Title: Heat shrinkable polytetrafluoroetbylene copolymer tubular film
IPC: B29C48/10
Filed: 1965-12-23
Abstract: 1,069,690. Heat shrinkable tetrafluoroethylene copolymer tubular film. E. I. DU PONT DE NEMOURS & CO. Dec. 23, 1965 [Dec. 31, 1964], No. 54574/65. Heading B5B. Heat-shrinkable tubular film is made by extruding in tubular form at 350 to 365 C. a copolymer of 5 to 95% by weight of tetrafluoroethylene and a terminally ethylenically unsaturated compound having a " specific melt viscosity" of 300,000 to 1,000,000 poises, quenching the extruded tubing by cooling it to a temperature of 130 C. or below, heating the tubing to 80 to 200 C., expanding the heated tubing diametrically by at least 9% and not more than 200% of its original diameter by applying internal gas pressure in the range of from 1À1 to 16 atmospheres absolute and cooling the expanded tubular film while maintaining its expanded diameter. The expression "specific melt viscosity " is defined as the melt viscosity determined at 380 C. in accordance with A.S.T.M. D-1238-52-T. Examples of comonomers copolymerizable with tetrafluoroethylene are the monoethylenic hydrocarbons such as ethylene, propylene, isobutylene and styrene, halogenated compounds such as 1,1-difluoro-2-chloroethylene, trifluoroethylene, chlorotrifluoroethylene, and hexafluoropropylene (also called perfluoropropylene). The preferred copolymer is a tetrafluoroethylene/ hexafluoropropylene copolymer having a specific melt viscosity within the specified range and wherein the hexafluoropropylene constitutes from about 11À2 to 12À8 mol per cent of the monomers. The expression " heatshrinkable tubular film " is defined as tubing which through the application of heat and internal gas pressure has been expanded in diameter and set in its expanded condition, so that, upon reheating, it will shrink in diameter towards its original dimensions. In use the tubing is slipped over an article to be jacketed, such as a pipe or roller and is reheated to a temperature above about 80 C. and less than its melting point, for example, with a " hot gas " gun at about 315 C. The tubular film is specified to have a diametral shrinkage of at least 5% and not more than 66À7%.

Title: Signal generating and control system for organ
IPC: G10H3/06
Filed: 1971-11-26
Abstract: 1360666 Electrophonic musical instruments OPSONAR ORGAN CORP 26 Nov 1971 [11 Dec 1970] 55011/71 Heading G5S An organ incorporating an optical disc record having a plurality of circular music tracks of variable opacity defining musical tones and accompaniment rhythm patterns is provided with light means to indicate the start of a musical measure on the accompaniment tracks. A further track, for producing a tremolo effect, and volume controlling means may be provided. The optical disc 12, Fig. 2, comprises tone tracks 22 and accompaniment tracks 24, each of the accompaniment tracks defining a rhythm pattern of musical notes lasting a whole number of musical measures along the 360 degree length of track. One new musical measure on each track begins on an imaginary line 47 and the other musical measure of each track begins on line 48. A synchronizing track 50 has transparent regions 52, 54 located on the lines 47, 48 and one end 58 of a light pipe 56 located above the synchronizing track receives light through the transparent regions from the light source 30. The other end 26 of the light source 56 is located on the panel of the organ such that the player sees a flashing light at the beginning of each musical measure. A tremolo effect is produced by means of a track 60, Fig. 3, which contains uniformly spaced transparent and opaque regions. A photo-cell 62, the resistance of which is dependent upon the intensity of incident light, is located to receive light passing through this tremolo track. The output from the photodetector 32 may be connected to the amplifier and loud-speaker via the photo-cell 62 to produce a tremolo effect or it may by-pass the photo-cell 62 by suitable arrangement of the switch 28. In order to control the volume while playing a swell-pedal 70 is used which controls the intensity of light incident upon a photo-cell 76 the resistance of the photo-cell being dependent upon the intensity of the incident light. The range of the volume control is initially set by means of a manual control 78 and the photocell 76 is connected in parallel with 78 to vary the volume within this preset range.

The initial slurry, which is preferably of rutile TiO 2 , suitably has a solids content of 100-900 g./l. and a temperature of 20-90 C., preferably 50-70 C. Suitable silicates are sodium or potassium silicates, particularly water-soluble sodium silicates with SiO 2 /Na 2 O ratios of 1À6-3À75. Suitable aluminium salts are aluminates of sodium or potassium. Steps (a) and (c) preferably precipitate 2-3% SiO 2  and steps (b) and (d) precipitate 5-8% Al 2 O 3 . The process may be applied to pigments which have been previously treated with oxides, e.g. TiO 2  and further coatings may also be applied. Preferably the pH is maintained between 6-8 throughout the process and mineral acids, e.g. HCI, H 2 SO 4 , HNO 3  and H 3 PO 4  may be used to precipitate the coatings. The coated pigments have improved hiding power.

Title: Carburetor having cold engine air/fuel mixture enrichment apparatus
IPC: F02M1/10
Filed: 1974-12-20
Abstract: 1475009 Extra fuel for starting and warming up FORD MOTOR CO Ltd 20 Dec 1974 [4 Jan 1974] 55305/74 Heading F1H The subject matter of the present Specification is the same as that of Specification 1475008 except for the means for providing extra fuel for starting and warming up, with which the claims of the present invention are concerned. In a carburetter, a fast idle cam 236, Figs. 12 and 14, is provided with two series of steps 250, 252, the former series being used except during starting and the latter being used only during starting to ensure that throttle plate 25, Fig. 12, which co-operates with the cam via lever 272 rigid with throttle shaft 24, screw 268, end 264 of lever 266 and plunger 254, is wider open than at the same temperature during running of the engine. The cam 236 is movable axially by being mounted on a sleeve 238 that is axially slidable on sleeve 220 in response to engine intake manifold vacuum applied to a chamber 310 to bring the series of steps 250 into line with the plunger 254 when the engine has started. The effect of vacuum in chamber 310 is transmitted to the sleeve 238 by plunger 314 and lever 288, which is moved from its broken line position to its full line position. As the engine warms up, bi-metal spring 322 rotates lever 228 which allows the fast idle cam to be rotated by gravity in an anticlockwise direction in Fig. 12 as leg portion 230 of lever 228 moves anti-clockwise, so that the plunger 254 no longer engages the series of steps on the cam and the throttle plate is able to reach its most nearly closed position. The lever 228 also rotates shaft 218 and thereby lever 216 to lift needle valve (72) and lower needle valve (140) Fig. 6 (not shown) which act as in Specification 1475008.

Abstract: 1,225,000. Measuring profiles photoelectrically. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. Nov.25, 1968 [Nov. 24, 1967], No.55721/68. Heading G1A. The profile of a surface is determined by directing radiation from a reference point at different angles on to the surface, receiving reflected radiation from the surface using a television camera and determining the position of the reflected radiation on the camera screen by timing the video pulse relative for example to the start of a scan by using a counter. Light from a laser E is reflected from the surface P to form an image P' on the sensitive screen of the television camera. The camera is so arranged that the position of P' may be determined by counting the lines between P' and B or counting during the time taken to scan a line extending from P' to B. In the latter case, the laser may be pulsed in synchronism with the start of the line scan. The distance EP is computed from the count output of the camera and given by analog and digital signals S A , S D . The profile of the object is built up by rotating the laser and camera about the axis ER and translating them stepwise along this axis. Radiation emitted by the object is excluded from the camera by an intererence filter. The following abridgments are included in this series since the Specifications were, through an error, not allotted to this Group. References to them will be found in the indexes to this volume.

The metal ring 8 provides a locating flange 11 and a support flange 9 embedded in and bonded to the outer wall 4.
