Title: Dishwasher circulation pump driven by sync. motor in either direction - has elliptical pump chamber and axial inlet and twin outlets tangential to chamber walls in major axis direction
Inventor: PANSA ANDREAS
IPC: F04D29/48
Filed: 1992-10-01
Abstract: The circulation pump which delivers independently of rotation direction, has a pump chamber (6) with impeller (4) and an axial inlet centrally located on the front face. The outlet is tangential to the chamber walls and is tapered (10). It is divided into two channels by a guide wall (7). The chamber walls themselves are slightly elliptical in contour with respect to the impeller axis, there being the greatest clearance at a point (3b) diametrically opposite the guide plate in the outlet and the least clearance at 90 degrees in either direction from this. The minimum cross-section of each of the tapered outlet channels is about equal to that of I/D of the outlet union. ADVANTAGE - Reliable with good delivery.

Title: Flange profile for the mutual fastening of air-duct portions
Inventor: DRAVENAU PAUL
IPC: F16L23/02
Filed: 1993-01-30
Abstract: The invention relates to a flange profile for a flange connection for the mutual fastening of cross-sectionally essentially rectangular air-duct portions consisting of sheet metal. The object of the invention is to ensure secure mounting of the flange profile on the air-duct portion, the intention being, in particular, for a durable, air-tight connection to be produced between the flange profile and the air-duct portion and between the air-duct portions themselves. In this arrangement, the sealing action of the sealing composition is to be durably elastic, and account is to be taken of fitting properties, adequate for technical requirements, in manufacture and mounting of the flange profile. The object is achieved according to the invention in that the vertex of the bead rebate is covered by an elastic layer, and the layer is formed so that it bears elastically and without interruption on the inner side of the opposite leg part. <IMAGE>

Title: Bicycle trailer
Inventor: KOLB CHRISTIAN
IPC: B62D63/06
Filed: 1993-02-27
Abstract: The invention relates to a bicycle trailer known from the prior art. In addition to its cost-effective production the design according to the invention is intended to have a multitude of applications, a particular object being the transportation of small children. A multiplicity of bicycle trailers known from the prior art and the chassis of which are provided with an upwardly open box are used solely for the transportation of goods. The safe transportation of small children in so-called child seats with integrated seat belts, such as are used in cars and on bicycles, or in a cart or pram is not possible unless done by do-it-yourself construction, which is expensive. In contrast, the design according to the invention permits, in addition to the conventional way of transporting goods, the following transportation combinations:   1. The transportation of one small child in a car or child's bicycle safety seat. 2. The transportation of two small children, both sitting in the direction of travel, as described under 1. 3. The transportation as under 2., but facing each other, as described under 1. 4. The transportation of a small child, as described under 1., in conjunction with a container for holding small items, such as, for example, a picnic hamper. 5. The transportation of a small child or infant sitting in a cart or lying in a pram.

Title: Deburring tool
Inventor: BEIER HANS-MICHAEL DR ING
IPC: B23B51/10
Filed: 1993-03-06
Abstract: The invention relates to a deburring tool which is moved in a rotary and/or translatory manner during use. It serves to deburr abutting edges of bores and/or grooves as well as abutting edges of surfaces. It has a tool shank 1 on which one or more cutting edges 3 are arranged so as to be distributed axially with regard to the longitudinal axis 4 and/or about the longitudinal axis 4. Provided in the end carrying the cutting edges is a central recess 5 in which an elastic supporting body 6 sits. A cutting-edge body 7 having the cutting edges is supported on the supporting body 6. The cutting edge is arranged on the section of the cutting-edge body projecting radially from the tool shank 1. By this arrangement, improved support is achieved in so far as movements of the cutting-edge body 7 are permitted which enable effective deburring even of abutting edges lying in the space. <IMAGE>

Title: Arrangement for compensating axial forces on roller grinding mills
Inventor: FRITZSCHE THOMAS
IPC: B02C4/28
Filed: 1993-05-04
Abstract: The rollers are mounted on bearing bodies in the frame. The axes of the rollers, on the line of action of which the axial forces act, do not run through the bearing point of the bearing body in the frame. As a result there is a tipping moment. The aim of the invention is to develop an arrangement for compensating this axial force, by means of which the tipping moment acting on the bearing of the bearing body can be rendered ineffective. This aim is achieved in that the bearing bodies (3; 4) are, on the sides facing away from the roller axes (22; 23), continued as lever bodies (9; 10) which are assigned shaped pieces (11; 12) mounted in the frame (7). The invention is used in particular in roller grinding machines for grinding pasty and liquid materials. <IMAGE>

Title: Method and device for pollutant analysis in water samples
IPC: G01N21/76
Filed: 1993-09-22
Abstract: A water sample to be analysed is mixed in a mixing vessel (5) with an algae suspension (8) withdrawn from a pure storage vessel (1). After a predetermined reaction time, the mixture is transferred into a measuring cuvette (29) and exposed to weak and modulated measurement light as well as to stronger and unmodulated photosynthetically active continuous light. As a function of the continuous light, the behaviour of the oxygen development of the fluorescence signals emitted by the mixture is detected. The measured values of the fluorescence and of the oxygen development are compared with each other in a computer (33) as a basis for the pollutant analysis. <IMAGE>

Abstract: The subject-matter of the invention is a driving device for a high-voltage discharge lamp, which comprises first and second power supplies 10, 20 for converting a common AC voltage into a DC voltage and outputting the same, a gate driver 30 for outputting first and second gate signals G1, G2 of mutually identical phase and outputting third and fourth gate signals G3, G4 which are of mutually identical phase and of inverse phase with respect to the first and second gate signals, an invertor 40 for generating a positive pulse when the first and second gate signals are output by the gate driver 30, and a negative pulse when the third and fourth gate signals G3, G4 are output by the gate driver one after the other, and outputting the same by using a DC voltage output by the first power supply, and a light-switching block 50 for multiplying the positive and negative pulses input by the invertor to more than tens of thousands of volts.   The driving device can therefore make a high-voltage discharge lamp light up momentarily, as is necessary in the case of internal high-voltage discharge lamps, and also increases the efficiency in that high-voltage pulses are generated both on the positive and on the negative cycle of pulse signals and in that these cycles of high-voltage pulses fed to the high-voltage discharge lamp are shortened.
