Abstract: 681,784. Radio refractors. WESTERN ELECTRIC CO., Inc. Dec. 20, 1950 [Dec. 23, 1949], No. 31022/50. Class 40 (vii). A lens for refracting radio waves of the type comprising a plurality of dielectric channels as described in Specification 650,767 comprises two sections, one converging and the other diverging, so proportioned as to result in an " achromatic " combination, i.e. a lens having wide-band properties. The arrangement illustrated comprises a cylindrical lens with the mouth of a sectoral horn 4 placed at its focal line. The lens comprises a plurality of equallyspaced identical plates 9 which are so shaped that the lens may be regarded as consisting of two portions, viz.: a rear stepped concavoconcave positive portion and a forward unstepped plano-convex negative portion, Fig. 2. By virtue of the stepping, the power of the positive lens, for a given band-width, is greater than that of the negative lens, so that by designing the two portions of the lens to have equal band widths (which, however, produce oppositely directed phase distortions of the output wave front) the resultant combination has characteristics substantially independent of frequency.

Abstract: 414,636. Facilitating changing speed. CHRYSLER CORPORATION, Highland Park, Michigan, U.S.A.-(Assignees of Neracher, C. A. ; 225, Covington Drive, Detroit, Michigan, U.S.A.) Nov. 4, 1932, No. 31199. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 5, 1933]. [Class 80 (ii).] The main or other clutch of a motor vehicle is automatically disconnected by means responsive to engine speed when the engine is running slowly, and a one-way clutch is provided between the variable gear and the final driven shaft. The automatic clutch-disengaging means may be put out of action and the one-way clutch locked by a single control member when desired. In the construction shown in Fig. 1, a cylinder 4 for disengaging the clutch is adapted to be connected to the engine induction pipe 2 through a pipe 13 and valve 1 having two plungers 9, 10, 9 being connected to the accelerator pedal and 10 to a hand-operated shaft 25. In the position shown, the accelerator pedal having been released to cause the engine to run slowly, the cylinder 4 is connected to the pipe 2 through annular passages 15, 17 in the plungers, and the clutch is withdrawn by the piston 3 acting through a lever 6. When the accelerator pedal is depressed to accelerate the engine, the plunger 9 is moved to the right, the pipe 13 is cut off from the induction pipe and is connected to the atmosphere by a groove 16 in the plunger 9, and the clutch is re-engaged. The rate of engagement of the clutch is controlled by a pipe 21 connecting the front end of cylinder 4 to a bore 20 in the valve 1 co-operating with a bleed groove 19 in the plunger 9. If the plunger 10 is moved to the right by the driver, the cylinder 4 is connected to the atmosphere by a groove 18 in the plunger so that the clutch can only be disengaged by the usual pedal. The one-way clutch comprises friction rollers 30, Figs. 2 and 4, spaced between a cam member 28 on the gear shaft 26 and an outer member 29 fixed on the propeller shaft 27, so that shaft 27 can over-run shaft 26. The clutch can be locked by means of a sliding gear 34 splined on shaft 26 and adapted to engage internal teeth 33 on the member 29. The locking gear is normally held inactive by a spring-loaded sliding bar carried in the gearbox. When the shaft 25 is operated by the driver to put the clutch-disengaging cylinder 4 out of action a Bowden wire 22<a> is also actuated and moves the sliding bar and gear 34 to look the one-way clutch. The clutch is also locked by the ordinary reverse gear.

Abstract: 718,860. Refrigerating. GENERAL MOTORS CORPORATION. Dec. 10, 1952 [Feb. 23, 1952], No. 31232/52., Class 29 A household refrigerator comprises a freezer compartment 12 and a storage compartment 14 cooled by evaporators 26, 28 respectively, connected in series, a secondary system the condenser 52 of which is in heat-exchange relation with the evaporator 28 and the evaporator 50 of which 'is in heat-exchange with the  lower part of compartment 14 to cool crisper pans 44, a thermal element 60 responsive to the temperature of evaporator 28 for stopping the compressor motor 18 at a temperature below 32‹F and starting the motor at such a temperature as will permit defrosting of the evaporator 28 during the idle period, and a heater such as an electric lamp 63 for artificially supplying heat to the compartment 14 at low ambient temperatures to ensure sufficient operation of the compressor to supply adequate freezing in the compartment 12. Refrigerant passes from receiver 22 through a restrictor tube 24 led through the compartment 14 in heatexchange therewith to the inlet of the freezer evaporator 26 encircling the compartment 12. The final part 30 of evaporator 26 upwardly slopes in the manner shown on the back wall of compartment 12 and is of oval section the longer axis of which is vertical so that gas and liquid can pass therein without the gas carrying slugs of liquid out of the evaporator. When the demand for refrigeration in compartment 12 is satisfied, liquid refrigerant spills over from pipe 30 and runs into evaporator 28 which is of low thermal mass and comprises a vertical plate having in series a peripheral evaporator passage 34, an accumulator 36, a central evaporator passage 38, an accumulator 40 and an outlet passage 42 leading to the compressor and in heatexchange with the restrictor 24. The passages of the evaporator 28 are flooded to a greater or less extent depending on the degree of cooling required and they are so arranged that, when the compressor stops, the rise in pressure will force any liquid in the passage back into the evaporator 26. When the compressor is stopped by thermal element 60, evaporator 28 defrosts, this being accelerated by heat conveyed thereto by the secondary condenser 52. Defrost water is caught in a tray 70 and is led by a pipe 72 to a tray 74 in the machinery compartment for evaporation by the heat generated. therein. The heater 63 is controlled by a thermostat 64 located in the machinery compartment so that at low ambient temperatures, the heater is energized, an intermittent heating, the frequency of which is greater the lower the ambient temperature, being produced by an electric heater 66 in series with and adjacent to the thermostat 64. For viewing the refrigerator interior, the lamp 63 is also controlled by a door switch 68. Specifications 694,293 and 716,651 are referred to.
Patent GB-312348-A (GB)
IPC: C10B57/18
Abstract: 312,348. Pott, A. May 25, 1928, [Convention date]. Gaseous mixtures. - The calorific value and density of coal distillation gases are regulated by the addition of a diluting gas prepared by the interaction of coal gas with steam or air or both at high temperatures, e.g. 1100-1200‹ C. The diluting gas is variable within wide limits from a high to a low density by employing air alone, mixtures of air and steam or steam alone in the reaction. A constant or automatically adjustable quantity is branched off from the distillation gas supply and converted into diluting gas which is then united with the distillation gas. The amount of gas to be added and the regulation of its calorific value and density may be controlled automatically in dependence on the corresponding values of the distillation gas which are obtained by continuous or periodical measurement and caused to control mechanically or electrically the regulating means. In examples coal gas of specified composition is treated respectively with steam, air and steam, and air at 900-1100‹ C., 800‹ C., and 800‹ C. or more to produce diluting gas mixtures consisting of carbon dioxide, carbon monoxide, hydrogen and nitrogen, in which the hydrogen content is 75, 55, 49 per cent and the nitrogen content is 6, 27, 34 per cent respectively, specified proportions of each mixture being added to the coal gas to provide three mixtures with a single prescribed calorific value and varying densities.

Filed: 1918-09-27
Abstract: 136,833. Soc. Industrielle de Produits Chimiques. Ma.y 27, 1918, [Convention date]. Ammonia; ammonium sulphate; sodium sulphate.-Ammonia is recovered from coke-oven and like gases by absorption in a solution of sodium bisulphate at 70‹ C., so as to produce a precipitate of sodium-ammonium sulphate. The precipitated meed is heated with agitation at 111‹ C., and over half of the contained sodium sulphate is precipitated in the anhydrous form, which is separated in a pressure filter at 110‹ C., and is purified by recrystallization. The filtrate is cooled to, say, 70‹ C., and ammonium sulphate separates and is washed. By suitably choosing the quantity of water used for dissolving the sodium bisulphate, the quantities of sodium and ammonium sulphates obtained may be equivalent to one another, and the mother-liquor may be used again with more bisulphate. Specification 19530/93 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the sodium-ammonium sulphate may be dried and heated to 350-600‹ C. to obtain ammonia and sodium bisulphate, which is used again.
