Abstract: A currency note dispenser especially adapted for under-the counter use in which a conveyor carries notes removed from the bottom of a supply stack to a delivery tray at an access location above the supply. In response to a malfunction of the dispenser, an energizable element moves the tray to an inoperative position at which notes previously delivered thereto fall to an escrow area in the dispenser cabinet and hold the tray in that position until all notes received by the conveyor have passed to the escrow area. Before moving the tray, the energizable element releases a mechanical lock which prevents movement of the tray to its inoperative position in the absence of energization of the energizable element.

Abstract: A sheet feeder in which a cam member shiftable transversely of the sheet feed path provides concomitant adjustment relative to the feed rollers of stripper shoes carried by resilient arms integral with stripper supports mounted for movement as a unit relative to the feed rollers and in which elements on the supports adjust the positions of the resilient arms for individual adjsutment of the shoes. A rib on a curved guide adjacent to the feed rollers prevents snapping of sheets against the feed rollers as they are picked up by an accelerating nip formed adjacent to the end of the guide by a pair of acceleration rollers, one of which is formed with a groove for accommodating the nip.

Abstract: A plug connector for high-voltage coaxial cables. The cable comprises an inner conductor, an inner insulation, a metallic screen netting and an insulation, outer sheath. The plug connector comprises a plug-in contact element connected to the inner conductor, a metal sleeve connected to the screen netting and an insulating housing connecting the contact element to the metal sleeve. A sealing sleeve made of elastic, electrically insulating material is pushed onto the inner insulation of the cable. The contat element penetrates into the inner conductor such that the inner insulation arranges itself sealingly againsts the inner surface of the sealing sleeve. Owing to the connection of the insulating housing to the metal sleeve, the sealing sleeve undergoes such deformation that it arranges itself sealingly with its outer surface against the inner surface of the insulating housing.

Abstract: A compact disc magazine for a jukebox having an automatic mechanism for engaging a compact disc at generally diametrically opposite points and removing the disc from a location adjacent to the top of the magazine through the upper front portion thereof in which a hub mounted for movement around a generally horizontal axis has circumferentially spaced disc-receiving grooves, each of which at the removal location is limited to a segment of a disc below and to the rear of a line passing through said points and a belt extending around the lower part of the magazine for retaining discs in said grooves.

Abstract: A title display system for an automatic phonograph in which two sets of large panels, each side of which is adapted to carry three CD jackets, are arranged side by side in a recess in the front of the machine cabinet for concomitant pivotal movement of the panels inwardly or outwardly. A panel moving control system may be set in a first mode in which the panels are moved periodically to attract attention or in a second mode in which the panels are returned to positions at which predetermined pages are in view in the quiescent condition of the phonograph.

Abstract: A sheet detector comprises a pair of rollers disposed on opposite sides of a feed path, each roller having a conductive outer portion extending therearound. The conductive portions, which are supported on the roller shafts by electrically insulating, relatively yieldable cores, contact each other to establish an electrical connection in the absence of a sheet therebetween and are separated from each other during the passage of a sheet therebetween to break the connection and thereby indicate the presence of the sheet. Conductive brushes resiliently biased into circumferential grooves formed on the conductive portions couple the portions to an external circuit including a sheet counter and a length counter.

Abstract: A circular knitting machine has a needle cylinder, a supporting disk attached to the needle cylinder coaxially therewith, a bearing body for the supporting disk surrounding the supporting disk, four bearing tracks arranged opposite one another in pairs on the supporting disk and on the bearing body, and bearing balls supported on the bearing tracks. Two elastic supporting flanges, each having one bearing track of two axially adjacent bearing tracks formed thereon, are provided to compensate radial expansions.

Abstract: In order to overcome difficulties which arise when making conventional color charts and color spaces, a torus-shaped spacial structure is used as base body for the arrangement of color tones.The gray tones are located at the outermost jacket area thereof and the clearest colors are located at the inner jacket area thereof. In the inside of the body, the colors extend through all color tone steps from the clearest up to the gray tones. By means of an iterative method for the arranging of color tones in the torus, it is possible not only to discriminate the color tones for the human eye equidistantly, but also to represent the brown colors reliably.

Abstract: A sound-attenuating impact-absorbing earcup comprises a shell having a plurality of generally circular recesses adjacent to the periphery of the cup which function as stiffening contours. The stiffening contours increase the effective stiffness of the earcup shell, improving its sound attenuating capability, and also concentrate applied stress onto those portions of the stiffening contours nearest the point of applied stress. Sufficient applied force causes the shell to fracture in the areas of the stress concentrators, thereby to absorb impact energy in a controlled manner without transmitting it to the head of the wearer. To further enhance its sound-attenuating and impact-absorbing capabilities, the earcup is formed of a low-tensile-strength, high-elongation, high-loss-factor material such as polyvinyl chloride or similar polymer.

Abstract: A resilient annular earseal for sealing the region between an earcup shell and a wearer's head is formed with an aperture for receiving the wearer's ear and has an outer peripheral portion projecting a predetermined first distance toward the wearer's head and an inner peripheral portion projecting a predetermined second distance toward the wearer's head that is appreciably greater than the first distance. Since the inner peripheral portion contacts the wearer's head along a strip that is closer to the ear, and hence more predictable in its three-dimensional contour, it forms an effective seal around the entire periphery of the ear.

Abstract: Lathe comprising a main work spindle drivable by numerical control and a turret with several indexing stations, the turret having at least one drivable tool spindle, being mounted on a turret slide for rotation about a turret axis and being rotatable by numerical control about this axis by means of a turret driving device, and also comprising a switchable device for securing the turret against rotation. For positive locking of the turret and for play-free mounting of the unlocked turret, spur gears displaceable relative to one another in the direction of the turret axis are connected to the turret and to the turret slide in a rotationally fixed manner, and a bearing is provided for the turret which in the unlocked state of the latter is free from play.

Abstract: Sheet-feeding apparatus in which documents having distinguishable sides are momentarily halted by transversely spaced rollers to examine the sheets for proper orientation. A high-speed gating roller directs properly oriented sheets along the normal feed path. Upon detecting an improperly oriented sheet, the gating roller is driven in a reverse direction to drive the sheet into an inversion pocket where it is inverted before being returned to the normal path. The feed members along the inversion path are driven at a greater speed than sheets along the normal path to return the inverted sheet to it proper position in the document stream.

Abstract: Gelatine granules obtained by plasticizing conventional gelatine consist of solid gelatine particles with a water content of from 1 to 12% by weight, with a particle size of from 0.1 to 10 mm, with an entrapped air content of less than 1% by volume and with a melt flow index greater than 1 g/10 min at 110 degrees C. The granules are thermoplastic and solid or hollow molded articles can be made from them like from conventional plastics by extrusion, injection molding, blow molding and the like.

Abstract: A medical filter and catheter for positioning and using the filter, which filter is particularly intended to be implanted in a blood vessel such as the inferior vena cava through the endovenous route via a catheter. The filter has a filtering section which opens out inthe vessel when it is in position in the patient and which has no hooks for engaging the vessel wall. The filter has a holding section which holds the filter section in position in the vessel and which facilitates transition from a temporary use of the filter to definitive use.

Abstract: A fingerboard for plucked and stringed instruments comprises transversely extending frets for altering the pitch of strings which are tightened over the length of the fingerboard. The frets are divided up in the region in which the individual strings are tightened across them into fret elements which are adjustable in the longitudinal direction of the strings on the fingerboard. Structural sections in which the fret elements are individually displaceable over a large area are inserted in the fingerboard so as to extend continuously over substantially the entire length of the fingerboard and parallel to the strings. The fret elements are, furthermore, held by frictional connection in the structural sections in such a way that they are infinitely displaceable only by intentional, external force acting in the longitudinal direction of the structural sections.

Abstract: An article of paper currency to be validated is scanned magnetically along the front to obtain a set of magnetic sample values and optically along the back to obtain a set of optical sample data values. Position-shifted versions of the magnetic data values are compared with stored sets of magnetic reference values for various denominations to obtain error figures for each denomination and degree of position shifting tested. A first indication of the denomination of the currency is generated on the basis of the least of the error figures so obtained. Position-shifted and amplitude-shifted versions of the optical data values are similarly compared with stored sets of optical reference values for various denominations to obtain error figures for each denomination and combination of position and amplitude shifting tested. A second indication of the denomination of the currency is generated on the basis of the least of the error figures obtained by this latter method and compared with the first indication.

Abstract: Apparatus for feeding sheets from a pluraltiy of supplied to an output location in which a toggle linkage normally releasably positions the conveyor in an operative position from which is may be moved around an axis adjacent to one of its longitudinal edges to permit access to the feed path.

Abstract: The mass flow of the individual goods fed from a respective storage tank by a conveying apparatus is measured by a flowmeter. The mass flow is controlled via a controller. As long as the actual value of the flow masses of each separate component does not correspond to their respective rated value, all mass flows are returned via a switch-over valve and a return line back to the respective storage tank. When all actual values correspond to their rated values, the switch-over valves will switch such that the individual components are guided through the feed line to the mixing apparatus. The mixture produced in this mixing apparatus is once more analyzed by further detecting devices. If the analyzed actual values again do not correspond to the rated analyzed values, an immediate switching of the switch-over valves to the return bypass operation is again initiated.

Abstract: Safety spectacles comprising a front and pivotally attached temples adapted to extend rearwardly from the front. Each temple has a portion recessed inwardly relative to an adjacent portion of the front to form a passage to the region behind the front for ventilation. The recessed temple portions extend forwardly of the rear edges of the front so as to overlap the adjacent portions of the front and thereby increase the degree of protection to the wearer.
