Title: Improvements in or relating to multi-channel modulated pulse signalling systems
IPC: H04J3/06
Filed: 1947-03-11
Abstract: 622,073. Multiplex pulse signalling. LAWSON, D. I., and PYE, Ltd. March 11, 1947, No. 6730. [Class 40 (v)] In a modulated pulse multiplex signalling system, the time interval between successive groups of pulses is made greater than the interval between the pulses forming each group, this greater interval being used instead of a marker pulse to synchronize the channel separating means at the receiver. The received pulse train is applied to the integrating network C1, R1 of valve V1, and thus the potential across C2 rises to a maximum value during the long synchronizing interval. These pulses are used to trigger the synchronizing generator. Specification 581,812 is referred to.

Title: Improvements in or relating to apparatus for use in connection with the supply of feed water to steam boilers
IPC: F22D5/06
Filed: 1925-03-12
Abstract: 254,772. Myers, J. N. March 12, 1925. Fluid-actuated valves.-Feedwater is forced through a feed-heater into a gravity-feed apparatus in which the feeding pressure is maintained during charging, after which the pressure is so increased to boiler pressure as to allow the water to pass into the boiler without the increased pressure being transmitted to the feed heater. The apparatus consists of a cylinder A, Fig. 2, containing a steam tight piston B below which the feed is admitted through a pipe G and having pipes connected to its upper part for admitting and exhausting boiler steam through a pressure operated valve C. A spring loaded or like valve K in the steam exhaust pipe K<1> maintains a uniform back pressure in the cylinder while it is being supplied with fresh feed. A check valve prevents the boiler pressure from being transmitted to the feed heater and other auxiliaries. The sliding valve C, Figs. 4 and 6, is operated by boiler steam admitted to the top of a piston D' on the valve under the control of a pilot valve F operated by projections B<3> on a rod attached to the piston B. The projections engage in openings in a frame attached to the pilot valve and cause the valve to so slide backwards and forwards as to control ports allowing boiler steam to pass through passages C'. C<8> to the back of the piston D<1> or to exhaust through the passage C<8> and a pipe E<7>. Ports C<4> in the lining of the valve C place a pipe A<7> opening into the top of the cylinder A in communication with the exhaust pipe K<1> in the upper position of the valve, and with the steam admission pipe I<1> in the lower position of the valve. The piston B, the valve C and the pilot valve are formed or provided with rustless steel surfaces and work in rustless steel liners.

Title: Improvements in or relating to elastic fluid compressors
Inventor: CARTER ALFRED DENIS SNOWDON
IPC: F04D29/32
Filed: 1951-03-22
Abstract: 704,682. Axial-flow compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 21, 1952 [March 22, 1931], No. 6976/51. Drawings to Specification. Class 110 (1) In an axial-flow compressor having aerofoil blades, the blades of the first row have a transverse section in the region of their mid-length in which the point of maximum camber or the point of maximum thickness, of both, is or are each disposed at a percentage of the chord of the section from its leading edge 'which is greater than the corresponding value for the blades of the last row. The purpose is to prevent stalling in the initial stages or choking in the later stages under part load conditions. Preferably, the variation from row to row through the compressor of the percentage distance from the leading edge of the point of maximum thickness occurs more rapidly in the later than in the earlier stages, and vice versa in the case of the point of maximum camber. For convenience in manufacture, the variation may be accommodated in a small number of steps. Thus, in a compressor comprising ten rows of blades, for the point of maximum thickness, the percentage distance may be 40 for the first six rows, 35 for the seventh and eighth rows and 30 for the ninth and tenth rows, while for the point of maximum camber, the percentage distance may be 50 for the first two rows, 45 for the third and fourth rows and 40 for the remaining rows. The theoretical considerations underlying the invention are set forth in the Specification

Abstract: 512,630. Party-line systems. SIEMENS & HALSKE AKT.-GES. March 8, 1938, No. 7302. Convention date, March 8, 1937. ;[Class 40 (iv)] The bells in a direct-call party-line system are rung selectively with the aid of switches driven by synchronous motors fed from. a common source. Arrangements are made for calling all stations when a conference is desired. Means may be provided to prevent interference by other parties during the selecting operation. As shown, a calling' subscriber sets his switch WT to the number of the wanted subscriber or, in the case of conference calls, to his own number, and operates key RT to connect the supply to the wipers of WT and, over normal terminals of the synchronous motor switch Dm, to the line. Relays R at the home and distant stations pull up to connect the source of supply to the motors which are kept running over off-normal wipers dmd. When the switches are in the position marked by the calling party's switch WT, supply current is sent to line and is received by the wanted party's, bell Wk. In the case of conference calls; the power current is sent to the line at the calling station independently of switch Dm, and all the bells respond in return. In a modified arrangement the bells ring simultaneously. The circuits over the off-normal wipers ensure that the switches start in step. Arrangements may be made to restore WT automatically when the receiver is replaced. In a modification Fig. 1 (not shown), the switches Dm are always running, and conference calls are initiated by operating RT to a special position without setting WT. In a further modification, Fig. 3 (not shown), the switch motors run continuously but the wipers are normally stationary and are coupled to the motors under control of relays connected similarly to the relays R. The switches WT may be replaced by groups of keys, several of which may be actuated at once.
