Abstract: 1,086,956. Forming lateral necks on hollow thermoplastic bodies. DYNAMIT NOBEL A.G. Oct. 2, 1964 [Oct. 2, 1963], No. 40358/64. Heading B5A. In a method of forming a lateral neck on a hollow thermoplastic body, an opening having a diameter less than the internal diameter of the neck is formed in the wall of the body, the wall is heated in the region of the opening and the wall surrounding the opening is gripped by means of a tool arranged externally of the body and drawn outwardly and expanded by the tool until the neck diameter is of the desired value after which the thermoplastic material is cooled while the tool maintains the internal diameter of the neck constant. As shown, a pipe 1 is clamped between flange 10 screwed on to cylinders 11 of supports 15 each movable on guide rails 12 on a table 13 and secured thereto by a clamp 14. A plate 17 covers the pipe on the side having the opening 5, an opening 16 in the plate corresponding to the opening 5. The tool for forming the neck comprises a mandrel 6 having a spiral worm 7 at one end and connected to a spindle 9 at the other. The spindle has a screw-thread of smaller pitch than the spiral worm 7 and is mounted in a threaded block 18 fixed on a plate 19 which can swivel about pivot 20 and be locked to the table by clamping means. In operation the spindle is rotated either manually or by a motor causing the mandrel to penetrate the opening 5 and enter the pipe whereby the wall surrounding the opening is forced outwards and expands around the mandrel until the final position is reached. Cooling is effected and the mandrel retracted after which an auxiliary pipe can be inserted into the neck and adhered thereto. The mandrel may be shaped to provide a neck which tapers and may be of the same diameter as the internal diameter of the pipe 1.

Title: Improvements in or relating to electric typewriters
IPC: B41J19/60
Filed: 1962-01-11
Abstract: 963,326. Typewriters. IMPERIAL TYPEWRITER CO. Ltd., A. B. PATEMAN, and H. GILBEY. Jan. 4, 1963 [Jan. 11, 1962], No. 1148/62. Heading B6F. An electric typewriter has means for intermittently disconnecting the driving motor as the carriage approaches the carriage-return position thus slowing down the carriage before the stops engage one another. The motor 12 is connected through a clutch box 14 either to a belt drive 11 for the power shaft of the type action or to the carriage-return cable. In circuit with the main switch 24 of the motor 12 is a microswitch 26 which has an operating member 31 engaged by a screw 57 on a member 47 vertically slidable by means of pin-and-slot devices 46, 52. The member 47 is normally held raised by a spring 54 but carries at its upper end a roller 62 which can be engaged by raised parts 43 on a bar 42 to move the member downwardly to open the switch 26. The bar 42 is secured to a bracket 38 carrying the carriage-return margin stops 37 on the margin rod 35, and another bracket 39 on the rod. As the stop 37 approaches the fixed stop 36, the raised parts 43 operate the switch 26 so that the motor is alternately disconnected and reconnected thus slowing down the carriage movement. To ensure that the motor 12 is not disconnected by the raised parts during typing movement of the carriage or back-spacing, another switch 28 is in parallel with the switch 26 and is kept closed during such movement by an arm 33 operated from the clutch-box 14. In a modification (Fig. 5, not shown), the second switch is omitted, and the roller 62 is carried by a bracket pivoted on the member 47 and operating to move the member 47 downwardly only during carriage-return movement.

Title: Hydraulic boost mechanism
IPC: B60T13/16
Filed: 1972-01-11
Abstract: 1309059 Brake boosters BENDIX CORP 11 Jan 1972 [28 Jan 1971] 1287/72 Heading F2F  An hydraulic boost mechanism comprises a housing 16 having a bore 18, a piston reciprocable in the bore and dividing the latter into two chambers 32, 34 located at respective ends of the piston, inlet and outlet ports 20, 78 and a working port 26 in communication with the bore, and a valve 58 slidably positioned within the piston for controlling fluid flow between the ports and the chambers; the piston comprises two telescopically related members 35, 36 each of which is circumferentially recessed for maintaining continuous communication with an associated port to obtain maximum piston stroke for a given bore length. As shown, a piston 35 is telescopically slidable in a sleeve 36 slidable in the bore 18 of the housing 16, the piston actuating a brake master cylinder through a force transmitting rod 60. The device is connected to an engine driven pump via the inlet port 20 and via the working port 26 to a steering gear 14 communicating with the pump via a return line 28. In operation, with the pump 12 operating, hydraulic fluid circulates freely through port 20, recesses 40 and 52 respectively in the sleeve and piston, passage 53 the opening between the valve seat 72 and valve ball 68, passage 55, recess 42 in the piston, passage 44, recess 38 in the sleeve, port 26, steering gear 14 and to the pump. Movement of the member 74 to operate the booster firstly seats the valve member 75 on the ball 68 to cut off chamber 34 from port 78 and then connects that chamber to the inlet 20, further movement of the members 74, 75 seating the ball on the seat 72, the chamber 34 then being exposed to the full main pressure source except that which is by-passed by the passages 71 to provide for operation of the gear 14. The piston 35 is thereby moved to the left to act on the rod 60 and activate the master cylinder. Release of the member 74 allows return of the piston and valve 58 to the initial positions as shown. In the event of insufficient supply of fluid from the pump, the deficiency is sensed by flow sensitive device 92 which actuates an electric pump 86 connected to an inlet port 89 communicating with recesses 40, 52, passage 53, the opening between the valve seat 72 and ball 68, passage 55, recess 42, passage 44, recess 38 and port 26. This subsidiary source from the pump 86 acts through conduit 102 and passage 100 on the valve 96 to shut off communication with the port 26 and the rest of the hydraulic system including the gear 14, circulation of fluid within the piston and valve occuring through the shunt path 106 connecting the recesses 38 and 40 of the sleeve 36. Whether the main or subsidiary source of fluid is producing movement of the piston means 30, comprising the piston 35 and sleeve 36, application of pressure fluid to the chamber 34 advances the piston into the sleeve until the land 48 of the piston contacts the sleeve end 50, communication between the ports 20 and 26 being maintained.

Abstract: 1,169,455. Electrostatic coating; coated cathode ray tubes. RANSBURG ELECTROCOATING CORP. 11 Jan., 1967 [28 Feb., 1966], No. 1439/67. Heading B2J. [Also in Divisions C4 and H1] Charged phosphor particles are electrostatically applied. under the influence of an electric field, to a face of a Cathode ray tube which has first been coated with a sensitized binder. The apparatus comprises a deposition chamber 11 a gas-permeable plate 28, to support powder particles, mounted in the chamber, an electrode assembly including annuli 39 and points 42, on a charging head 38 and pins 43 on the plate, an earthed support 22 for the C.R.T. face 10 above the electrode assembly, means 34 to force air or other gas through the plate to form a fluidized bed of particles with a cloud of particles above it, and means 44 to establish an electric field, charge the particles and deposit them on the face. Phosphor particles flowing over the chamber edges are caught by a jacket 14 and pumped to a reservoir 19. The support 22 is rotated by a motor 21. Alternatively the plate 28 may be rotated, or both support and plate may be fixed. A colour television tube face is prepared by applying to the uncoated face a light-sensitive binder e.g. comprising 3% polyvinyl alcohol (P.V.A.) 0.5% ammonium dichromate in 1:1 isospropylalcohol/water. After drying the tube face is coated with a first phosphor and a dotted image-producing screen layed over the phosphor screen which is then exposed to light. The light polymerizes the P.V.A. Unpolymerized P.V.A. and phosphor not within the dotted areas is removed by rinsing with water. Second and third offset phosphor dot patterns are similarly applied to second and third polymerizable binder coatings. A monochrome tube is prepared by light exposure without the image-producing screen.

Title: Improvements in or relating to a method of treating a photographic silver image and the product resulting therefrom
IPC: G03C7/26
Filed: 1948-01-19
Abstract: 664,242. Colour photography; iron toning. CINECOLOR CORPORATION. Jan. 19, 1948 [Oct. 6, 1947], No. 1584/48. Class 98 (ii). To avoid the masking effect of a first-made prussian blue image on a second image made in the same emulsion layer, a first latent image is produced principally in the outer strata of a silver halide emulsion, developed, toned prussian blue in a series of solutions so adjusted that the formation of prussian blue proceeds at successively slower rates, whereby the prussian blue particles are more highly dispersed in the deeper strata of the emulsion, the prussian blue is converted to ferric hydroxide, the silver ferrocyanide formed by the toning solutions is reconverted to silver bromide, a second image is printed, developed, toned or dye toned and, finally, the ferric hydroxide is reconverted to prussian blue. The re-formed silver bromide is more sensitive in the deeper strata of the emulsion, presumably due to the presence of highly dispersed particles: The prussian blue may be formed at successively slower rates by variation of the toning solution during such formation, but preferably separate solutions are used, the later ones having a lower ferric ion concentration. Examples of the solutions are provided. Conversion of the prussian blue image into ferric hydroxide and resensitization of the silver ferrocyanide may be effected by a single solution containing sodium carbonate and potassium bromide. The Specification as open to inspection under Sect. 91 comprises also variable speed nickel, copper, cobalt and uranium toning. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to liquid-immersed electric switches
IPC: H01H33/98
Filed: 1933-01-18
Abstract: 410,909. Liquid-break switches. COATES, W. A., Walford Lodge, Dunham Road, Bowdon, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 18, 1933, No. 1671. [Class 38 (v).] Arc-rupturing devices.-In switches of the kind in which the contacts are liquid-immersed and arranged to provide a plurality of breaks in series in succession, whereby the arc produced at the final break is blown out by a blast produced by pressure generated by the preliminary arc in an explosion pot, a plurality of preliminary breaks in series is caused to occur simultaneously, so that the blast-pressure will be due to a number of arcs and will be adequate to rupture smallcurrent arcs at high voltage. As applied to a multiple cross-jet arrangement in which the blast is forced through a passage 7, across the arc formed in a space 3, and out of passages 4, the upper explosion chamber 13 contains auxiliary fixed contacts 14-20 moulded in recesses in insulating material 24 such as that known under the Registered Trade Mark "Bakelite." Contact 14 is connected by a strap 21 to the central conductor 22 and the remainder are interconnected as shown in Fig. 2, by straps 23. These co-operate with a series of movable contacts 26-32, each of which is spring-pressed towards its co-operating fixed contact and is slidable in a recess in the upper part 34 of a similar moulded insulating block secured on the stem 11 of the spring-pressed contact 10 which co-operates with the moving contact 2. The contacts 26- 31 are interconnected by conductors 41 in channels 39, Fig. 3, and 32 is connected to 11. Thus, when 2 is lowered, the spring 43 holds contact 10 in engagement with it, but a plurality of arcs are formed between the contacts in chamber 13, the current flowing up and down as shown by the full-line arrows in Fig. 1. The number of arcs causes adequate pressure to be developed even when small currents are being broken. By spacing apart the pairs of contacts in a graduated manner, the effect will be obtained that, with larger currents, two or more of the closely-adjacent arcs will coalesce and enhance the blast pressure.
