Title: Improvements in or relating to cryogenic refrigerators
Inventor: PUNDAK NACHMAN
IPC: F02G1/057
Filed: 1989-05-25
Abstract: A cryogenic helium-filled close-cycle refrigerator comprising a compressor unit (1) which is connected by a gas passage (3) to an expander unit (2). A reciprocating displacer/regenerator (10, 11) is located in the expander unit (2). The regenerator (11) is exposed to a steep thermal gradient where its cold end is at the expansion member cryogenic temperature, and its other end is at a temperature which is above the ambient temperature. The displacer/regenerator assembly (10, 11), due to its cryogenic temperature, acts as a cryogenic pump and condenses all the gaseous residuals (other than Helium, Hydrogen and Neon) in the refrigerator internal volume. These residual gases, such as water vapors, air residuals, derivatives of the bearing grease, organic derivatives of the motor windings, and the like, when condensed in or around the displacer tend to affect and degrade the normal dynamic and thermodynamic functioning of the refrigerator. Absorbent materials like activated charcoal are added to the regenerator at an adequate amount and location, the gaseous contaminants then being controlled and their degrading effects eliminated. <IMAGE>

Patent GB-2239115-A (GB)
Title: Direct dividing frequency synthesiser
Inventor: UNDERHILL MICHAEL JAMES
IPC: G06F7/68
Filed: 1989-12-15
Abstract: A direct dividing frequency synthesiser comprises a dual modulus frequency divider (12) for dividing a clock frequency (Fc) selectively by an integer (n) or (n+1), where n is the integer part of the divisor (n+0.m). The output (Fin) of the frequency divider (12) is applied via a delay modulator (14) to a rate multiplier (16). In the rate multiplier (16) the frequency of the signal (Fo) is multiplied by the fractional part (n+0.m) of the divisor (n+0.m). An output of the rate multiplier (16) is applied to a modulus control input (18) of the frequency divider (12) and the state of a signal (Fs) on the modulus control input (18) determines whether the frequency division is by (n) or (n+1). A phase error circuit (20) is provided to derive phase errors based on the excess or accumulated value in the rate multiplier (16) and to provide phase error samples. The delay modulator (14) converts these samples to time displacements which are used to delay transitions in the signal (Fin) by an amount to remove jitter. <IMAGE>

Title: Automatic vehicle guidance systems
Inventor: JACKSON DOUGLAS
IPC: G05D1/02
Filed: 1990-03-07
Abstract: A method of controlling one or more automatically controlled vehicles (10) using beacons (14, 24) and receivers (13, 23) (beacons being fixed and receivers on vehicles, or vice versa) uses a sequential switching system such that the effects of malfunctioning or masked beacons (14, 24) or receivers (13, 23) can be allowed for. The beacons sequentially emit signals, intervals between consecutive signals being equal until all beacons have been caused to signal, then after a first pause time of a first integral number of intervals the beacons emit signals in reverse order, and after all the beacons have been caused to signal, after a second pause time of a second integral number of intervals, the steps are repeated. The first and second integrals differ by an odd number. The invention also concerns apparatus for carrying out the method.
Patent GB-2247691-A (GB)
Title: Coating glass involving coating with an incompletely oxidized undercoat
Inventor: TERNAU ROBERT
IPC: C23C16/453
Filed: 1990-08-31
Abstract: In order to prevent interaction between coating precursor material used for applying an upper coating stratum, and/or to facilitate modification of the optical or other properties of the coating as a whole, an oxide substratum of said coating ("the undercoat") is pyrolytically formed in an incompletely oxidized state by contacting the substrate in an undercoating chamber with undercoat precursor material in the presence of oxygen in insufficient quantity for full oxidation of the undercoat material on the substrate and in that such undercoat is overcoated with an upper coating layer while it is still in an incompletely oxidised state, and while the substrate is still hot, thereby to preserve such undercoat in an incompletely oxidized state. The substrate is preferably freshly-formed flat glass, eg hot float glass. Air is supplied to the undercoating chamber in order to introduce oxygen thereto and the undercoat precursor is selected to contain silicon for the formation of a silicon oxide undercoat on the glass, eg a silane. The examples refer to forming a coating of SiOx where x is approximately 1.8. The undercoat precursor material preferably contacts the glass at a position along the float chamber such that the glass has a temperature which is at least 50 DEG C higher than the temperature at which the glass would exit from the float chamber if no coating were formed therein, eg at least 400 DEG C. Nitrogen may be used as a substantially inert carrier gas and turbulence may be induced in the carrier gas stream to ensure intimate mixing of the carrier gas and the silane. As illustrated in fig 3 the supply line 7 feeds the silane introduced through venturi 9 and nitrogen introduced through venturi 11 onto the float glass ribbon 1, with 10, 12 being turbulence imparting constrictions. <IMAGE>

Filed: 1990-10-12
Abstract: A marine vessel has on its surface a number of electrodes to which varying potentials may be applied. Each pair of electrodes has, associated with them, an integrated circuit which is programmed so as to cause the electrodes to modify the boundary layer dynamics at least partly by a magnetic-electric effect. This facility enables turbulence to be reduced, may be used to prevent reflection of sound waves, to render passage of vibration to the seawater a minimum, or to impose a "false" acoustic signature on the seawater. The electrodes 12 may be set in one of many tiles 2 attached in an array to the hull. The tile includes a magnet 10 producing a field in the direction of arrow 11, orthogonal to current between electrodes 12 allowing a required force to be applied to the seawater/hull interface.

Title: Combining photographic film material and digital video signals
Inventor: RICHARDS JOHN WILLIAM
IPC: G11B27/034
Filed: 1990-11-15
Abstract: A system for combining a 60 field/s 2:1 interlace scan format digital video signal and 24 frame/s source material, such as film, employs a film scanner 144 to produce a digital video signal from a source film 140, a post-production system 156 for combining with that signal the 60 field/s 2:1 interlace scan format digital video signal (for example from a VTR 154 or camera 152) to produce a signal which may be output in 60 field/s 2:1 interlace scan format, or in 30 frame/s progressive scan format for recording on film 182. Motion interpolated compensation is employed at stages of frame rate conversion. In order to obviate the need for more than one stage of motion interpolated compensation between the primary sources and primary outputs. the post-production system operates on signals in 60 field/s 2:1 interlace scan format, and motion compensated interpolation is performed only during conversion (at 148) of the 24 frame/s 1:1 progressive scan format signal to the 60 field/s 2:1 interlace scan format. The conversion of the combined 60 field/s 2:1 interlace scan format signal to 30 frame/s progressive format (at 176) does not require motion compensated interpolation because the frame rate is unchanged. <IMAGE>
