Title: A method and apparatus for purifying liquids
IPC: C02F1/52
Filed: 1961-03-30
Abstract: <PICT:0987978/C1/1> Waste waters, containing solid particles, are treated with conventional flocculating, collecting and frothing agents and oxidizing gases in a two-stage process.  The first stage is a beating action to produce complete oxidation followed by intense stirring with a gasiform medium which produces a highly subdivided dispersion of minute gas bubbles and minute solid particles which coalesce into a miscella and the sludge thus formed is removed from the surface.  The sludge may be recirculated.  Liquid under treatment is fed into stage I by nozzle 30 and overflows via channel section 32 into stage II of the apparatus, which is described in Specification 730,635; leaving for final separation in vessel 11.  In stage I the bearing member 24 is used without liquid-tight packing of the spindle, air being sucked through inlet 47.  Frothing agent is advantageously added by inlet 48 while the other conventional treatment materials are added prior to introduction of the water b pipe 30. <PICT:0987978/C1/2>

Title: Improvements in or relating to valves
IPC: F16K11/044
Filed: 1968-03-13
Abstract: 1,208,973. Valves. SOC. GENERALE DE FONDERIE. 13 March, 1968 [17 March, 1967], No. 12177/68. Heading F2V. A manually operated valve designed to control the flow of water from an inlet 3 to either an outlet 1, which has connected thereto a bath tap, or to an outlet 4, which has connected thereto a shower head, includes a valve member 23 which is formed from two resilient washers 24 and 25 retained in an H-shaped holder 26 and which is movable between two aligned and opposed seats 9 and 22. In operation, springs 33 and 42 retain the valve member in the position shown whereby the shower outlet 4 is isolated and flow from the inlet 3 to the tap outlet 1 takes place via ports 17, which ports are formed in a fixed sleeve 16 within which the valve member is slidable in a non-fluid tight manner, and seat aperture 8. Upon depressing a button 35, 38, a part 39 thereof strikes the valve closure member stem 27 and consequently moves the. closure member into engagement with seat 9 (Fig. 2, not shown). Subsequent release of the button results in only the latter being returned by spring 42 to its uppermost position, the closure member remaining in contact with seat 9 as long as the fluid pressure acting thereon exceeds the returning force exerted by spring 33 [Fig. 3, not shown). In this second position of the valve member, flow from inlet 3 to outlet 4 takes place via ports 17, aperture 21 and ports 43. The closure member can be moved out of engagement with seat 9 and in opposition to fluid pressure acting on the member by manually withdrawing the button until flanges 29 and 41 engage one another and thus, together with the upward bias of springs 33, 42, moves the closure member upwardly into engagement with seat 22. Figs. 5-7, not shown, indicate a modification whereby the trip flow rate can be reduced, whilst Figs. 8-10, not shown, indicate a further modification in which a change over from shower to tap delivery can only be achieved by reducing the pressure of water at the inlet 3.

Title: An electromechanical resonator
Inventor: ZAKARIA HISHAM MOHAMED SAADALL
IPC: H03H9/70
Filed: 1969-03-07
Abstract: 1277614 Electrostatic resonators STANDARD TELEPHONES & CABLES Ltd 5 March 1970 [7 March 1969] 12218/69 Heading H3U An electromechanical resonator comprises one or more vibrator elements 1 vibratable by electrostatic forces between itself and an electrode 2. In Fig. 1, the element 1 is fixed at one end to a support 3, and an A.C. input signal is applied from G1. Electrostatic forces cause the element 1 to vibrate, and an output appears across the load R3-C out  due to charge flowing in and out of the capacitance formed by the element 1 and electrode 2. To prevent frequency doubling the element 1 is biased by battery B1 through a high resistance R1, a capacitor C E  decoupling the bias. Because the electrostatic forces between the element 1 and electrode 2 depend on the square of the potential between them, the bias causes voltage gain. The resonant frequency of the system is determined by the dimensions and material used for the element 1 and by air damping, the latter being eliminated if necessary by perforating the element or by evacuating the surroundngs. The resonator may be operated up to a few hundred KHz, though the preferred range is 1-30 KHz, and its dimensions are submillimetric. Various combinations of such resonators are possible, e.g. a single element with separate input and output electrodes, Figs. 4-7 (not shown). Several resonators may be interconnected, either by mechanically linking the vibrator elements, Figs. 10, 11 (not shown) or by linking them electrically, Figs. 9, 12 (not shown), or by both methods. The electrodes may be electrically interconnected. Such combinations allow the passband to be tailored as required, Fig. 15 (not shown). The bias used may be applied to either the vibrator elements or the electrodes, and may be D.C. or A.C., the latter giving a modulator action. The elements, which may be strips, rods, discs or rings may be supported at any nodal point or points, not necessarily at the end. The resonator may be used as a filter, or as a transformer, and is suitable for a hybrid integrated circuit.

A variable area jet propulsion nozzle has a plurality of pivoted flaps which are moved into the nozzle restricted position by means, having a cam surface, which is movable parallel to the longitudinal axis of the nozzle. The tail pipe 30 has at its outlet end an annular ring 32 to which are pivotally attached by means of a retainer ring 39 a plurality of annularly disposed flaps 34. The ring 39 forms with the ring 30 an annular chamber 41 which receives the rolled ends 36 of the flaps. A plurality of sealing plates 42 having rolled ends which also engage the channel 41 seal the seams between the adjacent flaps 34 on the inside. Pressure plates 46 seal the seams between the adjacent flaps on the outside. The rearward ends of the plates 42 terminate in fingers 48 which hook over the ends of the pressure-plates 46. The forward ends of the pressure plates are located relative to the flaps 34 by clips 57 which may be spot-welded to the flaps. Cut-out portions 53, 55 allow relative movement between the pressure plates, flaps and sealing plates. The pressure-plates 46 are attached to the tail pipe by means of links 56 pivotally attached to brackets 60 attached to the ring 32 and by axles 52 to the side plates 50 of the pressure plates 46. The axles 52 also carry rollers 54. The rollers 54 are engaged by cam surfaces 66 attached to the inner shell 64 of an actuating ring 61 so that when the actuating ring is moved forwardly the flaps are forced to move radially inwardly. The ring 61 is pivotally attached to the tail pipe by links 72, 76. In a modification, the sealing-plates 42 and clips 57 are dispensed with. In this arrangement the flaps 34 are attached to the pressureplates 46 by means of a stud attached to the flaps which carries a cross-pin adapted to engage slots in the side plates 50 of the pressure plates. Cooling air flows between the tail pipe and actuating ring over the nozzle operating mechanism. Specification 677,188 is referred to.
