Abstract: 344,337. Solar ray demonstration apparatus. COOKE, TROUGHTON & SIMMS, Ltd., Buckingham Works, York, and CLAY, A. S., 16, St. James' Square, London. Sept. 3, 1929, No. 26798. [Class 106 (i).] An instrument for use on architects' plans to demonstrate the angle of the sun's rays at any hour of the day comprises a base, an hour circle representing the plane of the sun's path, and a pivotal member attached to the base and adapted to represent the sun's direction. In the form shown in Figs. 1 and 2 the semicircular arc B graduated in hours from sunrise to sunset is disposed upon a baseplate A at an angle dependent upon the latitude of the locality. At a point C<x> representing the observer's position is secured a cord C to the other end of which is attached a ball C<1> denoting the sun. The point C<x> is selected so that the cord when set at noon makes an angle with the plane of the arc equal to the mean declination of the sun for the summer months. A similar but differently angled instrument may be used for the winter period. In a modification shown in Figs. 7 and 8 the arc B is a portion of a spherical surface and is graduated at both its edges for summer and winter use. In a further construction, Fig. 11, the arc is replaced by a graduated ring rotatably mounted in a horizontal annular plate A. The ring is graduated along both edges and may be variably set for latitude, both north and south.

Abstract: 276,860. McKinlay, D. Oct. 27, 1926. Cocoa preparations.-Chocolate confectionery is treated after manufacture with ultra-violet rays from a quartz mercury vapour lamp to increase the vitamine content to an amount corresponding to or in excess of that of the original ingredients in a raw state. In one form, chocolates 31 preferably unwrapped are carried on trays 32 by an endless band conveyer 9 under a quartz mercury vapour lamp 29. The treated trays are removed on a conveyer 11. The conveyer 9 is carried by chains engaging with sprocket wheels 6, 7, the wheel 7 being, intermittently driven through suitable gear from a continuously rotating shaft 12 so that the conveyer pauses when a tray is directly under the lamp 29. Shaft 12 has an eccentric 13 which engages with one end of a, pivoted lever 14 causing it to oscillate and oscillate through toothed sectors 16, 20 a pivoted lever 19. A pawl 21 on lever 19 engages and rotates a ratchet wheal 18 which rotates a sprocket wheel 22 driving sprocket wheel 7 through a sprocket wheel mounted on its shaft 5, and a chain 23. The effective throw of pawl 21 can be varied, so as to alter the movement of the convever according to the size of the trays used, by a shroud 24 formed as a pivoted sector 25. The sector can be adjusted through a rod 26 and a lever 27 moving on a graduated quadrant 28 so that the pawl in its return movement rides thereon for a greater or less distance. In other forms, the trays carrying the confectionery are removed by a rotary drum, or the lamp or lamps are moved over the confectionery which is laid out on tables, frames, conveyers, &c. The distance of the confectionery from the lamp and the duration of exposure is varied according to kind of the confectionery and the result desired. Specification 236,197, [Class 49, Food &c.], is referred to.

Title: Control device for gas turbine aircraft propulsion units
IPC: F02K3/00
Filed: 1950-11-07
Abstract: 711, 846. Gas turbine jet propulsion plant. SOC. RATEAU, and ANXIONNAZ, R. Nov. 7, 1950 [Jan. 26, 1950], No. 27212/50. Class 110(3) A control device for an aircraft gas turbine propulsion unit having an air compressor, comprises a governor responsive to the rotational speed of the unit and detecting means responsive to the air temperature or pressure at the inlet of the compressor which are connected through conjugate transmission means to means for adjusting the velocity of flow through the unit. The flow adjusting means described are the fuel supply and a variable area propulsion jet. The purpose is to prevent a given Mach. No. in the unit being exceeded. In the jet propulsion plant shown the fuel supply to the combustion chamber 3 is controlled by a by-pass valve 18 which is actuated by a rocking lever 16. The lever 16 is connected, at the end opposite to the valve 18, to a spring 15 the loading of which is determined by the setting of a pilot's lever 14 and a servomotor 11. The servomotor is operated by a bimetallic strip 7 located in the air intake to the compressor 2 so that an increase in temperature of the inlet air increases the loading of the spring. A speed governor 17 driven by the gas turbine is connected to an intermediate point of the lever 16 so that the loading of the governor balances that of the spring 15. For each position of the lever 14 there is. therefore, a rotational speed of the turbine corresponding to each valve of the inlet temperature. In a modification, the bi-metallic strip 7 is replaced by a barometric device responsive to the ram pressure. In another modification, the bimetallic strip 7 and speed governor 17 are used to control a variable area jet propulsion nozzle. It is stated that both the fuel supply and the area of the jet propulsion nozzle may be operated simultaneously. The invention is also shown applied to ducted fan and propeller turbine engines. Specifications 650,661 and 650,710 are referred to.
