Title: Feed-control device for textile drawing apparatus
Inventor: MCANGUS ELI HUGH
IPC: D01H5/40
Filed: 1956-02-13
Abstract: 802,585. Drawing frames. WEST POINT MANUFACTURING CO. Feb. 13, 1956, No. 4424/56. Classes 120(1) and 120(2) A sliver feed control arrangement for drawing apparatus consists of means for measuring the amount of material passing a feed roller and connected to pulleys movable in response to changes in the material thickness, a cable passing alternately over the movable pulleys and over fixed pulleys and being connected to a speed regulating device. A non-linear correcting device is interposed in the cable transmission. Each sliver 5 fed to the apparatus passes into the groove of a roller 82 and is compressed therein by a follower roller mounted on a pivoted arm 108 that carries a pulley 118 at its outer end. Each arm 108 is spring- loaded to maintain pressure on the slivers. A length of flexible cable 134 passes alternately over the pulleys 118 and over fixed pulleys. One end of the cable is looped upon itself and the other end is weighted. Rocking the arms 108 according to variations in sliver thickness results in cable movements by which a change speed device 100 is controlled. The device 100 receives motion through gearing from a motor 36 and transmits drive to the rollers 82 through a shaft 98, chain 96 and a shaft 84. Because of a non-linear function between sliver thickness and feed roller speeds, a correcting device is provided. This may take up the form of an eccentrically slotted disc rotated by the cable and with which a lever co-operates that controls the change speed device 100, or the cable may be divided with an eccentric segment interposed. Specifications 6588/05, 26702/07, 26703/07 [all in Class 120] and 744, 399 are referred to.

Filed: 1937-02-15
Abstract: 490,394. Hydraulic transmission of power. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M., [Firm of]). Feb. 15, 1937, No. 4560. Convention date, Feb. 20, 1936. [Class 69 (ii)] A turbo-coupling of the F÷ttinger type is, for filling and emptying, that is for putting into and out of operation the working circuit, provided with two stationary oppositely-directed scoop tubes which are so positioned as to be out of the path of the liquid vortex circulating between the impeller and runner but to be capable of engaging liquid contained within a rotating part of the coupling. The scoop tubes a, b, Figs. l, 2 project into a chamber c<4> formed by shells c<2>, c<3> secured to the impeller c ; for filling, the control valve e is moved to the left, and liquid from the reservoir f is drawn into the chamber c4 through the scoop tube b; this liquid is picked up by the scoop tube a and passes into tube a<1> which is shut off from the reservoir, the liquid passing through tube g and non-return valve g<1> into the working circuit. The valve e is then moved to its central position, cutting off the tubes b<1>. a<1> from the reservoir.f; some liquid passes from the working circuit through ports m in the shell c<2> into the chamber c<4> whence it is removed by the scoop tube a and returned through the valve g<1> into the working circuit. To empty the coupling, the valve e is moved to the right, the tube a' being thus put into communication with, and the tube b<1> out of communication with, the reservoir. In a modification, the scoop tubes are combined into a single U-tube provided with a port at its lowest part. When the coupling is one adapted to run in either direction of rotation, the branch duct g and non-return valve g<1> are duplicated. In a modification, Fig. 4, control is effected by a displacer i dipping adjustably into the reservoir and regulating the delivery to the suction tube b<1>; an adjustable valve l is provided in the discharge tube a<1>. Alternatively, the suction tube may be vertically adjustable or flexible so that its depth of immersion can be varied. The control, whether by valve, displacer or adjustable tube, may be effected by hand or by a speed-responsive device or by other automatic regulating means.

Title: Apparatus for wrapping small articles
IPC: B65B11/54
Filed: 1971-02-19
Abstract: 1378163 Wrapping machines W S ROBINSON 9 Feb 1972 [19 Feb 1971] 4973/71 Heading B8C Apparatus for wrapping articles comprises a wrapping unit, an article delivery station and means for effecting relative movement therebetween, said wrapping unit including means for collecting an article from said delivery station, means for drawing wrapping material from a supply thereof both said means being mounted on a common movable support movement of which transports said wrapping material and said article to a wrapping position preparatory to wrapping of the material around the article. As shown, sweets to be wrapped are placed one in each of apertures 36 of four carriers 13. The carriers are rotated stepwise through gearing from a drive shaft 22 as a carrier frame 14 is reciprocated between the carriers 13, by a cam wheel 19. The carrier frame 14 supports four wrapping assemblies 15 each of which is associated with a carrier 13 and each of which is operated by sprockets 42 driven by chains 40 from drive shafts 38. Each assembly 15 is releasably mounted on the frame 14 and comprises a pair of cam-operated spring loaded sweet gripping arms 48 and a pair of papergripping arms 59 which co-operate with a pair of fixed plates 60 whereby paper 62 supplied through a feed device 63 enters slots 61 and is gripped between the arms 59 and plates 60. A stud 65 prevents operation of the arms 59 when no sweet is present at the respective carrier 13. A wrapping device 66 co-operates with a pusher member 67, adapted to be moved upwardly during the operating cycle, by a cam controlled linkage driven from the shaft 38, whereby the member 67 pushes each sweet and its wrapper paper through the device 66 and into engagement with gripping arms 70, whereafter a folding member (not shown) forms a first tuck beneath the sweet. As the assembly 15 then moves away from the carrier 13, the arms 70 are drawn over a fixed plate 76 which folds the paper to form a second truck. A peg 77 raises each sweet out of its aperture at carrier 13. A cutter assembly 79 severs the wrapping paper as each sweet is positioned below the wrapping device 66. The apparatus is driven by a single motor 11 and the arrangement is such that as the wrapping assemblies 15 at one end of the machine move towards their respective carriers 13, the assemblies 15 at the other end of the machine move away from their respective carriers and perform the wrapping operations at that end of the machine. The apparatus may be modified to include more than 4 carriers and wrapping assemblies, and the articles may be hardwrapped. Also, the wrapping paper may be presented below the articles.
Patent GB-671731-A (GB)
Title: Improvements in the production of ketones and acids
Inventor: REPPE WALTER
IPC: C07C51/14
Filed: 1950-02-28
Abstract: Aliphatic ketones and keto-carboxylic acids are prepared by reacting carbon monoxide and water with acetylenes at elevated temperature and under increased pressure in the presence of a complex cyanide of a metal capable of forming metal carbonyls or in the presence of a mixture of compounds capable of combining with each other to form such a complex cyanide.  Preferably the temperature of the reaction is in the range 60-200 DEG  C. and the pressure in the range 10 to 40 atmos.  Solvents such as organic oxygen-containing solvents miscible with water, e.g. ethers or ketones, or saturated hydrocarbons may be used.  The gases may be diluted with nitrogen or methane.  Technical gases such as water-gas, generator gas or electric arc acetylene may be used instead of pure gases.  Polyketones or polyketo carboxylic acids are formed and also in some cases monoketones, mono- and dicarboxylic acids and esters.  Suitable catalysts are, for example, complex cyanides of nickel such as K2[NiCy3] or K2[NiCy4], complex cyanide containing in the cation metals such as sodium, lithium, calcium, barium, magnesium, zinc, cadmium or mercury or containing in the cation the ammonium radical or the radical of an organic amine. The catalyst may be used in solution or suspension or applied to a carrier, e.g. aluminium oxide, silicic acid gel or pumice stone.  The most suitable starting materials are the hydrocarbons of the acetylene series, e.g. methyl-, isopropyl-, vinyl- and divinyl-acetylene, phenyl- and diacetylene.  Acetylenes containing substituents, e.g. propargyl alcohol, butinol, butinediol, hexainediol, amino di-propines and -butines and carboxylic acids of the acetylene series may also be used.  In the example acetylene, water and carbon monoxide are reacted together in the presence of potassium nickel cyanide at elevated temperature and pressure to give polyketo carboxylic acids and small amounts of ketones.
