Abstract: 1,082,582. Multi-dose hypodermic injector. R. P. SCHERER CORPORATION. May 25, 1965 [Aug. 17, 1964], No. 22232/65. Heading A5R. A multi-dose hypodermic injector, having a cylinder with a piston operable in one direction to draw medicament into the cylinder from a medicament container, and in the other to expel it from a discharge orifice, has a three-way valve between the cylinder and the orifice, permitting communication of the cylinder with either the container or the orifice, and means permitting entry of air to the container when the latter communicates with the cylinder, but sealing the container from the air when the orifice communicates with the cylinder. Such means is preferably incorporated in the three-way valve, by a duct therein which is brought into connection with the atmosphere. In Fig. 1, the valve plug 20, which is rotatable, has a T-shaped duct, with arms 23, 24 and 25, which can connect with ports 26, 28, and 30 which themselves communicate with respectively the cylinder 27, the orifice 18, and, via a medicament tube 50, the container 32. The plug also incorporates an L-shaped duct, with arms 62 and 63, which, according to the position of the plug, serves either to seal off the container from the atmosphere, as shown in Fig. 1, or when the valve rotates to connect the container with the cylinder, as shown in Fig. 4, to allow entry of air to the container from a port in the face 66 of the cylinder, through a gap between this face and the nose piece 12. Air is admitted to the container by an air duct 52, which is in conjunction with the medicament tube 50, the double tube being sharpened to pierce the closure of the container. In Fig. 1, the parts 40 and 41 comprise a telescopic arm whereby a holding member 44, with a pad 46, serves to hold the container in place. The valve plug is rotated between its two positions by a handle, 27, moving between two stops 29 and 31.

Abstract: 477,628. Preventing yellow stain in photographs. STEIGMANN, A., and SAGER & DR. GOSSLER GES., F. Aug. 14, 1936, No. 22490. [Class 98 (ii)] Yellow stain in photographs is prevented by addition of iodonium compounds in small quantities, of the order of 0À1 to 0À2 grams per litre in the case of a silver halide emulsion or a developer, to the layer of photographic positive or negative material, such as a silver halide emulsion, or to another layer closely associated therewith, such as a protective, carrier, baryta, or backing layer, or to washing waters, developers, or fixing baths. Diphenyl iodonium nitrate may be added to a silver chloride emulsion prior to ripening, and diphenyl iodonium acetate may be added to a metol-hydroquinone developer. In emulsions, the addition influences the formation of grain, and in fixing baths, the addition effects regeneration. References are made to the use of iodosobenzene and of thallium salts.

Title: Improvements in the production of raw rubber from rubber latex
IPC: C08C1/15
Filed: 1927-08-27
Abstract: 300,719. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges,). Aug. 27, 1927. Latex, coagulating.-Rubber is coagulated from latex by proteases in the presence of additional substances facilitating the reaction or improving the properties of the rubber, such as hydrocyanic acid, hydrogen sulphide or saline mixtures possessing buffer properties. Suitable proteases are those contained in succus caricae papayae. The properties of the rubber can be improved in a controllable manner by imparting to the latex such a hydrogen-ion concentration that the coagulation is accelerated or retarded thereby. In an example, air is passed through latex stabilized with ammonia until a hydrogen-ion concentration of pH = 8 is attained : 100 c.c. of a 2 per cent solution of succus caricae papayae are added to 5 litres of the latex: after 20 hours a dense coagulated product separates out. If hydrocyanic acid is added the time of coagulation is reduced to 7 hours. With a higher ion concentration the time of coagulation is shorter.

[Class 75 (iii)] The catalyst P is mounted in a holder 153 between an upper perforated disc or wire screen S of nickel-chromium alloy, such as that known under the Registered Trade Mark " Nichrome," and a lower perforated disc or wire screen S<1>, preferably made of "Monel" (Registered Trade Mark) metal. The screens S, S<1> may be approximately of 70 and 100 mesh respectively. A cup-shaped retainer ring R is preferably also made of "Monel" metal. The holder 153 fits in a heat-resisting gasket 148 in a cup 135 and is spaced from the latter by tongues 145, and a recess 146 prevents the tip of a cigarette from touching the holder. The tongues 145 may engage an internal bead in the cup 135. As shown in Fig. 3, the cup 135 has a shoulder 136 resting on a sleeve 131 slidable in a casing 125 having a sleeve 126 screw-threaded at 130 to receive a cover (not shown). On removing the cover, the sleeve 131 is raised by a spring 144 to disengage a tube 139 from a gasket 129 and, upon drawing upon a cigarette applied to the screen S, air is drawn through inlets 134 over the surface of absorbent-material 143, saturated with fuel, and passes with fuel vapour up the tube 139 to the catalyst P. As shown in Fig. 9, the catalyst cup 135<1>, provided with ventilation holes 103, is fitted with a baseplate 65 detachably connected to an arm 30 pivoted to a spring-controlled hinged lid 28, as described in Specification 452,376, so that the cup is brought over an outlet 42 when the lid is opened. The arm 30 carries a rubber &c. pad 41 and is provided with a stud 51 for engagement by the lid in the closed position to press the pad down to seal the outlet 42 and the inlet 43 to an air tube 44. The latter extends through the absorbent-material 46, which is held spaced from the casing 36 by perforated plates or screens 45, 47. The casing 36 is of streamline section.

Title: Improvements in or relating to data stores
Inventor: WILLIAMS MICHAEL
Filed: 1960-06-28
Abstract: 928,847. Magnetic storage devices. GENERAL ELECTRIC CO. Ltd. Aug. 11, 1961 [June 28, 1960], No. 22612/60. Class 40 (9). A data store matrix panel comprises a magnetic thin film with two sets of drive conductors, each conductor of at least one set having a forward and a return portion, which portions are parallel and in conjunction with a particular conductor of the other set modifying the sense of magnetization in different areas of the film. Digit conductors having forward and return portions 5, 6 are formed by cementing a thin aluminium foil to a film of polyethylene terephthalate and photo-etching the foil, after which the aluminium is anodised and the conductor structure is cemented on to a thin magnetic film on aluminium substrate 1. Word conductors, also having forward and return portions 11, 12 are printed on a copper-clad surface of a phenolic plastic board which is then laid against the digit conductor sheet. When a digit is written into the store by energization of conductors 5, 6 and 11, 12, the magnetization in four areas 18, 19, 20, 21 of the film is modified. It is arranged that a current pulse along a word conductor should cease before that along a digit conductor starts to fall. For read-out a current pulse is applied to conductor 11, 12 which rotates the magnetization in the four areas to produce additive currents in conductor 5, 6. If the read-out pulse is made smaller than a writing pulse, read-out may be non-destructive. Alternatively, provision may be made for rewriting the information read out. The speed of operation of the store may be increased by replacing conductor end portions 9, 15 by resistors matched to the impedance of the conductors 5, 6, 11, 12. In a further embodiment (Fig. 5), a U-shaped copper support 24 carries two halves of a matrix, each half comprising an aluminium substrate on which is deposited a film 800 Angstroms thick of 80/17/3 Ni/Fe/Co. Copper word conductors, each having a forward and a return position, are photoetched on a polyethylene terephthalate film which is cemented on to the magnetic film, and digit conductors, each consisting of a single portion, are similarly formed on an insulating film and cemented to the first film. A transformer 34 is provided for each digit conductor and has the ends of its secondary winding connected to one digit conductor in each half of the matrix, and a centre tap connected through coaxial line 35 to a sense amplifier. In this embodiment the same information is stored in two adjacent magnetic areas. An arrangement is also referred to in which the conductors have more than two series connected portions. If desired separate sense conductors may be provided, together with inhibit conductors if required. Specification 905,340 is referred to.
