Title: Liquid cooled semiconductor - particularly applicable to thyristors. coolant temperature is raised by two degrees for 200 watt dissipation
Inventor: PELISSIER PIERRE
IPC: H01L23/473
Filed: 1974-07-05
Abstract: A thyristor group supplying about 100 watts requires a flow of coolant, which is necessarily some electrically insulating oil, of two litres per minute giving a 4 to 5 metres per second flow, the temperature difference between the thyristor surface and the oil being about 20 deg.C. Entry and exit of the oil from such a group of thyristors is via single ports leading to channels in the overall thyristor group casing. A nut ring on a cylindrical body exerts through an elastic washer and an insulating sheet a pressure on a connexion plate. This plate transmits the pressure to the end of a semiconductor element bearing on the base of the body through other connexion plates and semiconductor elements.

Abstract: Bath for the anodic oxidn. of unalloyed or alloyed aluminium, consisting of an aq. soln. contg. chromium with valencies VI and III, also contains 20-100 g/l CrO3 and 0.5-15 g/l chromium chromate (CrO4)3Cr2. The bath pref. contains 20-100 g/l CrO3 and an amt. of (CrO4)3Cr2 between 0.5 g/l and the limit of its solubility at the working temp. of the bath, esp. to obtain 0.076-2.3 g/l CrIII; The pref. process uses a bath with max. temp. 65 degrees C at 5-90 volts, esp. to obtain a translucent coating assuring corrosion protection and also revealing the macrographic structure of the workpiece. Alternatively, the pH may be maintained above 5.5 to obtain only a barrier layer. The bath can be used to obtain a translucent coating which reveals structural defects inthe surface of the Al substrate. Cf conventional baths, which need about 7 days to reach equilibrium between the different Cr ions, this bath can be used immediately.

Title: Cathode ray tube trajectory correction device - applies steady potential to screen and superimposed steady and varying control potential to grid
Inventor: CIECIERSKI JEAN
IPC: H04N9/27
Filed: 1974-11-05
Abstract: A device is used to obtain a correction of the trajectory of the electron beam in a cathode ray tube using a penetrating screen for polychromatic or persistent displays. The tube (1) has an electron gun (2), electron beam (5) and multilayer screen (3). The screen (3) is at a steady potential which defines the penetration of electrons in the screen (3). A grid (4), near the screen (3), is at a varying potential superimposed on a steady potential. The varying potential is related to the angle of deflection of the electron beam (5) by a parabolic law and such that the electron impact point on the screen (3) is almost the same whatever the energy of the electrons. By changing the potential of the screen a change in persistence or colour can be obtained.

Patent FR-2286207-A1 (FR)
IPC: C23F13/02
Filed: 1975-09-03
Abstract: In order to protect a warm-water container (1, 2, 3) and piping and fittings downstream thereof against corrosion, there is provided a combination of sacrificial anodes (A, B, C) and inert anodes (D, E, F, G), fed by direct current, arranged in the container (1, 2, 3). The inert anodes (D, E, F, G) are arranged in the lower part adjacent to the cold-water inlet point (6) and in the central part, pure-aluminium sacrificial anodes (A, B, C) are arranged in the central and in the upper container part adjacent to the warm-water outlet (7). Thus the normal drawback of inert anode systems, the formation of oxyhydrogen, is prevented, as the aluminium of the sacrificial anodes (A, B, C) dissolving anodically binds the oxygen rising from the inert anodes (D, E, F, G). At the same time, such an arrangement extends the useful life of the sacrificial electrodes and reduces the formation of anode sludge on the container bottom as well as the current consumption.

Title: Bolt clamping force measuring device - has slotted washer with deflection of sectors used as measure of force
IPC: G01L1/04
Filed: 1975-09-24
Abstract: A bolt clamping force measuring device is used to determine the load exerted by the bolt. It provides a simple means to ensure that the load is neither too small nor too great. The device consists of a washer which is placed under the head of the bolt. The washer is made of elastic material. It is divided into sectors (1,2). Some of the sectors (1) are plane and the others (2) are curved. The outer diameter (3) of the curved sectors (2) are nearer the centre of the bolt than the outer diameter (4) of the plane sectors (1). When the clamping load is applied, the curved sectors (2) are deformed. The displacement of the outer diameter (3) of the curved sectors (2) is a measure of the clamping load. Washers of various thickness and materials are made to obtain various loads.

Title: Screw head design preventing screw removal - has slot faces transmitting removal torque cut away to form ramps
IPC: F16B23/00
Filed: 1975-12-12
Abstract: The head of the screw is so designed that once in place, the screw cannot be unscrewed. A slot (3) for a screwdriver, is cut in the head in the usual way, but only those sides (3", 3"') which transmit the drive in one direction are left vertical. The other sides on which the screwdriver blade normally bears when unscrewing, are cut away and form ramps (5, 5'). If an attempt is made to unscrew the screw, the screwdriver blade slips, the head forming a rotary ratchet. The system is equally applicable to cruciform indentations. In this case, four of the vertical drive faces are ramped to obtain the same action.
