Rode Attorneys:     HOSIER, NIRO, & DALEIDEN                135 S. LaSalle St., Room 640 Chicago, Il 60603 ABSTRACT OF THE DISCLOSURE                Methods and apparatus are disclosed for inhibiting the unauthorized copying of ROM-resident computer software or the like, for example, the audio-visual display of an electronic video game. A protection circuit including encryption/decryption means is coupled between the microprocessor and the ROM-memory and is operable in a first mode to properly encrypt/decrypt the program information according to a first algorithm and in a second mode to prevent proper encryption/decryption. The address-data buses are monitored by the protection circuit to detect an invalid program event, such as may occur when a microprocessor emulator is used to attempt an unauthorized copying or "dumping" of the program information. Upon detection of the invalid program event or "trap condition", the protection circuit switches to its second operating mode thereby to prevent copying of the decrypted program information.

Abstract: Abstract of the Disclosure The invention is directed to a saw chain for a power-driven chain saw. The saw chain includes a plurality of cutting links, a plurality of connecting links and a plurality of driving links. The links are interconnected by rivets to define the saw chain. The cutting links include a cutting tooth and a rearward foot defining a tilt edge. The cutting link tilts about the tilt edge when the cutting tooth penetrates the wood to be cut. In tilting about the tilt edge, the cutting edge of the cutting tooth is raised from a first elevation to a second elevation and the difference between these elevations is the tilt displacement. The tilt edge lies in a vertical plane which is perpendicular to a traverse plane containing the axes defined by the forward and rearward openings for the linkage rivets connecting the cutting link to the rest of the saw chain. The tilt edge is formed on the rearward foot at a location thereon such that the vertical plane lies within the forward half of the cutting tooth there-by reducing the tilt displacement to a predetermined magnitude.          Accordingly, during the cutting operation of the saw chain, the tilt displacement is small and the cutting tooth does not draw itself into the wood to too great an extent where-by a more uniform cutting action by the cutting teeth of the cutting links is achieved and vibration of the saw chain is reduced.

Abstract: FLOW RATE CONTROL AND METERING MEANS FOR         SHEAR-SENSITIVE LIQUIDS     ABSTRACT OF THE DISCLOSURE           In a flow rate control apparatus, pressure of a primary, or controlled, liquid is reduced without application of shear forces thereto.  Each of first and second piston and cylinder assemblies has a first port on one side of the piston and a second port on the other side.  A secondary fluid path between the two second ports contains a controlling fluid directed through a pressure reducing valve.  The rate of flow of tile primary fluid from the discharge cylinder is controlled by the rate of flow of the secondary fluid through the pressure reducing valve.  A four way valve couples the controlled liquid at relatively high pressure through the first port in a first cylinder, and the controlled liquid is dis-charged at relatively low pressure from the first port in the second cylinder.  The first and second pistons are rigidly connected to assure synchronized motion and accurate metering of the controlled liquid and to provide for driving of both pistons in response to input pressure of the controlled liquid.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to laboratory testing pro-cedures and, more particularly, to apparatus for preparing liquid samples of urine and the like for examination. The present invention provides an apparatus and method for preparing liquid specimens, wherein a sample for analysis and observation may be isolated from a larger volume of liquid conveniently and reproducibly.  Varia-tion in the sampling and observation due to differences in the laboratory technique is minimized, and the pre-paration of large numbers of samples may proceed rapidly. Further, the chances of inadvertent mixing of the liquid sample and the liquid to be decanted is minimized.  With this invention, accurate, reproducible analysis of the components of urine and other samples is possible in a large scale, production line fashion.  The apparatus for preparing liquid specimens includes a tube for holding the liquid to be sampled and a pipette or other means for isolating and withdrawing a sample from a portion of the liquid.  In accordance with the invention, the pipette or other means includes retention means for main-taining the seal between the pipette and the tube, there-by resisting the tendency of the pipette to float in the liquid and also holding the pipette in place when the container is inverted to decant the liquid to be dis-carded.

Abstract: ABSTRACT:          "Apparatus for recording and reproducing information on a record carrier in the form of a tape".     In a helical scan video recorder in which the magnetic heads are arranged on bimorph piezoelectric actuators it may be desirable, in order to counteract depolarization of the piezo-electric elements, to bias these elements. This is possible without the use of additional slip rings if the electrode to which the drive voltage is applied is connected, via a diode, to the electrode to which the bias is applied and the bias is applied, alternately with the drive voltage, at instants at which the associated magnetic head is not used. If the (lower) drive voltage is applied the diode is cut off and the bias is isolated from the drive.

Abstract: ABSTRACT A sterile shaped prosthetic device, suitable for insertion into a mammalian body, is at least partly composed of a bioresorbable material that is digestible by macrophages, its surface properties favor the attachment and adhesion of fibroblast cells capable of producing collagen for organized connective tissues, and the material itself or its degradation products can induce in vivo the formation of new capillary vessels (termed a "vasotropic" effect herein).  Preferred prosthetic devices have through passages, the interspatial dimensions which are sufficient to permit several layers of mammalian cells to form within each passage.  The invading fibroblast cells commence formation of collagen leading to connective tissue while macrophages and extracellular enzymes degrade the material, and newly formed capillary vessels penetrate the prosthesis and provide blood containing oxygen and nutrients which further the formation of organized tissue around as well as within the prosthetic device.
