Title: Improvements in or relating to sheet handling apparatus
IPC: B65H29/60
Filed: 1940-01-25
Abstract: 535,149. Sheet delivery apparatus. STEVENS, A. H. (Miller Printing Machinery Co.). Jan. 25, 1940, No. 1556. [Class 100 (i)] A sheet-delivery apparatus especially applicable for delivering sheets from a cutting or creasing machine comprising a cylinder 14 and a reciprocating bed is constructed so as to permit continuous operation with two receiving supports 89, 90, and with means to deliver the sheets to the desired support. This means includes at least one reciprocating conveyer 36, Fig. 3B, and a sheet-deflecting means 77 which can be set to deliver the sheets from the conveyer 36 either to the support 90, or to a further conveyer 37, Fig. 3A, which reciprocates with the conveyer 36 and from which the sheets are finally delivered to the support 89. From the cylinder 14 the sheets are delivered by a stripper 26 to delivery tapes 25 mounted on fixed pulleys driven from the cylinder 14, upper tapes 28 co-operating with the tapes 25. The sheets are received from the fixed tapes by the tapes 47 of the reciprocating conveyer 36 and are held against the pulley 45 of the tapes 47 by discs 50. The pulley 45 is held by a brake and driven from a fixed rack 56 by means of a unidirectional clutch which prevents motion of the tapes 47 as the conveyer 36 moves away from the cylinder 14, but permits movement of the tapes when the conveyer moves in the opposite direction. When the deflector means 77 is set as shown in Fig. 3B the sheets are carried over the conveyer 37 and are delivered thereto as the conveyer 36 returns towards the cylinder 14. Subsequently the conveyer 37 delivers the sheet to the support 89. If the deflector 77 is set in a raised position the conveyor 36 delivers the sheets direct to the support 90, the tapes of the conveyer feeding the sheets to the pile as the conveyer returns towards the cylinder 14. The conveyers 36, 37 are similarly constructed and are connected by a link 76 which permits of detachment of the conveyer 37 and permits of the employment of only one conveyer and pile support. The supports 89, 90 are lowered by interconnected ratchet-and-pawl mechanism of known kind operated from a camoscillated bell-crank 100 which also operates jogging-devices 122, 123 for acting on the side edges of the pile to keep the edges square. Reference is made to U.S.A. Specification 2,141,418.

Abstract: 606,727. Railway vehicles. BUDD MANUFACTURING CO., E. G. Jan. 17, 1946, No. 1617. Convention date, Jan. 22, 1945. [Class 103 (vi)] A vehicle is provided with a separate end underframe and comprises a centre sill of box-section, the vertical walls of which are split in a horizontal plane and the lower section on each side of the split is splayed outwards towards the buffer beam, a plate bridging the edges of the split sections to form a roof for an openbottom box for a coupler. The end underframe comprises a centre sill 20, having vertically arranged channels 25, Figs. 1, 3 with top and bottom plates 32, 34, the plates terminating on the inboard side of the bolster 21 in a bulkhead 31 against which the end of the body centre sill 69 abuts, the sides of the sill 69, Fig. 6, nesting between the sides 25 of the end underframe sill to which they are secured by rivets 70. A transverse beam 71, Fig. 1, is attached to the sill 69 and forms an abutment at 28 for the inboard end of the centre sill channels 25. The bolster beam 21, Fig. 7, comprises side plates 36 welded to upper and lower plates 33, 35, the outer ends being closed by a plate to which the body side posts 42 are welded. The side plates 36 cross the centre sill 20 by means of web plates 39 welded between the side channels 25 to form a box section for the housing 37 of the bogie pivot, the side channels being strengthened by plates 38 connected at one end to the bulkhead 31 and at the other to a bulkhead 43. Beyond the bulkhead 43 is another bulkhead 44 which forms an abutment for the draft gear 65. At this point the centre sill is provided with plate 51, Figs. 3, 5, 8, intermediate the upper and lower plates 32, 34 which extends forwardly to an end transverse beam 23, the parts of the side channels 25 below the intermediate plate 51 being splayed at 48 to permit the coupler head 66 to swing laterally. Collision posts 63 and bumper bar 64 surround the ends of the splayed portion 48 and a bridge plate 68, Fig. 8, closes the bottom of the centre sill under the draft and buffing gear 65.

Patent GB-651073-A (GB)
Title: Improvements in or relating to the preparation of esters of alpha-beta unsaturated monocarboxylic acids
IPC: C07C69/54
Filed: 1948-01-20
Abstract: Esters of alpha-beta unsaturated monocarboxylic acids are prepared by continuously passing vapours of a mixture of an aliphatic beta-lactone having a hydrogen atom on the alpha carbon atom and an alcohol, composed only of carbon, hydrogen and oxygen atoms, at a temperature in the range 150-300 DEG  C., through a reaction chamber in contact with an activated carbon catalyst. The process is applied particularly to the preparation of acrylic acid esters from propiolactone.  Suitable beta-lactones are those of the general formula <FORM:0651073/IV (b)/1> where R1 may represent hydrogen or an alkyl radical, e.g. alpha-methyl-propiolactone, which yields methacrylic acid esters, alpha-ethyl-beta - propiolactone which yields alpha - iso-propylacrylic acid esters, alpha-butyl-beta-propiolactone which yields alpha-butyl-acrylic acid esters, beta-butyrolactone which yields crotonic acid esters, alpha-methyl-beta-butyrolactone which yields tiglic acid esters and the like.  Suitable alcohols are methyl alcohol, ethyl alcohol, propyl alcohol, n-butyl alcohol, hexyl alcohols, octyl alcohols, nonyl alcohols, n-decyl alcohol, n-undecyl alcohol, cetyl alcohol, n - dodecyl alcohol, n - tetradecyl alcohol and other primary alcohols, secondary butyl alcohol, tertiary butyl alcohol, allyl alcohol, beta-ethoxy - ethyl alcohol, diethylene glycol monoethyl ether, cyclohexanol, furfuryl alcohol, ethylene glycol and other alcohols which are in the vapour phase in the temperature range in which the reaction is conducted.  The catalyst used may be bone charcoal, wood charcoal or mineral charcoal.  It is desirable that a current of nitrogen should be passed through the reaction chamber and that a substance which prevents polymerization, e.g. copper, copper salts, hydroquinone, catechol and phenyl-beta-naphthylamine should be present during fractionation of the product in the preparation of acrylic acid esters.  In the examples, beta-propiolactone is reacted with (a) ethyl alcohol to give ethyl acrylate and (b) methyl alcohol to give methyl acrylate.  Specification 649,028 is referred to.

Title: Improvements in cigarette making machines
Inventor: WHITT HERBERT LESLIE
IPC: A24D1/00
Filed: 1950-01-24
Abstract: 682,696. Cigarette-making machines. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd. Nov. 27, 1950 [Jan. 24, 1950], No. 1824/50. Class 130. In a continuous rod cigarette-making machine a retarding element 24 is operated at timed intervals by a cam 30 to contact the tobacco filler as it moves beneath a tapered tongue 21 leading to the wrapping device 22, whereby the distribution of the tobacco in the filler is adjusted. The element 24 is reciprocated by the cam 30 so that it projects at timed intervals through a hole 25 in the tongue 21 and contacts the filler. To produce dense-end cigarettes, the element 24 is timed to contact the filler at a point just in front of the positions 33 at which the filler, after wrapping, is cut to produce cigarettes, whereby the density of the tobacco filler is increased around the point 33. In a machine producing double-length cigarette sections which are bisected after mouthpieces have been attached to each end to produce two mouthpiece cigarettes, the element 24 may be timed so that the density of the tobacco is increased either adjacent the mouthpieces or at the free ends. The device is also applicable to the machine described in Specification 647,457 in which a composite filler is formed by an intermittently rotating wheel which inserts double-length mouthpiece sections into the tobacco filler. The action of the wheel causes an increase in density of the filler adjacent the mouthpiece sections and the element 24 is timed to restore the tobacco sections to uniform density.

Abstract: 537,626. Directive wireless systems.' MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 30, 1940, No. 1875. Convention date, Jan. 30, 1939. [Class 40 (v)] The signals received on a constantly-rotated frame aerial 5, Fig. 1 are fed through slip-rings 7 to a receiver 9 which being also coupled to a non-directive aerial 11, gives a cardioid response of the kind shown at 47, Fig. 3. Part of the output from the receiver 9 is fed to an A.V.C. unit 27, which serves both to regulate the gain of the receiver 9, and to feed to a slip-ring 17 a modulating current of frame-rotation frequency from which static interference is cut-out by a filter 33. The indicator 23 is of the kind described in Specification 537,627, and is connected to the segments 21 of a commutator ring 19 to which the modulating current is fed through the slip-ring 17 and a rotating brush 16. Since the position of the brush 16 is fixed, relatively to the frame aerial, it provides a standard phase with which that of the varying signal pick-up is compared to give the required bearings.

Title: Flash evaporator
IPC: B01D3/06
Filed: 1960-01-19
Abstract: <PICT:0906611/III/1> <PICT:0906611/III/2> <PICT:0906611/III/3> In a flash distillation apparatus, particularly for water, comprising a shell 5 enclosing an evaporation and a condensation section, feed liquid supplied through an inlet 6 (Fig. 2) is caused to be deflected twice on its way to the excess feed outlet 13, the first deflection being effected at 15 and the second by the arcuate arrangement of plates 17 which separate the evaporation section from the condensation section 9.  Vapour evolved from the liquid is thus caused to pass through a spray of liquid before it reaches the condensation section 9 via the de-mister 8, and is thus freed of fine droplets of entrained liquid.  Condensate is withdrawn through a pipe 14.  Alternative means of deflecting the feed are also described, and in one of these (Fig. 5) the feed is divided by a plate 30 into two streams, each of which is separately deflected first by a deflector 15 and then by the curved walls 32, which may be extended, as shown at 34.  In this modification two de-misters 8 are provided and condensate is withdrawn through a pipe 33a.  In all cases a perforated distributing plate 35 (Fig. 6) may extend from the first deflecting means to the shell 5, to reduce the tendency of unflashed feed to rush from one end of the apparatus to the other when the apparatus is installed in a ship and the ship is in motion.  The apparatus may operate under reduced pressure.

Title: Improvements in or relating to electric switches
IPC: H01H71/52
Filed: 1925-01-24
Abstract: 250,696. Cox, F. B. Jan. 24, 1925. Automatic circuit-breakers.-Electric switches of the kind provided with a time-limit, no-volt, or overload release, and more particularly of the kind having percussive releasing devices returned to normal position by operation of the switch as described in Specification 233,411, have the switch member A (co-operating with a fixed contact a<1>) held in the " on " position by releasable connection with a handle-member B, which is itself held " on " against the action of a switchopening spring a<2> by a detent b<1>. The connection between the members A, B may be a detent c<1> pivoted to one member, engaging a pin on the other, and provided with an arm c<2> which is struck to release the switch by an abutment d<2> on a striker-bar D. The striker D is held against the action of a spring d<1> by a normally-energized no-volt or overload release device F. The spring d<1> may be tethered to the switch-arm A, or, as shown, to the handle B. When released, the switch-arm A moves to the position shown in dotted lines, and the parts are reset by first rotating the handle B anti-clockwise until the detent c<1> engages, and then returning to the fullline position shown. The parts A, B, D may be on separate axes, or on a common axis O. In a modification, the spring d<1> passes over the axis O, and thus tends to hold the striker-bar off. In this case the no-volt &c. device is arranged to throw the bar D over the dead-centre, the striker movement being then completed by the spring. In a further modification, the arm A, instead of co-operating directly with a fixed contact, operates a separate contact arm co-operating with a fixed contact which may be oilimmersed. A modification is also described in which a contact-member with linear movement is used. Fig. 6 shows a further form in which the member B is modified for operation by a cam G with a handle g<2>, this form being suitable for use where a series of switches are to be closed successively by corresponding cams G on a common shaft g<1>. Specification 234,171 also is referred to.

Filed: 1921-01-15
Abstract: 158,548. Aktieselskabet Jajod. Feb. 7, 1920, [Convention date]. Disc apparatus.-A machine for grinding cutters &c. is provided with automatic mechanism for moving the cutter teeth along the grinding- disc and for giving the cutter a step-by-step rotation to bring a fresh set of teeth in position for grinding. In the machine shown the grinding- disc 2, mounted in adjustable bearings on a fixed bracket 3 of a frame 1, acts on cutters 18 strung on a spindle 17 of a rotatable chuck 19. The chuck is mounted on a sliding table 7 reciprocated by helical guides 10 on a rotating drum 8. A ratchet-wheel 20 on the chuck is normally engaged by a pawl 21 to hold the work against rotation, but when the table 7 has nearly reached the end of its stroke to the right, a screw 25 on the pawl 21 comes in contact with an abutment 26 on the worm-wheel 13, thereby releasing the pawl and the chuck. To rotate the cutters one step at this stage, a second ratchet-wheel 28 on the chuck has a spring pawl (not shown) actuated through a series of levers, the last of which has a roller 34, which comes in contact with a stationary cam 35 on the frame. When the table is near the end of its travel, this system rotates the chuck sufficiently to bring the next set of teeth into position.

Abstract: 1,255,704. Cutting and welding by fusion. COMPAGNIE GENERALE D'ELECTRICITE. 14 Jan., 1969 [15 Jan., 1968], No. 2206/69. Headings B3R and B3V. [Also in Divisions G2 and H1] In a laser welding, boring or cutting arrangement in which the outputs of a plurality of lasers 1-4, Fig. 1, are concentrated by optical systems on to a single point on a workpiece 13, damage to the optical systems by splutter from the workpiece is prevented by a partially transparent and partially reflective protective tape 44 moved relatively to the lasers. Ruby lasers pumped by flashlamps (not shown) may be used, the laser outputs being passed through prisms 5-8 to a zoom lens 11 which focuses the outputs on to the required point. The protective tape 44 is continuously moved during operation and is repeatedly punctured by the laser output pulses. For boring and cutting, the focal length of the-zoom lens 11 is changed by a programmecontrolled motor 12 so as to correspond with the speed of penetration of the light beam. Programming is effected by 14 which includes a pick-up device 13 for measuring the thickness of the workpiece. The workpiece, which may be tungsten, may be moved during the welding or cutting process by a drive 17. An alternative arrangement is shown in Fig. 3 in which each laser 20, 21 is aimed at the common point and has its own optical system of variable focal length which may be either a zoom lens 36 or a lens turret 32. The common point 31 of output beam concentration is illuminated by a light source 39, which may be a continuous laser, the output of which is focused by a variable focusing system 40. The lasers 20, 21 are initially aimed at the illuminated point by a positional adjusting arrangement which comprises a fixed ring 25 carrying a member 26 capable of relative rotation, each laser being supported on a rod 28 having a lockable joint 30, the rod itself being lockable in a guide 28 in the member 26. In this arrangement a small proportion of the laser outputs are reflected from the surface of the movable transparent tape 44 and are detected by a calorimeter 55, the calorimeter causing adjustment of the zoom lens 36 according to the energy detected. The lasers of the arrangement may be fired in succession.
