Title: Data transmission apparatus
Filed: 1971-04-07
Abstract: 1388543 Digital transmission; error correction DEFENCE SECRETARY OF STATE FOR 14 April 1972 [7 April 1971] 8928/71 Heading H4P In a duplex system in which errors are corrected by requested repetition, or alternatively new data is only sent on receipt of a "correct reception" signal, an error signal is additionally returned when an output register at the receiver has not been cleared so that data is repeated automatically until received correctly and passed to a utilization device. Data words are received into register 115. If correct this is passed through gates 119 to output register 117. If incorrect and until register 117 is cleared, detector 121 causes an error signal to be returned to the transmitter, which shuts gates 11 and causes re-transmission from register 9 operating in conjunction with serial store 13 having multi word capacity.
Patent GB-609796-A (GB)
Title: Improvements in the production of artificial filaments
IPC: D01F6/62
Filed: 1946-03-22
Abstract: Artificial filaments are obtained by extruding a water-free molten linear poly-(glycol-terephthalic acid) ester through an orifice having a diameter of 0.001 to 0.09 inches, and rapidly cooling the extruded filament, preferably by quenching in an inert liquid such as water.  The temperature of extrusion is preferably not more than 50 DEG  C. higher than the melting point of the polyester.  The ester may be made by heating one or more glycols of the series HO(CH2)nOH, where n is an integer greater than 1 but not greater than 10, with terephthalic acid or an ester-forming derivative thereof.  The glycol used may be ethylene, trimethylene, tetramethylene, hexamethylene, or decamethylene glycol.  An ester, acid halide, or ammonium or amine salt of terephthalic acid may be used instead of the free acid.  The filaments are preferably subjected to drawing when in the solid state, and preferably they are subjected to a heat setting treatment, at a temperature higher than that of the drawing operation, but preferably at least 30 DEG  C. below the melting point of the polymer, while they are held under tension. If a filament of high elongation is required, a restricted amount of shrinking may be allowed during the heat setting.  The heat treatment improves the resiliency of the filaments.  In an example, a highly polymerized polyethylene terephthalate (intrinsic viscosity 0.78 in 1 per cent solution in 60/40 phenol-tetra-chloroethane at 30 DEG  C.) is heated in the absence of oxygen at 285 DEG  C.  It is extruded in molten condition through a single hole orifice into water to form a filament of 0.02 inches in diameter.  The filament is drawn to five times its length in a water bath at 60 DEG  C.  The filament is subjected to a heat setting treatment in an oil bath at 150 DEG  C.  The filaments obtained may be used as artificial bristles for tooth-brushes, nail-brushes, shaving-brushes, clothes - brushes, scrubbing - brushes, yard brooms, or brushes for industrial purposes.  The filaments may be produced in tapered form, e.g. by varying the rate of draw-off. Such tapered filaments may be used as bristles for paint-brushes. The filaments may be used in making screens for sifting powders or filtering liquids, for excluding insects, or for lining shoes to be worn in the tropics.  The filaments may be formed into knitted or woven fabrics, including carpet backing material. They may be associated with filaments or fibres of cotton, wool, viscose, or cuprammonium regenerated cellulose.  They may be used in making fishing nets, ropes, sewing thread, musical instrument strings, artificial rattan for chair seats, sutures, artificial hair, and artificial gut.  Specifications 533,306, 533,307, 535,263, 536,379, 536,380, 578,238 and 603,840 are referred to.

Title: Process for plasticising polychloroprene
Inventor: SPARKS ANTHONY ARCHIBALD
IPC: C08C19/08
Filed: 1962-03-09
Abstract: Sulphur-modified polychloroprene (or copolymers thereof) is plasticized by reacting with tetraethylthiuram disulphide and a dialkyl ammonium dialkyl dithiocarbamate in which each alkyl group contains from 1 to 6 carbon atoms. Preferred are dimethyl ammonium dimethyldithiocarbamate and diethyl ammonium diethyl dithiocarbamate. The reaction preferably takes place in the latex produced by polymerisation and the addition of the plasticizing mixture serves to shortstop the polymerization.

Abstract: 801,512. Hydraulic machines. ELECTROHYDRAULICS, Ltd. March 8, 1956 [March 29, 1955],No. 9185/55. Class 69 (2). Solenoid-operated selector valves 1, 2 feed the combined output of electro-pumps 3, 4, either into the normal service line at C, downstream of non-return valves 9, 10, or into an emergency service line at D, downstream of non-return valves 11, 12. The valves 1, 2 are controlled by float switches 13, 14 on tanks 7, 8 feeding the pumps, which switches also control the pumps. Further operation of the system, after stoppage of the pumps and selection of the emergency supply line, is initiated by emergency switches which over-ride the float switches and allow fluid to be pumped to the emergency line. Relief valves 5, 6 prevent excessive pressure in the pump circuits. Surplus fluid from the supplies A, B is returned thereto, via lines 71, 81. Should a. burst occur in a line or component in either supply circuit between the tanks and non-return valves 9, 10, the affected circuit will lose fluid until the float switch stops the pump. The other pump will continue to run and the service will move at half speed.

Title: Process for the manufacture of cyclohexanone glyoxalic esters
IPC: C07C69/67
Filed: 1943-06-09
Abstract: Cyclohexanone glyoxalic esters are prepared by contacting cyclohexanone or an alkyl cyclohexanone with a diester, especially a dialkyl ester, of oxalic acid at a low temperature, generally about 0 DEG  C., in the presence of anhydrous sodium methoxide.  In an example, a mixture of cyclohexanone and diethyl oxalate is cooled to about 0 DEG  C., anhydrous sodium methoxide added over 2-3 hrs. so that the temperature does not rise above 5 DEG  C., and the mixture left for 12 hrs. at about 0 DEG  C. followed by 24 hrs. at room temperature.  Ice water followed by ice-cold hydrochloric acid is added to yield ethyl cyclohexanone glyoxalate.

Abstract: 1,210,232. Adaptive devices. P. C. DAVIES. 16 May, 1968 [27 Feb., 1967], No. 9309/67. Heading G4R. [Also in Division H3] In adapting apparatus, randomly-generated data for controlling a machine can be stored in a temporary store and transferred therefrom to a permanent store. In Fig. 2, a two-legged walking machine 5 is controlled by successive bit-groups on lines 16 coming from a random generator 1 (also stored temporarily at 2) or from a permanent diode store 3. Sensing contacts 23, 24 in the machine 5 feed manually-preset (e.g. by plugging) diode matrices 17, 18 which recognize " states " and " patterns " respectively. Recognition of a particular " state " causes a corresponding row of permanent store 3 to be examined to see if it contains data (indicated by one bit position) and if it does this data is applied to control the machine 5 on lines 16. If it does not and a " pattern " is recognized at 18 which " corresponds " to the " state " recognized at 17, then the temporarily stored bit-group at 2 is written into the row of permanent store 3 corresponding to the recognized " state " by burning through selected diodes (or fuses in series with them). The random generator 1 is then activated again. A simpler embodiment uses manual pushbutton switches to decide which bit-groups produced as above shall be stored permanently and which shall be applied to the machine.
