A., The Sheiling, Kingsway, Petts-Wood, Kent. May 11, 1934, No. 14235. [Class 40 (iv)] In a hand-combination set, a press-lever 16 in the handle rocks within the handle without any pivot spindle and operates contact springs 33, 34 in the microphone receptacle. The only parts within the handle are the press-lever and the two conductors 4, 5, extending between terminals in the receiver receptacle 2, and in the microphone receptacle 3. The various terminals and supports are moulded in position in the microphone receptacle. As shown, the handle 1 is moulded integrally with the receiver receptacle 2, and the microphone receptacle 3. The lever 16 is retained between a stop 15 and a recess 12 in the receptacle 3 by the strip 351 clamped to the contact spring 34. The lever turns about the fulcrum 19 so that its end 18 moving upwards engages the spring 34 and forces it into contact with the spring 33. In a modification, Fig. 7 (not shown), the fulcrum 19 is further from the receptacle 3 and the spring 34 is curved so that the contacts are closed by downward movement of the end 18. The switch may be used with a three-cord or a four-cord conductor, or for controlling apparatus outside the hand-combination set in wireless telephony.

Title: Improvements in or relating to internal combustion engines of the compression ignition type
IPC: F02N99/00
Filed: 1928-05-18
Abstract: 317,524. Ricardo, H. R. May 18, 1928. Starting.-In an engine of the compression ignition type having means for controlling the quantity of air drawn through an air inlet passage and means for supplying a fuel and air mixture during the suction period for starting purposes, this mixture is ignited by the heat of compression and can only be delivered to the engine when the air inlet passage is reduced or closed. As shown, the air inlet passage D is controlled by a throttle valve E, and a nozzle F for starting-fuel opens into the passage D near the edge of the throttle valve, so that starting-fuel is taken up by the air only when the valve is nearly closed. The fuel is drawn from a small reservoir H through a pipe J having a restricted opening J<1> at the lower end and a larger opening J<2> in its wall, so that a larger quantity of fuel is drawn in at first than subsequently. The starting-fuel has a low self-ignition temperature and may be ethyl ether, amyl nitrite, or amyl nitrate, alone or mixed with other fuel oil. The normal fuel supply to the sprayer B<2> is cut off at starting by a lever B<3> controlling a. wedge C acting on the bye-pass of the fuel pump B.
Patent GB-146884-A (GB)
Abstract: 146,884. Trinks, F. Oct. 25, 1913, [Convention date]. Multiplying and dividing apparatus; zeroizing-mechanism. - In machines of the camdisk and pin-wheel type a number may be directly set on the numeral drums 2 of the totalizing-counter so as to be visible at the reading apertures 11 by operating the knobs 9 of toothed sectors 5 loose on the common shaft 10, such sectors being also adapted to zeroize the totalizing-counter on rotating the handle 20, for which purpose each numeral drum 2 is formed in one with the ordinary actuation-receiving pinion 4 and with a mutilated wheel 7 having a gap 6. The sectors 5 gear with the mutilated wheels 7, and in order to set a number on the counter it is necessary first to displace the drums from zero position, which may conveniently be done by adding one negative unit to the totalizing counter, bringing all drums to " 9." The knobs 9 are then raised as required. All the sectors are mounted on a shaft 10 carried by links 12 from a shaft 15, the links being pressed by springs 14 against a stop 19, so that when a particular setting has been made as above, and it is desired to make further calculations, the sectors may be thrown out of gear by rocking the shaft 15 together with the links 12 against the springs 14. Thereupon they fall to the lowest position, leaving the totalizing-counter drums free from engagement therewith. To zeorize the counter, the handle 20 is rotated to cause a bail 21 moving with the shaft 10 to press upon the edges of the sectors and thus raise them to the highest position.

Filed: 1928-05-19
Abstract: 317,772. Guy, H. L., and Associated Electrical Industries, Ltd. May 19, 1928. Bulk evaporators.-In a bulk evaporator of the horizontal tube type, straight heating tubes of substantially elliptical cross-section are disposed in vertical banks with their major axes in vertical alignment, so that equal vertical passages are provided throughout the whole of the liquid space; priming is thereby reduced as compared with an evaporator of equal heating surface but with tubes of circular section. In a cylindrical shell 1, vertical banks of elliptical section tubes 11 are arranged to leave passages 12, which are wider than those formed by similarly spaced circular section tubes of equal heating area; in the lower part of the evaporator' where priming is least probable, tubes may be arranged with their major axes horizontal as at 13. Above the normal liquid surface A a hot grid to vaporize spray is formed by closely spaced tubes 22 having their major axes horizontal. The tubes in the upper part of the tube banks may be of smaller section or fewer in number than those in the lower part. In place of straight tubes, U-shaped tubes having substantially straight side portions may be used. The elliptically section tubes are preferably made by deforming the central part of circularly sectioned tubes, the deformed portion being eccentric to the original section which is preserved at the ends to facilitate fixing by bushes 19 and gland members 20 in tube plates 2<1>, 3'. Specification 139,177, [Class 64 (iii), Surface apparatus &c.], is referred to.

Title: Catalysts
IPC: B01J23/40
Filed: 1944-08-02
Abstract: A supported platinum metal catalyst is prepared by coating a porous support with a solution containing a metal of the platinum group in an organic solvent having a boiling point of 250 DEG  C. or more at atmospheric pressure and heating the coated support to remove the solvent and deposit the platinum metal on the surface of the support. Preferably the organic solvent is subject to decomposition before its boiling point is reached and may be an oil or fat, e.g., Balsam oil, fish oil, pine oil, and lanoline. The porous support may consist of water soluble material, e.g., magnesium sulphate; reference is also made to the use of aluminium oxide and silica gel.  The coating solution may be in the form of a suspension or an emulsion, and may contain platinum chloride or chloroplatinic acid.  A mixed coating of platinum and palladium may be formed.  The catalyst may be used for oxidation and reduction reactions and is especially useful for the oxidation of sulphur dioxide to sulphur trioxide in the contact process.ALSO:A platinum metal is deposited on a porous support by coating with a solution containing the platinum metal in an organic solvent having a boiling point of 250 DEG  C. or more at atmospheric pressure, and heating the coated support.
