Title: Improvements relating to curing agents for thermosetting polymers
IPC: C08K5/00
Filed: 1962-03-21
Abstract: A curing agent for halogen-containing polymers (see Division C3) is produced by mixing dried bentonite clay with an imidazoline or polyimidazoline (defined in the Specification) at room temperature or above.  Alternatively the bentonite and polyimidazoline may be dispersed in a plasticizer which may be incorporated into the polymer mix.  The bentonite must not contain more water than is normally present and is preferably dried to remove surface water by heating either alone or with the polyimidazoline, to above 100 DEG  C. until constant weight is attained.  If a high molecular weight polyimidazoline is used then a solvent to fluidize same may be used for mixing with the bentonite and is later removed by evaporation. The amounts of clay and polyimidazoline are dependent upon the base exchange capacity of the clay which must be equal to or greater than that required to react with the number of molecules of polyimidazoline present. Oxides, sulphides and rates of of metals of Group IIb and IVa of the Periodic Table may be used to regulate the rate of curing when using the new complex.ALSO:The invention provides a process for curing halogen-containing polymers and a novel curing agent used in the process. The curing agent is a complex of dried bentonite clay and an imidazoline or polyimidazoline. The imidazoline has the formula <FORM:0979557/C3/1> in which R may be hydrogen, an alkyl or alkenyl group of 1-36 carbon atoms, or the group, <FORM:0979557/C3/2> and homologues thereof where n is 0-5 and R1 is hydrogen or a lower alkyl group of 1-5 carbon atoms, or R in the 1 position may represent an aliphatic ester group, R1 in the above may be hydrogen or an alkyl group of 1-5 carbon atoms. The polyimidazolines used have at least 2 of the above units. The polymers used include polyvinyl chloride and copolymers of vinylchloride with vinyl acetate, arcylates and maleates. The curing compositions may also contain conventional plasticizers and metallic compounds (oxides, sulphides) which regulate curing. Curing of the polymer compositions generally in at 140-210 DEG C. for 1-20 minutes.

Title: Improvements in apparatus for distant electric control
IPC: G08C21/00
Filed: 1930-04-11
Abstract: 355,216. Electric distant control systems. SLEEPER, M. B., 416, West 33rd Street, New York, U.S.A. April 11, 1930, No. 11598. [Class 40 (i).] In apparatus for reproducing movements at a distance, such as a writing telegraph, the movements at the transmitter send out varying numbers of audio-frequency impulses produced by generators of alternating current and the impulses are transmitted by wireless. The movements of the pencil 9, Fig. 2, at the transmitter are resolved into two perpendicular directions and operate two rods in these directions, one of which is shown at 4. Movements of the rod 4 cause the opening and closing of contacts 26 by notches 13 and hence the production of impulses by the oscillator 22 if the rod is travelling west, or 23, of a different frequency, if it is travelling east, the change-over being accomplished by a movable contact 17 in frictional contact with a worm-wheel 15 on the worm 14 on the rod 4. When the pencil is lifted, contacts 33 open and de-energize oscillator 36 of a third frequency. The impulses from oscillators 36, 22, 23 and the two of still different frequencies corresponding to north and south movements, modulate the wireless carrier wave by energizing a microphone in a loud-speaker circuit, the loud-speaker being in proximity to a modulating microphone. At the receiver the audiofrequency output from a receiver 46, Fig. 4, is fed to coils 50 .. 54 coupled to filter circuits 55, 60 .. 59, 64 tuned to the five modulating frequencies which feed relays for the operation of the reproducer. For the movement of the pencil in the north and south directions relays 70, 76 operate pawls 75, 77, engaging racks 74, 78. Other relays similarly move the pencil either east or west, and a relay 80, Fig. 5, operates an armature 81 to hold the recording pencil 82 on the paper while the contacts 33 are closed at the transmitter. The contacts 33 may be manually operated, and multiplied if desired to indicate the position of the pencil in a third dimension.

Abstract: 1425313 Power control circuit; control of A.C. motors BALDWIN & FRANCIS (HOLDINGS) Ltd 9 May 1973 [13 March 1972] 11619/72 Headings H2J and H2K A control circuit for controlling the supply of electric power to a load by means of a pilot relay comprises a circuit operative to detect the connection of a pilot diode in a pilot circuit and to detect the connection of a resistance in the pilot circuit, and operative to cause energization of the pilot relay to switch on the supply of electric power only in response to the connection of the pilot diode together with subsequent connection of the resistance. The circuit includes a first trigger circuit 5 which switches from one conduction state to the other only when the pilot diode 12 alone is connected in the pilot circuit, and a second trigger circuit 6 which switches continuously from one state to the other only when both the pilot diode 12 and the resistance 11 are connected in the pilot circuit, the circuit being operable to cause energization of the pilot relay 7 only if the first trigger circuit 5 has switched to the other state and the second trigger circuit 6 is switching continuously. The pilot relay 7 can be used for starting an electric motor, for example an induction motor, when a "start" button is pressed to change one arm 10 of a diode-resistance bridge 4 thus changing the states of bi-stable trigger circuits 5 and 6 which are followed by amplifier 33 which provides an output to operate the pilot relay 7 only when trigger circuits 5 and 6 are in their correct states for starting. In this way the pilot relay is not energized and the motor not started unless a pilot resistance is connected into circuit with the pilot diode after the starting contacts have been closed, so that accidental starting due to connection of a diode-to-earth circuit is prevented. In a second embodiment, Figs. 2A, 2B (not shown) the bi-stable circuits are replaced by oscillators, there being an interlock circuit, Fig. 2C (not shown), which can inhibit the supply of power to the first oscillator unless the interlock circuit is in a required condition, the inhibitory means comprising a third oscillatory circuit. Various operating conditions are discussed corresponding to the presence or absence of the pilot diode and pilot resistance or the instant of connection or disconnection of the pilot resistance.
