Title: Web handling apparatus
IPC: G03D3/13
Filed: 1964-03-23
Abstract: 994,018. Feeding webs. EASTMAN KODAK CO. March 23, 1964 [March 22, 1963], No. 12117/64. Heading B6B. [Also in Division G2] A web 10, Fig. 1, is fed through a series of photographic processing tanks 12-14 (developing, fixing, washing) and a dryer 15 to a takeup reel 16 driven by a motor 17, which may also drive some of guide rollers 18. The web is threaded through the apparatus at normal working speed by means of a towbar 20, to which the leading end of the web is attached, and which follows the processing path on a chain-drive 22 driven by a motor 19. After the towbar 20, Figs. 1 and 2, has drawn the web round a take-up spool core 24 provided with an activated glue, it strikes a trip arm 32, causing a lever 30 to force the web against the core. The bar then actuates a cutter mechanism 38, 40 to sever the end of the web, an arm 42 to restore the lever 30, and a member 44 to open a switch 29, stop the motor 19 and bring the towbar to rest in the position shown in Fig. 1, the severed end of the web being removed so that the bar is ready to receive a new web. A feeler 27 responsive to the absence of a web or loss of web tension controls a switch 26 for the motor 17, which however is maintained in operation by an interlock link 28 while the motor 19 is in operation. A grounded shield is provided below the web path to the reel 16 to protect the processed web from electrostatic distortion.

Title: Ultra-violet sterilisers
IPC: A61L2/10
Filed: 1973-03-14
Abstract: 1459395 Photo-electric monitor for U V sterilizer BRITISH RAILWAYS BOARD 12 March 1974 [14 March 1973] 12170/73 Heading G1A In a U.V. sterilizer the radiation in the germicidal band 240-280 nm is converted into visible light after interaction with the material being sterilized, and the visible light is measured so that the sterilizer is switched off if the material receives insufficient radiation. In the Fig. water is sterilized by flow through a jacket around U.V. tube 1; the jacket has a window 6 so that U.V. passing through the water strikes a fluorescent powder 7 to emit visible light. This light is filtered at 8 to remove any  visible components generated by tube 1 and strikes silicon cell 9. The cell produces an A.C. output at twice the mains frequency driving tube 1, and the mean level of this A.C. is presented at 13. The mean level is compared with a reference at 14 to operate a relay 15 so that water can only flow through valve 17 when the U.V. is above a minimum level. An attenuator 10 can be operated to ensure that the valve 17 closes when the cell output signal falls. The conversion and detection may be used with sterilizers for solid, liquid or gas materials, and will switch off the apparatus if the source emission falls, e.g. due to source contamination, or if the material absorption becomes too large, e.g. due to metallic salts in a liquid being sterilized.

Title: Improvements in or relating to brakes for vehicles
IPC: B60T11/10
Filed: 1938-04-23
Abstract: 513,957. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, D. T. April 23, 1938, No. 12226. [Class 103 (i)] The master cylinder of a hydraulic brake system for vehicles and a mechanical system which may operate the same or other brakes are operated simultaneously by a floating lever. The pedal lever 21 is mounted by a pivot 22 on a link pivoted on the chassis 12 at 24. A master cylinder 10 connected by pipe lines 13, 14 to the front wheel brakes is operated by a push rod 19 connected to the lever 21 and the link 27 of a mechanical transmission for the rear brakes is also connected to the lever. The link 27 is connected to the brakes by an arm 35 pivoted to the chassis, a link 34 a lever 33 mounted by a link 30 so as to float and links 31, 32. Movement of the pivot 22 from the normal position is restrained by a rod 48 slidable in a bracket 46 on the chassis against the resistance of springs 52,- 53. Movement of the lever 21 thus applies force to the rod 19 and link 27 in a predetermined ratio and thus also to the front and rear brakes. Movement of the link 27 and rod 19 is respectively limited by stops 75, 74 so that in the event of failure of the connections to one pair of brakes the other pair will still be applied. The rear brakes may be applied also by a hand lever 40 connected by link 44 to the arm 35, lost-motion connections 39, 43'being arranged to prevent movement of one of the levers 21, 40 by operation of the other. Some of the brakes may have alternative hydraulic and mechanical applying means that are connected respectively to the mastercylinder and to the mechanical rigging of a system such as above described. The Provisional Specification includes also the subject matter described in Specification 513,937.

Title: Improved butyl rubber compositions
IPC: C08G18/69
Filed: 1952-05-19
Abstract: Butyl rubber compositions are improved by the addition of 0.01 to 1 part by weight of an aryl dinitroso compound or of an aryl dioxime and 0.1 to 20 parts of an organic compound containing at least one-NCO group, to 100 parts of the rubber.  Suitable isocyanates are mono-,di-, tri-and tetra-isocyanates, of which many examples are given, and mixtures of polyisocyanates resulting from the phosgenation of the condensation products of aryl mono primary amines and aldehydes or ketones as described in Specification 687,055, [Group IV (b)].  Examples of dinitroso compounds are the dinitroso derivatives of benzene, cymene, toluene and naphthalene.  Suitable dioximes, which are probably converted to dinitroso compound during working of the composition, are para-quinone, naphthoquinone, toluquinone, diphenoquinone and diquinoyl dioximes.  Mixtures of the dinitroso and dioxime compounds may be employed.  Other ingredients in the compositions include sulphur, zinc oxide, carbon black, paraffin wax, mercaptobenzo-thiazole, tetramethyl thiuram disulphide, stearic acid, silica, lead chromate and ferric oxide.  The compositions in the uncured state show improved plasticity and in the cured state have a higher modulus and abrasion-and stretch-resistance, less low temperature stiffness, greater resilience and resistance to air diffusion under pressure, and less cold flow.  Mention is made of their application in inner tubes and coated fabrics.
