Title: Printing head for ink jet printer - is of sandwich construction with each layer having ink guidance chambers
Inventor: STRECKER RUDOLF ING GRAD
IPC: B41J2/14
Filed: 1975-04-16
Abstract: An ink jet printer has a spray system with a gas bubble brake (8, 9) incorporated between the outlet opening (10) and the supply position (3) of the outlet channel (4). This brake opposes the ingress of gas bubbles (12) into the spray system through the outlet channel. This channel has a broadened chamber-like section (8) in its length which contains a peg (9) dividing the outlet channel into two channels (18, 28) of approx. half the cross-section of the original channel. These channels act as capillaries and are of equal length to the outlet channel, and providing a shape (8) favourable to flow relative to the outlet opening.

Title: Shaft angular velocity monitor - uses stroboscopic effect to give illuminated display of any velocity error of e.g. turntable
Inventor: VAVRINA JOSEF
IPC: G11B23/42
Filed: 1975-08-29
Abstract: In its basic form the monitoring appts. consists of a light source pulsed typically at 50 Hz, which directs a light beam at a slotted screen attached to the shaft concerned. The slots are spaced according to the nominal shaft frequency being monitored. On the far side of the screen a benched row of light pipes - each attached to a lens display - monitors the flashing light beam through the passing slots. The effect is that the middle lens display is lit only if the shaft velocity is at its nominal value. Displays to the right or left are lit for a phase lag or lead, and a travelling display corresponds to a velocity error. Double rows of slots for monitoring two velocities are also described.

Title: Flywheel body mde of curved circular plates - has uniform dynamic stress distribution, for higher speeds
Inventor: DAMMANN PETER DIPL ING
IPC: F16F15/30
Filed: 1975-09-12
Abstract: A flywheel suitable for a vehicle has a central shaft (1, 2) which carries the flywheel body (3). The flywheel body consists of circular plates which are pressed into spherical shaped curved discs. The discs (3) are arranged on the shaft so that between the two sets of plates, an enclosed space (4) of convex shape is obtained. When the flywheel is spinning, the curved plates (3) tend to straighten due to the action of centripetal force. Due to the resulting change of shape of the flywheel body, its internal stress distribution is uniform, thus higher rotating speeds are permissable.

The by-product length cutting may be carried out behind the lengthways cutting appliance (5), in the direction of forwarding. The by-product cutter (7) may be a chain saw circular saw, or other form of blade.
Patent DE-2549019-A1 (DE)
Title: DC load current suppression in rectifier circuits - uses forced commutation path in parallel with load with thyristor capacitor and choke
Inventor: MUELLER REINHOLD
IPC: H02H7/127
Filed: 1975-11-03
Abstract: The application is to circuits where the load current must be suppressed rapidly in the event of an overload, the d.c. power being supplied by a controlled rectifier (1). To achieve this a commutation circuit comprising a thyristor (31) in series with a capacitor (32) and choke (36) is connected to the anodes of the controlled devices (11, 12, 13) in the rectifier, and in parallel with the load (2). A reverse biased diode (21) may be connected across the load to assist the process. If an overcurrent is detected the commutating thyristor (31) is triggered, and discharges the capacitor into the load assisting the collapse of current therein, the load being virtually short circuited. Current is also shunted from the conducting main thyristor (11, 12 or 13) and the affected device ceases conduction.
Patent DE-2551089-A1 (DE)
Title: Underfloor hot water heating using plastic pipes - has pipes crossing each other at the bends between straight runs
IPC: F24D3/14
Filed: 1975-11-14
Abstract: A network of pipes is laid on a floor under the finished floor surface. The pipes are supported on two plastic cross pieces which have holes (14) at regular intervals between any two adjacent straight runs is thus a multiple of a basic module dimension. At two opposite edges of the room the straight lengths are joined by bends (15, 16) to form a continuous coil. The bends vary in diameter and the pipe can cross over itself at the bends. This can happen either at one side of the room only or at both sides. The crossing over enables the concentration of pipes in the floor to vary between different parts of the floor.

Title: Digital multiplex telecommunication system - has concentrator for incoming subscriber lines and several memory units
Inventor: WURST WALTER KENNETH
IPC: H04Q3/60
Filed: 1975-12-04
Abstract: The telephone network multiplex system includes an exchange accommodating typically 128 incoming subscriber lines brough into 4 X 32 channels. The incoming feed lines go to a concentrator which is followed by a digital memory, the first unit of which indicates the position of the line in the channel. The second and third memories deal with the status of each subscriber call relative to that of other calls in the system. Having passed the third memory, a fourth memory unit comes into operation and connects a line transmission unit to couple a line to the signal accepted by the first memory. Each memory is associated with a decoder to decode the digital signals if required for further transmissions.

Title: Blooming-slabbing mill control - by computer controlling screwdown devices for even specific output distribution over stands
Inventor: LOON DIRK VAN
IPC: B21B37/22
Filed: 1976-12-30
Abstract: A blooming/slabbing mill is controlled by a computer which calculates from the output curve the specific output required for each rolling mill stand. It determines the reduction distribution and checks that the threshold for length, angle of contact and roll force are not exceeded. After calculating from the roll force the stretch for each stand the roll screwdown is determined, with an allowance for stretch and a correction for play and roll deflection. This relieves the operator of the necessity to adjust the blooming/slabbing mill stands. The extent of damage caused by errors in adjustment is reduced, the wear is less and there is less rik of breakages. The velocity settings for the upset pass rolls are more accurate and the product has a more uniform width.

Title: Gas fired radiant flat heater panel - has porous surface combustion panel and edge flow reducing fuel losses
Inventor: SMITH THOMAS M
IPC: F24C3/06
Filed: 1977-04-02
Abstract: The gas fired radiant heater has porous fireproof panel and the gaseous fuel mixt. is burnt on the panel surface. The edges of the panel are closed and the combustible mixt. is supplied from a chamber through the porous panel to reach the combustion surface. A narrow stream of relatively cooled noncombustible gas is passed through the panel directly adjacent to the panel edge support during the combustion for improving the combustion results. The noncombustible gas is supplied through the edge frame channel which has gas outlet opening. The noncombustible gas passes through the panel over the entire edge length. This arrangement ensures that the combustible mixt. in the chamber is not able to escape through the panel edges. The porous fireproof panel can be a statched fibre mat or a panel made from felted fireproof fibres. The panel narrow edge is closed by a profile preventing escape of gas from this part. The panel edges are compressed so that its thickness is reduced by about 10% for preventing losses.
