IPC: A45D4/16
Filed: 1951-01-30
Abstract: 693,934. Hair waving appliances. CALLINAN GILES & CO., Ltd. Feb. 21, 1952 [Jan. 30, 1951], No. 2278/51. Class 131 [Also in Group XI] A device for preheated metal clips for permanent hair waving comprises one or more reflectors behind tubular heating elements and thermostatic means for controlling the temperature of the heating elements to make them suitable for waving techniques at two different temperatures. As shown, a polished, metal,. reflector plate 13 is spaced a short distance behind tubular heating elements 12, 'mounted between casings 10, 11, and each containing an electric heater. Thermostats 15, 16 are mounted on brackets 19 in apertures 17 in the reflector, one being present to maintain the tubes at the temperature necessary for high temperature suitable for "tepid wave" technique. A third thermostat 20 is preset to a temperature slightly below the higher temperature to make provision for waving certain kinds of hair. The thermostats are urged by the brackets 19 into pressure contact with the same tube 12 or each with a different tube and each is brought into the electric circuit by the operation of its own switch. The invention also provides an adaptor for converting an existing heater and comprises a reflector, mounted by brackets 14 behind the heating tubes of the heater, and provided with two or three thermostats.

Abstract: 1,158,648. Hypodermic needles. L. D. KURTZ. 17 Jan., 1967 [6 Oct., 1966], No. 2403/67. Heading A5R. A hypodermic needle comprises a body portion, a cutting edge located at the distal end of the needle adjacent the tip thereof and formed by the intersection of two plane surfaces to extend through the longitudinal axis of the needle from one side of the needle to the other side thereof, and a channel extending longitudinally in the body portion for conveying liquid therealong, the channel opening on to the periphery of the needle only at a point or points proximal of the cutting edge. As illustrated in Figs. 1 and 2, cutting edge 12 of needle 10 is formed by the intersection of plane surfaces 13 and 14 to extend between pointed tip 11 and diametrically opposed second point 15. Located on the surface of the body portion 16 of the needle is longitudinal groove 17 constituting a channel terminating at 18 in annular groove 24 which is located proximally of the proximal edges 19 and 20 of the plane surfaces and therefor proximally of the most proximal part of the cutting edge. Surrounding the body portion of the needle is catheter sheath 21 which co-acts with the longitudinal groove to form an enclosed passage. The distal end 31 of the catheter sheath and the adjacent surface 30 of the needle preferably are shaped as illustrated, the maximum diameter of the needle in the region of the cutting edge being preferably equal to the external diameter of the catheter sheath but greater than the diameter of the portion of the needle which is enclosed by the catheter sheath. Fig. 6 (not shown) illustrates a hypodermic needle in which the catheter sheath is omitted, the channel being formed by a longitudinal bore extending through the body of the needle to terminate in a radial bore opening on to the periphery of the needle; if desired, the radial bore may open into an annular groove.

Filed: 1952-02-06
Abstract: 715,350. Hypodermic needles. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 25, 1953 [Feb. 6, 1952], No. 3176/52. Class 81(2) A container for a hypodermic needle is so shaped that the needle cannot be rotated therein and is provided with resilient means to prevent its accidental withdrawal. The container may take the form of a metal, square-sectioned tube 1, closed at one end 2, and of such dimensions as to receive a needle and engage closely about its square-shaped mount 4. An indentation 3 prevents the needle being inserted too far and the loop 8, at the end of a spring 6, passing through a slot 9, engages a reduced section 10 on the needle mount to prevent longitudinal movement. The needle is sterilized while in the container and is pressed on to the syringe before it is withdrawn therefrom, the absence of relative rotational movement facilitating this operation. In alternative forms, the metal case is of square cross-section only adjacent to the open end, the remainer being circular, and the retaining spring may be U-shaped so as to bear on both sides of the needle mount.

Preferably, the coils are equi-distant from each other and the spacing thereof is approximately twice that of the warp threads on which the device is intended to operate. In use, the tip of the coiled portion is passed under one of the warp threads and the coiled portion is then rotated and traversed across the warp threads either by hand or mechanically so as to pass alternately over and under consecutive warp threads. The straight portion may be formed with an eye, hook, or slot to receive the weft thread or the latter may be inserted between the warp threads by means of a separate member, e.g. a needle, bodkin, or shuttle. The straight portion may be made tapered and of greater thickness than the coiled portion. The tip of the coiled portion may be offset from the remainder thereof. The device may be used for setting up the warp in a loom.

Abstract: 568,911. Water - - waste preventing cisterns ; valve discharge. MYATT, J. T. Feb. 23, 1944, No. 3353. [Class 26] A flushing cistern 2 of the float-controlled inlet valve type is provided with an outlet flushing valve 4 which is normally open, but adapted to be closed, and permit the cistern to fill, by the pressure of the service water supply when admitted to the cistern and to be maintained closed by the water pressure until such time as the supply is shut off from the cistern, the outlet valve then opening to set up the flush. The outlet valve is contained in a casing 5 which connects the cistern outlet to the down flush pipe 6. The water supply pressure when introduced to a pressure chamber 7 forces the outlet valve against its seating 3. In this position a nut 16 on the base of tube 15 seals off the pressure chamber from the valve casing. Release of the outlet valve is controlled from a tread or from the seat of a W.C. which is connected by lever mechanism to the plug of the water supply cock. On shutting off the water supply, the pressure in the chamber 7 is released through a fine orifice 4b in the tube 15 and the outlet valve falls under the head of water in the cistern, permitting the flush to be set up.

Abstract: 563,967. Advertising apparatus. SANDOR, N. March 3, 1943, No. 3527. [Class 3 (i)] [Also in Group XV] Relates to translucent pictures, which are intended to be illuminated from the back and are divided into sections by partitions, so that different sections may be illuminated in sequence, as described in Specification 546,174, the pictures having black areas covering parts, such as the background of the design, which' never require to be illuminated. According to the invention, such pictures are produced by printing the design on one side of a translucent sheet of paper &c. and'the black areas on the other side, providing the black areas with lightcoloured lines 23, Fig. 2, to indicate the positions where the partitions are to be secured, and fixing partitions along the lines. The two sides of the sheet may be printed from identical blocks or stones, one being the reverse of the other and being modified to produce the black areas. The lines 23 may be formed by unprinted portions, or may be overprinted with a light-coloured ink. The design may be printed on the back of the sheet, so as to become visible on illumination. The picture is mounted on a glass sheet, and the partitions 16, 20, Fig. 3, which may consist of strips of cardboard bent to shape, are secured in position by adhesive tape. The back of the sheet and the partitions are sprayed with transparent varnish, which may serve to hold some of the partitions in place.
