Disclosed herein are compositions which are highly effective rodenticides. The compositions include a plurality of glass whiskers which rodents are naturally attracted to for purposes of nest building, or are otherwise induced to pick up in their mouths. Upon biting the whiskers for either transport or eating, the rodents oral mucosa becomes irritated, often to the extent that the rodents are unable to subsequently eat without excruciating pain. Hence, the rodents death by starvation is inevitab...

Interactive data processing unit which is located at a distance from an FA control unit and capable of direct access to a memory in the FA control unit. When an access request to a memory (3) in a CNC (30) is issued by a device in an MMC (20), a remote access control means (1) outputs the access request to the CNC (30). Upon reception of the access request, an internal data input/output means (2) in the CNC (30) makes access to the requested address by performing a direct memory access (DMA) ope...

A hybrid control system executes tasks within a transaction which is executed in a given order. The order in which the tasks are executed is inversely proportional to their deadlines. The deadlines are assigned an initial deadline D, an initial maximum end-to-end delay of the transaction is calculated using the initial deadlines D and the given order of the tasks. The deadline of the task with the largest deadline is reduced by an increment to give a new deadline and if the task following it has...

A pneumatic control apparatus and method controls gas pressure inside a tire (40) mounted on a wheel (32) which rotates about the centerline of an axle (30). A bleeder valve (28) is mounted on a body coaxially aligned with the axle centerline and is in fluid connection through passages (14, 18) in the billet and tubing (24) with a pneumatic fitting (23) on the tire. The bleeder valve allows gas inside the tire to be relieved to the atmosphere when the gas is above a set pressure. The coaxial ali...

A control console comprising at least one member (1) for adjusting the level of radio-electric signals capable of taking up any position between two extreme positions, elements for detecting the instantaneous position of the member and elements for memorizing at least one position of the member. This console is characterized in that each adjusting member is provided with both motor mechanism for automatically positioning the adjusting member in its memorized position corresponding to a status of...

The present invention discloses a controller unit wherein coils of the electromagnets of a hydraulic brake system are arranged in a frame. The controller unit also has a printed circuit board having smaller dimensions than the frame. The printed circuit board includes through-contact holes which accept the ends of the lead wires for the coils, the ends being configured as press-in pins. The plug contacts of the printed circuit board are arranged so as to achieve an optimum component layout on th...

A control valve which is useful for controlling devices without the use of direct electrical power. The control valve is configured such that it allows for the control of flowable media, such as water, hydraulic fluids, and it can also be used with gases, including air, and the like.

An engine control for an internal combustion engine is disclosed. The engine preferably includes at least two cylinders or combustion chambers. The engine control is arranged to run the engine in a first mode in which all cylinders are operating and a second mode in which at least one of the cylinders is disabled, such as by misfiring the ignition element corresponding thereto. The engine control is arranged to operate the engine in the second mode only when a predetermined condition, such as id...

A mobile machine which carries the operator of the machine is equipped with a control which has a shape, geometry and motion analogous to that of the machine and which causes machine motion analogous to the motion imparted to the control by the operator. The analog control may be applied on mobile equipment including aerial work platforms, forklifts, front end loaders, backhoes, earth movers, bulldozers, diggers, trenchers, agricultural equipment, mining machinery, and other operator controlled ...

A fan control system for a vehicle cooling system includes forward and reverse relays connected to a microprocessor based timer control. A third relay is controlled by a single temperature responsive switch or thermostat and selects either the high speed or low speed winding of an electric radiator fan or similar engine cooling device dependent on the temperature sensed by the thermostat. The thermostat also provides an input to the timer control to adjust or interrupt preselected timing functio...
