Title: Triazolo benzo-diazepines
IPC: C07D403/06
Filed: 1975-12-19
Abstract: There are prepared 1-(2-phthalimidoalkyl)-6-phenyl-4H-s-triazolo- [4,3-a][1,4]benzodiazepine of the formula <IMAGE> in which R denotes hydrogen or an alkyl radical having 1 to 2 carbon atoms, the ring A is unsubstituted or substituted by a fluorine, chlorine or bromine atom or a nitro or trifluoromethyl group and the ring B is unsubstituted or substituted by 1 chlorine atom or 1 or 2 fluorine atoms. These compounds are obtained by hydroxymethylating a corresponding 2(4H-1,2,4-triazol-4-yl)benzophenone with formaldehyde. The hydroxymethyl compound is then reacted with a halogenating agent to give the halomethyl compound and this is finally cyclised by treatment with ammonia or hexamethylenetetramine in an inert organic solvent. The resulting compounds can be used as starting substances for the preparation of tranquillisers.

Abstract: 1,246,505. Weighing apparatus. H. CLESS. Nov. 14, 1968 [Nov. 24, 1967], No. 54102/68. Heading G1W. A weighing device comprising a pan 1 mounted at one end of a beam 3 on a carrier 2 which together with a link 4 forms a parallelogram linkage is provided with a spring 15 which is connected to the linkage in such a way that it may exert a torque on the carrier 2 only when a load is supported on the pan 1, the spring 15 being adjustably mounted so that its direction of action may be adjusted. To measure the percentage water content of a sample, the sample is supported on the pan 1 and the spring 15 is adjusted in tension until 0% is projected on to a screen 14 from a scale 10 on the beam 3. The sample is then dried and re-loaded on to the pan and without effecting further adjustment of the spring 15, the percentage water content can be read directly from the screen 14. The spring 15 is connected at its end remote from the linkage to a carriage 17 which is adjustable along a rod 18 by an element 19 which can be wound manually on to or from a drum 20, the drum 20 being connected to a scale 25 and rotatably mounted on a pivoted support 21 to which the rod 18 is attached. The tilt of the support 21 can be adjusted so as to ensure the spring 15 acts parallel to the link 4 under no load conditions of the load pan.

Abstract: 1482100 Pipe bending mandrel ROBINTECH Inc 17 Dec 1974 [17 Dec 1973] 54451/74 Heading B5A [Also in Division B3] A mandrel for supporting the walls of a tube during bending comprises a central flexible core and an expandable zone surrounding the core and formed of a series of adjoining but axially spaced interconnected passages having elastomeric walls whereby the cross-section of the mandrel can be increased to apply pressure to the tube walls and can be reduced in crosssection by dissipation of pressure from within the passages. In Fig. 1, the mandrel core 14 is a helically wound interlocked seam flexible metal tube offering a helical outer groove in which a rubber or PVC tube 19 is seated. Plugs 15, 17 are attached to the tube 14 by screws 16. A pilot head 12 is attached to plug 15, and a handle 13 to plug 17. A rubber sleeve 21 overlies tube 19, being received within the skirt 23 of head 12. Pipe 19 passes through grommeted apertures 25 in tube 14 and is connected to fluid pressure supply connections 32, 33. Handle 13 has a heat insulating sponge rubber sleeve. In use, pipe to be bent is heated and is placed over a support spigot, which serves to expand the pipe end. The mandrel is then inserted with pipe 19 unpressurized and contracted by sleeve 21. The pipe 19 is then pressurized to expand the mandrel, either with static fluid, or with circulating fluid under pressure which serves to cool and set the pipe as bent. Cooling fluid may also circulate through the spigot. The pipe is bent by hand or mechanically over a former, and then the the mandrel is depressurized and withdrawn. That part of the pipe which receives the pilot 12 and lies between the part which is to be bent, and the part which is expanded in the spigot, may be cooler than the other parts.

[Also in Divisions F2 and G6]. An installation comprising a rotary elasticfluid or hydraulic machine such as a blower, fan, compressor, pump or turbine removably mounted in a housing and communicating with an enclosed fluid-containing space, has means for isolating the space from the ambient when the machine is withdrawn from the housing for sevice or repair. As shown in Fig. 1, an electric motor driven blower unit 15, 16 is removably mounted via radial lugs 35, 36 in a housing formed within a steel-lined penetration 11 in a concrete pressure vessel 10 of a gas-cooled nuclear reactor, to recirculate the gases exhausted from a boiler 14. The blower unit includes rotatable guide vanes 22 adjustable by a removable actuator 26 via a shaft 25, coupling 54, 55, Fig.3, and gear-box 23. The blower unit can be withdrawn downwardly from the housing after the unit has been rotated to bring the lugs 35 between the lugs 36. However, before the blower unit can be withdrawn, the space within the pressure vessel is isolated by lowering a valve unit 40, comprising a sleeve 41 and a ring 43 slidably mounted on axial rods 42, into a position in which the ring 43 is sandwiched between the bottom surface of sleeve 41 and an upwardly-facing surface 70 of the housing, Fig. 2 (not shown). The valve unit 40 is prepared for lowering, after removal of the actuator 26, by lifting the shaft 25 to disengage the coupling 54, 55, engage a coupling 57, 58 and, via a rotatable frusto-conical sleeve 59, disengage locking tabs 52 on resilient locking fingers 51 from grooves 53 in a threaded shaft 46 screwed into the sleeve 41 and rotatably supported at its upper end by bearing means 61, 62. Thereafter, the shaft 25 is rotated in the appropriate direction to cause the shaft 48 to screw through the sleeve and thereby lower the valve unit 40.

Title: Underwater searchlight

Abstract: 1,235,260. Electric battery lamps; underwater searchlights. ELEKTRON A.G. 18 Nov., 1968 [22 Nov., 1968], No. 56301/69. Heading F4R. [Also in Divisions H1 and H2] An underwater searchlight comprises a watertight housing 1 containing a lamp 17 and three reed contact units 15a-15c which are actuable by a magnet 12 movable on the outside of the housing to control both the supply of power to the lamp and the energization of a motor 23 which moves the lamp axially to focus the beam of light. The magnet, which slides in a bore 10 in the handle 9 of the searchlight and is controlled by a thumb-wheel 14b, rests normally at the extreme left of the bore and on being moved to the right causes the contact unit 15b to close first followed by the contact unit 15c. The closure of unit 15c energizes relay 25c which closes contacts 30, 31, thereby completing the circuit to the lamp 17 and energizing relay 25b which closes contact 27 and changes contact 29 controlling motor 23. Further movement of the magnet opens unit 15b so that the lamp remains alight but does not move. On moving the magnet to close unit 15a the relay 25a becomes energized thereby closing contact 26, to keep relay 25c energized, and moving contact 28 to start the motor 23. The motor is stopped automatically at the extreme positions of the lamp by limit switches 33, 34. Return movement of the magnet to the position in which only unit 15b is closed causes contact 29 to change over and the motor to run in the opposite direction, thereby returning the lamp to its initial position. When the magnet is moved once again to its rest position the relay 25b is de-energized and contact 27 opens, thereby de-energizing relay 25c and switching off the lamp. The searchlight is powered by accumulators 8 and may be provided with an additional lower-power bulb which is also mounted in the reflector 16 and can be switched on and off by an additional reed contact unit.
