Title: Improvements in or relating to capsule banding machines
IPC: A61J3/07
Filed: 1958-10-10
Abstract: A capsule banding machine comprises a capsule receiving device, beneath which is a horizontal endless capsule conveyer having a plurality of open-topped capsule carrying cups, substantially equally spaced in the direction of its movement, means for driving the conveyer, timed means for causing the receiving device to deposit a capsule in each cup as it passes below the device, and a rotary member furnished on its periphery with a capsule-sealing liquid supported above the conveyer in a position to contact the capsules in succession as they pass thereunder and to coat a band of said liquid on each of them, and retarding means adjacent the conveyer for contacting deposited capsules and causing them to rotate about their axes.  Capsules are placed in a hopper and feed device 52 (Fig. 1) which contains a vertically reciprocated and pivoting plate which supplies them in single file to a delivery tube 53 connected to the repeating, single-capsule delivery unit 54.  The unit 54 incorporates a reciprocated check rod and a pair of jaws which, when closed, provide a cavity for receiving a capsule, and <PICT:0902529/III/1> <PICT:0902529/III/2> <PICT:0902529/III/3> when opened, deposit the capsule in a cup on a conveyer 55.  The said cavity may be so shaped that if the larger end of a capsule is presented to it, the capsule only partially enters the cavity, and, when released, its protruding end strikes a rod which reverses its orientation.  The conveyer 55 comprises a chain 115 carrying blocks 116 (Fig. 18) on which blocks 114 are mounted for vertical movement, the blocks 114 being urged away from the blocks 115 by springs (not shown) and being formed with cups for receiving the capsules C.  The conveyer carries the capsules beneath the banding means 57, which, as shown in Fig. 18, comprises a reservoir 133 for liquid L, in which a wheel 135, is rotated in such a direction that its protruding lower portion moves in the opposite direction to the conveyor.  The edge of the wheel 135 is serrated, and engages the capsules, coating them with liquid and causing them to rotate.  Electropneumatic means are provided for removing the capsules from the wheel 135 when the machine is stopped, by means of a stirrup 151 acting on pivoted plates 140 which depress the blocks 114.  After banding, the capsules pass to hardening means 60, where air, supplied from a pipe 155 is blown upon them, while they are caused to rotate by stationary friction strips engaging their upper surfaces adjacent the ends.  Finally, the capsules are removed from the conveyer 55 by a transfer wheel 61 having a plurality of suction cups 165, and deposited on a conveyer 62.  In a modified capsule banding unit, Fig. 37, the edge of the banding wheel 240 is provided with groups of serrations, and the banding fluid is retained in a reservoir 243, the reservoir bottom and sides providing wiping surfaces for the wheel 240.

Title: Device for reading diagrams recorded in several tracks on diagram charts
Inventor: KELCH H
IPC: G07C5/00
Filed: 1970-07-03
Abstract: 1320410 Chart readers KIENZLE APPARATE GmbH 3 July 1970 [28 July 1969] 32389/70 Heading G4H [Also in Division F2] In a photo-electric reader of a paper disc recording chart bearing several concentric recording tracks, the chart is inserted into the reader and a rotating boss on the end of a shaft moves axially to clamp the disc which rotates therewith to be scanned by a photo-electric device. A photo-electric clock pulse generator is geared to the rotating boss which is driven by a continuously rotating motor which also drives the photo-electric device radially by one track after each revolution of the disc. Fig. 2 shows the electric circuit of the reader. Clock pulses 2 are counted in a binary counter 10 to inform a control 11 of each revolution of a disc, whereupon the photo-electric device is moved by one track. Photoelectric pulses L read from the disc and whose length say is the time of operation of a machine, gate clock pulses to a counter 9 for the duration of the pulses. The counter is then read out to a printer 12 at the end of each revolution. The disc also contains in other tracks marks which are themselves to be counted and the photo-electric pulses generated thereby are fed to counter 9 by means not shown. The disc may also contain in one track information as to how data in another track is to be interpreted, for example a scalefactor. Fig. 3 shows the mechanical details of the reader. A continuously rotating motor 19 drives shaft 28 bearing a clock pulse apertured disc 31 and a worm gear 30 driving a wide helical gear 33 on the end of a shaft 36. A disc record is inserted into the flap 53 and comes to rest upon a lug 62. The presence of the disc operates a photo-electric switch which causes an electromagnet 44 to clamp a worm-wheel 42 causing the worm of shaft 36 to move axially permitting the boss 34 to pick-up the disc and clamp it by pins 35 against a freely rotatable rubber disc pad 50. A micro-switch 48 operated by the remote end of the shaft 36 signals the clamping of the disc and initiates scanning of the outside track by a pair of photo-cells in a housing 72. After one revolution the housing is moved in slide 76 by one track width by worm-operated cam 87. A magnetic brake 92 and clutch 25 transmit the motion from the continuously rotating pulley wheel 24 to the cam worm 84. The track position of the photo-electric device is signalled by a set of switches 81 operated by cams 87, 88.

Title: A new or improved process for the manufacture of pectin products
IPC: C08B37/06
Filed: 1925-12-28
Abstract: 269,952. Nanji, D. R., and Paton, F. J. Dec. 28, 1295. Gums, carbohydrate.-Pectin extracts suitable for jam, jellies, confectionery, &c., are obtained by treating pectinous plant materials with very dilute solutions of salts, which by effecting ionic exchange with the insoluble pectin compounds, render them soluble, so that they may be substantially completely extracted. There is simultaneous formation of soluble pectinous salts, whose solubility depends on the kation of the added salt; and of an insoluble or soluble salt of calcium, magnesium or iron with which metals the pectin is largely combined in the raw material. Salts of ammonium, or of the alkali metals especially those capable of forming insoluble compounds with the alkali earth metals, such as ammonium sulphate, phosphate, citrate, tartrate &c., are preferred. If the raw materials are excessively acid, the acidity may be reduced by electrodialysis; while the pectin extract may be acidified by addition of the requisite quantity of acid for jellification or by the removal by electrodialysis of the kation of added salt, added in excess of the requirements of the main process. The jellifying power of the extract may be augmented by the small addition of calcium salts. In an example one ton of dried apple pomace is treated with 1000 gallons of a 0.1-0.5 per cent solution of ammonium tartrate at 120‹ C., under pressure. The extract is pressed out and the residue again extracted and so on. The extracts are used then to treat fresh pomace, and may be treated by absorbents, filtered or centrifuged. The concentrated extracts jellify when acidified and heated with sugar, or may be preserved by addition of sugar or other materials such as toluene, or dried to solid form by evaporation. The process may be applied to making jam from dried fruits such as dried prunes, the prunes being extracted with ammonium tartrate &c. solution, and the digestion mixture mixed with sugar and acid, and if necessary, additional pectin preparation.

Title: Improvements in and relating to apparatus for indicating the level or quantity of liquid in a tank
IPC: G01F23/76
Filed: 1933-11-27
Abstract: 429,348. Indicating liquid levels. HILL, H. W., 101, Laitwood Road, Balham, GEORGE, T. A., 24, Rectory Grove, Clapham, and PARKIN, T. D., The Green, Southgate, all in London. Nov. 27, 1933, No. 33064. [Class 123 (i)] [See also Group XIX] A float 13 is mounted on a shaft or rod 7, which is preferably flexible, in such a manner that when the float is in contact with the liquid it is locked to the shaft by the effect of its tilting action on a quick-pitch screw. A fixed guide tube 1 is slotted at 4 for the passage of a part connecting a sleeve 6 with the cable 7. A double-armed lever 9 is pivoted at 8 to the sleeve 6, and carries at one end a set-screw 10 and at the other end a quick-pitch screw 11. The screw 11 is secured to a lever arm 12 and float 13. When the cable 7 is operated from a distance to lower the float 13, the latter becomes horizontal on reaching the liquid surface, and the screw 11 is rotated so that it bears against the guide 1 while the screw 10 also bears against the guide and the cable is locked against further movement. In a modification, a second float and lever may be provided in a diametrically opposite position to prevent freeing of the cable when the tank is tilted. Downward movement of the float is assisted by a weight 14. The outer end of the cable 7 is attached to a drum 18, Fig. 5, having a peripheral groove 19 which engages with threads 22 on the casing so that the drum moves axially and the cable passes tangentially into its groove 19. The spindle 20 carries a toothed wheel 23 which actuates a pointer 25 through gearing 24. The spindle 20 also carries a plate 201 and coiled spring 29 which tends to unwind the cable 7 and so lower the float. To enable the drum 18 and float to be locked in any position, the spindle 20 is made hollow to receive a, rod 30 with handle 31. The rod 30 carries a projecting pin 33 and pawl 34 cooperating with a ratchet wheel 35 on the spindle 20. This wheel is prevented from rotating in one direction by a pawl 36. If the handle 31 is pulled outward and rotated, the spring 29 can be wound up. To ascertain the level, the handle 31 is pressed inward to allow the spring 29 to unwind, and lower the float. The parts 30-36 may be omitted, in which case the float must be held in the raised position by hand by means of a knob on the spindle 20.

Abstract: 924,833. Etching. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 3, 1961 [Sept. 28, 1960], No. 33310/60. Class 100 (2). A method of etching one face only of polytetrafluorethylene or other strip or sheet material comprises unwinding the material from a roll at a point clear of the etchant with part only of the circumference of the roll in contact with the etchant and with the side edges of the sheet or strip protectively covered throughout the unwinding operation. The etchant is 1-2% metallic sodium dispersed in anhydrous liquid ammonia at - 40‹ C. The edges are protected by covering with a composition comprising a synthetic rubber resin adhesive in a petroleum solvent. The material is cleaned in acetone before being wound into the roll. The etching bath 3 is covered and is supplied through a pipe 3a with nitrogen, since the etchant reacts with air. The roll 1 is tightly wound on a roller 2, and after withdrawal of the strip the protective composition remains on the roller ends. The etched strip is passed through two water baths 13, 14 and a bath 13a of nitric acid to remove deposits of carbon formed during etching, and is then passed between drying pads 16 to a take-up roller 15.
