Title: Combined bagging and packing machine and method
Inventor: COCHRANE RICHARD HAMLIN
IPC: B65B9/093
Filed: 1961-01-18
Abstract: 982,394. Packaging - machines. INTERNATIONAL DEVELOPMENT CO. OF NATIONAL DISTILLERS & CHEMICAL CORPORATION S.A. Jan.18, 1961, No. 2110/61. Heading B8C. A machine for enclosing articles in a longitudinally doubled synthetic plastic sheet 8, Fig. 1, formed into an opentopped bag 16, by transverse seals 15, comprises a feed roll 9 and roller 10 for feeding the sheet downwardly, a spreader 18 for spreading the open side of the folded sheet, a heated cutter 79 for sealing and cutting the sheet transversely at 17, a guard means 103 for the cutter and a cutter control 106a to be operated by the guard means. The folded sheet 8 is fed from a supply roll 9 into a spreader sufficiently wide for insertion of an article thereinto and which trips feed control means 25 to operate a piston and cylinder 26 causing, by means of a rack 27 and gear-wheel 29 on the roller 10, to feed a length of bag predetermined by the trip rod 30 and bleeder control 33. The slack in the sheet is taken up by a tensioning means 50 associated with a brake drum 58 mounted on the roll 9 and connected by a cable 64 (not shown). At the end of the feed stroke a valve on the cutter/ piston cylinder 65 is automatically actuated to move a batten 80, mounted on the frame part 67<SP>1</SP>, against the cutter 79 it being timed to cut off and release the fitted bag length and seal the cut off edge of the next bag length. A gearing mechanism duplicated on either side of frame parts 86, 87 and comprising a tubular sleeve 84, rack bars 88, 88<SP>1</SP> (not shown) interconnected by gear-wheels 91 ensures even and uniform action of the cutter blade. To prevent accidental placing of an object between the cutter and the platen the cutter is provided with a guard 101, 102 mounted on projections 104 and the guard on retracting will operate the bleed valves 106a and reverse the movement of the platen 80 to inoperative position. In normal operation projections 104 are spaced slightly apart and are prevented from engaging the bleed valve by pins 107 mounted on a bar 106. These controls are contacted by said projections only when the cutting and sealing operations are completed to retract the cutter frames. The safety device may be hand operated by either of the bleed valves to return the cutter frames to complete the cutting operation. The machine may be selectively automatically or manually operated by actuating a vent control 100, in the latter case, for venting the feed cylinder-piston unit 26. A timer may be connected with the unit so that it will be operated at a certain time interval when a bag length has been fed through and the machine stopped. The weight of the article is such that it will cause the packaged end of the sheet to be pulled down past the spreader in that cycle in which another bag length is being drawn from the supply roll. The machine may be provided with a table or shelf 4. Reference has been directed by the Comptroller to Specification 855,472.

Patent GB-706983-A (GB)
Title: Improvements in or relating to the separation of crystallizable constituents from liquid mixtures
IPC: C07C7/14
Filed: 1951-01-30
Abstract: A component is crystallized from a liquid mixture in which it is present in a concentration of 60-90 per cent. by weight, preferably 80 per cent., by adding a diluent miscible with the mixture but which does not exercise a strong solvent action on the component, and then cooling the diluted mixture by adding a cooling liquid which is not, or only slightly, miscible with the diluted mixture.  The cooling may be augmented by using for cooling a readily vaporizable liquid such as liquid ammonia.  The resulting crystals are mechanically separated and may be washed with additional diluent during the separation. Part of the cooling liquid may be cooled after use without being freed from any dissolved constituents and recirculated to the process.  The diluted mixture is preferably continuously mixed in a finely dispersed state, e.g. by spraying, into a continuous stream of cooling liquid.  The initial liquid mixture may be a solution in a liquid of a crystallizable solid or mixture of solids, or a melt of crystallizable solids such as tar.  In examples: (1) a tar fraction concentrated to 80 per cent, naphthalene is diluted with a mixture of raw benzole and a pyridine base, cooled by adding water and the pasty mass of crystals separated; (2) a tar fraction concentrated to 80 per cent, carbazole is diluted with heavy benzole and the diluted mixture cooled by adding water; (3) a tar fraction concentrated to 80 per cent. alpha and beta methylnaphthalene is diluted with heavy benzole and mixed with liquid ammonia; the ammonia is allowed to evaporate and the resulting crystals separated.

Filed: 1922-01-26
Abstract: 198,007. Napier & Son, Ltd., D., and Wilkinson, G. S. Jan. 26, 1922. Fluid-pressure.-A hydraulic brake for vehicles comprises two cylinders adjoining at their open ends, a brake-applying piston in the one cylinder and a piston valve in the other, means for deliver. ing liquid between the two pistons and an outlet port for the liquid which is controlled by the piston valve. As shown, the valve cylinder C is preferably integral and coaxial with the brake cylinder A and a rotary pump G is adapted to deliver liquid from a reservoir F through the port H into the space between the brake-applying piston B and the valve piston D. Normally the liquid returns freely to the reservoir by ports C<2>, but the piston D can be operated by the pedal E to restrict these ports and so to establish the desired braking pressure in the cylinders for applying the brakes. By means of a projection D<2> on the piston D, the piston B may be directly actuated when the fluid-pressure is not available. The pump may be driven directly or indirectly from the propeller shaft of the vehicle. If it is desired that the fluid-pressure may be operative for either direction of movement of the vehicle, an arrangement of two pumps may be used with the necessary back-pressure valves to prevent return of the liquid through the pump which is inoperative at the time.

Title: Press of the worm screw type
IPC: B30B11/24
Filed: 1933-01-30
Abstract: 404,810. Separating liquids by extrusion. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT EXPLOITATIE VAN TEN BOSCH OCTROOIEN N.V., 25, Isaac Evertslaan, Arnhem, Holland. Jan. 30, 1933, No. 2840. Convention date, Jan. 30, 1932. [Class 46.] The pressure worms of worm screw presses are formed of separate convolutions or blades, the leading end of each blade, which engages the material initially, being set back relatively to the preceding blade nearer the inlet opening, thus producing a staggered formation of blade ends. The tail ends of the blades may be staggered in a similar manner so that each succeeding blade from the inlet towards the extrusion outlet is shortened at each end in comparison with the preceding blade. The leading ends of the blades are knife-edged for expressing fluid from the mass, while the tailends are shaped similarly, with one edge of the knives perpendicular to the axis of the worm. The pitch of the rear side of each blade may differ from that of the front or materialpressing side, also the pitch at the pressing face of one blade may be equal to the pitch of the rear face of the succeeding blade. The various blades may also have different pitches if desired. Figs. 1 and 3 show a worm in which a feeding or filling helix 1 of regular pitch of 50 mm. is used in conjunction with a pressure worm constructed in accordance with the invention. The leading end of the first pressing blade 2 is formed with a knife-edge 7 and has a pitch of 50 mm. on its rear face and 44 mm. on its pressing face. The second blade 3 is set back for a distance 12 and has a pitch of 44 mm. on its rear face and 38 mm. on its pressing face. The third blade 4 is again set back for a distance 13 and has a pitch of 38 mm. on its rear face and 32 mm. on its pressing face and so on throughout the whole series of blades. The rear ends of each blade are also set back as shown at 17, 18 etc. and the faces 17 of the knife edges at these points are perpendicular to the axis of the worm. The feeding helix 1 may have a larger pitch than either side of the first blade 2. Fig. 4 shows one method of regulating the size of the extrusion outlet by the adjustment of a slotted rotatable ring 27 over a disc 24 having an extrusion hole therethrough. In a modified construction a conical core is adjusted axially in the outlet by screw mechanism. Liquid or gas expressed from the material passes through a perforated casing surrounding the worm or into the hollow worm shaft.

Abstract: 1487501 Automatic control systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 23 Jan 1975 [24 Jan 1974] 2931/75 Heading H4K In a telecommunications exchange, the switching network and its terminal circuits are controlled by a plurality of stored program controlled mini-processors performing different functions and supervised by a central processor and a maintenance processor, the normally operative mini-processors being connected to the network via individual interface units, the arrangement is such that any defective miniprocessor is automatically replaced by a reserve mini-processor. As shown mini-processors MPF1-MPF4 perform line scanning and identification, path selection, dial signal (pulse or frequency) decoding, and junctor supervision respectively for a network R.C. of mini relay matrices. The mini-processors are supervised by a central processor CP having a store MC in which among other things class of service data is stored, and maintenance processor PM and memory MM which stores a copy of all the programs for MPF1-MPF4 and PC and the data in MC. If maintenance processor PM detects a faulty mini-processor it operates a corresponding changeover switch A1, A2, A3 or A4 to cut out that processor and cut in a reserve mini-processor MPS which it programs to take over the function. The front end processors monitor in real time the operation of the network and faults are reported to and recorded in the maintenance computer and on request logged and flagged on a line printer. The use of a time division network as an alternative to the relay network is mentioned.
