Patent GB-983516-A (GB)
Title: Fluid epoxide compositions
IPC: C08G59/22
Filed: 1962-05-14
Abstract: A fluid composition curable with hardening agents comprises at least one polyepoxy compound and, as reactive diluent, at least one glycidyl ester of, either a saturated aliphatic monocarboxylic acid the COOH group of which is attached to a tertiary or quaternary carbon atom (Specification 936,808), or of a mixture of such an acid with a cycloaliphatic monocarboxylic acid.  Many known polyepoxides and known hardening agents are mentioned.  The acids whose glycidyl esters are employed may be prepared by reacting formic acid or carbon monoxide and water with olefins or with paraffins and hydrogen acceptors, using liquid acid catalysts.  Those used in the examples were prepared from olefins having 8-10 carbon atoms, with carbon monoxide and water in presence of aqueous phosphoric acid and BF3. The acids contained 9-11 carbon atoms and the COOH groups were attached to tertiary or quarternary carbon atoms in a ratio of about 1: 9. About 25% of cycloaliphatic acids were present in the product. Glycidyl esters were prepared from the sodium salt of the product and epichlorohydrin.  The polyepoxide used in the examples was a diglycidyle ther of 2,2-bis(4-hydroxyphenyl)-propane.  Examples illustrate the low viscosity and good pot life of the composition. Examples III, IV describe hardening with diethylene triamine, Example V with hexahydrophthalic anhydride and benzoyl dimethyl amine, and Example VI with methyl endomethylene tetrahydrophthalic anhydride and benzyl dimethyl amine.  In Example VII the mixture of polyepoxide and monoglycidyl esters was mixed with cracked bitumen and a curing agent prepared by reacting a glycidyl ester of branched monocarboxylic acids (C9-C11) with diethylene triamine, to form a bituminous paint. Example VIII is similarly for a paint but the bitumen is replaced by TiO2 and talcum.  Example IX is similar to VIII but also includes an amine plasticizer prepared by reacting the glycidyl ester of branched monocarboxylic acids with stearyl amine.  In Example X a glass fibre satin weave treated with a methacrylate chromic chloride finish was impregnated with a composition according to the invention and containing diethylene triamine as curing agent. The impregnated material was used to form a laminate, or could be wound round a pipe of rigid polyvinyl chloride.  The compositions may include conventional additives, e.g. other resins, or nitriles as diluents and may be used for the usual applications, e.g. coating, impregnating, sealing, foams, potting, casting and adhesives.

Title: Process and apparatus for the manufacture of metal grains, pellets or the like
IPC: B22F9/08
Filed: 1945-07-20
Abstract: 602,111. Casting shot in towers. MORANE, R., and MARTINET, R. July 20, 1945, No. 18649. Convention date, Jan. 20, 1943. [Class 83 (i)] Small pellets of lead arsenic alloy used in making lead steels, known under the Registered Trade Mark " Ledloy," or of other metal, are made by jolting a sieve containing a thin layer of such metal. The metal may flow from a pot 1 to a ladle 14, carried by a counterbalanced support 18, so that it falls when the depth of metal in the ladle exceeds a desired value, thus opening a switch which supplies current to a solenoid 12 and allowing a rod 6 to fall and close the valve 5. As soon as the depth in the ladle decreases substantially the ladle rises and closes the switch, thus re-opening the valve 5. The metal flows from the ladle 14 through calibrated removable nozzles 24 and pivoted shoots 26 to two sieves 25 which are rotated . through speed-reducing gearing 28, 34, 35 by a motor 37. Annular cams 38, Fig. 2, on the rims of the sieves engage rollers 39 connected to the shoots 26 oscillate these to distribute the metal. The sieves are mounted in a frame 33 which is pivoted at 41 and jarred by being raised by a cam 42, driven by the motor 37, and falling on a vertically-adjustable beam 43.

Patent GB-1423263-A (GB)
Title: Signal transmitters for connection by two wires to a load and supply source
IPC: G08C19/02
Filed: 1973-04-18
Abstract: 1423263 Two-wire telemetry ROSEMOUNT Inc 18 April 1973 [8 May 1972] 18808/73 Heading G1U Current drawn from a voltage source 10 is fed via a DC/DC converter 40 to power a circuit whose current is controlled to represent a physical condition to which sensor circuit 60 is sensitive, the sensor circuit 60 output being used to alter the current flow through a feedback resistor 62 to counteract the sensor circuit 60 output signal. In a telemetry system, a remote source 10 sends current through a load 11 representing an indicator, recorder or control element. Lines 13, 14 connect the source to a D.C. voltage regulator 20 and thence to a DC/DC converter 40. The secondary winding of the converter has two parts, independently rectified providing supply voltages for a sensor network bridge 60, differential amplifier 80 and a controlled current supply formed from transistors 83, 87. A thermocouple 75 is connected in series with the amplifier 80 across the Zener diode 65 stabilized bridge 60 and changes in temperature tend to alter the amplifier input (compared to a reference voltage from potentiometer 63) which causes the amplifier output to change the current flow through transistors 83, 87. The converter output voltages are arranged such that the current from the transistors and from the bridge flows through feedback resistor 62. This change in current alters the voltage at terminal 61 to counteract the change induced by the thermocouple. Potentiometer 63 allows the bridge to be zeroed at ambient temperature and potentiometer 71 provides sensitivity adjustment. The load current of the converter 40 is thus a function of the temperature sensed by the thermocouple 75 and this affects the converter oscillator frequency. The current drawn from the supply regulator 20 and thus source 10 consequently represents temperature, this being indicated or utilized by load 11. The use of separate supplies from the converter enables a larger voltage to power the integrated circuit amplifier 80 than appears at its inputs, thus optimizing its performance.
