Title: Method for sealing retort container
Inventor: OKAMOTO HIDEFUMI
IPC: B31B50/64
Filed: 1991-02-28
Granted: 1999-04-27
Abstract: A method for sealing a retort container comprises the steps of heat-sealing an opening of a retort container after charging contents into the container so that a line-seal having a width ranging from 0.5 to 2.5 mm is formed to thus seal the container and then performing knurled sealing at a portion including the line-seal. The sealing method can provide a container having sufficient seal strength and does not spoil the beautiful appearance of the flange portion of the container even if contents thereof remain in the flanged portion or the like. Moreover, the method does not cause foaming in the sealed regions at all and it is not necessary to perform the sealing treatment under substantially severe conditions to prevent the occurrence of the foaming and, therefore, the method can provide containers having a sealed portion easily peelable.

Title: Powder coating method for metallic surfaces
Inventor: BOHNACKER ULRICH
IPC: B05D3/02
Filed: 1991-09-19
Granted: 2000-08-22
Abstract: An electrostatical powder coating method starts out from a metallic surface provided with an oil film as a protection against corrosion during storing and transportation. Resin powder is applied to the surface without prior removal of the oil film. The powder layer is melted in a furnace and subsequently hardened by cooling. It is preferred that an amonut of heat is supplied by the furnace which is sufficient to evaporate the oil. Preferably, an oil is used which is stable during heating as long as it remains on the work piece surface.     This includes the possibility that all of the oil or at least some components thereof diffuse and evaporate through the powder layer during heating or, alternatively, that part or all of the oil remains on the work piece during the heat treatment and mixes with the powder layer. In both cases the quality of the resin coating is not deteriorated by the oil film.

Title: Device for automatically clamping on the pole of a shaft trolley, a grasped element to which a shaft is suspended
Inventor: LEBRE CHARLES JEAN PIERRE
IPC: B66F9/18
Filed: 1992-07-24
Granted: 1996-03-26
Abstract: The upper and lower jaws are joined to a double yoke surrounding the pole.  An auxiliary yoke imprisoning a clamping plate is slidingly mounted on the pole above the double yoke and is connected to the latter by means of a compression spring.  On the yoke, a connecting rod is slidingly mounted and joined at its intermediate portion to a thrust lever having one extremity joined to the auxiliary yoke and engaging the clamping plate.   The weight of the shaft transmitted by the jaws to the double yoke automatically pushes the lever onto the plate and thus immediately immobilizes it by clamping the device along  the pole.    Activation  of  the  spring  controls clamping of the plate in the absence of any load, whereas a push applied along a predetermined direction on the handle of the lever annuls the action of the spring and allows the device to slide freely.   The invention is applicable to trolleys ensuring suspension of shafts for their handling operations.
Patent CA-2075371-C (CA)
Title: Hydraulic pressure regulator
Inventor: SCHIEFER ROLF
IPC: G05D16/10
Filed: 1991-12-02
Granted: 1999-10-05
Abstract: Described is a hydraulic pressure regulator with automatic self-relief. A control piston disposed in a regulator housing between an inlet pressure chamber and an outlet pressure chamber for a hydraulic medium is adapted to be doubly acted upon. The inlet pressure of the hydraulic medium to be regulated on the one hand and a resilient control pressure force on the other hand act on the control piston.      The control piston has on its side towards the inlet pressure a smaller piston surface on a lower projecting piston part and a larger piston surface provided on an upper piston part. The lower piston part has a flow duct for the hydraulic medium, which opens beneath the larger piston surface into an upper annular groove of the control piston and which opens into a lower annular groove at the lower piston part laterally at a spacing relative to the smaller piston surface.      Upon a reduction in the resilient control pressure force the control piston is moved into a position in which the flow duct is closed relative to the inlet pressure chamber. At the same time a pressure relief chamber for the hydraulic medium obtaining on the outlet side of the control piston is opened. With the hydraulic pressure regulator, when the medium ceases to be taken off out of the outlet pressure chamber the pressure in the outlet pressure chamber can be reduced or brought to zero.

IPC: A01M7/00
Filed: 1992-10-23
Granted: 2003-05-13
Abstract: A thin invert composition and method for applying agricultural products to a target area with minimal drift or evaporation is based on a water and oil mixture which is emulsified by minimal agitation so as to provide a low viscosity emulsion. The emulsion, when sprayed through small spray orifices (e. g., 0.020 inch internal diameter) forms a thin invert wherein the water phase is enclosed in the oil phase and the droplet size is small (e.g., 1000 microns mean diameter) and uniform. The water phase carries a hydrophilic active agricultural product. The mixture can have 20 to 50% oil phase by weight, and 50 to 80% water phase by weight, the water phase containing the active hydrophilic product of up to 75% by weight of the water phase. According to the composition and the method disclosed, the surface tension of the droplets formed when spraying is the primary factor determining droplet size, and is kept small and uniform for thorough application to leafy surfaces and the like.

Granted: 1995-12-26
Abstract: It  is common on highways for trailers or self-propelled vehicles to utilize and rely on wheels which are filled with pressurized air.   Such pressurized wheels are subject to loss of air pressure for a variety of reasons. This invention relates to a detection device which is secured unto an axle and near a wheel, located either on a trailer, or a self-propelled vehicle, and by its workings, able to detect when a sufficient loss of air pressure has occurred in the tire of the approximated wheel, and thereafter continuously able to alert the operator of potential danger due to the loss of air pressure.  Similar detection devices would be attached near each wheel and would provide maximum detection for a vehicle or trailer.  The audio and/or visual warning triggered by the detection device would indicate for the operator to quickly slow down and safely stop to give visual inspection to the pressurized tire and determine the next step of action, thereby avoiding a potential danger to lives and/or property, which can occur when an undetected loss of air pressure leads to  a  tire  separation  or  other  tire  malfunctions  while travelling on a road way.
