Title: Pump with adjustable throughput e.g. for vehicle
Inventor: REMMLINGER ULRICH DR
IPC: F04C14/22
Filed: 1997-05-30
Abstract: The pump supplies a load via a pressure line (1) from which a return line branches off.

Title: Production of seat and back cushions with profiles to suit an individual patient
Inventor: PREISLER BENEDIKT
IPC: B68G7/00
Filed: 1997-09-17
Abstract: Pad carrier shells (21,22) on a vacuum chair are adjusted to suit the patient and pads are adapted to the body shape before holding the created shape with vacuum. A mold shell is formed around the pads and reference lines established. The mold is filled and the resulting molding forms a positive mold. A negative cushion profile is thermoformed onto the positive mold and cushioning material formed onto the rear side. The resulting cushion is then mounted in a shell. An Independent claim is made for equipment to mold the cushions. Preferred Features: A vacuum chair is used with seat and back pads on adjustable supporting shells. Pads have an elastic, airtight cover (29) and a non-compressible filling (28) of spherical particles, 2-8 mm in diameter. Pad supporting shells (20) are adjusted by an electric motor. Reference lines are established by molding two removable reference bars into the positive mold, one (51) horizontal near the seat cushion and the second (52) in the sitting plane of the patient. The inclination of the of the second reference bar is measured before removing the positive mold from the pads and used to reproduce the position of the positive mold. During machining of the positive mold the latter is held on a measuring table with the inclination of the second reference bar corresponding to that measured during casting. A mounting shell is positioned on the measuring table and the upper edges of the finished seat and back cushions are drawn on the positive mold.
