  • Triple integrated heat pump system
    Patent number: 4646538
    Abstract: A heat pump system with three heat exchangers, two of which are connected through a reversible expander and the third of which is connected to both of the first mentioned exchangers through an expander and check valve arrangement for refrigerant to flow from the third to either of the first two heat exchangers but not vice versa. A flow control valve selectively connects the other side of either of the first two heat exchangers to the suction side of the compressor while selectively connecting the other side of any one of the heat exchangers to the high pressure side of the compressor to form a refrigeration loop including two of the heat exchangers. Refrigerant flow through the heat exchanger not being used is blocked.

  • Packaging machine
    Patent number: 4642967
    Abstract: Apparatus for loading articles into trays where the articles are first separated into rows with a divider assembly, then separated into groups with a grouper assembly and then pushed onto a dead plate to form a load. Different divider and grouper assemblies are provided to make different load configurations. A tray blank is moved under the dead plate and pushed out from under the dead plate synchronously with the movement of the article load over the dead plate so that the article load is deposited on the tray blank. Thereafter, the flaps on the tray blank are folded to erect the tray around the group of articles. Mechanical folding mechanisms are provided to fold certain of the flaps on the tray without folding the other flaps. The method of loading the articles in the tray and forming the tray around the articles is also disclosed.

  • Guide mechanism for loading cartons
    Patent number: 4633643
    Abstract: The invention provides a loading finger for a drop loading mechanism which finger incorporates a guide plate. In a drop loading grid set the loading fingers define passageways through which bottles are dropped into the cells of cartons. In order to protect the partitions between adjacent carton cells during drop-loading, opposed loading fingers which are located in adjacent passageways have guide plates which include upper portions overlapped with one another above the uppermost edge of a carton partition during drop loading and include lower portions which are spaced apart one on either side of and below the uppermost edge of a carton partition.

  • Welding ring gauge
    Patent number: 4625414
    Abstract: A welding gauge for an insert ring on the end of a pipe with a first slide member defining a pipe engaging gauging surface and with a second slide member slidably mounted on a first slide member along a path perpendicular to the path of the gauging surface. The second slide member has a ring engaging recess which projects out over the gauging surface to hold the welding ring in place on the end of a pipe. The slide members can be locked together in any position for adjustment.

  • Double feed detection device
    Patent number: 4608856
    Abstract: A double feed detector to detect the feeding of multiple sheets into processing equipment such as printing presses which includes a reciprocally mounted gauge tube with a passage opening onto its opposite ends so that one of its ends is lowered into a gauging position over a support surface on which the sheets being fed are located. A pressurized air supply is connected to the gauge tube intermediate its ends and a cap closes that end of the passage opposite the end at the support surface so that, when more than one sheet is located on the support surface, the rise in air pressure in the gauge tube will urge the cap against a switch to stop the sheet feed to the processing equipment.
