Title: Linear motor for display and recording instruments - has permanent magnets movable over separate paths between stationary excitation coil and yokes
Inventor: HONDS LEO
IPC: G01D5/12
Filed: 1976-01-31
Abstract: The linear motor for display and recording instruments has at least one stator core, an induction coil and outer magnetic piece to complete the magnetic field path. Magnetised permanent magnets are provided between the latter yoke piece(s) and the coil at right angles to the coil axis. Permanent magnets (11a,11b) movable over separate paths between the stationary excitation coil (5) and the yoke (7) are so magnetised, that when the coil (5) is energised, they move in opposite directions. The magnets are interconnected by a reversing connection (13b,15). This arrangement ensures that disturbances result in the smallest possible amount of diversion of position of the rotor.

Title: Pulse wave indication equipment - detects fluctuations electronically above and below radius bone and produces visible or audible signals by oscillating mask
Inventor: DUERR HANS
IPC: A61B5/024
Filed: 1976-03-16
Abstract: The equipment gives an optical and/or acoustic indication of pulse wave fluctuations due to auricula-cardiac reflexes. The waves are electronically detected at two or more points above and below the radius bone, being converted to electrical impulses which are made optically or acoustically detectable. Conversion can be by the regulation of a beam or light directed onto a photoelectric cell, typically using a mask oscillating in synchronism with the waves. Alternatively, the beam of light can be conducted by one or more light-conductive fibres made to move by the waves, and thus controlling the amount of light striking the cell.
