Abstract: A light grid arrangement features a row of light emitting diodes 0 to 9 which are periodically switched on one after the other by a ring counter 11 and are arranged to direct their light through a monitoring region 23 towards an image forming optical means which is conveniently in the form of a concave mirror 24. The light beams are concentrated by the concave mirror 24 onto a photodetector 18 arranged behind a slot aperture 25 located at the focal point of the concave mirror. Missing pulses from the photodetector are detected by processing circuitry 26 to indicate obstruction of the light grid. 
     The width of the slot aperture 25 restricts the width of each individual light beam so that only beams of light from the light emitting diodes that are generally parallel to the axis of the concave mirror are detected. In this way costly optical focussing elements are avoided as are the difficulties of aligning these optical elements with the other optical components of a system. The length of the monitored region can be increased as desired by placing a number of concave mirror and light emitting diode arrangements alongside one another.

Abstract: The invention contemplates an upright microscope construction and a system of interchangeable specimen holders for selective use therewith, to accommodate a variety of types and sizes of specimens, such that, whatever the inserted specimen-bearing holder, the specimen surface to be observed, whether by transmitted light or by reflected light, will be in focus, i.e., in the focal plane or effectively in the focal plane of the microscope. This result is achieved by building into the microscope stage a reference-abutment surface having a predetermined relation to the focal plane of the microscope, and by devising all holders of the interchangeable system to support their intended kinds of specimens in such relation to the part of the holder which abuts the reference-abutment surface, that the inserted holder places the desired specimen surface in the focal plane of the microscope.

Abstract: The loop current (Ix) of a telephone set speech network (11) is automatically initialized at a desired level independent of the central office voltage applied to the inputterminals (12, 13) of the set and thus independent of transmission line loop length and other variables. For this purpose, a variable conductance device (20), such as a Darlington driver (Q1), is connected between the input terminals and the speech network so as to establish a loop current at a circuit node (N1) that is a function of the supply voltage and the conductivity of the device. The loop current is monitored, as by a Schmidt trigger circuit (30), and the conductance of the device (20) is varied accordingly so as to initialize the loop current at the desired level, as by selectively connecting a plurality of resistors (R2 ...R7) individually and collectively between a base node (26) of the driver (Q1) and the ring lead (17) of the set.

Abstract: A multi-stage pressure regulating system including a pilot-governed main pressure reducing regulator (12), with one or more passive back pressure regulators (14) arranged in tandem therewith. The regulators are valves of the type conditioned to open when the upstream pressure therein overcomes a jacket (30) pressure. The jacket (30) in the main valve (12) is loaded by upstream fluid, but a pilot (36), which monitors a particular fluid flow characteristic, such as pressure, at a selected location in the pipeline, controls bleeding of the jacket as necessary to regulate flow through the main valve so as to maintain a predetermined value or level of the characteristic being monitored. Hence, flow through the main valve is controlled solely by the pilot device, but its discharge to the ultimate downstream level is through at least one auxiliary valve, the jacket (30a) of which is loaded with a pneumatic pressure (P ja ) at a suitable level, so that the pressure drop to the downstream level is in two or more stages.

Title: Valve unit for water closets
Inventor: BASLER BRUNO
IPC: E03D9/14
Filed: 1981-10-01
Abstract: The invention provides a float controlled valve, the valve having a valve member which engages a seat to close the valve. The valve member has an area which is subjected to the supply pressure in such a position tending to close the valve so that the higher the supply pressure, the greater the force tending to close the valve, said area being larger than the area of bore through which the waterflows when the valve is open. Also, water flowing through the valve into the cistern tank passes into a down tube having a diaphragm preventing flow of water through the tube other than through drain apertures in the diaphragm, and outlet apertures between the valve and the diaphragm to prevent siphoning back of water from the cistern tank. The drain apertures prevent trapping of water in the down tube in the event of the cistern being emptied.

Abstract: An incremental length measuring instrument generates analog scanning signals S1, S2 with a certain period P which are applied to a comparator in conjunction with two reference signals RS1, RS2. The measuring instrument causes the scanning signals S1, S2 to change as a function of relative displacement to two components of the measuring instrument. The comparator generates an analog control signal SD as a function of the difference of the momentary values of the signals applied as inputs to the comparator. The analog control signal SD is applied as an input to a signal generator which includes an oscillator. The oscillator generates a number of pulses in dependence on the momentary value of the analog control signal SD. These pulses cause the reference signals RS1, RS2 to be modified by the signal generator. In addition, the pulses are fed in a direction dependent manner into an incremental counter which includes a numerical display. The counter maintains a count which is displayed as an indication of the relative position of the two components of the measuring instrument. The reference signals RS1, RS2 are modified by the pulses generated by the oscillator until their momentary values correspond to the momentary values of the scanning signals S1, S2. When this occurs, the difference between these momentary values is zero and the comparator no longer delivers the control signal SD, thereby causing the pulse generation by the oscillator to cease. When this happens, the displayed counter state on the incremental counter and the reference signals RS1, RS2 remain in their momentary states.
