Title: Improvements in apparatus for recording and reproducing sound
IPC: G10H3/06
Filed: 1924-10-23
Abstract: 247,629. Fournier d'Albe, E. E. Oct. 23, 1924. Optical apparatus.-Relates to apparatus for optically recording and reproducing sound. According to the invention, a photographic record is made by means of light-reflecting reeds attached to resonators tuned to the same frequencies as the reeds. In this way, the sound to be recorded is analysed into constituent vibrations which are recorded simultaneously, by individual pencils of rays, as broken parallel lines on a photographic film. Reproduction is effected by breaking up light from a steady source into intermittent pencils, the frequencies of which correspond with those of the tuned resonators, and passing these pencils of light through the component photographic records on to a selenium cell which operates a telephone in known manner. Fig. 1 shows diagrammatically a recording apparatus in which five resonators b are employed, each carrying a silvered reed b<1>, and each resonator and associated reed being tuned to respond to a particular note. The sound to be recorded is directed from a trumpet a on to the resonators. Light from a source c is reflected from the reeds b<1> in separate pencils, which pass through perforations in a screen g and act upon a moving sensitized film f. The resonators may be rectangular, or as shown in Fig. 4, may be spherical. In this arrangement, the resonator is adjustably mounted in a holder r. Fig. 2 shows apparatus for reproducing from the record f, which is moved between a selenium cell k and a slotted screen i. Intermittent rays or flashes of light, corresponding in number and individual frequency to the notes to which the recording resonators are tuned, pass through a slot j in the screen, and through the separate sound-traces on the record film f to the cell k. The intermittency of the rays is produced by rotating an opaque disc l across a beam of light from a source n, the disc having the required number of concentric rows of perforations m, suitably spaced. Lenses o, p are arranged as shown. Alternatively, the light breaking-up device mav comprise a cylinder having along its length coaxial circles each divided into different numbers of opaque and transparent portions. The record may be interposed between the light source and the breaking-up device.

Title: Improvements in and relating to machines for capping or sealing packages or containers
IPC: B65B31/02
Filed: 1918-12-23
Abstract: 144,174. Marks, E. C. R., (Anchor Cap & Closure Corporation). Dec. 23, 1918. Capsules and the like, applying.-In apparatus for capping or sealing packages or containers for food or other products in vacuo, a package receiver is movable to position a package beneath the sealing-head, and relative movement is produced between the receiver and head whereby the latter covers the former and hermetically encloses the package, means being provided to exhaust the air from around the enclosed package. The invention is described in connexion with the exhausting and sealing machine described in Specification 134,683. The vacuum chamber 18, Fig. 3, consists of a cylindrical sleeve 51 which co-operates with a foot-plate 52 and a sealing-head' 53 on the bracket 24. The glass container 50 to be sealed is of tapering form and is supported in a holder 54 adapted to reciprocate in the sleeve 51. As shown, two sleeve-holders are slidably mounted in a turret 55 rotated intermittingly by a shaft 56 driven through gearing 60, 61, 63, 64, Fig. 1, from the shaft 15, so that each sleeve is successively brought into registration with the head 53. The plate 52 is carried by a rod 66 reciprocated through a rod 70, crank 69, and arm 68 from a cam 67 on the shaft 15. An ejector 71 to facilitate the insertion and removal of the containers is operated by a lever 72 actuated by the rod 66. The exhausting-means comprises a trunk piston 12 working in a cylinder 11 communicating by ports 16, 17 with the chamber 18. The piston is operated by a rod 13 from a crank 14 on the shaft 15, and a valve 19 controls the ports 16, 17. The sealing-mechanism is preferably identical with that described in the prior Specification, and comprises a pair of annular dies 21, 22, the lower die 21 being adjustably supported in the chamber 18, and the upper die 22 adjustably mounted in a plunger 23 reciprocated by a lever 26 operated from a cam 31 on the shaft 15. The closing of the two dies compresses the beading formed on the rim of the closure, and forces a. gasket laterally from the beading against the wall of the container. The shaft 15 mav be driven either continuously or intermittingly, its operation being controlled by a pedal 33 adapted to operate a clutch, the driven member of which is driven from a belt pulley 45, the arrangement being such that the shaft 15 is rotated one revolution each time the pedal is depressed. In operation, the ejector 71 and foot-plate 52 move upward simultaneously while the turret 55 is at rest, and the plate 52 raises the sleeve 51 into contact with the head 53, hermetic joints being formed by gaskets 75, 76. After the sealing operation, the ejector and foot-plate move downward until they are clear of the sleeves 51 and the turret 'is rotated.

Abstract: 205,500. Kuntz, J. E. Oct. 14, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Cam and lever actuated pumps ; stroke, varying ; regulating delivery. -A device for injecting liquid fuel into the cylinder of internal combustion engines comprises two pumps arranged in series. Fuel is delivered under low pressure by a cam-actuated pump x, Fig. 2, through a cam-actuated piston suction and delivery valve 7 to a chamber 23, which is connected to a fuel injection nozzle and to a chamber 25 in which works a high pressure injection pump plunger 8. On the descent of the plunger 8 injection takes place past the injection valve (not shown) which is lifted off its seating by the pressure of the fuel. The quantity of fuel injected is varied by controlling the stroke of the plunger 8. A yielding plunger 15 working against an elastic buffer ensures that the pump 6 shall only deliver at a lowpressure, and reduces the delivery of the pump to an amount sufficient only to replace in chamber 23 the fuel previously injected by the plunger. 8. A cam 30<2> for imparting a variable stroke to the plunger 8 is shown in Fig. 5. This cam is mounted on an angularly adjustable eccentric 32<2>, and is prevented from rotating with the eccentric relatively to the camshaft 31 by key 30<3> sliding in a radial slot on the camshaft. The eccentric may be rotated by means of the nut 44, connected by a pin 35 working in slots 36 to a rod 34 axially adjustable within the hollow camshaft.

Abstract: 323,037. Standard Telephones & Cables, Ltd., and Blumlein, A. D. Sept. 13, 1928. Phantom systems.- The ratio arms of an alternating - current Wheatstone bridge consist of two inductive windings which are bifilarly wound on the same core and are surrounded by a shield which is connected to the common middle point of the ratio arms. As shown in Fig. 1, the windings 1, 2 and 5, 6 are formed of a twisted pair of conductors and are wound by starting at the ends 2, 6, so that the ends 1, 5 appear at the outside. The windings 3, 4 and 7, 8 are similarly wound but in the reverse winding direction. The coils are connected as shown to terminals 9, 10, 11 and are inserted in a Wheatstone bridge to form the ratio arms. For currents entering at the point 10, the windings oppose inductively, giving a small impedance while for currents passing through the coils from the end 9 to the end 11 the windings aid inductively and present a very high impedance. A coil for 4 to 1 ratio arms is wound from a fourconductor strand; one arm comprising four windings in series and the other comprising two pairs of conductors in parallel. Similarly other ratios mav be obtained. As shown in Fig. 6, the coil windings 9, 10 and 10, 11 form ratio arms bridged across the conductors 38, 39 of a side circuit in a telephone phantom group. The shield 41 of the ratio arms and the shield 42 of the side circuit repeating coil are connected to the mid-point 10 from which a conductor 40 gives access to this half of the phantom circuit.
