Title: Improvements relating to the dehydration of gases
IPC: F24F3/14
Filed: 1932-05-20
Abstract: 384,190. Drying gases. HUMPHREYS & GLASGOW, Ltd., Humglas House, Carlisle Place, London.-(Consolidated Gas Co. ; 130, East 15th Street, New York, U.S.A.) May 20, 1932, No. 14373. [Class 34 (i).] Air and gases, particularly fuel gases which are to be distributed in ordinary gas mains, are dehydrated by bringing them at normal temperatures into contact with supersaturated aqueous solutions of calcium chloride or other hygroscopic salts containing a sufficient amount of an organic substance such as glycerine interfering with the crystallization of the salt from the solution to prevent the latter solidifying under the conditions of use. Magnesium chloride, zinc chloride, or potassium acetate may be used instead of calcium chloride, and glycerine may be replaced by other non-volatile water-soluble organic substances, preferably of the polyhydric alcohol type, for example, ethylene glycol, sucrose, dextrin, dextrose, invert sugar, starch, gelatin, gum arabic, and glue. Compositions containing calcium chloride, glycerine, and water in which some of the calcium chloride has crystallized on cooling from a hot supersaturated solution in the form of finely divided crystals may he employed. The gases may be treated with the solutions in brush washers, in packed towers filled with coke or the like, or in other suitable types of washing or scrubbing apparatus. The treatment is preferably carried out in each washer on the countercurrent principle, and, if desired, several washers may be used in series on this principle. The dehydrating solutions may be regenerated after use by concentration in single or multiple effect vacuum evaporators. Gases may be dehvdrated by the new method to a relative humidity of about 15 per cent at 70‹ F., or until they possess a dew point of, for example, 30‹ F. According to an example, coal gas is dried by passing it at 75‹ F. through a vertical rotary washer fitted with cooling coils in which water is circulated at a rate sufficient to absorb the heat of the reaction, the dehydrating agent being a mixture containing 52 parts by weight of calcium chloride, 48 parts of water, and 25 parts of glycerine. Other examples of dehydrating solutions containing calcium chloride and glycerine are given.

Filed: 1933-05-20
Abstract: 418,912. Table games. SCHLUMBOHM, A., Neuenkirchen, Soltau, Hanover, Germany. May 20, 1933, No. 14679. [Class 132 (ii).] In a bagatelle-type game apparatus balls are projected by means of cues along inclined tracks in each of which a plurality of " catching bows " are located one behind another. The catching bows comprise suspended pivotal flaps and allow balls to pass up a track but prevent their return, the object being to project the balls so that they come to rest between bows according to scoring values associated therewith. The apparatus may be controlled by coin-freed clockwork mechanism. In one embodiment, balls n are projected along tracks c, Fig. 2, on the playing surface b, k, Figs. 1, 3 by cues or spring plungers, and either come to rest between two of the pivoted flaps g, or pass to the end of the tracks where they fall through an aperture d on to an inclined track e along which they roll to a stop bow p. The flaps g, are pivoted on bars h, Fig. 4, mounted in a common frame, and stop bars h<1> prevent an entrapped ball from returning along a track c. To release balls held by the flaps g or by the stop bow p, the part k of the ball tracks is retracted to the position shown in Fig. 3, by pulling a knob o<1>, Fig. 1, connected by a rod o and cord m (guided by pulleys) to the part k, whereupon the balls held by the catches g roll down the surface k on to the return track e, and balls held by the stop bow p are released as the stop bow rides up a fixed inclined surface q during retraction of part k, the released balls rolling to an aperture f. The member k is normally locked in its forward position, Fig. 1, by a lever, t, pivoted to the wall engaging in the notch in a lever r, Fig. 3, rigid with member k and is released for retraction, by a coin-freed mechanism. In another embodiment, the parts b, k, Fig. 8, of the ball tracks are immovable, and balls entrapped by the catches g, are released to return along the tracks k, b, by pulling a knob o<1> to raise the frame u carrying the catches g about its pivot v, through links w. This action may be coin-freed. In a further embodiment, the balls n in each track, Figs. 10 and 11, are projected by spring plungers y<1>, y<2> and the balls entrapped by the catches g are released by pulling a knob o<1> to rock the sprung portion k of the ball tracks about its pivot v<1> to the position shown dotted, when the balls run along their respective return tracks e as far as spring arms e<1> pivoted at y<6>. At the commencement of the playing surface b, each track c is replaced by two resilient wires y<5> and played balls n are forced up between these wires into playing position by rocking the arms e<1> to the " dotted position by means of an external handle. Coin-freed stopping means 4 may be provided for the balls in the return tracks e.

Title: Improvements in signalling apparatus for use in connection with marine and aerial navgation
IPC: G01S11/16
Filed: 1929-06-13
Abstract: 334,927. Stevenson, C. A., and Stevenson, D. A. June 13, 1929. Locating sounds. - Wireless signals from a transmitter T, and sound signals from a fog-horn H, or light signals, are produced simultaneously, the transmitter T being so modulated by the currents from a gramophone pick-up P, actuated by a record X, as to broadcast at intervals between the production of the signals, and in synchronism therewith, speech or other signals indicating the name of the transmitting station and/or its distance or direction with respect to the receiving station. The timing-wheel S, driven by an air-turbine from the air supply to the fog-horn, or otherwise (as is also the gramophone turntable) carries cams C, C for actuating the valve controlling the horn H, and a cam G which operates contacts K, K to set the gramophone in operation. Contacts K, K close the circuits of electro-magnets E<1>, E<2>, the former operating a clutch which couples a stationary turntable X to a moving turntable Xa, and the latter attracting the armature R which lifts the track U, and raises the roller V and the pick-up P, returning the latter to the edge of the turntable, on to which it is lowered when the contacts K, K open. The pick-up P is in series with a microphone M energized by sound from the horn H, and a note-magnifier A feeding the transmitter T. The operation of the system is as follows :-Just previous to the three blasts of the horn produced by cams C, the gramophone announces the name of the station and/or the code signal. Then the three blasts are picked up by the microphone and broadcast, and immediately the gramophone starts counting out miles and cables in speech, the timing being determined by the rate of travel of sound in air. On hearing the sound of the horn directly, the observer notes the count received by wireless and is thus given his distance. Other sound records may be substituted for the disc shown, other horn signals may be substituted for those already described, and the microphone M may be omitted. Specification 281,972 is referred to.
