Title: Improvements in or relating to the recording of alternating current impulses
IPC: G01D15/14
Filed: 1940-10-24
Abstract: 545,465. Recording; alternating currents representing sound and the like on coloured films. RADIO CORPORATION OF AMERICA. Oct. 24, 1940, No. 15645. Convention date, Nov. 8, 1939. [Class 40 (ii)] [Also in Group XX] Alternating current representing audio frequencies and the like are recorded so as to produce two differently coloured areas separated by a common boundary line which varies transversely of the record in accordance with the alternating current. In one arrangement Fig. 1, light from a lamp 10 passes through lenses 12 and a two-colour filter 11, to mirror 14 of oscillograph 15 and thence through slit 17 and lenses 18, 19 to film 20. At the same time light from another lamp 21 passes to the film through a slit 22 controlled by a noisereduction shutter 25. This arrangement produces the push-pull record shown in Fig. 3. In a modification, noise-reduction is obtained by blackening the unwanted sides of the track by means of a noise-reduction shutter 33, Fig. 6, having a V-shaped notch so as to cover the unwanted ends of the slit 17. In still an ther arrangement, the two-colour filter has a V- shaped boundary line between the two colours, and the noise-reduction shutter is duplicated, so that two tracks of the kind shown in Fig. 3 are produced side by side in opposite phase. The film currently sold under the Registered Trade Mark "Kodachrome" may be used and may be processed in various suitable ways ; the sound may be re-recorded in various ways. The present records are in some respects similar to those described in U.S.A. Specification 2,102,695 which have not a common boundary line between the two colours.

IPC: H02M7/54
Filed: 1925-06-17
Abstract: 257,695. Deodato, E. June 17, 1925. Commutator switching arrangements.-Apparatus for converting alternating current into continuous or conversely at the same voltage, or for converting current into current at higher or lower voltage, with or without change in its character, consists of two or more sets of storage devices, either electrolytic condensers, ordinary condensers, or accumulators, the units of each set being arranged in series and the sets themselves in parallel and arrangements of brushes moving over the terminals of the units as explained below. Fig. 1 shows apparatus for converting alternating current into continuous or conversely without change of voltage. The two sets of storage units 1 - - 16 and 1<1> - - 16<1> are connected in parallel to two terminals M, N and the terminals of the separate units are connected to the bars of a commutator device over which move brushes C, D carried on opposite ends of a rotating arm E and connected through slip rings a, b to the other terminals A, B of the apparatus. More than one pair of sets of storage units may be employed, a pair of brushes and a rotating arm being provided for each pair of sets. The form shown in Fig. 3 is for converting currents into currents at higher or lower voltages. The arrangement of storage units and commutator is the same as in the previous form, but the brushes R, S are so arranged as to bridge the terminals of one storage unit only. The slip rings a, b are electrically divided, with the result that continuous current is changed into continuous. By the use of individual slip rings continuous current can be converted into alternating or conversely.

Compressed-air engines. - In compressed-air motors wherein a rapid movement is made to the right by passing compressed air to the end g of the cylinder, and a slower movement to the left. by putting the two ends g, h of the cylinder into communication, the return pressure normally acting upon the differential areas of the two sides of the piston, due to the piston-rod, the speed of return at a determined part of the stroke is augmented by putting the end g to atmosphere by means of a fluid-actuated valve f controlled by a needle valve r. Fluid is supplied to end g by a differential, fluid-actuated valve d, the controlling chamber t of which is alternately put to compressed-air and atmosphere by a grooved piston a and ports and passages v, b, t. The chamber ends of valve f communicate with the cylinder end h and passage b by passages s, e respectively. The outlet from chamber p is controlled by the needle valve r. The two ends of the cylinder communicate by passages k, m, l. When the pressure in chamber p falls, the connection b, e being closed by a piston a, the valve f is forced down and thereby the end g is put to atmosphere by ports x.

Filed: 1916-11-10
Abstract: 107,910. Parker, S. Nov. 10. 1916. Healds.-In the manufacture of varnished healds, an extra lease-rod having a cord extending from end to end thereof is employed in the knitting-machine adjacent to one or both of the ordinary lease - rods, and, after the healds have been knitted, the cord is detached from its rod and left in the healds, so that, when the healds have been varnished or sized and dried, the cord may be drawn together between the healds from side to side to loosen or separate them. In plain healds in which both strands of alternate top loops are on opposite sides of the top stave a, as shown, and the bottom loops are divided by the bottom stave b, one extra rod with a cord is employed on either side of the knitting-machine leasing the healds oppositely to the stave a, and, after the healds have been knitted and sized, the rod is removed and the cord c is drawn from one side of the healds to the other: after the healds have been varnished and dried, the cord is drawn back again, so that the healds are crossed and reversed in position, and those which have stuck together are separated without using the ordinary combs and brushes. With fancy healds having both loops traversed by the staves, an extra lease-rod with a cord is employed at each side of the knitting-machine forming a double lease in the healds, and, when the healds have been dried, the positions of the cords are reversed to separate the healds.
