Title: Stored image control system
IPC: H01J37/302
Filed: 1965-02-05
Abstract: 1,068,482. Welding by fusion. UNITED AIRCRAFT CORPORATION. Feb. 5, 1965 [March 2, 1964], No. 5140/65. Heading B3R. [Also in Division G3] An image of an article to be worked by an energized beam is projected, scanned and then stored until the article is located in its working position when the energized beam is controlled to perform work on the article in response to the scanning of the stored image. As shown, an electron beam machine 10 comprises an evacuated chamber 12, containing cathode 14, Wehnelt cylinder control electrode 22, anode 16 and magnetic lens 18 and deflection coils 20. Access to the chamber 12 is obtained by air locks 44, 48. Electronic components forming a workpiece to be welded are manually assembled on a substrate mounted on a movable table 24 and the positions of the welds indicated by a fluorescent dye. The table 24 is then accurately positioned under a rotating prism 30 to actuate a series of Record switches 26 causing the energization of an ultra-violet lamp 28. A logic circuit 40, detailed in Fig. 2, (not shown), is conditioned by the record switches 26 and prism control switches 46 to position the prism 30 in position A and project an image of the fluorescing dye marks on to the photo cathode of a camera tube 36. The deflection coils 38 of tube 36 are energized, through logic circuit 40, in synchronism with the deflection coils 43 of a storage tube 42 which is modulated in dependence on the signal from the tube 36 to store the image of the workpiece. The table 24 is then automatically moved through the airlock 44 and positioned to actuate the prism control switches 46. The prism then rotates to position B so that an image of the pattern on the storage tube 42 is projected on to the camera tube 36. The logic circuit 40 is conditioned to synchronize the deflection coils 20, 38 and the voltage on the control electrode 22 is gated by the output of the camera tube 36 when an image of a dye-mark is scanned to effect a weld. After the desired work has been performed the table 24 is removed from the chamber 12 through the air-lock 48. It is stated that a dual storage/readout system, duplicating that shown can be utilized so that there is always a workpiece, waiting to enter the air lock 44 or being pumped down in the air lock. It is also stated that the scanning system can be employed to control the beam from a solid or gaseous laser, deflection and gating of the laser output being effected by rotating mirrors or ultrasonic cells.

Title: Improvements in and relating to rotary malting drums
Inventor: RYMER JESSE TALBOT
IPC: C12C1/033
Filed: 1961-02-11
Abstract: A rotary malting drum comprises a cylindrical metal casing 10, Fig. 1, and inner and outer foraminous tubes 18 and 19 which with the end walls of the drum form the grain receptacle.  The drum rests on two rows of roller assemblies arranged to restrain lateral movement of the drum.  Between the outer tube and the casing is a complete annular series of triangular cross-section air ducts 20 which open at each end through ports 21 (Fig. 4) in the end wall of the drum, into an air chamber 22 defined by end cap 23 secured to the casing and making a sliding face seal 24 with the end of fixed air inlet conduit 25.  Communicating with the inner foraminous tube and extending through conduit 25 and air chamber 22 is a concentric air outlet conduit 26.  Seal 27 prevents air leakage from air inlet to air outlet conduit.  The air outlet conduit connecting with collecting duct 28 inside the end cap 23 has an arcuate aperture 29 located in the upper part of the drum lying adjacent a ring of ports 21 in the end of the drum, having at its edges two sealing members 30 bearing against the end wall of the drum.  The vertical plane at the end walls is divided into an air inlet zone and an air outlet zone with which each port registers alternately.  The zones are separated by circumferentially extending cheeks 31 (Fig. 4) on the collecting duct which prevent air blown into <PICT:0957617/C3/1> <PICT:0957617/C3/2> <PICT:0957617/C3/3> the chamber from escaping to the collecting duct without passing through the grain.  The cheeks are provided with valves to control the number of ports exposed to the air inlet which can be adjusted while the drum is rotating. For this purpose sealing members 30 extend circumferentially beyond the collecting duct to form two guides 34, Fig. 7, between which slides an arcuate baffle plate 35 bearing against seal plate 30 which is backed by arcuate slotted spacing plate 36 and cover 37 which carries a pinion box. The pinion 40 engages arcuate rack 39 on the back of the baffle plate, the rack being accommodated in a slot of the spacing plate. The pinion is connected to a handle by a system of shafts and a bevel gearing so that by rotation of the handle the baffle plate can be extended from or retracted into the cheek.  The drum which may be driven by friction rollers or by a pinion meshing with a gear wheel on the casing, is provided with loading and unloading and inspection doors.  In operation air is blown into the air chambers at each end and passes through air ducts 20 whose ports for the time being are exposed below the cheeks of the collecting duct and reaches the grain 32 by penetrating the outer foraminous tube. The air is exhausted partly through the inner foraminous tube and partly through the collecting duct.

Abstract: 622,210. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 19, 1946, No. 5202. Convention date, Dec. 31, 1941. [Class 40 (iii)] In a television transmitting system means are provided for producing a composite waveform of picture, blanking and synchronizing signals. Two multi-vibrator circuits including double-triode valves 18, 68, locked respectively to horizontal and vertical synchronizing pulses applied at terminals 12, 14 produce horizontal and vertical blanking pulses 65, 138 and horizontal and vertical deflection voltage waveforms 64, 142, in addition to sawtooth voltage waveforms 66, 148, suitable for the deflection of a monitoring oscilloscope or for controlling shading signal generating apparatus. The vertical blanking pulse 138 comprises the addition of the output of the anode 76 of valve 68 (curve 134), after delay in network 124, 128, 126, 130, and the output of valve 110, the grid of which is also driven by vertical synchronizing signals. The locking signals applied to grid 72 of valve 68 are delayed by a predetermined amount in the R.C. network 86, 90, whilst those applied to the grid of valve 110 are not so delayed. The horizontal and vertical blanking pulses, extending in the positive direction, are applied to the grids 158, 160 of valve 154, the output of which, extending in the negative direction, is applied to the screen grid of valve 150 to the control grid of which is applied video signals derived from any suitable type of television transmitting tube, e.g. Iconoscope. Vertical synchronizing signals are applied to the control grid and horizontal synchronizing signals to the suppressor grid of valve 152 which is connected in parallel with valve 150. The horizontal synchronizing signals comprise the horizontal blanking pulses derived from valve 154 after differentiation by the R.C. network 210, 212. Both vertical and horizontal synchronizing signals are applied in the negative direction to valve 152. The level of the blanking pulses may be controlled by varying the voltage on the screen grid of valve 150 by means of potentiometer 190 and that of the synchronizing signals by varying the voltage on the screen grid of valve 152 by means of potentiometer 218. The output waveform of the system, which appears at terminals 236, comprises picture signals together with blanking and synchronizing signals, the latter signals extending into the " blaoker-than-black " region and occurring simultaneously with the front edge of the blanking signals. After amplification, this waveform may be used for amplitude or frequency modulation of a radio-frequency carrier wave.

Abstract: 124,584. Falconer, W. W. P. March 28, 1918. Clinometers. - Gravityactuated clinometers are described in connexion with the measurement of the flexing of the human joints, for which purpose they are adapted to be worn upon a limb. In the form shown in Figs. 1 and 2, a spindle b mounted in a casing a carries at the front end a fixed pointer f. A flanged dial c is mounted loosely at this end of the spindle and is graduated in degrees. It is clamped to the casing by a setscrew e which admits of adjusting the zero. The pointer f is held vertically by a weighted arm g attached either pivotally or otherwise to the spindle b. The casing is furnished with a strap for securing to a limb, and as the limb is flexed about its joint the dial moves with the limb, and the reading of the pointer affords an index of the extent of the movement. A double pointer l friction-tight on the spindle may be pushed around by engagement of the pointer f with a pin m to mark the reading on the dial. The pointer l is double to admit of movement to right or left, the one in use being first alined with the pointer f. Other forms are described for use with fingers in which a weighted graduated cylinder or quadrant is used, and supported on the finger by a spring clip. Liquid may be used inside an instrument with a graduated glass cover, or a weighted pendulum may rotate through gear wheels a dial inside a casing, the reading being viewed through a hole in the case.
