Patent GB-735396-A (GB)
Title: Vat dyeing
Filed: 1953-06-19
Abstract: Improved dyeings of vat dyestuffs on textile materials of cellulose acetate or other organic derivatives of cellulose are obtained by applying the vat dye as an aqueous dispersion of the vat acid, the dispersion also containing polyvinyl pyrrolidone, and then oxidizing the vat acid to the parent dye on the material. The dispersion may also contain a swelling agent for the cellulose derivative such as 2-butoxy-ethanol, 2-butoxyethoxy-ethanol, diacetone alcohol or triethyl phosphate. The dispersed vat acid may be maintained in the reduced state by the addition of a reducing agent, e.g. zinc or sodium formaldehyde sulphoxylate or thiourea dioxide.  Oxidation may be effected by hydrogen peroxide, sodium perborate or acidified sodium nitrite solution and development of the dyeing may be assisted by hot soaping and/or steaming.  The process may be effected by the pad-dyeing or printing technique and the dispersion may contain thickeners such as gum tragacanth or methyl- or hydroxyethyl-cellulose.  The vat acid dispersion may be made by reducing the vat dye to the soluble leuco form in an aqueous alkaline medium and then adding an acid, e.g. acetic, formic, oxalic or citric acid.  Alternatively, the dye may be vatted with an aqueous reducing agent in the presence of an amine such as hexamethylene diamine, cyclohexylamine, pyrrolidine or ethylene diamine.ALSO:An aqueous dispersion for use in the dyeing of cellulose derivative textiles (see Group IV (c)) comprises a vat acid and polyvinyl pyrrolidone.

Title: Power hacksaw
IPC: B23D49/02
Filed: 1972-04-14
Abstract: 1392357 Hacksaws A STOLZER [trading as KARL STOLZER] 14 April 1972 [29 June 1971] 17298/72 Heading B5L A hacksaw machine comprises a jaw 9, Fig. 1, for clamping a workpiece 12 against a table plate 13 of a machine pedestal 1, and a saw frame carriage 6 which carries a rectilinearly guided reciprocating saw frame 15 and a crank drive therefor, and which is translatable with weight compensation vertically relative to the machine pedestal 1 along guide means under the control of an hydraulic system. The hydraulic system comprises a piston 30 connected to the pedestal 1, Fig. 5, a cylinder 8 secured to the carriage 6, a charging piston 52 communicating via a pressure valve 62 with a chamber 31 of the cylinder 8, and via a valve 63 with a container 61 for hydraulic pressure fluid, an outlet 34 from the chamber 31 communicating via an adjustable throttle valve 36 with the container 61, and a pump 51 in communication with the chamber 31. The pump 51 and piston 52 are driven by eccentrics 49, 50 respectively mounted on the shaft of the crank drive of the saw frame. The arrangement is such that pressure fluid from piston 52 enters the chamber 31 to feed the saw blade towards the workpiece during a cutting stroke and the operation of the pump 51 is such as to raise the saw blade from the workpiece during its idle stroke. As described the carriage 6 is guided by vertical columns 2, 3, 4. The column 4 acts as a workpiece abutment and the column 3 carries the piston 30. The space 27, Fig. 5, above the piston 30 in the cylinder 8 is under constant pressure from a reservoir 59 so as to tend to urge the saw carriage upwardly and thus act as the weight compensation. The throttle valve 36 determines the maximum pressure that can be applied by the blade to the workpiece and is controllable by a spiral cam, one limit position of which releases pressure from the chamber 31 so that the saw carriage can be raised on completion of a cut.

Title: Improvements in and relating to apparatus for detecting and determining the direction of wave energy
IPC: G01S3/14
Filed: 1920-06-25
Abstract: 146,188. Steward Davit & Equipment Corporation, (Assignees of Hayes, H. C.). June 25, 1919, [Convention date]. Locating subaqueous sounds.-A number of receivers are arranged in a circle and means are provided either for delivering the sound from any two opposite receivers to the two ears, to enable direction to be determined by the binaural sense, or for adding the effects of the various receivers in phase as regards sounds from a given direction, while sounds from other directions give interfering components and a weaker resultant, or the two methods may be combined. In the form shown diagrammatically in Fig. 1, microphones 1 - - 36 are arranged in a circle and connected through transformers to the segments 1<d> - - 36<d> of a commutator. By means of brushes 1<e> - - 14<e>, fourteen of the microphones, in two groups of seven, are connected to telephone receivers 1f - - 14f, which deliver their sounds to two tubes T terminating in the two ear-pieces of a stethoscope S, Fig. 5. The spacing of the telephones along the tubes T is arranged so that for sounds arriving in the direction of the arrow N the effects of all the microphones reach the ears in phase with oneanother, while sounds from any other direction produce effects which are out of phase. The brushes 1<e> - - 14<e> are rotatable (being connected to the telephones 1<f> - - 14<f> through slip-rings not shown in the Figure) so that the direction of maximum response can be shifted round the compass at will. The binaural sense is also brought into play, the sound appearing to move from left to right of the listener's head, or vice versa when the commutator is moved through its correct position. If the two stethoscope tubes are joined, as shown in Fig. 6, the binaural effect disappears and direction is determined entirely by estimation of maximum intensity. The key BS which controls the microphone feed circuit is shunted by a condenser, to protect the microphones against packing when the circuit is opened. The circle of microphones may be about eight feet in diameter and is generally at a distance from the rest of the apparatus; it may be on the bottom of the sea, or hung from a moored vessel, or placed in an oil or water tank in a ship. The rotary commutator may be omitted, the microphones themselves being rotated to the position of maximum response. Phase-compensation may be effected by time-consuming electric circuits instead of by the air-tubes T. Specification 146,190 is referred to.

Title: Apparatus for controlling the current of electrical devices
IPC: H01F13/00
Filed: 1970-04-13
Abstract: 1312971 Control systems for demagnetizing magnets A K LITTWIN 13 April 1970 [14 April 1969] 17399/70 Heading H2H A circuit arrangement for use in the demagnetizing process of a device such as a magnetic chuck comprises solid state devices, the arrangement being such that the direction of current through the demagnetizing winding may be reversed without physically disconnecting the circuit. The control circuit, which is described in detail in the Specification, includes two pairs of back-to-back thyristors connected between a supply rectifier and the chuck winding, the firing of the thyristors being controlled by secondary windings of transformers, the primary windings of which are controlled by the contacts of relays so as to be alternately energized and thereby alternately energize the chuck winding. The degree of magnetization in each step is controlled by a system of capacitors, the voltage across which is reduced in each successive step. When the voltage across the supply rectifier reaches the voltage of the capacitor system, the demagnetizing step is terminated and, after a time delay, the relays operate to control the alternate pair of thyristors to reverse the energization of the chuck winding during the next step in the demagnetization process, the capacitor system being effective during this step to reduce the energization from the value during the preceding step. The process repeats until the energization of the chuck winding is substantially zero. Control means are incorporated whereby the chuck winding can be reduced to zero in two steps if desired.

Filed: 1919-07-15
Abstract: 152,738. British Thomson - Houston Co., (General Electric Co.). July 15, 1919. Wire.-Flat filaments are made by feeding a circular filament over an anvil where it is subjected to rapid hammering. A grooved anvil may be used to determine the thickness of ribbon produced, or a flat anvil may be used, in which case the thickness depends upon the rate of feed, the strength of hammer blow, and the working temperature. In the machine shown in Fig. 4, the filament is drawn by a motor-driven wheel 19 from a braked supply spool 20 and passes over a notched guide 22 and under an anvil 8, where it receives blows from cylinders 13 mounted on pins 12 mounted loosely on the circumference of an eccentrically rotated disk. The filament is heated before reaching the anvil by a burner 23. The filament passes by a pulley 24 and weighted pulley 26 to a collecting spool 25 which is either of greater diameter, or driven faster than the spool 20 to take up the increase of length due to hammering. The anvil 8 is adjustably mounted in slotted standards 4, and may be rotated to prevent wear. Fig. 6 shows a groved anvil comprising washers 10 separated by one of smaller diameter 8 and mounted on an arbor 7.
