Patent DE-2353459-A1 (DE)
Title: Optical vehicle wheel tracking system - allows simultaneous independent alignment of both wheels on axle
Inventor: HOLSTEIN WERNER
IPC: G01B11/275
Filed: 1973-10-25
Abstract: A light beam projector mounted on each wheel on the same axle projects a beam onto a scale fixed to the other wheel. The two projectors are fixed to their respective wheels in such a way that when the wheels are aligned parallel to each other each beam impinges on a zero mark on the corresponding scale. The scales may be provided with a light reflecting surface and an anti-glare cover. The projectors and scales may be fixed to plates attached to the brake drums. The misalignment of the wheel track is generally never greater than 5 deg. so that a turning of the scale through such an angle will not effect the measurement result.

Title: Control system for I.C. engine starter - keeps starter pinion engaged until minimum engine speed is reached
Inventor: KLEIN ERWIN DR ING
IPC: F02N11/08
Filed: 1974-02-18
Abstract: The solenoid which engages the starter pinion also operates a switch which connects the power source to a tapping point on the ignition coil. The tapping point is also connected through the resistance to the control. The terminal on the control box is connected to the terminal of hte ignition coil and to the condenser. The control box contains an electronic circuit which maintains the current oscillations in the circuit in synchronisation with the interruptor, with the effect that the solenoid remains energised until a minimum engine speed has been reached. This eliminates false starts and the passage of unburnt fuel into the exhaust.

Title: Reproducible doping of (silicon monocrystal) semiconductor rod - by incorporating dopant in surface layer and non-crucible zone melting
Inventor: BURTSCHER JOACHIM DIPL ING DR
IPC: H01L21/225
Filed: 1974-04-01
Abstract: Doping of a semiconductor rod, esp. a Si monocrystal rod in the required and reproducible manner, is achieved by non-crucible zone melting, with the rod in the vertical position, by incorporating the dopant in the surface layer of the rod corresp. to a programme determined by the required dopant concn. and then distributing the dopant evenly over the cross-section of the rod by zone melting, using the surface layer as dopant source. The dopant can be incorporated in the surface layer by ion implantation or by diffusion, using a molten or gaseous dopant. The required dopant concn. can be obtd. reproducibly and can be varied along the rod. The process is suitable for use with various dopants.

Title: Mash saccharification indication - by reflectometer comparison on mash surface before and after addn of lugol's soln
Inventor: BISCHOF PETER
IPC: G01N21/47
Filed: 1974-04-08
Abstract: The saccharification of mash in a beer brewing process can be supervised by optical observation of the colour change of a mash sample to which Lugol's soln. has been added. An optoelectronic reflectometer measures the intensity of the radiation from a stabilised light source which has been reflected in the characteristic blue range at the surface of the mash sample. A difference amplifier compares the result with that of a second reflectometer on an untreated mash sample. This simple measuring set up functions reliably under the rough conditions in a brewing house. It produces quick results and can easily be automated.

Title: Magnetic load lifter without slinging operation - has permanent magnet with rotating actuating block and pole pieces
Inventor: BAAR JIRI DIPL ING
IPC: B23Q3/154
Filed: 1974-05-14
Abstract: The load lifting magnet active lifting force is adjusted by an auxiliary magnetic field of an adjusting block. The ferromagnetic material is lifted with reliable and adjustable lifting force. The load is lifted by the block (1) and this block is controlled by adjusting block (5). Both blocks have a number of permanent magnets. The adjusting block is arranged above the lifting block and its poles have opposite polarity. The distance of the adjusting block can be varied in relation to the main lifting block. On short circuiting the blocks, i.e. when both blocks are connected, the lifting force is zero. The lifting force is increased by increasing the gap between the blocks. The adjusting block is rotated about an eccentric axis (8) for gap adjustment.
