Abstract: 1,092,640. Ventilators. WINGARD Ltd. Oct. 20, 1965 [July 25, 1964], No. 30191/64. Heading F4V. A ventilator for a vehicle comprises a cover 19 and a one-piece base member 10 which is moulded in plastics or die-cast in metal and has longitudinally spaced openings 11 and 12. As shown, the base member includes apertured front and rear walls 16, 17 and a partition 13 separating the openings so that when the ventilator is mounted on a vehicle roof air entering through wall 16 is supplied to the vehicle interior through opening 11 and air is extracted from the vehicle through opening 12 and wall 17. The openings 11, 12 are surrounded by cylindrical baffles 14, 15 each of which has a semi-cylindrical cutout in the side remote from the corresponding apertured wall. The base member may also be formed with a semi-cylindrical baffle (Fig. 4, not shown) which deflects air from opening 11 rearwardly into the vehicle. In a modification (Figs. 9 to 13, not shown) the partition and the front and rear apertured walls are formed on the cover which is also provided with flanges arranged to co-operate with the baffles surrounding the openings in the base member. Valve seats (Figs. 14 and 15, not shown) are provided in openings 11, 12 just below the cut-out portions of baffles 14, 15 and an axially movable closed ended cylindrical valve member is arranged in each opening. The cylinder may be moved by a handle (Fig. 14) and provided with a resilient projection, which may engage in any of a number of apertures in a fixed sleeve, or it may be screwed relative to the sleeve by a knob (Fig. 15).

Title: A process for the manufacture of hydrocarbon distillates
IPC: C10G7/00
Filed: 1934-10-25
Abstract: In a process for the fractional distillation of hydrocarbon mixtures of the kind in which the vaporized mixture is introduced between the top and bottom of a fractionating column and the vapours are treated with a counter-current reflux, fractions are drawn off at the top, at the bottom, and at mediary positions, and heat is supplied to the column by reheating the residue at the bottom of the column, further heat is supplied to the column by withdrawing one or more fractions from different levels in the column heating a part or the whole of the withdrawn fraction and returning it to the point in the column from which it was withdrawn.  The supply of heat is regulated so that the boiling ranges of the respective fractions obtained when determined according to the American Society for Testing Materials, (see A.S.T.M. Standards 1933, Part 4, p. 778), do not overlap the boiling ranges of the next higher or lower fractions.

IPC: B27B5/00
Filed: 1924-12-22
Abstract: 241,419. Abraham, D. Dec. 22, 1924. Trenching; cutters.- In a wood-working machine more particularly intended for making staircase stringers, but applicable generally for grooving or like operations, a rotary cutter 30 is carried by rods 20 which slide in a support 15 capable of rocking about a pivot 18 on the head 14 of a column 5 which can be adjusted angularly and vertically in a socket 6, the depth of cut being determined by an adjustable gauge 39 attached to one of the rods 20. The angular adjustment is limited by stops 55 engaging an arm 54 clamped to the column, and the vertical adjustment is effected by means of a hand wheel 11. The support 15 also carries the driving means, such as a. motor 35, connected to the cutter by a belt disposed as shown, to permit the sliding movement of the cutter. The bracket 24 carrying the cutter spindle is connected to its supporting plate 22 by curved slots (not shown) so that a tilting adjustment of the cutter is afforded across the line of feed. The cutter comprises parting blades 45 and clearing blades 46. Adjustable pointers 47 with clamps 49 are mounted on the fence 3 at one side of the table, and a gauge 57 for determining the width of the groove is supported from a bracket 61 and can be turned up out of the way, being held by a spring 64.

Filed: 1974-07-11
Abstract: 1459650 Making desulphurized steel FOSECO INTERNATIONAL Ltd 12 June 1975 [11 July 1974] 30805/74 Heading C7D Sulphur-containing molten iron from a blast furnace is treated with Mg to transfer the S to a slag on the surface of the iron; the iron and the slag are charged to a converter, the slag is treated in the converter to remove S therefrom, and then the iron is converted to steel. Oxygen may be blown through an injection lance in the mouth of the converter into the slag, to convert S in the slag to SO 2  gas, the oxygen blow being arranged to give as high a slag temperature as possible, and preferably not exceeding 5 minutes. The oxygen blow should start before any appreciable conversion of MgS in the slag to CaS, since it is harder to oxidize S from the latter; alternatively any CaO- containing slag may be removed from the molten Fe before treating with Mg.

Light from a lamp 70, Fig. 3, is occluded from a photo-cell 54 by a disk 32 which is rendered opaque by the presence of carbon monoxide in the air, the flow of air through inlet holes in the monitor casing being stimulated by the heat of the lamp and heating resistors 56, 58, which also serve to accelerate the reaction of the disk to the presence of carbon monoxide. The casing, which may be of plastic, includes air flow deflectors to direct air on to the sensitive area of the disk, and partitions which carry electrical components such as switches, transistor amplifiers, and a relay. The casing may carry red and green warning lights, and include an acoustic warning device, and it may be connected by plug and socket cabling to a central point which may provide power supply and give a remote alarm a regulated indication. The disks are replaceable through a slot in the casing.
Patent GB-485000-A (GB)
Title: Manufacture of moulded masses from polyvinyl chloride
IPC: B29C43/00
Filed: 1936-11-12
Abstract: Polyvinyl chloride in the form of powder or as a coarse amorphous mass is moulded under pressure while it is rapidly heated to a temperature above 140 DEG  C. selected according to the degree of polymerization.  For polyvinyl chloride having a polymerization value of K=60 the temperature is at or above 150 DEG  C.  Transparent, flexible sheets can be formed in this way on calender rolls.  Thin sheets may be formed directly or by rolling thicker sheets.  Tubes may be extruded or other articles may be pressed or die-cast by using polyvinyl chloride which has been heated in a kneading machine or worm until it is plastic.  The resulting hot, viscous mass is raised to the required temperature in the moulding machine.  The temperature required rises with the degree of polymerization.  The factor K is given by K=k.103 where k is the "characteristic viscosity" calculated from the formula given in "Cellulose-Chemie," Vol. 13, 1932, page 60, and "Kolloid-Zeitschrift," Vol. 53, page 34.

The member 48 is mounted through the intermediary of bearings 49 in a pylon structure 51 and the blades are further connected to the member 48 by, telescopic members 72, 73. Flapping pivots 57 are provided. In another form the blades 6, Fig. 1, are mounted on stubs or roots 28 journalled in bearings 23 in a hollow hub 13 for pitch-varying movements of the blades ; all the hubs are pivotally engaged by a single centrally-located arm 36 extending in the direction of rotation and arranged so that movements of the arm in planes containing the stub and arm axes do not affect the blade pitch, the end of the arm remote from the stubs being movable at right-angles to the rotational axis in order to effect a cyclical change of blade pitch. The hub 13 is mounted in bearings 12 in a pylon structure 8, is provided with a brake-drum 16, and is driven through gearing 20 and freewheel device 19 in order to initiate rotation. The stubs are connected by members 25, 26 arranged as shown and engaged by four prongs 37 on the member 36. The member 36 has an arcuate bearing on the member 25. Flapping and drag pivots 30, 32 respectively are provided and the blades are further connected to the hub by cables 34. The arm 36 is controlled by the pilot through cables 43 which engage non-rotatable yokes 41.
