Patent DE-2443562-A1 (DE)
Title: Oscillographic ferrometer with magnetising device - has step-down transformer and magnetising test channel
Inventor: MOGILEWSKY WITALY MORITSOWITSC
IPC: G01R33/14
Filed: 1974-09-12
Abstract: The magnetising device has at least two identical elliptical solenoids arranged coaxially and with air gaps between them. In the centre of the air gap there is a measuring coil for the magnetising test channel. The current-compensating coil ofthis channel is coaxial with either solenoid. An outgoing and a return conductor connect the solenoids which are connected in the same direction and in series. These conductors form part of the single-turn secondary winding of the step-Down transformer and are designed as a hollow cylinder. They are connected at their ends by collectors, the return conductor being inside the outgoing conductor and coaxial with it.

Title: Check forms for lottery or pools tickets - are pierced for easier checking for winning numbers
Inventor: KELLER WILLI
IPC: A63F3/06
Filed: 1974-09-19
Abstract: The model check form for lottery tickets is made of stiff hardboard bent at one side to provide a convenient setting edge and is printed over with the current lottery form. When the winning numbers are announced the model card is pierced (with a pencil) by the player, at the appropriate plates, to form an inspection window and is then placed over the actual lottery card or pool ticket, to see through the holes, if the winning numbers have been correctly forecast. The model check form once pierced, can be utilised for marking future copies, should the player desire to use the same permutation.

Title: Ignition contact breaker gap adjusted tool - flexible ring has recess for contact breaker heel
Inventor: WENDT HEINZ
IPC: F02P7/063
Filed: 1974-09-23
Abstract: The tool consists of a flexible cylinder of preferably spring steel or similar, with an even wall strength. The cylinder is split vertically down one side and a recess (2) is made diametrically opposite the split. To set the contact breaker gap, the cylinder is placed over the distributor cam and turned until contact breaker heel drops into the recess (2) which simulates the highest lift of the cam lobe.
