Title: Improvements in or relating to time delay devices
IPC: G04F1/00
Filed: 1961-07-19
Abstract: 932,158. Dashpots. BROOKHIRST IGRANIC Ltd. July 19, 1961 [Aug. 30, 1960], No. 26145/61. Class 108(3). In a pneumatic time delay device in which a flexible diaphragm 14 divides a cavity in a body 10 with a cover plate 12 into upper and lower chambers the diaphragm is arranged to seal and open respectively a part annular exhaust passage 44 leading from the lower chamber to atmosphere when the pressure developed in the lower chamber is correspondingly below and above the exhaust pressure. The annular passage 44, which is formed concentrically about a part-spherical cavity 38 in the body 10, communicates through short passages 46 with a passage 48 which extends across the body 10 and has filters 50 in its outlet openings. The diaphragm 14, has a bead 14a which seats in an annular recess 52 in the body 10 and is clamped between the latter and a flange 12a of the cover plate 12 which is secured to the body 10 by screws 56 and has a ring of apertures 60 open to the atmosphere, the lower chamber, formed by the cavity 38, communicates through a small passage 40 with the tapered inner end portion 42a of a passage 42 which leads to the transverse passage 48 and is internally threaded to receive the threaded portion of a metering pin 64 having a tapered portion 64a which co-operates with the taper 42a. The centre portion 14d of the diaphragm 14 is moulded to the head 16a of a pin 16 which extends through a nylon bearing 62 in a centre boss 12c on the cover plate 12 and has a stop 18 connected to its outer end a compression spring 22 being constrained between the cover plate 12 and a cup member 20 which co-operates with the stop 18 and the arms 26a of a toggle switch lever 26. Upward movement of the rod 16 from the position shown in Fig. 2 is retarded air only entering the lower chamber at a restricted rate through the opening 40 the exhaust passage 44 being closed by the peripheral portion 14b of the diaphragm 14. The build up of pressure in the lower diaphragm chamber as the rod 16 descends causes the edge portion 14b of the diaphragm 14 to be lifted off the passage 44 and provide rapid exhaustion of air from the lower chamber. A small space X between the diaphragm edge portion 14b and the adjacent portion 12a of the cover plate 12 is provided to accommodate the raising of the diaphragm portion 14b.

Title: Electrical noise-making devices
Inventor: FEAVER JOHN LIONEL
IPC: H03K3/30
Filed: 1962-07-10
Abstract: 1,000,536. Audible warning devices; audible signalling. RONALD TRIST CONTROLS Ltd. July 10, 1963 [July 10, 1962], No. 26477/62. Headings G4F and G5J. [Also in Division H2] An audible warning device includes a diaphragm 6, magnetically coupled to the core of a saturable reactor 3 forming part of an oscillatory circuit including transistors 1, 2 together with coils 4, 5 wound on the central polepiece 7. The coupling between the coils causes the current in the more heavily conducting transistor to increase and the current in the other to decrease until saturation of the core takes place which causes the direction of flux to reverse resulting in the rapid turning off of one transistor and turning on of the other. D.C. or A.C. supply may be used and with A.C. the audible output is not goverened by the supply frequency. The air gap between the diaphragm 6 and the polepiece 7 and annular core member 8 is small so that the diaphragm, or a device mechanically coupled to the diaphragm, is influenced directly by the alternating magnetic flux resulting from the square-wave current flowing in the two windings 5. The audio warning frequency may be changed by altering or adjusting the values of the circuit components. The sound produced by the diaphragm may be acoustically amplified by diaphragm resonance or resonated by means of a horn or resonant tube. The output can be increased by using a driven inverter stage, silicon rectifiers as the switching elements, and mechanically coupling part of the magnetic circuit to the diaphragm.

Filed: 1953-09-29
Abstract: 764,589. Respiratory appliances. CONITECH, Ltd. Sept. 29, 1953, No. 26700/53. Class 81(2) A pump, connected with an inflatable chest piece through a fluid passage, has control means, independent of the passage, for determining the limits of vacuum and pressure which are applied to the patient. The pump is preferably of the bellows type, comprising a top plate 22, a piston 24 and a connecting bellows 36. The piston slides on a hollow tube 58, and is oscillated by a connecting rod 68 connected to a crank 74 which is driven through a reduction gearing 80 by an electric motor. An aperture in the upper plate 22 has provision for connection with a hose leading to the chest piece. In order to limit the degree of vacuum, air may be admitted to the interior of the pump through holes 190, the interior of the tube 58, a controllable port 171 and a duct 186. The effective size of the port 171 is varied by turning a control knob 174 and thereby rotating a suitably shaped body member 184. The expulsion of air from the interior of the bellows, to limit the positive pressure, is controlled by a light disc valve, arranged to close during each suction stroke but which, during the pressure strokes, opens to an extent determined by an adjustable stop mounted above it (see Fig. 4, not shown). If desired, stand-by manual means may be provided for actuating the pump.

A water-soluble inorganic salt, e.g. sodium chloride and a waterimmiscible organic solvent, e.g. hexane, are added to the distillate to form a two-phase system and after separating the phases, the 2-methyl-3-buten-2-ol is recovered from the organic phase by distillation while maintaining the pH at at least 4. The addition product is prepared by initially introducing a portion of the isoprene to be reacted into a reaction vessel, adding the hydrohalide to the initially added isoprene until the isoprene is saturated and the hydrohalide is in excess, adding the remaining isoprene and hydrohalide, the rate of addition being such that there is an excess of hydrohalide present until all isoprene has been added to provide equimolar amounts of isoprene and hydrohalide.

Title: Improved processes for the production of aluminium fluoride-alkali fluoride double compounds
IPC: C01F7/54
Filed: 1930-09-08
Abstract: Residues occurring in manufacturing, casting or melting aluminium, and known as aluminium ash, scrap, and ball mill dust are dissolved in hydrochloric or sulphuric acid or mixture thereof, and the filtered solution is treated with alkali fluoride, or with hydrofluoric acid and alkali chloride, sulphate or admixture thereof, or with a mixture of alkali chloride or sulphate with alkali fluoride and hydrofluoric acid, thereby precipitating alkalialuminium fluoride.  Prior to the treatment of the solution of aluminium chloride or sulphate in the above manner, ground fluorspar with or without sulphuric acid, or hydrofluosilicic acid or its sodium salt may be added.  The solution of aluminium fluoride thus obtained is filtered from insoluble substances such as calcium sulphate or silicic acid, and treated as above to obtain the double fluoride. Hydrochloric or sulphuric acid liberated in the process may be employed for dissolving fresh raw material.

Abstract: 1,274,365. Photographic copying. HORIZONS RESEARCH Inc. June 3, 1970 [June 11, 1969], No.26884/70. Headings G2A and G2C. A process for obtaining a copy of an original on a sheet containing a free-radical non-silver photo-sensitive composition comprises sensitizing the material by a preliminary blanket exposure to ultraviolet or near ultraviolet radiation, making the exposure with red light by reflex contactprinting, and then fixing the image. As shown, the original 14 and copy sheet 16 are passed in contact round a drive roller 12, against which they are held by an endless transparent belt 22. The preliminary exposure is provided by a lamp 40 as the sheets pass into the housing containing the apparatus, but normal room illumination will have the same effect. The main source of illumination is the lamp 30, the light from which passes through a red filter 34 and a heat-absorbing filter 36. The contrast can be controlled by means of the lamp 40. If the intensity of this lamp is kept low, a high-contrast copy is obtained, and vice versa. If the heat-absorbing filter is removed, a positive image is produced, instead of a negative image. The image is fixed by heating the copy sheet, which serves to drive a volatile activator out of the sensitive material.
