Abstract: 126,968. Bristow, C. May 14, 1918, [Convention date]. Powder blowers &c.-Grain, seeds, manures, powdered materials, &c., are discharged from a drill, broadcaster, &c., by a pneumatic device adapted to deliver a constant volume and provided with adjustable means for dividing the material as it issues into two parts, one of which is delivered to the distributing-appliances while the other is returned to the hopper. In the form shown in Fig. 2, the seed &c. passes from the hopper 1 into the intake 2 of a tapered and flared pipe 3 and is driven by compressed air against a plate 16 which directs part of it into the hopper 1 and part into a, spout 19 leading to a drill coulter, broadcaster, or the like. The compressed air is supplied through a flanged hole 7, a fixed or adjustable nozzle 5, and a pipe 6. The interior of the pipe 3 communicates with the atmosphere through openings in it or through a short pipe 9 provided with lips 10 and wire gauze endcoverings 11. The material in the hopper is agitated by a reciprocating tube 12 provided with branches 13. Air enters the tube through gauze end-coverings 15 and escapes through holes 14. Compressed air may be forced through the tube 12. The deflecting-plate 16 is curved and provided with a ridge 17, as shown. The quantity of seeds &c. delivered to the drill coulters &c. is regulated by adjusting the plates 16 by rocking the shaft 21 carrying a number of them. The shaft 21 is provided with an adjusting-handle, with means for locking it in position, and with a pointer and graduated scale for indicating the number of bushels sown per acre. In a modification, the plate 16 is moved by means of a rack and pinion.

Patent GB-699772-A (GB)
Title: Improvements in or relating to rust inhibiting compounds
IPC: C10L1/24
Filed: 1951-05-29
Abstract: The invention comprises an addition compound obtained by reacting together alphapinene and a petroleum sulphonic acid, preferably in equimolecular proportions.  In examples products obtainable by the action of petroleum sulphonic acids on a -pinene, when heating to reflux, give compositions with acid-treated coastal stock lubricating oils, which give considerable resistance to rusting of specimens of steel.  The petroleum sulphonic acids used are obtained by treating a lubricating oil fraction with fuming sulphuric acid, settling and extracting with isopropanol/water.ALSO:Oil compositions prepared by dissolving compounds obtained by the reaction of a -pinene and sulphonated petroleum fractions in 2 specimens of acid-treated Coastal lubricating oils give greatly increased rust-resistance to test specimens of cold rolled steel. The compounds generally may be added to any mineral oil, including naphthas, spindle oils, lubricating oil fractions and with other ingredients as in greases, sprays and paints, and with or without other additives, and to motor fuels, emulsions, hydrocarbon polymers and polishes.

Title: Variable attenuation device
IPC: G06V10/10
Filed: 1962-04-02
Abstract: 959,510. Automatic volume control. NATIONAL CASH REGISTER CO. April 2, 1962 [Aug. 18, 1961], No. 12580/62. Heading H4R. [Also in Division G1] A variable impedance device intended to be connected in an automatic volume control circuit comprises, Fig. 3, a pair of rectifiers 15 and 17 connected respectively in shunt and series with the signal path and supplied with a standing current from the voltage developed across a third diode 23. The impedances of the diodes are differentially adjusted by a control current i c  so that the transfer conductance presented by the circuit to the input signal i s  is varied, thus varying the level of the output signal i c . A biasing current I c  adjusts the operating point of the diodes so that they work over the required range of variation of transfer conductance. The characteristics of the circuit may be modified by inserting resistors in series with either of the diodes 15 or 17 and the initial bias developed across diode 23 adjusted by inserting a resistor in series with the diode (Fig. 5, not shown). The circuit may be connected at the input of an amplifier the control current being derived by peak rectifying the amplifier output signal. The peak rectifier circuit. Fig. 7, comprises two emitter followers, a PNP transistor 72 and an NPN transistor 74 producing voltages on their emitters corresponding respectively to the negative peak and the positive peak of the input voltage e 0 . The negative peak voltage is applied to one electrode of a capacitor 82 whilst the positive peak voltage is added to a reference potential appearing across a Zener diode 85 and applied to the other electrode of the capacitor 82. The potential across the capacitor then represents the difference between the peak to peak voltage of the input signal and the reference potential supplied by the Zener diode. This difference is amplified and provides a control current i c  at the collector of transistor 96.
