Title: Separating packaging vessels deep drawn in continuous film - rows sheared first, transferred to stamping unit and packed
Inventor: WALTER KURT ING GRAD
IPC: B29C51/44
Filed: 1975-02-15
Abstract: The separating device for the vessels formed in a continuous run of film by a press for deep drawing packagings, has a knife extending across the full width of the sheet of film, so as to cut off a row of vessels; together with a feeder which progresses the sheared-off row through a transverse guide to a shear for cutting out the separate vessels. In the transverse guide a centralising tool lines up the strip for the shear, which works with a pinking tool for punching out a wedge-shaped section from each end of the cutting line, in the two edges of the strip. Expensive tools subject to heavy wear are dispensed with, no pinking cut or only a very slight one being necessary. The packages are cut out absolutely centrally and changeover to a different rim format is simple.

Title: Gas washer for removal of fine solid or liquid particles - includes a gas stream divider giving reduced overall pressure drop
Inventor: GLASS REINHARD ING GRAD
IPC: B01D47/06

Title: Temp. and voltage compensated electret sensor - has sensing circuit connected to two conductive layers for specified compensation
Inventor: TAYLOR ALLEN L
IPC: G01L1/16
Filed: 1976-02-12
Abstract: The sensor has an electret layer of polarised material with both piezoelectric and pyroelectric properties. The layer generates electrostatic charges of opposite polarity on its surfaces under the effect of temperature and voltage variations. One side of the electret layer is in close planar contact with a conductive layer. A second electret layer of the same properties is arranged parallel to the first layer and has also a second conductive layer. A third conductive layer is sandwiched between the other sides of the two electret layers. An electronic sensing circuit (10) is connected to at least two conductive layers in such manner that, when the electret layers are exposed to identical temperature changes and opposite voltage changes, the circuit picks up the electrostatic charges, while not responding to electrostatic charges due to the other change of the two states.

Title: Metal extraction from industrial wastes - using electrolytic treatment by circulation through revolving granular cathode
Inventor: KAMMEL ROLAND PROF DR ING DR
IPC: F02B3/06
Filed: 1976-04-24
Abstract: Diluted effluents with a metal contact are circulated by a pump through a revolving perforated tube which is surrounded by a granular cathode. A high flow velocity is maintained during the electrolytic treatment. AFter the metal content has been reduced below the desired level, the effluents are treated chemically for detoxification and neutralisation, and/or by ion exchangers for removal of the residual metal content. This is a simple, functionally reliable and practically continuous process for a complete recovery of the metal in industrial wastes in a metallic form. The treatment leaves no metal content in the sludge and the effluents can be safely discharged to the drainage system.
