Patent GB-940543-A (GB)
Title: Stabilised organic-nitrosoamine-containing compositions
Inventor: DARRALL ROBERT ALFRED
IPC: C08J9/10
Filed: 1961-02-07
Abstract: The invention comprises stabilised organic nitrosoamine-containing compositions characterized in that they contain less than 2% by weight of water and contain as stabiliser an oxide, hydroxide or carbonate of calcium, barium, zinc or magnesium in powder form. Nitrosoamines include those having two or more nitrosoamine groups, e.g. di-N-nitrosopiperazine, trimethylenetrinitrosoamine and, in particular, dinitrosopenta methylane triamine.  The efficiency of the stabiliser, which is most effectively a carbonate, particularly calcium carbonate, increases as its particle size decreases, an average particle size of less than 2m  being preferred. It is also preferable to use 10 to 150%, especially 20 to 150%, by weight of nitrosoamine of the stabilizer and to have less than 1% of water in the composition. The compositions may be prepared by stirring the nitrosoamine with the stabilizer in suspension in water, filtering and drying or by mixing said components in, for example, an homogeniser. It is desirable to include, preferably as 1 to 50% by weight of nitrosoamine, a dedusting agent, e.g. a wax or oil, which may be added to said suspension, preferably in conjunction with a dispersing agent, e.g. a fatty alcohol/ethylene oxide condensation product or a dinaphthylmethane disulphonic acid. The blowing efficiency of the compositions is improved by using finely divided nitrosoamine, prepared, for example, by the addition of a surface active agent prior to nitrosation. The examples illustrate the stabilization of dinitrosopentamethylene tetramine with calcium carbonate, polyisobutylene (dedusting agent) and fatty alcohol/ethylene oxide condensation product.

Filed: 1959-02-10
Abstract: 873,183. Turn-button fasteners. YALE & TOWNE MANUFACTURING CO. Jan. 29, 1960 [Feb. 10, 1959], No. 4567/59. Class 44. A casement window fastener comprises a body part 5, 6 adapted to be mounted adjacent the free edge of the window, a handle 9 angularly movable on the body part, a catch piece 12 angularly movable relative to the body part, driving means connecting the catch piece to the handle for angular movement therewith, keyoperable means for disengaging the driving means, and spring-loaded means 17 for automatically locking the catch piece against angular movement relative to the body part when the driving means is disengaged. As shown, the handle is retained on the body portion 5 by means of a spring clip 10 which surrounds a sleeve 8 formed on the boss of the handle. The catch piece 12 includes a collar 11. A key-operable plug 13 having wheels for engagement with grooves in the boss of the handle 9 is in dog engagement with a cylindrical part 14 of the sleeve 8, the part 14 carrying an eccentric peg 15 which is engaged within a slot or groove formed in a bolt 16 extending laterally through apertures in the sleeve. The arrangement is such that in one angular setting of the plug 13, the outer end of the bolt is flush with the periphery of the sleeve 8 and in another setting enters a hole in the collar 11 and thereby connects the catch piece 12 to the handle 9. The spring- loaded locking means 17 is disposed to be in register with the hole in the collar 11 in the operative position of the catch piece 12, such that when the bolt 16 is withdrawn from the collar by key operation of the plug 13, the locking means 17 automatically enters the hole in the collar to lock the catch piece. A tubular spigot 19 on the rear body portion 6 engages within the sleeve 8, so that notches 20 on the spigot register with recesses 21 of the apertures in the sleeve when the apertures are in register with the locking means 17. A pair of pegs 22 on the bolt 16 prevents the latter being withdrawn until the recesses 21 are in register with the notches 20. Undercut projections 23 on the rear face of the portion 6 slidably engage with guides 24 on a mounting plate 25 which may be secured to a metal window by a screw 28 engaging a stud 29 located in a metal bracket 26 on the window. Alternatively, the plate may be screwed to a wooden window frame. A pin 30 prevents separation of the body part and mounting plate when the catch piece 12 is in the operative position. A spring-loaded peg 31 and a notch in the sleeve 8 facilitates reengagement of the bolt 16 with the hole in the collar 11.

Inventor: HARRY ATKINS
IPC: F41G3/24
Filed: 1916-03-28
Abstract: 103,466. Atkins, H. Jan. 17, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Sights and methods of sighting.-Relates to sighting and aiming devices for use in dropping bombs from aircraft, and comprises an arrangement wherein a binocular telescope 1, 2 is mounted in a gimbal ring 3 having a cross-bar 3a formed as a yoke or socket member 32 supporting a disk 34 integral with a frame 35, 36, in which is mounted a centrifugal governor 40 operated through a flexible shaft 39 from the driving-motor of the aircraft. The slidable end 42 of the governor is connected by a plate 44 to arms 47 on the binoculars, so that the inclination of the sighting-line varies with the driving speed. To correct the action according to the altitude, the " fixed " end of the governor is connected by a plate 50 to a screwed adjusting- spindle 52 actuated by a milled head 53 and carrying upon its other and oppositely threaded end a pointer 54, which moves over an altitude scale 56 on the frame 35. The altitude scale may be adjusted against a second scale 61 to effect a further correction when the aircraft is travelling with a fair wind. For this purpose, the scale 56 is adjusted longitudinally by means of a handoperated pinion carried by the frame 35 and engaging a rack on the underside of the scale. To focus the binoculars, bridge-plates 28, 29 connecting the upper and lower ends are in screwthreaded engagement with oppositely threaded rods 62, 63 mounted in brackets 65 in the body of the binoculars and operated by means of a milled head 66 acting through pinions 69, 70, 71.

Title: Improvements in or relating to pressure reducing valves
IPC: G05D16/06
Filed: 1951-02-26
Abstract: 692,653. Valves. BRITISH OXYGEN CO., Ltd., BLACK, G. D., and WALSH, J. March 13, 1952 [Feb. 26, 1951], No. 4609/51. Class 135 In a pressure-reducing valve of the type in which the valve 9 is actuated by a diaphragm 3, bellows, or piston subject on one face, e.g. the upper, to outlet pressure and, on the other face, to a static loading, as by spring 4, adjustment of the static loading is effected by axial rotation of the tube 18 constituting the inlet for the high-pressure fluid. The spring 4 abuts against a diaphragm-supporting plate 22 and an abutment plate 23 in screwed engagement with the tube 18, and rotation of the tube raises or lowers the plate 23 which is prevented from rotating by the engagement of a rib 24a on the casing in a slot in the plate. A keying disc 43 fitting into a complementary recess in the valve casing and engaging in a slot in the tube 18 prevents inadvertent rotation of the tube. The high pressure fluid enters past a filter 13 and passes from the valve through bores 36 into the outlet chamber on the upper side of the diaphragm. An adjustable stop 37 prevents excessive upward movement of the diaphragm. An extension 25 of the obturator slides on the tube 18, and leakage of fluid past this extension is prevented by a bellows 27 which is secured at its lower end to an annular member and a plate 29, the annular member being sealed to the tube by a U-ring 31 of rubber. Valve outlet pressure is communicated to the interior of the bellows by a passage 32, and the bellows is protected by a skirt 33 depending from extension 25. In a modification, a stuffing box of U-shape replaces the bellows.

Title: Improvements in or relating to self-interrupted electromagnetic devices
IPC: H01H50/82
Filed: 1941-04-08
Abstract: 553,132. Electromagnetic interrupters. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., WOODLAND, C. R., and HOUGHTON, E. I. April 8, 1941, No. 4670. [Class 38 (v)] An electromagnetic device adapted to close a switch a predetermined time after initial energization comprises two centrally pivoted armatures 15, 16 oscillated by a common winding 14, the armature 16 operating the interrupter contacts 36, 37 for the winding while the armature 15 operates a stepping pawl 24 whereby a ratchet disc which has frictionally secured thereto an angularly adjustable cam plate 53 is rotated. The ratchet disc carries a cam 47 which, after initial movement produced by an impulse supplied at 46, allows contacts 50, 51 to close and establish a circuit through the interrupter contacts 36, 37 which maintains operation until the ratchet disc completes one revolution. During this time, at a moment determined by the angular setting of the cam plate 53, contacts 54, 55 are closed to complete a signal or operating circuit 56. The magnetic circuit of the armature 15 is designed so as to be saturated when the armature is attracted so that the operative flux for the armature 16 is substantially unaffected by supply voltage variations, the armature oscillating under all conditions at a frequency determined primarily by its own natural period.

Title: Improvements in and relating to television systems
IPC: H04N3/10
Filed: 1937-02-18
Abstract: 514,880. Television. KRUSEMEIJER, H. J. Feb. 15, 1938, Nos. 4691 and 4692. Void. Convention dates, Feb. 18, 1937, and Jan. 26, 1938. [Classes 40 (iii) and 40 (v)] All the points of a line are transmitted and reproduced simultaneously. At the transmitter, Fig. 1, a line of a film 5 is imaged on a spectrum of mechanical waves 13 in a fluid 31, so that each point of the line is interrupted at a different frequency. A cell 34 receives light from the whole line to produce a complex signal for transmission. The mechanical wave spectrum is produced by a wedge-shaped piezoelectric crystal 19 generating the range of frequencies, which are applied to a "Lummer- Gehrcke" plate 21 to produce spectral diffraction, the waves being rendered parallel by a "lens" 22 and then being applied to a pair of plates 24, 25 vibrated at a high frequency by applying electric oscillations to their electrodes 26, 27, thus modulating each frequency in the spectrum by a higher frequency for a purpose not clear. The waves are then conducted to the tank 32. At the receiver, Fig. 4, the incoming signal is applied to a similar crystal 37 to produce a spectrum of modulated waves, and a linear light beam from 45 is passed through the tank 44 and is deflected over a screen 55 by a mirror drum 54 to reproduce the image. The film is preferably screened and imaged, as in Fig. 7, so that each elemental area is of uniform intensity. The currents from a vertical line are transmitted on a carrier as shown in Fig. 9 and should preferably be converted to the form shown in Fig. 10 before being applied to the crystal. This shaping is performed by the circuit of Fig. 6. The signals are applied to circuit L1C1, amplified by the back-coupled valve 58 and applied to amplifier 73 feeding the crystal electrodes. The minimum carrier amplitudes are isolated at 56 and applied to valve 57 to render it conducting so that condensers C2 and C3 discharge. Condenser C3 controls the deflecting potential applied to plates 60, 61 of a cathode-ray tube 62, so that the cathode-ray beam is deflected to electrode 65 when condenser C3 discharges, thus applying a negative pulse to the grid of valve 58 to render it non-conducting and allow the grid-circuit L1C1 to build-up the maximum amplitude corresponding to the received signal. Simultaneously, the valve 69 is rendered conducting by the pulse from 68 so that resistance R3 is in shunt to R2 thus increasing the anode potential of valve 58. A discharge tube 67 breaks down to short circuit part of the resistance R1 and charge condensers C2, C3, thus deflecting the cathode ray beam to electrode 64 and allowing valve 58 to operate, and also rendering valve 69 non-conductive to reduce'the anode current of valve 58, so that the crystal receives the incoming signal.
