Title: Improvements in or relating to telephone systems
IPC: H04M9/00
Filed: 1960-05-16
Abstract: 936,009. Direct-call systems. GENERAL ELECTRIC CO. Ltd., and D. P. ALEXANDER. May 15, 1961 [May 16, 1960], No. 17269/60. Class 40 (4). Connections for effecting two-way conversation may be set up between a first station and any one of a plurality of second stations by manually-operable means at those stations, the connections so set up being, as selected by a caller at any one of the stations, either ones that result from operation of manually-operable means at only the calling station or ones that result from operation of manually-operable means at the called station in response to an indication that the station is being called, which indication results from the operation of manually-operable means at the calling station. As shown, a master station, Fig. 1, is connected to each of a plurality of substations by a separate four-wire line, the equipment shown within the dotted line 1 being duplicated for each substation and the terminals 8, 9, 10 and 11 being connected to terminals 12, 13, 14 and 15 respectively at the corresponding substation, Fig. 2. References containing the letter " O " relate to equipment at the substation. To make a normal call to a substation, the operator at the master station presses a button S2, bringing up a relay A. This starts a multivibrator 22, causing relay F to flash a lamp PA, and operates relay OB (via terminals 10, 14, 15-and 11) which switches on a transistor amplifier 24 and a generator 25 which produces two bursts per second of audio-frequency current. These flash a lamp PO and are heard in receiver 17 as a calling signal. The operator at the called substation answers by pressing button SO1 to bring up relays OD and D, switching off multivibrator 22 and generator 25, producing continuous iliumination of lamps PA and PO, and completing a two-way speech circuit between the substation and channel A at the master station. If button S2 is again pressed, relay E operates to switch the connection from channel A to channel B. Relay X operates on release of button S2, so that subsequent operation of S2 short-circuits relay E and returns the connection to channel A. Lamps PA, PB indicate which channel is in use. Similarly, a substation may call the master-station by use of button SO2, the master-station answering by means of button S1. To cancel a call, button S3 or SO3 is pressed, breaking the holding circuit of relays A and OB (or OA and B). To make a direct call, button S1 or SO1 is pressed, bringing up relays A, OB (or OA, B), D and OD to establish the connection without any action by the called party. The master station may make a group call to all the substations by using buttons GS1, GS2 and GS3 instead of S1, S2 and S3. Specification 936,010 is referred to.
Patent GB-219333-A (GB)
IPC: D01F2/28
Filed: 1924-07-18
Abstract: The stretch-spinning of cellulose acetate silk is permitted by adding to the spinning solution a compound which is extracted more slowly by the salt solution constituting the coagulating-bath than is the main solvent.  Thus, if an acetone solution is to be spun into a calcium chloride-bath, a small proportion of benzene-alcohol, benzene, chlorobenzene, ethyl acetate, pyridine, chloroalcohol or aniline is added to the spinning solution; with an acetic acid solution and a bath of sodium acetate, chloroalcohol or acetylene tetrachloride are suitable additions. Spinning may be conducted in such a manner that only a part of the solvent is extracted in the bath, the remainder being evaporated as the filament passes through the air.  By the employment of these additions, filaments of the order of 3 deniers may be spun from apertures of the order of 0.6 mm.  Specification 194,666 is referred to.

Title: Improvements in or relating to etching of printing cylinders
IPC: C23F1/00
Filed: 1969-04-03
Abstract: 1,259,684. Etching. FRANZ BURDA K.G., and KUSTANNUSOSAKEYHTIO OTAVA. 3 April, 1969 [4 April, 1968], No. 17514/69. Heading B6J. A method of controlling the etching of a gravure printing cylinder comprises etching the cylinder under pre-determined etching conditions, sensing the progress of the etching under the pre-determined conditions and providing a signal representative of the sensed progress, storing a representation of desired etching progress and providing a command signal representative of this desired progress, comparing the sensing signal and the command signal to develop an error signal representative of the difference therebetween, storing functions of changes in etching conditions with respect to etching results in a computer, applying the error signal to the computer to produce control signals based on the functions, and controlling at least one of the parameters of the etching conditions by means of the control signals. Apparatus, Fig. 1.-Fig. 1 is a diagrammatic drawing of the apparatus in which etchant, e.g. ferric chloride, and diluent, e.g. water pass through valves 11, 21, mixer 13a, heat exchanger 13, regulator valve 14, and pump 15 to a tank 74 in which a copper printing cylinder 75, covered with an exposed gelatine layer, is immersed. The level of etching solution in the tank is maintained by means of a manually adjustable overflow tube 72; the cylinder 75 is rotated by a variable speed drive 16, an agitator 19 is rotated by a variable speed drive 18, and a roller 17 is provided which removes etching solution from the cylinder by intermittent contact with variable pressure. Terminals 1 to 8 of a computer unit 40 are connected to respective controls to allow alteration of the etching parameters. The computer is programmed by the manual controls 41, and as a result of etching results obtained from test runs. The cylinder 75 is provided with magnets M, which sweep past a pick-up coil C, and send signals indicative of the position and speed of rotation of the drum through terminal P to other parts of the apparatus. A sensing system includes light source 30, deflection element 36, capable of scanning axially along the cylinder, diaphragm 32, colour disc 33 and photo-electric-cell 31; in normal use, deflection element 36 is stationary and the light beam is reflected from a standard grey-scale 50 through white segment of disc 33 to produce a signal which is fed into comparator 43 provided the magnitude of the signal exceeds a certain level determined by a threshold level setting device 60. The magnitude of the signal depends on the reflectivity of the surface being scanned and will vary during penetration of the etchant through the gelatine layer, and during etching of the cylinder owing to diffusion. Colour filters can be used on disc 33 so that a sudden change in output from cell 31 occurring on commencement of etching of the cylinder, will only then cause the control systems to operate.
