Patent DE-2842450-A1 (DE)
Inventor: CHABORSKI HOIKO DIPL ING
IPC: G04F10/00
Filed: 1978-09-29
Abstract: A time duration is measured precisely and with high resolution by making three time measurements as shown in FIG. 5. The time difference tA between the leading edge of a start signal and the next following leading edge of a constant frequency time base signal is measured. The number "n" of the following leading edges is then counted including the leading edge of the time base signal following a stop signal. The number n is multiplied by the period TQ of the time signal. The time difference tE between the leading edge of the stop signal and the next following leading edge of the time base signal is measured. The real time difference  DELTA t is then calculated as follows  DELTA t=tA+nxTQ-tE. A three part real time measurement is performed to correct the calculated result for drift and aging. Calibration measurements are made and the respective calibration factors are used in calculating the final results. The respective circuit arrangement includes a start channel, a stop channel, and the corresponding supporting circuits.

Title: Measuring system to hardness tester impressions - uses transparent ball as impression member, through whose centre the impinging light beam is passed
Inventor: KLEESATTEL CLAUS DR
IPC: G01B11/02
Filed: 1978-11-07
Abstract: a focussed light beam is directed through the impression element onto the tested surface during the effect of the testing force in a plane orthogonal to the tested surface and through the centre of the testing impression. The light beam diameter is small as compared with the diameter of this impression. The beam is moved in this plane, as to pass over the centre point of the tested impression. The changes in light reflection provide the measure of the impression, as in 2803149. The impression element is in the form of a ball of transparent material, and the impinging light beam is passed through the ball centre point. The light beam movement swings about an axis parallel to the tested surface and passing through the ball centre point. This determines the intensity of the light reflected in the impingement direction. The angle of swivel between two successive intensity changes is measured. Preferably infra-red light is used for this measuring system.

Title: Fuel-air mix control system for IC engine - closes exhaust-gas return line and sets fuel-quantity to zero to prevent wrong setting on starting
Inventor: STUMPP GEORG
IPC: F02M26/21
Filed: 1979-05-02
Abstract: The control system has the inlet hole of the outflow line (43) controlled by the member (39) separating a first pressure chamber (37) from a second pressure chamber (38) such that as the pressure drop increases the cross sectional area of the hole is also reduced. The two chambers belong to a throttle valve. A fuel metering device (7) coupled to the setting element of a setting motor (9) moves in the direction of smallest fuel quantity when the setting element is displaced under the action of its restoring force. The setting element is therefore set such that the exhaust gas return line is closed in one type of control and the fuel-quantity controller is set to zero quantity in the other type of control.

Title: Metallurgical vessel, esp. steelworks converter - where vessel barrel is periodically rotated through an arc to minimise distortion
Inventor: JANSA WOLFGANG
IPC: C21C5/50
Filed: 1979-09-15
Abstract: The vessel, esp. a converter barrel is located in a carrier ring provided with a pair of trunnions so the barrel can be tilted through 0-360 deg. Mechanical devices are also provided for turning barrel through a fixed angle of e.g. 90deg. in the ring. The mechanical devices include two guide tracks (29) located diametrically opposite each other on the underside of the ring. When the barrel is turned upside down, work cylinders are used to lift the barrel so rollers can be placed on tracks; and the barrel is lowered onto rollers. A cable winch can then rotate the barrel through 90 deg. in the ring. Due to the high mechanical and thermal stresses, the barrel distorts to an oval shape when tilted. The invention permits the periodic rotation of the barrel, thus increasing its working life.

Abstract: The tank (1) has a flow channel (4) communicating with the top and bottom of the tank (1) and containing the immersion heater (6). A temp. sensor (12) depends vertically into the tank itself to monitor the water temp. at various levels. The sensor causes the immersion heater (6) to be switched OFF when the water temp. reaches a specific level (H1,H2) corresponding to a given quantity of water selected via a switch (11). A circulation pump (5) is incorporated in the flow channel (4) for feeding water from the bottom to the top of the tank via the heater (6). It is electrically connected in parallel with the heater (6) both being connected to the supply via one of three parallel switch contacts (8,9,10) controlled by the temp. sensor (12). Each is associated with one position of the selection switch (11).

Title: Pulse frequency divider - has variable frequency and ion jitter level achieved using multiplier and flip=flop dividing chain
Inventor: METTLER HELMUT DIPL ING
IPC: H03K23/66
Filed: 1980-03-27
Abstract: The frequency divider has a pulse rate multiplier coupled at the output to a divider comprising a chain of flipflops. Whenever the selected frequency of the output pulse sequence drops below a power of two, a flip flop stage is disconnected from the multiplier (2) and a flip flop stage is connected into the flip flop chain (4). Logic gates are used to switch out stages in the multiplier. Switch-out signals for stages in the multiplier are passed to the gates and simultaneously cause flip flop stages to be switched into the flip flop chain. The circuit reduces jitter at low output frequencies.

Title: Light fitting with spherical or cylindrical light source - has specified reflector elements with given angular dimensions, related to light source reflection
Inventor: PRICE EDISON
IPC: F21S8/02
Filed: 1980-04-15
Abstract: The light source of the reflection light fitting has a radiating surface at least partly spherical, or cylindrical with a horizontal axis. The reflector has elements directing the light in preferred directions. The vertical section plane of each element is aligned relative to the coordinate axes. Each reflector element defines an upper reflector edge, as well as a lower reflector edge at a light outlet aperture. When viewed against the vertical Y-axis it suppresses any reflection above an upper radiation angle. Both coordinate axes are defined by equations, relating to the radius of the light source at a tangential contact point, to the upper radiation angle, and to a variable angle between the X-axis and the light source radius. Each reflector element is defined by specified coordinates, related to angular conditions to the upper reflector edge.
