Title: Improvements in or relating to apparatus for selecting and separating threads of a warp
IPC: D03J1/14
Filed: 1962-10-03
Abstract: 965, 732. Separating threads from warps. T. D. NOONE WOVEN PRODUCTS PROPRIETARY Ltd. Oct. 3,1962 [Oct. 5,1961], No. 37443/62. Heading D1M. A device for selecting and separating the end thread from a warp sheet held in a clamp 108 is mounted on a carriage which moves until a rod 50 contacts the warp. Brushes 82 then grip the end few threads and a plate 77 moves towards the warp and at the same time turns so that the end thread is released from lease cords 100, 101, the remainder of the threads being pushed away by lease sleeves 78 mounted on the plate 77. Gripper fingers 48, 49 then move forward vertically above a shaft 27a to grip the thread, and thereafter the shaft 27a is rotated through a right angle so that the gripper fingers move the thread to a position from which it may be drawn into a heald 107. This movement is sufficient to pull the thread from the clamp 108 and also to depress a trip 87 to stop the motor which through suitable gearing controls the entire device.

Title: Apparatus for measuring high temperatures and method of manufacturing same
IPC: H01L35/22
Filed: 1959-11-05
Abstract: 901,177. Thermo-couples. CARBORUNDUM CO. Nov. 5, 1959 [Nov. 10, 1958], No. 37526/59. Class 37. In a thermo-couple, one element is formed by a rod 11 of SiC which is thermo-electrically negative with respect to graphite, and the other element comprises a closed ended tube 12 of SiC which is thermo-electrically positive with respect to graphite. The elements are arranged concentrically in a cup-shaped base 10, being held therein by screws 14, 17, and the rod being pressed axially against the end of the tube by a screw 20. The rod element may alternatively be made of graphite. Thermo-couples are also made by abutting rods of SiC having dissimilar thermo-electric characteristics, or by clamping such rods in a mutually insulated manner so that one end of each rod may be immersed in molten metal the temperature of which it is sought to determine. Making sic elements.-Tube 12 is made of SiC having a density of at least 3 g./cm.<SP>3</SP> in accordance with the process of Specification 901,176, which involves compacting a homogeneous mixture of granules of SiC and a carbonaceous material, such as graphite, with a carbonisable material such as phenol-formaldehyde temporary binder, gum tragacanth and dibutyl phenyl-phenol sodium disulphonate, extruding the mixture in tubular form, and firing until the temporary binder sets. The temperature is then further increased to between 1850 C. and the decomposition temperature of SiC while the tube is maintained in an inert atmosphere in contact with free Si in greater quantity than is required to react with the available C. Alternatively, a tube of dense SiC is made by the process of Specification 828,211 which comprises the steps of forming a mix of high purity green SiC of differing particle sizes with phenolic resin binder and pine oil to make a closed ended tube which is oven-dried and fired at 2300 C. to recrystallize the SiC. This tube is soaked in furfural or furfuryl alcohol or an organic resinous compound which is then carbonized by exposure to hydrogen chloride vapour; alternatively, the tube is impregnated with carbon by being heated in the presence of a carbonaceous gas, e.g. methane or acetylene. Finally, the tube is heated in the presence of free Si or SiN. SiC of this density is substantially impervious to gases. The rod 11 is formed by recrystallizing high purity green SiC granules mixed with a temporary binder and pine oil.. In another example, a rod of SiC having a positive characteristic relative to graphite is made by extruding and recrystallizing a mix containing a grade of SiC having a minimum content of 97.00% by weight SiC, a maximum amount of 0.75% by weight free Si, and a minimum of 98% of black particles. Rods having negative characteristics comprise a grade of black SiC having a minimum SiC content of 96.5% by weight and maximum contents by weight of free C, 0.75%, H 2 O, 0.5%, free Si, 0.75%, or a green SiC having a minimum SiC content of 97.5% and not more than 0.25% free Si.

In a device for perforating a tape in code for controlling a typographical composing machine, a conventional " Linotype " (Registered Trade Mark) keyboard is used to control the assembly of counter-weights, cams and driving rollers which is used in a composing-machine to control the matrix escapements, said assembly being modified in that the escapement-actuating rod is utilized to control electrical contacts in an electrical system for energizing electromagnets operating at least seven punches, and in that the usual cam is modified to have an actuating period of between 1/3000 and 1/30 second, having an actuating peripheral surface projecting over an angular distance of 5.4-60 degrees. The rod 8, Fig. 2, controls contacts 10, 11 under control of a cam 6a, Figs. 2 and 3, having an actuating surface 6d instead of the usual surface 6b shown in chain lines. The magnets E1-E10, Fig. 6, are arranged approximately in a circle surrounding the punches. The code punches are actuated by magnets E1-E7. Magnets E9 and E10 produce tape-feed perforations in every cycle, and magnet E2 operates the tape-feed mechanism. Magnet E8, Figs. 6 and 7, controls contacts V, W in the electrical system, Fig. 5 (not shown), and also oscillates an arm 24, which on moving upwards causes a pawl, 30, to index a ratchet wheel 31 on the shaft of a pin-roller feeding the tape. A roller-pawl 33 engages a ratchet wheel 32 to hold the tape in register during punching. A button is provided for manual adjustment of the tape. The electrical system includes means to produce repetitive energization of the magnets E8-E10 to feed the tape without code signals, and a manual switch to produce continuous feed of the tapes.

Abstract: 1318722 Crystalization apparatus WHITING CORP 14 Aug 1970 [29 Sept 1969] 39206/70 Heading BIG Apparatus for crystallization comprises a vessel for containing a slurry of crystal particles and mother liquor, means for producing supersaturation in the mother liquor, means to circulate the slurry along a predetermined flow path in the vessel and to keep the crystal particles in suspension, means to remove a stream of slurry containing only crystals which are smaller than a predetermined size and means whereby both the size of the crystal particles and the volume of slurry in this stream may be controlled independently of each other. In the embodiments described, the supersaturation is produced either by cooling the slurry or by the use of a vacuum over the surface of the slurry to remove solvent. The circulation of the slurry is produced by means of a propeller or by a pump. In all embodiments a portion of the slurry is segregated into a quiescent zone out of the main circulation stream, this quiescent zone serving as an elutriation chamber where the fines are separated from the coarser crystals. The stream of fines is removed from the upper portion of the elutriation chamber and is then either warmed to dissolve the fines and reintroduce them into the apparatus, or removed and stored. This fines stream is removed by means of a variable delivery pump, the speed of which governs the flow in the elutriation chamber and hence the size of crystal particles removed. It is an essential feature of this invention that more than one elutriation chamber is provided. This feature allows the volume of slurry removed as fines and the size of the fine crystals to be controlled independently of each other, as the chambers may be of different sizes and may be used individually or together. In the apparatus illustrated in Figs. 1 and 2, a main vessel 12 is joined to cylinder 16, so that portions 17a, 17b of the cylinder 16 extend into the vessel 12. A draft tube 23 is supported inside the cylinder and has a propeller 25 at its lower end. This propeller forces the slurry in the direction shown, leading to the quiescent zones 29, 31, which serve as elutriation chambers. The fines are removed through outlets 32 and 33 and either destroyed, recycled or stored. Partitions 27, 28 separate the annular space between vessel 12 and cylinder 16 into the elutriation chambers 29, 31.
