Title: Distributed photographic system for taking self portraits
Inventor: TEN BRINKE MACHIEL A
IPC: G03B15/00
Filed: 1996-01-24
Granted: 2001-01-23
Abstract: A distributed photographic system for taking self portraits is disclosed which reduces cost as compared to conventional photographic booths by separating image acquisition (10) and image rendering (30) functions. Control over the system is also increased by allowing a remote operator in a commercial setting to remotely govern the image acquisition system. In the preferred embodiment, the image acquisition system utilizes a beam splitter to allow image bearing light to pass through into a video camera which then projects images through a liquid crystal display and back onto the beam splitter which reflects outwardly to the user. The user then can choose which video image the user wishes to have placed onto a hard-copy medium by indicating through a user panel that an image is acceptable. Upon doing so, the image is sent electronically to a remote printing station which is controlled by an operator. The user then goes to that operator to collect and pay for the hard-copy medium, thereby eliminating a need for additional automatic fund collecting systems.

Abstract: A blade is provided for use as either a stationary blade or moving blade in a hair clipper bladeset, the bladeset being constructed and arranged so that the moving blade is pressed against the stationary blade for allowing the moving blade to reciprocate relative to the stationary blade in a transverse direction to a longitudinal axis of the clipper. The blade includes a base portion having a tooth end, and a mounting end opposite the tooth end, a plurality of teeth arranged in spaced, parallel relationship to each other and projecting from the tooth end, each tooth having a tip and a root opposite the tip and being joined to the tooth end. The roots are joined to the tooth end in spaced relationship to each other to define generally planar-floored channels on the tooth end between the roots for facilitating the evacuation of hair and/or hair clippings from a cutting area of the bladeset. The roots of the teeth are configured to have a generally tapering portion so that the planar-floored channels widen in the direction of the mounting ends.

Title: The production of carotenoid preparations in the form of coldwater-dispersible powders, and the use of the novel carotenoid preparations
Inventor: AUWETER HELMUT
IPC: A23L5/44
Filed: 1997-09-12
Granted: 2007-07-31
Abstract: Carotenoid preparations in the form of coldwater-dispersible powders are produced by preparing a molecular-disperse solution of a carotenoid, with or without an emulsifier and/or an edible oil, in a volatile, water-miscible, organic solvent at elevated temperature and adding therein an aqueous solution of a protective colloid, whereupon the hydrophilic solvent component is transferred into the aqueous phase, and the hydrophobic phase of the carotenoid results as nanodisperse phase, heating the resulting hydrosol at from 40°C to 90°C, with or without cooling of the hydrosol to from 0°C to 30°C  beforehand, and removing the solvent and the water from the heated hydrosol, and converting it into a water-dispersible dry powder.

Abstract: La présente invention concerne un procédé de culture hydroponique d'arbres de pépinière. Ce procédé consiste à remplir d'un milieu de charbon de bois fumé ou de balle de riz mélangé à une matière retenant l'eau, un pot de semis en germination, lequel pot comporte des faces latérales pourvues de passages et un fond susceptible de se fracturer. Le procédé consiste ensuite à plonger le pot dans une solution de culture dont les composants sont l'azote à raison de 1000 à 1800 ppm, l'acide phosphorique à raison de 600 à 1000 ppm, le potassium à raison de 1500 à 3500 ppm, le magnésium à raison de 300 à 500 ppm, et de la craie à raison de 900 à 1400 ppm, et ainsi à faire pousser l'arbre de pépinière au moyen de cette solution de culture. Ce procédé favorise et accélère la croissance de l'arbre de pépinière, même après transplantation de l'arbre de pépinière dans le sol. En outre, ce procédé donne des résultats avantageux, l'arbre cultivé de cette façon présentant notamment de faux cercles de croissance, et donnant normalement un bois d'oeuvre aux bonnes qualités de densité et de teinte. Ce procédé convient particulièrement à la culture d'arbres de pépinière destinés au reboisement.

Abstract: La présente invention a pour objet un rasoir électrique à mouvement rotatif comportant une ou plusieurs têtes flottantes à zones de coupe annulaires concentriques. Les zones de coupe extérieures sont de plus grande épaisseur que les autres zones de coupe, et les fentes d'entrée des poils orientées dans le sens radial sont formées dans les zones de coupe, formant ainsi des fentes de coupe de forme allongée. Les fentes de coupe de forme allongée à l'intérieur des zones de coupe autres que la zone de coupe extérieure sont donc de plus faible épaisseur que celles de la zone de coupe extérieure, ce qui permet un rasage de plus près tout en conférant à la tête de coupe la résistance appropriée.

Abstract: A system for, and method of, generating an alias source address for an electronic mail ("e-mail") message having a real source address and a destination address and a computer network, such as the Internet, including the system or the method. In one embodiment, the system includes an alias source address generator that employs the destination address to generate the alias source address. The system further includes an alias source address substitutor that substitutes the alias source address for the real source address. This removes the real source address from the e-mail message and thereby renders the sender, located at the real source address, anonymous. Further-described are systems and methods for forwarding reply e-mail and filtering reply e-mail based on alias source address.

Abstract: A controller instructs a spindle motor to start rotating, and instructs a servo control section to start a focus servo control.  When a light beam crosses information tracks on an optical disc with a rotation of the optical disc, an amplitude indicating signal generating section detects changes in the amplitude of a readout signal output from an optical pickup.  A disc type identifying section identifies types of optical discs having different track pitches of the information tracks in starting the rotation of each optical disc based on the peak value and bottom value or the amplitude of the readout signal.  Consequently, the types of optical discs having different information recording densities, particularly different track pitches, can be identified at an early stage without waiting for reproduction of information recorded on each optical disc.  It is therefore possible to shorten the time for starting an optical disc device, or prevent an increase in the starting time.

Abstract: A peripheral interconnect for a computer system comprising a bridge, a peripheral bus, and a peripheral device, wherein at least one of these components is adapted to selectively operate in either a high performance mode or a low performance mode, the high performance mode using a first operating speed and a first protocol, and the low performance mode using a second operating speed which is lower than said first operating speed, and a second protocol which is different from the first protocol. The disclosed embodiment provides a high performance mode with a 100 MHz speed and a protocol that disallows pacing, and a low performance mode that uses a 66 MHz or 33 MHz speed and a standard PCI protocol that allows pacing. The high performance operating speed can be twice the low performance operating speed, by doubling the clock frequency and clocking data on only one clock edge, or by clocking data on both a rising edge and a falling edge of a clock signal while operating at the lower clock frequency. High performance adapters can provide split transaction capability, with a high performance bridge having the ability to support split transactions or alias split transactions to delayed transactions. Backward compatibility may also be provided for optional features such as hot-pluggability.
