Abstract: A dispenser guides a web from a roll of sheet material over a feed roller to a position to be grasped by the user while roller mounted knife means cuts the web into individual sheets and a manually engagable handwheel, rotatable with the feed roller, provides peripherally spaced finger notches to facilitate manual forward rotation of the roller in dispensing the material. The notches are formed differently in separate circumferential portions of the handwheel such that pawl means, successively engaging the notches incident handwheel rotation, prevents reverse rotation of the feed roller throughout a first portion of each feed roller revolution and biasing means acts to cause reverse rotation throughout a second portion of the feed roller revolution to assure return of the knife means to a safe inaccessible location within the dispenser when the handwheel is released.
Abstract: A force may be applied to any point along a line which may be straight or curved in a plane or in space. For this purpose a force applicator is used which includes a pressure expandable hose section closed at its ends, a reaction member against which the hose rests, and a pressure transmitting plate moving in response to an expansion of the hose. These three elements are held in an operative position relative to one another by a modular frame section which also holds a guide member and a reset element for restoring the hose section to a starting position when no pressure is applied inside the hose. A piston rod extends through the guide member and is operatively connected to the pressure transmitting plate. The modular frame section, the guide member and preferably also the reset element form a modular unit.

Abstract: A method and apparatus for continuous cold cutting or slitting of a flat material wherein the flat material is subjected to a first step of partial-shearing or penetration in a zigzag state to a controlled depth of penetration, and subsequently to a second step of flattening, thus forcing the penetration formed in the material back to substantially the original thickness of the material, thereby to perform complete severing or slitting the material having no burrs formed during the operation. The first working action is obtained from feeding of the flat material into the controlled spacing of opposing pairs of cutter discs so that there occurs partially shearing or penetration in the flat material under an optimally predetermined interfering action by the opposing pairs of cutter discs into the material when it engages therewith.

Abstract: The rotary heat cutter comprises a heating element adapted to be rotated into engagement with a taut section of plastic web to sever the web transversely while the web is traveling in a straight path. Means are provided for constraining the heating element to move at the same speed as the plastic web when the heating element engages the web.
Abstract: A base frame mounts a first gang of saws in a common vertical datum plane and a first wood member conveyor device. A second gang of saws in a common vertical datum plane and a second wood member conveyor device are mounted on a carriage on the base frame for movement toward and away from the first gang of saws and first conveyor device. Each saw in each gang is independently vertically adjustable in its vertical datum plane and each saw is rotatable a full 180 degrees around the axis of a chord on the saw blade lying in the common datum plane of such saw. Each saw, during its angular rotation, is precisely supported on a double pantograph movement linkage which follows an arcuate track centered on said chord and vertical datum plane. A precision drive for the wood member conveyor devices and carriage obviates the necessity for a long torque shaft and enables much greater versatility of operation of the apparatus.
Abstract: A rotary slicing tool is provided for a food processor having a hub with a horizontal disc-like member carrying an elevated slicing blade.

The pneumatic capacitance is adapted to be charged in response to the initiation of a first operative cycle of the feeder and to be discharged in response to the completion of said first cycle; said discharge being adapted to initiate a second operative cycle of said feeder. Once triggered the feeder may execute a number of successive operative cycles, the particular number being dependent on the effective volume of said pneumatic capacitance.
Abstract: The present apparatus applies force along a line or to a surface through one or more linear or rather longitudinal, elastically expandable or deformable members. The expansion of the elongated member, such as an elastic, reinforced hose or membrane, is transmitted to the tool proper, for example, a strip steel knife or a clamping device, along the entire length of the tool, whereby a linear force application is achieved. Several of such members may be arranged in parallel to obtain substantially a surface area force application. The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.

Abstract: A device is disclosed for severing both a needle portion and an end nub portion of a syringe. The device includes a receptacle for the cutoff portions and a removable cover. A horizontally movable severing means may be suspended from the undersurface of the cover. Mounted on the cover is a handle which is mechanically linked to the severing means. Actuation or movement of the handle thereby causes horizontal movement of the severing means. By resting the syringe in a shoulder portion of the cover, the needle and nub portions of the syringe extend downward through an opening and are in line with the severing means. Therefore, when the severing means is moved in a horizontal direction, it will necessarily cut off the needle and nub portions.
