Title: Seismograph for determining subterraneous stratification - produces shock waves in several rows for reflection and reception by detectors
Inventor: DAVIS JLEE
IPC: G01V1/36

Patent DE-2406637-A1 (DE)
Title: Flagstone grinding and polishing machine - has height regulating feelers for stones of uneven thickness
IPC: B24B7/22
Filed: 1974-02-12
Abstract: The flagstones travel in relation to the machine, which is equipped with a flat grinding plate on articulated mountings. Where the stones have irregular shapes or thickness, variable-height feelers control switches regulating the upward and downward movement of the grinding plate, and if necessary of its mountings also. Entry of a stone into the machine can be arranged to cause lowering of the grinding plate and exit its raising, and the mountings can be moved each time the grinding equipment risks running off the edge of the stone.

Title: Vertically stabilised rigid rear axle - is braced by trailing struts and by diagonal struts leading to strong chassis points
Inventor: ZILLNER GUENTER
IPC: B60G9/00
Filed: 1974-04-01
Abstract: The rigid axle is supported on two sets of trailing arms on each side of the vehicle, and on coil springs from the chassis. Lateral stability is by means of diagonal struts mounted between the ends of the rigid axle and a middle point on the chassis, forward of the axle. The middle mounting point is fitted with elastic bearings. The system is light and compact and prevents the rear wheels from being displaced laterally during suspension movement. The sprung mass of the rear axle is also kept to a minimum for increased control.

Title: Pre-selector for counter allows even number selection - by choosing next highest or lowest numbers if selected number lies outside range
Inventor: MUELLER RICHARD
IPC: H03K23/66
Filed: 1974-09-23
Abstract: The pre-selector, for a counter, has a count pulse (AI) passed to the counter input when an even number is selected. With a backwards counter the next highest count is automatically selected; whilst with a forwards counter the next lowest count is automatically selected if the pre-selected number belongs to a group that cannot be selected for the counter. The count pulse is only passed to the input of the counter when the counter contents correspond to the stored count; the memory holding the count pulses is then cleared. The keyboard has two groups of contacts located side by side.

Title: Radioactive effluent esp. sewage is decontaminated by decay - through successive stages with thorough mixing to equalise dwell times
IPC: G21F9/22
Filed: 1974-12-21
Abstract: A method of decay-decontamination of radioactive sewage or other effluent consists of passing the effluent, after clarification, through (on the once-through principle) a series of several mixing stages which determine the dwell time behaviour. More specifically, it is passed alternately through pipes and relatively wide tanks, and is agitated and mixed in the tanks e.g. by blowing in air. Esp. for treating toilet effluent from hospitals where nuclear medicine is practised. The method enables the dwell time to be kept the same for all parts of the flow, and to be increased or decreased to suit requirements.

Title: Windscreen wipers for motor vehicles - has detachable wiper arm held over bush on drive spindle by spring retainer
Inventor: LUNETTA SAVERIO
IPC: B60S1/34
Filed: 1974-12-21
Abstract: The wiper overcomes the difficulty that wiper arms cannot normally be detached from the wiper spindle. This is not inconvenient for hand cleaning and can cause damage to the spindle if the balde becomes trapped during operation. There is a sleeve fitted on the driven end of the wiper arm. This is held by a spring loaded retainer that can only move along the spindle. The retainer (22) has a separate locking element (30). The spring plates (22) are at an acute angle to the spindle axis and the rear end is held in a shoulder (25) in the sleeve (16). A cap (33) fits over the retainer (22) and the locking element can be desinged as part of the cap.
