Title: Electronic engine control module incorporating glow plug and glow plug lamp control
Inventor: GRASSI ROBERT P
IPC: F02P19/02
Filed: 1992-10-14
Granted: 2003-04-29
Abstract: The engine control module incorporates strategy which controls and modulates glow plug activation and also controls activation of a glow plug indicator lamp mounted in the cab of the vehicle.

Title: Hood for fireplace
Inventor: RIEGER HEINZ H
IPC: F24B1/18
Filed: 1992-11-12
Granted: 1999-04-13
Abstract: A fireplace has a manifold positioned between a combustion chamber and a flue.  The manifold has a pair of inlets to supply dilution air to the flue, one extending from a front face of the fireplace, and the other from a rearward location.  A baffle extends across the outlet of the manifold to prevent direct communication between the combustion chamber and flue. The inlet at the front face enables the flow of dilution air to be checked with the fireplace installed without having to accomodate the full flow of dilution air.  The baffle prevents downdrafts from adversely affecting the combustion in the combustion chamber.

Abstract: A butter-like food fat being directly spreadable at refrigeration temperature, i.e. 4 to 5 °C, and preferably containing 80 to 83 % fat is produced by addition of vegetable oil, water, and salt. Initially conventional butter is produced, which preferably con-tains 80 to 83 % fat and which is made exclusively from milk. Subsequently, the conventional butter is passed continuously through a tight, closed plant, whereby the butter initially passes through a kneading station followed by addition of half the total amount of added vegetable oil. Then the butter mixture passes through a mixer, whereafter the remaining portion of the amount of added vegetable oil and water and salt are added. In this manner buttermilk results exclusively as a by-product from the pro-duction of the conventional butter and contains thererefore nothing but pure milk fat. Accordingly, the buttermilk can be used ~ market milk and sold at the highest possible market price. In addition, a particularly high production flexibility is obtained dur-ing the production of butter.

Title: Ring binder cover
Inventor: PODOSEK EDWARD
IPC: B42C7/00
Filed: 1993-04-21
Granted: 2000-04-04
Abstract: A ring binder cover (4) is composed of a pair of thermoplastic sheets (20, 22) superimposed in edge-to-edge relation with a stiffener insert panel (23) disposed therebetween. The insert panel bears two parallel grooves (25, 27) which divide the insert into a spine zone (30) and two cover zones (24, 26). The material of the insert lying at the bottom of the grooves forms a pair of webs (32, 34) which, combined with the adjacent portions of the cover sheets, form hinges between the spine and each cover. The peripheral. edge portions (40) of the two thermoplastic sheets are sealed together and provide a sealed envelope for the stiffener insert which defines semi-rigid back and front cover panels of the binder, hingedly connected to a rigid spine.  The insert can be provided with insert notches (370, 470, 570) at each end of each web to reduce outward protuberance of the peripheral edge at the hinge ends. At the mouth of each insert notch, the peripheral edge can carry straight, across, or can follow inward toward the insert notch to form a seam notch, or can have a seam web which extends inward toward each insert notch. Another feature which can be incorporated into the ring binder concept of this invention is the idea of a curvable spine. The curvable spine idea involves providing one or more hinge-like spine grooves (641, 642, 643, 644) on the inside surface of the spine portion of the insert between the two hinge grooves. This allows the spine to flatten when the covers are open, but to curve about the longitudinal axis of the spine (concave on the inside and convex on the outside) when the covers are closed.
