Abstract: A method of detecting a position comprising a step for generating two sinusoidal wave signals having phases that are spacially different by 90°, corresponding to movement of a moving body; a step which detects voltages Va, Vb of the two sinusoidal wave signals to calculate a value α which makes the value V = Va.cos α - Vb.sin a zero; a step which so determines the value a that signs of sin α, cos α for said calculated α agree with signs of said voltages Va, Vb respectively; and a step for detecting a position to which the moving body has moved by using the determined value a as data on an absolute position of the body in a cycle of said two phase signals. According to the above method of detecting a position, an absolute position of a moving body can be detected with high resolution.

Abstract: In order to facilitate billing for goods removed from room bars in hotels, receptacles with individual compartments are provided for the goods. Each compartment has a flap or door (3) that is provided with a lock. Together with the room key, the guest obtains an additional key with which he can open the individual compartments of the receptacle. The additional key is constructed, for example, as a hollow cylinder. When the additional key is inserted into a lock of the receptacle, a marking pin (6) is pushed into the hollow cylinder and remains in the key. When the room key and additional key are handed back, the one or more pins remaining in the key indicate whether and, as the case may be, to what extent goods have been removed from the receptacle. Different marking pins can be provided for goods of different value. The marking pins removed by operating the lock can be replaced with other pins after the relevant compartments have been replenished with new goods. <IMAGE>

Abstract: An opto-electronic scanning head for drum and flat bed scanning apparatus for point-by-point and line-by-line scanning of opaque and transparent originals which are illuminated point-by-point. The housing of the scanning head 7 has a front panel 9 which is displaceable along the optical axis 12 of the scanning objective lens 11 and has a housing part which is stationary with respect to the optical axis 12. The scanning objective 11 is mounted in the front panel 9, but the diaphragm 13 and the opto-electronic transducer 14 are mounted in the housing portion 8. The scanning objective 11 can be displaced over a broad range with a sensitive adjustment mechanism for the front panel 9 so that the focus range can always be placed into the image plane of the originals and thus optimum image sharpness can be achieved for originals having all different thicknesses. In the scanning head 7 for opaque scanning, the illumination system 27, 28, 29, and 31 is used for the point to point illumination of the originals and the illumination system is arranged in the displaceable front panel 9 such that the optical axis 30 extends through the focus range of the scanning objective 11 and as a result the illumination system 27, 28 and 29 always generates a focus illumination point on the original regardless of the position of the front panel 9 or of the scanning objective 11 so that optimum illumination of the originals is always achieved for all thicknesses of originals and also the optimum image is maintained sharp.

Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidised condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the inner tube (18) walls. For the downward flow of the granular mass at least one return tube (21) is provided. 
     Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by controlling of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting a distribution plate (24) at a level above the return tube (21) outlet into the lower chamber (17), and further by means of a by-pass (61) and a throttle device (71).

Abstract: Transfer means for transferring a continuous elongate product, such as wire, bar or tubular products associated with a continuous extrusion machine, between two stations in the production line. Axial tensioning means 8, 10 each consisting of a pair of resiliently tyred wheels 12,14 positioned to grip the elongate product 2 and driven by a low interia, electric, motor induce an axial tension in the elongate product 2. The elongate product forms a curve 20 of catenary form between the axial tensioning means 8, 10. A control signal indicative of the gravitational deflection of the curve is derived from an ultra- tight dancer arm 22, or an optical or ultra-sonic sensor, and is utilised in combination with a signal derived from product speed sensor means 24 to control the speed of the low interia, electric, motors and thus the tension in the elongate product By providing the axial tensioning means 8, 10 a degree of transient tolerance is obtained between, for example, extrusion speed and spooling speed thereby avoiding axial and radial deformation of the elongate product during transfer along the product line.

Abstract: A control valve for automatically maintaining a constant rate of flow of a fluid through a pipeline includes a housing having therethrough a passage including an inlet opening and an outlet smaller than the inlet opening. An orifice plate is positioned within the passage adjacent the outlet opening, the orifice plate having therethrough an orifice. A regulating diaphragm is positioned within the passage at a location upstream of the orifice plate. The regulating diaphragm has therethrough circumferential ports and a central opening smaller than the orifice. The regulating diaphragm is formed of an elastic material such that the regulating diaphragm is deflectable toward the orifice plate in response to pressure differences across the control valve between a maximum deflected position, whereat the regulating diaphragm abuts the orifice plates, thereby closing the circumferential ports, and fluid flow is restricted by the central opening, and various positions whereat the regulating diaphragm is spaced from the orifice plate, thereby allowing fluid flow through the circumferential ports.
