Title: Low density building material - using polystyrene and cement
IPC: C04B20/10
Filed: 1971-05-25
Abstract: Foamed polystyrene particles are coated first with an acid bitumen emulsion before being mixed with cement, sand and water in the usual way. The emulsion overcomes the hydrophobic property of the polystyrene, permits the polystyrene to be further processed immediately, and enables it to be pre-mixed with cement powder before transport to site where it can be further worked into the final mix.

Title: Double-walled sack - with valve formed automatically during closure of filling opening
Inventor: BUISE FRITS
IPC: B65D30/08
Filed: 1971-06-18
Abstract: The inner wall is made from a length of seamless i.e. extruded plastic foil tubing e.g. polyethylene and the outer of reinforcing material e.g. round woven jute or polypropylene fibre yarn, and both lengths of material have an extended tab section which is bent back and tucked into the neck on a 45 degrees fold line to form a self closing valve.

The top seams are close together but that of the outer bag which is esp stitched is outside that of the inner and the stitches pass through the free edge of the welded inner bag. The bottom seams are also close together and that of the outer also outside that of the inner but in this case of stitches are claer of the inner bag. Increased strength of assack, partic. for automatic rapid filling is obtd.

Title: Moulding ejection - with phased ejector rod operation by tilted striking plate or varied rod lengths
Inventor: HOERL GUENTER
IPC: B29C33/44
Filed: 1971-09-04
Abstract: Designed partic. for hard foams, such as polyurethane, as the half moulds are drawn apart, the support on one side carries a half mould with the embedded blank. As it draws back, the ejector rods strike a plate in a phased operation by using rods of different lengths, or a tilted striking plate to operate each rod in turn. The purpose is to provide a gradual release to overcome adhesion, and prevent the ejector rods from penetrating the moulding.

Title: Heat exchanger in motor vehicles for fresh air heating - operates in conjunction with the exhaust gas system of the internal combustion engine
Inventor: SCHMID WOLFGANG
IPC: F28D7/10
Filed: 1973-09-11
Abstract: The fresh air preheater is formed by an integral preformed and folded sheet metal plate. The formed heat exchanger casing is placed around the exhaust pipes. The fresh air is drawn in through lateral channels, passed through the gap between the outer shell of the heat exchanger and the exhaust pipe system which forms a deflecting wall and passed out in the lateral direction through the channel. The exhaust gas outlet system is also made by folding of sheet metal. The exhaust system and the outer casing are joined together at the base by welding; using a minimum amount of welding. The heated air can be supplied to the passenger compartment. No welded joints are made in the exhaust pipes in the region of the heat exchanger. This arrangement improves the operational reliability of the heat exchanger.

Title: Precast concrete beam mould - with weight-relieved struts for shuttering and grids hinged to toggle levers
Inventor: DOEMOEK STEFAN DIPL ING
IPC: B28B7/02
Filed: 1973-11-10

Patent DE-2420908-A1 (DE)
Title: Melting scrap lead - the scrap is wetted to bind the dust and after weighing is melted in a reducing atmosphere
Inventor: FISCHER REINHARD DR
IPC: C22B7/00
Filed: 1974-04-30
Abstract: In order to reduce the amt. of dust, usually associated with handling of the scrap lead, the scrap is sprayed with a wetting agent to bind the dust, and charged to vessels. The vessels filled with the scrap are weighed and charged to a tunnel furnace in which is maintained a reducing atm. and a temp. sufficient for melting the metal. After exit from the furnace the liq. metal is transferred from the vessel to a ladle and the emptied vessel is again weighed. Impurities floating in solid form on top of the molten lead are transferred after cooling by means of low pressure suction to a unit which is protected against dust. Process gives a simple weight control, avoids the formation of dust during unloading, and oxidation during melting. Oxides are removed without dust troubles.
Patent DE-2423357-A1 (DE)
Title: Light emitting diodes using gallium phosphide arsenide - zinc phosphide doping giving significant increase in luminance
Inventor: COLEMAN MICHAEL GARM
IPC: H01L21/22
Filed: 1974-05-14
Abstract: Semiconductor substrates made of III-V cpds., esp. GaP, GaAsxP1-x, or GaAs are heated in the presence of zinc phosphide to form a p-zone in the substrate surface. A germanium (or Si) disc is given an epitaxial layer of n-type GaAsP and a mask contg. windows. The substrate is then heated with Zn3P2 to 600-900 degrees C for up to six hours so that Zn diffuses through the windows forming both a p-n junction and also a transparent layer. Although there is a tendency for the GaAsP to decompose, any As lost is replaced by P so that the P content in the surface increases, giving increased penetration of light and a significant improvement in diode efficiency. Ten diodes made by this process were tested with a forward current of 10 A/cm2 and 50% had a luminance above 0.274 stilb, whereas in a comparative test using Zn-As, 50% of the diodes only had a luminance above 0.188 stilb. The absence of oxygen in the dopant eliminates unwanted red light.

Title: Viscosity meter using vertical tubes - includes washing, drying and filling arrangement for a capillary viscosity meter
IPC: G01N11/04
Filed: 1974-09-07
Abstract: The viscosity meter has a washing, drying and refilling arrangement, which comprises valves, pipes, joints and a suction tube, by means of which the solvent and the test sample is sucked away. After washing and drying of a tube extending to the lowest level, the test sample is brought into the meter by the aid of air pressure and suction and the correct level is controlled with the aid of a tube which extends only to the upper end of the sample bulb. The procedure for emptying the sample, washing the tube, drying and refilling is made automatic by the use of an electric programmer between the valve arrangement and the timing relay.

Title: Machine for spark erosive copying - has optical probe with follower mechanism using electric motors
Inventor: SAUER HANNS-JUERGEN DIPL ING
IPC: B23Q35/10
Filed: 1974-09-13
Abstract: The optical probe follows a given contour and transfers the movement to a rod or wire electrode. The electrode forms an electric circuit with the workpiece via a spark gap. The arrangement consists of a flat carrier for the master contour. This contour is followed by the probe. A rod is mounted with spherical ends in both the probe carrier and a fixed bearing in the machine frame. At a point between the two spherical ends, the rod engages with a block which is mounted in two co-ordinate slides. The movement of the block is a scaled down pattern of the master contour. This movement is transferred via linkages to the electrode drive.
