Abstract: ABSTRACT               Weatherstrip is composed of a substrate having a pile strip upstanding from one surface thereof.  In one embodiment the substrate is made of two different materials, one of which is a thermoplastic material that is heat sealed by being passed over a heated bar to prevent the edges of the weatherstrip from fraying.  The other material maintains the structural integrity of the substrate during heat-seal-ing.  Essentially the whole of the undersurface of the sub-strate including the portion immediately beneath the pile strip contains the aforementioned thermoplastic material, making it possible for the substrate to be surface mounted on a component such as a door or window fabricated of a material compatible to the thermoplastic material.  In another embodiment the substrate may be composed entirely or partly of the thermoplastic material, and the same thermo-plastic material is extruded onto the back of the substrate.

Abstract: Reversing Mechanism for Curtain Type Route Indicator ABSTRACT     A helical driver gear is rotatable on a shaft driven by a reversable electric motor. The gear has a pair of helical gear followers attached to an arm freely rotatable on the driver gear shaft and adjacent the driver gear and in eccentric mounting there-with thereby to effect alternative engagement with either of two other helical gears, each mounted on the end of spaced apart curtain roll shafts which are parallel and equidistant from the drive shaft, instantaneously with change of torque of the driver shaft. The route indicator curtain can be controlled electrically and driven at high speeds without damage as each roll becomes a driver at the same instant the other becomes a free follower.

Abstract: SUMMARY OF THE INVENTION   The invention relates to, on the one hand, a method and on the other hand, a device for the rapid hardening of concrete and similar casting materials by carbonation. The method is characterized by forcing the capillary system of the material in the curing facility to be effectively dried out; prior to and/or during carbonation, by means of controlled conditions in the form of an air flow, heat generation and moisture absorption in a circulating, continous procedure.   The device for applying the afore described curing process is characterized by a hermetically closed unit which contains equipment for air circulation, heat generation as well as a control device for conditioning, connected to the close unit, by which the equipment units may be run individually or jointly, depend-ing on the composition, structure, geometry, etc. of the material to be cured.   Vacuum suction may also be connected to the device by the curing facility, when ever vacuum treatment is possible, i.e. in the case of a closed mould or a closed chamber. Total de-humidification of the casting material can take place provided air circulation, heat supply and de-humidification occur in a, with the casting material, completely closed system.

Abstract: A B S T R A C T     The digital switching module (DSM) is arranged as an LSI device providing digital (p.c.m.) switching for 256 channels in a space-time-space format.  It is undirectional in operation and is capable of switching data (digitally encoded speech) from any incoming channel to any outgoing channel.  It is arranged to act as a building block in constructing larger digital switching networks.  The DSM can be programmed to permit combinations of parallel or serial operation at its input and output data interfaces, the mode being selected by the size of the pulse width of the frame start reference signal.  The switching configuration of input channels to output channels is held within the DSM and can be amended by messages sent along a serial control interface.  Interrogation of the switching state and of the data passing through the switch is provided by messages applied to an output control interface.  The DSM can be arranged into square arrays to provide full availability switching for a greater number of channels. Three programming pins are provided which influence the control logic of the DSM to route the control information incoming to a square array to the appropriate control store.  The array may be grown from 8 x 8 to 16 x 16 and to 32 x 32.

Abstract: FEEDBACK WELDER CONTROL SYSTEM                    Abstract of the Invention A control system for resistance welders of the type in which welding current is supplied to a workpiece through a transformer.  The system assures weld quality by monitoring the change in resistance across the weld during the welding operation without the need for auxiliary leads or separate sensing transducers at or near the workpiece and automatically terminates the welding current when a quality weld is made as determined by weld resistivity characterstics.  To accomplish this, the system monitors the discrete changes in the characteristics of the current in the primary of the welding transformer which occur as a result of changes in weld resistance.  Immunity to line voltage disturbances which can cause changes in current characteristics unrelated to resistance change in the weld is achieved by a modeling circuit which is subjected to the same line voltage disturbances as the actual welder circuit and which simulates the current characteristics of the actual welder but is unresponsive to the resistive changes which occur across the weld during the welding operation.  The system compares the current characteristics of the modeling circuit with those of the actual welding circuit and terminates the welding current in response to the true resistance change which occurs during weld formation.

Abstract: Abstract of the Disclosure A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing includes two redundant interprocessor buses dedicated exclusively to interprocessor communication.  Any processor module may send information to any other processor module by either bus.  The buses are shared in use by the processor modules on a time-sharing basis.  Use of each bus is controlled by a special bus controller.  The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor modules. Each device controller includes logic which insures that only one port is selected for access at a time.  The multi-processor system includes a distributed power supply system which insures uninterrupted operation of the remainder of the multi-processor system in the event of a failure of a power supply for a part of the system.  The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller.  Either one of the two power supplies provides the entire power for the device controller in the event the other power supply fails.          The distributed power supply system permits any processor module or device controller to be powered down so that on-line mainten-ance can be performed in a power-off condition while the rest of the multiprocessor system is on-line and functional.  The multiprocessor system includes a memory system in which the memory of each processor module is divided into four logical address areas -- user data, system data, user code and system code.  The memory system includes a map which translates logical addresses to physical addresses and which coacts with the multiprocessor system to bring pages from secondary memory into primary main memory as required to implement a virtual memory system.  The map also provides a protection function.  It provides inherent protection among users in a multiprogramming environment, isolates programs from data and protects system programs from the actions of user programs.  The map also provides a reference history information for each logical page as an aid to efficient memory management by the operating system.          The multiprocessor system includes in the memory of each processor module an error detection and correction system which detects all single bit and double bit errors and which corrects all single bit errors in semiconductor memory storage.
