Abstract: ABSTRACT OF THE DISCLOSURE        A slack adjuster for axially moved push rods is provided.          An axially extending rotating actuating shaft turns a helical, driving cam member that in turn axially displaces a non-rotating driven cam member.  The driving and driven helical cam members are located in a housing with the actuating shaft extending out of one end thereof and a threaded push rod extending out of the other end of the housing.  A helical return spring is positioned between the driven cam and the inner wall of the housing to bias the cam members together.  The push rod is held against rotation intern-ally of the housing by a flange whose periphery is frictionally engaged by the return spring.  A nut is threaded onto the rod and engaged by the driven cam member to transmit axial force to the push rod; and relative extension of the push rod from the cam members is accomplished by a one way spring brake acting on the nut and a disc clutch drive between the driving cam and nut.  Lost motion is provided to prevent rotation of the nut on the rod during normal push rod clearance, and rotation of the nut on the push rod occurs when excessive push rod clearance occurs.

Abstract: ABSTRACT OF THE DISCLOSURE           Systems that judge the good or bad of moving objects to be inspected by processing image signals from a video camera which picks up the objects at an inspection circuit, are disclosed whereas each time the moving objects to be inspected arrive at the position to be inspected, a position detection signal is generated from a position detection system.  This position detection signal drives the light source to irradiate light for a short time period onto the object to be inspected when it arrives at the inspection position and then such irradiated inspected object is picked up by. the video camera as a static image.  In this case, the image signal and position detection signal are both applied to a signal process and generation circuit so that this circuit generates a control signal with the voltage corres-ponding to the level of the image signal of the first field and also an enable signal at high level during the second field period of the image signal, and then the image signal, control signal as well as enable signal are all fed to the inspection circuit to drive the same during the period in which the enable signal is at high level, whereby the inspection system carries out the inspection to judge the good or bad of the inspected objects based on the image signal of the second field.

Abstract: ABSTRACT OF THE DISCLOSURE A firing circuit for two antiparallel-connected power thyristors. Each of the power thyristors has a gate terminal; the gate terminals being con-nected by a series combination of auxiliary thyristors.  Each of the auxiliary thyristors is of the type which can withstand firing resulting from excessive anode cathode potential; the sum total of the anode cathode potentials of the series-connected auxiliary thyristors being less than the anode-cathode break-down voltages of the power thyristors. Thus, while a power thyristor is in a nonconductive state, an anode-cathode voltage is impressed thereacross in the forward conduction direction.  At an anode-cathode voltage which is less than the breakdown voltage of the power thyristor, the auxiliary thyristors are fired so as to form a conductive path which includes the cathode-gate path of the other power thyristor, the auxiliary thyristors, and the gate-cathode path of the protected thyristor.  Normal firing of the power thyristor is achieved via the auxiliary thyristors, which may be fired by light pulses or current pulses.  Thus, the auxiliary thyristors perform protective and normal firing operations.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for leaching copper from copper sulphide containing ore, in particular copper from chalcopyrite containing ore, is provided.  The ore is preferably in-itially ground up and mixed with an aqueous acid leaching medium containing sulphide oxidizing bacteria, and a bacte-rial nutrient, and a catalytic amount of silver.  Provision is made in the bacterial nutrient for a source of carbon dioxide and oxygen for the bacteria, both of which may be supplied by means of sparging with carbon dioxide enriched air.  A bacterial compatible acid is added initially to the ore and leaching medium mixture and periodically during the process so that sulphide in the copper sulphide is oxidized in stoichiometric amounts to elemental sulphur.  During leaching the oxidation potential is maintained between about .54 to .66 volts, most readily by initial addition of thio-sulphate and dissolved copper.

Abstract: ABSTRACT: "Method of and device for determining the distribution of radiatiof attenuation in a body section".           Using the method and device for computer tomo-graphy in accordance with the invention, always the same filtering operation can be performed for image re-construction, regardless of the method used to measure the measurement data: parallel (whether equidistant or not) or divergent (whether equiangular or not), provided that before and after the filtering of the measurement data there is performed a multiplication by a pre-con-ditioning factor and a post-conditioning factor, respec-tively. The pre-conditioning and post-conditioning fac-tors are dependent on the type of reconstruction and on the position of a measurement data value in the group of measurement data filtered or to be filtered. The fact that the same filter can be used is important notably for computer tomography apparatus in which the (convo-lution) filter is embodied in an electronic circuit (by means of hardware). The back projection device of a de-vice in accordance with the invention is suitable for the back-projection of measurement data along either di-vergent measurement paths or parallel measurement paths for which it requires only the modification of a few constants applied to the back-projection device.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention seeks to provide a method in which the soda lye obtained as a result of cellulose cooking pro-cess and unslaked lime are used for producing white liquor which can be reused in the cooking process.  In this method, the heat released by the slaking of lime with soda lye is recovered by a high pressure slaking process wherein the heat is transferred, either to the steam separating from the lye, which steam is then led to the desired application, or to some other medium to be heated.  The present invention is characterized in that the soda lye to be causticized is divided into two parts, one of which is used for the slaking of lime by adding to it all the unslaked lime needed for the causticizing process, and that, following slaking, the two volumes are brought together for the actual causticizing reaction involving the total amount of lye needed. The present invention provides the advantage that the amount of lye needed is smaller, and so the temperature can be increased.
