Title: Slope-triggered five-bit one-from-four selection shift register - is designed as current mode logic with temporarily storable output signal
Inventor: MILLER HOMER W
IPC: G11C19/28
Filed: 1979-01-26
Abstract: The resettable shift register contains a clock part, a control part and numerous data stages. Each data stage consists of an input part, a master/slave latch part and a temporary-storage output part. Each data stage can connect the output of the latch part to the input part of the next data stage and connect the latch part's output of the input of the temporary-storage output part.

Title: Capacitor foil edge trimmer - with profiled slot for annular lower blade in revolving mount
Inventor: NEUWALD ANSELM DIPL PHYS
IPC: H01G13/00
Filed: 1979-01-26
Abstract: A cutting device for the continuous edge trimming of a plastic foil, for example of foils needed for the mfr. of capacitors, consists of a rotating upper (circular) cutter blade which slightly overlaps the cutting edge of a rotating lower (ring-shaped) cutter blade. The latter is fastened to the side of an annular slot in a two-part cutter ring boss. The slot is just wide enough to allow the upper blade to be swung out of it wideways. It then becomes narrower within the tolerance limits of the lower blade and is finally enlarged enough to accept the clamp ring for the lower blade. This allows the trimmed edges to be reduced to a min. so that the wastage of foil material is reduced.

Title: Paddle wheel for fluid flowmeter - is made of light plastics with metallic attachments and has average specific weight similar to that of water
Inventor: WINDHAB WILHELM
IPC: G01F1/06
Filed: 1979-02-02
Abstract: The paddle wheel comprises a rotationally symmetrical arrangement of blades (1) mounted on a central axle (2) terminating in a metallic spigot (3) which is concentric with a screw member (4) which acts as a drive. The bulk of the paddle wheel is made from plastics material with a specific weight just under 1 gm/cc., so that with the metallic attachments, including metallic blade retaining bolts (5), it has an average specific weight of about 1 gm/cc. so that in water or liquid of a similar density it is virtually weightless and therefore places a negligible load on the bearing.

Title: Mask applicator for metal and polymer laminates - displacing and lifting mask by cam mechanisms
Inventor: BEHN REINHARD DIPL PHYS
IPC: H01G13/00
Filed: 1979-03-13
Abstract: Alternate layers of metal and of glow discharge polymers with an offset relative to each other are applied to a substrate in the manufacture of electrical capacitors on a drum with recesses for the substrate holders. Two stationary cam rings enclose the two drum ends. A spring loaded plunger on the drum runs along a groove in the first ring and is linked through a ratchet wheel and cam to displace the substrate holder. Other pins run in grooves of the second ring and lift up a mask when the substrate holder is being displaced between a metallisation section and a polymerisation section. This is a simple method of placing the masks relative to the substrates in their proper positions and to reproduce these operations with a high accuracy.

Title: Solar heating system using roof tiles - has overlapping tiles with metal underlayer resting on correspondingly shaped heat collector pipes
Inventor: RITTER ALFRED DIPL CHEM DR
IPC: E04D13/18
Filed: 1979-04-27
Abstract: The solar heating system using roof tiles (10), uses tiles which can be made of clay material, each carrying a metal layer (11) in contact with a pipe (12) for circulating a heat collector fluid. The tiles overlap, and the pipe is stepped accordingly. Seen from above, the pipe can also be zig-zag shaped. The underside of the tile can incorporate grooves to allow air to circulate underneath and the grooves can be square, round or triangular in section. Alternatively the tiles may be ribbed underneath. They may also incorporate square section grooves to fit over the roof surface. The material from which the tiles are made may include additions to improve heat conductivity.

Inventor: WIEDENROTH BERND
IPC: G11B23/00
Filed: 1979-07-20
Abstract: A magnetic tape recording system employs dynamic compression and/or expansion in a switching mode to reduce the premagnetising current to a minimum level. The input signal is either transmitted directly or over a compression stage (2) to an amplifier (4) containing two two frequency dependent stages (6,7) that are selectively switched (8) to supply an input to the recording head (9). Replay (10) is over an amplifier (12) with a frequency dependent stage, coupled to an expander (17) with switching stage. Premagnetising current is provided by an oscillator (13) over one of two switched (15) paths of differing resistance. The switches are coupled such that the premagnetising is minimised.

Title: Optical scanner using rotating mirror - has narrow cylindrical surface on rotor and equally-spaced flat facets
Inventor: RUNCIMAN HERBERT MORRISON
IPC: G06K7/10
Filed: 1980-06-14
Abstract: The optical scanning device uses a rotating mirror (14). At the bottom of the mirror assembly there is a narrow cylindrical reflecting surface. Above this narrow reflecting surface there is a polygonal body which may have 6 flat sides or a larger number, eg. 12 flat sides. The light (10a) from a source of parallel light passes through a lens (11) which focusses it (12) onto the narrow mirror (13). Diverging light (10c) leaving the narrow mirror falls on a concave mirror (16). The focal length of this mirror is chosen to give a parallel beam (10d) which falls on the flat facets (17) of the polygonal mirror. As the mirror assembly (14) rotates, a series of beams scanning in one direction is produced.

IPC: G21C19/317
Filed: 1980-09-17
Abstract: A nuclear power plant is surrounded by a safety containment in which a recombination appts. carries out controlled oxidn. of free hydrogen to prevent excess build-up of hydrogen, esp. in a fault case. Vertical shafts inside the safety containment extend over at least half the height of the containment and comprise heaters for producing a convective circulation of gas.

Used for any reactor system where hydrogen can be produced by radiolysis of water in the core in the case of loss of coolant, or in the sump of the cooling pool. The arrangement enables full circulation to be maintained inside the containment without mechanical pumps and similar devices and thus prevents local build-up of hydrogen above the safety level of approx. 4% by vol.
