Abstract: 1385314 Conveying workpieces AEG-ELOTHERM GmbH 26 Sept 1973 [30 Sept 1972] 45109/73 Heading B8A Apparatus for handling workpieces 19 undergoing induction heating and quenching comprises a lifting beam conveyer 20, an intermittently operated rotary carrier 4, 5, an induction heating unit 17 and a tank 2 from which the workpieces are discharged by a chain conveyer 36. Should the transfer from the beam conveyer 20 to the rotary carrier not take place, one or more further operations to transfer the workpiece are made before the workpiece is withdrawn. The conveyer 20 has beams 22 movable in either direction in a circular motion, and has fixed beams 21 with workpiece rests 24. Rests 24<SP>1</SP> are in alignment with a pair of workpieceengaging centres 7 mounted in arms 5 of the rotary carrier when the arms are in a loading position 16. At a heating station 17 an inductor is shown in a working position but may be moved to a non-working position when workpiece 19 is to be indexed to a quenching and unloading position 18. One centre 7 of each pair of centres is driven continuously to rotate a supported workpiece. If a limit switch 25 detects a workpiece 19<SP>1</SP> correctly supported in the rests 24<SP>1</SP>, centres 7 engage the workpiece which is then indexed to the heating and quenching stations 17, 18. If the centres fail to engage the workpiece satisfactorily, the centres are re-opened and the workpiece lifted by reversal of the drive for the beams 22 to a position 38 from whence the workpiece may be removed. Alternatively, the beams 22 may lower the workpiece to a level below the centres 7 preparatory to initiating a second series of operations to correctly position the workpiece between the centres. Automatic operation is controlled by limit switches 13, 13<SP>1</SP>, 14, in addition to the switch 25.

Abstract: 1488534 Preparation of arteries SOLCO BASEL AG 31 Oct 1975 [11 Nov 1974] 45405/75 Heading A2D A process for the preparation of arteries for use in heterologous transplants comprises obtaining a length of animal artery free from surrounding tissue, any collateral vessels being sealed off, removing muscle tissue and elastic fibres from the wall of the artery by proteolytic splitting whereby a solution containing a proteolytic enzyme at a pH at which said enzyme is effective is passed continuously through the artery and subjecting the collagen tube thereby produced to tanning by passing continuously therethrough a buffered crosslinking solution whereby the density and firmness of the tube is increased. The artery is preferably a carotid artery of bovine, porcine or ovine origin, suitably obtained from a young animal. The enzyme is preferably ficin, trypsin or papain and the tanning solution suitably contains dialdehyde starch, glyoxal, polyacrolein, formaldehyde, dialdehyde cellulose or glutaraldehyde. The density and firmness of the tubes are increased to such an extent that the tubes should be able to withstand a pressure of 240 mm Hg gauge. The method may be carried out in the apparatus shown in the accompanying Figure where the appropriate proteolytic enzyme-containing solution and the tanning solution are consecutively and continuously passed through arteries 1 by means of the circulating means consisting of the cylinder 8. tube 10, pump 11, reservoir 5 and tubes 2.

Abstract: 970,105. Model railways. W. H. MULLER, [trading as SCHRYER & CO. SCHUCOSPIELWARENFABRIK]. Dec. 4, 1962 [Dec. 5, 1961], No. 45717/62. Heading A6S. Electrically operated switch-points for monorail tracks comprise a flexible plastic switchpoint tongue-piece 6 which is integral with a straight track section 7 and carries the conductor rails thereon. Extra flexibility is obtained by deeply slotting, in staggered relation, each side of the plastic tongue 6. The switching of the tongue is effected by a bell-crank 12 mounted beneath the baseboard 1, the said bellcrank 12 being pivoted at 10 and connected to the tongue at 13 through an arcuate slot 14 in the baseboard. Completion of an electric circuit at contacts 3 causes a motor 2 to move the bellcrank through gear 18, crown-wheel 19 and gear 16 thereon, which latter gear 16 meshes with the teeth on the arm 15 of the bell-crank 12. A friction coupling 23 between the crown-wheel 19 and the gear 16 causes the drive to slip when the points are finally in line.

Title: Arrangement for supporting plate-form heat exchange matrices for recuperative heat exchange between fluids
IPC: F28F9/007
Filed: 1976-11-03
Abstract: Heat exchanger matrices of the folded strip type are set in an elongated V configuration inside a tubular casing. They are held in position by braces between opposite cover plates and between other cover plates and the casing, which braces also operate as partition walls for separating inlet and outlet channels of one of the media. The cooler of the media has inlet ducts downwards on the edges of the space inside the V and an outlet duct for upward flow at the center of the space inside the V. The other medium, which is hotter, but under less pressure, has inlet ducts with upward flow at the center of the spaces outside the V and outlet ducts with downward flow at the edges of the spaces outside the V. The hotter parts of the heat exchanger are in the middle of the structure. Bellows-type thermal expansion compensators seal the edges of the V against the casing.

Each magazine is positioned in turn by Geneva mechanism 40, 41 at a cut out 23 formed in a fixed supporting plate 5, the bottom of each magazine having a roller 110 engaging the plate surface. When positioned at cut out 23, the magazine is movable vertically by a worm gear 24 engaging a free running roller 90 provided on each magazine so that a pincers-like gripper Z may extract each each cassette or cartridge 12, and a second gripper draws out its associated order bag T. Each magazine is designed to accommodate either a 126, or a 135 cartridge. To this end, each compartment of a magazine has a pair of levers 16, 17 pivotally mounted at 43, 42 so that only one type of cartridge may be inserted, 135 as illustrated in Fig. 5 (not shown). All the levers of each magazine are interconnected so that only one type of cartridge may be loaded in each magazine. To allow 126 type cartridges to be loaded, lever 16 is turned counter clockwise and lever 17 is turned clockwise. In so doing, pins 30, 31 interconnected by a rocker 29 move so that pin 31 projects through magazine plate 13 in place of pin 30. The pins may operate switches and/or the turret may sense the position of pins 30, 31 to permit loading of only one type of cartridge. Each magazine may indicate the type of cartridge loaded.
