Abstract: 1439287 Loop steaming apparatus VEPA AG 24 Aug 1973 [31 Aug 1972] 40146/73 Heading D1L Apparatus for forming a web of textile material 12 into a plurality of freely suspended loops 14 and conveying the loops through a treatment chamber such as a steaming chamber 1 for printed or dyed textile materials, comprises a plurality of rotatable support members such as conveying or guide rollers 5, means for displacing said support memlbers, first means capable of rotating each said support member in the region of the inlet at such a speed that the peripheral speed of the member is, in use, substantially equal to the rate of feed of the material, and second means capable of rotating said support members at a slower peripheral speed as said members are displaced away from the inlet, such that, in use, loops are formed between adjacent members having different peripheral speeds, the support members being so located that, in use, each said member, contacts one side only of the material. As shown in Fig. 1 the guide rollers are secured at either end to travelling endless chains 4 which are guided through the steamer 1 by gear wheels 16, 17, 32 and 33, means including conveyor rollers 8 and/or suction drum 10 for feeding the web 12 to contact each roller 5" at its nearest point to the inlet of the steamer, means including auxiliary chains 18 and 13 for causing the rollers to rotate continuously during loop formation and the rollers 5" to rotate at a higher peripheral speed than the next roller 5' on the conveyor 4, and means for varying the spacing between successive rollers as the loops of material are formed. The material loops are thus formed by a combination of the altering spacing between, and the difference in peripheral speeds of rotation of, successive rollers in the upper part of the steamer. Figs. 2, 3 and 4 (not shown) illustrate alternative embodiments in which the material inlet is located in the lower part of the steamer 1 and the initial formation of the hanging loops is achieved by the rollers 5 as they are guided upwardly towards the ceiling of the chamber. Alteration of the spacing of successive guide rollers may be achieved by forming the chains 4 so that the links 36 (Fig. 5) thereof may be concertinaed by means of guide plates 37, 38 located immediately downstream of upper chain gear wheel 16 and adjacent one of the roller driving chains 27.

Abstract: 919,886. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 7, 1959 [Dec. 10, 1958], No. 41483/59. Class 39 (1). An ignitron or other vacuum vessel of an electric discharge device has at least part of its wall consisting of iron, the inner or outer face of the iron being alloyed with zinc.

The zinc is sprayed on to the iron wall which may be preliminarily roughened by sand blasting. The vessel is then exhausted and heated to 800-900‹ C. to cause the zinc to melt and alloy with the iron. The zinc layer may have a protective layer of water-glass during heating to prevent oxidation thereof. Prior art coatings of copper or aluminium are referred to.

Title: Method of producing a thermally and acoustically insulated pipe
IPC: B29C48/09
Filed: 1977-10-06
Abstract: Using an extruder die (1), in the process an outer pipe (2) made of thermoplastic is extruded coaxially to an inner pipe (6) fed continuously over a guide pipe (5). Then, using a mixing device (9), a reactive foam composition (11) forming the heat-insulating layer is introduced by means of a mixing device (9) into the annular space between the inner pipe (6) and the outer pipe (2). This foam composition (11) is sprayed onto a conveyor belt (7) running off from a supply reel (8). The foam composition (11) is formulated such that it does not fill the annular space until the outer sheath (2) has sufficient strength. The extruded outer pipe (2) is calibrated in a subatmospheric pressure chamber (3) partly filled with water and intensively cooled in a second chamber (4). The film used hitherto for forming a mould cavity for the insulating layer and the forming device for this film are dispensed with. <IMAGE>

Abstract: 1,019,239. Road and railway vehicles; securing load in bulk; removable bodies. EQUIPMENT MANUFACTURING Inc. Nov. 3, 1962, No. 41665/62. Headings B7B and B7L. Cargo is secured in a coad or rail vehicle body rontainer 20, Fig. 1, by a dunnage bar 24 extending between the side walls 21, 22, the latter being formed with a series of corrugations 28, 31, 33, 34 (see also Fig. 2) having spaced along the lengths thereof connector elements, in the form of ribs 42, Figs. 3 and 5, for engagement by connector elements 62 provided at the ends of the bar, each end of the bar thus being engageable with one or two corrugations and retained against movement both transversely and longitudinally of the corrugations. As shown in Figs. 3 and 4, a pair of elements 62 is secured to one end of the bar whilst another pair of elements 62 is movably secured to the other end under the urge of springs 55. Each pair of elements 62 is offset with respect to an end plate 60 in such a manner that the bar is capable of adjustment both vertically and longitudinally of the side walls by increments equal to half the width of the corrugations 70. The various positions which a plate 60 may adopt are shown in dotted, dashed and cross lines, in Fig. 5. Each element 62 can either engage a pair of opposed ribs 42 or between two pairs of opposed ribs 42. The increment of adjustment may not be obtainable at the junctions of vertical and horizontally extending corrugations as shown in Fig. 2 but may be substantially attained by adjustment of the vertical corrugation horizontally of the horizontal corrugations, as described with reference to Fig. 6 (not shown). In another embodiment, each side wall is formed of inner and outer corrugations welded together. According to a modification the connector elements on the corrugations may be grooves instead of ribs and complementary elements on the ends of the bar are then provided with enlarged corners to engage the grooves. In this case the increment of adjustment is equal to a corrugation width in the horizontal direction, and half such width, in the vertical direction.

Abstract: 967,676. Non-linear impedance networks; semi-conductor circuits. GENERAL ELECTRIC CO. Ltd., and J. EVANS-PUGH. Nov. 23, 1962 [Nov. 24, 1961], No. 42209/61. Headings H3T and H3U. A variable-impedance circuit comprises two pairs of terminals connected by a transformer 7 and by an element 9 having a non-linear voltagecurrent characteristic, e.g. a semi-conductor diode. The impedance of the diode 9 is controlled by the transistor 11. Under conditions of maximum attenuation some current is still passed by the diode because of its inherent capacitance. To reduce the unwanted signal, the coupling of the transformer 7 and the value of capacitance 8 are such that the signal transferred by the transformer is equal in amplitude and opposite in phase to the signal transferred by the diode. In a modified circuit, the diode is connected between terminal 1 and the lower terminal of the secondary winding 10.

To permit the feeding stroke of jaws 20 which effect a transverse seal across a packaging tube containing material to be varied, the feeding movement is effected by a chain or belt secured at 24 to a pulley 25 which is oscillated bodily about a pivot 391, and the chain or belt passes over a pulley 33 whose position may be adjusted to vary the stroke. The pulley 33 is mounted on an arm 35 adjustable by a hand-operated screw 38 to swing about a fixed pivot 351 which preferably coincides with the uppermost position of the centre of the pulley 25. Rotary movement of the pulley 25 is prevented by a chain 30 connecting it to a fixed pulley 31. The oscillatory bodily movement of the pulley 25 is derived through a connecting rod 26 from a crank disc 27. The mechanism is such that the position of the top dead centre of the jaws 20 is substantially unchanged when the stroke is changed. A spring 300 limits the tension in the chains. The jaws 20, which move horizontally or vertically to effect the feed of the tube, are moved in one direction by gravity or by springs.
