Title: Improvements in shell or like fuses
IPC: F42C3/00
Filed: 1919-09-18
Abstract: 138,049. Jones, G. H. Sept. 18, 1919. Projectile fuses.- Felates to fuses of the kind comprising a tube b containing phosphide of calcium, metallic potassium, or other substance adapted to ignite cn contact with water, and consists mainly (1) in closing the tube by a plug or cap g of easily fusible metal such as an alloy of lead, tin, and bismuth, or of an inflammable material such as parchment, india-rubber, or celluloid, which is melted or ignited by the fire of the propellant charge in the gun; and (2) in immersing the ignitable substance in an oil to protect it from accidental moisture. A grid i is placed under the cap g to retain the ignitible substance in the tube b while allowing the oil to drain off after the cap has been destroyed. The inner end of the tube is closed by plugs h also of readily fusible metal which, when destroyed by the ignition of the substance in the. tube, allow the flash to pass to a detonator or direct to the bursting charge of the projectile. The tube b may be screwed into a socket a, or may be secured therein by a snap fastener. The ignitible substance may be in granular form or moulded into a rod of definite length or compressed or perforated so as, to produce a definite time delay before the explosion of the projectile,

Title: Camera shutter
IPC: G03B9/10
Filed: 1973-05-15
Abstract: 1430104 Camera shutters PHILIPS GLOEILAMPENFABRIEKEN NV 15 May 1973 [18 May 1972] 23040/73 Heading G2A A shutter mechanism for a photographic camera comprises two rotatable shutter members 4, 5 having apertures 7, 8 which, when the members rotate, coincide to expose a photographic film, the members being rotated by a single shaft 14 which is driven by a spring 17 and is only rotatable in one direction, the spring being in a condition of minimum strain when the apertures coincide. Members 4 and 5 are mounted on a hollow shaft 11 and on a shaft 9 coaxial with shaft 11 respectively. These shafts also carry bevel gears 10 and 12 which cooperate with a gear 13 mounted on shaft 14. Shaft 14 carries a ratchet 15 which co-operates with a pawl 19 to prevent clockwise rotation. A spring 17 is connected at one end to a pin 16, eccentrically mounted on ratchet 15, and at the other end to a fixed pin 18. In operation the mechanism is tensioned by rotating shaft 14 by a device (not shown) just past the point where pin 16, shaft 14 and pin 18 (in that order) are colinear. When shaft 14 is released it is rotated rapidly by tensioned spring 17 in the direction indicated and drives members 4 and 5 in opposite directions. The exposure time is determined by the velocities of members 4 and 5 when the apertures 7, 8 overlap. This time may be varied in a further embodiment in which pin 18 is movable so that spring 17 is no longer aligned with points 16, 14, thus varying the force placed on pin 16 and hence the rotational speed of shaft 14.

Patent GB-759834-A (GB)
Title: Improvements in or relating to a method of forming a ferrous metal article
IPC: C22C33/02
Filed: 1951-10-10
Abstract: A method of forming a ferrous metal article of less density than solid metal from oxide containing ferrous material of fine particle size comprises reducing a freely packed mass of the material to form a mass of metal particles at a temperature less than the melting temperature supporting the particles in a shaping structure while heating to a temperature high enough to cause coherence of the particles and form a unitary uncompacted body of finite shape and containing voids.  The particles, e.g. of haematite ore, may all be of a size passing 325 mesh, may be packed into a paper container of cylindrical shape, embedded in a mixture of coke and lime to reduce the oxide, and held at 1950 DEG F. for 30 hours.  Gaseous reducing agents, e.g. carbon monoxide, may be used.  The reducing agent used, the temperature, the time of holding, the average size and the size distribution of the particles have each an effect on the density and carbon content of the article.  Particles having different dimensional changes on heating during reduction may be mixed to compensate for these changes or particles of one kind of dimensional change may be packed with an excess of voids to compensate for the change. Manganese and chromium oxides may be added to form alloys. Specification 759,833 is referred to.

Title: Improvements in and relating to liquid circuit refrigerating plants with cold accumulator reservoir
IPC: F25D16/00
Filed: 1946-08-16
Abstract: 615,037. Refrigerating. TREPAUD, G. J. H. Aug. 16, 1946, No. 24516. Convention date, Jan. 5, 1945. [Class 29] In refrigerating plants having a cold accumulator 7 for dealing with peak loads, valves 10-15 are provided whereby the accumulator can be inserted in the circuit either before or after the cold utilising appliance e.g. a wort cooler 6. During normal working valves 10, 12, 14 are open and valves 11, 13, 15 closed, and brine is forced by a pump 8 from the evaporator 5 to the cold accumulator 7 and thence to the wort cooler, whence it returns to the evaporator, the accumulator absorbing excess cold. When the demand for refrigeration increases the temperatures of the cold accumulator 7 and the wort cooler 6 rise, and when the temperature of the outlet of the coil 6 reaches 0‹C., the highest permissible value, the cold accumulator is at say -8‹C. The valves 10-15 are then reversed, so that the cold accumulator 7 is inserted in the circuit after the wort cooler. The temperature of the cooler 6 then decreases since it is supplied with brine direct from the evaporator 5, and the brine is returned to the evaporator at -8‹C. and leaves it at say -13‹C. The system may continue to operate under the peak load until the temperature at the outlet of the coil 6 again reaches 0‹C. Upon cessation of the peak load the accumulator 7 is cooled again, and when the temperature of the brine at the outlet of the evaporator reaches its allowable lower limit, say -16‹C., the valves arc reversed again, and the cycle may be repeated. The valves may be automatically operated by a thermostat in the cold accumulator tank. Specification 457,732 is referred to.
