Title: Ketones and process for the manufacture thereof
IPC: C07D307/12
Filed: 1965-12-09
Abstract: The invention comprises tetrahydropyran derivatives of formula <FORM:1089739/C2/1> tetrahydrofuran derivatives of formula <FORM:1089739/C2/2> and hydroxy ketones of formula <FORM:1089739/C2/3> wherein R1 is a C1- 6 alkyl group which ma be substituted by a free, esterified or etherified hydroxy group; a C1- 6 alkenyl, aralkyl or aryl group, or together with R2 a C1- 6 alkylene group; R2 is a C1- 6 alkyl group; R3, R4 an R5 are the same or different and are hydrogen or a C1- 6 alkyl group; R6 is hydrogen or a C1- 6 alkyl or alkenyl group; R7 is hydrogen or a C1- 6 alkyl group which may be substituted by a free, esterified or etherified hydroxy group; and R8 is a lower alkyl group which may be substituted by a free, esterified, or etherified hydroxy group; a lower alkenyl or an aryl group.  The compounds of Formulae IV and V are prepared by reacting a g ,d -unsaturated aldehyde of the general formula R1R2C=CR3CH(R4)C(R5R6)CHO (I) with a ketone of formula R7CH2C(O)R8 (II) in the presence of an alkaline condensation agent, whereupon the resulting hydroxy-ketone of the general Formula III above is cyclized in the presence of an acid cyclization agent to give a mixture of the two heterocyclic ketones above.  Suitable alkaline condensing agents are alkali alcoholates and alkali or alkaline earth metal hydroxides. The acid cyclization agent is suitably a mineral, hydrohalic or a strong organic acid.  In those cases where R3 in the compounds of Formulae (I) and (III) represents hydrogen the end product is predominantly a tetrahydropyran, whereas when R3 is a lower alkyl group, tetrahydrofurans are predominantly formed.  The mixtures may be resolved by fractional distillation or chromatography.

Abstract: 1283445 Data transmission systems INTERNATIONAL BUSINESS MACHINES CORP 9 Nov 1970 [10 Nov 1969] 53154/70 Heading H4P In a data processing system a number of remote stations, each having one or more terminal units, such as input/output typewriters, are connected in a loop with a central station which gathers messages from the terminal units for transmission to a central computer or distributers messages from the central computer. Communication between the remote stations and the central station is by multi-bit words which circulate round the loop. Each station receives each word in turn, interogates it to see for example if the word is free or is addressed to that station, is able to modify it and pass it on to the next station. Each input/output terminal has an operators calling key which causes the associated remote station to seize the next multi-bit word marked free, and to insert a calling signal character and the address of the calling terminal. A mechanical key-loose lock prevents the keying-in of data until a proceed to send signal has been received from the central station in the same multi-bit word. Transmission of a message proceeds using the word and at the end the central station sends an end of message signal to free the remote station, reset the lock, and also frees the multi-bit word. The central station can only accommodate a limited number of transmitting terminals and after that a calling terminal is queued and a free multi-bit word allocated on a priority basis. In addition to the free/busy bit, the multi-bit words contain an acknowledge and sequence bit, a bit indicating whether message transmission is to or from the central station and a parity bit.
Patent GB-533822-A (GB)
Abstract: 533,822. Directive wireless systems. PHILIPS LAMPS, Ltd. Nov. 30, 1939, No. 31166. Convention date, Dec. 3, 1938. [Class 40 (v)] A course indicator for an overlapping-beam system is fed by two push-pull amplifiers, which are arranged so that the application of a signal to one amplifier automatically blocks the other for a period equal to the interval between two complementary signals. Since the rectified equivalent of one signal a, Fig. 2, is initiated by an impulse b of opposite polarity to that d of the complementary signal c, the deflection of the indicator needle is thus determined by the first half-wave of the signal received. As shown in Fig. 1, the rectified signals are fed at 2 to the grids of push-pull amplifiers 5, 6, which are biased near the cut-off point and feed an indicator 13 in shunt with a potentiometer 11. A signal fed say to the grid of valve 5 applies a blocking-bias to the grid of the valve 6 through an anode resistance 20, rectifier 28, and condenser 26. The charge on this condenser leaks away through a resistance 30 at the end of the first half-wave of each impulse. If the incoming impulse is of opposite polarity, it will affect the valve 6 but will block the valve 5. In either case the indicator needle is given a steady deflection.
