Title: Signal selection appts. for redundant signal sources - supplies each channel with weighted average of signals from two less accurate sensors when precision sensor fails
Inventor: MARTIN DONALD LIONEL
IPC: G05B9/03
Filed: 1978-05-09
Abstract: The signal selection and signal consolidation appts. is for use with the redundant sensor signals in a triply redundant control system. One of the redundant sensors supplies precise information and the remaining two sensors supply less precise information. Signal selection is based on the operational state of the three sensors, with the signal provided by the precision sensor being selected whenever the precision sensor is operational. If the precision sensor fails, each channel is supplied with a signal that is a weighted average of the signals supplied by the two less accurate sensors.

Title: Low-impact picking mechanism - having electromagnetically-assisted shuttle acceleration
Inventor: KEPPELER DIETER
IPC: D03D49/44
Filed: 1978-09-26
Abstract: A device for propelling a shuttle across a loom, having an electromagnetic in front of the box, in the vicinity of the shuttle exit, whose field lines on the side of the magnet facing the box run in the direction of movement of the shuttle. The shuttle has a covering of magnetic material on which the electromagnet acts to assists the propulsion of the shuttle through the shed, the magnet being switched off immediately the carrier has passed through the magnetic field by a photoelectric switch which is operated by the passage of the shuttle. Because of the propulsive aid of the electomagnetic, the mechanical impact of the picker on the shuttle can be reduced, which considerably reduces the noise level and increases the life of the shuttle, with a corresponding redn. in loom downtimes and maintenance costs.

Title: On-route rail vehicle control device - initiates braking upon failure to acknowledge data work representing operative signal
Inventor: SCHWARZBACH WALTER
IPC: B61L3/12
Filed: 1979-06-05
Abstract: The control device uses two-way communication between the vehicle (F) and the track-side device.

Title: Packing fluids, slurries, solids, in thermoplastic film hoses - using two ultrasonic welders forming vertical and horizontal seams
Inventor: STEWART JAIN
IPC: B29C53/00
Filed: 1979-06-06
Abstract: The overlapping edges of a film of thermoplastic material formed into a tube are welded by the tool of an ultrasonic welder, which works directly with the filling tube of a packing machine. The machine packs materials ranging from fluids to powders and granulates, into a tube formed by turning a strip of film over a guide plate on to the outer surface of the tube, on which it is welded, filled and sealed by transverse seams spaced out at intervals. The transverse seams are produced by the tools of a second welding device which include the ultrasonic tool and a holding-up punch. These are both movable transversely to the line of motion of the tubular film and they have contact surfaces in the form of an "S" or a "Z". Used to provide a tubular bag machine for the packing of shampoos, fats, cheeses, sausage meat, slurries of explosives, and granular matter. The machine works at much higher speeds than those using glue, and welds thick films without a dangerous level of heat being generated. In addn. the vibration set up by the waves displaces particles which otherwise would remain in the seam.

Title: Telephone conference circuit for delta-modulated speech signals - sums speech inputs digitally representative of signal change and amplitude
Inventor: SCHADE GERD ING GRAD
IPC: H04M3/56
Filed: 1979-08-31
Abstract: The conference circuit comprises a unit with subcircuits for each individual subscriber line, and a conference adding unit. Individual speech inputs are sampled at a system clock rate for converting in a delta modulator rising and falling amplitude levels into +1 or 0 digit outputs which, via an equivalence recognition unit are entered into shift registers and, with the help of a programmable memory register which remembers the result of preceding amplitude changes placed into the register of the actual incremental value circuit produces a digital signal representative of the speech input amplitude. In the adjacent circuit sector all these subscriber signals are collected and added in the conference incremental value step adding circuit from which emerges one single signal in dititized delta modulation form. The same may now be passed through a demodulator for reconversion into analogue form, passed through a low pass filter and distributed to the conference participants.

Title: Kiln for baking ceramic ware, esp, tiles - where auxiliary burners prevent excessive temp drop in cooling zone of kiln when no tiles are passing through kiln
Inventor: SPITZBART HERBERT
IPC: F27D21/00
Filed: 1979-11-28
Abstract: The kiln possesses a heating zone and a cooling zone; and the workpieces travel through the kiln on a roller track using rolls which rotate on stationary shafts. The cooling zone contains at least one auxiliary burner, which can be switched on if and when required. Burners are pref. actuated by a controller receiving signals from a temp. sensor and/or from a sensor indicating that no workpieces are being loaded onto the roller track. When no workpieces are fed onto track, due to a breakdown in prodn., the temp. of zone drops to below its usual value. After the breakdown is eliminated, the first workpieces fed onto track cool too quickly in zone, so they must be scrapped. The invention uses burners to prevent excessive cooling of zone when no workpieces are being fed through the kiln.
