Filed: 1927-10-14
Abstract: 299,986. Andrew, T. Oct. 14, 1927. Air, moistening.-In a humidifying system of the kind described in Specification 246,589, the control of liquid to the atomizers is effected by air pressure resulting from the opening or closing of a leak port in a compressed air pipe. The hygroscopic strands a are secured between an adjustable slide b and a part c pivoted to a weighted lever d which actuates a small valve or leak port f<1> on the top of a fitting f through which air from a pipe g can escape; the pipe g is connected through a valve h with a compressed air main i. The pipe g is connected to one side of a diaphragm in a fitting n which actuates a valve to open or close communication between the main i and a pipe p. The air pressure in the pipe is utilized to control a diaphragm valve supplying liquid to the atomizers. Jets j draw moist air over the hygroscopic material.

Title: Polyurethanes derived from hydroxyl terminated diene polymers
IPC: C08L75/14
Filed: 1966-06-20
Abstract: 1,145,338. Polyurethane elastomers. SINCLAIR RESEARCH Inc. 20 June, 1966 [18 June, 1965], No. 27446/66. Headings C3P and C3R. Polyurethane elastomers are prepared by reacting an organic polyisocyanate with a polyhydroxy polymer having an average of at least 2À1 predominantly primary, terminal, allylic OH groups per molecule and being an addition polymer containing 0 to 75% by weight of the residue of an alpha-olefinic monomer of 2 to 12 carbon atoms, and 25 to 100% of the residue of an unsubstituted, 2-substituted or 2,3- disubstituted 1,3-diene hydrocarbon of 4 to 12 carbon atoms, the polyhydroxy polymer having a viscosity at 30 C. of 5 to 20,000 poises and a number average molecular weight of 400 to 25,000, and having more than 50% of its unsaturation in the main hydrocarbon chain. Exemplified polyhydroxy polymers used are polybutadiene homopolymers, a butadiene/ styrene copolymer, a butadiene/acrylonitrile copolymer, a polyisoprene homopolymer, an isoprene/acrylonitrile copolymer and a butadiene/2-ethylhexyl acrylate copolymer, all said polymers containing terminal allylic OH groups and being prepared by reaction of the monomers in the presence of hydrogen peroxide and isopropanol. Conventional aliphatic and aromatic polyisocyates may be used including polyurethane prepolymers containing terminal isocyanate groups. The reaction between the polyisocyanate and polyhydroxy addition polymer may be carried out by a one or two-step process. In the two-step process a stoichiometric excess of polyisocyanate is reacted with the addition polymer and the prepolymer so formed may then be reacted with, e.g. a glycol or diamine. In the one-step reaction the polyhydroxy addition polymer may be mixed with a conventional polyether or polyester before reaction with the polyisocyanate. The polyurethanes may be oil-extended by reacting the polyisocyanate with the polyhydroxyl addition polymer in the presence of 1 to 500% by weight of, e.g. paraffinic, naphthenic, aromatic or asphaltic oils. Fillers, especially carbon black and silica may be incorporated in the polyurethanes. The oil-extended polyurethanes may be blended with other conventional rubbers.

Filed: 1966-06-20
Abstract: 1,084,489. Lubricator. ATLAS COPCO A.B. June 20, 1966, No. 27508/66. Heading F2A. An airline lubricator has a casing 10, Fig. 1, having a compressed-air Venturi pipe 11 passing therethrough; and an opening 23, Fig. 2, which receives a valve-housing 15 therein. The valvehousing 15 has a needle-valve 16 therein which controls an oil-delivery bore 17 connected to the Venturi pipe 11. Each end of the latter has inwardly-threaded sleeves 12 welded thereto which receive couplings 13, 14 respectively; the coupling 13 being connected to a pressurized-air source and the coupling 14 being connected to a pneumatic appliance. A pressureconduit 26 is coiled about the axis of the Venturi pipe 11 and is connected to the Venturi pipe 11 at a position adjacent to the sleeve 12 which receives the coupling 13; and a suction-conduit 30 is coiled about the axis of the valve-housing 15 and is connected to the valve-housing 15 at a point upstream of the needle-valve 16. Both the pressure-conduit 26 and the suctionconduit 30 are provided with fine radial bores. In use, pressurized air is supplied to the coupling 13 and is transmitted to the interior of the casing 10, via the fine radial bores in the pressure-conduit 26 and through an end 27 thereof. Due to the increased velocity and the corresponding reduced pressure at the throat of the Venturi pipe, lubricant in the casing 10 is passed through the bore 17 and into the Venturi pipe 11. According to the Specification the fine radial bores in the suction-conduit 30 provide a substantially linear, instead of a quadratic, relation between the lubricant dosage and the air flow volume. The fine radial bores also prevent siphon action and unintentional emptying of the lubrication when in an abnormal position.

Title: Process and installation for cleaning and decontaminating garments
IPC: D06F43/00
Filed: 1972-06-14
Abstract: 1368892 Laundering arrangement SOC DE NETTOYAGE ET DE DESINFECTION D IVRY 14 June 1972 [9 Feb 1972] 27723/72 Heading D1A A process for cleaning and decontaminating i.e. removing particles and fibres remaining after cleaning garments comprises washing or dry-cleaning in a normal environment followed by decontamination in a "clean" room. Cleaning is accomplished in a washing or dry-cleaning machine 6 using an aqueous or chlorinated solvent and decontamination in a 'dry-cleaning' machine 13 using a fluorinated solvent which has a lower boiling point and soil removing ability than aqueous or chlorinated solvents as used in the first step. As shown in Fig. 2, garments are cleaned and dried in the machine 6 and tumble or tunnel drier 6a and then passed through a double door air-lock 5 into the clean room. The garments are then decontaminated in the machine 13 by operatives in "clean"-room kit inspected on hangers 15, folded on a table 17, sealed and packaged in polyethylene bags by unit 18 and removed through a second airlock 12 for sterilisation using ultra-violet radiation while within the packaging. The "clean" room I may be a horizontal laminar flow room (Fig. 1, not shown) with a blower wall (2a) and an eduction wall (3a) on opposite sides or a turbulent flow clean room (Fig. 2) with clean air diffusers 19 and air outlet flaps 20. The decontamination machine 13 (Fig. 5) abuts a seal (22) around an opening 14 in the "clean" room (Fig. 3, not shown) and has a single door in this opening 14. It comprises a drum 31, a pin filter 44, an electrostatic fluff filter 48, a pump 30, a solvent tank 33, a still 41 and a filtration unit with a 20 micron filter 26, a 5 micron filter 27 and a 0.45 micron filter 28 which may be used in series or be bypassed as desired. In use the machine 13 is loaded, evacuated and the drum rotated while solvent including an antistatic additive is circulated through the first filter 26 only before discharge of the solvent to the still 41 and a first spin-drying. Then in a further cleaning cycle solvent is added again and recirculated through the full filtration unit before being discharged to the reservoir directly. The laundry is spun dry and the drum walls heated, the solvent vapour going to the still 41. The laundry is then unloaded and packaged as described above.

Title: Improvements in colour analysis of multi-colour patterns
Inventor: HASSING OLUF
IPC: G01J3/46
Filed: 1965-07-01
Abstract: 1,121,283. Local copying by scanning. WALL PAPERS MFRS. Ltd. 13 June, 1966 [1 July, 1965], No. 27856/65. Heading H4F. A device for correcting the width of scanned patterns and forming records thereof comprises a pick-up head 17, Fig. 1, mounted on a subcarriage 14 on a main carriage 16, and one or more recording heads on other main carriages, the main carriages being linearly displaced at the same rate during scanning and the subcarriage 14 being moved relative to the main carriage 16 at a rate proportional to the rate of the main carriage 16 in a direction parallel to the direction of movement of the main carriage. Main carriage 16 slides on bar 27 causing pick-up head 17 to scan a pattern attached to rotating drum 18. The additional movement of the sub-carriage 14 on supports 15 is provided by means of a fixed sine bar 1 inclined at an angle to the direction of movement of main carriage 16 so that as the main carriage moves bar 3 which is spring-held against bar 1 is slidably displaced in guide 4 causing a triangular plate 5 to pivot about 7. Plate 5 has a slot 6 in which runs a pin 8 fastened to a rod 9 which is fixed to a vertically adjustable threaded block 10. With support 10 in the position shown, rod 9 and sub-carriage 14 move to the left with respect to the main carriage when the main carriage moves to the right, thus correcting for a too narrow pattern. If the pattern is too wide, blocks 10 and rod 9 are moved below pivot 7. For the pick-up head to have the same traverse as the main carriage, pin 8 is located at pivot 7. The correction may be applied to the recording heads instead of the pick-up head. If the pattern to be scanned is symmetrical and the artist draws one-half only, the pick-up head carriage 16 mounted on slide bar 27 is clutched to a moving bar 21, Fig. 2, for the first half of the scan and then clutched to a moving bar 22 so as to return to the starting point of the pattern, recording head carriage 20 being fixed to bar 21. The width correction may be applied to this half-pattern scanning and to the process described in Specification 1,013,423 in which one or more colour shades from a coloured pattern are recorded.

Abstract: 704,080. Retractable undercarriages for aircraft. BOULTON PAUL AIRCRAFT, Ltd. Nov. 19, 1951 [Nov. 17, 1950], No. 28212/50. Class 4 A retractable aircraft undercarriage of the kind having a break back strut for holding a wheel mounting in the extended position and interengaging locking members carried one on the wheel mounting and the other on the aircraft for holding the mounting in the retracted position has one element of a retraction jack operatively connected to the wheel mounting and the other element operatively connected to the break-back strut through a member movable relative to said strut within the limits of a lost motion mechanism, said member being operative in one direction of said relative movement to release the interengaging locking members holding the undercarriage in the retracted position, and in the other direction of said relative movement to release locking means tor locking the break-back strut in the extended or straight position. The undercarriage leg 1 is pivoted at 2 to the aircraft structure for sideways retraction, an arm 13 fast with the leg being connected to one end of a retraction jack 9. the other end of which is connected at 10 to an arm (not shown) fast with a rotatable shaft 8. A break-back strut comprising members 4 and 5, pivotally connected at 6, is freely pivoted at 7 to the leg 1 and to the shaft 8, which carries adjacent to the arm 4 a plate 28 having a slot 29 engaging with a peg 30 fast with the arm 4. A further arm 31 fast with the shaft 8 has a pivotal connection 32 with one end of an articulated spring loaded rod 33 the other end of which is connected to a hooked catch 34 pivoted to the arm 4 to engage a roller 36 on the arm 5 when the break-back strut is extended. An up-lock arm 20 is pivoted at 24, Fig. 1. to the aircraft structure and carries a roller 26 acted upon by a cam 27 fast with the shaft 8. With the undercarriage in the position shown in Fig. 1, initial. extension of the jack 9 rotates the shaft 8 and acts on the linkage 33 to release the catch 34, 36 and free the strut 4, 5 with lost-motion movement of the slot 29 over the pin 30. Further extension of the jack causes the plate 28 to act on the pin 30 to break the strut 4, 5 and initiate retraction of the leg 1 from which position continued extension of the jack exerts a leverage on the shaft 8 and the arm 13 to raise the leg to the retracted position where a roller thereon engages the catch 20. During lowering movement, initial movement of the jack rotates the shaft 8 in the opposite direction so that the cam 27 acts on the roller 26 and the lever 20 to release the roller on the leg, the mechanism then operating in the reverse manner to that described.
