Title: Means for producing apparent movement in figures in still slide screen projections
IPC: G02B27/06
Filed: 1935-04-27
Abstract: 452,939. Kinematograph apparatus. FEGAN, D. M., National Bank Chambers, Queen Street, Brisbano, Australia. April 27, 1935, No. 12615. Convention date, July 9, 1934. [Class 97 (i)] Apparatus for producing motion effects by the movement of a line screen over a composite picture, and for projection on to a screen, comprises a carrier unit having a motor and reduction gear thereon, a screen in a frame slidable in the unit by the motor &c. and a composite picture, in the form of a lantern slide, mounted in a carrier; the lines of the screen and slide may be vertical or otherwise, and the screen lines may be wider than the slide lines so that the slide may carry three pictures. Fig. 2 shows a carrier unit with the cover plate, Fig. 3, and end bar, Fig. 4, removed. The unit carries at its lefthand end a motor, connected by a belt to a reduction gear in a casing, to rotate a pinion 31, and an adjustable Bowden wire which passes through a hole 33 in the bottom bar 26 to permit alteration of the inclination of the screen frame. The screen frame, Fig. 7, engages springs 29, 30, carries springs 49, has a rack 32 to engage the pinion 31, and has a lug 50 to facilitate its removal from the carrier unit. The slide carrier, Fig. 5, has a removable push rod 41 to pass through a hole 40 in the end bar, and is inserted between bars. 25, 26 ; springs 34, 35 on the cover plate hold the slide carrier in position, and gaps 36 in the cover plate facilitate the handling of the slides. The screen 21 comprises opaque lines on glass, celluloid, &c., or a slotted opaque substance. The Specification, as open to inspection under Sect. 91 comprises a modification in which the screen is a disc with radial lines rotating over a similarly divided picture. This subject-matter does not appear in the Specification as accepted.

Title: Installation for the continuous casting of a molten metal
IPC: B22D11/20
Filed: 1958-04-22
Abstract: 840,498. Indicating liquid levels. BRITISH IRON & STEEL RESEARCH ASSOCIATION. (Centre National de Recherches Metallurgiques). April 22, 1958, No. 12723/58. Class 123(1) [Also in Group XXII] In a continuous casting apparatus, the mould has at least one capillary conduit terminating at the interior of the mould at a chosen level therein and connected to a source of gas under pressure via a duct fitted with a switch-operating pressure sensitive device which is actuated when the capillary conduit or conduits are obstructed by molten metal. The capillary conduit 6, Fig. 1, is fed with pressure gas from a reservoir 7 through a duct 8 which contains a pressure responsive device 9. Closing of the capillary due to molten metal rising in the mould causes the device 9 to close a switch 20, thereby actuating a warning device 19 and simultaneously a valve 24 which causes pressure gas from the reservoir to operate a piston 37 to close the molten metal outlet 13 and stop pouring. In a modification, Fig. 4, there is a capillary conduit on opposite walls of the mould adjacent the outlet end, and the system gives warning and stops withdrawal by stopping the withdrawal motor 49, when the capillaries are closed due to the molten metal level reaching a dangerously low level. A manual switch 61, when open, renders the system inoperative during the starting period when the capillaries will be closed by the starting bar 60. A device 62 such as a pyrometer also stops the withdrawal if the surface temperature of the withdrawn ingot reaches that at which there is a risk of the solidified skin melting. In a further modification both the systems described above are incorporated in one installation and the electrical circuits are interconnected so that pouring stops if the withdrawal is halted, and withdrawal stops if the pouring is halted. In a further modification, the piston 37, instead of actuating the stopper 12 is connected to a pivoted pouring receptacle.

Abstract: 455,716. Cooling systems; cooling liquids. PAVESI, G., and REVELLI, G., 75<bis>, Via Roma, Mantova, Italy. April 29, 1935, No. 12733. [Class 29] A water cooling system for machine and like quick-firing guns comprises a portable casing 1 having upper and lower water tanks 2, 9, vertical tubes 7 connecting the tanks, a water-circulating pump 10, and an air fan 11. The pump and fan are driven mechanically or by a handle 13, the speed of the fan being greater than that of the pump. In operation, the water from the tank 9 passes through the pump, through a hose 16, around the gun barrel 6, back to the upper tank 2 through a hose 5, and thence through the tubes 7 to the lower tank. The cooling air current created by the fan is discharged through openings 17 in the casing 1.

Abstract: 1,187,722. Pulse radar; aerials. BOEING CO. 18 March, 1968, No. 13018/68. Headings H4A and H4D. An aircraft pulse radar utilizes an aerial system 11, 12, Fig. 2, switched between the transmitter and receiver, a type A display 27, and the carrier frequency is between 1 Mc/s. and 300 Mc/s.; a display is afforded by which clear air turbulence can be recognized, Figs. 4a, 4b (neither shown). Aerials, Figs. 2, 5a, 5b, 5c.- The aerial system comprises a large number of conical parasitic elements 11, Fig. 2, colinear with a primary element 13 and a reflector 14, elements 13 and 14 being housed in a radome. The shape and dimensions of the reflector are illustrated, Fig. 6 (not shown). Element 13, Figs. 5a, 5b, 5c, consists of a plate 37 bolted to the fuselage, pipes 33, 34 connected by a metallic cap 30, a corona ring 29 soldered to pipe 33, a dielectric 38, a pipe 31, a waveguide connected to the duplexer, and a plug 36 integral with a probe 48. Dielectric 38 extends across the seals a notch 32 formed between ring 29 and plate 37. The notch aerial is tuned by moving cap 30 downwardly. An array for affording an end-fire beam off the nose of the aircraft or a broadside effect consists of an array of axially-spaced dielectric-sealed cavity-backed slots down the fuselage. Radar.-In order to add to the protection of the highly-sensitive receiver by the duplexer 21 a gate 25 is added; it comprises a group of diodes from a coaxial cable centre conductor to earth in a conventional arrangement. Ground echo cancellation may be added in known manner. It may be advantageous for detecting clear air turbulence to provide two aerial arrays, which may be of the broadside type. The radar may be time-shared between aerial systems

Breaking and scutching apparatus; grip-chain and like arrangements for feeding, holding, and conveying fibrous materials.-In a machine for depulping the leaves of plants, such as those of Yucca, Dracaena, or like type, in which the depulping is done by stripping-drums working in conjunction with counterbeams, and in which the leaves are carried through the machine by flexible conveyers, being partially drawn through between the stripping-drums, the stripping- drums 1, 2, Fig. 2, are mounted on a common shaft one one side of the conveyer device, which comprises two pulleys 5, 6, an upper rope 7, and two lower ropes 8, 9. Suitable guide pulleys 11 - - 15 are provided. The pulleys are all carried on the free ends of shafts carried by a frame 16 which can be adjusted transversely on the base plate 17, so that the conveyer parts are readily accessible. The bearings 18, 19 of the drum shaft 4 may also be adjustable. The leaves are laid on the lower ropes at a and are gripped by the upper rope 7 and passed round the pulley 5, being operated on by the drum 1 and its counterbeam. An upper rope 10 also passes round the pulley 5. At the point b the ropes leave the pulley 5 and pass round the top of a pulley 12. At the point c, Figs. 4 and 9, the rope 10 separates from the other ropes and passes round a pulley 13.

Wire or the like is packaged in a cylindrical container having concentric cylindrical partitions 4, by coiling it into one compartment until it is filled and then transferring the feed to the next. In one embodiment the wire 7 is fed by a capstan 6 to a flyer 10 the latter being carried on a head 9 rotated by belt and pulley means. The angle of the flyer to the vertical and thus the radius of feed is controlled by lever means 22-24, operation of the lever 24 also varying the speed of the flyer via the gear box 25. In another embodiment, Fig. 3 (not shown), the container is rotated and the wire fed through a pivoted guide the angle to the vertical of which is variable by solenoids. The solenoids are responsive to a counting device which operates when a desired length of wire has been fed into one compartment, to cause transfer of feed to another. The speed of rotation of the container is correspondingly varied. As a further alternative, probes may be used to detect when a compartment is full.
