Title: Improvements in or relating to the tuning of radio receivers
IPC: H03J5/14
Filed: 1938-10-13
Abstract: 520,335. Electric control systems. COLE. Ltd., E. K., and WYBORN, E. J. Oct. 13, 1938, No. 29619. [Class 40 (i)] In a press-button radio receiver tuning system of the motor controlled commutator type, the contacts co-operating with the commutator are separated into different wave ranges and mounted on separate supporting bars or sets of bars which form part of the circuits of the motorcontrolled wave range switch. This arrangement facilitates the changing over of any particular push-button from control for a station in one range to a station in another range. As shown, the bars 6, 7, 8 carrying contacts 9L, 9M, 9S of long, medium and short wave stations respectively are dissociated from the commutator but in practice they are mounted one behind the other alongside the commutator. When a button is pressed, a station contact and a wave range contact L, M or S are energized and if the range contact is not in the gap of the range control commutator 2, motor winding 3a or 3b is energized and a winding 13a or 13b clutches this commutator to the motor and opens contacts S1, S2 to disable the tuning control circuits. When the selected contact 9L-9S lies in the gap, 13a or 13b is de-energized to de-clutch the range commutator and complete the motor control circuits over the' station commutator 1. Specification 497,774 is referred to.

Abstract: 1431574 Material level monitoring; rotary conveyers XEROX CORP 25 June 1973 [28 June 1972] 29976/73 Headings B8S and B8A The level of particles 50 stored in a container 54 is monitored by a sensing device movable from a first to a second position when the particle level drops to a predetermined level, closing an electric circuit to energize a visual or audio signalling device. The sensing device comprises a rotatably mounted shaft 56 having a planar surface 60 extending radially therefrom to extend down to the predetermined level of particles in the container. Attached to the shaft 56 and spaced therealong from the surface 60, is a bar magnet 64 which is urged by adjacent bar magnets 68, 70 secured inside the container, into alignment therewith to close the said electric circuit. Rotation of the shaft 56 for magnet alignment is prevented by the planar surface 60 reacting against the particles 50, unless the level drops to the predetermined level, whereupon rotation occurs and the signal is generated. A sliding gate 62 at the base of the container 54 dispenses the particles 50 when required for mixing with ferromagnetic carrier granules 26 in the bottom of a housing 10. The mixing of granules and particles generates an electric charge between the two which facilitates conveyance to the drum 46 of an electrostatographic printing machine. The mix 26 is lifted from the housing base by a bucket wheel 12, having alternate buckets apertured so that some mix drops therethrough to the housing base facilitating further mixing, a transport roll associated with magnets 38 attracts the mix from the wheel 12, the amount transferred being controlled by a metering blade 40, and a developer roll 16 with magnet 42 transfers the mix from the roll 14 to the drum 46.

Title: Process for the production of a combined coloured picture and sound record film
IPC: G03C7/24
Filed: 1932-10-26
Abstract: 412,949. Combined sound - record and coloured picture films. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. Oct. 26, 1932, No. 30009. [Class 40 (ii).] Relates to the production of single- or multilayer films bearing a sound-record and coloured pictures. According to the invention, the photographic material employed has dyestuffs or dyestuff-forming substances diffusely incorporated therein, and upon the conversion of the picture portion of the film into a dyestuff image, either the portion of the film bearing the sound record is not changed, or the converted soundrecord portion is reconverted into a black image on a transparent or coloured ground. Prevention of the conversion of the silver sound-record into a dyestuff image may be effected by the local application of a resist such as varnish or a fatty substance ; or a chemically active resist may be used, which acts oppositely to the agent employed for the formation of the dyestuff. As an example of the latter method, if an oxidizing bath is employed for converting the silver picture images into dye-stuff images, the silver sound record may be protected by means of gum arabic and sodium hydrosulphite. When the sound record has been changed into a dye or silver compound image, it may be reconverted into a silver image, with previous, subsequent, or simultaneous destruction of the dyestuff, by means of sodium hydrosulphite alone or with amidol. In the case of a multi-layer film, if dyestuffs are employed which do not interfere with sound-reproduction when ultra-violet or infra-red rays are being used, destruction of the dye in the layers at the part where the sound-track occurs is unnecessary. Specifications 369,616, 379,679, 395,718, 397,159, 397,188, and 397,192, [all in Group XX], are referred to.
