Title: Stator with end plate and finger assembly of reduced height - has nonmagnetic steel pressure fingers located in grooves
Inventor: DUKSCHTAU ALEXANDR ANTONOWITSC
IPC: H02K3/42
Filed: 1975-02-20
Abstract: The stator of an electric machine has a box core with magnetic steel end plates that press the core laminae together via non-magnetic steel fingers. These pressure fingers (6) are located in grooves (7) in the plates (5). The grooves extend radially with respect to the stator axis (1). The arrangement reduces the height of the compressing devices (plates and fingers) and thereby reduces the size of the stator core and winding. The overhang of the stator winding bars can be reduced by 100 to 120 mm, which also increases efficiency and reduces materials costs.

Title: Printing head for ink jet printer - has several outlet channels with capillary openings facing printing paper
Inventor: RITTBERG EILT-HEYO DIPL ING
IPC: B41J2/14
Filed: 1975-02-25
Abstract: Compression chambers filled with e.g. an inert gas are connected with the capillary channels. The relatively compressible gas has a low vapour pressure and temperature coefficient and is chemically inactive relative to the walls of the compression chambers. A film is arranged between the gas in the chambers and the printing ink in the capillary channels. More specifically the inert medium is a liquid which is in direct contact with the printing ink but is immiscible with it. A bead of quicksilver may be positioned between the medium and the ink. The capillary channels have conical shaped enlargements at their ends nearest to the film. This readily manufactured printing head facilitates uniform droplet formation.

Title: Underwater structure anchored by granular material - is lowered through mud layer displaced by pressurised water jets
Inventor: VOGEL RUDOLF DR ING
IPC: E02D27/52
Filed: 1975-09-29
Abstract: An offshore drilling platform has a structure anchored on the sea bed, readily installed even if thick layers of mud are present. On installation the structure support is at first held above the underwater mud layer resting on the load bearing surface. The mud is displaced by fluidisation and displacement by using pressurised water. The structure is lowered and penetrates the mud layer while the pressursed water jets displace the mud.

Title: Anodic protection of chemical plant against corrosive media - using electric circuit to maintain passive film on plant
Inventor: MOJSA VLADIMIR GRIGOREVITSCH
IPC: C23F13/00
Filed: 1976-08-20
Abstract: An object in contact with an electrically conducting medium is protected against corrosion by placing a cathode in the medium, and periodically applying a polarising current, so the object forms an anode and the electric potential is kept within prescribed limits. During the intervals between the supply of the polarising current, the cathode is short-circuited to the anode. Method causes passivation of the object e.g. appts. and tanks used in the chemical-, food-, and textile- industries, and in mfg. cellulose or paper. A stable passive film is formed in the tank or other object.

Title: Sewage aeration device - using revolving hollow bodies with slots on top when emerged above fluid level
Inventor: STAEHLER THEO
IPC: C02F3/10
Filed: 1976-08-27
Abstract: Foreign matter, such as faeces, in sewage is converted into innocuous substances by revolving horizontal shafts in conversion or sludge aeration basins. Hollow bodies (cylinders) which are moved by the shaft to dip fully into the fluid and emerge entirely above it are fitted with slots only on the part of their walls which lines on top when they emerge above the fluid level. Intimate contact with air, trapped in the hollow bodies on the down path, is ensured as the air escapes through the slots on the upward path. The revolving assembly circulates all the fluid in the basin and aids in the conversion of the faeces by oxygen in the air.

The exhaust flap is at the same time formed as an exhaust brake flap. The thermostat (16) is fitted with a pipe or rod shaped flexible link used as a temp sensor.
Patent DE-2642555-A1 (DE)
Title: Joining leading end of uncombed sliver to tail of combed sliver - by advancing leading end onto reversible belt supporting tail of combed sliver
Inventor: GROSSI OSCAR
IPC: D01G19/20
Filed: 1976-09-22
Abstract: The leading end of a sliver to be combed is guided by clamp elements onto a rotating comb to comb and open the leading end whilst the trailing end of a sliver which has already been combed is supported on a belt supported between a main roller and a grooved support roll. The direction of movement of the belt is reversible so that the rail of the trailing end of the sliver can be caused to overhang the belt and extend into a duct to which a suction is applied. When the leading end of the sliver has been combed a wall of the duct is e.g. pivoted to hold the tail of the sliver against the belt, and the clamp elements release the leading end of the sliver so that it can pass via a guide comb onto the belt. The direction of movement of the belt is then reversed so that the leading end of the sliver is superimposed on the tail of the sliver. A grooved wall co-operating with the grooved support roll acts on the slivers to ensure the fibres mix and the two slivers are joined together. The mechanism is simpler than conventional arrangements for joining sliver together.
Patent DE-2649365-A1 (DE)
Title: Electronic control of fuel injection IC engine - uses Schmitt trigger to respond to engine temp. and acceleration for clean combustion
Inventor: DOEMLAND CHRISTOPH ING GRAD
IPC: F02D41/10
Filed: 1976-10-29
Abstract: A signal (a) from the inlet manifold of a vehicle internal combustion engine provides an input proportional to the engine acceleration. This is fed through an amplifier (5) and a smoothing circuit (8, 9, 10, 11) and a differentiating circuit (12, 13) to the inlet of a Schmitt-Trigger operational amplifier (2). The output of this is connected to an impedance transforming operational amplifier (4) which receives an input (g) from a temp. transducer on the engine. The combined output (e) of the two amplifiers (2, 4) depends on the acceleration and the engine temp. and is fed through an amplifier (6) to the fuel injection controller. The circuit ensures that the fuel quantity is increased for acceleration without pollution in the exhaust of the engine.
