Title: Apparatus and method for routing discrete telecommunication  signals
IPC: H04Q3/52
Filed: 1970-09-18
Abstract: 1326626 Automatic exchange systems AUSTRALIA COMMONWEALTH OF 18 Sept 1970 [25 Sept 1969] 44636/60 Heading H4K.  A telecommunication exchange adapted for switching between TDM highways and arranged to transfer P.C.M. samples from a first time channel on one highway to a second channel on a second highway stores the samples at addresses independent of the particular time channels used on the highways. As shown the highways are arranged in groups SR1 to SRn of eight highways each group being associated with an input group speech memory such as GSM1 and an "output register memory" such as OPR1. Each highway is divided into 25 time slots, 24 of which are used for communication and the 25th for synchronization. Each time slot conveys an 8 bit serial word or sample. At the group speech memory each word is converted to parallel form and fed out on a super-highway HIM comprising 8 parallel conductors (one for each bit) and having 8 times as many time slots so as to be able to cope with all 8 highways of its group. Depending on whether a sample from a first highway is destined for the same or a different time slot on a second highway, the sample is routed via an interhighway HXJ or an intermediate storage interhighway of junctor such as H1J to a superhighway H1R-HNR leading to the group output register of the destination highway. Each junctor highway includes an associative store. A single storage location is used for both directions of transmission, one time slot being used for signals between the first highway and the location and a second time slot being used from the location to the second highway. The addressing arrangement for one highway stores a time address indicating the time slot of the incoming highway and the address of a storage location in which the sample from the incoming highway is to be stored. A comparator compares the time address with addresses successively generated by the exchange clock and on a match being detected the sample is gated from the location given by the storage location address to the highway and a sample is gated from the highway to the location to provide transmission in both directions. The address arrangement for the second highway works in similar fashion. The read in or read out can be inhibited until pre-arranged conditions are fulfilled but no reason for this is given. The junctor can be selected from those which are not involved in a read in or read out step and the storage location can be any which is free and not defective. The highways may be wire or radio links.

Abstract: 1,086,959. Mass spectrometers. GENERAL ELECTRIC CO. Nov. 10, 1964 [Dec. 3, 1963], No. 45801/64. Heading HID. [Also in Division H3] In a magnetic type mass spectrometer the ion beam accelerating voltage is varied by a pulse of combined rectangular and sawtooth form to sweep the mass spectrum. The composite pulse is derived from a circuit (see Division H3) which develops a rectangular pulse from sawtooth pulse and then combines the two pulses, the magnitude and duration of the individual pulses being such that the composite pulse has high and low levels sufficient for two spaced mass ranges in the mass spectrum to be swept while an intermediate range of masses is omitted. The mass spectrometer includes a resiliently mounted ion source assembly composed of a stack of ion source, and ion beam focusing and collimating plates mounted on common support rods to which is also secured the curved analyser tube. The ion source is of the electron bombardment type with a central mesh cage in which the ions are generated. On either side of the cage is an electron emitting filament, one of which is a spare, and a backing plate supports two curved magnetic polepieces located behind the filaments. The ion detector is preferably an electron multiplier with the output lead brought out through an aperture in the side of the envelope to avoid leakage currents.

Title: Discharge mercury vapour lamp dimming system

Filed: 1974-11-04
Abstract: 1449079 Dimming Systems for discharge lamps LUTRON ELECTRONICS CO Inc 4 Nov 1974 [19 Nov 1973] 47544/74 Heading H2H A system for dimming a gas discharge lamp, in particular a high pressure mercury vapour lamp, comprising a capacitor connected in parallel with the lamp is characterized in that the capacitor has a capacitance value of 2 microfarads or less thus enabling the lamp to be dimmed to about 5% of its normal brilliance. A dimming system includes a lamp current regulating device comprising a series connected transistor which is switched on by a control unit so that an increasing current flows through the lamp and its series connected choke and a current measuring resistor. When the lamp current reaches a given instantaneous value, a signal from the current measuring resistor to the control unit is sufficient to limit further increase in the lamp current. The magnetic field in the series choke thus collapses causing current through the lamp to be maintained by means of a free-wheeling diode connected in parallel with the choke, the lamp and the current measuring resistor. Current flow through the diode overcomes a bias voltage in the control unit whereupon the control unit causes the series transistor to switch off and when the field in the choke is dissipated, the bias voltage is re-established so that the control unit causes switch on of the series transistor and the cycle repeats. The dimming circuit is provided with a variable D.C. control signal, the magnitude of which controls the amount of dimming of the lamp. The dimming circuit operates by causing the current flowing through the lamp to increase thus causing, because of the negative resistance characteristic of the lamp, a decrease in the voltage across the lamp, the circuit being such that a stable point, determined by the D.C. control signal, is reached at which no further lamp current change occurs and the adjusted dimming value attained, the minimum value of dimming being dependent upon the value of the capacitor in parallel with the lamp, namely, two microfarads. A further addition to the system is a rapid warmup circuit which circuit operates to increase the lamp current when the lamp voltage is low and to gradually reduce the lamp current as the lamp warms up, means being provided to prevent operation of the rapid warm-up circuit when the lamp dimming circuit is operating.
