Title: Improvements in and relating to the recovery of wax from a mixture of wax and poultry and/or game feathers and the like
IPC: A22C21/04
Filed: 1937-01-16
Abstract: <PICT:0490742/III/1> <PICT:0490742/III/2> Mixtures of feathers and wax such as are obtained in certain poultry-plucking processes, are separated into their constituents by heating the mixture until the wax is molten, submitting the mixture to pressure so as to separate the wax from the feathers and substantially preventing the two constituents from re-uniting.  The pressure is preferably supplied by contacting rollers, of which at least one is covered with a yielding material such as the rubber-like substance Neoprene to prevent damage to the feathers.  The rollers are heated internally or by immersion in a bath of hot water.  In the first embodiment, Fig. 2, the heated mixture of wax and feathers is fed from a tray 22 on to rotating soft-covered rollers 3, 4, almost immersed in hot water at a level 23.  The wax separated floats on the surface of the water and flows away through an outlet 18.  The feathers sink to the bottom of the tank and are raked out through the opening 25 on to a tray 21.  In the second embodiment, Fig. 4, the heated mixture is fed from a tray 22 on to a moving flexible belt 28 which passes between a soft pressure roller 32 and a hard roller 30.  The wax liberated descends by gravity on to the hot water in a tank 34, whence it escapes by overflow 35, while the feathers are thrown off by a roller 31 into a container 36.

Title: Chlorinated ethylene polymers
IPC: C08F8/20
Filed: 1952-01-17
Abstract: Highly chlorinated polymers or copolymers of ethylene or mixtures with other polymers are obtained by chlorinating in chloroform at a temperature exceeding the boiling point of chloroform.  After a chlorine content of 20 per cent. is reached, the process may proceed at lower, e.g. room, temperatures.  The process may be performed by adding to the chloroform a chlorine-resistant solvent which gives the mixture a higher boiling point than chloroform, or by chlorinating under super-atmospheric pressure with or without another solvent. Carbon tetrachloride is the preferred additional solvent; trichloroethylene and chlorobenzene are also specified.  The chlorinating agent may comprise chlorine or N-chlorinated sulphonic or carboxylic acid amides.  The process may be effected in the presence of catalysts, e.g. iron chloride, aluminium chloride and iodine, irradiation, and acid-binding agents, e.g. sodium carbonate, bicarbonate or acetate.  The ethylene may be copolymerized with vinyl chloride, vinylidene chloride, styrene, butadiene and acrylic acid ester.  Other materials which may be mixed with the ethylene polymers include natural rubber and polymers and copolymers of butadiene, styrene, vinyl chloride and isobutylene.  The products, which may have chlorine contents of over 60 per cent., may be used to make films, fibres and varnishes.ALSO:Highly chlorinated mixtures of natural rubber and polymers or copolymers of ethylene are obtained by chlorinating in solution in chloroform at a temperature exceeding the boiling point of chloroform.  After a chlorine content of 20 per cent. is reached, the process may proceed at lower, e.g. room, temperatures.  The process may be performed by adding to the chloroform a chlorine-resistant solvent which gives the mixture a higher boiling point than chloroform, e.g. carbon tetrachloride, or by chlorinating under super-atmospheric pressure with or without another solvent.  In an example, equal parts of rubber and polyethylene are dissolved by heating in a mixture of 20 per cent. chloroform and 80 per cent. carbon tetrachloride and a stream of chlorine passed through at 70 per cent. until the product precipitated in boiling water showed a chlorine content of 69 per cent.

Title: Improvements in or relating to arrangements for delaying electric pulses
IPC: G01S13/18
Filed: 1944-01-31
Abstract: 592,575. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd. Jan. 31, 1944, No. 1816. Convention date, Jan. 30, 1943. [Class 40 (v)] A pulse variably delayed with respect to a synchronizing pulse and suitable as a range marker or for the control of a vernier time base in a radiolocation system of the type described in Specification 592,574, is produced by generating a train of pulses and applying them, together with the variably delayed synchronizing pulse, to a gate valve, the output pulse from which thus moves in steps as the timing of the delayed synchronizing pulse is varied. The radiolocation system of Fig. 1 comprises a pulse transmitter 10, aerial 12 and receiver 14, the received echo signals being displayed as vertical deflections on a main oscillograph 21 and a vernier oscillograph 22. A pulse 11a from the transmitter corresponding to the transmitted pulse 11, Fig. 2, controls the sweep generator 23 which produces the time base sweep A-B on the main oscillograph, and is also fed to a phase reversing amplifier 24. The phase-reversed pulse 11b controls a generator 26 of the type described in Specifications 582,146 and 592,580, producing a train of pulses 28 which are applied as calibration markers to the main oscillograph 21 and are also fed to control the generator 32 producing saw-tooth sweep voltages corresponding to the intervals between pulses 28, which are applied to the oscillograph 22 to produce the vernier sweep XY. The pulse 11b is also passed over the adjustable delay device 35, the distorted delayed pulse 11c being sliced in the limiting device 40 at levels 42, 43 to produce the pulse 11d which is applied to one grid of the gate valve 50, to the other grid of which are fed the pulses 28. Valve 50 produces an output pulse 28a which corresponds to the pulse 28 and occurs during the interval of pulse 11d, and which is applied to a multivibrator 62 to produce the extended pulse 63, the duration of which is made equal to the interval between pulses 28. Pulse 63 is limited at 64 and fed to the grid of oscillograph 22 to remove the blackout and render visible the sweep X-Y corresponding to the selected interval 70 of the main sweep A-B. Pulse 63 is also fed through an attenuator 68 to the grid of oscillograph 21 to increase the brilliance of the selected interval 70. The reference pulse 28a is also applied to a calibration pulse generator 74 producing calibration pulses 75 for the vernier sweep X-Y. The distance of an obstacle giving rise to an echo signal 65 is determined by observing the time intervals t1 and t2 on the main and vernier oscillographs indicated by the marker and calibration pulses.
