Title: Silicon solar cells mfr. - using thin polycrystalline silicon on flexible substrates
Inventor: FANG PAO-HSIEN
IPC: H01L31/06
Filed: 1976-03-01
Abstract: Method of forming Si solar cells supported on metal esp. Al substrates comprises growing a thin film (is approx. 10 mu) of polycrystalline Si one the Al substrate, of a specific type of impurity and impurity concn. using the Al as nucleation surface for growth of the crystals and doping the Si, followed by forming pn-unctions, to allow the transformation of photovoltaic energy, and forming electrodes and removal leads for electricity produced. The substrate or the terminal leads can contain Ti which getters impurities. Use of a polycrystalline Si layer reduces the costs of prepn. The thickness used is very much less (some 30 times less) than for single crystal Si solar cells. Hence the cost of the Si is reduced proportionately.

Patent FR-2360819-A1 (FR)
IPC: F16M7/00
Filed: 1977-08-01
Abstract: Components of a power station are supported via connecting rods on a support beam (2) and/or the foundations. In order to relieve the components from possible sudden overloading, the support of the connecting rods (1) on the support beam (2) contains rupture members (6), lying parallel to which, with clearance (10), are damping elements (11) made of plastically deformable material, which elements take over the support only in the case of breaking of the rupture members (6) and the resulting bridging of the clearance (10). The material deformation of the damping elements (11) then limits the stress level. Tension bolts with intended breakage points (7) can be used as rupture members (6). A support device of this type serves above all for supporting the main coolant pumps or steam generators of a nuclear power station.

Title: Furnace heating element esp. for coated particle nuclear fuel prodn. - has electrical contact to external bus=bar maintained by tensioned bolts
IPC: H05B3/06
Filed: 1977-09-07
Abstract: An arrangement for obtaining an electrical contact between an electrical heating element inside a furnace and a current supply bar outside the furnace consists of electrode mounted in the furnace wall and comprising a number of electrical connecting elements which connect it to the bus-bar. An internal conducting surface of the electrode acts as the conducting contact face with the heating elements, a bore passes radially (relative to the furnace) through the electrode and houses, as a loose fit, a bolt locked at its inner end into the heating element inside the furnace and equipped at its outer end with an adjustable spring loading assembly which applies an adjustable stress to the bolt so that the heating element is always pulled tightly against the contact surface on the inner face of the electrode. Used in particular for furnaces used for the prodn. of coated particle nuclear fuel, where the fissile material is coated with a pyrolytic carbon or metallic carbide. Such furnaces are subjected to appreciable temp. cycling and operate for long periods, with the result that there is a tendency for the electrical contacts to become loosened. The adjustable pre-stressing action applicable by the spring-loaded device to the bolts retaining the heating elements enables a permanent contact to be maintained at the face for very long periods without the need for access to the interior of the furnace.
