Title: Chip bin assembly including a hollow transition with one dimensional convergence and side relief
Inventor: JOHANSON JERRY R
IPC: B65D88/64
Filed: 1995-01-17
Abstract: A chip bin construction, ideally suited for bins having a maximum diameter of twelve feet or more, uniformly discharges chips, after steaming, without the necessity of a vibratory discharge. A hollow transition portion is provided between a main body which is a right circular cylinder of a first diameter, and a nonvibrating discharge which has a second diameter typically 1/3 or less that of the first diameter. The hollow transition includes a first, uppermost, portion having a generally right rectangular parallelepiped configuration including opposite side faces having generally triangular shapes, and providing one dimensional convergence and side relief; a second portion tapering from a generally rectangular parallelepiped configuration at an upper pan to a generally circular configuration at a lower pan and having opposite side faces having generally triangular shapes which align with said first portion generally triangular shapes to define substantially diamond shaped wall portions. Also, there preferably is provided a third portion substantially the same as the first portion, only smaller, and connected to the second portion lower part; and a fourth, lowermost, portion substantially the same as the second portion only smaller, and connected to the third portion and discharge. Steam is introduced into the main body and the hollow transition, such as through steam conduits in the generally triangular shaped faces of the second portion of the hollow transition. Air blasters are mounted where appropriate in the hollow transition to break up chip hangups.

Title: The manufacture of and uses for low molecular weight agars and agaroids
Inventor: MILLER IAN JAMES
IPC: A23L29/256
Filed: 1994-06-09
Abstract: The invention consists of methods by which agar or an agaroid is hydrolysed under controlled conditions to give materials which form very low strength gels when 1 % solutions in water are cooled, and which, at near zero gel strengths, give dispersions which act like creams.  These can be used as bases for skin treatment products, cosmetics, food and have the advantage for skin preparations of being handled like a cream but then behaving like a lotion, the cream leaving no oily residue. Twelve examples are given, including uses for cosmetics, massage gels, etc., and twenty claims are made.

Patent CA-2187216-A1 (CA)
Title: Channel waveguide and applications
Inventor: RASCH ANDREAS
IPC: G02B6/10
Filed: 1996-02-06
Abstract: The invention concerns an integrated-optical channel waveguide and its applications as switch, modulator, and sensor. The channel waveguide (2) is placed into or onto the flat substrate material (1) and features a geometrically narrowly delimited channel-shaped structure, where the delimitation is located vertical to the propagation direction of the light. A singlemode integrated-optical wideband channel waveguide is described which iscapable of guiding, e.g., light from the entire visible wavelength range in singlemode and effectively, that is, at low optical attenuation, and which thus represents a real singlemode white light channel waveguide. If required, the light can be switched and modulated, wavelength-dependent, or wavelength-independent, e.g. by electro-optical means. The channel waveguide (2) is fabricated by means of basically known processes, e.g. by changing the refractive index. (Figure).

Patent CA-2189664-A1 (CA)
Title: Method and device for optically recovering the synchronism of an optical digital signal
Inventor: FONTANA FLAVIO
IPC: H04B10/564
Filed: 1996-11-05
Abstract: The device and method are based on tapping off a predetermined line  signal  fraction  and  inputting  it, together  with  a  continuous  pumping  radiation,  to  a resonant cavity which comprises a non-linear wave guide.         The value of the pumping wavelength is related to the wavelength of the line signal pulses to produce therewith a four-wave mixing  (FWM)  effect in the non-linear wave guide. In travelling the non-linear wave guide, a clone signal is generated by FWM effect which duplicates the pulse sequence of the line signal at a clone wavelength.          By adjusting the length of the resonant cavity such that, in inputting the line signal,  each of its pulses will come in at exactly a pulse of the clone signal which is being circulated within the cavity, a clone signal can be circulated  within  the  resonant  cavity  whose  pulse sequence represents the optical clock signal sought.

Patent CA-2197542-A1 (CA)
Inventor: RICARD TODD MICHAEL
IPC: H04W88/02
Filed: 1997-02-13
Abstract: A Portable Electronic Device Holder is disclosed.  This holder is supplied with a ceramic self-limiting heater that keeps the rechargeable batteries of a cellular phone or other electronic device at an optimum operating temperature as it is well known that cold adversely effects battery output.  This is accomplished by the use of an insulated pouch-like apparatus into which the electronic device can be placed.  The pouch further contains the self-limiting heater.  This heater heats a conductor plate, which in turn warms the batteries of the device.  Thus, the present invention allows for the normal use of a cellular phone or other device in cold temperatures.
Patent CA-2197630-A1 (CA)
Inventor: SCHMIDGALL JON A
IPC: B28B21/88
Filed: 1997-02-14
Abstract: A collapsible core for concrete pipe making machines that are used in the dry cast process when lined pipe are to be produced. The collapsible core of the invention has a moveable front panel joined to two moveable side panels, all of the panels being connected to hydraulically powered linkage arrangements that will pull the panels straight back from the liner. The collapsible core is constructed so that when moveable panels of the core are retracted to collapse the core, the core panels are guided along radial lines of the core to pull the panels directly away from the pipe liner, thus practically eliminating the friction that causes bulging or pull out of the liner from the concrete pipe.

Title: Apparatus for illumination stabilization and homogenization
Inventor: ORTYN WILLIAM E
IPC: G02B21/06
Filed: 1995-08-22
Abstract: An illumination device provides stable illumination for microscopic evaluations. An arc lamp (22) serves as the light source. An input optical train (12) focuses the light through an aperture stop (26) to place an image of the arc (23) on an input aperture (42) of a light pipe (40). The magnification of the lamp (22) is chosen to reduce variations due to occlusion. The light pipe (40) spatially homogenizes the light while preserving the angular integrity. Another optical train (50) receives the spatially homogenized light (45) and focuses many arclet images (253) to fill the pupil of a condenser lens (30). The condenser lens (30) focuses the exit aperture (41) of the light pipe (40) onto a specimen (300) on a microscope slide (20). A feedback system (60) samples the light (55) and corrects for residual temporal variations by electronically modifying the image as it leaves a CCD (22).

Abstract: On the Internet (106), rather than retrieving a frequently requested Web object from its originating server (105) in response to a request from a client terminal (101, 102), the object rather can be retrieved from a cache (103) within the Internet Access Service Provider (IASP) (104), which connects the client terminal to the Internet. What is stored in the cache may, however, not be the most recent version of the object. Distinct from providing the Web object itself, information about changes to the object is provided by the server in response to a cache request that is asynchronous to a request from a client for the object. Such information about changes to an object includes the date and time when the object was last modified, the byte size of the modified object, and information on the type of content of the object. After receiving this information about changes to an object, the cache may then request that a copy of the object be downloaded to it.
