Title: Fluid pump
IPC: F16N13/04
Filed: 1980-03-13
Abstract: A fluid pump for lubricants which comprises a drive shaft (3) mounted in a stationary housing (2) and driving an axially connected eccentric control shaft (6). The control shaft has a rotatable collar (8) mounted on it which forms a "cylinder ring" and has a radially inwardly extending bore which cooperates with a piston (10) pivotally mounted on the housing by means of a pin (12) parallel to the drive shaft (3). The engagement of the piston with the bore prevents the cylinder ring from rotating with the control shaft so that rotation of the drive shaft, and therefore the control shaft causes the cylinder ring to reciprocate relative to the piston. <IMAGE>

Title: A spray gun
IPC: B05B15/55
Filed: 1980-03-18
Abstract: A spray gun has a body 10 which defines a cylindrical space 20 therein, within which an elongated spool is contained, the spool 22 extending substantially from a rear end of the gun to a front end, at which is located an apertured nozzle cap 28. The spool is biassed away from the cap by a resilient means 39 and has a central conduit 32 therein having a lateral portion which in a selected rotary position of the spool registers with a port 18 in the body in communication with a feed passage for material to be sprayed. The body also has a gallery 40 therein forming part of a passageway for compressed gas or air and extending to an annular space 48 defined between the spool front end and the nozzle cap. An orifice 24 in the front end of the spool registers with the nozzle cap aperture. Spring 39 urges the spool against a cap 35 which can be adjusted to vary annular gap 60 through which air leaves the space 48. In a further rotary position of the spool cleaning liquid is supplied to the air passage 40. <IMAGE>

Title: Nebulizer device
IPC: A61M16/12
Filed: 1980-07-24
Abstract: A nebulizer device for producing an aerosol spray via a flow of gas at varying oxygen concentrations is disclosed. The nebulizer device comprises a body defining an initial nebulization chamber, a subsequent baffling chamber and a venturi formed therebetween. Air intake ports are disposed on the body adjacent the nebulization chamber for providing the nebulization chamber with air in predetermined quantities. Regulating means are disposed about the nebulization chamber for regulating the flow of the air through the intake ports. An aerosol system for producing an aerosol of fine particles of liquid is located in the nebulization chamber upstream of the venturi such that the flow of the aerosol spray through the venturi encourages the atmospheric fluid to enter the device through the intake ports thereby diluting the aerosol. The venturi is located downstream of the intake ports and increases the flow rate of the atmospheric fluid through the intake ports. The baffling chamber is provided with an outlet for directing the aerosol out of the baffling chamber.

Title: Fluidic-electric sensor for determining the composition of gas mixtures
Inventor: ZIPSER LOTHAR
IPC: G01N29/00
Filed: 1982-05-28
Abstract: The invention has the aim of simplifying the determination of the composition of gases, especially the moisture content of the waste air of an industrial drying plant, and thus enabling minimisation of the energy consumption of such plant. The sensor is to be usable in extreme environmental conditions and to supply electric frequency-analog signals which can be transmitted without additional amplification over at least 100 metres by ordinary leads and can then still possess specific, if necessary standardised, amplitudes and frequency values. As sensor there is used a flat fluidic oscillator in which an inlet nozzle is coupled through resonance chambers with an outlet nozzle. Means for jet smoothing are provided in the inlet nozzle. The defining surface of the resonance chambers are adjustable partially or wholly perpendicularly of the oscillator plane and formed as pressure-sensitive devices. <IMAGE>
