Abstract: Apparatus for detecting a defect in a conveyor belt includes anchors holding a line substantially taut in a position extending across and in close proximity to a moving surface of the conveyor belt, and a trigger device responsive to loss of tension or increased tension in the line, caused by disturbance of the line by a protrusion in the belt surface arising from the defect, to initiate a reaction to the disturbance.

Abstract: A magnetic structure for use in a chain saw or edge trimmer ignition system or the like where the ignition system includes a flywheel having a plurality of cooling fins disposed around the peripheral portion thereof and at least one magnetic structure embedded in the periphery, a magnetically permeable core disposed adjacent the flywheel, a coil wound on the core and connected to an ignition circuit so that a voltage waveform is induced in the coil and applied to the circuit each time the magnetic structure passes the coil, the magnetic structure including (a) a magnet having first and second end faces and (b) first and second pole pieces which respectively engage the end faces, the pole pieces being asymmetrical in a plane perpendicular to the plane of the flywheel to thereby effect concentration of the flux produced by the magnet and coupled to the core by the pole pieces to thereby permit a reduction in size of the magnet without substantially lessening the energy in the voltage waveform applied to the ign

Abstract: The invention provides an alphanumeric display module of four controllable cells, each constituted by electrically selectable elements that is able to provide significantly increased vocabulary of words considered essential for merchandising, such as "SAVE" and "BUY", displayed in an acceptable unambiguous manner, while requiring less than 40 electric control lines, so that currently available 40 terminal memory storage devices can be employed in a simple and economical control circuit. The first two cells are of conventional "figure 8" configuration, each employing seven controllable elements. The third cell includes an upward right inclined element in its lower half thus, for example, removing ambiguity between "U" and "V", while the fourth cell includes an additional vertical stroke of two separate elements between and parallel to the existing vertical strokes to permit, for example, acceptable display of "T" and "Y" and "W".

The brush cylinder is carried by and journalled in a yoke (21) or corresponding element, which is mobile with respect to the carriage and constitutes or is a part of a front lever arm of a double lever (37), the rear lever arm of which is made up of or is a part of the manually operated handle (28, 44) of the carriage, said lever being hinged to the carriage (1) with a horizontal first turning axis (36) and permitting the brush cylinder to be raised or lowered with respect to the surface to be swept and the pressure of the brush against said surface to be adjusted by means of said handle by moving said double lever about said horizontal first turning axis.

Abstract: A display panel constructed from a plurality of similar panel members 10 having a cross-section shaped to provide an undercut recess 14, 16 extending throughout its length along at least one of its longitudinal edges. Each panel member has a formation 22, 26 along one longitudinal edge and a correspondingly shaped formation 22, 26, along another longitudinal edge, so that the panel member can form a tongue and groove joint with a similar panel member. The relationship between the undercut recess and the adjacent formation is such that when a joint with another panel member is effected the undercut recess remains open. Thus the panel members can be used to construct a slatted panel display system.

Abstract: A process for producing a powder of microcapsules characterized by adding an aldehyde resin precondensate to a microcapsule dispersion prepared in water or a hydrophilic medium with use of a water-soluble high molecular compound as an emulsifier, maintaining the resulting mixture in a condition for promoting polycondensation of the precondensate, and removing the dispersing medium from the reaction mixture, and a process for producing a powder of microcapsules characterized by emulsifying a hydrophobic core material containing a specific oil-soluble melamine-formaldehyde resin precondensate in water or a hydrophilic medium, subjecting the emulsion to a condition for promoting polycondensation to form capsule wall films and obtain a microcapsule dispersion, and thereafter removing the dispersing medium from the dispersion are disclosed.Further, processes for producing a non-aqueous microcapsule composition are also disclosed.

Abstract: At peat mining peat is suspended in water to a slurry or suspension which is led to a dewatering plant. From the dewatering plant (13) return water is returned and used to heat the raw peat in connection with the mining area. The return water can be spread onto the moss over an area (11) at a suitable distance from the mining pit (2), thereby at least partially displacing the moss water and providing water for making a slurry, the moss water preferably being drained to the mining pit. The return water contains also a separated fine parts fraction of the peat as well as peat ash and/or other chemicals which break down the colloidal bonds of the peat and which preferably also raise the pH-value of the water which is drained into the mining pit together with said fine parts fraction.

Abstract: An automatic transmission for a bicycle comprising a sprocket wheel of variable diameter, for receivably engaging a linked bicycle chain, drivingly connected to a bicycle wheel. The diameter of the sprocket wheel can be varied in relation to the angular speed of the bicycle wheel. Variation in the diameter of the sprocket in response to drive pressure applied by the linked bicycle chain is prevented by a locking mechanism.

Abstract: An improved pressure type connection on stepped-thread Hydril-type tubing and casing tool joints is disclosed, wherein a secondary sealing means is included between the stepped threaded areas of the Hydril-type connector. The secondary sealing means includes an annular ring of relatively rigid, internally tenacious plastic or rubber material, which serves to contain well pressure if the metal-to-metal sealing surfaces on the pin and box members of the Hydril-type connector are damaged. With such secondary sealing rings, damaged Hydril-type connectors can still be used, without having to scrap same, or having to repair the damaged area at great expense.

Abstract: A process for the separation of weak organic acids such as ethanol or methanol from dilute aqueous solutions thereof. The process comprises dissolving in the solution an amount of at least 26 grams/100 ml of solution of a base or a basic salt, such as potassium carbonate, the conjugate acid of which has a pKa value of above 6 and which has a solubility of at least 26 grams/100 ml. of solution and is substantially more soluble in water than in the organic acid, and separating from the solution a phase rich in the organic acid and an aqueous phase rich in the base or basic salt. The process is particularly applicable to the separation of ethanol from fermentation media as the high ionic strength of the dissolved base or basic salt causes flocculation of the dissolved solids component of dunder.
