Abstract: In connection with a beverage dispensing machine, an automatic self-fill control apparatus for the machine for controlling the filling of the liquid tank, which liquid tank is fed with a combination of water and a concentrate syrup adapted to be mixed with the water within the tank. A sensor member is disposed in the tank in a position so as to be responsive to the rise and fall of liquid in the tank. Pump means are provided adapted to pump the syrup to the tank. Control of water flow to the tank is also carried out. The sensor member has a low probe for detecting a low predetermined level of liquid in the tank and a high probe for detecting a high predetermined level of liquid in the tank and adapted to respectively generate low and high probe signals. Control circuit means is provided receiving and responsive to these low and high probe signals for controlling the pump to operate when the low probe is uncovered and terminating the pumping action when the liquid level reaches the high probe position so that the liquid level in the tank is always maintained at a level between the low and high probes. Also provided is a third sensor for determining an unsafe condition referred to herein as a system override to shut the system down in the event that the high probe is covered and that the liquid level proceeds to the even higher third probe. Also in the system of the present invention, there is provided a sensor for detecting an out-of-syrup condition.

Abstract: A vacuum sealing device includes a plug (58) which is thrust into a port (4) of an insulated steam injection tubing (1) for closing an annular space of the tubing which confines a vacuum. The plug (58) is mounted for movement within a first mounting element (30) and for movement within a bellows (32) having an end connected to the first mounting element (30). A second mounting element (34) is connected to the opposite end of the bellows (32) and carries a rod (40) which is fixed to the plug (58). By relatively moving the two mounting elements (30, 34) together, the bellows (32) is compressed and the plug (58) is thrust by movement of the rod (40). The first mounting element (30) is connected to an upper clamping section (12) which co-operates with a lower clamping section (14) to engage around a tubular member (3) to be plugged. The upper section (12) can be correctly centred with its plug (58) over the port (4) of the tubular member (3) by momentarily compressing the bellows (32) to extend the plug (58). The plug (58) is provided with a shank portion and a breakable tab for breaking the plug away from the shank portion. The shank portion is connected to the rod (40) so that after the plug (58) is seated in the port (4) the rod (40), its mounting elements and the clamp section (12, 14) can be removed from the insulated steam injection tubing (1).

Abstract: The invention relates to preventing oil damage in open water. The invention is based on the fact that the viscosity of oil changes as a function of temperature. Fig. 1 shows the operating principle. The catamaran-type vessel is provided with two cylinders (2) which are kept at a lower temperature than the water, using cooling units (5). The oil (7) floating in the water comes into contact with the cylinder (2), congeals and adheres to the surface of the cylinder. As the cylinder rotates, the oil is transported on the surface of the cylinder until it reaches a heated collection gutter (8) where it is collected. From the gutter it is directed into a collecting tank which is located in the vessel. The dimensions of the vessels, of the cylinders, and of the cooling unit can be chosen freely according to the conditions.

Abstract: A press fabric, for use on papermaking and similar machines, is of the open-ended variety, and has loops at each end enabling it to be closed into endless form during installation on the machine by means of a pin seam. The machine-direction (MD) yarns 1, from which the loops are formed during the flat or endless weaving of the fabric, are coated multifilaments. The coating 3, either permanent, semi-permanent, or soluble, gives the multifilament 2 a monofilament-like structure, enabling good loop formation and stability. The use of multifilament yarn provides a fabric having improved elasticity in the machine direction, and a greater degree of compressibility, following the removal of a soluble coating material, than can be obtained using monofilament yarn.

Abstract: A low power control apparatus for a coin operated telephone controls a full range of phonefunctions as well as an electronic coin acceptor. The control utilizes phone line power. Power for all the normal operations of the coin operated telephone and its coin acceptor (30) is also supplied from the phone line. The control is preferably microcontroller based and designed utilizing low power components. In the control, an interface circuit (55) serves to connect the phone tip and ring lines to either a power supply circuit (230) or to a totalizer (350) and escrow control circuit. The power supply also provides power to an audio network (380) including a variety of fraud prevention circuits, a modem (400), and several time generator circuits. A monitor system (510) monitors the status of several security switches to monitor the phone's condition. Hardware and software design features control the application of power to circuits only when needed.

Abstract: A plastic venting closure (20) comprising a base wall (21), a peripheral skirt (22) having internal threads (23) adapted to engage the threads (24) of a container and wherein the threads are interrupted at circumferentially spaced points to define axial venting passages (25) for dissipating pressure of the contents as the closure is unthreaded from a container. At least some of the passages have an integral rib (26) thereon spaced from the threads and extending axially. The radial thickness of each rib is less than that of the threads and preferably is arcuate in a radial direction and arcuate in a axial direction and preferably has an axial length greater than a transverse width such that it may span and engage several threads at the same time. The closure can be used with a glass container having a continuous thread and a plastic container having continuous thread or an interrupted thread. By having each rib (26) arcuate in an axial direction it may engage a plurality of threads (24) at different radial points on the rib thereby minimizing application and removal torque while centering the container relative to the closure. <IMAGE>
