Title: Pneumatic oil level indicator for vehicle IC engine - is worked by hand operated pump to give remote reading
Inventor: TURK ERNST-L
IPC: G01F23/16
Filed: 1975-01-30
Abstract: A pipe (1) dips into the oil sump and is connected to the end of a pump cylinder which contains a main piston (9) with a pilot piston (8) inside it. A hand lever (22) is attached to the pilot piston. A pipe (12) leads to a gauge (4) which has an indicating fluid (7) trapped in a U-bend below a sight glass (5). When the lever is pulled both pistons move to one end of the cylinder. When it is pushed back the pilot piston traps a volume of air in the main piston which is then compressed until it blows all oil out of the dip pipe (1) and at the same time pushes indicating fluid into the sight flass by an amount corresponding to the volume of oil expelled.

Title: Energy conversion system for vehicle propulsion - has a housing, pressure equalisation chamber and a motor for rotating the housing
Inventor: FONTEYNE LEO ING GRAD
IPC: F03G7/10
Filed: 1975-02-27
Abstract: The housing is set in rotation by the motor. The matter in the housing is subjected to centrifugal force and produces a pressure. The pressure equalisation chamber near to the first (A1) of the system's two axles prevents a vacuum being created near to that axle. The power reception body which rotates about the second axle (A2) is exposed on all sides to the pressure of the rotating matter. Due to the off-centre positioning of the power reception body, different pressure zones are created. The power reception body transfers the force (R4) to the axle. The system is suitable for land, water, air or space vehicles.

Title: Air-assisted gyroscopic sorter esp. for mining - has drive unit allowing easy infinite adjustment of fan wheel
Inventor: SIMNOVEC ANDRE DIPL ING
IPC: H02P29/00
Filed: 1975-11-21
Abstract: Wind-tunnel or gyroscopic sorter used in the mining industry has a drive whose shaft (29) of an electric motor (28) is connected to the drive shaft of the pump (30) of an hydrostatic gearing mechanism (31) the motor (33) of which is connected to the shaft of the fan wheel (10) or to the drive shaft (32) of the belt drive (13) which acts on the shaft of the fan wheel. Whilst the speed of rotation of the electric motor (28) is kept constant the amount of hydraulic medium of the hydrostatic gearing at the pump (30) and/or at the hydraulic motor (33) can be regulated in order to control the speed of rotation of the fan wheel (10). The hydrostatic gearing forms a positive connection between the motor and the fan wheel shaft which can thus be set and adjusted because the connection produces reproducible conditions along the regulating stretch.

Title: Large surface area press - has control hydraulic cylinder assemblies between ram and tool holder
Inventor: CHRUBASIK PAUL
IPC: B30B15/28
Filed: 1975-12-30
Abstract: The ram with tool holder is driven by an eccentric mechanism. A pin fitted to the flywheel has a connecting rod acting at the same time as a plunger with hydraulic piston. It is in connection with the hydraulic control system of the press. Between press head and tool holder a number of hydraulic units are fitted and connected to the control system. During the initial stage of operation the rotating crank pin pulls out the plunger from the cylinder creating suction. As the cylinder is in communication with the hydraulic system, hydraulic fluid is withdrawn from the hydraulic cylinders and the pistons together with the tool holder receed.

Title: Self opening stationary thread cutter head - has chasers pivoted sideways after certain length of thread has been cut
Inventor: ROTHAERMEL HELMUT
IPC: B23G5/12
Filed: 1975-12-31
Abstract: The thread cutting arrangement consists of chaser holders (3) which are mounted on pivots (2) in a main body (1).

When the chaser holders reach the end of their travel, they engage with the chamfer and are swung outwards, clearing the workpiece. A slide (28) mounted in the main body is connected to the guide ring (11). Springs are mounted in the main body, and act on the guide ring when the slide pieces (22) no longer overlap with the cam ring.

Title: Filter press water electrolysis cell - with insulating partitions, and conductive through pins for electrodes facing diaphragms
Inventor: PICHLER ALARICH VON DR ING
IPC: C02F1/461
Filed: 1976-01-07
Abstract: The cell is built up of frames and partitions sepd. from each other by diaphragms. The partitions consists of the same electrically insulating material as the frames. Contact bridges (metal pins or strips) pass through the partitions and are connected to electrodes facing the diaphragms. This avoids the corrosion which is inevitable if the partitions are made of iron to act as bipolar electrodes. The cell wt. is reduced and the partition/frame material is stable at elevated temps.

Title: Prolonging aromatisation time of smoking seasoning herbs - for grilling fish or meat over charcoal grill or open fireplace
Inventor: EFFENBERGER WILHELM ING GRAD
IPC: A23B4/044
Filed: 1976-03-23
Abstract: Prolonging of the aromatisation time of smoking seasoning herbs, for grilling fish or meat over a charcoal grill and/or an open fireplace, is carried out by heating or grinding the herbs. They are then mixed and pressed with natural materials e.g., ground hickory, corn flour, beech wood charcoal and/or other suitable materials which have smoking-aromatising properties, in sphere and/or plate form. The time it takes for the spheres and/or plates to become consumed by burning in open embers and/or in an open fire is increased. A fixed length of time for burning and aromatisation is thus obtd., by determining the size and shape of the pressed spheres and/or plates.
