Title: Centralized devices for telephone exchanges for converting multifrequency signals into direct current signals
IPC: H04Q3/42
Filed: 1975-01-07
Abstract: 1491941 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 7 Jan 1975 [29 Jan 1974] 571/75 Heading H4K A centralized device shared by a plurality of subscribers lines is provided for converting multifrequency tones received over said lines into decadic impulse trains, and for supplying a decadic impulse train back to the line equipment from which a corresponding multifrequency tone was received. Each subscribers line Z includes a tone detector RV controlling a corresponding switch DV to direct a tone to a concentrator CN, which concentrator supplies a binary representation of the digit represented by the tone together with the address in binary form of the subscribers line on which the tone was received to a memory MR. No details of the concentrator CN are given but it is said to include a number of tone receivers smaller in number than the number of subscribers lines. Once stored in memory MR, the binary digit representation and the line address are fed to one of a number of converters LE detailed in Figure 3 (not shown) where the binary digit representation sets a binary counter C to the complement to 11 of the binary digit. The counter is then set to count up to 16 to produce one output pulse for each count up to 11, whereupon the count between 11 and 16 is used to produce an inter-digital pause. The decadic pulses produced by the converters LE are supplied in TDM fashion on wire E to a matrix AR which in accordance with the line address on wires M 10 -M 1  accompanying each pulse, switches the pulses to an integrator in a peripheral unit PE individual to the line, the integrator deriving a decadic pulse from the TDM pulses arriving from the converter. The decadic pulses are used to operate a relay in the peripheral unit PE so as to signal the digit in loop-disconnect form to step-by-step selectors SG. The matrix AB controls the feeding of information from the memory MR to a converter LE such that a transfer only takes place if the corresponding circuit PE is free i.e. the subscriber is not still signalling. When data is being signalled using multifrequency tones, the information is again stored in binary form in the memory MR and is then transferred via matrix TD to the correct peripheral unit PE.

Abstract: 983,689. Centrifugal separators. SEPARATOR A.B. Jan. 7, 1964 [Jan. 21, 1963], No. 686/64. Heading B2P. An apparatus for separating suspended and dissolved substances from a liquid comprises a centrifuge 1, 2 surrounded by a collecting housing 3 connected to a vacuum suction device and having an outer wall provided with a heating device 5, the suspended substances being separated from the liquid in the centrifuge rotor 1, and the dissolved substances, which are more volatile than the liquid, being evaporated from the centrifuged liquid when the latter is discharged from the rotor into the collecting housing. The apparatus is used for separating dissolved moisture and air as well as free water and solids from spent transformer oil. The heating device 5 may consist of electric heating elements arranged in a chamber 4 surrounding the housing 3 and provided with external heat insulation 14. A viewing channel 12 communicating at one end with the interior of the housing 3 and closed at the other end by a transparent glass pane 13 is provided at one or more points at the periphery of the chamber 4. The housing 3 is connected to the vacuum pump through a pipe 11 and is provided with a liquid discharge device comprising an outer tube 10 open at both ends and surrounding a tube 9 provided with holes which increase in diameter towards its open upper end. The tube 10 prevents foam from being sucked into the pipe 9. A perforated plate or strainer gauze 15 may also be arranged to prevent foam being sucked in the upper ends of pipe 11 and tube 10. In operation, the oil to be treated is fed at 6 through the heating chamber 4 and passes via a pipe 7 into the rotor in which the free water and solids are separated by centrifugal force and may be discharged either intermittently by stopping the rotor or continuously by means of a paring device. The oil still containing dissolved moisture and air is radially discharged above the housing 2 of the centrifuge through an outlet 8 in the form of a fine spray. Due to the vacuum and high temperature prevailing in the housing 3 the dissolved moisture is evaporated and removed with the air through the pipe 11. The oil droplets strike against the heated wall of the chamber and flow down to the bottom of the chamber to be removed through the pipe 9 to a suction pump. The heated wall of the chamber prevents the steam formed from condensing thereon. Specification 983,690 is referred to.

Patent HK-73892-A (HK)
Title: Fastener with interchangeable decoration
Inventor: VIOT JEAN EMILE
IPC: A44C11/02
Filed: 1992-09-24
Abstract: A clasp with an interchangeable ornament includes a generally solid male clasp piece which is split longitudinally in a manner that it is transversely resilient, like a clip. A hollow female clasp piece has an insertion opening and an inwardly indented shoulder or lip at the insertion opening. When the male clasp piece is inserted into the female piece the shoulder of the female piece locks into a groove formed in the male clasp piece. Longitudinally extending slits in the peripheral wall of the female piece makes it transversely elastic and enables it to tightly hold an interchangeable ornamental sleeve that is fitted over the female piece. The ornamental sleeve in turn prevents the slit peripheral wall of the female piece from separating and assures that the inwardly indented shoulder remains locked in the groove of the male piece. Therefore, the male clasp part can not be a pulled out, except by squeezing the male piece to reduce its transverse cross-section to be smaller than the cross-section of the female piece.
