Title: Aminoureaformaldehyde fertilizer method and composition
Inventor: MOORE WILLIAM P
IPC: C05C9/02
Filed: 1993-12-30
Abstract: A new method of preparing a new aminoureaformaldehyde fertilizer composition which exhibits high cold water insoluble nitrogen (CWIN)levels and high Availability Indices (AI). The method utilizes the discoveries that ammonia compounds, usually ammonium salts, inhibit the urea-formaldehyde polymerization reaction and decrease the formation of hot water insoluble nitrogen (HWIN), and that the ammonium compounds take part in the reaction to form controlled release compounds which are both cold water soluble and insoluble. The process is carried out at elevated temperatures between 60 and 125 °F, so mat it may be completed in an older of magnitude less time than either the dilute or concentrated conventional commercial ureaform processes, requiring between 2 and 20 minutes for completion. In the process, between 3 and 25 per cent of the total nitrogen is supplied as ammonia nitrogen with the remainder from urea, respective formaldehyde to urea to ammonia mol ratio is 1.0, between 1.0 and 2.0 and between 0.05 and 1Ø The new fertilizer composition is produced directly as semi-dry granules, and exhibits urea conversions to CWIN  between 50 and 85 per cent with AIs higher drop 45.

Abstract: A device for separating the yolk and albumen of an egg is provided.  A housing includes an inner chamber and an outer chamber. A lid member is detachably coupled to an upper edge of the housing.  The lid includes an annular member positioned above the inner chamber and a plurality of slots disposed adjacent to the annular member communicating with the outer chamber. The annular member is sized for retaining the yolk and for causing the albumen to overflow the annular member  with the slots allowing the albumen to flow downwardly into the outer chamber. A lever is pivotally coupled to the annular member. The lever has a bottom portion abutting a bottom edge of the annular member for enabling dispensing of whole yolk retained in the annular member into the inner chamber without breaking the yolk. A funnel is detachably mounted on the lid. The funnel has a bottom opening positioned above the annular member for directing the egg to the annular member.  A circumferential flange on a top edge of the funnel provides an anvil for breaking the shell of the egg prior to dispensing the egg in the funnel member.  The housing may optionally be provided with a closeable spout communicating with the outer chamber.  The spout provides facile removal of albumen retained in the outer chamber.

Inventor: ST DENIS LUCIEN
IPC: B21D39/02
Filed: 1995-09-07
Abstract: A hemming machine for simultaneously bending a flange on a first panel into engagement with an edge portion of a second panel to form a hem, and at least partially curing an adhesive located in the hem.  The flange bending members and/or the top surface of the panel support nest of the present invention are heated using electric cartridge heaters, hot oil, or electric heating cables, for example.  During the hemming operation the nested panels are in constant direct contact with the panel support nest, and the heated flange bending members are in direct contact with the hem for approximately 3 to 6 seconds (dwell time is dependent on whether the die blocks are heated or if the die blocks are heating in conjunction with the top surface of the panel support nest), which is generally sufficient to at least partially cure the adhesive located in the hem, thereby reducing the incidence of panel shift during subsequent transfer through the manufacturing process using conveyors, racks etc.  By combining the hemming and heating/curing operation of adhesive bonded hems into a single machine and operation, significant savings in machines and assembly time are realized.

Inventor: AGARWAL ANANT
IPC: G01R31/00
Filed: 1994-04-01
Abstract: A compilation technique overcomes device pin limitations using virtual wires. Virtual wires overcome pin limitations by intelligently multiplexing each physical wire among multiple logical wires and pipelining these connections at the maximum clocking frequency. Virtual wires increase usable bandwidth and relax the absolute limits imposed on gate utilization in logic emulation systems employing Field Programmable Gate Arrays (EPGAs). A "softwire" compiler utilizes static routing and relies on minimal hardware support. The technique can be applied to any topology and FPGA device.

Abstract: A guard rail support is removably installable along a roof edge and provides for the safety of workers on a roofing project.  The guard  rail  support  is  adjustable  to provide  a  substantially vertical fence plane, depending upon the slope of the roof to which the support is installed.   The adjustment is dependent upon the pitch of the roof, and provides adjustability for most commonly encountered roof pitches.  The support basically comprises three major components:   A fixed length base plate, a single upright member with pitch slope adjustment holes therein,  and a fixed length diagonal member extending between the base and the upright.          The base member is temporarily secured to the roof (e. g., nailed), and the upright attachment end of the diagonal is installed in the appropriate  hole  in  the  upright  member  to  keep  the  upright substantially vertical for the pitch of the roof to which the device is installed.  A plurality of guard rails is then installed in tubes attached to the upright.  The supports are easily removed when the roofing job is completed, without damage to either the supports or the rails, and may be folded for compact storage and later reuse.   Both the support components and the rails are of readily available construction materials, for ease of fabrication and use.

Title: Valve for inflatable packer system
Inventor: BROOKS ROBERT T
IPC: E21B33/124
Filed: 1996-01-25
Abstract: A pressure limit valve for well tools where a valve member is moveable between a first closed portion, an open position and a second closed position. A spring for closing the valve is separated from a locking chamber which contains locking elements.      The locking elements are located in a locking chamber and are held deactivated by a release sleeve which separates from the valve member in an open position.

Title: Manufacture of knitted brief blanks
Inventor: VAN LAAR ANTONIE HENDRICK
IPC: D04B1/24
Filed: 1994-09-07
Abstract: A method of knitting side-by-side brief blanks (BLK,BLK') in the form of a tube (T) on an electronically controlled circular knitting machine wherein the tube (T) is shaped by needle selection (50) between the brief blanks (BLK,BLK') to form apertures (AP, AP') which provide leg openings (LO,LO') by taking out of action needles (50') which would otherwise knit yarn across the apertures (AP, AP'). At the same time yarn feed (Y2) to the inoperative needles (50') is cut (42, 44) and trapped (46) whereby the apertures (AP, AP') are formed. End portions of the blanks (BLK,BLK') remain interconnected until the tube (T) is slit walewise to provide separate blanks (BLK,BLK') for making up briefs. Since yarn is not knitted across the apertures (AP, AP'), a considerable saving in the use of yarn is effected whilst shaping of leg openings (LO,LO') is facilitated.
