Abstract: 462,106. Starting oil engines. BOSCH AKT.-GES., R. Aug. 24, 1936, No. 23169. Convention date, Sept. 6, 1935. [Classes 7 (iii) and 7 (v)] A starting carburetter, put into action by movement of a butterfly valve G which cuts off the normal air inlet C, comprises a fuel container J disposed below a well 6 through which projects upwards an open fuel nozzle tube 7 terminating within a tubular extension 3 of a spring-pressed valve 2. The valve controls a contracted portion of a casing K, which houses the valve and a heating coil H above it and is provided below the valve with air inlets. A calibrated passage 41 in a plug 4 at the top of the tubular extension 3 permits air drawn through the member to lift fuel from the nozzle tube 7, and as the suction raises the valve 2 secondary air flows around the tubular member 3 and past the valve 2, the supply of mixture continuing until the container J is emptied. The nozzle tube 7 communicates through a passage 10 with a conduit 15<1> in a rotary valve 11 and the conduit 15<1> opens through a passage 15 into the container J, air being admitted thereto through a conduit 161 and passage 16. On rotation of the valve 11, the passages 10, 15 and 16 are cut off and a passage 17 communicating with the overflow of the oil filter is connected to the container J, which fills to a level determined by an overflow passage simultaneously connected to the return pipe leading to the fuel tank.

Abstract: 1450497 Stackable plates TEDECO VERPACKUNG GmbH 24 May 1974 [25 May 1973] 23218/74 Heading A4A A stackable plate of thin plastics film has a base 1, an annular wall 2 extending from said base and a rim 3 projecting radially outwards from said wall, said rim 3 being bent in a narrow region obliquely downwards and inwards, at 4, and then radially outwards, at 5, forming an approximately Z-shaped cross-section. A narrow annular shoulder 6 is formed on the wall, parallel to the base 1 at the same level as the lower portion of the rim, see Fig. 3, and is connected to the rim by means of a collar 7 which becomes narrower towards the rim, preventing the plates in the stack from jamming. In the embodiments shown, the rim is substantially square, having rounded off corners 3a and straight sides 3b, only these sides being provided with the Z-shaped portions. Parts 3a of the rim periphery include rim portion 8 which is bent obliquely downwards and outwards. The rim is thus provided with at least two support points 10 for tipping the stacked plates. In the embodiment of Fig. 5 (not shown), the radial distance between the wall (2') and the nearest part of the rim portion (4'), which is bent downwards, is smaller than that of the radial rim portion (3').

Title: Improvements in processes for producing metallic sulphides, selenides and tellurides
Inventor: ROTHSCHILD SIEGFRIED
IPC: C01B19/00
Filed: 1954-08-11
Abstract: To produce a metallic sulphide, selenide or telluride, an organic metal compound which is solid at room temperature is purified by repeated crystallization and chromatographic adsorption, and the purified compound is reacted with the non-metallic constituent or a compound thereof.  Lead tetraphenyl is purified by crystallization from benzene and then dissolved in benzene, through which H2Se is bubbled until precipitation of PbSe is complete.  The precipitate is dried with nitrogen containing 5 per cent H2Se.  Lead tetraphenyl purified by crystallization and chromatographic adsorption with activated aluminium oxide is decomposed by heat in an atmosphere of hydrogen, intimately mixed with elemental sulphur in an atmosphere of nitrogen containing 5 per cent H2S.  The product is stored in tubes filled with argon.  The process is particularly suited to heavy metals and to zinc.

Abstract: 748,834. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 28, 1953 [Aug. 28, 1952], No. 23871/53. Class 39 (1). [Also in Groups XL (b) and XL (c)] An electroluminescent display system comprises two arrays of electrically conductive individual elements one array arranged at an angle to the other and separated from it by a phosphor layer, the two arrays being energized at different periodicities for line and frame scanning with or without interlacing. The energizations operate near the light threshold region of the phosphor. The subject matter is substantially the same as that described in Specification 746,502 with the exception of Fig. 6 which shows a radar display in polar co-ordinates. The driving motor 105 for the radar antenna also drives the movable contact of a commutator 108 the fixed contacts of which are connected to the radial display elements 113. The keying unit 102 is connected across a delay line 109 successive taps of which connect to the concentric display elements 111 giving repeated and successive energization of these elements. The pulse modulation component at the receiver 103 is also applied to the delay line 109. Between the radial and concentric elements lies the electroluminescent layer. The reflected radar pulse at the receiver produces an output signal which is applied through battery 114 to the commutator 108 and thereby to the radial elements of the display. Specifications 731,345 and 735,752 also are referred to.
