Title: A method for film evaporation and an evaporator for using the method
IPC: B01D1/06
Filed: 1964-04-16
Abstract: 1,066,174. Film evaporators. ATLAS A.S. April 16, 1964 [April 17, 1963], No. 15759/64. Heading BIB. In a film evaporator the liquid to be evaporated is supplied intermittently to the evaporation surface, the pauses in the supply lasting long enough for the film to decrease greatly in thickness, and for a portion to become dry. The evaporator of Fig. 1 has a rotating drum 1 connected with a container 3 having a supply pipe 4 and a vapour outlet 5. Pump 8 pumps the liquid up through pipe 10 and out through nozzles 11 and 12 to form a film which flows down the drum wall and evaporates. The drum rotates at a speed such that the upper part of the film has become dry when that part next comes under the influence of a nozzle 11 or 12. In a further embodiment, Fig. 5, the evaporator has a plurality of pipes 48 and 52 with heat exchange ribs 49 and 53, and a valve 57 controlling the supply of liquid from pipe 61 via pump 64 in turn to pipes 52 and 48. The vapour passes from top of pipes 48 and 52, through container 50 and pipe 67 to outlet pipe 62. Figure 6 shows horizontal pipes 70 and 71 containing heated liquid within containers 68 and 69, the liquid to be evaporated being supplied through pipe 73. When an adequate amount of liquid is in the containers and valve 77 is opened and on account of evaporation a vapour overpressure builds up in container 69 so forcing liquid through pipe 72 to container 68 and laying bare pipes 71 which at first are covered by a thick film. When this film has evaporated the valve 78 is opened and valve 77 closed and the evaporation then takes place in container 68. Other embodiments disclosed include the two containers 68 and 69 housed in one container with a vertical partition wall and through pipes, and pulsators controlling liquid supply to pipes acting as evaporator surfaces.

Title: Improvements in or relating to mechanical handling equipment
Inventor: ALLBESON ERNEST NEEDHAM
IPC: B21B39/18
Filed: 1963-04-23
Abstract: 995.467. Rolling; shearing. BRIGHTSIDE FOUNDRY & ENGINEERING CO. Ltd., E. N. ALLBESON, and F. STARKEY. April 23, 1964 [April 23, 1963], No. 15968/63. Headings B3M and B3W. Apparatus for guiding billets from a furnace 16 to the first stand 18 of a rolling mill includes a switch guide 45, a profiled guiding roll 132, and a pinch roll 88 which co-operates with a lower pinch roll 108, Fig. 4. The pinch rolls and switch guide are transversely adjustable in order to guide a billet to a desired pass of the mill. The upper surface of the switch guide is curved so that whilst the guide is being employed to guide a billet into a particular path, other billets simultaneously being rolled, are lifted clear of the plane occupied by the guideway. The switch guide 45 has a curved upper surface and converging side walls 43 and is mounted on a carriage 26 which is slidable by a piston-cylinder assembly 28 along fixed bars 24. Additionally, a bracket 34, with which the piston of the assembly co-operates, is adjustable by a screw relative to a support 22. A limited transverse adjustment of the guide 45 relative to the carriage 26 is possible, using a further screw 70. Vertical guide adjustment is effected by a piston-cylinder assembly 48, acting through a linkage (Fig. 3, not shown). The larves pinch roll 108, having cylindrical ' and frusto-conical ports 128 and 130, is attached to a bell-crank lever connected to the carriage 26. Transverse movement of the carriage 26 thus adjusts the roll. A piston 120 shifts the roll vertically in order that ports 128 and 130 can co-operate with similar ports on the roll 88, the cylindrical or frusto-conical portions ports being used according to whether the billet is to be presented flat or tilted. The rolls 132 and 88 are transversely movable by sliding supports 74 and 75 on a base 20. Such movement is accommodated by a telescopic joint 98 in the driving shaft of the roll 88. Following the roll 88 are two flying shears 146, each including pivoted, oscillating blades 160, Fig. 1, mounted on support 162 and 163. A lever arm 170 of the upper support 162 is operated by a double-acting fluid-operated piston 174 such that when the blades are shifted to contact a billet, they are forced together by the billet to the position shown. Should the shear be operated to cut off a cobble, the blades can be rotated by the piston 174 to push the remainder of the billet to the left. Pivotal movement of the upper support is transmitted to the lower one by a toothed bar 168 co-operating with gear segments 166 on the supports. The frame containing the flying shears is adjustable, by eccentric bushes 152, relative to the mill stand 18, so that the reaction of shearing can be taken by the mill.

Title: Method of chromium electrodeposition
IPC: C25D5/00
Filed: 1966-04-13
Abstract: In electroplating a metal base with chromium using a chromic acid bath, an anode is used comprising a body of titanium partially covered with lead or lead alloy.  By this means only these parts of the anode are effective, such anode being specially suitable in plating articles of irregular shape.  The anode may be produced by first cleaning the titanium body, e.g. with acid or by liquid honing, heating the body and applying a lead-tin solder including antimony, zinc, and ammonium chloride.  The solder may be applied in selected areas only and a layer of lead containing about 4% by weight of antimony or tin is then cast over the solder-coated areas.

IPC: B64C29/00
Filed: 1960-05-06
Abstract: 913,312. Jet propelled aircraft. ROLLS-ROYCE Ltd. May 1, 1961 [May 6, 1960], No. 16195/60. Class 4. A jet propulsion engine for an aircraft has a jet pipe 17 terminating in a first propulsion nozzle 18, and a branch exhaust duct 35 branching off jet pipe 17 and terminating in a second propulsion nozzle from which the jet gases may be discharged, the second nozzle comprising a frame member 44 which carries a plurality of jet deflector vanes 52 which extend parallel to each other and means for moving frame member 44 relatively to its branch exhaust duct so as to vary the direction in which deflector vanes 52 carried by frame member 44 deflect the jet gases. Extending downwardly from each wing of an aircraft is a strut 10 which supports two nacelles 11, within each of which is mounted a by-pass jet propulsion engine 12 comprising low and high pressure compressors 13, 14, combustion equipment 15 and high and low pressure turbines 16. Passage 19, receiving compressed air from compressor 13, is arranged to communicate by means of a valve mechanism, with a plurality of angularly spaced apart pipes 20, which communicate with jet pipe 17 downstream of turbines 16, and with a plurality of angularly spaced apart passages 21, which constitute a volute assembly 22 from which air may be supplied via conduits 23 to attitude control nozzles on the aircraft. The valve member 24 has a plurality of obturating members (not shown) spaced apart by a similar amount to the spacing of pipes 20, and also has a plurality of angularly spaced apertures, each one of which is between each adjacent pair of obturating members. Member 24 may be rotated by a motor 33 to positions in which either all the by-pass air is passed through pipes 20 to jet pipe 17 or only part of the by-pass air flows through pipes 20 and the remainder passes through passages 21 to the control nozzles. Mounted within jet pipe 17 on trunnions 38 is a valve member (not shown) which is movable by a ram 36a between the positions in which all the exhaust gases pass either through duct 35 or through the downstream portion of pipe 17 to nozzle 18. At the downstream end of each duct 35 in a frame member 44 having aerofoil shaped deflector vanes 52 and rotatable with respect to duct 35 by means of a motor 53. By rotating frame member 44 from the positon shown in Fig. 4, in which the exhaust gases are vertically downwardly directed the gases may be deflected forwardly or rearwardly. In an alternative assembly of deflector vanes, Figs. 5, 6, 8 (not shown), the support members for the vanes are mounted so that they are able to expand lengthwise when heated by the gases passing therethrough, and the vanes themselves, are able to expand lengthwise by means of sliding joints on their support members. Specification 900,603 is referred to.

Title: High frequency submarine cable
IPC: H01B7/14
Filed: 1927-06-17
Abstract: 286,529. Beatty, W. E., (Bell Telephone Laboratories, Inc.). June 17, 1927. Cores for cables. - Relates to a cable, particularly intended for use as a submarine telephone cable, in which a central conductor is surrounded with two layers of conductors wound helically in opposite directions, the surrounds and the conductor being in direct contact with one another. According to the present invention, the conductivity of the helical surrounds is so proportioned that the circular components of the current carried therein sets up equal and opposite magnetic fields and thus substantially avoids the generation of eddy currents in the conductors. In the construction shown, a central conductor 10 is surrounded by the oppositely-wound helical conductors 11, 12 which, in turn, are surrounded by loading material 13, insulating material 14, jute 15, and armouring 16. The conductors are combined to form one insulated electrical path, and the thickness of the helical surrounds are proportioned to allow for the fact that at the higher frequencies the distribution of current through a conductor is not strictly uniform. The armour wires 16 have a very long lay and are made of steel heavily copper plated, or of non- magnetic highly-conductive material, because a large part of the return current is carried by the armour. In another construction, a return conductor is provided consisting of two oppositelywound helical conductors insulated from the central conductors and proportioned according to the same principles.

Abstract: 1359165 Glass laminates GLAVERBEL 21 May 1971 16282/71 Heading B5N [Also in Division C1] A plurality of sheets, including at least one glass sheet, are secured together by a frame and/ or by an intervening organic sheet in facing relationship and one glass sheet is subjected over at least part of its area to a rectifying treatment which improves the face of such sheet by reducing the impairment of that face by faults liable to cause stress concentrations when tensioning forces are applied thereto, the sh eets being secured together so that at least the improved face is located internally. The rectifying treatment may be a fine-polishing treatment, a chemical dissolution, as by a medium containing fluorine ions, of a surface layer having a thickness at least equal to the deepest fault present. The glass sheet or sheets may also have treatment such as thermal or chemical, ion-diffusion, tempering to give compressive stresses in the faces of the sheets; or may be stressed by assembling the sheets so that at least the one sheet is held in a state of elastic flexure, and the sheets may have differing resistances to breakage by flexure. The differing resistances may be achieved by selecting sheets of different thickness and/or by chemical tempering. The sheets may be flat or curved and may, as shown, have differing curvatures, which are secured together with or without an intervening plastics sheet, as 14, 15, 16 or 21, 22 and be held at a further different curvature in a frame (17, not shown) or 23.

Abstract: 424,112. Oil engines. WITKOWSKI, S., 32, Chemin de Grange-Canal, Geneva, Switzerland. May 31, 1934, Nos. 16312 and 16313. Convention dates, June 9, 1933 and May 7, 1934. [Class 7 (iii)] An ellipsoidal combustion chamber 20 is bounded in part by a partition 19 extending across the cylinder and is completed by a portion 27 of the head of the piston, and fuel is injected through a passage 24 in the partition 19. The partition, which is semicircular in plan is formed as an intermediate member 17 inserted between the head 18 and the cylinder 16, and the passage 24 discharges into an inclined passage 25 which communicates with both the combustion chamber and the cylinder, so that air compressed between the part 28 of the piston and the lower side of the partition blows the fuel into the combustion chamber. Any fuel not ignited by the sparking-plugs 31, which are arranged at the face of the ellipsoid collects on the top wall of the partition and is vaporized. A single valve 34 serves for inlet and exhaust. In a modified construction, separate inlet and exhaust valves are used, the partition 19 is formed integral with the cylinder head, and the top of the piston slopes continually downward instead of being formed as shown.

Title: Improvements in or relating to apparatus for use in photographic reproduction
IPC: G03B27/06
Filed: 1920-06-16
Abstract: 169,010. Kulus, M. M. June 16, 1920. Printing-apparatus. - Consists principally in paper feeding and gripping mechanism in machines for taking successive prints from a photographic negative on a continuous strip of sensitized paper of the type comprising an enclosed light chamber with a negative holder frame, means for intermittingly feeding the paper strip, for pressing the strip into contact with the negative, and for simultaneously illuminating the light chamber for an automaticallycontrolled period. In the machine shown, the paper strip 16 passes from a roll 13 between laterally-adjustable guides 14 and over the negative at the top of a light box 12 to a reciprocating gripping and feeding device, Fig. 7. This device consists of a block 24 sliding on guide-bars 23 and having a cross-bar 26 mounted upon it, beneath which bar the paper strip passes. A bow-spring is secured at one end to the block and at the other to a bar 28 slidably mounted in the block. On the bar 28 being pulled forward the spring 30 is first caused to bow and to grip the paper strip between a pad 31 and the cross-bar 26, and subsequently a stop 28a on the bar 28 contacts with the block 24 and draws it, together with the paper, forward. The bar 28 is intermittingly operated by a head 32 sliding on the bars 23 and connected by a spring catch 38 to the bar 28. The head 32 is moved forward by a cord 33 attached to a crank-pin on a disc 20 on the operating-shaft 18, the crankpin being adjustable in order to vary the throw of the head and hence the feed of the paper. The reverse movement of the head 32 is effected bv a weighted cord 36. The free end of the paper is held beneath a pivoted flap 46 which, alternately with the feeding movements, is made to bear upon it by the action cf a cam 22 on the operating-shaft, which locks a lever 47 having a resilient connection 50 to a rod 48 connected to the flap. Simultaneously with this action a plate 40 mounted above the light-box 12 on upwardly spring-pressed plungers 41 is lowered to press the paper into contact with the negative by means of vertically-moving rods 42 resiliently connected to a lever arm 44 operated by a cam 21 on the shaft 18. The lamp 51 in the light box is illuminated by a pneumatically-controlled switch operated by a pin 69 on the disc 20, which contacts with a lever 68 and also causes a rubber ball 59 to be compressed between plates 65, 66. An air-bulb 57, Fig. 6, connected to the ball 59 is thus inflated and causes contact between the points 56. An air vent 62 containing an adjustable needle-valve allows the time of exposure to be varied.
