Title: Crimping or clamping tool
IPC: H01R43/042
Filed: 1964-12-14
Abstract: 1,090,024. Crimping tool. BURNDY CORPORATION. Dec. 14, 1964 [Dec. 13, 1963; April 2, 1964; June 12, 1964; July 1, 1964], No. 50776/64. Heading B3Q. A tool for crimping cable connectors has an operating mechanism which includes an eccentric cam which is rotated by a lever by means of a ratchet wheel or gear-wheel. In a first embodiment (Figs. 2, 4) two crimping jaws 5, 6 having M-shaped jaws are slidable in grooves 3 in the side pieces and are retained in position by a press bolt 9. The lower jaw abuts a cross bar 18 which is carried by plates 20 which are moved to close the jaws by eccentrics 21. A ratchet wheel 27 is mounted on the shaft 24 carrying the eccentrics 21 and the ratchet wheel 27 is rotated by a pawl 48 which is eccentrically mounted on the movable lever 63. In operation the lever 63 is oscillated and a pawl 29 prevents movement of the ratchet during return movement of lever 63. The pawl 29 can be disengaged by hand to allow the jaws to be reset using a tommy-bar (not shown) on the shaft 24. In a second embodiment (Fig. 6, not shown) the retaining bolt 9'is replaced by a yoke which is pivoted to one of the side pieces and which is held in position by a locking arm. In a third embodiment (Fig. 15, not shown) the ratchet wheel and pawl are replaced by a pinion and rack respectively having teeth of such shape that they can be operated in the same manner as the pawl and ratchet. However the rack is carried by a piston-rod mounted in the lever so that the rack can be reciprocated by hydraulic pressure to rotate the pinion. The tool can be operated mechanically (as in the first embodiment) or hydraulically. In a fourth embodiment (Fig. 19, not shown) the eccentric is mounted on a shaft carrying a pinion which is rotated by a pinion of the operating lever, a pawl engaging with each pinion so that oscillation of the lever causes uni-directional rotation of the pinions. The press jaws may be square and have an M-shaped jaw formed on each side.

Filed: 1964-12-15
Abstract: 1,080,499. Tuning arrangements. RANK BUSH MURPHY Ltd. Dec. 15, 1965 [Dec. 15, 1964], No. 51004/64. Heading H3Q. [Also in Division H2] A combined preset adjustment and switching mechanism suitable for use in television receivers comprises a plurality of interlocking push-buttons each of which when depressed actuates two switches (common to all the buttons) to individually pre-selectable conditions (for example, for waveband and standard selection respectively) and also produces a predetermined state of adjustment of a mechanism such as a tuning element. A four-position switch (not described) is actuated by a centrally pivoted lever (59, Fig. 2C, not shown) having its ends coupled to reciprocable L-shaped bars 41 and 42 while a two-position switch is similarly actuatable by bars 51 and 52. The movement of bars 41 and 42, when the button assembly 1, 2, 3, is depressed, is predetermined by the angular position of annular member 2 having four projections of which 21 and 23 are shown positioned to act on bars 41 and 42, respectively, while the movement of bars 51, and 52 is determined by the end of member 3 and a shoulder 32 thereon, respectively, the member 3 being angularly adjustable through 180 degrees to produce reverse actuation of bars 51 and 52 and the associated switch. The projections on member 2 are normally engaged in a cruciform opening in a support plate (50, Fig. 2D, not shown) and adjustment is effected by first pulling member 1 outwards against an internal spring (34, Fig. 5A, not shown) until member 2 is free of the cruciform opening and then rotating it to the desired position of member 2. On release of member 1, member 2 is re-engaged in the support plate and further rotation of member 1 presets member 3 only, member 2 being axially secured and angularly located on member 3 by wire springs (14, 15, Figs. 5A and 5B, not shown) engaging flats in the base of a groove (31); member 3 is secured to member 1 by a U-shaped spring wire clip (11, Figs. 5A and 5C, not shown). Button assembly 1, 2, 3, is rotatably mounted on an axially slidable shaft 9, the member 3 being urged against a shoulder (10) thereon by the internal spring (34). By pulling out a cap 17 which terminates a sleeve (18, Fig. 5A, not shown) axially slidable in member 1 against a light spring (19) an internally constricted portion (22) engages transverse projections (16) on the end of shaft 9 so that turning cap 17 rotates the shaft 9 to position a nut (81) threaded thereon but restrained from rotation (Figs. 2A and 2B, not shown). When the button assembly is depressed shaft 9 is moved longitudinally and the length projecting beyond nut (81) determines the adjustment thereby of a fine tuning device, for example, and hence cap 17 serves to preset this adjustment. The nut (81) co-operates with a known interlock mechanism (not described) to lock shaft 9 until another button assembly is depressed.

Abstract: 1429471 Iso- and terephthalic acids ATLANTIC RICHFIELD CO 5 Nov 1971 [29 Dec 1970] 51499/71 Heading C2C In a two-stage process for producing high purity terephthalic acid or isophahalic acid by oxidation with an oxygen-containing gas from C 8  hydrocarbon feedstock containing from 5 to 30% by weight of the isomer of xylene corresponding to the desired acid, the reaction mixture also containing from 70 to 95% by weight of a C 2-6  alkanoic acid solvent, said solvent containing a soluble metal compound catalyst in amounts from 0À2 to 2À0% by weight based on the weight of the reactants and the solvent, any water in the solvent being less than 10% by weight, said C 8  hydrocarbon feedstock is first oxidized substantially completely to the corresponding toluic acid at an essentially constant temperature in the range 200‹ to 280‹ F. while maintaining the pressure at about the vapour pressure of the reaction mixture, thereby producing a solvent-containing first stage effluent, some of the heat removal being attributable to the passage of inert gas through such first stage oxidation, such inert gas being admixed with the oxygen reactant and said effluent is advanced from the first stage oxidation to a second stage oxidation without subjecting said first stage effluent to liquid-liquid heat exchange and in said second stage oxidation, the product from the first oxidation stage is oxidized substantially completely to the desired benzene dicarboxylic acid at a temperature of from 230‹ to 280‹ F. and a pressure of from 200 to 800 p.s.i.g. A promoter may be employed in the process, e.g. an aldehyde, ketone, ozone or bromine. In the example isophthalic acid is obtained by oxidizing meta-xylene with air using acetic acid as solvent, cobalt acetate as catalyst and acetaldehyde as promoter.

Abstract: 1,120,629. Printing. LITTON INDUSTRIES Inc. 7 Dec., 1965 [16 Feb., 1965], No. 51867/65. Heading B6C. A permanent pattern is produced on the surface of a material having comparatively low absorption characteristics for a frequency range of radiated electromagnetic energy by applying to the surface in the desired pattern, e.g. by printing, a substance including finely divided material having comparatively high absorption characteristics for said frequency range, the substance having a component which is heat bondable to the material of the surface, and exposing the applied substance to radiated electromagnetic energy including substantially said frequency range, to raise the temperature of the applied substance to a level at which bonding occurs. The substance may be an ink including a pigment powder forming the finely divided material e.g. carbon, (graphite) manganese dioxide, iron oxide or nickel oxide, and a base including at least one component capable of being heat-bonded to the material of the surface. The base may be a suspension of the component in a volatile liquid carrier and the component may be of the same material as the surface e.g. a synthetic plastics material such as polypropylene, polyvinyl, stryene and cellulose acetates and nitrates. The radiant energy source may vary from infra-red to ultra-voilet depending upon the absorption characteristics of the finely divided material used and may be an infra-red bulb. The energy may be radiated in pulses e.g. 0À01-0À1 seconds. The ink may be applied by stencil, silk screen, press, brush or electrostatic methods. A typewriter ribbon may be impregnated with the ink and the ink deposited on the surface by typing.

Abstract: 1396147 Magneto-optic storage systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Nov 1972 [13 Nov 1971] 51939/72 Heading H3B In a magneto-optic storage system modulated radiation is scanned across a sheet of bubble domain material filled with cylindrical domains which are converted to strip domains by the rise of temperature caused by the radiation. The increase of size of the domains when they change to strips is detected by transmitting a low power polarized beam through, the sheet and an analyser to a photo-detector. Each information bit may comprise one domain, in which case the radiation beams for reading and writing are similar in size to the domain, or may comprise several domains in which case larger beams are used thus easing alignment. In Fig. 5, light from laser 13 passes via beam combiner 15, lens 14, modulator/deflector 16, polarizer 18 to magnetic sheet 9. The sheet is maintained at a suitable temperature by plate 10 and a magnetic bias is imposed by coil 12. During writing the laser light heats selected areas of the sheet to change the domain shape under control of input 17. For reading a low power light source 22 passes light to the sheet and to analyser 19 which is set to pass light from the domains and block light from the rest of the sheet. The light is detected at 21. To erase the sheet a separate coil (not shown), is activated to create a suitably directed strong field; several such coils may be used to erase only parts of the sheet. The hysteresis curve of the change from circular to strip domains is given, Fig. 1 (not shown). A suitable material is Gd 2 . 32 Tb 0 . 59 Eu 0 . 09 Fe 5 O 12  held at 25‹ C.

Abstract: 1,180,256. Protective arrangements. K. DIEHL. 16 Nov., 1967 [23 Nov., 1966], No. 52139/67. Heading H2K. [Also in Division G3] An overload disconnecting arrangement for an automatic voltage control circuit of the type having a series transistor 44 the base of which is connected through a resistor to the collector or a suitable auxiliary voltage, and the emitter being connected to a potential divider 46, 47 across which the stabilized output voltage is obtained, transistor 44 being controlled by a second transistor 15 the base of which is connected to a tapping on the potential divider and its emitter connected through a reference voltage source to the earthed terminal of the divider and its collector connected to the base of transistor 44, comprises a switching device which in the event of overloads is operated by a continuous signal generated in the circuit whereby the base of the transistor 44 is connected to a reference potential, and further means are provided which after the elimination of the overload and after transmission of an appropriate signal, by non automatic means, switch the device into an inoperative condition until such a time as the output voltage has been restored. The circuit may be adapted for disconnecting all of a plurality of related outputs of differing polarity U1, U2 wherein the bases of the transistors, e.g. 44, 54 are connected to a common reference potential, and all the outputs are disconnected substantially simultaneously. If the output U2 is overloaded a resistor 70 is shunted hence the base potential of a transistor 60 rises rendering this transistor conductive thus blocking transistor 44 and subsequently transistor 54. When the fault is eliminated a switch 67 is reversed hence charging a capacitor 66 rendering a transistor 61 conductive thus blocking transistor 60 and rendering transistors 44, 54 conductive. When capacitor 66 is fully charged transistor 61 is again blocked. If output U1 is overloaded the transistor 54 is immediately blocked rendering transistor 60 conductive and hence again blocking transistor 44. The arrangement may disconnect further outputs, e.g. (U3), Fig. 4 (not shown), in a similar manner. In this arrangement the capacitor 66 is replaced by an inductor (116). A fuse (39), Fig. 2 (not shown), may be included in the circuit. Transistor 44 may be controlled by further transistors (not shown) connected in cascade.
