Title: Combined thermal catalytic recuperative exhaust gas burner - has gas permeable catalyst for exhaust and burner gases
Inventor: TABAK FERNANDO
IPC: F23G7/06
Filed: 1974-04-13
Abstract: The recuperative exhaust gas burner uses reduced amounts of thermal energy for burning of contaminants. This burner has a gas permeable catalyst cylinder (12) which encloses a combustion chamber with burner flame. The annular space (5) outside the catalyst forms a heat exchanger with axial pipes (4). Contaminated exhaust gases enter axially in a direction against the flame and treated exhaust gas leaves the burner through a lateral outlet (16). Contaminated gases enter axial pipes (4) arranged between the outer shell and the catalyst. These pipes duct the exhaust gases to the other, flame end of the burner where they are entrained by the flame.

Title: Hot-rolling of steel bars and steel wire - uses six continuous tages of production(BR-10.2.76)
Inventor: TAKASHIMA AKIHIKO
IPC: B21C47/24
Filed: 1974-08-24
Abstract: The procedure uses wire in coils or bundles. In a first stage, the continuous welding together of ends of wires in successive wire bundles, forms a long continuous wire.

Title: Battery operated watch - uses mark-pulse ratio of square oscillator pulses for linking battery to transducer
IPC: G04C3/14
Filed: 1974-09-05
Abstract: A battery operated watch saves power and combines insensitivity to shocks with high accuracy. The square output pulses of an oscillator, pref. an integrated circuit, with a mark space ratio of 1:20 to 1:100 (1:50) allows adequate time for the miniature battery to recover. When the transistor is ON, the coil of the electromechanical transducer moves a lever with a stepper arm to advance the escape wheel from tooth to tooth. The energy source should be placed parallel to the oscillator which, in turn, is parallel to the electromechanical transducer. Thus it is possible to connect the circuit of the transducer direct to the energy source, so that their total internal impedance, and not only that of the oscillator, can be serviceable.

Title: Fixing bearing inner ring on shaft - using clamping ring placed over end
Inventor: MAYER ERNST DIPL ING DR
IPC: F16C35/063
Filed: 1974-10-30
Abstract: The bearing inner ring is partly cut away at one end and leaving several prongs extending from that end, alternatively, a slot is cut in the bearing ring near its end. A ring is placed over the end of the bearing ring. The bore of the ring has local reductions in diameter, so that when the ring is twisted round, the local sections where the radius is reduced will force the prongs on the bearing ring inward and secure the bearing ring on the shaft. In an example an thin-walled inner ring is fitted on a shaft (2). At one axial end two oppositely placed projections (3) cover a section of the circumference. The clamping ring (4) is fitted within this region.

Title: Radio car communication system with transmitter identification - has range characteristic blocked during transmission characteristic radiation
Inventor: GROSSMANN WERNER DIPL ING
IPC: G08G1/09
Filed: 1974-11-11
Abstract: The car radio communication system recognises a transmitter belonging to the traffic communication network by radiation of an auxiliary carrier of preferably 57 kHz, amplitude modulated with frequencies in the range of 20 to 125 Hz. One such frequency transmitted during the programme forms the range characteristic the other one forming the transmission characteristic, being used only during transmission of the traffic messages. During the transmission of the message characteristic the range characteristic is blocked and a frequency is additionally transmitted as partial range characteristic or given road sections of the overall range. This frequency controls an electronic switch in the LF part of the car receiver, thus activating the loudspeaker.
