Title: Apparatus and method for generating diffractive element using liquid crystal display
Inventor: LONG MICHAEL D
IPC: G06K19/16
Filed: 1997-10-01
Granted: 2006-12-19
Abstract: Apparatus and method for recording diffractive high resolution graphical information is suited to recording information that would be difficult to counterfeit. In one embodiment, light is selectively passed by a shutter (52), and through spatial filter (54) to remove noise. Liquid crystal display (68) or similar display device receives a data stream from computer (20) and displays periodic structure(s), diffracting the incident beam into one or more diffracted beams (59). Lens (78) focuses an image of the macroscopic pattern formed of these periodic structures to a recording material in image plane (80) where diffracting structure(s) caused by the overlap of some or all the diffracting beams and, optionally, the undiffracted beam, is created. Optional mask (76) block s some or all of the diffracted and undiffracted beams. The recording material is moved and the process repeated with another pattern of periodic structures until the desired macroscopic image is composited.

Abstract: The permissible degree of opening of a cabinet door is limited by the internegagement between a cover member for an upper door hinge and abutment structure carried by the door itself. In a preferred embodiment of the invention, the abutment structure is defined by another cover member that is secured upon an upper portion of the door. The hinge cover member is provided with a tab that projects into a cavity or recessed section of the door cover member and a portion of this projecting tab is directly engaged by a portion of the door cover member to limit the permissible angular door movement. Furthermore, the hinge cover member is preferably mounted for movement relative to the cabinet. In the preferred embodiment, the hinge cover member is pivoted in direct response to engagement with the first abutment portion of the door cover member and the door is prevented from further pivotal movement when the first abutment portion of the door cover member engages a stop portion defined by the projecting tab of the hinge cover member.

Abstract: Figure 3 is a simplified view of a Hopkinson bar or pressure bar bundle system (101) comprising an input bar bundle (103) having input bars (103a) and an output bar bundle (104) having output bars (104a). A brittle test specimen (102) is positioned in between the bundles (103, 104). Means is provided to induce a one-dimensional compression force C into the Hopkinson bar bundles. Instrumentation is introduced onto the bars (103a and 104a) for measuring values of shear wave or crack propagation. The specimen (102) may be placed under different stress conditions measured by appropriate instrumentation on the bar bundles (103, 104). Figure 6 shows a rod gauge (500) glued to a rock massive R arranged to measure wave effects generated in the rock massive. Other arrangements provide amplification of these wave effects prior to measurement by instrumentation (e.g. 502) on the gauge (500).

Abstract: Il est possible de prévenir et de traiter les effets néfastes du temps sur la peau humaine (c.-à-d. le vieillissement de la peau humaine dû à l'âge) par l'application topique d'un rétinoïde, de préférence du rétinol. Il a été découvert que certaines voies (à savoir les voies activées par le stress, SAP) activées au cours du photovieillissement de la peau humaine (c.-à-d. le vieillissement cutané prématuré photo-induit) sont, de façon similaire, également élevées dans la peau de personnes âgées; il a également été découvert que d'autres voies (à savoir la voie ERK activée par mitogènes) sont faibles dans ladite peau. Le traitement de peau de personnes âgées à l'aide d'un rétinoïde permet d'inhiber la dégradation de collagène dermique et de favoriser la synthèse de procollagène. Des coupes de biopsies de peau de personnes âgées (plus de 80 ans) montrent qu'un seul traitement peut permettre d'accroître l'épaisseur de l'épiderme, d'améliorer la densité de collagène dermique, et d'activer la formation de fossettes de la couche de Malpighi et de papilles dermiques (voir fig. 3), et peut permettre de réduire la quantité de c-Jun et d'accroître les quantités de procollagène de type I et III (voir fig. 18). De tels avantages sont également utiles pour prévenir des contusions, dilacérations, et ulcérations de la peau de personnes âgées.

Abstract: An amplifier with feedforward loops for rejecting non-linear distortion and control circuitry for such amplifier and employing a distortion compensation method. A signal from a dominant path is input into a synchronizing detector via an ALC circuit as a reference signal. Using this reference signal, an error signal output from a distortion rejection loop is subjected to synchronizing detection. An offset voltage of a mixer inside the synchronizing detector can be prevented from varying due to change in local level. Outputs from synchronizing detectors are used for control to optimize corresponding loops. As a pilot signal for a distortion detection loop can be eliminated, undesirable spurious effects due to such a pilot signal is avoided. The acquisition time of each of the loops can be shortened because an optimizing control using a step-by-step procedure under CPU control can be eliminated.

Title: Electric heater for a livestock water tank
Inventor: REUSCHE THOMAS K
IPC: A01K7/02
Filed: 1999-12-07
Granted: 2007-06-05
Abstract: An electric water tank heater is installable through the drain plug opening of a water tank. The heater includes a power cord interconnected with a heating element through a temperature control device for delivering electrical power to the heating element in a controlled fashion. A housing hermetically seals the interconnection between the heating element, the power cord and the temperature control device The power cord extends through the drain plug opening of the tank and terminates in a conventional male plug that is configured for insertion into a reciprocal power outlet. The power cord includes detachable connector interposed between the heating element and the male plug. The connector is smaller than the electrical plug, and, as a result, the heater may be installed through drain plug openings that are too small to permit the passage of the electrical plug. The connector can be positioned anywhere along the length of the power cord, and integrally formed with the male plug or the heater housing.

Abstract: Air is replaced with an insulating gas during the manufacture of an insulated glass unit, the glass unit having two parallel glass panes (74, 76) and a peripheral spacer (78) between them and defining an interpane space. An air replacement apparatus comprises first and second platens (12, 14) movable toward and away from each other, at least one carrying a peripheral resilient seal (38) that extends toward and peripherally seals to the other platen to define between them a sealed enclosure. A conveyor (46) moves a partially assembled insulating glass article into a gas replacement position between the platens, one pane (76) being separated from the spacer (78) at its bottom edge (86). The platens (12, 14) are closed upon each other to seal between them the glass article, an isulating gas being introduced into the enclosure and a mixture of insulating gas and air being exhausted from the enclosure. Further movement of the platens (12, 14) closes the lower edge (86) of the one glass pane (76) against the spacer (78) to seal the interpane space, the platens (12, 14) thereafter being opened and the completed glass article conveyed outwardly from between them.

Abstract: An improved astragal assembly for double door entryways includes an extruded aluminum frame into which upper and lower flush bolt assemblies are slidably disposed. The flush bolt assemblies include a relatively long metal bolt about which is injection overmolded a series of retainer guides, which ride in the frame. Locking mechanisms are also integrally overmolded onto the bolts. The frame and all components of the astragal assembly are symmetrical and reversible so that the assembly is non-handed; that is, it can be adapted to both a right hand swing and a left-hand swing inactive door. A unique strike plate mounting system and bottom-sealing block are provided and the upper end of the assembly includes means for sealing against the stop of a head jamb. Drafts at the upper and lower inside comers of the doors of a double door entryway are thus prevented.
