Patent number: 4206009Abstract: The invention relates to the formation of a tire tread profile by the application of rubber tread material upon a tire casing by employing a micro-computer programmer in conjunction with a tread material applicator apparatus. The control system employed during tread formation uses a programmer having a micro-computer unit, a floppy disk and a keyboard, interfaced with a tread material application apparatus.In operation, the programmer is connected to a drive motor of the tire tread application assembly and operates under the control of a tire profile program stored in the floppy disk. Proper tread profile shape is arrived at as a function of the digital ratio between the actual position of the tire rotation and the transverse position of the tire tread applicator assembly. The latter is digitally controlled within the parameters of a preprogrammed set of commands, as a direct and sole function of the position of the tire casing about its spin axis.Type: GrantFiled: June 26, 1978Date of Patent: June 3, 1980Assignee: AMF IncorporatedInventor: Richard E.

The shaft assembly is slidable within holes in the frame sideplates (71, 73) and within curved surfaces of projections (66, 67) of the paper guide body (28).Type: GrantFiled: November 1, 1978Date of Patent: April 8, 1980Assignee: Teletype CorporationInventors: Alexander Druschitz, Ingard B. Hodne

Patent number: 4189078Abstract: A mechanism is provided for securing a paper driving tractor device along a relatively thin elongate member effective in the released condition to permit the tractor to be positioned at will along said elongate member while in the locked condition enabling, positive, secured, engagement of the tractor with said elongate member effective to prevent any movement of the tractor relative to said member, also permitting locking an elongate member repeatedly at the same position without affecting the original characteristics of the elongate member.Type: GrantFiled: March 17, 1978Date of Patent: February 19, 1980Assignee: Burroughs CorporationInventor: Albert S. Spisz

Patent number: 4175689Abstract: A strip control system and steering roll which may be utilized in a rolling mill. The steering roll, having a semi-cylindrical outer shell, contacts a strip or web of material being processed. A degree of axial freedom is provided each half of the outer shell. A sensor capable of detecting strip or web off tracking is linked to at least one actuator which may impart an axial force to the outer shell to realign both the shell and material thereon. An opposing spring mechanism acts upon a traverse guide to automatically recenter the outer shell portion not in contact with the material being processed.Type: GrantFiled: August 25, 1977Date of Patent: November 27, 1979Inventor: Calvin E. Parker

Patent number: 4048861Abstract: A rotating body, such as a pulley or a guide wheel, is oscillatable along its rotational axis. The rotating body is carried by a longitudinal support having a cam surface extending generally perpendicular to the rotational axis. The support is mounted for rotation with a supporting shaft and is biased along the rotational axis so that the cam surface engages a stationary cam follower. Rotation of the shaft, support, and body relative to the cam follower results in the oscillation of the rotatable body.Type: GrantFiled: February 2, 1976Date of Patent: September 20, 1977Assignee: Johns-Manville CorporationInventors: Richard Paul Woidke, Thomas Joseph Wester, Eric Joseph Brosch

Patent number: 4027765Abstract: A plurality of printing stations are spaced across a machine wherein a feed or drive assembly for paper or like record media is associated with each station, each of the feed or drive assemblies being self-contained and of modular construction to enable positioning of an assembly in any desired location along a drive shaft. One drive mechanism includes a clutch member and associated drive gears and rollers to incrementally advance receipt paper in one direction, a second drive mechanism includes the clutch member and additional drive gears and rollers to advance journal paper in said one direction for rewinding and storage thereof in the machine, and a third drive mechanism includes the clutch member and further drive gears and rollers to advance slip or form paper in the opposite direction.Type: GrantFiled: July 31, 1975Date of Patent: June 7, 1977Assignee: NCR CorporationInventors: Leslie L. Crump, Victor J. Italiano

Patent number: 3942697Abstract: In hot strip rolling apparatus a driving roll stand is located between a rolling stand for producing the hot strip and a strip take-up reel. The driving roll stand comprises a pair of rolls capable of axial floating movement during take-up of the strip on said reel. A control system provides that the pair of rolls are locked axially when the strip tension between the rolling stand and the pair of rolls ceases.Type: GrantFiled: July 31, 1974Date of Patent: March 9, 1976Inventor: Klaus Neumann

Patent number: 3941288Abstract: An apparatus is described for positioning a paper web with respect to the print mechanism of a high speed printer. The apparatus includes a rod supported by the main frame of the printer and a slide tube is coaxially positionable on the rod. A pair of tractors for driving the web across the print station are carried upon the slide tube. One of the tractors is fixed to one end of the slide tube and the second tractor is positionally adjustable upon the slide tube. A clamp is provided for securing the second tractor to the slide tube after the spacing between the tractors is adjusted in relation to the width of the paper web. The slide tube is positioned to locate the type margin on the web at the desired location and a second clamp secures the slide tube to the rod.Type: GrantFiled: December 18, 1974Date of Patent: March 2, 1976Assignee: Teletype CorporationInventor: Robert R.
