Filed: 1972-01-17
Abstract: 1376235 Measuring speed of an I C engine electrically ROBERT BOSCH GmbH 17 Jan 1972 [15 Jan 1971 (2)] 2059/72 Heading G1N Apparatus for monitoring the speed of an I.C. engine comprises means for producing a train of constant voltage pulses initiated by the ignition pulses, which are used to charge a capacitor to a voltage representing the engine speed, which voltage operates an alarm if the speed exceeds a predetermined value. The engine ignition system comprises a battery 37 Fig. 1 charging a capacitor 44. As shown for a 4-cylinder engine, a contact breaker 63 is opened four times per engine revolution, each opening causing a thyristor 58 to conduct, thereby discharging capacitor 44 through the primary winding 49 of the ignition coil 50, the corresponding high voltage pulse in the secondary winding 52 being fed by the rotor arm 53 sequentially to the spark-plugs 54-57. Each discharge pulse from capacitor 44 is also fed from terminal 66" or 66' via lead 17 to charge a capacitor 13 in the monitoring circuit 12 to a voltage determined by Zener diode 22 and discharging resistor 14. The average voltage across capacitor 13, determined by integrating unit 23, represents the angular speed of the engine. If this voltage exceeds a predetermined value set by resistors 29, 31 a thyristor 26 fires and energizes a buzzer 38. A negative temperature coefficient resistor 30 compensates for temperature variations. The thyristor 26 may be replaced by a Schmitt trigger circuit.

Title: Improved mechanism for operating electrical contacts and other devices
IPC: H01H43/00
Filed: 1927-01-27
Abstract: 289,527. Moy, Ltd., E. F., and Newman, A. S. Jan. 27, 1927. Switches, actuating; latching. - A switch, group of switches, or other device requiring considerable pressure for actuation is operated by means of a small initial effort by causing the initial effort (that, for example, derived from air pressure) to propel a small ball o into a position where it is carried round by a continuously-rotating disc or drum r and in so doing swings out a pivoted lever t and thereby brings contacts k, i into engagement. The ball continues its travel and, guided by the spring v and the shaped plate 9 is finally restored to its original position opposite its blow hole l. The lever t in swinging outwards is retained by a spring catch x. Where a number of switches, as described, are used in line (as for example for controlling electric lamps in the printing of kinematograph film), each switch is operated when its corresponding ball is propelled by air pressure admitted to the corresponding tube by means of apertures in a moving band. When one switch has been closed, as described, it remains closed until the next ball is put in action, whereupon the act of closing the second switch causes the tail-piece w to lift the common latch x and release the switch first closed.

Filed: 1934-01-26
Abstract: 416,255. Screw propellers. HAMILTON STANDARD PROPELLER CO., 400, South Main Street, East Hartford, Connecticut, U.S.A.-(Assignees of Caldwell, F. W.) Jan. 26, 1934, No. 2748. Convention date, Feb. 13, 1933. [Class 114.] A variable-pitch screw propeller has its blades connected by arms with centrifugally acting weights which are in turn connected by a pin and slot gear with a cylinder controlled by fluid pressure in a direction in opposition to the weights. A flanged counterweight bracket 40 is provided with forty equally spaced semi-circular notches and fits over a flange 21 on the blade root with thirty-six equally spaced notches, four of the notches matching so that a pin 42 may be inserted in each. The bracket 40 may thus be given 1‹ settings with respect to the blade and the pins are retained in place by a shim 41 on the boss 12. The bracket is extended at 48 to form a housing for the counterweight 50 to which is screwed a cap 52. The weights are disposed so as to tend to turn the blades into high pitch positions about the spigot arms 18, the turning moment being greater than the moment of the centrifugal force of the blades tending to set the blades into low pitch. To bring the blades to low pitch against the action of the counterweights, a cylinder 76 carries a pin 92 which engages a slot 100 in the support 48 so that as it is moved it moves the arm 48 and so the blade into low pitch position. An oil pump 56 driven by the engine, has a valve 62 whereby oil may be delivered to the hollow crankshaft and hollow piston 74 over which the cylinder 76 is slidable. The hollow piston is screwed at 80 to the crankshaft. Adjustable nuts 110, 112 in the counterweight limit the movement of the pin 92 in the slot 100 and determine the maximum and minimum pitch settings. The slot 100 is curved so that the net resultant moment available to turn the blade is substantially constant. The hub is provided with a laminated ring 124 formed of a phenolic-condensation product which serves as a chafing strip for the barrel 34. Specification 399,205 is referred to.

Title: Improvements in or relating to the ornamentation of fabrics, leather and the like
IPC: D06Q1/00
Filed: 1925-01-30
Abstract: 247,001. Vredenburg, J. C. Jan. 30, 1925. Ornamenting fabrics.-Fabrics, leather, and the like are ornamented by the application in spaced relation or in pattern effect of drops or globules of a substance consisting of the intermediate product of the reaction between a urea or its derivatives and aldehydes, particularly formaldehyde, the substance being applied in a liquid or plastic condition and allowed to harden into the final product. The ornamenting substance may be applied to the fabric by pushing needlelike devices therethrough from above and dipping the points into a receptacle containing the substance in a liquid or semi-liquid condition, so that on withdrawing the needles most of the liquid adhering thereto is stripped off and remains as a bead-like globule on the underside of the fabric. A small amount of the liquid substance will pass through to the upper surface of the fabric, and will spread or flatten under gravity, so that on hardening it serves as a flat securing head connected to the bead by the neck which fills the hole in the fabric. The fabric is maintained in a substantially horizontal condition during the hardening of the ornamenting substance, which may be facilitated by heating. The hardened substance, which is normally transparent and colourless, may be tinted as desired.
