Title: Passive base for thick or thin film structures - has rounded edges for overlap of film layer and metallised side contacts
Inventor: HORSTMANN HANS-WOLFRAM
IPC: H05K3/40
Filed: 1979-07-07
Abstract: The passive base element is for thick or thin film techniques. The film layer follows the curved edge of the ceramic base material to form a stable connection with the metallised ohmic side contacts. The film to contact junction withstands prolonged temperature and vibration life tests. The thin or thick film resistance layer (66) is deposited by a high vacuum evaporation process on the curved edge ceramic base (55). The metallised contact edges (77) of solder compatible material are also deposited by high vacuum evaporation techniques or by a dip method. The curves' radii (88) at the edges have an overlap of materials and are at least twice the thickness of the ohmic (77) layer. Typically the ceramic (55) will be 3.2mm long by 1.6mm wide by 0.6mm thick with an edge radius of 0.2mm. The resistance layer (66) is typically 10 micrometer thick and the edge metallisation, possibly silver, is also 10 micrometer.

Title: High pressure measurement of viscous liquids in small containers - using membrane and compensation pressure generated in vaporiser with electrical heating
Inventor: ROEVER MARTIN DR ING
IPC: G01L11/00
Filed: 1980-02-18
Abstract: A small pressure transfer membrane (1) is used for measurement of high pressure in narrow conductors and small containers, esp. for viscous media. A compensation pressure is automatically generated in a liq. evaporator of very small vol. and large cooling surface. The compensation measurement is combined with generation of the compensation pressure by evaporation of the liq. using electrical heating automatically controlled according to the flexing of the pressure transfer membrane. The heating occurs in a thin-walled specially shaped metal capillary tube of large surface area and small vol. whose walls act as a thermal conductor. The tube is a spiral (14) whose high flow resistance clamps out pressure fluctuations caused by on-off heater regulation.

Title: Ultrasonic transducer measuring displacement of moving parts - uses additional receiver for transmission fluid characteristic variation compensation
Inventor: BURNAND PETER WILLIAM
IPC: G01B17/00
Filed: 1980-02-19
Abstract: An ultrasonic transducer for indicating linear displacement between parts moving relative to each other has a cylinder contg. a quantity of fluid and a piston moving w.r.t. the piston. The transmission path between an ultrasonic transmitter and receiver in the fluid is parallel to the direction of relative motion of piston and cylinder. The errors in length measurement due to the variations in modulus of compression and density of the fluid are compensated for by using a second ultrasonic transmission path in the fluid of constant length or of partially constant length. This is achieved by placing the transmitter (8) on the cylinder wall (2) and the receiver (9) on the piston (4) with an additional receiver (10) mounted on the piston a known distance further from the transmitter than the first receiver.

Title: Time measuring system between timing signals - uses extraction of measured values of oscillations from free-running quartz oscillator
Inventor: CHABORSKI HOIKO DIPL ING
IPC: G04F10/04
Filed: 1980-03-28
Abstract: The time measuring system measures the time between two time making signals by summing a series of oscillation periods of a free running oscillator to obtain a coarse measured value and obtains an analogue value for a fine measured value. The count obtained from the first time marking signal from a series of signals is continued, and a second marking signal is read and stored. To obtain the coarse measured value, the value obtained from the two marking signals is subtracted from the second value obtained by the counting system. The free running oscillator is quartz controlled. The analog measurements for obtaining the fine values are obtained by time/amplitude conversion circuits. After triggering by a start signal an output is obtained which constantly increases in amplitude to give a measure of the time following the start signal.

Title: Guide-cam drive for two operating devices
Inventor: ENGERTJ HEINZ-DIETER
IPC: G01F11/00
Filed: 1981-02-06
Abstract: A guide-cam drive for two operating devices is proposed. The operating devices, actuated via a linearly movable plunger, each work with a stroke and return stroke, and a motor running in one direction of rotation and a cam plate driven by the motor are provided. The cam plate has an outer profile from which the drive for the first operating device is taken. A lever provided with an inner cam profile is pivotably mounted next to the cam plate. The drive for the second operating device is taken from this lever. Such a guide drive ensures that merely a single drive motor is required and both operating devices work exactly in synchronism. The drive for the operating devices can be used in particular in a device for the metered delivery of liquids with a pump which during each pump stroke delivers a metered quantity via a pipette which is in turn pivoted and lowered during each operating cycle and finally returned again. <IMAGE>
