Patent DE-2346153-A1 (DE)
Title: Mixer for liquids and pastes - with pumping effect, absence of dead spaces and simultaneous injection of constituents
Inventor: SKIBOWSKI HUBERT
IPC: B01F25/74
Filed: 1973-09-13
Abstract: A cylindrical mixer has a number of ports in its upper chamber for the simultaneous injection of constituents and additives. The quantity of each constituent is controlled by a poppet valve whose seat is flush with the inside surface of the chamber. The components flow alternately towards and away from the centre of the mixer downwards over a series of rotor and stator blades. The mixing is effected by rotation of the rotor, which also helps to pump the mixture through the mixer and empties it after the mixing operation. The direct mounting of the inlet valves and the internal shape of the mixer are designed to eliminate "dead-zones". The mixer has small physical size in relation to its capacity and a number of mixers can be placed in series. Incorrect proportioning due to residues in "dead-spaces", is eliminated and only slow rotation of rotor is needed to achieve homogeneity. Resistance to flow can be varied using the rotor and wastage is reduced.
Patent DE-2346885-A1 (DE)
Title: Alarm activated by pressure change - raises signal when air, pumped through flexible tube, meets increased resistance
Inventor: CZERNY GEB ZERRES ERIKA
IPC: G08B3/06
Filed: 1973-09-18
Abstract: An alarm signal is given when a mechanical pressure value is exceeded. A modified, yet otherwise customary swinging lever pump fills a flexible hollow tube with a flow of air. When the air flow encounters a resistance greater than a predetermined value an alarm is raised. The swinging lever can be arranged to mechanically operate an alarm bell or it can complete an electrical contact. An application of the invention would be a placement of the tube on a balcony bar in order to give an alarm when a baby or small child came into contact with the latter, so preventing a dangerous situation arising.

Title: Operating data feeders switched as capacitors - with multilayer metal-isolator-semiconductor and metal elements used as data feeders
Inventor: MOORE JOHN S
IPC: G11C11/23
Filed: 1973-11-22
Abstract: The feeder region lies in an isolator in the range of the border surface near the semiconductors. During feeding the surface of the feeder is entirely positively charged. Positive charges on the one side are kept in tasct and on the other side discharges are effected with a beam of dia. corresponding to semiconductor electron path length. Positive charges are obtained by bombardment with ionised radiation with such energy that they can infiltrate into the isolator layer and make it positive w.r.t. the semiconductor layer. For reading the recorded data a beam is used whose intensity is sufficient to penetrate the feeder region. Data recuperation is effected by reading and recording. The effect of electron dispersion is limited. The layers of the block comprise the isolator layer, semiconductor layer, and conductor layers and the block can be regarded as a capacitor whose plates hold charges.

Title: Manufacture of folding joints - folded sheets are fed between two sets of rollers
Inventor: MARX LUDWIG
IPC: B21D39/02
Filed: 1974-02-01
Abstract: The arrangement consists of a vertical plate on which two horizontal rollers are mounted which are driven via gears by an electric motor. A second vertical plate which also has two rollers is guided by pillars so that it can move up and down. The distance between the two sets of rollers can be adjusted by a screw and nut so that it can be matched to the thickness of the folded metal passing between the rollers. A lever with eccentric is mounted on top of the adjustable plate with which the rollers are forced against the fold passing between the rollers. One of the rollers in the bottom set has a central groove, while its mating roller has a notch which presses the metal into the groove.

Title: Peristaltic pump for heart - preventing damage to blood uses sequenced set of valves for oil surrounding tube
Inventor: WALTERSPIEL JUAN N
IPC: A61M60/284
Filed: 1974-05-15
Abstract: Peristaltic pump which is used as an artificial heart pumps liquid on one direction by peristaltic-like waves which are produced by alternating suction movements by a hydraulic fluid surrounding a tube of elastic material, e.g. silicone rubber. The hydraulic fluid is contained in an outer metal pipe with openings for passage of fluid. The silicone rubber tube is compressed in waves moving in the pumping direction and valves which produce overpressure and underpressure via the openings are electrically controlled according to follow a given time sequence. Some of the valves are opened to admit overpressure to squeeze the tube while some of them are opened to admit underpressure to allow the tube to expand.

The crossbar distributor is connected on the pickup side to at least a second crossbar distributor, by which the instrument measurement terminals are allocated to central comparators. One of the comparators can be connected as a "bridge" which can then be freely allocated to the terminals. A third crossbar distributor is allocated to the pickups, by which several instrument terminals can be allocated to a common pickup. All crossbar distributors are mounted in a common housing together with terminal strips.

Title: Circuitry for medium frequency inverter - has control cct with voltage comparator and current measurement covering peak loads
Inventor: SIEPMANN BERND JOSEF
IPC: H02M3/335
Filed: 1974-09-20
Abstract: The circuitry for a medium frequency inverter is designed to cover high peak loads. A switching transistor in the input circuit is alternately made conducting and blocking by means of a square wave a.c. voltage. The generated a.c. voltage in the primary winding of a repeater is caused to produce one or several stabilized d.c. voltages in the secondary circuit by means of rectifiers. No large storage capacitors or filter chokes are necessary on the secondary side, while on the primary, a much smaller storage capacitor can be installed since a higher working voltage is used in the primary than in the secondary.

Title: Front-loading dishwasher with pull-out crockery trays - has space-saving roller guide allowing maximum utilisation of interior space
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: A47L15/50
Filed: 1974-09-24
Abstract: The front-loading dishwasher has an upper crockery tray guided in rails and a lower crockery tray which can be extended in drawer-fashion whereby its front rollers run on tracks inside the door whilst its rear rollers run on supporting rails in the wash chamber. So as to increase the effective height available for loading the lower tray the tracks are sunk into the door whilst the supporting rails run inclined from the front load opening towards the rear wall of the wash chamber. The front rollers of the lower tray are preferably off-set by one roller width sideways in the gauge relative to the rear rollers so that, when the tray is slid in, the front rollers are lowered in the tracks whilst the rear rollers are lowered on the supporting rails.

Title: Ventilation device for stables and other closed spaces - with aperture-flaps having overweight in aperture-direction and current-regulated closure-piston
Inventor: MICHELBACH ALFONS
IPC: F24F7/003
Filed: 1974-10-30
Abstract: A ventilation device for animal stables and other large closed spaces comprises a fan-driven outlet-vent and passive fresh air supply through apertures in the ceiling of the room. These apertures can be closed by means of flaps, located below each aperture. These flaps have overweight in the direction of aperture and, in the direction of closure, are under the action of a working piston, which can be activated and regulated by means of current supply. The remote-control flaps thus take up their open position in case of breakdown of current supply.
