Abstract: 1,028,669. Aircraft undercarriages. DOWTY ROTOL Ltd. Nov. 12, 1963 [Nov. 13, 1962; Nov. 16, 1962], Nos. 42889/62 and 43475/62. Heading B7G. A retractable aircraft undercarriage has a leg pivotally connected to the aircraft structure by links 16, 17 and a fluid pressure operated jack 26 pivotally connected to the aircraft structure and the leg for raising or lowering the aircraft by pivoting the leg about a hinge 18, to facilitate loading. A separate retraction jack 20 and the jack 26 is then connected to the leg by a link 30 which allows the leg to pivot about the hinge 18. The jack 26 contains an internal lock, and the link 30 is secured to the leg by locking means 33, 34 when the leg is not retracted. The leg may also be telescopic, and may be shortened or extended to vary the aircraft height further by withdrawing liquid from or introducing liquid into a shock absorber of the leg. As described, the undercarriage retracts forwardly (to the left in the figure), and pivots rearwardly to lower the aircraft, and the retraction jack has some lost motion so that it does not restrict the lowering operation. The invention may be applied to nose or main landing wheels. The movement of the tail of the aircraft may be accentuated by extending the main wheels and shortening the nose wheel, or vice versa.

Title: Improvements in or relating to the manufacture of electrophotographic materials
Inventor: CASSIERS PAUL MARIA
IPC: B05D1/26
Filed: 1964-10-26
Abstract: A photoconductive layer is made by melt-extruding a photo-conductive polymer or a photoconductive substance which may be mixed with a film-forming thermoplastic polymer as a binder. The binder preferably has a specific resistivity of 1010 ohm. cm.  The ratio of dispersed photoconductor to binder may be increased at the surface of the layer by extruding the melt onto a porous base with or without subsequent heating so that the binder penetrates the base.  Alternatively the surface of the layer may be ground, the binder solvent extracted or photoconductive powder pressed into the surface of the layer whilst still soft.  The photoconductive particles may thus protrude from the surface or be covered with only a thin layer of binder.  A self-supporting sheet may be made into which metal or carbon particles may be pressed whilst the surface is soft, to give a conductive backing, alternatively a conductive layer may be formed by vacuum coating on or applying a liquid to the sheet.  In other embodiments, the extruded melt is applied to a substrate, e.g. aluminium, paper or aluminium foil and paper, using a roller or a curtain coater.  Additives such as butyl or zinc stearate or paraffin oil, may be used to act as lubricants whilst nonbutyl phosphate may be used to increase dark-decay time.  Natural or synthetic waxes may also be added.  Photoconductors exemplified are ZnO, Cds, pp\sv dibenzoyl-aminostilbene, 2,5 diphenyloxadiazole, 2,5 diphenylthiadiazole, 2-(p-dimethylamionphenyl) -3-phenyl quinoxaline. The binder may be polyethylene, polypropylene, a polymer or copolymer of vinyl chloride, vinylidene chloride, acrylonitrile, butadiene or styrene, polycarbonates, polyester, e.g. polyethylene sebacate, polyaceals, e.g. polyformal, polyethers, silicone resins, cellulose, actatebutyrate.  Transparent photoconductive elements may also be made.

Title: Process for the manufacture of vinyl ester polymers and copolymers
IPC: C08F18/04
Filed: 1960-12-19
Abstract: Polymers of vinyl esters are manufactured by polymerizing the monomers in the presence of a catalyst comprising a mixture of a trialkyl aluminium and an organic peroxide or hydroperoxide. Specified vinyl esters are vinyl acetate, vinyl propionate, vinyl butyrate and vinyl stearate.  The aluminium trialkyl may contain 1 to 12 carbon atoms in each alkyl group, e.g. aluminium triethyl or triisobutyl.  The peroxide may be an alkyl peroxide, ketone peroxide, aldehyde peroxide, acyl peroxide or alkyl hydroperoxide, e.g. diacetyl peroxide, dibenzoyl peroxide, dilauroyl peroxide and t-butyl hydroperoxide. The polymerization may be effected batchwise or continuously in the presence of solvents and may be accelerated by small amounts of oxygen.  The monomer and/or catalyst components may be added continuously or incrementally.  Examples describe the polymerization of vinyl acetate in the presence of (1) diacetyl peroxide and triethyl aluminium, (2) dibenzoyl peroxide and triisobutyl aluminium and (4) t-butyl hydroperoxide and triethyl aluminium; and vinyl butyrate in the presence of (3) diacetyl peroxide and triethyl aluminium. The products may be converted to polyvinyl alcohol or polyvinyl acetals.  Specification 367,102 is referred to.

A conveyer 21 carries empty carriers, which are loaded by hand and transferred by a device 25 to a conveyer 22, which in turn carries them to a feeding station 2. An indexing table 1 conveys the loaded carriers sequentially to the cutting station 4, a station 5 where sleeves 55 are applied to the conductors, the stripping station 6, terminal crimping stations 7, 8, a testing station 9 where an electrical continuity test is made on each conductor, a station 10 where the sleeves 55 are positioned over the crimped terminal portions, a station 11 where an identifying label 57 is attached to the conductor 54d, a carrier rejection station 12 and a carrier ejection station 13, where the carriers are passed to either of conveyers 24, 23 respectively. A sensing device (not shown) is provided for detecting unloaded carriers in advance of the station 4. Each carrier comprises a metal container having a plate 32 formed with a U-shaped opening 33 and a spring clip 35 on a base. The telephone cord has a grommet at either end, one of which engages in the opening 33 and the other in the spring clip 35 while the insulated conductors are held individually in slots in a pair of plates 37. A pillar 36 is provided so that the ends for conductors of greater length than the others are in alignment with the ends of these conductors.

Abstract: 1,066,857. Seals. JOHNS-MANVILLE CORPORATION. Nov. 6, 1963 [Dec. 21, 1962], No. 43823/63. Heading F2B. A fluid seal for relatively rotatable parts comprises a U-shaped ring 40 of elastomer material which co-operates with an annular ring 30 of low-friction synthetic resinous material and includes a dynamic lip section 42 having a tapered circumferential surface engaging a tapered portion on the annular ring, the annular ring in operation being extruded towards the dynamic lip. The ring 40 may be provided with a metal reinforcing ring 56 and, if desired, bonded to its casing 20. Preferably, the ring 40 is made of a fluoroelastomer comprising at least 60% by weight of fluorine and the annular ring 30 is made of P.T.F.E. Fluid pressure acting on the seal, it is stated, causes the ring 40 to ride-up the inclined surface of the ring 30, thereby reducing interference on the shaft 50; this movement causes part of the ring 30 to be extruded under the lip 46, Fig. 4 (not shown), thereby imparting the low-friction characteristic to the lip. Fig. 5 shows the seal as provided with a ring 58 stretched tightly over the shaft to prevent excessive extrusion of the ring 30 through the clearance space; also shown, is a securing plate 60. Instead of being mounted as shown for engaging the moving shaft, the seal may be actually mounted on the shaft, Fig. 6 (not shown).
