Title: Recharging system for flywheel powered vehicle - with high frequency converter for high speed charging from three phase motor
Inventor: HAGIN FAUST
IPC: B60L9/28
Filed: 1975-12-24
Abstract: The public service vehicle is driven by a flywheel, which drives a DC motor to provide current for the wheel motors. The flywheel is recharged at the stops by an electric contact (2) to a three phase supply above the top. The flywheel is spun at an enhanced speed using a three phase high frequency motor, with the supply frequency increased by a frequency converter. The flywheel mass and size can be reduced considerably, with the higher speed. The vehicle can also be fitted with a normal engine for use in country areas where there are wider distances between stops.

Title: Local to central fire alarm coupling unit - allows special practice signal to be transmitted when coupler circuit door is open
Inventor: ROFLER LEONHARD
IPC: G08B29/14
Filed: 1976-02-27
Abstract: An opt-electronic coupling unit is incorporated in a simple coupling equipment for use in coupling a local fire alarm transducer or system to a central system. This permits the transmission of a special practice signal when the coupler door is open and avoids a telephone call to the central system when a practice alarm is to be triggered. The coupling circuit consists of a.l.e.d. and photosensitive transistor, which link the incoming local line (HAL) to the outgoing central alarm line (HML) without electrical connection. A switch (TK) in the coupling unit door switches the outgoing line to another circuit which can be prompted, in a practice run, to send a signal of its won characteristic frequency to the central alarm. The real case circuit is reconstituted when the door is closed.
Patent DE-2619639-A1 (DE)
Title: Electric load time or current monitoring - switches on timer only when current is being drawn by that load
Inventor: BINDZUS HEINZ
IPC: G01R19/145
Filed: 1976-05-04
Abstract: The time or current monitoring circuit for use with electric leads such as motors, times the load time or current of the machine on the alternating current supply. The network produces more accurate results than simply attaching a timer or ammeter to the machine terminals, since the monitor operates only when a refined load current is being taken. Basically, a full wave bridge circuit comprising si diodes is mounted in the alternating current supply to the machine or load. When a load current flows the voltage drop across this switches on a relay (7) via a light diode isolator circuit (9) and two stage (11, 12) darlington pair amplifier. The relay connects a timer or ammeter to the supply as required. When current monitoring is required an adjustable timer (13, 14, 15) allows machine starting currents to be accommodated.

Title: Photothermoplastic film charging esp. for holography - with opposite charged electrodes on opposite sides of film
Inventor: CLEMENS PETER DIPL PHYS
IPC: G03G16/00
Filed: 1976-05-07
Abstract: Device for charging a photo-thermoplastics film comprises a film feed mechanism, a corona electrode of determined polarity and a second corona electrode of opposite polarity on the opposite side of the film. Both electrodes do not contact the film. Device is for holographic recordings, esp. for information processing immediately after exposure of the film e.g. in materials testing. The film may be used again after deletion of the image. Film speeds are pref. 3 cm/sec continuous or 10 cm/sec. mean, for intermittent feed. Absence of an earthed electrode in contact with the rear face of the film eliminates wear of film and electrode and frictional interference with the smooth motion of the film.
Patent DE-2631194-A1 (DE)
Title: Power supply for HV line light current equipment - is transmitted by optical link which has damping factor within fibres
Inventor: CASPERS FRIEDHELM DIPL ING
IPC: H02J13/00
Filed: 1976-07-10
Abstract: The measurement of line quantities, and the transmission of control information of HV lines, brings insulation problems for the light current equipment, in particular the provision of power supplies. This problem is overcome by using a dielectric link of optical quality, and transmitting the necessary energy in the form of light. For example the transmitting end may be equipped with LED's or laser diodes and the receiving end may be a photo-voltaic cell or a solar cell. As the spacing between HV line and earth for a 500 kV system is about 2m. the optical link using high quality high light guides is practically loss free. The same light guide material may also be used for hf transmission of control signals in optical form. The damping of such fibres is of the order of 100dB per km and can therefore be neglected.

Title: Temp. responsive switch - has snap action bimetallic disc making or breaking contact with riveted terminals
IPC: H01H37/54
Filed: 1976-10-01
Abstract: A temp. responsive switch for control of electrical equipment has a bimetallic disc that adopts one of two stable positions. Electrical contacts (4) are rivetted to the insulated top cover (3) of the switch. The circuit across the contacts is made by a silvered layer (9) on the surface of an insulated disc (8). The disc position is determined by a disc spring (12) and a bimetallic disc (11), retained by a centre pin (10). As the temp. increases, the bimetallic disc deflects to break the electrical contact. The disc passes through the dead point and exhibits a snap action effect in adopting the second stable position.

Title: Surface aerator for sewage tanks - with impeller shroud duct turning rising fluid flow ninety degrees outward over surface
Inventor: KAELIN JOSEPH RICHARD
IPC: B01F3/04
Filed: 1976-10-29
Abstract: A surface aerator for sewage aeration tanks consists of a direct driven axial-flow pump impeller which is fully shrouded. The shroud rotates with the impeller and continues above the fluid level with an outlet which is deflected through 90 degrees outwards and projects the water in a spray across the tank surface. The direct drive saves the reduction gear and the higher speed results in a greater range of throw. The fluid is kept longer in contact with the ambient air and the oxygen pickup is improved.

These acids are differentiated from known phosphonic acids in that H atoms on the N atoms are replaced by alkanesulphonic acid gps. They are easily prepd. in good yield, and have excellent solubility in aqs. media (>=100g/100ml). They complex well with bi- or multi-valent metallic ions, and have good resistance to hydrolysis, even above 100 degrees C. They can be used to counteract water hardness e.g. in textile treatment, paper making, and tanning.

Abstract: The counter-boring tool has a shank (11) with four equally spaced radial blades (15-17). The angle of the cutting edges (18) on the end faces of these blades lies between 30 deg. and 35 deg. The helix angle of the outer edges (39, 40) of the blades lies between 40 deg. and 45 deg. w.r. t. the shank axis (12). The helix angle of the root (41) of the blades lies between 20 deg. and 25 deg. w.r.t. the shank axis. The front and rear edges of each blade run parallel to each other. The rear face of each blade lies approximately in a plane which is tangential to the shank surface. This design of cutter requires less operating power and has a much longer service life than conventional counter-boring tools.
