Title: Magnetic cushion for intercommunicating door or vehicle suspension - uses repulsion between like poles of two magnets for suspension without physical contact
IPC: B61B13/08
Filed: 1968-06-04
Granted: 1981-08-14
Abstract: The repulsive forces between like poles of two magnets or between a magnet and a diamagnetic substance, which increase as the inverse square of the separation can be exploded in door catches to open as well as close the door and as a means of suspension, by analogy with air suspension, as a magnetic cushion. By using alloys and ceramics high remenance and stable magnets can be produced in all manner of shapes and the repulsive parts need no direct contact with each other. These properties are an advantage over traditional types of suspension such as leaf springs and tarsim bars which are subject to wear and ageing. Equally magnetic repulsion may be used to act as shock-absorbers or bumpers. The suspension may provide a replacement for air cushioned transport with a guide rail, using electro-magnets to replace the air compressor and providing adequate uniform periodic magnets along the rail. Together with linear motor propulsion it is possible to produce a new transport system without the complexity of wheels, suspension or brakes which is safe, quiet and comfortable.

Title: Prepns. contg. bismuth polygalacturon complex - for medical use
IPC: A61K9/16
Filed: 1967-09-04
Granted: 1971-07-12
Abstract: A bismuthpolygalacturon complex may be brought in medical application form by mixing moist hydrated bismuthpolygalacturon complex precipitated from an aqs. medium with a shielding colloid such as gelatine and making the mixture micro-disperse in a colloid mill. The mixture is then mixed with at least one other component and dried below 30 deg.C. The complexes are used in medicine as a covering-, absorbing-, neutralising- or anti-obstipating agent in gastro-interological complaints. The new preparations have much greater physiological activity than the known bismuthgalacturon complexes prepd. in the dry form.

Abstract: 1,054,531. Grinding. F. G. GÍTZ, and E. T. A#NON. April 9, 1965, No. 15183/65. Heading B3D. A method of precision grinding internal surfaces of cylinders comprises using a longitudinally displaceable grinding tool rotatable about its longitudinal axis, and stopping the rotation of the tool during reversal of its longitudinal displacement. In apparatus for carrying out the method, the tool is carried by a guide member 1, Fig. 1a (not shown), formed with spiral channels 10 which cross each other. The channels are engaged by spiral guide members 9 on guide sleeves 2, 3, Fig. 2a (not shown), the members running in opposite directions on the guide sleeves and engaging respective channels on the guide member. The sleeves are located in a fixed bush 4 and each sleeve is formed with three grooves 5 each of which has a camming surface 6 engaged by spring-pressed rollers 7 so that both sleeves can rotate in one and the same direction only. When the guide member is moved downwardly by axial pressure, the rollers in one sleeve prevent that sleeve from turning and the spiral guide members of that sleeve impart rotation in one direction to the guide member carrying the tool, the other sleeve rotating freely. When the guide member is raised, the rollers of the other sleeve prevent rotation of that sleeve so that its guide members impart rotation to the guide member in the opposite direction, the first sleeve rotating freely. As the direction of longitudinal travel of the guide member is reversed, both sleeves are freed for a short period so that the guide member does not rotate.

[Also in Division F2] A height adjustment device for each spring 23 of a railway vehicle bogie allows adjustment of body height to compensate for wheel wear. The device comprises coaxial substantially circular elements 27, 29, a wide rim on the upper surface of the lower element 27 being divided into equiangular sectors 39 each subdivided into equiangular subsectors 41, 43, 45 of different heights, and the lower surface of the upper element 29 having the same number of equiangularly spaced depending radial ribs 49 as there are sectors 39 on the lower element, the elements being rotatable one relative to the other to seat the ribs 49 on selected sets of subsectors 41, 43 or 45 to adjust the height of the device.

Abstract: 1,257,169. Control of motors. HONEYWELL Inc. 2 Dec., 1968 [28 Jan., 1968], No. 57147/68. Heading H2J. In a self-balancing bridge circuit for energizing a continuously reversible motor 136, a potentiometer 120 controls an automatic scan generator 126 whose output is applied to a differential amplifier 130 which also receives an input from a potentiometer 134. The motor is energized from the amplifier 130 and is mechan-  ically coupled to the wiper of the potentiometer 134 so that the motor produces an oscillatory motion corresponding with the waveform of the generator 126. The scan generator 126 comprises a capacitor 62 which is charged and discharged through constant current networks utilizing transistors 82, 58. A multivibrator comprising transistors 34, 42, determines whether the capacitor 62 is to be charged or discharged. When transistor 42 is conductive and transistor 34 is non- conductive, transistor 82 supplies current to the capacitor 62 since transistor 78 is biased to an ON condition. As the voltage across the capacitor increases, the output emitter of the pair 84, 86 increases in potential until transistor 52 conducts. Transistor 42 is then biased OFF and transistor 34 conducts, whereby transistor 58 is turned ON through diodes 44, 56, to start discharge of capacitor 62, the transistor 82 being turned OFF. The discharge of the capacitor 62 continues until the voltage at the emitter of transistor 86 drops to a level which biases transistor 22 OFF causing transistor 28 to conduct and render transistor 34 non- conductive, thereby re-establishing the original conditions. Resistors 108, 112, are adjusted respectively to vary the low and high voltage points of the output waveform which is taken from the emitter of transistor 86. A potentiometer 14 may be used to vary the potential of the output waveform with respect to earth, and resistors 90-98 provide various slopes in the rising voltage portion of the output waveform. A resistor 60 may be variable to adjust the falling portion of the waveform. Diodes 64, 66, and 100, 102, provide a constant bias voltage to transistors 58, 82, respectively, so as to provide constant current operation.

[Also in Divisions D1-D2] An insulating lining 4 comprising batting of phenolic fibres or filaments of a cured resin condensation product of a phenol and an aldehyde is secured to a metal shell 3 by anchors 5. The fibres may be made from resoles, which are thermosetting, from novolacs, which are cured by treatment with compounds such as aldehydes or hexamethylene tetramine, or from combinations thereof. The batting can be made self-supporting by treating the fibres so that they become secured to each other, e.g. by curing if uncured fibres are used, or by spraying with a thermosetting resin if cured fibres are used, or by packing the fibres to a sufficient density, e.g. 10<SP>-3</SP> to 1 gm./c.c. In an example, novolac filaments were made by heating a novolac to 135‹ C., drawing the resulting melt through an orifice and winding the filaments so produced on a spool. The uncured filaments had a slightly elliptical cross-section and were cured by immersion in a heated aqueous hydrochloric acid-formaldehyde solution.

Microporous sheet structures which have a Shore A hardness of at least 40, a tensile strength of more than 70 kg. wt./cm.<SP>2</SP> and a softening point above 100‹ C. are prepared by a process in which aqueous dispersions of polymers of olefinically unsaturated compounds are coagulated with shaping by producing a polyurethane-polyurea in the dispersion. The polyurethane-polyurea is suitably produced by reaction of (i) an isocyanate terminated prepolymer with water or a di- or polyamine, (ii) an amine terminated prepolymer with a di- or polyisocyanate or (iii) an isocyanate terminated prepolymer with an amine terminated prepolymer. The dispersion of the polymer of olefinically unsaturated compounds may be emulsified with one of the starting materials for the production of the polyurethane-polyurea and the other starting material is then added before shaping. Suitable polymers used as aqueous dispersions are rubber lances, polybutadiene lances, SBR latices, polyisoprene lances, polychloroprene latices, nitrile rubber latices or latices of thermoplastic resins such as polyvinyl chloride, styrene/acrylonitrile or polystyrene. A non-solvent in addition to water for the polymers may be added to the emulsion before shaping to produce microporous products by the coagulation technique.
