Title: A station and remaining-time indicator for use in railway and other vehicles
IPC: B61D41/00
Filed: 1930-10-31
Abstract: 360,657. Indicators. NICOHOSOFF, E., 5, Rue Fouad Ier, Alexandria, Egypt. Oct. 31, 1930, No. 32762. [Class 3 (i).] An indicator for use on railway or other vehicles comprises an apertured face-plate at one opening 3 in which is displayed on an endless or non-endless band 9 the next stopping place, and at another opening 5 the number of hours and minutes which remain before that place is reached, or should the train be late, the amount it is late. At the aperture 7 is a legend " remains " or " late " controlled manually by a lever 49. The hours and minutes may be on endless or non-endless bands, on drums, discs, or on feathering paddle-boards &c. The indications at apertures 3 and 5 are set by hand at each stopping place by means of push-in and rotatable knobs 17, 34, and during the progress of the train the hours and minutes are automatically changed by gearing from a clock 51. When during a journey the train becomes late, in addition to actuating the lever 49, a pointer 43 is turned from the position F to the position L, thus reversing the motion of the hours and minutes display carriers, and when the train is stationary or shunting, these carriers are stopped by putting the pointer 43 at S. The indications may be illuminated from the rear. Several indicating devices in different compartments may be connected electrically. The band 9 may be removable for replacement in the case of long journeys. An electric bell may announce automatically the approach of the next stop.
Patent GB-434858-A (GB)
Title: Improvements in the manufacture of artificial staple fibres
IPC: D01F2/30
Filed: 1934-11-14
Abstract: A process for the production of staple fibres or yarn spun therefrom comprises the steps of forming continuous artificial filaments, threads, yarns or like materials from spinning solutions having a basis of organic derivatives of cellulose and containing wax-like compounds which are formed by reaction between higher fatty acids such as stearic palmitic or oleic acid and di- or polyhydric alcohols, alkylolamines or ammonia and which are readily dispersible in aqueous media, converting such continuous artificial filaments, threads, yarns and like materials into staple fibres and crinkling and delustring the materials by treatment with hot aqueous media. The treatment with hot aqueous media must be more vigorous, e.g. at a higher temperature, than for mere delustring.  The wax-like compounds may be used alone or in combination with other substances, e.g. cresylic acid, butyl acetate, polymerized fatty acids, glycero-boric acid, glycoboric acid, cetyl alcohol or esters or ethers of higher fatty alcohols. The compounds may be employed in proportions of 1--20 per cent, but preferably of 3--7 per cent of the cellulose derivative; depending on the compound employed and its solubility in the spinning solution.  The spinning solution may, if necessary, be filtered at a raised temperature.  The spinning solution may also contain ceresin wax, beeswax, stearic acid, palmitic acid, ozokerite wax, carnauba wax, chlorinated naphthalenes, and like substances which are not readily emulsifiable in water or soap solutions.  In an example diethylene glycol stearate is dissolved in heated acetone, and added to a solution of cellulose acetate in p  acetone to form a solution containing 5 per cent of the stearate based on the weight of cellulose acetate.  The solution is dry spun to form filaments which are crinkled by treatment in 0,2 per cent aqueous soap solution at 95 DEG  C. for 30 minutes and then stapled.  In the above example diethylene glycol oleate, glycerol di-stearate or a mixture of equal parts of diethylene glycol stearate and triethanolamine stearate may replace the diethylene glycol stearate.

Filed: 1946-11-07
Abstract: 621,171. Rotary cutters. THURLING, B. Nov. 7, 1946, No. 33088. [Class 31 (i)] [Also in Groups XXII and XXIII] A rotary cutter is made up of two parts, each comprising a bush and a number of cutting blades, the blades of one part being arranged to intermesh with those of the other part, the bushes forming a continuous bore. One set of blades may be of slightly smaller diameter than the other, whereby they take no part in the cutting action but stiffen the cutting blades. Owing to the gaps between the blades on one part, the blades are easier to sharpen than a one-piece cutter with the same total number of blades. Fig. 2 shows one half of a cutter, in which 1 is a bush and 2 the spaced cutting blades which intermesh with similar blades on a complementary half. Figs. 3 and 4 show another form in which the non- cutting blades 9 attached to the bush 8 are interleaved between the blades 6, specially shaped for trimming the edges of boot or shoe soles, carried by the bush 5; in this example, the bushes 5 and 8 of the two parts adjoin one another at the same end of the assembled cutter.

Abstract: 422,650. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Goldstine, H. E. ; Rocky Point, Long Island, New York, U.S.A.) Nov. 27, 1933, No. 33201. Convention date, Jan. 31. [Class 40 (v)] A phase modulated transmitter comprises a valve with three or more electrodes, arranged as an oscillator or having high frequency oscillations applied to the control grid, the operating conditions being such that grid current flows, and modulating. potentials being applied to any of the electrodes so as to vary the flow of grid current. The grid-cathode path of the valve is in effect a capacity shunted by a resistance the variation of which gives rise to phase modulation. The phase displacements are preferably limited to a small angle to avoid amplitude modulation. In the arrangement shown in Fig. 1, valve C is a crystal-controlled oscillator, the grid of which is connected to earth (1) over a variable inductance 22, to compensate for anode-grid capacity, in series with condenser 23 to prevent direct-current flow and (2) over resistance 24 to apply grid bias, a meter 26 being inserted to indicate grid current. The heater is supplied by transformer 21 the secondary of which is connected to ground over condensers C1 to prevent high frequency oscillations reacting on the transformer. Modulating potentials from source A are applied over condenser 34 to reactance B connected between the cathode and earth, condenser C2 serving to byepass high frequency current. In a modification, Fig. 3 (not shown) a transmitter comprising a symmetrically connected pair of valves with long line frequency control and a common tank circuit is phase modulated in similar manner. In other modifications, Figs. 4 and 5 (not shown), the modulating potentials are applied to the grid circuit. Modulating potentials may also be applied to the anode or to a screen grid provided that they have a controlling effect on grid current.
