Title: Method for specifying colours for colour printing.
Inventor: KEENES ASHLEY
IPC: B41F33/00
Filed: 1991-06-06
Abstract: A method for specifying colours comprises imprinting a series of equal sized bars of the colours black, cyan, yellow and magenta at colour loadings of from 5% to 100% in 5% steps onto respective sheets of transparent material, e.g. polyvinyl, polyester or polyacetate material, overlaying one or more sheets such that imprinted areas overlap to provide a specific colour moving one or more of said sheets relative to the other sheets until a desired colour is obtained and then specifying the colour by reference to the respective colour loadings of the imprints forming the said colour. <IMAGE>

Patent GB-2251096-A (GB)
Title: Loop power supply circuit
Inventor: EPTON DAVID JOHN
IPC: H02M3/156
Filed: 1991-11-06
Abstract: A power supply circuit is arranged to minimise the voltage drop around a current loop for a given power supplied at a defined voltage. The circuit includes a regulator IC2, 18, TR2 powered from the current loop and arranged to provide a power supply output. The regulator has a negative resistance type characteristic such that as the loop current increases, the voltage drop decreases, so that the power taken from the loop is substantially constant. This is achieved by adjusting the mark-space ratio of a voltage enhancement switching regulator to maintain a constant voltage. Operational amplifier IC2 senses the output voltage and adjusts the mark-space ratio of oscillator pulses fed to a transistor TR2. A charge pump circuit may also be used. <IMAGE>

Title: Phasmid vectors
Inventor: DWARAKANATH PRAHALAD
IPC: C12N15/70
Filed: 1991-11-20
Abstract: Cloning and expression vectors comprise (i) a replication origin and morphogenetic signal sequence derived from filamentous bacteriophage of E.coli having F pili (f1, M13, fd) and (ii) aT7 (T7 O 10) phage promoter upstream of a multiple cloning site. The vectors carry an antibiotic resistance marker gene ampicillin (pARC032 and pARC035) or Kanamycin (pARC036) and a bacterial origin of replication pARC032 and pARC035 are identically constructed except the f1 replication origin sequence lies in opposite orientation. Upon transformation of E.coli male specific strains with phasmid containing a recombinant insert, is plasmid DNA packaged as a viral particle can be produced when the transformants are superinfected with a helper phage. This ss phasmid DNA can also be used as template for ss DNA sequencing and in vitro site directed mutagenesis. Genes inserted at the multiple cloning site of the phasmids can be expressed in appropriate host strains. <IMAGE>

Title: Assembly of a pressurized fluid motor with multiple cubic capacities and of a brake associated therewith
Inventor: ALLART BERNARD R
IPC: F16D55/40
Filed: 1992-03-04
Abstract: A drive assembly comprising a fluid motor 1 and a brake 2 is controlled by a slide 29 which may be used to select the required cubic capacity of the motor 1. According to the invention, the large cubic capacity of the motor 1 can be selected only when the brake 2 is in its brake-release configuration. Accordingly the slide 29 is resiliently urged to select the small cubic capacity by a spring (63, fig 2); only when the pressure in the brake-release chamber 41 equals a brake-releasing pressure, can fluid act via a conduit 57 to move the slide 29 to select the large cubic capacity. A chamber (59, fig 2) situated at the opposite end of the slide 29 to the conduit 57 can be connected to a high pressure source in order to select the small cubic capacity when the pressure in the brake-release chamber is equal to the brake-releasing pressure. <IMAGE>

Title: Heat sensitive-recording medium
Inventor: OSAWA HARUHIKO
IPC: G06K19/06
Filed: 1992-05-20
Abstract: A heat-sensitive recording medium comprises a substrate (1), a contrast enhancing layer (2), a thermally fusible layer (3), a thin metal layer (4) for forming visible information by being partially melted according to a desired pattern, a reversible thermal recording layer (5), a protective layer (6) and, optionally, a printed layer (7) between layers (5) and (6). When heated by means of a thermal recording head, visible information is formed in the thin metal layer (4), and also in the reversible thermal recording layer (5) due to changes in the degree of its optical transparency from the transparent state up to an almost opaque cloudy state, and retains its state after being cooled dawn so that desired visible information can be recorded on the layer. Therefore, according to this recording medium, re-writable information and unre-writable information can be recorded on a desired area by heating so as to cope with various applications of the visible information recording medium. Layer (5) preferably comprises a polymer and a C10-30 fatty acid or salt, ester or amide thereof. <IMAGE>

Patent GB-2268653-A (GB)
Title: Optical distribution system
Inventor: O'NEILL FRANK P
IPC: H04B10/12
Filed: 1992-10-05
Abstract: A downlink portion (10) consists of a multiplexer (11) for combining several signals. The combined signal is converted to an optical signal by a laser (12) and transmitted over an optical line to a splitter (13). The split signals are each transmitted to a detector (14, 14') which converts the optical signals back into an electrical signal. The electrical signal is then filtered (17, 17') to provide the desired signal from the combined signal. The desired signal is then transmitted. The uplink portion consists of a plurality of receivers (71,72) which receive signals from remote units. The received signals are multiplexed and converted to optical signals in a laser (73,74). The optical signals are transmitted over optical lines to a combiner (75) which provides a single combined optical signal. The combined optical signal is then transmitted over optical lines to a detector (80) which converts the optical signals to an electrical signal. The electrical signal is then demultiplexed into its constituent portions.

Filed: 1994-10-04
Abstract: Apparatus for applying liquid or gel to hair. Grooming apparatus comprises a housing with an inner (2) and outer (1) casing, an elongate handle (21) and comb elements (11). Two cylindrical foil cartridges of concertina construction (3, 4) which contain dye colour base and dye colour developer lie in the inner casing (2). An elongate plunger rod (7) carrying rupture elements (5, 6) and spike projections connected to a plunger handle (8) extends along the inner casing (2). The hair treatment material is released by pumping the plunger handle (8) which causes the cartridges to compress and rupture. Continued pumping mixes the dye components. The dye is released from the inner casing (2) to impregnate a pad (12) of expanded polystyrene. Comb elements (11) extend downwardly from the pad. The dye contacts the hair either by touching the pad (12) or by seeping down the comb elements (11). The dye may be prevented from impregnating the pad by rotating the inner casing from an "on" position to an "off" position. <IMAGE>

Abstract: An electronic component or assembly has incorporated therein means capable of providing identification of the component or assembly on interrogation. The arrangement may be applied to, for example, printed circuit boards, circuit modules, integrated circuits, memory modules and assemblies including such components. The identification means may be a discrete element inserted and sealed into a recess in the component or may be surface mounted on the component. Alternatively, the identification means may be an element functionally separate from the component but fabricated as part of it. The identification means may be manufactured such as to provide an identity or may be programmed subsequently. The identification means may be a transponder interrogated by direct electrical contact or by a radiated radio frequency signal and it may be powered by a dedicated local power source or by energy derived from an interrogating signal. Any tampering with the transponder may be indicated visually and may be arranged to render the electronic component non-functioning.
