Title: Striking mechanism for clocks
IPC: G04C21/08
Filed: 1927-09-19
Abstract: 277,963. Milde Fils et Cie, C., and Gosselin, J. H. Sept. 27, 1926, [Convention date]. Brush-holders; armatures. - Striking mechanism of the rack type for striking the hours and half-hours is actuated bv an electric motor which runs at a constant speed and is fed with current only at the hours and half-hours by means of contacts either constituted by the commutator brushes or directly connected therewith. To cause the brushes 27, 31, Fig. 2. to press evenly on the commutator the brush 31 carries a weight 49 and a spring 46 which presses against an adjustable screw 47 on the brush 27. Since the motor is a small one and only a small number of poles and coils are used, the armature would stop in one of several positions of equilibrium, and a supplementary torque would be necessary to restart it. This is avoided to some extent by fitting frictionally over the cylindrical armature a comparatively thin sleeve of magnetic metal slightly longer than the armature.

Title: Improvements in and relating to synthetic resins
IPC: C08G8/30
Filed: 1947-09-10
Abstract: A process for the manufacture of an oil-reactive resin comprises reacting by heating a terpene-phenol resin, a reactive phenol having more than two of the o and p positions unoccupied and formaldehyde or a substance which yields formaldehyde under the conditions of the reaction in the presence of an alkaline catalyst.  The reaction is preferably carried out in solution in propanol, n-butanol or isobutanol, which may be diluted with benzol, toluol, or xylol.  The solvent may be left in the product. The terpene-phenol resins are prepared by condensing terpene hydrocarbons and phenols in the presence of a Friedel-Crafts catalyst, e.g. boron tri-fluoride. Examples describe (1) reacting together terpene-phenol resin, phenol, paraformaldehyde, NaOH, in butanol solution; (2) a process as in (1) but using cresylic acid; (3) using an ammonia catalyst; (4) a process as (1), using ammonia as catalyst and heating the product to remove volatile matter; (5) a process as (1) using ammonia as catalyst, dissolving the product in tung oil at 180 DEG  C., and thinning with xylol to form a varnish.  Titanium dioxide pigment and cobalt and lead driers are added.

Abstract: 847,179. Semi-conductor rectifiers. WESTING- HOUSE ELECTRIC CORPORATION. Aug. 1, 1958 [Aug. 9, 1957], No. 24847/58. Class 37. A rectifier device as shown in Fig. 2 comprises a semi-conductor rectifier cell 1 soldered to a flat base 7 of any suitable material, preferably copper, by a solder, preferably of 95 % lead and 5 % indium, the base 7 is mounted within a substantially cup shaped member 8 with which it is preferably integral. The base 8 has a passageway 11 and tube 9 for evacuating the sealed enclosure. The base 8 is attached preferably by soldering with a 100% tin solder, to a heat dissipating means which may be water cooled or, as shown in Fig. 2, be a relatively massive cylindrical portion provided with radial cooling pins.

Title: Catalytic conversion of aromatic distillates
Inventor: JR JOHN WALTER SCOTT
IPC: C10G47/00
Filed: 1959-07-21
Abstract: High octane gasoline is produced by isocracking a hydrocarbon fraction having an aromatic content of at least 30% by volume, a basic nitrogen content of less than 25 p.p.m. and a 10-90% boiling range within the range 330 DEG -650 DEG F. in the presence of at least 2,000 SCF of hydrogen per barrel of feed and a catalyst having a hydrogenating component disposed on an active cracking support and having a severity factor of 0,1-2,0 at an average catalyst temperature of 300 DEG -750 DEG F. and at least 400 p.s.i.g.  The severity factor is defined as the ratio of volume per cent aromatics in the feed to that in the product minus 1 when employing a trimethylbenzene concentrate under standard conditions of 650 DEG F., 1200 p.s.i.g., 9,000 SCF hydrogen per barrel of feed and a LHSV of 2. Suitable supports are silica-aluminas containing 75-95% silica, e.g. one having a cat A activity of 46 and a surface area of 430 M2/g. The support may contain 0,1-30% of a group IB, IIB, VI or VIII metal or oxide or sulphide thereof, nickel sulphide being preferred.  The feed may be a naphtha, kerosene, gas oil or cycle oil of straight run origin or obtained by thermal or catalytic cracking of stocks obtained from petroleum, gilsonite, shale or coal tar, or a reformed fraction.  Nitrogen content may be reduced by hydrofining if necessary.  The feed is introduced as vapour and/or liquid according to conditions at a LHSV of 0,2-5.  The conversion is preferably maintained at a steady value of 20-70% and the hydrogen consumption at 1,000-2,000 SCF per barrel of converted feed.  Product boiling above 330 DEG  may be recycled to extinction.

Title: Improvements in carburettors
IPC: F02M9/06
Filed: 1953-09-10
Abstract: 761,367. Carburetters. LANCEFIELD S. S. Dec. 6, 1954 [Sept. 10, 1953], No. 25071/53. Class 7 (3). A carburetter comprises a throttle slide which is completely removed from the induction passage at full throttle and a tapered mixture control needle movable within the slide for example it is positioned substantially at the axis of the slide and means for causing relative movement between slide and needle whereby at low and medium powers the needle is still entered in the jet and therefore lies in the path of the air stream but at full throttle the needle is withdrawn from the jet and out of the air stream. As shown a throttle slide is operated by a cable 8 and a fuel needle 6 is operated by a cable 4. The cables as indicated by Fig. 3 are connected respectively to drums 10, 9. The lever 11 may be the lever of the accelerator pedal or a twist grip may be used instead of a pedal. The needle may move at twice the speed of the slide. By shaping the contours of the drums or by eccentrically mounting them it can be arranged that equal angular movements of the operating device may be arranged to cause a greater or less amount of cable movement at different parts of the movement of the operating device. The purpose is to get the needle clear at racing speeds and thus the control can be a normal one up to half power or a little higher whereafter further pedal movement may cause needle and slide speeds to differ. The needle holder 3 may have an adjustable needle grip. The slide and needle may each be moved by a Bowden cable rod or the like and the two cables or other operating devices coupled to a single operating member such as a pedal or twist grip by drums, cams or the like. Cables or like flexible members may wrap and unwrap round drums, cams or the like which are rotated by a single operating member such as a twist grip or a pedal. Specification 756,059 [Group XXXI] is referred to.

The composition may also contain an aqueous dispersion of an aminoplast, e.g. a urea- or melamine-formaldehyde resin.  Textile materials specified are those made of cellulose esters of low hydroxyl content, as described in Specifications 758,442 and 791,391, or of higher hydroxyl content, e.g. cellulose acetate of 53 to 55% acetyl content, nylon, polyethylene terephthalate, acrylonitrile homo- and co-polymers, vinyl chloride homo-and co-polymers, rayon, cotton and wool.  Examples are given.ALSO:A composition for treating textiles (see Groups IV (c) and VIII) comprises a mxiture of a siloxane containing Si-bonded hydrogen atoms and hydrocarbon radicals and a colloidal dispersion of silica.  Siloxanes disclosed are preferably liquid at room temperature and contain methyl hydrogenosiloxy units with or without dimethyl- or dihydrocarbonyl-siloxy units and may also contain trimethyl- and monomethyl-siloxy units.  The colloidal dispersion may be a silica sol as described in U.S.A. Specifications 2,244,325, 2,285,449, 2,285,477 and 2,375,738, and may contain spherical particles of diameter from 40 to 80 m m , or it may be a dispersion of the product made by burning SiCl4. The composition may be made by mixing an aqueous emulsion of the siloxane, containing an emulsifying agent, or a mixture of the siloxane and emulsifying agent, with an aqueous dispersion of the colloidal silica, preferably in amounts of 0.5 to 1 part of silica per part of siloxane.  Curing catalyst, e.g. the octoates and naphthenates of Zn, Sn, Pb, Al and Zr, and aqueous solutions or dispersions of aminoplasts, e.g. urea- and melamine-formaldehye resins may also be added.

The continuation boundary may be generally curved, but formed by small steps (26, Fig. 5, not shown), and it may include a strip section (27) to reduce the possibility of sparking.
