Patent DE-2709825-A1 (DE)
Title: Hand operated pocket cigarette making machine - has swinging arm for locating paper tube inside tobacco to reduce carbon mon:oxide
Inventor: SEEGER WOLFGANG
IPC: A24D1/00
Filed: 1977-03-07
Abstract: The hand operated pocket cigarette making machine which has a trough into which loose tobacco is distributed, and which has a compression plate on top, which is swung down to consolidate the tobacco, also incorporates a system for enclosing a small diameter paper tube down the middle of the tobacco. This tube forms a channel for air to pass through the tobacco as the cigarette is smoked, so as to reduce the carbon monoxide content of the smoke. Under the compression plate (37) is a spindle (101) onto which the paper tube is slid, and the spindle swings down when the plate is swung down, after inserting the tobacco. The plate and the spindle are drawn back, leaving the paper tube in position after the cigarette has been made.

Title: Activated sludge system of sewage treatment - with high-duty basin between buffer basin and oxidation trench
Inventor: SCHNITZLER ERWIN F DR ING
IPC: C02F3/12
Filed: 1977-05-14
Abstract: A sewage treatment system based on the activated sludge principle consisting of a buffer basin with an aerator, an oxidation trench with an aerator, and a final clarification basin has been modified in order to avoid the troublesome production of excess sludge. A high-duty basin with an extra aerator is now arranged between buffer basin and oxidation trench. The sludge recycling from the final clarification basin is now directed in the high-duty basin where a fine distributor is situated for the recycled sludge, and a fine distributor for the run-off from the buffer basin.

Title: Welding together thermoplastic profiles - one profile is pressed down to same height as other during welding process
Inventor: URBAN JOSEF
IPC: B29C65/20
Filed: 1977-07-29
Abstract: Welding equipment for thermoplastic profiled sections produces window frames or similar by heating them, and pressing them together until the softened materials merge together, the machines having >=1 slide on the frame and devices to clamp the sections on the slide or frame. At least one press acts downwards onto the softened area of at least one section, it presses it at right angles to the movement of the equipment, and down to the size of the other section. Overcomes the problem of tolerances in the section dimensions i.e. eliminates stepped joints and therefore any need for subsequent processing, because one section is pressed to the dimensions of the other during welding.

Title: Electronic circuit for controlling model railway - decides which train travels over single track section and which trains must wait using blocking flip=flops
Inventor: HOETZSCH FRIEDRICH
IPC: A63H19/24
Filed: 1978-02-15
Abstract: A model railway has a main loop of single track line on which trains can travel in either direction. There is a short length of double track with one track for each direction of travel. In addition, there is a section of three parallel tracks on which trains can travel in either direction. Switches placed on the track transmit signals to an electronic control circuit which determines which trains can travel and which trains must wait on the double or treble section. The circuit can deal with several trains and can be easily expanded to handle extra trains.

Title: Multi-satellite intrusion alarm control system - has master unit connected to satellite by only four conductors to enable analysis of cause of alarm
Inventor: HUMPHRIES PETER
IPC: G08B25/01
Filed: 1978-02-28
Abstract: An intrusion alarm system has satellites connected to a master by an unshielded cable having only four conductors namely two power conductors, a drive signal conductor, and an alarm conductor. When an intrusion is detected by a satellite, its control circuit transmits a high level alarm signal to the master and also enables a speaker in the satellite. The master has a rocker switch which an investigator turns off when he arrives at the supervised premises. This turns off the drive signal to the satellite. The control circuit of the satellite that caused the alarm responds by sounding its speaker, enabling determination of where the alarm occurred.
Patent DE-2821063-A1 (DE)
Title: Pseudo-noise radar system - employs bi-phase and amplitude modulation with multiplicative mixer to improve attenuation characteristics
Inventor: VALDES SERGIO FLORENCIO
IPC: G01S13/32
Filed: 1978-05-13
Abstract: In a pseudo-noise radar system a maximal length binary pulse code of amplitude zero or A amplitude modulates a carrier wave and reverses its phase 180 degrees in synchronism. Either the amplitude modulated or phase reversed wave is transmitted. The received wave is passed through a multiplicative mixer that receives the other wave as an input. The mixer output is effectively (L + 1)/2 when correlated and effectively zero when phase shifted one bit to one bit less than a word, L being the word length. Signals not correlated are attenuated straight. The radar system may be used with conventional equipment for fire control, missile range and/or velocity tracking.

Title: Electro-cardiograph and vector-cardiograph teaching unit - has box with two perpendicular mirrors and loop mounted in between, and orthogonal sagittal plane mirror
Inventor: BENJO CEZAR
IPC: G09B23/28
Filed: 1978-06-09
Abstract: The apparatus for teaching electro-cardiography and vector-cardiography comprises a portable box having a first mirror attached to the inside of the lid so as to be normal to the first mirror when the lid is open. The two mirrors are marked to indicate the electrode leads on a patient in the horizontal and frontal planes, respectively. Between the mirrors is a loop-mounting device for mounting in between one of a series of vector-cardiograph loops representative of normal and pathological heart conditions. Orthogonal projections of any particular loop are reflected by the mirrors and such reflections can be used to assist in teaching electro-cardiography. A third Sagittal plane mirror may also be mounted, when the box is open, in orthogonal relation to the two mirrors for the teaching of vector-cardiography.

Title: Current conductor rail support - cut from L=shaped GFR plastic
Inventor: WEINERT MANFRED DR
IPC: B60M1/30
Filed: 1978-08-16
Abstract: Supports to carry current conducting rails or sleepers of a track are produced from L-shaped angles, made in lengths of several metres from a GFR plastic, using e.g. unsatd. polyester or epoxy resins as the binding agent. Straight parallel cuts along the flange and oblique cuts along the web divide a length into cantilever supports, which receive on the flange elongated holes for fixing to the sleeper, and on top of the web a profiled cut-out and clamp for the rail foot. The surfaces are protected by a high-resin fibre mat. This provides better corrosion protection than metal supports and can be produced at low cost.

Title: Plastic filter casing - mfd. including shunt damping spaces in two parts by blow moulding
Inventor: LENZEN DITRICH DIPL ING
IPC: F02M35/024
Filed: 1978-11-07
Abstract: Filter casings, e.g. for the air intake of internal combustion engines, are produced form plastics by a blow moulding process in two parts. One for the housing includes an annular shunt damping space below the space for the inserted filter element and a short pipe extension; the other for the lid includes in the centre of cylindrical damping space. But parts are produced by laying an inflated hose between a two-piece mould. Some parts, requiring an undercut, are thereby produced with a double foil thickness. All holes, such as for access to the damping spaces and the pipe extension are drilled subsequently by mechanical means. This simplifies the mfr. of plastic filter casings of even complex shape and saves the subsequently attachment of partitions. Only two blow moulding operations are required.

Title: Control programme test unit for microprocessor - has comparator stage to check validity of selected locations in erasable PROM
Inventor: HUWALD GERHARD DIPL ING
IPC: G06F11/36
Filed: 1979-02-17
Abstract: A microprocessor system operates together with a programme test facility based upon stops located within an erasable programmable read only memory (EPROM). A microprocessor control unit (1') is coupled over an address bus (3), data bus (5) and control bus (4) with an EPROM (6) holding the control programme and test unit (9). An interrupt unit (7) handles requests from external devices (8). The test unit receives the addresses and stores a value in a register when a decoder identifies a stop instruction continued in the control programme. Whe a stop does occur the register state is compared with the value stored and a proceed instruction is initiated. If the comparison is not satisfactory, an error is indicated.
