Abstract: Abstract of the Disclosure A communication system for use in a network of interconnected communication paths such as electrical power lines utilized for distributing electrical power. The system includes two or more remote units and a master unit, each having an associated address, which are connected to the network.  The remote units are each capable of initiating a down link message sequence wherein a data package containing data, such as data relating to power consumption, is transferred from one of the remote units to the master unit.  The down link message sequence may include the transmission of one or more messages containing the data package by the remote units with the particular path taken being a function of network conditions.  The master unit acknowledges receipt of the data package by initiating an up link message sequence wherein the remote units transmitting during a down link sequence are informed of the receipt.  In addition to addresses and data package the messages include information regarding network conditions.  By way of example, a message may include information which indicates the amount of noise present in the message path between the transmitting remote unit and the master unit and information which indicates the number of message transmissions required to transfer a data package from the transmitting unit to the master unit.  Remote units ascertain network conditions for selecting optimum message paths by examining messages received on the network, including messages not directed to the receiving remote unit.

Abstract: A B S T R A C T                   ENERGY STORAGE AND RECOVERY      A method and system for underground storage and recovery of energy. A first fluid having a relatively high density is pumped from the bottom of a second cavern to the bottom of a first cavern filled with a fluid having a relatively low density by means of an overground pump/turbine apparatus, as a result of which the relatively low-density fluid is displaced out of the first cavern to the second cavern through an overground connection, filled with the second fluid. In order to retrieve the stored energy the low-density fluid is allowed to return to the first cavern displacing the high-density fluid to the second cavern, thus driving the pump/turbine.

Abstract: QUICK CHANGE ROTARY PUNCH                 Abstract of the Disclosure A quick change punch reel for a rotary press comprises a transversely split annular main body member having radially extending cylindrical sockets for receiving individual punches, each punch having a head and a base and an outer cylindrical sidewall with a circumferential undercut including a tapered wall extending toward the base of the punch.  The sockets are adjacent a planar side face of the main body member and cylindrical bores are formed through the side face in alignment with and intersecting the sockets with the bores having counterbores at the side face.  Punch retaining plungers are spring-biased into the bores and counterbores by means of a transversely split cap plate which is secured to the side face of the main body member.  Cylindrical punches may be exchanged in the sockets by retracting the plungers against the compressive force of individual springs such that the punches are received within the sockets and retained by spherical heads of the plungers within the undercuts of the punches. Preferably, the punches are retained with their bases fully seated within the sockets by the heads of the plungers engaging the tapered sidewalls of the circumferential undercuts of the plungers to exert an axial seating force on the punches.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved injection molding nozzle and a method of making it.  The nozzle has an electric heating element integrally vacuum cast in copper in spiral channels cut in the outer surface of the tool steel nozzle body.  The heating element has a cold terminal at one end which projects out through a hole in a head plate which is rotatable prior to casting to ensure the nozzle has a consistent length of heating element cast in.  A sleeve is located over the spiral channel prior to casting to ensure the heating element in the channel is covered with a minimum depth of copper to dissipate the heat from the heating .. element.  The spiral channel can be cut with a varying pitch according to a predetermined profile to provide more heat where there is more heat loss.  This forms an economical and durable nozzle with a large central bore which has high bursting strength and maintains the melt at a uniform temperature along its length.

Abstract: In the fitting of roofing panels 18, 19, especially ridge tiles, on the ridge of a roof constructed by mounting of corrugated roof slabs 14, 15 on a construction of wooden laths 10, 11, 12, 13, a filling part 29, 30 is used to produce a flat top side as contact for the roofing panels 18, 19. Between these roofing panels and the flat top side of the filling part, a weather strip 20, 21 is preferably fitted or cement or joint filler is applied. The filling parts 29, 30 can specifically be provided with ventilation holes 35 and can thus form ventilation inserts. Thanks to the flat top sides produced by the filling parts, it is possible to establish a simple, material-saving, stable and leak-tight connection between the roof slabs and the roofing panels. For mounting of the roofing panels 18, 19, use can advantageously be made of a mounting device 22 which has a corrugated holding member 24, designed to be able to receive and secure one end of the roofing panel 18, and an elongated anchoring part 26, designed for mounting in a hole 23 in the opposite end of the roofing panel 19 and for interaction with a plate-like holding member 28. A secure and stable anchorage of the roofing panels is thereby obtained. <IMAGE>

Abstract: An arrangement in nail driving machines having a nail magazine 6 and feed lines 7 for conveying nails 23 therefrom to one or more nail hammers 1. The latter comprise a pneumatic ram cylinder 8. The said cylinder 9 is connected to a compressed air source by way of a pressure valve 10, and the ram 12 thereof is connected to at least one driving bolt 13 This is displaceable forwards and backwards through a head 14, 31, which is a part of the nail hammer 1, and to which one or more feed lines 7 are connected. In order to specify a pneumatic nail driving machine, which operates with great force and speed despite a low operating air pressure, thereby requiring a less hefty frame construction than previously known nail driving machines, the valve construction comprises a control valve 11, which in response to a pressure pulse shuts off the air outlet line from the cylinder 9 and at the same time opens the pressure valve 10, as a result of which the ram applies a working force. When the pressure pulse ceases, the control valve 11 at the excess pressure still prevailing in the cylinder 9 is made to open the air outlet line again and close the pressure valve 10. A connecting duct 26, 32 carries compressed air down to the underside of the ram 12, so that this is brought back to the ejection position. <IMAGE>

During a period following on said first period a relative movement takes place between the conveyor belt and the casing(s), whilst during this period no sub-atmospheric pressure is exerted in the casings and no compressive force is exerted on the mixture by means of the rollers. <IMAGE>
