Title: Improved means for grinding or polishing file, cutlery and other blanks
IPC: B24B19/00
Filed: 1922-07-31
Abstract: 206,218. Moore, F. July 31, 1922. Files and file blanks, treating; cutting-edges, shaping and treating.-A machine for grinding and polishing file, cutlery, and other blanks comprises a circular worktable 1 rotatably supported on slides or rollers on a standard 2 which also supports the spindle of a grinding-wheel 3. On the grinding-wheel spindle is a bush 6<a> carrying a loose pulley 6 and a fast pulley 5 which rotates the table through gearing 7, 8, 9. The blanks are supported, singly or in sets, by holders 11 adjustable on slides 13 adjust ably carried by vertical spindles 14 slidable vertically in bearings 14b in the table, a series of slides being arranged around the table. The bearings 14<b> have caps 14<a> or loather or rubber covers or felt rings to protect them against swarf or water. The spindles carry rollers 15 bearing on a cam 16 clamped to a disc 18, which is supported by a pendant pin 17 hung from the table; each holder is associated with a pin 17 and cam 16, the form of the various cams being the same or different according to the form required for each set of blanks. On the disc 18 is an arm 19, the radial position of which can be adjusted, the arm engaging once in each revolution of the table, when the blanks are passing beneath the grinding-wheel, with a fixed tappetpin 20. The consequent rotation of the cam 16 causes the spindles 14 to rise or fall, and thus give the required form to the blanks; on release ot the arm 19 from the pin 20 a spring 21 returns the arm to the normal position. Beneath the arm 19 is a disc 22 having two projections resting on a feed cam 23, which is clamped to a sleeve 24 carried on the pin 17, and fixed to the sleeve are detachable projecting arms 25. As the table rotates the arms engage a bracket 26 on the standard 2, causing partial rotation of the feedcam and a corresponding upward feed of the blanks; the arrangement may be such that after five revolutions of the table, and five feeds, the blanks are finished, the cam being shaped to allow the blanks then to fall clear of the grinding- wheel, and a short arm 25 being presented to the bracket 26, no action takes place. When a quicker feed is required, a second set of arms, operating similarly with a bracket 27, may be provided on the sleeve 24. The relative positions of the disc 22 and cam 23 may be reversed. To compensate for wear of the grinding-wheel, a hand-wheel 28 screws on the pin 17 to lift the cam gears. Water or other cooling medium is supplied by a pipe and runs away to the inside of the standard through holes 39, 40. In operation, as the table rotates, the sets of blanks come successively beneath the grinding-wheel. When complete]y ground the blanks are turned over to present unground faces, or replaced by other blanks. The holders may be detachable; the grinding-wheel may be on a separate standard. The table may have a to and fro rotating or semirotating movement or may have intermittent rotation.

A flow of liquid is continuously tested for contamination by apparatus comprising a conduit 12, along which the liquid flows, a light source 38, having its light rays restricted to a predetermined path transversely across the conduit, by an aperture 54, a photo-cell 56 facing the light source and having its cone of visibility A limited by a cylinder 64, and a shield 60 preventing light from the source 38 from directly reaching the photocell 56, the photo-cell thus being energized only by scattered light caused by contamination particles in the liquid such that its output represents the contamination of the liquid. The shield 60 is provided with an aperture 127 normally blocked by the end of a rod 80, the rod however is provided with an aperture 128 which can be brought into alignment with aperture 127 on depression of spring loaded knob 82, such as to allow light from the source 38 to directly impinge on the photo-cell 56, causing a rapid increase in its output. This can be used to test whether the apparatus is working and for calibration purposes. The apparatus may be used, Fig. 3 (not shown), to test the purity of filtered petrol in a petrol delivery pump and may be calibrated for zero contamination by passing fully filtered petrol through the apparatus. The output of the photo-cell may be used to actuate a meter, a recorder or operate warning lights.

Title: Nonlinear amplifier
IPC: H04N5/202
Filed: 1960-06-20
Abstract: 951,413. Electric analogue computors. FERNSEH G. m.b. H. June 20, 1960 [June 20, 1959], No. 21532/60. Heading G4G [Also in Division H4] In a non-linear gamma correction circuit for television signals in which the minimum black level differs appreciably from the blanking level the mimimum black level in the signal is maintained at a substantially constant position on the nonlinear amplifier characteristic. Positively poled signals are applied to a nonlinear amplifier comprising a cathode follower 3, the cathode load of which comprises resistors 5-8 in series, the output being taken across resistor 8 and the junction points of the resistors being shunted to earth over diodes 9-11 which in conjunction with series resistors 13-15 give the desired non-linear characteristic. The input is applied over blocking condenser 2, the D.C. level at the grid of the valve 3 being determined by a clamp circuit 18, 19, 20 driven by pulses applied at terminals 21, 22 to be conductive during the blanking period. From the cathode of valve 3 the picture signal passes by capacitor 24 to diodes 27, 28 which are cut off during the blanking intervals by negative-going pulses applied to their anodes over condenser 39. The clamp circuit is returned to an adjustable negative potential derived from point 30 in a potentiometer 31-34. The circuit clamps the wave form at the cathode of the diode 28 so that the minimum black level is at the potential of the point 30. The blanking pulses in this waveform are negative going and are passed to condenser 36 by a gate circuit comprising diodes 25, 26 driven conductive during the blanking interval by positivegoing pulses applied to their anodes via condenser 37. The negative potential developed across condenser 36 is proportional to the distance between the blanking level and the minimum signal black level and is applied as a clamping potential to the grid of the valve 3 via the clamp circuit 18,19, 20. Switch 23 enables a fixed clamping potential from point 30 to be substituted.
