Patent DE-2520458-A1 (DE)
Title: Colour balancing circuit for video signals - uses zero point suppression of one colour difference signal for both NTSC and PAL-SECAM
Inventor: KOUBEK MICHAEL
IPC: H04N9/77
Filed: 1975-05-07
Abstract: The colour balancing circuit, for video signals, suppresses colour imbalance by suppressing the zero point of at least one of the colour difference signals. Suppression is performed on that colour difference signal containing the colour which has the largest colour imbalance, and also for this colour's complement, i.e. that colour that occurs least (gren and deep red). For an NTSC system a matrix is coupled after the RGY output of the single-tube camera and gives the I and Q difference signals. Either the Q signal alone or both the I and Q signals are subjected to zero point suppression. For a PAL/SECAM system, a second matrix is included after zero point suppression to give the r-Y and B-Y signals.

Title: Windowsill or other wall top fitting fixture - with edge fillets in sealing bricks forming channel for cemented anchor ends
Inventor: HACK GUENTER
IPC: E04D13/14
Filed: 1975-08-25
Abstract: The top edge of the wall (1) is given a row of sealing bricks (2), and these form a gutter running along the wall, with undercut sidewalls, by means of fillets (3, 4) along at least one of their edges. The anchor-shaped ends (7) of the fittings (6), or substructures supporting these, are inlaid in the gutter, and mortared or concreted into position there. The anchor-shaped ends, or substructures, may be in the form of perforated sheet metal strips; the supporting substructure may consist of brackets, or it may be a shaped rail running to the gutter. The process is for the attachment of fittings, such as window sills, window frames, radiators, electrical services, roof coverings, or others, at the top edges of the walls in a building. They can be fitted without impeding each other in anyway, avoiding the need for improvisation or the risk of damage to the building.

Title: Camera flashbulb socket cover - is hinged to open wide and becomes detached if opened too far to avoid breakage
Inventor: SIMON HORST
IPC: G03B17/12
Filed: 1975-10-07
Abstract: The cover (12) is hinged (13) to lie flat over the camera flashbulb socket (14), to keep out the dust when the socket is not in use. It opens to a little beyond the vertical, and is held open or closed by a spring (20), which presses against suitably profiled surfaces (22, 23) near the hinge. The hinge socket is open at one side, and there is room (19) for it to come loose from the hinge pin, if the cover is opened too far. An alternative form of the hinge socket has a complete circumference, but only at the extreme ends of the hinge pin, which itself tapers at the ends. The material is elastic enough to bend and come free from the ends of the hinge pin, if necessary.

Title: Sliding door with transverse and parallel movements - has eccentric for adjusting door pressure on door frame seals
Inventor: WEIKERT RUDOLF
IPC: E05F11/14
Filed: 1976-07-24

Patent DE-2637715-A1 (DE)
Inventor: LAEMMLE HERBERT ING GRAD
IPC: F16B4/00
Filed: 1976-08-21
Abstract: The spindle has a bearing housing (1), into which is inserted a sleeve (9) containing a neck bearing (7) and a foot bearing (8) for the spindle shank (12). The sleeve (9) has at the top a mounting (6) with a conically narrowing seat surface (5) which, after being pressed into the bearing housing (1), bears against a counter-seat surface (4) of the latter. At least one of the seat surfaces, for example the seat surface of the mounting (6), has continuous grooves. The webs present between the grooves are consequently deformed during the pressing-in operation. This design requires less precision in the production of the seat surfaces (4, 5) and thereby reduces the production costs. <IMAGE>

Title: Electronic tachometer voltage generation - involves bipolar keying ratio controller to supply motor with current
Inventor: PAUL HEINZ
IPC: H02P7/29
Filed: 1976-09-06
Abstract: The two times of the pulse generator are adaptable to the requirements of the motor-tachometer circuit, so that optimum control ratios can be obtained. In the transition from one time to the other prolonged blocking is carred out to keep away the cut-off flank in the tachometer signal. An electronic overload protection is used to limit the current of the control element or motor by reducing the modulation of the keying-ratio controller. Reversing operations can be undertaken without restriction, while the overload protection is maintained during lengthy blocking.

Title: Catalyst performance monitor for IC engine exhaust afterburners - uses changes in internal temp. relationships from two sensors
Inventor: WOESSNER GUENTER DIPL ING DR D
IPC: F01N13/02
Filed: 1976-09-29
Abstract: The catalyst performance monitor uses a signals from two temp. sensors, pref. standard commercial NTC resistances. Catalyst exhaustion causes changes in relationship between the signals. When these reach a predetermined value a warning is issued. Sensors may be identical or one may be coated with catalysts. In the former case one is fitted in the entry chamber, the other in the reaction zone. In the latter both are together, in the reaction zone or (pref.) in the outlet chamber. With the former arrangement a cut-out for the signal during engine warm-up is required.

Title: Testing for allergic reactions deep in respiratory track - using allergens in dilute aerosol fed into air flow at selected places
Inventor: BISA KARL DR MED
IPC: A61B5/08
Filed: 1976-10-29
Abstract: The air the patient is to breathe is prepared in a long tube which has several selectively-controlled valves in its length. THe suspected allergen is injected into the tube through a chosen valve at the moment between the patient's expiration and inspiration, when the air column is still. When the air comes to rest again, when the next inspiration is complete, the allergen will have reached a definite position deep in the respiratory tract. There is provision for measuring the patient's response for diluting the allergen evenly, for flushing any residue away before the next test and for counteracting the allergen with a desensitiser when a positive response is found.

Title: Ring spinning monitor - which tests for winding irregularities during short time spans
Inventor: ROHNER JOACHIM
IPC: D01H13/18
Filed: 1977-01-24
Abstract: Ring spinning machine with a drawing unit, includes a slubbing removal and/or clamp unit (I) which is controlled or operated at the drawing-in rollers through a unit which establishes any irregularity in the winding at the rotating components of the whole drawing unit. Design reduces the amt. of monitoring required but delivers a rapid indication of any winding irregularity during drawing. This allows the use of a mobile monitor to determine the behaviour, in short time spans, to reduce total monitoring time.
