Abstract: FLUID DEFLECTING ASSEMBLY            ABSTRACT OF THE DISCLOSURE     The specification discloses a fluid deflecting assembly for deflecting a fluid medium in any desired direction, particularly suited for use at the outlet of an air conditioner.  The assembly comprises a nozzle for issuing a main stream of fluid as the fluid passes there-through, a guide wall at a position downstream of the nozzle and having a curved shape in a direction downstream with respect to the direction of flow of the main stream and opening outwardly in a direction away from the nozzle, and a mechanism for controlling the mode of flow of the fluid at a position upstream of the nozzle.  The nozzle has a relatively small thickness in the direction of flow of the fluid therethrough and is so shaped as to constrict the flow of the fluid as the latter passes therethrough.      In this way, a relatively large angle of deflection of the fluid stream can be attained even though the device can be quite simple and compact.

Abstract: DRIVE ARRANGEMENT FOR SETTING      MECHANICAL APPARATUS, ESPECIALLY THERMOSTATS          Abstract of the Disclosure The specification discloses a drive arrangement for a thermostat or the like.  The drive arrangement includes a shaft located in a bearing in a housing in such a way that one end of the shaft extends out of the housing and is fitted with a knob or the like for twisting the shaft in the bearing.          The other end of the shaft has a collar extending through a disc-like cam.  The cam receives the collar through a bore having a slot extending radially therefrom.  The protruding end of the collar is expanded by a punch or the like and, since the material of the cam is harder than that of the shaft, the slot in the cam acts as a die and cuts out a tab from the shaft material, which extends into the slot and securely fixes the cam to the shaft.  In this way the shaft and cam can be simply and securely fixed together in a very economical manner so that torsional slipping therebetween can be avoided.

Abstract: ABSTRACT      A method of operating a heat pump including a multispeed compres-sor and a heat pump apparatus including a multispeed compressor, wherein the compressor is actuated at a relatively high speed during the normal heating mode of operation and at a relatively low speed during the heating mode of operation when frost accumulates on the outdoor coil so as to de-frost the outdoor coil without actuating the reversing means of the heat pump system. The lower end of the operating range of the heat pump can be extended by running a heat pump system including a two-speed compressor at low speed during ambient conditions of about 0°F. At low speed operation, the effective outdoor coil surface is twice that at full speed and the heat pulp system can continue to operate without resorting to more costly auxiliary electric strip heat.

Abstract: ABSTRACT OF THE DISCLOSURE      A digital video display system wherein the various characters to be displayed are displayed in the form of images of the complete character rather than the standard dot-matrix pattern of the prior art.  A character genera-tor in the display system stores signals representing the various characters to be displayed which are retrieved from storage in response to a character code.  The signals are in the form of a binary code having a sufficient number of bits to represent a different number of levels of gray-scale or luminance values for the various picture elements making up the character image.  The binary codes thus retrieved from storage are supplied to a video synthesizer that generates the video signal to display the character images which may be displayed in a number of different modes including white-on-black, black-on-white, black-on-gray, and white-on-gray as well as different combinations of such modes to represent a cursor.  The video synthesizer can generate output voltage levels in discrete stops for the different luminances to be employed.  The voltage out-put signals differ from level to level in accordance with the 2.2 root of luminance.

Abstract: 30.8.1978                1                    PHN 8909 ABSTRACT Examining device for determining local absorption values in a slice of a body.                           In transversal tomography devices in which the X ray beam and the array of detec-tors are such that they cover the higher slice to be examined, a very large array dynamic range (the ratio between the largest detector signal and the smallest detector signal occurring during a measurement) occurs. The array dynamic range often lies between the values 104 and 2.104.  By adaptation of integration capacitances of the integrators connected to the detectors to the posi-tion of the detector in the arrays the array dynamic range can be reduced. If the ratio between the largest integration capacitance (at the end of the row) and the smallest integration capacitance (in the centre of the array) equals, for example, 40, the array dynamic range is substantially smaller than 1000. The advantage consists in that less severe requirements are imposed on the signal processing section connected to the integrators.
