Title: An automatic telecommunication exchange
IPC: H04Q3/00
Filed: 1966-09-23
Abstract: 1,120,537. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 23 Sept., 1966 [30 Sept., 1965], No. 42495/66. Heading H4K. In a multistage reed relay switching network through which paths are selected by means of a route simulation network utilizing accepting/ catching potential techniques, a particular path may be chosen for test purposes by, in effect, artificially busying all nodes except those pertaining to the wanted path. The nodes AV (also known as marking centres or offering signal regenerators) corresponding to matrices m1-m5 and nl-n3 in stages KSm and KSn respectively of the network include blocking contacts wm1-wm5 and wn1-wn3 in their " outlets " for effecting the " busying " of unwanted nodes during testing. Two embodiments, one involving relays (Fig. 2, not shown), and the other involving transistors (Fig. 3, not shown), are described by which the selective operation of contacts wn and wm may be effected The network may comprise a plurality of parallel sections each of which utilizes the same common circuitry for operation of its blocking contacts, the particular section under test being chosen by selective operation of a section relay (SU, Fig. 2) or section transistor (Tr1, Fig. 3).

Title: Process for the manufacture of foamed gypsum
IPC: C04B24/00
Filed: 1976-10-13
Abstract: 1498614 Polyurethane-gypsum foam HOECHST AG 13 Oct 1976 [15 Oct 1975] 42521/76 Heading C3R A process for the manufacture of foamed gypsum and constructional elements composed thereof comprises mixing gypsum with water in the presence of additives for liquefying the gypsum, regulating the foaming time and regulating the setting time of the foam; dispersing in this mixture from 1 to 30% by weight based on the weight of the gypsum of one or more polyurethane prepolymers prepared by reacting excess polyisocyanate with one or more polyesters and/or polyethers containing -OH groups; pouring the dispersion into a mould and allowing it to foam and to set after foaming has terminated to form a constructional member, e.g. a ceiling or wall board. Suitable liquefying additives are melamine resins, e.g. sulphonic acid modified melamine resins which may be used in amounts of from 0À1 to 3% by weight based on the weight of gypsum and a suitable additive for regulating the setting time, i.e. for preventing the gypsum hardening before the completion of foaming, is carboxymethyl cellulose used in an amount of from 0À1 to 2% by weight based on the weight of gypsum. To allow time for mixing and filling the dispersion into a mould the foaming reaction may be delayed, e.g. by 5 minutes, by using an additive consisting of a catalyst, e.g. dibutyl tin laurate absorbed on zeolite powder to diminish the activity of the catalyst. This additive may be used in amounts of from 0À1 to 2% by weight based on the weight of the prepolymer. Additional additives for example silicon surfactants as foam stabilizers and volatile fluorocarbons as blowing agents may be used in the process. Sandwich constructional members may be produced by allowing the prepolymer/gypsum dispersion, which may additionally contain a bonding agent, e.g. a redispersible polyvinyl alcohol, to foam between cover sheets, e.g. of hard board or chip board to which the foamed gypsum adheres.

Abstract: 1,158,337. Polymer blends. BORG-WARNER CORP. 27 Sept., 1966 [11 Oct., 1965], No. 43049/66. Heading C3P. A resinous composition comprises 60 to 85% by weight of a homopolymer of a monovinyl aromatic hydrocarbon or a copolymer of two or more such monomers, 5 to 15% of a resinous styrene copolymer containing a major proportion of styrene units and 10 to 25% of a rubber selected from conjugated diene homopolymers and copolymer of a conjugated diene with a vinyl aromatic hydrocarbon, said composition containing 0À1 to 0À5 parts by weight of an organic peroxide per 100 parts of polymer. The monovinyl aromatic hydrocarbon resin is derived from e.g. styrene, vinyl toluene, vinyl xylene, ethylvinyl benzene, isopropyl styrene or ethylvinyl toluene. The rubber may be a butadiene-styrene rubber or polybutadiene. Preferred peroxides are dicumyl peroxide, diacyl and diaroyl peroxides, cumyl hydroperoxide, α,α-dimethyl-p-butylbenzyl hydroperoxide, α,α- dimethyl-p-diisopropylbenzyl hydroperoxide and α.α-dimethyl-p-isopropylchlorobenzyl hydroperoxide. In examples blends of polystyrene, a styrene-butadiene resin, polybutadiene, dicumyl peroxide, an antioxidant, MgO and an antistatic agent are prepared.

Title: Logical decision tree desing
IPC: G06K9/62
Filed: 1971-09-16
Abstract: 1327325 Character recognition systems; data processing systems INTERNATIONAL BUSINESS MACHINES CORP 16 Sept 1971 [7 Oct 1970] 43155/71 Headings G4A and G4R A descision logic tree for use in pattern recognition is designed by a data processor in dependence on the states (black/white) of manually selected points in a stored pattern. A pattern, e.g. representing an alpha-numeric character, is read from a store 102, Fig. 1, when called for by touching with a light pen 105 an appropriate word on the list 140 on display 104. The pattern is stored in a video buffer and may be displayed over matrix 150. When the pen touches any of the dots of the matrix the state of the pattern at that point is displayed (O for white, X for black) and a section of the decision tree is automatically designed in the processor. When it is believed that sufficient dots to identify the character have been touched the operator touches the pen to that one of the characters in list 130 that he thinks corresponds to the pattern. This character is automatically compared with the correct identification, originally stored in 102 with the pattern. If the character is correct it terminates the currently designed limb of the tree. If the comparison shows the character is not correct an alarm is sounded and further points are selected to extend the limb in an attempt to reach the correct termination. Instead of extending the limb it may be cancelled, or the last node of the limb or the whole tree may be cancelled. Alternatively the limb may be forced to terminate in the selected character, Another pattern is now read from store 102 to the video buffer. All the dots tested in the previous pattern or patterns are displayed, showing the states at the corresponding points of the current pattern. The logic design cycle is repeated, building up a new limb. When the tree has been completed it may be printed out at 103. In order to aid the operator's choice of dots characters may be displayed on the matrix, e.g. as a vertical stripe image. These characters do not effect the previously touched dots, which still indicate the state of the points of the pattern currently in the video buffer. The pattern in the buffer may be shifted vertically or horizontally to place it correctly on the matrix. The logic tree may be shifted, skewed, or rotated relative to the pattern.

The insulating comb 4 is placed above the strips 5<SP>1</SP> and a die 11 descends to fold the strip 51 about the comb 4, the member 10 which supports the comb also descending. A die (18) (Fig. 5, not shown) then moves to the left to bring the free ends of the strips together and a die (17) (Fig. 6, not shown) moves to the right to bend the free ends of the strips through a right angle. The turned-up end of the strip 5<SP>1</SP>a is then bent over the other end of the strip using dies (14) and (19) (Figs. 7, 8, not shown). The support member 10 is raised and the completed plug-in connection is removed from the machine.
