Abstract: 1400404 Scanning surface impurities IMAGE ANALYSING COMPUTERS Ltd 19 July 1972 13590/71 Heading G1A [Also in Division G4] Surface imperfections on a sheet of polished steel are scanned by a C.R.T. and a ratio of the total number to the number occurring within a certain region is obtained. The resulting amplitude excursions are sent to a threshold detector to derive signal pulses whereby the imperfection is detected, each signal pulse being taken to a monostable circuit where a pulse of length Wl is emitted, the lengthened pulses are taken to a further circuit which emits a single pulse at the end of the time WI on the first clear scanning line after the set of signal pulses indicative of the impurity, which pulse is sent to a looped circuit comprising a bi-stable and delay devices where a pulse of length W2 is caused to be recycled in synchronism with the scan, its trailing edge coinciding with the position of the pulse in each like period there being a gate in the loop circuit which is closed by an output from a counting circuit after a particular number of cycles, such closure generating a count pulse for a first counter. In the event that a second pulse series W1 occurs simultaneously with a series of pulses W2, this is detected by AND gates to cause a termination of the recycling W2 pulses and resetting of the counting circuit controlling this, whereby the second impurity causes the recycling process to begin once more, a pulse being provided to the first counter only by each impurity which does not occur within a horizontal distance represented by the time W 1 and a vertical distance represented by the time W2 on the scan of the surface in the direction of scan thereof. A second counter is provided to count the number of single pulses indicative of each impurity.

Abstract: 347,018. Valve detecting circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. May 7, 1930, No. 14063. Convention date, June 20, 1929. [Class 40 (v).] In a grid detector circuit, two or more grids, at least one of which has a grid condenser, are provided in the same detector valve and are connected to an equal number of points in the circuit whereby the working of the grids for anode detection is wholly or partly nullified. The output from the high frequency amplifier I is applied to the doublegrid detector II through a tuned circuit 7, the coil 9 being centre-tapped for the high tension feed so that for high frequency the two grids act in phase opposition while their average potentials are equal. By this means they mutually assist for grid detection and act in opposition for anode detection, thus eliminating distortion with large detector inputs. The valve II may have its grids in one plane, the members being interspaced. The two grids are shown provided with grid condensers 11, 12 and grid leaks 18, 19 although the provision of grid condensers for all the grids is not necessary. For valves having n grids, the latter should be connected to n points on the oscillatory circuit such that their phase displacement is 360‹. In Fig. 2 (not shown) the tuned circuit 7 is modified to eliminate hand capacity effects on the tuning condenser 8.

Title: Improvements in and relating to frictional control gearing
IPC: B64C11/34
Filed: 1937-05-26
Abstract: 496,274. Screw propellers. ANDERSON, R: M. J., and FLEET, C. May 26, 1937, No. 14559. [Class 114] [Also in Group XXIV] A frictional gear for transmitting or increasing the power exercised by fluid pressure or other controlling agency comprises an axially movable cage D fitted with inclined rollers C and arranged between an axially movable sleeve A having a double-conical surface and a cylindrical member which is fixed or rotatable but not axially movable. As shown in Fig. 3, for controlling a variable-pitch airscrew, the cylindrical member on which the cage D slides is the driving shaft S or a sleeve rigidly mounted thereon. The cage D is actuated by air pressure on a member p, the pressure being counterbalanced by a spring h interposed between the cage D and a shoulder in the fixed member a on which the hub b of the airscrew rotates. The blades d of the airscrew engage sockets c on the hub and have helical or like grooves e engaged by members g connected by a link l to a lever J actuated by the ring E of the double-conical sleeve A. Axial movement of the cage D causes one set of rollers C to be gripped between the sleeve A and the shaft S, so that the cage D is rotated and moves axially owing to the inclination of the rollers C. This axial movement is transmitted by the ring E, levers J &c. to the members g for adjusting the pitch of the blades. In a modification, Fig. 4, for adjusting the pitch of airscrew blades, the cage D is connected to a soft-iron ring y slidable on the shaft S within a circular permanent magnet r and a solenoid t mounted on the sleeve A. The solenoid is connected to the circuit of a generator driven from the shaft S, and variations in the speed of the shaft and generator cause variations in the field of the solenoid, resulting in axial movement of the ring y and cage D and corresponding adjustment of the airscrew blades.
