Title: Predistortion and level setting circuit for colour TV - produces staircase waveform for scanning colour film and diapositives
Inventor: FUNKE DIETRICH
IPC: H04N9/11
Filed: 1975-06-13
Abstract: The pre-distortion and level setting circuit for colour television amplifiers used in film & colour slide scanning consists of a converter in which the line scan pulses are transformed to 13 mu sec duration pulses. One output of the transformer is connected to a monostable producing 40 mu sec squarewave pulses and to an as table multivibrator. The two outputs of the multivibrator are connected to a shift-register operating as a serial-to-parallel converter. The five outputs of the converter pass to a diode matrix to produce a staircase waveform of 7.5(+-)0.5 mu sec step width. The output amplifier provides the required signal to drive the input stage of the film scanning equipment.

Title: Adjustable air circulation regulator for inserted vent - has cylindrical vent body with adjustable flare and domed cover plate
Inventor: KEIDERLING GEORG
IPC: F21V37/02
Filed: 1975-07-10
Abstract: Air flow circulation regulator for inserted vents has a domed cover held on a conical flared part of the vent top. The domed roof directs the wind upwards and the funnel shaped flare directs the air and wind flow downwards so that the upwards circulation is promoted within the vent tube for protecting the candle flame. The domed cover (a) and the flared end (b) hence split the wind flow stream and no wind in able to blow directly into the vent. The domed cover plate height can be adjusted relative to the vent housing. Adjustment is possible by the threaded spindle (c) which connects the domed plate to the central support spider at the top of the vent. The flared end (b) is pressed in its manufacture so that it has ribs for holding purposes.

Title: Contact welding of plastic components - with supports for components suspended in spherical bearings
Inventor: GAUCHEL MANFRED
IPC: B29C65/00
Filed: 1976-04-02
Abstract: Contact welding of the plastic components is performed with the supports for the plastic components suspended in spherical bearings, and pref. with heating up of the components by a heat reflector. The surfaces to be welded together may be pressed simultaneously against the heating element and against each other, so as to obtain uniform specific pressure over the whole welding surface. The structure of the whole appts. is simplified, as the elements for aligning the components tobe welded can be eliminated. A shorter cycle time and easier manipulation are allowed, with automatic equalisation of mfg. non-uniformities, and with a weld seam of improved quality.

Title: Hinged toe clamping arms on safety ski binding - are attached to leaf spring mounting plate to break free under excessive load
Inventor: SCHMIDT JOHANN
IPC: A63C9/085
Filed: 1976-09-30
Abstract: A safety ski binding includes a toe clamp assembly which is mounted on the ski (13) by means of a flat leaf spring (10). Two vertical studs (6, 7) provide pivots for two levers (4, 5) which are located side by side on the leaf spring (10). Each lever is also equipped with a hinged clamp arm (9) which when in their normal position, overlap the corners of the ski boot sole (16). When due to excessive load on the ski boot, its sole tilts away from the ski surface, the leaf spring (10) is lifted together with the clamping head assembly. This movement causes the hinged clamp arms (9) to free the ski boot sole and thus releasing the boot from the ski.

Title: Standard drying frame for different roof tiles - has four holding levels for different tile shape drying
Inventor: LUDOWICI MICHAEL CHRISTIAN
IPC: F26B25/18
Filed: 1977-02-14
Abstract: The standard drying frame is used for accommodating different form components for different roof tile models. The frame takes into account the fact that each individual roof tile model has a certain number of moulded pieces such as gable end tiles, gutter edge tiles, gabled roof closing tiles, roof ridge closing tiles, ventilating tiles and snow catching tiles. The standard drying frame is used for different form pieces so that these can be dried and made on the standard drying frame. The tile mounting side has basically four holding levels. The difference between the lowest and the highest level is formed so that the furthest outward projecting form piece component can be accommodated. The middle field of the tile mounting side has several transverse members. One of the outside support longitudinal profiles (31) has an opening (312). This opening continues also into the middle field longitudinal profiles.

Title: Optical telecommunications cable containing several fibres - lying parallel and without stranding inside sheath and cushioning protecting against mechanical damage
Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1977-06-24
Abstract: The optical telecommunication cable has a plastic sleeve (1) approximately 1 mm in diameter, for example, consisting of polypropylene, polystyrene or polyamide, and containing two glass fibres (2) parallel to one another.

Title: Rotary tabletting machine with hydraulic pressure regulation - coupled to check valve and damper regulating quantity of tablet charge
Inventor: GOLOSKOV EMMANUIL ISAAKOVITSCH
IPC: B30B11/08
Filed: 1978-02-14
Abstract: A table letting machine comprises a rotor with vertical press tools enclosing a charge of powder. The rotor carries the tools between pressure rolls - which compact the powder to form a tablet. The pressure on one of the rolls is stabilised by a hydraulic system including a regulator. Hydraulic fluid in the stabiliser passes through a check valve and damper with capillary bleed to average out the force applied to the tablet rolls. An increase in this pressure above a predetermined value causes an adjustment to be made to the powder charge loaded. The appts. makes tablets e.g. of medicines or catalysts. The appts. provides a constant tablet mass.
