Abstract: 983, 680. Sensing record cards. SPERRY RAND CORPORATION. July 16, 1963 [July 27, 1962], No. 28151/63. Heading G4M. The signal-to-noise ratio of a perforated-record reader is improved by choosing the distance between photo-cell 38 and record 20 so that only a small fraction of the light scattered through a non-perforated part of the record falls on cell 38. The signal-to-noise ratio is also improved by having cell 38 and light source 10 on opposite sides of the sensing position identified by line 54, Fig. 1. Light focused by lens 42, and passing through a perforation in record 20, all falls on cell 38, but the maximum intensity of light scattered through a non-perforated region is in the direction indicated by arrow 28, and does not fall on cell 38. The apparatus comprises a linear incandescent filament light source 10, Fig. 4 in a cylindrical housing 70 having an opening in which lens 42 is fixed. The record 20 passes over a glass plate 76 the underside of which is covered by an opaque metallic coating 78 except for a series of apertures 80 corresponding to index positions on the record. Each photo-cell 38 is mounted on a common terminal bar 88 and receives light through an individual bore 86 in an opaque insulating bar 84.

Title: Improvements in selective protecting systems for electrical networks
IPC: H02H1/00
Filed: 1939-10-23
Abstract: 533,322. Protective cut-out systems. HECHT, U., and ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 23, 1939, No. 28468. [Class 38 (v)] In a selective protective system of the kind in which release of the different section switches is controlled by auxiliary or pilot currents transmitted between the section-ends, release of the section switches is dependent on two pilot currents, release being prevented if one of them disappears. Preferably the currents comprise a fundamental-frequency current modulated with one or more other frequencies, a relay being provided which opens the trip circuit if either the fundamental or the modulation disappears. The trip circuit at each section-end A, B includes the contact 3' of a directional relay (not shown), contact 2<1> of a starting relay of the impedence or overload type, and contact 4<1> of a pilot relay 4 the windings 14, 15 of which are, by means of tuning devices 10, 11, made responsive to the carrier and modulating frequencies, respectively, generated at the sources 5, 18 at the far end and fed to the power line by tuning coils 9 and condensers 7. Normally contacts 2<2>, 3<2> and 2<3> are closed so that each end transmits modulated carrier current to the far end, where the currents of different frequency are separated out and fed to coils 14, 15, the resistance 16, 17 being so adjusted that their effects cancel and contact 4<1> remains closed. When neither coil is energized contact 4' also remains closed. With an internal fault at C fed from both ends, contacts 2<1>, 3<1> at each end close and contacts 2<2>, 2<3> and 3<2> open, so stopping the transmission and maintaining the relay 4 de-energized. Contact 4' at each end remains closed and both breakers are tripped If the fault is fed from A only, the transmission is, as before, stopped at A, and contact 4' at B remains closed but as no change occurs in the transmission from B, contact 4' at A remains closed and only breaker A is tripped, the relays at B remaining unoperated. If the fault is bevond B, contact 2<3> at end B opens and 3<2> stays closed. Tripping at B is prevented because 3<1> at B remains open, and the modulation at B is suppressed so that only the carrier of B is received at A. Relay 4 at A is thus energized and opens 4<1> to prevent tripping at A. The Specification also refers to the suppression, or fault, of modulating currents in existing telephone and remote-measuring systems, to the use of two different frequencies instead of modulated carrier currents, and to both currents being received in a single coil for relay 4.

Abstract: 1,079,967. Semi-conductor circuits. ASSOCIATED ELECTRICAL INDUSTRIES. July 5, 1966 [July 7, 1965], No. 28803/65. Heading H3T. [Also in Division H2] An inverter including main thyristors T4, T5 is driven by a square wave oscillator comprising transistors T2, T3 and a saturable transformer. A thyristor T1 connected in the supply to the oscillator enables the inverter to be started or stopped at will. The inverter may be used in a standby power supply, Fig. 2 (not shown). Starting the inverter.-The capacitor C1 is always charged from the D.C. source. When contacts MS1 are closed the contactor coil S is energized and operates contacts S1, S2, S3, so that capacitor C1 is connected to the thyristor cathode by contacts S1 and the thyristor is fired from the positive line through resistor R4 and contacts S3. The initial boost to the oscillator provided by capacitor C1 causes it to start at increased frequency. Zener diode Z2 stabilizes the oscillator supply voltage after the initial discharging of capacitor C1. Stopping the inverter.-Since the current in thyristor T1 reverses briefly at the end of each half cycle, this thyristor turns off automatically when the contactor is released. The inductive energy in the inverter output transformer turns off the last conducting thyristor in the inverter.

Filed: 1938-10-06
Abstract: 502,010. Force - feed lubricators. NEMETZ, G. Oct. 6, 1938, No. 28969. Convention date, Oct. 16, 1937. Addition to 493,399. [Class 12 (iii)] In a lubricant distributer having two pistons 1, 1a, slidable in intercommunicating bores 2, 2a, which cross one another, each piston has a surface which, during the stroke of that piston, bears and slides on a surface of the other piston and prevents the latter from leaving its position. As shown in Figs. 1 and 2, each piston has two notches 16, 17 and 16a, 17a, of cylindrical cross-section corresponding to the radius of the other piston, so that one piston can slide through the notch of the other piston. The pistons could be of unequal diameters. Rotary movement of the pistons is prevented by pins 18, 18a, engaging grooves 19, 19a, in the pistons. In a modification each piston has a boss or projection 23, 23a, of square or other cross-section, and plane surfaces 22, 22a. The sum of the lengths of the bosses measured parallel to the axis of a piston must equal the stroke of this piston. During the relative movements of the pistons the two bosses 23, 23a, move past one another their lateral surfaces coming into contact and the upper surfaces 38, 38a, which nearly reach the plane surfaces 22, 22a, prevent the pistons from turning. To permit assembly the pistons have cylindrical recesses 24a, 25a. In a modification in which the bore 2, 2a do not intersect the bosses 23, 23a, are longer in a radial direction and by engaging longitudinal grooves in the cylinders prevent rotation of the pistons.
