Patent DE-2105342-A1 (DE)
Title: Vibratory separator for bulk material - having channel fitted with obstacles
IPC: B07B13/00
Filed: 1971-02-05
Abstract: Size and density fraction separation is effected by passage of the material through an inclined vibratory channel fitted with suitable obstacles for deflecting the loose flowing material. The obstacles repeatedly cause streams of the material, which were previously formed by subdivision into two streams at the crest of each obstacle slope, to join. When this occurs, the lighter particles tend to rise in the conical heaps of material formed, rolling away over their sides and passing through holes located in the dead angle behind the obstacles in the floors of the channels, falling into a collecting channel in which they move downwards, whilst the other heavy particles continue in their upward path in the upper vibratory channel. The method permits the highly efficient, large vol. separation of particles with small size differences and may be used even at elevated temps.

Patent DE-2144742-A1 (DE)
Title: Microporous resinous structures - made from emulsions of molten thermoplasts and incompatible liquids
Inventor: VIRNELSON R CRAIG
IPC: C08J9/00
Filed: 1971-09-07
Abstract: A resinous microporous structure, capable of absorbing and then squeezing out a predetermined material, is made by heating a thermoplastic resin to its fusion pt., forming an emulsion by mixing the molten resin with a liquid incompatible with the resin and then cooling the emulsion at a certain rate to form the cross-linked, microporous resin of predetermined pore size. The pore size is sufficiently small to reduce leakage to a minimum but recharging of the structure is still feasible. Microporous resinous structures useful for pads, buffers etc. are readily made by this process.

Patent DE-2334619-A1 (DE)
Title: Motor vehicle interior heating system - uses stored heat obtained from engine exhaust gases
Inventor: REUTER FRITZ
IPC: F01N3/02
Filed: 1973-07-07
Abstract: A storage heater, capable of storing heat up to 20 hours after the engine has been switched off, becomes recharged by the engine exhaust gas heat after approximately 10 minutes running. The storage heater is filled with an eutectic mixture such as NaF/CaF2/MgF2 and connected by a heat tube to the exhaust manifold spacer. The storage heater is surrounded by a sealed welded heat transfer jacket to form an evacuated heat contact chamber in contact with a condensation chamber, containing freon, surrounded by an electrical heater resistance. A second heat transfer jacket surrounds the heat transfer casing and contains an air fan and motor. The heat transfer tube is evacuated and filled with a small amount of sodium, which vapourises with the exhaust gas heat and rapidly conducts the heat to the storage metal. The heat contact chamber only returns the heat when the liquid freon is vapourised by switching on the heater resistance, the vapour filling the evacuated chamber to act as heat transfer medium. Air drawn in by the fan is heated and blown into the vehicle interior.
Patent DE-2343421-A1 (DE)
Title: Battery operated electric toothbrush - has pressurised toothpaste cartridge in handle
Inventor: HOFFMANN WOLFGANG G
IPC: A61C17/22
Filed: 1973-08-29
Abstract: The toothbrush handle consists of a hollow housing with internal spaces for batteries, the pressurised toothpaste cartridge and the motor. The cartridge is linked to the interchangeable brush head by a tube incorporating a valve. The tube joins a paste duct in the shank of the brush. The duct ends in branches in the brush head. The design eliminates the need to carry, pack or manipulate separate tubes of toothpaste particularly on journeys, and enables the user to dispense small quantities of paste repeatedly during use as required. The design is such that approximately half the space available in the housing is occupied by the pressurised toothpast cartridge.
