Title: Control valves
IPC: G05D7/01
Filed: 1973-08-10
Abstract: 1435930 Valves EMHART (UK) Ltd 30 July 1974 [10 Aug 1973] 37910/73 Heading F2V In a valve for use in glassware forming machines, variable restricted flow is provided for flow between a port 3 and a port 4 connected to a cylinder and unrestricted flow is permitted in the reverse direction. A double frusto-conical seat 11, 12 is provided in a sleeve 8 and a frustoconical valve member 13 co-operates with the seat 12. The valve member is a sliding fit on a stem 17 and is loaded by a spring 19 towards the seat 12 and a stop 18 on the stem. The position of this stop, and hence the aperture between the closure member and the seat, is varied by moving the stop longitudinally, the stem 17 being an extension of a screw-threaded stem 14, 15. A nylon pin 9 secures the sleeve 8 to a screw-threaded plug 6 and provides frictional resistance to turning of the stem. For flow in the reverse direction the valve acts as a spring- loaded check valve. In another embodiment, Fig. 2 (not shown) flow from port 3 to port 4 is unrestricted but flow in the reverse direction is restricted. In this case the valve member co-operates with the seat 11 and slides upwardly on its guiding stem in the check valve mode of operation, a stop (22) being provided on the lower end of the stem. In an alternative embodiment providing restricted flow in each direction, Fig. 3 (not shown), there are two valve members, each spring- loaded and sliding on an adjustable stem, co-operating respectively with the two valve seats 11, 12. The screw-threaded stem (14a) (on the lower valve member) extends downwardly through the valve body.

IPC: G06V30/224
Filed: 1958-11-26
Abstract: 867,616. Automatic character reading. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Sept. 9, 1959 [Nov. 26, 1958], No. 38090/58. Class 106 (1). In a character reading apparatus the character is projected on to one or more photo-cells by an optical system which is adapted to produce a greater magnification in one direction than in the direction at right angles. The characters are formed with code bars 2, 3, 4, Fig. 1, which, ideally, would alone be sensed by a small area. A moving vertically over the character, and producing the waveform of Fig. 2. But lack of accurate sideways positioning of the character would greatly distort these signals. To compensate for such malpositioning, the scanning area is increased relatively (area B) by a reduction in the size of the character in the optical system. The area is now as wide as the character and deeper than the thickness of the code bars. The code signals are accordingly less well defined (Fig. 3). To sharpen up these signals and reduce the background noise level the character is magnified in the vertical direction so that in the stretched image, the code bars have a width similar to the width of the area B. Relatively, therefore, the scanning area is as represented at C and the sensed signals are shown in Fig. 4. The optical system consists of a cylindrical lens 8, Fig. 5, which stretches the character vertically and a cylindrical lens 9 which focuses the image on the photo-cell 11. Instead of a single lens 9 there may be a series of parallel lenses each projecting part of the image on to a corresponding photo-cell. The code bars may not be part of a character. Alternatively, code marks may consist of horizontal gaps through a character. Specifications 793,103 and 806,125 are referred to.

Abstract: 922,656. Discharge apparatus. GENERAL ELECTRIC CO. Ltd. Nov. 8, 1961 [Nov. 8, 1960], No. 38332/60. Class 39 (1). [Also in Group XI] For introducing a predetermined quantity of vapour into an enclosure, e.g. the bulb of a tungsten filament lamp or an electric discharge tube, the enclosure is connected to a pumping system by a stem having a side tube containing the source material for the vapour, the side tube being maintained at a sufficiently low temperature to prevent substantial loss of vapour from the source material, introducing a filling gas, sealing off the enclosure and side tube and heating them to vaporize the source material and allow the vapour to diffuse into the enclosure, the temperature being such, in relation to the dimensions of the enclosure, stem and side tube and to the pressure of any filling gas present, that the required quantity of vapour is introduced into the enclosure before the equilibrium vapour pressure is attained and the heating being continued for a time sufficient for diffusion to take place but insufficient for establishment of equilibrium vapour pressure and finally sealing off the enclosure, or individual bulbs or tubes forming part of the enclosure, from the stem. A bulb 1 or a series of bulbs or tubes sealed to a manifold is connected by a pumping stem 2 to a pumping system (not shown), the stem 2 having a side tube 3 containing iodine crystals 5, the tube 3 being immersed in water and melting ice. An iodine trap 4 containing pellets 6 of molecular sieve zeolite is interposed between the stem 2 and the pump, the trap being surrounded by liquid nitrogen until the greater part of the air has been removed from the system. After pumping, the bulb 1 is baked to remove residual gas and an argon filling is introduced. The system is then sealed off at A and immersed for the necessary time in boiling water, after which it is cooled and the bulb sealed off at B.

Abstract: 1365687 Solid state cells GOULD Inc 23 Aug 1971 [31 Aug 1970] 39470/71 Heading H1B To prevent build-up of a highly resistive layer on the anode of a solid state cell formed by the reaction of a mobile oxidant from the cathode with a constituent of the anode, the anode includes an additive material which reacts with the resistive layer material to form a low resistance product. As described, the mobile oxidant is iodine, the anode constituent is silver and the resistive layer material is AgI. The preferred additive material is Rb 2 AgI 3  which reacts with AgI to form the low resistance electrolyte material RbAg 4 I 5 . Preferably, both the anode and cathode are in the form of layers and comprise a mixture including carbon and electrolyte similar to the electrolyte used in the solid electrolyte layer of the cell, the low resistance product produced in the anode being similar to the electrolyte already present. In addition to the carbon and electrolyte the anode contains silver and the cathode contains iodine as part of an organic or inorganic complex, the preferred iodine source being an ammonium polyiodide, e.g. tetramethylammonium pentaiodide, N(CH 3 ) 4 I 5 . Alternative electrolytes are represented by the formula MAg 4 I 5  where M represents K, Rb, NH 4  or C 5  or by the formula QAg n I n+1  where n varies between 3 and 39 and Q is an organic ammonium cation. Other electrolytes include Ag 3 SI, Ag 7 I 4 PO 4 , Ag 19 I 15 P 2 O 7 , and Ag 5 I 3 SO 4 . Alternative anode additive materials are RbI, Rb 2 AgI 3 , MeNI, (CH 3 ) 4 NAg 2 I 3 , Ag 3 PO 4 , Ag 2 S. The cell may include the feature disclosed in Specification 1,366,535, in which the electrolyte contains silver for reacting with the iodine to form AgI dispersed in the electrolyte, and the present invention discloses the addition to this electrolyte of the additive material added to the anode whereby the highly resistive AgI is reacted upon to form a low resistance product. In one embodiment a eutectic composition of Rb 2 AgI 3  and RbAg 4 I 5  is used in the anode cathode and electrolyte layers to serve both as the electrolyte and as the additive. In several examples described the anode has two layers, the layers adjacent the electrolyte layer either having no electrolyte or a greater propertion of additive compared with the other layer. The cell is encapsulated in resin.

Abstract: <PICT:0343253/IV/1> <PICT:0343253/IV/2> Cakes of artificial silk after purification and drying are packed and transported in flattened form and subsequently reeled or wound on to bobbins.  The cakes may be flattened by drawing out the original circular cakes in radial direction, or by pressing opposite sides together.  Two parallel pins may be inserted inside the cake and then separated to such a distance that the cake is sufficiently flattened.  The cakes may be bound with lashing threads before or after flattening and they may be treated with a sleeking composition which causes the threads to adhere to each other.  A suitable sleeking composition consists of beeswax, Japan wax, stearic acid, and oleic acid or red oil melted together and mixed with dilute caustic soda.  Soap solutions may also be used for this purpose.  The flattened cakes are laid between stiffening plates a and b which are secured together for instance by cords so that neither the cakes nor the individual threads can shift. Instead of two separate stiffening plates, a single U-shaped plate may be used.  The stiffening plates may be of thick paper, cardboard, papier mach<\>ae, artificial material or light metal. Two or more flattened cakes may be placed side by side and secured between the same stiffening plates.  The small parcels thus formed may then be packed together into larger bundles or placed in cardboard boxes.  The cakes may be packed in columns as shown in Fig. 9, a sheet of paper or cardboard q being placed between each layer of cakes s.  At the foot and top of the pile a thicker sheet of cardboard or a thin wooden sheet h may be placed.  The pile is pressed down and tied up in the box which may be lined with tissue paper or oiled paper o.  After transport the cakes are unpacked and opened out into ring form. Stiffening rings of rubber or celluloid may be inserted and the thread drawn off endwise for transference to reels, cops, or bobbins. The thread may also be drawn off tangentially by inserting reel-like supporting devices and rotating the cakes.
