Title: Junction equipment for a system of electrical distribution bars
IPC: H02G5/08
Filed: 1960-07-08
Abstract: 909,117. Distribution systems; two-part couplings. TELEMECANIQUE ELECTRIQUE. July 8, 1960 [Sept. 11, 1959], No. 23982/60. Classes 36 and 38 (1). A junction element enabling a supply to be tapped from main conductor bars, carried in a conduit, consists of conductor bars held in insulators in a split conduit and having secured to their ends, spring-pressed projecting clamp connectors, which can be passed through an opening in the main conduit to grip the main conductor bars, the junction element being secured in place by a U-member encircling the main conduit. Fig. 1 shows the junction member having the upper half la of the conduit shorter than the lower half 1b, the conductor bars 3 being of intermediate length and an aperture 23 in the lower conduit part 1b being arranged opposite the ends of bars 3, being closed by a cover. The conductor bars 3 are supported by insulators 4 held in the two unequal halves of the conduit 1a, 1b, and are held in longitudinal position by several bars of non- conducting material 18 (Fig. 5) passing through the conduit and conductor bars. The junction element can be extended by extention lengths, consisting of two equal halves of conduit displaced longitudinally containing a set of conductor bars 31 (Fig. 8), equal in length to the conduit halves and placed in the conduit so as to abut (Fig. 10, not shown) with the ends of conductors 3, when the largest principal conductor bars are clamped onto. To keep the dimension D (Fig. 8) constant, with different sizes of main circuit conductor bars, the holes 30 in the longer half of conduit section 1b, allowing for connection to the extention length of conduit, are elongated and U-pieces 29 are welded on to the sections 1a, 1b, enabling the junction element to slide longitudinally with respect to the main circuit conductor bars. The conductor bars are terminated in clamps 11 (Fig. 5) projecting from the end of the conduit la, 1b and secured to the conductor bars by bolts 13 which also hold springs 12 against the split jaws (Fig. 6, not shown) of clamp 11, increasing their resilience. The clamps 11 are enclosed in insulating sleeves 14 of the same width as the distance between the conductor bars, and having openings 14a to allow access to the jaws of the clamp. The sleeves are held in place by the non-conducting rod 15 and by the end of the sleeves abutting with the first insulator 4 (Fig. 1). The bar 15 also passes through an earthing bar 7 running parallel with the conductors, and forced into contact with the corresponding strip in the principal circuit conduit by spring 16. Angle 20 (Fig. 4, not shown), is fixed to the longer conduit section 1b, and has threaded clamp 21 passed through the face 20a (Fig. 2) which lies flush with the end of conduit 1a, 1b. In use the junction may be required to couple on to the principal circuit conduit at some other angle than 90 degrees, for this connection face 20a and end of conduit sections 1a, 1b are inclined at the required angle to the conductor bar axis.

Class 40(1) [Also in Groups XXVI and XXIX] In a system for measuring the rate of flow of, for example, fuel in a pipe 10, a rotor 11 in the pipe is geared to an electric motor the speed of which is controlled so as to oppose increases in the pressure difference between the upstream and downstream sides of the rotor. The rate of flow is shown on a meter 18 connected to a tachometer generator driven by the motor. This arrangement' compensates for changes in viscosity. The differential pressure may be measured by a device in which a pair of diaphragms responsive to the respective pressures act on a lever operating on the armatures of a pair of E-type transformers connected in opposition, Figs. 2 and 3 (not shown). In a somewhat similar arrangement, Fig. 4, the lever carries unsymmetrical elements 35 completing the magnetic circuit of U-type transformers. In another arrangement, Fig. 5, a single diaphragm 40 controls a common armature 50 in relation to a pair of differentiallyconnected but unequal transformers. The output of the sensitive device acts on the motor via a magnetic amplifier 25.

Patent GB-246156-A (GB)
Abstract: 246,156. Soc. of Chemical Industry in Basle. Jan. 14, 1925, [Convention date]. Anthracene-2-thioglycollic acid is obtained either by condensing 2-mercaptoanthracene with a monohalogen acetic acid or by reducing anthraquinona-2-bhioglycollic acid. According to examples (1) 2-mercaptoanthracene is condensed with chloroacetic acid in alkaline solution; (2) anthraquinone-2-thioglycollic acid is reduced with zinc dust and aqueous ammonia. Anthracene-2 : 1-thioindoxyl is made by converting the above-described anthracene-2-thioglycollic acid into its acid chloride by means of an inorganic oxy-acid halide such as phosphorus pentachloride and then effecting ring closure with a.n acid condensing agent such as aluminium chloride. According to an example phosphorus pentachloride is used to effect the first step and alluminium chloride in chlorbenzene for the second. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of thionyl chloride for producing the anthracene-2-thioglycollie acid chloride and to the use of ferric and zinc chlorides for effecting the ring closure.

Abstract: 1394280 Electromagnetically controlled fuel injectors ROBERT BOSCH GmbH 26 May 1972 [28 May 1971] 24831/72 Heading F1B A fuel injection pump nozzle comprises a pump piston 15 Fig. 1 driven by a larger servopiston 14, the nozzle being connectible to a pressurized fuel source arranged to feed fuel to the pump piston, servopiston and to a valve spool 12 via an electromagnetically operable valve 18, Fig.2 operable in synchronism with an I.C. engine, the valve spool controlling the flow of fuel to and from the servopiston to control the pumping and return stokes of the pump piston 15 which has an oblique control edge 21 co-operating with a control bore 23 to control the termination of injection and injection quantity in dependence on the rotary position of the pump piston. The pump working chamber 24, Fig.3 is fed via line 26 through a throttling gap 'a' at the end of the return stroke (T.D.C.) and returns fuel to the reservoir through bore 23 entraining any bubbles present in working chamber 24. During the pumping stroke of piston 15 the fuel passes through valve 37 and lines 49, 51 to chamber 52 where fuel pressure acts on surface 53 to open the valve needle 44. Chambers 45, 55, 56 and groove 54 communicate with bore 57 to return leakage fuel. Operation: In the Fig. 3 position the servo pressure chamber 95 is connected to a pressure source 105, the pressure of which may be engine speed or load dependent, so that servopiston 14  moves pump piston 15 downwardly against spring 65. The gap "a" and then bore 23 is closed to commence injection. Injection is terminated when edge 21 opens bore 23, Fig. 4 to relieve chamber 24 to reservoir 111 via groove 32 and line 33. Valve 17 retains a predetermined pressure in lines 49 and 51. With the termination of injection the solenoid valve 18 is changed to its Fig.4 position by a signal from an electronic control device 115. The latter determines the switching times of the valve 18 in dependence on a speed signal from tachogenerator 116 a pump piston position signal from position sensor 117 and a desired value signal from a regulator 119. In a modification the connections to the solenoid valve 18 and valve spool 12 are arranged so that the electromagnet is energized during the pressure stroke. In another modification the solenoid valve return line 79, Fig. 2 is led back to chamber 96.
