Title: Process for producing aldehydes
IPC: C07C27/22
Filed: 1946-08-07
Abstract: Aliphatic or cycloaliphatic aldehydes are produced by reacting hydrogen, carbon monoxide, and an olefine, a cyclo-olefine, an olefinic carboxylic acid in which the olefinic linkage is not immediately adjacent to the carboxyl group, or an ester of such an acid at a temperature of at least 80 DEG  C. under a pressure of 10-50 atmospheres and with agitation in the presence of a cobalt-containing catalyst for the reaction, the olefine, cyclo-olefine, acid or ester having a saturation vapour pressure of not more than one atmosphere at the temperature of the reaction and having at least one hydrogen atom attached to each carbon atom of the olefinic linkage.  The catalyst is preferably partly reduced cobalt oxide, activated with ferric oxide, and may be supported on an inert material, e.g. clay, kieselguhr, or bentonite.  The aldehydoacids obtained, or their esters, may be reduced or oxidized, using the same catalyst and hydrogen or air to the corresponding hydroxy-acids or dicarboxylic acids and esters or half-esters, and these esters may be saponified.  In examples, hydrogen and carbon monoxide are reacted with the following in presence of a cobalt-iron catalyst as above: (1) 1-octadecene; (2) pinene or dihydronaphthalene; (3) methyl oleate; (4) olive oil; (5) grapestone oil.  The product of (3) is oxidized to give methyl half-esters of diacids, and the products of (4) and (5) are reduced to glycerides of hydroxy acids.

Title: Improvements in and relating to automatic reclosing electric circuit breaker systems
IPC: H02H3/06
Filed: 1944-11-24
Abstract: 621,197. Protective cut-out systems. BRITISH THOMSON - HOUSTON CO., Ltd. Nov. 24, 1944, No. 23438. Convention date, Nov. 24, 1943. [Class 38(v)] Each circuit-breaker at the section-ends of a sectionalized A.C. circuit is provided with automatic reclosing means operable when the circuit-breaker is opened by means responsive to a fault on the section, and means for preventing the reclosing of the circuit-breaker when the latter is opened by means responsive to an out-ofstep condition (other than power swings) on the section. The circuit of the trip coil 15 is completed through contacts 16, 17 of devices 10, 11, responsive to the phasedisplacement of the system generating sources, and contacts 18, 19 of the directional starting and ohm units 12, 13 respectively of a distance relay 14. The occurrence of a fault on the section causes contacts-19 to close, thereby tripping circuitbreaker A1 and closing auxiliary contacts 20 which close the starting circuit of an automatic reclosing device 21, the contacts 22 of which energize the circuitbreaker reclosing coil 23. In order to render the device 21 inoperative on the occurrence of an out-of-step condition, the circuit of coil 23 is provided with contacts 25 of a relay 26, the operating winding of which is connected in series with contacts 27 of an ohm relay 28 and in parallel with contacts 30, 31 closed by the closing members of contacts 16, 17 of relays 10, 11. Relay 26 has a short delayed closing time and a long delayed opening time, and the reach of relay 28 is considerably longer than that of relay 14, so that for an out-of-step condition, contacts 27 close first, thereby opening contacts 25 before the circuitbreaker is tripped by the closing of contacts 16-19. In the case of a fault, relay 26 is not energized long enough to open contacts 25 before it is short-circuited by contacts 30, 31. If circuit-breaker A1 fails to remain closed for a predetermined time after any reclosure, reclosing device 21 and the drop-out time of relay 26 may be adjusted so that the return of relay 26 to its normal position after energization in response to an out-of-step condition, does not effect the reclosure of the circuitbreaker. Specification 441,606 is referred to.

Patent GB-642328-A (GB)
Title: Improvements in or relating to a character spacing mechanism for typewriting machines
IPC: H04L13/06
Filed: 1947-08-28
Abstract: 642,328. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 28, 1947, No. 23844. Convention date, Oct. 16, 1946. [Class 100 (iv)] In a typewriter with a power-operated typing mechanism, a mechanism for feeding a tape at letter space intervals is provided comprising a pair of feed rollers 32, 33 with means connected -to the power mechanism which constantly tends to rotate the rollers to feed the tape, a ratchet connection 50, 51 on one of the rollers, and a single feedcontrolling dog normally engaging the ratchet to prevent rotation of the feed rollers until released momentarily each time the typing mechanism is operated. The tape T, Fig. 1, coiled on a roll 25, is guided past a short platen 30 and drawn off by the roller 32 against which the tape is pressed by the spring-loaded roller 33. The roller 32 is mounted on a shaft 41 which as well as carrying the ratchet-wheel 50 has a pulley-wheel 42 constantly urged in a tape feeding direction by a coiled spring driving belt 43 driven from a continuously rotating power-driven pulley 44. The pulleys 42, 44 are constructed so that when the ratchet arm 51, Fig. 3, is in engagement with the ratchetwheel 50 the belt 43 slips on the pulleys. Upon the operation of a character key &c. a link 55 moves an arm 54 anticlockwise and a lug 54a thereon engages the end of the ratchet arm 51 releasing the wheel 50 which is then driven by the belt. The machine is fast in operation since the machine uses only one escapement ratchet arm which is withdrawn and released before the feeding ratchet-wheel 50 rotates more than one tooth space. As the pulley 42 is rotated the platen 30 is rotated and moved axially, to equalize wear, by interconnecting gearing 46, 47, a helical pinion 48, Fig. 1, and a gear-wheel 37 upon which is a raised bevelled cam disc 36 driving a bevelled portion 30a on the platen 30. The keys are either operated automatically by apparatus reading codes in a recording tape or manually by an operator receiving the code. The Specification as open to inspection under Sect. 91 comprises also a wholly manual machine in which a separate motor for actuating the tape feeding mechanism is provided. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,186,414. Computer input-output. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23865/67. Heading G4A. In a computer system, a notification signal from a data processor specifying only that a data transfer with a particular data handling means is required is supplied to priority logic in an input/output controller, the priority logic obtaining a control item relating to the data handling means to be involved in a data transfer from a control item store holding a plurality of such items relating to respective data handling means and storing it in the input/output controller, the control item controlling data transfer between the data handling means and a memory and being modified and restored in the control item store. Processors communicate via respective main memories with peripheral sub-systems (each comprising one or more input/output or bulk memory devices) via a common input/output controller and priorityordered peripheral channels (one per peripheral sub-system). The input/output controller is under overall control of control words (" control items ") from one (only) of the main memories, the relevant memory being selected by a control panel. The controller has its own microprogramme store, and buffer store for data transfers. The control word specifies the operation required, the address of the peripheral subsystem, the address of the particular device within the latter (if there are more than one), and in the case of data transfer, the first address in main memory to supply or receive data and the amount of data to be transferred. The control word is read from its main memory, used, the main memory address field in it incremented, and then stored back in main memory. Data, command and status parallel characters (with parity bit) can be transferred to and from the peripheral sub-systems, preceded by read or write clock signals in both directions. Further status and other signal lines are provided. A data transfer operation may be terminated by the peripheral sub-system or the input/output controller, when the required number of characters has been transferred, or on detection of an error by the peripheral subsystem.
