  • Patent number: 4129933
    Abstract: Wooden members are joined with sheet metal connector plates having integrally struck teeth projecting from one side. The wooden members are placed between first and second pressheads. A coiled composite of connector plate stock has first and second lengths of connector stock in juxtaposition and with intermeshing teeth. The first and second lengths of connector stock are unwound separately and oriented so that the teeth thereof point toward the wooden members to be joined. A cutting means associated with the pressheads cut connector plates from the stock and the plates are positioned on opposite sides of the wooden members and at the junctures to be joined. The pressheads press the plates into the wooden members. The connector stock is provided as a free coil and has the advantage that no spool, reel, or like supporting device is required. Further, the composite of connector stock has no teeth projecting from outer surfaces thereof.

  • Patent number: 4123914
    Abstract: An improved change of phase refrigeration system utilizing low compressor head pressures to maximize compressor efficiency, employing a relatively low temperature cooling medium to cool refrigerant gases, using a metering device which is operable at a relatively low pressure differential to feed condensate to the evaporator coil and providing additional controls to temporarily increase head pressure and thus condensate temperature when such increased temperature is needed for heat recovery or gas defrost. Because the proposed refrigeration system employs condensate at a relatively low temperature it may be necessary to enlarge the supply line for liquid refrigerant running from the condenser to the metering device to minimize evaporation of the condensate in the supply line. Further, it may be preferable to insulate the liquid refrigerant line so as to minimize premature evaporation of condensate in that line.

  • Patent number: 4121842
    Abstract: An expansion seal for use with a product pipeline which extends through a larger casing is disclosed. The seal may also be adapted to function as a coupling if a leak occurs in the product pipeline. The device comprises a cap having an axial opening to receive a sleeve which then surrounds the pipeline. The periphery of the cap is adapted to be welded to the casing end. The sleeve defines an internal circumferential recess which contains packing, and the sleeve carries means for compressing the packing into sealing engagement between the pipeline and sleeve. The device may function as a coupling by welding the sleeve to the pipeline.

  • Patent number: 4120167
    Abstract: The forward movement of a pipe-laying vessel when laying pipe offshore is controlled to maintain the position of the pipe as laid on the sea bed as close as possible to the desired track. The position of the touch down point on the sea bed of the pipeline suspended from the vessel is measured at periodic intervals by driving a survey vessel fitted with an echo location device along the already laid line. The measured position of a touch down point is compared with the desired track and any deviation is computed. Further movements of the pipe-laying vessel are adapted to minimize this deviation.

  • Patent number: 4119796
    Abstract: Disclosed is a device for automatically synchronizing incoming digital data with a local clock. Incoming clock pulses are compared with the local clock pulses after being delayed by a sufficient amount to produce synchronization between the incoming and local clock pulses. The incoming data pulses are delayed by the same amount as the incoming clock pulses so that they too are synchronized with the local clock. Both digital delays are variable and may be used to provide both fractional clock period delays or multiple clock period delays for accurate synchronization over a relatively long communications cycle.

  • Patent number: 4117645
    Abstract: An improved method for handling and transporting thermoplastic materials such as chewing gum base is disclosed. Chewing gum base, formulated as a hot viscous blend, is initially extruded and then pelletized. The pellets are subsequently cooled in a liquid medium such as water. Instead of drying the pellets and coating the pellets with a lubricating powder for packaging and shipment, a slurry of the cooling medium and pellets is conveyed to bulk containers or railroad tank cars for transport to the customer-user, a chewing gum manufacturer. By transporting in a liquid the tendency of the tacky pellets to agglomerate is eliminated, and the prior steps of drying and coating the pellets with a lubricating power are unnecessary. The customer-user, in the case of chewing gum base, furthermore, does not have to separate agglomerated pellets before use, and the pellets need only be strained and conveyed directly to a blender for formulation into chewing gum compositions.

  • Patent number: 4112695
    Abstract: The sea sled includes a pair of pontoons mounting depending rollers for straddling a pipeline disposed on the sea bottom. Water jets fluidize the sea bottom to form a trench in which the pipeline settles. The slurry formed by the water jets is removed from the trench by the eductor system which includes a pair of conduits each having a suction inlet at its lower end for location within the trench, a discharge at its upper end, a pair of pump nozzles each having an inlet external to the associated conduit and an outlet within the conduit directed toward the corresponding discharge, and a pair of primary nozzles, the outlet ends of which respectively project into the inlet ends of the pump nozzles. A high pressure, low volume, fluid is pumped from the surface through the jet nozzles. Ambient fluid is entrained with the high pressure, low volume fluid emanating from the jet nozzles in the respective pump nozzles to deliver low pressure, high volume fluid to their corresponding discharges.
