Title: Improvements in heat absorbing glasses
IPC: C03C3/062
Filed: 1931-11-09
Abstract: 387,778. Glass manufacture. JENAER GLASWERK SCHOTT & GEN., Otto-Schott-Strasse, Jena, Germany. Nov. 9, 1931, No. 30974. Convention date, Nov. 13, 1930. [Class 56.] A heat-absorbing glass contains at least 0À2 per cent of ferrous oxide and at least 25 per cent of phosphoric acid (P2O5) or boric acid (B2O3) or of the mixed acids. The silica content is preferably less than that of phosphoric acid. Bivalent oxides, especially those of high molecular weight, small amounts of alkali oxides, colour oxides or rare earths, may be added. The solubility in water is most pronounced with the borate glasses, but by the use of boric and phosphoric acids together and by the addition of at least 10 per cent of alumina, as such or in the form of its compounds, this can be effectively reduced. To obtain a satisfactory reduction during the melting, phosphorus compounds of low oxidation ranging from calcium hypophosphite to phosphides such as Fe3P, or phosphorus itself may be added. According to examples, the percentage of phosphoric and boric acids lies between 60 and 85 per cent and that of ferrous oxide between 2 and 3À75. Silica, and oxides of aluminium, sodium, potassium, magnesium, calcium, barium, zinc, and arsenic are present in some cases. Specifications 192,919 and 312,310, [both in Class 56, Glass], are referred to. The Specification as open to inspection under Sect. 91 comprises also the addition of phosphorus compounds of low oxidation in the manufacture of any glass under reducing conditions.

Filed: 1973-07-02
Abstract: 1425112 Control of printers XEROX CORP 2 July 1973 [10 July 1972] 31500/73 Heading G4H A printer incorporates means for varying the impact of the hammer on a selected type member. The apparatus forming the present invention provides signals indicating the duration of hammer impact, and the " shortest route " difference in position between a newly selected type member and the previously selected member, the signals being used in a servo positioning system (Fig. 3, not shown) for a rotatable wheel carrying radial type members (Fig. 2, not shown). A seven-bit ASC11 word indicating a symbol to be printed is used to access a read only memory ROM43 containing 96 eight-bit words each of which is the twos-complement of the binary number indicating the sequential position of a type member; the most significant bit of each word indicates whether the member is to be struck " hard " or " light " and gates the output from one of two monostables 46 or 47, Fig. 5 (actuated by a print pulse from the positioning system) to a hammer driver circuit. The other seven bits from ROM43 are fed to an adder 57- 58 together with the output from a counter 59 which indicates the type member currently in the printing position. The output # from 57-58 thus represents the position difference between the " old " and the " new " type members; since this could by a number in the range 0-127, logic 61-63 is used to bring # into the range 0-95, corresponding to the 96 type members. To find the difference count # corresponding to the shortest route, either # or 96-# is output as the required difference according as # is less than 48 or not (tested by gates 64, 66). If it is, then # is twos-complemented by gates 68 and added to 96 (in practice, to 32 as only 6 output bits are required), while the output from a bi-stable 73 indicates the required direction of rotation of the typecarrying wheel.

Abstract: 1,109,087. Pulse radar. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 23 July, 1965 [23 July, 1964], No. 31518/65. Heading H4D. In radar video signal transmission for bandwidth reduction the radar echo data in a pulse repetition period is divided into n equal time parts and when passing over an angular sector corresponding to a desired angular resolution only the echoes in one of the n parts is stored whereby over n succeeding angular sectors all the echo signals are written into the store and read-out therefrom for data transmission to the distant point is such that signals are transmitted during the aerial sweep over n angular sectors, the omitted echoes being transmitted during the n - 1 rotations of the radar aerial. In the embodiment n = 3. The radar transmitted pulse train WT is also applied to a divider T1 via a gate Tor controlled by a delayed pulse from a bi-stable FF. Range gating pulses from a divider T3 and trains from divider T1 are fed to AND circuits 1, 2, 3 the outputs from which, via OR circuit 4, are fed to writing pulse generator ST to control the insertion of the radar echo video signals into a line storage unit ZSP, read-out from which is controlled by an output from divider T1. A north-marking pulse is added. At the distant point writing into a storage device is at a frequency corresponding to data transfer speed and read-out is at three times that frequency and takes place only during a third of each reading period, Figs. 5, 6 (neither shown). Real time data transfer utilizing a wide-band channel is available when switches 5 . . . 8 are changed over.

Filed: 1969-06-23
Abstract: 1,222,925. Selective signalling. UNITED AIRCRAFT CORP. 23 June, 1969 [14 Nov., 1968], No. 31626/69. Heading G4H. In an analogue-to-digital converter of the type in which a known voltage is successively modified until it balances the unknown voltage, the known voltage is produced under the control of a shift register 10, Fig. 1, via a D/A converter 18. Initially, as described, a one is set .into the highest stage, stage 4, of the shift register, see cycle 1, t 0 , Fig.. 2, the contents of the register are compared 20 with the analogue input and the result of the comparison X, is set into a result register 24. The contents of the shift register are then shifted with cyclic feedback from stage 1 to stage 4 until the one is detected in stage 0. In cycle 1, this occurs at clock-pulse t. 4 . The one bit having been detected in stage 0, the control circuit is such that (a) the next clock pulse causes a simple shift, without feedback, the bit in the result register being shifted into stage 4, and (b) subsequent shift pulses until the first clock pulse of the next cycle cause shifts with feedback from stage 0 to stage 4, referred to as " long shifts ". Since clockpulse t 4  is the last clock-pulse of cycle 1, the next clock-pulse is t 0  of cycle 2. This causes the simple shift mentioned at (2) above, and also, since gates 14, Fig. 1, are open at t 0  time, a further comparison the result X 2  of which is put into the result register. Clock-pulses t 1 , t 2  and t 3  then cause short shifts, clock pulse t 4  causes a simple shift without feedback, and clock pulse t 0  of cycle 3 causes a long shift. A further comparison then takes place and the result X 3  is put into the result register. This process continues until at the end of cycle 5 the digitized form of the input analogue is assembled in the shift register. Subsequent clock pulses merely cause long shifts and the data can be read out at any time. Upon receipt of a " convert " instruction, the register is cleared, a one is set in its stage 4 and digitizing cycles follow as above.
