Title: Breaking emulsion of oil and water
Inventor: KURZ CHRISTIANE
IPC: B01D17/04
Filed: 1995-10-19
Abstract: The emulsion is frozen at one stage in sequence of separation processes. A part of the emulsion is broken by freezing and subsequent thawing in a continual process using a chilled roller or disc which rotates and dips into the emulsion bath. The freezing emulsion is lifted above the surface of the fluid and then separated by a scraper. The roller or disc are chilled by a refrigerator, the waste heat from which subsequently thaws the frozen emulsion.

Patent DE-19611763-A1 (DE)
Inventor: WELLER ELMAR
IPC: A61N5/06
Filed: 1996-03-26
Abstract: The invention concerns a radiation apparatus for whole-body radiation with a plurality of mutually parallel rod-shaped low-pressure lamps (14) which are disposed at a mutual lateral spacing in a radiation field (12) with a defined radiation direction (26) for emitting UVA and UVB radiation, and with at least one high-pressure burner (16) disposed in a partial region (18) of the radiation field for emitting UVA radiation. According to the invention, in order to optimize the spectral distribution even for less sensitive areas of skin, the high-pressure burner (16) is set back in the radiation direction relative to the low-pressure lamps (14). The low-pressure lamps (14) extend beyond the radiation field partial region (18) containing the high-pressure burner and are irradiated there by the UVA radiation of the high-pressure burner (16) in the radiation direction. The radiation intensity of the high-pressure burner (16) is set at a level which is higher by a multiple than the low-pressure lamp arrangement (14).

Title: Medullary pin for fracture in hip region
Inventor: AHRENS UWE DIPL ING
IPC: A61F2/30
Filed: 1996-05-06
Abstract: The basic pin element can be connected at top and-or bottom ends by inner and outer cones (3,4,6) or threads at both ends (10) to a second implant component e.g. knee or hip prostheses. The bearer of the basic element has entry and three relatively angled outlet holes so the pin can be inserted at selected angle, the bearer fitted with end connections (6) for the second implant etc. The pin admission hole conforms to the profile of the peg, using a slot in the bearer for a locking screw serving to transfer moment to the bone itself. Run into bearer at the required angle, the pin reaches up through the femur neck into the head and so forms a cantilever taking up bending and rotation forces in this region, using the bearer holes to place the pin at the angle required.

Patent DE-19623828-A1 (DE)
Inventor: MEIER THOMAS DIPL ING
IPC: H02J1/00
Filed: 1996-06-14
Abstract: A circuitry generates an output voltage (V-) having a first polarity relative to a reference potential (P) from an operating voltage (V+) having a second polarity relative to the reference potential (P). The basic operation principle of this circuitry consists in loading a first capacitor (C1) with a positive voltage relative to the fixed reference potential (P) by applying an overvoltage to a coil (L), after the coil is switched without current. During the on-phase of a transistor (T), the first capacitor loads a second capacitor (C2) with a negative voltage relative to the fixed reference potential (P), this negative voltage being accessible from the outside. An electric resistance (R3) is connected between the output terminal (A) of the circuit and the control conductor (E2-G) of the transistor (T).

Title: Highly integrated semiconductor memory manufacture
IPC: H01L21/8242
Filed: 1996-09-30
Abstract: The memory has word and bit lines and memory cells in silicon substrate, each with a MOS selection transistor and buried capacitor.
