Title: Process for the production of diamino-dihydroxy-anthraquinones
IPC: C09B1/503
Filed: 1964-03-17
Abstract: 1,5- or 1,8-diamino-4-hydroxy-anthraquinone and b  derivatives thereof are oxidized to give 1,5- or 1,8-diamino-4,8- or 4,5-dihydroxy anthraquinones.  The oxidation is carried out in concentrated sulphuric acid or oleum and at temperatures of 0-100 DEG C.  Oxidizing agents used are persulphates, chromium trioxide, lead dioxide and manganese dioxide.  The oxidation yields in part a quinone imine which is reduced by the addition of a reducing agent, e.g. bisulphite, haloacids or iron to the acid solution. The b substituents include halogen atoms, hydroxy groups, nitro and amino groups, alkyl and alkoxy groups.

Abstract: 1420383 Seaming non-metallic sheet material IWEMA FORPACKNINGS AB 7 March 1973 [29 March 1972] 11199/73 Heading B5K A tool for cutting and welding thermoplastic sheets 15, 16 comprises two opposed jaws 1, 2, cutting means 3 in the jaw 1 and a heating body 10 in the jaw 2 which has an inset piece 11 having a groove 12 therein to receive the means 3 during its operation, the surfaces of the piece 11 which face the jaw 1 being contained in the same plane, welding surfaces 14 being formed on the jaw 2 on each side of the piece 11 which is made of a material of lower heat conductivity than the material of the jaw 2. As shown, the means 3 comprises a knife movable by a pneumatic cylinder 5. The jaw 1 is provided with silicone rubber inserts 7 to prevent the sheets 15, 16 adhering thereto. The jaw 2 may be made from aluminium and comprises two parts 8, 9 with the body 10, e.g. a resistor element, therebetween. Preferably, the piece 11 is made of asbestos or polytetrafluoroethylene and is of U- or V-section. To regulate the heating effect, thermistor sensors 17 may be provided. A tube 18 having an outlet 19 for cooling air is provided on each side of the jaws 1, 2. In operation, articles to be packaged are forwarded horizontally individually between the two jaws 1, 2 to displace a vertical thermoplastic sheet to form sheet portions 15, 16 behind the articles. The jaw 1 is lowered by a pneumatic cylinder with the knife 3 retracted. When the jaw 1 is positioned adjacent the portions 15, 16, the knife 3 commences its downward movement. The tubes 18 participate in the downward movement of the jaw 1 during the last portion of this movement. After cutting and welding, the tubes 18 move upwardly with the jaw 1 for a short distance to separate the portions 15, 16 from the jaw 2. Simultaneously, cooling air is momentarily sprayed through the outlets 19.

Title: Improvements in or relating to the manufacture of rubber derivatives
IPC: C08C19/12
Filed: 1933-04-18
Abstract: Stable chlorinated rubber is obtained by emulsifying a solution of unstable chlorinated rubber in water and an alkaline substance such as an alkali or alkaline earth hydroxide, carbonate, bicarbonate, or acetate.  With substances weaker than alkali metal hydroxides, the temperature must be 40 DEG  C. or higher.  The stable chlorinated rubber may be isolated by precipitation water heated to a temperature above the boiling point of the solvent. According to an example 32,3 kg. of an 11,2 per cent solution of chlorinated rubber in carbon tetrachloride is heated to the boiling point of the solvent with stirring.  300 gm. of sodium carbonate in 5 litres of water is gradually added and the whole is stirred for 6-8 hours at 80-85 DEG C.  The Specification as open to inspection under Sect. 91 describes also the precipitation of chlorinated rubber from solutions by hot water, and stabilization of chlorinated rubber by treatment with alkalies, generally.  This subject-matter does not appear in the Specification as accepted.

Abstract: 576,705. Locking nuts. CRAWLEY, C. R. June 17, 1944, No. 11564. [Class 89 (i)] A self-locking nut 1, Fig. 1 is counterbored at 2 to receive a small circular nut 3 with its underside inclined at a substantial angle to the bottom of the counterbore. The nut 3 is retained in the nut 1 by a spring ring 4 or by other means such as by turning over the lip of the nut 1. The unturned end of the ring 4 engages a step or projection on the nut 3 to limit rotation and hold the parts in correct position for screwing on to a bolt.

Title: Improvements in or relating to erection systems for gyroscopes
Inventor: SCHNEIDER FREDERICK EDWARD WIL
IPC: G01C19/38
Filed: 1956-04-18
Abstract: 798,336. Gyroscopic apparatus. ENGEL & GIBBS, Ltd. Dec. 5, 1956 [April 18, 1956], No. 11851/56. Class 97(3) [Also in Group XXXVII] In a gyroscopic erection system having a control device responsive to the position of the gyroscope, an electric erection motor and a normal erecting circuit connecting the motor to a low voltage source, a fast erection circuit is provided to connect the motor to a high voltage source through the control device, with a normally open switch for completing the fast erection circuit and a holding relay which keeps the circuit closed irrespective of the operation of the switch until the circuit is broken by the control device. As shown in Fig. 1, the motor 10 of a gyro-vertical has a stator, winding 11. Torque motors 12, 13 have windings 14, 15 connected to mercury switches 16, 17. The roll switch 16 (see also Fig. 2) has pointed electrodes 19, 20 passing through a glass envelope 18 and connected by wire 21, 22 to the ends of winding 14, a central electrode 23 connected to a 26 volts supply 25, and a long electrode 26 connected to a 115 volts supply 28. The pitch switch 17 is similar and is connected to the ends of winding 15. The centre taps of the windings are connected to an earth point E. Connections are made through contact strips 32, 33 on the gimbal axes. The system described operates with D.C. but may be modified for single-phase or three-phase operation. A modified switch (Fig. 3) has, in addition to electrodes 19, 20, electrodes 35, 36 which project less into the envelope and are connected to the fast erection circuit, so that this circuit is broken before the normal erection circuit. As shown in Fig. 4, the high voltage supply 28 is connected to the electrode 26 of switch 16 through switches 40, 41. Switch 40 is closed when the pilot presses a button for fast erection. Current flows to electrode 26 through a relay coil 42 and normally closed switch 41. Relay 42 operates holding contacts 44 and contacts 45 which operate an audible or visual warning device 46. The fast erection circuit may be broken in emergency by pressing a button to open switch 41. As the gyroscope nears erection the circuit through electrodes 26, 19 or 26 20 is broken, whereupon relay 42 is de-energized, and the normal erection circuit through electrode 23 takes over. When the circuits are A.C. operated, a bridge rectifier circuit supplies D.C. to operate the relay. In the modified circuit of Fig. 6. a voltage operated relay has coils 48, 49 each connected across on half of the winding 14. According to the tilt of switch 16, one or the other of the coils will be energized when switch 40 is operated. A warning indicator and emergency switch may also be included in this circuit. To avoid flutter, a delay switch may hold the fast erection circuit closed for a short additional time. The roll and pitch switches may be replaced by pairs of switches mounted at an adjustable angle to each other. Specification 793,173 [Group XXXVII] is referred to.

The co-condensate thus prepared is diluted with conventional solvents, e.g. aromatic hydrocarbons, alcohols, ketones or esters, to the desired viscosity and finally mixed with a heat-resistant pigment and, if desired, with hardeners, e.g. Pb, Co or Zn naphthenate or with titanic acid esters. Examples are given of the above preparation of the lacquer resins.
