Abstract: 958,664. Switches held set and freed mechanically; electromagnetic switches. TELEPHONE MANUFACTURING CO. Ltd. July 4, 1961 [July 6, 1960], No. 42180/63. Divided out of 958,663. Heading H2B. An operating member, e.g. the push-button of a switch, actuated to different positions by successive operations thereof, is locked in one of the positions by a relatively-movable pin and closed track, the latter including a ramp and a step providing relative movement between the pin and track in a direc tion transverse to the first-mentioned movement. One form of the track is shown in Fig. 2, the pin 6 being so mounted as to be urged down on to the track and to the left. The step 10 thus prevents the pin from moving into the left-hand leg 9 of the track when moved upwards from the position shown. The track may be carried by the pushbutton and the pin by the fixed part of the switch, or vice versa, and in the first case the track may be used as a cam to actuate the switch contacts. An indicator lamp may be mounted on the fixed part and within the pushbutton which has a transparent cap. The button may be operated by a pulsed electromagnet.

Title: Improvements in or relating to the treatment of shaped articles comprising elastomeric polymers
IPC: D06M23/14
Filed: 1959-12-15
Abstract: The process of the parent Specification (wherein yarns &c. of elastomeric linear polymers are heat treated at temperatures between 80 DEG C. and the melting point of the polymer and then cooled) is modified in that a shaped elastic article such as a filament or film comprising a linear synthetic segmented elastomeric polymer has one or both of its dimensions permanently altered by exposing the article, while deformed in at least one direction by an amount less than its breaking elongation, to a temperature of at least 100 DEG C., preferably between 100 DEG C. and about 180 DEG C., and cooling the article to a temperature below 70 DEG C. while under deformation. The deformation is generally produced by stretching, but deformation by compression, such as calendering, may be employed.  "Segmented elastomers" are defined as comprising segments of a crystalline polymer having a melting point above 200 DEG C. alternating with segments of an amorphous polymer having a melting point below 50 DEG C.  The crystalline polymer may be a urea, urethane, amide or bis-ureylene polymer, or a polyester.  The amorphous polymer may be a polyester, a polyether, or a polyhydrocarbon.  The heating period should generally be not less than about 5 minutes, 15 to 60 minutes being preferred.  At 100 DEG  to 125 DEG C. the period is preferably 30 to 60 minutes.  At the lower temperatures heating may be continued for up to 70 hours.  At 125 DEG  to 150 DEG C. the heating period is preferably 10 to 30 minutes.  The filament or film may be stretched from about 10 to 500% or more while being heated.  It may be stretched at room temperature or at an elevated temperature, before or simultaneously with the heating step.  If a film, sheet or fabric is being treated, it may be stretched in both the lateral and the longitudinal directions before the heat treatment.  The article is preferably prevented from retracting at all throughout the heating period or while the article is being cooled to below 70 DEG C. and preferably to room temperature.  In reducing the denier of filaments to a range within 10 to 100 denier by stretching, successive treatments according to the invention may be employed, with the filaments being drawn to a point below their breaking elongation prior to each treatment.  In an example, elastic filaments obtained by wet spinning the reaction product of polytetramethylene ether glycol and 2,4-tolylene diisocyanate (which product has in turn been reacted with p,p1-methylene diphenyl diisocyanate) into ethylene diamine are relaxed in boiling water for 30 minutes, stretched 34% and while stretched are heated in boiling water for 60 minutes and then cooled to room temperature while under tension.  The invention enables the denier of elastic yarns to be reduced without destroying their elastic character.  Specification 779,054 and U.S.A. Specifications 2,813,775 and 2,813,776 also are referred to.

[Also in Division G1] A bearing assembly for a gyroscope has a fluid bearing which operates during normal conditions and a ball-bearing, serving as a combined radial and thrust bearing, which comes into operation when the fluid bearing becomes inoperative. The fluid bearing comprises two co-operating cup-shaped components 70, 110 which are carried by an extension 46 of a head 42 and by a gimbal 24 respectively. The component 70 consists of a part 72, Fig. 2, which, having external screw-threads at 84, is secured to a part 74; Fig. 4, having internal screw-threads at 102. The component 110 is secured to the gimbal 24 by screws 111 and is located by a pin 115 thereof which is received by a recess 116 in the gimbal. The ball-bearing 60 has its inner race 62 mounted on the extension 46 of the head 42 and its outer race 64 attached to the component 70, thus the latter is connected to the extension 46. In use, compressed air is supplied by a conduit 54 to a bore 52 in the extension 46 of the head 42 and is conveyed to a chamber 106 in the component 70 from where it is passed through spaced openings 92, 98 therein, into a space 126 between the components 70 and 110. The air is allowed to escape through the annular space between the components 70 and 110 and through openings 120 in the component 110. A quantity of air passes through the ballbearings 60 and serves to eliminate radial and axial play. In a modification, the conduit 54 is out of alignment with the axis of the gimbal 24 and the bore 52 does not pass through the head 42.

Title: Improvements in or relating to the production of valuable gases
Inventor: GOULD GEORGE DOUGLAS
Filed: 1965-10-08
Abstract: Fuel gas is made from a hydrocarbon distillate by a two-stage process, namely: catalytically hydrocracking the distillate in the absence of steam in one zone and gasifying part at least of the products of the hydrocracking in a second zone.  The gasification step may comprise a partial oxidation process (not described) or continuous steam reforming with a nickel catalyst and may comprise two reformers in parallel, see Fig. 1 (not shown) one dealing with the lighter fractions of the hydrocracking to produce a CH4-rich gas, and one the heavier fractions to produce an H2-rich gas.  The first reformer may be replaced by a thermal hydrocracker, see Fig. 2 (not shown), and the CH4-and H2-rich gases may be mixed together, if desired with an external gas, e.g. LPG, natural gas, refinery gas or tail gas.  The flow diagrams (Figs. 1, 2) make clear the complete process, which includes purification, recycling of H2 to the first (hydrocracking) zone and recycling of C11 + fractions to the first zone.  The preferred hydrocracking catalyst is silica-alumina with one or more of Group VI and Group VIII metals or their oxides, sulphides and selenides, other supports being mentioned.  Preferred feedstocks are those boiling from 200 DEG  to 650 DEG  F., and products include olefins and benzol. Five specific examples are described.

[Also in Division H4] A power-distribution device comprises an array or arrays of probes arranged in a cross sectional plane of a waveguide, the probes in each array being spaced by a distance equal to the width of the guide divided by the number of probes. Thus (Figs. 9, 10, not shown) an array of two probes (2 1 , 2 2 ) may be spaced by half a waveguide width and respectively arranged in a waveguide having arcuate walls (10, 11) or a waveguide having a part-cylindrical short-circuiting wall (16). In the modification of Fig. 6, two arrays of two probes 2 1,  2 3  and 2 2 , 2 4  are arranged in a rectangular waveguide I of width a. It can be shown that the probes remain matched to the waveguide whatever their transverse position therein, providing the above-defined spacing is preserved. Thus, the probes shown in Figs. 6, 9, 10 may form part of a linear or circular array (e.g. the array 7, Fig. 13, not shown) which is continuously moved or rotated in such a manner that groups of probes are successively coupled with the waveguide. Slots are provided in the waveguide walls to allow such movement. Modifications are described in which the probes extend from opposite broad walls of the waveguide and in which they extend across the whole width of the guide. A method of matching the probes is described in which the arcuate end wall 16 has a section of castellated configuration in a plane parallel to the probes.
