Title: Buffer Data Storage System Using a Cyclical Memory
IPC: G06F3/06
Filed: 1966-09-01
Abstract: 1,153,066. Buffer storage system. VOGUE INSTRUMENT CORP. 1 Sept., 1966 [7 Sept., 1965], No. 39158/66. Heading G4C. The storage location to store the next data input and the location storing the next data output in a buffer storage system comprising a memory the contents of which are circulated in a closed loop are both located with reference to addressing means storing diserete address words cycling in synchronism with said memory. Digital data messages read-out from main storage tracks 26 of a magnetic drum store 20 at random intervals are temporarily stored in buffer store tracks 60 of the same drum store before being read-out at a slower rate on a first-in-first-out basis to an output device 86 which may be a teleprinter. Transfer requests originate from a console 42. Each time a message is read into the buffer store an input counter 52 is incremented by one. Each time a message is read-out from the buffer store an output counter 54 is similarly incremented. The temporal values of these counters are compared with the addresses read from an address track 22 on the drum 20 to determine the position in the buffer tracks for writing to and reading from respectively. The address track comprises a sequence of serially recorded binary-coded decimal numbers running from 00-99. Whenever comparator 100 detects that the values of the input and output counters agree-indicating that all messages in the buffer store have been read out-both counters are reset to zero so that the next message received is recorded in the first message slot. Indicators are provided for indicating when the store is (say) 60% full and when it is empty. Further transfer into the store is prevented when the last storage slot has been filled. As the outward transfer is slower than transfers in the other direction, an output operation may be interrupted by an input request and the apparatus idles in a condition ready to transfer out. Each data message comprises five words recorded in parallel tracks as shown in Fig. 2 which also illustrates the staggered relationship between the address words in track 22 and the corresponding message slots. Each track can accommodate 100 seven-digit words, each digit comprising four (binarycoded decimal) bits and one parity bit. Parity checks are made, including checks on the parity of the address words, further transfers-in being prevented if an error is detected until all messages have been read out and the counters zeroized. The five words of a message are transferred serially in turn to an output shift register 90 and serially by bit from there to the teleprinter 86. The source of the messages is a plurality of machine stations 24 as described in Specification 1,142,622. Detailed circuitry is described with respect to Figs. 3-6 (not shown).

Abstract: 1284086 Silica gel NATIONAL DISTILLERS & CHEMICAL CORP 5 Aug 1969 [6 Aug 1968] 39240/69 Heading C1A A silica xerogel is prepared by a process in which (1) a silica hydrogel is formed by (a) reducing the pH of an aqueous solution of sodium silicate to provide a silica hydrogel slurry having an SiO 2  concentration of from 5 to 12 wt. per cent and a pH of from 3-8, the temperature during such precipitation being maintained between 0 C. and 10 C.; (b) heating the product of step (a) at a pH of from 3 to 8 and at a temperature of from 50 to 100 C. for from one to six hours, and (c) washing the product of step (b) to remove sodium until the filtrate contains less than 20 p.p.m. by wt. of sodium salt; and (2) converting the hydrogel to a xerogel, by (d) replacing the water in the hydrogel by a liquid of lower surface tension and (e) thereafter drying the gel. By this process a gel having a surface area of from 200 to 500 m.<SP>2</SP>/gm., the majority of which is provided by pores of a diameter of from 300-600 C. and which is stable at temperatures up to 1100 C. in a fluidized bed. The water in the hydrogel may be replaced with a water miscible organic liquid, selected from, for example, alcohols, acetone and mixtures thereof. Alternatively, a surface-active agent may be added to the gel. Step (a) of the process may be accomplished using acids, e.g. HCl or H 2 SO 4 , or using ion exchange resins. In step (a) 40% of the necessary amount of pH reducing agent may be added over a period of 30-120 minutes, e.g. 1 hour, and the balance added during a subsequent period of 20 to 90 mins., e.g. 45 minutes. The silica concentration in the hydrogel precipitate may be from 8 to 9% by weight and the temperature during steps (a) and (b) may be 5 and 90 C. respectively, the preferred pH range being 5 to 7. Step (b) may occupy a period of 4 hours and the washing of step (c) may be accomplished using solutions of aluminium chloride, aluminium sulphate, ammonium chloride, and ammonium nitrate, or solutions of HCl or H 2 SO 4 . Drying step (e) may be accomplished by spray drying or by distillation. Before or after step (d), the gel may be comminuted to a particle size less than 200 microns. If desired, the dried xerogel may be calcined at a temperature of 260 to 650 C.

Abstract: 896,745. Valve pulse circuits; radar. COLLINS RADIO CO. Nov. 15, 1960 [Jan. 15, 1960], No. 39252/60. Classes 40(6) and 40(7). [Also in Group XL(a)] In the operation of a direct-viewing storage cathode-ray tube (see Group XL(a)) for use in a P.P.I. radar display system a positive going storage image erase pulse is applied to the storage mesh 11 at the end of the writing beam sweep signal slightly delayed with respect to another pulse used for decreasing the voltage applied to the viewing screen 12. The signal generator 31 produces in addition to the sweep signals a train of rectangular shaped pulses which are applied to differentiating circuit 34, 35. Triggering pulses are derived at terminal 36 for a one-shot multivibrator circuit which includes a normally conductive triode 41 and a normally non- conductive triode 42. The triode 41 becomes non-conducting and the resulting positive increase in the voltage of anode 81 is applied through coupling capacitor 74, conductor 89 and resistor 76 to the grid of normally non- conductive triode 78. This triode 78 then conducts and the viewing screen potential derived from source 79 is effectively shunted to ground potential. When triode 41 begins to conduct again storage capacitor 57 produces a surge of current through the valve and through the common cathode resistors 43, 44 of the multi-vibrator circuit. An erase pulse derived at tap 51 is applied through coupling capacitor 61 and blocking diode 62 to the storage mesh 11. Diodes 63, 64 form clamping circuits which limit the upper and lower valves of the erase pulse.

[Class 92 (ii).] Relates to sights for guns on aircraft especially for firing at ground targets and provided with a cam device for correcting the angle of tangent elevation for varying angles of sight. According to the invention, a cam 22, Fig. 1, is provided below the back-sight 8 and is adapted to be levelled about its axis 10 by an adjusting knob 28 on a link 27, a level 26 on an arm 25 on the cam indicating the level position ; a telescopic link 31, 32 co-operating with the face of the cam is pivoted at 30 to the short arm 49 of a bellcrank, the other arm 16 of which carries a slide 15 adjustable to a scale of height on the arm 16 ; and the slide 15 carries by means of a swivel 14 and a slide 12 the front end of the sight bar 7, the rear end of which is pivoted about the axis 10. By means of this arrangement, the angle of tangent elevation is corrected as the gun is depressed to follow the ground target, the bell crank 49, 16 multiplying the effect of the cam 22. The device is rendered ineffective by adjusting the slides 15, and swivel 14 co-axially with the bell-crank as shown in Fig. 1. The bell-crank may be replaced by a lever with an adjustable fulcrum. The back sight is adjusted for range by elevating a sleeve 11 by a range drum 50 up a post standing on a slide 34 adjustable for own speed on a leaf 35 by a screw 36.
