Title: An illuminated vehicle registration plate with a halo effect
Inventor: GOGGIN PAUL
IPC: B60R13/10
Filed: 2009-10-30
Abstract: A vehicle registration plate in which the opaque characters can be back-lit against their opaque backgrounds in such a way as to form a halo of high intensity light around each character, which fades in intensity gradually from the character edges to the perimeter of the plate face, thereby enhancing the aesthetic appearance of the plate and its readability; and a means of manufacturing same. The registration plate comprises several layers laminated together. An outer layer 5 is a protective transparent sheet with clear adhesive on its inner surface. Below this black 4 and white/silver 3 opaque alphanumeric characters are sandwiched against a 6mm thick transparent sheet 2. The final layer comprises a retro-reflective film with the same alphanumeric characters cut from it, said characters having a smaller stroke than the black and white/silver layers. The plate is illuminated from behind, possibly by means of strips of LEDs, with the light passing through the gaps in the rear retro-reflective film, reflecting back off the white/silver characters, before passing backwards to the retro-reflective film which reflects it back towards the viewer around the black alphanumeric figures (figure 5). The registration plate is enclosed within a lighting enclosure (7, figure 4).

Abstract: 405,481. Gas holders ; fluid-flow-regulating devices. HAACK, W., and HAACK, A., (trading as HAACK, P.), 4, Garelligasse, and HOHL, H. 0., 29, Scheidlstrasse, both in Vienna. April 3, 1933, Nos. 10018 and 10019. Convention dates, May 17, 1932 and Feb. 20, 1933. [Classes 54 and 135.] An apparatus to be used in combustion analysis, calorific tests of gases, &c. for supplying gas at a constant pressure either above or below atmospheric comprises a vessel 1, Fig. 1, containing the gas communicating by a pipe 5 with a vessel 9 containing liquid, the vessel 9 being fitted with a cover 10 carrying an escape valve 14 and a pipe 12 provided with a stop cock 11 communicating with the atmosphere. The pipe 5 at its lower end is fitted with an upwardly opening flap valve 6 and is connected through an upwardly opening flap valve 8 to a branch pipe 7 terminating near the cover 2 of the vessel 1. At starting, the vessel 1 is filled with liquid through the open top of the vessel 9 and pipes 5, 7 until the liquid overflows at a pipe 4 leading from the cover 2. The stopcock 3 on the pipe 4 is then closed and liquid is added to the vessel 9 until its level is above the bottom of the pipe 12. The cover 10 is then applied to the vessel 9 and the vessel 1 is charged with gas through the pipe 4 until nearly all the liquid has been forced into the vessel 9, the displaced air escaping past the valve 14. The cocks 3, 11 are next opened and gas is allowed to escape until air bubbles enter the liquid at the lower end of the pipe 12. The gas remaining in the vessel will then issue from the pipe 3 at a constant pressure equal to the head of liquid due to the difference of level H between the bottom of the pipe 12 and the top of the pipe 7. The pipe 5 may be flexible to allow variation of the constant pressure. In alternative methods of charging, a vacuum may be produced in the vessel 1 by connecting a vacuum-pump to the valve 14 or by lowering the vessel 9 to below the level of the vessel 1. In a modification the pipe 7 surrounds the pipe 5 and is filled with the non-return valve at its lower end. In a further modification shown in figure 4 the pipe 5 is surrounded by a pipe for dipping into mercury 18. When the vessel 1 is being charged with gas the liquid level in the pipe 7b will fall below the surrounding liquid and the pipe 7b will then rise above the mercury and allow the liquid to flow under its lower end.

Title: Improvements in scanning oscillators for television receivers
Inventor: SMITH ROBERT BRUCE
IPC: H04N5/12
Filed: 1951-05-01
Abstract: 702,449. Automatic frequency and phase control systems. MURPHY RADIO, Ltd. May 1, 1952 [May 1, 1951], No. 10206/51. Class 38 (4) When a television receiver is first switched on, or after an interval in the transmission, the sync signals may be unable to lock-in the frequency of the scanning oscillator. This difficulty is met by rectifying the sync signals and thereby charging a condenser which is capacity-coupled to the grid of a reactance valve associated with the oscillator. The oscillator frequency is thus swept over a range until the normal phase discrimination takes hold and locks the oscillation. The scan oscillator is controlled by the output 3 of a sine-wave oscillator valve 2 back-coupled to an oscillatory circuit comprising transformer primary 22, condenser 23, and resister 24. A reactance valve 4 is connected across the tuned circuit, and its cathode circuit includes the resistor 24 thereby inducing a quadrature voltage into the gridcathode circuit. The reactance of the valve 4 is varied by including in its control-grid circuit the resistors 6 which constitute the load resistors of a pair of diodes 5. These diodes operate as a phase compressor, being fed on the one hand by amplified sync signals from the sync separator valve 1, and on the other hand with opposed phases supplied from the oscillator by the secondary coil of the transformer 7. In this way synchronism is maintained when once set up. At starting, however, the error may be too large, and the invention provides that the initial sync pulses at the anode of the valve 1 are applied to a diode 11 to charge a resistance-shunted condenser 13. The initial sync pulses cause increments of voltage on the condenser 13 which are transferred through condenser 14 and resistor 15 to the grid of the valve 4, thus giving a frequency sweep to the oscillator 2 until the oscillator locksin with the sync signals. The output of the oscillator may be applied through a condenser 16 to a further diode 12 shunted by load resistors 17, 18. Resistor 17 supplies a steady bias to the grid of the reactance valve through a smoother 20, 21 ; and both resistors supply a transitory bias through the condenser 19 and resistor 25, when the oscillator starts up. In this way a frequency sweep is provided, even if the oscillator starting is delayed until the sync signals have reached a steady state. Specification 443,423, [Group XL], is referred to.

Abstract: 527,155. Packages. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. April 1, 1939, No. 10208. [Class 94 (i)] Relates to a package of the kind formed by wrapping a blank of paper, foil, or similar material about an article, such as a charge of tobacco or a batch of medicinal tablets, into tubular form with portions 12, 13, Fig. 2, of the blank adjacent the two edges overlapping on the top of the packet. According to the invention, a rectangular blank 1, Fig. 1, has two sets of perforations 2, 3 lying parallel with the longer sides and separated by a distance slightly less than the length of the finished package, the outer ends of the perforations 2 being joined by a slit 6. When the package is completed, by apparatus of the kind described in Specification 419,950 for example, the edge 7 near the slit 6 lies under the edge 8, as shown in Fig. 2. The package can be closed by a seal and inserted in a tin box 21, Fig. 5. The package is opened by tearing the top flap 13 along the perforations 3, and then tearing the inner portion 12 from the slit 6 'along the perforations 2. The contents of the package are exposed but the structure of the package is not destroyed. In a modification, the perforations 3 are joined by a line of perforations parallel with the edge 8, so that a part of the top flap is removed when the package is opened.

Abstract: 908,936. Valves. RECHERCHES ETUDE PRODUCTEN. March 24, 1959 [March 24, 1958], No. 10221/59. Class 135. A piston valve, particularly for servo regulators, has a seat for the piston valve member comprising abutting annular elements some of which are slotted at abutment faces thereof to provide valve ports for co-operating with spaced lands of the valve member, the seat elements being assembled in abutting relationship into a sleeve having corresponding lateral ports opening into outer peripheral channels of the sleeve which sleeve is adapted for location in a bore of a valve body so that the outer peripheral channels register with flow passages of the body. As illustrated, the seat comprises a central element 13, two end elements 15, and two intermediate elements 14. Both end faces of the central element and one end face of each outer element are grooved at 16, 17 respectively to provide valve ports for co-operation with three spaced lands of a piston valve member 1, the spacing and widths of these lands together with the individual lengths of the elements 13 and 14 being determined to precise dimensions by the use of the same standard gauge blocks in their manufacture. The elements are assembled on a mandrel (not shown) and shrunk tightly into a sleeve 3 which has corresponding lateral ports 10, 11, 12 opening into outer peripheral recesses 7, 8, 9 which register with flow passages (not shown) of a servo regulator valve body 4 having a bore in which the assembly comprising the seat and sleeve is located by end members 6. Sealing rings 5 are provided on the sleeve.

Title: Improvements in optimised spatial filters which may be used in non-coherent or coherent light
IPC: G02B27/46
Filed: 1968-03-01
Abstract: 1,210,876. Spatial filtering. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. March 1, 1968 [March 2, 1967], No.10232/68. Heading G2J. In a spatial filtering arrangement in which a filter selects a useful signal s (x,y) of a known object from a crowd of objects b (x,y) in a scene g (x, y), the filter is weighted with a function representing the spectral density of the noise b (x, y). This may be done by illuminating a transparency forming the noise b (x, y) by a parallel beam of coherent light and placing photographic film as a negative in the focal plane of a convergent lens, the γ of the film being two so that the co-efficient of amplitude transmission t (p, q) of the film equals the reverse of the square of the amplitude distribution of the Fourier transform of the noise. The transparency carrying the filter structure w (x,y), Fig.4, is then placed in the front focal plane of the first lens L 1  of an assembly of two lenses L 1 , L 2  spaced apart by their focal lengths f to produce double diffraction, and the film t (p, q) is placed in the common intermediate focal plane P2 to produce a weighted filter in the final focal plane P3. To obviate difficulty in choice of γ for the negative and positive film a flat reference wave is produced at the intermediate focal plane P2 either by an interferometric assembly or small source hole, N # (p,q) centred on the plane P2. Linearity is then achieved between the amplitude distribution in plane P3 and the coefficient of power transmission of the weighted filter produced when the film is exposed at plane P3. Such a filter is usable in coherent or non-coherent light.

Abstract: 1,63,774. single lens reflex cameras. PENTACON DRESDEN KAMERA-und KINOWERKE, VEB. March 11, 1964, No. 10272/64. Heading G2A. In a single lens reflex camera, on pressing the cocking lever 22 the mirror 24 is moved into the viewing position, and a spring 21, acting through lever 20, presses a plate 19 forwardly, carrying with it, through pin and slot coupling, a setting member 17 so that setting lever 5 is rotated against the action of spring 6 and diaphragm blades 3 are moved into their fully open position. To adjust the diaphragm, pre-selector ring 8 is moved rearwardly against the action of springs 13, and pin 14 released from one of a series of notches 15. Simultaneously, ring 8 forces plate 19 rearwardly and spring 18 urges setting member 17 into contact with a cam 12 rigid with ring 8 and a switch 29 in the circuit of photo-cell 27 is closed, so that diaphragm blades 3 may be adjusted until needle 31 of meter 28 is aligned with a pointer 32 settable for the exposure time. On releasing ring 8, pin 14 engages the appropriate notch 15 to pre-select the diaphragm opening and member 17 is once more urged forwardly to fully open the diaphragm. When release button 26 is depressed, spring 23 rotates cocking lever 22 so that the mirror 24 is pivoted away from the viewing position, spring 21 is untensioned and the relatively weak spring 6 thus enabled to move member 17 into contact with cam 12 and set the diaphragm to the pre-selected position. In a modification, Fig. 2 (not shown) the pre-selector ring (40) is provided with a lever (37) which normally engages one of a series of notches (15) and, on release, simultaneously pivots a rocker (38), which engages plate (19), and closes the photo-cell switch (47).
