Title: System for disabling incoming telephone calls
IPC: H04M1/66
Filed: 1972-12-13
Abstract: 1409819 Substation equipment J ST CLAIR KILBY 13 Dec 1972 [30 Dec 1971] 57467/72 Heading H4K A substation includes an arrangement for responding to an incoming ringing signal and for reverting a signal which simulates the telephone system busy tone so as to warn the caller that the wanted party is temporarily unavailable. The response to ringing may be effected manually by the station owner who depresses a button or speaks into the microphone of a voiceoperated relay thereby causing the line to be looped and the busy tone to be transmitted. In the fully automatic arrangement shown, the subscriber depresses one of switches 250- 253 in dependence on the time period, e.g. 3, 10, 30 or 60 minutes, for which he does not want to be disturbed. A particular gate 262-265 is thereby partially enabled so as to reset the apparatus when a clock pulse (232) driven counter 234, 236, 238, 240 reaches the desired count; one of lamps 270-273 is turned on by its associated transistor driver 266-269; and a ringing detector 166 is enabled by the reverse biasing of diode 177. The first burst of incoming ringing is effective to turn-on transistor 176 and thus in turn transistors 182, 184 which thereby enable relay 156 to loop the line. NAND circuits 200, 202 are energized by the turn-off of transistor 210 so as to reproduce respectively the cadence and frequency of the system busy tone. This tone is sent to line for a period, e.g. 25 secs., determined by unijunction transistor 194 which is effective after this period to turn-on 196 and turn-off 184, 182 prior to its own de-energization. The apparatus preferably responds to ringing before the subscriber's bell set is energized although the possibility of providing a visible or audible warning of incoming calls is mentioned. Switch 280 serves to override the 3-60 minute timing circuits. In the manually actuated embodiinent of Figs. 1 and 2 (not shown) the NAND circuits are replaced by conventional multivibrators.

Abstract: 1,148,950. Concentrating silica sols. MONSANTO CHEMICALS Ltd. 5 Dec., 1967 [23 Dec., 1966], No. 57649/66. Heading C1A. Aqueous silica sol is concentrated by placing it and water or an aqueous solution respectively in two compartments separated by a semipermeable membrane, and a pressure difference is established between the opposite sides of the membrane resulting in a net transport of water out of the sol. When the other liquid is water, said transport is achieved by applying pressure to the sol, and when the liquid is an aqueous solution of a salt, the transport is caused by osmosis. The membrane is preferably of cellulose acetate, on a suitable support, and has water permeability of 40-500 U.S. gallons/ sq. ft./day at applied pressures of 50-900 p.s.i. The sol may be made by any means, and is preferably treated with a cation-exchange resin to reduce its pH to achieve higher throughput of the membrane, which may be further increased by treating the sol with a cation and an anion-exchange resin, in that order, prior to the concentration process.

Abstract: 1329114 Analyzing radiation BARRINGER RESEARCH Ltd 9 Dec 1970 [15 Dec 1969] 58444/70 Heading G1A In an apparatus for analyzing radiation of the spectra of a particular substance, the radiation is dispersed to form, on the basis of its spectral content, a pattern of zones of high and low intensity in a plane, and the pattern is then investigated to see if it corresponds to a pattern characteristic of the particular substance. In one embodiment, Fig. 5, suitable for examining the terrain beneath a space craft, the incident light 42 is collimated by a lens 43 and directed towards a pair of wedges 44, 45 which produce two sets of interference fringes in a plane containing a pair of masks 46 and 47. Each mask is transparent with a series of opaque lines thereon, in one mask the opaque lines correspond to the zones of high intensity radiation characteristic of the particular substance; in the other mask the opaque lines correspond to the zones of low intensity radiation characteristic of the particular substance. The number of lines on both masks are such that the masks have the same overall transmissivity. Therefore, when the spectra of the incident radiation is present, a difference in outputs of photo-detectors 50 & 51 will result. The difference is fed into a differential amplifier 52 and a conventional amplifier 53 and displayed on a meter 54 or a pen recorder 55. In a similar embodiment, Fig. 6 (not shown), the outputs of the photo-cells are fed to a summing amplifier and to a difference amplifier, the outputs of each amplifier being passed via respective high pass filters to a ratio detector 59 whose output is fed to a meter or pen recorder. In another embodiment similar to the first embodiment, Fig. 2 (not shown) only one optical wedge and photo-detector is employed and the masks are fixed on to a rotatable disc. The resulting alternating signal is processed by a synchronous detector and an integrator.. In a modification, Figs. 7, 8 (not shown) two patterns corresponding to the high and low intensity zones are formed direct on a single substrate by sensitizing desired areas through doping. The patterns are either formed side by side or are interdigitated. The differing outputs are then processed in a similar fashion to above.

Abstract: 1293908 Meter reading KENT METERS Ltd 11 Dec 1969 [11 Dec 1968] 58977/68 Headings G4D and G4H In a meter station comprising a totalizing register, a reversible register advanced with the totalizing register, and a means for decrementing the reversible register from a remote station until its total is between zero and minus one, the decrementing may be completed independently of any increase in the total to be accumulated. The reversible register is driven by a mechanical drive which includes a differential gear from the totalizing register, Fig. 1 (not shown). The reversible register is decremented by a solenoid operated ratchet, which is driven by pulses from a remote interrogating station. Each decade of the reversible register has a recess on its surface and an elongated cam surface extending across the width of the register decades drops into the recesses when they are aligned. The cam is used to break a contact and prevent further pulses from being transmitted to the ratchet device. The number of pulses required to bring the reversible register back to zero is counted at the interrogating station. In an embodiment, Fig. 4, which allows faster interrogation, a read-out switch 83 is closed and relay 84 is energized, assuming switch 61, which is opened by the cam when the reversible register has been zeroed, is closed. The contacts 85 and 86 are thus closed and the ratchet solenoid 62 operates through one half count. The motion of the relay 62 moves the switch 64, thus interrupting the supply to coil 84 via conductor 94 but not via conductor 93. The battery voltage is applied via conductor 95 to the coil 90 which causes the switch 89 to move into its alternative position. This action removes the current from the relay 84 via conductor 94 and energizes coil 87, thus causing contacts 88 to open, and the latching supply to coil 84 also to be broken. The de-energization of coil 84 causes contacts 85 to break, thus de-energizing the register solenoid 62, which causes switch 64 to return to the illustrated position and energizes coil 90 to effect the second half count. The circuit is thus in its original state and the cycle repeats until the switch 61 is opened by the cam. The coil 90 is used to activate a counter to record the number of pulses required. The count may be displayed at the interrogating station.
