Title: Processes and Apparatus for the Manufacture of Reinforced Synthetic Products in Sheets.
Filed: 1966-05-19
Abstract: 1,150,164. Laminating. MANUFACTURE GENERALE DE MUNITIONS. 19 May, 1966 [20 May, 1965], No. 22223/66. Heading B5N. A process for the manufacture of sheets of reinforced synthetic plastics material comprises spreading on the flat upper part of an endless conveyer belt a layer of synthetic plastics material in the form of a fluid paste, joining a reinforcing layer to the aforesaid, still fluid, layer of material, drawing off the vapours of the volatile products used for the preparation of the paste beyond the zone in which the reinforcing layer is incorporated with the layer of material, rolling up the reinforced layer of material on a roller, and cutting along at least one generating line to obtain at least one sheet of reinforced synthetic plastics material. In a machine described for carrying out the process, an endless conveyer belt 1 receives on part of its upper run 1a supported by a plane support 6 fluid paste M supplied from a tank 7 by a spout and transverse distributer 9, the fluid paste forming a layer C the thickness of which is adjusted by a transverse scraper (not shown). A reinforcing sheet A, e.g. a woven or non-woven sheet based on textile, vegetable, animal, or synthetic fibres or metallic threads, fed from a supply roller 11 is joined to the layer C at a roller 10. Vapours of the volatile products used in the production of the paste M are removed by suction acting via vacuum boxes 12 before the reinforced material is wound on a roller 14, on which it is subsequently cut. The fluid paste M may be of leather fibres with a binder of synthetic rubber, and preferably the sheet A is impregnated before it reaches the roller 10 with a binder compatible with the material of the paste, e.g. the same as that of the paste. In a second embodiment of apparatus a thin layer of paste is applied to the conveyer belt and a further thin layer of paste is applied to the upper surface of the sheet A after its application to the first paste layer. In a further embodiment the roller 10 is provided with prongs so that the sheet A is embedded in the paste layer.

Filed: 1944-11-13
Abstract: <PICT:0602240/III/1> <PICT:0602240/III/2> <PICT:0602240/III/3> Hydrocarbons are converted by passage through a series of two or more contact masses a, b, c, Fig. 2, separated by cooling and mixing zones d, e, provided with pipes 6, 7 for the admission and withdrawal respectively of hydrocarbon vapours or liquids.  The reaction is conducted to such a point that the carbon deposit on the catalyst yields, upon regeneration, more heat than is consumed by the subsequent endothermic reaction.  Charging stock is passed into zone a below reaction temperature and leaves it above that temperature; it is cooled in space d by addition of more hydrocarbons to below reaction temperature and passes through zone b, where it is again heated, and subsequently cooled in space e, and so on.  If the intermediate additions of hydrocarbon are liquid they should be prevented from entering, the following contact zone in an unvapourised state.  This may be effected by fitting a constricted aperture 12a, Fig. 4, followed by a baffle plate 13, or by placing in the cooling zone a layer 19, Fig. 5, of porous material, which may be supplemented by a liquid trap 20. The catalyst beds may be of successively diminished thickness in the direction of flow.  Suitable catalysts are described in Specification 519,808.  Examples describe the conversion of East Texas gas oil at various temperature ranges between 845 and 993 DEG  F.

Title: Process and apparatus for improving the dimensional stability of fibres obtained from crystallizable propylene high polymers
IPC: D02J1/22
Filed: 1957-07-15
Abstract: <PICT:0813891/IV (a)/1> Stretch-oriented elastic fibres of crystallizable polypropylene are heated at temperatures and for times such that substantial shrinkage would occur in the absence of mechanical restraint, while maintaining the fibres under slight tension.  A single-stage process may be used in which heating to 80-160 DEG  C. takes place while the fibres are held to constant length, or are allowed to shrink up to 15 per cent, or (less preferably), are subjected to stretching.  Alternatively, a two-stage process may be used, in the first stage of which the fibres are heated at a moderate temperature while allowed to shrink up to 15 per cent, while in the second stage they are heated while kept at constant length, process conditions being such that, without mechanical restraint, substantially greater shrinkage would occur in the second than in the first stage.  Thus a first stage of a few seconds at about 80 DEG  C. may precede a second stage of up to 60 mins. at 80-160 DEG  C. The proportion of amorphous propylene polymer in the fibres preferably does not exceed 15 per cent.  Mono- or multi-filament yarns may be treated as above, before or after, but preferably before, spooling.  Apparatus for the single-stage process may consist of a slow inlet roll 1, hot-air chamber 2, and fast-stretching coil 3 for the prior stretchorientation, from which the fibre passes via a hot-air chamber 4 to a roll 5 and hence to a "ring"-type winding system 6.  Thus the relative speed of rolls 1 and 3 controls the initial stretching ratio, and the relative speed of rolls 3 and 5 may be adjusted to provide stretching, "constant-length," or shrinkage conditions.  Fibres treated by the above process have a lower elasticity, and so spool more regularly, than untreated fibres, and show less tendency to shrink when heated in water.

Abstract: 912,397. Control of D.C. motors; interrupters. FORD MOTOR CO. Ltd. June 22, 1961 [June 23, 1960], No. 22673/61. Classes 38 (3) and 38 (5). [Also in Group XXIII] Relates to the control of an electric motor 10 driving a wind-shield wiper. When a control switch 62 is adjusted to a high-speed position, heater element 45 is energized from battery 55 so that thermal switch 41, 42 is closed. Series field winding 21 is energized, whilst shunt field winding 34 is not excited or is partially excited through resistor 91. If the control switch is adjusted to a low-speed position, the windings 45 and 21 remain energized, the shunt field winding being now connected to the battery through switch 41, 42. In the parking position of the control switch, the series field winding is energized through switch 25 end the shunt field winding through switch 41, 42, the heater element 45 remaining energized as long as contacts 24, 26 are engaged. When a motordriven cam 31 disengages contacts 24, 26, and engages contacts 24, 28, the windings 21, 45, are de-energized the armature and series field windings being short-circuited. The shunt field winding remains energized for a short period, however, due to delay in opening the thermal switch, thus providing dynamic braking. In another embodiment, the thermal switch 42 is replaced by a dash-pot operated switch having a diaphragm associated with a push-rod which tracks upon a gear having a groove, so that once during every revolution of the gear the push-rod has an opportunity to drop into the groove, Figs. 2, 3 (not shown). The dash-pot housing has an orifice for the passage of air, and a spring for urging the diaphragm towards the gear. The switch remains closed until the armature and series field windings are short-circuited, the deenergization of the shunt field winding being delayed due to slow movement of the diaphragm.
