Title: Improvements in or relating to electrically-controlled cloth guiders
IPC: D06C3/00
Filed: 1923-08-17
Abstract: 224,943. Wood, A., and Wood, G. Aug. 17, 1923. Switches without quick action; contacts.-In apparatus for transversely guiding a travelling web of cloth, in which guide rollers engaging the selvedges of the, web are controlled by electromagnets the circuits of which are controlled by feeler levels engaging the selvedges, the magnet switches comprise a, stationary contact block and a bodily movable coacting block, which, in breaking the circuit; first slides on the stationary block and then moves rapidly out of contact with it, and, in closing the circuit, moves quickly into contact with, and then slides upon the stationary block. The flow and return leads of the magnet are connected to the terminals c<4>, c<3>, Fig. 12. The positive main is connected to a terminal c<2>, which by a lead d<4>, is connected to a metal plate d<2> which carries the movable contact block b and is fixed to a lever d of insulating material. This lever is pivoted freely at d<1> to the feeler lever e so that the block b rests upon the contact block a which is mounted on a metal plate a<2> carrying the, contact c<4> and is formed with a spur a<3>. When the web moves to one side of its correct path, it engages a pin e<1> on the lever e and moves this lever towards the position shown in dotted lines. The block b slides on the block a until the lever d, by engagement with the spur a<3>, is lifted thereby separating the blocks and breaking the circuit of the magnet. As the web returns to its correct position, the block b falls into contact with the block a and then slides back to normal position. In a modification, Fig. 14, in which the upper end of the feeler lever is acted upon by the web, the tilting of the lever d to separate the contact blocks is effected by that lever coming into engagement with a fixed pin a<4>. The contact blocks are preferably of highly refractory carbon and are shaped as shown to permit of ready adjustment or reversal when worn. They are preferably detachably held on their pins a<1>, b<1> by forked spring members, and the block b is provided with small holes, one of which engages a pin on the lever d to prevent accidental displacement of the block.

Title: Improvements in electrically-driven tools with electronic means for regulating the speeds of rotation
IPC: B23B45/02
Filed: 1969-04-28
Abstract: 1,220,015. Resistance motor controllers. METABOWERKE K.G. CLOSS, RAUCH & SCHNIZLER. 28 April, 1969 [31 May, 1968], No. 21508/69. Heading H1S. In an electrically driven tool whose air-cooled motor 3 is controlled by an electronic unit 7 regulated by a variable resistor 5 which is manually adjusted by a rotatable disc 9, overheating at low speeds is avoided by the provision of a spring 16 coiled round the axis 8 of the disc 9 which acts against the adjuster 9 (via a pin 22) when it is in the range of positions between a certain position at which the speed of the motor produces adequate cooling and the zero speed position. When the adjuster 9 is released, the spring 16 returns it to the said certain position. A stop 19 on the chassis 12 limits the spring 16 so that the adjuster 9 can remain in any position between the said certain position and the maximum speed position. Depression of the control disc 9 causes the electronic unit 7 to be by-passed, so that the tool may be driven at full-wave operation at full-voltage under control of the switch 10.
Patent GB-994027-A (GB)
Title: Improvements in or relating to werner complexes and methods of clathration therewith
IPC: B01J31/18
Filed: 1962-06-04
Abstract: The invention comprises a Werner complex of general formula Ni(SCN)2Xn which is insoluble, or sparingly soluble, in water at room temperature, wherein X is an alpha-arylalkylamine of the formula <FORM:0994027/C2/1> in which R1 is either hydrogen or a primary alkyl group and R2 is a phenyl group carrying two further halogen substituents on the 3- and 4-positions, and n is either 2 or 4. R1 preferably contains 1 to 10, more particularly 1 to 6, carbon atoms. The halogen substituents are conveniently identical and may be chlorine or bromine.  The complexes are made, according to an example, by adding a solution of the arylalkylamine in heptane, or heptane-chloroform mixture, at room temperature to an aqueous solution obtained by dissolving NiCl2.6H2O and KSCN in water, and separating the resulting precipitate by filtration.  Specific examples of amines are a (3,4-dichlorophenyl) ethylamine, a (3,4 - dichlorophenyl) butylamine, a (3,4 - dichlorophenyl) heptylamine, a (3,4 - dibromophenyl) ethylamine.  They may be prepared by reductive amination of the corresponding ketones, for instance by heating with ammonium formate.  Specifications 931,775, 935,099, 937,791 and 945,012 are referred to.ALSO:Clathrates of aromatic hydrocarbons are made using a Werner complex of the general formula Ni(SCN)2Xn, wherein X is an alpha-arylalkylamine of the formula <FORM:0994027/C4-C5/1> in which R1 is either hydrogen or a primary alkyl group and R2 is a phenyl group carrying two halogen substituents on the 3- and 4-positions, and n is 2 or 4.  The clathrates may be made heating a complex Ni(SCN)2X4 with one or more clathratable aromatic hydrocarbons to a temperature at which all the complex is dissociated into Ni(SCN)2X2 and 2X, and then cooling to effect recombination of the components to form the clathrate. Alternatively a complex Ni(SCN)2X2, at least two motor equivalents of amine X and at least one clathratable aromatic hydrocarbon are mixed together to form a clathrate in which the complex is Ni(SCN)2X4.  A mixture of aromatic hydrocarbons containing at least one such clathratable compound can be resolved by forming a clathrate with a complex of the type Ni(SCN)2X4 and the clathratable compound or compounds in the mixture, separating the clathrate from the mixture and dissociating the clathrate, e.g. by heating, treatment with an acid which does not react with the clathrated compounds, steam stripping or elution with an inert solvent.  In examples, isomers of di-isopropylbenzenes, cymenes, ethylisopropylbenzenes, cyclohexyltoluenes, and methylnaphthalenes are separated. Specifications 931,775, 935,099, 937,791 and 945,012 are referred to.
