Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed herein is a device for dosing granular products, particularly foodstuffs such as cereals, rice, pasta and the like.        The technical problem that has to be solved is how to design a dosing device capable of offering maximum hygiene guarantee and having the ability to apportion the product in a way that is extremely precise, yet easy to set or modify according to the requirements.      The solution to the problem is achieved through a dosing device that comprises a delivery pipe in which are drilled holes of a size less than that of the granular product to be supplied, suction means connected to the delivery pipe through an annular channel that partially enshrouds the said pipe, and means which, when set in operation, interrupt the flow of air from the delivery pipe towards the suction means.

Abstract: ABSTRACT    In a  dead reckoning navigation system a correlation scheme that operates in the frequency domain (using a discrete cosine transform (DCT) function) is implemented separately from the navigation system to determine a two-dimensional position error estimate. In this separate processing system measured terrain data is correlated (in the frequency domain) with reference elevation stored in map format (as by way of a digital map generator (DMG)).  The results of this correlation are then employed to enhance the independently operated dead reckoning navigation system so that an accurate determination of geographic position may be obtained.

Abstract: INPUT BUFFER CIRCUIT FOR RECEIVING MULTIPLE           LEVEL INPUT VOLTAGES                           Abstract An input buffer circuit (10) having a single input for receiving input voltages (VIN) characterized by having varying voltage swings is provided.  First (12 and 15) and second (16 and 18) inverter circuits having differing switchpoint voltages are coupled to a level shifting portion (13, 17).  The level shifting portion varies the level of swing of the input voltage (VIN) and buffers the input voltage (VIN).  In one form, voltage coupling circuitry (22, 23) is interposed between the level shifting portion and a latching portion (25, 26) which provides the input voltage (VIN) as an output signal at a predetermined voltage level. In another form, voltage coupling circuitry (48, 53) controlled by control circuitry (49, 50, 57) couples the output of the level shifting portion (43, 44) to an output in response to the input voltage (VIN).

One of the toothings on the double gear is an oblique toothing, and the other toothing on the double gear has a direction differing from the above-mentioned oblique toothing.  Both toothings on the double gear are immovable relative to each other.  The double gear is mounted on bearings so as to be axially immovable and is connected with a first adjustment device, and the plate cylinder is mounted on bearings so as to be axially immovable and is connected with a second adjustment device characterized in that the second toothing (12;114) of different direction on the double gear (10;110) is a straight toothing.

Abstract: ABSTRACT        An automatic coffee pot which can be used interchangeably to make espresso, "American" coffee, or cappuccino within the same unit, uses a disk-shaped clamp having a plurality of filter openings therethrough seated on the coffee grounds in the interior of the filter basket to prevent the coffee from being driven by steam and boiled water generated in the pot upwardly and outwardly towards the outer diameter of the basket thereby subjecting all of the coffee beans to the steam and boiled water passing therethrough so that the beans are fully cooked or brewed and not wasted, enabling less coffee to be brewed with a given volume of water so that weaker "American" coffee can be made in the pot.  A telescoping tube with a handle is provided which is disposed over a hollow longitudinal tube in an upper chamber of the pot after cream is poured into the upper chamber before or as the coffee is brewed therein and passed through the inner tube.  The outer telescoping tube is provided with a vent in its side wall beneath the level of cream disposed in the upper chamber so that steam and hot water generated in the inner tube and exiting via the orifice in the side wall thereof is directed back to the bottom of the outer telescoping tube and vented through its side wall vent immersed in the liquid cream to heat and froth the same and mix the cream with the brewed coffee exiting from the inner tube to form cappuccino.

Abstract: PROPORTIONAL HYDRAULIC SOLENOID CONTROL            ABSTRACT:     A control valve assembly (10) is disclosed for control of a fluid pressure between a variable fluid pressure source (59) and a fluid operable device (60).       This assembly provides a valve means to open or close flow from the fluid pressure source (59) in response to a change in a significantly lower fluid pressure in a pilot chamber, which fluid pressure is controlled by a proportional solenoid operator (52) requiring small current flow.  This small current flow to the solenoid operator (52) is due to the low pressure in the pilot chamber, which when relieved or increased effects a change in the valve means to open or close fluid flow to or from the fluid pressure source (59).

Abstract: LINEAR OPERATING MECHANISM FOR ELECTRICAL SWITCHES                  ABSTRACT OF THE DISCLOSURE   A linear operating mechanism is provided for operating one or more electrical switches or interrupters, the mechanism selectively closing the switch via movement of a switch operating member and immediately thereafter being capable of opening the switch as required. The operating mechanism includes a carriage that is movable over a linear path to charge an opening spring and a closing spring. The switch operating member is movable along an axis parallel to or coincident with the path of the carriage. The opening spring and the closing spring are disposed about a common axis parallel to the movement of the carriage and the switch operating member. A first latch arrangement is provided for preventing switch-closing move-ment of the switch operating member when the switch is open and the first latch arrangement is engaged. A second latch arrangement is provided for preventing movement of the carriage opposite to the direction of charging movement after the springs are charged and when the second latch arrangement is engaged. The latch arrangements each include a gapped, latch ring that cooperates with a latch member that is received within the gap of the latch ring. The carriage and the switch operating member each carry one of the latch rings. The latch members are slidable and pivotal with respect to the plane of the latch rings to accomplish latching and trip release movement. When it is desired to close the switch, the switch operating member is released and the closing spring drives the switch operating member to close the switch. Thereafter, when it is desired to open the switch, the carriage is released and is driven by the opening spring to move the switch operating member to open the switch. Orientation control arrangements are provided to control the orientation of the carriage and the switch operating member with respect to the latch member and to control orientation of each latch ring with respect to the carriage or the switch operating member which carries the respective latch ring.

Abstract: CONTAINER CLOSURE                 Abstract of the Disclosure A container closure adapted to  be  applied to  a container having threads by an axial movement and to be removed by a rotary movement to open the container comprising a body including a base wall and a peripheral wall and a gasket of plastic material formed in situ along the peripheral wall and at least a portion of the base wall which is adapted to overlie the end of the container.  The surface of an annular portion of the gasket along the peripheral wall is formed with a plurality of circumferentially extending substantially flat surfaces such that it has a polygonal configuration in transverse cross section with axially extending channels at the junctures of the sub-stantially flat surfaces.  When the closure is applied to the container, the threads on the container deform the surfaces of the polygonal portion by indentation to define complementary threads therein. When the closure is being applied, the channels permit gases in the head space of the container to escape so that excessive pressurization tending to force the cap off does not occur.  After the closure is applied to the container, the channels provide areas into which the plastic material may cold flow to release excessive compressive stresses which develop during shelf life of the package comprising the closure and container, thereby resulting in lower removal torques.
