Inventor: NAMALIS PATRICK
IPC: C07H19/052
Filed: 1949-08-19
Abstract: The invention comprises acetylated benziminazole-glycosides of the formula <FORM:0682960/IV (b)/1> where R is hydrogen or methyl, R1 is methyl and R2 is a residue of the formula <FORM:0682960/IV (b)/2> in which either n is 2 and R3 is -CH2OOCCH3 or -CHOOCCH3-CH2OOCCH3 or n is 3 and R3 is hydrogen or -CH2OOCCH3.  These are made by forming R : R1-substituted benziminazoles by the process of Specification 677,540 and treating the silver derivatives of the products with acetochloro, acetobromo or acetiodo derivatives of sugars in a dry inert solvent, e.g. benzene, toluene or xylene. The glycosides are characterised as picrates and can be purified by chromatography.  The acetyl groups may then be removed. Examples show the preparation of 5-methyl-benziminazole, 4 : 5-dimethylbenziminazole, 5 : 6-dimethylbenziminazole, 5 : 6 - dimethylbenziminazole - 1 - a  - triacetyl - l - arabopyranoside, 5 : 6 - dimethylbenziminazole-1-b -tetracetyl-d-glucopyranoside, 5 : 6 - dimethylbenziminazole - 1 - b - triacetyl - d - ribopyranoside, 5 - methylbenziminazole - 1 - a  - triacetyl-l-arabopyranoside and 4 : 5-dimethylbenziminazole-1-b -tetracetyl-d-glucopyranoside.

Title: Means for obtaining selective reception of radio and like signals
IPC: H03H2/00
Filed: 1929-07-15
Abstract: 315,663. Ardenne, M. von. July 14, 1928, [Convention date]. Thermionic amplifiers.-To increase the selectivity of a tuned input circuit (such as a frame aerial) connected to an aperiodic amplifier, the damping effect of the apparent grid resistance of the first valve (due to reflex action from its plate circuit) is minimized by inserting a large series resistance Rg, Fig. 2, or a small series condenser C, Fig. 3, between the input circuit and the grid. By this means the apparent resistance R1 which is represented in dotted lines on Figs. 2 and 3 carries only a small fraction of the aerial current and consequently has a minimum damping effect. The cascade of resistance-coupled amplifiers is designed to have low amplification for disturbing low-frequency currents, such as may be picked up by the aerial or fed to the valves with the supply current. When a condenser C is employed its capacity is of the same order as the grid capacity of the first valve, and grid bias is applied through a grid leak R2.

Title: Improvements in or relating to ring-and-roller moulding or calendering presses
IPC: B29C43/22
Filed: 1943-12-29
Abstract: 574,073. Moulding brake linings, clutch facings, &c., in ring-and-roller machines. SNOW, H. Dec. 29, 1943, No. 21817. Convention date, Nov.' 21, 1942. [Class 87 (ii)] In order to vary the depth of the compression channel 41, the roller 23 is vertically adjustable on the hub 16 on which rotates the ring 27. The roller is rotatably mounted on an axle 22 located in one of six bores 21 in the hub, the six bores being at different distances from the centre of the hub. To vary the position of the roller from that shown, the roller and ring are removed from the hub, and the axle 22 is removed from its bore 21 and placed in another bore. The hub is then detached from the frame 10 by removing six bolts 19, and rotated to bring the axle 22 vertically below the hub centre. The bolts 19, roller 23 and ring 27 are then replaced. In a modification, the axle 22 may be on either side of the hub centre. To vary the width of the compression channel, the Range 52 forming the outer wall thereof'is formed of a separate ring laterally adjustable by means of bolts 53 and staggered holes 54; when the width is thus adjusted, a fresh roller 23 of corresponding thickness is fitted on the machine. The ring carries a gear 31 and is driven by an electric motor 38. The roller is driven by frictional contact with the material being moulded. The material is fed into the compression channel by a vibrating hopper 43. The moulded product is stripped from the ring by a resilient blade 44 and passes out through a shoot 47. Wire mesh or other fabric backing may be fed into the machine with the (asbestos plus organic binder) material, to be incorporated with the latter.

Figs. 1, 3 show the application to a flight conveyer 13 travelling through a conduit 12 and comprising rubber or like discs 20 secured to an endless chain built-up of links interconnected by pins 17, the conduit being apertured at at 23 to allow material to be fed into a hopper 24. Material adhering to the discs 20 is knocked off by a hammer 37 extending through an aperture 22 in the conduit, the hammer being mounted on a plate 35. This plate is given an oscillatory motion by a flywheel 49 eccentrically mounted on a shaft 41 supported in bearing blocks 38 on the plate, the shaft being rotated by an electric motor 47 through a belt 44 engaging a pulley 43 secured to the shaft 41. The amplitude of the oscillations of the hammer is controlled by adjusting the position of the counterweight 53 which may be secured by a screw 54 in any one of a number of holes 52 in a disc 51 secured to the shaft 41. In a modification, Figs. 5, 6, a semi-cylindrical member 61 of resilient material is secured opposite the aperture 22 in the conduit and this is contacted by the hammer 37 so as to force its centre portion into contact with the flights 20. In a further modification, the flywheel 49 is replaced by three members eccentrically mounted on the shaft 41, these members being adjustably mounted on the shaft relatively to one another whereby the amplitude of the oscillations of the plate 35 may be adjusted. The hammer 37 is preferably made of elastic material such as rubber or synthetic rubber or provided with a coating thereof.

Abstract: 922,740. Refrigerating systems. CARRIER ENGINEERING CO. Ltd. June 13, 1961 [June 22, 1960], No. 21921/60. Class 29. In a continuous cycle absorption refrigerating system comprising a steam-heated generator 6, a condenser 7, an evaporator 4 and an absorber 3, and using water as the refrigerant and salt solutions such as lithium bromide as the absorbent, a solution strong in absorbing power is pumped from the generator 6 through a heat-exchanger 12 to the absorber 3 by a first pump 10, and a solution weak in absorbing power is pumped from the absorber 3 through the heat-exchanger 12 by a second pump 16 to the generator 6 for re-concentration. For partial loads, the steam consumption is regulated by varying the speed of the common pump motor 20 to regulate the rate of delivery of solutions; or alternatively, if the pump speeds are kept constant, a by-pass valve 21 is interposed between the input of strong solution to and the output of weak solution from the heat-exchanger 12. An anti-syphon loop 22 and a vent 23 is provided, which prevents the solution in the generator from being syphoned back into the absorber when the apparatus is shut down.

Title: Improved treatment process
Inventor: SEALE ALLEN GORDON
IPC: H05B6/32
Filed: 1968-05-09
Abstract: 1,271,493. Induction furnaces. STANELCOTHEKMATEON Ltd. 8 May, 1969 [9 May, 1968], No. 21945/68. Heading H5H. A molten charge is supported above the pouring aperture in the base of a crucible by electromagnetically induced forces acting on the charge. When heating is completed, reduction of the levitating magnetic field allows the charge to flow through the aperture. As shown the crucible 1 comprises a diabolo-shaped array of tubes extending between headers 2, 3 split at 5, 6 respectively. Water flows through the tubes from one header to the other. The individual tubes are alternately staggered radially. A helical induction heating and levitating coil 7 surrounds the upper part of the crucible and extends just below the pouring aperture 4 so that currents induced in the crucible and charge produce a levitating force on the charge. The above arrangement of induction coil and crucible may be disposed beneath a pouring aperture in a refractory oxide or graphite crucible which is surrounded by an induction heating coil. In this embodiment, the arrangement merely acts as a valve for the pouring aperture of the crucible. In Fig. 2, not shown, the crucible is hemispherical and constructed from two identical arrays of tubes, each supplied separately with coolant. The two arrays may be separated about a vertical plane. Thus initially in order to retain granular charge the two arrays are held together to prevent escape of the charge, but as the charge melts they may be separated slightly so that when the levitating field of the surrounding heating coil is reduced, the molten charge will be expelled through the crucible bottom. If the charge is initially granular, the aperture of the crucible may be closed by a liquid cooled plug until the charge melts.
