Abstract: A wobble drive for imparting reciprocating motion to a sickle bar includes a wobble drive shaft rotatable about a first axis and having a cylindrical wobble section formed about an axis making an angle of about 14.5° to the first axis. A toroidal wobble shaft bearing housing is mounted on the wobble section by a set of wobble bearings having their outer races pressed into the bearing housing. An output yoke is coupled to the wobble shaft bearing housing for transmitting the oscillatory motion of the housing, caused by rotation of the drive shaft, to a swing arm fixed to an end of a shaft portion of the yoke. The coupling of the yoke to the wobble bearing housing is accomplished by a pair of headed spindle pins inserted, from the inside out, through pin bores provided at diametrically opposite locations in the wobble shaft bearing housing, and into respective yoke bearings mounted in the ends of a pair of yoke limbs that are joined to the yoke shaft portion. The heads of the spindle pins are respectively received in counterbored sections at the radially inner ends of the pin bores and these counterbores are blocked by outer races of the set of wobble bearings carried by the wobble bearing housing. The pins are each stepped to form first and second sections of different diameters with the radially inner section being larger than the radially outer section and sized for an interference fit with the bearing housing and with the radially outer sections being longer than the pin bores so as to permit the pins to be freely manually inserted through the pin bores and partially into the pin bearings carried by the yoke limbs, whereby the bearing housing and output yoke may be properly aligned one with the other prior to the pins being mechanically pressed into the pin bores.

Abstract: An apparatus for loading an article into a bag. The  apparatus  comprises  a  loading  station  which  is positioned adjacent a conveyor carrying the articles to be filled in the bags.  The loading station comprises a bag delivery plate, a bag bottom opening plate, a bag opening plate and a pusher arm.   The bags are folded flat and stored in a hopper.  The bag delivery plate retrieves a bag from the hopper and holds the bag in the loading station. The bag bottom opening plate engages the bottom panel of the bag, while the bag opening plate engages a facing panel of the bag.  The bag is opened by actuating the bottom and opening plates.   When the bag is open,  the pusher arm pushes the article from the conveyor into the opened bag. The filled bag is then moved to another conveyor for packing.

Abstract: The disclosed cylinder for heat-treating a web is rotatable about a horizontal axis and is heated by a complement of internal stationary infrared burners that extend all along the length of the cylinder, but whose arcuate extent is limited for establishing a specified cylinder heat output when the burner(s) is (are) supplied with air-fuel mixture at their maximum rate. Reduction of the air-fuel supply rate over a wide range allows the cylinder heat output to be reduced as the web processing speed is reduced. When the burner is divided into segments, the temperature profile along the cylinder; i.e., across the width of the web, can be regulated to adjust the moisture profile of the web. An exhaust manifold within and along the cylinder is configured so as to avoid any local accumulation of high-temperature exhaust. A paper or paperboard making machine that is in existence, having steam-heated cylinders, may be retrofitted with the novel cylinders, as substitutes for selected steam-heated cylinders at those locations where there is greatest gain; alternatively, all of the steam-heated dryer cylinders of a paper or paperboard machine may advantageously be replaced by the novel cylinders, heated by stationary internal complements of IR burners whose arcuate extent is varied, cylinder-to-cylinder, in accordance with their respective desired operating temperatures. For greater effect, adding a stationary external IR burner opposite to a novel internally heated cylinder heat the web simultaneously from opposite sides and within its thickness, by penetrating infrared radiation.

Abstract: An apparatus for decurling a sliced food material, for use with an automated slicer wherein the food material is carried in a reciprocating arcuate or linear movement. The sliced material is passed through a constricted space between separate stationary and moving surfaces. The moving surface moves relative to the stationary surface at a speed that is at least as fast as the speed at which the food is carried towards the knife. The moving surface is incorporated within a guide plate which has a profile that approximates the arcuate or linear path of the food in its travel into and out of contact with the knife. The moving surface may consist of an array of rotatably driven elastic bands or belts that travel within a series of grooves within the guide plate, and which are driven by a driving roller. The belts serve to transfer the sliced food to another work station and prevent the food supply from being pinched against the guide plate.

Abstract: A conveyor system having an infeed conveyor section, an outfeed conveyor section, and a working conveyor section positioned in between and in line with the infeed and outfeed conveyor sections. The working conveyor section includes a base and a frame which is movably mounted relative to the base between a lower position and a raised position. In order to move the frame between its lower and raised position, a driver is rotatably mounted about a substantially horizontal axis to the base while an elongated drive link has one end pivotally connected to the frame and its other end pivotally connected to the driver at a position radially spaced from its axis. A drive mechanism selectively pivots the driver between first and second rotational positions which are spaced substantially 180 degrees from each other. In doing so, the coaction between the driver and the drive link moves the frame between its raised and lowered position.

Abstract: Disclosed is a modulation method for wireless signal transmission. Each message that is transmitted is made up of a sequence of signals, each selected from a constellation of L such signals, L a positive integer. Each transmitted signal is distributed spatially across a transmitting antenna array, and is also distributed in time. Thus, each signal may be represented as a TxM matrix, in which each of the M columns represents a distinct antenna of the array, and each of the T rows represents a distinct time interval. Each entry in this matrix represents a complex baseband voltage amplitude. Each of these signal matrices is proportional to a matrix having orthonormal columns.
