Patent DE-3914652-A1 (DE)
Inventor: MANN RALF DIPL ING
IPC: F04D29/12
Filed: 1989-05-03
Abstract: Centrifugal pump, especially for pumping hot liquids, with at least one shaft passage to the outside through the pump housing and sealing of the shaft passage by means of a face seal (14, 15) and a scavenging and cooling flow for the face seal derived from the pumped medium. This flow is drawn from a higher pressure chamber, the pressure chamber (3), spiral chamber (6) or spiral side chamber (7) of the pump and led through at least one duct (8) provided in a housing cover (10) to an annular gap (13) formed between the housing cover (10) and an intermediate housing (11) inserted from the impeller wheel side into the housing cover, and from this close to the sealing face of the face seal (14, 15) into the seal chamber containing the face seal.

Patent DE-4006059-A1 (DE)
Inventor: ADACHI TAKESHI
IPC: H04N5/60
Filed: 1990-02-26
Abstract: An IF signal is separated into a video component and a color and sound component through first and second band- pass filters 3 and 4, amplified by first and second amplifying circuits 5 and 10 then detected in first and second detecting circuits 7 and 11. The gains of both amplifying circuits are controlled by an AGC voltage derived from the output of the first detecting circuit 7. As the video component and the color and sound component are separated from each other they will not interfere in the amplifying stage 1. The color picture quality, the cross color obstruction and the color and sound beat obstruction may all be improved. The buzz component of the sound may be reduced. Other advantages are described. <IMAGE>

Title: Fuel injection pump - has additional oil-filled chamber formed by pump chamber and piston
Inventor: ROESGREN CARL-ERIK
IPC: F02M63/00
Filed: 1990-08-23
Abstract: The pump consists of a cylinder (1), with pump chamber (6), with fuel inlet and outlet channels (3, 7), and a movable piston (2).
