Title: Improvements in the Combustion Chambers of Internal Combustion Engines.
Inventor: GANTHONY RICHARD
IPC: F02B25/00
Filed: 1917-05-02
Abstract: 114,685. Ganthony, R. May 2, 1917. Addition to 104,270. Cylinders, construction of.-The parent Specification describes a two-stroke-cycle engine with a combustion chamber separated from the cylinder by a valve and containing a spring-loaded scavenging piston, the movement of which is limited by a screw stop. The present invention consists in making the combustion chamber 22 surround the cylinder, and in controlling the passage between them by a sliding sleeve 19. The scavenging piston 12 is loaded by a spring 15. The stop 13a comprises a ring with a quick-threaded screw on its outer surface and teeth on its inner surface which engage a pinion on the shaft 16b by which it is turned. There are two exhaust valves 8 and 9<a> and an admission valve 9. The opening of the valve may be delayed until the piston is on its working stroke. The charge in the combustion chamber may be ignited by compressing residual products of combustion in the cylinder and admitting them to the combustion chamber at the end of the instroke.

Title: Improvements in and relating to electric motors
IPC: H02K23/64
Filed: 1928-02-29
Abstract: 311,853. Feldman, E. D. Feb. 29, 1928. Motors, controlling. - In a series-wound motor for alternative use on continuous or alternating supplies and especially of the type adapted for driving a gramophone or like machine, each of the field coils is tapped with tappings similarly spaced in the coils and an adjustable bridging arm is provided for connecting any two corresponding or adjacent tappings so that the motor can run on circuits of different voltage. In the bipolar form shown, the, field coils d, e are tapped similarly by leads f<1> - - f<5> and g<1> - - g<5> to studs h' - - h<5>, k<1> - - k<5> over which a two-armed contact can be moved so as to connect adjoining pairs of studs. The numbers of turns included between successive pairs of taps, e.g. f<1>, f<2> and f<2>, f<3> decrease. With the contact arm as shown, the whole of the turns are in circuit and the motor is adapted to run on a high-voltage circuit. For use on a lower voltage, the arm is turned counter-clockwise so as to cut out sections of the two field coils alternately until the motor runs at the proper speed on this voltage. The running speed on a given voltage may, however, be varied by altering the position of the arm. The coils d, e may be wound with a conductor of the same gauge throughout or the cross-sectional area may be varied. The invention is applicable to multipolar machines.

Filtering may be effected using a vertically disposed woven sleeve made of metal or synthetic polymer, the gas passing downwardly inside and through the sleeve and water being sprayed at the top. The gas may be obtained by roasting Mo or Cu sulphide concentrates and separating the dust.

Abstract: 1,102,021. Rotary compressors. G.G. TURNER (DAVEY COMPRESSOR CO.). Feb. 17, 1965, No. 6791/65. Heading F1F. A rotary compressor of the Roots'-blower type comprises a pair of inter-meshing rotors 13, 14 with axially-orientated rectilinear lobes or teeth 13a, 14a thereon whose profiles are such that compressible fluid, which enters a casing 10 for the rotors through a port 31, is compressed first within a space 34, Fig. 2, and subsequently in a space 35, Fig. 2a, between the meshing lobes before the fluid is ejected through one or other of a plurality of ports 37 between the lobes 14a, a further port 38 and an axial bore 25b within a fixed shaft 25 that supports the rotor 14 upon bearings (23, 24), Fig. 1 (not shown), at either end thereof, the said shaft being carried by end walls (11, 12) for the casing 10. The rotor 13 is supported by bearings (16, 17) in the walls (11, 12) and is coupled to a driving, or poweroutput, shaft (22). Synchronizing gears (18) couple the rotors to each other. Oil-mist may be injected into the casing through ports 40 that are situated on the high-pressure side of the meshing lobes. Radial sealing-strips 28 are lodged in the shaft 25 to prevent leakage of compressed fluid around the outer surface thereof. In a modification, Figs. 3 and 4 (not shown), the shaft 25 is replaced by a solid shaft or arbor (52) and the ports 37 are replaced by tapering grooves (55) in the lobes of a rotor (50), which is otherwise identical to the rotor 14, the said grooves constituting ports that in operation are periodically and sequentially brought into register with a port (54) in each end wall (53) of the casing. Alternative profiles for the lobes on the rotors are described with reference to Figs. 5 to 8 (not shown), and for details of these profiles the specification should be consulted. The numbers of lobes on the rotors may differ from that of the lobes in the embodiment shown in Figs. 2 and 2a.

Title: Echo suppressor systems
IPC: H04B3/20
Filed: 1963-02-21
Abstract: 1,027,287. Echo suppressors. WESTERN ELECTRIC CO. Inc. Feb. 21, 1963 [March 6, 1962], No. 6985/63. Heading H4R. In a system for suppressing echoes in a twoway transmission circuit employing separate incoming and outgoing paths, a variable attenuating device in the outgoing path at a terminal station is controlled by means responding differentially to the signals in both the transmission paths and a further means is connected in the incoming path responsive to the noise level in both incoming and outgoing paths to control the effectiveness of the incoming signals in influencing the differential response. Fig. 2 shows one terminal station of a system in which outgoing line 16 and incoming line 36 are connected via a hybrid 11 to a two-wire line 10 and hence to a subscriber W. A variable attenuation network 15 in the outgoing line is controlled in accordance with the difference between the signal levels WT and WR in the outgoing and incoming lines respectively. In order to prevent a loud talker at the other station blocking the outgoing transmission circuit a limiter 170 is incorporated in the incoming line, but in order that an increase in the speech level to overcome noise in the line is effective, the noise in the incoming and outgoing lines is detected in the noise-operated gain-adjusting device 220 and the level of the limiting action of limiter 170 is varied by differentially varying the attenuation of the networks 171 and 172. Signals from NOGAD 170 are also used to adjust the attenuation of networks 19 and 21 in the inputs of the differential control network 200. The attenuation network 15 in the outgoing circuit 16 preferably operates in two stages one network operating at a slow rate at low input levels and the second network at a faster rate when the input exceeds a certain higher level. The variable limiting action is obtained with the circuit shown in Fig. 4, control current from the NOGAD passing through the diodes 173 to 176 and 182 and 183, an increase in control current increasing the attenuation of network 171 by the same factor as it reduces the attenuation of network 172 and thereby increasing the effective limiting level of the limiter 170.
