Title: Improvements in a thermally responsive control device
Inventor: HEWITT JOHN CECIL
IPC: G05D23/19
Filed: 1958-04-24
Abstract: 885,502. Valves. ROBERTSHAW-FULTON CONTROLS CO. April 24, 1958 [July 22, 1957], No. 13047/58. Class 135. [Also in Group XIII] A control device comprises the combination of a thermo-electric magnetically re-set safety valve with a control valve 54, Fig. 4, actuated through a snap-acting device 64 either directly or through a crank 102 by a thermal-electric motor having a thermally expansible member 84 heated by an insulated resistance wire 86 in series with a thermostat. Gas for space or furnace heating passes the thermo-electric safety valve in casing 70 to an adjusting cock 24 containing a rotatable adjusting sleeve valve 40 and then past valve 54. The member 84 may be a sleeve, a solid rod or a bored rod adjustably connected to the casing at 106. The member 84 may be provided with ballast means to prevent overheating and straining the snapacting mechanism e.g. as shown in Fig. 10 by having an inner sleeve 488 engaging the adjusting screw 408 and which expands during long periods of heating of the element 84 to reduce its overall expansion. In other embodiments an aluminium wire extends through the bored rod to increase the rate of heat transfer to the surrounding structure or a dispersoid of heatconducting material, e.g. silver lacquer paste, may be introduced between the ends of the member 84 and the surrounding structure. The electrical ballast means may be formed by using a heating element whose resistance increases with temperature.

Patent GB-623838-A (GB)
Title: Improvements in or relating to the production of dihydrodypnone
IPC: C07C29/143
Filed: 1947-05-15
Abstract: Dihydrodypnone, C6H5.CH(CH3).CH2.CO C6H5, and dihydrodypnol, C6H5.CH(CH3).CH2.CHOH.C6H5, are useful as plasticizers for cellulose acetate, polyvinyl chloride, polystyrene and polyvinyl acetate, alone or in association with other plasticizers which confer special properties such as the non-inflammable properties conferred by tricresyl phosphate.ALSO:Dihydrodypnone, C6H5.CH(CH3).CH2.CO.C6H5, is manufactured by heating acetophenone at 160-250 DEG  C. in the presence of a catalyst capable of promoting both the condensation of a ketone and the hydrogenation of the resulting product, and introducing hydrogen at a sufficient partial pressure to convert dypnone to dihydrodypnone as fast as it is formed.  Advantageously a rapid current of hydrogen is passed at atmospheric pressure and the temperature is initially 180-190 DEG  C. and may later be raised to about 250 DEG  C.  Suitable catalysts are nickel and copper or compounds thereof easily connected to the metal on heating, e.g. the product produced by the decomposition of nickel formate in a high-boiling sulphur-free hydrocarbon.  When the presence of polymerization products of dypnone is not detrimental, the process may be modified by heating the acetophenone in the presence of the catalyst without the introduction of hydrogen and then hydrogenating the dypnone so produced.  An example of the single stage process is given.  Dihydrodypnol (1 - hydroxy - 1 : 3 - diphenylbutane) is manufactured by reducing dihydrodypnone with or without isolation from the reaction mixture obtained as above.  Thus the condensation and hydrogenation of acetophenone may be carried on until the formation of dihydrodypnone has reached a maximum, the temperature then reduced to 70-100 DEG  C. and the introduction of hydrogen continued.  Alternatively, the dihydrodypnone is isolated and reduced, e.g. with hydrogen under super-atmospheric pressure at 70-100 DEG  C. or by the action of an alcohol such as isopropyl alcohol and an aluminium alkoxide such as aluminium isopropoxide.

Title: Improvements in or relating to telecommunication switching systems
Inventor: HILLEN CECIL FREDERICK JOHN
IPC: H04Q3/555
Filed: 1965-03-29
Abstract: 1,146,686. Automatic exchange systems. H. M. POSTMASTER GENERAL. 24 March, 1966 [29 March, 1965], No. 13223/65. Heading H4K. An array of switches, each having a number of outlets with access to a number of inlets, has the inlets multipled according to a grading scheme in which each multiple connects corresponding inlets of a unique combination of switches. The grading scheme is shown in Fig. 1 as applied to a 5 x 5 array of 5 x 5 relay or cross-bar switches. The sixth row A6 to E6 is to be ignored for the moment. The horizontals of each switch serve a corresponding group of five subscribers; the array serving 125 subscribers in total. The grading is effected by staggering the connections between verticals of adjacent rows; the xth vertical of any switch in one row being connected to the corresponding vertical of the (x-p)th switch in advance in the adjacent lower row; p being an integer and the switches of a row being taken cyclically. Such a grading scheme repeats itself every 5 rows. Additional rows such as A6 to E6 may be added but expansion of the array is preferably made by wiring together corresponding multiples of identical 5 x 5 arrays. The grading scheme is also applied to 7 x 7 switches in a 7 x 7 array and 9 x 9 switches in a 9 x 9 array.

IPC: C08F6/02
Filed: 1958-04-29
Abstract: Catalyst residues are removed from hydrocarbon polymers obtained by polymerization of hydrocarbons using a Ziegler catalyst at below 100 atmospheres, by dissolving an alcohol in a water immiscible liquid in which the crude polymer is, or is subsequently, suspended and then creating an aqueous alcohol disperse phase in the suspension liquid by adding water or water and alcohol and separating this phase from the suspension. Specified polymers are those of ethylene, propylene, butylene and styrene while methanol, ethanol, isopropanol, butanol, cyclohexanol, cyclopentanol and benzyl alcohol are specified alcohols.  Waterimmiscible liquids specified are pentane, hexane, cyclohexane, heptane, kerosene and tetrafluorodichloroethane. The aqueous alcohol phase is preferably from 10 to 50% by volume of the suspension liquid.  Further catalyst residues may be removed in at least one further stage in which the alcohol added need not be the same as that added in the first stage. Specification 808,162 is disclaimed.

Abstract: 182,996. Stone & Co., Ltd., J., and Darker, A. H. May 13, 1921. Centrifugal actuation; actuation by reversal of rotary motion.-Relates to dynamo pole-changers for train-lighting sets actuated by a governor which, during the initial movement in either direction, operates frictional means for polechanging and after, as the speed increases, permits closing the switch and disengages the frictional means of the kind described in Specification 7468/10. The armature bearing housing g carries a contact board i and brackets f fitted with pivot pins k carrying the steel or phosphor-bronze spring switch arm l and rocking arms o. The arms o, l are so mounted as to move together about the pivot k. The outer ends of the arms o slidingly carry the friction blocks w which engage, at low speeds, the disc u of the governor. The board i carries contacts t, t<2>, t<3>, t<4>, and the governor constrains the arms l to move to contact with opposite pairs of contacts t', t' or t<2>, t<3> according to the direction of rotation, contact only being effected when the speed is high enough to move the disc u along the shaft out of engagement with the blocks w. The board i may also carry a third switch arm y which the governor, on retracting, allows to move out of contact with its contact plate to cut resistance into the circuit. Fig. 5 illustrates the manner of applying the switch to a lighting circuit. In a modification, Figs. 8 and 9, the arms l<1> are carried by a rocker 2 and themselves carry the blocks w<1>. The operation is the same as that of the first-described modification, but the arms l<1> are adapted to bridge two pairs of contacts 4, 5 and 5<a>, 6<a> or 5, 6 .and 4<a>, 5<a> according to the direction of rotation.

The walls of the socket 11 are split at 12 to add resilience, and a helical spring or rubber pad may be mounted in the end of the socket to give axial resilience. A tubular packing, e.g. of polythene, may be inserted between the socket 11 and the shell, and a shank on the packing may protrude out of the cap 151 to protect the contact maker. Axially resilient sockets may be mounted on one bar and non-resilient sockets on the other, or the two kinds of socket may be disposed alternately on each bar, or an auxiliary bar carrying non-resilient sockets may be mounted on one of the bars through the intermediary of sockets containing springs, or pads.
