Abstract: Drilling jig for measuring and marking out with high precision a number of borehole positions for later drilling. The drilling jig contains a rectangular or square frame 2, 3 and arrangements 15, 22, 23 for controlling a marking tool or a drill, so-called dice, which arrangements can be adjusted relative to the frame 2, 3, and arrangements 28 for fixing a workpiece 1 in the frame 2, 3. The drill jig is characterised in that the insides 6 of said frame 2, 3 are designed and adapted to perform a high-precision measurement against them, and there are at least two rulers 12 situated between and at two opposite sides 2 of said frame 2, 3, arranged so that they can be fixed and moved along these frame sides 2 and with their longitudinal direction perpendicular to the longitudinal direction of the frame sides 2. Furthermore, the drill jig is characterised in that, at each ruler 12, there is at least one so-called die 15, 22, 23 with one or more surfaces 19, 20, 26, designed and adapted to perform a high-precision measurement against it, which is arranged so that it can move along the ruler 12 between said frame sides 2, and be fixed at the ruler 12. Therefore, with the help of the drill jig, one can measure out at least two borehole positions with high precision and keep them adjusted. The measurement is done, for example, with gauge blocks, which are placed during the measurement between the insides 6 of the frame sides 2, 3 and the surface or surfaces 19, 20, 26 of the dice 15, 22, 23 intended for this. <IMAGE>

Abstract: Method for determining the scorching of a liquid product being treated in a pasteurisation and refrigeration layout, and arrangement for carrying out the method. In a pasteurisation section, one measures the compound resistance for the product heated to the pasteurisation temperature and the scorched product layer at the heat exchange surfaces of the plates, and the resistance of the initial liquid product. After this, one determines the quantity of scorched product as a function of the difference in the measured resistances. The arrangement contains at least two adjoining heat exchange plates with electrically conductive surfaces. One plate is grounded while the other plate is electrically insulated. An arrangement which determines the quantity of scorched liquid product is comprised of a balanced electrical bridge circuit 74 and an element 75 for measuring the imbalance voltage across the bridge circuit 74. One vertex 77 of the bridge circuit 74 is connected to the electrically conducting heat exchange surface of the electrically insulated plate of the pasteurisation section 8, while its other vertex 79 is connected to the electrically conducting heat exchange surface of the electrically insulated plate in a recycling section 9. The grounded vertex 80 of the bridge circuit 74 is connected to an electric current source 76 and to the electrically conducting heat exchange surfaces of the grounded plates in the pasteurisation and recycling sections 8 and 9, respectively. The vertex 78 of the bridge circuit 74 is connected to the current source 76, while its vertex 77 and 79 is connected to the electrically insulated plates and to the element 75 for measuring the imbalance voltage across the bridge circuit, which is proportional to the quantity of scorching.

Abstract: Indicator module with a number of indicators E1-E4 and decoding and holding circuits A1-A4 which is connected between a data bus input DI and the various indicators in order to convert the bit groups occurring at the data bus input into control signals for the indicators. An addressing arrangement, preferably in the form of a shift register SK, is connected to an enable control signal input AI and is configured such that it consecutively starts the activation of the individual indicators of the module only after a particular enable control signal occurs at said enable control signal input. Furthermore, each module has a "last-digit-clear" indicator, for example, in the form of a flip-flop FF, which enters into operation when the last indicator of the module has been activated and thus puts out a signal corresponding to said enable control signal to an enable control signal output AU. By connecting the enable control signal output AU of one module to the enable control signal input AI of a following module, the different modules can be activated in proper order. An entire instrument panel can be constructed from a number of identical indicator modules of simple design, which are controlled via a data bus line L from a common control layout, such as a microcomputer MD, which consecutively furnishes bit groups corresponding to the symbols or digits being indicated. The invention can be used in medical equipment, such as X-ray systems. <IMAGE>

Abstract: A method for ascertaining radiochemical homogeneity in a liquid scintillation sample reliably identifies inaccurate geometries is disclosed so that meaningful activity counts can be determined. The novel method involves measuring the activity level of a set of homogeneous quench standard to obtain quench indicating parameter, or the Spectral Index of the External standard (SIE). The endpoint of each standard sample is computed allowing the formation of a table so that a calibration curve for each radionuclide of interest can be computed. The activity level of the unknown sample is then measured and the SIE determined so that an endpoint can be calculated. Finally, the theoretical endpoint obtained from a calibration curve is compared to the computed endpoint; if the computed endpoint of the sample deviates by more than 4% for tritium and 5% for higher energy radionuclides from the theoretical endpoint, the sample is considered to be nonhomogeneous or heterogeneous. An external standard-type liquid scintillation counting system is disclosed which automatically determines sample homogeneity, and it includes a microprocessor in its control system. The steps of the present invention and incorporated into the programmed steps for the microprocessor such that nonhomogeneous or heterogeneous samples are automatically identified on the readout of the system for an investigator.

Abstract: A side channel blower of the type used as a combustion air blower for motor vehicle heaters wherein a vaned impeller compresses air within a channel formed in a blower. The blower housing has an inlet opening and a discharge opening, between which there is a cross piece. In order to increase the compression pressure which can be achieved with the side channel blower, the inlet opening is in an axial plane and empties into the side channel in the direction of rotation of the impeller. Furthermore, the cross piece has a substantially uniform length in the circumferential direction of the flower and extends into close proximity to a boundary edge of the inlet opening that extends across the flow channel so that an axial projection of the inlet opening onto the plane of rotation of the impeller is as small as possible relative to the area of the inlet opening in the axial plane. To adjust the output of the blower, a bypass opening is provided in the wall of the side channel, at a point from approximately one-third to one-half the circumferential distance toward the inlet open from the discharge opening. In this way, a blow delivery characteristic can be achieved with the bypass opening open that is substantially directly proportional to that achieved with the bypass opening closed.
