Filed: 1960-12-22
Abstract: 909,932. Polymer/rubber compositions. SHELL RESEARCH Ltd. Dec. 22, 1960, No. 44068/60. Classes 2(6) and 70 The impact strength of a polymer of a monovinyl-aromatic compound is improved by blending and heat-treating in admixture with a natural or synthetic rubber and an inert filler on which is adsorbed an organic free-radical polymerization initiator which effects crosslinking of the rubber. Polymers specified are those of styrene, α-methyl styrene, vinyl toluene and p-chlorostyrene, and the synthetic rubber may be a copolymer of butadiene with styrene, acrylonitrile or isobutylene, butyl rubber, polyisobutylene, polybutadiene, polyisoprene, or an ethylene/propylene copolymer. Fillers disclosed are calcium carbonate, magnesium carbonate, calcium phosphate, calcium sulphate, barium sulphate, titanium dioxide, talc, silica and metal alumina-silicates; the initiator is an organic peroxide or hydroperoxide, a perester or an azo compound and, preferably, is dicumyl peroxide or di-t-but peroxide. Optional ingredients are stabilizers, lubricants such as stearates, pigments and antioxidants, e.g. butylated phenol. The products may be formed into shaped articles.

Title: Improvements in or relating to adhesive mixtures
Inventor: DOARKS PETER FRANKLIN
IPC: C09J103/02
Filed: 1965-10-19
Abstract: An adhesive consists essentially of maize, wheat or potato starch which has been gelatinized; an enzyme inactivated, heat-treated wheat flour as described in Specification 1,085,562; an alkali; and water, all substantially in the proportions required for use in the Stein-Hall process, and an additional chemical substance capable of raising the gelatinization temperature of the treated wheat flour to 65 DEG  C. or over. Specified additional substances are sodium sulphate, chloride, formate or fluoride or a mixture thereof.  In comparative examples sodium acetate, citrate, thiosulphate, tartrate, dihydrogen phosphate, hexametaphosphate, borate and potassium ferrocyanide also feature, in admixture with the wheat flour.  Sodium hydroxide is a specified base. In manufacture, the potato, wheat or maize starch may be gelatinized in hot water and this mixture added to an aqueous mixture of the heat-treated starch containing the additional substances; alternatively the maize, potato or wheat starch is pregelatinized and all three components are mixed together. The adhesive is useful in making corrugated cardboard.

Title: Delay Line Pulse Generator Circuit.
IPC: H03K5/15
Filed: 1966-10-05
Abstract: 1,159,697. Pulse generators. WESTING- HOUSE ELECTRIC CORP. 5 Oct., 1966 [29 Oct., 1965], No. 44465/66. Heading H3T. A pulse generator comprises a delay line with a plurality of taps, means for applying a logic "1" signal to the input and means coupled to one of the taps to clamp the input to the line to a logic "0" after the signal has reached that tap, thereby to produce a pulse whose duration depends on the position of the tap. In Fig. 1 a start pulse is applied through an OR gate 30, bi-stable circuit 32 and amplifier 22 to the input of a delay line 12. Taps 18-1, 18-2, 18-3 feed back the signal levels through amplifiers 38, OR gate 48 and inverter 50 to clamp the input to the line to a zero level from the time when the leading edge reaches 18-1 to when the trailing edge clears 18-3. Spurious pulses at 34 or picked up by the circuit cannot thus cause false triggering. The output of the line is backcoupled through amplifier 24 and AND gate 28 to the input, so that the circuit is free-running as long as the second input 52 to the AND gate is energized. Outputs can be taken from 16, 40, 42, 44 for use, e.g. in computers. The tap positions are chosen so that the pulses overlap at the various tap points to keep the OR gate 48 continuously operated while a pulse is in the line. Any change in line parameters due to temperature changes will affect all sections proportionately and will not upset this overlap. If a spurious pulse should be present on the line a new pulse cannot be entered until this has cleared, as the input is clamped by the feedback through the OR gate 48. Each amplifier 38 preferably comprises an integrated NAND circuit (Figs. 2-4, not shown) with its second section used either (a) for additional logic inputs, (b) for the next amplifier (e.g. 38-2), or (c) in parallel with the first.

Title: Improvements in or relating to storage of binary information
IPC: G11C11/06
Filed: 1961-12-14
Abstract: 923,621. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 14, 1961 [Dec. 19, 1960], No. 44805/61. Class 40 (9). A magnetic storage core is read out non- destructively by applying an interrogating field in an " 0 " driving sense and a biasing field in the opposite sense, the interrogating field having a magnitude which exceeds the maximum coercivity of the core and a duration insufficient to switch the core, and the biasing field having a lesser magnitude and longer duration such that after interrogation of the core, if in a " 1 " state, it establishes a steady value of core flux in the " 1 " sense which is less than the saturation remanent value. As described, the non-destructive read-out operation is applied to a core matrix, Fig. 1, which may comprise thin magnetic films, the matrix storage cores 10 being associated with row and column windings X1-X4, W1-W4, a common bias winding 18 and row sense windings S1-S4. In one arrangement, Fig. 2, the cores are continuously biased by a negative field of value NIB, and during the writing operation are first brought to the " 1 " state by a negative field 28 produced by current in a selected word line W1-W4. Selected cores in the switched column are then brought to the " 0 " state by coincident row and column pulses 30, each producing positive fields of value NI 2 . Non- destructive read-out is effected by a short duration pulse 34 of value MI B  in the word line. This pulse has no effects on the remanent state of the " 0 " cores, but cores in the "1 " state have their magnetic field reduced so that under the influence of the bias a new stable state of "1<SP>1</SP>" is obtained on a minor hysteresis loop 24. In an alternative arrangement, Fig. 3, the cores are switched by the normal coincident current selection method. A word line W1-W4 is then energized by a short duration pulse 36, and after this pulse terminates a bias pulse 38 is applied to winding 18. The action of the bias pulse on a core initially in state " 1 " is to bring the flux to a remanent value 1<SP>11</SP> on a minor hysteresis loop 24.

After demodulation (conversion to D.C. values) these errors are changed, in azimuth resolver 19, to angular errors in the orthogonal elevation and cross-elevation planes of the antenna, resolver 19 being referenced to the azimuth axis of the antenna. After passing through loop compensation circuits 23, 24 to damp oscillations, the angular error signals are applied to a further resolver 25, that is also referenced to antenna azimuth axis. Damping may also be provided according to the velocity of the rotating platform.
