Title: Method and apparatus for locaint a continuously moving web
IPC: B65H23/038
Filed: 1974-04-04
Abstract: 1463197 Guiding webs transversely B ZUMBACH [trading as ZUMBACH ELECTRONICAUTOMATIC] 4 April 1974 [19 April 1973] 15117/74 Heading B8R [Also in Divisions G1 and G3] The lateral position of a web bearing index markings is adjusted by scanning the markings using a photo-electric scanner the output of which is applied to a storage device. In a first embodiment, Fig. 1, the position of one edge of a marking 3 is scanned by a photocell 5 the output of which is in the form of a signal is applied to an amplifier 6 together with a reference from potentiometer 7 by means of which the transverse position of the web can be adjusted. An inverter 9 and change-over switch 8 makes provision for dark or light markings. The signal is fed via a rectifier 11 to a storage capacitor 12 provided with a slow discharge path 13. Between the markings the scanner signal is lower so that rectifier 11 is reverse biased. The voltage stored on capacitor 12 is applied to indicator 16 and to a control system comprising two threshold amplifiers 18, 19. The input to amplifier 19 is inverted so that relay 22 or 23 is energized if the stored signal rises above or falls below the threshold level. The relays operate a motor 24 to realign the webs. In a further arrangement (Fig. 3, not shown), the signal is fed via a series switch to the storage capacitor the switch being closed while a mark is being scanned by control signals derived from a photoelectrically scanned apertured disc mounted on the feed roller. The pulses from the disc are applied to a counter which closes the switch at instants corresponding to the scanning of a mark. This enables the system to operate with webs bearing dots of equal contrast to the alignment marks. The scanner utilizes a two path arrangement, light from a lamp being reflected from the web to one cell and passing through an adjustable aperture to the second cell. This reduces errors due to lamp intensity variations and enables adjustment to compensate for the shade of the web material to be readily effected.

Patent GB-402140-A (GB)
Title: Improvements in or relating to a process for making rubber thread
IPC: B29D99/00
Filed: 1933-05-26
Abstract: Rubber thread is made by forming a continuous length of coagulum from latices of different pH values, one at least of which is a coagulant for another.  Generally, acid latices coagulate alkaline latices, and alkaline latices coagulate latices having a pH value less than 4.5. The coagulable latex is preferably streamed into a bath of coagulating latex.  The action may be intensified by making the coagulable latex heat sensitive, and employing a heated coagulating latex.  The coagulable latex may be vulcanized, or may contain vulcanizing agents or the latices may have ingredients added which when brought together produce vulcanization.  According to an example, acid latex having a pH value of 4.5-7 prepared by the method described in Specification 288,268, [Class 70, Indiarubber &c.], is used as the coagulant for ammonia preserved latex.  Either may be streamed through a nozzle into the other.  The surface of the thread is preferably hardened by treatment with an acid, or alcohol, or a solution of a salt of a bi- or trivalent metal.  The acid latex of Specification 356,125 may also be used to coagulate less acid latices.

Title: Improvements in or relating to electric capacitor assemblies
Inventor: TURNER JEFFREY
IPC: H01G2/04
Filed: 1956-05-18
Abstract: 823,034. Capacitors. GENERAL ELECTRIC CO. Ltd. May 20, 1957 [May 18, 1956], No. 15606/56. Class 37. A capacitor assembly comprises wound electrodes completely embedded in a hollow cylindrical body of thermoplastic material which also constitutes the dielectric, the body embracing a core having a terminal-carrying member of non-conductive material attached to or integral with it. Figs. 1, 2 show a core 1 and a tag-plate 8 both moulded from high-density polyethylene, polystyrene or phenolic resin. Both members are formed with axial holes 2 through which a bolt may be passed. The core 1 is also provided with a cylindrical recess 3 in each end and slots 4 which correspond to the projections 9, 10 of the tag plate 8. The capacitor 6 is wound on the core 1 preferably from strips of aluminium foil and wider strips of stretched polystyrene; a connecting-strip 33 of copper foil being spot-welded or soldered to each electrode half-way along its length. The roll is then heated to between 100‹ and 110‹ C. to cause the dielectric to contract and embed the electrodes in a hollow cylindrical mass. A gap is left between the capacitor 6 and the tag-plate 8 to allow circulation of air and provides space for the leads 33 which are finally soldered to copper wires 34 embedded in the tag-plate. Series or parallel combinations may be formed by mounting a plurality of such capacitors, each with its tag-plate 8, co-linearly on one bolt. Tag plates having projections such as 9, 10 extending from both sides are then advantageous. The capacitor may alternatively be wound on a mandrel (such as that described in Specification 823,033) that is removed after heat treatment. In this case an integral core and tag-plate shown in Fig. 4 may be used. The outer end of the core is flanged at 28 and is cut into four sections which may be compressed inwards to allow passage into the capacitor 24. Shoulders 25 allow space for air circulation and for outlets of leads 32. A similar form of integral core, Fig. 3, not shown, is moulded from polystyrene and has a plain outer end burred over with a hot iron to retain the winding. A suitable pattern may be impressed into the outer end to locate a second tag-plate or a further capacitor.

[Class 28 (ii)] In a slicing- machine having in combination slicestacking mechanism including a rotatable slice conveyer ; a guide for attaching the slice thereto and a slice-thick ness - determining gauge, or fence, in close proximity to the knife and guide, the arrangement is such that slices being cut by the knife pass from the gauge to the conveyer between the knife and guide. The gauge may be used for initially positioning the article when the machine has a mechanical feed, or it may be used for controlling the manual feed when mechanical feed means are not provided. As shown, the gauge 15 is mounted for adjustment parallel to the slicing plane on rods 16, 17, and is formed integrally with the guide 28 which is bent back to connect with a comblike portion 29. The conveyer 23 may be operated by means as described in Specifications 353,442 to 353,446, suitably modified to drive it clockwise. The slice passes between the knife 13 and the guide 28 and is then engaged by the conveyer spikes 22 which bend it backwards to travel along the fingers 29 in a direction substantially opposite to that of the substance during the slicing stroke. The fingers 29 press the slice on to the spikes 22 and the discharge fly fingers 24 are formed to move the leading end of the slice away from the body of the conveyer. The fly swings in a direction opposite to that of the slicing stroke and deposits the slice on the table 27. The fingers 29 may be resilient, or they may have a spring mounting on the plate 15 so that they are urged towards the conveyer 23. The conveyer may oscillate instead of rotate. The rods 16, 17 or other guide means for the gauge 15, may be so arranged that the gauge is adjusted in a direction substantially parallel to the rear of the knife rim, the portion 28 being then arranged always to leave an adequate slice-passage space between itself and the knife.

Abstract: 1429773 Refining fats UNILEVER Ltd 4 April 1973 [6 April 1972] 15831/72 Heading C5C In the deodorizing of fats, the vapours from the deodorizer are cooled by injecting into them a spray of liquid so that the fatty matter in them is condensed, at least in part, and the condensate and injected liquid are then separated from the steam by centrifugal forces. As shown, a deodorizer 1 operates under high vacuum, and vapours are taken off to a separator 3, which removes entrained droplets. Steam from line 5 is injected into booster 4, and the vapours pass to 6, where liquid is injected from nozzles 7 to 11. The mixture of steam and condensed material enters a cyclone separator 12 tangentially. The steam outlet 15 extends downwards below the inlet to the cyclone, so that entrained material does not pass into it. The separated fatty matter and injected liquid collect in the bottom of the cyclone, and are drawn off at 14. Part of it may be recycled by pump 26 to nozzles 7-9 or it may go to fat trap 30, from which water may be recycled by pump 34 to nozzle 11 and the fatty matter taken off at 33. Fresh water may be introduced at 37. The cleaned steam is condensed in barometric condenser 17 and collected at 21. The liquid injected may be water, oil, glycerine, a fatty acid, a salt solution or the condensed fatty matter. Particularly suitable is an aqueous solution of an alkali, e.g. sodium carbonate. The oils treated in the examples are groundnut, coconut and sunflower oils.
