Patent DE-3608702-A1 (DE)
Title: Pumping device for delivering liquids
Inventor: DOERENKAEMPER WILHELM
IPC: F04B53/12
Filed: 1986-03-15
Abstract: In a pumping device for delivering liquids with a piston arrangement, formed from two coaxial delivery pistons, in a pump chamber, the suction line is assigned to one and the delivery line to the other of the mutually opposite end regions of the pump chamber, and the pump chamber is divided by the piston arrangement into a suction chamber containing the mouth opening of the suction line and a delivery chamber containing the mouth opening of the delivery line. The piston arrangement is provided with a passage duct in the second piston for a flow connection of the suction chamber and the delivery chamber during the delivery stroke of the piston arrangement. The result is an essentially continuous liquid delivery to the consumer both during the forward travel and during the return travel of the piston arrangement. At the same time, it is possible to work with a large-volume delivery stroke in the normal, low pressure range and, depending upon the counterpressure of the consumer, with reduced delivery volume and high delivery pressure.

Patent DE-3726257-A1 (DE)
Title: Medicament dispenser
Inventor: STOEHR GEB SCHMITZ
IPC: A61J7/04
Filed: 1987-08-07
Abstract: The electronic, time-controlled, automatic MEDICAMENT DISPENSER "automatic help", briefly called ezaMe, four times a day. Up to now, supply of tablets to many in- and out-patients has been possible only with daily expenditure of time by a large number of nursing staff and assistants. Many people that require help are unable to take their prescribed tablet doses in the proper, responsible way. There are no appropriate aids that provide help simply and reliably on an automatic basis. The ezaMe meets this large demand. Its four individual medicament rings with the reception compartments that are sealed individually and independently of each other supply the patient four times a day automatically at programmed times with AUDITORY-VISUAL and TACTILE aids. The patient requiring help is protected by the ezaMe against over- or under-supply due to wrong administration of the prescribed tablets. The nursing staff and assistants can supply the patients reliably and in advance with the tablet dose required for 7 days a week four times a day. This also represents a large cost and time relief for hospitals, social stations, nursing homes and domestic care. <IMAGE>
Patent DE-3729779-A1 (DE)
Title: Addition-subtraction circuit in 54321 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-09-05
Abstract: The addition-subtraction circuit according to the subject of the invention forms the subtraction result numbers additively, using a nine's complement circuit (8), which is combined with a straight-through circuit, and can thus be switched from passing straight through to nine's complementing and vice versa. For adding, the carry output (y) has high potential if the addition has a real carry. For subtracting, the carry output (y) has high potential if this circuit has only a circuit carry and thus no real carry. A subtraction therefore has a carry if the carry output (y) has low potential, and no carry if the carry output (y) has high potential. <IMAGE>

Title: Heat exchanger system having a cross-flow blower
Inventor: THIEN GERHARD DIPL ING DR
IPC: B60K11/04
Filed: 1988-04-26
Abstract: A heat exchanger system consisting of a cross-flow blower having an impeller, an air-guiding housing which partially surrounds said impeller, and an outlet housing which is additionally formed by a partition, ending in a tongue, between the inlet and outlet ducts and by two lateral parts arranged on the axial ends of this partition, and to which a heat exchanger is connected. Arranged in the interior of the impeller is at least one fixed flow-guiding vane which is located in the region between the tongue of the outlet housing and the impeller axis and is convex towards the axis of the impeller. The aim is, while retaining the good aerodynamic and acoustic characteristics, to implement combinations with heat exchangers whose end area compared to the impeller is very large. This is achieved by providing the heat exchanger, by means of zig-zag folding, with a relatively large effective end area. The heat exchanger preferably consists of two planar (flat) parts which are at an acute angle with respect to one another.
