Title: Powdered cooked cured-meat pigment which is a non-nitrite meat preservative
Inventor: SHAHIDI FEREIDOON
IPC: A23L1/275
Filed: 1991-10-24
Abstract: The pigment, i.e. a mono- and/or di-nitric oxide hemochrome responsible for the color of cooked cured-meats has been prepared from red blood cells, directly or indirectly through a hemin intermediate. The process for preparing this pigment includes the steps of reacting bovine or hog red blood cells with a nitrosating agent and with at least one reductant, at a suitable elevated temperature, to provide a cooked cured-meat pigment, and drying the cooked cured-meat pigment by spray-drying, drum-drying or freeze-drying techniques. The improvement of the present invention involves stabilizing the cooked cured-meat pigment by the step of: treating the cooked cured-meat pigment with a treating mixture of (i) a wall material which is one or more of a starch, a modified starch, a starch polymer, a starch derivative, starch products, N-LOK, maltodextrins, or Schardinger dextrins, e.g. .beta.-cyclodextrin, (ii) a binding agent which is a gum and/or glycerin, and (iii) an additional agent which is an individual one, or is a mixture of, a reductant and a sequestrant; thereby to provide a stabilized CCMP product or a PCCMP product. The preformed pigment, as such or in the encapsulated form, when added to meat prior to cooking reproduces the typical color of nitrite-cured product.

Filed: 1991-11-14
Abstract: 2096344 9208357 PCTABS00013 A method is provided for controlling the growth of weeds by applying to the weeds a herbicide, or other chemical agent, and a culture medium in which microorganisms such as bacteria or fungi have grown. The herbicidal action of the chemical herbicide when combined with the conditioned medium is greater than the herbicidal action of the herbicide alone. This makes it possible to control a broad range of weed species using lower levels of herbicide than are needed when the herbicide is used alone. The medium may be processed to concentrate it or to partially purify it, but it is not necessary to identify or to purify the specific agents in the medium that act to enhance the actions of the chemical agent.

Abstract: ABSTRACT            DRILLING APPARATUS           In order effectively to aid the drilling process by the flow energy of a flushing agent in the creation of a borehole, a drill head is proposed which comprises a short, plate-type drilling crown (10) and a drill pipe element (11) connected thereto, wherein a one-piece insert (15) of a suitable plastics material is provided which is composed of two cylindrical parts (17, 17') which make substantially sealing contact with the central bore (12) of the drilling crown (10) and with the flow passage (13) of the drill pipe element (11) respectively.  The insert (15) has a flow passage composed of two successive bore sections (18, 18'), in which the bore sections narrow in the direction towards a central outlet with different conicity.  In this way one can achieve a low-loss conversion of a part of the flow energy carried by the flushing agent into kinetic energy which is effective during the drilling process at a region which is immediately adjacent to the cutting edges of the drilling crown (10).

Abstract: RECIPROCATING ENGINE            Abstract of the disclosure A reciprocating engine has a disk flywheel on the crankshaft for smoothing the unevenness of the torque. A second flywheel, mounted in a freely rotatable manner on the crankshaft, is coupled by a friction clutch to the disk flywheel.  The clutch is operated by an actuator controlled by a control device which processes signals from sensors.  In steady state operation of the engine in the low speed range the second flywheel is engaged.  Upon acceleration and in the range of high speeds the second flywheel is disengaged.  The engine thus runs smoothly at low speed.  However, it accelerates faster than a comparable conventional engine and has a better braking action.  In driving operations in a vehicle after braking, part of the kinetic energy of the flywheel can be used to accelerate the vehicle.

Patent CA-2116269-A1 (CA)
Inventor: DUDDERAR THOMAS D
IPC: H05K3/34
Filed: 1994-02-23
Abstract: The present invention is embodied in a technique for precise and accurate heightcontrol in fabricating solder bumps or joints formed from a solder bump or bumps. A solder bump is formed by reflow of a conical solder body having base diameter D,height H and cone angle .THETA., and has truncated sphere shape, with height h and truncation diameter d. We have found that D, H, and d can be selected such that ?h/?H is small (typically ? 0.5), indicative of relative insensitivity of the bump height to variation in the height of the conical solder body. The inventive process is also applicable to a component (e.g., a laser) solder-bonded to a substrate, and can provide previously unattainable control of the spacing between component and substrate.
