Title: Pattern detection apparatus
Inventor: MCCARTHY BRIAN DENNIS
IPC: G06V10/24
Filed: 1968-01-17
Abstract: 1,221,071. Copying by scanning. NATIONAL RESEARCH DEVELOPMENT CORP. 9 Jan., 1969 [17 Jan., 1968], No. 2649/68. Heading H4F. [Also in Divisions G1 and G4] In an automatic boundary follower system (see Division G1) boundaries which are not sufficiently distinct are dealt with manually by a cathode ray tube display of the boundary and a light pen. Biological cells on a slide 21 in a microscope 23 are scanned by a flying spot scanner 1 and the emergent light is detected by a photomultiplier 26 to produce a display on a monitor tube 35. Non-uniform transmission of the microscope optics 23 is compensated by exposing a film to a uniform light source through the microscope and using the exposed film as at mask 24. 10% of the light from the flying spot scanner scans the mask in synchronism with the slide and the output of a further photomultiplier 25 is used to control the gain of amplifier 27.

Title: Colour television subcarrier oscillator arrangement
IPC: H04N9/455
Filed: 1972-01-20
Abstract: 1412416 Automatic frequency control; colour television MULLARD Ltd 15 Dec 1972 [20 Jan 1972] 2763/72 Headings H3A and H4F A colour TV subcarrier oscillator arrangement comprises: an automatic frequency control circuit in which an output from an oscillator is compared with a signal derived from the line synchronizing pulses of the TV signal to produce a correction signal for controlling the oscillator frequency; and an oscillator phase control circuit in which first and second quadrature subcarrier components, modulated with first and second colour signals respectively, are combined to produce a signal of twice subcarrier frequency and substantially constant phase which controls the phase of the oscillator output. Frequency control.-Oscillator 15 produces an output at twice the subcarrier frequency which is fed via an interrupter 20, which subtracts the field frequency, and dividers 21, 22 to give a first input to comparator 23 at half line frequency. A second input to the comparator, at half line frequency, is derived from the line oscillator 59 which in turn is provided with afc from a flywheel synchronizing circuit 58, 60. The comparator output is fed via LP filter 24 to control the frequency of oscillator 15. Phase control uses the " chroma lock " principle. The received modulated subcarrier at 1 is separated into B-Y and R-Y component phases by the adder and subtractor following delay 3 which are fed via frequency doublers 33, 34 to a combiner 35. The output from the combiner is fed to one input of a phase comparator 37, the other input of which is fed with the output from oscillator 15, and the comparator output is fed via LP filter 39 to control the phase of oscillator 15. Demodulation reference signal phase control.- Quadrature reference signals for the synchronous demodulators 4, 5 are derived by frequency dividing by two the antiphase outputs from oscillator 15, which may introduce ambiguity of 180 degrees in the output of dividers 16, 17. In order to allow for this, the R-Y and B-Y reference signals are fed to further phase comparator 43, 44 where they are compared with corresponding components of the received burst signal. The output from the comparators 43, 44 are then fed back to control inhibit gates 49, 50 to correct the phase. The two comparator outputs may also be combined to provide colour killer and automatic colour control signals. In an alternative arrangement, Fig. 2, correction of the 180 degree ambiguity is provided by a modified chroma lock circuit, in which the comparator 37 is preceded by a changeover switch operated at line frequency, and the outputs from the dividers 16, 17 are multiplied in multiplier 55. In one position of switch 57 the output from combiner 35 is compared with the output from multiplier 55, and in the other one of the reference subcarrier signals, i.e. that from divider 16 is compared with one of the received subcarrier signals. Reference has been directed by the Comptroller to Specification 1,070,193.

Abstract: 1,052,831. Plastic shortenings. PROCTER & GAMBLE CO. Jan. 22, 1965 [Jan. 24, 1964], No. 2922/65. Heading A2B. [Also in Division C5] Plastic shortening compositions suitable for frying and baking consist substantially entirely of fatty glyceride, and comprise 0.2-1.0 wt. per cent. based on the whole composition of one or more C 12-22  fatty acid monoesters of polyoxyethylene sorbitan containing an average of 20 oxyethylene units per molecule; with or without further additives in an amount of up to 10% of the whole. The sorbitan derivative may be acidified, e.g. with H 3  DO 4 , H 2 SO 4  or HCl, or by passage through an acid activiated filtering clay; alternatively a small amount of acid may be added to the shortening. The fatty glyceride may be any conventional triglyceride, a di- or tri-glyceride containing one or two C 2-6  fatty acid residues, a mono- or di-glyceride prepared by reacting a trigylceride with excess glycerine, or a rearranged or interesterified fat, any of which may, where necessary, be partially hydrogenated to a plastic state. The shortenings preferably contain 0.01-0.25% of a water-soluble salt of a phosphoric acid, e.g. sodium mono-, di-, or tri-basic phosphate, tetra-Na or K-pyrophosphate, sodium glycerophosphate, or Graham's salt. Other optional additives include emulsifiers, e.g. partial fatty acid esters of dihydric alcohols or sugar alcohols; antioxidants, e.g. butylated hydroxy - toluene or anisole, or methyl silicone; flavouring; and colour. In examples, the shortenings are used in the baking of white, yellow and chocolate cakes with otherwise conventional ingredients.

[Class 100 (iii).] Moulds.-Relates to means for adjusting the position of the moulds on the mould-disc in order to secure registration with the trimming- knives in spite of displacement due to warping of the mould-disc or other causes. The moulds, instead of banking directly on the walls of the pockets in which they are mounted, are supported by adjustable interponents, which are preferably in the form of eccentricallymounted pins. Each mould is, as heretofore, held in position in its pocket by retaining- screws A<8>, Fig. 1, and is pressed downwards by overhead binding-screws B<5>. The mouldbody A<1> carries three rotatable pins, one D being mounted at each end of the mould, and the other D<1> at the centre. The pins have screw-heads to facilitate their rotation, and have at their rear ends eccentric portions D<3>, Fig. 3, which are adapted to rest on the lower wall B<2> of the slot in the mould - disc. The eccentric portions of the pins are as long as the supporting-surface B<2> is wide, and they are located directly beneath the screws B<5>, so that the pressure of the screws is transmitted directly to the mould-disc. The head of the centre pin D<1> is seated in a recess A<9> to enable it to clear the ears of the matrices. The end pins D are locked against rotation by setscrews D<4>, and the centre pin by a screw D<5> having an enlarged head to engage a flange on the pin.

The ordinary warp threads are operated by heald shafts 2 controlled by dobby levers 3 of an ordinary dobby having a cylinder driving- shaft 5 and a shaft 4 for the knives carrying the dobby catches. The auxiliary jacquard is driven in unison with the dobby and comprises horizontal lifting wires 23 having hooked ends 23<1> for engagement by a horizontally guided lifting-knife 20 arranged on sliding blocks 16, 16<1> operated by lever mechanism 15, 14 from a shaft 11, which is driven by lever mechanism from the dobby shaft 4. A transverse rod or counter knife 21 operated from the shaft 11 is loosely embraced by hooked parts 23<11> of the wires 23 and returns them to their initial position. The wires are selected for operation by the knife 20 by needles 28<1> passing through a needle board 28, which is periodically raised by arms 30 on a shaft carrying a cam lever 32 oscillated by a roller 34 carried by an arm on the dobby shaft 4. The needle board is raised to allow for the intermittent rotation of the jacquard cylinder 27, which is driven from the dobby shaft 5. The needles which engage holes in the operative card on the cylinder allow the corresponding wires to fall into engagement with the knife 20, whereby these wires are operated and the corresponding selvedge healds are raised. The wires 23 are guided by vertical pins 36, 37.
