Title: Automatic cleaner for dialysers for artificial kidneys - incorporating programming of washing, rinsing and sterilising several dialysers simultaneously
IPC: A61M1/16
Filed: 1975-05-07
Abstract: Appts. for cleaning dialysers for artificial kidneys incorporates an electronic time-switch and a programmer which operate valves in pipes connected to the blood and dialysate circuits, and to a water supply and containers of wash liq. and sterilisation liq. The containers have a transparent wall. There are supports for the dialysers, press. regulators, and indicators which show the different phases of the cleaning cycle. The water-pipe has two branches, each with a Venturi mixer, one connected to the wash liq. container and the other to the sterilisation liq. container. The programmer divides the cycle into phases - washing the blood and dialysate circuits with water, washing the dialysate circuit with diluted hydrogen peroxide three times and following each time with a water-wash of both circuits and finally circulating a sterilisation liq. pref. formol. The cycle can be extended if necessary. The invention permits simple safe and automatic washing and sterilisation of several dialysers at once, thus extending their use, which is important because they are relatively costly.

Title: Rotating electric contacts - made of conducting metal contg. easily oxidised alloying element subjected to internal oxidn.
Inventor: GUIRALDENQ PIERRE
IPC: H01H1/021
Filed: 1975-11-05
Abstract: Elements are made of an alloy of a metal which is a good conductor, e.g. Cu, Ag or Au, with a small amt. of a substance more readily oxidised than the metal; and the contact surface of the elements is heated to produce internal oxidn. Heating is pref. limited so the thickness of the layer of internal oxidn. does not exceed a few hundred microns. Heating is pref. in an oxidant gas, e.g. air at 800 degrees C., or the contact surface can be covered with an oxide thermally decomposed in presence of the base metal to form O2 diffusing into the latter. Pref. elements consist of copper used with copper oxide or nickel oxide, with heating to 1000 degrees C so O2 diffuses into the Cu. Alternatively, the substance more readily oxidised is pref. Be, Cr, Co, Ni, Si, Be-Co, or Ni-Si; when the base metal is Ag or Au, Cu may be used as the addn. Contact elements have good conductivity and do not undergo seizure or microwelding. They are suitable for contacts moving at slow speeds and/or for intermittent use.

Abstract: The coin sorting device, e.g. for checking the validity of coins (2) inserted in a coin-operated device, is responsive to the thickness (ep) and diameter (D) of the coins (2). It employs a capacitor (3) with the coins forwarded between the two capacitor plates and the capacitance variations being monitored. The capacitor (3) may form part of an oscillator circuit, so that the capacitance variations cause the oscillation frequency to vary correspondingly, with a counter recording the frequency variations. Pref. the two capacitor plates are applied to opposing sides of a coin shute (1) of insulating material, the variation in capacitance in response to passage of a coin (2) being related to the square of the coin diameter (D) and its thickness (ep).

Filed: 1977-01-12
Abstract: In order to provide chain tracks which can be made available in different widths with a low degree of expenditure and using as few components of different kinds as possible, a chain track whose chain elements have tubular bodies (1) which are arranged transversely with respect to the running direction and are connected in the running direction by means of connectors (3, 5, 6), is designed in such a way that, for the purpose of widening, further tubular bodies (1) can be attached transversely with respect to the running direction by means of further connectors (6). All the tubular bodies (1) preferably have the same width. The connectors (3, 5, 6) are connected to the tubular bodies (1) and the chain elements adjacent in the running direction by means of bolts (8). The length of the bolts (8) is matched to the width of the chain. In this way it is possible to provide chain tracks of different widths using uniform components, only the bolts (8) having to be adapted to the selected width.
