Title: Preheating tungsten cathodes in high power electron tubes - prevents overheating when full power is switched on
Inventor: GERLACH PIERRE
IPC: H01J1/13
Filed: 1975-03-04
Abstract: Preheating of tungsten cathodes contg. Th and used for high-power electron tubes comprises maintaining the cathodes continuously at a temp. (I) between their temp. in the cold state and their normal operating temp., where temp. (I) is sufficiently low so that the tube does not require cooling, but is high enough so that the cathodes may be immediately raised to their normal operating temp. With a normal operating temp. of >1600 degrees C, the preheating temp. (I) is pref. 800-1000 degrees C. Used e.g. in transmitter triodes used in radio- and television-transmitters, where the cathodes consists of a cylindrical grid made of tungsten wire contg. 1% ThO2. Prevents the temporary overheating of part of the cathode wires when the high current is switched on due to the low resistance of the cold wire; such overheating leads to deformation of the grid each time the tube is switched on and can lead to the breakdown of the tube.

Title: Off peak electric storage heater - has continuous resistance wire as temperature sensing element in thermal core
Inventor: ANDRE JACQUES
IPC: G05D23/24
Filed: 1975-03-24
Abstract: The heater has a thermal core (1) with air passages (3) through it. The core has electric heater elements (2) connected to an input switch (11) which is operated from a control box (10). A fan (4) circulates air through the core to extract the stored heat during the daytime heating period. A wire (8) runs transversely through the core and has a resistance which is a uniform function of the temperature. It is connected to the control box (10) where its total resistance is measured to give an averaged value of the core temperature. This avoids errors arising from measurement of temperature at a single point in a core different parts of which are at different temperatures.

Title: Constant press. multiple effect evaporator - with infinite number of stages, more efficient than conventional multiple effect evaporators
IPC: B01D3/34
Filed: 1975-05-20
Abstract: An evaporator, having a hot source and a cold source incorporates a heat-exchanger between those sources. The soln. to be evaporated is conveyed, together with a gas, through the exchanger towards the hot source, and the gas, satd. and reheated in the hot source, is recirculated countercurrent to the mixt. of soln. and gas. The mixt. remains under constant press. and its temp. and compsn. vary continuously along the exchanger, maintaining the necessary temp. gradient for heat transfer. The cold source separates humidity from the recycled gas and a blower re-injects it into the soln. to be evaporated, at the entry to the heat exchanger. The evaporator operates in a continuous manner, and the efficiency is greater than that of existing multiple effect evaporators in which the operation is in a number of stages.

Title: Treatment appts. for skins - comprising rotatable parallelepipedal drum with axis passing through opposite corners
IPC: C14C15/00
Filed: 1976-05-11
Abstract: Appts. for the treatment of skins comprises a parallelepipedal drum which can be rotated around a horizontal axis passing through two of its opposite corners. The drum is made from wooden staves connected by metal strips. It is supported by pedestals carrying bearings and is driven by an electric motor. A sliding door covers an opening for entering and removing the skins while a valve serves for evacuating treating liqs. A double bottom, provided with openings, allows liqs. to pass but prevents the valve from becoming blocked by the skins. As the drum rotates, the skins fall into the bath of liq.; at each half-turn they fall in the opposite direction thus preventing them from becoming entangled. Appts. is suitable for cleaning and softening skins, by re-hydrating the fibres, for loosening the hairs of the epidermis or for tanning. As the skins fall in opposite directions as the drum rotates, there is no risk of the skins clinging together and preventing penetration of the treating liqs.
