Patent GB-877836-A (GB)
Title: Improvements in or relating to synchronous machines
Inventor: BADER GUNTHER
IPC: H02K19/30
Filed: 1957-10-10
Abstract: 877,836. Alternators. FIMAG FINSTERWALDER MASCHINEN G.m.b.H. Oct. 10, 1957, No. 31681/57. Addition to 844,688. Drawings to Specification. Class 35. In a modification of the alternator excitation arrangement described in the parent Specification the rotating core 7 of the current transformer 5 is flattened in accordance with the number of poles so that the transformer flux is a function of the physical phase-angle of the main machine. This means that proper compounding may be achieved without the vectorial addition of the current and voltage components, so the tapped ring winding 4 may be replaced by an ordinary three-phase winding and the current and voltage components rectified and fed to the field winding separately. The voltage component may be derived from a separate stator winding as in the parent Specification or from the terminals of the main output windings through chokes. The machine may be regulated for parallel operation by an additional adjustable resistive loading of the currentcomponent rectifier. The rotating transformer may be separately driven by a synchronous motor fed from the main machine.

A heat exchange unit comprises a front plate 1, a back plate 2 and a plurality of solid blocks 3 of thermally conductive material which bridge the space between the plates dividing it into flow channels 5 for the passage of a first fluid, the plates and blocks having aligned apertures 6 to provide flow paths for a second fluid through the unit. Each block 3 can be drilled with a row of holes 4 to allow communication between flow channels 5. The holes 4 in adjacent blocks 3 may be aligned or as shown they may be staggered to improve heat transfer. The holes 6, where the units are spaced apart in the heat exchanger, are similarly out of alignment (as illustrated in Fig. 1). The blocks 3 are line welded to the plates 1 and 2 using a multi-disc revolving electrode assembly (7, Fig. 2), so that a good thermal contact can be achieved. In another embodiment (see Fig. 3) the heat exchanger units are built up from I-bars, the end flanges of adjacent bars being welded together to form the plate elements analogous to plates 1 and 2. The blocks 3 and plate elements 1 and 2 can be made from either metal or graphite.

Title: Apparatus for use in tempering glass
IPC: C03B35/20
Filed: 1935-11-20
Abstract: 466,037. Tempering glass plates. AMERICAN SECURIT CO. Nov. 20, 1935, No. 32218. Convention date, Dec. 4, 1934. [Class 56] A device for supporting a glass plate in a vertical position during the operation of tempering comprises flexible metal members which engage the edges of the plate at points below the centre, and exercise downward pressure at points above the centre of the plate. The device comprises a frame 1 suspended from trolleys 4, which run along an overhead rail 5 to enable the frame to be moved through the heating and cooling devices. A number of glass plates 10, e.g. circular port lights, are supported in the frame by the flexible metallic members. In one arrangement, a metal band 11 in the form of a depending loop extends around the lower portion of a glass plate 10, and a band 12 extends across the upper portion. The band 12 may be attached at one end to the frame and at the other end to a pivoted arm 18 the weight of which provides sufficient tension to hold the glass plate in place. Alternatively, the band may be attached at both ends to pivoted arms 26. In another construction, a band 27 may be attached at one end to the frame while the other end is provided with a weight 30 to provide the necessary tension. Instead of the upper bands 12, 27, a bar which slides between the side members of the frame may be used to support the upper edge of the plate. A flexible metal band 40, or a chain 21, may extend around a glass plate 10, and be attached to bolts 22 which are passed through holes 23 in the frame. The use of a chain enables rectangular plates to be suspended. The band may also be suspended from the frame by a lazytongs, the weight of the plate applying the required tension to the band. The bands may be made of refractory metal, such as nickel chromium, and they may be insulated from the glass plates by means of facing strips of suitable material, such as asbestos. The insulation may be provided, also, by means of asbestos cord wound on the band.

Title: Improvements in and apparatus for the manufacture and production of acetaldehyde from gases containing acetylene
Filed: 1936-11-25
Abstract: In the production of acetaldehyde from gases containing comparatively small amounts of acetylene by leading them through a reaction vessel in the same direction as a catalytic liquid, a substantial excess of which is circulated per hour, as described in Specification 460,145, the non-purified gases are introduced in a finely dispersed state through a nozzle into a reaction vessel free from filler bodies.  The gases and catalytic liquid may first be mixed and the mixture forced through narrow slits or other apertures.  A catalyst solution <PICT:0484500/IV/1> consisting of dilute sulphuric acid containing mercury and iron sulphates is charged into a vessel A and is circulated by pump B through a mercury container C and nozzle D.  It is heated to 90 DEG  C. and electric arc gases are forced in through pipe F.  Part of the solution is withdrawn through pipe H, freed from sludge produced from the impurities in the gases, and oxidized so that at least 20 per cent of the total iron in the solution is always in the ferric state as described in Specification 466,569.  Normal or increased pressure may be used.  Specification 458,583 also is referred to in the Provisional Specification.

IPC: G03D9/00
Filed: 1965-07-28
Abstract: 1,112,125. Sheet separating apparatus. GEVAERT-AGFA N.V. 28 July, 1965 [30 July, 1964], No. 32320/65. Heading B6H. [Also in Division G2] Two sheets 10, 11 lying in contact are separated by passing them between conveyer rollers 12, 13 (Fig. 1b until the leading edge trips a microswitch 14, which causes the lower roller 13 to stop, and the upper roller 12 to rotate in the reverse direction (Fig. 1c). This drags upper sheet 10 back in a direction opposite to that of its previous travel, so that it forms a loop 15, the sheet eventually passing entirely above roller 12 (Fig. 1d, not shown). Fig. 2 is the actual arrangement of the apparatus. The exposed light-sensitive sheet 11 and the image-receiving sheet 10 are led through the bath 21 of processing liquid, and then pressed together between rollers 23, 24 to effect an image transfer. The two sheets, adhering together, are guided towards rollers 25, 26, which are caused to rotate by a motor-driven roller 27 rotating anticlockwise. Roller 26 is a hollow cylinder having a rubber covering 33, and rotates freely on a stationary shaft 34. Roller 26 carries a pawl 35 which rotates with it, the pawl engaging a ratchetwheel 36 fast with shaft 34. Thus roller 26 is prevented from rotating other than clockwise. The sheets are guided round roller 26 by a set of fingers 47, which can be alternated between a forward position and a retracted position by the mechanism of Fig. 3 (not shown). As the sheets pass round roller 26, and then between rollers 26, 27, the leading edge eventually encounters a microswitch 60 which, by means of the circuit arrangement of Fig. 5 (not shown), reverses the rotation of roller 27. Roller 26 remains stationary, since it cannot reverse. The leading edge of top sheet 10 is dragged backwards, until it rides free of roller 27. After a predetermined time the rollers now resume their previous movement, so that sheet 10 now passes upwards between rollers 18, 28. Sheet 11 passes forwards over plate 37, until it reaches a roll 30 formed on a hollow cardboard core 38 which can slide freely in slotted brackets 40. As the damp sheet 11 reaches roll 30, it adheres to it and becomes wrapped round it.

Abstract: 961,155. Moulding micro-cellular rubber soles on to footwear uppers. BRITISH UNITED SHOE MACHINERY CO. Ltd. Sept. 23, 1960 [Sept. 25, 1959], No. 32590/59. Heading B5A. [Also in Division F2] In a machine for vulcanizing micro-cellular rubber soles on to footwear uppers of the construction described in Specification 922,401, valve means is provided to decompress the pressure fluid before it is withdrawn from each piston and cylinder applying pressure to a sole mould, such withdrawal being regulated to produce a controlled expansion of the mould cavity. The withdrawal of the pressure fluid may be regulated by a metering device associated with a control valve incorporating temperature compensating means for providing a substantially uniform fluid flow rate through the control valve independently of variations in the viscosity of the fluid due to temperature changes. In the fluid pressure system illustrated the pressure fluid in the cylinder 8 beneath the piston 6 carrying the sole mould support 2 is decompressed by allowing a part thereof to flow to a sump S through conduits 34, 32, 76, non-return valve V5, conduit 82, non-return valves V15, V16, and a valve V14. When the pressure beneath the piston 6 has fallen sufficiently to decompress the fluid (which may comprise oil having air absorbed therein) the valve V14 is actuated by a spring 80, against the action of the fluid pressure operating through a pilot H4, into a position to interrupt the pressure fluid supply through lines 90, 88 to the non-return valve V15 so that the latter closes to stop the flow from the cylinder 8 through the valve 14. When the valve 14 has been so actuated pressure fluid is supplied via conduit 90, valve 14 and conduits 87, 60, 62, and 64 to open non-return valves V7, V8, and to change over valve V10 to supply pressure fluid from the high pressure pump P2 to the cylinder 8 above the piston 6. The piston 6 and sole mould thus descend, the fluid beneath the piston passing into the metering device M at a rate determined by the flow of fluid from beneath the piston 44 to a sump S through the non-return valve V8 and the control valve V9. The control valve V9 incorporates a temperature compensating means for the purpose stated above, and its construction is described in detail (see Division F2). Specification 859,671 is referred to.
