Patent GB-867184-A (GB)
Abstract: 867,184. Granulating processes. CIBA Ltd. April 28, 1958 [April 26, 1957], No. 13480/58. Class 87(2). [Also in Group VI] Pharmaceutical ingredients (see Group VI) are granulated before being tableted by treatment in a granulating apparatus with a vapour which condenses on the mass, the moistened mass being then granulated and vacuum dried. The vapour used may be, for example, a hydro-alcoholic mixture, acetone, chloroform or ether. The tablet ingredients are first blended in a rotatable vessel 1. With valves 4 and 5 closed, the liquid in a jacketed vessel 3 is boiled, the valve 4 is opened, and the vapour passes through a filter 12 of porous stainless steel, whilst the vessel 1 is rotated. When sufficient vapour has passed over, the valve 4 is closed and the valve 5 is opened. The vessel 1 is evacuated (whilst still in rotation), until all volatile liquid is removed leaving a dry, granular mass which is ready for screening and tableting. For operation under " vacuum conditions," which allows the use of lower temperatures, valves 4 and 5 are opened after the blending and the system evacuated. Valve 5 is closed, and the liquid heated allowing the vapour to pass into vessel 1 as before, the remainder of the process being unaltered.

The detent means 52 may be located on the member 16 (Fig 11) and the slot 24 in the member 16. <IMAGE>
Patent GB-2190007-A (GB)
Title: Liquid aerating apparatus with safety valve
Inventor: JEANS EDWARD L
IPC: B01F3/04
Filed: 1987-05-05
Abstract: In a liquid aerating apparatus, particularly for preparing carbonated drinks, a spring (13) is positioned between an operating lever (11) and a plunger (8) which is driven inwardly to open the gas valve (2) of a gas cylinder (3), the strength of the spring being selected so that a reduced regulated gas pressure is delivered. In operation, gas from the cylinder (3) enters a cavity (5) from which it passes via a passage (7) to the injector head. Increase of pressure in the cavity (5) above a threshold level moves the plunger (8) against the action of the spring (13), allowing the gas valve (2) to close. The plunger (8) may also co-operate with a vent passage (20) to constitute a relief valve, and to reduce the gas pressure at the end of the aeration process. Thus, should the gas valve (2) fail to close, or if excess pressure is communicated via a connection (25) from the aeration useage space, the plunger (8) is moved sufficiently for an O-ring seal (9) to expose the vent passage (20) through to the cavity (5). <IMAGE>

Each valve 41a, 41b has an input port and an output port, which communicate with each other at one position and are intercepted from each other at another position. The control unit 50 combines logically first judging results for relieving the braking of the front and rear wheels with second judging results for maintaining the braking of the front and rear wheels constant, so as to generate instructions to control the change-over-valves. <IMAGE>

Title: Heading tapes with a fleecy texture
Inventor: TILTSCHER OTTOKAR
IPC: A47H13/16
Filed: 1990-12-20
Abstract: A heading tape comprises a strip of buckram 10, the buckram being provided with regions of floating yarn 13, arranged to provide the buckram with a fleecy texture. Such a heading tape is particularly versatile. It can be used like a conventional buckram heading tape. for example to be fastened to a pelmet board by means of adhesive or tacks. It can also be attached to curtain hooks of the conventional blunt ended type, since the floating portions of yarn can be used to provide loops or pockets into which the hooks can be inserted. There is no need to pierce the buckram with sharp metal hooks in the traditional manner, although this traditional method can still be used if desired. Thirdly, because of the fleecy regions, the buckram can be releasably fastened to a support which is provided with a hooked pile of the velcro (RTM) type. <IMAGE>

Abstract: An axial thrust force-compensating apparatus in a gas turbine engine having relative rotatable first and second structures (84, 90; 92) includes a first annular part (78) mounted to the first engine structure and having an annular end surface, a second annular part (80) mounted to the second engine structure and having an annular end surface which faces toward the end surface of the first annular part and a mechanism (82) for providing separate outer and inner fluid flows (96, 98) to the respective outer and inner regions between the end surfaces at pressures responsive to the amount of separation existing between the end surfaces at those regions. The fluid flows generate primary compensating moment forces acting on the end surfaces to maintain the end surfaces in generally parallel relationship. The apparatus may also have a secondary hydraulic pressure balance mechanism (110) for producing secondary compensating moment forces which complement the primary compensating moment forces produced by the primary pressure balance means to limit the magnitude of any non-parallel relationship between the end surfaces of the first and second parts. <IMAGE>
