Filed: 1924-05-10
Abstract: 224,587. Horton, S., and Adams, J. May 10, 1924. Moving-chamber apparatus.-Relates to the construction in which a single measuring chamber a is rigidly attached to and surrounds a sleeve c adapted to receive a hollow taper plug d divided lengthwise into inlet and outlet portions and having an air tube h extending down the central bore into the supply passage d<3>, the sleeve and plug being formed with the necessary transverse passages to fill and empty the measuring chamber alternately from part rotation of the combined chamber and sleeve about the plug, and consists in forming the metal chamber with tubular ends within which fit and are fixed without mechanical means the upper and lower ends of the sleeve. With the parts in the position shown, liquid from the bottle or container into which the cork j fits, flows into the chamber a through the passage d' and opening c<3> until the vent c<5> is sealed. The combined sleeve and container are now rotated about the plug to an extent determined by a stop pin i and plate c<6>, when the outlet port f is brought into register with an opening c<4> in the sleeve while the vent c<5> registers with an elongated passage in the plug communicating with the atmosphere. The tubular ends of the chamber are soldered to the sleeve.

[Also in Division G3] An electrical apparatus for measuring the mean temperature and thereby the heat content of a liquid in a tank 1 comprises a number of  serially connected temperature sensitive resistors 4-7 arranged throughout the height of the tank 1, the resistors being connected to source 15 of  constant voltage and to a tapped potentiometer 12, a tapping 13 on which potentiometer supplies an indicating device such as a glow tube 14, the amount of illumination in the tube indicating the  heat content of the liquid. The resistors 4-7 may be either of the negative or positive temperature coefficient type and may also be semi-conductor devices. Fixed resistors 8-11 may be associated with the resistors 4-7 to linearise the indication in the glow tube 14. Alternatively the indicator may be of the kind having a rotatable element rotation of which is caused by a bi-metal element heated by a coil supplied from the potentiometer 12.

Title: Improvements in and relating to impedance relays
IPC: H01H53/10
Filed: 1943-12-08
Abstract: 600,242. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 8, 1943, No. 20494. Convention date, Dec. 12, 1942. [Class 38 (v)] An impedance relay has a moving contact member 7 pulled in opposite directions by two electromagnetic devices responsive respectively to current and voltage of an A.C. circuit. The current unit is of the induction motor type having a non-magnetic metallic cylinder 17 fixed to the arm 7 and movable between a magnetic stator 16 and a series of poles 12, 13 having energizing windings 14 and flux-displacing windings 15. The latter have in series with them a capacitance 22 and resistance 23 to provide a damping or dead-beat circuit which prevents false operation of the relay on transient currents. The torque on the rotor 17 is proportional to the square of the current. The voltage-responsive unit consists of a magnet 8 and armature 10, the magnet being energized with D.C. current by means of the potential transformer 26, a potentiometer 28 and a rectifier 27. It is found that the copper oxide rectifier 27 makes the torque on the member 7 substantially proportional to the square of the voltage. When the opposing torques on the contact member 7 are substantially equal, E<2>/I<2> will equal a constant. In other words, the condition of equality corresponds to a definite value of E<2>/I<2>,i.e. of E/I, i.e. of the impedance, and since the relay operates immediately "equality '' is departed from, it responds in effect to a definite impedance and is independent of any particular voltage or current. Specification 292,110, [Class 38 (iv)], is referred to.

IPC: B01J31/22
Filed: 1962-05-29
Abstract: Propynol and butynediol are simultaneously prepared by reacting acetylene with formaldehyde in the liquid phase in the presence of a cuprous acetylide catalyst on a base of silica gel or aluminium silicate containing from 10 to 20% by weight of copper, 2 to 9% by weight of bismuth and treated with 0.01 to 0.25 equivalent of an alkali or alkaline earth metal bromide or iodide per kilogram of the said catalyst.  The catalyst may be treated with the metal halide prior or subsequent to the formation of cuprous acetylide and in the latter case the metal halide may be present in solution in the reaction medium. The reaction medium may be an aqueous medium or may be an organic system comprising, for example, acetone or tetrahydrofuran.  Preferred metal halides are sodium iodide, potassium iodide, potassium bromide, lithium iodide and strontium iodide.  Examples are given.  A comparative example illustrates the use of a catalyst which has not been treated with an alkali or alkaline earth metal bromide or iodide.

One end of the spring 46 forms a combined skid and belt guard 48 and the other end 50 normally engages a latch detent 51, and during the insertion of the converter 41 through the port 38 at the front of the cleaner a lower cam surface of a leading converter abutment 44 rotates the end 50 clockwise within a bearing 47 until they clear one another, and then the lower cam surface of a trailing abutment 43 rotates the end 50 counter clockwise so as to disengage the end 50 from the detent 51 and thereafter tensions the spring 46 sufficiently to allow it to raise the nozzle 11 on releasing the downward pressure on the converter 41. The latter is automatically latched in its ports 38. During withdrawal of the converter which has a forked end to straddle the fan shaft, the trailing abutment 43 recedes from the end 50 and the leading abutment then engages it to effect latching before cleaning it.
