Patent DE-1807929-B2 (DE)
Title: Firearm double belt feeder with remote control - has symmetrical feeder sprockets actuated by breech block reciprocating movement
IPC: F41A9/37
Filed: 1968-11-08
Abstract: The ammunition guide is used in an automatic firearm for remote controlled optional firing of two different types of ammunition. The cartridges are pushed into the cartridge chamber by a breech block which also removes empty cases in a longitudinal direction by a reciprocating movement. The linear reciprocating movement of breech block is transformed into reciprocating rotation for the feeder sprockets in opposite direction. The breech block actuated ejectors move cartridges from the belt for firing. The two sprocket shafts have additional sprocket wheels. The cartridge in the preparation position is guided into these sprockets and is moved into the loading position by the rotation of a given sprocket shaft.

Title: Holder with shank for cutting insert - is held on slide and has adjusting wedge for insert height
IPC: B23B29/04
Filed: 1969-06-24
Abstract: The tool holder for the cutting insert as in the main patent has a shank which is fastened directly on the cutting tool slide by an arm at right angles to the tool shank. This arm is clamped against the slide end face and the shank is held in position by keys and bolts.

Title: Adaptive equaliser for telephone networks - is made adaptive by converting weighting circuits into multipliers receiving distortion-dependent inputs
IPC: H04L25/03
Filed: 1970-08-12
Abstract: The adaptive equaliser is as in 1791174 but is extended here to adjust automatically to varying distortion. The equaliser adapts to variations in the transmission properties of the telephone network arising both from time changes and from sudden changes caused by switching. The weighting circuits as in 1791174 are constructed as multipliers that multiply the output of one stage of the shift register with the output of an auxiliary circuit responding to changes in distortion. The auxiliary circuit consists of a subtractor, forming the difference between the unadapted signal and an earlier reference, and there is a multiplier and an integrator.
Patent DE-2108807-B2 (DE)
Title: Regulating control for HV DC transformer - operated with coded signals complement computation for control signal sign derivation
IPC: H02J3/38
Filed: 1971-02-12
Abstract: Synchronous control of circuit breakers for transformers connected to asynchronously or synchronously operating bus bars of h.v. d.c. transmission copes with changes of voltage. The position of tap changers is monitored by coded signals fed to an adder for comparing the current value with the set level. The comparison is carried out by subtraction following the complement computation. This provides a sign signal for up or down setting of tap changers or for stopping the control operation when signals are of equal value. The h.v. d.c. transmission includes rectifier bridges (1-8) feeding busbars (9, 10) while the midpoint is earthed (13). The bridges are connected to lines (17-19) by single phase transformers (14-16) fitted with circuit breakers. The encoders for switching setting are combined to reduce the number of data lines while the complement computation provides a sign signal for high or low control signal deviation.

Title: Housing for transformer substations - has collapsible wall of thermoplastic material between switchgear section and transformer
IPC: H02B7/06
Filed: 1971-09-18
Abstract: An enclosure for transformer substations for use in urban areas, where the sudden release of hot gases due to a switchgear fault could cause injury. A barrier (6) between the switchgear section (2) and that containing the transformer (3) is made of thermoplastic material, and provided with breaking and bending lines. These are arranged such that if an explosion occurs the barrier sections (9a, 10a, 10b) bend and break towards the transformer (4) and direct the hot gases onto the latter. By passing over the mass of the transformer before escaping out of the station vents, the gases are sufficiently cooled so that no injury to persons outside results.

Patent DE-2260611-B2 (DE)
Title: Forming protective layers on glass panes - to prevent scratching during storage and comprising strings of solidified plastics or wax
IPC: B05D1/30
Filed: 1972-12-12
Abstract: Glass panes are provided with cord-shaped intermediate layers by allowing a stream of liq. plastic to fall at least intermittently onto a pane on which the plastic solidifies or hardens. The plastic is either a meltable adhesive contg. paraffin wax or other non-polar cpds.; or a two-component foamable plastic. The glass panes pref. move along a conveyor underneath a vessel heated to a controlled temp. and contg. bottom outlet holes through which streams of the plastic flow via shutter valves controlled by magnets. The leading edge of each pane triggers a switch so the valves open, whereas the back edge of each pane causes the valves to close. Arrangement is used for stacking glass panes, where the layers prevent direct contact between the panes and thus obviate scratches on the surface of the glass. The deposited plastic remains on the panes even when the latter are tilted to a vertical position.

IPC: B05C1/08
Filed: 1982-03-23
Abstract: A web of crepe paper, thin plastic foil or like material convoluted into a roll has an outer side which is provided with a continuous coat of adhesive. Transversely extending, uniformly spaced weakened portion in the form of perforations or slits are formed in the web, and layers of a material which does not adhere to the adhesive are applied to the web. Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions. The roll can be used for the cleaning of garments or for analogous purposes and can be made in an apparatus wherein the application of layers of non-adherent material precedes or follows the making of weakened portions. The length of each layer, as considered in the longitudinal direction of the web, is a small fraction, preferably less than one-third, of the distance between two neighboring weakened portions.

Abstract: A pix-in-pix display includes a filtering system for processing the video signals which produce the reduced-size image. The filtering system includes an anti-aliasing filter - (210) which reduces the amplitude of the components of the video signals which may cause aliasing distortion when the image is subsampled.
