Patent DE-2940335-A1 (DE)
Title: Methanation of synthesis gas - with recycle of carbon di:oxide as reaction moderator
Inventor: LOHMUELLER REINER DR ING
IPC: C07C1/02
Filed: 1979-10-04
Abstract: In the catalytic methanation of synthesis gas (essentially H2 + carbon oxides), the exotherm is moderated by adding recycled CO2 to the reactor feed. The CO2 is removed from the prod. in a physical or chemical scrubber, which may also remove S cpds. The required CO2 may be generated in the methanator by adding H2O to a CO-rich synthesis gas feed. The reactor may be isothermal or adiabatic. The concn. of CO2 required for reaction damping is less than the concn. of other diluents (H2O or prod. gases) in existing processes, leading to a smaller and cheaper reactor. In comparison with H2O as diluent, CO2 gives a reduced risk of soot formation and an increased yield of h.p. steam by heat exchange from the exit gases. S scrubbing after the reactor (requiring a S-resistant catalyst) is advantageous for synthesis gas contg. CO2. In the methanator, this yields CO2 and H2S, the H2S requiring a smaller scrubber for its removal than CO2 does.

Title: Model electric car system - uses four collector shoes and diode pairs and runs on track with multiple rails alternately positive and negative
Inventor: BROCKHAUS JOHANNES
IPC: A63H18/16
Filed: 1979-10-10
Abstract: The track for electric model cars has longitudinal conductor rails, 10mm wide and spaced apart 10mm, across the whole width of the track and flush with its surface. Odd numbered rails are connected to one DC supply terminal, even numbered rails to the other. A car has four collector shoes, 8mm wide and spaced laterally so that at least one contacts an odd rail, and at least one an even rail. Each shoe is connected via a diode to one terminal, and via an opposite diode to the other terminal of the car's motor control circuit. Thus the car receives the same supply polarity whatever its position on the track, provided it does not depart too far from the right direction.

Title: Metering system for water from rain basin - uses motor to set throttle controlling flow in outflow pipe
Inventor: FAHRNER HEINZ
IPC: E03F5/10
Filed: 1979-11-06
Abstract: The system has an outflow pipe. The rated outflow is not normally controlled. The throttle passes over into a given first position and is held in this position in which the outflow tube is open. When the rated outflow requires controlling as there is a risk of exceeding the rated outflow, the through-flow measuring region of the outflow pipe is filled completely and the control of the rated outflow is then ended when a given first water state is reached in the outflow pipe or rain basin or inlet channel to the rain basin.
Patent DE-2949451-A1 (DE)
Title: Frictional clamp for rod movable axially in tube - using compression and twisting to expand spring inside tube
Inventor: BOTTERILL JOHN R DR
IPC: B60N2/23
Filed: 1979-12-08
Abstract: A frictional clamp consists of a rod (2) able to move axially within a tubular casing (1) contg. a press. spring (10) around the rod and with one end resting on a stop (5) attached to the casing or rod. An operating lever (9) causes the spring to expand and come into contact with the other axial element not carrying the stop. It is applicable in adjustable vehicle seat mechanisms and ensures reliable clamping under high axial loadings, e.g during rapid decelerations. The spring stop is attached to the rod. The spring expansion pushes it against the inner wall of the casing. The spring may be compressed, twisted, or twisted and compressed by the actuating lever which acts on a ring (7) enclosing the rod at the opposite end of the spring from the stop.

Title: Narrow band surface acoustic wave filter - has series-coupled resonators with different modal behaviour, with impedance terminators
Inventor: WALLER WOLFGANG DIPL PHYS
IPC: H03H11/04
Filed: 1979-12-18
Abstract: The surface acoustic wave (SAW) filter has two SAW resonators connected in series one behind the other. The first operates in single-mode with a relatively low Q and the second operates in a multiple-mode with very high Q. The mode of the first resonator accords with one mode of the second resonator. Several such resonators with different modal properties may be connected in series. Isolating capacitors and isolating amplifiers may be connected between the resonators. The resonators may be terminated with small impedances, and all main components are mounted on a piezoelectric substrate such as quartz, ceramic, or lithium niobate.

IPC: G05D23/19
Filed: 1980-03-29
Abstract: Heat sources of an installation are controlled to feed radiators or a hot water storage tank has at least two heat sources of different capacities. At least one timer measures the duration of the last OFF-period and of the last ON-period of the first heat source. A rising trend of both times leads to a rising delay for the ON-signal for the second heat source, and vice versa. Two heat sources (501,502) have burners (505,506) for gas or oil which are controlled by solenoid valves (510,511). They feed either space heating radiators (521) or a hot water preparation tank (518) via a three-way valve (514) which is actuated by a water flow switch (515). A pump (520) circulates the water. The control unit (526) includes a timer and an UP-DOWN counter for the ON and OFF periods of the heat source (501).

Title: Vehicle bumper bar with shock absorbers - has energy absorbing element between bumper bar and shock absorber piston rod
Inventor: URSPRUNG JOSEF DIPL ING
IPC: B60R19/26
Filed: 1980-11-14
Abstract: The bumper is fitted at each end with a shock absorbing system. An energy absorber (23) in the form of a rubber element is fitted between the piston rod (39) of a shock absorber (21) and a cover plate (41) behind the bumper (25).

On more contact with the obstacle by the bumper, the shock is absorbed by the energy absorber elements.
Patent DE-3045217-A1 (DE)
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G08B13/187
Filed: 1980-12-01
Abstract: An active optical monitoring device comprises a transmitter (S) and a receiver (E). The transmitter (S) regularly transmits modulated light pulses in a spatial sector and simultaneously transmits synchronous pulses to the receiver (E). The receiver (E) receives the light detected by its optical system and converts it into electric signals. These signals are filtered in a bandpass filter, amplified in a pre-amplifier (7) and rectified in a rectifier (8). In the pause between two light pulses, the basic optical level is defined in a sample-and-hold circuit (10) which is controlled by one synchronous pulse ( phi 2). The output signal of the rectifier (8) is amplified in an amplifier (9) during the light pulse duration. In a differential amplifier (11), the basic level is subtracted from the signal present during the light pulse duration. Via an analog switch (12) which is actuated by the synchronous pulse ( phi 1) for the duration of the light pulses, the signal is sent to a root extractor (13), post-amplified in an amplifier (14) and forwarded via a further analog switch (15) which is also controlled by the synchronous pulse ( phi 1) to an evaluation and alarm circuit. <IMAGE>

Title: Panel cutting machine - has offset saw-blade shaft, inclined blade holder faces and tapered hard tip
Inventor: WEBER REINHARD
IPC: B27B5/36
Filed: 1980-12-04
Abstract: The saw shaft mounted in a relatively movable assembly has one or more saw blades seated on it. The machine is used for cutting up, or cutting to shape, non-metallic panel material. The shaft (5) is offset by a small angle (alpha) from the direction of thrust, so that the plane of rotation of the blade (1) converges with the longitudinal centre of the panel material. The faces (17) of the blade holder (11) lying against the blade are slightly inclined (alpha) in relation to the shaft radial plane. The hard metal or diamond tip (18) or the blade periphery tapers towards the blade centre. This provides a clean precise cut in multiple as well as in individual cutting for wood and plastic panels.
