Title: Purification of Alkanolamines
IPC: C08J9/28
Filed: 1967-09-18
Abstract: 1,154,924. Purification of alkanolamines. COMMERCIAL SOLVENTS CORP. 18 Sept., 1967 [2 Nov., 1966], No. 42364/67. Heading C2C. A malodorous alkanolamine containing colourproducing impurities and corresponding to the formula wherein R is hydrogen, an alkyl radical of one to three carbon atoms or hydroxymethyl, is purified by contacting an aqueous solution of the said alkanolamine with a resin comprising a cross-linked copolymer of styrene with divinylbenzene, in an amount sufficient to effect a substantial adsorption of the said malodorous colour-producing impurities from the said alkanolamine. Low-boiling impurities may be removed first by heating the alkanolamine to 100‹ C. at atmospheric pressure or to 150‹ C. at 15 mm. Hg pressure. The alkanolamines are used in the preparation of vinyl oxazoline drying oils.

Abstract: 1401475 Rolling; working at specified temperatures NIPPON STEEL CORP 18 Sept 1972 [18 Sept 1971 (3) 3 Dec 1971 5 June 1972] 43113/72 Headings B3A B3M and B3V [Also in Division G3] A method of producing steel plate having a change in thickness 3<SP>1</SP>, Fig. 3, part-way along its length comprises rolling a part of the length of the plate from one end thereof to reduce the thickness of that part with the rolling being effected with a finishing temperature in the range 680‹ to 1050‹ C. The plate may have a step portion on one or both sides. The finishing temperature may be between 680‹ and 850‹ C. when producing a step portion on both sides of the plate and between 850‹ and 1050‹ C. when producing an almost flat rolled surface and a tapered portion or stepped portion on the other rolled surface. In an example, steel of composition: C 0À13%; Si 0À22%; Mn 1À00%; P 0À02%; S 0À010%; and balance Fe was cast into slabs and heated to 1260‹ C. in a furnace. They were then transferred to a roller table where they were descaled and rolled in a four-high rough rolling mill, 2, 2-1. The slabs were finished rolled to the required plate thickness and the roll screw adjusted prior to rolling a differential thickness from the leading edge of the plate. The lower side of the differential thickness steel plate was flattened and the plate was then subjected to a hot leveller to adjust its shape and then cooled on a cooling floor. The rolling of the plates may be controlled using apparatus Fig. 12, comprising a preset device PS for adjusting a roll setting screw, sequence circuits SC1, SC2 for controlling normal or reverse rotation of the roller table of rolling mill R by a signal TFR, and rotation of the mill by a signal MFR and a computer CPU. A button PB provides for switching in operation of the differential thickness rolling and the computer is used to store initial data necessary for the rolling steps so that the unknown, intermediate values of differential thickness and length may be ascertained and controlled. The apparatus also includes a load cell LC, mill rotation meter PLG, thermometer TM and length indicator LD. The dimensions of the finished product are stored numerically.

Title: Telephone switching systems
IPC: H04Q3/00
Filed: 1963-11-07
Abstract: 1,066,589. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Nov. 7, 1963 [Nov. 28, 1962], No. 43947/63. Heading H4K. In an automatic exchange system in which connections to an extension station of a PBX may be set up automatically from a marked controlled central office, the latter is provided with additional translation facilities and an auxiliary switching network for this purpose. An incoming call on trunk 140 of a cross-bar central office is initially directed to an incoming register 137 in which all the digits of the wanted party's number are recorded. A marker 150 then proceeds to connect the trunk to the relevant outlet of the line-link frame in the usual manner. On a call to a particular PBX extension the directory number of the PBX is followed by additional digits which identify the extension. Receipt of a PBX number together with these additional digits causes an auxiliary number group circuit 125 (translation field) to be connected to the marker whereby the latter is " instructed " to connect a free outpulsing (or voice-frequency) sender e.g. 123 via switch 119 or 120 to a free trunk circuit e.g. 106 connected to the PBX. For such a call the normal transmission of ringing current from the incoming trunk end of the switching network is inhibited and is replaced by battery 143 which effectively operates the ring-trip relay. The ringing of the called extension is initiated from the PBX. The incoming trunk circuit 139 responds to the reply of the called party in the usual way in order to initiate metering. If the wanted extension is associated with a PBX e.g. 114 which is connected by a tie-line 147 to one of the PBX's connected directly to the central office, a suitable routing digit is transmitted to the last mentioned PBX before the digits identifying the required extension are transmitted. If the PBX's are connected to the central office by a large number of trunks, the trunks may be divided into groups so that the marker when hunting for a free trunk to a particular PBX can " ignore " those groups in which all the trunks are busy. One or more outpulsing senders are associated with each of these groups and arrangements are described whereby in the event that all the senders associated with a group of trunks are busy, although individual trunks in the group may be free, the group is nonetheless marked busy. These arrangements reduce the holding time of the marker which might otherwise be unduly prolonged due to the extended facilities provided thereby. The PBX's may be of the stepby-step type. The trunks 140 may include waveguides, coaxial or open-wire lines or physical and phantom paths and V.F. or R.F. signalling may be used thereon.
