Patent GB-988416-A (GB)
Title: Process and apparatus for manufacture of highly crimped yarns
IPC: D02G1/02
Filed: 1963-07-16
Abstract: Yarn is crimped by passing it over a heating element e.g. a curved plate or tube, applying a false-twist which is set before untwisting and interposing an adjustable partial check or arrest of the twist e.g. by passing the yarn over three heated or cooled bars (one of which is displaceable) to which wetting agent and/or yarn lubricant may be applied.  The total false-twist is higher than the maximum twist normally regarded as compatible with the p  temperature of the heat treatment but the false-twist between the heater and the twist check does not exceed such maximum.

Title: Improvements in dosimeter charging devices
Inventor: ANDREWS THOMAS DESMOND HUDSON
IPC: G01T1/142
Filed: 1956-09-18
Abstract: 818,569. Two-part couplings combined with switches. DOWTY NUCLEONICS Ltd. Sept. 18, 1957 [Sept. 18, 1956], No. 28440/56. Class 38(1). A charging device for a dosimeter comprises a handle which includes means for generating a high voltage and which has a metallic bracket 2 secured to its upper end. A fixed pin 15 extends from the upper part of the handle and bends to extend axially along a cylinder 3, the termination of this pin including a small hollow metal cylinder secured by spokes to the pin so that contact may be made with the charging pins of dosimeters which are offset from the central axis. The hollow cylinder 3 enables light to pass into the charging end of the dosimeter, maximum passage of light being allowed by supporting the pin rigidly in a member 18 of transparent plastic material. The voltage source within the handle is controlled by a switch attached to the handle. The dosimeter 23 is of the type having a central charging pin 24 which is depressed inwardly to effect connection with the interior of the dosimeter. Firstly, the dosimeter is inserted into socket 7 whereby pins 24 and 15 are engaged. The eyepiece end of the dosimeter is then depressed relatively to the handle so that a moment is applied to socket 7 in arm 6 which is resisted by spring 8. This causes the socket to be frictionally engaged on the end of the dosimeter. Added force then moves the dosimeter and the arm 6 about pivot 5, causing depression of the charging pin of the dosimeter to make the necessary connection. Charging voltage is applied to the pin 15 so that the indicator is displaced beyond a predetermined position. The dosimeter is then slowly discharged until the predetermined indication is reached whereupon the charging pin is allowed to move outwardly to break the charging circuit.
