Abstract: A lubrication pump includes a housing defining a bore, an adjustable cylinder sleeve within the bore, and a piston slidably movable within the bore along a longitudinal axis of the bore. A connector may be drivingly interposed between a cam and the piston for driving the piston in reciprocating axial motion. The connector may have a coupling for engaging the piston, which may enable rotational engagement between the connector and the piston. The connector may have a roller for bearing engagement with the cam, which may enable the connector to rotate about the longitudinal axis relative to the housing as the connector moves axially within the bore. The cam may be laterally displaceable relative to the connector. The cylinder sleeve may be adjustable relative to the piston for varying lubricant fluid output flow. The cylinder sleeve and corresponding piston may be interchangeably disposed in the housing.

Abstract: A touchless vend system includes a first processor and a second processor, each within a vending machine and communicably coupled to one another. The first processor can receive a signal representing a product selection, associated with a product in the vending machine, from a mobile device. The first processor can transmit a payment authorization to a controller of the vending machine, and transmit the signal representing the product selection to the second processor. The second processor receives the signal representing the product selection from the first processor, converts the signal representing the product selection into an electronic signal based on a make, a model, and version information of the vend machine, and sends the electronic signal to the controller to cause vending of the product.

Abstract: Tactical routing apparatus e.g. for an aircraft comprises stores for storing data representing the geographical domain through which the aircraft is to pass and data representing the location and type of a plurality of threats (e.g. gun or missile sites), and a processor for determining and displaying on a V.D.U. the optimal route connecting two points and the probability of successfully completing the route.

Abstract: A data processing arrangement is operative to combine data representing different kinds of information from disparate sources. The data is stored under assigned addresses having a mutually compatible co-ordinate format, and is processed using those addresses. Relevant portions of data from a very large amount of information can be readily extracted in this way, and combined with other data which is related by virtue of a common address. The arrangement is applicable to flight management of an aircraft.

Abstract: A resource allocation system for indicating the optimum allocation of a resource between a series of demands iteratively processes the probability data for each demand to determine for each of a range of amounts of resource available the optimum distribution of the resource between the demands and the resultant probability of successfully overcoming all the demands. The system may be used to predict the probability of success where there is a limited resource available and a predicted series of demands, but it may also be used to assess non-predicted threats and to determine an updated optimum distribution and resultant probability.

Abstract: A cyclical lubricant feeder utilizing series spool valves to dispense measured quantities of lubricant to dispensing outlets from a common feed source with a plurality of the spool valves arranged in series in valve block assemblies which in turn are in series with one another whereby dispensing through the outlet for each spool valve in a block assembly is in progression with the other outlets from the spool valves in the valve block assembly is provided with a control valve controlling inlet and outlet flow to the valve block assembly bypassing flow from the inlet to the outlet when all of the valves in the block have been shifted to one side and bypassing flow from the outlet to the inlet upon reverse lubricant flow to the block only when all of the valves in the block have been shifted to the other side.

Abstract: A lubrication device employing a reciprocable plunger, as the actuating member, which is driven by a rotatable cam member through a pivoted rocker arm engaged with the plunger and having roller means engaging the cam, with the axis of the plunger, respective pivotal axes of the cam, arm and roller means, and line contacts between the roller and cam and between plunger and arm being so related that actuating forces are transmitted from the cam to the plunger substantially on the axis of the plunger, substantially eliminating undesirable lateral forces on component parts and enabling the use of simple bearing structures for the cam shaft. Operation is further improved by a novel disposition of valve means in the lubricant supply line.
