Abstract: 711,580. Abrading sheet material. BRITISH UNITED SHOE MACHINERY CO., Ltd., and GIBSON, G.W. May 26, 1953 [May 28, 1952], No. 13477/52. Class 60 A machine for roughing the margin of a piece of flexible sheet material such as is used for the linings and uppers of shoes comprises a rotary disc 12 having an abrasive face, an edge gauge 74 and a gravity-actuated presser foot 42 arranged to press the margin of the workpiece against the said abrasive face. The disc 12 is' secured to a rigid head 16 at the upper end of a shaft 6 which is mounted vertically in a frame 2 and rotated by a motor through a belt-and-pulley drive 22 including jockey pulleys 24; a cushioning disc 14 is positioned between the disc 12 and head 16. The presser foot 42 is carried at the end of a lever 36 pivoted on uprights 32 between horizontal screws'34 which can be adjusted to position the lever as desired transversely of the machine. A balance weight 44 is slidable on the lever for partially counterbalancing the weight of the presser foot. The downward movement of the, presser foot is limited by contact of the forward end 52 of the lever with an adjustable screw 50 in the frame 2. To permit adjustment of the angle at which the cylindrical underface of the presser foot is set relatively to the abrasive disc, the presser foot is bolted to a bracket 58 having studs 60, 62 sliding in an arcuate slot in the end 52 of the lever 36; the bracket is urged upwardly by a spring engaging the lower stud 62, and a screw 66 adjustable in the lever 36 engages the stud 60 to vary the inclination of the foot. Positioned over the abrasive disc 12 is a guard 78 supporting the workpiece and having a slot 86 through which the margin of the latter is forced by the presser foot into contact with the abrasive disc; the guard is secured by a stud 80 and thumb nut 82 whereby it may be swung away from the disc to give access to the latter. The edge gauge 74 is bolted to the frame 2 and has a vertical guiding face 76 extending from above the presser foot to below the abrasive disc. A shield 77 co-operates with the guard 78 to enclose the abrasive disc. A table 48 on which the workpieces are stacked is mounted above the lever 36. In operation, the lever 36 and presser foot 42 are adjusted as desired and the workpiece while supported on the guard 78 is fed by the operator under the presser foot with its edge engaging the edge gauge 74. The direction of rotation of the abrasive disc and positions of the presser foot, edge gauge and slot 86 are such as to assist the forward feed of the workpiece and keep the edge of the latter in contact with the edge gauge. Specification 454,431 is referred to.

Title: Improvements in process for obtaining clear extracts from semi-liquid mixtures
IPC: A23G1/56
Filed: 1941-10-21
Abstract: 552,896. Food extracts; beverages. MORGANTHALER, M. R., and INREDECO, Inc. Oct. 21, 1941, No. 13518. [Classes 14 (ii), 49 and 129] Clear aqueous extracts of vegetables, fruit, cocoa, meat, raw sugar, vitamins, spices &c. are obtained by converting the material into a pasty mass with gelatinized starch, freezing the mixture, thawing it, and mechanically separating the liquid, as by a centrifuge, sufficient starch being used to retain substantially all the solid particles during separation. The extracts which contain all or most of the mineral salts, vitamins, and aromatic and flavouring substances of the original material may be used as beverages or in soups. The residue consisting of edible material and starch may be treated with malt and added to other foodstuffs. Materials, such as cocoa, almonds and nuts, which swell when soaked in water are treated with an active malt solution before mixing with starch. Cereals, such as wheat, tapioca and sago, may be used instead of pure starch. Second and further extracts may be made from the residue, and added to the first extract if desired.

Patent GB-135855-A (GB)
IPC: B01D5/00
Abstract: 135,855. Fleming, R. March 25, 1918. [Convention date]. Direct gas-pressure apparatus, automatic; valves for pressure fluid, actuation of.-In condensing vapours, such as those produced in cracking oils by an injector 10 to which water under pressure is admitted by a pipe 11, the mixture is led by a pipe 13 to a tank 14, in which the gases separate. A pipe 18 conveys the liquid to an elevated tank 19, in which the oil and water separate, and which maintains the requisite back pressure. The gases emerge from the tank 14 through a passage 15 controlled by a valve 16 operated by an inverted cup 17. The rising gas fills the cup 17 and closes the valve 16, thus causing an accumulation of gas sufficient to force the liquid to the tank 19. The resulting fall in the liquid level allows the valve 16 to open for the discharge of gas. The valve 16 is thus alternately closed and opened. In another form of apparatus, a back-pressure is set up by a relief valve in the pipe 13, which is connected to a separating-tank of ordinary construction.

Filed: 1951-06-15
Abstract: 688,599. Electric indicating systems. STANDARD TELEPHONES & CABLES, Ltd. June 15, 1951, No. 14243/51. Class 40 (i) [Also in Groups XIX and XXXVI] An arrangement for indicating the variations of an electric or other physical quantity comprises electric trigger devices and counters controlled thereby, corresponding respectively to selected discrete values of the quantity, and means for periodically " inspecting " the value of the quantity, such means being adapted to cause operation of that counter corresponding to the highest selected value reached by the quantity at the moment of inspection. In the arrangement shown in Fig. 1, for indicating the variations in signal level at a station of an electric communication system, five cold cathode gas-filled trigger tubes 1-5, each corresponding to a selected signal level, control counting devices 6-10. The anode current of one or more variable gain amplifier stages such as 39 is passed to the moving coil 28 of a current-measuring device 20 whose pointer 21 is thereby located over a strip 22 and one of five strips 23-27 corresponding to tubes 1-5 respectively. When the portion 47 of a constantly rotating cam 36 closes a switch 12, H.T. voltage is applied to the tubes and, on the subsequent closure of switch 34, a capacitor 33 discharges through the primary of a transformer 35 thus causing sparks to pass from 22 to 21 and from 21 to 24 (as shown) so that a firing pulse is applied to the trigger electrode of tube 2 thus stepping on counter 7. Also, if the tubes are coupled by transformers 16-19 as shown, all the tubes to the right will also be fired, so that each counter will register the number of times a given signal level has been exceeded or not exceeded according to whether the needle 21 moves to the left or right for increasing signal levels. In a modified arrangement, operated by the amplifier gain control voltage applied through a reversing voltage-stabilized tetrode to a potential divider, successive adjustable tapping points are connected to the trigger electrodes of the tubes so that all those tubes to which a voltage of not less than the critical value is applied will be fired. The device 20 of Fig. 1 could be replaced e.g. by a pressure gauge, a water level indicator or a wattmeter.
