Title: Automatic motor controlled vehicle speed selector - has contact switches on speedometer with magnet control of carburettor needle
Inventor: KRUMMEL HEINZ
IPC: G01P1/10
Filed: 1974-01-23
Abstract: There is a contact system on the speedometer scale and there is a small wheel which runs along the contacts. This controls, via an electric circuit including a lift magnet, the main jet of the carburettor. The lift magnet moves the carburettor needle. The pressure contacts are in groups of 3 with the individual contacts behind one another. The contact elements overlap one another so that the wheel is in contact with both rows of elements. This provides the electrical output. On electric fuel injection engines there is a separate throttle control rod. This has a latch controlled by the lifting magnet which fits rigidly in the sliding parts of the control rod.

Title: Tower crane crab overload protection equipment - allows two-or four-fall working and lowering when near tower
Inventor: ZERZA HORST ING GRAD
IPC: B66C23/90
Filed: 1974-04-17
Abstract: The equipment incorporates a switching cam moving on the jib in proportion to the crab movement, having one profile representing maximum load for when the crab is close to the tower, and a second one representing maximum tipping moment when it is further from it. A stop switch moved by the hoist rope dependent on the load works in conjunction with the cam. The hoist mechanism can be used for either two- or four-full working, there being a separate stop switch with its corresponding cam profile for each condition. When the crab is on a first part (a) of the jib nearest the tower a locking mechanism for a pair of rope falls allows lowering but when it is on the other part of the jib prevents it. When the crab travels out of the zone nearest the tower and this pair of falls is lowered a changeover mechanism is actuated.
