Title: Improvements in or relating to means for controlling and synchronising firing of machine and other guns between aircraft propeller blades
IPC: F41A19/05
Filed: 1934-04-04
Abstract: 436,291. Automatic guns. SOKAL, S., 1, Great James Street, Bedford Row, London.-(CeskÓ Zbrojovkß Akciovß Spolecnost v Praze; 31, VßclavskÚ nßm., Prague) April 4, 1934, No. 10254. [Class 92 (ii)] Relates to synchronized firing mechanisms for automatic guns firing between the blades of aircraft propellers, and consists of a safetydevice, interposed between the trigger-actuating rod or slide of the trigger-motor and the trigger, to interrupt the firing except when the breech is closed and locked. The safety-device is carried by a part of the gun action that is controlled by the synchronizing rod or slide. The invention is shown applied to the trigger mechanism of a gun of the Maxim type. The usual trigger 1 is fitted with a spring- controlled pin 3 which in the firing position enters a gap x, Fig. 1, between a slide 2 reciprocated by the trigger-motor (not shown), and a spring-controlled slide 5. When the breechblock 8 moves rearwards for opening, the pin 3 presses back the slide 5 which, however, returns to its forward position when the pin 3 is lowered by engagement with a fixed ramp 7, and then holds the pin depressed while the breech-block 8 moves forwards again to the closed and locked position, Fig. 4. The pin 3 can thereafter only re-enter the gap when the slide 2 has moved to the right from the position shown in Fig. 4, ready for its next firing stroke. The spring plunger 9 controlling the trigger 1 also serves to retain the pin 3 against removal.

Title: Improvements in or relating to polymeric materials
IPC: C08G18/76
Filed: 1957-03-29
Abstract: The invention comprises a polymer having the recurring unit <FORM:0857600/IV(a)/1> wherein X is a bivalent aromatic radical wherein each of those nuclear carbon atoms adjacent to the points of attachment of the nitrogen atoms bears a lower alkyl group, R is an organic radical, Z is -O-, -S-, or -NR11- (R11 being a hydrogen atom or a hydrocarbon radical which in combination with all or part of -R- may form a ring), Q is a divalent chain extending radical, and m is a small whole number.  It also comprises a process for the production of an elastomeric polymer, which comprises first reacting an aromatic diisocyanate, having lower alkyl groups attached to nuclear carbon atoms adjacent to the carbon atoms bearing isocyanate groups, with a polyfunctional active-hydrogencontaining polymer having a molecular weight between 700 and 8,000 and melting below 60 DEG C. so as to form an isocyanate-terminated polymer and then reacting this isocyanate-terminated polymer with a difunctional active-hydrogencontaining compound chosen so that it, in an independent reaction with the aromatic diisocyanate of the first step, produces a polymer melting above 200 DEG C. when of fibre-forming molecular weight.  The radical R may be a divalent aliphatic or aromatic radical.  It may contain repeating units, being, for example, a polyalkylene glycol, polyurea, polythiourea, polyureylene, polyurethane, polyamide, polysulphonamide or polyester radical.  Radical X is preferably a 2, 4, 6-lower alkyl-1, 3 phenylene radical.  It may also be 2, 4, 5, 6-lower alkyl-1, 3-phenylene or 2, 3, 5, 6 lower alkyl 1, 4-phenylene or may have the formula:  <FORM:0857600/IV(a)/2> in which A is a lower alkyl group and Y is one of the radicals -SO-, -SO2-, -CH2-, -CHR1-, -CR1R1-, -NR1-, -PR1-, -O- and -S-, R1 being a monovalent hydrocarbon radical. The polyfunctional compounds may contain as terminal radicals possessing active hydrogen those of the formula -OH, -NH2, -SH, -COOH, -CONH2, -CSNH2, -SO2NH2 and -SO2OH.  Specified chainextenders (which with the specified diisocyanates form a polymer of melting point above 200 DEG C. when the molecular weight is in the fibre-forming range) are ethylenediamine, bis(p-aminophenyl) methane, bis(4-aminocyclohexyl)methane and 2, 5-dimethyl-piperazine.  The products are useful in the preparation of fibres, for example by dryspinning from dimethylformamide.  In a typical Example (1) a "trimer" from 2 mols of 2, 4-tolylene diisocyanate and 3 mols of poly (tetramethylene ether glycol) is reacted with 2, 4, 6-trimethyl-1, 3-phenylene diisocyanate.  The isocyanate group-terminated product is reacted with hydrazine hydrate in dimethylacetamide and the solution is dry spun into fibres.  Reference has been directed by the Comptroller to Specification 779,806.

Abstract: 726,453. Stretchbending; dies. LALLI, R. A. April 16, 1953 [May 15, 1952], No. 10485/53. Classes 83 (2) and 83 (4). A sheet-metal die for stretch forming sheetmetal parts comprises a die plate of sheet metal having an upper contoured face conforming to the shape of the piece to be formed thereon and a supporting box frame extending below the plate and secured to the edge portion thereof. A sheet-steel die plate 12 hammered to the required shape is secured at the edge, e.g. by spot welding, to a sheet-metal box frame 14 which may be lined with insulating material and have electric heating units 20 secured, either fixedly or adjustably, therein. For cold working, however, the box frame 14 may be filled with high compression concrete. In operation a metal sheet 31 to be formed is positioned over the die plate 12 and held at one end of the die by a clamp 23 and at the other end by a clamp 24. In the embodiment of Fig. 2 the clamp 23 is fixed and the clamp 24 is carried by a pivoted lever 25, moved to stretch the sheet 31 by a hydraulic piston 27 actuated by a hand pump. In the embodiment of Fig. 4 the clamps 23, 24 are carried by a transverse arm 32 moved down by the piston 27 against springs 33. Heat lamps 21, Fig. 2, may be set up to heat the sheet 31 in addition to the provision of the internal heating units 20. A suitable lubricant may be applied to the die-plate 12. A magnesium sheet 31 is heated to about 350‹ F. for the stretch-forming.

The article is finished during a single rotation of the rolls. Each roll is formed with circumferential grooves i, i<1>, j<1>, j<2>, Fig. 5, all starting at the same level at the bottom of the transverse notch k. The parts g, Fig. 2, are rolled with a taper. Rollers x, x may be arranged at each side of the bloom to keep it in position. In a modification, the rolls may be replaced by platens similarly grooved.

Title: Apparatus for winding a length of flexible material
Inventor: REID ERIC WILLIAM
IPC: B65H23/195
Filed: 1961-03-22
Abstract: 932,972. Web-winding apparatus. KEELAVITE HYDRAULICS Ltd. May 15, 1962 [March 22, 1961], No. 10515/61. Class 100 (1). A web-winding apparatus comprises a winding drum 5 driven through transmission mechanism 6 from a displacement - type hydraulic motor 4, a pump 1 supplying working liquid to the motor 4 through a delivery passage 3, a main valve 19 controlling the pressure in the passage 3, and a relief valve 30 which determines the pressure maintained by the main valve 19, the opening pressure of the valve 30 being controlled by a loaded floating-roller 10 engaging a bight 7a in the web 7 so that the torque exerted by the motor 4 varies with the web tension. The main valve 19 includes a piston 18 acted upon by a spring 26 tending to move the piston to a position wherein a part 20 thereof closes a port 22, and subjected at its ends to hydraulic pressure in chambers 23a, 24a. The chamber 23a has uninterrupted access to the pressure in the passage 3 through a passage 27 in the piston 18, whereas the chamber 24a is connected to the passage 3 through a restricted passage 28. The chamber 24a is also connected by a passage 29 with the valve 30. An outlet chamber 21 above the port 22 in the valve 19 communicates with the reservoir by a passage 21a. The loading spring 32 for the valve 30 bears at one end against an abutment 33 on a rod 17 connected to a lever 11 carrying the roller 10, so that movement of the roller caused by variations in web tension causes corresponding variations in the pressure of the spring and in the pressure at which the valve 30 opens. Normally the valve 18 will not be in its closed position but will be maintained in a position such that the pressure in the passage 3 is equivalent to that at which the valve 30 opens. Variation in the latter pressure due to movements of the roller 10 causes variation of the pressure in the chamber 24a and movement of the valve 18 so as to effect corresponding changes in the pressure in the passage 3 and in the torque exerted by the motor 4. The lever 11 is connected to a dash-pot 16 and may be loaded by weights 13, springs, or fluid-pressure piston and cylinder assemblies. An hydraulic accumulator 34 is connected to the passage 29 to prevent sudden movements of the piston 18 which might be caused by sudden movements of the roller 10. Specification 822,803 is referred to in the Provisional Specification.
