Patent DE-2124172-A1 (DE)
Title: Casting plastic sieve - using mould assembled from frame and core components
IPC: B29C33/16
Filed: 1971-05-15
Abstract: A method of making a rubber, elastomer or plastomer sieve, opt. with reinforcement, by mould casting uses a mould bottom with attached projections to form the holes in the sieve. When making a reinforced sieve, the reinforcement itself constitute an integral part of the mould bottom; when making an unreinforced sieve a reusable element such as sieve plate, mask, template or a supporting plate is used for the sieve bottom. In a prefd. arrangement, the individual projections used for forming each hole in the sieve, and also the end and side frame members, have iron cores and are mounted on a magnetic plate as the permenant bottom of the sieve with a non-stick sheet between them.

Title: Bottle moulding machine - has horizontal injection and vertical blowing positions
Inventor: AOKI KATASHI
IPC: B29C37/00
Filed: 1972-09-28
Abstract: An injection parisons and then bottles, comprises a e.g. for forming parisons and then bottles, comprises a revolving support for the mould cores; the cores are fitted to vertical and horizontal faces respectively of the support, which rotates about an axis bisecting the angle between them, i.e. at 45 degrees to the horizontal, so that a 180 degrees rotation of the support interchanges the positions of the cores; a horizontal sliding mechanism advances and withdraws the support in relation to a fixed metal mould for forming the parison on one core, while a blow mould of metal receives the vertical core, together with the parison mounted on it; hydraulic equipment closes, opens and clamps the mould. An injection moulding machine has its nozzle projecting into the parison mould. This enables the injecting operation to be carried out in the horizontal, or most convenient position, whereas the parison is then turned vertical to prevent its walls becoming uneven in thickness.

Title: Ring turbine homogeniser - having 2 or more independent ring motors driving circular shear elements
Inventor: STELZER ERWIN
IPC: B01F7/16
Filed: 1973-08-25
Abstract: Ring turbine homogeniser has two or more turbine discs driven by independent ring motors mounted horizontally one above the other in a housing on flange. Rotor coils are bearing mounted onto the housing and are directly coupled to concentric hollow shafts. There is an extremely narrow air gap. At the other end of the shafts are the conical shaped shearing elements. These are of geometrical similar shape so that a constant gap is maintained during rotation. The motors being independent can be driven in reverse direction so the central shaft can be driven in the reverse direction the the others. The mixing elements have uniform slots or similar in them through which the material must flow and thus be subjected to a shearing action and consequent mixing. At least one of the discs must be adjustable in the axial direction. Used for all mixing/homogenising applications. Much more flexible and quiet to run then normal drives where a single motor is used. Changes in the mixing action are simply and rapidly made without having to take machine out of commission.

Title: Gas filter with backflushing of bags - by travelling head with blower and motor mounted on it
Inventor: HUTTEN FRIEDRICH KARL FRHR VON
IPC: B01D46/00
Filed: 1973-09-13
Abstract: The Parent Paten describes a cleaning mechanism for air or gas bag filters, where each of the filter bags has its internal, clean side discharging through a slit into a common vacuum chamber; in this chamber, a moving head which visits each slit in turn supplies pressurised air into the slits thus backflushing each bag in turn; the air supply pipe to the pressure head is aligned with the direction of movement of the head, thus passing through a small opening in the end of the vacuum chamber; the blower travels with the head and, in a preferred embodiment of this arrangement, is mounted on the head i.e., inside the vacuum chamber, the motor, however remaining outside. This arrangement requires only a small opening for the pipe and opt. for the drive shaft, and is the pref. embodiment enables the back-flushing air to be drawn directly from the interior of the vacuum chamber. In the Patent of Addition, the motor is mounted in addition to the blower directly on the head the moving pipe thus being on the suction side of the blower. The moving pipe does not carry any superfluous weight e.g. motor, all these weights being mounts on the relatively robust and well supported blowing head. The pipe can also be used as a push or pull rod for moving the whole mechanism.

Title: Helicopter-type water craft - has rotating angled propellers to raise it out of the water and provide forward thrust
Inventor: HALLER ERNST GEORG
IPC: B63B1/32
Filed: 1973-10-01
Abstract: The water craft has pref. four rotating drive propellers on a long shaft. With part-application of the drive, the craft moves in the water similar to a conventional water craft. With full power, the craft travels forward above the water. The movement is dependant upon the angle of inclination and the power. The arrangement results in there being no water drag on the outside of the hull when it is under full or nearly full speed, and raised out of the water by the vertical forces provided by the angled drives. The drive angle of the propeller shaft may also be adjustable for angle of inclination.

Title: Continuously adjustable transmission for vehicles - utilizes centrifugal force to move spherical ball members outward and operate lever mechanism
Inventor: VALDENAIRE JEAN
IPC: F16H15/50
Filed: 1974-07-29
Abstract: The unit contains a number of roller elements, supported on two running paths, one of which is stationary. The second path is connected to a drive- or take-off shaft. The roller elements are contained in an intermediate unit, which is in active connection with a shaft, so that shaft and elements rotate together. Each element is revolvable on a pivot, the axis of which may be inclined, to give a continuous adjustment of the transmission ratio. The intermediate unit and the two running paths enclose a circular seat. The roller elements are contained with free play in the seat. The supporting force of the elements on the running paths is caused by the centrifugal force, applied onto the elements by the rotation of the drive shaft.

Title: Man powered airjet driven glider - with compressed air assisted airscrew and pump linked to pedals
Inventor: BUENDER HANS-JOACHIM
IPC: B64C31/04
Filed: 1974-09-23
Abstract: The man powered glider has a pedal crank operated drive and a special airscrew with jets at the tips. The pedal linkages are fitted with piston type air pumps to supply air to lightweight reservoirs spaced around the fuselage and in the wings. The airscrew is fitted with a clutch so that the initial drive is supplied direct from the pedals, while the air reservoirs are pumped up. The pedal linkage also operates a drive to the wheels. As the glider reaches a set speed along the ground, and with the airscrew revolving at a set rate, the pilot operates a control to disconnect the airscrew clutch and couple the jets to the reservoirs. The extra power to the airscrew then provides enough thrust to lift the machine off the ground.
