Title: Method of producing phosphorus-containing polymers
IPC: C07F9/32
Filed: 1961-09-12
Abstract: A method of producing linear or cross-linked phosphorus-containing polycondensates comprises the steps of reacting diphosphonites of the formula: <FORM:0945047/C3/1> with dihalogen compounds of the formula Hal-CH2-R1-CH2-Hal in a molar ratio of 1:0.9 to 1:1.1 by heating to between 100 DEG  and 200 DEG C., and distilling off the resulting alkyl halide, R representing a bivalent aliphatic radical or aromatic hydrocarbon radical, R1 is an alkyl group, R2 an alkyl or aryl group and R1 a bivalent aliphatic radical or aromatic hydrocarbon radical. Diphosphonites in which R1 and R2 represent variously ethyl and butyl and R represents tetra, penta- and hexamethylene or p-phenylene, and dihalogen compounds in which -CH2RCH2- represents ethylene, butylene, hexylene, p-xylylene, diethyl ether or diethyl sulphone residues are listed. Linear products are obtained by heating a mixture of the diphosphonite and the dihalogen compound in the molar ratio of 1:1, suitably at 100 DEG  to 140 DEG C. in a solvent such as toluene, xylene, dibutyl ether or nitrobenzene.  The products have the formula: <FORM:0945047/C3/2> in which X is a halogen or phosphor/organic group and can be converted to free polyphosphinic acids by boiling with acids or alkalis. The chain length of the products can be limited by departing from the 1:1 ratio.  The linear products are soluble in alcohols, chlorinated hydrocarbons, ethers, esters, ketones and benzene/tetrachlorethane mixture.  They can be cross-linked by heating (if sufficient halogen groups are present) or by reaction with metal oxides, diamines, diphenols, dihalogen hydrocarbons or other difunctional compounds.  Alternatively, the linear compounds can be stabilized by removing the halogen terminal groups by continued condensation or by reaction with, for example, phosphorous acid esters.  In Example (1) tetraethyl hexamethylene diphosphonite and p-xylylene dichloride are reacted together.  The product is cross-linked by heating alone at 200 DEG C., or by heating at 160 DEG -170 DEG C. with magnesium oxide or with hexamethylene diamine. A product stable up to 250 DEG C. is obtained by heating the first condensate with triethyl phosphite. In other examples there are reacted together (2) to (4) tetraethyl hexamethylene diphosphonite and (2) 1,4-dichlorobutane, (3) ethylene bromide, (4) b ,b 1-dichlorodiethyl ether; (5) tetraethyl pentamethylene diphosphonite and p-xylylene dichloride; (6) P,P1-diethyl-P,P1-diphenyl hexamethylene diphosphonite and p-xylylene dichloride.

Abstract: 447,277. Supply systems for consumption apparatus. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne.-(Assignees of Coates, F. ; Cranlea, Whitburn Road, Cleadon, Durham, and Vaux, A. ; 65, Shortmarket Street, Cape Town, South Africa) Nov. 14, 1934, No. 32773. Convention date, Feb. 17. [Class 38 (iv)] [See also Group XXXVII] An electric relay, which may be a thermal relay operated by alternating current, has a quick opening and closing of the contacts produced by forming them of magnetic material and disposing them between the poles of a permanent magnet so that the magnetic flux traverses them in series. As shown in Figs. 1 and 2, in a throe-phase supply A<1> ... A<3> the amount of current taken by a single phase lamp load B determines the connection or disconnection of a three phase water heater C by a switch K', the operating coil K of which is under the control of a thermally-operated relay E constructed according to the invention. The relay E comprises a U-shaped. currentcarrying bimetallic strip G fed from the secondary D<2> of a saturable transformer D, the primary D<1> of which is in series with the load. A second non-current-carrying bimetallic strip F is mounted alongside the strip G, the two strips bearing normally-engaged contacts J<1>,< >J2 of magnetic material. The engaging faces of these contacts are bevelled and a permanent magnet L is placed over them so that a magnetic flux M passes through the contacts following the dotted path in Fig. 2, and the contacts are magnetically attracted. If, however, an increase in the load B produces a heating of the strip G sufficient to overcome the attraction between the contacts J<1>, J<2>, they are then separated rapidly and the circuit of coil K between the neutral wire A and the phase A<1> is broken, the water heater C being thus automatically disconnected. On reduction of the load B, when the contacts J<1>, J<2> have approached each other sufficiently, a rapid closure of the contacts ensues and the coil K<1> is re-energized. The invention is applicable to relays other than of the thermallyoperated type, for example, to mechanically or electromagnetically-operated relays.

Title: Improvements relating to combined electricity supply and protection systems for operating colliery machines
IPC: H02H7/00
Filed: 1933-11-24
Abstract: 409,239. Protective cut-out arrangements. ELLISON, Ltd., G., and ANDERSON, J., Wellhead Lane Works, Perry Barr, Birmingham. Nov. 24, 1933, No. 32874. [Class 38 (v).] In colliery supply systems, wherein a machine k is connected to a controller over a cable e containing a pilot circuit f in which is a handoperated switch i at the machine for controlling the energization thereof, the pilot circuit is provided with a pair of parallel-connected relays of different impedance for controlling the controller and with an inherently, or automatically, variable choke y in series with both relays. The relay of lower impedance effects the normal control, and the other acts only when an abnormal condition occurs in the pilot circuit to prevent the latter from being closed independently of its switch i. The controlleractuating coil c is connected in series with the contact l of the low-impedance relay and with the normally-closed contact n of the highimpedance relay, the coils m, o of which are connected in parallel in the pilot circuit f, g of which g may be the cable-armouring. Relay n, o has at least three times as much impedance as relay l, m, and the latter is arranged to have a lower impedance when open than when closed. The choke y is designed to be magnetized at heavy currents to a point well above the knee of the magnetization curve and at normal currents to a point on or near the knee, the impedance at the latter point being therefore higher. Thus, normally, when i is closed, m closes l but n is insufficiently energized to open n, and the controller is closed by its coil c. Should a fault occur as at x, however, the coil o is sufficiently energized to open n and, whether i is closed or open, to prevent energization of the coil c. The automatically-variable choke used as an alternative to y may have a movable armature so that with the maximum air-gap the impedance is low. The initial current-rush on closing i attracts the armature and increases the choke impedance, the armature remaining attracted until i is reopened.

Title: Apparatus for controlling the magnitude of a variable condition
IPC: G05D23/22
Filed: 1957-10-23
Abstract: 832,734. Automatic control systems. BRISTOL CO. Oct. 23, 1957 [Dec. 19, 1956], No. 33021/57. Class 38 (4). The magnitude of a variable condition is controlled by the application of a condition-affecting agent in response to a series of cyclical impulses whose duration is varied according to the deviation of said magnitude from a predetermined value. In a temperature control apparatus, Fig. 1, a thermocouple 15 in a vessel 10 is connected to a millivoltmeter having a moving coil 17 carrying a vane 18 varying the inductance of a coil 21 in the input to a control instrument 20. A resonant circuit 25, 26 in parallel with the coil 21 is cyclically varied by a constant speed motor 28. The output of the control instrument 20 is fed to a relay 22 which is actuated at a repetition rate determined by the resonant circuit and for a pulse duration determined by the position of the vane 18. The relay 22 actuates a solenoid 30 transferring a drive from an impeller 35 to an impeller 36. When the drive is transferred from an impeller a spring returns it to end stops 49a or 49b. The impellers drive in one direction only arms 40, 41 fixed to gears 42, 43 meshing with a sector gear 44 which is positioned in accordance with the on-off ratio of relay 22. A cam 46 carried by the sector gear 44 controls a valve 50 operating a slave valve 13 to vary the supply of temperature affecting agent through pipe 12 to the vessel. In a modification, Fig. 2, the valve 52 is connected to a lever 64, one end of which is positioned by the cam 45 and the other end by a cam 60 driven by a split-field motor 63 supplied through a relay 71 and resilient contacts 67, 68. The relay 71 is connected in parallel with the solenoid 30 and a contact 70 on an arm 69 fixed to the sector gear 40, connects the supply to the appropriate contact 67, 68 when the pulse on-off ratio, as represented by the position of sector gear 44, is outside of predetermined limits. In other modifications, the cams 45, 60 are replaced by linkages. In a further modification, the sector gear 44 drives a rheostat or other variable electric circuit element. Specifications 453,571 and 539,864 are referred to.

Abstract: 1,108,856. Bases for integrated circuits. AMP Inc. 22 July, 1966 [23 Aug., 1965], No. 33026/66. Heading H2E. [Also in Division B3] An electrical connector assembly for terminating the leads of an electric circuit module comprises a base 1 provided with a recess 2 for the module 14, and connectors 7 each of which has a crimping ferrule 10 integral with a contact portion 8 at one end extending through a countersunk hole 3, and an anchoring portion 9 at the other end secured in a recess 4 in the base 1. The contact portion 8 is also anchored to the base 1 by deforming a part 8a of the contact. The base 1 also has lugs 6 to locate the module and bosses 6<SP>1</SP> to locate the assembly in corresponding holes 19 in a printed circuit board 17 having eyelet receptacles 18 to receive the pins 8. The crimping ferrules 10 are basically U-shaped and have upper and lower (as shown) portions H, L which are flattened against each other and against the flat module leads 15 on crimping (see Division B3). This method allows the crimping pressure to be reduced and the base 1 may therefore act as the crimping anvil, for which purpose recesses 5 are provided in the base 1 to receive die teeth. Alternatively, a metal piece may be placed in a recess below the ferrule to act as the anvil (Fig. 7, not shown). The anchoring portion 9 of each connector 7 may take the form of a tube rivetted in a countersunk hole similar to that containing the pin 8 so that the connectors 7 may be arranged in a polarizing pattern.

Title: Method and apparatus for determining electric fields when carrying out prospecting operations

Filed: 1973-07-11
Abstract: 1431588 A/D conversion BOLIDEN AB 11 July 1973 [26 July 1972] 33111/73 Heading H3H Apparatus and method for carrying out prospecting operations for determining digitally the electric field produced in the earth by passing an A.C. current through the ground, is characterized by means wherein an A.C. voltage produced by the field is converted to a pulse train having a frequency proportional to the instantaneous voltage value and that pulses in this train are counted for a certain time, the direction of counting being determined by a signal indicative of the sign of the voltage and by a reference voltage having a known phase relationship with the A.C. passed to the ground. In the particular embodiment shown, three components of the voltage produced by the field are evaluated in three similar channels, namely an A.C. component in phase with the reference signal, an A.C. component 90 degrees out of phase with this reference, and a D.C. component. As shown, the voltage is picked up at 1 and passed to means 2 where at output 3 the frequency significant pulse-train is produced and provided as input to counters 20-22 in the respective channels, the output 4 producing a signal indicative of the sign of the input. Each counter provides output to a store 26-28, and thence to displays 32-34 via decoders 29- 31 and the channels all operate under the control of device 5. The first channel 20-32 is adapted to measure the A.C. component in phase with the reference signal and is provided with a signal 8, 14 from control device 5 indicative of up or down counting which signal is derived from an' EX-OR combining of the sign signal 4 and a reference signal input at 6. The counting period is derived via a frequency divider, the input of which is the reference signal and the differentiated output of which provides reset and read-in signals to counter 20 and store 26 respectively. The second channel 21-33 operates similarly but the EX- OR combination involves a reference signal 7 90 degrees out of phase with the first reference, and the counting interval is also derived from this reference. The last channel, adapted to measure D.C. components, operates directly from sign signal 4 and signal 6 for its counting interval control.
