Title: Improvements connected with super tension cables
IPC: H01B9/02
Filed: 1945-07-07
Abstract: 597,957. Cables. BEXON, W. C. July 7, 1945, No. 17388. [Class 36] The stranded conductor a has insulation b covered by a conductive screen comprising spiral turns of copper &c. foil c partially backed by insulation d so as to provide continuity to the screen, an outer layer of polythene being applied over the backing d and having a coefficient of expansion equal to or less than that of the insulation b. Voids and consequent ionisation are thus prevented. The conductor a and screen c are bonded together to avoid electric stress on the layer b. The insulation b may consist of nylon or of a polythene having a higher coefficient of expansion than the outer layer. A final metal or conductive tape may be applied to ensure adequate earthing and with multi-core cables an encircling earthing tape may also be applied.

Title: Improvements relating to indicating apparatus for use on vehicles
IPC: G01P1/12
Filed: 1938-06-11
Abstract: 499,278. Speed and distance recording apparatus. KIENZLE, H. June 11, 1938, No. 17432. Convention date, Oct. 11, 1937. [Class 106 (iii)] In indicating apparatus for use on vehicles having means for recording data such as speed and distance on a chart 10, a mileage recorder is provided with numeral wheels 13 with raised type which project through a slot in a partition 7 in the apparatus, and the chart 10 is provided with a surface which retains impressions after being pressed so that the mileage can be recorded by pressing the pressure sensitive surface of the chart against the type. The impressions of the mileage at the beginning and end of a journey are best disposed one above the other. Setting marks 16 and 17 or pins 18a and 18b may be used to facilitate the positioning of the chart for these readings. A pad 21 mounted on a spring actuated arm 22 may be used to press the chart on type wheels 13.

Abstract: 1,085,412. Epicyclic gear. PANDJIRIS WELDMENT CO. April 21, 1966, No. 17451/66. Heading F2D. A variable-speed transmission comprises a bevel epicyclic gear 10, the speed of the output shaft 15 connected to a crown wheel 20 being controlled by a variable speed shaft 31 driving the planet spider 36 and a shaft 22 connected to the other crown wheel 27 and driven at constant speed. Shafts 22, 31 are respectively driven by pulleys 25, 34 from a motor 55 through a constant speed belt drive consisting of belts 61, 62 and an idler pulley 60, and a variable speed drive consisting of an expanding pulley 55 connected to pulley 34 by belt 63. The motor 55 is mounted on a carrier 50 pivotable about the axis of idler pulley 60 by a manually rotatable screwed shaft 82, this arrangement ensuring that movement of the motor to vary the ratio of the expanding pulley drive 63 has no effect on the belt drive 61, 62. Instead of manual adjustment of the screw shaft 82, this may be effected automatically by a tachometer generator (86) and differential amplifier (92) controlling a motor (93) driving the shaft, Fig. 5 (not shown).

Abstract: 165,734. American Coke & Chemical Co., (Assignees of Roberts, A.). July 11, 1919, [Convention date]. Coke ovens. - In a coke oven in which a netwcrk of interconnected passages is formed in the heating-wall, partitions are provided to divide each wall into a number of independently controllable zones. Each oven is associated with its own heating-walls 20, 21, to which combustible gas and air are supplied at the top, the products of combustion passing downwards through a network of interconnected passages formed by notched blocks constituting the wall. The gas burners 25 open into small combustion chambers 34, to which air is admitted through ports 33 from chambers 32 having inspection openings 31 leading to the top of the oven. Through these openings 31 damper blocks 35 controlling the pcrts 33 can be manipulated. The oven tapers in width from one end to the other, and the burner ccntrolling devices are so adjusted that the coking-time is equalized in all portions of the oven. To ensure that the temperature in the different parts of the wall will correspond with the burner adjustment, vertical partitions or baffles 27, 28 are provided dividing the wall into a number of zones. Products of combustion from the two heating-walls of one oven are exhausted into a sole flue 40, from which they pass through dampered openings 63 into half sole flues 43, 44 communicating with recuperator chambers beneath the oven. From the recuperators lead vertical flues 36 in communication at their upper ends with the chambers 32. The flues 36 for each heating-wall are connected by longitudinal airequalizing passages 38, 39.

Title: Method of and apparatus for measuring times, angles, lengths and for the determination of the direction of sound and the like mechanical impulses
IPC: G01S1/72
Filed: 1922-07-03
Abstract: 184,158. Signal Ges. Aug. 1, 1921, [Convention date]. Locating sounds; determining bearings and distances acoustically.-In apparatus for finding the direction of a source of repeating sound impulses, and for measuring lengths or the angles between the directions of two repeating sounds, or the time interval between the reception of a sound at each of two spaced receivers, the two receivers, which are respectively connected with the two ears of the observer, are placed a long distance apart, and a device for the relative shifting of the sound impressions between the receivers and the ears of the observer has a large range of regulation for a small movement of the adjusting-member. Adjustment is effected until the observer's impression of direction changes more or less abruptly from right to left, or vice versa, the change occurring when the sound reaches the observer's ears at approximately the same instant. The sound impulses may be used to produce records on a moving member, which are then reproduced by devices which can be relatively adjusted to give the above effect. Fig. 3 shows two receivers on a ship, (indicated by dotted outline) connected with needle recording devices n1, n2 producing impressions on a phonograph or like cylinder. Needles n3, n4 reproduce the respective impressions, the sounds being heard in corresponding ear-pieces. The needles n3, n4 can be angularly adjusted relatively to one another. A device is also described in which electromagnetic records are produced on two steel bands arranged around a cylinder. To enable finer adjustment to be made by the central sound-impression method, motor-driven cylinder, &c. may be run at a slower speed. For measuring the length of, for example, a steel rail, the microphone receivers are located' at the points on the rail between which the distance is to be measured, and a sound is sent along the rail by striking it. The time interval between the arrival of the sound at the respective receivers is read on the adjustment scale, and the length calculated by using the known velocity of sound in the metal. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement without sound recording devices, for use on a ship, in which the sound receivers are air chambers connected with the ears by tubes with telescopic or trombone adjustment of the lengths of the tubes. This subject-matter does not appear in the Specification as accepted.
