Title: Improvements in or relating to combined gramophonic and wireless sound reproducing means
IPC: H04R1/16
Filed: 1924-02-01
Abstract: 232,710. Graham, E. A. Feb. 1, 1924. Gramophones combined with telephone receivers, for optional use as loud-speakers. - The sound duct of one reproducer is introduced into the duct of the other reproducer so that the outlet of the introduced duct is directly in the acoustic path and is also marginally free from the wall of the other duct. The Figure shows the duct f of the loud-speaking telephone g accommodated in an expanded portion d of a gramophone horn c. The introduced duct is preferably of conical, tapered or stream line form to prevent obstruction, and may be supported by a fin h of similar form. It may be circular, square or elliptical in cross-section. In a modification, the duct from the loud speaking telephone is mounted on a fixed portion of the tone arm, which thus carries both reproducing elements. Various other modifications are also described in the Specification.

Title: Improvements in snap-action electric switches
IPC: H01H13/60
Filed: 1939-01-26
Abstract: 519,605. Snap-action switches. SOLENTHALER, J. Jan. 26, 1939, No. 2691. Convention date, Jan. 26, 1938. [Class 38 (v)] Depression of a button 21 acts through a finger 19, resilient key 18 and roller 15<1> to depress an arm 5b of a three-armed lever 5 to turn a contact spindle 4, a snap-action being provided by a toggle spring 9. Spring 9 also acts through lever 8 and link 10 to press a roller 12 against a lever 16, and the tilting of lever 5 acts through link 13 to move roller 12 to the other side of the fixed pivot 16' of lever 16. Thus when the button 21 is released, lever 16 turns so that roller 15<1> moves on to arm 5a of lever 5. Thus a subsequent depression of button 21 restores the switch to the original position. A modified arrangement for moving the roller 15<1> across is also described. The button 21 may be dispensed with. In this case the lever 18 projects from the casing and is operated directly.

Filed: 1955-01-28
Abstract: 766,756. Washing-machines. ALTORFER BROS., CO: Jan. 28, 1955 ,No. 2691/55. Class 138(2). A washing-machine includes a hollow perforated dasher 16 having a dependent skirt portion 19 spaced an appreciable distance above the bottom of a tub 1, means for moving the dasher in an orbital path to effect a washing action, and means including an upstanding ring 24 inside and eccentrically located relative to the skirt portion 19 for creating an outward pumping action between adjacent portions of the dasher and tube for directing articles of clothing away from the space therebetween. The ring 24 is secured to the bottom of the tub 1 and is preferably of resilient material such as rubber but may be of metal. Circumferential ribs 27 on the ring 24 prevent articles from floating into the space below the dasher when the dasher is at rest. A drive shaft 3 carries a crank pin 7 on which is journalled a head 8 provided with a sleeve portion 9 supported by a ball 10 on the upper end of the crank pin 7. The dasher 16 is secured to a connecting rod 11 extending upwardly from the sleeve portion 9. A flexible boot 12 is clamped at its upper end to the head 8 and at its lower end to a flange 14 on a casting 5. Perforations 20<SP>1</SP> in the body of the dasher produce water jets acting on the clothes as the dasher moves orbitally. The dasher 16 is also provided with radial fins 20 at least some of which have flexible yieldable vanes 21 thereon. The tub 1 is rotated for spin drying by means of a tubular shaft 4.

Title: Improvements in and relating to the cooling of coke and obtaining a nitrogen hydrogen mixture
IPC: C10B39/04
Filed: 1930-01-28
Abstract: A mixture, suitable for ammonia synthesis, containing nitrogen and hydrogen in the ratio of 1 : 3 is produced in a coke-cooling plant by treating the hot coke simultaneously with water and air and passing the gases, without intermediate condensation of steam, to an apparatus in which the carbon monoxide is converted to its equivalent of hydrogen by causing it to undergo a catalytic reaction with steam. The excess steam from the cooling operation serves as part or all of the steam required for the carbon monoxide conversion.  The air is supplied to the coke-cooling chamber at a higher level than the water, the coke temperatures at the two levels being about 900 DEG C. and 550 DEG  C. respectively. Specifications 329,751, [Class 51 (ii), Furnaces and kilns for applying &c.], is referred to.

Title: Production of N-Acyl Ethionimides
Inventor: DISTLER HARRY
IPC: C07D291/06
Filed: 1967-01-19
Abstract: 1,170,683. N-Acyl ethionimides. BADISCHE ANILIN- & SODA-FABRIK A.G. 19 Jan., 1967 [20 Jan., 1966], No. 2875/67. Heading C2. [Also in Divisions Cl and C3] The invention comprises N-acyl ethionimides of the formula where R<SP>1</SP> is hydrogen or an aliphatic hydrocarbon radical and R<SP>2</SP> is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical or the group where R<SP>3</SP> is a phenylene or C 1-10  alkylene radical. The compounds are prepared by reacting a carbyl sulphate of the formula with a nitrile R<SP>4</SP>-CN, where R<SP>4</SP> is hydrogen, or an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical or the group -R<SP>3</SP>-CN. When R<SP>2</SP> is one of the above hydrocarbon radicals it may be substituted by one or more groups which are inert under the reaction conditions, e.g. halogen, nitro and alkoxy groups. It is preferred to effect the reaction at 0-150 C. in the presence of an inert solvent using equimolar amounts of reactants. The carbyl sulphate may be prepared in situ from the appropriate α-olefin and sulphur trioxide. Alkaline hydrolysis of the ethionimides yields an amide R<SP>3</SP>CONH 2  and a salt of a vinyl sulphonic acid. Examples relate to the preparation of acetyl ethionimide, acryloyl ethionimide, benzoyl methyl ethionimide, acetyl octyl ethionimide and adipoyl-bis-ethionimide and the hydrolysis thereof.

Looks, permutation.-A coded locking device for the petrol taps or valves of motor cars and other valves comprises a push-pull actuating tube C which is fitted internally with three spring tongues d each having a bolt E extending through the tube for co-operation with the edges of three coded discs G. To open the tap, the discs G are separately rotated by spindles H until the correct code letters &c. are exhibited at the bevelled apertures L whereupon the spindles H are pulled forward to jam a brake disc M within spring gripping fingers N and set the code; the tube C is then pushed forwards into the enclosing box B, the bolts E each passing through a slot in the edges of the code discs, and the valve A is opened. At the same time a collar P on the tube C contacts a three-armed striker Q which moves along and releases the brake discs M from the gripping springs N whereupon torsion springs R acting on sleeves J attached to the code discs return the code discs to their neutral zero position; thus the code is not exhibited after the valve is opened. In closing the valve the bolts E ride over the edges of the discs G into the locking position.

Abstract: 765,310. Refrigerators. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 8, 1955, No. 3688/55. Class 29 A refrigerator cabinet is divided into an upper freezing chamber 23, including the cooling unit 26, and a lower food storage chamber 24, by a horizontal partition 22, with one edge spaced from the adjacent cabinet wall to form an air passage 42, and so shaped as to direct air cooled by the unit 26 to a portion only of the air passage 42 so that warm air from the food storage chamber 24 may pass up through the remainder of the passage. The partition 22 is spaced from the back wall of the refrigerator, and its base 43 slopes generally in the direction of one of the diagonals, and has upstanding sides one of which is cut away at 46 (Fig. 7) at the bottom of the slope. Cold air dropping from the cooling unit flows down the slope and into the air passage 42 to the food storage chamber 24 through the cut away portion 46. A movable baffle 49 substantially coextensive with air passage 42 is adjustable by a thermostat 52 responsive to the temperature of the food storage chamber. A meat container 28 may be underslung from the partition 22, sliding on projecting flanges of brackets 53, 54. A tray 62 also slides between the brackets and projects across the path of the coid air descending from passage 42. The cold air flows across the tray 62 and is led away through a cut away portion 63 and a slot 64 in thebracket 54. In this way the meat is kept at a lower temperature than the remainder of the food storage chamber. Preferably the descending cool air next surrounds a bottle container 29 so that on reaching the vegetable pans 31 at the bottom of the chamber 24 it is considerably warmer and moister than on leaving the freezer chamber 21.
