Patent GB-1298953-A (GB)
Title: An improved method and apparatus for automatically inspecting the surface of a woven fabric
IPC: D06H1/00
Filed: 1969-12-09
Abstract: 1298953 Detecting fabric defects photoelectrically ENSHU Ltd 9 Dec 1969 [10 Dec  1968] 60090/69 Heading G1A Defects in fabric 14 coming off a loom are detected by a light source/photo-detector arrangement 18-19 and the cumulative defect total is indicated by the position of a marker 36 on a dial 3 which also indicates by means of a marker 34 the amount of fabric passing over the roller 16. The marker 34 displays the output of a photodetector 31 separated from a light source 29 by a rotating apertured disc 26. Each rotation by the marker 34 of an angle # - see Fig. 3 - corresponds to a complete length of finished fabric, so when marker 34 contacts the fixed abutment 37, a signal is produced which actuates a device for making a cut mark on the fabric. The marker 36 also rotates anti-clockwise, and at the beginning of each cycle is automatically reset to be an angle # 2  behind marker 34. This angle # 2  represents the greatest permissible defect count per unit length for A-grade fabric, and if marker 36 contacts marker 34 during a revolution, this gives a visual indication that the corresponding fabric piece is not A-grade. The output of the photo-cell 19 is also supplied to a comparator device, 6, Fig. 1 (not shown) which also receives an input from a reference information source (7) which indicates the maximum number of defects and rate of defect formation that are allowable. If either of these is exceeded the loom is stopped and an alarm lamp is actuated. The defect signals from the photo-cell are also supplied to a recorder (9). The elongated source 18 may be replaced by a scanning source.

Title: Improvements in or relating to the manufacture of mouthpiece cigarettes
IPC: A24C5/343
Filed: 1958-01-07
Abstract: 842,021. Testing mouthpiece cigarettes. MOLINS, D. W., and MOLINS MACHINE CO. Ltd. Jan. 7, 1958 [Jan. 8, 1957], No. 726/57. Class 130. Defective adhesion, between gummed encircling bands 4, Fig. 2, and the elements of doublelength cigarette-mouthpiece assemblies 2, 3 in flutes of a drum on which they are severed by a disc knife 6, is detected by sponge rubber rollers 7, or sets of rubber discs, which urge the cigarette portions 2 apart towards stops 9, the mouthpiece portions 3 being retained by the knife 6 or, if the rollers 7 act'before or after cutting, by pressure guides 8.

Patent GB-769392-A (GB)
IPC: G06C23/02
Abstract: 769,392. Calculating apparatus. NATIONAL CASH REGISTER CO. May 23, 1955, (July 29, 1954; Nov. 15, 1954], No. 14804/55. Class 106 (1). Ina full-keyboard power-operated calculating machine having amount keys, which are partially depressible to control the differential mechanisms and any one of which may be fully depressed to initiate a cycle of operation, the normal release of the depressed keys at the end of a cycle is prevented when an amount key is maintained in fully depressed position. The invention is embodied in a machine having cycleinitiating means as described in Specification 710,318, and comprising, for each order of keys, a bar 14 which, on full depression of a key, is cammed forwardly to rock a bail which allows a switch in the circuit of an electromagnet to close. The electromagnet actuates the normal machinerelease trip mechanism. The depressed keys are normally released by rocking of a bail 43 having for each order; two fingers 45 which disengage a detent bar 17 and a zero stop control bar 46 from notches in the key stems. In one embodiment of the present invention, the slots 49 in the key-release bail for the bars 14 are reduced in length or partially blocked by a plate 48 so that, if a key is held depressed, the corresponding bar 14 will hold the key-release bail 43 against movement. To permit such blocking of the bail, it is operated through a resilient coupling, Fig. 1 (not shown), including a compression spring. In a different embodiment, each order of keys is locked throughout most of the cycle by a corresponding shutter 64, Fig. 7. The shutters 64 are rocked to locking position, in which they engage above or below projections on the key stems, by a slide 61 moved to the left, Fig. 7, against the action of a spring by a cam lever 74, 71 (see also Fig. 6) which engages a roller 70 in the machine trip lever 60. The slide 61 is held in operative position, however, until after the trip lever 60 is restored, by an arm 80 which follows the keyrelease lever 29 and enters a slot 68 in the slide 61. If a key is held fully depressed, the trip lever 60 will be only momentarily released and a further cycle will follow. The amount keys will remain depressed during operation of the bail 43 by the lever 29, due to the shutters 64 which are held effective during the momentary release of the trip lever 60 by the arm 80. The trip lever 60 is also actuated, in known manner, by add and subtract, keys and if one of these is held depressed, the shutters 64 will again be held in effective positions and a repeat cycle will ensue.

Title: Rotary liquid atomizer
IPC: B05B3/10
Filed: 1978-11-20
Abstract: A rotary liquid atomizer comprises a drive shaft (3) carrying for rotation therewith a rotary member (1) e.g. circular tray-like or saucer-like in shape, having a symmetrical upper liquid guide surface (11) and a peripheral annular rim (8) of which the inner wall inclines gradually radially outwards and upwards from the guide surface (11) terminating in a top wall (12) orientated perpendicular to the rotational axis. A large number of shallow grooves (13) are located around the rim (8) at substantially uniform small circumferential pitch, each extending between the periphery of the guide surface (11) and the top wall (12) in the direction of flow of liquid supplied to a central portion (6) of the rotary member (1) and caused to flow outwardly over the guide surface (11) by centrifugal force on rotation of the rotary member (1). Thus liquid flows outwardly through the grooves (13) in fine streams of substantially uniform diameter and issues therefrom at the top wall (12) as finely atomized substantially uniform droplets. <IMAGE>

Title: Fuel control for a gas turbine engine reheat system
IPC: F02C9/26
Filed: 1979-01-15
Abstract: A gas turbine engine reheat fuel control system has metering valves 16, 17, 18 which control fuel flow from a pump 14 to respective reheat burners 11, 12, 13 on the engine 10. The flow areas of valves 16, 17, 18 are controlled by electrical signals on lines 48, 68, 69 from a circuit 20. The pump 14 has a throttle valve (not shown) comprised of an axially movable sleeve in the inlet duct which is moved in response to a signal on a line 31 from the circuit 20. The signal on line 31 is primarily responsive to the sum of the fuel flows through the valves 16, 17, 18 as determined by the flow areas of the valves and pressure differentials across them. The signal on line 31 is modified in accordance with the pressure differential across one of the valves, so that the fuel delivered by the pump is increased until this pressure differential corresponds to a calculated value based on the required reheat fuel flow. <IMAGE>

Patent GB-2029985-A (GB)
Title: Electrical control circuits
IPC: G05B21/02
Filed: 1979-07-24
Abstract: An electrical control circuit comprising A-D, D-A conversion and a summing junction. Basically, an analog signal from some source is fed to a unity gain summing amplifier by means of two parallel paths, with one path containing an inverting means. Initially, the signals from the two paths which enter the summing junction sum to zero, but after operation of a "hold" circuit 52 such signals sum to a value that may be used for logic purposes. In one embodiment the analogue signal represents a welding current. The "hold" is operated at the time of work clamping; the welding current increases and the output of the summer is compared with a reference to terminate welding when they are equal. In a rolling mill, the analogue signal 50 represents roll force, changes in which adjust the roll gap to compensate for mill spring by the servo loop shown, in which the output of the summer is compared with a roll position signal. <IMAGE>
