Title: Machine tool fault recognition system - uses comparison of actual and desired value signals using acquisition unit and quantifier
Inventor: PFUELLER SIEGFRIED DIPL ING
IPC: G05B19/4063
Filed: 1979-02-22
Abstract: The machine tool fault recognition system has a fault-signal acquisition unit with a quantifier. Applied to the unit's inputs are actual-stage signals and trend-value signals. These are transmitted at the outputs as evaluated fault signals directly or via a fault-signal summing unit to a fault-signal logic circuit. The circuit outputs are connected to hierarchy levels of the fault and primary-fault display. The logic circuit control signals belonging to the hierarchy levels are connected to the machine-tool control.

Title: Three ball rotating pendulum display for clock - has elastic fixing for suspension of pendulum powered by impulses from second shaft
Inventor: FEHRENBACHER WOLFGANG
IPC: G04C3/033
Filed: 1979-04-19
Abstract: The three ball rotating pendulum (1) is hung by a torsion wire or tape (11) from a fixing (14, 15, 17) which is elastic in that it contains a spring permitting natural adjustment in the vertical direction. The pendulum is restrained from over-rotating by a projection (35) attached to the pendulum which can strike a fixed pin (8b). The pendulum has a fixed natural frequency of about eleven seconds but is forced to oscillate with a frequency of ten seconds by means of an intermittent force applied by the six spokes (25a) of a wheel (25) driven by the second shaft (27) of the clock. This wheel is driven via a spring (30) which ensures a smooth application of just sufficient drive to turn the pendulum at this frequency.

Title: Hydromechanical metering system - prevents dry running of chemicals pump by short-circuit through by=pass valve
Inventor: KERN JOHANN
IPC: G01F11/02
Filed: 1979-08-03
Abstract: Hydromechanical metering device for the injection of a chemical, for example in a fresh water pipe, consists of a metering pump Which is driven by a hydraulic motor in the water main. The chemical storage vessel includes a float which opens a normally closed by-pass valve when the chemical level drops to a min. This connects a pressure valve in the metering pump to the chemical storage vessel and ensures a recirculation of the chemical between pump and vessel. The pump is prevented from running dry and seizing but requires no extraneous energy.

Title: Radio telegraphy monitor with visual display - stores signal and repeatedly replays it at adjustable speed to analyse transmission
Inventor: HISSEN HELMUT DR
IPC: H04L13/08
Filed: 1979-10-04
Abstract: A radio telegraphy signal is monitored by measuring the times between each transition and entering them in a digital store. The signal is displayed on a TV screen with alternate times appearing as bright lines, by repeatedly reading out the stored data. The real time represented by each line of the display is continuously variable. The display can thus be adjusted to align the bright lines vertically, similar to a Hell-diagram. Hence the speed and type of transmission can be determined. The display is rolled up as transmission proceeds so that the latest signal is always being written on the bottom line. The phase of the start point can be varied, to shift the pattern sideways without changing line length or speed. The advantage of the method is that no information is lost while adjustments are being made.
Patent DE-2941731-A1 (DE)

The battery is automatically switched to charge when free-wheeling. The pre-selected gear system and battery voltage is monitored via the current between the motor and the battery and if necessary corrected. The control system consists of printed circuit boards using integrated circuits. The gear changes are performed by controllable electromagnetic coils.
Patent DE-3024571-A1 (DE)
Title: Washing machine drum - has controlled water feeds and drum speeds to ensure saturation with reduced water consumption
Inventor: ARENDT HANS F
IPC: D06F23/02
Filed: 1980-06-28
Abstract: On loading the washing machine the horizontal drum rotates at a speed to give a centrifugal force at the drum mantle of 0.2-0.6 g, and the water is fed in until the laundry has absorbed the maximum amount of 45-100 per cent of the volume. During the washing cycle the drum is rotated and then at the end the drum is accelerated for a sufficient period to extract a given volume of washing fluid. This spin drying is repeated to extract a further fluid volume. For the rinsing phase, clear water is fed in by the same amount as for washing, and the drum rotates at the same speed as in the washing cyccle. The drum speed is accelerated for spin drying between rinsing cycles. The process ensures that the washing fluid penetrates into the fabric structure, while reducing water consumption.

Patent DE-3028995-A1 (DE)
Title: Control circuit for electric blanket or heater - has two electronic switches, clock pulse generator controlling second switch, and resistive voltage divider in specified connection
Inventor: ZUERKER HERMANN ING GRAD
IPC: G05D23/24
Filed: 1980-07-31
Abstract: The circuit has a temp. control for the heat conductors, an electronic switch in series with the conductor at operational voltage, and a clock pulse generator for periodical making and breaking of the switch. The actual value generator for the temp. control is the heat conductor proper, the control incorporating a memory, as in 2757334. Parallel to the switch (S1) is a series connection of a bridge resistor (R4') and a second electronic switch (S2) controllable by the clock pulse generator (TG). A voltage divider (R1,P1,R2) is in parallel to the series connection of the heat conductor (RH) and the bridge resistor (RH') for generating a rated value voltage. The clock pulse generator closes the second switch only during the breaking of the first switch, and then only for a brief measuring interval. The bridge resistor and voltage divider may be coupled to both ends of a potentiometer (P2) to whose tap is coupled the second switch.
Patent DE-3029575-A1 (DE)
Title: Stowage structure for electronic equipment in aircraft - has supporting members formed as structural elements with channels for cooling components
Inventor: BOBROWSKI BERND
IPC: B64D47/00
Filed: 1980-08-05
Abstract: The aircraft fuselage (1) is constructed in the usual way from spars and stringers, but has additional vertical and horizontal walls (6,15), formed with cut-outs which act as cooling channels for the electronic equipment. The vertical and horizontal walls (6,15) are for mounting and storing the electronic units, which are constructed as housings (10) containing electronic components. As the partitions formed by the walls are also structural elements, the remaining aircraft structure can be made correspondingly weaker. Therefore the storage spaces do not need to represent any increase in overall weight of the aircraft. To simplify the exchange of electronic components in aircraft of a similar type, a detachable structural element is provided which together with the relevant plug connection and cables can be easily separated from the supporting structure.
Patent DE-3030713-A1 (DE)
Title: Adjustable reclining bed with multi-sectioned frame - has positive cogged, brake block for effective locking without expensive solid structural parts
IPC: A47C20/16
Filed: 1980-08-14
Abstract: The axis of rotation of the vertically movable bed section is mounted on a guide rod set to move like a pendulum about a second axis. One wide face of the guide rod has at the side next to the path of movement about the axis, a toothed strip which is bent concentric with the point of rotation of the guide rod. The pendulum motion of the guide rod can be locked by brake blocks on the side facing the guide rod with counter teeth which engage in the toothed spaces of the toothed strip. This positive keyed locking system ensures a good brake block without expensive structural parts.

Pins or plates acting as the conductor elements lead from this absorbing surface to inside the pan and thus to the contents which are to be heated. The pan itself is insulated to prevent heat loss. It is also possible to design the pan with the conductor elements in the form of grids which can contact the base of the pan allowing flat bread and similar foods to be cooked.
