Patent GB-1034144-A (GB)
Title: Carburetors
IPC: F02M17/16
Filed: 1965-02-23
Abstract: <PICT:1034144/C4-C5/1> In a carburetter a rotatable hygroscopic element 13 is partly immersed in liquid fuel 24 and partly disposed in an air passage 10 so that the air-flow causes rotation by impinging on vanes 18. The end 19 has internal and external vanes 21, 20 to agitate the liquid fuel and deliver it through passage 23 to head 17, which is additionally saturated by capillary attraction. The air flow takes up fuel from head 17, and vanes 18 assist mixing by agitation.  The element 13, e.g. a porous ceramic, may be in flat disc, cylinder, cone or globe form.

Title: Improvements in or relating to electrical pulse generator circuit arrangements
IPC: H03K3/543
Filed: 1946-03-13
Abstract: 663,911. Pulse generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 13, 1946 [Dec. 28, 1944], No. 7890/46. Class 40 (vi). A low-frequency-wave, applied to the control grid of a normally non-conducting screen-grid valve causes a high-frequency tuned circuit in the anode lead to ring, only one large amplitude burst of high-frequency energy being produced during each cycle of the applied wave due to the large value of screen dropping resistor and small value of associated capacitor which discharges during the conducting period of the valve, Fig. 2 (not shown). The high-frequency damped wave train may be clipped to produce a pulse which in turn causes a higher frequency tuned circuit to ring, a narrower pulse being desired from the higher frequency wave-train. A sine wave 11 from oscillator 10 drives the valve 15 into grid current, thus establishing a negative bias on the grid sufficient to maintain the valve normally cut off. During the positive peaks, valve 15 conducts, causing the tuned circuit comprising inductor 19 and stray capacities 20 to ring and generate a damped wave train 21. Due to the high screen resistor 27 and small by-pass capacitor 29 the screen potential falls rapidly during the conducting period. The wave train is fed over coupling capacitor 33 to clipping amplifier 37 biased beyond cut-off by connecting the grid resistor 44 to a point on the grid resistor 16 of the previous valve. The short pulse of anode current in valve 37 may be used to shockexcite a further tuned circuit 38, 39 having a higher resonant frequency than circuits 19, 20. The first positive half-cycle may be applied to a further clipping amplifier to derive a short-pulse. The oscillator 10 may be replaced by a squarewave oscillator.

Abstract: 555,707. Feeding webs. WOOD NEWSPAPER MACHINERY CORPORATION. June 19, 1942, No. 8463. Convention date, July 22, 1941. [Class 100 (i)] To facilitate the web renewing operation in a printing press or other machine, the rolls are prepared with a coating of adhesive at the outer surface of the leading end of the web and also at the opposite side of the web near its core, the adhesive being of a kind which will not adhere to the uncoated web surface but will adhere strongly to a similar adhesive coating. In operation, the new roll is brought into contact with the running web so that it is rotated thereby but does not adhere thereto until the adhesive on the running web contacts with that on the new roll whereupon the end of the new roll, which was previously lightly attached to the body of the roll in the usual way, becomes attached to the old web which is afterwards broken or severed by a knife. The adhesive, which may be any suitable non-vulcanizing rubber cement, such as unvulcanized rubber in a suitable solvent is applied as a layer 16, Fig. 2, to the outer surface of the end 13 of the web 26 or to a separate web section adhered to the end of the web, and also as a layer 17 on the opposite side near the core end of the web, or, as shown, to a separate strip 19 adhered to the web 26. The layer 17 is at least as long as the circumference of the roll to ensure contact with the layer 16 of the contacting roll. To prevent possibility of adherence between the layer 17 and the adjacent layers of the web, a layer 23 of adhesive-repellent, such as wax may be applied to the web at the rear of the layer 17. A line of perforations may be provided at the rear of the layer 17 to facilitate breaking of the old web during the renewing operation.

Title: Control circuit for commutator motor
Filed: 1963-03-05
Abstract: 1, 022, 372. Automatic speed control. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. March 5,1963 [March 5, 1962], No. 8744/63. Heading G3R. The brush gear of a commutator motor is shifted by pilot motor PM controlled by a feedback loop circuit comprising reference potentiometer R1 and tachometer generator TM, the error voltage being limited by diodes U1, U2 associated with resistors R3, R4. The limited error voltage, applied to winding 1 of magnetic amplifier Y1, is integrated by servo motor M1 driving the slider of potentiometer R6. The flux produced by winding 1 is opposed by that produced by winding 2 which is connected to resistor R6, the resultant output voltage of the magnetic amplifier being limited by saturation. During the starting operation of the commutator motor, a constant voltage is applied to the auxiliary phase windings of the motors M1, PM, so that they operate at constant speed until the windings 1, 2, are balanced and the auxiliary motors are stopped. The brush gear is then in a position which corresponds to optimum acceleration of the commutator motor. When the error voltage becomes less than the limiting value determined by adjustment of resistor R3, the motor PM displaces the brush gear to restore the speed of the commutator motor to the desired value. A smooth changeover from the starting operation to the running operation of the commutator motor is afforded by differentiating capacitor C1, and resistor R2 connected to the output of the magnetic amplifier.
