Title: Glueing synthetic resins
Inventor: SCHMIDT FRITZ
IPC: C08G18/10
Filed: 1964-08-04
Abstract: A polyurethane reaction product of one molar proportion of a di-isocyanate with at least one molar proportion of the esterification product of an alkane dicarboxylic acid having at least 6 carbon atoms and an alkane diol having at least 4 carbon atoms is the prescribed adhesive (as a melt or in solution) for bonding a plasticizer-containing P.V.C. or one of its copolymers to the same material or to a different material e.g. leather, rubber, wood or metal.  Suitable dicarboxylic acids are adipic, pimelic, duberic, azelaic sebracic; the diol may be straight-chained, e.g. butane 1:4 diol, pentane 1:5 diol or hexane 1:6 diol.  Mixed polyesters from more than one acid and/or diol are preferred, especially for cold sealing.  Fillers which may be added include natural and synthetic resins e.g. colophony derivatives, phenolic and ketone resins; and acetyl - or nitro-cellulose.  The heat resistance of the joints is also increased by adding cross linking agents, e.g. di- or poly-isocyanates, to the adhesive solutions.  Heating by infra-red to about 70 DEG C may be used to render layers of adhesive free from solvent, adhesive again.  One of the materials to be glued may be applied in liquid form by injection moulding to the solidified layer of adhesive.

Convention date, Oct. 27, 1933. [Class 123 (iii)] Some of the tubes in a steam boiler superheater are movable with respect to others to prevent excessive changes in superheat as the boiler rating is varied. A superheater disposed between water-tube banks consists of flat coils 26 connected to headers 28, 30, the tube lengths of each coil preferably being connected by struts which may comprise relatively movable interlocking parts. Each coil has an upper extension 38 which hooks over a bracket 36, some extensions being movable along the brackets and others being fixed between stops, or the movable coil supports may comprise studs 40 connected by members to a tubular actuator 44, 46, communicating by tubes 45, 47 with the superheater headers and caused to be moved by the engagement of thermally controlled motor-driven pinions with racks on the external wall of the actuator tubes. Tube shields 78, 80 of tiling, grooved so as to interlock with the upper and lower pairs of tube lengths in a movable coil, effect an increased shielding of the superheater tubes at high ratings, or metal plates may be employed, one such plate being located intermediately of the upper and lower plates to prevent eddying. In another construction, alternate superheater coils are fixed and the others secured to a movable controller tube. The tube-actuating motors may be thermostatically controlled to maintain a constant superheat.

Patent GB-1397636-A (GB)
Title: Labelling device
IPC: B65C11/02
Filed: 1972-07-03
Abstract: 1397636 Labelling device K D HERMANN 3 July 1972 [8 July 1971] 31077/72 Heading B8F In a hand-operated label applicator, a label tape 29 is led from a roll 34 around a separating edge 37 to a transport wheel 24, the labels being applied by a cam 31. When the handle 5 is depressed a rocker member 9, on which the cam 31 and edge 37 are mounted, is pivoted clockwise about a point 8 so that the ink roller 14 moves around the printing mechanism 17, and then a label is pressed against the mechanism 17 by the plate 11 (Fig. 2). Since the distance between the edge 37 and roller 24 is thereby increased the tape is advanced by about half a feed step. Simultaneously an angle element 22 moves a pawl 32 over the next radial pin 25 of roller 24 which is locked by a ratchet plate 35. On releasing the handle 5 a spring 26 returns the rocker arm 9, and the roller 26 is advanced by one step. A pusher 40 which is pivoted at 39 and biased towards the plate 11 moves the label past a deflector 42 to cam 31, the distance between the separating edge 37 and the cam 31 being greater than the label length. The pusher has projections on its front edge which bear against the adhesive side of the labels, and the labels may have no adhesive along longitudinal strips corresponding to the projections in order to prevent adhesive accumulation on the pusher 40. By adjusting the position of a roller 44 in slot 45 the positions of labels with respect to the separating edge 37 may be altered.

Abstract: 1,224,345. Defrosting. V. F. H. BODCHER. 1 July, 1968 [7 July, 1967; 11 Sept., 1967], No. 31273/68. Heading F4H. A refrigeration system includes a reservoir which normally receives liquid refrigerant from the condenser and supplies liquid to the expansion valve, but for defrosting supplies liquid to the condenser, where it is evaporated then supplied to the evaporator, and receives condensate from the evaporator. As shown, the reservoir 3 is divided into compartments 6 and 7 by a partition 8 and the compartments are interconnected by a pipe 9. In normal operation liquid refrigerant from condenser 2 enters compartment 7 through line 12, passes through pipe 9 into compartment 6 and then passes through line 14 and expansion device 4 into the evaporator 5. For defrosting, the compressor is stopped and a valve 17 in a line 19 connecting the upper end of compartment 7 with the upper end of evaporator 5 is opened. Liquid refrigerant from compartment 7 then passes through line 12 into the condenser, is evaporated therein and the vapour passes through line 13 into compartment 7 then through line 19 into the evaporator where it is condensed. The condensate passes through line 20, which includes a check valve 21, to compartment 6 and through pipe 9 to compartment 7. Defrosting may be initiated and terminated by a pressostat 15 or by a thermostat or timer. In further embodiments (Figs. 3 and 4 not shown), compartments 6 and 7 are located side by side and are separated by a vertical partition having an opening in its upper part. The liquid passing from compartment 7 to the condenser during defrosting is heated in line 12 either electrically or by heat exchange with an external fluid, e.g. air.

Title: Process for the productionof heavy water
IPC: C01B5/02
Filed: 1957-10-08
Abstract: In the production of heavy water by catalytic deuterium exchange between hydrogen and water in a dual-temperature system the catalyst is nickel, iron, or cobalt in the Raney form. Caustic alkali may be dissolved in the water.  The catalysts in the Raney form are prepared by alloying the metal with Al, Zn or Mg and completely or partially dissolving out the alloying metal with caustic alkali.  The catalysts may be the double-skeleton material described in Specification 806,644 prepared by compressing a mixture of metal carrier and the alloy, sintering the compressed body, and treating with caustic alkali.  The catalyst may be granules which may be used as a stationary bed suspended in the H2O.  Alternatively, the catalyst may be shaped bodies disposed in the reactors.  The caustic alkali may be KOH in a concentration 0.001 N to saturation, preferably 0.05-2 N. Pairs of towers may be connected in a cascade with hydrogen flowing in closed cycle through each pair of towers, except the first, while some of the water flowing in countercurrent is withdrawn between the towers of a pair and passed to the next pair, whence water is returned to a point having the same D concentration.  The towers work at 1-150, preferably 10-30 kg/sq.cm. with temperatures, in the cold towers 20-100 DEG , preferably 40-80 DEG C., and in the hot towers 100-250 DEG , preferably 160-200 DEG C.  The D is fed to the cascade either by feeding fresh H2 to the first pair of towers, or by contacting the H2, flowing in closed cycle through the first pair of towers, with raw H2O in a separate tower.
