A number of heaters 11-14 having associated temperature-sensing devices 15-18 are controlled sequentially through selectors 19-21 by a common controller 22 having a reference source 23. If the temperature is abnormal an arrangement 24-26 pulses an appropriate bidirectional electromagnetic stepping switch 27- 29 which alters the tappings on a resistor. The arrangement 24-26 steps the selectors to the next position when the temperature is normal. The selectors 19-21 comprise pairs of bi-stablyconnected transistors, sequentially connected in a ring, so that a pulse to the ring opens a conducting pair and shuts the succeeding pair.

Title: Improvements in or relating to automatic reclosing mechanism for electric switches
IPC: H01H75/04
Filed: 1931-07-23
Abstract: 386,684. Protective cut-out arrangements; automatic circuit breakers. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WILSON, W., of General Electric Co., Witton, Birmingham. July 23, 1931, No. 21071. [Class 38 (v).] Electric-motor actuation; springs, arrangement of.-A mechanism for automatically reclosing a switch, shown as mounted on a pole, comprises a motor 5 rotating a crank wheel 8 through reduction gearing, the wheel 8 acting through a rod 9 on a lever 2 which is rotatable clockwise through 120‹ to stress a spring (not shown), which thereupon recloses the switch and also rotates the lever 2 in the reverse direction. The rod 9 has a lost motion connection with the wheel 8 such that, after 180‹ rotation of the latter, the rod moves by itself under the return action of the lever 2. When the switch opens, a contact 1 closes to energize the motor 5 from the conductors 6, the circuit including a rotatable conducting segment 14 and finger 12. When the wheel 8 is rotated by the motor, an alternative circuit for the motor is made by conducting ring 10 and finger 11, so that the motor continues to rotate until the wheel 8 has made one revolution and closed the switch; thereby opening the contact 1. Towards the end of the movement of wheel 8, a pin 24 thereon engages an arm 21 and, by means of a pawl 22, steps the disc 13 on a tooth, a pawl (not shown) retaining it in this position. If the switch remains closed, the relay 18, which was energized with motor 5, is de-energized simultaneously with the motor, thus allowing its contacts 17 to close the circuit through finger 15 and segment 14 of a resetting coil 16, which raises the two pawls, so that the disc 13 is returned to its original position by the spring 19. If the switch opens again after being closed, the contact 1 recloses and prevents the contacts 17 closing and resetting the parts, the pin 24 stepping the disc 13 another tooth. After a predetermined number of attempts to reclose, the segment 14 passes from under the finger 12 and further attempts are prevented. The first attempt at reclosure takes place after a shorter interval than the subsequent attempts, the intervals depending on the speed of the motor.

Patent GB-920807-A (GB)
Title: Process for preparing organophosphorus halides
IPC: C07F9/52
Filed: 1959-06-19
Abstract: An alkyl phosphorus halide having the general formula RnPX(3-n) in which R is an alkyl group having not more than 3 carbon atoms, X is a halogen atom and n is 1 or 2 is obtained by treating phosphorus at an elevated temperature with an alkyl halide having not more than 3 carbon atoms in the alkyl group and continuously removing the reaction products from the reaction zone.  The alkyl halide is preferably a bromide, chloride, or iodide and the phosphorus is preferably red phosphorus in finely divided form, although yellow, violet or black phosphorus can also be used.  The reaction may be carried out in the presence or absence of a metal catalyst, e.g. Cu, Ni, Ag, Sn, Sb, or their alloys with copper.  The reaction may be effected by passing the alkyl halide in gaseous or vapour form over and through a contact mass comprising a uniform mixture of phosphorus and a metal catalyst, heating the mixture at a temperature sufficiently high to effect reaction and continuously removing the alkyl phosphorus halide formed.  Suitable contact masses may be obtained by mixing powdered phosphorus and the metal catalyst with an inert carrier, e.g. glass wool, asbestos wool or pumice, and heating the mixture at elevated temperature, preferably at from 200 DEG C. to the sublimation point of phosphorus under reducing conditions (e.g. in a hydrogen atmosphere) for a sufficient period to increase the catalytic activity of the metal. The reaction between the alkyl halide and phosphorus is preferably effected at atmospheric pressure but higher or lower pressures can be used.  The process may be carried out as a fixed bed operation or the phosphorus and catalyst may be in fluidised form in the reactant gases.  When gaseous methyl chloride or methyl bromide is reacted with phosphorus in the presence of a copper catalyst to yield methyl phosphorus dichloride or dibromide suitable reaction temperatures are 340 to 380 DEG C. and 320 to 360 DEG C. respectively.  The vapour of the alkyl halide may be brought into contact with the heated phosphorus admixed with hydrogen or an inert gas such as nitrogen or methane.  Examples are given and specified products obtainable by the process are (CH3)2PCl, CH3PCl2, (CH3)2PBr, CH3PBr2, CH3PI2, C2H5PCl2, (C2H5)2PCl, (C2H5)2PBr, C2H5PBr2, C2H5PI2, n-C3H7PBr2, (n-C3H7)2PBr, n-C3H7PI2, iso-C3H7PBr2, (iso-C3H7)2PBr and iso-C3H7PCl2.  Many of the products are useful as biological toxicants, lubricating oil additives or plasticizers and the mixtures obtained by the process may be reacted with organic magnesium bromides and methyl iodide to form tri-organophosphines.

As described, the apparatus has two grinding/polishing heads 7 on shafts 8 connected by flexible joints 10 to the shafts of gears 6 which are rotatably mounted in the cage 4 and connected by intermediate gears 5 to a gear 2 attached to a coupling member 1 of the drive shaft. A shield 9 is secured to the cage and has slots permitting radial movement under centrifugal action of the shafts 8 which may be flexible. When the coupling is rotated, the cage 4 and heads 7 rotate about the axis of the coupling until the heads engage the tube wall and the resistance causes an epicyclic effect and the heads to counter-rotate about their axes, the mass of the cage assembly, being greater than that of the grinding head shaft assemblies, causing, the unit to rotate freely about the axis of the coupling while the grinding heads counter-rotate.

A fifth beater may be arranged below the second beater and be rotatable in a sense opposite to the drum's to receive the crop mass from the first beater and thrust it back to a lower part of the drum, after which the mass is carried up by the drum to the third beater. The crop mass is fed into the drum by a conveyor 28 and the hulled crop falls through the screen onto a laterally running belt 105 whence it passes onto an inclined belt 110 and a belt 120. Trash falling onto the belt 105 with the hulled crop is delivered sideways out of the machine whilst the trash retained within the drum is discharged via a conveyor 130. The conveyors and beaters are driven by respective hydraulic motors and the inclination of the unit 30 is varied by use of adjustable rear ground wheels 16 and hydraulic jack 22. Beater Arrangement. Several arrangements of the beaters are disclosed.

Crop e.g. peas is separated from trash e.g. pods at each impact between the crop mass and paddles of the various beaters on the screen's inner surface. In a further embodiment, the second fifth and fourth beaters are respectively angularly displaced by 30‹, 120‹ and 270 from a vertically extending radial line in the direction of rotation of the drum.

The actuator current flows through a shunt 42 whose voltage drop controls the conductivity of a transistor 47. The collector current of this transistor normally flows via a resistor 65 and the transistor 54, but if the current becomes too great the voltage drop across the resistor 65 causes a Zener diode 51 to break down, switching transistor 53 on and hence transistor 54 off. The feedback provided by resistor 65 ensures that the switching action is rapid and self-latching. If the voltage between the supply lines 39, 32 becomes too low, a Zener diode 64 ceases to conduct, thereby switching a transistor 61 off and hence transistor 57 on to short-circuit the resistor 55. A regulator 38, 41 interrupts the supply if the battery voltage is too high.
