Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides an arrangement for transmission of certain clock signals in a series of clock signals by means of signals of lower frequency compared to the frequency of said series of clock signals.  From said signals of lower frequency well-defined pulses are extracted for controlling logic equipments located distantly from the clock pulse source.  The arrangement includes at the sender side a clock pulse generator producing said series of clock signals, a counter which is stepped by said series of clock pulses and produces at least two, relatively to each other phase displaced, pulse series where the length of the pulses of said pulse series is a multiple of the length of the pulses of the first mentioned clock pulse series.  The phase displacement between said at least two pulse series corresponds to half the length of the pulses of said clock pulse series.          The frequency of said at least two pulse series is lower than the frequency of said clock pulse series.  The arrangement also includes two transmitters for transmission of said two pulse series.  At the receiver side the arrangement includes two receivers for receiving the two pulse series transmission through the line, a logical circuit detecting the two phase displaced pulse series and depending on a defined ratio between the amplitudes of the two signals, delivering a pulse during the duration of said defined ratio.

Abstract: ABSTRACT       Heat-recoverable articles, especially heat-shrinkable tubular articles, having an open end are formed so that the section adjacent said open end has a lower recovery ratio than a section adjacent thereto, thereby substan-tially reducing the risk of splitting when the degree of recovery is high or in applications where a high degree of unrecovered strain remains after recovery about a substrate such as a supply line.  A preferred article is a tubular cap which has an open end section having a first expansion ratio, an intermediate section having a second expansion ratio and a closed end section having a third expansion ratio, the second expansion ratio being greater than the first and third expansion ratios.  Such a cap may be employed to seal a conduit against ingress of moisture and other contaminants.  When a supply line is subsequently to be passed through the conduit the closed end may be removed and the article shrunk to grip the supply line.

Abstract: KEYHOLE GROUNDING CLAMP                ABSTRACT OF THE DISCLOSURE           A lightweight, grounding clamp assembly utilizes a grounding stud for rigid mounting on an elec-trical device and incorporates nondeformable, stud-engaging bight which renders the assembly capable of safely conduc-ting extremely high fault currents in the order of 100,000 amps or more.  The bight forms a part of an open-ended passage extending through the clamp body which passage is completely encircled by the body to resist distortion of the bight under the influence of high fault currents. In pre-ferred embodiments, the passage has a keyhole-shaped cross-section and the stud is configured to be complementally received and retained within the neck of the keyhole.

Abstract: Abstract A variable cycle turboshsft engine includes a remote fan system and respective high and low pressure systems for selectively driving the fan system in such a manner as to provide VTOL takeoff capability and minimum specific fuel consumption (SFC) at cruise and loiter conditions. For takeoff the fan system is primarily driven by the relatively large low pressure system whose combustor receives the m tive fluid from a core bypass duct and for cruise and loiter conditions, the fan system is driven by both a relatively small high pressure core and the low pressure system with its combustor Inoperative. A mixer is disposed downstream of the high pressure system for mixing the relatively cold air from the bypass duct and the relatively hot air from the core prior to its flow to the low pressure turbine.

Abstract: ABSTRACT OF THE DISCLOSURE           Material to be mixed is fed into the upper portion of a container from where the material descends by means of the force of gravity.  The container is provided with a partition extending across the interior of the container and operative to divide the descending material into at least two compartments giving at least two separated substreams.   The container is further provided with outlets for the compartments, and means for varying the cross sections of the outlets so as to separately control the respective rates of descent of the material of the two substreams in the container.  The material which is with-drawn at the lower portion of the container is returned back to the upper portion of the container through a riser pipe for further mixing.  Because of the two substreams in the container, the relative elevations of arbitrarily selected samples, located in respective ones of the substreams, change during material descent, thereby improving mixing action.

Abstract: ABSTRACT OF THE DISCLOSURE           Pipe components, i.e., pipes, fittings and valves, made of weldable plastic, are connected to each other by means of electrically welded joints.  The welding process is made possible by the fact that a welding collar is connected to the output of the welding device.  A power monitor permits the switching on of a switch stage of the welding current circuit.          Thermal energy is generated by squaring the welding or the line voltage in a pulse generator which produces a pulse frequency that is dependent on this value.  The pulses of this pulse fre-quency are summed in a counter.  Once a count value that corres-ponds to the thermal energy has been reached, the switch stage is switched off.  In the event that the count value is not reached a function monitor generates a warning signal.

Abstract: TIME TO GO AND DIAGNOSTIC DISPLAY FOR ELECTRONIC SEQUENCE TYPE APPLIANCE CONTROLLER                   ABSTRACT OF THE DISCLOSURE     An electronic sequence type controller for appliances or the like which provides numerical indications of how much time will be re-quired to execute a program cycle which a user has selected, and how much time is remaining as an operating cycle proceeds.  Additionally, means are provided for a service technician to rapidly set the controller to a particular program step for diagnostic purposes.  More specifically, after user cycle options have been inputted, control logic initially enables a counting and display means to count up and rapidly executes the entire selected program a first time, the rapid first execution appear-ing essentially instantaneous to the user.  This presets the counting and display means with a representation of the total number of program advancing operations required to execute the selected program.  Next, the control logic means enables the counting and display means to count down, and executes the selected program a second time with relatively longer intervals between successive program advancing operations.  The counting and display means then provides a continuous representation of the remaining time to go during the second execution.  For diagnostic purposes, the control logic has a diagnostic mode wherein the program is advanced incrementally a step at a time in response to manual actua-tion of a switch.
