Title: Ink jet printer with turbulence eliminated within electrode - has openings in electrode side parallel to ink stream
Inventor: KRAUS HELMUT
IPC: B41J2/17
Filed: 1973-10-01
Abstract: The electrode has a tubular housing of rectangular cross-section which is open at both ends. Two holders located within the housing support the two electrode halves and have suction extraction connections. The electrode halves are made of porous material and have intermediary end gaps serving respectively as an inlet and outlet for the ink jet. A high voltage impulse between the electrode halves and the ink causes an ink droplet cloud to form within the electrode. The droplets are deposited on the halves and extracted through the suction connections. In order to counteract this reduced pressure, openings are provided along the longitudinal side of the housing.

Title: Electronic touch switch for control purposes - has preamplifier, switching amplifier and triac triggering circuit
Inventor: POHL JOACHIM
IPC: H03K17/96
Filed: 1974-06-22
Abstract: The triac is used for switching the load and when a contact surface is touched, an a.c. current of phase R is allowed to flow through a transistor and a resistor of high resistance to earth. The current is used to trip the transistor and it controls a switching amplifier, so that an N-channel JFET is tripped from its conducting to its non-conducting state; this removes the shunt from a capacitor in the triac trigger circuit, and a triac connects the load; several additional control points can be provided, containing only components necessary for the pulse tripping.

Patent DE-2436435-A1 (DE)
Title: Small rotating electrical machine - has laterally-grooved balancing weights held between specially-shaped pole pieces by spring action
Inventor: SCHWEIKERT KARL
IPC: H02K7/04
Filed: 1974-07-29
Abstract: The small rotating machine has its rotor balanced by the insertion of a balancing weight (7) between its pole pieces (5). The laminar radial pole pieces have their projecting overhanging sides bent down so that they engage V-shaped grooves in the sides of the balancing weight which is then held in place by the pole pieces' elasticity. The advantage of this method of balancing lies in its simplicity (i.e. no need to machine away part of the rotor) and in its requiring no special precautions against differential thermal expansion. The spring-action of the pole pieces takes up any differences between balancing weight and rotor parts.

Abstract: A process and apparatus are claimed for the delivery of a fibre suspension, in the form of a multi-component slurry for paper making, with at least two adjacent streams of suspension passed through alternating mutual narrow mouthpieces or sets of mouthpieces with differing pressures and delivery speeds, which can also be fed by different sources of different concentrations. Where the streams unite, there is a hydrodynamic action to induce oscillation and turbulence of the particles to mix the multi-component suspensions. The system ensures that an even and consistent mixture of slurry is delivered at high speeds to the supporting mesh, with high turbulence to ensure mixture of the components.
