Abstract: 791,455. Dispensing measured quantities of lubricant. SATZGER, E. July 11, 1955 [July 24, 1954], No. 20007/55. Class 12 (3). A dispenser for lubricants, which is adapted to be connected to an inlet conduit 2 arranged to be temporarily pressurized comprises a reservoir 5 for receiving the quantity of lubricant to be dispensed and is characterized. by a member 7 of resiliently deformable material, such as rubber or the like, which tightly encloses the mouth of the inlet conduit 4 and when deformed under the pressure in the conduit is applied against the inside wall of the reservoir to act as a piston. The piston is moved upwardly by the pressure against the action of return spring 10 and forces the lubricant through an outlet conduit 3<SP>11</SP> which is eventually closed by a metal part 8<SP>1</SP>. When the pressure drops in the conduit 2 the member 7 is returned to its position of rest by the spring 10 and simultaneously contracts. The conduit 4 may be longitudinally adjustable to enable the quantity of lubricant dispensed to be varied. Alternatively, an adjustable screw may be mounted within the conduit. The spring 10 may be mounted exteriorly of the member 7 which is then formed with a boss on its upper face to locate one end of the spring, the other end of the spring being located by a boss at the upper end of the casing 1 of the dispenser.

Abstract: 1,015,886. Character recognition. FERRANTI Ltd. May 22, 1964 [May 24, 1963], No. 20727/63. Heading G4R. A character is scanned in two angularlyspaced directions by lines of light 13 (Fig. 2) moving in the direction 14 from cathode-ray tubes 11 or 111 (Fig. 1) and the resultant waveform produced by a photo-cell 15 is modified by removal of the D.C. component by a capacitor 17 and addition of a fixed D.C. by a restorer 21 and the modified signal is applied to a delay line 25 for comparison with a standard signal with mean amplitude determined by an integrator 23 from a pulse generator 27 applied through a selector switch 31 to one of coils 26 on the delay line 25 such that coincidence of signals at 34 gives a signal at 37 if they are the same. The modified signal is applied to an amplitude discriminator which produces a time pulse just outlasting the scan period to activate the pulse generator 27 at the end of a pulse and also a comparator 36 which compares the root-mean-square of the summated signals at 34 and the integrated signal from 23. Signals on lines 37 and 137 (Fig. 4) from the two directions of scanning indicate an identity through an " and " gate 40 connected to a rotary switch 41 moving in synchronism with switch 31. An equality signal on only one line 37, 137 gives a warning output on line 46. The coils 26 are wound one on top of each other or side-byside with a delay in the pulse circuit inverse to its distance from the pick-up 34 or on a number of equal length branch lines from the central delay line 25. Instead of equalizing the mean amplitude of the standard signals, the integrated signal is applied as a gain-control to a variable gain stage following the D.C. restoration stage 21 such that the modified signal is given a constant predetermined mean amplitude and the second input to the comparator 36 may be supplied from a fixed potential source. The standard waveform may be produced on an amplitude sampling basis in which pulses are applied simultaneously to identical coils set up along the delay line 25 and connected through a matrix of resistors arranged to produce currents with amplitude corresponding to the standard character.
