Title: Turbine wheel flow measuring device
Inventor: KOLODZIEJSKI STANISLAW
IPC: G01F1/72
Filed: 1981-04-08
Granted: 1986-09-25
Abstract: The subject matter of the invention is an impeller flow-meter, particularly for accurate measurement of the flow rate of liquid fuel fed to an internal-combustion engine. In the flow-meter according to the invention, an impeller chamber (1) is provided with an inlet pipe (2), surrounded coaxially by an ante-chamber (3). A supply pipe (4) is provided for the liquid fuel and an offtake pipe for excess fuel, these pipes being situated in different planes along the axis of ante-chamber (3). A space (6) is located between the entrance end of inlet pipe (2) and the exit end of supply pipe (4). A slot (7) is formed between the outer wall of inlet pipe (2) and the inner wall of the coaxial ante-chamber (3). The slot (7) communicates with space (6) and offtake pipe (5). As a result of this structure, pulsations in the liquid supply, which would affect the impeller accuracy, are substantially extinguished in space (6) before reaching the impeller chamber (1).

Inventor: FORNSEL HELMUT ING GRAD
IPC: G01R17/06
Filed: 1982-09-14
Granted: 1985-05-23
Abstract: 1. A method of producing a time divider pulse sequence for a follower control device, wherein at regular time intervals (T) a counter (Z) is loaded with a respectively present, digitally-stored measured value (M) and unloaded by a clock pulse sequence, where the ratio of the regular time intervals (T) to the unloading time (T1 ) which is proportional to the measured value, determines the keying ratio (T1 /T) of the time divider pulses, characterised in that the counter (Z) is a count-up/count-down counter and transfer signals which indicate full and empty states of the counter (Z), control a device which introduces the transmission of the digitally stored measured value (M) into the counter (Z), and control the setting input of a flip-flop (FF) which serves as a store for the counting direction and at whose mutually inverse outputs a counting direction signal is tapped for the control of the counter input or the time divider pulse sequence, as the case may be.

Filed: 1983-12-22
Granted: 1989-07-06
Abstract: A plurality of scanning regions (22) are disposed about the anticipated region of a phase boundary (32) of two media. The change in position of the phase boundary (32) is detected by a scanning means (18) with which each scanning region (22) is scanned and a signal is generated for each of the scanning regions (22). The first media is more radiation-permeable than the second media. A beam path is generated by the scanning means and is detected and evaluated by a discriminator circuit as a logic one. The second media is less radiation-permeable than the first media. The absence of a beam path corresponding to scanning regions in the second media is evaluated by the discriminator circuit as a logic zero. The number of signals per measuring cycle is compared against the actual number of scanning regions (22) to locate and control the position of the phase boundary (32).

Title: Revolving storage rack
Inventor: SCHMITZ JOACHIM DIPL ING
IPC: B65G1/00
Filed: 1986-01-31
Granted: 1988-05-11
Abstract: The present invention provides a circulating rack having an electric drive which can be pivoted, to a limited degree, in opposed directions dependent upon the transmitted torque of the electric drive. The drive is mounted on a pivotal rocker element which is displaced against the force of two counteracting elastically deformable abutments. A torque transmitted by the electric drive to overcome non-uniform loading of the circulating rack system causes the pivotal rocker to be displaced in either a clockwise or counterclockwise direction. A displacement measuring sensor measures the extent of pivotal movement of the rocker to provide an indication of the non-uniform loading condition so that corrective action may be taken. If the rocker is pivoted beyond a predetermined range, as for example that caused by a severe overloading condition, the displacement measuring sensor will cause the electric drive to turn off and prevent further circulation of the system until the overload has been corrected.

Title: Cutting tool
Inventor: ALTMEYER WERNER
IPC: B23B27/14
Filed: 1986-07-22
Granted: 1989-07-06
Abstract: A material removing tool wherein a substantially plate-like support of steel carries at least one annular cutter which is made of a harder metallic material capable of being soldered to the material of the support. The support has a centrally extending projection which is received in a complementary opening of the cutter, and the cutter has two or more substantially radially extending webs in register with grooves which weaken the cutter in the regions of the webs so that at least one of the webs breaks in response to soldering of the cutter to the support. The breaking of one or more webs is promoted by proper selection of the thermal expansion coefficients of the materials of the support and cutter. The provision of breaks in the webs, either as a result of bonding or as a result of utilization of cutter sections, ensures that each cutter section between two neighboring webs can be put to use independently of the condition of the other section or sections.
