IPC: H04Q3/00
Abstract: 263,467. Automatic Telephone Manufacturing Co., Ltd., (Automatic Electric Co.). Aug. 25, 1925. Drawings to Specification. Automatic and semi-automatic exchange systems; metering.-In a system in which impulsing current is fed forward towards the called party, the impulses are sent by intermittently reversing the direction of current over an outgoing trunk. The invention is described as applied to a system which is identical with that described in Specification 263,210. Two forms of impulse repeaters are described which are located at the outgoing end of a two-wire trunk and effect the impulsing current reversals thereover. In the first modification, battery and earth are normally fed forward through an impedance consisting of the windings of a back-bridge relay, and impulses are transmitted by directly connecting to the outgoing conductors an additional source of current so as to reverse the current over them, whereas in the second modification the connections between the windings of the back-bridge relay and the outgoing conductors are actually reversed at each impulse. The repeaters are completely cut out when the setting operation is finished. The line relay of the selector at the incoming end of the trunk is a polarized one having both its windings normally bridged across the trunk. Directly the trunk is seized, the line relay responds and prepares the incoming selector, in this condition one of its windings only being bridged across the trunk, and the other polarizing winding being energized in a local circuit, in order that it may respond to subsequent current reversals over the incoming trunk. After the completion of impulse sending both windings of the line relay are again bridged across the trunk in order that it may release in response to cessation of current to give the calling party control of release. Specifications 193,694, 194,580. 226,154, and 246,550 are referred to.

Abstract: 1,220,266. Moulding composition. MONSANTO CO. 5 June, 1968 [5 Sept., 1967], No. 26750/68. Heading C3B. A moulding composition in grain form is made by stirring into an aqueous slurry of fibres a thermosetting resin and a curing agent therefor at a temperature at which the resin is liquid, continuing stirring until the resin reaches the "B"-stage, rapidly cooling, removing the water, and drying the residue. A predominant number of the grains comprise parallel reinforcing fibres bonded by thermosettable resin to form an integral unit and a film of resin is bonded to and completely envelopes the unit. The fibres are of length 30 Ám-1 inch, with length/diameter ratio of from 20 to 1000. The resin may be an "A"-stage epoxy, polyester, phenolic, amine, amide, or urethane resin; epoxy resin is specified in all the examples. The fibres may be of glass, B, SiC, silicon nitride, C, graphite, Nb, Ta, Hf, W, Mo, bronze, Cu, Pb, Be, Ag, stainless steel, SiO 2 , Al 2 O 3 , sapphire, ZrO 2 , TiO 2 , asbestos, hemp, bamboo, Al 2 O 3 /SiO 2 , potassium titanate, nylon, polyacrylonitrile, polypropylene, or polyester, or mixtures thereof. The fibre slurry may be formed in water containing a surfactant, preferably cationic or non-ionic. Also present may be 0-40% by volume, based on fibre+ filler, of fine filler as a collimating aid, e.g. clay, talcum, lampblack, rutile, SiO 2 , SiC, or crushed glass wool, asbestos, or fibrous clay; or electrical conductors or insulators, thermal insulators, or radiation shielding materials, e.g. Pb powder, may be used. The mixing may be performed by separately warming slurry and resin, e.g. to 50-100‹ C., and stirring the resin into the slurry. The curing agent may be added to the mixture or to the resin just before mixing with the slurry. A coupling agent may be added to the slurry before the resin and curing agent. The dried granules may be compression or transfer moulded. They may first be extruded through a constricted channel to obtain a pre-preg strand having oriented fibres; this extrusion is conducted at a temperature low enough to prevent conversion to the C-stage; e.g. 100-150‹ C.

Title: A method for separation of press water obtained from cooking of marine animals
IPC: C11B1/00
Filed: 1954-09-16
Abstract: <PICT:0752052/III/1> In the continuous separation of oil from press water obtained from cooking of marine animals, particularly herring and whale, glue-water being discharged from an overflow provided in the separating plant, the glue-water taken from the separation is subjected to a breaking treatment for the oil foam and tissue cells and the glue-water thus treated is returned to the inlet of the separating plant.  A centrifugal separator or a gravity separator may be used, each provided with an oil overflow, a glue-water overflow and a sludge outlet.  In a suitable plant, the press water from a cooking operation is pumped through a pipe 6 to a heater 7 where it is heated to separation temperature and from thence through a pipe 8 to a nozzle centrifuge 9.  The oil is discharged from pipe 10, sludge through pipe 11, and the glue-water from its overflow passes through a pipe 12 to a container 14 from which it is pumped through a pipe 16 and a heater 17 into an autoclave 18 for the breaking treatment. From the latter the hot glue-water under pressure flows through a pipe 19 and a pressure regulator 20 to the pipe 6 where it mixes with fresh press water and returns to the inlet of the centrifuge 9. Preferably the oil contained in the glue-water is concentrated to that glue-water which is taken from the separator over the gluewater overflow by carrying out the separation in such a way that only a smaller part of the glue-water is allowed to discharge over its overflow.  In a modification, wherein the oil discharged from the separator is separated, the first separation is carried out in such a way that the oil contains a large quantity of glue-water which is separated from the oil by a second separation and then subjected to the breaking treatment as before.  The breaking treatment may comprise heating the gluewater to above 100 DEG C. under super-atmospheric pressure or by the known addition of various agents thereto, such as alcohols, acid electrolytes, e.g. sulphuric acid or hydrochloric acid, and alkali, e.g. caustic soda.
