Patent AT-E50029-T1 (AT)
Inventor: BROWN CHARLES WILFRED
IPC: F04D29/22

Abstract: A centrifugal pump utilizing laminar action induced by a vaneless impeller and having a minimal drag front plate which cooperates with the circular rotor. The smooth surface of the concave face of the circular rotor has no protrusions or vanes and approximates an Archimedian curve. Material entering the intake port of the front plate is diverted about the rotating circular rotor and redirected in an outwardly direction along the minimal drag interior surface of the front plate to the discharge port of the output housing. The narrowing of the interior surface of the front plate in a radially outward direction with respect to the concave face of the impeller helps the pump to maintain a constant volumetric flow rate. Inasmuch as the "redirecting" of the incoming material stream follows an approximate Archimedian spiral, the pressures applied against the impeller and the forces acting centrifugally on the material stream join to produce the optimum imparting of kinetic energy to the material stream for the particular impeller speed. As a slurries pump, the vaneless design permits any particulate size that can clear the discharge port of the pump to safely transit through the pump without maceration or undue agitation. As cavitation is totally absent, the pump can easily handle the movement of fragile, volatile or gaseous materials and can be operated over a wide range of speeds, matching desired feed without undue loss of efficiency. Lacking vanes, the impeller offers very low starting torque under a loaded condition.

Abstract: The invention is aimed at a composition for the enlargement of the female breast. Until now, not entirely hazardless surgical interventions in which silicone materials were implanted have been necessary for achieving a visible effect. Furthermore, similar effects have occasionally also resulted in the case of hormone treatments which, however, are a serious intrusion into the body metabolism. The invention takes remedial action here in that it dispenses with surgical interventions and hormone treatments, and makes available a simple composition which is easy to apply, which includes the following basic substances: a triglyceride mixture containing 25-35% by weight of oleic acid, 25-35% of stearic acid, 15-25% of palmitic acid, 10-20% of liquid paraffin and 1-10% of linoleic acid. <IMAGE>

The mixture is filtered through a filter (21) disposed in the drum. Filter liquid is discharged to the outside. The particles are prevented from passing through the filter and remain in the drum. Thereafter, the particles are heated and dried by a heating jacket (12) on the drum while the drum is caused to assume a horizontal position and being rotated. The drum is then inclined such that the initially upwardly directed end thereof is directed obliquely downward. Thereafter, an agitating blade (25) and sweeping blades (26) on the inner end of the rotary shaft (24) is rotated and shifted axially, whereby the dried particles are agitated and swept, to be discharged to the outside.

Abstract: A read apparatus for reading a record carrier (1) having a concentric track pattern comprises a scanning device (2, 3) for reading the information, and a separator circuit (4) for extracting a periodic synchronising signal (Ps) from the information read. By means of a servo system, which inter alia includes a drive motor (9) for driving the disc 1 and a control circuit (5), the rotational speed of the disc is controlled so as to maintain the periodic synchronising signal (Ps) in synchronism with a reference signal (Pr). The circuit (9a) rejects those signal components in the control signal (U) for the motor (9) which are caused by an eccentric position of the centre of rotation of the disc relative to the track pattern. This prevents these signal components from causing an unnecessary dissipation of electric power in the motor, yielding a substantial improvement in motor efficiency.

Abstract: In an instrument having an interrogating optical beam for the measurement of various optical properties of the eye, a detector is disclosed for triangulating the towards and away distance of the eye from the objective of the measurement equipment thus utilizing the beam for serendipitous purpose of ranging. A photosensitive detector having two photosensitive elements is placed in a plane which includes the optical axis of the interrogating instrument and the detector. The detector is mounted towards the eye with the division between the two photosensitive surfaces normal to the plane including the interrogating optical beam and the detector. Typically, the detector has line of sight off axis with respect to the interrogating beam and intersects the axis at the preferred position for eye placement. An imaging lens relays a conjugate image of the detector to that point in space on the optic axis in front of the eye where ultimate placement of the eye for measurement is desired. By the simple expedient of moving servomotor to obtain a quality of signal between the photosensitive portions of the detector, rapid positioning of the eye can occur.
