Title: Display systems
IPC: H04N3/16
Filed: 1971-06-10
Abstract: 1390769 Cathode-ray tube displays UNITED KINGDOM ATOMIC ENERGY AUTHORITY 2 June 1972 [10 June 1971] 27365/71 Heading H4T  In a cathode-ray tube display system in which characters &c. are produced by intensity modulation of a line scanned raster, distortion of the latter, specifically, pincushion distortion, is corrected by continuous digital adjustment of the X and Y deflection circuits. Fig. 1 shows (in exaggerated form) pincushion distortion of a line scanned raster and Fig. 3 shows a pair of "horizontal" lines 18, 24 and a pair of "vertical" lines 20, 22 enclosing an area in which the character X is to be displayed and the distortion of which is to be removed to provide the rectangular area A 1  (see also Fig. 2), enclosed by the true horizontal lines 10, 14 and the true vertical lines 12, 16. Fig. 4 shows the circuitry employed comprising a horizontal (X) deflection section 30, a similar vertical (Y) deflection section 34, in which elements corresponding to those in section 30 are identified by similar reference numbers with the addition of the letter A and a section 38 concerned with the beam intensity control. Considering the operation of the X- deflection section 30, the Y-deflection operating in identical manner in respect of Y-values, the initial X position co-ordinate is fed, in digital form, to register 70 and via D/A converter 68 provides an analogue input to a summing amplifier 66 feeding X-deflection amplifier 32. Clock pulses from clock 44 are fed to a register 40 providing via D/A converter 38 incremented analogue inputs to a multiplier 48 in which it is multiplied by a quantity Xw in register 50 (see Fig. 3), to provide an analogue product input to a summer 52 the output of which is fed to summing amplifier 66 and a register 58 is fed with pulses occurring at the end of each line trace, the lengths of which may vary, to provide via D/A converter 56 an analogue input to a multiplier 60 in which it is multiplied by the output of a register 62 supplied with a quantity Xi (see Fig. 3), to provide a further input for summer 52. The beams intensity control requirements comprising a variable length group of 16 bit words for each line are fed to a register 80 and a sensing unit 86 controlled by clock pulses via a register 84 derives the actual beam ON-OFF conditions required for a particular character and feeds them to the bright-up control 90. The last 16 bit word in each group carries an additional code which is employed over line 61 reverse the direction of counting of register 40 and to increment register 58 and the second line is scanned in the reverse direction to that in which the first line was scanned and at the end of the second line scan the direction is again reversed (Figs. 5 and 6, neither shown). Vertical lines scanning may be employed, or an oblique raster may be produced; the "mirror-image" of character may be displayed and the system may include means for dynamic correction of focus and astigmastism. Instead of a cathoderay tube other forms of display such as a laser display may be employed.

Title: Ticket printing machine
IPC: G07F13/02
Filed: 1966-06-20
Abstract: 1,117,659. Coin-freed apparatus. KIENZLE APPARATE G.m.b.H. 20 June, 1966 [25 June, 1965], No. 27448/66. Heading G4V. A coin-freed liquid dispenser such as a petrol pump includes a coin sensing device responsive to an inserted coin for stepping a printing roller an amount corresponding to the value of an inserted coin and printing a receipt for the total value of coins inserted. The dispenser is adapted to receive coins of different denominations. Each coin is received in a respective slot in a rotary carrier and transported past a pivoted lever moving a slide 19 a distance protional to the size of the coin. The slide carries a pawl 44 co-operating with a ratchet wheel 35 fast with the printing roller whereby the printing roller is indexed a corresponding amount on return movement of the slide. Reverse movement of the printing roller is prevented by a second pawl 53 co-operating with a ratchet wheel 52 on the printing roller. When the dispenser nozzle is removed from its rest, it releases a pivoted lever 46. The latter is moved counter-clockwise by a compression spring 48. The pawls 44 and 53 are disengaged from their ratchet wheels by a projection 46<SP>1</SP> on the lever 46 and co-operating lugs 45 and 53<SP>1</SP> on the pawls and the printing roller zeroized by a return spring 49. In a modification, the rotary carrier moves the coins over banks of switches to pulse a solenoid controlling movement of the slide, Figs. 7-9 (not shown). Likewise, removal of the dispenser nozzle from its rest, closes a switch to operate a second solenoid controlling the pivoted lever 46. Rotation of a knob 25 lowers a platen 71, whereby a paper strip 29 is imprinted with fixed information from a plate 60 and variable information from roller 34. In addition, the strip is fed from the casing and a knife 73 reciprocated to sever the receipt from the strip.

Title: Improvements in and relating to glow discharge tubes for amplifying, detecting, and other purposes
IPC: B01D3/42
Filed: 1929-09-10
Abstract: 341,064. Discharge apparatus. SEIBT, G., 11, Hauptstrasse, and BLEY, H., 23, Bennigsenstrasse, both in Sch÷neberg, Berlin. Sept. 10, 1929, No. 27475. Convention date, Dec. 5, 1928. Addition to 341,062. [Class 39 (i).] In order to provide an amplified current which is as large as possible in the glow discharge tube described in the parent Specification whilst maintaining the full screening effect of the discharge anode as described in Specification 341,063, the cathode is constructed as a grid, network or sieve. By this means, as shown in Fig. 2, the number of sources from which the amplified current to the amplifying anode a<2> can be drawn, is increased. The discharge anode a<1> is arranged at a distance of about 5 mm. from the cathode k and comprises a metal sheet in which are stamped holes or slots registering with but smaller than the holes in the cathode. The controlling electrode s comprises a wide mesh net or a spiral. The cathode may consist of a number of wires arranged parallel to each other. Fig. 4 illustrates a concentric arrangement of electrodes. It is explained in the Specification that it is an advantage to locate the cathode k inside the other electrodes by reason of the greater spaces between the individual parts of the discharge anode and consequent reduction in the number of electrons which are attracted to the discharge anode a<1>. Fig. 6 shows a constructional form of the invention. The leads h are surrounded by insulating sleeves to avoid discharges between them. The electrodes may be supported in concentric grooves in a steatite or other body.

Title: Process for the preparation of 17-esters of 17alpha,21-dihydroxy steroids of the pregnane series and products obtained
IPC: C12P33/18
Filed: 1974-11-12
Abstract: 1461663 Preparing 17-esters of 17α,21-dihydroxy steroids LARK SpA 12 Nov 1974 [4 Jan 1974 (2)] 27543/74 Heading C2U A 17 - monoester of a 17α,21 - dihydroxy steroid is prepared by esterifying the corresponding 17α,21-dihydroxy steroid 21-phosphate with a carboxylic acid, a carboxylic acid anhydride or a carboxylic acid chloride under mild conditions, then dephosphorylating the intermediate 17-acyloxy-21-phosphate by enzymatic hydrolysis using an acid phosphatase at a controlled pH. The acylating agent preferably contains up to 11 C atoms and may be mixed with a diluent. An aqueous suspension, dispersion or solution of cells or tissues or their fragments or constituents, particularly of rice bran, is preferably used for the dephosphorylation carried out in an acidic medium, particularly pH 4-5, and at 10-50 C. The enzymatic dephosphorylation may be carried out on the esterification reaction mixture without isolating the 17 - acyloxy - 21 - phosphate. The 17- monoesters obtained may be further esterified to 17,21-diacyl-esters with the acyl residues being the same or different. Forty-one compounds falling within the formula are novel, where R 1  is H, F, Cl, CH 3  or CF 3 ; R 2  is H, OH, CH 3 , methylene or halomethylene; R 3  is H, CF, F, OH, or keto; R 4  is H, F, Cl, Br, CH 3  or methylene; X is H, F, or Cl and R ester groups include formate, acetate, propionate, butyrate, isobutyrate, valerate, isovalerate, caproate, caprylate, palargonate, aenanthate, and benzoate.

Title: Improvements relating to telephone and like signalling systems
IPC: H04Q1/36
Filed: 1939-10-10
Abstract: 533,113. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., CLAY, D. L., BARTLETT, C. J. C., and CHITTENDEN, P. A. Oct. 10, 1939, No. 27576. [Class 40 (iv)] In an impulse repeater in which the lines are coupled by the transformer action of a repeating coil, one or more non-linear resistances such as metal rectifiers or elements of a known silicon-carbide resistance material are associated with one or more windings of the repeating coil to absorb surges. Circuit arrangements. Line relay A, Fig. 1, is of the high-speed type described in Specification 405,436, [Group  XXXVII], and controls a similar repeating relay AA. Release relay B energizes a switching relay HA and a meter-controlling relay G and relay C improves the impulse current during each digit. A resistancecondenser combination is connected across the repeating contact. Rectifier MRB prevents the connection in shunt of B from affecting the release time of AA. Rectifiers MRD shortcircuit the back-bridge relay D during the setting up of the connection. Non-linear resistances SR1, SR2 are biassed by the voltage drop in resistances R1, R2 due to the line current so that normally they do not pass current. At each impulse, however, they act as shunts to absorb energy stored in the windings I, III of the repeating coil. When the called party replies, D energizes DD which has a long operating lag. DD connects up booster battery and releases G which energizes H to terminate the booster impulse. When the calling party clears, the relapse of A, AA opens the outgoing circuit whereupon D, DD fall, if they have not previously been released by the called party, and relays C, G are energized before B has had time to fall back. When the relapse of B removes ground from the private wire, HA falls and replaces it for a short time until G and C have fallen. By this means the circuit is guarded temporarily after the release of the preceding switches has been initiated to give ample time for the release of apparatus ahead before the repeater can be seized. In a similar repeater, Fig. 2 (not shown), impulses are repeated in voice-frequency form, relays A, AA in this case being connected in series. A single surge absorbing non-linear resistance may be bridged across the outgoing side of the repeating coil to replace the elements SR1, SR2, Fig. 3 (not shown). In other arrangements, Figs. 4 ... 6, the non-linear resistances are connected to an additional winding of the repeater coil or a pair of separate windings.
