Title: Purification of alkyl methacrylates
Inventor: STUTLER ATHEY CLIFTON JR
IPC: H01J29/68
Filed: 1968-12-20
Abstract: 1,235,208. Purification of alkyl methacrylates. EASTMAN KODAK CO. 20 Dec., 1968 [26 Dec., 1967], No. 60666/68. Heading C2C. Alkyl methacrylates which are contaminated with impurities having melting points below - 50‹ C. are purified by cooling a liquid mixture of said methacrylate and impurities so as to form a slurry of crystals of said methacrylate in a liquid medium richer in said impurities and causing said crystals to flow in a stream counter to a stream of liquid alkyl methacrylate, which liquid has been formed by melting previously formed crystals of alkyl methacrylate and which is at a temperature such that the crystals in said counter flowing stream partially melt and some of the liquid crystallizes and separating the liquid containing the remaining unmelted crystals of purified alkyl methacrylate. In the above process a portion of said unmelted crystals may be melted and the liquid recycled to said stream of liquid alkyl methacrylate; a portion of said counter-flowing stream, after said crystals have passed in counter-current therethrough, may be mixed with fresh contaminated alkyl methacrylate and the mixture cooled to form the slurry. The slurry preferably contains from 50-65% by wt. of solids and the crystals in said slurry suitably flow downwards in a vertical tower up which said stream of liquid alkyl methacrylate flows, the temperature of the stream at the bottom of the tower being 20-30‹ C. higher than the temperature at the top of the tower. Examples are given in which the alkyl methacrylate is methyl methacrylate (which may be obtained by the oxidative dehydrogenation of methyl isobutyrate) and the main impurity is methyl butyrate. Suitable flow diagrams for carrying out the above process are described.

Title: Change speed gear control
IPC: B60K3/04
Filed: 1970-12-23
Abstract: 1,270,907. Change-speed control. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. 23 Dec., 1970 [24 Dec., 1969], No. 61048/70. Heading F2D. A control for a change-speed transmission 8, on a motor-vehicle or other machine, driven by the working turbine 5 of a gas turbine set, is such that, during a manual shift, by a selector lever acting on a keyboard 22, turbine torque is reduced to zero by controlling at 14, through the usual accelerator pedal 11, the incidence of guide-vanes 4, fixed or rotating, between the working turbine 5 and compressor 1, permitting the superseded ratio to be disengaged, the shift to the new ratio being delayed until the speed of the turbine 5 is adjusted to synchronism by acting on the accelerator 11, and detected by a comparison signal from gear input and output speed sensors 25, 26, which prevents gear engagement until synchronism. The necessity for a separating clutch between the working turbine 5 and transmission 8 is thereby avoided. Turbine output torque is sensed at 24 as by axial thrust on a helical gear-wheel. The signals 24, 25, 26 are fed to a secondary control 23, signalling a primary control 12, which actuates the fuel control 13 and vane incidence control 14, in response also to signals 15, 20 representing inlet temperature and output pressure of the compressor 1 and gas-generator turbine 2, control pressure (18), gas generator and working turbine speeds, position of the accelerator pedal 11 and service brake 21. To start the vehicle the speed of the working turbine 5 is adjusted to zero by the vane control 14, to permit establishment of a gear from neutral, and subsequent start by accelerating the turbine.

Title: Re-cocking trigger device
IPC: F41A19/39
Filed: 1978-06-14
Abstract: A re-cocking trigger device for a large-calibre weapon has a percussion piece 3 coupled to a striker 11 and biassed in a forwards direction by a cocking spring 6. A shoulder 3a on percussion piece 3 normally engages a pawl 4. Turning of a trigger lever 15 in a clockwise direction rotates a shaft 13 to first advance a thrust sleeve 2 against a restoring spring 7 to free a path for percussion piece 3 (meanwhile held by pawl 4), and then causes lifting of pawl 4 to release piece 3 so that the latter impinges on striker 11. Re-cocking after firing and after the release of lever 15 is effected by restoring spring 7, but if striker 11 jams in the firing position or spring 7 breaks, striker 11 can be retracted, via sleeve 2 and piece 3, by turning lever 15 anticlockwise. <IMAGE>

Patent GB-2016750-A (GB)
Title: Electronic Voltage Regulator for Battery Charging Equipment
IPC: H02J7/14
Filed: 1979-02-28
Abstract: A battery charging circuit comprises two SCR's 2 and 3 arranged to control the charging of a battery 5 from the single phase winding 1 of a permanent magnet generator. In order to enable the circuit to operate even when the battery 5 is fully discharged, the bias for transistor 14 which controls the triggering of the SCR's is derived via respective resistor and diode network 31/32, 33/34 from the output terminals of the winding 1. When the battery voltage has reached a pre-set value, the potential at a point 9 exceeds the threshold of a Zener diode 10 which conducts, causing a transistor 11 to conduct. Consequently transistor 14 becomes non-conducting thereby blocking the SCR's 2, 3 and interrupting the battery charging current. <IMAGE>
