Abstract: Known screen printing machines, which have a continuous support for the squeegee, have the disadvantage that the printing is impaired when the support bends. This also applies to constructions with a squeegee support which is independent of the support and the weight of which, in the case of an asymmetrical squeegee arrangement, results in an uneven loading of the squeegee. According to the invention, the support is therefore disposed rigidly at the guide rails, and pneumatic double-action cylinders are arranged directly at the support, the squeegee being fastened at the cylinders so that its angle can be adjusted. A bending off the support does not influence the printing quality, even if the squeegee is not arranged in the center of the support.

Abstract: The invention is concerned with an orthotic fitting device and method. An envelope and an adjacent diverticulum are connected to one another and are filled with a known amount of a viscous fluid. The diverticulum has indicia on it capable of indicating what portion of the fluid is within the diverticulum. The envelope is fitted against a portion of a patient's body which is to be cushioned and the fluid adjusts between the envelope and the diverticulum to provide proper cushioning for the foot. Flow communication is stopped between the diverticulum and the envelope and the amount of fluid in the diverticulum is determined from the indicia. An orthotic device in the shape of the envelope is then formulated containing the amount of fluid which remained in the envelope of the fitting device.

Abstract: This invention relates to an aligning structure for aligning pin-receiving holes on a screen frame used in screen printing relative to upright pins mounted on a pin bar. The aligning structure, includes a pair of plates clamped on the frame. A first plate has an upright-pin-receiving hole to slidably receive the upright pin. A second plate has an upright-pin-receiving hole substantially larger than the upright pin. If the upright pin is received by both upright-pin-receiving holes and the clamp is loosened, the two plates can slide relative to each other to reposition the upright-pin-receiving hole relative to the screen frame. Retightening the clamp maintains the new alignment.

Abstract: An orthopedic appliance and method for changing the angular relationship of an individual's longitudinal axis of the lower lumbar spine to a longitudinal axis of the femorae which includes a support device having a lower surface to be disposed along a resting surface. The support device also includes an upper surface having first and second surface portions which are angularly disposed relative to one another. The first and second surface portions are to be applied against a front portion of an individual near the individual's lower lumbar spine and femorae. The angular relationship between the first and second upper surface portions recreates in an individual an angle between the longitudinal axis of the lower lumbar spine and the longitudinal axis of the femorae which is approximately equal to the angular relationship between these longitudinal axes while an individual is standing.

Abstract: A screen printing machine is disclosed which has a screen frame mounted on a swivel mount shaft. The swivel shaft for the screen frame extends through the center plane of the screen frame which extends perpendicularly with respect to the movement of the squeegee. Devices are provided which can raise the screen frame on both sides of the swivel shaft. By means of this construction, while the advantages of a compensation of errors are maintained, the screen printing machine may be used for movements of the squeegee in both directions. The new screen printing machine is particularly well suited for the printing of printed circuit boards.

Abstract: A dot matrix line printer is disclosed in which the amount of wear of an ink ribbon is measured by continuously compiling data representing impacting action of the printer as the printer prints.In a first embodiment, this is accomplished by initially determining a dot count based on the length of the ribbon and representing the maximum theoretical useful life of the ink ribbon and then decreasing the initial dot count as printing thereafter commences. The dot count remaining is continuously divided by the initial dot count to determine the percentage of ribbon life remaining. When the dot count has been decreased substantially to zero, a worn ribbon indication is provided to initiate an audible or visible alarm and to prevent further printing until the worn ribbon is replaced. As printing occurs the dots actually printed are counted, and this count is applied to reduce the initial dot count at a rate determined by the type of printing being undertaken.

Abstract: A vacuum blanket cleaning system is provided for removing dust, lint or ink from a blanket cylinder in an offset printing press during the uninterrupted course of a press run. Operation is effected by an air cylinder which periodically urges a brush against the blanket cylinder and retracts the brush from the blanket cylinder for replacement or maintenance. The action of the brush in combination with rotation of the blanket cylinder is such as to loosen dust and lint from the blanket cylinder, which dust and lint is then drawn into a vacuum system that surrounds the brushes.

Abstract: This invention relates to a resilient leg brace which acts in parallel with a runner's legs to support the weight during foot impact, to store the kinetic energy of vertical motion, and to release said energy thrusting the runner back into the air during take-off. The running brace is energy efficient in that it stores and releases the maximum amount of said energy, which means that the leg muscles do not need to supply as much energy to lift the runner's weight during each step. Also, the running brace protects the legs and other parts of the body from damage due to impact. The leg brace is attached to a pelvic harness, and optional back and neck braces are attached to the shoulders and the chin for the protection of the back and neck from impact shock.
