Title: Improvements in gas or vapour adsorption apparatus using solid adsorbents
Inventor: GREGORY SYDNEY ABSELL
IPC: B01D53/04
Filed: 1960-11-09
Abstract: 992,061. Adsorbent reactivation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 12, 1961 [Nov. 9, 1960], No. 38501/60. Heading B1L. The invention comprises a method of reactivating adsorption apparatus of the kind using solid adsorbents to separate vapours or gases from gaseous mixtures and in which adsorbent reactivation is effected by alternately heating and cooling the adsorbent and employing a purge gas, wherein the purge gas is vented under pressure so as to induce a cooling flow of atmospheric air, and apparatus for effecting this wherein the cooling air may be blown over the surface of an adsorption vessel or vessels, or passed through pipes embedded in the adsorbent and having heat transfer surfaces in contact with the adsorbent. Exemplified apparatus is shown in Fig. 4, wherein vessels A and B are arranged for alternate treatment of process gas and reactivation. Process gas flows from inlet I through valve V and, in the example shown, through vessel B to valve 30, where some of the gas is tapped off for use as a purge gas for vessel A, passing after such use by line IV to be emitted through injector nozzle 21, causing an induced flow of atmospheric air into plenum chamber 20 and through the appropriate valve 17. If desired both valves 17 may be opened. The cooling tubes in the adsorbent are preferably inverted-U tubes having heat-exchange fins on one limb and adapted for electrical or steam heating. The apparatus illustrated may form part of a battery of such vessels, and the control operations may be automatic. The invention may be used to separate water vapour from air and carbon dioxide from mixtures containing carbon dioxide and nitrogen. Molecular sieve adsorbents may be used. Specifications 986,792, 990,228, 990,229, 990,230 and 992,062 are referred to.

Title: Improvements in or relating to high frequency amplifiers
Inventor: WATSON PETER ANTHONY
IPC: H03F7/00
Filed: 1969-08-01
Abstract: 1,256,032. Parametric amplifiers and digital transmission systems. POST OFFICE. 28 July, 1970 [1 Aug., 1969], No. 38712/69. Headings H3B and H4P. In a phase locked degenerate parametric amplifying device, the pump signal is twice the frequency of the input signal and is phase locked thereto. In Fig. 1, an input microwave port 8 is connected to a parametric amplifier 10 whose output appears at a port 12. A fraction of the output is frequency doubled at 13, and is used to phase lock a transit time oscillator 15 which pumps the amplifier 10. The input to the frequency doubler may alternatively be taken from a point preceding amplifier 10. The frequency doubler 13 and parametric amplifier 10 may be varactor diodes, while the oscillator may be a Gunn or IMPATT device. PSK detector.-By inserting a time or phase delay element in the pump circuit, the amplifying device may be used to detect microwave phase shift keyed (PSK) signals, Fig. 2. In Fig. 2 an input signal passes from an amplifier 19 to a hybrid T junction 25 either via the parametric amplifier 21 or via an amplifier 22. Two detectors 36, 37 are connected to the junction 25, and their outputs are differentially compared at 40. The delay introduced by the element 32 is equal to the time between consecutive bits in the data bearing signal, and hence consecutive bits are compared by detectors 36 and 37. In the event of a phase change, an output appears at the differential amplifier terminal 41. The amplifiers 19 and 22 may be tunnel diodes or parametric devices, in which latter case the oscillator 30 may pump all the amplifiers. By suitable choice of dimensions, the PSK detector may be used for 2 or 4 level PSK signals, Figs. 3, 4 (not shown). Either synchronous or coherent pumping may be used, the latter involving a reduced bandwidth suited only to digital data. The delay element may be placed in one arm of the junction 25 instead of in the pump circuit. An alternative circuit produces an output directly representing the marks and spaces of the signal to be detected, and uses a frequency quadrupler, the output of the oscillator being halved before it is applied to the parametric amplifier.

Abstract: Nickel is electrolessly plated on cleaned pretreated catalytically coated non-conductive material, such as glass, ceramic or acrylonitrile-butadiene-styren copolymer plastic, by treating the material with a solution containing nickel, ammonium and hypophosphite ions, and free from chloride or sulphate ions, having pH of at least 8 at 70-140 DEG F.  The ions may be provided by directly dissolving nickel ammonium hypophosphite complex, or by supplementing nickel ammonium glycolate solution with ammonium hypophosphite, and maintaining the pH with excess NH4OH. The solution may be regenerated by reacting NiCo3 or Ni(OH)2 with ammonium hypophosphite or glycolate.  The catalytic coating is prefarably an adherent deposit of Pd formed on an initially cleaned, delustered or etched (e.g. with CrO3) surface.  The Ni plated material may be subsequently electro-plated.

Patent GB-1549546-A (GB)
Title: Meshing-screw type rotary hydraulic machine
IPC: F03C2/08
Filed: 1977-10-04
Abstract: The machine can work as a pump or a motor. In the first case, the fluid flows from the low-pressure side to the high-pressure side. In the second case it is the other way round. The pressure difference between high pressure and low pressure attempts to push the conveyor worm (1) towards the low-pressure side (65). In order to compensate for this axial thrust, the conveyor worm (1) is provided with a compensation piston (2). In addition there are frictional forces which act in an axial direction. In a motor these forces act in the same direction as the pressure force due to the pressure difference; in a pump they act in the opposite direction. In the case of the pump, the piston area should be chosen to be smaller, and in the case of the motor to be greater than would be required for pressure equalisation. So as not to have to provide the conveyor worm (1) with different pistons (for pump or motor mode), the free end of the piston is given a smaller area (6, d2) than would be required for pressure equalisation, said smaller area being acted upon by the pressure (65) which prevails at the other end of the conveyor worm (1). The piston (2) further has a second area (d1) which is acted upon by an intermediate pressure between the high pressure (67) and the low pressure (65). The sum of the smaller area (6, d2) and the second area (d1) is greater than the area which would be required for pressure equalisation. The intermediate pressure arises in a chamber (9) which is bounded by piston (2) and its bearing (3) and which communicates with the high pressure and low pressure side (67, 65) via leak points (64, 66). The throttle effect of these leak points changes as the piston (2) moves. <IMAGE>
