compressor or pump comprises a casing having no stationary guide vanes for the fluid and containing two bladed rotors which are rotated by a motor in opposite directions at the same speed, the shaft of one rotor extending within the hollow shaft of the other rotor. The input shaft 7, Fig. 1, which is driven directly or through reduction gearing by a motor (not shown), drives a hollow shaft 11 through pinions 9 and 10. Pinion 9 also meshes with an idler pinion (not shown) which in turn meshes with a pinion 13 on a shaft 14 which extends through the hollow shaft 11. By this means, a rotor 30 carried by the shaft 11 and a rotor 31 carried by the shaft 14 are rotated at the same speed but in opposite directions. The helical rotor blading 41, 40 conveys the liquid or gas from an inlet 5 to an annular chamber 27 and thence through a helical passage 27a to a lateral discharge passage 25. Each rotor may be recessed as at 43, Fig. 5, to accommodate a shaft seal comprising a rubber washer 44 pressed by a spring 42 against a ring 45 fixed to the rotor shaft and bearing against a stationary ring 47. Specification 675,948 is referred to.

Title: Improved Method of and Apparatus for Preparing Cold Crimp Sleeves

Abstract: 1,187,754. Two-part couplings. AMP Inc. 10 Jan., 1969 [26 Feb., 1968], No. 1720/69. Heading H2E. In a method of preparing insulating sleeve lengths for cold crimping about wire terminations wherein a continuous length of sleeve material is fed to a cutting and measuring station where an end length is severed from the continuous length, said end length is also deformed at this station before the cut length is transferred laterally from the station. This process is carried out in a machine similar to that described in Specification 1,181,770 but wherein a deforming die 41, Fig. 5, connected via a spring- loaded push-rod 42, a rocker arm 45, and a thrust rod 46 to the ram 11 is thus operable simultaneously with the blade 14 to form a recess 8, Fig. 4, in the severed sleeve length. The operating length of the thrust rod 46 is adjustable to enable the depth of the recess 8 in the sleeve to be determined. Insulated connectors made with such deformed sleeves prevent the incorrect insertion of a connecting tab (not shown) between the base portion of the wire termination 1 and the insulating sleeve which may occur when using non-deformed sleeves as described in Specification 1,181,770.

Abstract: 562,049. Navigational instruments. POLE, J. S., GLENNY, A. P., and SPERRY GYROSCOPE CO., Ltd. Feb. 3, 1943, No. 1768. [Class 97 (ii)] In a compass repeater, the pointer, which is controlled from the controlling compass, is arranged to lie centrally on the dial and to move, when the craft turns, in the same direction to indicate the heading of the craft and the dial is also arranged whereby the relatively stationary compass card may be turned to indicate the desired set course against a fixed lubber mark, the pointer being also brought into alignment with such lubber mark. The pointer 39 is fixed on a card 38 which is cut away as shown in Fig. 1 to expose the compass card 41 having bearings marked thereon. This pointer and card 38 is arranged to follow the movements of the controlling compass by means of the repeater motor housed in the casing 7, gearing 11, 13, 21 and 23, differential gearing 25 and gears 27, 37. The bearing to be set on the compass card 41 is brought about by rotation of the compass card until the desired bearing shows against a lubber mark 57, the rotation being made by gears 51, 49, 47 and knob 55 and shaft 53. Adjustment of the pointer 39 relatively to the repeater motor is caused by operating the gears through a spring clutch, part of which comprises a spindle 73 which projects through the casing and is rotated by a key inserted in the square aperture 75. The window of the dial is provided with parallel lines 61 to facilitate detection of any movement of the pointer 39.
