Abstract: A safety brake for braking a moving member includes at least one active member co-operating by friction with a passive member. The active member is kept at a distance from the passive member by an incompressible fluid which opposes the effect of a drive element (7) that is coupled to the active member and tends to urge the active member against the passive member. The incompressible fluid is enclosed in a circuit (6) which possesses a frangible portion (8) such that when the frangible portion is broken in order to activate the safety brake, it constitutes an exhaust opening to allow the incompressible fluid to escape from the circuit (6).

Abstract: The invention relates to a method for testing and further processing eggs. According to the invention the eggs upon being supplied are first tested automatically for such major damage as open breaks and/or such dirt as blood stains. Further, each egg is scanned with a beam of light directed at the egg shell and the size of the aperture in the shell or any dirt is measured by a multiple transducer, viz. by counting the number of bright and dark pixels, respectively, and thus establishing the size of the damage or dirt, whereafter through comparison with set values it is automatically determined in what category of damage or contamination the egg in question is to be classified. The invention also relates to apparatus for carrying out this method.

Abstract: An in-line inserter device comprises envelope and insert feeding assemblies, an envelope inserting station assembly, a sealing and stacking assembly, and various diverter stations. The envelope feeding assembly withdraws envelopes from a hopper-held envelope stack and conveys them to the inserting station. Each modular insert feeding assembly comprises a hopper-held insert stack disposed above, along, and in line with an insert conveyor. The conveyor, along its track, carries inserts dispensed from the hopper-held insert stacks to the inserting station. Diverter stations are disposed ahead of the envelope inserting station for diversion of envelopes and inserts and ahead of the inserted envelope stacking assembly to divert inserted envelopes, for normal operational purposes and for rectification of sensed faults by rejection and extraction of processed faulty items.

Abstract: A resinous plastic reflector unit (1) is mounted on a receiving member (8) by at least a first and a second joining member (9, 10) to be adjustable at least about one axis. The second joining member is clamp-like and is self guidingly shoved onto a wall member (16) on a rear side of a reflector bowl (2, 3). Wall strength of the wall member is not substantially greater than wall strength of a thin wall forming the reflection bowl. The wide side surfaces of first and second such wall members run perpendicular to one another. A joint between the first and second joining members lies, when viewed in an installation direction of the reflector bowl, aligned behind a thin wall portion of the reflector unit.

The object may be a watch case or a bracelet link.

Abstract: A sheet separator device for side-by-side parallel sheet articles being handled and conveyed in sheet handling machines comprises first and second endless belt arrangements for conveying sheet articles in nips between belts, wherein first and second belt arrangements are divergently disposed in relationship to one another so that sheet articles entering respectively thereinto in a common plane in side-by-side parallel relationship are conveyed thereby along respective divergent paths. Sheet articles exiting from divergent first and second endless belt arrangements, respectively, are farther conveyed in a common plane along side-by-side parallel paths which are separated by a larger distance than the original distance between sheet articles entering the first and second endless belt arrangements.

Abstract: The method of manufacture of this watch case consists in employing a material including at least 95% copper in its composition, the remainder being made up of elements adapted to increase the mechanical strength of the copper while avoiding the toxic elements beryllium and cadmium. Thanks to this material the watch case may be stamped out in a single operation, hardened, then covered with a protective layer deposited galvanically or by a PVD process.

Abstract: In a forage harvester, a shear bar is adjusted relative to the knives of a rotating cutterhead by selectively energizing first and second motors to move one or the other end of the shear bar toward the cutterhead. A vibration sensor senses vibration of the shear bar and controls a circuit to deenergize an energized motor when vibration is induced in the shear bar. The vibration may be caused by impact of the cutterhead knives on the shear bar (a true hit) or by random noise (detected as a false hit). To discriminate between false hits and true hits, an energized motor is stopped when a first hit (true or false) is detected. A timer is set to time an interval at least as great as the time it takes the cutterhead to make one revolution, and during this interval the vibration sensor is repeatedly sampled to determine if a second hit has occurred. If a second hit is detected during the interval the first hit is assumed to be a true hit.

Abstract: A cordless telephone network comprises a base unit (12) that is interconnected into a normal telephone network (19) and a plurality of hand-held cordless telephones (20). Each of the hand-held cordless telephones has a distinctive identification code and the base unit temporarily stores the identification code of the hand-held unit with which it is communicating during a call and will not communicate with other hand-held units having different identification codes during that call. Each of the hand-held units has the ability to scan a plurality of cordless telephone channels for either receiving a call on a channel on which its identification code is transmitted or placing a call on a channel on which a base unit transmits a "free-channel" signal. The hand-held units each have a voice activation/deactivation circuit which allows the hand-held unit to send and receive audio signals only when it has been given permission to do so by a base unit.

Abstract: The invention concerns a method of and a plant for purifying water in an open, solid filter bed (17) in which, after the addition of chemicals, the water to be purified is passed through a filter bed, said filter bed being regenerated by counter-flow flushing, wherein the water to be purified in the filter bed is caused by force to flow through the bed at a constant rate by means of a partial vacuum created by a pump means (20) arranged downstream the bed (17), the flow being kept constant with the aid of a control valve (23) arranged on the pressure side of the pump (20).

A holder (A) containing the mouldings is provided with gas inlets (3). A gas flow through the gas inlet (3) brings the mouldings in a spiral rotating movement in a sphere (C) placed on holder (A). Coating material is sprayed in the apparatus by a tube (D), oscillated by the gas flow, on the whirling mouldings.

Abstract: A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions. An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector, tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber.
