Title: Improvements in or relating to apparatus for covering boxes
IPC: B31B15/00
Filed: 1921-03-29
Abstract: 178,698. Stokes & Smith Co., and Burlton, E. T. March 29, 1921. Machines for covering boxes.-Relates to means for turning over and tucking in, by means of one set of operating devices, the covering flaps of the vertical edges that occur in drop-front and other boxes, and in box lids having fewer than four sides. The Figure shows in plan that half of the machine operating upon one end of the box or lid. The turning-over is effected by fingers E mounted on blocks e slidable in slots formed in a bar F carried by a depending extension B<1> of a slide B which carries operative parts of the ordinary covering mechanism. The blocks e are urged inwardly by springs e<2>, but in the position shown (by the full lines) are prevented from moving by stationary wedge pieces C yieldingly mounted on brackets c adjustable on the slide bar D which itself is also carried by fittings on the depending extension B<1>. The bar F can, as indicated by the dotted lines, be moved forwardly, this movement being derived by means of links and a bell-crank lever from reciprocating motion given to a vertical rod H. Assuming the apparatus to be in the position shown in full lines, the fingers E lie just outside the small flaps g, which have to be turned over the vertical edges of a box or box lid. The first forward movement of bar F releases the blocks e from the wedges and the fingers E therefore approach each other as they advance forward, consequently the flaps g become folded into the positions indicated on the left-hand side of the figure. A further advance of bar F into the second position shown in dotted lines causes the completion of the tucking-in operation as is indicated on the right-hand side of the figure. Specifications 19966/01, 19967/01, and 10902/13 are referred to.

Title: Improvements in or relating to semiconductor devices
Inventor: COLSON IAN DOUGLAS
IPC: H01L23/40
Filed: 1957-03-22
Abstract: 826,058. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. March 11, 1958 [March 22, 1957], No. 9416/57. Class 37. A semi-conductor device, the electrode assembly of which is enclosed in a metal envelope, is associated with a metal clamp, part of which is adapted to be secured to a chassis or cooling plate, and with a resilient electrically insulating member which is trapped between part of the envelope and another part of the clamp so that the envelope is held by but insulated from the clamp. In the Fig. 2 embodiment a germanium or silicon PNP junction transistor 2 is mounted in a copper envelope consisting of two cups 3, 4, the flanges of which have been thermetically-sealed together by coldwelding in dry nitrogen. The envelope fits in an anodized aluminium cup 10 which insulates the envelope from the metal chassis 13 to which it is clamped. The envelope is clamped to the chassis by a flanged pressed steel sleeve 12 which fits over an annular member of synthetic rubber (a silicone rubber if the transistor is of silicon). Wires making connection with the electrodes of the transistor, two of which pass through glass beads 6 and the other of which, 9, is mounted on the envelope pass through aligned apertures in cup 10 and the chassis. An alternative embodiment, Fig. 4, differs in having a clamping member 37 consisting of a flanged pressed steel cup which is insulated from the metal envelope by insulating disc 36, e.g. of phenol-formaldehyde resin. In this case all the wires from the transistor emerge from the envelope through a single glass bead 30. Heat dissipation to the chassis may be improved by dispensing with the cup 10 where it is unnecessary to insulate the envelope from the chassis. Specification 817,636, [Group XXIII], is referred to.

Title: Improvements relating to fire extinguishers
IPC: A62C13/00

Abstract: 375,844. Fire-extinguishers. MINIMAX, Ltd., Feltham, Middlesex, and GREGORY, G. A., Primrose Cottage, Langley Road, Slough, Buckinghamshire. March 28, 1931, Nos. 9517 and 9518. [Class 47 (ii).] In an inversion extincteur of the kind in which a spindle carrying a valve for closing the inner vessel is provided also with means for obturating the discharge outlet of the extinguisher, the valve e is carried by a pin k fixed to the spindle f, the latter being of such diameter as to close completely the outlet c<5> to the nozzle g when the valve e is closed. In a modification, the lower end of the spindle carrying the valve is reduced. A. cage l limits the upward movement of the spindle. The latter is connected by a pin h<2> and slot f<1> to a cap h associated with springs i, j. The spindle is held in the closed position by a bayonet joint h<1>, and is packed by packing f<2> compressed by the spring j. In another modification, the lower end of the spindle is hollow or perforated, and adapted to open communication with the nozzle g only when the valve e is opened. In another modification, the cap h has one or more cam slots or surfaces co-operating with pins or surfaces on the cover of the extinguisher, whereby rotation of the cap causes axial movement of the spindle. The slots or surfaces are interrupted at points to cause locking of the cap in the extreme positions of the spindle.

Abstract: 274,177. Calder, W. April 12, 1926. Combined with other apparatus; driving.- Apparatus for purifying liquids or for separating liquids such as water and oil comprises a strainer and a centrifugal drum, rotated by a turbine or like wheel driven by the flow of liquid under treatment, the turbine or wheel being arranged so that it can be moved out of the driving portion. A valve G directs the liquid either through a strainer B or straight to the pipe C leading to a turbine D which is connected by gearing to a centrifugal drum E.

The drum has a central outlet and one or more side outlets controlled respectively by valves I', I. The turbine can be lowered by a screw K to an inoperative position in which the liquid passes over without driving it.

Patent GB-921631-A (GB)
Title: Method of producing gasoline having improved distribution of anti-knock capability
IPC: C10L1/06
Filed: 1960-03-18
Abstract: Gasoline having an octane distribution capable of reducing knock due to manifold distillation is produced from straight run naphtha by reforming a light fraction of the whole straight run naphtha together with part of a heavier fraction to raise the octane number to a predetermined value and thereafter blending the reformed product with a predetermined amount of unreformed heavy fraction of the straight run naphtha to produce a blend having the desired octane distribution.  In one embodiment of the invention a straight run gasoline is fractionated into at least two fractions, the first fraction having an end boiling point of about 280 DEG F. and the second fraction having an end boiling point of not more than about 380 DEG F., all of the first fraction and part of the second fraction are reformed to obtain a reformate having an octane rating higher than the required rating of the finished gasoline, and this reformate is then mixed with the balance of the second fraction to provide a blend having the required octane rating.  The compositions of the invention may contain tetraethyl lead.

Abstract: 590,406. Filler blocks. GILSON, P. C. J. April 20, 1945, No. 9969. Convention date, May 15, 1944. [Class 20 (iv)] Reinforced beams, slabs, floors &c. are built up of hollow bricks having a trapezoidal cross section A, B, C, D, Fig. 1, and provided with air cells 8 and 9 interposed between the lower face D, C of the brick and adjacent grooves or channels 6 and 7 which are adapted to take reinforced cement so that, after assembly into a beam &c. the cement G coating the longitudinal reinforcing irons F is substantially prevented from reaching the surface XX, Fig. 2, which has over practically its whole extent an overlying insulating air cushion provided by the air cells 1, 2, 8 and 9. This maintains a uniform temperature over the surface and so tends to prevent deposition of moisture and dust on it. All the channels 4, 5, 6 and 7 open upwardly so that with the bricks resting on their lower face CD the reinforcing irons F with their covering cement G, can be placed in position in a single operation. The thickness of the walls e is uniform throughout its extent thus preventing internal tension within the brick. The beams may be connected by wire yokes I twisted together. In a modification, alternate bricks are inverted and are supported by the adjacent brick, the channels in them being left unfilled.
