Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1928-05-31
Abstract: 318,477. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). May 31, 1928. Automatic exchange systems.- In a call-finder system in which each group of lines is divided into sub-groups with individual starting wires 114 - - 118 which enter the group starting chain at different points, the latter is led at intervals over contacts 241 - - 245 of a group busy relay so that when the group 100 is busy, each of the starting wires 114 - - 118 is connected over a limited number of chain contacts to a different point in the starting chain of an overflow group of finders 200 common to two normal groups 100, 110. In the system described, each sub-group occupies two levels of the double-wiper 100-line Strowger - type normal finders. Since with this arrangement simultaneous calls in different sub-groups cause simultaneous hunting by several finders, the sub-group marking potential due to a particular call appears in the vertical strip of only one idle finder, the extension of the marking potentials being looked after by the starting-chain relays 121, 122 &c. Similar arrangements are made in the 200-line overflow finders as regards the lowest 4 terminals of the vertical strips. In this group it will be noticed that the sub-groups reached over the lower part of the bank in the finders on the right are reached from the upper part of those on the left. Circuit details. Sub-group relay 303 energized by the calling line relay 302 marks the calling subgroup in the vertical strip 321 of the nearest idle finder and starts it by energizing its relay 312. 303 over its lower winding also serves another sub-group (not shown). On the response of 312, 313 interacts with the magnet 314 until the sub-group is reached, whereupon 313 is held independently of 314 over wiper 322 in series with 310 which pulls up sluggishly, locks itself and energizes rotary magnet 315 which interacts with 313 until the calling line is encountered by one of the test wipers 318. 308 or 309 then pulls up in series with cut-off relay 304. 308 (which controls wiper selection) if energized energizes 309 which switches the line through, and energizes 311 to connect the cwire 325 to the cut-off relay and transfer the subgroup marking wires and the start wire 324 to the next finder and release 312. 310, 313 also fall back. At the end of the connection the removal of the holding potential from 325 releases 309 which operates the release magnet 316. On the restoration of the off-normal springs 326, 308 and 311 are disconnected. When all the busy relays 311 are operated, the relapse of normally energized relays 402, 403 energizes 400 which controls the contacts 241 - - 245 (Fig. 2) to extend the starting circuits to the overflow group.

Abstract: 944,085. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 30, 1962 [May 12, 1961], No. 16384/62. Heading B6F.  The latches 3 . . . 7 controlling the movement of the typehead 1 as described in Specification 873,920 are actuated by electromagnets, supplied with a pulse code for each character, instead of by a keyboard and, if an erroneous code is fed, the corresponding character is printed in red and the machine stopped. Error detecting.-An additional latch 42 having no effect on the typehead is provided. Each latch is associated with a changeover switch and actuates it if its corresponding electromagnet has not been energized. If the character be represented by an even number of pulses, an additional pulse is supplied to the magnet of latch 42 to give an odd number; if the character be represented by an odd number, no pulse is supplied to the magnet of latch 42. Hence, if there be an error, an even number of pulses is supplied. The contacts of the change-over switches are so interconnected that, if this occurs, a relay stops the power source or interrupts the pulse transmission and energizes an electromagnet 91 controlling the ribbon shaft to print the last character in red. Ribbon shift (Figs. 5 and 6).-Ribbon guides 96 are mounted by a parallel linkage 92, 94 on the type-head carriage the forward ends of links 92, 94 being joined by rods 93, 95 which are pivotally mounted. Each print action rotates once a shaft 99 carrying a cam 100 acting on a follower 101 pivoted to the carriage at 102 so that the follower is pivoted clockwise about 102 once per cycle. An adjustable rod 104 supports one link 92 and rests in a slot 103 in the follower so that it lifts the ribbon guides once per cycle from an inspection position to a black print position. An arm 111 fixed to the rod 93 has a pin 110 engaging a slot in a latch plate 106 pivoted to the follower. Normally, as the follower oscillates, pin 110 idles in the vertical part 109 of the slot.

Title: Separation of primary and secondary alkyl halides
IPC: C11D1/75
Filed: 1965-04-20
Abstract: Detergent compositions contain one or more amine oxides obtained by oxidizing amines formed by reacting a mixture of primary and secondary alkyl halides with an aliphatic secondary amine (Division C2).  The composition may be in the form of a solution in water or an alcohol or in the form of a powder mixed with sodium sulphate.ALSO:Primary and secondary alkyl halides are separated by reacting a mixture containing both with an aliphatic secondary amine to convert at least a substantial proportion of the primary halide into a tertiary amine and/or a hydro halide salt thereof which is then separated from the mixture of the non-converted propor tion of the primary alkyl halide and non verted secondary alkyl halide. The starting mixture may be a mixture of chlorides obtained by substitutive chlorination of alkanes or mix tures of alkanes. When this mixture is sub jected to the above process the remaining unconverted secondary alkyl chlorides may be dehydrochlorinated to form olefins and any chlorides which remain unconverted may be subjected to the above separation process and/or recycled to the dehydrochlorination stage. The tertiary amines produced in the separation process may be oxidized to the corresponding amine oxides.
