Title: Improvements in or relating to spring-driven impulse dials of the type used in telephone systems
IPC: H04M1/31
Filed: 1938-01-18
Abstract: 509,827. Impulse transmitters. STANDARD TELEPHONES & CABLES, Ltd., GRACE, B. B., and SPARKES, H. H. J. Jan. 18, 1938, No. 1672. [Class 40 (iv)] [Also in Group XXXIV] In a spring-driven impulse dial of the type used in telephone systems, the speed at which the spring drives the impulse wheel is controlled by magnetic forces. In Fig. 1, steel rollers or balls 7 are interposed in a circular track between a rotatable soft iron disc 6 and a stationary soft iron ring 1 secured to a permanent magnet 2 having the inner and outer peripheries of opposite polarity. The disc 6 is adapted to be coupled to the finger plate 8 by a coil spring clutch 10 so that when the plate is turned to the stop 11 to select the required digit the disc 6 remains at rest, but it is rotated with the plate when this is returned. The reluctance to rotation of the rollers and the eddy current and hysteresis effects produce a braking action dependent on the speed. The balls 7 may be nickel or chromium plated to increase the magnetic reluctance. In another construction, Fig. 2, an annular magnet 21 has a spirally formed face 22 engaged by a similar face 27 on a second magnet or a soft iron disc 26 coupled to the finger plate 29 by pins 30 slidable in holes in a flange 31 on the plate. The magnet or disc 26 thus moves towards the magnet 21 when the plate 29 is turned to select the digit, but is moved away from the magnet 21 when the plate is returned by the driving spring giving a braking action due to the magnetic attraction, eddy current and hysteresis effects and which varies with the driving force since the distance apart of the disc and magnet increases as the strength of the spring decreases. According to the Provisional Specification, the brake may comprise a soft iron stator and rotor, one or both energized by a permanent magnet so as to produce a magnetic drag and which may have a winding arranged to be short-circuited by a switch spring only when the mechanism is being driven by the spring.

Title: The production of tertiary phosphites including new cyclic phosphites
IPC: C07F9/6574
Filed: 1961-01-16
Abstract: A tertiary phosphite is obtained by transesterifying tris 2-chloropropyl phosphite with an alcohol having a higher boiling point than propylene chlorhydrin or by transesterifying tris 2-chlorobutyl phosphite with an alcohol having a higher boiling point than 2-chlorobutanol. The alcohol may be monohydric or polyhydric, e.g. an alkanol or cycloalkanol such as n-hexanol, n-heptanol, n-octanol, 2-ethylhexanol, isoctyl alcohol, octanol-2, 2-methyl-heptanol-2, n-decyl, isodecyl-, lauryl-, myristyl-, cetyl- or stearyl alcohol, cyclohexanol, or methyl cyclohexanol, or a glycol e.g. ethylene-, propylene-, trimethylene-, 1, 2-butylene-, 2, 3-butylene-, 1, 4-butylene-, 1, 3-butylene- or neopentyl-glycol, 1, 6-hexanediol, pinacol, 1, 2-pentanediol, 2-methyl-2, 4-pentanediol, 2-ethyl, 1, 3-hexanediol, 2, 4-pentanediol, 2, 4-heptanediol, 2, 2-diethyl-1, 3-propanediol and 2-ethyl-2-n-butyl 1, 3-propanediol. The transesterification of the tris-2-chloropropyl phosphite can be carried out at from room temperature to the boiling point of propylene chlorhydrin and at atmospheric or sub-atmospheric pressure, preferably the latter, e.g. a pressure of 50 mm or less. Mixed phosphites, e.g. diceryl (or distearyl) 2-chloropropyl phosphite, may be obtained by using less than 3 moles of the monohydric alcohol per mole of tris 2-chloropropyl phosphite. When using a , b  or a , g glycols in an amount of one equivalent (or more) of the polyhydric alcohol per equivalent of tris 2-chloropropyl phosphite, e.g. 3 moles of glycol with 2-moles of tris 2-chloropropyl phosphite cyclic phosphites of the general formula: <FORM:0944726/C2/1> are obtained wherein R1, R2, R3, R4, R5 and R6 are hydrogen or C1-C4 alkyl radicals and n is 0 or 1.  If less than one equivalent of the diol is used products are formed which still contain a 2-chloropropyl group, thus when reacting one mole of tris 2-chloropropyl phosphite with one mole (or less) of the above diols there are formed products of the general formula: <FORM:0944726/C2/2> wherein R1, R2, R3, R4, R5 and R6 are hydrogen or C1-C4 alkyl and n is 0 or 1.  The invention includes per se compounds of the first general formula given above and compounds of the second general formula given above in which n is 1.  The products are useful as insecticides and as stabilizers or plasticizers for plastics, e.g. vinyl chloride resins (see Division C3).ALSO:Tertiary phosphite esters obtainable by reacting tris (2-chloropropyl) phosphite with a mono- or polyhydric alcohol having a higher boiling point than 2-chloropropanol or by reacting tris (2-chlorobutyl) phosphite with a mono- or polyhydric alcohol having a higher boilding point than 2-chloro-butanol (see Division C2) are useful as stabilizers and plasticizers for vinyl chloride resins. The tertiary phosphite esters include cyclic phosphites having the general formulae: <FORM:0944726/C3/1> and <FORM:0944726/C3/2> wherein R1, R2, R3, R4, R5 and R6 are hydrogen or C1-C4 alkyl groups and n is 0 or 1.

Filed: 1971-01-15
Abstract: 1306912 Modulating light PPG INDUSTRIES Inc 15 Jan 1971 [19 Jan 1970] 2030/71 Heading H4F In a liquid crystal electro-optic cell, at least one of the electrodes comprises a transparent conductive cathodic sputtered metal oxide film deposited on a transparent substrate. Cathodic sputtering occurs when a glow discharge is maintained between an anode and cathode in an atmosphere of chemically reactive gas (such as oxygen) so that cathode metal is deposited as an (oxide) layer on the anode or another adjacent member. In the present case the metal may be In, Sn, Sb, Cd, or mixtures thereof. A dopant of higher valency state included in the metal gives an oxide layer of higher conductivity, and addition of metal of a higher atomic weight enhances the sputtering rate, as does the presence of an inert gas such as a noble gas in the atmosphere. As particularly described, the liquid crystal exhibits dynamic scattering, and the other electrode may be identical to the first, or opaque, or reflective. Parts of the sputtered metal oxide film may be removed, e.g. by etching, grinding or removal of previously applied resist material, to give a patterned electrode, for example a predetermined shape or a grid, lattice or mosaic, with elements which are independently charged by a scanning signal.
