Title: Catalyst component and catalyst for the production of very high molecular weight polyolefins
Inventor: MASI FRANCESCO
IPC: C08F4/60
Filed: 1989-09-06
Granted: 1995-02-14
Abstract: A solid catalyst component for the low-pressure polymerization of ethylene and C3-C10 alpha-olefins into very high molecular weight polyolefins is in the form of a spherical granular solid having a surface area of between 20 and 40 m2/g, a mean pore radius of between 5,000 and 40,000 A and a porosity of between 40 and 90 vol %, and is definable by the following formula (in atomic proportions):    X (1), Mg (1-8), Al (0.2-0.8), Cl (5-20), (Et+OEt+OR) (1-3); where: X = Hf or Zr; Et = ethyl group; OEt = ethoxy group; and OR     = alkoxy group containing from 2 to 8 carbon atoms in the linear or branched alkyl portion.          Such a catalyst component is obtained by preparing a solid spherical granular support by spray-drying an ethanolic solution of magnesium chloride, reacting said support with a hafnium or zirconium alkoxide or halogenalkoxide, and finally reacting the thus treated support with an alkyl aluminium chloride.

Abstract: BIMETAL LOCK ARRANGEMENT FOR A SELF-CLEANING OVEN LATCH                        ABSTRACT A self-cleaning oven door latching mechanism is provided with a locking arrangement responsive to the oven cavity temperature, which includes a locking pin moved by a snap action bimetal member mounted in thermal communication with an oven cavity wall.  The bimetal member moves the locking pin to a locking position when the temperature sensed by the bimetal rises above the locking temperature.  In its locked position the locking pin prevents the opening of the latch until the temperature in the oven cavity falls below the locking temperature.  In its locked position the locking pin also actuates a lock switch electrically connected in parallel with a thermal limit switch.  The thermal limit switch provides over temperature protection for the cavity when operating in the normal cooking modes.  When actuated, the lock switch shunts the limit switch thereby enabling the temperature in the cavity to rise to the self-clean range.  If the locking pin fails to move to its locked position, the limit switch limits the temperature in the cavity to a level at which the door may be safely opened.

Abstract: A method in the operation of mixing or processing plants, where samples are taken from various material supplies, and sampling means for use therewith.                  A B S T R A C T:      In certain mixing or processing plants a successive dosing out of materials from various silo outlets (8) is effected to different places of a belt- or binweigher (2), and material samples are taken out at the respective outlets. For an automatic sampling it will be very expensive to arrange for sampling units at each outlet, but according to the invention use is made of a single sampler (44), which stretches all over the width of the receiving weigher and is movable longitudinally thereof, such that it can be moved into operative connection with any one of the outlets. The sampler (44) is designed so as to be able transfer, after each sampling, the actual sample to a pneumatic conveyor system (20, 22) operating to bring the sample to a central analysing station. The sampler is made as a worm conveyor in a slotted tube (44), which can be turned into an inactive position, in which the sampler can pass through a material flow without collecting material therefrom, and in which it is emptied for residues of previous samples.

Abstract: TELEPHONE LINES OVERVOLTAGE PROTECTION APPARATUS               Abstract of the Disclosure Overvoltage protection arrangements are pro-vided for a pair of telephone lines effective for sup pressing noise and transient voltage signals occurring above data and voice signals carried on the telephone lines and that provides common mode signal rejection and avoids current flow between the telephone lines responsive to common mode voltage signals on the lines so that audible hum is avoided.  The overvoltage protection arrangements include first voltage clamping circuitry for clamping voltage signals on the lines at a first predetermined voltage potential and second voltage clamping and filter circuitry for clamping voltage signals on the lines at a second predetermined voltage potential and for filtering noise and transient signals from the voltage signals only when the voltage signals exceed the second predetermined voltage potential.  The second voltage clamping circuitry provides common mode signal rejection and substantially avoids current flow between the lines responsive to common mode voltage signals on the lines.

Title: Chromatically corrected directional diffusing screen
Inventor: HOCKLEY BERNARD S
IPC: G02B5/32
Filed: 1990-01-22
Granted: 1995-07-25
Abstract: A holographic diffuser provides a high degree of chromatic correction, or color balance, within a selected eyebox and the ability to generate more than one specific eyebox for multiple observer applications. The strength of these gratings can be varied to modify the diffraction efficiency for each colorso that the balance of colors can be varied within the eyebox. This balancing of colors can be used, for example, to compensate for color imbalance within the light source or image generator. Illuminating a first holographic medium produces a first real image of a diffusing screen in a define eyebox. A second hologram is recorded in the holographic medium using the real image produced by the first hologram as an object such that when the holographic medium is illuminated, it produces a second real image of a diffusing screen in the define eyebox. A third hologram is recorded in the holographic medium using the second real image as an object. The third hologram is formed by multiple exposures of the holographic medium with a plurality of selected spectral components. The plurality of selected spectral components comprises optical wavelengths that may correspond to the colors red, green and blue, respectively. The third hologram may be formed by exposing the holographic medium with a single optical wavelength with first, second and third angles of incidence being selected for each exposure of the holographic medium to the optical wavelength.
