Title: Image pattern selection and location method
IPC: G06T5/00
Filed: 1975-07-30
Abstract: 1525856 Recognizing images PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 July 1975 [2 Aug 1974] 31895/75 Heading G4R The invention relates to generating density change contours on a two-dimensional picture and determining the position of a best match of these contours with a template contour, e.g. the outline of an object being searched for. An image such as an X-ray image of a heart is scanned using a television camera and the signal produced is sampled to produce a plurality of signals each indicating the optical density of an image point in the image. The signals are stored in a matrix store alongwith co-ordinate values indicating the positions of the signals in the store. A value representing the horizontal rate of change at each point is obtained by adding the density values of several matrix positions on one side of the point and subtracting this sum from the sum of the same number of matrix positions on the other side of the point (Fig. 1, not shown) and storing the result. The results are examined to determine the maxima and if these are above a threshold value they are replaced by a "1" value and the other values are replaced by a zero value to form a contour matrix. The subtraction may produce maxima with positive or negative signs and these signs can be stored with the "1" value as in Fig. 4 where the pattern indicated by squares is the contour from the image being examined and the solid squares indicate maxima with negative signs and the open squares indicate maxima with positive signs. A template 'or reference contour is indicated by the triangles. Separate memories may be used to store the positive and the negative patterns.  A distance matrix is produced by generating in a matrix store zero values at all locations corresponding to the contour determined from the radiograph as shown in the heavy line in Fig. 3. The adjacent memory locations are filled with a "1" value and the next adjacent locations with a "2" value and so on. Values in this distance matrix at points on the template or reference contour are then added to produce an out of register measure. The template contour is then effectively shifted and the process repeated to produce an out of register measure for each shift and the comparison with the lowest sum is taken to indicate the best match.

Title: Improvements in devices for regulating flow of fluids
IPC: G05D7/06
Filed: 1929-10-22
Abstract: 329,944. Hasemann, F. Oct. 22, 1929. Fluid-actuated valves.-In a sensitive control device for regulating the flow of pressure fluids through conduits of the type wherein regulation is effected by hydraulic and electromagnetic means under diaphragm control, the diaphragm 4 controls a pendulous contact 11 which co-operates with two contact springs 13, 16 supported on a frame 19 which also carries the armatures 15, 18 of the electromagnets 14, 17 and a relay slide valve 21 held by springs 22, 23, said slide valve controlling a hydraulic piston 29 whereby a regulating valve 2 is operated. The co-operation of the springs 13, 16 with the pendulous contact 11 energizes one or other of the magnets 14, 17 to actuate the slide valve 21 appropriately. A lever 7 carrying adjustable weights 8 floats between springs 9 and loads the diaphragm 4, the value of the weight 8 depending on the normal pressure in the conduit 1, and the springs 9 opposing the deflection of the contact 11 beyond a given angle. In operation, if the pressure in the conduit 1 is above normal the diaphragm 4 presses contact 11 against contact 13 which energizes the magnet 14 to pull the armature 15 towards it, thus moving the relay slide valve, which is supplied with pressure fluid through the conduit 25. Said pressure fluid then actuates the piston 29 so as to close the regulating valve 2. The contact 13 disengages from the contact 11 by the above movement and hence the spring 22 tends to return the slide valve 21 and the frame 19 to normal until the contact 13 again engages the contact 11 when the above operation is repeated. Thus the piston 29 and valve 2 are actuated intermittently until the pressure in the conduit 1 is normal. A rigid abutment 12 limits the movement of the contact spring 13, 16.

Patent GB-341142-A (GB)
Title: Improvements in or relating to shuttleless looms
IPC: D03D47/00
Filed: 1929-10-23
Abstract: 341,142. Shuttleless looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and HALE, F. C., of British Celanese, Spondon, near Derby. Oct. 23, 1929, No. 32196. [Classes 142 (ii) and 142 (iii).] Means for measuring weft from a stationary supply at the side of the loom in the form of a loop sufficient for two picks are used in combination with weft-inserting means adapted to engage each limb of the loop in turn and carry it part-way through the shed, and with means for transferring the weft thus inserted to withdrawing means adapted to carry it through the remainder of the shed. As shown, the loop-forming and measuring mechanism comprises an oscillating disc 13, Fig. 1, having two pairs of cam-actuated trapping and severing devices 14, 15 adapted to hold one end of the weft 11 from a supply 10 while a pair of pegs 16 on a reciprocating chain 17 draw a loop of weft sufficient for two picks past the other trap. ping device, which then closes to grip the weft, while the first trapping device releases its hold. After the first limb of weft has been inserted, a severing device 15 is operated to free the other limb of the loop of weft which is thereafter inserted in the shed. To ensure measuring the correct length of weft, a pin is adjustably mounted in the path between the pegs 16 on the chain to form a bight in the end of the weft loop. The chain and disc 13 are reciprocated by skew and bevel gearing from the crank shaft 21. When the loop has been formed, one limb is depressed into the path of a weft-inserter by an arm 45 operated by link and bell-crank mechanism from a cam 51 on a shaft 53 rotating at half crank-shaft speed. A fork 67, Fig. 3, of a weft-inserter 66, Fig. 3, then engages the depressed limb of the loop of weft and carries it halfway across the shed where it is engaged by the hook portion 68 of the weft-inserter that is advanced from the opposite side of the loom. Each weft-inserter has a guide-plate 70, and a guard 69 to prevent fouling of the warps. The inserted first limb of the weft loop is engaged around a tensioning finger 32 mounted on a spring slide so as to give way if engaged by the pegs 16 on the chain, and controlled so as to remain firm during the beat-up, but to yield under the influence of an adjustable spring 42 as the tension on the remaining limb of weft is increased due to the rotation of the disc 13. After weft has been inserted from the opposite side of the loom, the remaining limb of weft is inserted. Wefts may be inserted alternately from opposite sides of the loom, or in any desired sequence. The weft-inserters are reciprocated by links connected to camworked levers. Flexible metal weft-inserters of the kind described in Specification 342,253 may be employed. Beat-up motions.-A rapid beat-up is obtained from a cam 29, Fig. 1, mounted on the crank shaft 21, and of such contour that the lay 46 is retained in its rearmost position for the major portion of the revolution of the crank shaft, to allow sufficient time for the operation of the weftinserters.

Filed: 1969-06-26
Abstract: 1278629 Filtration process MAGYAR TUDOMANYOS AKADEMIA 26 June 1969 [30 Aug 1968] 32436/69 Heading BID A dilute suspension is filtered at a low differential pressure through one sector of a moving filter surface thereby obtaining a turbid filtrate and a deposit of solids on the filter surface which acts as a filter aid whereby a clear filtrate is obtained by applying a higher differential pressure to a further sector, into which the filter surface moves from the first sector, the turbid filtrate being recycled to the upstream side of the filter surface. Several turbid filtrates may be obtained at progressively increasing differential pressures, all being recycled. Turbid filtrate may be concentrated, e.g. in another filter, before recycling. Fig. 5 shows a vacuum drum-travelling band type filter 62-76, from which clear filtrate is discharged from one drum sector at 71 while turbid filtrate from an upstream sector (in direction of drum rotation) is recycled at 69 to a rotary disc vacuum filter 51 - 59. This latter is arranged to obtain turbid and clear filtrates from different sectors and also to deliver reverse flow liquid to one sector to clear the disc. The turbid filtrate and thickened slurry drawn from outlet 59 are returned to filter 62 - 76. The initial feed is by inlet 51 to the disc filter, and the final cake is discharged where filter band 72 passes round roller 74 and falls on to conveyor belt 75. Filter 62 - 76 has a stirrer 64. Fig. 3 (not shown) illustrates a rotary drum vacuum filter for performing the inventive process, with provision for obtaining two filtrates, discharging cake from the drum by reverse flow air, and slurry agitator (31). Fig. 4 (not shown) illustrates a rotary drum pressure filter, with two inlets delivering suspension to different sectors of the casing around the drum. Both pressure and vacuum are applied to respective filtering sectors and a scraper removes the cake. Fig. 2 (not shown) illustrates the fixed part of a rotary valve with an adjustable partition separating turbid and clear filtrate receiving sectors.
