Abstract: SUPPRESSION OF CHROMINANCE SIGNAL CONTAMINATION OF THE LUMINANCE SIGNAL   IN A VIDEO SIGNAL PROCESSING SYSTEM                 Abstract of the Disclosure Apparatus in a video signal processing system for improving the quality of a color image reproduced by a color kinescope in response to chrominance and luminance components of the video signal, the chrominance signal being subject to phase transitions likely to generate chrominance subcarrier components sufficient to contaminate the luminance signal.  Chrominance signals delayed by an amount corresponding to an interval during which the phase transitions can occur are supplied to inputs of a signal multiplier, which provides an output signal indicating the presence of chrominance phase transitions.  The multiplier output signal is utilized for controlling the luminance signal processing channel to suppress the sideband signals, thereby also suppressing objectionable effects of the sideband signals otherwise visible in a reproduced image.

Abstract: ABSTRACT OF THE DISCLOSURE A process for converting tree bark into microbial or single cell protein in which finely divided, milled tree is extracted in dilute aqueous alkali solution and then fer-mented, under carefully controlled conditions of temperature and agitation, with a selected white rot fungi.  The fungi breaks down cellulose in the bark to form a microbial which is relatively high in protein and which can be used as an animal feedstuff or further processed to produce an alkali soluble protein concentrate.  A particularly suitable fungi is Phaneruchaete chrysosporium.

Abstract: QUASI-VERTICAL SYNCHRONIZING SIGNAL GENERATOR     ABSTRACT OF THE DISCLOSURE     A quasi-vertical synchronizing signal generator is disclosed, for use with a helical scan video tape recorder (VTR) to generate a quasi-vertical synchronizing signal during a special video effects reproducing operation, which signal occurs at the same relative location during the scanning trace of the reproducing head even if the effective length of that trace varies in accord-ance with the special video effects then in operation.  A signal is produced when the head reaches a pre-established location in the track which it is scanning, and then a delayed signal, which is delayed from the time that the head reached the pre-established location, is generated, this delayed time being selectable as a function of the particular special video effect which has been selected for operation.  The delayed signal constitutes the quasi-vertical synchronizing signal.  In one embodiment, the actual vertical synchronizing signal is recorded in each track that is scanned by the head, and the signal which is produced when the head reaches a pre-established location is the reproduced vertical synchronizing signal.  If the selected special video effect results in a longer-than-normal effective length of the scanning trace, then the quasi-vertical synchronizing signal is produced with a greater delay than if the selected special video effect results in a scanning trace of smaller-than-normal effective length.  In accordance with another embodiment, the signal which is produced when the head reaches its pre-established location is generated by counting the number of horizontal synchronizing signals which are reproduced during the scanning trace, and when a predetermined -i-number has been counted, the location-representing signal is produced.  If the effective length of the scanning trace is greater-than-normal, this predetermined number is higher than if the length of the scanning trace is less-than-normal.     -ii-

Abstract: ABSTRACT     A cylinder lock comprising a fixed, hollow cylinder housing and therein a plurality of tumbler discs turnable by means of the key of the lock. Each tumbler disc has a peripheral recess, and there is a locking bar extending axially relative to the locking discs and being radially guided by them when moving between an outer locking position and an inner releasing position. There is also a turnable force-transmission member non-turnably connected to the locking bar. Between the locking discs, there are spacer discs, each provided with a peripheral recess at the position of the locking bar. This recess is so formed, that it guides, in the tan-gential direction of the spacer discs, the radial movement of the locking bar. The locking discs as well as the spacer discs are turnably guided and radially supported directly by the internal surface of the cylinder housing. The locking discs, the spacer discs and the locking bar have guiding surfaces acting in a tan-gential direction of the lock. These surfaces provide a tangential locking of the spacer discs relative to the locking bar in all functional positions of the lock as well as fixed limits for the movability range of the locking discs relative to the locking bar and means for obtaining a force transmission from the locking discs to the locking bar at the limits of the movability range of the locking discs.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a new structure for a subsurface junction field effect transistor (SJFET) and a new process for its fabrication, the process being especially compatible with existing processes for the fabrication of bipolar devices. Spaced zones of p  type are diffused into an n-type epitaxial layer to terminate the channel and connect to source and drain terminals.  Spaced zones of n+ type are diffused into the epitaxial layer to define the channel width.  The corresponding zones for the bipolar device can be formed at the same time.  A passivating layer of silicon dioxide is applied and the subsurface p type channel formed by ion implantation to leave a thin n-type layer between the channel and the silicon dioxide layer.  Upon application of a metal layer over the silicon dioxide layer in the neighbourhood of the channel, and its connection to the back gate terminal, a stable electron accumulation layer forms at the surface of the n-type layer which interfaces with the silicon dioxide layer.  This electron accumulating layer buffers the device against variations in the characteristics of the silicon dioxide layer and its interfaces with the adjacent layers.  The resultant matching of devices on the same chip or wafer is equivalent to that of more complex and time-consuming prior art processes requiring a second implant step to produce a buffering n+ type layer.

Abstract: Abstract of the Disclosure There are disclosed aqueous dispersions of salts, e.g., tertiary amine salts, of polyamine-extended, aromatic polyisocyanate-based prepolymers having carboxylic groups, especially such dispersions made from prepolymers of polyisocyanates in which the isocyanate groups are on different aromatic rings.  These products, as well as, aqueous dispersions of salts of prepolymers of aromatic polyisocyanates can be made from blocked, aromatic polyisocyanate-based prepolymers, particularly oxime-blocked prepolymers.  The polymer salts can have sufficient neutralized, carboxylic groups to provide stable, aqueous dispersions, and the dispersions of the polyamine-extended polymers have infinite dilutability with water and excellent resistance to gelling upon freezing and thawing.  Carboxylic groups can be supplied to the prepolymers by reactants having two or more groups containing isocyanate-reactive hydrogen atoms employed in making the aromatic isocyanate prepolymers, particularly dihydroxy alkanoic acids.  The polymer salts may be stably dispersed in the aqueous medium, even in the absence of substantial amounts of cosolvents, and the aqueous dispersions of the extended prepolymers are useful as, for instance, coatings for solid substrates to provide water resistance.  The solvent resistance of coatings made from the polyamine-extended dispersions of polyether-derived prepolymers may be increased by using at least trifunctional amines to extend the prepolymers.
