Title: Airship with combined hydrogen drive and position control - has liquid gas tanks and compressors driven. off main engine using gas for trim control
Inventor: DECKER KLAUS D
IPC: B64B1/24
Filed: 1975-04-29
Abstract: The airship has a number of cryotanks spaced over its frame, containing liquid hydrogen. A pump draws fuel into a heat exchanger where it is vapourised by the exhaust heat from the engine. A high pressure pump pumps the gas into the engine at the correct pressure, while excess fuel is either re-compressed and returned to the tanks, or is used to top up the airbags for added trim. The water byproduct of the gas combustion is used as a water supply for the ship and for topping up the water ballast. The airship is suitable for liquid hydrogen fuel due to its greatly reduced weight compared with conventional fuel, despite its greater volume.

Title: Waterproof hard moulded vegetable fibre plate - in which pentosan free furfural contg. slurry is moulded to polymerise all furfural using aldehyde hardener
Inventor: BASLER HERMANN
IPC: C08L97/02
Filed: 1975-06-06
Abstract: A moulded body of cellulosic vegetable fibre material comprises mainly pentosanfree furfural-contg. fibres, and is esp. in the form of a fibrous plate or fibrous drip plate contg. =50% wood chip. The furfural is pref. present in insoluble highly polymerised form. The body is moulded pref. from a fibre slurry treated with (in)organic acid to give a pH 2.0-4.5 pref. 3.0-4.0 and then compressed at 100-220 degrees C. Pref. an aldehyde hardener or its precursor is added in amt. 0.2-5 esp. 0.5-1% w.r.t. furfural content. Pref. also =100% esp. 50% of the hardeners comprise furfuramide. Pref. the slurry is pre-shaped prior to final moulding by heating to =100 degrees C under light pressure and then wetting and compressing at high pressure and 180-220 degrees C to polymerise the furfural. The organic or inorganic acid and the aldehyde hardener are added to the wettened liquid prior to final compression. The hardener is esp. formaldehyde or a polymerisation prod. of HCHO, or hexamethylenetetramine. Previous wet and semi-dry processes required use of large amts. of synthetic resin binders and use of water-proofing agents. Also only about half the furfural was usuable, the rest causing environmental pollution problems in waste. The structural integrity, strength and water-resistance of the mouldings are improved. Wet, semi-dry or dry process may be used. The polymerised furfural acts both as binder and water-proofing agent.

Title: Electrical incremental position control - uses pulse counter and D-A converter to control power amplifier with reference signal gating
Inventor: WEINLICH LEOPOLD
IPC: G05B19/35
Filed: 1975-06-19
Abstract: An incremental positioning system for machine tool applications uses a pulse counter coupled to a digital to analogue converter to control an actuating motor. The system provides higher incremental accuracy without necessitating a high operating frequency. A pulse counter operates in a bidirectional mode to drive a d-a converter supplied from a reference voltage source. Two identical a.c. voltage outputs are applied to the primary windings of a rotary resolver coupled to the shaft of a drive motor. The secondary winding generates an output for a drive amplifier, also receiving a tacho-generator output. The resolver output is gated by a pulse from reference pulse generator. The output is maintained between reference signals by a capacitor.

Title: Machine employing reciprocating motion - is for direct conversion of magnetic into electrical and mechanical energy
Inventor: MANTEY GUSTAV
IPC: H02K53/00
Filed: 1975-06-25
Abstract: A field in the form of a bar (1) with excitation windings (2) slides on a guide rod (4). At each end of the field there are cylindrical stator cores (7, 8) with ring windings (9, 10). The cores are such that the field bar is clear of one when it has fully penetrated the bore of the other. The field is attached to a flywheel (14) by a connecting rod (13) and suitable bearings. A starter motor runs the machine up from a d c source which also supplies the field winding. As the bar (1) penetrates a stator a current is set up in the stator winding and an opposing pole produced. At the end of the stroke the bar reverses direction, thus the current and polarity change and the fields are again in opposition, the stator trying to eject the field magnet. Depending on the electrical load the machine accelerates until the motion is self supporting when the starter can be switched off. In this state mechanical power may also be extracted from the flywheel shaft (15). The field can also be switched to self excitation from the stator output.
