Title: Silently height adjustable blackboard without canting - has guide rail with inclined guide faces engaged by rollers
Inventor: SCHAFFITZEL HERMANN
IPC: A47B97/06
Filed: 1980-06-28
Abstract: The blackboard can be displaced parallel to the support frame by a guide comprising at least one guide rail (3) which is associated with the support frame (1) or board face (2) and has on oppositely aligned sides guide faces (12a,12b) which are inclined by an angle beta other than 90 deg. to the board face. Rollers (4) or other guide elements are set locally fixed on the support frame 1 to form an angle beta of 45 deg. to the board face (2) and engage on the guide faces (12a,12b). The forces which arise on the board as it is displaced can now be compensated so that there is no danger of the board canting. Furthermore the forces which occur when the wings of the board are folded at right angles to the plane of the board do not impair the displacement of the board.

Patent DE-3031250-A1 (DE)
Inventor: JANSSEN HERRMANN-JOSEF
IPC: F23D14/38
Filed: 1980-08-19
Abstract: Regulation of liquid gas to be burnt has hitherto been pressure-dependent. The maximum pump pressure is limited such that a regulation of only about 1 : 1.5 is achieved. From now on, rate regulation in the region of about 1 : 8 will be carried out using a control bush (9) and control piston (6). The space (14) to be permeated by the liquid gas in front of its outlet nozzle (11, 12) may only be expanded by the control piston (6) to the extent that any associated drop in the pressure of the liquid gas does not lead to premature gasification. A front projection (13) on the control piston (6) ensures that such an increase in volume only occurs when the quantity of liquid gas increases, so that the fuel pressure of the liquid gas in front of the first outlet nozzle (11, 12) is always greater than the gasification pressure of the liquid gas, i.e. never falls below it. <IMAGE>

Title: Fire-self-extinguishing, non-flammable, sound-proofing and heat-insulating foam mat, especially for motor vehicles with internal combustion engines
Inventor: SCHMALZ REINHOLD
IPC: A62C99/00
Filed: 1981-02-11
Abstract: Extinguishing means are included in the aforementioned foam mat which emerge in the event of a fire as a result of the foam melting at the point of the fire and smother and/or extinguish the flames. The foam mat is also suitable for sound-proofing and heat insulation. The foam mat can, depending on the nature of the engine compartment of the motor vehicle, be fastened to the inside of the bonnet of the latter or be placed directly above the engine, and fixed in place by closing the bonnet. In the case of some motor vehicles, it may be necessary to protect the foam mat against contact with the exhaust system and/or the belt drives. The foam mat mounted above the engine of a motor vehicle is intended to protect people against burning, absorb noise and furthermore accelerate warming up of the engine and/or make it possible without greatly loading the engine in the cold part of the year, thereby reducing the specific fuel consumption of the engine, the harmful concentration of exhaust gases and wear of the engine. It is advantageous for it to be possible to remove the foam mat from the engine compartment quickly and easily, so that it can be used as an extinguishing blanket or as a support in emergencies.
Patent DE-3105663-A1 (DE)
Title: Device for locating error sources and use of the device
Inventor: WEISS JUERG DIPL ING
IPC: H04B17/40
Filed: 1981-02-17
Abstract: A device is indicated for locating error sources in a transmission path for duplex transmission of digital signals. Each signal regenerator (18) has an error detector for each transmission direction which closes a switching contact (39) when a specific error rate is exceeded. The input pole of an assigned voltage generator (27) is thereby connected via a diode (41) to earth (50). Central feed current is supplied by a current source (45) to which all the voltage generators (27) are connected in series. The loop formed in this way represents a floating circuit which is earthed on one pole (46) of the current source (45) via a high-impedance resistor (48). A voltmeter (49) measures the voltage drop on this resistor, which is zero if there are no errors present. When errors occur, the loop is earthed at a different point by closing one or more of the aforementioned switching contacts (39), whereby the voltmeter (49) then indicates a voltage. The level of the voltage is dependent on where the error occurs and thus indicates the error location. <IMAGE>

Title: Location-addressed associative memory
Inventor: TAVANGARIAN DJAMSHID DR ING
IPC: G11C15/04
Filed: 1981-12-24
Abstract: The invention relates to the actual provision of the circuitry of a location-addressed associative memory which has an association part and a data part, handles the tasks of a fully parallel associative memory and has the modularity and cascadeability of a location-addressed memory. In the circuit arrangement, the search word and the mask word of the associative memory form with the aid of a special address decoder the addresses of the memory words which, with their content as a hit identification, indicate whether the items of information searched for have previously been stored and signal the result of a successful association as a hit. The memory carries out simple, parallel write and read operations as well as parallel hit determination in a memory cycle in each case. For the determination of multiple hits, a masked counter is used. Dependent on the search and mask words created, the masked counter generates the addresses of the memory words which can in each case lead to a hit. The actual creation of large bus-oriented main memory areas is possible by the combination of such memory modules, implemented as integrated circuits, with the aid of a special memory selection circuit (chip-select) and a further word residual-bit determination circuit. Such a main memory area can be used at the same time both as a location-addressed memory and as an associative memory. These areas are likewise themselves cascadeable.
