Title: Method for the checking and the evaluation of the position of  railway tracks
IPC: B61K9/08
Filed: 1971-04-08
Abstract: 1351389 Indicating track condition GERMANY MINISTRY OF TRANSPORT 8 April 1971 9139/71 Heading B7N [Also in Division G1] Apparatus for determining the variations in height of the rails of a railway track comprises two vertical accelerometers 1 (Fig. 1) mounted at opposite ends of a wheel axle 3 of a track testing vehicle, whose outputs are fed through high pass filters and integrated twice. The sum of the displacement signals so obtained is indicative of the average height along the track, and the difference between these signals is a measure of the transverse height variation. The high pass filters may be automatically controlled in accordance with the speed of the testing vehicle. For determining linear dimensional changes in the horizontal plane two accelerometers are mounted on rail feeler members and processed as above to obtain the average track curvature and the transverse track width deviation. The four signals are also combined vectorially with suitable weighting to obtain a figure representing the track characteristic.

Filed: 1934-03-26
Abstract: 432,593. Lifts. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMART, N. C., c/o General Electric Co., Stoke, Coventry. March 26, 1934, No. 9376. Drawings to Specification. [Class 78 (ii)] Electric plant.-In a lift system of the kind in which by the actuation of a single push-button at a floor, the controlling mechanism is so affected that the lift is brought to the caller and thereafter caused to travel to the required floor, calls are registered on a group of electromagnetic storage devices, such as relays, which are k n in number, where n is the number of floors served by the lift, and k is a constant. Each floor has three relays corresponding with the three classes of calls, viz., "effective," "store up," and " store down," and the actuation of a button operates one relay in each of two floor groups, these relays being determined not only by the position of the lift relatively to the caller, but also by the direction in which the lift is, or was previously, travelling, and by the direction in which the caller wishes to travel. The " effective " relay is operated when the lift is travelling towards the caller, and in the direction that he requires to travel. The " store down " relay is operated when the lift is travelling away from the caller, and the required direction of travel is downwards, and the " store up " relay is operated when the direction is upwards. The lift travels in one direction until all " effective " calls are answered, and then reverses and answers " stored " calls for the opposite direction. When the lift stops at any floor, it remains at this floor for a predetermined time even though the doors are not opened. At the end of this time, if the lift is not called, it may, after a further delay, travel to a predetermined parking position. If the lift remains out of use for a further period, the power supply may be cut - off automatically. Specifications 354,847, [Group XXXVII], and 431,594 are referred to.
Patent GB-708481-A (GB)
Title: Improvements in or relating to the preparation of a product containing an alkali metal acid cyanamide
IPC: C08F2/38
Filed: 1952-04-15
Abstract: A product containing an alkali metal acid cyanamide is prepared by heating a reaction mixture of calcium cyanamide, water and alkali metal hydroxide, wherein the respective mol. ratios are 1 : at least 1.5 : at least 0.8, at 60-80 DEG C., preferably 65-75 DEG C., at a pressure not exceeding 9 inches of mercury to remove water from the resulting aqueous slurry of alkali metal acid cyanamide.  The actual reactants may be lime nitrogen, water, and caustic soda.  A wetting agent should be included in the reaction mixture, e.g. Turkey red oil, the product obtained by reacting long chain olefins with nitrosyl chloride and forming an adduct with sodium sulphite, or alkylated aryl sulphonates.  In a modification, the process may be effected in two stages by reacting the starting materials at not exceeding 80 DEG C., e.g. 40 DEG C., at atmospheric pressure, and the resultant slurry is subjected to the vacuum drying at 60-80 DEG C. under the subatmospheric pressure, or the slurry may be filtered and washed and the resulting solution of the acid cyanamide subjected to the vacuum drying.  The material may be treated in more than one vacuum drying stage.  The mol. ratio of calcium cyanamide to water should be 1 : 1.5-5, when effecting the method in a single stage or in two stages without filtration, and 1 : 10-15 when effecting the process in two stages with filtration.

Title: Improvements in speed governors
IPC: G05D13/10
Filed: 1952-04-15
Abstract: 707,121. Fluid-pressure servomotor-control systems. FEILDEN, G. B. R., and RUSTON & HORNSBY, Ltd. April 15, 1952, No. 9411/52. Class 135 In an engine speed governor of the type wherein a flyweight system loaded by a speeder-spring actuates -a pilot valve of a hydraulic relay coupled to the power regulator of the engine, means to give a temporary droop characteristic is included, such means comprising a mechanical linkage between the power device of the relay, the pilot valve, and a pneumatic buffer such that displacement of the power device of the relay in the sense to reduce the power output of the engine causes the extension of the buffer to vary in the sense to augment the total speeder-spring effort, and the buffer is provided with an adjustable leak for regulating the rate at which the speeder-spring augmenting or diminishing effort exerted by the buffer decays to zero. In an embodiment, flyweights 18 driven from the engine through a shaft 12 actuate a single-landed piston valve 28 to control the admission of pressure liquid from an inlet 17 to, or the exhaust of liquid from, a power device 31. The latter comprises a spring-loaded, single acting piston coupled by levers 35, 37 to the power regulator of the engine. The speeder-spring 23 bears on the pilot valve through ball races 24, 27 and the abutment at the other end consists of a thimble 38 rotatable on a lead screw 40 extending from a member 41 which is slidable but non-rotatable in the bore housing the thimble. The latter carries a worm wheel engaging a worm 51 which can be rotated from outside the casing to adjust the speeder-spring to set the speed. The device giving a temporary speed droop includes a lever 53 pivoted on the cap member of the ball race 27 and formed at its lower end with a' knife-edge which is spring-pressed into engagement with the piston 31. At its upper end, the lever is connected by a somewhat flexible rod 61 with the movable end of a bellows 63, the latter constituting the movable wall of a pneumatic buffer chamber 66. Air can leak into or out of chamber 66 past a restrictor 69 formed with flutes at its lower end, and the cross-sectional area provided by the restrictor can be varied by screwing it in or out. The spring rate attributable to the buffer chamber can be varied by altering the volume of the chamber i.e. by partially filling it with oil. A permanent droop characteristic is given to the governor by coupling the piston 31 to the member 41 through the medium of a lever 43 fulcrumed at 45. This fulcrum is carried on a screw 46 so that its position can be adjusted along the lever to give either a positive or negative characteristic. The elasticity of the bellows gives a permanent drooping characteristic which, however, is usually of small magnitude compared with the temporary droop due to the air in chamber 66. Reference has been directed by the Comptroller to Specification 673,989.
