Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1928-04-11
Abstract: 315,292. Electrolux, Ltd., (Platen- Munters Refrigerating System Aktiebolag). April 11, 1928. Refrigerating, absorption machines for.- In continuous cycle systems containing an inert gas and wherein one or more of the heat delivering parts is cooled by vaporization of a liquid, the vapour produced from this liquid is used for circulating liquid of the system. The apparatus described comprises a generator 2, expulsion pipe 4, condenser 5, evaporator 6 and absorber 8. Inert gas and refrigerant vapour circulate in known manner through pipes 9, 7 between the absorber and the evaporator. The expulsion pipe passes through a chamber 12 containing liquefied refrigerant supplied from the condenser through a pipe 11. This liquid cools the pipe 4 to rectify the hot vapour from the generator, and the vapour produced passes down a pipe 13 to a nozzle 20 entering a pipe 14 in communication with the liquid space of the generator. The liquid is thereby raised to a vessel 15, whence it flows by a pipe 16 interchanger 10 and pipe 17 to the top of the absorber. The vapour passes through a pipe 18 to the liquid space of the absorber and is there absorbed. A wire wick may be placed in the pipe 11 to permit back flow of vapour from chamber 12 while liquid is flowing in, or the pipe 11 may lead through a seal into a separate chamber connected to the chamber 12 and having a vent pipe to the condenser. The vapour after moving the liquid may be condensed and returned to the chamber 12, instead of being absorbed, and a linuid other than the refrigerant may be used.

Title: An improved method of, and means for, measuring distances with the aid of sound
IPC: G01S15/12
Filed: 1922-04-20
Abstract: 180,646. Atlas-Werke Akt.-Ges. May 24, 1921, [Convention date]. Determ.ining bearings and distances acoustically.-In a method of measuring distances with the aid of sound, particularly for depth sounding, impulses are sent out at such intervals that the emission of an impulse, or its arrival at a receiving device, synchronises with the arrival of a preceding impulse at the end of the distance to be measured so that the number of impulses per second is a measure of the distance. A sound-transmitter S, Fig. 4, which may be a tapper, an electrically-operated diaphragm transmitter, or a number of successive explosions, is actuated once in each revolution of a contact device M. The receivers E1, E2 at the extremities of the distance to be measured act through the transformers J1, J2 on a common indicating instrument G which shows synchronism of the arrival of sound impulses by a maximum or minimum indication. The two receivers mav be on opposite sides of a ship with a sound screen between and the received sounds be reflected from the bottom. The binaural method may be used, as the sound appears to come from the side of the observer on which the receiver first actuated is situated. In a modification, Fig. 5, a single receiver E2 is used and when an impulse is emitted from S, a direct current impulse acts through a parallel circuit on the instrument G, the effect of this impulse being adjusted by means of a resistance W to be equal to that of an impulse received by the receiver E2.

Abstract: 1415854 Transferring articles between conveyers CADBURY Ltd 27 Feb 1973 [10 March 1972] 11297/72 Heading B8A Articles such as slabs of chocolate 11 in transversely misaligned rows on a conveyer belt 10, are brought into transverse alignment by engaging a stop bar 16. The latter is raised (to permit the aligned row to proceed) when the last slab of a row ceases to obturate a photo-electric gate PD5. The row is then halted by a stop bar 15. A conveyer belt 8, transversely above the belt 10 is driven by a motor which is energized when a switch (D3) (Fig. 3, not shown) is energized by the action of pressure against the stop 15 of all the slabs of the row. The belt 8 has two pushers 7 which project from the belt, so that one of them engages one end of the aligned rows of slabs and feeds the row on to a take-away conveyer belt 14. A photo-electric gate PD4 gives an indication if the conveyer 14 is full and cannot accept further slabs from the conveyer 10, and the drive motor of the conveyer belt 8 is then stopped. Two further photo-electric gates PD1 and PD2, operate to detect undue misalignment of an approaching row. If they are simultaneously obturated by such a row, the latter is permitted to pass under the stop 15, either to a further transfer belt 8, or to a collection point. A manual switch 17 enables the stop 15 to be raised, if for any other reason, transfer to the belt 14 in Fig. 1 is not desired. A logic and circuit diagram for automatically controlling the above operations (Fig. 3, not shown), is described.

Title: A process for effecting hydrogenation and dehydrogenation of organic compounds
IPC: C07C5/03
Filed: 1936-04-20
Abstract: The hydrogenation of olefines possessing an unsaturated tertiary carbon atom and the dehydrogenation of monohydric primary alcohols containing at least two carbon atoms or of secondary alcohols are simultaneously effected by heating these substances together in presence of a hydrogenation catalyst.  The temperature should not substantially exceed 500 DEG  C., and the operation may be performed under pressure.  For example, diisobutylene and isopropyl alcohol may be heated to 250 DEG  C. at 600 lb. per sq. in. in presence of a nickel catalyst, whereby iso-octane and acetone are produced.  The invention permits of the hydrogenation of olefines containing sulphur compounds without poisoning of the catalyst, since these impurities are diluted by the addition of the sulphur-free alcohols.  In a modification, the alcohols are separately dehydrogenated and the resulting mixture of aldehydes or ketones and hydrogen is reacted with olefines in presence of a hydrogenation catalyst.  The hydrogen is thereby removed and the separation of the products of dehydrogenation is facilitated. Specification 404,643 is referred to. The Specification, as open to inspection under Sect. 91 comprises also the treatment of any compound having an olefinic linkage with any organic oxy-compound capable of being dehydrogenated under the conditions of the process.  This subject-matter does not appear in the Specification as accepted.

[Also in Division H3] In an amplitude modulation system, the D.C. power supply for the carrier frequency amplifier is derived from a rectifier fed from an A.C. source the frequency of which is high compared with the modulation frequency, and the level of the D.C. is controlled by the modulation signal. The A.C. input to the rectifier may be derived from a transistor or thyristor inverter of either the controlled or free-running type. In one embodiment, Fig. 4, a controlled transistor inverter 5, 6 provides the A.C. input to a rectifier comprising two thyristors 10, 11. The D.C. output is controlled by varying the on/off ratio of the two thyristors by means of the modulation signal which is applied to two transistors 48, 49 which vary the charge time of capacitors 8, 12. In a modification, Fig. 1 (not shown), both thyristors are controlled from a single transistor. In an alternative arrangement, Fig. 3 (not shown), diodes are used in the rectifier, and the D.C. level is controlled by pulse-width modulating the inverter control signal.
