Title: Film production
Inventor: ADAMS JOHN FRANCIS EDWARD
IPC: B29C55/28
Filed: 1956-05-15
Abstract: <PICT:0812387/IV (a)/1> <PICT:0812387/IV (a)/2> A film of organic thermoplastic material that has been formed by extruding the material in tubular form, stretched by means of fluid pressure held within a section of the tubing, and thereafter reduced to a substantially flattened state, is treated to remove sag or creases by subjecting the film while held under tension in a substantially flattened state to a heat treatment sufficient to cause shrinkage of the film in the relaxed state. Heat treatment may be applied before winding, or during a rewinding process, and the film may be in a substantially flattened tubular form (see Fig. 2) or may be slit to form one or more lengths of flat film, as in Fig. 1.  As shown, film 1 is held inflated between pairs of nip rolls 2, 3 and progressively flattened between one or two series of guide rollers 4, 9 respectively.  Heat is applied by heaters 7 to the flattened tubular film in Fig. 2 or by heaters 7 and reflectors 8 to the two lengths of film 1a, 1b in Fig. 1, before the film passes to wind-up rollers 6.  Where heat treatment is applied to the film in tubular form, the distance apart of the flattened tube walls is preferably no more than one tenth of the length of the major diameter of the film in this region.  The film may be made of polythene, terephthalic acid linear polyesters, especially polyethylene terephthalate, vinyl polymers, for example polystyrene, polyvinyl chloride, and vinyl chloride/vinylidene chloride polymers, thermoplastic cellulose esters, or rubber hydrochloride.  Preferably, heat treatment is applied by means of radiant or infra-red heaters immediately before the film is wound, and during treatment the film may be held under sufficient tension to prevent substantial overall shrinkage.

Title: Chemical process for the production of esters of carbamic and carbonic acids
IPC: C07F5/00
Filed: 1958-05-12
Abstract: Esters of carbamic and carbonic acids are prepared by bringing a urea containing the group -CO-NH2 into reaction contact with a saturated monohydric alcohol and a source of boron trifluoride at a temperature above about 60 DEG  C.  Carbonic esters are also prepared using an alkyl or cycloalkyl carbamate in place of the urea.  Sources of boron trifluoride include BF3 itself, monoamino boron trifluoride (NH3. BF3), ammonium flouborate, urea.  BF3 complexes and complexes of BF3 and an oxygen containing aliphatic compound such as an ether, carboxylic ester or carboxylic acid.  Excess alcohol is generally used as solvent.  Elevated pressures may be used.  The product may be recovered by filtering off the amino BF3 complex formed and distilling excess alcohol or by extracting with benzene.  The reaction may be carried out in a continuous manner. Suitable ureas for starting materials include urea itself, alkyl urea, cycloalkyl ureas, aryl ureas and chloroaryl ureas.  The alcohol may be an alkanol or cycloalkanol.

Generating combustion products under pressure.-Apparatus for supplying jets of combustion-products at high speed and at frequent intervals to operate a turbine or for other purposes comprises a cylinder 1 having a piston movable therein and cast with two lateral cylinders 2. The piston has two heads 3, 4 and carries a cross-bar 5 movable in recesses 6 in the walls of the cylinder 1. The cylinders 2 have pistons 7 and are in free communication with a reservoir 8, which communicates with the lower end 10 of the cylinder 1 by a spring-pressed valve 12, and with the upper end 17 by pipes 22, 21 and valves 20. A neck 23 for the discharge of gas is closed by a valve 24 slidable in a cut-out portion of the piston head 3. When the head 3 is at the upper end of its stroke, the chamber 17 is filled with carburetted gas under pressure. At this point the cross-bar 5 is adapted to close the ignition circuit through a strip 29, when a spark from the plug 18 explodes the mixture. As the piston descends, a ring 27 on the head 3 opens the valve 24, liberating a jet of gas, and at the same time the fresh gas drawn into the chamber 10 through the neck 14 and valve 15 during the up-stroke is forced into the reservoir 8, refilling the chamber 17. When the pressure in the reservoir 8 is sufficiently high, the pistons 7 are forced up, engaging the cross-bar 5 and recommencing the cycle.

Filed: 1937-06-04
Abstract: 482,927. Aerial bombs. HULSWIT, J. P. June 4, 1937, No. 15537. Convention date, June 5, 1936. [Classes 9 (i) and 9 (ii)] A bomb device adapted to be dropped from an aircraft on to water-borne targets, comprises a carrier in which a plurality of bombs are maintained in a substantially vertical position during descent and means co-operating with the water for turning each bomb into a substantially horizontal position almost immediately upon impact of the carrier with the surface of the water. As shown in Fig. 1, the bomb carrier 10 comprises a shaft 12 provided with rudders 13 and a circular member 14 to which the tails 15 of the bombs 11 are releasably secured. Member 14 is formed with a plurality of radial grooves 16, Fig. 7, and pins 17 bridging these grooves are adapted to be positioned in slots 18 in the tails of the bombs. Each tail 15 is formed with a curved cam surface 19, the lower part of which rests on a solid bottom 20 of the member 14. Each bomb is formed with laterally extending wings 21 and with a downwardly extending fin 22 which is provided with a projection 23 adapted to be received within an opening in a disc 25 slidably mounted on the shaft 12. This disc normally rests on a head 26 secured to the lower end of the shaft, a spring 27 being arranged between the disc and collar 28 on the shaft. When the device is dropped from an aircraft, impact of disc 25 with the water causes it to move upwardly against the action of spring 27 thus releasing the projections 23. The bombs are then free to pivot about the pins 17 so as to cause the upper part of cam surface 19 of each bomb to contact with the inner wall of its groove 16 in member 14, with the result that the bombs are forced away from the carrier so that the pins 17 move out of slots 18 and the bombs are completely released. Each bomb is provided with a self-contained power plant which is connected to drive one or. more propellers 30 and operation of which is initiated, when pin 17 moves out of slot 18, by movement of a rod or cable 31 connected to a pivoted bell-crank lever 33, the arm 35 of which normally extends across the open end of slot 18. Alternatively, if it is desired to initiate operation of the power plant so that the propellers will be rotating before they are submerged, the controls may be arranged to be operated by the upward movement of disc 25, Figs. 10-12 (not shown).

A mono-energetic charged particle beam is obtained from a cyclotron by positioning across the path of the beam a diaphragm 4 having a narrow slot with its axis extending radially, such that the only electrons capable of passing through the slot are those emitted from the source during that short portion of each cycle for which the axial focusing action produces an image point at the slot, together with those electrons, regardless of phase, which are emitted from the source in a direction lying in the median plane, i.e. the central plane intermediate the two faces of each Dee, in which plane the slot is situated. The latter electrons are removed by positioning a graphite target 5, of a size comparable with that of the slot, radially across the path of the beam at a point along the path between the source and the diaphragm. If the charged particle source of the cyclotron is such as to produce a parallel beam, it is arranged so as to inject the beam at an angle to the median plane.
