Title: Temperature-sensing probes
IPC: G01K13/02
Filed: 1973-03-26
Abstract: 1461574 Temperature sensing devices SMITHS INDUSTRIES Ltd 22 March 1974 [26 March 1973] 14480/73 Heading H1K A temperature sensing probe comprises a tubular shell within one end of which a sensing element is located and a cable for making electrical connection to the element extending therefrom lengthwise of the probe along a helical path against the inside surface of the shell and being bonded thereto at least at spaced points along that path. As described the element is a thermocouple formed by joining inner conductors 10, 11 of a metal-sheathed magnesium oxide insulated cable 12 (Fig. 1). In manufacture, after forming the couple and sealing the sheath at a point beyond it, the cable is wound to the required form on a mandrel, coated with brazing material, and push-fitted into steel tube 1. A cup-shaped element 7, a cap 17 apertured as shown and seal 13 are put into position and the assembly heated to 1075‹ C. to braze the cable and the cap and element 7 to the shell to give a vibration-resistant construction. Thermal stresses are reduced by making shell 1 and the cable sheath of expansion coefficient matched materials, e.g. specified nickel chromium and nickel-chromium-iron alloy respectively, the inner conductors of the cable preferably being of nickel-chromium and nickelaluminium alloy respectively. Adhesive placed at spaced points along the cable may be used instead of brazing. A cable with a plurality of pairs of inner conductors, or a plurality of cables each with one pair, may be used to provide a number of thermocouples and in an alternative form the probe shell or sheath of the cable may constitute one limb of the couple or couples.

Title: Catalytic conversion at high coke levels on catalyst
IPC: C10G11/02
Filed: 1965-04-06
Abstract: In a process for cracking a hydrocarbon charge employing a crystalline aluminosilicate catalyst, when the amount of coke deposited upon the catalyst is 15% of the weight of the crystalline aluminosilicate which the catalyst comprises, the catalyst is subjected to regeneration to decrease that amount of coke to a minimum of 1% of said weight, the regenerated catalyst being employed for cracking further hydrocarbon charge.  The catalyst may be a natural or synthetic molecular sieve which may be base-exchanged to replace alkali metal, e.g. by H or rare earths.  Cracking temperatures may be 550 DEG  to 1100 DEG  F., at a LHSV of 4 to 500. In examples, gasoline is produced from gas oil.

Filed: 1938-05-16
Abstract: 514,789. Field control of D.C. motors; varying E.M.F. ENGLISH ELECTRIC CO., Ltd., and CORNER, H. S. POUND-. May 16, 1938, No. 14552. [Class 38 (iii)] One or more compound-wound motors 1, 2, are connected to a source in series with a machine 3 which bucks or boosts the supply voltage and each motor has an additional field winding 1d, 2d, which is connected in series with at least one motor and in parallel with the booster. Thus with a decrease of motor speed the excitation increases, and vice versa. The field windings 1d, 2d, may be used only during regenerative braking of the motors. The machine 3, which is driven by a machine 4, may be excited as described in Specifications 509,041 and 509,884 so as to accelerate and regeneratively brake the motors with a predetermined armature current. When the motors have been accelerated up to the supply voltage they may be transferred to the supply and subsequently retransferred as described in Specification 509,138 and while they are connected only to the external source the machine 3 may supply the separately excited fields 1c and 2c, or the additional fields 1d and 2d, and a machine driven by the motors may control the excitation of the machine 3 to give a motor excitation which decreases with increase of speed as described in Specification 509,239. During regenerative braking switches 5 cut out sections 1b, 2b, of the motor series fields. The motors 1, 2, may be connected both on one side of the machine 3, and the fields ld, 2d, could be connected to the armature terminals of the machine 3.

Title: Apparatus for in-phase connection of a laod to an electric polyphase system.
IPC: H02H11/00
Filed: 1967-03-30
Abstract: 1,175,147. Protective arrangements. STENBERG-FLYGT A.B. 30 March, 1967 [7 April, 1966], No. 14621/67. Heading H2K. An arrangement for connecting a load 4, e.g. a rotating electric machine, to a polyphase system RST only when the phase sequence is correct, comprises a contactor 6 controlled by a phase-sequence sensing network C 1 , R 1  and a relay 3, with a thermistor 1 arranged to reduce the effects of current surges due to reactive components in the phase-sequence network and so prevent incorrect operation. In the arrangement shown, the coil of the relay 3 is energized when connection is made to a supply having incorrect phase-sequence. The relay opens contacts in series with the operating coil 6<SP>1</SP> of the contactor and closes contacts in a holding circuit for itself. This holding circuit includes the thermistor 1 which provides a delay before the current in the holding circuit becomes effective to hold the relay operated and so prevents the relay remaining operated if a current surge causes momentary operation. A thermistor 2 prevents the immediate operation of the contactor 6 when connection to the supply is first made. A thermal switch 5 opens its contacts, when the machine 4 is overheated due to overload, to disconnect the resistor R 1  of the phase-sequence network. This causes the relay 3 to be energized and the opening of the contactor 6, which remains open as the time constant of the thermistor 1 is lower than the reclosing time of the thermal switch 5.

Abstract: 769,915. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. May 21, 1954 [May 29, 1953], No. 15085/53. Class 40 (4). In a circuit arrangement for operating a particular combination of relays in response to an electrical condition applied to one of a plurality of conductors, each conductor is permanently connected to a unique combination of relays, and lock-out equipment is so arranged that when the condition is applied simultaneously to more than one of the conductors, two or more combinations of relays are operated, and each applies block-out conditions to the remainder until only one combination connected to one conductor remains operated and applies lock-out conditions to all the others, so that the subsequent application of the condition to any other conductor is ineffective to operate a combination of relays. The invention is applied to automatic telephone exchanges. Selecting idle outlet of wanted group, Fig. 3. The conductors are the test leads 1 to 16 of the selectors B, each of which will have battery connected thereto when the corresponding selector B is free, and ground when it is busy. In the absence of contacts S1, S2, S3, a combination of one relay of group Aar-Adr and one of group Bar-Bdr would be operated in respect of each free selector B; each relay in operating applies a disabling ground to all the other relays of its group, and eventually all the operated relays will release with the exception of one relay in each group, the operated combination being characteristic of one of the free selectors B. In order that the selector B indicated may be of the wanted group, the S contacts and their associated rectifiers are provided. It is assumed that there are three groups corresponding to the three S contacts S1, S2, S3, the test leads of the selectors B in each group being wired to the relevant S contact. The S contacts are all normally closed so as to disable all the relays, but when a selection is to be effected in a group, the corresponding S contact is opened to remove the disabling ground from the test leads of that group. Any free selector B of that group can then operate its relay combination. Application of the invention to the interconnection of registers and a common translator is described.
