Abstract: 982, 547. Flowmeters; measuring fluid flow electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 9, 1961 [May 12, 1960], No. 16834/60. Headings G1N and G1R. A fluid flow measuring device comprises a movable, U-shaped section of pipe 12 whereby the direction of flow of the fluid is altered, the force exerted thereby on the pipe section 12 being measured as an indication of rate of flow. The section 12 is maintained in position by an electrical servomechanism the power to operate which is indicated on an electrical measuring instrument as a measure of flow. The section 12 is connected to inlet 10 and outlet 11 pipes by bellows 13 or like coupling of high compliance and, to balance static pressure, is enclosed in a chamber 15 filled with fluid bled from the pipe through a hole 16. A projection 17 operates an electrical transducer 18 when the section 12 moves. The output from the transducer 18 is fed through a servo-amplifier 21 to operate an electro-mechanical transducer 23 which restores the section 12 to its original position by way of a coupling 25. Inlet 10 and outlet 11 are interconnected by a by-pass 26 in which a piston 27 is vibrated by alternating current of fixed frequency f and constant amplitude from an oscillation generator 30. Output from the amplifier 31 passes to a filter 32 which separates the first harmonic frequency # from the second harmonic 2f and feeds the resulting signals to indicators 34, 35 and 36 to indicate volume flow, mass flow (#f) and density (#2f) respectively. Honeycomb structures (not shown) in the pipe ensure a cross-sectional velocity distribution independent of velocity of the fluid mass.

Title: Sulphamic acid derivatives
Inventor: CARDY CHARLES FREDERICK
IPC: B01J12/00
Filed: 1964-04-24
Abstract: N-substituted sulphamates are produced by reacting sulphur trioxide in the vapour phase with a monoalkylamine or monocycloalkylamine in the vapour phase.  Suitable amines are, for example, cyclohexylamine, isopropylamine, isobutylamine and isoamylamine.  The process is preferably carried out at a temperature in the range 160-200 DEG  C. and may be carried out in the presence of an inert gaseous diluent. Preferably the amine: sulphur trioxide molar ratio is about 2:1 so that the corresponding quaternary ammonium N-substituted sulphamate is formed. The amine salt may be converted by the usual methods into the acid or a metal salt, for example, the sodium or calcium salt. Examples are given of the preparation of (a) cyclohexylammonium N-cyclohexyl sulphamate with some N,N1-dicyclohexyl sulphamide and cyclohexylammonium sulphate; and (b) isoamylammonium N-isoamyl sulphamate with some N,N1-di-isoamyl sulphamide and isoamylammonium sulphate.

Title: Improvements in or relating to coin controlled vending machines
IPC: G07F17/34
Filed: 1926-07-08
Abstract: 277,145. Lennards, W., and Rolph, W. W. July 8, 1926. Games of skill.- Relates to coincontrolled vending machines nf the kind having in combination with the vending mechanism a number of legend-displaying wheels which are set in motion by actuating the machine and which when they come to rest display various combinations of legends. According to the invention, in order that the wheels may be arrested by the skill of the operator independently of the automatic stop mechanism, the usual detent lever g, Fig. 1, that is normally released automatically by a timing mechanism h acting through an horizontal release lever i, is formed in two portions pivoted together at j and normally held in alignment by a spring k. The upper portion of the detent has a pin n which engages a star wheel e on the axis of the legenddisplaying wheel c to bring this wheel to rest. There are in the machine three wheels and corresponding detents. To stop a particular wheel, the operator depresses one end o of a double-ended lever so that a ramp p on the other end engages the pin n and moves the upper portion of the detent g about its pivot into engagement with the star-wheel e. To prevent the keys o from being depressed before the mechanism has been set in operation after the insertion of a coin, the main operating handle is connected by a chain s, Fig. 3, to a sliding plate v having apertures through which the keys o pass. Each aperture has an oblique lower edge v<1> which locks a key except when the main handle is in its released position. Secondary detent levers x released by the timing mechanism h before the main detents g, stop the wheels c automatically, but these engage the star wheels e in such a position that no successful combination of legends can be obtained, thereby ensuring that a voluntarily controllable machine cannot be used as a purely automatic one.
