Title: Improvements in or relating to Fluids Flow Regulating Valves
IPC: F16K41/00
Filed: 1967-08-23
Abstract: 1,197,513. Valves. SARCO INTERNATIONAL CORP. 23 Aug., 1967 [30 Aug., 1966], No. 38912/67. Heading F2V. [Also in Division G3] The stem 26 of a regulating valve is guided with clearance 40 in a bush 28, and fluid from the main stream controlled by the valve, is induced to flow through the clearance to keep it clean. The fluid flowing through the valve seat 20 impinges directly on the end 46 of the bush and creates a higher pressure zone. A lower pressure zone in the region of a recess 48 in the bush communicates through passages 44 and a chamber 42 with the other end of the bush. In a modification, the chamber (42) is connected with a pipe (54), Fig. 4 (not shown), of which the other end opens toward the direction of flow to the valve outlet 14. This end of the pipe may alternatively be connected to a low pressure source external to the valve. An actuating diaphragm 30 communicates with the outlet through a restricted clearance 54. Pressure on the other side of the diaphragm is controlled by a pilot valve (not shown) which may be responsive to a pressure or temperature.

Title: Improvements in and relating to film-casting machines
IPC: B29C48/08
Filed: 1930-12-30
Abstract: Uniform films are obtained by depositing and spreading solution from a hopper on to a rotating drum, the surface of which has been made truly cylindrical under working conditions as regards temperature, evaporating the solvent and removing the film.  As shown in the drawings, a drum 4 is constructed from two spoke portions 14 mounted on a shaft 72 and a hollow rim portion 15 divided into compartments by cross ribs 5.  Heating or cooling fluid enters from the pipe 8 through the trunnion of the drum and along the hollow spokes 14 to the hollow rim portion 15.  Baffles 20 cause the fluid to pass backwards and forwards through the passages of the hollow rim and finally down spokes 14 on the other side of the drum and through the trunnion to an outlet pipe.  The outer periphery of the drum is made truly cylindrical by grinding under working conditions as regards temperature.  The drum is driven <PICT:0368886/IV/1> <PICT:0368886/IV/2> <PICT:0368886/IV/3> through a friction clutch and gearing by a motor which also drives the receiving spool 32.  The drum is enclosed in a lagged casing 33 provided with an inlet 34 for conditioned air and an outlet 35 for vapour.  The casing is provided with windows and doors for inspection and access to the film material.  The dried film is stripped from the casting surface by a rubber roller 46 which guides the film to a roller 47 adjustably mounted in a frame 48. The film passes over metal rollers 51 .. 54 mounted in adjustable bearings carried by a pair of rods 49 pivoted on the frame 48 whereby static electricity accumulated on the film is conducted away to the casing.  The weight of the rods and rollers is relieved by a roller 55 on a pivoted and counterweighted member 56. The film passes through a slot 43 in a curved sheet 44 constrained by the film to move in an arcuate path so that the casing 33 is closed at all times despite the variation in the size of the collecting roller 32 and thickness of the roll of wound film.  Cooling pipes may be disposed near the outlet for the film in order to minimize loss of solvent vapour.  The solution hopper 9 is supported by brackets and micrometer screws on a member 10 which is pivoted at 11 and supported at the other end by dependent lugs carrying rollers 13 which engage with the ends of the cylindrical surface of the drum.  The front side 61 of the hopper may be moved about a pivot by means of a nut 62 on the screw 63, so as to regulate the width of the extrusion orifice. In the continuous production of a cellulose acetate film, the surface of the drum may first be coated with a layer of gelatine.

Abstract: 1,068,508. Automatic control of temperature. BOFORS A.B. Sept.14, 1965 [Sept.14, 1964], No.39254/65. Heading G3R. In an automatic temperature control system for a heater 10 in a bath 6 for determining the melting point of a material 5 a bridge network, supplied with an alternating voltage VR, comprises a first arm having a resistor R p, varying in value with the temperature of the bath; a second arm having a resistor R s, set to a desired temperature, in series with a rheostat R v, driven to vary the desired temperature at a predetermined rate; a third arm with a resistor R F and a fourth arm having a phase-shifting combination of a capacitor C in series with a resistor R. The phase-relationship between a bridge voltage V F and the supply voltage VR is dependent on the difference between the desired and actual temperatures of the bath and pulses, derived by differentiating, amplifying and limiting in a unit 9, are used to switch silicon controlled rectifiers S. As the temperature of the bath approaches the desired value the phase shift approaches 180‹ so that heater current only flows for a small part of each half cycle. It is stated that every other pulse can be used to control a half-wave rectifier. In a modification, a basic phase-shift is provided by a choke in series with the supply to the bridge.

Title: Metal alkylboron compounds
IPC: C07F5/02
Filed: 1959-11-19
Abstract: Metal alkyl boron compounds are prepared by reacting metallic sodium or potassium with a trialkylborane in the presence of a polyether or tetrahydrofuran.  Triethyl borane is a preferred reactant but other alkyl boranes having up to 18 carbon atoms in each alkyl radical, or their complexes with ethers or amines, are also suitable.  Examples of polyethers are those of the formula RO-(CH2)n-OR where R is an organic radical and n is an integer from 1 to 10.  The dimethyl and diethyl ethers of diethylene glycol are preferred.  Temperatures in the range 0 DEG C. to 200 DEG C. are suitable but it is preferred to employ a temperature between the melting point of the metal and 160 DEG C.  An inert atmosphere of neon, nitrogen, krypton or argon is usually employed.  The product obtained may be subjected to reaction separately with an olefinically unsaturated hydrocarbon and hydrogen in either sequence, with the prior addition of additional sodium or potassium, if desired, to form higher alkylated sodium or potassium tetraalkylboron compounds.  It is preferred to effect the hydrogenation and reaction with olefine at 150 DEG C. to 225 DEG C. and 200 to 1,000 p.s.i.  It is preferable to employ at least 2 cycles of hydrogenation and olefination. Suitable olefines are ethylene, propylene, butylene, hexenes, octene-1, butadiene, cyclohexene, octadecylene-1, and styrene. The products may be reacted with an alkyl halide to produce a trialkylborone, or may be used for the reduction of alcohols or ketones.  The metal tetraalkylboron compounds, obtained complexed with the ether used, for example, sodium tetraethylboron complexed with the dimethyl ether of diethylene glycol may be reacted with a lead salt such as lead chloride or lead acetate to produce tetraalkyllead.

A rotary flowmeter comprising a cylindrical chamber 11, Fig. 1, through which the fluid whose mass flow-rate is to be measured is passed includes an impeller 27 having vanes 28 imparting angular momentum to the fluid to cause swirl, motor drive means 19 driving the impeller through a coupling spring 25 connected to the impeller and to a torque-sensing arrangement comprising a rotor 23, 29 responsive to the swirling movement of the fluid and a turbine T downstream of the torquesensing arrangement which is coupled to the motor drive means to assist said means in driving the impeller by the axial flow of fluid through the flowmeter. The mass flow-rate is proportional to the time interval between the passage of two points, one on the impeller and the other on the member 29 of the rotor. As shown, electromagnetic, pick-off parts 30a, 30b on the impeller and member 29 respectively co-operate with pickoffs 30<1>a, 30'b fixed to the casing.
