Title: Composition containing vinyl or vinylidene halide polymers suitable for being worked-up to impact resistant products
Inventor: WATERMAN JACQUES ABRAHAM
IPC: C08L27/04
Filed: 1966-02-21
Abstract: A composition comprises (1) more than 50% by weight of at least one homopolymer and/or at least one copolymer of a vinyl and/or a vinylidene halide, and (2) a copolymer of which at least 45% by weight consists of at least one diene and at most 55% by weight of at least one ester of a bivalent or multivalent propylene carboxylic acid, at least one carboxyl group of which is attached to the non-doubly-bound carbon atom and at least one carboxyl group to a doubly-bound carbon atom, or an ester of a homologue of said carboxylic acid. Chlorinated polyvinyl chloride and copolymers of vinyl chloride with vinyl pivalate, or with vinyl esters of aliphatic carboxylic acids of 9-11 carbon atoms are included in (1).  The copolymer (2) may also comprises a vinyl aromatic, e.g. styrene.  The composition may be prepared by (i) mixing the latices obtained from the emulsion polymerization of the monomers, and coagulating, or (ii) mixing the polymer dispersion obtained by suspension polymerization with a latex prepared by emulsion polymerization, and coagulating, or (iii) mixing using dry polymers and, e.g. rolling mills, in which case part of the halide polymer may be incorporated at a relatively low temperature, e.g. 100 DEG  C., and the remainder at an elevated temperature, e.g. 180 DEG  C.  The diene-ester copolymers may be prepared by emulsion, in solution, in bulk, or in a liquid, possibly halogenated, hydrocarbon.  Several emulsifiers are used in the examples.  The copolymerization may be terminated by adding a solution of dimethyl dithiocarbamate, and the latices coagulated using ethanol.  As antioxidant, 1,3,5 - trimethyl - 2,4,6 - tri(3,5 - ditert -butyl-4-hydroxybenzyl) benzene may be used.  Suitable dienes are 1,3-butadiene, isoprene, dimethylbutadiene-1,3, and piperylene. Suitable acids are itaconic, glutaconic, aconitic and isaconitic acids.

Abstract: 416,274. Lathes. POPPENSIEKER, F., 39, Ubierring, Cologne, Germany. March 13, 1934, No. 7937. [Class 83 (iii).] In a multiple spindle automatic lathe the spindle drum is braked during indexing shortly before the final position and the forces arising in braking are caused to operate on the clamping device for the work bars. The braking of the spindle drum 6, Fig. 2, is effected by a bar 11 which straddles the bed and is supported on slides, the bar is adapted to engage collars 12 on the work clamping sleeves and when moved axially of the machine by means of the cam 7 and lever 10 it releases and clamps the work in the spindle which it engages and exerts a frictional braking action on the sides of the collar thus slowing down the drum towards the end of an indexing operation. Further cam and lever mechanism 13, 16, Fig. 1, operates through rack and segment gear a bar 20 similar to that described above for operating a reciprocating gripper feed. The cam grooves are arranged such that the bar 11 frees the clamping sleeve at the commencement of an indexing operation then the bar 20 feeds the work forward against a stop, finally the spindle drum is braked as it nears the end of the indexing operation and the work again securely clamped.

Title: Improvements relating to Electrically Operated Hoisting Machinery.
Inventor: ELLISON GEORGE
IPC: H02P3/18
Filed: 1918-05-16
Abstract: 126,800. Ellison, G., and Anderson, J. May 16, 1918. Electric plant.-In electrically driven hoisting machinery where the load is lowered against the effect produced by the motor, rotation of the motor is automatically stopped or prevented if the torque of the motor rises to a value sufficient to lift the load. In the arrangement shown in Fig. 1, the shaft of the winding drum d carries a frame lever g with switch arms l and a brake solenoid i. While the torque is insufficient to balance the load the latter descends, and the lever g swings from the arm on the right hand side to touch the contacts m and complete the circuit of the solenoid i, thereby holding the brake off. If the motor torque rises sufficiently, the arm swings over and the brake is put on by springs k. In a modification, a relay motor is used instead of the lever g. The rotor of the relay motor is geared to the main motor, and its stator is permitted a limited angular movement against the action of a spring. The relay stator carries an arm operating two sets of contacts in the circuits of the brake solenoid in the manner described with regard to Fig. 1, and the relay motor may also act to prevent excessive speeds. In another modification, the stator of the relay motor is allowed to rotate to control resistances in the rotor circuit in the main motor. In the modification shown in Fig. 4, the relay stator is fixed and its windings n are connected to the supply mains in the reverse direction to the stator winding of the main motor. If the main motor moves in the wrong direction for lowering, the current in the relay rotor o operates the electromagnet t and opens the switch u to put on the brake. The relay also acts to prevent excessive speed during lifting. In another modification, a detent is held by a spring in a position obstructing a ratchet wheel on the winding drum, and is pulled out from that position by a solenoid, during lifting. The solenoid is not energized when the controller is in the lowering position, and consequently the lever obstructs the drum if the motor tends to raise the load. In another modification, the detent instead of holding the drum, is rotated bv it to varv the resistance in the main motor circuit. Resistances may also be varied through clutches on the drum shaft, and may be put in or out by an electro-magnet operated by the current of the main rotor. In another modification, a wound rotor on the drum shaft has a pair of stators which can only rotate in opposite directions and which operate resistances.

Abstract: 1521221 Transistor amplifiers COMMISSARIAT A L'ENERGIE ATOMIQUE 2 March 1976 [4 March 1975] 08226/76 Heading H3T A circuit for stabilizing an amplifier against drift, e.g. for an X- or y-ray spectrometer, is connected as a negative feedback path between the output 8 and an input 10, Fig. 1, of the amplifier and comprises an amplification assembly 12 whose output is coupled to the input of a logical detection circuit 18 and to the input of an integrating circuit 22 via a first switch P a , the output of the integgrating circuit being coupled to the input 10, and the logical detection circuit 18 having a first output controlling switch P a  and a second output controlling a second switch P b  which couples the input of the integrating circuit 22 to earth, the logical detection circuit acting to open P a  and to close P b  when it receives a rapidly varying input, and to close P a  and to open P b  when it receives a slowly varying or continuous input. An embodiment of the logical detection circuit, Fig. 2, comprises two discriminators D h , D b  having bias voltages of 200 mV, applied across their inputs by two constant current circuits including transistors 34, 34<SP>1</SP>, thus establishing thresholds of 200 mV at which the discriminators switch from "0" to "1" output. If a positive signal having a sufficiently rapid rise is applied to input M (equivalent to 16 in Fig. 1) such that the P.D. across capacitors C 1 , C 1 <SP>1</SP> does not appreciably change, and if the signal amplitude is sufficient, the discriminator D h  will switch. Similarly a fast negative signal will switch D b . The arrangement of inverters 40,42 and NAND gate 44 is such that a "1" output from either or both of D h , D b  produces a "1" at the control of switch P a  and a "0", owing to the effect of the inverter 46, at the control of switch P b . Switches P a , P b  are arranged to be open when the control level is a " 1", and thus the desired action of the switches is produced. With sufficiently slow signals at M the P.D. across capacitors C 1 , C 1 <SP>1</SP> is able to change so that the discriminator threshold voltages are not reached. The switches P a , P b  may be integrated circuits including FET's. The circuit may reduce the drift for a temperature change of 20 C. from 450 mV to 5 mV, Fig. 3 (not shown). The time constant of the circuit is typically 10 Ás.
