Title: Improvements in or relating to cold moulding compositions and their manufacture
IPC: C08G8/00
Filed: 1931-04-16
Abstract: An artificial resin composition suitable for cold moulding comprises a filler (e.g. abrasive grains), a potentially reactive phenolic resinoid in the A stage and a solvent liquid of non-aldehydic character which does not react to a material degree with the resinoid or its ingredients and has a boiling point above 100 DEG  C., or a mixture of such solvents which has a boiling point not less than 80 DEG  C.  Examples of solvents are hexalin, ethylene glycol, diethylene glycol, diethyl oxalate, diethyl phthalate, diethyl carbonate, triethanolamine, monoethyl ether of ethylene glycol, and butyl and amyl esters such as dibutyl phthalate.  Non-solvents such as castor oil, creosote oil, &c., may also be added and with some fillers, such as asbestos fibre, a volatile solvent may be included. In an example, a mixture suitable for grinding wheels and other abrasive implements comprises 350 grams of Aloxite grains, to which 6 c.c. of solvent is added, and 50 grams of a ground potentially reactive phenolic resinoid.  This is moulded in a hot or cold mould at a pressure of 1000-3000 lbs. per sq. in.  The moulded piece is discharged and baked for about 24 hours at from 80-160 DEG  C.

Abstract: 377,698. Gramophones. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and JACOBY, H. C. E., of General Electric Co., Witton, Birmingham. April 17, 1931, No. 11474. [Class 40 (ii).] In a gramophone motor of the squirrel-cage type the stator is mounted on a plate carrying a hub for the rotor spindle and hollowed out to accommodate a governor. The rotor consists of an internally-toothed laminated ring 26 held between rings 31 connected by bars 28 in the slots between the teeth, the whole being mounted on a disc 32 secured to the spindle 23 by a screw 37 engaging with a head 41 on the spindle. The stator laminations 1 are secured by screws 3 to a disc 10 carrying the hub 9 of the spindle 23. The disc 10 is concave in the middle with the exception of a boss 12 on which are mounted one bearing 25 of the governor and the regulating devices. The disc 10 is cut away as shown at 17 to accommodate the governor, which is of the ordinary type provided with a friction disc 62 engaging a brake block 89. The block 89 is carried on a lever 67 which can be adjusted by means of a cam on the end of an arm 77. The motion of the arm 77 is limited by a tongue 82 struck out of the arm 77 and engaging a slot 83 in a plate 88. The disc 10 is secured to the plate 88 by bolts 111 and rubber or like washers 113 to check vibration. The turn-table 47 is secured to the spindle 23 by a split ring 48. Within the hub 9 are bushings 52, 53 between which is a felt packing which receives lubricant from axial and transverse ducts 50, 51 in the spindle 23. Oil escaping at the bottom of the spindle is received in a well formed by an annular wall 33 on the disc 32. The spindle 57 of the governor is supported in bores in screws 63 in blocks, 24, 25, antithrust balls 65 being provided. The stator windings are so connected to a supply terminal 104 and terminals 93, 102, 103 that when the terminals 102, 103 are connected together and the terminal 93 is connected to the supply terminal 92 as shown the motor operates at 100-125 volts, whereas when the terminal 93 is connected to the terminal 102 it operates at 200-250 volts. Specification 374,908 is referred to.

Title: Improvements in or relating to wireless systems
IPC: H04B15/06
Filed: 1923-04-30
Abstract: 216,308. Kinman, T. H. April 30, 1923. Thermionic heterodyne receivers; undesired signals, eliminating or limiting. - In a heterodyne receiving system, the grid oscillatory circuit 4, 5 of the receiving valve o is tuned to the received waves and has small resistance and large ratio of capacity to inductance. Local oscillations are also applied to a separate coil 3 in the grid circuit, either by a separate source or by retro-action from the tuned plate circuit 6; and the tuned grid circuit 4, 5 offers low impedance to such oscillations so that a minimum of the local energy is impressed on the aerial circuit 1, 2. The tuned grid circuit may be directly connected in the aerial circuit, as shown, or it may be inductively coupled to the aerial coil 2. When a frame aerial is employed, the grid circuit 4, 5 may be connected in series between the aerial coil and the tuning condenser; or the frame aerial and its tuning condenser may themselves form the tuned grid circuit. The beats produced in the circuit 7 are preferably supersonic as in Specification 197,405, and are transferred to further amplifiers. Undesired wave-lengths received by the aerial produce only small potentials across the circuit 4. 5. A screen 10 prevents direct magnetic action of the circuit 6 on the aerial.

Title: Improvements in or relating to television and like transmitting systems
IPC: H04N5/06
Filed: 1937-04-23
Abstract: 496,119. Valve circuits. WHITE, E. L. C. April 23, 1937, No. 11607. [Class 40 (v)] An impulse generator is started and stopped by control impulses, the starting and stopping pulses originating from a single signal passing along a delay network. In Fig. 1, valve 1 of a multivibrator is started into operation when a pulse passing through delay network 11 reaches tapping 13 and is stopped when the same pulse reaches tapping 16, a square topped wave of the duration determined by tappings 13, 16 being generated and fed to output terminals 20, 21. Instead of a single delay network two delay networks coupled by an amplifier or buffer stage may be used. Alternatively separate delay networks for the starting and stopping pulses may be used as shown in Fig. 3. In this embodiment the discharge through hexode 30 is controlled by pulses applied to grids g<1> and g<3>. Normally grid g<1> is biassed to cut off. The control pulses must be of longer duration than the output pulses required. When the starting pulse is received grid g<1> allows current to pass and when the stopping pulse is received grid g<3> is biassed to cut-off so that current reaches output terminal 42 during the interval between the two pulses. If the control pulses are of saw tooth form the duration of the controlled pulse can be varied by altering the biasses on grids g<1> and g<3>. The invention is described for generating synchronizing pulses for television. Specifications 456,650 and 456,840 are referred to.

Patent GB-179191-A (GB)
Title: Improvements relating to the extraction of oils or fats from vegetable matters
IPC: C11B1/08
Filed: 1922-04-29
Abstract: The extraction of vegetable oils and fats by means of relatively low pressure is effected by humidifying the oleaginous matter before pressing so as to produce "cellular exudation" of the oil.  The desired humidity may be obtained by exposing the material to steam or to atomized water until its weight has increased by 10-40 per cent. The pressing may be effected while the material is hot or cold, and one-tenth of the pressure employed in processes in which humidification is not effected is sufficient.  In the case of coconut oil and pea-nut oil pressures of 5-10 kg. per square cm. are suitable.  Reference has been directed by the Comptroller to Specifications 18550/97, 28206/97, 7641/03, 15961/11, and 17529/11.

Abstract: 418,517. Crank shafts. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. April 26, 1933, No. 12166. [Class 80 (ii).] A crank shaft for an internal-combustion engine has a hollow crank pin or journal for the passage of liquid lubricant, and a guide therein which causes the liquid to follow a helical path as it flows longitudinally through the pin or journal. A cooling effect combined with separation of solid matter from the liquid is obtained. As shown, the guide may take the form of a helical plug D<2> notches D<6> being cut in the helix on the side nearest the axis of the shaft to prevent the formation of air-locks. The plug is held in position by grub-screws D4 threaded in continuations of the passages E<1> by which the liquid flows through the crankwebs. The journals C are lubricated by pipes C<2> having holes C<3> near the axis of the journal. In a modified journal, not shown, a helical plug similar to D<2> is provided, a single lubricating tube or boss being arranged to project so that its opening is close to the plug. The crankpins may also be provided with lubricating tubes or with a simple passage D<5> on the side nearest the crank axis. The liquid is pumped into the crank shaft through radial holes co-operating with an annular bearing and passes out through a relief valve.
