Abstract: ABSTRACT OF THE DISCLOSURE     An expansion joint seal for use preferably in walkways and the like having a pair of elongated, parallel spaced-apart slab members defining a gap therebetween with each of the slab members having a generally C-shaped cavity opening toward said gap.  The seal includes mounting beads on each of its longitudinal edges for assembly within the aforesaid slab cavities and an intermediate section spanning the aforesaid gap and being attached to the mounting beads.  Each mounting bead is of tubular construction  and includes an outer wall surface configuration generally adapted for matching engagement with said cavity.  The radius of curvature of each mounting bead outer wall portion in an unstressed, disassem-bled condition is less that the radius of curvature of the corres-ponding cavity so that upon assembly of the mounting bead within the cavity the outer wall portion is forced to assume the curva-ture of the cavity resulting in a highly effective mounting of the bead.  The intermediate section includes a plurality of obliquely disposed crossbars joined together in a pantograph arrangement.          The intermediate section further includes a corrugated top wall disposed generally flush with the horizontal surfaces of the slab members and a corrugated bottom wall whereby vertical movement of the top surface of the seal is minimized due to the pantograph arrangement of the crossbars as the seal undergoes expansion and contraction.

Abstract: ABSTRACT OF THE DISCLOSURE         A  gas  valve  assembly  has  a main valve connected between the inlet and outlet and  controlled  by  a  diaphragm actuator. A two position control valve connects the upper side of  the  diaphragm  to  either  the  inlet gas pressure or the outlet gas pressure  to  open  or  close  the  main  valve.  A pressure  responsive  valve  means  responding  to  the outlet pressures, controls the exhausting of gas from the upper  side of  the  diaphragm to regulate the outlet pressure. An orifice is contained in the inlet passage to the control valve so that when the control valve is in an on position, the flow  of  gas to  the  upper  side  of  the  diaphragm is restricted by the orifice. To insure an initial fast opening of the  main  valve to  insure  ignition  of the combustion device, a flow control valve means is placed in series with the orifice  to  increase the  flow rate of gas when the control valve is moved from the off to the on position to fill the chamber above the diaphragm quickly. The flow control valve closes as soon as the pressure builds up on the upper side of  the  diaphragm;  however,  the delay  in the operation of the flow control valve provides for an initial fast opening of the valve means  when  the  control valve is operated.

Abstract: ABSTRACT OF THE DISCLOSURE      A fastener chain being fed along a predetermined path is brought to a temporary standstill each time an actuating pawl, engaged by one of the successive spaced pairs of interengaged scoop groups of the fastener chain, is displaced a predetermined distance therewith to actuate a limit switch.  A separator mechanism responds to the actuation of the limit switch to spread one of the succes-sive pairs of opposed blank tape spaces of the fastener chain to an extent necessary to partly disengage the preced-ing or succeeding pair of scoop groups.  The fastener chain is then moved along the path, either rearwardly or forwardly, to such an extent that the disengaged endmost scoops of the partly disengaged pair of scoop groups come into abut-ment against a stop disposed adjacent to a die.  A punch mechanism coacts with the die to apply a pair of top stops to the endmost scoops.  The above cycle of operation is repeated to attach top stops to the trailing or leading ends of the successive pairs of scoop groups.

Abstract: ABSTRACT         Disclosed is a splicing device for light-wave-guides, using splicing elements which guide the ends of the light-wave-guides to be united into centering grooves.  Retaining devices, arranged at each end of the splicing element, secure the ends of the light-wave-guides to be united and hold them at an acute angle to the base of the splicing element.  The ends of the light-wave-guides are introduced into the splicing element by relative movement between the retaining devices and splicing element, the ends of the light-wave-guides being thus moved towards each other in the centering groove of the splicing element J and being brought into contact and secured.  The retaining devices for the light-wave-guides to be united are designed to pivot in an imaginary plane until they are in mutual alignment.  The centres of rotation of the retaining devices, which allow them to pivot are located below the plane in which are situated clamping elements for the ends of the light-wave-guides and for the sheaths thereof.  The retaining devices have clamping elements for the light-wave guides as well as clamping elements for the sheaths of the light-wave-guides and the carrier for the splicing elements is arranged between the reatining devices and is adapted to move towards them.  The device provides a means whereby a linear junction can be produced in a simple manner.

Abstract: ABSTRACT           An electronic control system for controlling a sequence of operations on products moving on an indexing conveyor.  The electronic control system is illustrated as controlling a sequence of operations, carried out at various work stations, on cartons in a packaging machine, such as filling operations, sealing operations, and clean-in-place operations on carton filler heads.  A limit switch carton detector detects the presence or absence of cartons on the indexing conveyor of the packaging machine and feeds such carton information into a first shift register, which in turn feeds the carton position information into a first "and" gate.  A limit switch machine timing indicator functions to feed a first machine timing signal into said first shift register, and into a machine cycle counter.  An output signal from the machine cycle counter is fed into a sequence selector which produces a sequence signal that is fed to said first "and" gate, which in turn produces a filler sequence signal.  The carton position information from said first shift register is also fed into a second shift regis-ter, and together with a second machine timing signal produced by a second limit switch machine timing indicator, produces a second shift register output carton position signal that is fed into a second "and" gate.  The last mentioned second machine timing signal is also fed into an overtime timer which produces an output signal that is also fed into the second "and" gate, and the output from the second "and" gate produces a sonic sequence control signal for controlling the sonic sealer head on the packaging machine.  A limit switch machine mechanism position indicator produces a machine mechanism position signal which is fed into a C.I.P. sequence timer which produces an output signal that is fed into the sequence selector to provide an output signal to the first "and" gate which produces a filler sequence control signal when the packaging machine is not running.
