Abstract: Abstract of the Disclosure Pullulan forms an association complex with PEG in a hydrous  system.   The  association  complex,  as  well  as  its pullulan and PEG components, exerts a decreased solubility in water.  The association reduces or even eliminates the excess-ively  high  water-solubility,  threading  and  stickiness  of pullulan so that this extends the uses of pullulan and PEG such as those in gradually disintegrable-  and sustained release-shaped articles for consumer's products, toiletries, cosmetics, pharmaceuticals and feeds.

Title: Fabrication of fibre optic components
Inventor: THORNCRAFT DAVID A
IPC: G02B6/38
Filed: 1987-11-13
Granted: 1992-10-20
Abstract: ABSTRACT     Apparatus for fabricating a fused biconical taper fibre optic coupler includes a hollow furnace having a longitudinal slot.  Clamp units are provided to hold at least two suitably prepared optical fibres in intimate side-by-side contact.  The clamp units are moveable by motors to relatively laterally move the fibres into and out of the furnace through the slot.  A power supply heats the furnace to in turn heat segments of the fibres therein while these segments are in intimate side-by-side contact to a temperature sufficient to cause the fibre segments to fuse together.  Drawing units associated with the clamp units longitudinally draw the heated fibres while in the hot furnace to cause each fused fibre to develop a biconical taper and so form a coupler.

Title: Flexible rotary snow tiller
Inventor: BEELEY MICHEAL G
IPC: A01B33/08
Filed: 1987-12-02
Granted: 1991-06-11
Abstract: ABSTRACT OF THE DISCLOSURE       The flexible tiller has a center and two end sections, each including a cutter bar, frame, apron and grooming bar.          The two tiller end sections are connected flexibly to the ends of the center section by frame to frame hinges and by cutter to cutter universal joints, so that the end sections can ro-tate freely about the hinges.  The tiller center section is secured to the towing mechanism to oscillate about a central horizontal axis in the direction of travel.  The oscillating center section and the two pivotally attached end sections cooperate to enable the tiller to closely conform to and thoroughly groom rolling snow paths without reducing them to flat ones.  The rolling paths are enjoyable to ski, and are slower and safer.  A controllable hydraulic ram is mounted to act across each hinge, so that the operator may select the degree of bending permitted at each hinge, and may hydraulically lock it into selected position, if desired.

Title: Electric discharge machining apparatus
Inventor: FUTAMURA SHOJI
IPC: B23H1/02
Filed: 1987-12-17
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE  A  discharge machining apparatus adapted to permit  the supply of discharge current to be cut off without increas-ing electrode consumption.   Arrangements are made to gra-dually  increase the level of  discharge  current,  rather than maintaining the current level of discharge pulse.  By doing so, electrode consumption becomes independent of the pulse  width  of  the discharge pulse,  so  the  discharge current can be cut off immediately after an abnormal state occurs, eliminating the danger of deteriorating the quali-ty of the machining surface of a workpiece.

Title: Weather identification system
Inventor: WANG TING-I
IPC: G01N15/02
Filed: 1988-01-07
Granted: 1991-06-18
Abstract: WEATHER IDENTIFICATION SYSTEM     ABSTRACT OF THE DISCLOSURE     A weather identification system is provided for remotely detecting precipitation and for determining the nature of precipitation in an open environment, as at an aircraft landing field.  The system employs an optical transmitter and receiver, wherein particles of precipitation passing through a light beam from the transmitter cause scintillations which are detected at the receiver.  A drastic reduction in spatial separation between the light transmitter and receiver makes possible the use of a partially coherent light beam in place of a conventional laser beam.  The transmitter and receiver are spaced apart a distance of approximately one meter, and the product of one half of the angle of incoherency multiplied by the spatial separation between the transmitter and receiver is no greater than about 2.5 millimeters.  Rain passing through the light beam produces scintillations with substantial frequency components above one kilohertz.  Snow induced frequencies are primarily below a few hundred hertz. The receiver is coupled to an automatic gain control means and a signal processor.  By measuring the spectrum energy in various frequency bands, and by comparing the ratios of the measurements, the existence of precipitation may be ascertained and the type of precipitation can be identified remotely.
Patent CA-1333652-C (CA)
Inventor: GRUBER HEINZ
IPC: B21D15/04
Filed: 1988-01-07
Granted: 1994-12-27
Abstract: The present invention is directed to a method for forming a screw-thread and a tubular body with a screw thread. The conventional manufacture of an internal thread on a connecting sleeve, which is used as the coupling element for parts of a rock anchor or drilling rod, by shaping, involving cutting, in particular by thread cutting, is characterised by a very large consumption of energy, since considerable cutting work is involved with a rounded thread.  Furthermore, in the preparation by cutting of a screw-thread in this instance of use, it is a disadvantage that because of the notching effect, in the basic region of the threaded section, the durability of the connecting sleeve is adversely affected. According to the invention, a connecting sleeve and a method for its manufacture are proposed, in which the internal thread is made without cutting, by deforming the exterior of the connecting sleeve as a kind of screw-thread so that the copy of this deformation on the inside forms the internal thread to be made.  In conjunction with the increase in strength associated with toughening of the material, due to the non-cutting deformation, which generally is cold-deformation, the further advantage is also given that the requisite deformation can be carried out in a single operation, so that the manufacturing costs of such connecting sleeves can be reduced. It is also an advantage that the external thread of the components to be connected together, cooperating with the internal screw-thread of the connecting sleeve, can have a basic shape which corresponds to the external screw-thread-like deformation of the connecting sleeve.

Title: Modular smoke detector
Inventor: HEBERLEIN G ERICH JR
IPC: G08B17/113
Filed: 1988-05-18
Granted: 1991-08-27
Abstract: ABSTRACT    A modular smoke detector is adapted for mounting in an electrical equipment cabinet.  The smoke detector module is of a standard size and configuration, thereby facilitating mounting anywhere in the cabinet.  A mounting location near the bottom of the equipment cabinet is preferred to better detect the heavierthanair combustion products of smoldering or burning insulation.  The modular smoke detector includes a commercial ionization type detector and a fan.  The fan induces air from the interior of the equipment cabinet into the module.  The fan is positioned such that it does not discharge directly onto the ionization detector to prevent excessive speed of the air through the ionization detector.
