Title: External rear-viewing observation mirrors for vehicles
IPC: B60R1/06
Filed: 1964-06-12
Abstract: 1,024,998. Rear-view mirrors. H. P. SMALLBONE. Oct. 21, 1964 [June 12, 1964], No. 24442/64. Addition to 828,175. Heading B7J. An external rear-view mirror, Fig. 1, comprises a reflector 21 rotatable about the central axis normal to the reflector surface by means of a gearwheel 15 rotatable by a cable 25 extending to the interior of the vehicle. The reflector is carried in a casing 20 under the urge of a spring 22, the casing being connected through a free-wheel with a spindle 14 rotatably mounted in a bearing 12 carried in a housing 10. The latter is secured to the vehicle wing through a universal joint device 11. The gearwheel is rotatable on a pin 16 carried between parts 12a of the bearing and the teeth thereon mesh with teeth 14a on the spindle 14. The cable 25 is secured to the gear-wheel by a pin 24, Fig. 2 (not shown), and when the cable is pulled the reflector is rotated through the free-wheel. On release of the cable, the reflector continues to rotate under its own inertia but the free-wheel permits the gear-wheel and spindle 14 to return to their normal positions by the action of a spring 26, Fig. 2 (not shown), secured to the gear-wheel and to a horn 27 on the bearing 12. In another embodiment pulling of the cable causes the gear-wheel to rotate and wind up a spring concentric with the pin carrying the gear-wheel, but drive is not then transmitted to the reflector spindle. On release of the cable the spring unwinds to drive the spindle through the free-wheel device. In alternative embodiments, the gear-wheel may be replaced by a pivoted gear quadrant or by a slidable rack or the cable may be wound on to a small diameter drum coaxial with the reflector and connected thereto through a freewheel. The housing of the rear-view mirror may carry an L-section rotably adjustable ring at its open end the ring supporting a wiper blade to engage the reflector.

Title: Low temperature sulfonation process
IPC: C07C309/62
Filed: 1956-08-10
Abstract: Oil-soluble sulphonates are prepared by contacting a solution of a petroleum hydrocarbon oil in liquid sulphur dioxide at a temperature not exceeding 0 DEG  C. with a sulphonating agent in a single treating step, removing the sulphur dioxide, neutralizing the resulting mixture in the presence of a hydrophilic solvent, and countercurrently extracting the total product emulsion at a temperature above 50 DEG  C. with an organic solvent to produce an extract phase containing oil-soluble sulphonates of high quality. The sulphonating agents include 100% sulphuric acid, oleum and stabilized liquid anhydrous SO3, 10-25 volume per cent oleum being preferred. For maximum yields of oilsoluble sulphonate, 3 to 7 mols. of SO3 per mol. of sulphonatable hydrocarbon are used when sulphuric acids or oleum are employed, and 1.5 mols. to 3.5 mols. of SO3 per mol. of sulphonatable hydrocarbon when gaseous or liquid SO3 is used.  The reaction temperature is not greater than 0 DEG , preferably not greater than -10 DEG  C.  The sulphonating agent, either alone or dissolved in liquid SO2, is added to the hydrocarbon and not the reverse order of addition.  The reaction vessel may be a highspeed type of turbo or sheer mixer comprising internal or external heat exchanger means.  Neutralization of the reaction mixture may be effected with a basic alkali metal or alkaline earth metal compound, usually aqueous or solid caustic soda or soda ash, and the hydrophilic solvent is preferably a C1 to C4 alcohol.  The temperature should be maintained at 0 DEG  to + 10 DEG  C. until the mass is neutralized and then the temperature can be allowed to rise to room temperature.  The quantity of alcohol used may vary from 50 to 150% based on the volume of feedstock. The solvent used for the countercurrent extraction of the neutralized mass is preferably a hydrophobic solvent such as benzene, xylenes and halogenated hydrocarbons.  The oil-soluble sulphonates make excellent engine detergents and rust preventives. Specification 670,620 is referred to.

Abstract: 1,186,214. Needled laminate. BREVETEX S.A. 26 May, 1967 [27 May, 1966], No. 24587/67. Heading B5N. [Also in Division D1] A method of forming a textile sheet material comprises making a plurality of incisions in a fibrillatable foil at an angle to the direction of fibrillation, placing a layer of material e.g. a loose fibrous web, adjacent to the foil and needling the composite to fibrillate the foil. The fibrillatable foil may be of polypropylene or may have a vinyl acetate/ethylene copolymer added. The loose fibrous web is preferably of polypropylene fibres. In a preferred embodiment, the fibrillatable film with incisions therein is passed to a cross-lapping device where a fleece of fibres is laid on the foil. The composite then passes to a needling apparatus which pierces the foil and pushes some of the fibres therethrough, the foil being thus partially fibrillated. The needled structure is then reversed and passed to a further needling apparatus which further fibrillates the foil and pushes the fibrils back into the structure so that the fleece fibres and the fibrils are intermingled. In a further embodiment, a fibrillatable foil is placed on either side of a layer of dry free leaves or paper.

Title: Method of and apparatus for hoisting and lowering loads
Inventor: GREPE FREDERICK YORKE
IPC: B66C13/26
Filed: 1962-06-27
Abstract: 999,314. Control of two A.C. motors. CANADIAN CONTROLLERS Ltd. June 27, 1962, No. 24711/62. Heading H2J. Relates to a control system for a hoist in which two A.C. motors are coupled to a load, and each motor has variable resistance in its rotor circuit. In the first hoisting-position of a drum controller, main motor 1 is connected to supply main 3, 4, 5, and a friction brake B is released after the motor is energized. The stator of auxiliary motor 6 is supplied with direct-current to exert a braking torque against the driving action of the main motor. The main motor has high secondary resistance, while that of the auxiliary is low in value. In the second hoisting-position the driving torque is increased and the braking torque reduced by rotor control. The auxiliary motor is connected to assist in hoisting the load in the third hoisting-position of the drum controller. Thereafter the load is lifted at high speeds, the rotor resistances being reduced in steps under the control of timing contactors. If an overhoist limit switch is operated, when the controller is in the first or second hoisting-position, the braking torque exerted by the auxiliary motor will assist the friction brake in stopping the load. The limit switch contacts may be connected either in a contactor circuit or directly in the motor circuit. In the first lowering-position of the controller, the secondary circuit of the main motor is connected to energize the stator with direct-current in addition to the current derived from rectifier 95. The auxiliary motor is idle at this time. Thereafter, the rotor resistance of the main motor is increased and the auxiliary motor is connected to drive the load downward. Further acceleration is provided by reducing the rotor resistance of the auxiliary motor, and then connecting the main motor to assist the downward drive. The stator of the auxiliary motor may be supplied with direct-current for braking in the "off" position of the drum controller.

An erasing device for use in erasing typewritten matter comprises an eraser member 15 mounted on the end of a rotatable spindle 5, and a resiliently displaceable support 16 extending beyond the eraser member 15 and adapted to engage a typewriter platen to provide a yielding support and guard for the erasing device. The means for rotating the spindle 5 includes parts 2 and 7 having co-acting coarse screw-threads so that longitudinal movement of one part parallel with the axis of the spindle 5 produces rotation of the spindle. In an alternative embodiment (Figs. 4 and 5), the resiliently displaceable support comprises a two-toed foot (37), the eraser member passing between the toes to contact the paper. The spindle carries a spur gear (32) which is rotated by longitudinal movement of a part (44) carrying a rack (48), at right angles to the axis of the spindle. In a further embodiment (Fig. 6), the arrangement of the eraser member and resiliently displaceable support is similar to that of Fig. 1. The spindle carries a spur gear (53) which is driven by a rack (67). The eraser member, which is replaceable, may be of an abrasive nature similar to glass or sandpaper or emery-cloth, or may be formed with very fine cutting edges. The erasing device may be pivotally linked to a bracket slidable along the bail-bar of a typewriter, or may be built into the typewriter and operated by its own key.

Abstract: 1400894 Capacitors SIEMENS AG 24 May 1973 [1 Sept 1972] 24922/73 Heading HIM A method of encapsulating an electrical component having lead wires connected to end contact faces of the component comprises wrapping the component with a metal foil, or metallized synthetic resin foil with the metallization outwards, in such manner that no electrical contact is formed between the end contact faces, placing the component in a reservoir containing synthetic resin powder suspended in a gaseous medium and maintained in turbulent motion, and heating the component indirectly by induction using h.f. current so as to fuse or sinter resin powder deposited on the component. As shown capacitor roll 9 has metal or metallized plastics foil 4 wrapped round so as to leave gaps 5 between it and Schoop coatings 2, the width of gaps 5 being such that these can be bridged by the encapsulating resin 8. Gap 5 may alternatively be left at one end only (Fig. 5, not shown). In a stacked capacitor (Figs. 1, 2, not shown) foil 4 may be attached to sides of the capacitor instead of wrapping it around the two faces with no metal covering also being coated with resin powder because of inductive heating of electrode edges extending to these faces. Hardening and smoothing of the encapsulating resin may also be effected by inductive heating.

Abstract: 338,533. Allgemeine Elektricitõts- Ges. Aug. 1, 1929, [Convention date]. Locating faults; phase differences and power factors, measuring. - Apparatus for testing the compensation for earth leakage currents produced by means of earth leakage coils comprises an earth leakage coil b connected to the winding a of a transformer and arranged in series with an alternating generator c and the current coil of a power factor indicator e, the voltage coil of which is excited by the generator. A frequency meter or a speedof-rotation meter f measures the frequency of the current produced by the generator. The speed of the generator is adjusted until the instrument e indicates a power factor of unity, at which point resonance is set up in the oscillatory circuit consisting of the inductance of the coil b and the capacity of the means, and the frequency produced in the generator is equal to the resonance frequency of the oscillatory circuit. The resonance frequency is inversely proportional to the square root of the degree of compensation, so that the meter f indicates on a suitable scale the degree of compensation directly. In another form the generator is of constant frequency and is in parallel with the coil b and the capacity of the mains with a transformer between. The current and voltage of the generator are supplied to the current and voltage coils of a measuring instrument. In another form, the source of current is a transformer, the secondary of which is in series with the coil b and in parallel with a reactance meter.
