Title: Improvements relating to electrically insulating components
IPC: H01F41/12
Filed: 1963-09-04
Abstract: 1,059,122. Insulation; transformers. LICENTIA - PATENT - VERWALTUNGS G.m.b.H. Sept. 4, 1963 [Sept. 5, 1962], No. 34994/63. Headings H1A and HIT. Resilient insulating components are made by winding paper or other tape around a former to a set thickness whilst partially cementing the layers together, then cutting through the resultant coating and removing portions thereof. Further shaping may be effected after removal. In a method for making rings of L-shaped crosssection for transformer insulation an annular former of rectangular cross-section 58, Fig. 5, is provided with an underlay consisting of pulp board cylinders 59 (inner), 61 (outer) and discs 60, 62 upon which overlapping paper tape is helically wound in layers, and possibly alternately in opposite directions and with pressboard inserts, to constitute coating 63. During the winding operation the applied wrapping is cemented at various places. By making cuts 64, 65 at the cylindrical surfaces and cuts 66, 67 at the end faces, four angle rings are obtained. In Fig. 4 an interposed staggered joint of uncemented material is provided by winding in strips 52, 56, 57 &c. A ring-shaped box-like former made of replaceable disc members and rings, one of which may have part conical surfaces, may be provided (Fig. 6, not shown). In another embodiment, Figs. 7 and 8, tape is wound on a thin cylindrical former 73 but only the inner layers 75 of the wrapping are cemented whilst the outer layers 74 are not cemented. Cuts are made inside and out along lines 76 when the uncemented tape ends may be fanned out radially, to form two components of L-shaped cross-sections, press-board discs 79, 80 and cementing clips 81 retaining the shapes. The cuts may be made at one end of the cylinder if one ring of twice the size is required. A similar method may be applied using a flat disc-shaped former. If an insulating former is used, part may be retained within the completed ring, to enhance its insulating properties. Other reinforcing pieces may be inserted and components made in this way may be further treated by heating and/or a pressing operation. Components of other than those having L-shaped cross-sections may be made, for example, of conical form.

Title: Process for manufacturing conjugated diolefin copolymers
IPC: C08F236/04
Filed: 1965-08-16
Abstract: Diolefin copolymers containing a butadiene unit having a high cis-1,4-structure are made by copolymerizng butadiene and a hydrocarbon-radical-substituted butadiene in which the substituents are selected from alkyl, aryl, or cycloalkyl radicals, in the presence of a diluent, at a temperature in the range of -30 DEG  C. to 150 DEG  C. and under a pressure sufficient to maintain the reaction system in the liquid phase, and a three-component catalyst. The catalyst consists of (A) a metal salt of an organic carboxylic acid of the formula <FORM:1047788/C3/1> where R is a hydrocarbon radical, M is a metal, and n the valency of the metal, or a hydroxyketone metal complex, or a hydroxy ester metal complex, or a hydroxyaldehyde metal complex, or a hydroxyacid metal complex, or a diketonedioximo metal complex, or an 8-hydroxyquinoline metal complex, or a cyclodiolefin metal complex, or a carbonyl metal complex, and in all cases the metal is nickel or cobalt, (B) boron trifluoride or its complexes with oxygen-containing organic compounds, and (C) an organometallic compound selected from alkyllithiums, dialkylzincs, trialkylaluminiums, and dialkylalkoxy-aluminium compounds.  The mole ratio of the (C) component to the (A) component is at least 0.5, and the mole ratio of the (C) component to the (B) component being within the range of 0.1 to 5.0.  All or two of the catalyst components are soluble in organic solvents.  The comonomer may be isoprene, 2,3-dimethylbutadiene, or 1,3-pentadiene.  The copolymers may be made by normal or block techniques.  Both of these types of copolymers are exemplified.  The copolymerization is preferably effected in a hydrocarbon solvent or diluent. Recovery of the copolymer is by conventional techniques. The Specification contains long lists of catalyst components. Exemplified catalysts are (1) nickel naphthenate, boron trifluoride etherate, and triethyl aluminium, (2) as (1) but nickel salt replaced by acetylacetone nickel, (3) as (1) but nickel salt, nickel 2-ethylhexoate, (4) as (1) but acetylacetone cobalt used instead of Ni salt, (5) as (1) but instead of Ni salt, the ethyl acetoacetonate salt of Ni or Co used, (6) tetracarbonyl Ni, (C2H5)3Al, and BF3 etherate, (7) as (6) but Ni compound replaced by salicylaldehyde Co or Ni, nickel benzoate, or nickel stearate, and (8) acetylacetone Ni, or Ni naphthenate, BF3 etherate, and butyl lithium or diethyl zinc, or diethylmonoethoxy aluminium.  The copolymers may be vulcanized.
Patent GB-474945-A (GB)
Title: Improvements in or relating to copying appliances for metal-cutting and like machine tools
IPC: B23Q35/42
Filed: 1936-12-24
Abstract: 474,945. Copying-mechanism. HASSE & WREDE GES., C., and STUDINGER, E. Dec. 24, 1936, No. 35380. [Class 83 (iii)] In a copying-machine wherein the tool &c. is guided by a roller following a cam or template and wherein a return cam is provided for retracting the tool out of contact with the work, the two cams are arranged in different planes with respect to the axis of the roller so that axial displacement of the roller will cause it to engage one cam or the other. As applied to an automatic lathe the tool-holder 1 carries a roller 3 freely rotatable on a pivot 2 and engaging a guide cam 4 secured to a stationary part of the machine. During the inoperative return traverse of the tool-slide, the roller 3 engages the return cam 5, the distance a between the cams 4, 5 being less than the diameter b of the roller so that the latter cannot move from one cam to the other during a traverse in either direction. At the end positions 3a, 3b, Fig. 4, where reversal of the traverse takes place, the distance between the cams is widened to a dimension c so that the roller may be moved axially from one cam to the other. This movement is caused by one of the two rollers 11<1>, 11<11>, Fig. 1, on a lever 9 connected to the roller 3 by a yoke 8, engaging the ramps 7<1>, 7<11> at the reversing positions of the holder. The lever 9 is held in its two extreme positions by means of a spring-pressed sleeve 13, Fig. 3 (not shown). The toolholder may be brought to rest, for changing of the work, when the roller 3 arrives at position 3b, or may commence another operative traverse in contact with cam 4 if the work is changed automatically. Aspring-pressed roller 15, Fig. 1, engages a cam surface 17 to maintain the roller 3 in contact with the cam 4, and the roller 3 may be stationary whilst the cams 4, 5 are traversed.

Abstract: 764,090. Springs &c. vehicle suspensions. METALASTIK, Ltd. Dec. 15, 1954 [Dec. 21, 1953], No. 35464/53. Classes 103(6) and 108(3). A resilient support comprises a metal plate 19 bonded to rubber blocks 12, 121, also bonded respectively to a supported part 11 and a supporting part 3, and a friction pad 24 between the plate 19 and the part 3, arranged so that the pressure between the plate 19 and the part 3 increases with load on the part 11, and so .that slip occurs upon a sufficient load whereby loading is imposed upon the block 12<SP>1</SP>. As shewn, applied to a bolster mounting for a railway vehicle similar to that described in Specification 648,516, the part 11 is also supported by a further pair of blocks 13, 13<SP>1</SP>, which are bonded to a respective plate 19. There are two friction pads 24 associated with upper and lower ends respectively of each plate 19. The pads 24 are carried by parts rigid with the part 3. The lower pad however may be carried by the plate 19. In an alternative arrangement, the two pads are mounted laterally, and both act on the lower end of the plate 19. In this latter arrangement, the proportion of transverse spacing at the friction pads, to their vertical distance from the centre of the spring, may be arranged so that the friction force in the horizontal direction may have the same ratio to that in the vertical direction as the respective stiffnesses. In operation, under a small load, the plate 19 is held by the friction of the blocks 24, and the blocks 12, 13, only, are in operation. On further loading, the friction force is overcome, and the blocks 121, 13<SP>1</SP>, are then brought into operation. The invention is also applicable to the independent front wheel suspension of road vehicles.

Abstract: 1358756 Photographic cameras AGFAGEVAERT AG 30 July 1971 [30 July 1970] 35983/71 Heading G2A A camera having a rotatable socket 21 for a percussive flash-cube contains an impact member 9 and a drive member 6, the latter being movable between two positions, a spring 7 urging the drive member 6 into a first position and a slider 2 bringing the drive member 6 into the second position (shown) where it is releasably held by a lug 2b of the slider 2. When a flashcube is attached, movement of the member 6 to the second position rotates the unit, and movement of the member 6 to the first position drives the impact member 9 to ignite a flash-bulb. As shown, no flash-cube is attached. When the slider 2 is released by depression of a shutter release member 5, the drive member 6 is retained in the position shown by a pin 10. The slider 2 moves to the right (as seen) under spring action, thereby operating a shutter blade 3. The slider 2, which also prevents double exposure, is retensioned by rotation of a cam wheel l connected to a film transport handle. Insertion of a flashcube depresses a spindle 12 which rotates an exposure time change-over lever 13 and also moves the pin 10 out of contact with the member 6. In this case, when the release member 5 is depressed, the member 6 follows the slider 2 and strikes the impact member 9 to initiate the flash. Retensioning of the slider 2 also retensions the member 6. A lug 6d of the member 6 simultaneously entrains an advancing lever 14 to rotate the socket 21. In another embodiment Figs. 2, 3 (not shown) a pawl lever (25) holds the impact member (9) to prevent accidental firing if a flash-cube is inserted when the slider (2) has run down.
