Abstract: ABSTRACT OF THE DISCLOSURE A preassembled press fit connector and method of mounting the same on a printed circuit board in an array of plated thru holes comprises a selectively configured connector housing and first and second adjacent rows of contacts mounted within the housing. Each contact has a press shoulder portion within the housing and a press fit section extending downwardly below of the housing.  A removable insert includes a plate portion for defining an external connector press surface above the housing and first and second rows of integral teeth extending downwardly into the housing. The rows of teeth engage one each with the press shoulder portions of the first and second row of contacts.  This allows the press fit sections of the contacts to be simultaneously forced into mating engagement with the plated thru holes of the printed circuit board by applying pressure to the connector press surface.

Abstract: ABSTRACT     IMPROVEMENTS IN OR RELATING TO COMPUTER OR PROCESSOR                 CONTROL SYSTEMS     A processor control system for controlling items of hardware includes pairs of processors associated with the hardware items.  One processor of each pair operates the process or processes for controlling the associated hardware, whilst the other processor of each pair operates other processes.  In the event of a fault in one processor the processes on that processor are transferred to spare processors and the hardware control process is transferred to the other processor of the pair.  This arrangement makes more effective use of standby processing capacity.

Abstract: Abstract of the Disclosure An improved concrete railroad tie having a rail-securing plate affixed at each end is provided which is easily and inexpensively adaptable to differ-ent railroad gauges and rail dimensions.   Each plate has one or more apertures at each end thereof and also includes  a pair  of  spaced-apart,  upstanding eyelets secured to one face of the plate and configured for receiving a rail fastening clamp.  The spacing between eyelets and the position of the eyelets on the plate is determined by the gauge and rail dimensions of the intended application.  The concrete railroad tie has a number of elongated,  tubular inserts imbedded in the concrete such that with the plate in place on the tie the apertures and inserts are aligned.  The inserts are square in cross-section and include a number of intru-sions in opposite walls of the insert.  The plate is secured to the tie by driving a standard railroad spike through the plate aperture into the  insert with the intrusions seizing and securing the spike.  Advantage-ously, this design allows concrete ties to be standar-dized and plates varied according to the gauge and rail dimensions desired.

Abstract: A replaceable inspection plug assembly and method for its use with pressure vessels. The plug assembly comprises a collar seal welded onto a pressure vessel outer wall, and a threaded plug removably threaded into the collar and the vessel wall. The plug has a shoulder portion which is seal welded to the collar. For removal of the plug, the seal weld is first machined away using a special cup-shaped rotary machining tool. The plug is then cooled and contracted relative to the collar, and is then unscrewed and removed. Following inspection of the vessel interior, the plug is replaced in the threaded hole and the plug shoulder portion is rewelded to the collar to provide a structurally-rigid and leak-tight joint without need for subsequent stress relieving the welded joint.

Abstract: A B S T R A C T            For the manufacture of a nut, a piece of plate mat-erial which is bent to form a tube (9) can be used. This tube can be placed over a mandrel (8) and clamp-ed together around the mandrel, first by means of a pair of spring-loaded dowels (5) and thereafter by two clamping jaws (1, 2). When the mandrel is then withdrawn, a thread-forming tap (12) during rotation in the direction of the thread can be pressed in through the tube to produce an internal thread by deformation. When the tap has passed right through the tube, the direction of rotation is reversed and the tap is screwed out again, after which the nut is finished.            For cooling and lubrication, cutting oil is supplied to the tap before insertion into the tube and possi-bly to the inside of the tube.            There can also be used a tap with a shank (13) which functions as the mandrel (8), and at one end of which extends the threading piece (14). In this way the thread is formed when the tap is turned against the direction of the thread, i. e. turned out of the tube, whereby the necessity of having to feed the tap through the tube more than once is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE Signal separation arrangements are provided for separating frequency interleaved signal components of a video signal one of which is modulated as a double sideband modulated component of a subcarrier frequency.  A video signal is sampled by a digital-to-analog converter. The resultant signal samples are applied to a bandpass filter.  The bandpass filter produces a filtered signal restricted to a given passband of the original video band over which the double-sideband-modulated component is modulated.  The filtered information in the passband is comb-filtered by a comb filter operating on selected ones of the bandpass-filtered samples in response to a subsampling clock signal.  The subsampling clock frequency is less than or equal to the subcarrier frequency.  The comb filter comprises a shift register and a signal combining circuit.  Comb-filtered samples, produced at the subsampling clock rate, correspond to one of the interleaved signal components.

Abstract: ABSTRACT OF THE DISCLOSURE     A plurality of standardized curtain wall units of rectan-gular shape are arrange in rows and columns, with a predetermined gap between the opposed side frame members of every two horizontal-ly adjoining curtain wall units.  For closing the gap so as to allow relative displacement of the individual curtain wall units in their own plane, a sealing band of elestic matrial has its lateral marginal edge portions engaged in a pair of opposed mount-ing grooves in the opposed side frame members of every two hori-zontally adjoining  curtain wall units.  The sealing band has a width less than the distance between the bottoms of the pair of opposed mounting grooves in which the sealing band is engaged.          Thus assembled unit type curtain wall assembly has a room tempera-ture control function, with passageway for conditioning air and hot or cold water extending longitudinally through the side frame members of each curtain wall unit.  The gap between any two such side frame members is closed by three sealing bands, one on the indoor side of the gap and the other two on the outdoor side of the gap.

Abstract: A CONVEYOR SYSTEM FOR A SHOT PEENING MACHINE               Abstract of the Disclosure A conveyor system is for a shot peening machine of the type which includes blast wheels which are capable of propelling shot generally downwardly into a critical blast region for shot peening a plurality of springs passing therethrough.  The springs are supported on horizontally extending spinner rolls within the critical blast region to be capable of being conveyed along a horizontal peening path therethrough.  The conveyor system includes a plurality of finger elements extending horizontally into the critical blast region above the spinner rolls and transversely of the peening path.  Each finger element includes a first end for making contact with one of the springs and a second end which is secured to and supported by a continuous chain located remotely of the critical blast region.  The finger elements are mounted on the chain a predetermined distance apart to be capable of receiving a single spring therebetween.  The continuous chain is mounted in a horizontal loop between an idler sprocket and a driving sprocket to advance each finger element and cause it to be extended into the peening path to convey one of the springs therewith through the critical blast region.  Each finger element will extend through and be advanced along a horizontally extending slot in a wall separating the critical blast region from the continuous chain.
