Title: An improved return signalling device for remote control installations controlling alarm apparatus
IPC: H04M11/04
Filed: 1938-02-16
Abstract: 499,442. Electric signalling systems. LANDIS & GYR AKT.-GES. Feb. 16, 1938, No. 4856. Convention date, Feb. 25, 1937. [Class 40 (i)] In an alarm system comprising an alarm transmitting station and a central station connected to alarm receiving stations by a network which may be the telephone network, a return checking signal is sent by an operated alarm device over synchronously driven switches at the central and transmitting station. In the system shown, the alarm transmitter G is connected over a pilot line l1, l2 to central alarm selecting apparatus Z which disconnects a telephone subscriber's line l3, l4 from the normal line circuit l5, l6 and connects it to the pilot line as for example in the system described in Specification 498,563. When the alarm E at the substation has been operated, it closes contact e1 in the return signal circuit. The operation of transmitter G closes contact g1 so that synchronous motors S1, S2 at the transmitting and central stations drive selectors K1, K2 relays Ra, Rb being operated over off-normal contacts n1, n2 which also maintain the motor circuits. When the selectors reach contacts of the selected subscriber's line contact e1 if operated closes a simplex circuit over the subscriber's line and selector K2 to pilot wire l1, l2 whereupon the corresponding relay W and lamp M are operated over selector K1, relay W being held over contact g1 closed by the transmitter. The simplex circuit may extend also over the pilot line and the return signal may be an A.C. or D.C. signal.

Abstract: 1,130,329. Reactors. BABCOCK & WILCOX Ltd. 4 Feb., 1966 [24 Feb., 1965], No. 5118/66. Heading G6C. An integral gas-cooled nuclear reactor has a core 3 and a vapour generating heat-exchanger 5 arranged within a pressure vessel 2, and a coolant gas space including means defining a path through which the coolant gas flows successively through the core 3 and the heatexchanger 5, the wall of the pressure vessel 2 being included in the boundary of the gas space and lined internally by cooling tubes 18 connected to the heat-exchanger 5 so that water flows in sequence through the cooling tubes 18 and the heat-exchanger 5. The heat-exchanger 5 and the core 3 are separated by a cylindrical biological shield 4. The vessel 2 is fabricated from metal plate and has cooling water tubes 7 welded to its outer surface. These tubes 7 are cooled by the passage through them of condensate from a turbine driven by steam generated in the heat-exchanger 5. The vessel 2 is insulated on its inner surface by a layer 8 of corrugated stainless steel plates and is encased in a concrete shell 9. The heat-exchanger 5 consists of tubes lying in planes extending radially from the vessel centre and each is formed of horizontal tube lengths connected together by return bends. Inlet and outlet feed branches 11, 12 are provided for the heatexchanger 5, the former being connected to the heat-exchanger 5 by the tubes 18 which form an internal tube lining of the vessel 2. A thermal shielding 19 located at the upper end of the vessel 2 comprises a covering 20 of heat-resisting steel lined on the underside with hollow metal castings 21 filled with refractory insulating material. Circulating fans 13 are mounted at the ends of ducts 27 connected to a plenum chamber 6 beneath the core 3, gas being withdrawn from the heat-exchanger 5 along the passages containing the fans 13 and then passed along the ducts 27 to the plenum chamber 6. From the plenum chamber 6 the gas passes upwardly through the core 3, then over the edge of the shield 4 and downwardly over the heatexchanger 5. Water fed into the inlet branches 11 passes along the tubes 18 and cools the vessel 2, before being converted into steam in the heat-exchanger 5 and passed through the outlet branches 12 to the steam turbine.

Abstract: 814,498. Catamenial appliances. WILSON, S. Feb. 14, 1958 [Feb. 18, 1957], No. 5369/57 Class 81 (2). A sanitary pad has a former 10 of foamed synthetic resin with surface layers 11, 12 of tissue, lint or similar absorbent material. The whole pad is enclosed in a gauze wrapper 13 in the normal manner. The use of such a former prevents the pad folding and creasing in use but retains sufficient resilience to ensure comfort. In one modified form of pad the foam former is slightly narrower than the finished pad and is completely enclosed in absorbent material while in a third form it is displaced towards one face of the pad so as to give an increased thickness of absorbent material on the side next to the wearer.

Title: Improvements relating to the conversion of electric currents
IPC: H01T11/00
Filed: 1932-02-23
Abstract: 400,934. Spark-gap apparatus. MARX, E., 3, Rankestrasse, Brunswick, Germany. Feb. 23, 1932, No. 5412. Convention date, Feb. 23, 1931. [Class 40 (v).] Relates to spark-gap apparatus, suitable for converting direct into alternating current, or vice versa, of the' kind in which the electrodes are enclosed in a chamber filled with gas under pressure. According to the invention, compressed gas enters the chamber through an opening N and flows out through openings in the electrodes P, Q which are of convergent- .divergent shape, as shown. The arc is thereby lengthened to an unusual extent and is ruptured with certainty. For converting direct into alternating current the action is started in each phase by timed transient voltages, and is extinguished by the reversal of the potentialgradient through the supply transformers. The supply of air may be given a spiral movement, and in the event of severe over-currents or short-circuits the pressure is rapidly increased from an auxiliary supply. In a modified arrangement, one electrode is shaped to present an acute bend at the arcing-tip whilst the second electrode is flat. Intensive cooling of the electrodes may be effected by rapid expansion of the compressed gas in the chamber ; or saturated steam can be used. Cooling-fluid is supplied to the electrodes through pipes U and leaves through pipes V. The Specification as open to inspection under Sect. 91 contains a detailed description of the modified arrangement described above, in which the compressed-air supply is fed coaxially with the flat electrode. This subject-matter is not contained in the Specification as accepted.

Abstract: 782,384. Substation equipment. WESTERN ELECTRIC CO., Inc. Feb. 24, 1956 [March 11, 1955], No. 5845/56. Drawings to Specification. Class 40 (4). In a phonographic call-answering apparatus, the arrival of an incoming call starts the driving means for the record carrier which after a predetermined interval operates switch means which in turn places the driving means, after a further predetermined interval, under the control of a device which stops the driving means when the calling party is disconnected. In the embodiment described, ringing current brings about in known fashion the operation, after a delay while the resistance of a thermistor is sufficiently decreased, of a relay which starts the movement of the record carrier and pick-up. These, after a predetermined time, operate switches which bring up a second relay. This connects across the line both the pick-up, to send the recorded message to the calling party, and a third relay, causing the line connections. to be transferred at the exchange from ringing battery to talking battery. The second relay also causes the operation, after a delay while a condenser is charged, of a fourth relay which places the holding circuit of the first relay, and hence the driving means, under the control of the third relay, which holds in the line loop. The delay in the transfer of control prevents the premature release of the apparatus by a possible momentary relapse of the third relay when ringing battery is replaced by talking battery.
