Patent DE-4130591-A1 (DE)
Title: Handpiece for optical fibre changeover in medical laser - couples fibres selectively by direct connection to laser beam supplying fibre so that proximal ends of fibres can be exchanged via guide plugs and held by springs
Inventor: LIEBETRUTH JOCHEN DR ING
IPC: A61B18/22
Filed: 1991-09-12
Abstract: A compression spring (10) holds the optical fibre (8) in the respective guide position. The fibres to be used (8) are secured respectively by a clip (7). A tension spring (9) is also provided in the guide body (4). The handpiece is cylindrically shaped and is divided in to an upper part (1) and a lower part (2). Both can be rotated against each other and pushed. A suitable known guide system in the upper and lower parts prevents a twisting of the application fibres. The change of the application fibres (8) in the handpiece is performed by a counter rotation or a push movement of the upper and lower parts (1, 2). So that the fibres move counter axially. USE/ADVANTAGE - For cutting or tissue separation. Disadvantage of using single fibre optic with lens coupling for alternative duties is eliminated. Change of in contact and non contact techniques is possible using selected fibre, so that cutting and effective coagulation are facilitated.

Patent DE-4135834-A1 (DE)
IPC: G11B15/675
Filed: 1991-10-30
Abstract: It is known, especially in ordinary commercial video recorders, to use a cassette loading device with a cassette acceptance device. It is also known to lock cassettes of a given system standard by means of an engagement block engaging in a recess in the side of the casing of such a cassette away from the drive during the loading or unloading procedure. The aim of the invention is to provide a cassette lock which is not bound to a system standard. Instead of positioning pins arranged on the mechanism chassis (7) for centring a cassette (1) there are corresponding centring apertures (7a; 7b) in the chassis and pivotable positioning pins (111a; 111b) on the cassette acceptance device (10) which co-operate with the cassette loading device in such a way that, when a cassette (1) is inserted into the acceptance device (10), these pins (111a; 111b) pivot into acceptance apertures (6e; 6f) in the cassette (1), remain in engagement therewith during the loading process and, when the cassette has reached the operating position, engage with the centring apertures (7a; 7b).

Title: Measuring sensor parameter-dependent impedance change e.g. for inductive path sensor - using calibration mode, in which start time is measured, after which signal reaches measurement region, and converting each signal to digital value when value at start of measurement region is exceeded.
Inventor: KARES WALTER
IPC: G01D5/00
Filed: 1992-05-13
Abstract: After a start time defined by an input pulse, the signal is passed through the measurement region at a speed dependent on the physical parameter. In a calibration mode using a value for the parameter corresp. to the start of the measurement region, the time is measured after the signal reaches the start of the region. Each value of the signal by which the value at the start of the measurement region after the time measured during calibration is exceeded is digitised for measurement of the physical parameter. USE/ADVANTAGE - E.g. for coil-core position dependent sensor for measuring displacement. High accuracy is achieved with high digitisation resolution at minimal cost. Uses whole range of A-D converter for higher resolution and reduces offset error of measurement circuit, amplification error, influence of supply voltage and variation of coil resistance.

Title: Damping pendulum movement of hanging loads on crane - using microprocessor to control crane movement and load cable length using sensor input of cable angular velocity and acceleration
Inventor: HINUEBER EDGAR VON DIPL ING
IPC: B66C13/06
Filed: 1992-11-17
Abstract: The movement of load attached to a crane by a cable will incur pendulum movement from various external causes e.g. wind load which can normally be handled only by an experienced crane driver if accidents are to be avoided. If angular velocity and acceleration sensors are incorporated in the crane to record the movement of the load cable, then a microprocessor can be used to control the cable length and crane movement in order to damp out the pendulum oscillations. The principle can be applied to the operation of any material-handling system with hanging loads. ADVANTAGE - Allows the use of unskilled personnel without endangering safety.

Patent DE-4244732-A1 (DE)
Title: Method of controlling a rope-driven hoist
Inventor: SCHULTE-LANDWEHR HELMUT
IPC: B66C13/46
Filed: 1992-12-09
Abstract: Hoists of this type typically have a motor-driven rope pulley. Deflection pulleys and/or pulley blocks to which the load is fastened are additionally arranged. The motor-driven rope pulley is often controlled visually. Approaching desired positions at the load on the travel way cannot therefore take place sufficiently accurately or safely. According to the invention, a measuring device is arranged on the motor-driven rope pulley. The position of the load on the travel way is recorded and the rotational-speed-dependent braking distance is determined by this measuring device. With these data, any established position at the travel way of the load can be approached automatically and reliably while allowing for the braking distance.

Title: Automatic transmission with electromagnetically braked planetary gear - smooths transmission of power from input to output shaft by gradual retardation of planet wheel rotation
Inventor: ICHIZUKA TETSUYA
IPC: F16H61/02
Filed: 1993-01-13
Abstract: To achieve entirely continuous power transmission one planetary gear (20) is associated with a brake (22) for redn. or gradual slowing of the movement of the planet wheels in accordance with the rotational speed (12) of the output shaft (10).

The control responds to a throttle switch (29) and sensors of throttle flap position (30) and engine compression (31). Signals from a speedometer, an engine load sensor (31) and a throttle setting sensor (30) are delivered to the control (28). Based on these input signals, the latter generates a control signal for switching a magnetic switch (16) on or off. ADVANTAGE - Output shaft speed changes are continuous and smooth, and drive is transmitted with min. loss.
