Abstract: 829.291. Adjusting draw links of tractors. CRUIKSHANK & CO. Ltd., SHANKS, T., and MARSHALL, J. Feb. 6, 1957 [Feb. 8, 1956], No. 3953/56. Class 79(1) Means for adjusting the draw links of a tractor to maintain the implement attached attached thereto in correct alignment comprises a laterally extending lug 11 secured to a draw link 8 and connected by a link 12 to a cranked lever 20 which is actuated by a manually operable member 15 by which the link 8 can be turned about its point 9 of pivotal attachment to the tractor. When the lever 20 is in its mid position, its pivotal connection 25 to the link 12 is substantially coaxial with the pivotal connection 9 of the draw link to the tractor. The lug 11 is constructed to permit vertical and horizontal movement of the links 8 and 12 which are connected, respectively, by a ball joint to the tractor and by a pivot 25 to a pair of arms 20. Rotation of the member 15 causes displacement of a nut like member carried by the arms 20 so that the latter swing about a pivot 22 on a lug 23 secured to the axle casing 7 of the tractor to adjust the link 8. The arms 20 and member 15 may be replaced by a linkage connected to a hand lever having a latch co-operating with a toothed sector. According to the Provisional Specification, the link 12 may be connected to a piston controlled by fluid pressure.

Title: Improved refrigerator
IPC: F25D11/02
Filed: 1955-02-10
Abstract: 765,251. Refrigerators. GENERAL MOTORS CORPORATION. Feb. 10, 1955 [March 25, 1954], No. 3977/55. Class 29 In a domestic refrigerator cabinet having a deep freeze compartment 14 and a food storage. compartment 16 with associated evaporators 56, 60 respectively, the relatively high temperature evaporator 60 is situated in a flue 70 and has the ambient air of the food storage compartment forced over it by means of a fan 76 located at one end of the flue, the air stream then passing over a receptacle 17 mounted on but spaced from the door 20. Refrigerant flows from the compressor 50 and condenser 52 by way of a fixed restrictor 54 to the low temperature evaporator 56, from which surplus refrigerant passes to the high temperature evaporator 60, then to an accumulator 64 and by suction line 62 back to the compressor. The fan 76 is offset a little from the flue 70 in order to avoid deterioration due to defrost melt water from evaporator 60. Air enters the flue by vent 72 and leaves at its upper end at 74. At the upper end of evaporator 60 is the thermostat bulb 80 controlling the compressor motor. When the motor is switched off refrigerant drains from evaporator 60 into evaporator 56, ensuring that the deep freeze is maintained; the frost on the former evaporator then melts and the melt water is led by the drainage slot 95 into the bottom portion of food compartment 16 from where it drains into a pan 102 placed near the condenser 52. The flue is preferably placed in the rear wall' of the storage compartment. The hydrator or similar recepacle 17 is supported on the fixed bracket 32 and guide 35 in such a way that rollers 31, 33 allow it to be swung against the door and held in that position when the door is closed by a catch 39. The lids 37 of the hydrator may be used as additional food storage shelves.

Abstract: 1,101,262. Vertical take-ofl aircraft. HAWKER SIDDELEY AVIATION Ltd. 29 Jan., 1965 [31 Jan., 1964], No. 4346/64. Headings B7G and B7W. [Also in Division F1] An aeroplane has narrow delta, compound delta or ogee wings formed of intersecting spars 13 and ribs 14 which at the inboard portions of the wings form bays for direct lift fans 16 driven by tip turbines supplied with by-pass air from by-pass gas turbine engines 24. The by-pass air passes through valves 29 which may alternatively direct the air through nozzles 27 for forward propulsion. The nozzles 26 for the hot flow are variable in area. The engines 24, elevons 25 and main undercarriage legs are mounted on a box-beam spar 23 aft of the fans. The thrusts of the fans may be varied selectively for roll and pitch control by varying the inclination of non-rotating tip turbine inlet blading (33, Fig. 5, not shown). The inlets and outlets of the fans are provided with vanes which are pivotable to close the bays to reduce drag, and to vary the direction of discharge. The vanes of groups of fans are selectively pivotable for yaw control and the pivoting is effected by bars connected to the vanes and raised and lowered by inflatable bags (Figs. 7 and 8, not shown). The vanes are closely spaced (e.g. one inch apart) to attenuate the fan noise, and may have skins of perforated, porous or semi-elastic material with an infilling of low density absorbent material.

Title: Improvements in and relating to the forming of hollow bodies
IPC: B29C51/06
Filed: 1969-01-27
Abstract: 1,202,516. Sheet forming. TETRA PAK A.B. 27 Jan., 1969 [7 Feb., 1968], No. 4472/69. Heading B5A. Hollow articles are made by sealing a heatsoftened sheet over an otherwise closed cavity and drawing the sheet using a male mandre initially located in said cavity, the sheet bein tightly applied to the mandrel by the reduction in pressure caused by the increase in volume due to the movement of the mandrel. In the preferred embodiment, a heat softened sheet 5 clamped over a cylinder 2, is pre-stretched by compressed air issuing through passage 9 and is then finally drawn to shape by upward movement of mandrel 3 located within the cylinder. The mandrel carries a flange 12 which is electrically heated and which severs the drawn article from the rest of the sheet upon further upward movement of the mandrel. Prior to the application of air to pre-stretch the sheet, the sheet balloons slightly upward due to the expansion of the air in the cylinder caused by the heating of the sheet by the heater located thereabove. In this way certain regions of the sheet become more heat-softened thus giving an article of more uniform wall thickness.

Abstract: 543,291. Artificial silk, films etc.; treating textiles with liquids dyeing processes; resinous condensation &c. products sizes. SOC. RHODIACETA. March 14, 1940, No. 4803. Convention date, March 25. 1939. [Classes 2 (ii), 2 (iii) and 15 (ii)] [Also in Group V] Filaments, threads, fabrics, and other articles formed of synthetic linear condensation polyamides are subjected to treatment with a swelling agent and to a loading treatment with metallic compounds: Salts of heavy metals, e.g., stannic chloride, may be used as loading agents. These may be converted to insoluble compounds by hydrolysis or by treatment with a fixing agent such as sodium phosphate or sodium silicate. The filaments may be passed through a solution or emulsion of a solvent or swelling agent and then into a bath of stannic chloride. The swelling treatment renders the materials more permeable by aqueous liquids and enables more of the loading agent to be absorbed. The tin salt is hydrolysed by washing with water and it is fixed by means of sodium phosphate. The materials may be again passed through a swelling bath before the treatment with phosphate. The materials may be subjected to a final treatment with sodium silicate: The swelling and loading may be carried out simultaneously, i.e., the swelling agent may be incorporated in the stannic chloride solution. The swelling agent may be phenol, m-cresol, formic acid, sulphuric acid, benzene sulphonic acid, dichlorhydrin, glycerine, or aniline. The loading with tin compounds improves the affinity of the materials for basic, acidic, or development dyes, or dyes used for cellulose acetate fibres. In an example, polyamide satin fabric is treated with stannic chloride solution containing phenol, and after washing, the fabric is treated with sodium phosphate and with sodium silicate. The fabric is dried and then dyed with Polar Red B. The loaded materials are less sensitive to the action of heat, e.g., in hot ironing treatments. Specifications 461,236, 461,237, and 504,714 are referred to. The Specification, as open to inspection under Sect. 91, comprises also the treatment in general of polyamide materials to increase their affinity or permeability for water. The treatment may be used in conjunction with sizing and dyeing treatments other than those employing mordants. The treatment diminishes the tendency of the materials to become electrified. In an example, a polyamide thread is dyed in a bath containing Induline N.B.S. and a small amount of formic acid. In another example, a warp of polyamide threads is sized with a solution containing gelatine, glycerine, water, and phenol. This subject-matter does not appear in the Specification as accepted.
