Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to toy vehicle track sections a number of which can be joined end to end to complete a vehicle track.  The section includes at least one path for a vehicle with at least two electrically-conducting strips from which the vehicle obtains its electrical power.  The strips extend from end to end of the section and are parallel with one another.  Each end of each electrical strip is housed in an individual tapered recesses and the strip does not extend beyond the recesses.       Each recess tapers width-wise in a direction away from the end of the section and includes an abutment wall adjacent the end of the electrically-conducting strip and a cam wall inclined to the longitudinal direction and arranged to engage a corresponding cam wall on an adjacent section when two sections are brought together so as to wedge the ends of the strips contained within those recesses into side by side engagement between a pair of abutment walls.  At each end of the section, there are snap-fitting retaining means to maintain the sections joined and these means include an open-ended mouth having a restricted opening and a lug capable of entering the mouth and being held therein by the resilience of the mouth and/or lug. The direction in which the lug enters and leaves the mouth is generally parallel to the cam surfaces.  In such a toy track section the recesses house the ends of the electrically-conducting strips and so protect them from damage and sharp edges are also avoided.          Further, the wedging between two adjacent abutment walls when two sections are joined, brings the metal strips into good electrical contact and provides good electrical continuity to a vehicle passing over the join.

Abstract: STARTING CIRCUIT FOR A SPLIT SECTION GAS DISCHARGE LASER         ABSTRACT In an ignition circuit for a split section gas discharge laser having a common anode, a positive sustaining voltage is applied to the common anode while independent negative starting potentials are applied through high resistances to cathodes at either end of the laser tube which are grounded through diodes to prevent shorting of the ignition voltage source while providing a return path for the sustaining voltage source.  The cathodes are immediately brought to ground potential upon ignition so that gas discharge in each of the two sections May be independently ignited while mirrors at either end of the laser tube are maintained at or near ground potential during operation of the laser after ignition.

Abstract: Abstract of the Disclosure A catalytic promoting material is supported on a monolithic support member, of the type generally referred to as a "honeycomb" support, having longitudinal fluid flow channels extending through it.  The catalytically promoting material is dispersed as a coating on the walls of the fluid flow channels which are nominally polygonal, preferably nominally square, in cross section profile so that the walls forming the flow channels can be made as thin as possible consistent with an acceptable thermal and mechanical strength. However, the juncture of the channel walls forming the flow channels are filleted to provide a concave profile, preferably one having an arcuate shape in cross section, so that the corners are "filleted" or "rounded", to subtend an appreciable segment of the nominal width of the channel wall.  This prevents or at least reduces the accumulation of excess catalytic material which occurs in the sharp angular corners of prior art structures.

The piston is formed to provide an inlet port on the outer wall thereof, and an outlet port on the inner wall, the outlet port being positioned in com-munication with a passage to the interior of a hollow shaft at predetermined intervals during rotation of the shaft.  The cup and piston have engaging cam faces formed to cause the piston to move along the shaft against the bias of the spring during a portion of the cycle of rotation of the shaft to open the inlet port and further formed to provide abrupt return move-ment of the piston toward the cup under the influence of the biasing means to close the inlet port and force lubricant through the outlet port into the hollow interior of the shaft.  The lubricant is pumped to the top of the hollow shaft and then distributed to the portions of the transmission requiring lubrication.

Abstract: TITLE:  HYDRAULICALLY SET WELL PACKER        ABSTRACT OF THE INVENTION    A double grip well bore packer which is run into a well casing on a tubular conduit string has actuator means responsive to applied fluid pressure to set slips and to force a packing into engagement with the casing, and the setting force is locked into the  packing.  The applied setting force results from relative axial movement between an inner body mandrel, a setting mandrel and a housing surrounding the lower end of the inner body mandrel to define a pressure chamber housing a releasing piston.  A bottom member defines the lower end of the housing and provides a mounting for a removable plug which closes the tubing bore to permit build-up of tubing pressure to set the packer, including limited pressure induced upward movement of the inner mandrel body relative to the bottom member to facilitate the application of the setting forces.

Title: Method and apparatus for analysing ore by means of gamma radiation

Granted: 1984-06-05
Abstract: Disclosed is a method and an apparatus for analysing pieces of ore for the purpose of sorting. Each piece falling by the analyser is irradiated individually by means of two gamma radiation sources operating at different energy levels so selected that, as to the scattering effect, at one level the Compton effect is predominant and at the other level the Compton effect and the photoelectric effect compete with each other. The former effect is strongly dependent on the ordinal number of the element and, thus, by detecting with at least one detector the scattering intensities produced with the said two sources of radiation and comparing the scattering intensities with each other, the proportion of heavy elements in the ore piece can be determined and the ore piece can be classified on the basis thereof. For example, one energy dispersively operating scintillation detector can be used for detecting the scattered radiation.

Abstract: TRACER TYPE METAL WORKING MACHINE     WITH IMPROVED FEATURES               ABSTRACT OF THE DISCLOSURE         A metal working machine has a tracer and co-ordinate drive control which are connected through the X and Y drive motors and encoders to an input of a CNC unit mounted on the machine.  The CNC is separately connected to a tape recording device and can record the tracer movements on the tape.  Additional machine commands can be added via the CNC.  The CNC memory can be loaded or programmed either via the tracer itself or subsequently from the recorded tape for later machine controlling playback independent of the tracer or tape. The CNC is further connected to a digitizing device which makes it possible to reduce the amount of positional in-formation which must be stored by the memory.  This is accomplished by manually or automatically varying the positional sampling rate according to the contour and dimensions of the workpiece.  When the sampling rate is varied automatically, the information reduction device is provided with a feedback from the tracer.  More specifically, and in either the manual or automatic mode, the positional sampling rate is controlled by a variable repetitive timer.

Abstract: INVENTOR: WERNER HONEGGER          INVENTION:  METHOD AND APPARATUS FOR THE LONG-TERM PRESSING             OF PRINTED PRODUCTS, ESPECIALLY NEWSPAPERS     ABSTRACT OF THE DISCLOSURE     The inherent tendency of printed products, especially newspapers, to change their shape, for instance, because of residual stresses or a restoring action, is to be annihilated by subjecting the printed products to a pressing or compression action. By winding-up the printed products arranged in an imbricated formation and by rewinding the same in the opposite winding sense the products are initially curved in a first dir-ection and then in another direction and pressed into a flat condition. Already during the time that the products are wound into a product package the products become more uniform, as such possibly would be otherwise attainable due to the action of pressure forces over longer periods of time with the utiliza-tion of a great amount of equipment expenditure. The winding and rewinding, but also the unwinding, as these terms are used herein, constitute operations accomplished with the aid of a separation or partition element which is under tension, the end of such separation element being connected with the related winding mandril and being wound into the wound package.
