Title: Improvements in and relating to copying machines
IPC: G03G15/22
Filed: 1967-08-15
Abstract: 1,149,539. Delivering sheets. RICOH K.K. 15 Aug., 1967 [14 Nov., 1966], No. 44691/67. Divided out of 1,148,087. Heading B6H. [Also in Division G2] In a sheet-separating mechanism operating as described in Specification 1,148,087, the original and copy sheets O, S, after leaving the printing cylinder 1, initially pass between a pair of rollers 8, 9 mounted on respective shafts 20, 21. Roller 8 rotates at the same speed as cylinder 1, but roller 9 rotates at a faster rate, so that the frictional force of roller 9 on copy sheet S causes it to separate from the original O Thus the leading edge of sheet S is then slightly in advance of the leading edge of sheet O, so facilitating entry to the sheet-separating mechanism proper. When sheet S becomes taut between roller 9 and the printing cylinder (position of Fig. 2), a slippage mechanism comes into operation, causing roller 9 to rotate at the same speed as roller 8. This is shown in more detail in Fig. 4. Shafts 20, 21 carry a plurality of rollers 8, 9, staggered as shown. Shaft 20 is driven by a gear-wheel 28 fixed to it. A gearwheel 22 is loosely mounted on shaft 20, and can be frictionally engaged with it by a friction ring 24b. Such engagement is made by forcing gear 22 against ring 24b and gear 28 by a spring- urged pressure-plate 25 acting against the other face of gear 22. The pressure exerted by spring 26 on plate 25 can be varied by a nut 27. Shaft 21 is driven from shaft 20 by engagement of gear 22 with a gear 23 fixed on shaft 20, and since gear 23 is smaller than gear 22, shaft 21 rotates at a faster rate than shaft 20. When, as a result of sheet S becoming taut, roller 9 (and hence shaft 21) is constrained to rotate at the same rate as roller 8 (and hence shaft 20), slippage occurs between gear 22 and shaft 20.

Abstract: 992, 477. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 27, 1963 [Nov. 28, 1962], No. 46845/63. Heading G4C. A circuit for storing digital data in m out of n code, includes a first set of n gates, a selected m of which are opened to indicate the code, and a second set of gates which constitute feedback paths, which maintain the first set of gates in their set condition after the setting signal has been removed. Circuits for storing in 2 out of 4 and 2 out of 5 code are detailed. As shown a 2 out of 4 code circuit comprises four 'OR-inhibit' gates 11, 12, 13, 14, which can be set to any one of the six possible 2 out of 4 combinations by a setting signal on one of six lines A, B, C, D, E or F e.g. if A is enabled, outputs are produced on lines 23, 24 but non on lines 21, 22. The outputs 21-24 are fed back in various combinations to a set of AND gates 15-20 and in the example given AND gate operates to maintain the inputs to the gates 11, 12 even after the input at A is removed. The state of the gates 11-14 can only be changed by another signal on one of the lines B-F. The OR and AND gates may be interchanged; i.e. OR, AND-invert logic can be used.

Abstract: 1,083,332. Transistor circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION March 11, 1964 [Dec. 12, 1962], No. 46897/62. Heading H3T. [Also in Division G4] In a circuit for processing a waveform which represents a quantized variable having unwanted spikes the duration of which is short compared with the data rate, the instantaneous value of the input waveform is compared with that of an output waveform, a signal being generated the polarity of which is dependent on the polarity of the difference between signals being compared but of magnitude independent of the magnitude of the difference and means are provided responsive to said signal for causing the output waveform to follow the input at a rate which is slow compared with the rate of rise of unwanted spikes. The invention is applicable to a digital time base circuit for a radar system. As described, signals at 1 represent the ordinates of sin and cos modulated saw-tooth waveforms required for a PPI radar display and are converted at 2 to pulse frequency modulated signals, each of which is converted at 5, 6 to the corresponding analogue step which is amplified by transistors LTP1, LTP2, Fig. 2, and used to control switching transistors TA1 . . . TA4. Capacitor 12 is charged with a polarity dependent upon which transistors of the pairs TA1 . . . TA4 is conductive. The voltage across the capacitor 12 is converted by transistors 21 . . . 23 to current which is fed back to the input A so that the voltage across the capacitor tends to follow levels of analogue steps from 6, but smooths out the interstep transitions. Voltage limiters 18, 19 are provided. Inter-scan markers may be inserted at 15, a smaller capacitor 12 being switched in during such periods. Fig. 3 (see Division G4) depicts a digital/analogue converter.

Title: Method of producing vapours of controlled composition
IPC: B01D3/34
Filed: 1962-12-13
Abstract: In the continuous production of a vapour mixture of constant composition by the evaporation of a solution 5 of two or more components, the composition of the solution is maintained constant throughout the evaporation <FORM:1031519/C1/1> by the flow of a second solution 6, which is richer in the more volatile component(s), into the evaporator 1 from vessel 2 via line 3 and one-way ball valve 4.  The ratio of the surface areas of liquid in evaporator 1 and vessel 2 is determined by a specified mathematical formula. The evaporator may be achieved by heating the solution 5, or by bubbling a carrier gas through it via tube 10.  The vapour mixture generated in evaporator 1 may be used to produce a solid layer of material on substrate 12 in vessel 13, either by condensation or thermal decomposition. Example 1 relates to the production of the compound V3Si by the thermal decomposition of a vapour containing 3 mols. of VCl4 to 1 mol. of SiCl4 carried in hydrogen gas. Example 2 relates to the production of an epitaxial layer of silicon, containing 5 x 1017 atoms of phosphorus per cm.3, on a single crystal silicon substrate.
