Abstract: 430,491. Electric signalling and distant control systems. HERINK, H. J., 9, Page's Hill, Muswell Hill, and REID, D. G., 56, Forestdale, Southgate, both in London. Dec. 16, 1933, No. 35465. [Class 40 (i)] In signalling or control systems for repeating at a distance the movements of a member, the transmission is effected by a mixture of current of two components each having a fixed frequency, the amplitudes of one or both of the components being varied in accordance with the movement to be signalled. The signals may be transmitted over power, telegraph or telephone lines, over a separate line or by wireless. As shown the master instrument I controls differentially a condenser K the plates of which are connected so as to control the amplitudes of the outputs of two oscillators O<1>, O' of fixed frequencies. The mixed frequency current received at the receiver is separated out by the detector-amplifiers V11, V111 ; V22, V222 and applied to a crossed-coil instrument which is operated in accordance with the relative magnitudes of the two components of the signalling current. Instead of a condenser, an inductance or resistance may be employed. In a modification, the two components are separated and rectified and applied to respective variable-mu valves the outputs of which are modulated by carrier currents of different frequencies. In a further modification one component only is varied. Reference has been directed by the Comptroller to Specification 405,018.

Title: Improvements in or relating to web-feeding apparatus
IPC: G03B1/42
Filed: 1953-12-22
Abstract: 735,849. Kinematograph apparatus. KODAK, Ltd. Dec. 22, 1953 [Dec. 24, 1952], No. 35569/53. Class 97 (1). [Also in Group XVI] A web control arrangement, wherein a frictional drive for feeding the web into a loop in advance of a feeding means adapted to feed the web from the loop, comprises a rotatable drum around which the web is wrapped, and a pivoted roller movable to an operative position at which it effects a frictional feed of the web into the loop without appreciable slippage at a rate faster than it is withdrawn from the loop, and wherein part of a loop-confining means into which the loop extends is movable by the loop when it increases in size to cause movement of the pivoted roller, thus varying the slippage. As shown, a motion picture film F is fed by a drum 13 to a loop L from which it is drawn intermittently by a claw 16 engaging perforations in the film. A V-shaped cam follower 15 is held in contact with a rotary cam 14 by a spring 21 engaging a pivoted arm 19 pivoted to the follower 15, such that rotation of the cam 14 effects upward intermittent feeding of the film. The film is normally pressed against the drum 13 by a presser roller 25, such that the drum 13 feeds the film faster than the claw 16. The roller 25 is rotatably mounted on a shaft 30 fixed to a lever 31 pivoted by a shaft 32, to an arm 33 journalled on a shaft 34 fixed to a plate 12. The shafts 30, 32 are arranged eccentrically, such that a spring 84 attached to the lever 31 swings the roller 25 into engagement with the drum 13. The loop L is confined between a stationary guide 38 and a movable guide 40 fixed to the lever 31, the surfaces of the guides being concave to prevent damage to the film. When the loop L lengthens sufficiently, the guide 40 is rocked against the action of the spring 84 to space the roller 25 away from the drum 13, thus permitting slippage, between the film and drum. As soon as the loop diminishes sufficiently, the guide 40 returns to its former position, thus causing the roller 25 and drum 13 to feed the film without slippage. The drum 13 has narrow film-supporting surfaces 22 and 23, while the roller 25 has a cut-away centre portion in order to prevent abrasion of the image area of the film. A switch 50 is actuated to stop the drum and claw drive should the loop L be shortened by a predetermined amount. In a modified form, Fig. 6, not shown, the film is fed vertically downwards, instead of vertically upwards, from a loop.

Title: Improvements in and relating to methods of and apparatus for photographic sound recording
IPC: G11B7/00
Filed: 1930-11-26
Abstract: 373,974. Optical sound - recording. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kellogg, E. W.; 1185, Ardsley Road, Schenectady, New York, U.S.A.) Nov. 26, 1930, No. 35610. Convention date, Nov. 26, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] In making a variable-width sound record, for example a record of sound received by a microphone 20, Fig. 1, and amplified by a valve amplifier 22 connected to a printing galvanometer 26, the weak sounds are over-amplified and simultaneously and automatically the printing light is dimmed, for example by means of a rheostat 28 in the circuit of the lamp 25 coupled to a volume control 32 on the amplifier, or by means of a " light wedge " in the path of the light. This gives a negative, Fig. 4, in which a weak sound 12 is recorded on the right-hand side of substantially the same amplitude as a strong sound on the left-hand side but having a greyish part 11 instead of the dead black on the left. In the positive, Fig. 5, the corresponding transparent part becomes partially opaque for the weak sounds on the right. When such a record is reproduced, the relative sound intensities are automatically reproduced, but the ground noise is reduced during the soft passages. A positive may be obtained directly by the known process of reversing or by an apparatus as in Fig. 6, in which the transparent part of the film is fogged by a separate lamp 36 controlled by the rheostat 28 or provided with a " light wedge " controlled by the rheostat. The amplifier 22 is provided with an independent volume control 31 in addition to the volume control 32 connected to the light control. If desired, the regulation of the amplitude and amount of light may be performed automatically by means responsive to the volume of the sound. Variable-density records may be similarly produced with automatically varied density ratios.

Title: Preservation of food and other perishable materials
Inventor: WEBSTER THOMAS JOHN
IPC: A23L3/36
Filed: 1956-11-21
Abstract: 812,210. Preserving perishable materials. BRITISH OXYGEN CO. Ltd. Oct. 10, 1957 [Nov. 21, 1956], No. 35655/56. Class 49. [Also in Group XIII] Food and other perishable materials, e.g. corpses, are preserved by cooling with liquid air or nitrogen in a thermally-insulated container to below - 50‹ C., e.g. to about - 190‹ C., the liquid air or nitrogen having been liquefied by using liquid methane as refrigerant. In one form of the invention, air or nitrogen is compressed to 15 or 20 atmospheres, cooled to about - 160‹ C. by heat exchange with cold gaseous methane, liquefied by heat exchange with evaporating liquid methane, passed to a storage tank and thence to a thermally-insulated vessel containing food or other perishable material (preferably pre-chilled to about - 5‹ C.) until the desired low temperature is reached. In the form of the invention shown, risk of forming explosive mixtures of air with methane is avoided by cooling air with methane-cooled cooled nitrogen. Air at about 32 atmospheres leaves a compressor 10, is cooled and purified in heat exchanger 11 by a countercurrent stream of cold nitrogen and also any waste gaseous oxygen deriving from column 16, and is liquefied in heat exchanger 12 by heat exchange with liquid nitrogen evaporating at about 5.7 atmospheres. The liquid air may be fed directly through valve 13 into a thermallyinsulated container 14 containing perishable material, or it may be fed through valve 15 to rectification column 16 in which it is separated into fractions of liquid nitrogen and gaseous oxygen, these fractions being used respectively for cooling purposes in container 14 (after storage in vessel 19 if desired) and to assist in cooling air in heat exchangers 11 and 12. Nitrogen leaving exchanger 11 is compressed and cooled and passed through heat exchanger 22 and heating coil 23 by means of which heat is exchanged with evaporated methane in exchanger 22 and heat is supplied to evaporate liquid methane in storage vessel 24, thereby liquefying the nitrogen which is passed to heat exchanger 12. Nitrogen not required for heat exchanger 11 passes via line 26 to a heat exchanger 28 where it serves to cool nitrogen by-passing heat exchanger 22 through line 29. When liquid air is used for cooling purposes in container 14, enrichment of oxygen occurring in the container due to preferential vaporization of nitrogen during the cooling of the food &c. may require that the container after cooling be flushed out with a small amount of gaseous nitrogen to reduce the oxygen content therein. Specification 804,944, [Group XXVIII], is referred to.

IPC: E01B35/00
Filed: 1967-08-04
Abstract: 1, 199,962. Aligning railway tracks. F. PLASSER. Aug.4, 1967 [Aug. 5, 1966], No. 35964/67. Heading G1F. A method of aligning railway track particularly at curved sections comprises the use of two chards 1, 2 the first of which is disposed with its rearward end 3, viewed in the direction of working, in the already corrected region of track and its forward end 7 projecting into the uncorrected region of track, the end 7 being connected to the other chard 2 located in the uncorrected region of the track and the first chard 1 being used to obtain comparison values to enable the position of the track to be corrected at a point 4, which may or may not coincide with the end 5 of the chard 2. The end 7 of the chard 1 is preferably located near the centre of the chard 2 and this arrangement reduces errors which are due to the necessary portioning of the forward end 7 of the chard 1 in the uncorrected region of track. These errors may be further reduced, if desired, by connecting the end 8 of the chard 2 to the centre of a further chard. An arrangement is also described wherein when using tensioned wires to represent the chards the tension in the wires is taken by separately anchored springs so as not to distort the chard 2 where it is connected to the chard 1.

Abstract: 1,178,535. Rolling; making heat exchangers. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 17 July, 1967 [11 Aug., 1966], No. 36007/66. Headings B3A and B3M. Two or more layers of metal, the outermost layers of which are of the same metal, are bonded together by passing the layers between the rolls 1 and 2 of a pendulum mill, the layers being subjected by the rolls to simultaneous pressure and heat during rolling. In an example, two layers 15 of titanium are bonded to a central layer 16 of aluminium, the layers, after cleaning and assembly, being sealed by a thermoplastic sealing compound 18. The compound softens during the rolling and falls from the assembly. The assembly is fed towards the rolls at 2 feet/min., while the rolls oscillate at a speed of 340 ft./min. The layers need not have their surfaces cleaned to remove oxidation before the rolling step, but in this case the resulting bond is not so strong. In a further example, two layers of aluminium are bonded together after selectively coating the surface of one layer with stop-weld material and sealing the edges of the layers together as before. The finished strip is stored as a coil and subsequently cut into lengths suitable for heat exchanger panels, the lengths finally being expanded by air or hydraulic pressure to produce desired passageways between the layers.
