Title: Method for the digital transmission of television images
Inventor: REIMANN UDO DIPL ING
IPC: H04N19/60
Filed: 1982-10-29
Abstract: A method for the digital transmission of television images, in which in each case digitised signal values of a field are converted into spectral values with the aid of a transformation (for example an M transformation), which values are quantised and are sent out after data reduction. The arithmetic mean of the signal values is calculated for each field and transmitted separately. Since this is an M transformation free of mean values, it is calculated from the remaining quantised spectral values. The original signal values, apart from a quantising error, are reconstructed by adding the inversely transformed spectral values and the associated mean value. <IMAGE>

Patent DE-3330302-A1 (DE)
Title: Component
Inventor: BECKER OTTO ALFRED DR
IPC: E04B1/80
Filed: 1983-08-23
Abstract: The invention relates to a component consisting of a hollow body, which can be sealed air-tight and vapour-tight by walls and rigid or flexible sealing bodies, for the purpose of using propellants (or heating gases) of high detonating violence, for example hydrogen and oxygen, whose explosive forces are regulated as required by the addition of chemically unreactive materials, for example nitrogen. According to the invention, the required hydrogen is released from a catalytic bonding (for example in magnesium hydroxide) by heat and introduced in predetermined units into the explosion chamber, for example by means of a roller with transverse bores. The rate of the gases can here be selectively altered by means of switches, levers, pedals or the like. The storage elements reversibly loaded with propellant (for example hydrogen) are passed by means of transport belts to a heat chamber and "discharged" therein. This propellant is then fed to the explosion chamber.

Title: Electronically controlled fuel control device for a combustion engine
Inventor: FUJIMORI KYOICHI
IPC: F02D41/40
Filed: 1983-11-30
Abstract: In the case of an electronically controlled fuel control device for a combustion engine the fuel quantity is to be easily controllable at any time with a high degree of accuracy. To this end a reference signal is first generated in the electronically controlled fuel control device, which signal indicates the fuel quantity which is injected according to the operating state of the internal combustion engine; an actual quantity signal is then generated which indicates the quantity of fuel which is injected by means of a fuel injection pump. By means of a device responding to the reference and actual quantity signals a first signal is then generated by means of which the actual fuel quantity is made to conform to the required injected fuel quantity. Finally by means of a device responding to a position signal and the first signal a second signal is generated by means of which a fuel adjusting element at the position determined by the first signal is brought into the correct position.

Title: Method and device for grinding toothed racks on universal thread-grinding machines
Inventor: DAEMMRICH ERHARD
IPC: B23F23/06
Filed: 1984-03-02
Abstract: The invention relates to a method and a device for grinding toothed racks and can be used on universal thread-grinding and worm-grinding machines. The object of the invention is to grind toothed racks with high productivity while utilising the typical functions of a universal thread-grinding machine. The toothed racks to be ground are arranged on tangential mounting surfaces of a cylindrical clamping device, the contact radii of which enclose identical centre angles. The clamping device is mounted between the centres and set in rotation by the work spindle. A grinding body is advanced by the projection of a grinding slide, and a straight line is produced above each mounting surface by a relieving stroke running from 0 via maximum to 0. After a preselectable number of revolutions of the work spindle, the grinding slide rebounds and the axial feed of the work slide is effected by an indexing amount corresponding to the width of the tooth profile. Several toothed racks are ground simultaneously on the clamping device, in which arrangement several toothed racks (including helical toothed racks) can also be clamped per mounting surface. <IMAGE>

This results in the advantage that the entire stop device does not need to be rotated during the machining, but only a hinged stop needs to be swung in or out.
Patent DE-3422376-A1 (DE)
Title: Choke valve
Inventor: BRUNNER RUDOLF
IPC: F16K47/04
Filed: 1984-06-15
Abstract: The invention relates to a choke valve, in particular for high-pressure hydraulics, having a housing and a choke passage which connects the inflow side to the outflow side and in which an adjustable choke member engages and forms at least one pressure-reduction stage. With such choke valves, undesirable operating noise occurs in the high-pressure hydraulic system under certain operating states on account of high pressure and high delivery capacity. According to the invention, this is avoided by the choke member forming two pressure-reduction stages in the choke passage so that only a portion of the total pressure to be reduced is reduced in each pressure-reduction stage and thus the generation of noise is reduced.

Title: Process and apparatus for the subsequent filling of existing cellars, tunnels and the like with concrete
Inventor: BERG DIETRICH VON
IPC: E04G23/02
Filed: 1984-06-20
Abstract: The invention relates to a process for the subsequent filling of existing cellars, tunnels and the like with concrete by means of a closed shuttering, using high-workability (poured) concrete or pumped concrete. In order to permit good sealing which can be monitored, of the upper wall parts and the ceiling reinforcement, the invention proposes that, first of all, a reinforced-concrete slab be cast in place on the existing floor. Thereafter a concrete casting is fitted on the front vertical walls by means of shuttering elements or pre-fabricated reinforced-concrete parts. In this arrangement, the shuttering elements are held by fastening means which have been introduced into the vertical walls beforehand. On a scaffold, a ceiling shuttering is then fitted at a distance from the existing ceiling. After this, the high-workability (poured) concrete or pumped concrete is introduced through one or more bores in the existing ceiling or through pipelines in the shuttering. Finally, the ceiling shuttering is pushed or drawn upwards towards the existing ceiling by hydraulic or pneumatic means. The invention is applied, for example, when it is necessary to convert the existing cellars into shelters. In this arrangement, the subsequent reinforcement of the existing ceiling of such a cellar or tunnel is of particular importance. Good sealing which can also be monitored is achieved by the process according to the invention. The pressure on the concrete can, for example, be ... until ... Original abstract incomplete.
