Abstract: 1496854 Injection moulding grooved articles ANTON ANGER MASCHINENBAU GmbH 22 July 1976 [29 July 1975 10 Oct 1975] 30573/76 Heading B5A A method of producing grooves in containers, ducting or sleeves 4 comprises introducing synthetic material into a mould 1 having a multi-part core 3, heating the material at least in the region where the groove is formed so that the material displays resiliency and withdrawing the part 7 of the core 3 axially of the latter whilst the material is resilient so that the groove is elastically deformed and then recovers its moulded shape. As shown, the grooved sleeve is injection moulded from PVC in a split mould 1 having a three part core 3, part 8 of the core defining the outer contour of the groove 5. To withdraw the parts 7, 8, part 8 is slid along the main body of the core 3 by a drive acting on a flange 15 until a stop 16 engages a stop 17 on part 7 to thereby withdraw the latter and hence flange 13 from groove 5 as the part 8 is further withdrawn. The part 7 may be provided with a shoulder 18 for supporting the moulding after withdrawal of the core part 7 until the moulding has cooled sufficiently. The part 7 and/or the part 8 may be provided with cartridge heaters 22. The part 7 may be provided with air outlets so that air may be introduced between the core and moulding to facilitate parting. The core parts may be held in engagement during moulding by either a semi-circular wedge 12 (see Fig. 1, not shown) or a hydraulic device 24 (Figs. 5, 6, not shown).

Abstract: Peracetic acid is stabilized with an acid of the general formul <FORM:0917495/IV (b)/1> and/or soluble salts thereof, n being at least 1.  Specified acids are those wherein n is 1 or 2, and also commercial "polyaminocarboxylic acid".  The solutions are used for bleaching (see Group IV(c)).ALSO:The invention comprises a bleaching solution containing peracetic acid and an organic acid of the general formula <FORM:0917495/IV (b)/1> and/or soluble salts thereof, n being at least 1.  The preferred acid is diethylene triamine penta-acetic acid, other specified acids being triethylene tetramine hexa-acetic acid and "polyaminocarboxylic acid".  The solution is prepared by mixing together acetic anhydride and hydrogen peroxide and adding to the mixture the organic acid and/or salt thereof.  Preferably the solution also contains sodium acetate, this preferably being initially added to the hydrogen peroxide.  The solution preferably has a pH of 4.5.5.5 and may be adjusted to this value by the use of, for example, acetic acid, sodium carbonate, ammonia or tetrasodium pyrophosphate.  The products to be bleached, which may be fibres or fibrous or non-fibrous materials, may be treated with a pre-formed bleach solution or the solution may be prepared in situ, the bleach bath normally being heated, e.g. to 75 DEG -80 DEG C. for nylon and to 85 DEG -90 DEG C. for cotton.

Abstract: 908,031. Radar simulators. COMMUNICATIONS PATENTS Ltd. Aug. 16, 1960 [Sept. 10, 1959], No. 30889/59. Class 40 (7). A radar simulator capable of simulating the effect of " window " comprises a C.R.T. 10 providing a P.P.I. raster on its fluorescent screen which is focused on to a photo-multiplier 13 through two spaced sheets of light polarizing material; e.g. " Polaroid " (Registered Trade Mark), arranged with their respective axes of polarization at right-angles, a dispenser 32 being located between the Polaroid sheets 22 and 23 for releasing on to the lower Polaroid sheet 23 particles of " light-active " material capable of rotating the plane of polarization of light incident thereon from the screen of the C.R.T. 10 so that each particle causes some light to pass through the lower Polaroid sheet 23 on to the photo-multiplier 13 to produce a corresponding electrical signal which is applied to a display C.R.T. 12 scanned synchronously with the C.R.T. 10. The " light-active " material may comprise caster sugar, finely-ground quartz, fine river sand or finely-divided mica flakes. For simulating a radar carried by a fighter aircraft intercepting a target dropping the window, the C.R.T. 10 together with the upper Polaroid sheet 22 and a lens 18 and filter 37 are moved by a gantry 20 in accordance with the assumed movement of the fighter, the scanning coils 9 of the C.R.T. 10 being orientated by a motor 29 in accordance with the assumed heading of the fighter, and the dispenser 32 is moved by a gantry 30 in accordance with the assumed movement of the target. A target image is produced by a quartz crystal (not shown) carried by the target gantry adjacent the dispenser 32. The dispenser 32 is operated to release the " light-active " particles by rotation of a shaft 33 controlled by a " window release " relay 35. Disposal of the window after release is simulated by vibrating the lower Polaroid sheet 23 by a vibrator unit 24 and wind drift is simulated by tilting the sheet 23 about orthogonal axis by means of motors 65 and 71.

Abstract: 1,237,743. Relieving device for telemotor system. L. G. NORDIN. June 28, 1968, No.30912/68. Heading F1P. A device for connection between the twin lines of a double-acting telemotor system comprises a housing C having opposed chambers 49, 50 connected to the lines and each containing a respective movable member 53 or 54, the members having disposed therein normally closed valves 61, 62 which open simultaneously on occurrence of an equal pressure in both lines. The members 53, 54 are slidable in the chambers and the valves 61, 62 are urged by springs to the closed position. If the pressures in the lines increase, due to liquid expansion, the members move together and pins 64, 65 on an intermediate member 63 open the valves 61, 62 to allow liquid to pass from the lines into a pressure reservoir D. The reservoir D is fitted by lifting a spring- loaded piston 45 to draw liquid there into from a container 40 past a non-return valve 42. Each movable member 53, 54 also includes a lowpressure valve 57 or 58 for admitting liquid to the lines when the pressure therein is low and an over-pressure valve 59 or 60 for relieving excess pressure in the lines.

Abstract: 485,002. Thermal switches. ELEXCEL, Ltd., and WICKERSON, S. A. Nov. 12, 1936, No. 30940. [Class 38 (v)] A thermal cut-out for an electrically heated vessel, such as a kettle, comprises a metal peg 23 fixed to the bottom 10 of the vessel anc having soldered to it a sleeve 24 terminating in a pin 25 on which is pivoted an arm 12 which carries a pin 15 which in the normal position bridges contacts 16, 17 in series with the heating elements 30, 31. The arm 12 is biassed towards the off position by a spring 27, but is normally held in the on position by a spring 28 which closely embraces the sleeve 24 and one end of which engages the arm 12. The spring 28 is wound in such a direction that when the arm 12 tends to move to the off position, the spring grips the sleeve 24 but allows movement towards the on position due to unwinding of the spring. On overheating of the vessel the soldered connection of the sleeve 24 and peg 23 melts and allows the sleeve to rotate and the arm 12 to move to the off position. After the solder has set, the arm 12 may be moved by a projection 13 to the on position.

In a thrust bearing for a rotary element in a housing, an independent thrust-plate is provided between the housing and an end-plate attached thereto. The housing may be made of light alloy and the thrust-plate may be made from steel sheet, sintered iron, sheet bronze, bearing material on a metal backing and from synthetic plastics material such as nylon which may be impregnated with molybdenum disulphide. The rotary element may have thrustpads which engage the thrust-plate and which are made from materials similar to those used for the thrust-plate. In an embodiment, the thrust-plate 18 of an oil-pump is abutted by rotors 1-3 which are in meshing engagement, the rotor 1 being driven by a shaft 4 connected thereto. A chamber 8 of the housing contains the rotors and is connected to an inlet 9. An outlet chamber 10 communicates with an outlet 11 through a valve 12, having a spring-loaded member 13, which operates at a predetermined pressure. The valve 12 also serves to by-pass oil from the chamber 10 to a connection 14 on the housing 5, when the delivery pressure is reached. A by-pass passage 15 in the housing 5 communicates with the chamber 10 and is normally closed by a set-screw 16 screwed into the housing. When it is necessary to bleed the pump, the set-screw 16 is replaced by a smaller set-screw and the connection 14 is plugged. A gauge connection 17 is provided in the housing.
