Abstract: Measuring the limpness of a note is necessary to separate a worn note out of circulation. Several methods are disclosed which can be used either alone or in combination to test for limpness. One method measures the note's ability to reflect light or transmit the light. Another method measures the response of the note to an acoustic wave. Another method measures the note's deflection to a pressure or force. Yet another method measures the dielectric value of the note when placed between the plates of a capacitor. A final method involves measuring the thermal conductivity of the note. In each case, a limp note will produce distinguishable results from a stiff note.

Abstract: The invention relates to a separating apparatus for separating a mixture of materials of different flowability for preparing foodstuffs. The apparatus includes a hollow drum having a perforated circumferential surface around a portion of which is wrapped an endless presser belt forming a compression zone for the material to be processed. The belt is pressed against the drum by a presser roller having a hub body around which a tubular cylindrical body forms the roller surface. The cylindrical body is supported in its middle portion by spherical supporting element mounted on the hub body. Thus when the belt is subjected to non-uniform stresses due to the uneven consistency of fed material which in turn causes the deformation and unparallel rotation of the drum and the presser roller, the cylindrical body automatically adjusts its position on said spherical supporting element to restore parallel motion.

Abstract: A sectioning method is described for accurately and objectively classifying individual wheat kernels as hard or soft wheat. A kernel is cut to obtain a section having a thickness in the range of about 1.3 to 4.8 microns; if the section remains intact, the kernel is classified as hard, and if the section does not remain intact, the kernel is classified as soft. The method finds particular use for detection of lots of wheat where hard and soft varieties have been intermixed and for classifying breeding selections.

Abstract: A separating apparatus employs a foraminous drum with a resilient belt forming a nip therebetween. A take-up roller upstream of the nip is rotatably supported about a center of rotation that is parallel to, but offset from a central axis of the take-up roller. As the wobbling roller rotates, it constantly changes the point on the circumference of the foraminous drum at which contact is made with the resilient belt. This overcomes a tendency for entering items to bridge the nip.

Abstract: An impact separator has a V-shaped downwardly angled trough vibratorily mounted at its lower end and fixedly resiliently secured at its upper end which is fed at the upper portion with scallop and residual shell and a small amount of water while being vibratorily driven. The meat of the scallop descends downwardly and absorbs the impact of the vibrations while the shell portion is impacted by the walls of the V and eventually tumbles out over the top and descends to a trash tray positioned beneath the V-shaped trough. The scallop flesh travels the full length of the V-shaped trough to an exit hole for further processing including removal of the viscera. The trough is designed at its lower portion to permit a vibratory drive of between 0.100 inches and 0.300 inches. In one embodiment of the separator the vibrations are imparted orbitally.

Abstract: A device for sorting packagings such as cans having overall dimensions within a pre-determined range as regards length and diameter, comprising a first sorting stage, including a pivoted supporting member for carrying the packagings and a frame with an opening through which the supporting member is movable to the second stage. The second stage includes pressing members cooperating with the supporting member to effect axial compression of the packagings carried by the supporting member. The opening of the frame is of a size which limits the dimension in at least one direction of the packagings passing through the opening. The second stage is provided with a second opening through which compressed packagings pass whereby the second opening maximizes the axial length of the compressed packagings which pass through the second opening and are thereby sorted out.

Abstract: Apparatus for sorting packagings such as cans of a certain type of material from packagings of other types of materials comprising a support member transporting the packagings one by one to a compression station at which are disposed first and second pressing members arranged to move relative to each other to compress the packagings transported by the supporting member. The relative movement of the pressing members and transfer of the packagings when relative movement of the pressing chambers has ceased is controlled by a regulating mechanism such that when compressive forces of a magnitude within a predetermined range required for packagings of the type of material in question allow the pressing members to move towards each other to complete the pressing operations whereby the packagings are compressed to a size before transfer to a collecting device. In the case of compressive forces of a magnitude outside the predetermined range, the packagings are prevented from being transferred to the collecting device.

Abstract: Method and apparatus for detecting and intercepting an irregular product in a product flow are disclosed. The product flow is conveyed along a path from a first, product feed station past other product handling stations. Product flow is singulated and aligned at a guide station. The product then is delivered along a product flow axis and in a single file manner to an inspection station where the product, which may be processed, pitted fruit, is graded for firmness and where extraneous matter, such as fruit pits or portions of pits, is detected. Detection involves probing or otherwise impaling each individual product in the flow with a plurality of spaced, pin-like projections. An irregular product resists such probing and produces a pressure differential between the projections and the conveyor belt by which the irregular product is detected. After inspection, detected irregular products are discharged from the product flow.

Abstract: A batch of raisins in which moldy raisins are mixed with sound ones is immersed in a hot water bath, causing the moldy raisins to assume a mushy and sticky texture while leaving the texture of the sound raisins substantially unaffected. The batch of raisins is then dropped onto a laterally inclined conveyor belt. The conveyor belt moves the raisins over a framework which is rapidly moved up and down to slap the underside of the belt, causing the raisins to bounce up and down on the continuously moving conveyor. The sound raisins, which have retained their firm texture, are bounced substantially higher than the moldy raisins, and thus, bounce down off the side of the conveyor as they move along the length of the conveyor. Because of their mushy texture, the moldy raisins do not bounce as high as the sound ones and therefore do not as readily bounce downward off the conveyor. Instead, they are carried along and off the end of the conveyor.

Abstract: Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilence are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available.
