Title: Character thinning apparatus
IPC: G06V30/10
Filed: 1973-12-21
Abstract: 1487920 Character thinning systems MULLARD Ltd 1 Nov 1974 [21 Dec 1973] 59463/73 Heading G4R The system includes means to apply a compound operator to each elementary area of a character represented as a matrix of such areas, the compound operator logic determining whether or not that area can be changed to represent background without breaking connectivity or creating a hole. The compound operator comprises a set of various of the operators described below. In the Figs. "0" represents an elementary area or point of background, "1" an area or point of the character and P the area or point currently under consideration. Fig. 38 represents an operator applied to a group of 9 points of the character matrix. Point P can be made a background point if one or more of the points 7 is as shown and the remaining points are all 0. Fig. 39 represents an operator which allows P to be made background if one or both of the points 8 are 1 and the remainder areas shown. Figs. 40 and 41 show two further operators which allow P to be made background if the other points are as shown. The state of the points diagonally adjacent P and shown blank is immaterial. Each operator is used in each of its four possible orientations. The compound operator includes the operators shown in Fig. 39, provided that at least one of the points 8 is 1, and in Figs. 40 and 41. In two of the orientations of the operator shown in Fig. 41 the operator is extended by a 1-point orthogonally adjacent the centre 1-point of the side containing three 1-points. The compound operator may also include operators, some of which may include extensions in certain orientations, selected from three further forms of operator. The point P is changed to background (0) if any one of the operators forming the compound operator is satisfied. A second compound operator, which may cause erosion of the ends of the limbs of a character, may also be used. A thinning operation may comprise one or more applications of the second compound operator followed by one or more of the first compound operator. The compound operators may be realized by logic circuits (Figs. 47, 48, not shown) or by a read-only memory addressed by the bits of the operator matrix (Fig. 49, not shown). As the thinning by the compound operators may leave portions of the character limbs two points wide an additional operator (Fig. 43, not shown) may be applied to reduce the limbs to single point thickness. Should the character not be sufficiently thinned after a preset number of applications of the compound operators it is rejected as being initially too thick. Inadequate thinning is detected by monitoring the operator in Fig. 41 during its final application: if it indicates that a point is to be made background the character was too thick.

Abstract: 1,235,766. Discharge apparatus generating oscillations; S.C.R. pulse generating circuits. PUROMATIC Inc. 30 Dec., 1968, No. 61774/68. Headings H3B, H3T and H5H. Ionized fluid is produced by passing fluid through a capacitor 26<SP>1</SP>, 27<SP>1</SP> connected to the secondary 45<SP>1</SP> of a transformer, the primary 47<SP>1</SP> of which is supplied with a succession of pulses each of which induces a damped oscillation in the resonant circuit comprising the secondary 45<SP>1</SP> and capacitor 26<SP>1</SP>, 27<SP>1</SP>. In the ozonizer shown capacitor 49<SP>1</SP> is charged by a voltage doubling circuit 56, 63 fed from an A.C. source 5. The capacitor 49<SP>1</SP> is discharged through transformer primary 47<SP>1</SP> by a parallel thyristor 66 which is fired under the control of a fixed frequency oscillator consisting of a neon tube 70, a capacitor 77 and a resistor 72. The thyristor 66 is switched off when the capacitor 49<SP>1</SP> has discharged to a certain value. The trigger frequency of thyristor 66 may be controlled by a variable frequency generator whose frequency is dependent on the demand for ozone determined by a flow detector. Each capacitor element comprises an insulated rod electrode 30 mounted in insulating discs in a tubular electrode 29, disc 33 being perforated to allow air to be supplied. The elements are electrically and physically connected in series by a pipe 38. The ozonizer is used for sterilizing a swimming pool as shown, but may be used for deodorizing sewage, oxidation in chemical processes, or for purifying containers, and machinery in the drug and food industry.

Abstract: 737,791. Spray-producers. PYRENE CO., Ltd. Aug. 25, 1953, No. 21300/52. Class 69 (3). Liquid forced from the outlet of a pipe 1 strikes a conical deflector 4 slidably mounted on studs 3, and the liquid is spread radially outwardly in spray form over a rim 12 with radial slots 13. The slots are of greater radial depth than width, and vary both in depth and in the inclinations of their bottoms to the deflector axis. An adjustable spring 7 surrounded by a guard 14 is located between a fixed cap 8 and the deflector, and the latter is urged towards the pipe outlet and closes it when the device is inoperative. The spray cone from the deflector may strike the inner wall of a surrounding hood to reduce the particle size. Two or more such devices may be fed from a common supply pipe.

Title: Electric circuit device and pendulum unit incorporating such devices
IPC: H03G11/08
Filed: 1978-08-01
Abstract: An electrical circuit device comprises an integrating amplifier arrangement that provides a circuit output signal in response to an input signal from a differential amplifier. The differential amplifier receives at one of its input terminals the circuit input signal e1 and at its other input terminal the circuit output signal e3. e3 will never assume a constant value but may only be either a positive or a negative ramp of fixed slope, oscillating about a mean for constant e1. Thus the circuit limits its output signal to change at less than a predetermined rate, and the device is particularly useful in a pendulum unit of a gyrocompass, where the rate limitation can be arranged such that the compass does not respond to acceleration due to motion of the craft or vehicle in which the compass is mounted. <IMAGE>
