Title: Improvements in or relating to fuses for projectiles
IPC: F42B12/08
Filed: 1924-10-22
Abstract: 246,217. Pantoflicek, B. Oct. 22, 1924. Projectile fuzes. - A fuze operated by the deformation of its nose on impact is given a special configuration or is provided with special means for preventing the action while the projectile penetrates soft protective material but subsequently allowing the fuze to act on impact with a hard target. In the form shown in Fig. 1, the nose 1 projects from a sloping shoulder 2 which, when the projectile strikes soft material, causes this material to crowd round the nose, thereby preventing its deformation. In the modification shown in Fig. 2, the nose 1 is protected during passage through soft material by a surrounding cap 4 which is subsequently blown off by a charge 5 fired by a time fuze before the projectile strikes a hard target. In a further modification, the cap 4 is made in parts bound together by a wire severed at the appointed time, when the parts fail off by centrifugal force.

Title: Film coating apparatus, more especially for producing magnetic sound tracks on cinematographic films
IPC: G11B5/633
Filed: 1955-09-01
Abstract: 813,987. Coating webs. AGFA A.G. Sept. 1, 1955 [Sept. 3, 1954], No. 25191/55. Class 140. An apparatus for applying a stripe of fluid coating material to a film strip comprises a film supporting roller 3 and a nozzle 2 resiliently mounted to contact the film and adjustable so that part 24 of the nozzle orifice 26 contacts the approaching film while the distance of the film withdrawal side of the nozzle from the film can be varied to vary the thickness of the coating. As shown in Fig. 1, a film 23 is passed over guide rollers 4, 5, 6 and over the roller 3 mounted in a plate 11 beneath the coating nozzle 2. The nozzle 2 is mounted in a head 1 clamped in a ring 12, mounted on telescopic arms 13, 14 pivoted at 19 in the plate 11 and adjusted axially of the arms by a knob 16 with a scale 18 through gearing in a housing 17. The head can be rotated about the longitudinal axis of the arm 14 by adjusting a ring 22 with a scale. The knob 16 and ring 22 act as counterweights or the pivot 19 may have a spring for resiliently mounting the head. The head can be moved transversely of the film strip by another telescopic arm and scaled head. The edge of the film is guided by contact with a disc 27; the roller may be slightly conical. Alternatively the film is guided by two spaced rollers 29, 30 contacting the edge of the film and rotated thereby, the rollers being mounted in a disc 33 and the film being slightly compressed transversely by them. The other edge of the strip may pass in a groove between the end of the roller and a ring. The roller has an annular groove 61 to ensure that perforated portions of the film do not touch the rollers. The nozzle is not positioned vertically above the spindle 7 of the roller, so that only the side of the nozzle which the film approaches contacts the film and this side is rounded. The contact pressure of the nozzle is adjusted by the knob 16 and ring 22. The nozzle head, Fig. 3, comprises a member 1 having an internal member 36 with a bore 37 through which passes a pin 38 with a plunger 39 for closing the nozzle aperture. The pin is moved upwardly by the action of a spring 44 to open the nozzle when a head 41 is rotated. The nozzle may have more than one aperture. The head is supplied with magnetite dispersion through an inlet from a reservoir 52 adjustably mounted on a telescopic upright 55, 57. The plate 11 is mounted by a member 49 to slide on a member 51 on a base 50 so that the unit is easily removable. A second unit may be provided to deposit a compensating track along the other edge.

Title: Improvements in and relating to the oxidation of organic compounds
Inventor: WHITFIELD GORDON HOWARD
IPC: C07C51/265
Filed: 1956-08-20
Abstract: The invention comprises a process for the production of benzoic acid by the oxidation of toluene in the presence of up to 10% of its own weight of benzoic acid, or an oxygenated derivative selected from benzoic acid, benzaldehyde, benzyl benzoate, benzyl alcohol or their mixtures, in an amount chemically equivalent to up to 10% of benzoic acid, and as catalyst, of the bromide of at least one metal of variable valence in the liquid phase, and in the absence of other solvents, by means of molecular oxygen or ozone.  The preferred bromides are those of cobalt and manganese, which are preferably used together.  The metal bromides may be introduced as such or produced in situ from e.g. the acetates, naphthenates, Raney-type metal, the carbonyl or oxide, and e.g. bromine, hydrogen bromide or sodium bromide.  The bromine lost during the process may be replaced by introducing more bromine, hydrogen bromide, an alkali metal bromide or a bromo derivative of the aromatic starting material into the reaction mixture.  From 1 to 0.0005 gram atom of total metal per gram mol. of starting material, is preferably used, and the ratio of manganese to cobalt may be from about 2 : 1 to about 9 : 1.  The reaction is preferably carried out by oxidizing the toluene in the presence of at least one organic salt of the metal whereby the oxygenated compound is produced and the oxidation then conducted in the presence of the bromide produced in situ.  The reaction may be conducted at ambient up to 300 DEG  C., and up to 200 atmospheres gauge, the reaction mixture being preferably kept at boiling point, and water and exit gas continuously removed from the mixture.  The reaction may be carried out batchwise or continuously, and in the latter case several oxidation reactors may be arranged in series and the benzoic acid in the last of these purified by distillation or sublimation, any incompletely oxidized fraction being returned to the oxidation vessel.  The molecular oxygen may be used as such or as air or air mixed with inert gases such as nitrogen or carbon dioxide, or the gaseous products of the oxidation or combustion of an organic substance with air.  Examples are given in which benzoic acid, benzyl alcohol, benzaldehyde, and benzyl benzoate are formed. Specifications 804,612, 810,020 and 833,438 are referred to.
