Title: Tool changer for multispindle drilling machine - has rotating arm to transfer sets of drills in particular configuration from magazine
Inventor: EWERTOWSKI NORBERT ING GRAD
IPC: B23Q3/157
Filed: 1978-03-16
Abstract: The multiple spindle drilling machine (20) has a set of drills (39) arranged to drill a particular configuration of holes. This set can be quickly exchanged for another set to drill a different configuration by a rotating arm (45) mounted on a column (44) which can slide in a vertical guide (38). A magazine (29) for storing sets of drills is in the form of a rotating platform and brings the required set (55) in line with the arm (45). As the arm rises to receive the drill set (55) it also removes the drill set (39) from the drilling head (21). The arm (45) then rotates through 180 deg. to exchange the drill sets.

Title: Vessel filling system with fluid - feeds already delivered fluid temp. and volume to data processing unit
Inventor: GOUBEAUD MARTIN
IPC: B67C3/00
Filed: 1978-04-13
Abstract: The system fills vessels with fluid using a pressure difference, while monitoring the level in the vessel. The discrepancy of the latter from a desired value within predetermined limits controls the pressure difference. In addition to the measured pressure difference and level, the temperature of the fluid on filling and the volume of the fluid already delivered, sampled at random, are fed to a data processing unit controlling the pressure difference and if necessary the fluid temperature. The empty weight of the vessels can also be sampled at random and fed to the unit.

Title: Time delay release switch - has warmed ferromagnet which loses magnetic properties when on and releases at specified temperature
Inventor: STECKMANN HELGE G
IPC: H01H37/58
Filed: 1979-08-18
Abstract: One/off switch is for electrical equipment only on for a short time period. The switch is held operated magnetically but whilst operated the magnet warms up and loses its magnetic property so that the switch releases. The moving arm (1) of the switch carries a permanent magnet (11) which, when the switch is manually operated (6), closes onto a nickel-iron fixed ferromagnetic contact (4). Operation tensions the moving spring contact (1) which is magnetically held operated. In the operating condition, current heats a resistive component (42) in the circular resistor/ferromagnet structure so that at a certain temperature the ferromagnet loses its magnetic properties and the switch releases due to the spring nature of the moving contact (1). The ferromagnetic regains its magnetic properties on cooling.
