IPC: F16L3/10
Filed: 1974-01-30
Abstract: The device for fixing cables and pipes, mounted on walls, ceilings or floors, has a bottom-part that can be fixed on the particular base and a top-part that can be placed on the bottom-part and mechanically interact with it.

Title: Process for soldering miniature components to boards - has blobs of solder on boards contact pads re-melted to link with component
Inventor: HOHMANN ROLF
IPC: H05K1/09
Filed: 1974-03-07
Abstract: The soldering process allows miniature electronic components to be soldered to circuit boards or base plates. The board or plate has contact pads with conducting paths formed on its top surface. The contact pads are tinned and a blob of solder formed over each of them which links with the electronic component. The contact pads may have comb-like structures -- in which case each tooth of the comb has its own blob of solder. This soldering method allows the component to be positioned precisely before final fixing by re-heating the solder blobs until they fuse with the contacts of the component.

Title: Hydraulic crane electronic control system - releases hoist brake only when sufficient torque is exerted via converter
Inventor: LAYH HANS DIETER
IPC: B66C13/22
Filed: 1974-08-01
Abstract: The crane hoist brake is controlled that it can only be released when the hydraulic torque converter (6) between the motor (7) and the winch (1) has fully built up the torque necessary to counteract that exerted by the load.
