Title: Process for the impregnation of fibrous material for use in the production of thermosetting synthetic resin laminates
IPC: D21H17/48
Filed: 1954-06-01
Abstract: 760,751. Thermosetting synthetic resin laminates. UNION CARBIDE & CARBON CORPORATION. June 1, 1954 [June 19, 1953], No. 16229/54. Class 140. Resin -impregnated fibrous sheet material, from which laminates may be made by hotpressing superposed layers, is prepared by impregnating the sheet material with an aqueous solution of hexamethylene tetramine and with molten novolac resin applied successively in either order. The fibrous sheet material may be cellulosic or asbestos paper, woven cotton or linen fabrics, fabrics or batting of glass fibres, nylon, glycol terephthalate polyester fibres, polytetrafluoroethylene fibres, or plywood. The novolac resin may be prepared from a monohydric phenol and an aliphatic ketone or aldehyde. The crystalline diphenylols and triphenylols may be used as such or in admixture with higher molecular weight resinous condensates. Novolao mixtures containing under 65 per cent by weight of diphenylols and triphenylols cannot be used as first impregnant since they form a continuous resinous coating on the fibres. An unreacted monohydric phenol such as phenol, cresol, or para tertiary butyl phenol may be added to the novolac to increase its fluidity.

Title: Improvements in and connected with copper-base alloys containing zinc
IPC: C22C9/04
Filed: 1942-11-18
Abstract: 568,665. Alloys. STONE & CO., Ltd., J., CALLIS, G. T., and MURPHY, A. J. Nov. 18, 1942, Nos. 16281/42 and 870/43. [Class 82 (i)] The detrimental effects due to the presence of arsenic or antimony, introduced intentionally or present as a contamination, in copper base alloys containing zinc as the principal alloying element and constituted of the beta or the alpha+beta phase, are avoided by an addition of nickel or cobalt which, though small in relation to the mass of metal treated, is relatively large in comparison with the amount of arsenic or antimony present in the alloy. In cases where 0.1-1.0 per cent of arsenic or 0.1-0.3 per cent of antimony is added to manganese and other bronzes to prevent dezincification, deterioration of the mechanical properties of the bronzes is avoided or minimized by the addition of 0.4-5.0 per cent of nickel or cobalt. In brasses made from remelted scrap containing arsenic or antimony, the deleterious effect of the presence of these contaminations is avoided or minimised by the addition of up to 5 per cent of nickel or cobalt. As an example, a manganese bronze containing copper 61 per cent, tin 1 per cent, aluminium 0.25 per cent, manganese 1.0 per cent, iron 1 per cent and the remainder zinc, may receive additions of arsenic 0.5 per cent and nickel or cobalt 2 per cent.

Title: Coding Equipment for P.C.M. Systems
Inventor: REEVES ALEC HARLEY
IPC: H03M1/38
Filed: 1966-04-18
Abstract: 1,158,842. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 14 April, 1967 [18 April, 1966], No. 16816/66. Heading G4H. In an analogue-to-digital converter there is provision for correcting variations in the coding elements which includes means for sampling the error signal after each switching step of the coding elements and integrating it over a number of cycles to form feedback signals to correct the operation of the code elements. The converter is of the type described in Specification 1,046,792 in which the analogue input is applied to the coding elements together with a damped oscillation and the coding elements respond sequentially. As the input value rises, the "1" element switches first at a threshold level q, Fig. 2, subtracting a value q so that the input to the coding elements reverts to zero instantaneously, before increasing again. When it next reaches value q the "2" element switches subtracting a value of 2q, the 1 element reverts so that the input again becomes zero before climbing again to q. At this point the "1" element switches again. The process repeats until the input is balanced, the pattern of "1's" and "0's" in the coding elements representing the input value. Fig. 2 shows the conditions when the elements are working properly. Errors may be introduced due to incorrect threshold response of an element. This is shown in Fig. 3A, where the "1" element is switching at too low a threshold level. The other error is due to the weighting of the element being too large or too small. In Fig. 3B, the "1" element has too small a weighting so that the input signal does not revert to zero before starting the next climb. If these defects are in the "2" element the operation is as in Figs. 3C and 3D and, if in the "4" element, as in Figs. 3E and 3F. The correction circuit shifts the datum from zero to ¢q so that the curve between each digital step should have equal positive and negative areas and, when integrated, should be zero. The correction signals are provided by having gates responding to the digital combinations by which the selected interval is identified. For example, for the threshold error of the "4" element, Fig. 3E, the input is sample for the period before the "4" element switches i.e. from condition 011 to condition 100. The input is integrated over a large number of conversions and if the result signal is other than zero it is fed back to the 4 element to alter its threshold response. For the weight error, the input is sampled for the period after the switching of the "4" element i.e. from 100 to 101 and this again is integrated to obtain a feed-back correction signal. As described the correction signal is applied to the heater of a thermistor in series with the tuned diode which forms the coding element. There is a similar thermistor in parallel with the tunnel diode (Fig. 10, not shown).

Title: Improvements in and relating to discharge devices, resistance materials, and to processes of preparing the same
IPC: H01C7/118
Filed: 1928-06-13
Abstract: 292,110. British Thomson-Houston Co., Ltd., (Assignees of McEachron, K. B.). June 13, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Protective arrangements.-A crystalline resistance material, especially suitable for lightning- arresters and like safety devices, has a specific resistance inversely proportional to some power of the current traversing it; the resistance may be nearly inversely proportional to the current, so that practically no current passes until a certain voltage is reached, but above this voltage the material will carry a very large current. Such a material may be made by mixing carborundum with a binder such as clay, cement, lead borate or glass, drying, heating and firing. The characteristics of the material can be regulated by altering the proportion of free carbon in the carborundum, which can be effected by oxidizing the carbon in free oxygen or by oxidizing agents such as potassium chlorate, nitric acid, or nitric and hydrofluoric acids, and adding carbon in the form of graphite or lampblack to the required amount. The proportion of free silicon can be adjusted similarly. Tellurium, tungsten, cobalt, nickel, molybdenum, iron, silicon, &c. may be added to increase the conductivity and zincite, galena and psilomelane may be used either instead of or in addition to the carborundum. Lightning arresters may be made of one or more blocks of the material, which may be coated with metal, with or without a spark gap. Insulating supports of the material for electric conductors serve also as safety devices for passing excessive voltages.
