Title: Wheel spin limiter for car - with variable brake force for either driven wheel by compensating lever
Inventor: OTTO ARNOLD DIPL ING
IPC: B60T7/10
Filed: 1973-12-18
Abstract: Unequal wheel spin on cars can be prevented using an expensive, complicated limited slip differential. The invention provides a simple manual control for limiting slip. The handbrake lever is coupled to the two rear wheels by separate cable drives each of which is fitted to a pivotted lever which can be moved sideways to slip off the handbrake lever. This disengages the handbrake on one wheel and enables the driver to lock, or partially lock the other wheel. For vehicles in which the parking brake does not act on the driving wheels some simple form of differential brake control, operated manually, can be provided for the driven axle. The driver has full control over the traction if his vehicle is stuck.

Title: Monitoring of rotational oscillations of drive gears in ships - involves deviation of pulses and storing pulse minima and maxima
Inventor: PINNEKAMP WOLFGANG DR ING
IPC: G01H17/00
Filed: 1974-10-12
Abstract: The apparatus detects incipient failure of a cylinder in a ships diesel engine as loss of power in one cylinder causes increased torsional oscillations. The measurement is achieved by the derivation, in known manner, of an impulse series indicative of the tooth strain in a gear wheel. Such derived indications for the root of the teeth have been utilised for supervising maximum and minimum values and from their differences evaluation has been made of the rotational oscillation, but this has not been amenable to electronic control. In the present case, during a measuring period, the respective maximum and minimum deviating from zero pulses of the series are stored and compared with one another. With their difference exceeding a predetermined amount a signal is produced as an alarm. A maximum store, minimum store and subtractor stage are incorporated.

Title: Scattering effect reducing system for X-ray tubes - has grid between source and recorder to suppress lower frequencies
Inventor: KOWALSKI GUENTER DR
IPC: H04N5/32
Filed: 1974-11-16
Abstract: The scattering-reducing system, for X-ray tubes, has a periodic grid (G) placed between the source (Q) and the recording unit. the lower local frequencies picked up by the grid of the object's image are suppressed. The image information modulated by the grid is then demodulated. The lower frequencies are suppressed by recording a first image, then shifting the grid by half its grid constant to take a second recording. The two recorded images are then subtracted from one another. The scattering is thereby suppressed while the image information is still kept.
