Title: Improvements in and relating to automatic needle threader and presser foot for a sewing machine
IPC: D05B87/00
Filed: 1939-12-13
Abstract: 533,899. Sewing-machine needle-threaders. LOUNSBURY, J. C. Dec. 13, 1939, No. 32127. [Class 112] A needle-threader mounted on the presser foot of a sewing machine comprises a thread-pusher 27 hinged upon a lever 31 pivoted at 32 and a latch plate 37 having a sliding-rocking pivot 38. The lever 31 and the latch plate are urged apart by a spring 35. Fig. 3, shows the device in its inoperative position. In operation, the thread is slipped by hand through a slot 22 into position in front of the pusher. The needle is moved into its lowest position and the latch plate 37 is moved by hand to the position shown in Fig. 4, where it is retained because a pin 43 is in a transverse portion of an L-shaped slot. In this condition, the pusher is urged by the spring 35 into the thread groove of the needle and when the needle is raised the pusher will pass, with the thread, through the eye. In this movement, the lever 31, which carries the pusher meets the latch plate 37 and moves it transversely thereby releasing it and allowing the spring 35 to return it to the position shown in Fig. 3. In doing this, the latch plate presses upon a leaf spring 36 and causes it to nip the thread that has been passed through the needle eye.

Title: Improvements relating to the neutralisation and drying of sulphate of ammonia
IPC: C01C1/249
Filed: 1921-12-01
Abstract: 183,089. Weyman, .G. Dec. 1, 1921. Ammonium sulphate.-Commercial ammonium sulphate is neutralized by the addition of a solid neutralizing-agent, preferably in powdered form, to the acid salt while it is being centrifuged. The neutralizing-agent, which should be one capable of evolving a gas when in contact with the warm salt, is preferably added after the bulk of the mother liquid has been expelled, and is introduced into the centrifuge so that it becomes spread on the inner surface of the crystals in the lower portion of the basket. The flow of the remaining liquor then disseminates the neutralizing-agent, or the gas evolved therefrom, throughout the mass. The salt is preferably discharged from the centrifuge before neutralization is complete, the continued decomposition of the reagent in contact with the hot salt serving to complete the process and, in addition, to dry the salt. The amount of neutralizing-agent required may be less than the theoretical. A centrifuge with means for distributing a neutralizing-agent in the basket thereof comprises a casing a, containing the basket b. The neutralizing agent is supplied from a worm feeder d, through a conduit e, the rate of feed cf the reagent being controlled by the turning of the handle g. Air under pressure may be blown in through the pipe f to facilitate the distribution of the reagent, which may be further distributed by means of chains k, attached to a ring l, so that they fly outwards, and also by means of the conical bottom h of the centrifuge.

Title: Method for the inspection of materials, especially of a particular zone thereof, with the aid of ultrasonic waves
IPC: G01N29/06
Filed: 1952-12-19
Abstract: 726,824. Ultrasonic couplings. RONTGEN TECHNISCHE DIENST N.V. Dec. 19, 1952 [Dec. 19, 1951], No. 32244/52. Class 40 (4). [Also in Group XXXVIII] The probe 61 of an ultrasonic inspection system (see Group XXXVIII) is automatically traversed over the material under inspection and effective coupling is ensured by a device shown in partially cut-away perspective in the Figure. Longitudinal beams 50 and 51 carry shafts 52 and 53 driven by a synchronous motor 58 on which are mounted wheels 54 to 57. The diameter of the shafts between the wheels is slightly smaller than the diameter of the wheels themselves, and has a felt covering 59. This part of the shafts is adapted to receive an endless belt 60 made of material suited to provide effective acoustic contact between the work and the probe 61, e.g. rubberized nylon. The thickness of the belt is such that it does not protrude beyond the wheels. As the device is driven over the work material to be inspected there is thus no relative motion between the belt 60 and the work material, and a sliding action between the belt 60 and probe 61 which has a smooth operative surface pressed onto the belt 60 by spring 63. A means (not shown) is provided for moistening the felt 59 with a fluid such as oil or alcohol; as a result the belt 60 becomes moistened and ensures effective acoustic contact with the probe 61. Preferably, the wheels 54 to 57 and beams 50, 51 are made of magnetic material and means are provided on the device for producing a magnetic flux (e.g. beams 50 and 51 may comprise permanent magnets) such that the device holds onto the work material over which it travels at a speed of some 2 metres per minute.

Title: Nonthrombogenic Films and Hollow Fibers Consisting of Organic High Polymers
Inventor: OJA PHYLLIS D
IPC: C08J3/00
Filed: 1967-07-13
Abstract: 1,195,384. Non-thrombogenic films and hollow artificial fibres. DOW CHEMICAL CO. 13 July, 1967 [21 July, 1966], No. 32307/67. Heading B5B. [Also in Divisions B1 and C3] Thrombogenicity is inhibited in articles of organic film or fibre-forming polymeric material having dialkylaminoalkyl groups attached to the polymer chains through ether linkages by reacting the material with an alkyl halide and reacting the resultant product with an alkali metal salt of a cationic group-containing antithrombogenic compound such as heparin or a heparinoid compound. The term "articles" is defined as meaning films, thin, pliable non- fibrous sheets and hollow fibres having an axial cavity extending throughout their length so that liquid can flow through the fibres from one end to the other. The dialkylaminoalkyl polymeric material may be prepared by converting at least a portion of the hydroxyl groups of a hydroxyl group-containing polymeric material to oxy alkali metal groups and reacting the product with a haloalkyl dialkyl amine. The hydroxyl group-containing material may be a cellulose, such as a regenerated cellulose, or may be prepared by treating a film-forming and/or a fibre-forming cellulose ester, such as cellulose acetate, with an aqueous solution of an excess of an alkali metal hydroxide. The aqueous solution may contain a water-soluble swelling agent for the cellulose ester, such as dimethyl sulphoxide, dimethylformamide, N-methylformamide, dimethylacetamide or tetramethylene sulphone or a ring-substituted derivative thereof. The article of the invention may be in the form of one or a bundle of hollow fibres. The hydroxyl group-containing polymeric material may be polyvinyl alcohol, hydroxy ethyl cellulose or hydroxyethylcarboxymethyl cellulose. Alternatively, polymeric materials that have grafted upon their surfaces hydroxy-containing materials may be employed, e.g. hydroxy terminated grafts of alkylene oxides on polyamides and polyesters. Normally the polymeric materials that are treated are in the desired article shape namely a film or fine hollow filaments, before being heparinized, but the polymeric material may be treated while in the form of granules, powders or other shapes and subsequently shaped into films or hollow filaments. The latter may be produced by melt spinning cellulose acetate plasticized with tetramethylene sulphone or a related ring-substituted derivative combined with a polyol. An artificial kidney may be comprised of a number of fine filamentary hollow fibres that have been treated according to the invention.

A timer for use in a liquid fraction collector comprises a lead screw 2 driven at a constant speed by a motor 1 and a gear-box 3 and a nut 5 axially movable along the lead screw between stops 9, 10, an output device being operated when the nut reaches at least one predetermined position along the lead screw and the motor being reversed on engagement of the nut with either of the stops. The stops 9, 10 are mounted on oppositely threaded portions 11, 12 of a control bar 13, the distance apart of the stops being adjustable by a knob 14. The nut 5 and the stops 9, 10 are slidable on a fixed guide rod 6 so that when the nut engages the stop 9 for example, the bar 13 is moved away from the spring operated arm 16 of a pair of bi-stable micro-switches 17. One of the switches provides the required electrical output whilst the other reverses the direction of the motor. In a modification the positions of the stops are independently adjusted by separate knobs which may be calibrated in suitable time intervals.

Abstract: 1395260 Operating I C engines SIEMENS AG 12 July 1972 [16 July 1971] 32674/72 Heading F1B In a method of operating an I. C. engine using a catalyst for cracking a fuel containing carbon and hydrogen to produce a gas or vapour which is supplied with oxygen containing gas to engine 2, fuel mixed with a sub-stoichiometric quantity of oxygen containing gas is ignited and passed over the catalyst to the engine and when the catalyst starting temperature is reached the oxygen/fuel ratio upstream of the catalyst is reduced. When or after the reforming temperature for a fuel/exhaust gas mixture is reached, part of the oxygen containing gas and fuel are replaced with exhaust gas and the mixture supplied to the catalyst is heated by heat exchange with the exhaust gas and/or the mixture downstream of the catalyst. Air and fuel are mixed in fuel metering device 14 and fed via heat exchangers 9 and 8 to porous bricks 5 carrying catalyst and the cracking product passes via heat exchanger 9 and is mixed with secondary air admitted through valve 13 before going through throttle valve 11 to the I. C. engine 2. The engine exhaust gas passes via pipes 22, 21 and heat exchanger 8 to exhaust outlet 23, which may be provided with means to afford flow resistance and cause sound damping. After the reforming temperature is reached, valve 19 is opened and some exhaust gas is passed to the fuel metering device 14 via pipe-line 18. During warming up an ignition device 7 operates but when the catalyst has reached its starting temperature as detected by temperature sensing means 6, the device 7 is no longer used. A control and regulating device 24 responds to catalyst temperature and the setting of throttle valve 11 to operate regulators 25 by way of lines 26 and thus control the flows of fuel, primary and secondary air, mixture and exhaust gas recirculation. The highly porous sintered bricks 5 are constructed with a plurality of parallel gas ducts.

Abstract: 934,363. Axial-flow compressors. ROLLSROYCE Ltd. Sept. 20, 1961 [Sept. 26, 1960], No. 33011/60. Addition to 869,576. Class 110 (1). A compressor for a gas-turbine engine comprises a compressor casing with an apertured portion through which air, compressed by the compressor, is bled, a valve bond encircling the casing and mounted for partial radial movement with respect to the casing and positionable in at least one position in addition to the positions at which the apertured portion is fully opened and fully closed, and means for progressively moving the valve band into and retaining it in each of these positions. A flat strip 32, Fig. 2, which encircles a casing 14 of a compressor 10, Fig. 1, is guided between radial flanges 17, 18 circumferentially spaced on the casing 14. The strip 32 is urged against lips 20, 21 by leaf springs 33 also arranged circumferentially but riveted to blade platforms 22. When the strip is in the position shown in Fig. 2, air compressed in the compressor passes through apertures (not shown) between the stator blades, through openings between casing portions 23, 24 and to the atmosphere through the gaps between the flanges 17 and between the flanges 18. The ends of the strip 32 are welded to straps, one of which has fingers 36, 37, Fig. 5, mounted on a pin 49, and the other has a portion 38 mounted on a pin 46, each pin 46 and 49 being carried by a slide 42 or 43 of inverted channel cross-section. A piston 52 of a ram 50 may be forced to the right against the action of a spring 57 by the pressure of air bled from the compressor through a conduit 53 fitted with a control valve 55. A lever 56 controls the pressure exerted on the piston 52 and thereby the extent to which the latter is forced to the right, which movement causes the piston-rod 60 to operate through linkages 65 to 68, Fig. 5, to force the two slides apart and thereby draw-in the strip 32 around the compressor casing 14. Thus the strip 32 may assume any position between its fully opened position and the position (dotted lines in Fig. 2) at which it fully closes the apertured portion of the casing 14. The ram 50 may additionally effect movement of inlet guide vanes of a highpressure compressor (not shown), or the guide vanes may be independently operated by means acting in synchronism with the ram. Specification 903,236 also is referred to.
