Title: Circular disc, calibrated in angles, for the easier taking of panorama photographs
IPC: F16M11/08
Filed: 1957-07-05
Abstract: 811,202. Protractors. GUNYON, M. J. July 5, 1957, No. 21261/57. Drawings to Specification. Class 97(3) A circular disc is marked off with consecutively numbered or lettered radii to facilitate the taking of a series of panoramic photographs by indicating the directions in which the camera should be successively pointed in order to obtain a series of photographs with sufficient, but not excessive, overlap. The disc may have several groups of radial lines, for use with different kinds of cameras, and may also be provided with extensions of the radial lines, or lines parallel to but spaced from the radial lines. In use, the camera is secured by means of its tripod bush to the centre of the disc. The optical axis of the camera is then adjusted to be parallel to each of a group of radial lines consecutively, and exposure being made after each alignment. The angle between the lines of a group is so chosen, for the camera to which it pertains, that the photographs slightly overlap. The disc may be supported on a tripod, or it may be held in the hand, in which case it may be fitted with a small magnetic compass set below the surface of the disc.

Streptomyces caelicus or S. griseus 20129 or their antibiotic 11072 RP-producing mutants on a nutrient medium containing an assimilable source of carbon, an assimilable source of nitrogen and inorganic salts and separating the antibiotic therefrom. Preferably the culture is effected at an initial pH of 6.0-7.8, a temperature of 23-35 DEG C. for 2-5 days.  The antibiotic is separated from the culture filtrate by extraction with a water immiscible organic solvent, e.g. an aliphatic alcohol of 1 to 5 carbon atoms, an aromatic alcohol, a ketone, an ester or a chlorinated aliphatic hydrocarbon, preferably at a pH of 2-6.  The extract is concentrated and precipitated with a non-solvent for the antibiotic, e.g. hexane. The mother liquors are passed through an alumina column and eluted with a solvent for the antibiotic. The antibiotic is purified by chromatography, e.g. in chloroform over alumina or countercurrent distribution.  The antibiotic may be used in therapeutic compositions together with diluents and/or other therapeutically active substances, for example, in the form of tablets in the treatment of tuberculosis.

Title: Improvements in or relating to television and like receivers
IPC: H04N5/68
Filed: 1934-07-27
Abstract: 426,173. Television receivers. TELEFUNKEN GES FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. July 27, 1934, No. 21993. Convention date, July 27, 1933. [Class 40 (iii)] In a television or like receiver incorporating a cathode-ray tube of the type wherein the intensity of the electron beam is controlled by potentials applied to a control electrode substantially symmetrical with respect to the axis of the beam, the picture modulation in the tube is effected by amplified signal modulated high frequency or intermediate frequency energy which is applied directly to said control electrode without previous demodulation. The carrier frequency applied to the tube is at least twice the highest picture point frequency and the amplification of the signal modulated energy is effected by one or more multi-grid valves. When hexodes or heptodes are employed they are connected in an aperiodic back-coupling circuit arrangement giving substantially uniform reduction of damping of the output circuit for the whole television frequency band employed. The Specification as open to inspection under Sect. 91 states that with intermediate frequency amplification the output valve may be arranged as an anode rectifier, the output being applied directly to the cathode-ray tube. This subject-matter does not appear in the Specification as accepted.

In the Fig. 4 embodiment a hydrophone for incorporation in the streamer includes a pair of series-connected piezo-electric elements 44, 46 mounted on a flexible metal diaphragm 40 and parallel-connected with a similar pair of elements 48, 50 on diaphragm 42. Each element is a ceramic disc having gold electrodes. The diaphragms are held by a plastics mount 34 within a stainless steel sleeve 20 sheathed with a shock absorbent rubber or plastics layer 21. The assembly of elements and diaphragms is encapsulated in a polyurethane plastic. The element interconnections and polarization provide a first-order cancellation of acceleration noises in the hydrophone output. A secondorder cancellation of noise is obtained by appropriately orienting and interconnecting several hydrophones of the above type. The spacings of the hydrophones along the streamer are chosen such that selected noise wavelengths are attenuated in the combined output of the streamer.

Title: Improvements in and relating to overhead runway conveyor systems
IPC: B65D88/58

Abstract: 857,557. Grab buckets. PARKER MITCHELL ENGINEERING CO. Ltd., and PARKER, W. J. July 9, 1959 [July 10, 1958], No. 22188/58. Class 78 (4). A bucket 12, Fig. 1, is supported by a cable from a winding drum 4b carried by a bogie 1a which is pulled along a rail H by a second bogie 4. The bucket is moved between loading and unloading stations and can be raised or lowered at these stations by the winding drum 4b. At each loading station a pair of ramps 27 is secured to the rail H with which rollers 16 co-operate. As the bogie approaches a loading station the rollers 16 are forced downwardly by ramps 27 taking with them rollers 17, Fig. 2. Each roller 17 co-operates with an inclined face 18, Fig. 1, of a lever 19 which pivots about a pin 20. Through spring-biased contacts 21 the levers 19 turn the downwardlyextending arms 22 about their pivot so that their slots are moved clear of hooks 24. When the bucket is lowered the said hooks move therewith so that the bottom sections of the bucket remain in the closed position. The bucket can then be loaded, raised and transferred by means of the bogie to any selected discharging station. As the bogie leaves the loading station the roller 16 moves clear of the ramps 27 and the rollers 17 move clear of the inclined faces of the levers 19. This results in the arms 22 being moved so that their slots receive the hooks 24. When the bogie stops at a discharging station the bucket is lowered but as the hooks 24 now engage with the slots thev are not lowered with the bucket. Thus the bucket descends relative to the arms 25, which through the links 25a, Fig. 2, turn the bottom sections 25b about pivots 26 so that the contents of the bucket are discharged.
