Title: Plasma display control apparatus
IPC: G09G3/296
Filed: 1975-02-17
Abstract: 1494509 Matrix displays M J MILLER 10 Feb 1976 [17 Feb 1975] 6699/75 Headings G5C and G4H To fade out gradually the stored display on a gas discharge matrix panel 7 receiving data, e.g. from a computer or radar, successive numbers are generated in a multi-digit, e.g. binary, counter and the X and Y co-ordinates of cells to be successively given erasing pulses are taken in reverse order from the counter, the most significant digits of the co-ordinates from the least significant of the count, giving apparent random clearing of illuminated cells. If the several, e.g. four, most significant digits of the, e.g. 20 bit counter, when matched to a selected set cause termination of the count, illuminated cells not yet addressed scattered throughout the display will not be erased, allowing fade down to a limit selectable by switch from, e.g. 16 levels. The clock frequency determining the rate of fade may be under manual control. In the erase address generator 4 including the counter, the Y erase address digits are taken in order from the last, last but 2 ... &c. digits of the count, but the X erase address may be either the last and last but 1, last but 2 and last but 3 ... &c. with modulo 2 addition in each sum (Fig. 2, not shown), or it may be the last but 1, last but 3 ... &c. (Fig. 3, not shown). The erase address generator 4 may be used with a compatible "tone" (i.e. display brightness) control 3, see Specification 1,494,508, the incoming address data being stored in a buffer in the store 1, together with Z (brightness data), before being read out in entering order to be written under the control of unit 3 governed by the Z data, inhibiting writing to a fraction of the addressed cells identified by their least significant co-ordinate digits x 1 , x 0 , y 1 , y 0 . Writing of data is given precedence by control circuits 8 (Fig. 4, not shown), signalling "busy" while in progress, but when complete allowing unit 4 to sequence through a series of addresses for examination by data checking unit 5 to identify where fixed data is to overwrite the current data.

Patent GB-426023-A (GB)
Title: Manufacture of photographic supports from cellulose derivatives
IPC: G03C1/795
Filed: 1934-03-05
Abstract: Softening agents for incorporating with cellulose derivatives in the manufacture of photographic films comprise a derivative or conversion product from a mixture of fatty acids consisting chiefly of those having 8 to 14 carbon atoms, which derivative or conversion product has no odour or only a faint odour, and, when it is a mixture of esters, consists of aliphatic alcohol-monocarboxylic acid esters.  As suitable parent materials there are specified saponified vegetable fats, particularly coco-nut oil and palm kernel oil, and fatty acids obtained by oxidizing paraffins.  From these materials softening agents are obtained by esterifying the mixture of acids with an aliphatic alcohol, e.g. amyl alcohol, or by reducing it to the corresponding fatty alcohols.  These alcohols may be converted into esters of monocarboxylic acids, or ethers, or halides of the paraffin series.  Before use of the softeners the portions of low and high molecular weight are removed, for example, the first by fractional distillation, and the second by fractional crystallization.  A particularly suitable softener for cellulose nitrate is the fraction of the alcohols obtained by reduction of the fatty acids of coco-nut oil, which boils at 150 DEG  C./13 mm.  The following examples are given.  (1) Nitrocellulose containing 12,2 per cent of nitrogen is dissolved in a mixture comprising the amyl esters of the fatty acids of coco-nut oil, acetone, and ethyl alcohol, and the solution cast into films.  (2) A film is made from a solution containing nitrocellulose, ether, alcohol, and the alcohols obtained by reduction of the fatty acids of coco-nut oil. (3) The alcohols obtained by the reduction of the fatty acids of coco-nut oil of example 2 are replaced by a mixture of monochlorides of the hydrocarbons corresponding to the said alcohols.  (4) Acetyl cellulose and a mixture of alcohols obtained by the catalytic oxidation of liquid paraffin, reduction of the acids to the corresponding alcohols, and isolation of the fraction boiling between 120 and 250 DEG  C., are dissolved in a mixture of methylene chloride, chloroform, and amyl alcohol, and the solution cast into films.  Tables are given of various physical properties of the films of each of the examples.

Patent GB-330528-A (GB)
Title: Improvements in or relating to control systems for direct current reversible electric motors
IPC: H02P7/00
Filed: 1929-03-07
Abstract: 330,528. Langley, E. H. M., and Associated Electrical Industries, Ltd. March 7, 1929. Reversing arrangements.-A continuous current motor for a planning-machine &c., when reversed has the series resistance controlled by an accelerating relay having two coils, one connected across the armature and the reversing contactors, and the other across the supply. The resistance may be cut in or out in stages if desired by using several relays. The procedure for starting a planing machine motor is as follows :-closure of the line switch LS and " start " push button causes energization of the no-volt coil OCNV and closure of contacts NV4, NV1- Contacts NV3 when closed effect the release of the brake (not shown) and NV2 when closed permits the energization of coils OCC and OCC1, the controller being in the "cut" position as shown, and the contacts C and C1 are thereby closed. The closing of contact C closes the switch AXC, whereupon coils OCAC1<1> and OCAC1 of the accelerating relay are energized, by the armature and supply voltages respectively. When the armature E.M.F. reaches a predetermined value, this relay closes contacts AC1 and AXAC1 and opens contacts BXAC1. The closing of AC1 short-circuits the accelerating resistance SR and the series field SF, whilst the closing of AXAC1 results in the closing of contacts AC2 and the opening of contacts AXAC2 and BXAC2. Contacts BXAC1 and AXAC2 now being opened, coils OCC and OCC1 are energized with reduced current through the resistance E. The motor is reversed by the controller being thrown to the " return" position. The contacts C and C1 open and thereby AXC is opened, causing coils OCAC1 and OCAC1<1> to be de-energized. The contact AC1 then opens and causes contacts AXAC1 to open and BXAC1 to close. The opening of contacts AXAC1 de-energizes coil OCAC2, thus opening contacts AC2 and closing AXAC2. As BXC and BXC1 closed when contacts C and C1 opened, and as the resistance E is now shortcircuited, contacts Rand R1 will close, coils OCR and OCR1 now being energized and will close AXR. At this stage the armature E.M.F. is still in the original direction, though the connections have been reversed, consequetly the current in coils OCAC1 and OCAC1<1> are in opposition, and contacts AC1 cannot therefore close until the direction of the armature E.M.F. has reversed and then reached a predetermined value. Alternatively these coils may be arranged so that contacts AC1 cannot close until the armature voltage, is lower than a predetermined value but is not opposed to the supply voltage. The procedure will then be similar to that in the " cut " direction except that in this case the opening of contacts BXAC2 will be effective to de-energize the coil OCFR and hence introduce resistance into the shunt field. The push buttons IPB and IPB1 are for inching, contacts NV5 being closed when the no volt coil OCNV is de-energized.
