Title: Improvements in printing machines
IPC: B41F13/00
Filed: 1959-05-06
Abstract: 878,899. Printing-machines. GERICKE, E. May 6, 1959 [Oct. 31, 1958], No. 15515/59. Class 100(2) [Also in Group XXIV] A lithographic printing machine, particularly a rotary offset printing machine, in which the input shaft of the machine can be coupled by a dog clutch either to a power drive or a manual drive is characterized in that a slip coupling is interposed between a driven pulley and the input shaft of the machine. As shown, the input shaft 5, Fig. 3, is driven by a pulley 4 housing a friction clutch comprising friction liners 6, 6a, urged together by springs 7 on adjustable screws 8 to engage a coupling disc 3 having teeth engageable with teeth 23 on a slidable clutch member 2 keyed to the shaft 5 by a key 22 as shown in Fig. 4. In this position, the pulley 4 is operatively connected to the shaft 5 for power drive. The member 2 is moved towards pulley 4 by a sleeve 19, Fig. 4, rotatably mounted on shaft 5, the sleeve 19 being moved towards the pulley 4 by a cap 1 of a hand crank 9 and in the opposite direction by a spring 10. The sleeve 19 is retained in its right hand position by a locking lever 21 engaging a step 25 on sleeve 19, the sleeve 19 being released upon a 45 degrees rotation of the hand crank 9, thereby causing spring 10 to press member 2, sleeve 19, and cap 1 outwardly until the lever 21 engages a middle step 26. The teeth on the disc 3 and member 2 are disengaged in this position to stop the machine, while the pulley continues to be driven. Upon 90 degrees further rotation of the crank 9 the lever 21 is released from step 26, thereby causing spring 10 to push member 2 further outwards until teeth 24 thereon engage teeth 27 on the crank 9 for transmitting manual drive.

Title: Improvements relating to centrifugal pumps
IPC: F04D1/12
Filed: 1937-06-04
Abstract: 493,333. Centrifugal pumps. BEAUMONT, E. G. E., and DOWLE, R. C. G. June 4, 1937, No. 15525. [Class 110 (i)] A centrifugal pump comprises a whirling chamber circulating fluid through an ejector to draw fluid from the source of supply, the chamber having collecting means for delivery of fluid. The whirling chamber consists of a bowl A fast on a spindle B driven by a motor C mounted on a chamber D. Fluid is collected from a point of high pressure by a scoop F and passed into chamber D whence it returns through ejector G which draws fluid from inlet H. A scoop J connected to the outlet is set with its lower end at a smaller radius from the axis of rotation than scoop F so that sufficient fluid is maintained in bowl A to immerse scoop F. Excess fluid either collects within casing E having drain outlet N or is drawn back to storage by a third scoop at a smaller radius than scoop J. To prevent excess fluid, the ejector may be set or shaped so as to have its flow checked by the fluid in bowl A, or this check may be effected by a spring arm moved by the fluid to obstruct the ejector. Additional scoops F, J and ejectors G may be used, and the scoops J may be placed at varying radii to give different delivery pressures. The axis of the bowl may be angular or horizontal, or the bowl may be inverted. The bowl A may have interior vanes or ribs.

Title: Method of heat-treating continuous products in fluidized beds, and apparatus for performing the same
IPC: C21D9/567
Filed: 1964-04-15
Abstract: <PICT:1045894/C6-C7/1> Continuous products are heat treated whilst passing through at least one fluidized bed whilst simultaneously undergoing physio-chemical reactions with the bed sustaining fluid. Metal strip 2 undergoes a hot oxido-reduction in fluidized beds 35 and 28 contained in refractory chambers 3, 4 respectively, then after passing through pressurized transfer chamber 7 undergoes controlled cooling in fluidized beds 44,45, contained in chambers 11, 12 prior to metallic coating by hot immersion. Combustible gas and oxidant in proportions to provide a reducing atmosphere are introduced into the bottom of chamber 4 through boxes and tubes 22, 24, 25 having porous end covers, ignite in stationary bed 27 and provide the reducing heat treating, bed sustaining fluid for fluidized bed 28 in which annealing or tempering may be performed. Excess oxidant to provide an oxidizing atmosphere is introduced at the top of bed 28 via porous refractory tubes 29, and the resultant oxidizing bed fluidizing gases pass through refractory tile 32 and stationary bed 34 to sustain the oxidizing fluidized bed 35 before passing out via discharge flue 39. A neutral gas is introduced in a similar manner to the base of chamber 11 to act as a sustaining fluid for beds 44, 45 in which the sheet is cooled, the heat released being transferred to hairpin tube clusters 46, 49 to generate steam.  The neutral gas may be recycled. In modifications electrical heating or radiant tubes together with the chemically active bed sustaining gas may be used in place of the combustion occurring within the fluidized bed and the fluidized bed particles may be active to the continuous product which, if in the form of wire or bar may travel in a horizontal path.  Alternatively fluidized beds may be used within which the product undergoes reversal of motion both entering and leaving through the upper surface of the beds.

Abstract: 1,180,984. Winding and reeling. CUTTERS MACHINE CO. Inc. 4 April, 1967 [29 April, 1966], No. 15610/67. Heading B3E. [Also in Division B8] An arrangement wherein a roll 15, Fig. 2, such as a cylindrical drum, or a wound roll of cloth, paper, foil or sheet metal, is supported on two spaced parallel rollers 11, 12, one at least of which has a high friction surface, has means for loading the roll on to the supports 11, 12 comprising a platform 45 with a low friction surface mounted between the supports and reciprocable vertically to move the roll into engagement with the supports. As applied to a machine for feeding cloth from a roll 15 to a webspreading machine as described in Specification 1,180,983, roll of cloth 15 on a core 16 rests on two rollers 11, 12 during operation of the machine. The rollers are driven to feed the material. Conical bearings 31, 41 for engaging the ends of the core 16 are carried by members 29, 39 freely slidable on frame members 27, 37. The member 27 is fixed but the member 37 is pivoted at 42 so that it can be moved away to insert a roll 15. Connected to the member 37 by a link 70 is a horizontally-movable slide 55. Mounted between the members 27, 37 for vertical movement only is the platform 45. The platform 45 is connected to the slide 55 by one or more links 62 so that as the member 37 is pivoted outwardly, the platform 45 rises until its upper surface is above the level of the rollers 11, 12, thus permitting the insertion of a roll by sliding it endwise along the platform 45. The member 37 is now moved back to its normal position, with the bearings 31, 41 engaging the core 16, thus causing the platform 45 to descend so that the roll rests on the rollers 11, 12 ready for feeding. A latch 35 holds the member 37 in operative position.

Patent GB-600085-A (GB)
Title: Improvements in or relating to electrically-driven web-winding equipment
IPC: B65H23/198
Filed: 1945-06-25
Abstract: 600,085. Automatic control systems for winding equipment. HAWKINS, C. G., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 25, 1945, No. 16179. [Class 38 (iv)] In web-winding equipment the power input to a motor driving a winding reel is maintained constant against progressively increasing torque and the speed maintained constant on removal of the load due, for example, to a break in the web. In the Figure, the armature of the winding motor 3 which drives reel 2 is supplied from lines 4, 5 and the separately excited field 3a is series connected with metadyne 8 across supply lines 6, 7. The field 8a of the metadyne is supplied from thermionic device 9 to which are applied voltages from the series field 3b and resistor 16. The input to component 9b of device 9 is dependent on the armature current of the winding-reel motor 3 which is maintained at a predetermined level through the action of device 9 on metadyne field 8a and hence on field 3a. As the winding diameter of reel 2 increases, the field of the motor 3 is strengthened to raise the torque progressively and to maintain constant the tension of the web 1. With a sudden rise in speed of motor 3, for example, due to breaking of web 1, the bridge formed by tachometer generator 10 and resistors 11, 12 and 16 is unbalanced and the resultant voltage unbalance across a part of resistor 16 is applied to component 9c and reacts on field 3a through metadyne 8 to limit the speed of motor 3. Under normal conditions of winding, the bridge is automatically maintained in a balanced condition by the movement of contact 12a by motor 17 in correspondence with the lowering of tachometer 10 voltage with the fall in speed of motor 3 and the component 9c has no effect in motor 3. Actuation of switch 18 causes winding 17b to restore balance of the bridge when, for example, replacement of the winding-reel is necessary. In a further embodiment, the metadyne 8 has two further fields 8c, a constant field 8b and a field 8c varying directly with the armature current of winding motor 3, the input 9b to the thermionic device 9 being dispensed with.
