Title: Clamped bead tubeless safety tyre - with unequal sidewalls clamped over each other on either side of wheel rim
Inventor: TIEMANN REINHARD DIPL ING
IPC: B60C15/02
Filed: 1973-11-28
Abstract: The tubeless tyre has unequal sidewall diameters and are clamped on either side of a special wheel rim flange. The larger diameter wall is clamped on the outside of the flange by the internal pressure of the tyre while the smaller diameter flange is clamped on the inside of the flange by a special clamping ring bolted to the wheel rim. The clamping ring is sprung so that when fastened it presses the smaller diameter flange tightly against the flange. The system provides a simple safety tyre which is not easily torn off the wheel rim and which requires no special fitting tools, only a spanner, and no great manual effort in fitting.

Title: Beers for different sorts, prepn. - using only two parent brews, only one contg. added hops
Inventor: KLEBER WILLY DR
IPC: C12G3/08
Filed: 1973-12-04
Abstract: Beers of different sorts are produced with only 2 parent brews. Two beers are prepd., opt. different w.r.t. analysis data such as original wort, extract- and alcohol content. One, (A) contains no added hops, and the other (B), contains hops strongly in excess. Only (A) is concentrated to desired extract content, in view of subsequent blending with (B).

Title: Geophysical exploration system - locates and analyses ore-masses by measuring polarisation curves
Inventor: RYSS JURY SAMUILOWICH
IPC: G01V3/04
Filed: 1974-02-06
Abstract: A 3 electrode D.C. system is used, whereby a controlled direct current is injected into the ground at two points, the one being via a multi prong earthing device, at the surface, the other being by means of a bore-hole electrode penetrating the ground. The current is impressed for a predetermined duration, during which period the chemical reaction potential is measured and compared with a nominal value. The output controls the level of impressed current which is monitored and fed to a chart recorder. By this means a polarisation curve is constructed of voltage against current.

Title: Defensive lightweight recoil-less launcher for high shock effect - has projectile with compressed gas carrier for producing required acceleration
Inventor: SELBACH GERD DIPL ING
IPC: F42B5/10
Filed: 1974-04-03
Abstract: The lightweight recoil less small arm with high shock effect is used for protection against armed personal attacks. This small arm with relatively low noise can be used also for protection against predatory fishes under water and also for commando activities. The projectile of great weight receives initial acceleration on initiation and receives further acceleration force by expansion of gases from a pressure chamber after leaving the launcher. The launcher itself does not have to be strong enough to accommodate high pressure. This small arm is readily produced owing to low gas pressures involved.

Title: Slip cast body from alpha calcium sulphate hemihydrate - of controlled particle size range provides hard, crack free ground surface
Inventor: FAESSLE FRITZ
IPC: C04B28/14
Filed: 1974-07-12
Abstract: Slip casting body comprising alpha-calcium sulphate hemihydrate, a liquefier and a set retarder, has at least 50 wt.% of the hemihydrate of particle size range 6-60 mu (20-30 mu). The body further contains 0.2-0.9(0.4-0.6) wt.% K2SO4. Used for making slip cast articles, floor and ground coatings. The slip casting body is fluid and self levelling while producing improved strength without fissuring. Efflorescence does not occur as in prior art since the compsn. does not include free lime. A firm hard surface is obtd. The restriction of particle size range prevents segregation and sedimentation in the slurry, so that a uniform compsn. is poured during casting. The amt. of liquefier used is considerably reduced compared with prior art.

Title: Clutch control valve for speed change gearing - has spring and flow restrictor to determine clutch disengagement time
Inventor: EHRLINGER FRIEDRICH
IPC: F16D67/04
Filed: 1975-08-09
Abstract: The control valve for a hydraulically operated clutch in speed change gearing has a cylindrical valve member axially movable by an actuating piston to open a return flow duct from the clutch. Opening of the member is opposed by a spring and delayed by a restrictor downstream of the valve member.

Title: Valve for bottles containing high pressure industrial gases - has gas chamber which directs gas onto collar sealing rings preventing leak up through spindle
Inventor: ALBERT PETER
IPC: F16K1/30
Filed: 1975-12-06
Abstract: The valve is intended for use with steel bottles containing high pressure industrial gases. The valve head (18) is of square external cross-section and slides in a matching bore (18'). The head (18) is provided with an internal thread (21) which engages the thread on the spindle (7).
