Abstract: 922,798. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. April 19, 1961 [April 27, 1960], No. 14138/61. Drawings to Specification. Class 40 (4). In a system employing remote concentrators wherein communication between a concentrator and the exchange is by means of pulse code modulation on a channel of a time division multiplex system using separate go and return highways as described in Specification 921,384, each line is allotted a free time slot in the multiplex linking its concentrator to the exchange, the information received at the exchange from one party to a call in one time slot being transposed to the time slot allotted to the other party to the call before being retransmitted to the concentrator serving the other party. The transposition is effected by choosing the taps of a tapped delay line which introduce the required delays. A plurality of interconcentrator links are provided in order that connections may be extended to different concentrators in the same time slot.

Abstract: 1,004,490. Solid-state devices. RADIO CORPORATION OF AMERICA. July 30, 1962 [Aug. 16, 19611, No. 29249/62. Heading H1K. A solid state device consists of five superposed layers. One of the outermost layers and the central layer are superconductors and the other outermost layer a non-insulator. The intervening layers are of insulation thin enough to permit hole or electron tunnelling. At the operating temperature the forbidden energy gap of the central layer is lower than that of the outermost superconductor but higher than that of the non-insulator. A typical device in which the non-insulator is also a superconductor, illustrated in Fig. 4, is constructed on a plate 75 of mica, or quartz or borosilicate glass as follows. Contacts 31, 33, 33<SP>1</SP>, 35 are provided by spraying on platinum paint or resinate and heating the plate to 400‹ C. After evaporating tin to form electrode 21, an overlying aluminium oxide layer 20A thick is formed by evaporation of aluminium which is then oxidized in air. A 100A thick layer 23 of lead is evaporated over this and a second aluminium layer formed on top of it as above. Finally a niobium layer 29 is formed by evaporation. During evaporation masking is used to define the area and form of the various layers. Alternative insulating layer materials are silica, deposited by evaporation, and the stearates of barium and chromium which are adsorbed to the underlying layers. The device is operated at liquid helium temperatures at which layers 21, 23, 29 are all superconducting. In an alternative device the layer 21 is a superconductor with a critical temperature below the operating temperature or a non-superconductor such as gold, silver or copper. In operation, the theory of which is discussed, the layers are biased as shown or with the polarities of batteries 39, 45 both reversed an output corresponding to input signal 44 being in either case developed across load 47. The ratio of input to output impedance is determined by the relationship between the forbidden energy gaps in layers 21, 23 and 29 and the relative thickness of the insulating layers.

Abstract: 1,191,156. Packaging liquids. SELFPACK G.m.b.H. 13 July, 1967 [14 Oct., 1966], No. 32360/67. Heading B8C. [Also in Division B5] A welding device for making packages from a tube filled with liquid comprises supports 1, 2 movable along horizontal columns 3, 4. Welding dies 8, 9 mounted on rails 6, 7 are rotatable about axes 5 secured to the supports 1, 2. Springs 12 act so that the surfaces of the dies 8, 9 form an acute angle when in the open position (Fig. 1) and are held by pins 13 in slots 14. The tube 15, which is a strip of plastics or coated paper folded longitudinally at 17 and having a welded seam 16, hangs between the dies 8, 9 and extends downwards into a shaping device, Fig. 5 (not shown). In operation, the supports 1, 2 are moved towards each other and the dies 8, 9 compress the tube 15, forming initially a wedgeshaped cross-section, Fig. 2 (not shown). Further closing causes rotation of the dies about their axes 5 turning the seam 16 away from the centre-line of the tube. This action, and the simultaneous increase in pressure in the liquid due to the compression, removes folds from the parts of the tube to be welded. The shaping device, Fig. 5 (not shown), comprises lateral and lower shaping dies (21), (22), movable in coordination with the welding device above. The lateral shaping dies can contact the tube satisfactorily due to the turning away of the seam 16.

Title: Power capacitor structure and method of assembly
Inventor: HOLTZMAN BARRY LYN
IPC: H01G4/22
Filed: 1981-10-14
Abstract: A power capacitor and method of making it employs the technique of stacking capacitor sections together in an enclosure of which each section includes rolled electrode foils and dielectric layers of which at least one of the electrodes has a rolled edge resulting in a greater thickness in that portion of the section. In order to permit thorough impregnation of the section, the winding tension is deliberately made loose and the initially resulting section is insufficiently tight to retain conductive tabs reliably in contact with the foil electrodes. The stacked sections have, however, between them in the body portion intermediate the rolled edges, one or more sheets of material that compress the body portion and insure reliable pressure contact thereat while not interfering with the impregnation of the fluid throughout the section.

Title: Method and apparatus for the production of mineral wool and mineral wool thereby produced.
Inventor: BATTIGELLI JEAN
IPC: C03B37/04
Filed: 1993-08-13
Abstract: Mineral material, particularly of the basalt type, is fiberized by internal centrifuging in a spinner (1') having a peripheral wall (19) with a multiplicity of orifices through which the melt may emanate into the environment where a hot gas blast attenuates the melt cones emanating from the orifices to fibers. As such mineral material has a high melting point or liquidus temperature, and low viscosity at the liquidus temperature, a high proportion of unfiberized particles is likely to be produced. However, the production of mineral wool with good fiber fineness and largely free of unfiberized particles surprisingly is possible if the cone lengths and the configuration of the gas flows generated around the spinner are such that the majority of the filament forming cones emanating from the spinner orifices intersect the isotherm corresponding to a viscosity of 100 poises, or otherwise reach into a zone cooled down to a temperature corresponding to a viscosity of more than 100 poises. In practice, such a configuration of the gas flows is produced by an outer annular blower (24) complementing the external annular burner (13) which produces jets of cool air so as to bring low-temperature isotherms in close vicinity of the peripheral wall (19) of the spinner (1') where the tips of the cones reach into such cool zone so as to increase the viscosity at the tip of the cones to avoid breakage of the filament to be attenuated.
