Title: Improvements in electro-mechanical gearings for vehicles and so forth
IPC: F16H61/02
Filed: 1951-07-27
Abstract: 711,064. Transmitting mechanical power. AKERMAN, O., and AKERMAN, L. O. July 27, 1951 [July 31, 1950], No. 17906/51. Drawings to Specification. Class 38(4) Relate to a variable-speed electromechanical power transmission system, particularly for vehicles, of the kind wherein the three elements of an epicyclic gear are coupled, respectively, to primemover, the load and a dynamo-electric machine, the last of which is electrically connected to a similar machine coupled to one of the other two elements of the gear and wherein the first machine has fixed separate excitation and the second a reversible separate excitation. According to the invention, the system is such that (1) with the first machine stalled and the prime-mover running at normal speed, the load shaft runs at a medium speed which is considerably higher than half of the continuous speed range afforded by the electric machines; (2) during starting, the prime-mover is accelerated to normal speed from an initial speed which is at least as low as half said continuous speed range and preferably lower than half normal speed of the prime-mover; and (3) the first electric machine is so coupled to its element of the gear as to be capable of causing therein a reactional torque moment (preferably near maximum speed of the machine) equal to the torque moment produced therein by the primemover. A shiftable step gear providing steps equal to the said continuous speed range, may be inserted the output member of the epicyclic gear and the load shaft.

Title: A circuit for the simultaneous amplification of a frequency band and of a signal frequency outside the said band
IPC: H04Q1/442
Filed: 1955-06-21
Abstract: 803,662. Voice-frequency signalling. FELTEN & GUILLEAUME FERNMELDEANLAGEN G.m.b.H. June 21, 1955 [June 21, 1954], No. 17937/55. Class 40 (4). In a circuit arrangement for the simultaneous amplification of a signal of frequency band F and a signal f outside the band, a (frequency dependent) network 1 is arranged in the input circuit of the amplifier or in a feedback path whereby the level of signal f is relatively elevated above the level of band F and the distortions of band F occurring in the transmission path and in the output filters are compensated. The band, in this case a speech band, is attenuated by three nÚpers in the network and the signalling frequency in the output of valve 2 is selected by a resonant circuit 3 to actuate relay 4. The signalling frequency is blocked from the speech output path by a filter 6 which may be high-pass or low-pass according to the position of the signalling frequency relative to the band. The arrangement, Fig. 2 (not shown) includes a band elimination filter in the output path. A further modification, Fig. 3, which includes the band elimination arrangement of Fig. 2, has a network 12 in the feedback path of valve 2 in lieu of network 1. The network 12 which is of high impedance is also shaped to effect equalization and to compensate for edge distortion arising from the filter. In a further modification, Fig. 4 (not shown), the network is incorporated in the current feedback loop.

Abstract: 577,357. Coating by spraying. AKTIEBOLAGET ECCOVERKEN. Nov. 1, 1943, No. 18056. Convention date, Oct. 31, 1942. [Class 69 (iii)] In spraying surfaces with paint, varnish, molten metal, &c., the shape of the crosssection of the issuing paint spray can be varied by suction induced by high velocity airstreams A suitably and adjustably directted. For example, the elliptical cross-section I, Fig. 3, of a paint spray issuing from a slot nozzle 10 can be elongated to the cross-section II by top and bottom streams of air issuing from between surfaces 11 and 13 and over a directing surface 12. In Fig. 1, the paint &c. is supplied through a conduit 2 and is sprayed through a slot or circle 10 by air or gas from a conduit 5. The spray-shaping air or gas from conduit 8 passes to a jet nozzle 7 and issues through openings between the surfaces 11, 12 and 13, the surfaces 11, 12 being axially movable in relation to 13 to vary the opening and spread of the air jets which effect the shape of the paint spray. The paint spray may also be shaped by variation of the pressure of the shaping air alone. The conduits are provided with pressure equalisers or strainers 6 and 9. Specifications 529,316 and 563,174 are referred to.

Title: Pressure testing
IPC: G01M3/32
Filed: 1971-05-28
Abstract: 1386239 Pressure gauges; leak testing UNITED GAS INDUSTRIES Ltd 1 May 1972 [28 May 1971] 18104/71 Headings GIL GIR and GIS The liquid reservoirs 6 of a plurality of monometers are inter-connectable by the opening of valves 3, and hence when subjected to a common reference pressure the liquid levels in the manometer tubes 1 attain a common level to which a cursor 7 may be set. When the valves 3 are then shut and pressure sources connected to each of the reservoirs via inlet ports 2, a variation in the pressure of one source is detected by a change of liquid level in its associated tube 1. The pressure sources may be pressurized vessels, e.g. gas meters 15 pressurized at the reference pressure by a common source 10, a fall in liquid level in one tube 1 thus indicating a leak in a vessel. Alternatively to detect leakage into a vessel the vessel is placed in a pressurized compartment and the compartment connected to a manometer. Errors due to irregularities in the internal dimensions of the tubes 1 are thus eliminated and temperature changes can be compensated for simply by moving the cursor 7. In addition the tubes 1 can be inclined, e.g. by 30 degrees, to increase the sensitivity and resolution of the manometers.

Abstract: 561,389. Automatic regulation. SIEMENS BROS. & CO., Ltd., ROSEN, A., and ARCUS.' G. W. Dec. 31, 1942, No. 18568. [Class 38 (iv)] A d.c. voltage is stabilized by a screen-grid thermionic valve in series between a source and the load circuit, a constant voltage device or devices, such as neon tubes, being connected in one or more shunt circuits. As shown, the valve T11 has its screen grid connected to a point between two of a number of neon tubes T1 to T10 in a shunt circuit from a point between two resistances R1, R2 in series with the valve, so that by adjusting the resistance R1 the potential of the control grid may be biassed to overcome the tendency of the screen grid to change the conductivity of the valve when the source voltage changes. The constant current through the valve may be varied by adjusting the resistance R2. A second shunt circuit of neon tubes T12 to T20 may be connected after the valve and the load circuit may be variably tapped across these. A network comprising more than two series resistances or constant current devices with a like number of shunt circuits may be used, but the thermionic valve is preferably the last of the series. To prevent overload on this valve, a relay operated by a coil R in series with one or more neon tubes and in parallel with the valve may be adapted to disconnect the load circuit. A ballast resistance BR prevents change in the cathode heating current.
