Title: Novel benzofuran derivatives and a process for the manufacture thereof
Inventor: OSBOND JOHN MERVYN
IPC: C07D307/81
Filed: 1965-12-15
Abstract: The invention comprises compounds of the formula <FORM:1106059/C2/1> wherein R represents a C1- 4 alkyl group, S1 represents 5- or 7-(chloro or bromo) or 5,7-di-(chloro or bromo) substitution and S2 represents mono, di or tri (C1- 4 alkyl) according to the availability of position or positions, and acid addition salts thereof.  The compounds may be made by reducing a halo-ketone of the formula <FORM:1106059/C2/2> with an alkali-metal borohydride or with aluminium isopropoxide in isopropanol and reacting the resulting halohydrin with an amine of the formula RNH2 in the presence of an acid-binding agent and, if desired, converting the product into an acid addition salt.  As a variation, the halohydrin may be dehydrohalogenated to the corresponding epoxide prior to the reaction with the amine.  Halo-ketones of Formula II may be made by chlorinating or brominating the appropriate C1- 4 alkyl phenol, converting the product to the corresponding halo-alkyl-salicylaldehyde, e.g. using dichloromethyl methyl ether and titanium tetrachloride or using hexamethylene tetramine and paraformaldehyde, converting this to an alkali-metal salt, condensing this salt with chloro-acetone to form a halo-alkyl-2-acetyl-benzofuran and chlorinating or brominating the latter.  Pharmaceutical compositions, for use as adrenergic blocking agents, comprise compounds of the above Formula I in admixture with compatible pharmaceutical carriers.  The compositions may be administered orally or parenterally and may be in the form of tablets, pills, powders, capsules or granulates, or emulsions, solutions or suspensions.

Abstract: 1465998 Wound closing appliances C E KAWCHITCH 10 Dec 1974 [10 Dec 1973] 53412/74 Heading A5R A surgical appliance to close surgical incisions comprises an elongate, flexible tape 11, Fig. 1, and an elongate spring 12, Fig. 2, the tape comprising a flat strip 13 with parallel projecting ribs 14 providing a V-shaped channel which defines a course for an incision, the spring 12 comprising a single length of resilient wire bent to provide two sets of longitudinally aligned straight side portions 26 interconnected by connecting portions 27 of generally channel shape the spring being of an open ended channel shape, the straight side portions of one set being staggered relative to those of the other set, and the connecting portions 27 being successively oppositely inclined to the longitudinal direction of the spring gaps 28 being provided between portions 26, the spring being applicable to tape 11 by applicator (33), Fig. 3 (not shown) to enable ribs 14 to project into the spring and be clasped between the two sets of straight side portions 26 which engage laterally outwardly facing channels 19. Connecting portions 27 of spring 12 include V-shaped tongues 32 engaging within channel 18 in tape 11 when the' two members close an incision. Since in the relaxed condition the channel mouth between portions 26 is narrower than the distance between the sides 21 of channels 19, the spring will hold the ribs together when applicator (33) is removed. To provide a firm closure a thread 31 is tied between eyes 29 terminating the two spring ends and tightened to apply longitudinal compression. The strip underface is coated with a film 24 of biocompatible adhesive protected by a tear-off cover 25. The tape, of e.g. silicon rubber, tapers in thickness towards the side edges 20 and is perforated at 22 and additionally at 22A to provide weakness lines to facilitate separation of sections. In an alternative embodiment, Fig. 7, a flap 41 formed integrally with the wider of two ribs 14A is swung onto flat rims 42 of the ribs, its outer edge flange 49 engaging one rim 42 while its solid central tongue 51 enters a channel 43 between the ribs which contains a V-shaped groove 47 defining a course for the incision. After closing flap 41 a spring 12 is applied as before. In a further embodiment, Fig. 9 (not shown) ribs (14B) of equal width both have flaps (50) with tongues (52) fitting together in the channel between the ribs. A V-shaped tongue (53) on one flap fits into a similar groove (54) in the other to lock the flaps together.

Moreover, the turbocharger is equipped with an electric motorgenerator unit 18. Before the engine 1 is started, the turbocharger is rotated by the motorgenerator unit 18 so that air delivered from the blower 5 can be used for supporting combustion in the chamber 13 to produce driving gas for the turbine 6. A unit 11 controls ignition means 17, controls fuel valve 16 e.g. in accordance with a speed signal from the turbocharger, and preferably controls fuel flow rate to limit turbine speed and combustion-gas temperature to acceptable maximum values. The duct 12 includes a valve 19 which can be opened manually, or automatically when fuel is allowed to flow to the nozzle 14. As soon as the turbocharger is suitably driven by the gases from chamber 13, the starting circuit is switched off and electrical energy is supplied by the turbocharger generator for charging a battery 10, for assisting the latter in energizing a starting motor or motor and generator unit 2 to start the engine 1. The turbocharger may supply air for auxiliary apparatus before and after starting of the engine. The gases exhausted from the turbine 6 may be used to heat the air leaving the blower 5, or to heat air supplied to an airconditioning system receiving air from a second blower driven by the turbine 6.

Title: A frequency translation system, method and apparatus for the remote telemetry of data
IPC: H04J3/12

Abstract: 1,203,059. Transmitting digital values. H. B. ENG. CORP. 27 Nov., 1967 [25 Nov., 1966], No. 53961/67. Heading G4H. Decimal values are read from a remote station and transmitted to a central station by signals originating at the central station in the formof four frequencies D, E, F, G, Fig. 1, which are filtered out by filters 11-14, Fig. 2, at the remote station and combined at 15 in different combinations on ten leads so that each of which represents a decimal digit. A meter at the remote station has four decades each controlling the wiper of a selector switch, the ten contacts of which are connected to the output of the encoder 15. The frequency combinations representing the four digits are applied to four mixers also receiving groups of interrogation frequencies transmitted over the channel 10 from the central station. The interrogation frequencies pass through the filters 11-14 without change. The purpose of the first group of interrogation frequencies is to read out any digit signal containing a D frequency and it consists of four frequencies having values (D + H), (D + J), (D + K) and (D + M). Wiper 17 in the digit "5" position carries frequencies D and F. Similarly wiper 18 at digit "7" carries D, E and F. The D frequency is subtracted from the interrogation group of frequencies in mixers 22 and 23 giving frequencies which include frequencies J and K. The second decade is identified by filter 26 passing frequency J. The third decade is identified by frequency K. These two frequencies are combined, transmitted back to the central station and separated again by selector filters 31, 32. Each of the filters has a detector giving an output if the corresponding frequency is present. The D frequency represents the "1" bit in a four-bit binary sequence giving the decimal digit. This bit is stored in an appropriate position in four groups of four bit stores by a selector switch ganged to the selector switch which controls the interrogation signal. When this switch moves to the next position, to read out the "2" bits the group of frequencies sent is (E + H), (E + J), (E + K) and (E + M), and the return signals are stored in the second storage positions. When all four binary bits have been read out and stored the binary numbers are converted to decimal form and displayed on lamp units.
