Title: Treatment of cellulosic textile materials
Inventor: SAUSE ROBERT
IPC: D06P3/68
Filed: 1955-05-27
Abstract: Cellulosic textile materials such as cotton, viscose and acetate rayon are given an affinity for basic dyestuffs, such as those that contain thiouronium salt groups attached through methylene linkages to aromatic nuclei, by treating them under aqueous alkaline conditions with one or more non-dyestuff compounds containing at least one 1 : 3 : 5 triazine ring the carbon atoms of which carry as substituents two halogen atoms and a residue of a primary or secondary amine bound via the nitrogen atom thereof and containing at least one negatively charged solubilizing group, e.g. a carboxylic or sulphonic acid group. The alkali, e.g. sodium hydroxide or carbonate, may be applied before, after or together with the triazine derivative.  The triazine compounds, many of which are specified, may be prepared by reacting a cyanuric halide with a primary or secondary amine containing a solubilizing group.  The amine may be a diamine, in which case a diprimary condensation product may be formed. Numerous examples are given in which the treated fabrics are subsequently printed with basic dyestuffs.  Specifications 342,167, 576,270, 587,636, [all in Group IV], 613,980 and 794,181 are referred to.

Filed: 1935-05-30
Abstract: 459,231. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. May 30, 1935, Nos. 15710 and 15711. Convention dates, June 1, 1934 and May 16, 1935. [Class 39 (i)] [See also Groups II, XI, and XV] In subdividing a metal layer on an insulating base into minute, insulated particles as in forming the photo-electric mosaic screen of an iconoscope for television, the metal layer is so thin that it is transparent and breaks up into the particles on heating to about 400-450‹ C. in a suitable gas, preferably in the presence of oxygen. Mica bases are not damaged by such heating, but polished glass or ceramic bases may also be used. The layer is of silver or copper produced by cathode atomization, condensation in vacuo or chemically and is À1-À01, preferably À03-À05 Á thick. The layer is heated subsequently to, or simultaneously with, its deposition. The layer 2 on a mica base 3 may be heated for 15-20 minutes by radiation from a plate 1 heated by eddy currents by a high-frequency coil 4. The final metal particles are about 1 Á in size. The effect of the thickness of the metal layer on the temperature at which it subdivides is discussed. Methods of subdividing the layer by engraving or chemically or by heating to 800-1000‹ C. in vacuo or indifferent gas or by alternate oxidation and reduction are referred to ; in the last method, the silver layer is heated alternately in oxygen and vacuo or subjected to glow discharges alternately in oxygen and hydrogen at a pressure of 1 mm., the silver layer forming the cathode or being arranged behind a grid - shaped cathode. Specification 407,521 is referred to.

Title: An automatic electric circuit breaker for equilibrated polyphase electric circuits
IPC: H01H71/24
Filed: 1921-06-07
Abstract: 185,514. Balducci, A. June 7, 1921. Automatic circuit-breakers for balanced polyphase circuits have a single tripping-coil 1 in one phase which actuates armatures in accordance with predetermined maximum and minimum values of current to interrupt all the phases. This interruption is effected by a multi-polar switch having bridging-contacts 13 secured on a spindle 12 with a crank 12<1>, the switch being closed by an operating-handle 14 with an arm 14<1> which, bv abutting against the crank 12, carries the switch to its closed position, in which it is retained against an opening-spring by a pivoted catch 9 pressed by a spring 17 to engage a recess 10 in a sector 11 on the shaft 12. The trip coil 1 has a core with pole-pieces 2, 2<1> and pivoted armatures 3, 3<1> for minimum and maximum interruption respectively. The former when allowed to drop owing to insufficient current in the coil 1 engages, by an arm 6, a collar 7 on a sliding rod 8, thereby releasing the catch 9 and allowing the switch to open the circuit. The armature 3, when attracted to the pole-piece 2<1> by reason of current above the predetermined maximum flowing in the the coil 1, depresses a rod 18, passing through the core. against the action of a spring 15. The rod 18 rocks a bellcrank lever 16 which in turn depresses the rod 8 and releases the catch 9, allowing the switch to open. In order to prevent attraction of the armature 3<1> on the initial rush of current arising when the switch is first closed, the handle 14 is provided with a hooked lever 4 engaging a similar lever 5 attached to the armature 3<1> the handle 14 being held in its final position until the current subsides to a normal value.

Title: Device for picking up printed sheets on high-speed presses
Inventor: HOFFMAN ROLAND
IPC: B65H29/04
Filed: 1965-04-14
Abstract: 1,086,965. Delivering sheets. DRUCKMASCHINENWERK VICTORIA VEB. April 14, 1965, No. 15928/65. Heading B6H. In a stop-cylinder printing press wherein sheets 11 are fed to an impression cylinder 2 the sheets 11 are picked up by one of three or more sets of grippers 8, 9, 10 mounted on a chain 7 driven at a speed which is increased and decreased relative to the impression cylinder. The diameter of the chain-wheel (6) driving the grippers is greater than the diameter of the impression cylinder 2 but less than one and a half times the diameter thereof. The chain 7 is driven from a sprocket-wheel 6 which is connected to a spur gear 4 in engagement with a gear 3 on the ends of the impression cylinder 2 by means of a crank and cam-roller arrangement 5, 27, or by a single couple 5, Fig. 1. At the point P the impression cylinder 2 and the chain 7 run synchronously so that the sheet is easily transferred. As shown in Fig. 1, gripper 8 has removed a sheet from the cylinder 2. Gripper 10, however, is further away from the next gripper 15 on the cylinder 2 so the gripper 10 is speeded up by the eccentric mounting of the cam groove for the roller 27 with respect to the centre of of the gear 4. -Thus as the wheels 4 and 6 rotate, the distance of the roller 27 from the axis of gear 4 changes and this turns a lever 24 which moves the couple 5 and accelerates the gripper 10 which arrives at the point P at the same time as the gripper 15. The sheets are deposited on a conveyer travelling in the reverse direction to the sheet at the time; it is released from the chain 7 by a cam 20 which opens the grippers.

Title: Improvements relating to monofuel reaction chamber apparatus
Inventor: TABBERER GEORGE
IPC: F02K9/68
Filed: 1960-05-09
Abstract: 899,913. Generating combustion products under pressure. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 19, 1961 [May 9, 1960], No. 16334/60. Class 51 (1). [Also in Group XXVI] The invention relates to apparatus for producing a flow of gaseous working fluid by the decomposition of monofuel within a reaction chamber, the gaseous fluid being utilized for example in a turbine starter for a gas turbine engine. The apparatus is shown in the Provisional Specification drawing and comprises a reaction chamber 1 which is supplied with monofuel from a tank 2 through ducting 3 which includes non-return valves 4, 5. Upon starting, air under pressure is supplied from a cartridge 9 through a non-return valve 8 to a shuttle valve 7. The valve is shown in Fig. 1 and comprises a body portion 20 containing a valve member 21 having an enlarged head 22 at its upper end and an enlarged head 23 secured at its lower end, the valve member having a longitudinal bore 24 and a transverse bore 25. The valve body portion 20 comprises a passage 26 which is connected to the air cartridge, a passage 29 which is connected to the reaction chamber 1, an outlet 28 connected to the low-pressure side of a pressure intensifier 9<SP>1</SP>, and a vent 30 open to atmosphere. The air supplied to the passage 26 at starting causes the shuttle valve 21 to rise until the head 23 abuts the shoulder 31 of the valve casing, and air then passes through passage 29 to the reaction chamber 1, also through outlet 28 to the pressure intensifier. The intensifier causes monofuel in the line 3 to pass into the reaction chamber through the atomizer 6, the monofuel mixing with the air supplied through the valve 7 and the mixture being ignited by a spark device. The pressure in the reaction chamber increases and so the shuttle valve 21 is caused to move downwardly, against the reducing pressure of air from the cartridge, to the position shown in Fig. 2 so cutting off the air supply which is vented to atmosphere. The pressure of gases within the reaction chamber is simultaneously applied to the low-pressure side of the pressure intensifier 9<SP>1</SP> through passage 29 and outlet 28 so maintaining the supply of monofuel through the line 3 and main fuel valve 10 to the reaction chamber, the valve 10 being opened by the pressure developed in the reaction chamber. An electrical control unit 11 is provided, operation of the unit causing air to be released from a cartridge 9, energizing the ignition device 14 and causing the by-pass valve 15 in the monofuel supply line to close. The high-pressure side of the pressure intensifier contains sufficient monofuel to enable a single starting operation to be performed. A stand-by cartridge 16 containing a deflagrant may be provided. Specifications 784,121, 787,572 and 816,752 are referred to.
