Patent GB-1305819-A (GB)
IPC: G10L25/78
Filed: 1970-07-13
Abstract: 1305819 Speech detector POST OFFICE 13 July 1970 [14 July 1969 13 March 1970] 33882/70 Heading H4R A voice signal detector receiving digitally encoded audio amplitude sampling values, for example for a PCM communications system, compares these values in absolute magnitude with a threshold level at comparator 10 and if the threshold is exceeded a counter 16 is enabled which after 250 Ásec. sets flip-flop 26 over line 28 to initiate transmission of the digitally encoded data. A higher-order stage of 16 produces pulses at 10 millisec. intervals during the duration of the speech burst, which pulses pass to counter 32 which after 15 pulses (150 millisec.) resets counter 16 via detector 34. When speech signals as detected at 10 cease, counter 20 (similar to 16 but operative only during "nospeech" periods) commences to count up, and when its count reaches that in 32 detector 36 produces a signal to reset 26. Thus an additional period equal to either the speech burst length or 150 millisec. (whichever is the shorter) is added to the detected speech burst period for control of transmission.

Title: An Improvement in or relating to the Production of Refractory Articles
Inventor: BURNETT ALAN
IPC: C04B33/32
Filed: 1966-07-28
Abstract: 1,178,967. Furnace linings. LOW MOOR ALLOY STEELWORKS Ltd. 26 July, 1967 [28 July, 1966], No. 33892/66. Heading F4B. A method of producing refractory articles, e.g. bricks, in which the raw materials together with fusible material are heated to fusion temperature in an electric arc furnace by first producing an arc between the electrodes of the furnace and broken pieces of electrode, or pieces of graphite or amorphous carbon within the furnace and then injecting an oxygen-rich mixture to support the combustion of the broken pieces of electrode as arcing continues. The melt is poured into preformed moulds which are subjected to controlled cooling. Alternatively the raw material may be placed directly into moulds for fusion and subsequent solidification. Sintering or glazing of refractory articles may be similarly effected. The method may also be employed to build up electric furnace bottoms in layers by partial fusion of the refractories, and to reline or repair furnace linings; new refractory material is spread where required and then fused in position in the oxygen-rich atmosphere.

Patent GB-649785-A (GB)
Title: Improvement in method of dry cleaning
IPC: D06F43/08
Filed: 1947-12-29
Abstract: Residual solvent is removed from goods <PICT:0649785/III/1> that have been dry-cleaned with the solvent by means of steam and agitation of the goods in a drying chamber wherein the pressure is maintained sufficiently low so as to maintain the temperature of the goods at less than about 120 DEG  F. the resulting mixture of steam and solvent vapour being removed therefrom.  The " drying " step may be applied to the single apparatus type of dry-cleaning process wherein the goods and solvent are tumbled in a drum rotated at a relatively low speed followed by draining of the solvent, the drained goods are centrifuged by rotating the drum at a speed sufficient to remove additional solvent therefrom but insufficient to cause undesired vibration of the drum, the remainder of the solvent being finally removed by contacting the goods in the drum with the sub-atmospheric pressure steam whilst maintaining the speed of rotation of the drum at a value sufficiently lower than the centrifuging speed to produce uniform distribution of the goods therein.  The resulting mixture of steam and solvent vapour is condensed to recover the solvent.  A drum load of 2 to 5 lbs. per cu. ft. of drum volume is preferred.  The speeds of rotation of the drum exemplified for the three steps of washing, centrifuging, and " drying " comprise 30, 500, and 50 r.p.m. The solvent content of the goods is preferably reduced by the centrifuging step to about 20 per cent by weight of the goods. The steam pressure during the " drying " step is preferably maintained between 0.5 to 2.0 lbs. per sq. inch absolute, resulting in a " drying " temperature of below 120 DEG  F., and particularly 100-110 DEG  F.  The drum rotation speed during " drying " is preferably such as to maintain the centrifugal force at the drum periphery between about 0.4-2.0 lbs. per lb. of goods.  The usual organic solvents including Stoddard solvent may be used for the cleaning step.  A suitable plant comprises a tumbler 10, consisting of a perforated liner rotatable drum 14 for the goods within an outer stationary casing 12, a direct-contact condenser 66 connected to the casing 12 through several spaced off-takes 64, a vacuum pump 88 connected by a pipe 90 to the top of the condenser, and a separator 80 connected to the bottom of the condenser by a pipe 74.  The tumbler is provided with a solvent inlet pipe 48, steam supply pipe 52, used solvent drain pipe 58, driving motor 28, valves being included in the various pipes so as to operate the sequences of the process.  Cooling water is supplied to the condenser through a pipe 70.  The system may be vented through a valved branch pipe 96 connected to the pipe 90. Many advantages of using vacuum steam " drying " over air drying, such as avoiding explosions, are given in the Specification. Specification 10260/12, [Class 91], is referred to.

Filed: 1935-12-13
Abstract: 464,939. Feeding sheets. RATCLIFF & SONS, Ltd., J., and BELL, W. Dec. 13 1935, No. 34567. [Class 100 (i)] A reciprocating means for feeding metal &c. sheets from a feed table 5, Fig. 1, to the grippers of the impression cylinder 21 of a printing-press is constructed with grippers 4, or other sheet holding devices, mounted in a reciprocating carriage 2 which takes the sheet and then is accelerated to the speed of the grippers by the time the sheet is transferred to the grippers. The carriage 2 moves in guides 7 which cause the sheet to be drawn first in a path in the same plane as the feed table and finally delivers the sheet in the plane of the receiving member. The carriage 2 is then decelerated to rest, and when the carriage is returned to feed a further sheet, the guides 7 in which rollers 6 on the carriage move are swung about a pivot 9 so as to raise the straight portion of the guides 7 to ensure that the grippers 4 do not interfere with the stationary registered sheet on the table 5. The guides 7 are moved by cam-and-lever mechanism 35, 34, 33, 31, 30, Fig. 4, acting in conjunction with a spring 22 which tends to raise the straight portions of the guides. The curved portions of the track raise the grippers away from the cylinder 21 after transfer of the sheets, and the carriage 2 is reciprocated by links 3<x> connected to arms 8 on the rock-shaft 9, the ends of the arms 8 moving over a path concentric to the path 7 and equidistant from the shaft 9. The shaft 9 is given a variable oscillating movement by means of a cam 19, Fig. 6, which oscillates a gear segment 13 adjustably connected to a shaft 14 and geared to a second segment 13 on the shaft 9. The cam 19 rotates the shaft 9 against the action of a spring 12. A stop 26 limits the return movement of the carriage 2, and the grippers 4 are registered with the cylinder 21 during the transfer of the sheet to this cylinder by means of a pair of spring-actuated conical pins on the carriage which engage depressions in the cylinder. The grippers 4 are kept open prior to receiving a sheet by means of a cam 23 on the cylinder engaging a bowl 24 on the gripper arm, which is acted upon by a spring 25 tending to close the grippers. The grippers 4 are opened to transfer the sheet by a cam 10<x> acting on a runner 25y on the gripper arm.
