Title: Improvements in or relating to an automatic fastener setting machine
IPC: A41H37/04
Filed: 1966-01-25
Abstract: 1,082,449. Attaching fasteners to garments. SCOVILL MANUFACTURING CO. Jan. 25, 1966 [Feb. 17, 1965], No. 3372/66. Heading A3H. A machine for setting a plurality of fasteners to a garment comprises a machine head and means including a reciprocable cam co-operable therewith at a setting station to set a fastener when the ram descends, a one revolution clutch arranged to operate the ram through one complete cycle each time the clutch is actuated and means for gripping and feeding the garment forward automatically and means responsive to movement to actuate the clutch. A pedestal 6 supports a setting machine having a ram 8 with a die co-operating with a die on a post 9 beneath a garment C on a plate 16. The ram is operated by a drive belt 10, a pulley 11, a drive shaft 12 and a one revolution clutch 13 under control of a solenoid S1. At one end of the shaft 12, a cam 15 controls three switches. The setting machine supports a track for guiding the T-shaped base on a garment feed carriage 23 secured to a drive chain 29. The carriage has fixed and movable garment clamping jaws 30, 31 controlled by a solenoid S3 on the carriage. The carriage chain 29 is indirectly driven by a reversible motor M2 through a clutch which is engaged when a solenoid CI is energized. The carriage operates a cut out when it reaches its starting station. The carriage is arrested along the track by a series of pins 41 on the track operating a switch LS1 on the carriage. The carriage switch LS2 is operated by an end stop 46 on the track. Initially the jaw 31 is held open by solenoid S3, the ram motor clutch 13 is inoperative and the brake for the carriage is released by solenoid S2. A foot switch is depressed to energize the solenoid S3 so that the jaw 31 clamps the garment and the clutch solenoid S1 is energized. The main shaft 12 makes one complete revolution to operate the ram down and up and set a fastener. The cam 15 rotates and operates a forward relay, the solenoid CI energizes to actuate the clutch to drive the carriage motor M2 to advance the garment to the next setting position where switch LS1 is closed by a pin 41 and activates a relay which de-energizes the solenoid S2 to apply the brake, de-energizes the solenoid C1 to release the clutch and disconnect the drive from the carriage motor, it maintains the grip by the jaw 31 on the garment and energizes the solenoid S1 to actuate the ram clutch and recommence the cycle. When the carriage reaches the end of the track the reversing switch LS2 is closed by the stop 46 and the carriage returns to its starting station. The solenoid S3 is energized to open the jaw 31 and release the garment. Another garment is inserted and the cycle recommences by pressing the foot switch.

Title: Process for the optical brightening of polymeric or copolymeric acrylonitrile fibres
IPC: C07D263/62
Filed: 1965-01-26
Abstract: Polymeric or copolymeric acrylonitrile fibres are brightened by treating them with an aqueous solution containing a compound having the formula <FORM:1044436/D1-D2/1> in which R1 and R11 are alkyl groups having not more than 5 carbon atoms, R1 and R2 are unsubstituted or non-ionogenically substituted straight chain alkyl groups having not more than 5 carbon atoms, Y is hydrogen or chlorine, X is a colourless anion and n is the valency of the anion X.  When R1 and R2 are non-ionogenically substituted alkyl groups these may be b -cyanoethyl or b -chloroethyl groups.  X may be C1-, Br-, aryl-So3 - or HSO3-.  The brightening agents may be applied to the fibres from aqueous acid solutions, the acid present being acetic, oxalic, formic, hydrochloric, sulphuric, benzene sulphonic or p-toluene sulphonic acid, and the solution optionally containing a detergent e.g. a non-ionogenic substance such as a fatty alcohol polyglycol ether or nonyl phenol polyglycol ether, sodium metabisulphite, sodium tetrametaphosphate and sodium hexametaphosphate.  Alternatively the fibres may be impregnated with an aqueous solution of the brightening agent which may also contain surface active dispersing agents in a foulard and then subjected to a hot wet treatment by passing them through hot aqueous acid such as hot formic acid or by steaming.  The fibres may subsequently be treated with bis-stearyl-bis-methyl ammonium chloride.  The copolymeric acrylonitrile fibres treated may comprise 80-99% by weight of acrylonitrile and 20-1% by weight of a copolymerizable compound, e.g. vinyl pyridine, vinyl acetate, vinyl chloride, N-vinyl carbazole, styrene, vinylidene chloride or an acrylic acid ester.

Title: A method of cooling reactors for the hydrogenation of carbon monoxide
IPC: C07C29/152
Filed: 1950-02-10
Abstract: In the catalytic hydrogenation of carbon monoxide wherein the synthesis gas is passed downwardly through a substantially vertical layer or column of the catalyst; a positive temperature gradient rising in the direction of gas flow is maintained by employing as an indirect cooling liquid a solution having a solvent component which is a single liquid compound or an azeotropic mixture and which vaporises under the conditions within the reactor, the solution being such that its boiling point varies with relatively small changes in the concentration of the solution so that the boiling point of the lower layers of the solution is from 5 DEG C to 20 DEG C higher than the boiling point of the upper layers of the solution.  Solvent vaporized off is replaced by fresh solvent introduced at the top of the cooling space. Suitable solutions are aqueous solutions of salt, calcium chloride, magnesium chloride or sodium hydroxide.

Title: Improvements in shock-absorbers for motor and like vehicles
IPC: F16F7/04
Filed: 1930-02-01
Abstract: 341,731. Frictional vibration-dampers. SOC. ANON DES ETABLISSEMENTS REPUSSEAU ET CIE, 75, Rue Danton, Levallois-Perret, Seine, France. Feb. 1, 1930, No. 3531. Convention date, Feb. 9, 1929. [Class 108 (iii).] In vehicle vibration-dampers in which several arms are pivoted together in such a way that the different frictional elements come into operation in succession one of the friction elements is operated from an arm through an elastic device consisting of two concentric metallic sleeves having a rubber or similar ring between them. The two main arms 1, 2 are connected respectively to the frame and axle of a vehicle and are pivoted together by the centre pin 9, by which pressure is applied to a number of metal discs alternating with discs 7, 7a, 8, 8a of frictional material. The two outer discs 6, 6a are integral with the arm 1 while the two intermediate discs 5, 5a are similarly integral with the arm 2. The central disc 12 is however operated from the arm 1 through an elastic device which includes the rubber sleeve 16 interposed between an outer sleeve 14 and an inner sleeve 15 bolted to the arm 1. Relative angular movements of the arms 1, 2 thus always brings the outer frictional elements 8, 8a into action, but the inner frictional elements 7, 7a do not impose any frictional resistance at first owing to yielding of the rubber ring 16.

Transducer. Fig. 1.-Glass plate 2 supports vaporized-on interdigital transducer 5 on that surface adjacent the gap of liquid 3. Piezoceramic or bismuth germanium oxide piezo body 1 is polarized in a direction parallel to the transducer fingers, and the Bleustein wave is generated in the body 1 since the electric field from transducer 5 readily crosses the liquid 3 in view of its high dielectric constant. The bismuth germanium oxide body is cut in the (110) plane, with propagation in the (110) direction. The fingers of each comb of the transducer are spaced by an acoustic wavelength. Variable delay line, Fig. 2.-Piezoelectric body 11, polarized parallel to the fingers of vaporized-on transducer 5, is separated by liquid (3), Fig. 3 (not shown), from a second piezoelectric body 22 supporting output transducer 6. The liquid may be retained by spacer ledges 4, or, utilizing the capillarity of the liquid to ensure separation of the bodies, the ledges may be omitted. Delay time is varied by relative longitudinal displacement of bodies 11, 22, coupling between them being purely by electric fields passing via liquid (3), acting also as a lubricant. Dimensions, frequency, bandwidth, and delay times, are given. Travelling wave amplifier, Fig. 4.-Semiconductor body 222, in which a drift field is set up between metallized areas 7, is coupled via liquid 3 to piezoelectric body 111, causing amplification of the Bleustein wave passing from transducer 5 to transducer 6.
