Title: Improvements in or relating to wireless signalling systems
IPC: H04B1/12
Filed: 1931-12-23
Abstract: 391,254. Wireless receiving systems ; multiplex wireless signalling. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 23, 1931, No. 35615. Convention date, Dec. 23, 1930. [Class 40 (v).] Relates to wireless systems in which the effects of atmospherics are reduced, and comprises means for making a visual or an electrical comparison between the disturbances and signals received on the signalling channel and the disturbances received on a neighbouring channel. In one arrangement, the transmitter S, Fig. 1, uses a note-frequency produced by G1 and keyed at T, the carrier frequency being generated at G2, and at the receiver the rectifier Glo feeds filters K1, K2, the former passing the signal frequency band and the latter a neighbouring band in which disturbances only appear, to be rectified at Gl3 and recorded at A2. A further rectifier Gl2 in this channel controls the gain of the amplifier RV in the signal channel according to the strength of disturbances, the signals passing to a rectifier Gl1 and recorder A1. The two records may be compared, and if several receivers are used or repeated transmission of the same signal for example with different note frequencies is employed, all the signal amplifiers may act on a common recorder. An arrangement of this nature adapted to transmit telephony and telegraphy simultaneously comprises at the transmitter a microphone MK, Fig. 2, and two note frequency generators G1, G2, the frequencies of which are changed, for example from 2700 and 5550 respectively to 2800 and 5650 respectively by keys T1, T2 co-operating with condensers C, filters K1, K2, K3 being interposed between these three generators and the modulator M and all passing different frequency bands. At the receiver, a series of filters K4 .. K11 follow the rectifier Glo, the telephony signals being taken from the output of filter K6, filters K8, K9 serving to separate frequencies 5550 and 5650 which after rectification at Gl3, Gl4 energize windings w3, w4 of relay Rel, while filters K10, K11 separate frequencies 2700, 2800 which after rectification at Gl5, Gl6 energize windings w5, w6 of the same relay. Relay arrangements R2, R3 and R4, R5 operate to short-circuit the 5650 frequency channel when the 5550 channel is operating and vice versa, and the 2700 channel when the 2800 channel is operating and vice versa. Thus the 2700/2800 channel may be rendered entirely inoperative by interference but the 5550/5650 channel may still be operating and vice versa. If both channels are disturbed the relays R2 .. R5 may be arranged to switch off the recorder. If the windings w3, w4 and the windings w5, w6 of relay Re1 are arranged in opposition, relays R2 .. R5 may be dimensioned to respond only above a certain amplitude. The effects of smaller disturbances are cancelled out in the relay Rel. With repeated signal transmissions a lower recording strength may be given to disturbed signals than to undisturbed signals. Specification 198,428, [Class 40 (v), Wireless signalling &c.], is referred to.

Title: Process for the metallization of textile surfaces by the vapour-deposition of metals in a vacuum
IPC: C23C14/20
Filed: 1962-09-21
Abstract: A metallized surface is produced on a textile material by treating it with a dispersion or emulsion of a self-cross-linking acrylic or methacrylic acid ester co-polymer, drying the impregnated material at a temperature below the cross-linking temperature of the co-polymer, e.g. at 110  DEG C., vapour depositing metal such as aluminium on the layer in a high vacuum, and heating e.g. by infra-red heaters the material until cross-linking of the co-polymer occurs.  The material may be calendered at the cross-linking temperature e.g. 140-160  DEG C. immediately after drying, or subjected to embossing.  Copolymers derived from an acrylic ester and a methylol-group containing acrylic amide or an epoxy-group are preferred, and may be applied by screen printing. Examples of textile materials treated are polyester, polyamide and cotton fabrics.  Dispersions are disclosed containing melamine-formaldehyde initial condensate and ZnCl2 or amino nitrate for initially foularding the fabric.

Abstract: 1,076,999. Superheating steam. COMBUSTION ENGINEERING Inc. Sept. 3, 1964 [Sept. 20, 1963], No. 36226/64. Heading F4A. [Also in Division F1] A steam turbine plant comprises in flow series a steam generator 16, main control valve 20 and turbine stages 22, 26, 28, a reheater 24 being disposed between stages 22, 26. The condensate is pumped from a condenser 2 through feedwater heaters 6, 12 and a deaerator 8 back to generator 16. For restarting while the turbine casings are still hot, valve 20 is closed and high temperature and pressure steam from generator 16 flows through branch pipe 32 to the high pressure side of a heat exchanger 34. The steam then passes through a throttle valve 36 and enters a flash tank 38 at reduced pressure, any water collected in tank 38 being returned to condenser 2 through pipe 42. Some of the throttled steam passes through valve 48 to the low pressure side of heat exchanger 34 to be heated by the high pressure steam from pipe 32, the heated steam leaving the heat exchanger through pipe 49 to enter turbine 22. Since this steam is at high temperature the thermal gradients across the turbine casings are reduced. Throttled steam not flowing to heat exchanger 34 flows through pipe 44 to de-aerator 8 or condenser 2. In a modification, Fig. 2 (not shown), the heat exchanger is in the main steam pipe 18. The arrangement of heat exchanger and throttle valve is applicable also to a gas turbine plant.

Title: An electrical drive for knitting machines
IPC: D04B15/99
Filed: 1928-12-08
Abstract: 302,160. Siemens - Schuckertwerke Akt.-Ges. Dec. 10, 1927, [Convention date]. Alternating-current motors. - Multi-speed induction motors for driving knitting machines are provided, in addition to the stator and slip-ring rotor windings for giving the normal working speeds, with at least two further pole-changing windings on both, the stator and rotor, or the connections of a smaller number of windings may be variable whereby at least two different lower speeds may be obtained, for example for narrowing and plating. Two methods of carrying out the invention are described. Fig. 1 shows one method in which the stator windings 1, 2, 3 have different pole-numbers in the ratio of 2:3:4, for example. The rotor has three corresponding windings 11, 12, 13; the 2n-pole winding 11 is connected to slip-rings 21 for adjusting the working speed while the windings 12, 13 of higher pole-numbers are short-circuited on themselves. In the second method, Fig. 2, the stator carries a combined winding 31 which when fed with current at the points 41, 42, 43 works as a 2n-pole winding but when fed at the points 44, 45, 46 works as a 4n-pole winding. The stator carries in addition a 3n-pole winding 32 which is fed at the points 47, 48, 49. The rotor carries two windings 51, 52. The winding 51 serves as a slip-ring winding when the stator is excited with the lowest number of poles and as a short-circuited winding when the stator is excited with its highest pole-number. The second rotor winding 52 is a short-circuited winding cooperating with the stator winding 32. The motors may be arranged so that the lower speeds may be adjustable.
