Title: Automatic lubricant supplying method and an apparatus therefor
Inventor: YAMAMURA MASATO
IPC: B29C45/83
Filed: 1990-08-15
Abstract: ABSTRACT OF THE DISCLOSURE      A method for automatically timely supplying a lubricant to a machine working section driven by a motor and an apparatus therefor.  The quantity of increase of the driving current of a mold clamping servomotor (12) during the process in which a mold clamping mechanism (10) of an injection molding machine shifts from a proper lubrication state to an improper lubrication state is previously decided for each combination of the type of the injection molding machine, injection molding conditions, and the type of grease.  While a normal injection molding cycle in the proper lubrication state is being executed, a reference value for the motor driving current is decided on the basis of the normal motor driving current in a specific moved position of a movable platen (14), at which the motor current is measured for the aforesaid decision, and the increase of the motor driving current, the reference value and the specific moved position of the movable platen being loaded into a memory of a numerical control device (50).  In response to a grease supply timing command, the control device drives a grease pump (40) if the detected value of the motor current in the specific moved position of the movable platen is not smaller than the reference value.  Grease from the grease pump is supplied to a predetermined quantity to each of a plurality of parts of the mold clamping mechanism through a distributor (43).

Abstract: A method and apparatus for processing waste plasterboard consisting of sheets of paper or similar material adhered to a core of plaster of paris or the like, for recovering and separating the cover material from the gypsum of the core and for collecting each in a conveniently reusable form.  A pair of rollers have para-llel axes of rotation and are held to a variably close spacing under pressure while being counterrotated to grasp and crush pieces of plasterboard, delivering the paper and crushed gypsum core material to a vibrating screen which separates the two for separate collection and subsequent reuse as raw materials or for other purposes.  A second crusher and screen may be used for additional separation of the materials.

Title: Conversion of methane
Inventor: HAN SCOTT
IPC: C07C31/04
Filed: 1991-04-15
Abstract: CONVERSION OF METHANE                        ABSTRACT   A mixture of organic compounds comprising a major amount of liquid hydrocarbons, mostly aromatic, is formed by the direct partial oxidation of methane in the presence of a ZSM-5 catalyst. The reaction conditions are substantially the same as those required for the direct homogeneous partial oxidation to methanol.  However, liquid hydrocarbon formation depends on the presence of a small amount of an impurity such as propane or propylene in the feed; in the absence of such, only methanol is formed.  With such modifier present, controls of reaction parameters, e.g., temperature, permits synthesis of both methanol and liquid hydrocarbons in desired proportions.          Properly processed natural gas can serve to provide methane and at least  part of the reaction modifier.

Patent CA-2062112-A1 (CA)
Inventor: DILLON LARRY S
IPC: F04B47/02
Filed: 1992-03-02
Abstract: A manual pumping apparatus for the delivery of water from a deep well to the ground surface. The pumping apparatus consists of a surface mounted drive unit, a handpump lever operated handle, a sub-surface pump unit, and a water filled flexible riser pipe connecting the drive and pump units. The pumping operation is commenced by the downward movement of the handpump lever handle which forces a drive unit piston disc downward by means of connecting linkage rod. Water is forced down the flexible riser pipe below the piston disc closing a check valve on the upper end of a hollow pump rod to increase water pressure and hydraulically force the pump rod to slide downward and compress a helical coil spring located at the base of the pump unit. Leather seals on the piston discs and one way check valves at each end of the hollow pump rod prevent water leakage between pump components and maintain the driving force due to the increasing water pressure in the handpump system. As the increased water pressure compresses the helical coil spring and forces the lower piston disc downward, a check valve opens and permits water to enter an expanding volume of space, or storage chamber, between two pump unit reservoir cylinders of different diameters. The upward movement of the handpump lever handle releases the water pressure allowing the compressed helical coil spring to expand which forces the storage chamber water up the riser pipe to the drive unit reservoir cylinder and out the discharge nozzle. The deep well handpump is designed to be simple to operate, inexpensive to manufacture with readily available parts, easy to maintain and repair, and capable of extended periods of reliable operation. The use of a flexible connecting riser pipe between the drive and pump units for energy transfer and water flow is a significant improvement over the common method using of a metal connecting rod which is subject to mechanical breakdown. The deep well handpump will be useful in rural areas of under-developed countries where simplicity and reliability are important, and where maintenance can best be done by local labour with few tools using simple components.

Abstract: Abstract of Disclosure This invention relates to a method for manufacturing a sack or bag with a bottom being rectangular in the filled state and with a handle portion, and it also relates to sacks or bags manufactured in accordance with this method. For the solution of the problem to simplify already known methods, onto a continuously advanced flat web two strips of sealing-wax which are in parallel to each other and perpendicular to the lateral edges are applied on one side at distances of one bag length, respectively, and at corresponding locations of the back side of the flat web four short strips of sealing-wax are applied, and between the strips of sealing-wax two rein-forcements are glued thereto with their whole surface. Below the first reinforcement a folded sheet with a leg is glued, whereas the other leg is folded back thereonto. Below the second reinforcement an area is provided with glue which in size corresponds to the leg. On one side of the flat web an adhesive strip is applied. By forming lateral folds the web is folded to a tube such that the free leg is arranged on the glued area and that simultaneously the two reinforcements are arranged above each other. The sealing-wax strips are reactiva-ted and fold edges are pregrooved. Finally, in the section of the reinforcements lying on top of each other a griphole is punched. The still open bottom is folded to be closed in the usual manner after filling of the bag.
