Patent DE-3904352-A1 (DE)
Title: Method for regenerating a particulate filter arranged in the exhaust of a diesel internal combustion engine
Inventor: BOLL WOLF DR
IPC: F02B3/06
Filed: 1989-02-14
Abstract: A description is given of a method for regenerating a particulate filter arranged in the exhaust of a diesel internal combustion engine by burning off the particulates with the aid of a burner. In order to minimise fuel consumption for the regeneration phase, the proposal is to allow a predetermined operating period to elapse and to initiate the burn-off process only when conditions for regeneration of the particulate filter are optimum. Moreover, the fuel supply is controlled in such a way during the burn-off process that the exhaust-gas temperature cannot exceed a predetermined limiting value, the duration of the burn-off process being determined as a function of the variables exhaust-gas temperature, residual oxygen content in the exhaust gas and filter burden.

Patent DE-3915039-A1 (DE)
Inventor: WAGNER RUDOLF
IPC: C30B25/14
Filed: 1989-05-08
Abstract: The elevation platform (1) has a workpiece support (5) guided movably up and down in a housing (2), this support making it possible for a disc-like workpiece (6) to be transported into a process chamber (36) of a vacuum installation. In order to correct the position of the workpiece (6) deposited by a machine onto the workpiece support (5) and to secure the workpiece during transport, use is made of holding members (30) arranged on opposite sides on the elevating platform (1). These each consist of a bar (20) on the end of an extension arm (14) which is arranged on a shaft (10) mounted rotatably in the elevating platform, this shaft being rotatable within a swivel region by means of a motor (12), in order to bring the holding member (30) into one of two different positions. The position of the workpiece (6) on the workpiece support (5) can be corrected by means of two holding members (30) arranged next to one another on the one side of the elevating platform and a holding element arranged on the opposite side of the elevating platform. A disc (29) arranged at the end of each bar (20) of the holding member (30) engages over the edge of the workpiece and secures this during upward conveyance. The holding member (30) is then swivelled outwards by means of a motor and comes to lie with the disc (29) under a cover (34), so as to be protected from the effects of the surface treatment of the workpiece (6) in the processing chamber (36). The workpiece support (5) includes a heating means (50) having a heating spiral (56) arranged inside a groove (52) in a plate (51). Flowing through the groove (52) is a gas which emerges through small bores provided in the plate (55) covering the groove, so as to form a gas cushion which serves as a heat-conducting means and for a uniform heating or cooling of the workpiece.

Title: Mattress with variable pressure elements to prevent bedsores - has chambers expanded or contracted by vaporising or condensing inert chemical using peltier elements
Inventor: WALDNER MICHAEL
IPC: H01L35/00
Filed: 1991-04-16
Abstract: The mattress chambers (1, 3) are pressurised when the chemical within is heated and vaporised. These chambers then support a body lying on the mattress. The chambers (0, 2) are depressurised when the chemical is condensed. Pressurised and depressurised chambers alternate. Pressure loading-unloading changes about every 15 minutes. The heating and cooling is effected by passing current through Peltier elements. Most of the heat required to evaporate the chemical and inflate chambers comes from that due to chemical condensation in neighbouring chambers. This heat is conducted through a thermally conducting plate under the mattress. ADVANTAGE - Prevents bedsores without using apparatus with mechanical pumps or very intensive manual methods requiring skilled staff.
