Title: Stackable spool for magnetic tape recorder - has projections extending up and down and acting as pegs, for locating in adjacent spool in stack
Inventor: KREEFT HENDRIK K
IPC: B65H75/18
Filed: 1978-10-12
Abstract: The spool comprises a flat ring having a thickness equal to the width of the tape to be wound onto it. The upper and lower faces of the ring have profiled regions that interlock with corresponding regions on adjacent rings when spools are stacked. The profiled regions consist of projections extending upwards and downwards from the plane of the ring in alternative directions in passing around the ring. An up projection is separated from a down projection by a recess shaped to accommodate either an up or down projection of an adjacent spool. The up and down projections thus act as locating pegs engaging recesses in adjacent spools. They are identical.

Title: Propeller with blades foldable upstream - has blades mounted on swivel bearing and aerodynamic and centrifugal loads are balanced in working position
Inventor: OEHLER CLAUS DR ING
IPC: B64C11/28
Filed: 1978-12-20
Abstract: The propeller has blades(1) which fold upstream or, in a retractable unit, against the direction of retraction. It can have two or more blades. Each blade is flexibly connected to the hub(2), e.g. by a swivel-bearing, in such a way that when the propeller is working the blades adopt an angle at which centrifugal and aerodynamic loading is balanced. There is thus no bending stress in the connection. Folding is effected by moving the assembly to bring the blades up against a fixed object such as the edge of an opening in the fuselage.

Title: Power supply including feedback transformer - which couples output back to primary-side pulse-width modulator, and receives meander-shaped voltage waveform
Inventor: ROSENTHAL HANS-DIETRICH
IPC: H02M3/335
Filed: 1979-05-17
Abstract: The power supply has a transformer (19) to feed the output voltage (C) or a fraction of it back to the primary side of the pulse width modulator (3) on the primary side of the mains part.

Title: Polyether soft foam for upholstery fillings - comprises rhomboidal particles of specific dimensions
Inventor: LUECK WERNER
IPC: B68G1/00
Filed: 1979-05-19
Abstract: A four-sided rod cut from stock, soft, synthetic foam blocks, such as of polyether, having a density of 40 kg. per m.3, to be used as a filling for bolsters, upholstered furniture, cushions, etc., as described in Parent Patent is modified.

Title: Balancing network for reference voltage in FET module - provides biassing voltage with low avalanche effect at pn junction and substrate
Inventor: ROESSLER BERNWARD DIPL ING
IPC: G05F3/24
Filed: 1979-09-21
Abstract: A balancing system is for a reference voltage in an integrated FET module. It has two separate stages supplied from the same direct current source and contains a series connection of an IG- FET and a working resistor. The differential voltage between the two tappings is used to establish the reference voltage. A high biassing voltage which has a small avalanche effect is applied to the PN junction between the drain (D) and the source (S) on the one hand and the substrate (Su) on the other hand. A short-wave electromagnetic radiation is fed to the biassed drain and source because of deficiency in diffusion.

Title: Time multiplex control system for remote stations - uses timing system to transmit continuous signal at frequency higher than control signals
Inventor: STEIN HERMANN
IPC: G08C15/06
Filed: 1980-04-03
Abstract: The time multiplex control system for a number of receiving stations receiving control signals from a central transmitting station, uses control signals with sections which are transmitted at a high frequency. The timing circuit which controls this frequency has timed groups of time constants which are independent of periodic signals received by the receiving section of the central transmitting station, are released in synchronism. The central transmitter sends continuous signals at a high frequency differing from the frequency of the common control signals. The timing system uses a quartz controlled clock pulse generator connected to a divider followed by a ring counter connected by an AND gate and delay system to the transmitter. This keeps the time constants constant corresponding to the time period of the periodic signals. The divider and a phase equaliser controls the clock pulse frequency so that it is maintained as a multiple of the synchronising frequency and the divider chain of the clock pulses is of the same phase as the synchronising signals.
Patent DE-3014350-A1 (DE)
Title: Label scanner for identifying objects - automatically determines angle between scan direction and marker lines on label to avoid errors in reading
Inventor: WEVELSIEP KLAUS DR
IPC: G06K7/10
Filed: 1980-04-15
Abstract: The label consists of patterns of marker lines. The marker lines within each pattern are equally spaced. The patterns may be scanned along a scan line that is inclined to the centre axis through the pattern, i.e. the axis is orthogonal to the marker lines. The number of scan lines scanned during each scan is counted and stored as a first count. A second count is produced that is proportional to the scanned path within the current scan line.. Determining the angle between scan line and centre axis avoids error in reading the marker lines.

Title: Wood fibre suspension collecting trough for grinding machine - hangs by flange bolts from housing without loading foundations
Inventor: HAIKKALA PEKKA
IPC: D21B1/24
Filed: 1980-06-06
Abstract: In a plant for grinding wood, esp. for papermaking, by means of a rotating grindstone, whilst water is fed in, the collecting trough for the suspension of fibre, partly limits the grinding chamber which may be under the pressure of a gas, and is self-supporting on the grinder housing. For pref. the trough is fixed to and hangs from the grinder housing; being bolted to the flange beneath the housing by screws through its upper rim. The joint is airtight. Used to collect the slurry behind a dam, the height of which can be adjusted before it flows to the next processing stage. The immersion of the grindstone can be varied from 2 to 10 cm so that it is cooled, lubricated and cleaned. The hanging of the trough eliminates the very heavy loading on the foundations caused by the pressure in the housing; the trough is adequately strong to stand up to all the requirements.
