Title: Process for the production of coloured photographic pictures
IPC: G03C7/20
Filed: 1932-02-01
Abstract: 397,884. Colour photography. DRKOPP-WERKE AKT.-GES., Bielefeld, Germany. Feb. 1, 1932, No. 2993. Convention date, Feb. 9, 1931. [Class 98 (ii).] In the production of colour photographs by printing from two complementary negatives on to opposite sides of a film coated on both sides, the negatives are obtained by single exposure of a bipack and are accurately focused and brought into register on a ground glass screen and copied by projection on the doublecoated film. Weak diapositives are made which are weakly coloured in complementary colours and provided with a reflecting support for viewing. To produce three-colour pictures, the coloured diapositive is bathed with a chromate solution and exposed from one side, the unhardened portions on the other side being then coloured with an acid pigment. The negatives are produced on a bipack comprising a front plate mainly sensitive to green and slightly sensitive to blue and a rear, redsensitive plate which may be partly sensitive to green, an orange filter being placed between the plates or coated on the rear of the front plate. A yellow filter dye is added to the front emulsion, or exposure is made through a yellow filter. The two negatives are each mounted in a projection apparatus and focused and registered on opposite sides of a ground glass screen, registration being facilitated by projection through red and green filters. When registered, the screen is replaced by a doublecoated film having an intermediate screening layer which is removed in the developer. The exposed film is developed in a hardening developer, e.g. pyrocatechin without sulphite, mordanted in a permanganate bath, and coloured by suitable basic pigments, e.g. pyronin 6 for the red side and thionin blue for the blue. After clearing in a bath of potassium metabisulphite, the picture is washed for a few minutes in a bath of ammonium chromate, dried, and exposed to strong light from the red side ; a yellow acid dye is then washed into the unhardened portions of the blue side. The finished film is mounted on white paper or is coated on the rear side with a white pigment which may be lightly coloured with blue or yellow to obtain different tone effects.

Title: Mechanical percussion fuze
IPC: F42C15/24
Filed: 1960-01-28
Abstract: 931,449. Ammunition fuzes. H. JUNGHANS, and JUNGHANS A.G. GEB. Jan. 28, 1960 [Jan. 30, 1959], No. 3168/60. Class 9 (1). A mechanical impact fuze for unrifled rocket projectiles, in which a safety device consists of two inertia weights 21, 22 linked by a bellcrank lever 57 between them, pivoted at 56, is characterized in that the safety device and an escapement mechanism are arranged in a boxtype mounting frame and inserted into the fuze body 10 from the rear. The escapement mechanism (Fig. 3, not shown), operates as in Specification 858,516. The weights 22 and 21 are guided by a screw 24 in a slot 23 and an axiallyparallel pin (not shown) respectively. A primer carrier plug 59 is inserted from the rear into the fuze bore and serves as a rear abutment for a compression spring 58, applying a forward load to the mounting frame, and is itself held by an internally and externally-threaded annular nut 61 into which a detonator carrier plug 62 is screwed. In operation, as the projectile accelerates, the weight 22 is displaced rearwardly against the delaying action of the escapement and frees the bell-crank lever, thus allowing the weight 21 to be rearwardly displaced by inertia. The pin 41 then frees a detent spring 38 so that it engages a rear annular groove 39<SP>1</SP> on a safety-pin 36 and thereby recouples the pin to the weight 21 for forward movement. When the weight 21 is displaced forwardly again by a spring 55, after completion of the projectile acceleration, the rear end of the pin 36 is released from a pivoted member 30 which is sprung clear from the passage for a striker pin.

Title: Improvements in or relating to rendering carbon monoxide-containing gases non-toxic
IPC: C10K3/04
Filed: 1951-02-09
Abstract: In a process for detoxicating fuel gases containing carbon monoxide, the gases are first purified by removing hydrogen sulphide, organic sulphur compounds and resin-forming substances and are then passed over a cobalt catalyst at between 120-180 DEG  C., preferably between 120-160 DEG  C., and at a space velocity or a contact time such as will restrict the formation of methane whereby normally solid reaction products, such as paraffin wax, accumulate in the catalyst and are extracted from time to time with a solvent, normally liquid products which comprise an oil with a high boiling point are separated by condensation, and highly volatile reaction products are removed from the detoxicated gases by passing them through a vessel containing adsorbent material.  The process may be carried out at elevated pressures and the gases may be passed over the catalyst in a series of steps.  In an example a gas was passed over the catalyst at 140 DEG  C. and a velocity of 12.3 litres per hour per 100 gms. of catalyst.
