Patent GB-478650-A (GB)
Abstract: 478,650. Fusible cut-outs. C.A.V.- BOSCH, Ltd., and GLASER, W. H. July 21, 1936, No. 20158. [Class 38 (i)] [Also in Group XXXVII] Means for indicating the blowing of a fuse a in a motor-vehicle electric system having a dynamo d, storage battery b, and indicator (lamp e) in the ignition circuit, comprises an electromagnetically-operated switch, the winding h of which is connected across the fuse a, and the contacts g of which control alternative circuits through the indicator. Closure of hand-switch f which also controls the ignition circuit, lights lamp e until the cut-out c operates. If, while c is closed, the fuse blows, winding h is energized to attract contact g, which changes the lamp connection from dynamo + to battery-, so lighting lamp e. The fuse may, alternatively, be connected between cut-out c and dynamo +, Fig. 2 (not shown). A resistance k prevents excess current at battery-voltage from damaging winding h, current from the dynamo being diverted through rectifier l.

Title: Starter switch for starting a discharge lamp
IPC: H05B41/04
Filed: 1976-11-18
Abstract: 1533646 Starting discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1976 [21 Nov 1975] 48092/76 Heading H2H An arrangement for starting a discharge lamp 4 comprises a series circuit including a capacitor 7, a positive temperature coefficient resistor 8 and a bidirectional thyristor 10. When a mains A.C. supply is connected to the lamp, which may be a low-pressure mercury vapour lamp, a capacitor 14 is charged until a disc 16 breaks down thereby triggering the thyristor 10. Current flows through a circuit including the capacitor 7 and a ballast inductance 6 which supply a high voltage to the electrodes 3, 5 of the lamp. The lamp ignites and the voltage across it falls to a value which is too low to cause further breakdown of the diac 16. If the lamp fails to ignite the current through the resistor 8 and the thyristor 10 heats the resistor thereby greatly increasing its resistance so that the current is reduced until it is insufficient to maintain the thyristor 10 conductive. The lamp may have pre-heatable electrodes.

Title: Image darkness discrimination
IPC: G06V10/28
Filed: 1974-11-11
Abstract: 1484915 Character recognition systems FUJITSU Ltd 11 Nov 1974 [9 Nov 1973] 48759/74 Heading G4R A system, for example for use in character recognition, develops signals each representative of the state, black or white, of a corresponding elementary area of a scanned image field. For each elementary area (centre area) a first value is formed representing the sum of the density (darkness) of that area and of each of a certain number of areas surrounding that area. The sum of the densities of a group of adjacent which excludes the centre area is formed in respect of a number of such groups surrounding the centre point. The largest of these sums represents a second value, which is compared with the first value to decide whether the centre area is to be regarded as black or white. In the disclosed embodiments the first value is derived from a 3 x 3 matrix of areas, and each group consists of a 2 Î 2 matrix of areas contiguous to the centre area. The image field is scanned by, for example, a columnar array of photosensors, a flying spot scanner, or a rectangular array of photosensors which covers the field. Except in the latter case the serial scanner output passes to a quantizer (Fig. 4, not shown) which quantizes the signal into 8 density levels. The reference black and white levels in the quantizer are varied according to slow variations in the density of the image and background. The quantizer output levels are converted to 3-bit signals which pass to a store comprising serially-connected shift registers so that the image is, in effect, rolled through the store. Certain cells of the registers are connected to summing circuits (Figs. 10 or 12, not shown) to develop the various sum signals, referred to above, in respect to each field area in turn as the image passes through the store. The density value of the centre area may be weighted prior to summing. The largest of the group sums, the second value is biased upwards if it is large and therefore indicative of high density, and is biased downwards if it is low, before being compared with the first value. This has the effect of ensuring that transitions in the comparator output more accurately correspond to the edges of the image, despite fuzziness of the edges of the scanned image (Figs. 16A-16C, not shown). If the first value exceeds the second the centre area under consideration is deemed to be black. If the scanner comprises an array of photosensors covering the field its analog output, suitably clocked, is passed direct to the summing circuits.

Abstract: 1,092,968. Testing cigarettes. HAUNIWERKE KÍRBER & CO. KOMM.-GES. Nov. 7, 1966, No. 49717/66. Heading A2C. -In a method for checking the wrappers of rod-like articles having a filling and an enclosing wrapper such as cigarettes, filter cigarettes and filter rods, the pressure or flow of a gaseous medium, such as air, applied to the article is compared with a different pressure or flow not dependent on the properties of the wrapper, and the difference utilized to distinguish acceptable articles from unacceptable articles. A cigarette Z is transferred to a checking drum 2 on which it is held in grooves by suction in known manner after compressed air fed through a port 88 into a chamber 78 has moved a piston 58 to the right (as shown in Fig. 1) against a spring 116 to press the cigarette Z against a stop 8. Compressed air is then fed into a duct 32 and thence via passages 30, 28 having adjuster screws 38, 40 to chambers 50, 52 respectively either side of a control piston 48. Chamber 50 leads to a calibrated reference nozzle 90 venting to atmosphere, and chamber 52 leads to ducts 76, 70 and thence to one end of the cigarette Z. Where the wrapper of the cigarette Z is acceptable, air loss through the nozzle 90 and the wrapper is balanced and the piston 48 remains in the position shown. The greater loss of checking air when a cigarette Z has a faulty wrapper, reduces the pressure in chamber 52 causing control piston 48 to move to the right and vent the chamber 78 enabling piston 58 to be returned to the left by the spring 116 and its cylindrical mouthpiece portion 68 to disengage the faulty cigarette Z. The faulty cigarette Z is then rejected by removal of the suction holding it to the drum while applying compressed air through a duct 10, the normal cigarettes Z being retained meanwhile by their non-retracted mouthpieces 68.

Abstract: 996,235. Rotary fluid motors. R. H. BURGESS. Dec. 17, 1963, No. 49824/63. Heading F1F. [Also in Division B2] A device utilising the kinetic energy of a fluid to produce rotary motion, comprises a stator and a rotor defining between them an annular space whose radial width is restricted over a portion of its axial length, the rotor being mounted to be freely rotatable about the stator axis and free to tilt about a point on or close to said axis with the fluid passing through the annular space to cause rotor rotation. In Fig. 8, a rotor R having a flange at its upper end providing a restriction over a portion of its length, is supported in a stator S on a pivot pin 25 which at its lower end is supported on a ball-bearingly supported plate 22 having a hole therethrough engaging a pin 21 fixed to the rotor R. Initially the rotor R cants over and rests at one point against the stator bore. Pressure fluid admitted to the stator at its top passes through the restriction between the rotor and stator and immediately it passes its pressure is reduced. It is stated that this reduced pressure draws the rotor top across the gap, the reduced pressure gradually working around the gap to cause the rotor to commence rotating. In a practical application, a rotor 91, Fig. 17, is supported on a plate 96 by means of a pivot 101. A pin 98 on the rotor engages a slot in the plate 96, which on the admittance of compressed air through an inlet 102 in the stator 92 causes the rotor to rotate to drive an output shaft 95. Other embodiments (see Division B2) applicable to water sprinklers are described.
