Title: Protection cct for DC voltage regulators with Darlington pair cut-out - has two diodes connected to protect Darlington pair
IPC: G05F1/569
Filed: 1974-02-28
Abstract: The circuit protects the Darlington pair and the control transistor, and has a first diode (D1) connecting the (D) output emitter of the pair to its input base, and a second diode (D2) is connected between the base of the pair and the collector of the transistor (T2) that switches off the pair when a high voltage appears at the output (UA). The first diode protects the input transistor (T1') from UBE-breakdown, and the second diode protects the control transistor (T2). Because of the slow response of a Darlington pair in this circuit, in the absence of the first diode the voltage could rise sufficiently before switch-off to damage the input transistor of the pair.

Title: Self-lubricating combination of coatings - comprising titanium carbide on one element and amorphous carbon on the other, effective under extreme conditions
Inventor: MAILLAT MICHEL
IPC: C23C30/00
Filed: 1990-10-04
Abstract: Self-lubricating combination of coatings on, resp. first and second elements in sliding contact, partic. in a severe environment, comprises on the first element, a layer of titanium carbide (TiC) and on the second a layer of amorphous carbon. Opt. the combination is used in conjunction with at least one of the solid lubricants MoS2, PTFE, lead and silver. The second coating is amorphous carbon contg. hydrogen; amorphous diamond-like carbon or an ion-assisted deposited carbon coating. The TiC coating (on a ceramic or metallic element) is produced by CVD. This same method (or PVD) is used to deposit the amorphous carbon coating. Typically the TiC layer is 1-5 microns thick and the carbon layer 0.1-5 microns. USE/ADVANTAGE - Useful where moving pts. are exposed to vacuum; dry or moist gas; or extremes of temp., pressure and corrosion. These coatings ensure a low coefft. of friction and reduced wear on the coated elements. In an example, a tribometer had a 6 mm dia. bead, coated with TiC, moving on a disc coated with amorphous carbon. A force of 5N was applied and the sliding speed was 10 cm/s. Under an atmos. of 10 power 5 Pa and humidity over 98%, the mean coefft. of friction (after running in) was 0.07 and the wear rate 0.1 x 10 power -15 cu.m./Nm. Under the same pressure but with below 2% humidity the corresponding figures where 0.22 and 0.07 x 10 power -15. When only 1 element was coated (the other bare steel) comparable figures were (a) at high humidity, 0.15-0.23 and 1.2-22 x 10 power -15 and (b) at low humidity, 0.29-0.83 and 1.7-4.6 x 10 power -15.

Title: Composition for labelling with Tc-99m, process for its preparation, agent for producing an optical image and process for preparing the agent
Inventor: SAKLAD EUGENE L
IPC: A61K51/12
Filed: 1979-04-19
Abstract: Compositions which are employed for labelling with Tc-99m and are then used for producing an optical representation utilising radioactivity contain microaggregates of albumin, preferably human albumin, and a metallic reducing agent, in particular a tin(II) reducing agent. These agents can, where appropriate, be in freeze-dried form so that they can be labelled at the place of use immediately before they are used simply by adding a technetium-99m-containing material, for example a corresponding pertechnate solution. The labelled products are an excellent means for visualisation of the reticuloendothelial system (RES), and in particular of the liver, of the spleen and of the bone marrow. Processes for the microaggregation of albumin in the presence of the reducing metal are described.
Patent CH-608222-A5 (CH)
Title: Packaging, in particular for books
Inventor: BRIEGER ROBERT
IPC: B65D5/00
Filed: 1976-04-30
Abstract: The packaging for books or brochures is composed of corrugated-cardboard portions (1, 3, 4) which are connected to one another and are arranged with respect to one another such that, adjacent to a bearing surface for the book (9), they form flaps which are intended to be folded over the book. The corrugations of any two neighbouring flaps run at right angles to one another, with the result that the flaps on all four sides can be folded over along lines (5, 6, 7, 8) which are predetermined by the corrugations in the corrugated-cardboard portions. A large corrugated-cardboard portion (1), on the mutually opposite edges, at the longitudinal centre, of which there are fastened two smaller corrugated-cardboard portions (3, 4) of the same width as the book, is wider, in the direction parallel to the corrugations, than the bearing surface of the book (9). At each of the mutually opposite sides, this corrugated-cardboard portion forms a crease zone, by means of which the large corrugated-cardboard portion projects at the edge, beyond the corrugated-cardboard portion which was first of all folded inwards, with the result that the book corners are protected. <IMAGE>

Title: Regeneration process and appts - for ion exchange resins
IPC: B01J49/00
Filed: 1970-05-19
Granted: 1971-12-31
Abstract: Regeneration process is intended for resins used in the demineralisation of water by ion exchange, the regeneration product is injected in counter-current to the treated water and a back pressure is created by the injection of a neutral fluid directly and recovering it by nozzles situated just below the upper level of the resin. This back pressure is produce by recycling a fraction of the mixed effluents under pressure to the water contained in the exchanger at the start of the regenerating operation. The ion exchanger consists of a cylindrical tank with a bridging-piece to support the resin bed. Nozzles supported by the branches of a collector are provided just below the upper level of the resin. A closed circuit recycling system, with a pump, creates a back pressure zone above the level of the resin and tends to oppose too great an expansion of the resin during back-washing and regeneration. Good regeneration can thus be obtained without the necessity of using any additional fluid; there is, therefore, no supplementary consumption of water during the process.
