Patent EG-19093-A (EG)
Title: Separable fastening device, method of making the same and method of releasably fastening articles.
Inventor: MELAUGHLIN CAROL A
IPC: B65D33/24
Filed: 1990-12-27
Granted: 1994-10-30
Abstract: A separable fastening device is provided for releasably fastening a first surface to a second surface. The separable fastening device comprises a first fastening element of high static vinyl material which is attached to the first surface, and a second fastening element of high static vinyl attached to the second surface. When the first fastening element and the second fastening element are placed against each other in a face-to-face relationship, the attractive forces between the first and second fastening elements form a separable bond between the first and second surfaces.

Abstract: 845,077. Induction heating. FORGINGS & PRESSWORK Ltd. Jan. 2, 1959, No. 147/59. Class 39(3). [Also in Group XXXV] An induction heating coil for heating work pieces of iron steel or other alloys of iron forms part of a circuit arranged to be supplied with A.C. at mains voltage and frequency, the circuit also including an adjustable transformer operable to reduce the voltage across the induction coil to a maximum of substantially 20 volts. As shown, a copper tubing heating coil 1 is connected to the adjustable secondary winding of a step-down transformer 9 which is energised by the delta-connected secondarywinding of a three-phase transformer 6. A heating coil current of 3000 to 8000 amperes at 10 to 15 volts is obtained when a 400 volt, 50 c.p.s. supply is used. The coil is liquid, e.g. water, cooled and is interchangeable with other coils for workpieces of different shapes and sizes.

Abstract: 1490951 Moulding protective layer on electrical components SIEMENS AG 5 Jan 1976 [31 Jan 1975] 00152/76 Heading B5A An electrical component, e.g. a relay 1, having a base 1b with connection pins 2 and a dust cap 1a forming an enclosure with the base, has a protective layer 5 heat shrunk on to the base and extending to embrace the cap with the pins projecting through holes 5b in the layer 5, an adhesive 6 being used between the layer 5 and the cap and base which melts during heat shrinking. An injection moulded protective layer 5 of cross-linked polyolefin which has been stretched a larger amount around the sides 5c than around the holes 5b is given a coating of adhesive 6 which covers the holes. The layer 5 may have more holes than there are pins 2 so that one standard shape can be used for different pin arrangements. The holes where there are no pins remain sealed with adhesive. Five quartz glass jaws 7 press the layer 5 on to the component 1, the lowermost 7a having holes 9 to accommodate the pins 2. The layer 5 is coloured black and is heated by infra-red radiation passing through the jaws 7 from sources 8. Alternatively heated jaws or hot air may be used.

Title: Improvements in abrasion resistant wire enamels
IPC: H01B3/44
Filed: 1950-01-04
Abstract: A wire enamel comprises a heat-hardening synthetic resin, a polyvinyl acetal and from 0.09 to 0.5 per cent of polyethylene based on the other two resins, preferably dissolved in a hydrocarbon liquid.  The preferred heat-hardening resin is phenol-formaldehyde but melamine-, urea- and substituted phenol-formaldehyde resins may be used. Polyvinyl formal is the preferred acetal resin.  The ethylene polymer is preferably the homopolymer having a molecular weight between about 9000 and 10,000, but modified polymers prepared in the presence of chain-terminating agents such as dioxolane, cyclohexane, methyl propionate, propionic anhydride, diethyl ether, methanol and hydrogen, may be used.  In the examples, the polyethylene is added in the form of a dispersion containing also small amounts of the other resins together with some of the petroleum hydrocarbon solvent and cresylic acid.  Other ingredients include furfural and high-boiling tar acids.  Curing at 585 DEG  F. produces an enamel having high scrape abrasion resistance.  Pigments, e.g. phthalocyanine green, may be added to the mix.  Specifications 580,182, 581,899, 587,586, 593,313, and 605,848, and U.S.A. Specifications 2,153,353 and 2,307,588 are referred to.

Title: Improvements in or relating to means for translating electrical variations into light variations
IPC: H04N5/66
Filed: 1927-01-08
Abstract: 264,176. Telefunken Ges. f³r Drahtlose Telegraphie. Jan. 9, 1926, [Convention date]. Photographic recorders; copying-telegraphs.- Light interference effects are utilized in arrangements for relaying or recording electric currents for picture telegraphy, high-speed telegraphy, or sound recording. In one arrangement, Fig. 1, current supplied to windings W<1>, W<2> controls electromagnetically movement of a diaphragm M carrying at each side a mirror surface Sp receiving light from a source L. Light from the source is incident obliquely on a glass plate J, one portion being reflected at the partially-silvered front face of the plate and another being refracted and reflected from the rear face. The directly reflected ray and the refracted ray, which are arranged to be of substantially equal intensity, are reflected by mirrors 2, 1 respectively on to the opposed mirror surfaces Sp, and after further reflection by mirrors 4, 3 respectively are focused by a lens O to a point F on a stationary or moving photographic surface or a light-sensitive cell S where they interfere to produce a record on the surface or to vary the current in the circuit of the cell. Alternatively, when using non- parallel rays, the interference bands produced are projected on a diaphragm provided with alternately opaque and transparent strips, and therays passing this diaphragm are focused on the sensitive surface or cell S. Fig. 2 shows another arrangement. A parallel beam from a, source 1 and lens 2 is incident obliquely on a glass plate 3 at the front face of which it is refracted with negligible reflection. The refracted beam is reflected partly at the rear face of the plate, and partly by a mirror surface 8 carried by a diaphragm 9 controlled by an electromagnet 10. An initial tension is imparted to the diaphragm as by a direct current supplied to the electromagnet coil or by polarized cores. The two reflected portions, which are arranged to be of substantially equal intensity, are focused by a lens 5 to a point 7 on a sensitive surface 6. The movements of the diaphragm may in all cases be effected through a moving-coil, nr electrostatically, or thermally, i.e. by bending of the diaphragm by expansion of a wire heated bv the controlling current. Specification 256,611 is referred to.

Title: Ternary logic circuits
IPC: H03K19/082
Filed: 1972-01-07
Abstract: 1367205 Semi-conductor logic circuits INTERNATIONAL BUSINESS MACHINES CORP 7 Jan 1972 [5 Feb 1971] 766/72 Heading H3T A ternary logic circuit consists of current switches T1, T2 and T3, T4 having respective current sources T5, R2 and R1, the interconnections of the switches and the current source magnitudes determining the ternary logic function performed. The three level output Vo then represents a corresponding one of various ternary logic functions of a three level logic input signal Vi. For example, the circuit of Fig. 4 produces a so-called "interchanger 0" function, wherein the output Vo is 0 when the input Vi is 0, but the other two states of the input (1, 2) appear reversed at the output. To achieve this, the current source T5, R1 is made to produce two units of current and the source R2 only 1 unit. When Vi is "0", the lowest value, T1 is off and consequently T3 is off, so that T2, T4 are on. The base of T6 in an emitter follower output stage T6, T7 is therefore held at a low level due to two units of current in R3 flowing to T2, and this causes Vo to be at "0" level. If Vi is "1", an intermediate level, T1 goes on but still not T3; therefore T2 and T3 are both off and the base of T6 goes to +V to give a "2" output at Vo. If Vi is "2", the highest level, T1 and T3 are on, and T3 supplies one unit of current through R3. T6 base is thus at an intermediate level and Vo is "1". To provide an "interchanger 1" function, where Vo is "1" when Vi is "1", but the other two logic levels are reversed, the load resistor R3 is connected to the collectors of T1 and T3 (R1, Fig. 6, not shown) and the current sources (T5, R2, and R3) both supply one unit. A circuit providing the "interchanger 2" function (Fig. 5, not shown) includes a third emitter-coupled pair (T9, T10) with a separate collector load (R5) driving a separate emitter follower (T7) whose output is combined (in T8) with that of the first emitter follower (T6). Another modification of Fig. 4 (Fig. 7, not shown) provides a so-called "clockwise rotor" function wherein the output Vo is one level displaced upwards from the input Vi, and an "anticlockwise rotor" function is provided (Fig. 8, not shown) by a modification of the Fig. 5 circuit.
