Title: A Method of Covering a Substrate with a Bitumous Layer Reinforced with Synthetic Threads, and the Products thus Obtained
Inventor: ZAADNOORDIJK GOTTLIEB LEBRECHT
IPC: D06N5/00
Filed: 1967-03-17
Abstract: 1,184,838. Reinforced bituminous coaling. ALGEMENE KUNSTZIJDE UNIE N.V. 17 March, 1967 [19 March, 1966], No. 12524/67. Heading B2K. [Also in Division El] A substrate is covered with a layer based on bitumen reinforced with threads comprised of synthetic linear polycondensation products, which threads have been subjected to a pretreatment with montan resin to promote adhesion between the threads and the bitumen. The substrate may be a road or a tile. Organic materials such as wood flour and cork flour all organic fillers may be mixed with the bitumen-based material. The term "linear polycondensation products" is stated to mean the polyamides obtained from lactams, from diamines and dicarboxylic acids, and the polyesters prepared from terephthalic acid or the ester-forming derivatives thereof, and glycols e.g. polyethylene terephthalate. The threads may be in the form of fibres which are mixed with the bitumen before forming into the covering layers. The threads may also be used in the form of woven or knitted fabrics or bonded or non-bonded fibre sheets, preferably woven fabrics made of filament yarns. The threads may be mixed with threads of a different material e.g. glass, cotton, or regenerated cellulose. The woven fabrics can be kept under pretension whilst being incorporated into the bitumen. The montan resin may be separated from montan wax by extraction. Montan resin mixtures may also be used. The threads may be impregnated or sprayed with a solution or dispersion of the montan resin before or after processing into woven fabrics. In the examples, (1) a tile made from a mixture of sand, a filler, gravel and a bitumen was coated with an asphalt emulsion. When the emulsion had broken a polyethylene terpehthalate woven fabric charged with montan was clamped on the tile and another layer of asphalt emulsion applied; (2) a tile was treated as in 1) except that the fabric consisted of a polyamide derived from polycaprolactam; (3) to produce a reinforced road surface a foundation layer of gravel, sand, filler and asphalt bitumen was formed on a sub-layer of compacted sand. An adhesive layer of an anionic asphalt emulsion was provided on the foundation layer and over this a fabric as in 1) which was charged with montan resin was unrolled. This fabric was stretched and pinned down and another coating of an asphalt emulsion sprayed onto the fabric. After the asphalt emulsion had broken, two asphalt layers were successively provided and rolled. Another layer of anionic asphalt emulsion was applied and a binder layer consisting of broken stone, sand, filler and asphalt bitumen rolled onto these layers. The binder layer was given an adhesive layer prepared from an asphalt emulsion, and a second fabric identical with the first was attached and covered with asphalt emulsion. After the emulsion had broken a top layer consisting of broken stone, filler, and asphalt bitumen was applied.

Title: An integrated electronic circuit
IPC: H03K19/094
Filed: 1965-03-24
Abstract: 1,098,468. Integrated circuits. SOCIETE SUISSE POUR L'INDUSTRIE HORLOGERE S.A. March 24, 1965 [March 26, 1964], No. 12579/65. Heading H1K. [Also in Division H3] An integrated circuit (Fig. 1) comprising only insulated gate field effect transistors and capacitors is formed at one surface of a P-type silicon wafer by first diffusing donor material through oxide masking formed using photolithographic techniques to form N zones 2, 3, 4 constituting the source and drain regions of transistors T 1 , T 2  T 3 . Aluminium is then deposited over further oxide masking to ohmically contact the zones at 11 and 12 and is selectively removed by photolithographic techniques to leave only areas 5, 6, 7, 9, and 10. These constitute the gate electrodes of the three transistors and electrodes of capacitors C 1 , C 2 , the other electrodes of which are constituted by portions of the N zones 3 and 4. The disposition of the source regions between pairs of drain regions reduces undesired coupling between adjacent transistors. Formation of inversion layers beneath the connections to the gate electrodes may be avoided by providing P + inserts in the silicon at these points.

Title: Circuit arrangement for varying the remanent flux in a magnetisable element
IPC: H03K17/82
Filed: 1961-04-07
Abstract: 909,772. Circuits employing multi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. April 7, 1961 [April 8, 1960], No. 12626/61. Addition to 902,382. Class 40 (9). [Also in Group XL (c)] In an arrangement as described in the parent Specification, in which a storage core has several discrete operating states, and the switching current is permitted to increase to the value at which the rate of change of core flux becomes substantial before its duration and hence the amount of flux change is controlled, the commencement of the substantial flux change is detected by a double differentiating circuit which immediately terminates the switching current. The substantial rate of change of flux commences at the knee of the hysteresis curve, and the immediate termination of switching current is stated to provide a large number of discrete operating states by permitting only a small change of remanent flux. The basic circuit is shown in Fig. 1 in which the winding L1 of a storage core is energized by a current i from a pulse generator 1. When the current reaches a value sufficient to magnetize the core to the knee of the hysteresis loop, it decreases sharply, and the change is detected by a double-differentiating circuit comprising transformers L2 and L3. This operates a switch 2 which switches off the pulse generator prematurely. The same basic circuit is used in Fig. 2 in which the pulse generator comprises a transistor T1 operating with transformer L, capacitor C and discharge resistor Rf as a blocking oscillator, the values of C and Rf determining the pulse recurrence frequency, and the value of C and the inductance of L determining the pulse duration. As previously described, a second differential output is obtained from transformer Tr2 when the knee of the magnetization curve is reached, this output being used to trigger a transistor T2 which in turn prematurely cuts-off the blocking oscillator. A modification is described, Fig. 3 (not shown), in which a transistor multivibrator circuit replaces the blocking oscillator.
