Title: Improvements in or relating to the manufacture of artificial tubular packaging materials
Inventor: BERRY WILLIAM
IPC: B29C48/10
Filed: 1950-02-06
Abstract: <PICT:0675686/IV (a)/1> A flexible tubular casing 31, such as a sausage skin or other packing casing is provided with one or more tearing lines 36, which are at least as thin as the casing, such lines being bounded by ribs or ridges 32, 33, to prevent the tear from crossing the ribs which are formed of material similar to that of the casing. Such ribs may be formed integral with the casing during its formation by extrusion or they may be cemented on.  When two or more tearing lines are formed a complete strip bordered by the tearing lines is removed.  The tearing may be done by a machine. The tubular casing may be either seamed or seamless.  When forming the ribbed casing by extrusion of a molten thermoplastic into the air, a jet of cold air may be directed at the region of the ribs.  The ribs may be formed on the inside of the casing. The casing thickness may be from 0.001 to 0.003 inch and the ribs may project a like height above the casing.  The casing may be made by wrapping and sealing regenerated cellulose film around a mandrel, the sealing adhesive being a dispersion of 2 per cent cellulose in a 60 per cent aqueous solution of zinc chloride.  The casing and its ribs may also be made by extrusion of viscose into a coagulating bath, or by extrusion of molten polythene or molten butadiene-styrene copolymer or of a copolymer of 60 parts by weight of vinylidene chloride and 40 parts of vinyl chloride.

Abstract: 456,094. Lamps for interior illumination. HOLOPHANE, Ltd., Elverton Street, Vincent Square, Westminster.-(Holophane Co., Inc. ; 342, Madison Avenue, New York, U.S.A.) Feb. 3, 1936, No. 3216. [Class 75 (ii)] In a lamp for interior illumination in which a light source is associated with an opaque or prismatic reflector and a prismatic transmitting member, the light emitted from the two transmitting faces of each prism of the transmitting member always includes light from the source emitted on one side of the axis of the lamp and light from the reflector emitted at a similar angle on the other side of the axis. In the form shown, rays from a light source 2 falling on a prismatic plate 3 are concentrated into a beam bounded by the lines 5-6 and 19-20 and having a virtual focus at the point 4, whilst rays from a relatively deep reflector 21 are concentrated into a beam bounded on one side by the line 5-23 and having a virtual focus at the point 31. The points 4, 31 are equidistant from the plate 3, so that the two beams are symmetrical with respect to the axis of the lamp, and in use the light appears to radiate from a single point. In some forms, the virtual focal point 4 may be replaced by a focal line 34-35 along the axis, or by a circular focal line at right angles to the axis. The prismatic plate may be square or round and it may be in the form of a double convex lens. For a single light source the reflector is annular and the prismatic plate is formed with circular prisms, but for an elongated light source the reflector is trough shaped and the prisms are parallel. In a modification illustrated in the Specification, the prismatic plate is formed with outer concentrating prisms and inner spreading prisms.

Title: Improvements in or relating to cloth folding
IPC: D06F89/00
Filed: 1961-01-31
Abstract: 946,991. Folding fabrics. W.WULFF. Jan. 31, 1961 [Aug. 13, 1960], No. 3558/61. Heading D1S. A folding device for folding articles comprises clamping means for gripping the leading edge of an article passing around the outer surface of a rotatable drum, the clamping means being located above the outer surface of the drum whose circumference corresponds at least to the maximum length of the article being folded, the lower peripheral half of the drum being provided with pressure means for compressing the article after folding. In the arrangement shown (Fig. 9) article 11 from a calender 10 is fed to a conveyer table 12 which terminates in front of a driven folding drum 17. The article is folded transversely on table 12 by means of clamping beam 21 and is folded again above the drum 17 by another beam 21. Fig. 2 shows the fold forming mechanism. When the leading edge of article 11 reaches feeling member 28 the latter is raised and contact 26 closed. The leading edge then passes along the upper surface of clamping plate 24 until it engages feeler 29 which is also raised closing contact 27. This completes the circuit 32 causing operation of solenoid 25. This raises clamping plate 24 so that the leading edge of the article is clamped against jaw 23. The remainder of the article is drawn under the clamped leading edge until such time as the trailing edge allows feeler 28 to drop thus breaking the contact 26 and releasing the clamping plate 24. Endless conveyer belts 20 engage and press the folded article against the lower half of the periphery of drum 17. The solenoid 25 may be replaced by electro-pneumatic means and further folding operations may be made on drum 17.

Abstract: 125,689. Babcock & Wilcox, (Bell, J. E.). Feb. 28, 1918. Water-tube boilers; combined with industrial furnaces, kilns, and ovens; generating by indirect contact of heated gases.-In a water-tube boiler heated by the waste gases from an industrial furnace, kiln, or oven, the gases are drawn through the passes among the tubes by a fan so operating that, when the boiler is working at rated capacity, the weight of gas drawn per sq. ft. of average flow area is at least two thousand pounds per hour, and the desired draught is maintained at the outlet from the furnace &c. The Babcock-Wilcox boiler shown has additional rows of tubes and is fitted with vertical baffles 9 arranged so as to give three passes of equal sectional areas. The waste gases enter at the bottom 10 of the front pass and are drawn through the boiler by a fan 13. The inlet 10 may be connected to a by-pass flue leading from the stack of a regenerative open-hearth furnace, and the gases may be discharged through a branch flue 21 opening into the stack, dampers being provided to control the flow of gases into and from the boiler. In a Babcock-Wilcox boiler having 18 transverse rows of tubes and 10 vertical rows and fitted with vertical baffles giving four passes each of 12.2 sq. ft. area, the gases are drawn at a rate of 23,400 lb. per sq. ft. per hour, the draught produced by the fan being 3.1 inches, which, allowing a drop of say 1.32 inches in the boiler, gives a draught of about 1.5 inches at the furnace outlet.

Class 79(3) [Also in Groups XXX and XXXII] A trailer vehicle suspension system (see Group XXXII) includes a pneumatic cushion assembly 15 disposed between the chassis-frame 1 and a member 22 carrying the wheel axles 8, 9. A wire rope tension link 45 cushioned by a rubber buffer 50 is disposed on either side of each cushion assembly 15 at a point midway along its length and is detachable at its lower end. The interior of each cushion assembly is connected by a conduit with an air supply reservoir, Fig. 3 (not shown). A manually operated operable valve is disposed in the conduit either on the trailer vehicle or in the driver's cab on the tractor vehicle, and may be set to connect the cushion assembly 15 with the reservoir, or to atmosphere. Alternatively, it may be set to close the conduit to retain the existing air supply in the cushion assembly. The conduit may also include a pressure gauge between the valve and the interior of the cushion assembly. On disconnecting all the links 45 the pressure gauge gives an indication which is proportional to the load carried by the vehicle and the gauge may be calibrated accordingly. Either end of the member 22 may be secured by a link 70 to the chassis-frame. The wheel adjacent that end of the member 22 may then be lifted off the ground if the cushion assembly is further inflated. Either one wheel, or complete axle, may be lifted by this means, either for the purpose of carrying out repairs or for running on one pair of wheels only. The air supply pressure may be varied to vary the height of the vehicle, for loading and other purposes. Specification 803,752 [Croup XXXII] is referred to.
