Title: Electrical hair care implement - has heat recorder with two thermostats of different sensitivity with air turbulence device
Inventor: HUEBNER OTTO
IPC: A45D20/18
Filed: 1977-11-03
Abstract: The electrical hair care implement consists of a motor blower with a heat recorder and housing, to whose outlet a heat-resistant additional component can be connected.

Title: Monitor for inverter bridge commutation - uses signals from current pick=ups in bridge diagonals which are added and trip signal when sum is too large
Inventor: MATTHES HANS G DIPL ING
IPC: H02H7/122
Filed: 1977-12-02
Abstract: The investor output is connected to an oscillating circuit. The invertor thyristors in opposite bridge branches are ignited in opposite phases by a control circuit, so that current flows through one diagonal in one half-period, and through the other diagonal in the other half-period. A current pick-up is inserted in each diagonal, whose output signals commutation disturbances to a switching device. The switching device sensitivity abruptly changes from zero to a maximum in synchronism with the invertor frequency. The switching device (20-25) sensitivity is a max. around the commutation instant, and zero during the remaining time. An adder (24) totals commutation signals, and a signal is tripped when the sum exceeds a threshold.

Title: Mixed fodder preparation machine - with mixing carriage attachable to hammer mill and movable to mangers
Inventor: CRAMER LUEPPO DIPL KFM
IPC: B01F13/10
Filed: 1978-02-02
Abstract: A machine for the prodn. of mixed fodder for animal farms consists of a mixing carriage on four wheels, with a horizontal and a vertical work conveyor. This can be matched with the discharge opening of a hammer mill for cereals.

Title: Monitor using transceiver and memory - compares radiation returned and altered by transducer carried by object or subject in supervised zone
Inventor: ROBERTS GRAHAM MARSHALL ISLWYN
IPC: H04H60/45
Filed: 1978-04-28
Abstract: The closed circuit TV monitor identifies objects inside a certain zone. It has a radiation transmitter and receiver, sending the radiation into, and receiving it from the zone. The objects carrys a transducer (65) which affects the radiation in the zone received by the receiver (32). The transducers have properties which have different influences on the radiation. A memory (73) stores these properties, and a comparator (74) compares the received radiation with the stored properties in order to detect which transducer (65) is in the zone. A store stores the previous determination of the transducer (65) position or place, and a comparator compares the stored with the current values, in order to find which transducer (65) has entered or left the zone between the preceding and current time interval. The current determination is stored for further use.

Title: Electric oil level indicator for IC engines - is by float adjusting potentiometer wiper through connecting rod
Inventor: JUHASZ JOSEF
IPC: F01M11/12
Filed: 1979-02-03
Abstract: The oil level measuring and indicating device is for the lubricating oil in the sump (2) of an I.C. engine and consists of a float (4) with a rod (5) to adjust the wiper (6) of a potentiometer. A control unit (10) energises a relay (9) only when an engine has been stopped after a run and after a waiting time of 2 minutes, and keeps it attracted only long enough for the oil indicator (S) to reach its reading. The attraction of the relay (9) closes by the contacts (K) a power supply from a battery (B) and this causes the moving coil of the indicator (S) to set a pointer to the oil level. When the contacts are opened, an armature of an electromagnet unit (S) is released and brakes a disc on the pointer shaft. The reading is therefore maintained until the engine is started up again to show the driver the oil level before every run.
