Title: Heat resistant polymer for battery conductors - with added polymethacrylic acid ester
Inventor: METZLER OTTO
IPC: H01M2/14
Filed: 1973-09-15
Abstract: In the parent patent a covering for the reactive material of a lead battery is made by hot or cold pressing sintered micropowders of oxygen/acid-resistant polymer into the desired microporous shape. In the addn., 1-20 pref. 10-15 wt. % of a micro-powdered polymethacrylic acid ester is added to the polymer granulat before moulding. The higher the additive content in the basic polymer the higher is the heat resistance, up to 90 degrees C and over. In place of sintering the granulate, the mixt. can also be combined by an oxygen/acid-resistant adhesive.

Title: Sliding contact - is provided with a sintered tin coating contg crystalline graphite
Inventor: HECK FRIEDRICH
IPC: H01H1/027
Filed: 1974-03-20
Abstract: Sliding contacts are produced by applying a Sn or Sn-Pb coating to the metal substrate which is electrically conducting. The Sn coating is given a low friction coefficient, good solderability and resistance to oxidation by incorporating crystalline graphite in the coating by using a polishing medium (tumbling polishing) containing graphite powder, whereby the surface is at the same time strain hardened. Pref. the Sn coating is sintered before applying the tumbling polishing step. The Sn coating is applied by electrodeposition and in the presence of a fluxing agent, sintered at max. 150 degrees C. The metal substrate, which is pref. brass, is provided with a Pb or Sn-poor Pb coating either by electrode-position or be weld deposition prior locating with Sn. The substrate contact faces may be coated with a layer of 60/40 SnPb (simplex) by weld-deposition, or in two steps (Pb coating followed by Sn coating) using Duplex with pure Sn (simplex) after which the surface is roughened by using corundum and tumble-polishing using a medium contg. graphite powder, whereby graphite is incorporated in the coating, and strain hardened. Pref. 0.15-0.20 per mille graphite are incorporated, and in addn. Ni-carbonyl and/or Ag.

Title: Two-part support structure for dental implant - has spiral base-part for dental support inserted
Inventor: GRABOSCH REINHOLD
IPC: A61C8/00
Filed: 1974-03-26
Abstract: The implantation consists of two parts, i.e. of a preferably spiral part, which is relatively easy to implant into the gum, and a support-element for the dental implant, to be inserted after gum has heated after the implanting of the first part, which is made of high-grade alloy steel. This method of using an alloy steel spiral base has little adverse effect on the bone tissue. It provides pressures caused by chewing during the settling in period and does not leave such a broad scarred area if the tooth is damaged or lost.
Patent DE-2425113-A1 (DE)
Title: Machine wear measured by isotopes in oil circuit - using oil pipe passing through sodium iodide crystal detector
Inventor: SCHMIDT GERD
IPC: G01N3/56
Filed: 1974-05-24
Abstract: A device for measuring the wear of a machine part by measuring of the radioactive isotopes incorporated into the surfac elayer of the part, worn away and transported, e.g. in the lubricating oil, comprises a measuring head with a scintillation crystal. A sodium iodide crystal is used, with a transverse passage through it, through which a straight length of pipe is passed; the oil containing the radioactive worn particles is passed through this pipe. In the preferred arrangement, this pipe is vertical, with its inlet at the top, outlet at the bottom, and pref. also an upper vent pipe leaving upwards above the oil level to atmosphere or alternatively back into the oil circuit. Esp. for wear measurements in which the surface zone of the machine parts have been irradiated by heavy charged particles from an accelerator to produce radio isotopes in the surface. The resultant activity is about 1000 times less than that produced by an earlier method using thermal neutrons. Applicable to automobile engines. A simple tube replaces the earlier arrangement of a complicated measuring chamber. A higher concentration of worn particles and thus higher sensitivity is achieved. Lead shielding around the measurement head can be considerably reduced, thus saving in cost and weight. Contact surface between the medium, which possibly is hot, and the measuring unit is smaller, so that cooling is simplified. Flow resistance is reduced and thus the readings are virtually unaffected by operating conditions. Because the pipe is vertical, worn particles do not accumulate in it.
