Title: Separation process using zeolite a with properties
IPC: B01J20/18
Filed: 1974-06-06
Abstract: 1456418 Separating gases BAYER AG 6 June 1974 [7 June 1973] 25200/74 Heading BIL [Also in Division C1] Polar or Polarisable substances are separated from less polar or less polarisable substances by use of a type A zeolite of formula: xMe<SP>II</SP>O.nMe<SP>I</SP> 2 O.Al 2 O 3 .(1.85 Œ 0.50)SiO 2  wherein Me<SP>I</SP> is a monovalent metal (e.g. Na) Me<SP>II</SP> is a divalent metal (e.g. Ca), x = 0.80-1.20 n = (0.8-1.2) - x. In the examples the zeolite is used for the enrichment of oxygen from air at room temperature and for 'the removal of traces of CO 2  from air. The capacity of the zeolite for the former process was measured in the figured apparatus, where (1) denotes the test tube (3) denotes a vacuum pump and (4) denotes a gas meter monitoring the output of the gas from (3); dried compressed air is supplied via pipe (5) through a reducing valve (6) and a buffer vessel (8) to test tube (1). The adsorption pressure is precision adjusted to 20 mm Hg through the height of the column of liquid in the "immersion vessel" (11). The outlet end of the test tube 1 may be connected via shutoff valves (12a), (13a), (13b) and (13c) to calibrated gasometers (14a), (14b) and (14c). Alternatively the gas flowing from the test tube (1) may be diverted via shut-off valve (12b) to a gas meter 15. The pressure prevailing at the outlet end of the test tube is measured via mercury manometer 16. The adsorption-desorption cycle consists of the phases (A) evacuation, (B) filling to the adsorption pressure (C) passing air through (1) until the zeolite until the gas meter (15) indicates a specified gas output. This cycle is repeated until the volume of gas pumped off during (A) is constant as measured by gas meter (4). In the third phase of a cycle, the gas issuing from (1) is passed into the gasometer (14a) until a predetermined quantity of gas has been collected. Thereafter the gas stream is diverted to e.g. gasometer 14(b) where another predetermined sample is collected. The collected samples are then analysed for their O 2  content.

Title: Improvements in or relating to electric phase equalising networks
IPC: H03H11/18
Filed: 1957-08-09
Abstract: 825,191. Signal delaying systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 9, 1957 [Aug. 16, 1956], No. 25264/57. Class 40 (4). [Also in Groups XL (b) and XL (c)] A four-terminal network having an attenuation or gain which is independent of frequency but a frequency-dependent phase-shift, comprises two transmission paths connected in parallel, the first path comprising a reactive circuit which is resonant at one or more frequencies and the second path having an attenuation or gain which is independent of frequency, the transmission characteristics of the first path being such that it may be represented by a circle diagram on a resistance-reactance diagram and the output voltages from the two paths being arranged to act in opposition with that from the first path having at the resonant frequency of that path an amplitude twice that from the second path. In a first embodiment, Fig. 1, the first path comprises amplifying valves 1, 2 and a reactance network LC in parallel with the resistance R connected in the anode circuit of the valve 1. The second path comprises a valve 3, the two paths being connected in parallel and having a common output load r. The resistance R is so chosen in relation to the mutual conductances of the valves 1, 2, 3, that at parallel resonance of the circuit LC the potential developed across the resistance r due to the signal transmitted by the first path is twice that developed across the same resistance due to the signal passed by the second path. The reactive circuit LC may be replaced by other forms of reactive circuit, such as for example a length of loss-free cable having a variable capacitor connected across its free end. In order to ensure that the signals delivered by the valves 2, 3 are in precise anti-phase at resonance it may be necessary to introduce a delay into the second path; this may be constituted by the grid lead inductance of the valve 3 and its grid cathode capacitance together with a further suitable resistor (not shown). In a second embodiment, Fig. 3, the first path comprises valve 1 having a series reactive network connected in its cathode circuit and the second path comprises a valve 3 connected reversely to the input terminals ag1 and having a resistor R2 connected in its cathode circuit. The circuit parameters are so chosen that the signal developed across resistor r in the anode circuit of the valves 1, 3 due to the signal transmitted by the first path is at resonance twice that due to the signal transmitted by the second path.

Title: Improvements in or relating to elevator systems
IPC: B66B1/08
Filed: 1945-10-03
Abstract: 601,491. Motor control systems. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 3, 1945, No. 25705. Convention date, Oct. 4, 1944. [Class 38 (iii)] Braking systems.-A lift system, with a magnet coil for holding off a spring-applied brake and a discharge resistance which is connected across the brake coil when, as the lift car approaches a floor, the supply to the driving motor and brake coil is cut off, includes means responsive to the speed of the motor for adjusting the value of the discharge resistance according to the load in the car and the direction of travel, whereby the application of the brake will be delayed to a point which will cause the car to be stopped approximately level with the floor. In Fig. 2, the car switch C5 energizes the Up switch U, or the Down switch D, and the running relay M to close associated contacts M1-M4, and U1, U2, U4 of D1, D2, D4 in the circuits of the motor windings 11-12-13 and the brake coil BC. This coil-has two discharge resistances R6 and R1-5, of which the higher (R6) is permanently connected across the coil. A tachometer generator GA driven by the motor and having a separately-excited field GF, a shunt field GFE and a series field GFS is connected to the load relays 1H-4H by contacts U5-U8 or D5-D6 with a polarity independent of the direction of rotation. After about 2 seconds, this generator is disconnected by contacts T1 and T2 of the timing relay T which was deenergized by relay M. According to the speed reached in this time, the voltage of generator GA can lift one or more of the relays 1H-4H successively, each of which prepares a circuit for, the next through contacts 1H2-3H2 and energizes one of the resistor relays 1X-4X which latter maintain themselves and open a short-circuit across part of the lower discharge resistance R1-R5, now disconnected by contacts M5. When the car switch is released, it energizes the coil S of the inductor switch on the car which, at a certain distance from a floor, opens its contacts S1 to de-energize switches U or D and .M so that the supply to the, motor. and to brake. coil BC is cut off. Resistance R6 prevents immediate application of the brake. Contacts M5 connect across coil BC a part of resistance R1-R5 dependent on how many relays 1X-4X were actuated ; the application of the brake is delayed longer, the less the motor speed, so that the brake is applied at a point at which it will bring the car to rest approximately at floor level. After about a ¢ second, the timing relay F, de-energized by the opening of contacts M7, opens the circuit of relays 1X-4X.
