Title: Hydraulic linear drive mechanism - has valve protruding into piston recess opened and shut by fluid pressure
Inventor: KIMURA KIYOSHI
IPC: B25F5/00
Filed: 1991-04-17
Abstract: The hydraulic linear drive mechanism has a piston (38) sliding in a housing (16) and enclosing a fluid chamber (40).  A recess in the piston is connected by a passage (68) to the chamber, while the outlet (54) from the latter is in the housing end (18), and is opened and shut by a valve mechanism (52) protruding from the chamber into the piston recess. The passage in the piston delivers fluid under pressure into the piston recess as the piston moves away from the housing end under fluid pressure, so as to hold the valve head (62) shut by fluid pressure. The maximum diameter of the passage is less than that of the valve head.  Thus at or near the end of the piston stroke in this direction incoming fluid pressure acts on the valve head, causing the non-return valve mechanism to open the outlet. ADVANTAGE - Simplicity and faster valve operation, being particularly for a portable tool cutting reinforcing rods etc.

Title: Microwave contactless distance measurer with circulator and second mixer - interprets phase difference between transmission and received echo using cosine-shaped distance relationship of output voltage
Inventor: LINDNER KURT DIPL ING
IPC: G01S13/36
Filed: 1991-05-25
Abstract: Energy from the generator (40) is transmitted through the circulator (30) and attenuator (20) to an antenna (10) which also receives the reflection from the object (33) at a distance of typically a few millimetres. The reflected energy passes through the circulator (30) to the second mixer (50) whose output is filtered (60) for further processing. 10 to 20 dB attenuation (D) prevents resynchronisation of the generator (40) by echo signals and overdrive of the mixer (50), which may be duplicated for quadrature outputs. USE/ADVANTAGE - In motor vehicles, fabrication plants or consumer electronics, very small movements can be measured with high precision and reliability.

Title: Measuring turbidity and mass flow of suspended particles in liquids simultaneously - regulating diode emission power, averaging turbidity over repeated cycles and measuring transition time of flow rate
IPC: G01F1/7086
Filed: 1991-12-04
Abstract: The method involves measuring the turbidity during a measurement cycle from the constant light equivalent voltage on a photoreceiver (9). The emitted power from a light emitting diode (4) is adjusted (10) to achieve a constant photoreceiver voltage independent of the turbidity. The turbidity is averaged over 10 measurement cycles and correlated (11) with a standard to produce a value in turbidity units. A flow rate measurement is performed using separate optical fibres and photoreceivers and a time measurement method. The diodes and photoreceivers are mounted in a temp. regulated heat conducting adapter (14). The errors caused by turbulence between the fibres are compensated by a computer (11). ADVANTAGE - Enables simultaneous measurement of turbidity of particles suspended in liquid and of mass flow independent of turbidity.
