Patent MX-9703312-A (MX)
Title: Lubricant additive formulation.
Inventor: BAUMGART RICHARD J
IPC: C10M105/32
Filed: 1995-11-03
Abstract: A lubricant additive formulation for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. The engine treatment oil additive comprises a synergistic blend of an oil soluble molybdenum additive, polyalphaolefin, ester such as a polyolester or diester, polytetrafluoroethylene, dispersant inhibitor containing zinc dithiophosphate, mineral oil base stock, viscosity index improvers, and borate ester used in combination with a conventional crankcase lubricant at about a 20 to about a 25 percent volume/percent. The improved performance of the engine additive in comparison with conventional crankcase lubricants is attributable to the effect of optimizing the design parameters for each of the individual chemical constituents and combining the chemical constituents according to the present invention to obtain surprisingly good results including improved: wear, oxidation resistance, viscosity stability, engine cleanliness, fuel economy, cold starting, and inhibition of acid formation.

Inventor: STOCKLEY HENRY WALKER III
IPC: B65B7/16
Filed: 1996-06-06
Abstract: A package and a method for making a package which allows for the central processing of fresh red meat is disclosed which includes a tray (12), a first film (24) enclosing the product (20) within the tray and a second film (30), which is removed at retail, enclosing the first film. The first film and the second film are sealed to the inner periphery (27) and the outer periphery (31), respectively, of the single flange (22) of a conventional foamed or nonfoamed tray. The first film is a heat shrinkable film which is sealed to the inner periphery of the flange forming a first seal (26), trimmed outboard of the first seal, thereby forming an excess portion (28) of the first film outboard of the first seal, and then subjected to a sufficiently high temperature to shrink the excess portion and thereby expose a sealing area (29) on the outer periphery of the flange. The second film is then sealed to the sealing area on the outer periphery of the flange, forming a second seal (32) such that the second film encloses the first film.

Patent NL-6815097-A (NL)
Title: Production of syrup wafers
IPC: A21B5/02
Filed: 1968-10-23
Abstract: Syrup wafers with syrup between the upper and lower parts of the wafer are produced by injecting the syrup between the non-separated wafer halves during or immediately after the baking of the wafers, and then, when necessary, closing the opening through which the syrup is injected by further baking. The method enables syrup wafers to be continuously and automatically produced with a minimum use of manual operations. The waste material produced when the wafers are formed by stamping is avoided. A thin syrup can be used, instead of the thick syrup formerly used, which tended to provide tough syrup wafers.

Patent NL-7415901-A (NL)
IPC: F23C6/04
Filed: 1974-12-06
Abstract: A flame is produced in a combustion chamber with a burner supplied with fuel and less than the amount of air for complete combustion. The remainder of the air required for complete combustion is injected separately. Stack gas containing substantial carbon dioxide is mixed selectively with the gaseous combustion products. By well known reactions the carbon dioxide reacts with carbon in the combustion products to produce carbon monoxide which is later oxidized to carbon dioxide under conditions which do not promote production of noxious nitrogen oxides. The principles of the invention are applicable to a variety of fuel burners.
Patent NL-7612508-A (NL)
Title: Gas heating operating system - uses heat exchanger cooling combustion gases below dew point and has reheating layout
IPC: F24H8/00
Filed: 1976-11-10
Abstract: The system operates a gas-fired heating system, a fluid being heated by the combustion gases in a heat exchanger and then delivered to the rooms served, returning to the heat exchanger after cooling. The heat exchanger is so dimensioned that the gases are cooled to below dew point. The condensate is led away and the gases are reheated, mixed with air as necessary, and mechanically discharged via insulated pipes. The gases can be reheated to 50 deg. C max., or the air to be added to them can be heated by the convection losses from the equipment before mixing. As a further alternative, heating can take place after mixing, and the reheating energy can amount to a maximum of 2% of full load.

Title: Liq. metal coolant pump of nuclear reactor - maintains coolant level above impeller using axial bores and upstream second impeller
IPC: F04D7/06
Filed: 1982-07-16
Abstract: The pump comprises a housing (1,2) with the drive motor (4) arranged at the top (cover 6) and connected with a long vertical pump shaft (3) whose lower end carries a bladed (18) centrifugal pump impeller (14) rotating in a guide member (11) at the lower end of the housing (1). The housing (2) has a central axial inlet opening (12) below the impeller connecting with an inlet line (13) and a radial outlet line (20) at the level of the impeller (14). To maintain a predetermined coolant level (22) in the housing (1,2) above the impeller (14), a bladed (19) induction impeller (15) is secured below the impeller (14) whilst the latter is provided with a number of axial bores (21) which connect the space between the impellers (14,15) to the inside of the housing (1,2). The arrangement permits installing the pump in the cold leg of the circuit without the need for overflow lines from the housing space above the impeller (14) to the pump inlet (to prevent excessive rise of level 22), and prevents the risk of this level dropping too low which would introduce gas from the gas-pressurised (23) space above the level (22) into the outlet (20) and endanger the reactor core.
Patent NL-8203647-A (NL)
IPC: E04F17/02
Filed: 1982-09-21
Abstract: In a method of making a fibrous thermally insulating layer of coherent structure, a quantity of fibers is treated with a binder, whereby prior to or during the treatment with the binder, fibers are formed into a quantity of particles each having a substantially rounded periphery and consisting of a number of short fibers and the particles treated with the binder are conveyed by means of a gas as conveying medium via an inlet piece 11, 13 to within a container 3, the particles being blocked by an outlet piece 8 for the container, the outlet piece 8 being formed with gas outlet apertures 10. The particles are formed by vigorously agitating a number of flakes in a vessel, each flake consisting of arbitrarily arranged short fibers, and simultaneously applying pulsating forces to at least part of the volume of flakes, so that the flakes are converted into particles having a substantially rounded periphery and having a higher density than that of the flakes.
