Title: Improvements in or relating to electric insulators
IPC: H01B17/20
Filed: 1932-11-02
Abstract: 409,694. Insulators. BULLERS, Ltd., and PERRINS, G., 6, Laurence Pountney Hill, London. Nov. 2, 1932, No. 30920. [Class 36.] To prevent deposition of dirt on the interior surface of an insulator of the pin type, a shield formed wholly or partly of sheet metal, preferably zinc, is carried by either the pin or the outer shed of the insulator and is so formed as to bridge the greater part of the space between the pin and the edge of the shed and to leave a small annular gap between the shield and either the shed or the pin. The shield is preferably so formed that moisture collecting on its outer surface drips clear of the pin. Fig. 1 shows an annular shield 6 of U-section carried by the outer shed 4 of an insulator, the outer wall of the shield having slots 7 to enable the shield to be sprung into position. In a modified construction the shield 10 is shaped as shown in Fig. 3 and may have a beaded edge 13 which is sprung into a groove 12 in the shed 4. Fig. 5 shows a cup-shaped shield 17 carried by the insulator pin 1 and having perforations 20 to allow escape of moisture. The wall of the cup may extend outside the shed 4, as shown, or may project into the space between the sheds 3, 4. In another construction, the part of the shield which engages the pin or the shed is formed of metal whilst the other part is of insulating material, such as porcelain.

Title: Improvements in or relating to sound reproducers
IPC: H04R9/12
Filed: 1930-10-16
Abstract: 363,449. Gramophone pick-ups. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Keller, A. C. ; 197th Street, New York, U.S.A.) Oct. 16, 1930, No. 30996. Convention date, Oct. 24, 1929. [Class 40 (iv).] The moving coil 13 of an electrical sound reproducer for hill-and-dale records is rigidly attached to a substantially coaxial stylus 15 and is adapted to be moved axially thereby through a radial magnetic field. In one form, a U-shaped magnet 1 is mounted in a casing 2 and has polepieces 4, 5 so shaped and positioned that a detachable central piece 6 of the pole 5 projects into an opening in the polepiece 4 to form an air gap 8 in which the coil 13 is situated. The coil 13 may consist of about 40 turns of fine ribbon preferably aluminium wire wound on a hard rubber former 14 carrying the stylus 15. The ends of the coil 13 are connected to terminals 18. The moving system is elastically supported on two pieces of spring steel wire 19 which also serve to hold the stylus in contact with the record. The air gap may be of any desired shape and a brass bracket 9 maintains the alignment of the polepieces. The reproducer is so designed that the maximum mechanical impedance in dynes per centimetre-per-second measured at the stylus point. at any frequency within the range of frequencies to be reproduced multiplied by the maximum velocity in centimetres per second to be attained by the stylus point at this frequency is less than the stiffness in dynes per centimetre multiplied by the deflection or strain in centimetres of the elastic support when the stylus is resting upon the record groove normally but in the static condition; and the mass of the coil and stylus assembly and the stiffness of the elastic support are so mutually proportioned that these form a resonant mechanical system having a natural frequency at about the geometric mean of the highest and lowest frequencies to be reproduced. The Specification contains an analytical mathematical consideration of the manner in which the design may be varied to suit requirements and conditions. Specific values are given and claimed in the Specification for the dimensions and mass of the movable parts. The coil may be damped by using oil around the coil.

Title: Process for the production of lower boiling hydrocarbons by destructive hydrogenation of liquid carbonaceous materials of higher boiling point range
IPC: C10G47/00
Filed: 1934-10-30
Abstract: Lower boiling hydrocarbons, e.g. motor fuels, kerosene, &c., are obtained from liquid carbonaceous materials having an upper boiling limit above 350 DEG  C., by separating from the initial material a residue of pitch, resin, &c., which would impair catalyst activity, by a distillation not leading to any substantial decomposition, condensing the distillate and then passing it together with hydrogen or a gas containing substantial amounts of free hydrogen, under pressure and under splitting conditions over stationary catalysts. The distillation may be carried out in the presence of gases or vapours and is preferably continued under reduced pressure.  Prior to destructive hydrogenation, the product may be refined with sulphuric acid, aluminium chloride, bleaching earth, &c.  Destructive hydrogenation is preferably effected in the vapour phase, at a temperature of 350--550 DEG  C., and preferably 380--450 DEG  C., this pressure being at least 20, and up to 1000 atmospheres, and the amount of hydrogen being 100 up to 6000 cubic metres per ton. Suitable catalysts are metals of groups 2--8 of the periodic table, e.g. molybdenum, chromium, tungsten, vanadium, and, in particular, their oxides, sulphides and halides.  The catalyst may be supported on carriers, e.g. active carbon, active silica, alumina, de-ashed brown coal small coke or brown coal small coke pretreated with acids or acid substances.  In an example, benzine is removed from asphalt base mineral oil by distillation and the distillation is continued up to 350 DEG  C., under normal pressure and then, whilst adding water vapour, under a vacuum of 10--15 mm. mercury.  The distillate is heated to 410 DEG  C. together with hydrogen under a pressure of 250 atmospheres in a tubular preheater and led through a reaction space filled with pills of tungsten disulphide.  The vapours are fractionally condensed and fractions boiling above 200 DEG  C., are re-cycled.  The product, consisting of benzine, is washed with dilute caustic soda before coming into contact with the air.  The residue from the initial distillation is mixed with acid-treated brown coal small coke containing 2 per cent of molybdic acid and treated in liquid phase with hydrogen under a pressure of 250 atmospheres at 470 DEG  C.  The product comprises 10 per cent of constituents boiling up to 180 DEG  C., and 48 per cent up to 325 DEG  C., which product is worked up with further initial material.  Specifications 331,199, [Class 32], 345,282, 348,834, and 359,993 are referred to.

Title: Means for laterally controlling aircraft
IPC: B64C9/28
Filed: 1925-12-09
Abstract: 263,290. Page, F. H., and Handley Page, Ltd. Dec. 9, 1925. Balancing. - For laterally controlling aircraft provided with slots at the ends of the wings, the mechanism for opening or closing the slot at each side of the machine is operatively connected to the aileron on the opposite side. The control means are particularly ap plicable to machines in which the aileron which is being raised turns through a greater angle than the one that is being depreseed, so that the slot on the side of the machine where the aileron is depressed is opened while the other one remains substantially closed. Fig. 2 shows an aileron A on the starboard side of the machine connected by a rod D<1> to a three-armed lever E, interconnected bv rods or cables to a similar three-armed lever G on the port side. This lever G is connected by a rod H to a bell-crank J coupled by a link K to one of two links L. L' which carry an arm B<2> attached to a small plane B<1>. Small movements of the aileron A move the link K across the dead centre of the bell-crank J and the plane B<1> is not appreciably moved, but larger movements thrust out the plane B<1> and open a slot between it and the main plane. A modification is described in which the bell-cranks J are dispensed with and the cable circuits interconnecting the levers E, G are connected to two rods F<2>, Fig. 8, which have pins F' engaged by cam slots M in two plates N mounted on the shaft of a control lever P so that the aileron on one or other side of the machine is raised, and the interconnected slot mechanism opened, while the other aileron and slot mechanism remains stationary.
