Title: An improved surveying instrument
IPC: G01C17/12
Filed: 1919-02-28
Abstract: 141,466. Cazalet, M. Feb. 28, 1919. Protractors.-An instrument particularly intended for use in setting out railway cuttings &c. comprises a graduated vertical pillar a, to which is pivoted at f a telescope e carrying a graduated extension rod h. The pillar a also carries a level j and a scale j, on which can be read the positions of indices h formed on the telescope body; mirrors l facilitate observation of the level. Slidably mounted on the pillar a is a block c, on which is mounted a member o capable of sliding horizontally. Hinged at p to the member o is a batter rod q which can be clamped by a screw s to any required angle, measured on the quadrant r. The member o also has a graduated extension t. For setting out cuttings &c. on paper, a similar instrument, without the telescope and level, may be used.

Title: Gas analysis
IPC: G01N31/00
Filed: 1964-02-07
Abstract: 1,000,625. Gas analysis. BECKMAN INSTRUMENTS Inc., Feb. 7, 1964 [Feb. 13,1963], No. 5195/64. Headings G1B and G1N. In an apparatus for the determination of the amount of carbon monoxide in a gas sample stream. Iodine vapour is produced in a converter 21 by the reaction of the carbon monoxide with iodine pentoxide and is delivered to a first electrode (cathode) 38 in an electrochemical cell having a halide solution as the electrolyte, and a second electrode (anode) 44 remote from the path of the iodine vapour, the electrodes effecting the reduction of the iodine vapour and the generation of a current that is indicative of the rate of entry of iodine vapour and thus proportional to the rate of supply of carbon monoxide in the sample gas stream. The converter comprises a cylindrical heater 34 around a central tube 32 containing granulated iodine pentoxide or a mixture of powdered iodine pentoxide with small glass spheres supported on a wad 35 of glass wool. The electrolyte is circulated around the conduit loop 11, 16,10 by bubble lift during which the iodine is dissolved in the electrolyte, the gas passing to atmosphere via a flowmeter 28 and aspirator 30. The electrolyte descends over the platinum cathode and the dissolved iodine is reduced. The electrochemical reactions are given. A conduit extension 12 from the bottom of the conduit loop is passed through a hole in a stopper 15 and communicates with an anode chamber 14 wherein a platinum wire 42 woven through a graphite cloth 44 is immersed in a sludge 46 of active carbon particles to form the anode. A small platinum screen 45 is provided in the vicinity of the point of emergence of the wire from the carbon in order to facilitate the escape of hydrogen during recharging. In a modification, Fig. 2, the cell comprises two separate compartments 52, 76 connected by a plastic sleeve 78 and the sample gas is injected into an inner or cathode compartment 54 of porous glass, porous ceramic or other porous material lined with a platinum cathode screen 56, the compartment 54 dipping into the electrolyte 94 which may be the same as in Fig. 1.

Abstract: 1,205,701. 4-4<SP>1</SP> - Dibromobenzylic acid esters. AGRIPAT S.A. 1 Feb., 1968 [2 Feb., 1967], No. 5212/68. Addition to 1,178,850. Heading C2C. [Also in Division A5] The invention relates to 4-4<SP>1</SP>-dibromobenzylic acid esters of the general formula in which R represents the methyl, ethyl, npropyl or a butyl radical, a halogeno alkyl radical of from 2 to 4 carbon atoms, an unsubstituted or halogenated alkenyl radical of from 2 to 5 carbon atoms or an unsubstituted or halogenated alkinyl radical of from 3 to 5 carbon atoms. Compounds claimed per se are the methyl and ethyl esters. The compounds may be prepared by reacting a compound of the general formula with a compound of a general formula RY in which X and Y are radicals which, with the exception of an oxygen atom, contained in one of these symbols are split off during the reaction. The acid may be reacted with a reactive ester, preferably with a halide of an aliphatic alcohol ROH. In an example, to 4,41-dibromobenzylic acid dissolved in dimethyl formamide are added potassium hydroxide and methyl iodide and the methyl ester subsequently extracted. This can also be obtained by reacting an aqueous solution of a potassium salt of the acid with dimethyl sulphate.

Title: Process for growing a single crystal of quartz
IPC: C30B7/00
Filed: 1950-03-06
Abstract: <PICT:0682203/III/1> Quartz crystals are grown from seed in an aqueous medium containing an alkali metal carbonate or bicarbonate, at high temperatures and pressures, by utilizing the variation of solubility of quartz in the medium with temperatures.  Prepared temperatures are above the critical temperature (375 DEG C) of the aqueous medium but below the inversion temperature of quartz, the temperature difference between quartz seed and nutrient being 1-2 DEG C and the pressure being of the order of hundreds of atmospheres. The preferred solution is 1-2N sodium carbonate, but sodium bicarbonate, potassium, lithium, caesium and rubidium carbonates and bicarbonates are also referred to.  The free space of the pressure vessel after allowing for all solid contents should be filled at least one-third and preferably over one-half full with the carbonate solution to develop the desired pressure. Comparatively large size quartz fragments are preferably used as nutrient to prevent migration of the nutrient to the crystallizing region of the pressure vessel. Suitable apparatus comprises a pressure cylinder 11 surrounded by insulation 29 and resting on an electrical hot-plate 21.  The cylinder is sealed by a plug 16 a shouldder 17 on the plug being forced against a gasket 14 by an annular threaded member 18. External and internal thermocouples 39, 43 and 46 are provided for controlling the temperatures.  The internal thermocouples may be dispensed with when the relation between internal and external temperatures has been established. Quartz nutrient is placed in the bottom of the vessel which is then filled to the desired degree with the carbonate solution and a quartz seed 78 suspended in the upper part of the vessel from the sealing plug 16.  A modified form of pressure vessel is shown and described having a sealing plug with a large peripheral flange by which it is bolted to a corresponding flange on the pressure vessel.  This construction facilitates dissipation of heat from the upper part of the vessel and allows a larger temperature gradient between nutrient and seed.

[Class 69 (ii)] [Also in Groups XXXVIII and XXIV] The transmitter proper of an electric, pneumatic, hydraulic or mechanical control system is connected to an inertia member and a speed depen-. dent brake to delay its response and is coupled to the transmitting handle or other primary member through a yielding connection such that for a certain range of values of applied torque the coupling remains rigid and for higher values yields and transmits a constant torque independent of the amount of yield. In the arrangement shown in Fig. 1, the transmitter is provided with centrifugal brake segments B2 and a drum B1 to increase its inertia and is geared to a cam member C which is coupled to the transmitting handle H by a spring pressed roller R. If the handle is moved suddenly, the roller R leaves the notch in which it normally rests and thereafter the driving torque on the cam remains constant. Several yielding couplings associated with inertia members or brakes may be arranged in tandem with a section controlled in accordance with both speed and acceleration as indicated diagrammatically in Fig. 2 (not shown). Preferably the resistance to response is adjustable and may be provided by escapement mechanisms, eddy current brakes, oil brakes, dash pots &c.
