Title: Improvements in or relating to thread uniting machines
IPC: D03J1/16
Filed: 1919-05-27
Abstract: 154,249. Imray, O., (American Warp Drawing Machine Co.). May 27, 1919. Knot-tying devices.-Relates to thread-uniting machines more especially for uniting the threads of two warps. In operation, the uniting-mechanism is continuously advanced and a threadplacing member or needle q moves from the position shown in Fig. 17 to the position shown in full lines in Fig. 14, and places the foremost separated and selected threads x<0> of the warps in the bight of a knotter-hook r as shown in dotted lines. The knotter-hook then makes half a revolution, the needle q moves a little to the left, and a tension rod s moves outwardly to put tension on the threads. As the knotting-device completes a revolution, a separating-hook r<7>, Fig. 16, which is normally Rush with the hook r, advances and the needle moves forwardly and laterally to place the threads between the hooks r, r' as shown in Fig. 16, the rod s being retracted at the same time to relieve the tension. The hook r' retracts and the strands are held between the hooks r, r<7> as shown in Fig. 17. The strands are severed by a rotatable severing-device t, and the knotting-device makes about another revolution, whereupon a loop-stripping arm u strips the loop from the knotter over the severed but clasped end, the threads being guided by a guide-plate v. Further movement of the stripper withdraws the threads from the knotter and clamps them against the carriage of the uniting mechanism. The tension rod s then gives a sharp outward stroke to tighten the knot, the stripper-arm moves out, and the parts resume the position shown in Fig. 14.

Title: Improvements in electronic control circuits
Inventor: BRADY THOMAS WILLIAM
IPC: G01D5/36
Filed: 1954-05-13
Abstract: 770,160. Determining direction of rotation photo-electrically. BRITISH THOMSONHOUSTON CO., Ltd. May 13, 1954 [May 13, 1953], No. 13369/53. Class 40 (3). In apparatus of the kind in which a movable screen, for example a rotating disc, is provided with an aperture through which radiation passes to a detector such as a.p.e. cell to produce pulses indicative of the motion of the screen, an auxiliary detector is provided which receives radiation in a time relation to the main detector which differs depending on the direction of motion of the screen so that the detectors together produce a signal indicative of the direction of rotation of the screen. An application mentioned is determining the speed of travel of a table forming part of a machine tool by counting impulses derived from the motion of a screen driven by the table. As shown, the direction of motion of disc 1 having a main aperture 2 behind which are two photo-cells 4, 5 and an auxiliary aperture behind which is a cell 6, is to be indicated. Cells 4, 5 and 6 are aligned radially but the apertures are spaced both radially and circumferentially. Thus for clockwise rotation cells 4, 5 are illuminated before cell 6 and for anticlockwise cell 6 before cells 4 and 5. A separate light source may be used for cell 6 or a single source with suitable optical system to illuminate all three. Circuit and operation.-Cells 4 and 5, illuminated simultaneously and before cell 6, are so connected that cell 4 delivers a negative pulse to the grid of a pentode 7 while cell 5 delivers a positive pulse to the grid of a pentode 8 through condensers 16 and 17 respectively. Neither valve conducts, however, owing to the absence of a positive pulse on the suppressor grids. When cell 6 is subsequently illuminated a positive potential is produced at its cathode which is applied to the suppressors of both valves but the original pulse produced by cells 4 and 5 has now ceased hence pentodes 7 and 8 both remain blocked. When the aperture passes cells 4 and 5, however, cell 6 remains illuminated hence a positive pulse is produced at the grid of valve 7 which conducts producing a negative output pulse at its anode while the grid of valve 8 is merely driven more negative and the valve remains cut off. During anti-clockwise rotation cell 6 conducts first making both suppressor grids positive so that when cells 4, 5 are subsequently illuminated producing respectively negative and positive pulses, valve 8 conducts producing a negative pulse at its anode. The negative pulses from pentodes 7, 8 representing respectively clockwise and anti-clockwise rotation may be fed into separate utilization circuits. For example, the negative pulses from pentode 7 may step a dekatron discharge in one direction while that from pentode 8 may step it in the reverse. A pair of flip-flop circuits may be used each actuated by one of the pulses,

Abstract: 560,237. Shaping glassware; uniting metals to vitreous material by heat. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., HARRIS, J. W., and SIMMS, C. H. Sept. 23, 1942, Nos. 13410/42 and 7554/43. [Class 56] [Also in Group XXXVI] Relates to a seal of the kind in which a number of metal wires, rods, or tubes pass through a wall of vitreous material and are arranged in a circle around the axis of a tube of which the wall is an extension. According to the invention, the seal is made by holding the wires 2, Fig. 1 (7554/43), in a block 1 which surrounds the vitreous tube 3, heating a part of the tube which projects beyond the block, and rotating the system so that the vitreous material, when softened, is flung outwards by centrifugal force and makes contact with the wires, the softened material then being shaped by pressing it between the block and a plunger 6, Fig. 3 (7554/43). Recesses 8 are made in the parts 1, 6 to form a bead around each wire. In another construction, a ring seal of the kind shown in Fig. 3 (13410/42) is formed by assembling glass tubes 23, 24, Fig. 2 (13410/42), coaxially in a block 21 of the shape shown and having recesses for the reception of the wires 2. The upper ends of the tubes are heated as the system rotates, and the soft glass of the tube 23 spreads outwards around the wires and into contact with the softened glass of the tube 24 which is prevented from spreading by a roller 9. Finally, the soft glass is pressed between the upper end 13 of the block and the lower end of plunger 25. Annuli 26, 27 shape the glass seal to the form shown at 10 in Fig. 3 (13410/42).

Abstract: 916,791. Semi-conductor devices. REGIE NATIONALE DES USINES RENAULT. April 21, 1959 [May 5, 1958], No. 13620/59. Class 37. Titanium dioxide is introduced into a ceramic mass by impregnation with a titanium salt, for example an alcohol solution of titanium tetrachloride. Before impregnation the paste is subjected to a baking process at a temperature between 600‹ and 1200‹ C., the temperature determining the porosity. The porous mass may be immersed in titanium tetrachloride and then in water for hydrolising tetrachloride. The impregnation may be limited to specific areas. An example is given in which a paste of 75% Al 2 O 3  and 25% SiO 2  is partially dried and then shaped by extrusion or rolling. Next a preliminary baking step is carried out at 900‹ C. in an oxidizing atmosphere. The plate is impregnated with titanium tetrachloride at the desired parts and then immersed in water. The plates are dried over a period of 24 hours, heated at 100‹ C. and baked at 1400‹ C. in an oxidizing atmosphere and 900‹ C. in hydrogen. Another method of preparation is described in which the baking step in an oxidizing atmosphere is omitted and heating in hydrogen and carried out in two stages at 1000‹ and 1400‹ C. A series of areas of different properties may be provided so that relative movement between the body and a pair of electrodes produces different electric effects and a ceramic with polarized conductivity to provide a rectifying effect may be produced.

Title: Improved method and apparatus for the continuous crystallization in vacuo of sugar solutions and the like
IPC: C13B30/02
Filed: 1946-05-06
Abstract: <PICT:0621797/III/1> <PICT:0621797/III/2> Sugar and like solutions are continuously crystallized in vacuo by feeding the solution to the first of a series of heated and interconnecting compartments to commence the evaporation and crystallization, and causing the resulting mass to flow continuously through the succeeding compartments in each of which the mass receives a continuous controlled additional supply of the solution, the displacement of the mass being effected by a difference in the level of the mass in successive compartments or by a difference of pressure between successive compartments. The solution fed to the first compartment may be nearly saturated, and may be seeded before or after it enters the compartment.  In the vertical apparatus shown, the annular chamber constituted by axial tube 1 and casing 2 is divided into five compartments 31-35 of increasing volume by means of radial partitions 3 extending from the bottom of the casing up to cap-member 4.  The tubular heater 6 may be common to all the compartments or may be itself divided into compartments.  The crystallizing mass in compartment 31 circulates through the heating tubes and annular chamber 8, and part of it passes through opening 9 into compartment 32; the transfer being guided by deflector 10 and partition 11. After flowing through the compartments, in each of which it receives a continuous flow of saturated solution through an adjustable cock, the mass is removed from compartment 35 through opening 12 in axial tube 1.  The steam pressure inside heater 6 is adjusted so as to properly associate the simultaneous evaporation and crystallization. In exceptional cases, it is possible to adjust the heating by acting on the proportion of incondensable gases in the upper portion of the heater.  The speed of evaporation as a whole is adjusted by providing the pipe connecting dome 5 to the condenser with an automatic vacuum regulator.  If the displacement of the mass is effected by pressure differences, these are controlled by adjusting the cross-sections of steam-outlets 13, 131 and 132.  In a modification, the heater 6 is secured directly to axial tube 1.  A horizontal apparatus is also described.

Abstract: <PICT:0872738/III/1> A plant for the continuous production of active silica sol by diluting commercial sodium silicate with a saturated solution of CO2 in water has an absorption vessel 5 connected by conduit 4, 15 with an ageing vessel 16, which has automatic means for controlling the residence time therein.  A flow regulating valve 13, controlled by the level of liquid in the absorption vessel 5, is disposed in conduit 4, and pump 1 injects a controlled amount of commercial sodium silicate into conduit 4 at a point sufficiently upstream from the valve 13 to permit mixing, and reaction of CO2 with caustic soda present before flow through the valve 13.  Water from spray nozzle 7 is saturated by CO2 from cylinders 12 in vessel 5, and the amount of CO2 is controlled by adjusting the pressure by control panel 9.  The aqueous CO2 mixes with the concentrated silicate solution pumped from head 1a of double-headed variable output metering pump 1, while head 16 controls water fed to absorption vessel 5, so that the ratio of silicate to aqueous CO2 is constant regardless of output.  The mixture flows through coiled tube 14 to complete reaction, and valve 13 to ageing vessel 16, being introduced into central mixing portion defined by helical baffle 17 enclosing agitator 20.  The counterweighed vessel 16 is mounted to allow vertical movement, so that increase in the weight of mixture in the vessel causes enlargement of outlet 18 relative to fixed valve member 19, with the result that the retention time in the vessel is constant irrespective of flow rate.  In an alternative ageing vessel the vessel is mounted on a counterweighed lever and balanced on a spring.
