Abstract: ABSTRACT OF THE DISCLOSURE   The present invention is a means to race two or more conditions against each other to trigger a unique control response. In particular, a portion of a machine control is suspended upon the occurrence of conditions such as an input, a time delay, availability of data, or completion of a task.  These conditions race against one another. That is, the occurrence of one of the conditions will initiate the response, and all other conditions will then be ignored. The type of response depends upon the particular condition that occurred first.

Abstract: ABSTRACT     The present invention provides a plug in wire terminal system for a lamp socket.  The system includes a bushing mounted in a passage through the base wall of the socket and a terminal gripping the lead of a connecting conductor that is adapted to plug into the hollow core of the bushing.  The terminal is permanently mounted in the bushing by way of an outwardly biased cone portion that includes a plurality of biasable side strips that snap out once the cone passes an internal shoulder in the core of the bushing.  The terminal has a biased contact portion that electrically connects the terminal with the bushing.  The bushing includes a flared inner rim that both holds the bushing in place and electrically connects the bushing to a bottom flange extension of the screw shell mounted in the socket.

Abstract: ABSTRACT OF THE DISCLOSURE         In order to produce a double-wall composite metal pipe, a pipe assembly made up of an outer pipe of carbon steel and an inner pipe of stainless steel inserted in the outer pipe is caused to advance relative to a plastic working device such as die or a series of rollers.  Before the pipe assembly is caused to pass through the plastic working device, the outer pipe is heated to cause it to expand while the inner pipe is cooled to establish a temperature difference between the outer and inner pipes.  The heated outer pipe is constricted by device of the plastic working means and caused to plastically contract against the outer surface of the inner pipe, while the cooled inner pipe is subjected to expanding force of a mandrel inserted in the inner pipe, the mandrel backing up the pipe assembly from within the inner pipe against the constricting action of the plastic working device.  The pipe assembly thus subjected to the action of the plastic working device is cooled from the outside whereby the outer pipe is caused to shrink to firmly bind the inner pipe thereby to obtain an interference fit between the pipes.

Abstract: Abstract of the Disclosure Devices for interconnection into a digital computer system contain arbitration mechanisms for assigning control of a common communications path among the devices.  Several modes of device arbitration are provided for, and the modes may be mixed among devices, and changed during operation of the system, in the system without interfering with communications.  The arbitration mechanism requires only a single additional line in the communications pathway, and thus a single additional pin on the integrated circuit on which it is implemented, for the arbitration function.  It thus facilitates implementation of the arbitration mechanism along with all other interconnect logic on a single integrated circuit.

Abstract: Abstract of the Disclosure In the method and device for separation of harmful sub stances from a flue gas, in an absorption-heat exchanger arrangement both washing and also cooling of the  flue gas is carried out, the flue gas being cooled below the dew point and this cooling process taking place by means of exterior air in counter flow.  The flue gas is divid-ed during its passage through the heat exchanger into at least two parallel part flows of which the  first part flow  is directed into a  first  treatment  zone and the second part  flow  is  directed  into a  second  treatment zone.  The two treatment zones are connected parallel to one another.   In the first treatment zone a  first ab-sorption liquid is  introduced into the  flue gas which effects extensive removal of harmful substances from the flue gas  (gas cleaning), whilst in the second treatment zone a second absorption liquid is  introduced into the flue gas, in which second absorption liquid the precipi-tated harmful substances are soluble  (plant cleaning).          These two treatment zones are cyclically exchanged.
