Title: Closure device for flexible walled container
IPC: B65D33/16
Filed: 1975-04-28
Abstract: 1506457 Bag closures C FRANKLIN 28 April 1975 17449/75 Heading B8K A closure device for a flexible bag comprises a pin 22 around which flattened walls of the bag adjacent an opening therein can be wrapped, and a generally cylindrical resilient sleeve 24 having a slit 26 over at least a portion of its length and dimensioned to be slid along the length of the pin with the wrapped-around walls of the bag trapped between the pin and the sleeve and the flattened walls extending through the slit, as in Fig. 3. The pin includes an enlargement at one end to facilitate withdrawing the pin from the sleeve. As described a colostomy bag 10 having single or double walls of PVC welded at 12 has an opening 14 surrounded by a welded-on flange 16, and a lower neck 20 with an open end. The neck may be sealed by the pin and sleeve closure device. The pin may be of polypropylene and the sleeve of polypropylene or polythene. The slit 26 may extend over part or all of the length of the sleeve and may diverge at at least one end. The pin may be longer than the sleeve and have a screw-thread or one or more annular barb-like projections at its end which projects from the sleeve in use to enable an end closure device to be fitted thereto to prevent the pin leaving the sleeve inadvertently.

Title: Improvements in or relating to binders or adhesives
IPC: C08L93/00
Filed: 1923-02-06
Abstract: A flexible adhesive or binder comprises a varnish prepared from linseed oil or china wood oil and a gum, for example, dammar, kauri, or copal, and to which is added a dried, for example, borate of manganese, operating outwardly towards the exposed surface of the adhesive.  To accelerate the drying from the exposed surface inwardly, and to improve the adhesive properties, electrolytic process white lead, known as "Dowdy white" is added; a paste drier, for example, lead acetate and resinate of manganese, also may be employed.  When a more fluid adhesive is required, a japan drier is used, for example, "schrack japan."  In preparing the varnish, the oil is boiled until it reaches nearly a solid state, and the varnish may comprise three parts of gum dammar with two parts of linseed oil. Castor oil may be added when the drying action is to be retarded.

Abstract: 735,398. Electric selective signalling systems. NORTHROP AIRCRAFT, Inc. June 24, 1953, No. 17487/53. Class 40 (1). [Also in Group XL(b)] Information voltages appearing in a plurality of channels INFO1-INFON (of which only three are shown) are applied successively to a common channel 30 through gate stages including diodes V2, V3, V4, &c. which are normally conducting to short-circuit the channels and are rendered non-conducting by voltage pulses derived from a circular assembly of glow discharge tubes NE 1 -NEN ionized in succession by a radio-frequency field produced by a rotating electrode 6 connected to an oscillator 10. Three of the tubes, NE 1 -NE 3 , are connected in parallel to a further diode V1 controlling a fixed potential channel 21 and serve to produce a synchronizing pulse three times as long as the information pulses once per revolution of electrode 6. The tubes have their anodes connected to a voltage Sa lower than the extinguishing voltage and, with the exception of tubes NE 1 -NE 3 , are so spaced that each one extinguishes before the next one following is ionized. The cathodes of diodes VI, V2, V3, &c. are connected to a negative source 26, and points A, B, C, &c. do not rise above earth potential with maximum input of information voltage. When the diodes are cut off, however, points A, B and C, &c. are enabled to travel positive in dependance on the information voltages and corresponding voltage pulses appear on the output channel 30 through the germanium diodes GD1, GD2, GD3, &c. Diode 22 limits the voltage excursions on channel 30 to the positive direction. The voltage pulses on channel 30 are applied to the grid of triode 36 and appear amplified at the anode. The grid is normally held at a negative potential by the voltage developed across resistor R7 by diode V6 but is allowed to go positive in dependance on the information pulses by rendering the diode non-conducting. This is effected by means of pulses coincident with the gating pulses derived from across load 46 common to all the discharge tubes and applied through amplifier, invertor and D.C. restorer 42 to the cathode of diode V6. The grid of triode 36 rises from the preset negative potential to earth potential when a channel with zero information is gated and to a positive potential proportional to the information voltage when a channel with information is gated.

Abstract: 667,976. Artificial respiration apparatus. TALLEY, H. A. E. June 6, 1950 [July 7, 1949], No. 17986/49. Class 81 (ii). In resuscitation apparatus means for automatically filling the lungs with oxygen and emptying them is combined with means for supplying the oxygen to the patient for normal respiration. Oxygen from either cylinder 1 passes through a pressure regulator 5 to a changeover cock 6 which, for resuscitation, directs it to a jet 7 in a venturi tube 8, the forward side of which is connected to a valve 10. A pipe 19 connects the suction side of the venturi to a chamber 18, having one face 17 formed as a pressure-sensitive diaphragm, this being connected through a snap over toggle mechanism 15 to the stem 9 of the valve 10. The patient's face mask 14 is connected through a tube 12 to the upper side of valve 10 and also to the chamber 18. When the valve is in the position shown, oxygen issuing from jet 7 passes to atmosphere through outlet 11 and in so doing creates an increasing vacuum in the chamber 18 and the face mask 14 until the diaphragm 17 is drawn in sufficiently to trip the toggle lever 15 and reverse the valve 10. The outlet 11 is thereby closed and gas from the jet 7 can pass to the lower tube 12 and build up a pressure in the mask 14 and chamber 18 until the diaphragm again reverses the valve, the cycle continuing repeatedly. When the patient breathes normally the cock 6 is set to direct the oxygen to the pipe 20, while cutting off the jet 7. The gas now flows through a valve 25 controlled by a diaphragm 23, so as to be opened at each inspiration of the patient. A non-return exhaling valve 26 is used under these conditions.

Abstract: 715,427. Indicating-apparatus.SIEMENS & HALSKE AKT.-GES. July 16, 1952, No. 18042/52. Class 106 (4). (Also in Groups XXXII, XXXVI and XXXVII] A filar suspension mounting employed for the rotatable part of measuring, recording or indicating instruments or switch gear, more particularly for relay armatures is characterized in that the stirrup, ring or the like in which the ends of the suspension are secured is initially tensioned by a spring which is effective in a direction extending coaxially with or parallel to the suspension. As shown, Fig. 1, a rotatab!e part 4, e.g. the pointer of a measuring instrument or the armature of an electromagnetic relay is carried on a filar suspension 3 by a stirrup 1 which can be secured by screws through holes 2 to the frame or housing of the instrument or relay. The suspension 3 comprises a flat steel band of rectangular crosssection which has a bore at top and bottom for the purpose of riveting projections 1' and 1" at the top and bottom on the front of the stirrup 1. A pre-tensioning spring 5 extends parallel to the suspension 3 and is formed from a metal plate cut in the shape of a parallelogram by bending into cylindrical shape with a slot between two parallel edges disposed parallel with the axis of the cylinder and the top and bottom corners displaced. Two sleeves 6<SP>1</SP> and 6<SP>11</SP> with the spring 5 between fit loosely on a threaded pin 7 screwed into the top of the stirrup, projecting loosely into an opening in the lower part and having a part of reduced diameter, above the sleeve 6' to form a pressure surface against which the sleeve 6' bears. The spring may be suitably tensioned by tightening the pin 7 and the initial tensioning force can be very considerable without danger of being appreciably lowered due to fatigue in the material of the stirrup.
