Title: Improvements in or relating to the testing and repair of electronic digital computers
Inventor: LAWDER ROBERT ERNEST
IPC: G06F11/22
Filed: 1966-03-25
Abstract: 1,131,085. Testing computers. SECRETARY OF STATE FOR DEFENCE. 22 March, 1967 [25 March, 1966], No. 13231/66. Headings G4A and G4C. A method of testing an electronic digital computer of a type having a control section provided with micro-programming parts, a registers section (including registers, adding devices and gates) and a memory section, to detect the presence of and locate the sources of faults in the operation of the computer, includes the steps of substantially disconnecting at least the micro-programming parts of the control section from the registers section and from the memory section of the computer or otherwise rendering the micro-programming part of the computer temporarily inoperative; feeding to the registers section a sequence of signals designed to exercise all important normal actions of the parts of the registers section in such a sequence that already tested parts are used in testing further parts and so that the correctness of each action or of each of a plurality of short sequences of actions may be verified; and then testing the storage location of the memory section for their ability to receive and reproduce number signals correctly. The correctness of actions may be verified by a monitor displaying the contents of a part of the registers section and also by adding a signal to be checked to the complement of its correct value and detecting the presence of any zero signals. The storage locations are tested by connecting the registers section to the memory section and applying a sequence of signals so that in sequence the storage locations are filled with a first pattern of ones and zeroes, the storage locations are read out and checked against the original pattern, the storage locations are refilled with a second pattern of ones and zeroes which is complementary to the first pattern and the storage locations are again read and checked. Instruction modifying outputs of the registers section may be connected to inputs of the registers section so that their correctness may be verified. The operation of the control section may be checked by feeding a sequence of instruction signals from a punched tape to the control section and checking the control signals emitted by means of complementary reference signals or by connecting them to data inputs of the registers section, summing the signals as they are emitted and comparing with reference totals. Detection of a fault may shut off power supply connections. Detailed circuit arrangements for carrying out the method of testing are described with reference to Figs. 1-8 (not shown).

Title: Improvements in or relating to apparatus for feeding sheets
Inventor: JACKSON DONALD RICHARD PATRICK
IPC: B65H3/08
Filed: 1956-05-01
Abstract: 822,613. Feeding sheets. JACKSON, D. R. P., ROFFEY, W. A., and MOLINS MACHINE CO. Ltd. April 30, 1957 [May 1, 1956], No. 13413/56. Class 100(1) A magazine 8, 9, for slit sheets, such as pocket blanks, which are separated individually from the bottom by pneumatic means, is inclined at 30 degrees to the vertical and provided with pile supporting lugs such as 11, 13, and has at one side 9 a restricting member 43 which holds up most of the pile at that side so that excessive pressure is not exerted on the lugs 13, but allows the sheets to fall past it as sheets are removed from the bottom of the pile, The member 43 is a narrow resilient bar, secured to the top of the side 9, which is pressed away from the side by a screw 44. Sheets below the end of the member 43 are wholly supported by the lugs 11, 13, but those above this lever are supported at one side by the sheets beneath them and at the other side by the member 43. As the level of the sheets falls below the end of the member 43 due to the removal of sheets from the bottom of the pile, the sheets immediately above this level can slip past the end of the member. The lugs 11 are bent to lie in a horizontal plane to facilitate removal of the sheets. sheet-separators and forwarders. The front edge of the bottom sheet is pulled down by suckers, and a drop-roller 38 presses it on conveyer bands 40 so that the sheet is pulled completely from the pile, and forwarded by the bands 40 and upper bands 39. The sheets are blanks for making pockets as disclosed in Specification 507,998 [Group XVII], and are separated by a suction body 18 provided with three suction members 19, 20 (not shown), and 21 which are positioned to suit the shape of the sheets and the slits therein. The body 18 is connected by a flexible tube 22 to a valve 23, secured to a rotating shaft 24, which connects this tube to a further tube 25 leading to a source of suction. The body 18 is mounted on an arm 26, pivoted at 27, which is rocked by a cam 31 on the shaft 24: a further cam 32 reciprocates a connecting link 34 to rock a lever 35, pivoted at 37, carrying the droproller 38. The two suckers 19, 20 are in alignment, and the sucker 21 is disposed near to the wall 9, and engages a small portion of the bottom sheet which is separated by a slit from the main portion of the sheet and is not supported by lugs on the magazine. The unsupported small area of the bottom sheet is thus pulled downwardly from the magazine by the sucker 21 before the rest of the sheet, and ensures that two adjacent sheets do not interlock and are separated together from 'the pile.

Title: Improvements relating to the preparation of alginate material
Inventor: SKELTON LESLIE ZACCHEUS
Filed: 1959-04-20
Abstract: A mixed salt of alginic acid having a controlled solubility in water is obtained by treating calcium alginate with a salt of ethylene diamine tetraacetic acid, the cations of which are solubilizing so that sufficient calcium ions are exchanged for the solubilizing ions to impart a desired degree of solubility.  The solubilizing ions may be alkalimetal such as sodium, or ammonium or magnesium.  In an example, 4,000 grams of calcium alginate gauze is mixed with 6 gallons of industrial methylated spirit and 2 1/3 gallons of water, and 3,000 millilitres of a 30% solution of the disodium salt of ethylene diamine tetra-acetic acid is mixed with 1/3 of a gallon of water and the whole then mixed for 20 minutes.  The gauze is then rinsed in spirit and dried.  Specification 653,341 is referred to.

Filed: 1935-05-09
Abstract: 456,527. Steam superheaters. SUPERHEATER CO., Ltd., Bush House, Aldwych, London, and GASS, E. M., 77, Brownlow Road, Horwich, Lancashire. May 9, 1935, No. 13703. [Class 123 (iii)] [See also Group XXIX] Locomotive regulating valve apparatus of the kind comprising several lift valves opened by cams, fingers or like means on a rockshaft 8 has a further crank or arm 16 carried on the rockshaft within the chamber receiving steam directly from the boiler, this crank 16 being connected to a reciprocable operating rod 18 passing through the steam inlet and the boiler barrel to the driver's cab. Figs. 3, 5 show the invention applied to the header of a superheater. The partly balanced doublebeat valves 5a, 5b control the flow of superheated steam from a chamber 21 to a delivery chamber 22 having a delivery neck 7a at each end. The rockshaft 8, the most part of which is located in the chamber 21, is in two portions, the adjacent ends 8a of which project into a pocket 24 receiving saturated steam from the boiler through a neck 19. The driver's rod 18 passes through this neck and is connected to a crank 16a pinned or otherwise secured to the ends 8a. The parts of the rockshaft passing through partitions 26 between the chamber 21 and the pocket 24 have sealing grooves 27. Bearings 25 for the rockshaft are closed by removable covers 25a. These bearings are fitted with removable liners or the outer ends of the rockshaft are of increased diameter as shown to permit removal of the shaft with its bifurcated fingers 28. The arrangement of the cams or fingers 28 is similar to that described in Specification 296,513, [Class 123 (iii)], and may be such that the valves open simultaneously or in a predetermined order. The pocket 24 which has a removable cover 24a merges with an elongated chamber 20 to the base of which the inlet ends of the superheater elements 23 are bolted. The outlet ends of these elements are likewise connected to the chamber 21. A further form is shown in which one of a series of unbalanced lift valves has a pilot valve seating on it. In this case, both the inlet and outlet ends of the superheater elements are connected to the base of the header, in which is a series of chambers, alternate ones being in communication with chambers 20, 21 respectively. Specification 351,088, [Group XXIX], also is referred to.

Title: Improvements in or relating to data processing circuits
IPC: H03K19/16
Filed: 1957-04-30
Abstract: 847,114. Controlled non-linear inductors. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. April 30, 1957 [May 3, 1956; Sept. 8, 1956], No. 13772/57. Class 40 (9). In a data processing circuit which performs logical operations on binary information represented by the presence or absence of D.C. signals, a transformer 4, Fig. 1, having a core with a rectangular hysteresis characteristic is connected to an A.C. source 3 over one or more branch circuits 1-2, 1<SP>1</SP>-2<SP>1</SP>, each comprising A.C. windings 10, 11 of magnetic cores 14, 15, the magnetisation levels of which are individually determined by D.C. signals in the respective control windings 12, 13, each magnetic core 14, 15 having a saturation current value which is low relative to that of the transformer so that all the cores in a branch circuit must be saturated by their respective control signals for the current from the A.C. source to be of sufficient value to change the remanent state of the transformer core and thereby establish an output in its secondary winding 6. Each branch circuit thus carries out the logical AND operation while the parallel branch circuits form a further logical OR network since full conduction in any branch brings the transformer into an operative condition. The transformer secondary winding may be centre-tapped, as shown in Fig. 2, and associated with rectifiers 16 to provide a full-wave rectified output which is smoothed by a condenser 17, the resultant signal controlling a magnetic core 20 which may be connected in one of the branch circuits such as 1-2. Alternatively the alternating transformer secondary current may directly control a magnetic amplifier 24, Fig. 3, the output of which is derived from an A.C. source 25 and rectified at 26. In a modification, Fig. 4, a complementary output is obtained by including an anti-phase A.C. source 28 in the amplifier control circuit. It is stated that the data processing arrangement forms a logical AND unit if a single branch circuit 1-2 is provided, or a logical OR unit if each of a number of branch circuits comprise but a single core. The output circuit of the transformer may be modified as shown in Fig. 7 by connecting the secondary winding 6 in series with an A.C. source 43 and a rectifier 44. In this case operation is similar to that of a resetting type magnetic amplifier. With small branch currents no flux excursion takes place in the transformer, and a high output current passes through the secondary winding during alternate half-cycles of the A.C. source 43. If, however, all the cores in a branch 1-2 are saturated by control signals, then current in the transformer primary winding 5 is sufficient to cause a reduction of the core flux and so reduce the secondary winding current in the following half-cycle. This output is complementary and in the arrangement shown is applied to three control windings 46, 47, 48 simultaneously.
