Abstract: 545,114. Esters containing aluminium, tin and titanium; artificial resins. DU PONT DE NEMOURS & CO., E. I. Aug. 26, 1940, No. 13453. Convention date, Aug. 24, 1939. [Class 2 (iii)] Esters are prepared from # : γ-unsaturated primary alcohols and inorganic ortho acids of aluminium, tin and titanium. They may also be made by reacting the alcohols with esters of the ortho acids with more volatile alcohols. Specified unsaturated alcohols are : #-methallyl, allyl, furfuryl, crotonyl, tiglyl and propargyl alcohol, allene carbinol, 3- chlorbutene-2-ol-1, hexadiene-2 : 4-ol-1 and 3: 7- dimethyloctadiene-2:7-ol-1. The esters may be polymerized together with an organic compound containing the group : CH 2  join by the ethylenic bond to a carbon atom which is attached to at least one negative group. The esters containing aluminium and tin may be polymerized alone. Compounds with which the esters may be polymerized are: vinylchloride, asym : dichlorethylene, methylmethacrylate, styrene, methylacrylate, vinylpropionate, vinylthioacetate, ethylmethacrylate, vinylacrylate, cyclohexylmethacrylate, cyclohexylphenylmethacrylate, acrylonitrile, methacrylonitrile, methacrylicacid, methacrylicamide, N-alkyl acrylamide, vinylchloracetate, ethylacrylate, butylmethacrylate, octylmethacrylate, dodecylmethacrylate, #-chlorethylmethacrylate, methylvinylketone, ethylvinylether and butylvinyletber. In examples: (1) triethylaluminate is re-esterified with #- methallylalcohol in the presence of toluene the product is polymerized by itself and also together with methylmethacrylate ; (2) tetraethylstannate is re-esterified with #-methallylalcohol and polymerized with styrene or methylmethacrylate in the presence of benzoylperoxide ; the polymer with methylmethacrylate is given a white enamel-like surface by boiling in water ; (3) tetraethyl titanate is re-esterified with #-methallylalcohol ; the product is polymerized by heating in the presence of methylmethacrylate or vinylacetate and by heating in toluene solution with polyvinylacetate. Basic catalysts may be used for the esterification such as sodium alcoholates, calcium oxide and magnesium oxide. The interpolymers may be used in moulding powders. The Specification as open to inspection under Sect. 91 comprises the production of triallylaluminate by reacting allyl alcohol with aluminium in the presence of toluene and mercuric chloride and also the polymerization of the aluminium. tin and titanium esters either alone or with any polymeiizable substance. The latter include drying oils or other esters of drying oil acids with polyhydric alcohols, drying oil modified polyhydric alcoholpolycarboxylic acid resins and drying oil varnishes. The unsaturated esters may be added to coating compositions containing drying oil esters, and the polymers, which may be produced in granular condition, may be used in drying oil and drying oil modified polyhydric alcoholpolycarboxylic acid resin coating compositions. This subject-matter does not appear in the Specification as accepted.

Filed: 1974-03-27
Abstract: 1426845 Tape recorder control GRUNDIG EMV 27 March 1974 [27 March 1973] 13607/74 Heading H2J  Apparatus for controlling braking of a magnetic tape upon termination of a fastwinding operation comprises separate D.C. motors for the feed and take-up spool, and an arrangement whereby when a respective driving motor is switched off, the driven motor is excited to arrest tape movement, each motor being connected across the base and emitter of a transistor arranged to be conductive as long as the motor develops a back e.m.f. exceeding a predetermined value, the collector potential of each transistor controlling the driving voltage of the other motor through a logic circuit. In the embodiment shown, forward and reverse wind motors 1, 2 are controlled via respective transistors 3, 4 which are in turn controlled via respective NOR gates 5, 6 from manual switches 7, 8. In the rest position shown, outputs from gates 5, 6 are " 1 " and neither transistor 3 or 4 is conductive. If switch 7 is closed, output from gate 5 goes to " 0 " and transistor 3 is enabled to run the motor 1. At the same time transistor 9 will be turned on. This operation causes the upper and lower inputs of NOR gate 11 to change from " 0 ", " 1 " to " 1 ", " 0 " respectively and hence its output remains at " 0 ". However, when switch 7 is moved to off, transistor 3 is turned off and motor 1 will continue to rotate and provide a back e.m.f. to keep transistor 9 open. The output from gate 11 will thereby go to " 1 " and transistor 4 will be turned on to enable motor 2 which will having a braking effect on the tape. Motor 2 is driven in the opposite direction to the arrow by the tape itself and hence transistor 10 remains off. When the motor 1 stops, the output from gate 11 changes to zero and motor 2 also stops. In a modification, Fig. 2 (not shown), a bi-stable interconnected NOR circuit is provided to store an indication of the test switch 7 or 8 operated. This prevents unwanted motor movements if a switch is operated with no tape in the machine.

Title: Controllers for reversible electric motors
IPC: H02P7/00
Filed: 1930-05-06
Abstract: 352,613. Control of motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutter-Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) May 6, 1930, No. 13889. [Class 38 (iii).] Continuous reversals.-A motor A driving a planing-machine is reversed by plugging at each end of the stroke and thereafter accelerated by cutting-out series resistance in two stages. Should the means for effecting plugging fail to operate, a dynamic-braking circuit becomes operative, and should the supply voltage fail the motor is selfexcited during dynamic braking. During plugging and accelerating full field strength is used, but it is weakened for running. Normal starting and stopping is obtained by pushbutton control. The operation is briefly as follows. With normal line voltage contacts 9b, 9c are closed and contacts 9d, 9e are open, thus shunt field F3 is fully excited, both field rheostats 11, 12 being shorted. Depression of start pushbutton 19 causes, according to the position of controller 18 operated by the platen of the planer, closure of reversing switches 1, 2 or 3, 4. Thereafter resistance R1 and part of series field F1 is cut out, then resistance R2 is cut out and one of the rheostats 11, 12 is inserted in the shunt field circuit according to the direction of motion. At the end of the stroke the controller 18 is moved to its other position causing opening of the pair of reversing switches that were closed and the closing of the other pair so as to plug the motor, the resistance R1, R3 being reinserted in the armature circuit and the rheostat excluded from the field circuit, whereupon acceleration in the reverse direction proceeds as before. If either pair of reversing switches fail to complete the plugging connection, a switch 7 normally held open, closes with a time delay and completes a dynamic braking circuit through the resistance R3. Should the supply voltage fail, contacts 9b, 9c open and contacts 9d, 9e close to connect the shunt field F3 to the armature and switch 7 closes to complete the braking circuit. The field is connected in the appropriate direction to the armature through contacts 10b, 10c or 10d, 10e, these contacts being opened or closed in pairs after each reversal of the motor and according to the direction of rotation by means of a coil 10a. A stop pushbutton 20 or overload coil 29a controlling contacts 29 is operative to stop the motor. Inching pushbuttons 21, 22 for each direction of running, only cause acceleration steps to proceed as far as the cutting out the resistance R1 and field F1.

Abstract: 877,907. Electric selective signalling systems. MEFINA S.A. May 2, 1958 [May 9, 1957], No. 14077/58. Class 40 (1). In an electric digital-to-analogue converter incoming binary digital electric signals are converted into a corresponding axial movement of a member 25, Figs. 1 and 2, by a device comprising a continuously rotating shaft 1, Figs. 1 and 3, which rocks via eccentrics 2a a series to two-ended levers 3, Fig. 3, there being one lever for each digital position, a fixed shaft 8 which carries a series of pairs of levers 6, 7 coupled to corresponding levers 3 by links 4, 5, and a series of pairs of solenoids having series wound input coils 16a, 16<SP>1</SP>a, Fig. 3, and a normally energized biasing winding 17. In operation with no input signals the end 15 of the lever 7 is held fixed by the biasing current through coil 17 and so as the shaft 1 rotates lever 6 oscillates, whereas when a signal is applied to the input coils 16a, 16<SP>1</SP>a, the end 14 of the lever 6 is held fixed and lever 7 oscillates. Which of the two levers 6 and 7 oscillates is detected by a cam 9a (see also Fig. 5) which is either forced to the position shown in Fig. 3 if lever 6 is oscillating or to the symmetrically opposite position if lever 7 is oscillating, and this results in cam 9a either being moved axially along the shaft 8 or not by virtue of its cam profile 18, Fig. 5. Hence as a result of an applied pattern of input signals a series of cams 9, Fig. 1, are correspondingly positioned to give a resultant axial movement to a member 12 which is transmitted by rods 19, Fig. 2, pressing on levers 20, Figs. 1, 2, and 4, pivoted on pins 21 to protrusions 24, Fig. 1, in the member 25. Limited angular displacement of the member 25 is possible to vary the mechanical advantage of the coupling between the member 12 and the member 25.
