Title: Manufacture of Condensation Products of Gallocyanine Dyestuffs with Amines.
Inventor: IMRAY OLIVER
IPC: C09B19/00
Filed: 1917-06-19
Abstract: 116,754. Imray, O., (Soc. of Chemical Industry in Basle). June 19, 1917. Gallocyanines.-The condensation of gallocyanines with aromatic amines is effected in the presence of hydrogen peroxide or a compound or derivative thereof, such as a per-acid or salt thereof. Condensation products can thus be prepared from amines which contain, in addition to the free amino group, an acidylamino group or an iminazole group. Examples are given of the preparation of condensation products from the following parent materials :-gallocyanine and aniline, gallocyanine and o-anisidine, coelestine blue and p-aminoacetanilide, prune and 5-amino-2- methylbenziminazole; hydrogen peroxide, ammonium persulphate, and sodium perborate are employed according to the examples. The products may be reduced to their leuco compounds in the known manner; the products and their leuco compounds can be used for dyeing or printing. Specifications 15138/07, 20368/08, and 4963/09 are referred to.

Title: Improvements in and relating to apparatus for measuring and delivering predetermined volumes of liquid
IPC: B67D7/16
Filed: 1923-03-29
Abstract: 217,679. Hayes, S. M. March 29, 1923. No Patent granted (Sealing fee not paid). Fixed-chamber apparatus; varying quantity measured in ; valve systems for.-Relates to apparatus of the type in which the capacity of the measuring container is varied by adjusting the position of an internal overflow tray or tube and consists in opening and closing the supply and discharge valves by cams on spindles themselves connected to a rocking member operated by a cam on a rotating part of the measuring apparatus. The mushroom valves are held on their seatings by coiled springs and are arranged in casings 4, 5 at opposite sides of the measuring chamber 1. The valves are lifted off their seatings by cams engaging the ends of the valve spindles and carried on horizontal spindles 14. The opposing ends of the spindles are bridged by a yoke 15<a> rigidly secured to the spindles 14 and disposed about the overflow tube 3. The overflow tube is surrounded by a sleeve to which is secured a collar 17 formed on its upper surface with a cam surface 18 upon which opposite sides of the yoke member rest by means of ball-headed pins or lugs 19. The cam surface comprises two curved upwardly sloping portions which merge into each other at diametrically opposite short horizontal portions and is symmetrical on opposite sides of one diameter. The effect is that during a rotation of the sleeve, the yoke is rocked and for the first quarter of a revoultion one valve is opening and the other remains closed. For the second quarter of a revolution both valves remain closed, and for the third quarter the first valve is closed while the second opens, both valves remaining closed during the final quarter turn. Specification 218,371 is referred to.

Patent GB-548961-A (GB)
Title: Improvements in automatic record changing mechanisms for gramophones
IPC: G11B17/02
Filed: 1941-07-18
Abstract: 548,961. Automatic gramophones. INDUSTRIAKTIEBOLAGET LUXOR. July 18, 1941, No. 9103. Convention date, May 30, 1940. [Class 40 (ii)] Relates to gramophones in which resetting and record-changing mechanism is driven through a friction pinion 3 automatically engaged with and disengaged from the rim 5 of a turntable 2 or like disc driven by the motor. According to the invention, the pinion 3 is on a displaceable shaft 6 adapted to be influenced by two springs 14, 15 ; one spring, 15, is stronger than the other and normally overcomes the other and holds the pinion out of action ; and automatic means puts the spring 15 out of action for record changing. As shown, the spring 15 acts on a member 16 formed with a bent end 17 which normally engages the end of the shaft 6. At the end of the playing of a record, a device (not shown) controlled by the pick-up arm in known manner acts on the lefthand end of the member 16 and pushes this member from the position, Fig. 2, to the position Fig. 3, whereupon a spring 23 acting on a pin 33 on the member 16 rocks this member and brings a bayonet notch 22 into engagement with a pin 21, thereby locking the member 16 in that position. At the same time spring 14 presses pinion 3 into engagement with rim 5 of turntable 2. Drive is then transmitted through this pinion and through worm gearing 9, 10 and spur gearing 11, 12 to the shaft 27, one rotation of which is required to perform the record changing and associated operations in known manner. A disc 26 carrying a finger 24 is loosely mounted on the shaft 27 and is confined between two pins 29, 30. A spring 32 acting between pins 29 and 31 normally urges the disc 26 counterclockwise, causing the finger 24 to abut the pin 30 as in Fig. 2. Near the end of an operative rotation of the shaft 27, the finger 24 bears over the right-hand end of the member 16, and the deflection of the member 16 thus produced releases the notch 22 from the pin 21, allowing the spring 15 to urge the member 16 to the left. This movement is transmitted by the right-hand end 17 of the member 16 to the shaft 6 with the result that the friction pinion 3 is disengaged from the rim 5 of the turntable and the parts are restored to the position, Fig. 2, in readiness for the next operation after the fresh record has been played. The worm gearing 9, 10, is designed to produce a thrust along the shaft 6 of the friction pinion 3 towards the right to help spring 14 in pressing pinion 3 into engagement with rim 5 of turntable.

Abstract: 218,019. Burden, W. M., Burdon, M. M., and Burdons, Ltd. April 3, 1923. Liquid-fuel furnaces. - A furnace for forging, welding and other heating purposes and fired by oil fuel comprises a bridge 4 dividing the furnace into a lower-combustion chamber 2 at the rear of the furnace from the upper part of the working chamber 3, so that the flame travels along the bottom of the furnace, round the article to be heat-treated and back along the crown to a regenerative chamber 6 behind the combustion chamber, as shown. The burner 11 is fed from a fuel tank 13 and is connected with the air supply through a regenerative pipe 12. Openings 8 are provided in the side wall of the working chamber for the insertion of articles to be heated; the front portion 9 is also removable for this purpose. The furnace is substantially oblong in shape but with the sides converging towards the front. The top 10 of the furnace may be hinged and fitted with balance weights.

Title: Improvements in or relating to pull and push transmission rods
Inventor: SCRIVENER EDWARD WILLIAM ARTHU
IPC: B60T13/10
Filed: 1960-03-16
Abstract: 916,798. Vehicle brake-operating mechanisms. WAR DEPARTMENT, SECRETARY OF STATE. June 14, 1961 [March 16, 1960], No. 9257/60. Class 103 (1). [Also in Group XXIX] A transmission rod for operating a mechanism, such as a brake, comprises two parts 3, 4 coupled hydraulically whereby the actuation of one part relatively to the other causes pressure in the coupling to act on the other part, the pressure, when it reaches a predetermined value, then serving to apply additional thrust to the other part. The part 3 is formed with a cylindrical extension 5 which has a clearance 5a within a stationary housing 1 and receives a piston 16 on the part 4. The extension 5 also houses a container 6 for valves 9, 10, the space between the valves being connected by a passage 24 to a chamber 22. A seal 23 permits fluid from the clearance 5a which is connected by a chamber 19 to a reservoir 21, to pass in one direction to the chamber 22, and a seal 17 permits fluid to pass in one direction from the chamber 19 to a chamber 18. In operation, when the part 4 is pulled to the right, the piston 16 pressurizes fluid in chamber 18 and permits a spring 15 to close valve 9. The fluid in chamber 18 acts through a passage 13 on the valve 10 and, when the pressure of the fluid reaches the predetermined value, the valve 10 opens against a spring 11 to connect chamber 18 through passage 13, valve 10, the container 6 and a passage 24 with the chamber 22 so that the pressure therein also acts to move the part 3. When the part 4 is returned to the left, fluid to the left of piston 16 passes through a passage 25 to the chamber 19 and fluid in chamber 19 can pass the seal 17 to fill chamber 18. When the piston 16 reaches its extreme left-hand position, it opens the valve 9 so that fluid in chamber 22 can pass through passage 25, container 6, valve 9 and passage 25 to the chamber 19, the part 3 being returned to its initial position by, for example, a spring. If the part 4 is reciprocated without operating the valve 10, the chambers 18 and 22 are continuously replenished by fluid from chamber 19 to effect increased movement of the part 3. The arrangement may be applied to a push-rod.
