Abstract: 468,060. Road - traffic signals on vehicles. LLOYD, W. H. Sept. 26, 1935, No. 26618. [Class 118 (ii)] An electrically operated signalling-hand can be moved from a downward vertical to a horizontal and upward vertical position, can be turned, and can be swung to and fro and up and down. The circuits are controlled from the brake, accelerator and steering mechanism or from hand-operated switches. If one arm is raised to indicate a turn, the arm on the opposite side of the vehicle gives the '' come-on " sign. A compartmented casing indicator may also be provided. The arm may be an internally illuminated arm of the form shown. When the coil B, Fig. 2, is energized the hand moves to the position shown in Fig. 6 and if the circuit includes trip 23 the circuit of the coil B is interrupted to allow the arm to oscillate to give a slow-down signal. If the coil C receives current, the hand is turned (Figs. 7 and 8), and if coil B is now energized the turn signal (Fig. 7) is given. The energization of coils A and B together with C give the stop sign (Fig. 8). Coil D causes the hand to swing to give the " come-on " signal indicated in Fig. 9. Circuit arrangements are given in the Specification.

Abstract: 1,128,107. Cathode ray tubes. HITACHI Ltd. 15 June, 1966 [23 June, 1965], No. 26722/66. Heading H1D. In a scanning electron microscope, the secondary or reflected electrons emitted from the point of impact of the primary beam on the specimen are focused by a uniform magnetic field extending along the path of the incident beam from adjacent the final magnetic focusing lens of the microscope, and are thereafter deflected sideways from the path of the incident beam to a detector, either by a magnetic or by an electro-static field, whereby the final lens of the microscope may be disposed close to the specimen surface. The incident beam 38 passes through an aperture 37 in the curved solenoid 35, which extends into the focusing lens 31, 32, 34, and thereafter through an aperture 41 on to a specimen 39, both of which are adjustable from outside the tube. The emitted electrons are focused and deflected by solenoid 35, and are accelerated by grids 42 and 45 on to the detector 36, the signal from which modulates the intensity of a synchronously scanned cathode ray tube. In another embodiment (Fig. 5, not shown), the continuous curved solenoid 35 is replaced by a succession of spaced, angularly displaced short coils. In a further embodiment (Fig. 7, not shown), in which a straight solenoid (58) extends most of the way through the magnetic lens, the sideways deflection of the secondary electron beam is achieved by the use of a pair of inclined electrodes (60, 61) which are apertured to provide passage for the incident beam.

Filed: 1935-10-02
Abstract: Polyesters having a mean molecular weight exceeding 3000 are prepared by autocondensation of monocarboxylic acids having alcoholic groups in the presence of a carboxylic acid having dissociation constant greater than about 3 X 10-<5>.  The hydrocarboxylic acid is preferably of the formula <FORM:0456934/IV/1> wherein R may be either hydrogen or a hydrocarbon group such as methyl, butyl or phenyl, and either x or y may be 0 or any number so long as the total of x and y is not less than 5.  The reaction is preferably carried in an inert or reducing atmosphere such as nitrogen, hydrogen or carbon dioxide suitable catalysts include chloracetic, dichloracetic, fumaric, phthalic and adippic acids, it being preferable to a glycol such as octadecane-1 : 2-diol, or the glycols from cracked wax to the reaction mixture in order to maintain a 1 : 1 ratio of hydroxyl and carboxyl groups.  The product, which may be extracted by solvents such as ketones, alcohols, light hydrocarbons, chlorine compounds, ethers and sulphur dioxide, may be milled, forced through an oriface, worked in gears or cracked.  The products, which posses  oxidation inhibiting properties and which will act as sludge dispersers in lubricating oils, may be used alone or with other materials as coating or impregnating agents or as lubricants.  They may also be used as blending agents in fuels, lubricants, greases, paints, insulating oils, pulp oils, glycerides, textile oils, emulsions or soluble oils, as a compounding agent in plastics, resin, rubber and waxes, and added to lubricants in conjunction with dyes, sludge dispersers, thickeners, pour inhibitors, oxidation inhibitors, soaps, oiliness agents, extreme pressure lubricating agents, metallo-organic compounds, colloidal metal and graphite. In examples 12-hydroxy-stearic acid is subjected to auto condensation alone or in the presence of adipic acid with or without the addition octadecane-1: 12-dio.  The product prepared with the aid of adipic acid may be added to a coastal oil or linseed oil.
