Title: Method and apparatus for forming strip material into tube
Inventor: EDE AINSLEY NEVILLE
IPC: E02F5/10
Filed: 1960-01-11
Abstract: 952,869. Making drainage pipes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 6, 1961 [Jan. 11, 1960; March 4, 1960], Nos. 1019/60[and 7843/60. Heading F2P. A method of forming a tube from two or more lengths of flexible sheet material, e.g. polyvinyl chloride, in the form of strips 38 having integral interlockable tabs 39 and recesses 41 formed along the longitudinal edges thereof, comprises curling the strips about the longitudinal edges thereof in troughed form and joining the curled strips together in side-by-side relationship by introducing the tabs of one edge of one strip into the co-operating recesses of an adjacent edge of another strip to form interlocked longitudinal seams in which the tabs are passed inwardly through the co-operating recesses with respect to the formed tube to lie against the inside surface of the tube. As shown, a vertical feeder conduit 25 and a former tube 26 extending horizontally are mounted behind a mole plough 10 carried by a tractor 14, the conduit carrying reels 32 of continuous strip material which are drawn down the interior of the conduit and around an inclined guide plate 35, rearwardly to the tube 26 and into a die 36, the finished tube then passing through a sleeve 37 and into a tunnel 15 formed by the mole. The die 36 comprises a guide block 43 and a pair of concave sheet metal guide troughs 44, 45, longitudinal slots 46 . . . 49 being formed in diagonally-opposite corners of the block. The slots 47, 48 extend longitudinally parallel to the axis of the block, but the slots 46, 49 extend obliquely to the longitudinal axis so that the pairs of slots 46, 47 and 48, 49 intersect one another. As two strips of material are simultaneously drawn through the die the slots 46, 49 progressively carry the slotted edges of the strips towards the tabbed edges lying in the slots 47, 48 until at the intersections of the slots the tabs 39 of one strip enter the slots 41 of the other strip. The tube thus formed is allowed to expand, due to the resilience of the material, to cylindrical form so that the tabs lie flat against the internal surface of the tube. The die may be modified to form tubes from three strips of material. Specification 851,746 is referred to.

Title: Method of conducting gaseous chemical reactions
Inventor: JACKSON KENNETH
IPC: B01J19/08
Filed: 1959-01-12
Abstract: Chemical reactions are effected in gases at absolute pressures above 40 cms. Hg., e.g. 1 atmosphere or up to 500 atmospheres or higher, by means of an R.F. electrodeless electric discharge, the discharge plasma being confined out of contact with bounding dielectric wall surfaces so that the latter are kept at a moderate temperature; the reaction products are afterwards quenched.  The discharge plasma may be confined by introducing the gases in the form of a jet at an angle or through tangential slots so as to give the gases a helical motion. Alternatively vanes may be provided in the discharge zone or an annular stream of inert or reactant gas may flush the wall surfaces. In another method the discharge is confined by a magnetic field.  The reactions may be carried out in a tube of fused quartz and the tube may be provided with a cooling jacket.  Suitable reactions are the production of nitric, oxide from nitrogen and hydrogen or hydrazine from nitrogen and hydrogen or from ammonia or from ammonia and hydrogen; hydroxylamine from nitrogen, hydrogen and oxygen; and hydrogen cyanide from nitrogen and methane.  Specifications 301,929, 301,930, 635,398, 700,801, 706,036 and 873,090 are referred to.

Title: Improvements in or relating to means or apparatus for improving the durability of glass containers
IPC: C03C15/00
Filed: 1943-01-25
Abstract: 563,091. Photo-electrically controlled glass - treating machines. UNITED GLASS BOTTLE MANUFACTURERS, Ltd., SEDDON, E., and MOORSHEAD, T. C. Jan. 25, 1943, No. 1218. [Class 56] [Also in Group XL] Relates to apparatus for introducing into glass bottles and like containers glass treating materials, such as described in Specifications 531,145 and 556,602. According to the invention, normally inoperative photo-electric means are provided to prevent the delivery of the materials when a bottle is not in the receiving position. In the apparatus shown, the bottles P coming from a glass-forming machine are carried by a belt E with spacing fingers F and pass underneath a shoot A containing the treating materials in tablet form. A disc B with openings C rotates below the shoot A in timed relationship with the belt to extract a tablet from the bottom of the shoot and drop it into the bottle which reaches the correct position under the shoot. According to the invention a lamp K is provided on one side and a photoelectric cell H on the other side ; and the cell is connected to an amplifier G controlling a solenoid M, the core of which is connected bv linkwork I to a shutter J at the bottom of the shoot. The amplifier G is switched off by mechanism L, N controlled by the spacing fingers F of the belt, except when a bottle is due to arrive underneath the shoot ; and when a bottle arrives under the shoot, itobstructs the light from the lamp to the cell and the amplifier remains inactive although now switched on. But if a bottle is missing under the shoot when the belt occupies the position when the amplifier is switched on, the light then received by the cell causes the amplifier G to operate the solenoid M, thereby closing the shutter J. Instead of switching the amplifier G off by the mechanism L, N, the light may be cut off by a shutter controlled by the belt. The temperature of the ware in the region where the material is supplied, cooling may be accomplished by lengthening the conveyer belt, or heating may be effected by heating elements around or in the conveyer base.

Title: Improvements relating to locomotive remote control systems
IPC: B61L3/12
Filed: 1962-01-16
Abstract: 977,504. Remote control of trains. WESTINGHOUSE AIR BRAKE CO. Jan. 16, 1962 [Jan. 25, 1961], No. 1495/62. Heading B7N. In a system for controlling unmanned trains from a remote point, the control commands are transmitted via a communication arrangement comprising, at the control point, a radio transmitter CT which may be modulated by one or more tones produced by the generators TT1- TT7 under the control of push-buttons TAPBRPB and on the locomotive, a carrier receiver CR and a number of modulation tone receivers TR1-TR7, one for each tone, each of which energizes an associated relay R1-R7 on receipt of its modulation tone. Push-button HSCB forms a type of " dead man's handle " control which must be held depressed during the period control is exercised over the train. The push-button energizes tone generator TT3 and via the receiver and modulation tone receiver TR3, relay R3 is energized to hold off a brake application by energizing brake magnet BM. Push-buttons FPB and RPB, which are interlocked so that only one may be depressed at any one time, energize, respectively, relays R6 and R7 and hence forward and reverse relays F and R, respectively, on the locomotive to control its direction of movement. Pushbutton SPB controls a sanding device via relays R5 and SM and push-button BAPB controls a brake application by opening the circuit of brake magnet BM, at back contact a relay R4. Push-buttons TAPB, TRPB energize respectively, via relays R1, R2, the forward stepping winding SADV and reverse stepping winding SRTD of throttle control stepping switch SS, whereby each depression of switch TAPB steps the switch forward one position and each depression of switch TRPB steps it backwards one position. In position 1 of the switch a line contactor relay LC, which prepares the locomotive motors for operation, is energized via a circuit which extends via contacts of relays F and R and bank d of the switch. In positions 2-7, throttle control relays T1-T3 are energized, via switch banks a, b and c, in different combinations to control the speed of the locomotive. In the event that the push-button HSCB is released during movement of the locomotive, the brakes are applied as previously stated and the reverse winding SRTD is energized to step the switch back to its zero position via a circuit which extends via back control a relay R3, self-stepping contact 10 and switch bank e.
