Abstract: A method for transferring an image from a color photograph onto an object having multiple curved surfaces utilizes a backing sheet to protect the object from the heat required for thermal transfer. The object is disposed in a press assembly near the backing sheet so that the image attached to the backing sheet may be aligned with the target surface on the object. Then, the backing sheet is moved toward the target surface so that the image contacts the target surface at a desired position. The backing sheet is further pressed against the object to deform the target surface until it is substantially flat. Heat applied to the backing sheet and the image then causes the pigment contained in the image to be transferred onto the target surface to create a mirror image without damaging the object. When the backing plate is removed, the object will substantially regain its original curvature.

Abstract: A device for measuring the complex impedance, such as the electrical conductance and/or the capacitance, of milk, for example in connection with mastitis detection, comprises a sample chamber which is provided with sensors and in which a milk sample can be received.

Abstract: The present invention discloses a data switch for a Bi-Tronics printer that keeps the Bi-Tronics printer in the use of data switch by adding a controller circuit which provides simulating responding signals to a disconnected computer. When the data switch is turned to different position, that is, the Bi-Tronics printer is in fact disconnected with the computer, a pseudo signal will be provided by the controller circuit to deceive the computer that the printer is still connected. Therefore, the driver of the Bi-Tronics printer in computer could not detect the abnormal condition of the Bi-Tronics printer, so that, the error massage will not appear on the screen and the data switch could still function properly between the computer and the Bi-Tronics printer without interrupting the user.

A drive train is interposed between and engages the second gear and the cassette drive sprocket. The stepper motor is positioned between the bellows drive sprocket and the cassette drive sprocket whereby the footprint of the labeler is minimized.

Abstract: A wrist rest for incorporation with a computer keyboard enables a user's wrist to have adequate support when typing and is able to be adapted to be incorporated with a different keyboard by adjusting knobs rotatably provided on two opposed sides of the wrist rest.

Abstract: The printing apparatus has a holding cylinder in which communication holes for communicating an external portion and an internal portion are made and a transfer pad which covers the outer surface of the holding cylinder at ordinary times in a detachable manner, expands upon pressure being applied via the above communication holes when the interior of the holding cylinder is pressurized, and contracts and returns to its original state when the pressure is released. Ink is adhered to the outer surface of the expandable/contractable transfer pad. The transfer pad is inserted in the contracted state into a cylindrical hole of an object to be printed. Pressure is applied from the inside of the transfer pad to cause it to expand and cause the outer surface of the transfer pad to press against the inner surface of the cylindrical hole and thereby transfer the ink adhered to the outer surface of the pad to the inner surface of the cylindrical hole.

Abstract: A printer apparatus (10) includes a removable print ribbon cartridge (18). The print cartridge includes a ribbon (20) which is movable by a transmission mechanism (49). A ribbon drive member (65) in said transmission mechanism includes frangible tabs (101). The frangible tabs break responsive to encountering a resistance to movement of said ribbon. The frangible tabs limit the force that may be encountered by a motor (168) used to advance the ribbon thereby preventing damage to the motor and associated drive components and circuitry in the event of a malfunction.

Abstract: A device for cleaning silicone particles and other residues from directly imaged printing forms of a printing form cylinder in a printing press includes a cleaning element extending parallel to the axis of the printing form cylinder and movable substantially radially against the printing form cylinder, the cleaning element having a cleaning surface with which it is engageable with the printing form, the cleaning surface being formed with a fleece of fine microfibers of plastic material.

Abstract: To prevent effective print speed from being lowered, a counter is provided for each of a plurality of print hammers. A number of times a print hammer is driven during one print phase having a predetermined period of time is counted by the counter. The counted value is compared with a reference value, and when the counted value has reached the reference value during the print phase, driving of the print hammer is halted until the end of the print phase. A reference value is changed based on the number of times the print hammer is driven during a previous print phase immediately before the present print phase. The reference value represents an allowable number the print hammer can be driven during each of successive print phases.

The base portion also has a litter holding wing portion operatively associated therewith and extending upwardly and outwardly therefrom. The pivotal sifting device is initially disposed beneath a layer of loose litter material. Thereafter, the sifting device is pivotally movable up through the litter material to collect clumped absorbent litter and fecal matter wastes thereupon while permitting loose litter material to pass therethrough. The sifting device is pivoted still further to deliver the wastes to a disposal site.

Abstract: A powder-dusting apparatus (4) which inside a printing machine dusts the pre-dried printed products coming from the printing unit with a powder, for example of corn-starch, comprises in a manner known per se a plurality of nozzles (6), which are charged with a mixture of powder and carrying air from a mixing device (8). The nozzles (6) are arranged in the vicinity of the plane of transport defined by the transport system (1) of the printing machine and are able to assume two different spacings with respect to that plane: ordinarily the nozzles (6) are located comparatively close to this plane of transport; during these times the mixture of powder and carrying air emerges from the nozzles (6) towards the printed products moving past. If, however, a gripping device (2), which is part of the transport system (1) and which holds the printed product, enters the vicinity of the nozzles (6), a suitable control means (9 to 12) causes the nozzles to move into a second position.

Abstract: An ink supply unit for a receiving roller of a printing machine. The ink supply unit includes an ink rail mounted in close proximity to the surface of the receiving roller, and a plurality of ink reservoirs mounted one above the other in the ink rail that discharge differently colored inks in accordance with the printing requirements onto the surface of the receiving roller through a valve mechanism. Wiper rollers are mounted adjacent to the surface of the receiving roller to wipe the surface thereof to reduce ink wastage due to misting or the like. The inks are introduced onto the surface of the receiving roller and are mixed to form the required color for printing by the combined action of the wiper rollers and a roller train that links the receiving roller and the print roller in the printing machine.

Abstract: The invention provides a computer system utilizing bi-directional communication between a computing device and a printing machine, for transmitting data representing real-time supply roll parameters to an application program on the computing device. Supply roll parameters are stored on a memory circuit component that is connected to a supply roll. The computing device polls the printing machine for the supply roll parameters. The printing machine transmits the supply roll parameters to the computing device and the computing device formats the parameters into a display, proportionately matching the dimensions and color of the actual supply roll. A user can then create and/or edit output files for the specific supply roll loaded in the printing machine, viewing the output exactly as it will be printed.
