Filed: 1917-06-23
Abstract: 116,763. Hey. H. June 23, 1917. Bleaching and washing, processes and materials for.-Raw wool is cleaned, carbonized, and sterilized by (1) steeping in a cold dilute solution of sulphuric acid, hydrochloric acid, or sulphuric acid and sodium chloride, to which a dilute solution of formaldehyde may be added, (2) draining, and drying by heating to 80‹ C., (3) extracting with a grease solvent, for example petrol or naphtha, and again drying, and (4) removing the friable vegetable and other insoluble foreign matter by crushing, opening, and beating in a current of air. If desired, the adhering acid and soluble salts are then washed away with water, and the combined acid is neutralized by a solution of alkali carbonate followed by washing in a dilute soap solution. Specifications 17437/04, 26843/06, and 24699/12 are referred to.

Title: Apparatus for controlling operations which depend upon the angular position of a rotating shaft
IPC: F02P5/15
Filed: 1970-02-25
Abstract: 1293246 Ignition systems; fluid logic and switching circuits ROBERT BOSCH GmbH 25 Feb 1970 [26 Feb 1969] 9055/70 Headings F1B and F1P [Also in Division G4] In a system for controlling the ignition or fuel injection of an internal combustion engine, a rotating shaft carries a disc 10 with markers 12 and teeth. A sensor 11 detects the passage of the markers 12 and the teeth. One marker triggers monostable circuit 19, whose relaxation time is controlled by various engine parameters causing gate 17 to open and allow counter 15 to connect pulses from oscillator 18 in the forward direction. The other markers 12 causes bi-stable circuit 21 to trigger and open gate 14. The pulses generated by the teeth on disc 10 are shaped by unit 13 and counted in the downward direction by counter 15. When counter 15 records zero an output pulse is produced which controls the ignition or fuel injection, and switches bi-stable 21 so that gate 14 is closed. In this way the timing of the control pulse is determined by both engine parameters and the speed of shaft rotation. The device may operate electronically or by means of fluid logic. In a second embodiment, the markers 12, the bi-stable 21 and gate 14 are dispersed with.

Title: Apparatus for coating articles of manufacture with bronze or other pulverulent colors
IPC: B41G1/00
Filed: 1922-03-29
Abstract: 199,498. Eckert, C. March 29, 1922. Bronzing and the like; drying-apparatus.-In bronzing &c. apparatus of the kind in which bronze or other coloured powder is delivered on to rotating blades which scatter it on to the material to be coated, the blades 8 consist of screens of wire gauze or textile fabric whereby a fine distribution of the bronze is effected: The bronze is contained in a hopper 11 and is delivered on to the blades 8 by means of a rotating roller 12 in the, bottom of the hopper. The apparatus is adapted for coating articles such as sheets or webs of paper or parchment paper, sheets of tinfoil, glass plates and beading and frames for pictures. In one form for coating a web of paper, the web passes round a roller mounted in a trough containing an adhesive, such as a weak resin or wax solution or flour or other paste, and then passes through a bronzing casing 6 and finally through a gas-heated drying chamber, the level of the adhesive being such that only the underside of the web is coated. Sheets of paper 10 hanging loosely from the sides of the casing prevent adherence of the powder to the sides, V-shaped ledges 9 being provided behind the sheets to direct any powder passing behind to receptacles outside the casing. The web 4 to be coated is guided between endless bands 15, 16 which engage it at the edges only and, after passing through the casing 6, is led in an oblique or vertical direction past beaters 32 pivoted at 34 and operated by projections on a sprocket 31 which drives the roller 12 through a chain 30. Loose powder is thus removed and falls into a drawer 36. Any remaining loose powder is removed by a suction tube 26 after which the web is subjected to rubbing rollers 25. A drawer 35 for loose powder is also provided in the casing 6. When glass plates are coated the leaf formed may be stripped off for separate use.

Abstract: 216,108. Western Electric Co., Ltd., (Assignees of Espenschied, L.). May 15, 1923, [Convention date]. Thermionic heterodyne receivers; compounding frequencies by modulation. - Oscillatory currents, such as those used in wireless reception and transmission, are passed successively through the same amplifier a number of times, the frequency being changed after each stage of amplification. The frequency - changing means preferably comprises interaction with locally-produced energy by heterodyning, and rectification. Incoming modulated oscillations in the circuit ML pass through a filter F1 to the input circuit 20 of the amplifier A, and the amplified output passes from circuit 21 through filter F1<1 >to a modulator M1 which is also supplied with local oscillations so as to produce a supersonic difference frequency. This passes through circuit 22 and through a filter F2 and is again applied to the input) circuit 20 of the valve A. The output of the difference frequency is selected by filter F2' and passes to a detector M2, the resulting voice or signal current passing through circuit 23 and filter F3 to the input circuit of the valve A. The amplified voice currents are selected by the filter F3' and pass to the line L. Filters F1, F1<1> are designed to pass the carrier frequency and its side bands, filters F2, F2' to pass the intermediate frequency and its side bands, and filters F3, F3' to pass the voice or other signal currents. Further frequency-changing stages may be provided. The input and output transformers of the valve A may each comprise several transformers, designed respectively for the frequency range they are to transmit. The invention may be employed in a wireless transmitter for stepping up a lower frequency to a radio frequency by a plurality of steps of modulation.

Abstract: 596,670. Calculating-apparatus. TAYLOR, S. M., and BUGLER, F. E. W. April 18, 1945, No. 9762. [Class 106 (i)] [Also in Group XL] In a circuit for counting recurrent pulses, a counting circuit is arranged to be started by a first signal pulse and stopped by a second, means being provided for inhibiting stopping the counting sequence and means responsive to a condition or coincidence in the counting circuit for removing the inhibition to prepare the circuit for being stopped by the next signal pulse. The invention is described as applied to the circuit described in Specification 584,422 in which a train of pulses is applied to the trigger device 1, operating as a scale-of-two counter, the output being fed through a gating amplifier valve 7 to further trigger devices 4, 5. The output pulse from the device 5 is arranged to reverse a trigger pair in the stage 6 which causes the next pulse (corresponding to the tenth input pulse) from device 1 to pass through amplifier 8 to the output, thus giving a scale of ten count. Leads from the anode of the right hand valve in each trigger pair are taken to a selector switch 13, the connections being such that for any given setting of the switch, the state of the valves during the time up to the receipt of the selected pulse, causes one or more of the diodes 9 to be conducting. When the selected pulse is received, the trigger pair (or pairs) reverses, the anode potential falling and causing the diode (or diodes) to cease conducting and the cathode potential to fall rapidly. Starting or stopping circuit. The train of pulses, fed to the grid of valve 22 are not amplified due to the paralysing bias on the valve. A negative starting pulse, applied to the grid of conducting valve 27 cuts it off and due to the multivibrator connection valve 28 is rendered conducting. The rise in anode potential of valve 27 raises the grid potential of valve 22, the pulse train passing through to the counting circuit. The stopping circuit is normally shorted over the contacts of a relay but upon the selected pulse passing into the counter, the potential across resistance 12 falls sharply and due to the connection to the cathode of biassed diode 45, the diode conducts feeding a negative pulse to valve 50, the output pulse firing thyratron 42 to operate the relay and remove the short circuit. The stopping signal is now effective, and passes through valve 35 to fire thyratron 36, the negative output pulse resetting the trigger pair 28, 27 thereby paralysing valve 22.
