Patent EP-0331473-A2 (EP)
Inventor: SHARMAN RICHARD IAN
IPC: A01K5/02
Filed: 1989-03-01
Abstract: A poultry feed conveyor of the drag chain type, for bringing feed to the birds in an intensive poultry house comprising a chain constructed from moulded plastics links 22. Each link is cruciform, comprising a body 26 and a cross-piece 28. Coupling formations 32 and 34 of the body enable the links to be interconnected by pivot pins 24. The cross-pieces present feed-engaging side faces 70 and 72 which are raked back from lowermost edges of the cross-piece to give a scraping action in sliding along the bottom 14 of a feed trough 10. The bodies 26 and cross-pieces 28 of the chain have sufficient height for the chain to form a grid which compartmentalises the trough to inhibit flicking and consequent wastage of the feed by the birds.

Abstract: This variable-current source comprises a differential stage (10) and a pair of voltage buffers (11,12) which respectively receive, at the input, a variable input voltage (V IN ) and a reference voltage (V REF ) and are connected at the output to the differential stage. Both buffers comprise a resistor (R₁,R₂) flown by a current which varies only as a function of the respective input voltage and of its resistance and therefore depends thermally exclusively on this resistance, and provide output voltages (V₁,V₂) which depend upon these currents, so that the output current generated by the differential stage (10) is temperature-­independent.

Abstract: A method for fabricating a split-gate EPROM cell utilizing stacked etch techniques is provided. In accordance with a preferred embodiment of the method, a layer of silicon dioxide is formed on a P- silicon substrate. A layer of polysilicon is then formed on the silicon dioxide layer, followed by the growth of a oxide/nitride/oxide (ONO) layer. The ONO and polysilicon layers are then etched to define floating gates. Next, an edge of each floating gate is utilized in a self-aligned implant of buried N+ bit lines. The floating gate extends only over a first portion of the channel defined between the adjacent buried bit lines. A differential oxide layer is then grown on the substrate between adjacent floating gates in a low temperature steam oxidation step. That is, the oxide formed over the exposed portion of the buried N+ bit line is thicker than the oxide formed over the exposed portion of the channel. Following formation of the differential oxide layer, a second layer of polysilicon is formed and then etched to define control lines that extend perpendicular to the floating gates in the conventional split-gate EPROM cell structure. The control gates are then utilized in a stacked etch to complete the split-gate cells. The etch is carried out such that the oxide overlying the N+ bit lines protect the surface of the substrate, avoiding bit line interruption, while the silicon dioxide overlying the exposed portion of the channel is overetched to form a trench into the channel that extends below the junction depth of the N+ region, thereby eliminating bit line to bit line reach-through.

Abstract: An apparatus and method which provide job integrity and security for each sheet transported to and from a printing station (84) of a printing machine, including periods when the printing machine has cycled down enabling an operator to remove sheets therefrom. Each sheet transported to the printing station and each sheet delivered from the printing station is counted (92, 93). A controller (5) compares the number of sheets transported to the printing station to the number of sheets delivered from the printing station and the number of any sheets that may have been removed by the operator from the printing machine as a result of a cycle down. Operation of the printing machine will be inhibited if the number of sheets transported to the printing station do not equal the number of sheets delivered from the printing station and the number of sheets removed by the operator. Conversely, operation of the printing machine will be enabled if the number of sheets transported to the printing station does equal the number of sheets delivered from the printing station and the number of sheets removed by the operator.

Abstract: A method is disclosed for automatically transmitting a message to the originator of an electronic document from an intended recipient upon a failure of the system to successfully deliver that document. In one embodiment of the present invention, a user is prompted to enter a selected message in response to any action which disables the delivery of an electronic document. Thereafter any attempted delivery of an electronic document will result in an automatic transmittal of the selected message to the originator of the electronic document. Additionally, the user may specify that the selected message is to be transmitted to a selected group of document originators and no others; that the selected message is to be transmitted only in response to a particular type of delivery failure; or, that the selected message is only valid during a selected time frame. In this manner an intended recipient may selectively notify the originator of an electronic document of the reasons for a failure of delivery and the likely duration of such failure. In data processing systems in which a recipient may specify the automatic deletion from his or her in-basket of an electronic document upon the elapsing of a specified delivery time or other specified reasons, the recipient may also elect to have a message automatically transmitted to one or more originators of deleted documents.
