Title: Circuits for double-current data transmission systems
IPC: H04L17/02
Filed: 1972-09-27
Abstract: 1360293 Data transmission: interference suppression; limiters SIEMENS AG 27 Sept 1972 [29 Sept 1971] 44646/72 Headings H4P and H3T A telegraph subscriber or exchange is connected to a transmitter through an input circuit substantially as shown which provides interference suppression, overvoltage protection, and failure indication. Double current input signals on lines a b from the subscriber pass through voltage reducing resistors R1, R2, R3 to the input of a differential amplifier which provides "in-phase" interference suppression. Its output A, double-current referred to earth, may control for example a transmitter which sends one frequency for a mark and a different frequency for a space. Diodes D1 to D4 provide overvoltage protection. The voltage swing at the input terminals of the differential amplifier is limited in both positive and negative senses during normal operation to the emitter-base voltage of transistors 1, 2. Their collectors have a common bond R4 the voltage across which is monitored at S by a threshold circuit (not shown). If the voltage across R4 is greater than a predetermined value, the presence of data at the amplifier input is indicated; but if the voltage falls lower than a certain value then an open circuit fault condition is indicated.

Title: Electrical discharge machining
IPC: B23H1/02
Filed: 1973-09-25
Abstract: 1408337 Electro-erosion MITSUBISHI DENKI KK 25 Sept 1973 [30 Sept 1972] 44877/73 Heading B3V In a method of electrical discharge machining by intermittent application of voltage pulses to the machining gap 1-2, the quiescent interval between the pulses or the duty factor, defined as the ratio of the discharge time to the sum of the discharge time and the quiescent interval, is dependent on the no-load interval of a pulse. The no-load interval of a pulse is detected by a device 9 and measured by a circuit (13), (Fig. 2, not shewn) employing clock pulses from a generator (12). The measured value is fed to a calculating machine (14) which calculates a quiescent time interval using a predetermined function relating the desired discharge and no-load times set by circuits (15, 16) and the actual, measured no-load interval. The calculated quiescent time is fed via any amplifier 11 to control transistors 7A-7N, which control the supply of discharge current to the machining gap 1-2 from a D.C. source 6. The quiescent time is decreased when the no-load interval is greater than a predetermined interval and increased when the no-load interval is less than a predetermined value or zero.

Title: Apparatus for mixing building materials including molten components
IPC: E01C19/10
Filed: 1970-09-22
Abstract: 1318738 Mixers H EGGERATH 22 Sept 1970 [23 Sept 1969] 45031/70 Heading B1C Apparatus for mixing building materials having molten components, e.g. asphalt, comprises a stationary annular trough 11 and a rotatably mounted device 14 carrying rotatable stirrers 12 projecting into the trough and burners 13 for heating the material. The trough has inside liners mounted on asbestos, and is also insulated on the outside. The device 14 also carries additional stirrers 15 which may be inclined and scrapers 16 for scraping the walls and base of the trough, and it is rotatably supported by a central bearing 17 and by rollers 19. The burners 13 are controlled by a temperature sensor located on the stirrers 15 or scrapers 16 to sense the mix temperature. The trough may also be heated by one or more fixed or rotating heating devices, e.g. burners, arranged on the inside and outside of the trough. A cover 20 is provided for the trough, and the stirrers 12 are covered at their tops with bent circular plates to keep the mix from the cover. A silo 23 for material, e.g. sand, chippings and powdered limestone, is connected to a transfer container 25 by an apportioning device 24, the container 25 having an upper stationary half 25a and a rotatably mounted lower half 25b extending from which is a duct 26 leading to the trough 11 and having a control flap therein for closing it during mixing operation. A bonding agent, e.g. bitumen, is supplied to the trough by a spraying or pouring device 27. A hoist 31 feeds the silo 23, and a flue 32 allows escape of gases from the mix via the duct 26 and container 25. The device 14 has its own drive means but it may be rotated by operation of the stirrers 12. To allow for expansion and contraction of the trough 11 it is mounted on slides and is maintained centrally located by stays extending like spokes from the trough to levers which are pivoted on a central housing and are connected to a vertically movable, spring-biased, centrally disposed plate, Figs. 2, 4 and 5 (not shown). During operation the trough 11 is first heated until a temperature sensor switches on the apportioning device 24 to feed material to the trough. The duct 26 is then closed and the bonding agent fed to the trough from the device 27. The mix is removed through opening 47 controlled by a slider or flap. In an alternative form of trough centring means. Fig. 6 (not shown), a central spring-biased plate is connected to the trough by radially disposed cables, chains or belts.

Title: Improvements in or relating to ringers
IPC: G10K1/063
Filed: 1961-12-18
Abstract: 1,008,539. Electric bells; gongs. WESTERN ELECTRIC CO. Inc. Dec. 18, 1961 [Dec. 27, 1960], No. 45242/61. Heading G5J. The armature 60 of a telephone ringer is formed with a groove 62 to engage a pivot pin 56 against which the armature is held by a cylindrical permanent magnet 18. The pivot pin comprises a phosphor bronze rod which is mounted on the base 10 and is contiguous with a pole face of the magnet. The magnet also provides bias for the magnetic circuit, Fig. 7, which includes polepieces 30, 40 and an air gap in which the armature vibrates. The armature is riveted to a clapper rod 67. Alternating current in coil 52 wound around a core 48 in the magnetic circuit causes the armature to vibrate. To reduce noise generated when the armature contacts the polepieces, the armature carried on one side a nylon stud 64 and on the other side a phosphor-bronze sheet 65. The pivot pin 56 is displaced to one side of the pole face of the magnet so that the armature is biased to the extremity of clockwise movement with the strike 68 close to the gong 120. Further bias is provided by a spring 144 engaging one of the notches 75, 76 in an extension of the clapper rod. Bosses 78, 80 and the gong 120 together limit displacement of the armature from the pivot if the ringer is violently treated. The magnetic structure is secured to the base as by plate 108 of zinc alloy and a nut 112 which engages a threaded portion of a post 104 upstanding from the base. Sounding member.-A rectangular gong 120 is secured to the plate 108 by means of a screw 130. Studs 128 in the plate engage apertures 126 in the gong to prevent displacement. Silencing and damping.-A cam 10 mounted on a pivot 84 can be adjusted to any one of three positions defined by indentations 94, 95, 96 in the-base. A finger 86 carried by the cam has a projection which engages an indentation to fix the position. In one position, the cam surface 98 engages a tab on the clapper arm and silences the ringer. In another position, cam surface 100 allows only restricted movement of the clapper arm and, in a third position, the clapper is free.
