Title: Production of polyners having chemically combined metal atoms
IPC: C08F4/06
Filed: 1967-08-18
Abstract: 1,188,556. Polymerization with pi-complex catalysts. BADISCHE ANILIN- & SODAFABRIK A.G. 18 Aug., 1967 [19 Aug., 1966], No. 38054/67. Heading C3P. Polymers of one or more olefinically unsaturated anionically polymerizable monomers are made by effecting the polymerization in the presence of an initiator consisting of a metal-picomplex which has a zerovalent central atom, the ligand component of the complex being twice metallized with an alkali metal and bearing no other substituents which interfere with the polymerization reaction. By "twice metallized" is meant that the ligand component contains two alkali metal atoms attached to different carbon atoms replacing two hydrogen atoms. Suitable complexes with a zero central atom are cyclopentadienyl iron, cobalt, and nickel, di-indenyl nickel, di-indenyl iron, and bis-(3,4-dihydronaphthalene). If desired the complexes may contain other aromatic radicals or hydrogen in addition to the cyclopentadienyl radicals, for example di-cyclopentadienylphenyl vanadium, dicyclopentadienyl tungsten hydride, or cyclopentadienyl cobalt toluyl. Further the complexes of cyclopentadiene or of benzene which also contain carbonyl, trialkylphosphine, or triarylphosphine are suitable as ligands. The metallizing reaction is known. It is usually effected in an inert organic solvent using propyl, butyl, or n-amyl sodium. The homo-, co-, and block polymers are generally formed by solution polymerization, for example in solvents selected from linear and cyclic ethers, hydrocarbons, hexamethylphosphoric acid triamide, tetramethyl urea, dimethyl sulphoxide, dimethyl formamide, or methylpyrrolidone. Suitable monomers are butadiene, isoprene, 1,1-dimethylbutadiene, 2,3-dimethylbutadiene, 1,1- diphenylbutadiene, styrene, alpha-methylstyrene, methacrylic acid esters, methacrylonitrile, and acrylonitrile. Exemplified polymers are oily polybutadiene, a block copolymer of styrene and butadiene, a block copolymer of styrene and isoprene, a block copolymer of 1,1- dimethylbutadiene and styrene, and a copolymer of acrylonitrile and methyl methacrylate. The polymers contain in chemical combination, small amounts of the metal of the catalyst.

Title: Switching arrangement for echo sounders
IPC: G01S15/96
Filed: 1968-08-09
Abstract: 1,212,108. Echo sounding. FRIED KRUPP G.m.b.H. 9 Aug., 1968 [12 Aug., 1967], No. 38103/68. Heading H4D. In an echo-sounder an echo recorder or indicator responds when the echo amplitude exceeds a threshold value, which is made dependent on the mean of the peak values of the echo amplitudes over several sounding periods. In the Fig. 2 embodiment, monostable circuit 9 blocks gate 8 for the duration of the transmitted acoustic pulse and then opens the gate to pass echo signals (which have been subjected to swept gain amplification to compensate for increased attenuation with range) to a long time-constant peak rectifier/integrator stage 10. A selected fraction of stage 10 output is applied to comparator 13 (a differential amplifier or polarized relay) and provides the threshold value with which the prevailing echo amplitude (i.e. the output of short time-constant rectifier stage 11) is compared. If the threshold is exceeded, comparator 13 triggers switching stage 14 (a monostable or bi-stable) whose output is used (a) to change the gain of an echo recorder amplifier so that e.g. sea-bed echoes are recorded grey, whereas fish echoes are recorded black, or vice versa; (b) as a bright-up signal for the rotating lamp display of a depth sounder; or (c) as a stop signal for a timercounter which gives a digital indication of sea depth and which is started when the acoustic pulse is transmitted.

Title: Method and apparatus for radiographic inspection
IPC: G01N23/04
Filed: 1958-12-02
Abstract: 915,391. Radiographic apparatus. ARVANETAKIS, K., and DONZIS, B. A. Dec. 2, 1958 [June 23, 1958; Sept. 15, 1958], No. 38778/58. Class 98 (1). [Also in Group XXIV] A method of making a radiographic film record comprises the steps of moving the ray source relatively to a body which is subjected to a parallel-sided beam of rays from the source, and locating a film at the side of the body remote from the source, the beam passing through the body to the film in a fixed direction during said relative movement. In the form shown, the ray source is an X-ray tube B supported in a travelling carriage A constructed as a framework. Cylindrical lead shields 86, 87 surround the tube to confine the X-rays to a narrow beam. A further removable shield 89 cuts off the lower half of this beam if required. The carriage A has four support arms 37 terminating in wheels 40 which run along the inner surface of pipe P and so support one end of the carriage in position inside the pipe. The other end of the carriage is supported by two arms 23 terminating in wheels 25 mounted in a skewed position with regard to the axis of the pipe. The framework supporting the wheels 25 is rotated by a motor 15, and owing to the skewed position of the wheels a longitudinal force is exerted on the framework, so that the whole carriage assembly is thus moved along the pipe. The photographic film is contained in a holder C (described in more detail in Specification 915,392), mounted on four wheels 72, and running along the outside of the pipe. A selsyn motor 43, mounted on the carriage A and belt-driven from one of the wheels 40, is connected to another selsyn motor 48 mounted on the film holder C where it is connected to a wheel 72. Thus the movement of the filmholder along the outside of the pipe can be synchronized to correspond with the movement of carriage A and X-ray tube B within the pipe. Consequently, a continuous film record of a longitudinal pipe weld may be obtained. In an alternative method for moving the carriage A through the pipe (Fig. 4, not shown), it is mounted on rails, and secured to an endless chain passing over sprockets at each end. In this modification, a variable pulley drive is provided by means of which the speed of movement of the carriage along the pipe can be varied. Also in this modification, the carriage can be moved transversely of the pipe, to bring it closer to one side. Instead of the movable film holder C, a number of stationary cassettes may be distributed along the top of the pipe.

Abstract: 1431457 Forming expanded mesh COMALCO (J & S) FTY Ltd 21 Aug 1973 [23 Aug 1972] 39672/73 Heading B5A [Also in Divisions B3 and E1] A method of forming expanded mesh comprises extruding extrusile material to form an extrusion of constant cross-sectional shape including ribs 21 and webs 22, forming a row of slots 24 in each web which are staggered with respect to the slots in an adjacent row, increasing the width of each slot in the two outermost rows of slots by bending at least one of the ribs flanking the respective slot, engaging hooks of two rows of hooks of an expanding machine in respective widened slots of the outermost rows of slots, separating the rows of hooks from one another so as to bend the ribs and expand the slotted extrusion and simultaneously moving the hooks in each row towards one another, and removing the expanded mesh from the hooks. Slotting of the extrusion 20 is performed by slotting rollers 29 keyed to a roller shaft 36. A spreader head 40 carries a pair of adjustable bearings which journal a spreader finger shaft 42. The relative heights of the shafts 36, 42 can therefore be adjusted to account for varying height of ribs 21 in different extrusions. A driving chain 46 extends between the shafts to drive the latter at identical speeds. The number of spreader fingers 47 is identical with the number of radially outstanding projections 31 when the shafts are driven at the same speed. After the extrusion has been slotted and the outermost rows of slots widened, the extrusion is driven by dogs 28 of a chain 27 to a discharge support 56. The expanding machine is provided with side rails 60 carrying a track 61 engaged by rollers 62 on carriage blocks 63. A workpiece engaging hook 65 is secured to each block 63 and the blocks are interconnected by a flexible line 66. A swinging gauge member 67 has hookengaging cut-outs 68 for accurately locating the hooks 65 when the member is swung downwardly. In the expansion of the workpiece the carriage blocks move towards each other until they abut one another. A slight degree of stretching can then be performed to remove any irregularities in the workpiece.
