Abstract: 438,797. Wireless receiving-apparatus. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Wheeler, H. A. ; 18, Melbourne Road, Great Neck, and Case, N. P. ; 26, 212th Street, Bayside, both in New York, U.S.A.) May 22, 1934, No. 15260. Convention date, Nov. 7, 1933. [Class 40 (v)] In a wireless receiver having a selectivity control for adjusting the band - width, means are provided operative upon adjustment of the tuning to adjust the selectivity control to minimum band width. Interlocking means may be provided between the tuning and selectivity controls so that the former is operative only when the latter is adjusted for minimum hand width. Fig. 1 shows a high-frequency amplifier 23, frequency changer 24 and intermediatefrequency amplifiers 47, 53 in which the coupling of coils 21, 48, 55 is adjustable to vary selectivity preferable from one half to twice optimum coupling. The input transformer 14 is described in Specification 370,768 and the preselector 13 is described in Specification 383,668. The construction of the frequency changer 24 is described in Specification 435,383 and the circuit in Specification 436,940. The automatic volume control valve 83, serves as an amplifier at intermediate frequency and the tuning of the transformer 86 is flatter than that of transformers 46, 54. A diode detector develops the automatic volume control voltage across resistances 92, 93. The application of the automatic volume control to the radio frequency amplifier and visual tuning arrangement are described in Specification 293,462, [Class 40 (v)], and the control of the audio frequency amplifier is described in Specification 402,981, Figs. 3, 4 show the construction of the receiver Fig. 3, showing the mechanical arrangement for tuning control by gear wheel 104 and selectivity control by the bell-crank lever 108 which adjusts the coupling of coils 21, 48, 55. The tuning control being operative only when the selectivity is high. Fig. 4 shows the volume control 80 which is operated by the same shaft 127 as the tone control 82 with rotary and axial movement respectively. Specifications 438,831 and 438,832 also are referred to.

Patent GB-365946-A (GB)
Title: Compressed-air-operated sound producing installation for railways
IPC: B61L5/20
Filed: 1931-05-29
Abstract: 365,946. Railway warning signals. KRUPP GERNIANIAWERFT AKT.-GES., F., Gaarden, Kiel, Germany. May 29, 1931, No. 15750. Convention date, June 5, 1930. [Class 105.] A compressed air sound-signalling apparatus is actuated by the depression of a treadle 1 which carries at its.inner end a pawl device 18 whereby a contact 12 on a pivoted member 11 is momentarily swung out from between contact springs 13, 14 to cause a relay 16, normally held by a small current only, to drop its armature 26 which moves about a pivot 27. The armature 26 is formed with an escapement member 28 and when dropped releases a bellcrank lever 30 and thereby moves a valve 36 to vent a cylinder 39, a piston 46 in which descends and by means of linkages attached to the piston-rod 48 actuates firstly, a valve 67 to admit compressed air to a dual sound signal device 77, 78 and secondly, after an interval due to a lost-motion slot connection 51<1>, a valve 53 to admit compressed air to a resetting cylinder 60 the piston of which moves the bell-crank lever 30 to re-set the armature 26 and to set the valve 36 in the position to admit compressed air to the cylinder 39 whereby the whole apparatus is restored to its normal condition. The rail treadle 1 is provided with a dashpot device 7 and only returns to normal when the train has passed, the pawl device 18 permitting return of the inner end of the treadle over the tooth of the pivoted member 11. The non-return valve of the dashpot device carries an adjustable air relief valve 9. The apparatus is used for warning gangs working on the line and the armature 26 may be provided with contacts 22 .. 25 which break the ignition system of internal-combustion engines in use by the gang. Failure of the air pressure allows piston 46 to descend and close a contact 80 to sound an electric alarm 79. The working order of the apparatus may be tested by opening a contact 20 to de-energize the relay 16, the action then arising being the same as when the train depresses the treadle 1. The compressed air is supplied from a storage bottle 44.

Abstract: 568,345. Dish - washing machines. GUNN, A. J., and DOWSING CO. (ELECTRICAL MANUFACTURERS), Ltd. Sept. 25, 1943, No. 15763. [Class 138 (i)] In a dish-washing machine comprising a tank 1 arranged in a container 3 and which may be fitted with a detachable sprayer 5, as described in Specification 567,140, and with nested baskets 27, as described in Specification 566,489, water-circulating means is provided consisting of a pump 6 driven by a motor 7 under control of a switch 33, Fig. 2 (not shown), which is opened when the lid 28 is opened. The pump 6 normally draws cleansing liquid from a sump 2 and delivers to a discharge fitting 9, Fig. 3, and chamber 12 and thence via openings 14 to a discharge pipe 17 connected to the sprayer 5. The chamber 12 also connects to a pipe 18 leading to an outlet connected by a pipe 23, Fig. 5, to a nozzle 24 closed by a cap 25 held by a latch 26. A spring-closed piston valve 15 is kept open by the liquid pressure when the cap 25 is closed, but when it is desired to empty the tank 1 the cap 25 is opened and the liquid withdrawn by the pump is discharged to waste by the pipe 24 and the valve 15 closes automatically under the action of the spring 16. To fill the tank, the pipe 24 is connected to a tap, and a float-controlled indicator tells when to close the tap. The lid 28 is provided with a downwardly extended flange 29, Fig. 2 (not shown), with a rim 31, and the tank 1 is provided with an inward flange 30 which extends across the rim 31 to form a splash trap. The sump 2 is fitted with an electric immerser 126 which may be controlled by a thermostat, and a filter may be fitted to the sump 2. The device is mounted on wheels 4, and by removing the sprayer 5 and the baskets 27 the device may be used as a domestic boiler. The valve 15 may be replaced by a positively operated valve. Knives protected as in Specification 565,113 may be cleaned in the machine.

Title: Improvements in the preparation of polyhydric alcohols
IPC: B01J39/04
Filed: 1960-05-05
Abstract: Polyhydric alcohol compositions obtained by the reduction of an aqueous saccharidic solution are purified by subjecting the aqueous polyhydric alcohol solution to a heat treatment at a temperature between 175 DEG  and 250 DEG C. for a period of from 10 minutes to 3 hours in the pH range of 4-7 cooling the solution, and subsequently passing the cooled solution through a cation-anion exchange system. The heat treatment may be applied directly to the reduction product or it may be applied to solutions which have already been subjected to preliminary purification for example by treatment with activated carbon and/or ion-exchange.  If a precipitate forms as a result of the heat treatment the solution is preferably filtered before passing it to the ion exchanger.
