Patent DE-2336812-A1 (DE)
Title: Electrical control system for ink jet printer - regulates charge amplitude of droplets passing through constant static deflection field
Inventor: KASUBUCHI TAKESHI
IPC: B41J2/12
Filed: 1973-07-19
Abstract: The series of ink droplets are formed using a nozzle, an electromechanical ultrasonic convertor and a charging electrode relative to which moves the recording track. The droplet charging generator has an amplification control unit whereby the droplet charge is proportional to the duration of the impulse of the rectification control signals. These signals are produced by a flip flop responsive to the recording signals and the control signals for droplet formation. The control signals are produced according to whether droplets are present or absent and thereby the charging amplitude of a successive ink droplet is correspondingly regulated.

Title: plasma burner with high enthalpy and velocity - cathode shielded from oxygen gives long burner life
Inventor: SCHRENK WILHELM
IPC: H05H1/32
Filed: 1973-08-30
Abstract: The arc is formed between a cathode-rod with high temp.-resistance and a ring anode of much larger dia. mounted in the funnel-shaped jet; aggressive media cannot attack the cathode. The core of the bu rner contg. the cathode is insulated from the jet so an electric potential can be applied. As compared with the usual burners using two electrodes which only have a life of a few minutes, this burner has been in use over 170 hours; it needs neither a mixing chamber nor a magnetic field.
Patent DE-2348764-A1 (DE)
Title: Fire-resistant double floor of panels on supports - with fire-protective strips embedded in shaped-section extending from support to support
Inventor: PALLHORN SEBALD
IPC: E04F15/024
Filed: 1973-09-28
Abstract: The floor panels are laid on supports, with fire-protective strips running along their joints, to check fires originating in cables or other under-floor services from spreading into the room above. Here resistance to fire is increased by using fire-protective strips which are embedded into shaped-sections, each of which stretches from one support to the next. Laying of double floors is simplified, with no need for additional treatment of the floor panels, and joints are quickly and effectively sealed. The shaped-sections are of metal, for good heat conductivity.

Patent DE-2412816-A1 (DE)
Title: Automatic combine-harvester safety-device - preventing inadvertent operation of grain-tank-emptying screws
Inventor: BUSSE WILFRIED DR ING
IPC: A01D41/12
Filed: 1974-03-16
Abstract: The lowest part of the grain tank houses an emptying screw connected with an extra screw by means of universal joints, an intermediate shaft, a drive shaft and chain drive. The extra screw is positioned in the grain tank discharge pipe which is next to the grain tank outlet and pivots in a ring mount. The grain discharge pipe has a track on which is a roller connected to a transmission rod which acts on the pressure roller for the drive belt. The shape of the track on the grain tank discharge pipe is such that when the emptying pipe is swung outwards, the pressure roller tightens the drive belt by means of the transmission rod and roller. The pressure roller moves away from the drive belt so that the connection between the drive shaft and grain tank emptying screw is broken.
Patent DE-2419243-A1 (DE)
Title: Electropneumatic anti-skid brake control - with increased response using ballast volume in control line to valve
Inventor: ECKART ALFRED
IPC: B60T8/50
Filed: 1974-04-22
Abstract: The electropneumatic control valve regulates the brake pressure on the wheel brakes in response to control signal pressures on the input of the valve. When the valve is used in an anti-skid control then the response time of the system is too slow to prevent the brake pressure from being modulated too far. The invention provides a ballast air volume coupled to the input of the control valve. This is connected to the system by a variable throttle valve and a non-return valve. The system prevents the control pressure from falling too far and enables a rapid response system to be established.

Title: Small substation ventilation duct with self closing shutters - prevents the escape of hot gases following a fault by acting as an expansion chamber
IPC: H02B7/08
Filed: 1974-10-30
Abstract: In buried or partially buried small substations an air duct (4) is normally provided which connects with the equipment below ground level. In the event of a fault giving rise to arcing inside the equipment it is undesirable to let the hot gases escape from that part of the housing (2) above ground level as it presents a danger to passers by. The air duct (4) is therefore proportioned to fulfill the dual role of duct and gas expansion chamber, and is fitted, on the normal air inlet side, with hinged louvred shutters (24) which close when the pressure in the chamber suddenly rises. An additional shutter of the same type may also be provided between the housing and the duct.

Abstract: An electromagnet to operate a magnetic valve, actuated by an a.c. or pulsed d.c. current, has a coil (11) at the output of a rectifier bridge (13) and in series with a triac (14), which when actuated by closing the supply switch (15), passes a higher value current during approximately a half period, then afterwards the holding current through the coil falls to a lower value with an increase in the phase lead angle. This is controlled by an arrangement of a pulse emitter (16) connected by two branches (17, 18) to a zero current counter (19) connected to a voltage divider formed by two resistors (22, 23) across the supply forming a changeover system giving the change in the phase angle.
