Filed: 1977-11-25
Abstract: A hevy duty, retractable, hydraulic, telescopic shock absorber of the type employed on fire engines, artillery vehicles and the like includes a valve arrangement for venting the main cylinder to hold a floating absorber piston in any working position. The shock absorber includes a passageway between a damping fluid reservoir and the cylinder chamber. The passageway is in open communication with the cylinder chamber when the floating piston is in an extreme position. A valve closes the passageway when the floating piston is in a position other than the extreme position.

IPC: H03M13/00
Filed: 1977-12-16
Abstract: A parity checking scheme for detecting memory array word line failures whereby all of the data and parity bits of a plurality of bytes sharing the same word line erroneously assume the value "1" or the value "0". When storing data in the array, the data and parity bits comprising each byte are stored directly except for the parity bit of a selected one of the bytes, which parity bit is inverted by a gated inverter circuit before storing. The same gated inverter circuit also inverts the parity bit of the selected byte upon reading the stored data. All of the remaining bits of all of the remaining bytes are read directly. The read bits of each byte are applied to a respective parity checking circuit of the same even or odd parity type as is used in storing the data. The outputs of all of the parity checking circuits are applied to error control logic.

Abstract: A machine for packaging articles in continuous tubular material, which may be formed by rolling the marginal edges of a flat web around a succession of the product articles to bring the marginal edges into contact and then sealing them continuously to complete the tube, comprises a pair of transverse sealing jaws 14 and 1 which each include a hemi-cylindrical chamber 24 having gas-pervious walls 16 and defining a cylindrical space 25 initially centrally divided by the film between two successive product articles 1.The film extending diametrically across the space 25 is first of all severed and then suction is applied to the gas-pervious walls 16 to draw the film into contact with the walls 16. To the righthand side of the space 25 is a double impulse sealing system 18, 19 centrally divided by a knife 21 which separates a righthand pack 28 from the film in the space 25, and to the lefthand side of that space 25 is a further double impulse sealing system 18, 20, again with a knife 22 to effect separation. The sealing pads 20 at the lefthand side are movable by means of push rods 27 so that initially they allow the pack 8bto be communicated with the space 25 while the pack 8a has been separated from the space 25, and this enables gas from within the pack 8b to be extracted by way of the hemi-cylindrical chambers 24 and the suction conduits 17. Subsequently the two sealing pads 20 are pressed into contact with their counterpressure pads 18 and the righthand side of the pack 8b is then isolated from the space 25.

Abstract: A recording medium with a multicolor high resolution pattern created by layer packs. Pattern-forming layers of the layer packs are successively applied by photolithographic means in a sequence corresponding to a color of the high resolution pattern. The pattern-forming layers of the layer packs are separate from one another on the substrate of the recording medium. The process for producing the recording medium includes applying a photoresist layer to a substrate and developing the photoresist. Pattern-forming layers are successively applied over the whole surface of the substrate in a sequence corresponding to a color. The remaining photoresist and the layers overlying it are removed to leave a sequence of pattern-forming layers on the substrate separate from any adjacent pattern-forming layers.

Abstract: The invention relates to a printing blanket which has a non-uniform profile, and to a method for its application. Owing to the variation of the profile of the blanket cylinder (14, 16) and/or of the blanket (18, 20), either in relation to its material properties or in relation to its thickness, the blanket (18, 20) which is tensioned on a blanket cylinder (14, 16) corrects any undesirable changes in the speed profile of the web. If such changes in the speed profile are ignored, this can lead to creasing in the web, moving in a printing machine over the blanket cylinder, and thus have a considerably adverse effect on the register accuracy of the printing images. In a further design of the invention, a blanket cylinder is provided with a non-uniform profile (18'). <IMAGE>

Abstract: A method and apparatus for separating target particles from a mixture of target and non-target particles. The apparatus includes a vessel having an inlet through which the mixture may be introduced and an outlet through which the fluid may exit, at least a portion of which is pliable; a bed of binding material disposed within the vessel, the binding material attracting the target particles such that the target particles may become bound thereto and being porous enough to allow the non-target particles to pass therethrough; and a screen disposed below the binding material for retaining the binding material in place. The pliable portion of the vessel permits the user to separate the target particles from the binding material by merely squeezing the pliable portion in such a manner as to cause relative movement in the binding material, thereby creating the necessary degree of agitation to cause the target particles to become dislodged from the binding material. The deformation of the pliable vessel can be accomplished by either the user physically squeezing the vessel with his/her hand or using an external apparatus that applies the necessary force to the vessel.
