Title: Device for joining a new web of sheet material wound on a reel to a moving web which is being delivered from a feed reel
IPC: B65H19/18
Filed: 1966-04-06
Abstract: 1,141,163. Feeding webs. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 6 April, 1966 [9 April, 1965], No. 15259/66. Heading B6B. In web-roll changing apparatus, the leading end of the replacement web is held against a roller 9 by a pressure roller 12. When the running web-roll nears exhaustion, the pivoted surface brake (38, Fig. 1) operates a microswitch (42) to commence the splicing operations. Roller 9 is driven via a free-wheel coupling in the direction of the arrow f to advance the replacement web up a guide passage 35 to the nip formed between a knurled splicing roller 16 and a plastic-covered backing roller 18. When the new and old webs are superimposed, the nip pressure is increased by an electromagnet 21 to cause the webs to splice. Prior to this, the old web was severed by an electromagnetically operated knife 25 and stationary blade 29. When the splicing operation is completed, the nip pressure of the splicing rollers is reduced, the drive to roller 9 ceases allowing the roller 9 to free wheel and act as a guiding roller, the knife 25 is pivoted on its mounting plate 23 to co-operate with stationary blade 30, and when the leading end of a new web is threaded over guide roller 44, it is held against roller 10 by moving the pressure roller 12 on its pivoted mounting 11 into engagement therewith. A visual indicator (67, Fig. 7) is energized until the exhausted web-roll is replaced, and remains energized if the operator forgets to engage the web-roll surface brake (38 or 39, Fig. 1). If the visual indicator remains energized, the web from the running web-roll will continue to be advanced to the machine being fed, until the splicing operation is imminent, whereupon the machine is shut-off.

Title: Method of stacking and storing flat objects
IPC: B65H29/24
Filed: 1978-04-18
Abstract: Apparatus for stacking and storing a plurality of flat objects, such as letters. The apparatus includes at least one storage box and a loading device designed to transport the flat objects from a source and to project them into the interior of the box. The box and loading device are respectively positioned so that the flat objects are projected into the box at an incline with respect to its bottom and a portion of each object's leading edge impacts a stopping surface formed in one of the side walls of the box. This impact imparts a rotational couple to the object which brings the lower edge of the object into firm engagement with the box bottom. The object is then moved onto the stack of similar objects being formed in the box, either by gravity or an auxiliary device. In one preferred embodiment, relative movement is provided between the box and loading device so that the objects can be projected into the box at a point close to the top of the stack. Other embodiments provide for automatic feed of boxes past the loading device so that loading can be performed continuously.

In the embodiment described the unit also comprises a coin operated ticket dispenser 9, the tickets 17 dispensed being passed directly to the cancelling device 11 by means of a reciprocating plate 18 and the conveyer belt 21, the driving motor 24 of which is switched on by the leading edge of the ticket engaging lever 25 and operating microswitch 26. The cancellation device comprises a fixed printing block 27 and a ram 28 connected to a solenoid 29 (see also Figs. 3 and 4, not shown). The printing block carries a column of figures corresponding to the fares, a machine number, and manually adjustable fare stage printing wheels 30. The ram has a pair of cutting blades (36) with a spacing slightly greater than the width of the block 27 and six pairs of apertures (35) through which pass stops 42. The leading pair of stops are urged downwardly and the other stops urged upwardly by springs and each pair of stops is connected to a corresponding pair of solenoids 39a-39f. The stops when lowered contact the forward end of the ticket adjacent each longitudinal edge. The operation of the push-button 38a corresponding to the lowest fare energizes the solenoid 29 immediately provided that the trailing end of the ticket is in contact with microswitches 20, lowering the ram 28 to sever a portion of length proportional to the fare from each side of the ticket. After a delay the solenoids 39a are energized to raise the leading stops 42 and the ticket is delivered to an exit slot 47. When a push-button 38b-38f is depressed the solenoids 39a and the corresponding pair of solenoids 39b-39f are energized immediately, to raise the leading stops and lower another pair, and the solenoid 29 is energized after a delay. When a previously used ticket is inserted through slot 43 the driving motor 24 is energized through lever 45 and microswitch 46 to deliver the ticket to the cancellation device. The stops 42 then engage the ends of the recesses formed in the ticket during the previous cancellation. If the stops 42 depressed correspond to a greater value than the remaining credit of the ticket, the ticket will be stopped in such a position that microswitches 20 are not operated and the circuit to solenoid 29 will be diverted to a buzzer.

Title: Improvements in or relating to straight bar knitting machines
Inventor: START ERNEST
IPC: D04B11/00
Filed: 1952-06-23
Abstract: 743,330. Knitting-machines. COTTON, Ltd., W. April 23, 1953 [June 23, 1952], No. 15769/52. Class 74 (2). Sinker jack control means automatically and positively locates the jacks in one intermediate retracted position substantially in contact with the jack sinkers before re-advancement and substantially uniformly accelerates the jacks, and consequently the jack sinkers, therefrom. Jack springs 14 are carried on a rockshaft and can thus be positioned, through truck arm 16 and truck 18, in accordance with a high point B on a knitting cam 19, a low point C on a fashioning cam 30, or an intermediate level A provided on both and by reason of which the truck 18 can be shogged from one cam to the other. When the jack sinkers 1 have been advanced by the action of the slurcocks 8 on the jacks 4, the truck 18 rides on to the level B of cam 19, to maintain the heads 6 of the jacks in contact with the rear edges 25 of the jack sinkers, the bent free ends 13 of the jack springs 14 engaging the lower face of an abutment 10 on the tails 7 of the jacks. Immediately before the catch bar retracts the jack sinkers, the jack springs are rocked rearwardly by the action of gravity when the truck 18 is on level A of the cam 19, to such an extent that the subsequent rearward rocking of the jacks brings the abutments 10 clear of the jack springs which now engage the faces 11 of upper abutments 9 on the jack tails and so temporarily locate the heads 6 of the jacks in contact, or nearly in contact, with the rear, edges 25 of the jack sinkers. For loop transfer the truck 18 rides on to the low part C of the fashioning cam 30. The jack sinkers can thus be fully retracted and the jacks engage a fixed backstop 26. At the end of the fashioning cycle, the jack sinkers are left by the catchbar in their intermediate position, ready for the next advance by the slurcock; and the truck 18 is brought on to the level A of cam 19 to advance the jacks substantially up to the jack sinkers. Thus the jack heads 6 are maintained always near to or in contact with the rear edges of the jack sinkers during the drawing of each knitted course. The jacks engage a slightly inclined lead-in to the concave parts 21, 22 of the slurcock by which they are substantially uniformly accelerated. Any jacks not correctly located in the intermediate position by their jack springs will be advanced initially by the parts 23 or 24 of the slurcock. The cam-controlled jack springs and cooperating jack abutments may be replaced by a suitably operated extension of the catch bar, or by separate catch bar mechanism.

Title: Pumping unit
IPC: H02K5/128
Filed: 1961-05-03
Abstract: 977,144. Electric motors. E. HANENSTEIN. May 3, 1961 [May 3, 1960], No. 16059/61. Heading H2A. In a pumping unit comprising a centrifugal pump and an electric motor with the impeller of the pump and the rotor of the motor arranged in intercommunicating spaces, the slots in the stator core are closed on the surface facing the air-gap between the stator and rotor and that surface and the corresponding surface of the rotor are provided with a coating resistant to acids and bases. The pump comprises inlet and outlet openings 12, 13 and an impeller 16 mounted on an axial shaft common to the pump and motor. The rotor is of upwardly-open bell shape and is of squirrel-cage type comprising totally enclosed vertical aluminium rods 37 interconnected by end discs 38, the magnet iron being totally surrounded by a metal part 39 which is secured to the axial shaft. The stator surrounds the rotor and comprises two annular sets of laminations 21, 22, the inner set 21 being held in place between fixed portions of the motor housing by rings 23, 24. This set is provided with slots which open outwardly and in which the stator windings 31 are housed. The outer set 22 are secured by a sleeve-like casing of the motor, this being bolted to a carrier frame 10 and to an upper bearing sleeve 26. The bearing sleeve 26 is provided with an annular cavity 45 through which cooling liquid flows. The unit is designed for use with corrosive liquids and all exposed parts, except those of the stator and rotor, are made of resistant materials. In order to protect the stator and rotor they are provided with respective enamel coatings 61, 62; the enamel may if desired include magnetizable material. In use the unit effects continuous circulation of a corrosive liquid such as an acid. The acid enters at 12 and leaves at 13. An external line is taken from the outlet side to an inlet tube 55 and through this a certain amount of liquid flows to serve both as lubricant and coolant. Some of this liquid passes between bearing surfaces 47, 50 and some passes through the end bearing 48, 51 into a space enclosed by the cover 54. This latter liquid then flows through duct 56 into the space between bearings 47, 50 and conical bearings 58, 59 and passing through the latter arrives at the space enclosed by the bell-like rotor. The projection 43 prevents liquid from passing directly over the top surface of the rotor; however, some evaporates to cool the rotor and then condenses on the lower projecting surface of the cooled bearing sleeve 26 and is thrown thence into the air-gap between the stator and rotor. Since this liquid is recondensed vapour it is free from foreign matter, and no choking of the air-gap can occur. The liquid then collects on the partition between pump and motor from which an outlet 60 leads back to the reservoir through which the liquid is being circulated. A further series of passages 41 pass through the rotor and allow any excess liquid to drain off and be ejected into the pump space through the centrifugal delivery arrangement 65.
