IPC: F02B29/04
Filed: 1944-12-06
Abstract: 578,147. Pumps for gases. NAPIER & SON, Ltd., D., and SAMMONS, H. Dec. 6, 1944, No. 24383. [Class 7 (ii)] [Also in Group XXVI] An I.C. engine A is supplied with air compressed in two stages, a low pressure axial flow compressor M and a high-pressure centrifugal compressor E. The former is driven by a turbine J and the latter by the I.C. engine. The two shafts H, C may be connected by a clutch F. The turbine is driven by the exhaust gases of the engine which may be further energised by fuel burnt in a combustion chamber L and extra air may be supplied to this chamber from the delivery of the centrifugal compressor. The I.C. engine drives an air screw B through gearing D and the turbine drives a contra-rotating air-screw O<2> through gearing H<1>, N'. At normal speeds the clutch F is open and the turbine and I.C. engines run at their own speeds. At low speeds, the exhaust of the I.C. engine is not sufficient to make the turbine effective and a speed responsive device P closes the clutch F so that the I.C. engine drives the axial flow compressor.

Title: Electrical arrangement for rendering perceptible currents of substantially the same frequency
IPC: H04L5/06
Filed: 1927-09-16
Abstract: 284,250. Wald, M. Jan. 26, 1927, [Convention date]. Harmonic and reed telegraphs.-For multiplex wireless or wired-wireless telegraphy, use is made of a moving-coil relay, Fig. 1, of the wattmeter type, comprising a fixed coil S1 energizing an electromagnet 1 and fed from a local source 11 of constant frequency NK; and a moving coil S2 mounted in the air-gap between the magnet poles and an armature 2, and fed with signal current of frequency NS from a source 13. A mathematical analysis of the system is given to show that the indicator reed T attached to the moving coil S2 will move to close one or other of the contacts K, and so operate a local circuit containing a battery 16 and recorder 17, only when the difference between the frequencies NS and NK is less than fifteen cycles per second. 'The indicator T will not respond to any greater frequency-difference. The arrangement is such that the local circuit is constantly closed by the reed T resting on one or other of the contacts K. Taking into account the lowest signalling frequency, as determined by a minimum of at least five impulses per second to register a Morse dot, and the highest signalling frequency of 1000 cycles per second, as determined by unavoidable fluctuations in the local and signalling frequencies, the relay is stated to be capable of separating thirty different signals imposed simultaneously on a common carrier wave. In order to compensate for any phase-shift between the local and signalling frequencies, two relays R1, R2 are used as shown in Fig. 3. The coils Sl in both relays are fed from a common source 23, a choke 25 being inserted to introduce a, phase-difference of 90 degrees. The incoming signals are fed in series through the coils S2 from a transformer 13, and will actuate one or other of the reeds T1, T2 and' contacts K1, K2 if the frequency difference NS-NK is sufficiently small irrespective of phase drift. A similar pair of relays are provided in the output circuit of the demodulating valve for each signalling frequency used. Fig. 5 shows the modulating system used in transmission. Separate signalling frequencies are controlled by keys 33 in the grid of a valve 32 and modulate the common carrier wave from the oscillator 35, which may be coupled to a radiating aerial 36 or to a line wire.

Title: Improvements in or relating to apparatus for determining whether the speed of movement of a conducting or magnetic object differs from a predetermined speed
IPC: G01P1/10
Filed: 1952-10-03
Abstract: 745,357. Electric tests. GENERAL ELECTRIC CO., Ltd., DAVIS, G., and IRVING, H. D. Sept. 30, 1953 [Oct. 3, 1952], No. 24880/52. Class 37. Apparatus for determining the speed of a magnetic or conductive object comprises an H-shaped inductor 9 of the type described in Specification 729,817 having an energizing winding 11 on the cross-limb 10 and balanced secondary windings 12 on the other limbs, whereby the approach and departure of the object produces changes in E.M.F. in the windings 12, which changes are fed to a relay circuit, wherein the first change initiates the charging of a condenser 53 connected across a gas-filled discharge tube 40, and the second change will energize an alarm circuit unless the duration between the changes is sufficiently long to allow the condenser charge to reach the level required to fire the discharge tube 40 and energize a relay 41 to break the alarm circuit. As shown, the presence of a magnetic or conductive body produces an unbalance voltage in windings 12 which is fed to the grid of a valve 21 through a rectifier 20, whereby the valve ceases to conduct, and a relay 26 in the anode circuit falls to close contacts 30, energizing relay 32, whereupon condenser 53 is charged via resistors 35 or 36 and contacts 39 or 37 as selected by changeover switch 38. If the body departs from the field of the H-shaped inductor 9 before the condenser charge reaches the level required to fire tube 40, contacts 31 close to provide an energizing circuit for a relay 46 via contacts 45 and 44, the relay 46 closing a holding circuit at 48 and an alarm circuit at 47. If, however, the duration of the timing interval is sufficient to allow tube 40 to fire, relay 41 will operate to open contacts 44 and prevent relay 46 from becoming energized. Specification 745,416 also is referred to.

Abstract: 594,086. Centripetal ejector pumps. GRUSS, F. K. Dec. 12, 1944, No. 24908. [Class 110 (i)] An air-compressor suitable for a supercharger of an internal-combustion engine, comprises a rotor B having radial pockets 11 running between an outer complete housing A and an inner segmental housing C. Fresh air enters the central space of the rotor through an axial inlet in the housing A, the compressed air is obtained in the cavity 16 of the housing C, whence it is delivered by a pipe 18, and exhaust gas from the internal-combustion engine, or other energizing gas under pressure, is introduced to the chamber 25. The fresh air fills the pockets 11 and these in turn, as the rotor is rotated clockwise, pass within a closely contacting portion 20 of the housing A and then register with the housing C. The already compressed air in the cavity 16 enters the pockets and compresses the fresh air therein to its own pressure. Later, the outer ends of the pockets register with the chamber 25 and the internal-combustion engine exhaust gas (or other gas at a suitable pressure) drives the compressed air inwards into the housing C. The speed of this movement and the rotational speed of the rotor are so related that the exhaust gases do not reach the inner ends of the pockets before the latter have passed out of register with the housing C. Finally, fresh air under centrifugal force drives the exhaust gas out of the pockets into a discharge volute.
