Title: Short-circuit protective device for direct current power transmission lines
Inventor: MARANCHAK VASILY MAKAROVICH
IPC: H02H3/08
Filed: 1965-12-21
Abstract: 1,120,460. Protective systems; converting, MOSKOVSKY ENERGETICHESKY INSTITUT. 21 Dec., 1965, No. 54190/65. Headings H2F and H2K. [Also in Division H3] A protective arrangement for a D.C. transmission line comprises a voltage divider 10 connected to the protected line, a differentiating unit 1 connected to the voltage divider and an actuating unit 2 connected to the unit 1 which comprises two transformers 3, 4 interconnected by a capacitor 7. When the line voltage falls due to a short circuit condition, the differential unit produces a single voltage pulse which is approximately proportional to the third derivative of the line voltage and enables the arrangement to distinguish between a short circuit on the line and a short circuit in an inverter. Diodes 5, 6 and 9 in the differentiating unit increase the sensitivity of the arrangement. The voltage pulse is applied to the base of a normally non-conducting transistor 11 in a monostable circuit. This circuit includes a normally conducting transistor 12 having its collector connected to the base of the transistor 11 through a resistor 16 and a choke 17 to prevent the input voltage being shorted out by the transistor 12. A relay 24 is connected to the collector circuit of the transistor 11 and a time delay is provided by a resistor 22 and capacitor 21. In a modified arrangement, Fig. 2 (not shown), the second transformer has a rectangular hysteresis loop core and a magnetizing winding.

Member 1 has a handle 2 and carries two axles 5 each rotatably carrying brushes 3 and sponges 4 of diameters decreasing towards the outer ends of the axles. The sponges and brushes on each axle are locked so as to rotate together Fig. 8 (not shown). The tray has a floor 19 with a series of longitudinal channels leading into the fluid reservoir 16. The reservoir is otherwise sealed and the liquid in the tray is thus automatically held at the level of the tray floor surface. Alternatively the level may be held at a higher level by providing an opening 26, Fig. 2 (not shown), higher than the floor level. The tray also has transverse grooves.

In a film resistor comprising conductive particles in a non-conductive material, the non- conductive material is a synthetic polymer capable of being cross-linked by irradiation, so that the film may be hardened quickly without the action of heat. The radiation may be X-rays, y-rays, electrons, neutrons, protons or α- particles, with a dose in the range 1 to 30 megarad. The polymer used may be acryl monomer-polymer mixtures, acryl polyester resins, acrylically modified epoxy resins or unsaturated polyester resins. The conductive particles, added in a volume concentration of 15-85%, may be finely divided metals, e.g. Fe, Cu, Cr, Al, Ag, Au, or their alloys, with particle sizes 10-100 Á; or they may be finely-divided graphite, or acetylene carbon black with a specific surface 80-150 m.<SP>2</SP>/g. For high resistance resistors semi-conductive particles (metal oxides, e.g. SnO 2  or Sb 2 O 3 , or sulphides, e.g. CdS and PbS) may be added together with the conductive particles, in such proportions that the total filler volume concentration is 25-50%. For resistors to be used as slide rheostats &c., substances having a dihexagonal-bipyramidal crystal structure may be added in volume concentration 1-10% to improve sliding properties and reduce wear. Of such substances, graphite will serve simultaneously as conductive material and molybdenum disulphide as semiconductive material. Details are given in the Specification of the production of the conductive particles, the mixing of the particles and the other material, the polymerization process, and the acceleration, deflection &c. of the electron beam.

Abstract: 1410797 Growing algae and purifying water BIO-KINETICS Inc 6 Dec 1972 [6 Dec 1971] 56382/72 Heading C1C [Also in Division C6] A method of growing unicellular and/or filament-form proteinaceous algae and simultaneously purifying biodegradable waste material comprises aerating and agitating an aqueous admixture of algae and waste material, the waste material providing nitrogen and phosphorus nutrients, circulating the admixture, exposing the admixture during circulation to light capable of inducing photosynthesis and then subjecting the admixture to a significantly longer period of darkness, these latter steps being repeated for several cycles to effect growth of an algae product and consumption of the waste in the presence of carbon dioxide (formed during aeration; additional CO 2  may be added). Sewage wastes may be used as nutrients. Apparatus for use in the process comprises a tank with a base, a first and second side wall, and two end walls, and being open at the top for exposure to light, the first side wall being in the form of a section of a parabolic curve, injector means disposed in the base opposite the first side wall, horizontal baffles in the upper portion of the tank, and means for injecting fluid toward the first side wall to impel fluid to move up this wall and to flow over the baffles providing the exposure to light, and to flow below providing the subjection to darkness for a much longer period. Clean water and an algae product high in protein may thus be produced in a batch or continuous system, in the presence of added air and/or carbon dioxide as required to help the growth of aerobic bacteria or the algae respectively.

Title: Change speed gearing
IPC: B62M11/14
Filed: 1972-12-07
Abstract: 1383099 Change-speed gear FICHTEL & SACHS AG 7 Dec 1972 [16 Dec 1971] 56604/72 Heading F2D A pedal drive for a toy vehicle, which provides a forward one-way one-to-one drive by forward pedalling; a backward one-way one-to-one drive by back pedalling; and a one-way forward overdrive introduced by an additional control or by momentary backpedalling, comprises a planet gear having an output ring gear 7 pinned at 15 to a central output shaft, not shown; a sun 11 on a hollow shaft 1 which can be held in one direction in Figs. 1-4, or is permanently fixed, Figs. 5 and 6, not shown; and a planet-carrier 8, which, like the ring 7 can be driven by selectively controlled pawls 3a, 3b, 4, as described below, on a freely mounted input sleeve 2 on which is fast a sprocket 6 chaindriven by the pedal cranks, not shown. Oppositely acting pawls 3a, 3b, Fig. 3, socketed in the input sleeve 2, are outwardly biased by a surrounding spring 5 towards engagement with internal ratchet teeth in the ring gear 7, whilst a single set of forwardly directed pawls 4 are similarly biased towards engagement with the planet carrier 8. Release of the pawls for outward engagement with their respective ratchets occurs selectively when a recess 25 in a freely mounted plastics control ring 21 overlies the respective pawls, the control ring being turned selectively as follows, the ring being frictionally held by a surrounding ring 22 having projections 23 straddling a lug 24 on a stationary casing 20. On forward pedalling (input shaft 2 counterclockwise in Fig. 3) a lug 29 projecting axially from a part 19, attached to the input sprocket 6, strikes an internal abutment 27 in the control ring 21, thereby dragging the ring forwards until its recess 25 overlies and releases the pawls 3a and 4, the former then driving the output ring 7 forwards at one-to-one one-way, the latter idling the carrier 8 forwards. For overdrive, a spring-loaded cable-controlled wedge-ended plunger 31, Fig. 4, is manually allowed to enter into one-way engagement with teeth 16 on the sun shaft 1, thus stationing the latter, and the pawls 4 drive the carrier 8 to overdrive the output ring 7, the ring pawls 3a being then overrun. On back pedalling (shaft 2 clockwise, Fig. 3), a second lug 28 on the input-connected part 19 strikes the other end 26 of the ring abutment and turns the control ring 21 backwards until its pawl-release recess 25 overlies and releases the single pawl 3b, which then engages the output ring 7 for a backward one-way drive. In Figs. 5 and 6, not shown, the sun shaft 1 is permanently fixed and the pawl release recess 25 of the control ring 21 releases only one pawl at a time, so that initially, on forward drive, the pawl 3a is released alone; momentary back pedalling releases the second pawl 4 alone to drive the carrier 8 for overdrive; and continuous back pedalling releases the pawls 3b alone for one-to-one backward one-way drive.
