Title: Extruded thermoplastic foam - allowed to expand in reduced pressure of mould under wide slits
IPC: B29C44/42
Filed: 1972-01-04
Abstract: Designed to provide foam material for packing and roof insulation applications, the thermoplastic material with a foaming agent is passed under pressure through a series of wide slits into the mould, where dividing walls are used to pack the material to an even density and distribution so that it can expand to fill the space available. Materials which can be used include polystyrenes, polyolefins e.g. polyethylene or polypropylene, polyamides and ABS copolymers. The only interruption in the process is when the feed is halted to pass a new mould under the slits.

Title: Fibre production - from molten matter in crucible surrounded by protective gas
Inventor: DOERRE ERHARD DR
IPC: C03B37/06
Filed: 1972-02-05
Abstract: Designed to convert to fibres inorganic material with a high content of aluminium oxide or other oxides, the material is melted in a crucible of tungsten, molybdenum niobium, tantalum or their alloys, which is surrounded by a protective gas of 80-98% N2 and 2-20% H2.

Title: Scraper bridge steering system - for multiple drive motor bridges on wide settling tanks
Inventor: MARZLUF WERNER
IPC: B01D21/20
Filed: 1972-08-26

Title: Recovering red phosphor from defective colour TV tubes - using hydrogen peroxide soln.
Inventor: BAYER RAGEN
IPC: C09K11/01
Filed: 1972-10-13
Abstract: Recovery of red phosphor based on Y, La or Gd cpds. (pref. oxides, vanadates or oxysulphides) activated with rare earth elements, which is used together with blue and green sulphide phosphors in colour TV tubes, is carried out by loosening the phosphor layer with an aq. soln. contg. 0.1-30 vol. % H2O2, and opt. alkaline accelerators, various stabilisers and complex-forming cpds. By this method, the valuable red phosphor is recovered selectively, because it dissolves in H2O2-contg. solns. more rapidly than the other phosphors.

Title: Spacer for holding additional concrete reinforcing bars - is flat plate with support projections made from pressed sheet steel
Inventor: HAYESSEN WOLFGANG DR-ING
IPC: E04C5/18
Filed: 1973-07-05
Abstract: The flat support plate is placed edgeways between the reinforcing bars which are to be kept apart. The plate has a number of cutouts for allowing passage of concrete. The projecting lugs on the plate edge are sufficiently high to form steps for holding the round bars. This plate is used in conjunction with bent bars which hold the reinforcing rods in the correct position. The plate has bent over lugs which are at right angles to the plane of the plate. This assists in holding the plate at right angles to the bars and in the vertical plane. Thin projections can be bent in the manner of plates and these thin sections can be bent in the manner of wire around the reinforcing bars for holding purposes. The lower projections of this support plate are used for positioning the plate type spacer and a concave seat can be pressed into the upper edge of this plate. This plate is used for holding additional reinforcing bars, especially in the region where tensile loads are expected.

Title: Combined feed launder and sand trap - for effluent treatment plant, designed for all weather use
Inventor: WEBER EMIL
IPC: B01D21/00
Filed: 1973-07-31
Abstract: In a launder for an effluent treatment plant, particularly a sand trap therefore, having in known manner a sedimentation trench extending along its whole length, together with a conveyor for scraping away the sediment, the conveyor is a scraper chain unit, the conveying section of which is guided in the sediment trench and in a trough extending from from the base of the trench, to which it is connected in the region of the launder inlet, to a discharge outlet aligned with the trough and above ground level. Thus the sand scraper conveyor is not only free from operational failures, but can be used all the year round without difficulties caused by weather conditions e.g. freeze-up.

Title: Continuous for accumulator rapid charging cct. - has Zener diode as reference coupled to thyristor switch gate to charge on voltage drop
Inventor: SCHNEIDER ARTHUR
IPC: H02J7/00
Filed: 1973-12-22
Abstract: The rapid charging circuit for accumulators allows the accumulator to be recharged automatically as soon as the actual terminal voltage falls below the required level. The accumulator is coupled over a thyristor switch and indicator lamp to the rectifier output. A reference voltage is applied to the thyristor gate such that its amplitude is greater than the required charging voltage by an amount equal to the voltage needed to switch on the thyristor. The reference voltage is derived from a zener diode coupled between one accumulator pole and a resistor, coupled to the more positive terminal of the rectifier. The zener diode is connected via a voltage divider to the thyristor gate.

Title: Carbon-granule microphone with textile web - closes carbon chamber axial moving electrode and also acts as acoustic damping
Inventor: LANGE HUBERT
IPC: H04R21/02
Filed: 1974-05-31
Abstract: The carbon-granule microphone has a main body (5) with mounting pieces (4) and containing the carbon granules (7).
