Abstract: A unique financial process to create a banking product which would replace transactions made by: 1. money  2. cheques  3. certified cheques  4.  money orders  5. visa*  6. visa cheques  7.  line of credit cheques  8. bank drafts  9. travellers cheques  10. client cards used for banking machines.    The proposed financial product called, "XYZ (company name) Guarantee Money" will have the appearance of money and not a cheque or money order and it will state in bold letters that the maximum that shows on the bill is guaranteed by the Bank or Trust company or Credit Union or other qualified institution which issued the bill.          The proposed financial product will be created by a bank or other qualified financial institution in a similar fashion as a money order, or certified cheque, or a travellers cheque, or bank draft is created when a customer of a bank pays money for the money order or certified cheque or travellers cheque or bank draft.  In this invention the customer will pay to a Bank the maximum that will show on the Guaranteed Money issued.  The guarantee money bill though will be different than the four products mentioned in this paragraph as it will have the space for how much it will be used for, blank, and it will only be filled out at the time of purchase, with the exact amount.  The owner of the Guarantee Money will be able to purchase products or services to the maximum that will show on the bill.          For example, for a Guarantee Money issued by the Bank for $20.00 dollars maximum, the owner of the bill will purchase a product for say $16.00 dollars and print the words sixteen dollars and the number $16.00, then insert the name of the vendor on the bill and sign it just like in the case of a cheque.  When the vendor deposits the bill in his Bank he will be credited only $16.00 dollars and the purchaser will be credited the remaining $4.00 dollars. If a purchase of $20.00 dollars is made then the vendor will be credited for $20.00 dollars and the purchaser zero since all the money is spent. By using Guarantee Money people will not have to look for change in their pockets and they will not have to wait for change.

Patent CA-2127948-A1 (CA)
Inventor: DEGANI YINON
IPC: H01L21/60
Filed: 1994-07-12
Abstract: Described are a process for soldering at least one component having solder bumps to a substrate and a process for forming solder bumps on metal pads of an element, such as an IC package or substrate or both. The bumps are formed by stencil printing solder paste deposits on the metal pads, heating the solder paste deposits to reflow temperature of the solder in the solder paste deposits, and allowing the molten solder in each deposit to coalesce and during subsequent cooling solidify forming the bumps on the metal pads. The bumps are formed by conducting the stencil printing through apertures in an ultra-thick stencil, the apertures having trapezoidal crossection in the plane normal to the broad surfaces of the stencil with the top opening being smaller than the bottom opening and with the walls of the aperture sloping at an angle within a range of from 1 to 45 degrees from the vertical, the solder paste having a low tackiness and high metal loading, and the solder paste deposits covering an area which is equal to or exceeds an area of the metal pad in any ratio between 1.5:1 and 5:1. Bumps formed in this manner lead to the formation of reliable solder joints.

Title: System and method for collecting cutting fluid liquid and chips
Inventor: BRATTEN JACK R
IPC: B01D37/00
Filed: 1995-06-20
Abstract: A system and method are disclosed for collecting cutting fluid and chips from a number of machine tools includes a series  of  sumps  each  collecting  chips  and  fluid  at  a particular machine tool, and a central sealed collection tank drawing from all of the sumps by drawpipes inserted in each sump.   A single large capacity pump pumps to filtration equipment, with a predetermined vacuum level maintained in the tank by opening and closing an outlet valve between the pump and the filtration equipment.  A level switch at each sump causes intermittent opening of an associated valve causing each sump to be placed in communication with the vacuum in the collection tank,  and random opening of the valves causes individual sumps to be emptied by the full suction at the collection tank.  The drawpipes are equipped with antivortex end shapes to allow rapid evacuation without drawing air into the system.  A vacuum pump removes excess air accumulating in the collection tank.
