Patent CA-2127051-C (CA)
Inventor: SAHLBERG KARL M
IPC: B65G27/14

Granted: 1997-10-21
Abstract: A vibrator is provided herein for transporting articles. The vibrator has a base, a sliding carriage having an article-carrying surface, and a piston arrangement disposed in a piston cavity for reciprocating movement in opposite directions between two positions, the piston arrangement bearing on the carriage. At least one seal is disposed between the piston arrangement and the piston cavity. The piston arrangement, the seal and the piston cavity form two expansion chambers that are respectively enlarged and contracted with movement of the piston arrangement. The manifold communicates with the inlet, with the vent, and with the expansion chambers for supplying air to, and exhausting air from the expansion chambers. A mechanism is disposed outside of the expansion chambers, which is associated with the manifold and is operated by the piston arrangement to move between a first position, in which one expansion chamber communicates with the inlet and in which the other expansion chamber communicates with the vent, and a second position, in which one expansion chamber communicates with the vent and in which the other expansion chamber communicates with the inlet. In this manner, the piston arrangement is reciprocated. Regulating means are associated with one of the expansion chambers, for regulating air flow into one expansion chamber or air flow out from one expansion chamber. By such regulations, the piston arrangement and the carriage move relatively more forcefully in one of the opposite directions than the other of the opposite directions. Articles on the article-carrying surface are thus transported in a direction opposite thereto. In this way, articles on the article-carrying surface are incrementally displaced in the direction opposite to the more forceful stroke.

Abstract: An article for presenting dye/pigment images therein comprising a substantially transparent viewing region (20); photode-veloped, printed, deposited or diffused dyes and/or pigments (21) in the viewing region; and a substrate region (22) adjacent to the viewing region. The outer surface (23) of the viewing region is configured in a relief pattern comprising microscopic, smooth, share pyramids (31), cones (48), or ridges (29), to provide a series of at least 3 surface reflections of any light impinging thereon, before the light travels toward the viewer's eyes. The reflectivity at any one surface reflection is less than about 5% of normal inci-dent light, so less than about 0.05% (and preferably not more than 0.02%) of such incident light is returned toward the viewer after 3 reflections, and less after (4). A viewer thus can see the dye/pigment images clearly from any direction and free from no-ticeable reflected light from the outer surface, and without loss of detail or contrast in dark areas.

Abstract: A plurality of ATM networks may be interconnected to allow communication of voice-band signals between them by using one or more PSTNs and a novel interface that converts ATM formatted data packets to a format usable by digital multiplication equipment (DCME). Such an interface thus allows the DCME to advantageously function as a gateway between the ATM network and PSTN by providing for optimum bandwidth usage between the networks. In an illustrative example of the invention, a DCME available from AT & T as the Integrated Access and Cross Connect System ("IACS"), is provided with an ATM-to-DCME interface that converts ATM formatted packets to a regular channelized bitstream usable as an input by the IACS. The interface and the IACS are positioned on both ends of a PSTN to allow for connectivity between the PSTN and a plurality of ATM networks, as well as the required optimization of bandwidth usage. In another illustrative example of the invention, the functionality of the interface is built in to the IACS to convert ATM formatted packets directly into efficient wideband formatted packets for transmission over the PSTN.

Abstract: An opening end face of a frame is closed by a transparent thin film, a vent is formed in the frame, and a filter having a filtration area larger than the sectional area of the vent is mounted to the frame to cover the vent.  The filtration area of the filter an effective area where allows the passage of gas in the filter.  Then, the filter is mounted to the frame so that there is a certain space between the frame and the filter.  In the conventional device, since the filter is directly mounted to the frame without space between the filter and the frame, the filtration area of the filter is substantially the same as the sectional area of the vent.  In case of mounting the filter apart from the frame, however, the filtration area of the filter can be lager than the sectional area of the vent so that the quantity of gas flow is greater than that of the conventional one.  Therefore, its adaptability to the changes in atmospheric pressure and in temperature is also improved.

Title: Spacer-frame bar having integral thermal break
Inventor: PETERSON WALLACE H
IPC: E06B7/22
Filed: 1996-05-17
Granted: 2006-05-30
Abstract: An elongate tubular spacer-frame bar (18) having an integral thermal break for reducing energy flow between glass panes (14) in an insulated glass panel (10) is provided. The spacer-frame bar (18) includes a first and a second side (24, 25), each side having elongated edges (28, 29). Two nonwelded seams (26) run along the elongate dimension of the spacer-frame bar between the corresponding adjacent edges of the first and second sides. At least one continuous insulating member (30), composed of a nonmetallic, low-heat-conductive substance, and being of a length substantially equal to the length of the spacer-frame bar, separates the first and second sides of each seam, forming a thermal break. The present invention effectively eliminates all direct contact between the spacer-frame bars and the glass panes by separating the two halves of the spacer-frame bar along its nonwelded seams with a nonmetallic/nonconductive substance. This separation creates an effective thermal break along the spacer-frame bar that stops conductivity between the glass panes via the spacer-frame bar, thus further reducing the heat loss in insulated glass panels.

Abstract: The system of the invention consists of a central office service unit (COSU) connected to a plurality of switching systems via dedicated telemetry trunks or a common channel signaling network such as the CCS7 network. The switching systems are connected to a plurality of inbound-only TIUs located on the customer premise that are in turn connected to customer devices such as utility meters, appliances, security systems or the like. The TIUs are inbound-only that can originate calls but cannot answer calls initiated by the controlling entity. A controlling entity, such as a utility, is connected to one of the switching systems over a customer line such that the controlling entity can be connected to any TIU hosted by the switching systems. The controlling entity requests that an alerting tone be sent by the COSU to a desired TIU. The COSU, as is known in the art delivers an alert tone through a suppressed ringing connection to the TIU that does not audibly ring the customer's telephone. The TIU does not "answer" this tone by going off hook such that no connection is established and the telemetry call is taken down. While the TIU does not answer the alert tone, the tone alerts the TIU to perform one or more functions such as retrieve data from a utility meter, check the status of an appliance or the like. As an alternative to the alert tone, a digital signal can be transmitted to alert the TIU. After performing the desired function, the TIU is programmed to call the controlling entity and a connection is established between the TIU and the controlling entity. The TIU can then transmit the results of thefunction to the controlling entity and the controlling entity can download further instructions, programs or the like to the TIU.
