The rectangular relatively rigid shirt board supported folded shirt is inserted into a transparent envelope of polyethylene or the like, with the envelope according to the invention formed with a relatively larger volumetric capacity at the relatively bulkier collar supporting portion of the shirt wrapped shirt board, and a relatively smaller volumetric capacity at the shirt body supporting portion of the shirt wrapped shirt board, so that the envelope snugly engages the shirt wrapped shirt board.

Abstract: Method and apparatus for producing pressed board and the like in a tiered, multi-opening press, in which the sheet blanks are deposited individually on conveyor platens which are conveyed by conveyor means successively at predetermined intervals to a stacking device. In the stacking device, a predetermined number of platens with their superposed board blanks are successively raised above the conveyor means into retained contact with one another to form a stacked assembly of platens and board blanks. When the predetermined number of platens and board blanks have been stacked, the assembly is lowered onto the conveyor means and transported to tiered racks in an elevator device by which they are successively elevated into alignment with the tiered openings in the multi-opening press to be pressed into board units in a single pressing operation.

Abstract: A pendular suspension system for vehicles running on railroad tracks, which comprises resilient means for tilting the vehicles in response to unbalanced centrifugal force, located symmetrically on either side of a central vertical longitudinal plane of the vehicles and being independent of one another. Resilient means are arranged to bear upon a base located above the center of gravity of the vehicle bodies and are able to yield vertically and horizontally in response to the resultant imbalance of the centrifugal force to induce increased tilt of the vehicle bodies in addition to the normal cant when the vehicles travel around a curve and become operative only when the train reaches a speed above a predetermined minimum and only when the track has a predetermined degree of curvature to thereby reduce the passenger feeling of unbalanced centrifugal force.

Abstract: A static discharger includes a vertical casing connected to a pressurized pulping digester for receiving a stream of fibrous material and having a valve isolated scrap collector positioned on its lower end. A discharge neck on which a blow valve is mounted extends from the casing above the scrap collector and is covered with a grid plate having self-cleaning openings. A pipe mounted tangentially on the casing introduces flooding liquid thereto while a similar pipe may be located on the scrap collector. A sealed casing cleanout opening may be provided. No moving parts are involved since discharger agitations result from the flooding media. Heavy foreign body impurities in the stream sink to the scrap collector where they are removed without process interruption. Buoyant objects remain suspended in the liquid. Blow valve plugging is eliminated. For higher fiber consistency, a grid plate wiping agitator may be advantageously installed in the casing.

Abstract: The present invention relates to a new container that can be displaced by rotary force, consisting of a continuous sheet that assumes a form similar to a cylindrical surface, generated by a rectangle whose shorter sides have been substituted by convex semicircumferences, when it rotates around an axis that is very close and parallel to one of the long sides. An element is then placed in the direction of the axis and forms the axis of rotation. This element is held fast by the container when the latter is filled with fluid or other matter that induces multidirectional pressures of sufficient magnitude to cause the element installed, when impelled by a force, preferably along the axis but from either direction, to pull with it the enclosed sheet, thus displacing the container by rotary force over the supporting surface.

Abstract: An improved thrust bearing of the double acting type has separate tiltably mounted bearing blocks arranged in plane ring segments on each side of a bearing box. The separate bearing blocks are movably supported on hydraulic pistons which are axially movable in corresponding hydraulic cylinders. The hydraulic cylinders on each side of the bearing box are connected by hydraulic pressure transmitting channels individually to separate hydraulic pressure sources so that each bearing block ring segment will have its own pressure while the bearing blocks within each segment will have the same load.

Abstract: A stream of disintegrated fibrous cellulosic pulp material and steam under pressure is subjected to an instantaneous pressure reduction as said stream and steam pass through a throttling nozzle, in a throttling zone, wherein a liquid solution of a bleaching agent is admixed with said stream and which stream, admixed with bleaching agent, is then passed into an expansion zone ahead of the throttling nozzle resulting in a uniform dispersion of the bleaching agent into the fibers in the stream of fibrous cellulosic pulp material.

Abstract: A piston pump assembly is disclosed in which the rotation of the drive shaft of the driving motor reciprocates the piston via a single-row spherical ball bearing which is eccentrically arranged in relation to the drive shaft. The piston is turned about its linear path of movement in synchronism with its reciprocation.

Abstract: A motor driven by a pressurized fluid medium for operating an impact tool in a linear direction adapted for metal stamping and high velocity milling comprising a housing and a piston unit. The latter comprises a drive piston, a piston rod and a tool. In addition, the motor includes a kinetic energy absorbing device comprising a hydraulic fluid chamber and a retard piston which is rigidly connected to said piston unit and arranged to reciprocate in said fluid chamber. The retard piston retards the piston unit at the end of the strokes only and is freely passed by hydraulic fluid during the working stroke. Cup-shaped means are provided to restrict said by-pass flow of hydraulic fluid at the end of the strokes and thereby protect the motor from excessive stresses during no-load conditions.

Abstract: A valve system for controlling the flow of hydraulic fluid for opening and closing the main control valve for a turbine system. The valve system comprises: first valve means for passing hydraulic fluid to the servo motor to maintain the control valve open during normal operating conditions of the turbine and to interrupt the supply of hydraulic fluid in response to a predetermined normal pressure drop; second valve means for draining hydraulic fluid from the servo motor to close the control valve in response to a predetermined normal pressure drop in the turbine system; and third valve means for separately draining hydraulic fluid from the servo motor to relieve the latter of pressure rapidly in response to an abnormal pressure drop in the turbine system with consequent rapid closing of the control valve.

The other two opposing edges of the metal sheet form projections having thickened reinforcement edges.

Abstract: An improved apparatus and method for manufacturing ground wood pulp from ligno-cellulose containing wood block material by forcing the block material to be ground against the end surface of a rotatably mounted grinding disc which has projecting grinding means in the shape of elevations or ridges located on the disc end surface which define grooves directed towards the end surface circumference. The apparatus includes a pressure plate for pressing the block material along a longitudinal side against the disc end surface with the fibers directed outwardly from the center of the grinding disc and toward the periphery of circumference of the disc while the fibers are separated. In this manner the fibers are oriented in the same direction as the edges of the elevations or ridges which carry the fibers radially outward and the elevation edges engage the block fibers under a movement component which is transverse to the longitudinal direction of the fibers.

Abstract: Lignocellulose fiber containing chips, preheated with steam liberated from a previous chip defibration, are dewatered and then defibrated in an atmosphere of saturated steam and in the presence of backwater and suspended in backwater to form a pulp suspension whereafter wet sheets are formed from the pulp suspension, water is mechanically removed from the wet sheets and recycled as backwater to be supplied simultaneously, with dewatered chips, to the defibration step and to form a new pulp suspension and said wet sheets are dried.

Abstract: An improved locking mechanism for a safety belt of the type having a rotatable storage reel from which the belt may be automatically wound and a pivoting pawl for engaging the teeth of a ratchet wheel connected to the reel for locking it in position to prevent rotation includes the provision of an oval shaped bearing hole means located within the pawl for permitting sliding movement of the pawl on a pivot in addition to pivoting movement. A recess means formed on the pawl receives the arm of a lever for actuating the pawl and defines a cam-like surface on which the lever arm slides so that the lever returns to its position prior to actuation when the pawl slides on the pivot after locking engagement with the ratchet wheel. The oval shaped bearing hole may have a longitudinal axis substantially parallel to a plane tangent to the circumference of the ratchet wheel thus providing a high moment of force on the ratchet wheel along with a small bearing load on the wheel and pawl.

Abstract: The invention relates to a screw press for dewatering suspended fibrous pulp. The press comprises a tubular casing with perforated wall and a screw member rotatable within the casing. The desired degree of dewatering is controlled by a throttling member adjustable so as to generate a predetermined counter-pressure against the pulp advanced by the screw member. It rather often occurs that the pressure produced in the press becomes so high that the rotation of the screw member is stopped which means total stop of the operation of the press. The invention provides means adapted automatically to avoid such undesired stop in operation by relieving the press from internal pressure exceeding a predetermined, adjustable value.

Abstract: A heat exchanger panel formed from two superimposed plates, at least one of which is folded on itself longitudinally to create a series of outwardly extending open-looped fins, serving as multiple ducts to provide free passage and direct prime heat-exchanging fluid contact along the entire inner wall surface of the fins.

Abstract: A method and apparatus provides conditioning of an air stream by cooling in a regenerative heat exchanger having two groups of channels separated from one another by walls through which heat exchange occurs. The air stream to be conditioned flows through one group of channels while an auxiliary air stream flows through a second group of channels the walls of which comprise wettable material maintained wet by means of water which is caused to evaporate by the auxiliary air stream to result in cooling. The wettable material provides a substantially stationary liquid layer maintained in the channels of auxiliary air flow so that evaporation takes place directly from the walls separating the two groups of channels to obtain high heat exchange efficiency.

Abstract: Device for counteracting imbalance in a rotary body and automatically restoring it to a balanced condition. The device comprises a fluid-filled bore in which a throttling member moves freely, which transmits the pressure differentials developed about the axis of rotation during rotation of the body to a balancing mass movable in chambers disposed about the bore to displace the balancing mass a distance proportional to the pressure differentials and is effective upon the balancing mass to restore the body to balanced condition.
