Title: Nut butter
Inventor: WONG VINCENT Y L
IPC: A23L25/10
Filed: 1990-04-27
Abstract: Abstract Disclosed is a nut butter spread composition, having a Casson plastic viscosity value of less than 12 poise comprising from 25% to 55% peanut oil, or other fat component, and from about 40% to about 67% nut solid particles which have been processed to a particle size distribution in which at least 80% have a particle size less than 18 microns, and preferably between about 2 and about 11 microns.  The surfaces of the protein and starch bodies of the nut solids are smooth due to a reduction of cytoplastic reticuli surrounding the protein bodies.  The particle size distribution is monodispersed, i.e. a curve with a single peak.  A process for preparing these particle size peanuts using a roll milling process which can be followed by a separate smearing step is also disclosed.  A low fat peanut butter having from 25% to 40% peanut oil is the preferred nut butter.

Inventor: SAGE BURTON H JR
IPC: A61K45/08
Filed: 1991-03-12
Abstract: Methods for enhancing the delivery of an active ingredient to the vasculature of an animal by iontophoresis have the steps of adding a vasoactivator to a formulation with an active ingredient, coiontophoresing the vasoactivator and the active ingredient into the skin of an animal and establishing a concentration of the vasoactivator in the skin near the upper capillary loops thereof so that the blood flow is changed therethrough. The vasoactivator effectively changes the blood flow in the upper capillary loops of the vasculature in the skin of an animal.    If the vasoactivator is a vasodilator, the blood flow is increased and when the vasoactivator is a vasoconstrictor, the blood flow is decreased. The specification discloses iontophoretic delivery apparatus for use with a formulation for controlling iontophoretic transdermal administration of an active ingredient into the blood stream of the vasculature of an animal, and discloses methods and compositions for enhanced iontophoretic delivery of active agents. The compositions are pharmaceutically acceptable compositions for iontophoretic delivery comprising a delivery enhancing amount of a vasodilator or vasoconstrictor and active agent.

Abstract: ABSTRACT OF THE DISCLOSURE            A waste collecting and recycling system where a portable waste sorting apparatus is located at a first collecting location.  Waste from a nearby locality is brought to the collecting location where the recyclable material is sorted out and carried to another location for recycling or possibly further shipment.  Then the portable separating apparatus is moved to a second collecting location and the process is repeated.

Thus, efficiencies are realized in transportation costs and also in effective use of the sorting apparatus.
Patent CA-2040685-A1 (CA)
Title: Roll angle determination
Inventor: HANSEN AAKE
IPC: F41G7/30
Filed: 1991-04-17
Abstract: The invention relates to an arrangement for determining the roll angle position of a rotating projectile, shell, missile or the like with the aid of polarised electromagnetic radiation, comprising a transmitter arranged to emit a position-determining polarised radiation in the direction towards the projectile and a receiver arranged in the projectile in order to receive the transmitted radiation. The emitted radiation consists of two components, on the one hand a component in the long-wave band and on the other hand a component in the microwave band. The micro-wave component comprises a pulse train in which the pulses are intended to indicate whey the long-wave component is situated in a certain phase position, for example to indicate the sinusoidal long-wave component's zero cross-overs with a positive-going derivative. This takes place in such a way that a synchronising pulse is emitted by -the long-wave transmitter to the microwave transmitter which transmits a short series of microwave pulses as an indication to the projectile.

Filed: 1991-07-11
Abstract: A method is disclosed for controlling the movement of hydraulically movable work equipment that is arranged at the end of a length-adjustable and pivotable arm, along a substantially rectilinear path of movement, the work equipment being moved with the assistance of hydraulic drive units that act on the arm in dependence on input control signals (in1, in2, in3) that determine the path of movement.   A path control arrangement suitable for implementing the method is also described.     Even in the case of non-ideal control loops for the control of the drive units, it is intended that the work equipment be moved along a desired path.     For that purpose, starting from an actual position of the work equipment, a sequence of desired positions in the path of movement is ascertained and the work equipment is moved from an actual position to the next desired position, the movement into the next position not being initiated until the work equipment is located in a predetermined tolerance band about the preceding position .

Title: Method and system for controlling a travelling body so as to move forward along the predetermined route of the movement of travelling body
Inventor: FUJIMORI ISAO
IPC: G05D1/02
Filed: 1991-07-11
Abstract: ABSTRACT OF THE DISCLOSURE When controlling a travelling body so as to move forward the travelling body along the predetermined route, the distance and direction of deviation of a body of the travelling body from the predetermined route are measured, the above measured distance and direction of deviation of the body from the predetermined route are inputted as an observed value into an antecedent operation part in which the membership functions corresponding to distances of deviation of the body from the predetermined route are prestored. Then an operation of grade at the antecedent, namely a degree that an operator has a feeling that the above deviation is small or medium or large is performed. An operation of manipulated value in the consequent is performed by inputting the obtained grade into a consequent operation part in which the membership functions corresponding to manipulated values are prestored. The obtained manipulated value is outputted into the steering means. The steering means is controlled according to the manipulated value. By means of the above mentioned method, an operator can automatically control the travelling body so as to move forward along the predetermined route without the help of veteran operator.

Abstract: Title:     AN IMPROVED PROCESS FOR POST-TREATMENT OF PRE-SERVATIVE-TREATED WOOD     Abstract of the Disclosure An improved process for post-treatment of oil-borne preservative treated wood is described. More particularly, the improved process comprises, in one embodiment, the steps of (A) contacting the preservative-impregnated wood in a closed vessel with steam and collecting a water condensate generated in the vessel; (B) applying a vacuum which is sufficient to allow refluxing of the water condensate to remove at least some surface deposits and distillation of the water out of the vessel;             (C) releasing the vacuum; (D) recovering the post-treated wood from the vessel. The invention uses a method of steam-cleaning that requires less time, less water and lower temperatures, and the method results in a simulta-neous separation of the steam condensate from the oil-preservative solution.
