Title: Surgical and positioning and holding needles for mammographic biopsy - has X=ray transmission characteristic differing from that of body tissue to locate lesions when applied to breast
Inventor: LEVENE SIMHA
IPC: A61B10/00
Filed: 1991-02-12
Abstract: X-rays from the source (12) are directed to be transmitted through the breast (16) of the patient. An X-ray receiver (17) is placed opposite the source to intercept the emergent X-rays and form an image of the internal structure of thr breast. A compressor (43,44) holds the breast firm in the direction of X-ray propagation. Two image stores (26,28) hold the mean visual recorded data per image element. A generator (31) excites the source (12) in stages. A differential amplifier (36) and an operational amplifier (37) determine if the latest recorded data for a certain image element matches the mean stored data. A recorder (38) registers these data about the average while anther uses the latest data that differs from these averages for each image element. ADVANTAGE - Rapid localisation using minimal dose of X-ray radiation.

Title: Time-optimising control or regulation of crane-travel gearing or crane trolley carriage drive - reducing angle of deflection of load and its speed at end of acceleration or braking phase necessary for operation
Inventor: WILHARM HEINZ DR ING
IPC: B66C13/06
Filed: 1992-07-17
Abstract: The length of suspension and cycle of swing of the load of the crane or trolley carriage are variable during the operation. The crane-travel gearing or crane trolley carriage drive is controlled at least during the acceleration (T1,T2,T3) and braking (T4,T5,T6) phases according to speed curves (a,b) calculated in advance. These can be arrived at with the help of computer simulation on the basis of installation data, e.g. max. permissible torque and speed, with algorithms independent of load. The control and regulation are advantageously completed by laser monitoring and possibly a positioning as well to counteract risk of danger at high acceleration or speed. The speed curves are radiused and obtain jerk-free transition, possibly by the use of fuzzy logic. ADVANTAGE - Improvement on current practice.
