Patent GB-1100407-A (GB)
Title: Silicon carbon dies
IPC: B21C3/18
Filed: 1965-11-23
Abstract: A SiC die is produced by depositing a layer of SiC from the vapour phase on to a substrate, removing the substrate, and finishing the SiC to the final die configuration.  The SiC may be formed by reducing an alkylsilane having a C:Si ratio of at least 1.75:1 (e.g. Me2Cl2Si, Me3ClSi, PrCl3Si, or a mixture of MeCl3Si and Me2Cl2Si) with H2 at 1150-1250 DEG  C., e.g. using a H2:silane ratio of 1:1 to 20:1.  The substrate may be tubular or rod shaped, and may be of Si, Ta, C, W, or alloys.  It is removed by sand blasting or etching, e.g. with HF-HNO3.  The substrate may be preformed to the internal configuration of the die and finished by polishing. Alternatively, the SiC coated rod may be cut longitudinally into sections, the substrate removed, and 3 of the sectors rounded and formed into the 2 legs and cross-bar in a reactor for further deposition of SiC.  These rods are then machined using diamond tools or electron discharge, and cut to length.  The SiC may be doped by incorporating N2, PCl3 or BCl3 in the gas.

Patent GB-1116671-A (GB)
Title: Workpiece shape control
IPC: B21B37/38
Filed: 1965-11-29
Abstract: 1,116,671. Rolling. WESTINGHOUSE ELECTRIC CORPORATION. 29 Nov., 1965 [10 Dec., 1964], No. 50511/65. Heading B3M. [Also in Division G3] In a system for controlling the shape of rolling mill rolls, the ratio of signals respectively dependent on forces applied between the rolls at different points is maintained constant by automatically controlling bending of the roll in dependence on the ratio. In Fig. 4, a strip 14 is rolled between crowned rolls 10, 12 having screwdown mechanisms 16, 17 applying forces at each end of the rolls and further hydraulic or electric motor actuators 22, 23 applying forces between the rolls so as to bend them to a required shape. Signals representing the screwdown and bending forces applied to the rolls are produced by inductive transducers 40, 42 and 44, 46 respectively. In Fig. 5, the signals from the screwdown transducers 40, 42 are averaged at 50 and compared with a signal, stored at 60, representing the screwdown force, determined experimentally, for which no bending is necessary to produce strip of the required shape. Any output from a difference circuit 56, representing additional screwdown force, is applied to a ratio circuit 80 where it is compared with the average of the signals from bending force transducers 44, 46. Any deviation of the ratio between the additional screwdown force and the bending force from a desired ratio results in an output from circuit 80 which is applied to a device 86 controlling the bending force actuators 22, 23 of Fig. 4 so that the ratio is corrected and the material maintained in a desired flat or slightly cambered condition. The difference between signals from X-ray gauges 90, 92 at the centre and edge of the rolled material is derived at 94 and any deviation from a value corresponding to the desired shape is effective, through a dead band circuit 96 if large enough, to correct the shape of the material by adjusting the desired ratio setting of circuit 80, e.g. by a motor-operated potentiometer. A timing device 64 associated with the roll drive controls a gate 98 to interrupt the control from the X-ray gauges for periods long enough to allow the effect of bending adjustments to be detected by the X-ray gauges. In one modification, signals from the force transducers are transmitted through follow-up servomotors which are controlled by magnetic amplifiers and operate potentiometers. In another modification, equality is also maintained between the screwdown forces by automatic adjustment of the appropriate screwdown mechanism under the control of detectors responsive to the larger force when they are not equal. Arrangements in which one or other of two bending forces applied in opposite senses is appropriately selected, and in which the bending force control system is combined with a known thickness control system, are described. Use of a digital computer is referred to.

The metal strip and mesh may be of W, Mo, Ta, or Nb, and the metal being evaporated may be Ag, Au, Cu, or Cr. An expansion fold may be put in at least one arm 10 to reduce thermal stresses.

Title: Process for recovering latex solids
IPC: C08F6/22
Filed: 1963-12-24
Abstract: Polymers are recovered from their latices by a process which comprises mixing the latex with an aqueous solution of an electrolyte until a substantially homogeneous, form - sustaining paste is obtained, forming the paste into one or more shaped units having a minimum cross-sectional dimension of 0.05 inch, and heating the shaped paste in an aqueous bath at a temperature at least as high as the heat distortion temperature of the polymer to harden and synerize the polymer particles.  Thereafter the hardened polymer may be granulated, washed and dried.  The process is particularly applicable to graft polymers of styrene and acrylonitrile on a butadiene rubber and to compositions of such polymers with styrene-acrylonitrile copolymer and styrene-alphamethyl styrene-acrylonitrile copolymer.

Abstract: 517,469. Workmen's time recorders. MOLDEN, J W., WEBBER, A. B., and MAGNETA TIME CO., Ltd. July 23, 1938, No. 21904. [Class 106 (iv)] Mechanism for recording the time at which various stages in a process are completed includes a time indicating element driven by ratchet mechanism from a clock or equivalent movement against the action of a spring, the ratchet mechanism being disconnected after each time recording operation thus allowing the spring to zeroize the indicating element by reverse movement. A synchronous motor 16 drives switch gear which sends current impulses at constant intervals to magnets 5 which .cause oscillation of frame 7 which drives time pointing wheels 11, 12 and 12a through ratchet gear. The frame 7 is also connected to an arm 19 which operates a ratchet 24 driving a wheel 25 connected to a further printing wheel 17. When the ratchet 24 and a retaining ratchet 29 are raised the wheel 17 is zeroized by a spring operated sector 31 acting on a wheel 30. The ratchets are raised by arms 37 and 40 operated by a bar 43 which is moved by latches carried on a arm 47 operated by a rocking shaft 48. When the printing wheel 17 has returned to zero a pin 35 on an arm 34 on the axle of the wheel operates an arm 57 to release a latch and allow the arm 43 to return to its original position. Co-operating with the printing wheels is a hammer 66 operated by a solenoid 68. The card on which the times are printed is slid into the machine between guides 73 and 73a and is pierced by a punch 75 driven from the shaft 48. Adjacent the punch a lever 78 engages the card which operates a relay switch 79 which operates the printing hammer 66 and also causes shaft 48 to be rocked by the solenoid 68. The switch is normally locked and is released for operation when lever 119 is depressed by the insertion of a card. An ink ribbon is associated with the printing wheels and is advanced at each printing operation by a ratchet drive.

An isotopic heat source is formed of a mixture of thulium 170 and thulium 171. The half power life of the source, i.e. the time required for the power to fall to half the initial power, is controlled by adjusting the ratio of thulium 171 to thulium 170.
