Title: Multi-feed circular knitting machine having a patterning mechanism
IPC: D04B15/68
Filed: 1971-06-28
Abstract: 1357916 Knitting-machines STIBBE MACHINERY Ltd 16 June 1972 [28 June 1971] 30139/71 Heading D1C A circular multifeed knitting machine comprises a pattern unit at each feed each unit being formed of a stack of pattern discs 29 having a circumferential series of frangible teeth positioned to act on reading butts 16 of tilting presser jacks 15 wherein the discs of alternate units are at a higher level than those of intermediate units so that the peripheries of the discs of adjacent stacks are interleaved. As shown in Fig. 5 the butts 16, 16' on alternate jacks may be at different heights so that for example the butts 16' are acted on by the lowest discs of each unit and the butts 16 by the next lowest disc on each unit. Alternatively all the butts 16 may be at the same height. As shown in Fig. 1 the needle 3 is acted on by a tilting jack 12 having a butt 25 which may be placed in a cam track b. The tilting movement is produced by the forked end 23 of a further tilting jack 21 which is in the same trick as and is acted on by the tilting jack 15. The jack 15 is located in its vertical position so that it reads a particular pattern disc by teeth 17 thereon which engage with teeth 18a on a ring 18 fixed to the needle cylinder. When it is desired to change the height of the reading butts 16 a cam surface 36 strikes a butt 19a on a member, 19 located in the same trick as the jack 15 to move the teeth 18a, 17 out of engagement. Then cams 44, 45, or 46 act on further butts 20 on the jack 15 to raise or lower it by a predetermined amount to read the next pair of pattern discs. When the lifting movement has taken place a cam surface 43a acting again on the butts 20 causes the teeth 18a, 17 to reengage thus fixing the jack 15 at its new level.

Title: Improvements in or relating to automatic switches for use in telephone systems
IPC: H04Q3/00
Filed: 1935-11-01
Abstract: 465,132. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd. Nov. 1, 1935, No. 30211. Convention date, Dec. 31, 1934. [Class 40 (iv)] The circuits of some connectors are such that a subscriber on finding a line busy may, by releasing the connection, dialling the number of the preceding line and then sending an impulse at a precise moment during the operation of the switching relay, cause the rotary magnet to take a step while the switching relay remains held. This possibility is avoided, according to the invention, by arranging that the additional impulse causes current flow in the holding winding of the relay in the opposite direction to the normal flow, thereby releasing the relay. In the known bi-directional connector C, the switching relay 9 pulls up its light contact 29 to close the locking circuit before its other contacts including contact 31 in the circuit of rotary magnet 11 so that it is possible for an additional impulse to be sent to the magnet. In the modified connector C', the operating circuit for 91 from ground on the third wire over its upper winding to battery on the cut-off relay 40 is the same as before but when 9<1> closes the light contact 29<1>, a series aiding circuit is closed over the lower winding and rotary magnet 11<1>. If at this moment an impulse (by switch-hook) delivered to the rotary magnet it passes also over the lower winding of relay 9<1> to battery on the cut-off relay 40, the windings now being in parallel and opposition so that 9<1> relapses and completes the circuit of test relay 7<1> which operates to the busy line and returns busy tone as usual.

Abstract: 433,406. Type - setting machines. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(International Business Machines Corporation ; 270, Broadway, New York, U.S.A.) Oct. 22, 1934, No. 30254. [Class 100 (iii)] A type storing and inserting mechanism for printing-machines comprises a carrier having a plurality of parallel guideways in which are slidably supported type-bars, and which is adapted to be moved to bring any selected plurality of guideways with their type-bars into operative position relatively to the printing-machine, so that the typebars can be projected endwise from the guideways in the direction in which these guideways extend. The invention is described with reference to the ticket-printing machine of Specification 423,133, in which type-bars are employed to print data which is frequently changed in two rows upon a ticket. The type-bars 12 are formed by channel members in which are arranged at suitable points single type maintained in position by tongues formed on the sides of the channel members and by strips extending longitudinally of the type-bars and engaging in recesses in the types. Alternatively, interchangeable set type locked in a holder, plates, slugs, &c., may replace the type-bars. The bars 12 are retained in guideways 31 formed in a rotary drum 22 mounted on a shaft 23, and adapted to be rotated by a hand wheel 35, provided with indicia corresponding to the different type-bars in the slots 31, and with notches which can be engaged by a spring 36 to lock the drum in its adjusted position. The type-bars are normally retained in the drum by flanges 32, 33 provided on the closed end plates 30, but any desired type-bars can be ejected from the drum into printing position in the printing-machine 10 by first setting the drum so that the bars to be ejected are opposite openings 34 in one of the end plates 30, which are in alignment with corresponding openings 15 in the printing mechanism. As described, two type-bars are projected simultaneously, but the device may be modified to move more than two type-bars into printing position, while single type-bars may be projected by not loading certain of the slots 30. The movement is brought about by two spring-pressed fingers 38 operated by a common handle 43 which may be pressed into engagement with recesses 39 in the type-bars ; the fingers 38 are carried by blocks 40 slidably mounted in slots 41 on the outer casing 27 for the drum so that when pressed into engagement with the type-bars, the fingers may be moved to eject partially these type-bars and thereby bring them into printing position in the mechanism 10. The part 47 of the casing 27 which supports the sliding blocks 40 may be hinged so that type-bars may be added to or removed from the drum 22.

Title: Process for the production of water-soluble polymers
Inventor: POHLEMANN HEINZ
IPC: B01J20/22
Filed: 1960-09-02
Abstract: Water-soluble polymers are made by polymerizing in aqueous solution one or more unsaturated compounds which individually or together are water-soluble and form water-soluble polymers, and then on to the resultant active polymer which has not been removed from its polymerization medium there are polymerized 0,5 to 30% by weight of the primary polymer of one or more unsaturated compounds which contain sulphonic acid and/or phosphonic acid radicals or radicals which yield sulphonic and/or phosphonic radicals after hydrolysis, until the second polymer formed has a K-value of at least 100 and wherein the quantity and nature of the monomers added to the primary polymer are such that the resulting product is water-soluble or water-solubilizable by hydrolysis.  Monomers specified for use in forming the primary polymer are acrylic and methacrylic acids and their salts and amides, acrylic esters, acrylonitrile, vinyl pyrrolidone, styrene, vinyl methyl ketone, vinyl chloride and vinyl esters.  Monomers specified containing sulphonic and phosphonic radicals are vinyl sulphonic acid, styrene monosulphonic and disulphonic acids, vinyl naphthalene sulphonic acid, vinylimidazole and vinylbenzimidazole sulphonic acids, reaction products of acrylyl or methacrylyl chloride with aminoalkylene sulphonic acids, cyanuric acid derivatives containing sulphonic acid groups and an acrylamide group, and corresponding compounds containing phosphonic acid radicals.  The sulphonic or phosphonic acids may be used in the form of their salts or their esters or amides which are saponified after polymerization.  Polymerization may be initiated by compounds such as azo-diisobutyramide, hydrogen peroxide and persulphates which may be activated with sulphites, hyposulphites, amines, ascorbic acid, cobaltous salts and ferrous salts.  The examples describe processes in which: (1) acrylamide is polymerized in aqueous solution with the acid of potassium persulphate and formaldehyde sulphoxylate, followed by the polymerization in the same medium of sodium vinyl sulphonate; and (2) acrylamide is polymerized in aqueous solution with the aid of hydrogen peroxide and sodium sulphite, followed by the polymerization in the same medium of diethyl vinyl phosphonate with the subsequent hydrolysis of the product by heating in the aqueous medium.

Title: Improvements in and relating to speed indicators and the like instruments
IPC: G01P3/48
Filed: 1922-11-06
Abstract: 210,854. Cox, A. M. Nov. 6, 1922. Impulse and momentum speed indicators; transmission mechanism; registering distance upon counters. -The instrument is actuated by a pawl-and-ratchet mechanism in which the pawl is given its inoperative stroke by an electromagnet periodically energized by a current generated by a device secured to the wheel or the shaft of which the speed it to be measured, the driving stroke being given by a return spring. An armature 6 is mounted on a pivot 7 between the pole-pieces 4, 5 of the electromagnet 3 and is normally held away from the pole-pieces by a spring 10, a stop 9 limiting its movement. An arm 8, Fig. 4, secured to the armature carries a spring-controlled pawl 11 engaging a ratchet wheel 12 on the spindle of an inertia wheel 13, this spindle also carrying a pinion 14 meshing with a toothed wheel 15 controlled by a recoil spring 16. The spindle of the wheel 15 is provided with a pinion 16 meshing with another pinion that is connected through a hair spring 20 to the pointer 21 of the instrument. A balance wheel 22 damps the action of the hair spring. When the magnet is energized the armature and the arm 8 are rocked, the pawl 11 being brought up to the ratchet; on de-energizing the spring 10 swings the armature and its associated parts back again, the pawl then driving the ratchet until the movement of the armature lifts it clear. To adjust the speed indicator for different vehicles the flexion cf the spring 10 may be altered by moving a pivoted bar 50 through a hole in which the spring is passed. The arm 8 carries a pawl 30 engaging a ratch wheel 31 connected to a worm shaft 35 actuating an odometer train provided with trip and total registers 37, 38. To zeroize the trip register, a plunger 42 moves a lever 43 to lift the form from engagement with its worm-wheel, a spring 46 then returning the indicator to zero. The periodic electric impulses actuating the device are given either by a contactbreaker mounted on the shaft and connected up to a source of steady current, or as described in Specification 211,086 by securing a broken magnetic ring to a wheel and mounting adjacent thereto a bobbin-system of any suitable kind to generate current when the break in the ring passes.

Abstract: 1493915 Expanding pulley gear HEBERLEIN MASCHINENFABRIK AG 21 July 1976 [28 July 1975] 30318/76 Heading F2D A pulley 4 driven by a motor 8 and connected by a V-belt 7 with a spring-loaded pulley 1 has a side plate 6 fixed to the motor shaft 9 and an axially adjustable side plate 5 engaged, through a thrust bearing 10, by a non-rotatable, hollow, cylindrical member 17. A non-rotatable cylinder 16 held against axial movement by a connection 13 with a bearing 12 on an extension 11 of the motor shaft contains a piston 27 movable between stops 30, 31 and having a rod 29 held against rotation by a pin 18 and terminating in a threaded pin 20 on which is screwed an adjustable abutment ring 21 with a scale coacting with a pointer 22 for setting the transmission ratio. After the motor is started, with the apparatus set as shown for driving the pulley 1 at its -slowest speed, a valve, not shown, is automatically actuated to supply pneumatic or hydraulic pressure fluid to a connection 24 to cause leftward movement of the piston which initially takes up the lost motion between the ring 21 and the end of the member 17 and thereafter displaces the latter whereby the adjustment imparted to the pulley side plate 5 is equal to the difference between the total movement of the piston between its stops 31, 30 and the distance travelled by the ring 21 before it abuts the end of the member 17. When the motor is stopped, or in the event of current failure, the valve is reversed to pressurize a connection 23 and return the piston to its starting position. The speed of the piston may be controlled, e.g. by a throttle, and may be different in each direction. The ring 21 may be adjusted when the motor is either stationary or running. Electromagnetic motor means may take the place of the fluid-actuated piston 27.
