Title: Improvements in cable projectiles with parachute, to be fired against aircraft
IPC: F42B10/56
Filed: 1928-11-30
Abstract: 321,083. Locori, P. Nov. 30, 1928. Projectiles. - Relates to projectiles for use against aircraft and containing a parachute in a chamber 13 behind a chamber containing a cable 6, the cable and parachute being expelled by a charge 25 when this is ignited by a time fuze screwed to the nose of the projectile, after which the cable extends and is supported in the air by the parachute According to the invention, (1) the cable 6 is repeatedly folded upon itself longitudinally to form a bundle from which the ends emerge axially, the front end being fastened to the base of the charge casing 3 and the other end being fastened to a bolt 9 to which are attached the eyes 12 of the parachute; (2) the charge casing 3 has flexible walls 29 which prevent leakage of the gases of explosion of the charge 25; and (3) the base plug 15. which is conical and extends to within the driving band 18 to strengthen the shell there, is fitted with a disc 30 pivoted laterally at 31, so that when the base plug is expelled the disc 30 swings out by centrifugal force, and causes the base plug to be displaced laterally out of the way of the parachute. The weight of the pivot pin 31 is balanced by a plug 32 of heavier material at the opposite end of the disc. The expelling pressure is transmitted from the charge casing 3 to the base plug 15 by split cylinders 7, 14 embracing the cable and parachute respectively, and separated by a split disc 8, through which the bolt 9 passes. The base piece is normally held in place by shear pins 17 of copper.

Abstract: 394,684. Making battery cups. SEITZ, F., Gieselwerder-on-Weser, Germany. Dec. 30, 1931, No. 35955. [Classes 83 (ii) and 83 (iv).] Curving; shearing-adjuncts.-A machine for making the shells of battery cups &c. from sheet metal, such as zinc, severed from a travelling web and fed to a bending mandrel consists of a plate rocked on the main shaft by worm gear and a curved arm carrying at its free end a continuously rotated mandrel and having also thereon means for actuating the severing blade, blank feeder and a stripper. The metal strip 27 is fed by a rubber roller 26 rotated by belt gear from a motor or belt driven main shaft 2 against a stop 32 and a length 18 severed by a pivoted blade 24 operated by a plate 4 pivoted on the main shaft. The roll shaft 30 at one end is under the control of a spring 31 through lever 35. The plate, which carries a curved arm 8 engaged by an eccentric pin 10 on a disc rotated by worm gear 9 and belt gear from the main shaft so as to rock it, has on its face end a continuously rotated mandrel shaft 5 carrying a mandrel 12 on which the blank is bent. On raising the plate, a spring-returned feed bar 16, connected to the arm 8 by a rope 15, is operated to push the blank over a continuously driven roll 14 and an idle roll 13. The blank is held on the rolls by a curved member 20 secured to a blade spring 19. On lowering the plate a fresh blank is cut and the roll 14 and mandrel 12 co-operate to bend the previous blank. The completed shell is stripped from the mandrel by a bell-crank lever 21 pivoted on an arm 211 secured to the plate and connected by a cord to the bar 16, when the plate is again raised. The shells are received into a receptacle, preferably after passing through a counting mechanism. The mandrel and curved arm 8 may be extended and other sets of feed members and rolls provided so that two or more blanks may be bent simultaneously. The mandrel shaft may also be raised by a pedal.

[Class 40 (i)] In a system for indicating or recording electrically the variations of a quantity such as liquid levels, the quantity operates through gearing the planet wheels of a differential gear, the sun-wheels of which are adapted for rotation in opposite directions so as to control impulse transmitting mechanisms. Each sun-wheel has pins, such as 20, co-operating with a set of tumbling weights 21 which when raised by the pins fall past their dead centres and operate contacts such as 22 to transmit an impulse to the indicator. The impulse transmitters are connected to a relay which selects one or other of two stepping magnets in the indicator in accordance with the transmitter in use. Provision is made in the indicator for recording the signals. The stepping magnets operate the sun-wheels of a differential mechanism, the planet wheels of which control the pointer. Provision also is made for the manual operation of the stepping mechanism in order that adjustment of the pointer may be made. A second signal transmission system comprising a tapped resistance rotatable by the quantity to be indicated and included in the circuit of a voltmeter is provided so that the signals may be verified at any moment.

[Also in Division F2] A screw-on throwaway oil filter comprises a cylindrical metal casing 1, a filter cartridge therein, a thin metal closure member 4 having a central opening with a plurality of oil inlet ports 15 therearound, and a threaded bushing 10 secured to the inner edge of the member 4 for screwing the filter on to an engine block 19. The member 4 forms a pressure-compensating diaphragm spring and comprises radial corrugations, one of which, 7, forms a seal, through a gasket 13, with. the engine block. Member 4 is stamped from sheet metal to form an inherently smooth annular surface between tension annulus 7 and compression band 8, and an anti-drainback valve 20 comprising a disc of soft rubber or other elastically deformable non-metallic material is positioned over said member, across the oil inlets 15, seated at its outer edge on the annular surface and pivotable about its inner edge. In operation, the oil pressure opens valve 20, and oil flows through the filter element 22, and returns to the engine through passage 16. When the oil viscosity is abnormally high or if the filter clogs, a by-pass valve 27 opens to permit oil to pass through the casing without filtration. Should the oil pressure within the casing become excessive due to malfunction of the oil-pressure-regulating valve of the engine, compression band 8 moves upwards slightly under the hydraulic pressure, gasket 13 is unsealed from gasket seat 18, venting oil to atmosphere, and the spring action of the conical wall 9 returns the gasket to its seat to effect resealing as soon as the pressure drops to a safe value. The filter cartridge 22 may be a pleated paper element, or a depth type element formed by packed fibrous material or other filter medium.

Abstract: 995,143. Hot-water boilers. E. FEHR. Oct. 12, 1961 [March 17, 1961], No. 36621/61. Heading F4A. A central heating boiler B is divided by a horizontal partition P into an upper part within which is a domestic supply hot water tank I and a lower part surrounding the fire chamber, two pipes passing through the partition, one, Ri, carrying heating water from the lower boiler part up through the tank I to sweep over the top of the tank and down its outer surface to return to the lower boiler part through the second pipe R. The central heating system is supplied through a pipe F, and circulation is maintained by a pump (not shown) in a return line Rr which discharges into the pipe R through an injector I to promote circulation through the upper boiler part. The pipes Ri and R are large enough to allow natural circulation when the pump is not running and valves (not shown) in lines F and Rr are closed, a pipe-stub St at the top of the boiler leading to an expansion pipe being provided for this condition. In a modification, a by-pass line with a valve runs from the expansion pipe to the return line between the pump and a shut-off valve, on the pump's inlet side, so that the pump maintains a forced circulation through the boiler upper part when the central heating system is not in use.
