Title: Method for control and display of relative humidity - uses fixed and moving dials with curvilinear scales
IPC: G06G1/14
Filed: 1973-03-22
Abstract: If the controlling device is related to wet-bulb temperature the scale of the fixed inner dial comprises an inner circle graduated in steps of 10 deg.C from 10 deg.C to 100 deg.C representing dry-bulb temp. and an outer circle with the same radially aligned gradiations representing wet-bulb temp. A series of spirals originate on the inner scale and take their values from the points of origin. A spiral scale on the moving outer transparent dial is graduated from 10% to 100% relative humidity in steps of 10%. Alignment of the required relative humidity with the given dry-bulb temp. point by rotation of the outer dial, automatically sets the correct angular input to the controlling device which may function in rotary, linear or other mode. If the controlled variable is wet-bulb dry bulb temp. differential the inner circle of the fired dial is graduated in temp. difference and a pointer moves with the moving dial around it. The fixed dial has a humidity scale and the moving dial a dry-bulb temp. scale. Scale expansion may be used for increased precision.

Title: Mechanical moving-part run-down or stop detector - has position detector reading code on moving part
IPC: G01P13/00
Filed: 1974-05-06
Abstract: The detector consists of a change-over switch (SW) actuated by the position sensor, controlled-loss capacitive stores made-up of a diode, a capacitor and a resistor, and two relays which function as an "OR" logic device. The switch (SW) supplies pulses to the stores at a frequency such as to maintain the stores in an astable state. If the pulse frequency decreases due to a decrease in the speed of the moving part, then the stores may reach a stable state. This stable state will provide a signal to the relays to open the contacts. The level at which the relays operate may be set to correspond to a given speed of or the rest condition of the moving part.

Title: Rail to sleeper fixing clip - has spring steel plates joined by curved section and distribution insert passing through aligned bores
IPC: E01B9/30
Filed: 1974-05-28
Abstract: The flexible attachment for fastening rails to sleepers, comprises an insert (N), an upper plate (L) and a lower plate (M) joined together at one end by a curved section (2).
