IPC: B61C17/02
Filed: 1926-04-26
Abstract: 252,142. Goldschmid, G., and Weber, A. May 13, 1925, [Convention date]. Automatic power control. - Relates to an articulated locomotive carried on two driving bogie trucks, one of which carries a water tank, and comprises controlling means whereby as the weight on the rear bogie is reduced owing to the consumption of the water and fuel supported thereby, the power exerted by this bogie is reduced automatically by means of a float in the water tank acting on the reversing gear. The float i, Fig. 4, rotates a screw-shaft k, Fig. 6, and so opens or closes a valve m controlling the supply of pressure fluid from a pipe n through a pipe o to a spring-biassed piston w. This piston and its cylinder are carried by the reversing lever q. The reversing gear for the rear bogie is connected by a rod r to the,piston w so that when the float falls and the supply of fluid to the piston w is cut off, the piston rises and the reversing gear is shifted to reduce the power. The reversing gear for the forward bogie is directly connected by a rod s to the reversing lever.

Title: A signal storage tube
IPC: H01J31/60
Filed: 1959-04-03
Abstract: 892,431. Cathode-ray storage tubes. TELEFUNKEN G.m.b.H. April 3, 1959 [April 3, 1958], No. 11413/59. Class 39(1) In a cathode-ray storage tube a constant intensity writing beam of rectangular crosssection, the axes of the rectangle being at least in the ratio of 1:5, is swept along a stripshaped storage electrode extending transversely of the major axis of the rectangular cross-section and at the same time is deflected transversely of the storage electrode in dependence on the signal to be stored. The same beam or a similar beam is used for reading. In the embodiment shown in Fig. 1, the beam 1 is scanned in the direction of the arrow across a target consisting of two strip storage electrodes 3 and 4 and a pick-up plate 5 and is deflected transversely across the target by deflecting plates 2 to which the signal is applied resulting in a stored charge pattern as shown. The same beam or a beam from a second gun is again scanned over the target in the reading part of the cycle and may read the charge on either electrode 3 or 4 resulting in an output signal at the load resistor 6. The electrode 3 or 4 which is not scanned by the reading beam need not have a storage effect. A pick-up electrode may be associated with each electrode 3 and 4 and both may be read out simultaneously by a reading beam extended over both paths. In the embodiment shown in Fig. 2 the beam emerges as a beam with a circular cross-section from the gun and focusing system 11-15, and is then scanned in a conical path through lenses 16-18 which stretch the beam in a radial direction so that it impinges on the targets 22, 23 with a substantially rectangular cross-section. The deflecting input signal is applied to the plates 19, 20. The plates 19, 20 may be composed of partial plates to improve the deflection sensitivity and may be formed by sections consisting of concentric truncated cones or truncated hyperboloids placed one behind the other, the deflection being accomplished by applying differing voltages to the individual sections.

Filed: 1927-05-02
Abstract: 300,142. British Celanese, Ltd., Bader, W., and Green, S. J. May 2, 1927. Methanol. - Catalysts for the synthesis of methanol are prepared by precipitating zinc carbonate in a gelatinous form, washing and drying the product in such a manner as to retain the colloidal state, and heating the gel at a temperature not exceeding that to be employed in the methanol synthesis. The zinc carbonate gel may be produced by precipitation in very dilute solution, or by incorporation during or after precipitation with a protective colloid such as starch, pectin, saponin, or hydrated silica. The washing of the zinc carbonate gel is effected by decantation to remove all traces of electrolyte, and the drying may take place under reduced pressure. For the final heating to produce the zinc oxide catalyst, temperatures of 250‹-450‹ C. are employed; this conversion may be effected either before or during the methanol synthesis. The zinc oxide catalyst may be used in conjunction with a promoter such as chromium oxide, or with another methanol catalyst or mounted upon a carrier, provided that the gel structure of the intermediate zinc carbonateis retained. An example is given of the preparation of a catalyst by precipitating a dilute solution of zinc nitrate with a dilute solution of sodium carbonate, mixing the washed precipitate with starch jelly, and employing the product, in a dried and broken state, directly for the synthesis of methanol under a pressure of 80-120 atmospheres.
