Title: Peripheral controller for i/o subsystem using slow devices
Inventor: CATILLER ROBERT DOUGLAS
IPC: G06F13/42
Filed: 1983-01-31
Granted: 1988-07-28
Abstract: the peripheral-controller is provided for use in an I/O subsystem which handles data transfer operations between a host computer and a number of peripheral terminals. The controller comprises a universal processor, which generates instructions and executes data transfer operations, and an application dependent logic module which particularly adapts the instructions to each peripheral terminal connected to the system. The controller is particularly adapted to recognise the use of slow memories or slow devices. Upon such recognition, control logic in the application dependent logic module controls the clocking of the universal processor to close down data transfer rates to operate within the slow devices.

Abstract: This invention is directed to the retreading of steel belted radial tires by removing and replacing more than the protector ply. Initially, the tire is inspected to determine if it is retreadable. The tire is then buffed so that the protector ply will be located and removed. The first working belt is then located and removed. A steel belt incapulated in uncured rubber will be placed on the tire. Then wedge stock will be applied, isolating the replacement belt. A second replacement belt will be applied for the protector ply with the steel cords going in the opposite direction of the first replacement belt applied. Precured tread rubber will be applied to the casing surface in the usual manner. The assembly is then covered by an envelope and a metal curing band will be applied to the outer surface. The assembly will then be mounted on curing rims and cured in commercially available equipment.

Abstract: A high-temperature resistant sealing gasket, adapted to be clamped between flanged pipe ends for service in a static environment, comprises a flat mica mat including, in a superposed relationship, a great number of mica scales, each formed of a plurality of stacked, extremely thin mica platelets held together by natural cohesion. The mica scales are oriented, with their largest opposite faces, essentially parallel to the opposite mat surfaces. The mica mat further includes a binder situated between overlapping zones of immediately superposed scales. Particular materials for the mica scales and the binder are selected such that the mica mat, in a non-installed state, has the property of undergoing, when heated, a thickness increase in a direction perpendicular to the largest scale faces. The thickness increase starts at a temperature of about 500 DEG  C. and reaches, at 800 DEG  C., 100% relative to the thickness at 20 DEG  C.

For this purpose, only one line module (3) is in each case provided for one subscriber and one exchange cable (7 and 9, respectively) which exhibits on the line side (18) an interconnection panel with contact elements (13, 14, 15), both for terminating the subscriber and the exchange cables (7 and 9, respectively) and in the interior the break point (12) arranged between the contact elements (13, 14) and switching through the circuit paths, and that the line module (3) is provided both on the line side and on the handling side (18, 23) with plug-in openings (19 and 21, respectively) for plugging in connecting plugs (6 and 5, respectively) on both sides into the break point (12). Thus, only a single line module (3) is needed for each pairing of subscriber cable (7) and exchange cable (9) so that a simple and compact construction is achieved with a low number of line modules (3). Should it become necessary later to change the allocation of a subscriber cable (7) to another exchange cable (9), a special connecting plug (5) is inserted from the handling side (23) into the line module (3) which is provided with terminal connections (32, 33) for patching wires (28). <IMAGE>
