Abstract: 1,120,436. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 13 Jan., 1967 [3 Feb., 1966], No. 4841/66. Heading H4K. In a code point translator for translating subscriber dialling codes into equipment codes, two digits represented by a pulse and a bias on one out of ten lines respectively, enable one out of a hundred " pulse plus bias " gates each incorporating ten diodes connected one in each of ten corresponding code wires forming a group associated with that gate; and a third digit represented by a pulse applied to the other end of one code wire of each group switches one diode in the enabled group thus passing a pulse down one out of 1000 code wires. As described the code wires are each threaded through different combinations of magnetic cores RC as in Specification 1,120,435. The units digit is applied at U in 2 out of 5 code and is converted to one out of ten and applied to pulse receive gates PRG as indicated. The tens and hundreds digits signals are similarly decoded and applied to pulse drive gates PDG and bias gates CCG respectively. All three sets of gates have additional inputs controlled by a timing arrangement shown at the right of the Figure. As described there are five translators such as that shown in Fig. 1 and each timing arrangement is wired as indicated at TH to operate its associated translator only on reception of its particular thousands digit. The " pulse plus bias " gates FDG each include a resistor in the bias input and a capacitor in the pulse input. To allow for rapid operation a monostable multivibrator MA1 is triggered for each operation of the translator switching on the pulse drive gates and pulse receive gates thus clearing any residual charge on the capacitors.

Filed: 1976-02-09
Abstract: 1508722 Refrigerators; defrosting KYSOR INDUSTRIAL CORP 9 Feb 1976 [7 Feb 1975] 05029/76 Heading F4H An open-fronted display case employing a multi-layer air curtain across the access opening is defrosted by drawing ambient air through passages in the cabinet through which, in normal operation, the air for the inner layer passes. As shown in Fig. 1, the air forming the inner layer passes through an inlet 32, and a passage 30 containing fans 40 and evaporator coils 38 to an outlet 36. Air forming an outer guard layer passes through an inlet 48 and a passage 44 containing fans 54 to an outlet 52. A third layer of the air curtain may be produced by passing ambient air from inlets 56, containing fans 60, through a passage 62 to an outlet 66. During defrosting, the refrigeration system is de-activated and ambient air is drawn through the inlet 32 by the fans 40 and passes through the passage 30 and exhaust passages 71 to a plenum chamber 72 containing fans 98 and open to atmosphere through openings 82 which, during normal operation, are closed by doors 86. At the same time, ambient air is drawn through the outlet 36 to the plenum chamber. When the resistance to air flow through the evaporator coils 38 diminishes, the greater propulsive capacity of the fans 40 relative to that of the fans 98 causes part of the air flow to pass through the plenum chamber and part to pass through the upper portion of the passage 30 to the outlet 36. The defrost period is initiated by a timer and terminated by a thermo-disc 83 and the process may be speeded up by the provision of electrical heaters at the inlets and/or outlets.

Abstract: 977,565. Feeding webs. CROSFIELD ELECTRONICS Ltd. Feb. 7, 1963 [Feb. 13, 1962], No. 5495/62. Heading B6B. [Also in Division G1] A printed web 3 from an expiring roll 4 is spliced to a printed web on a replacement roll 2 by a brush 9, the operation of which is controlled to preserve correct registration of the printed patterns of the webs. A strip of magnetic foil is secured by adhesive to the periphery of the roll 2 at a determined position in relation to the printed pattern thereon. The strip 15 is detected by an electromagnetic sensing device 16 connected to a pulse generator 17, while a photo-electric detector 12 senses register marks 10 on the expiring web 3. The detector 12 is connected to a pulse generator 14. Both pulse generators are connected to a register detector 13. When signals from the sensing device 16 and detector 12 are in coincidence the detector 13 initiates splicing, such that the brush 9 is actuated to press the web 3 against roll 4, thereby causing an adhesive area 5 to stick to the web 3 and a securing tab 6 to be torn. A knife (not shown) is also actuated by a signal from the detector 13 to cut the expiring web 3 after splicing. The device 16, Fig. 2, comprises a soft iron core 20 energized by a winding 21, thus generating a magnetic field 23. Passage of the strip 15 produces a small electromotive force of waveform 26 in a coil 25 by producing a disturbance in the field 23. The signal is fed to a linear amplifier 29 and a trigger circuit 30 which produces an output pulse of short duration. The strip 15 of magnetic foil may be replaced by a strip of magnetic ink or tape.
