Abstract: F. 0285-169 IMPROVED VIDEO ENCRYPTION SYSTEM Abstract of the Disclosure An encrypted video distribution system includes a signal originating station which distributes television signals in a format unrecoverable by a standard television receiver. In particular, the normally occurring vertical and horizonal synchronizing pulses are deleted and, optionally also, video information is selectively inverted about a voltage reference potential intermediate the black and white levels. To permit synchronization restoration, a keying pulse is transmitted once each video field, and a synchronizing digital code burst transmitted once each frame - all at a fixed, predetermined intra-frame timed relationship. At each authorized subscriber location, the keying pulse and digital code burst are employed to lock a receiver frame clock which derivatively gives rise to all requisite recep-tion-permitting synchronizing pulses. The transmitted information also contains information sufficient to restore the inverted video program content.

Abstract: ABSTRACT OF THE DISCLOSURE    A method for producing antenna follow-up signals in which a sum signal and a difference signal are derived from a received beacon signal and an amplitude modulated signal is produced by superposition from these two signals.  The amplitude modulated signal is converted into another frequency by means of a mixer which receives both the amplitude modulated signal and a mixing signal.  The converted amplitude modulated signal is fed to an amplitude detector via a narrowband bandpass filter which permits only the signal frequency to pass.  A voltage controlled oscillator is cyclically switched to produce a mixing signal which is fed to the mixer and which cyclically changes its frequency between two frequncies for the duration of each phase state of the difference signal.  The converted signal at the output of the mixer changes its frequency between two further frequencies in response to the change of frequency of the mixing signal.  The frequency of the voltage controlled occillator is controlled with a control voltage that is derived from a difference between attenuations suffered by the converted amplitude modulated signal in the bandpass filter at the two further frequencies of such converted signal.

Title: Self-engaging separable fastener
Inventor: PROVOST GEORGE A
IPC: A44B18/00
Filed: 1986-08-13
Granted: 1990-04-17
Abstract: ABSTRACT A self-engaging separable fastener is disclosed which comprises a base member of woven separable fastener material having at least two adjacent mating fastener sections. At least one section is defined by a plurality of loops upstanding from the base member, and the other section is defined by a plurality of hooks upstanding from the base member. The loops are formed of respective generally parallel rows of multifilament yarns interwoven into their respective base section so as to repeat the same loop direction and construction every predetermined number of picks and the hooks are cut from respective generally parallel rows of loops of monofilament yarns interwoven into their respective base section so as to repeat their loop direction and construction every predetermined number of picks, which latter number of picks is greater than the number of picks in which the direction of the multifilament loops is repeated. The density of the monofilament hooks is less than the density of the multifilament loops such that the sections of fastener material may be placed in face-tofane engagement by folding one section over the other and pressing the surfaces together and separated by peeling forces normal to the interfacial plane of engagement. Preferably the loops repeat themselves every four picks and the hooks repeat themselves every eight picks.

Title: Method for increasing color-fastness of organic coloring matter

Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE           A method for increasing color-fastness of organic coloring matters  against  light  is disclosed.  the color-fastness of the organic coloring matter of which absoption maximum is the region from 400nm to 700nm is increased by coexisting with a metal complex represented by the following general formula:       in which R,, R2,  Rl' and R2' are a hydrogen atom or  a substituent, X and X' are O or S, Y is O, S, SO or SO2 and M is a metal atom.          The method adapts to improve the fastness of color images  of silver halide photographic materials.  In this case, the organic coloring matter is a dyestuff formed by coupling a color forming coupler with an oxidation product of a color  developing agent  in the silver halide color photographic material or a dyestuff diffused to a recieving layer of  the  diffusion  transfer  silver  halide  color photographic material.

Title: Mirror assembly for lasers
Inventor: PODGORSKI THEODORE J
IPC: G01C19/66
Filed: 1986-11-13
Granted: 1992-04-07
Abstract: ABSTRACT         A mirror chip and mirror assembly are disclosed for use with a laser, and specifically, a ring laser angular rate sensor.  The mirror chip includes a mirror material deposited upon a silicon wafer.  The mirror assembly includes the silicon wafer bonded to a secondary supporting substrate.  The mirror chip and supporting substrate are highly polished so that they may be bonded together by an optical contact bond.

Abstract: TITLE               A METHOD OF MANUFACTURING A FOUNDRY MOULD, OR A COMPONENT THEREOF     INVENTOR                              ERVIN I. SZAB?     ABSTRACT OF THE DISCLOSURE       A method of manufacturing an easily separable from cast-metal, foundry mould, or a component thereof, comprises, preparing a foundry mould mix by mixing a binder with sand in the range 20 to 50 L of the binder per M3 of the foundry sand, the binder consisting of an aqueous solution of glyoxal containing 20 to 40% glyoxal and at least one metal oxide condensing/ polymerizing enhancing agent (e.g. magnesium oxide, calcium oxide and zinc oxide) for the glyoxal, and then shaping a mould from the mix.  Preferably at least one metal halide (e.g.  zinc chloride, magnesium chloride, calcium chloride, manganese chloride and iron chloride) is included, preferably in the amount of about 1.0% of the aqueous solution of glyoxal to saturation, as a glyoxal condensation reaction augmenting additive.          The glyoxal condensation reaction augmenting additive may also be ferric oxide, manganese dioxide or red lead or mixtures thereof.
