Title: A process for the manufacture of rectifiers
IPC: H01L29/24
Filed: 1931-10-19
Abstract: 373,914. Static contact rectifiers. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 19, 1931, No. 29025. Convention date, Oct. 17, 1930. [Class 37.] A metal base 1, such as copper, has formed upon it an oxide or other coating such as cuprous oxide, the operative portion 3 of which is reduced in area by mechanically removing the outer ring 2 thereof, for example by turning, milling, or with emery, or by separating this part from the central part 2 by cutting a slot 4 through the coating and into the metal. Upon the part 3 of the coating is secured, by means of a screw 5 and nut 6, a lead electrode 7, preferably with the interposition of a layer of graphite. It is stated that the capacity of the rectifier is considerably reduced without much increase in the resistance, thus permitting its use for alternating currents of higher frequency.

Title: Improvements in or relating to electron beam-generating systems for electric discharge tubes
IPC: H01J3/02
Filed: 1966-06-29
Abstract: 1,103,890. Discharge apparatus. SIEMENS A.G. 29 June, 1966 [30 June, 1965], No. 29162/66. Heading H1D. In an electron beam generating system, e.g. for a travelling wave tube, comprising a main dispenser cathode having at one end a porous emitter substance carrier disc 2 which forms the closure of a shallow cylindrical dispenser vessel 3, the main dispenser cathode is heated by the impact of electrons on the bottom of vessel 3 in an auxiliary discharge which is coaxial with the main beam and is formed between an auxiliary indirectly heated dispenser cathode 8 and the bottom of vessel 3 and has an associated Wehnelt cylinder control electrode 10, the voltage on which controls the main beam cathode temperature. An anode 5 is disposed coaxially within main beam-forming electrode 1 to accelerate the electrons and has one or more coaxial apertured diaphragms 6, 7 one of which, e.g. 7, may be coated with a getter material to act as a getter pump for residual gases. This diaphragm 7 has a smaller aperture than that of entry diaphragm 6 to ensure that, by electron bombardment, the getter is raised to an operable temperature and diaphragm 7 may gradually decrease in thickness towards the rim. The main dispenser cathode may be supported by a tantalum, foil cylinder 4 secured to cathode body 3, which may be of molybdenum, and the junction of support 4 and body 3 may form a thermoelectric junction. The thermo e.m.f. produced, which is related to the main cathode temperature, may be fed into a temperatureregulating arrangement which controls the voltage on the Wehnelt cylinder to maintain the main cathode emission temperature at a predetermined value. An additional foil cylinder 11 may be provided to increase thermal shielding.

The valve 5 comprises a casing 10, Fig. 2, with opposed ports connected as shown in Fig. 1, and a rotatable valve plug 11 which can be set in any one of three positions. In the spraying position, Fig. 2, liquid flows in the direction of the full line arrows, whereas in the position shown in Fig. 3 the liquid in the booms and in the conduits leading thereto is nicked back through the control valve, and flows in the direction of the dotted line arrows through the pump, filter and valve and back to the tank. In the third position the valve ports connecting the tank and booms are blocked. A relief valve 4 and a pressure gauge 9 are provided. Alternatively, the valve ports are not symmetrically spaced, and the valve plug has spraying and suction positions only.

Title: Improvements in hydraulically operated indexing-mechanism for metal cutting and other machine tools
IPC: B23Q16/06
Filed: 1928-10-17
Abstract: 318,414. National Automatic Tool Co., and Sudhoff, A. G. Oct. 17, 1928. Indexing.-In a machine-tool having an indexable work or tool carrying table, the indexing movements are effected by means of a gear which is oscillated by hydraulically-operated racks and the table is held by the hydraulic pressure in its various working positions. The table 12 has an annular bearing 14 on the frame 10 and is carried on a spindle 11 having a bearing 21 in the lower part of the frame. An upper clutch member 23 is keyed to the spindle 11 and is mounted in a bearing sleeve 25. The coacting lower clutch member 28 is slidably keyed to an oscillating gear 26 and the clutch teeth, which are of ratchet form to give a one-way drive are normally held in engagement by springs 32. The table carries stop members 37 secured by screws 39 and having flattened surfaces which coact with a flat on a spring plunger 41. The gear 26 is oscillated by racks 60, 61 which are alternately moved by hydraulic cylinders 56, 57 and one of the racks is adapted to engage a projection 49 on a bell crank lever 47, 48, to withdraw the plunger 41 at the required times. The hydraulic cylinders are supplied from a pump 66 which draws fluid from a sump 67 and delivers continuously through a pipe 70 to the cylinder 57. A further delivery pipe 71 may be connected through a valve 72 and a pipe 73 to the larger cylinder 56. In operation, when the valve is in the position shown in Fig. 5, fluid is admitted to both cylinders and the greater force exerted by the larger cylinder rotates the gear 26 in a direction to cause the table indexing movement and to hold one of the stops 37 firmly against the plunger 41. When the operation in this position is completed the valve 72 is shifted either automatically or, as shown, by means of a handle 83<1> connected to an arm 83 having a projection engaging between collars on the valve rod. A quick throw-over device consisting of a spring plunger 86 coacting with a roller is provided. This causes the cylinder 56 to be opened to exhaust while the cylinder 57 acts to return the gear 26, the clutch 28 ratcheting idly in this direction. Near the end of this movement the rack member 61 engages the pin 49 to withdraw the plunger and then acts on a pin 84 connected by an arm 82 to the lever 83, thus shifting the valve to the position shown in Fig. 5 to effect another indexing movement. Oilways are provided at 88, 89, and from the latter oil flows to a basin 90 and thence through passages 91, 92 to the table spindle bearings. In a modification, compressed air may be used in place of oil for the motive fluid and in a further modification, Fig. 7, the cylinders may be hydraulically supplied from reservoirs 91, 92 while compressed air delivered from a pump 95 and controlled by the valve 72 is selectively admitted to the reservoirs above the oil levels 93, 94.

Abstract: 669,642. Thermal switches. HOLLISTER, F. L. Nov. 21, 1949. [Nov. 20, 1948] No. 30211/48. Class 38 (v). In thermal or other switches with magnetically controlled contacts, one of which is resiliently mounted so as to be movable towards or away from the other, the one contact carries a permanent bar magnet of highly magnetic alloy arranged with its axis parallel to the direction of relative movement and adapted to co-operate with an armature carried by the other contact. In the form shown, the magnet 20 is carried by a fixed member 19 on which is mounted a spring 22 carrying a square iron frame 25 surrounding the magnet and carrying the movable contact 26 which engages the fixed contact 27. The upper and lower sides of the square 25 constitute armatures for the two poles of the magnet and in all positions the lower gap between armature and magnet is less than the upper gap so that the resultant magnetic force on the contact 26 is always upwards. The switch is opened by rise of temperature causing the tube 37 to expand relatively to the rod 35 so that a screw 34 carried. by the rod presses down a lever 31 bearing on the spring 22 which flexes till the contacts suddenly separate. The tube and rod may be replaced by a Bourdon tube or diaphragm and the magnet and armatures may take other forms, Figs. 4-7' (not shown). Reference has been directed by the Comptroller to Specification 625,492.
