Title: Cross-traffic circuit for PBX exchanges - has cross connection device connected over changeover switch to coupling matrix outputs
IPC: H04Q3/00
Filed: 1968-10-11
Abstract: The cross-traffic circuit, for PBX exchanges, has the cross-connection device (QUe) connected over a changeover switch (ka) to the outputs of the coupling matrix (KE) assigned to these cross connections. Incoming busying of the exchange lines (AUe) causes the changeover switch to become active and connect the appropriate exchange device to the appropriate output of the coupling matrix instead of the cross connection device. The advantage of this interconnection arrangement lies in its reducing the number of coupling matrix outputs needed to handle a given volume of traffic.

Title: Two part symmetrical wheel rim - consists of two stepped portions made by same press tool
IPC: B60B3/02
Filed: 1969-08-18
Abstract: The wheel rim is made from steel pressings (1, 2) joined together by welding. To simplify the process, the two parts have identical stepped profiles so that they can be presed using the same press tool. One of the parts (2) is pressed from a wider piece of metal and has at least on extra step in its profile, while the smaller part has its final stop shortened. This enables the two parts to be fitted over each other, giving a symmetrical rim. The shortened step can be located in a pressed groove in the other part, or can welded by a simple seam weld. The extra step forms the attachment flange (7) for the wheel hub.

Patent JP-2945047-B2 (JP)
IPC: G10L21/04
Filed: 1990-01-19
Granted: 1999-09-06
Abstract: PURPOSE:To take synchronization between pattern display and sound output in a timing when a page is received by providing a page feed time storage section and an utterance speed calculation section and controlling the utterance speed of a voice synthesis section so that sound for one page is uttered within the page feed time. CONSTITUTION:A page feed time storage section 7 stores lapse of time after the reception of a just preceding page. Since the interval of the transmission of pages is nearly constant usually for each program, the time stored in the page feed time storage section 7 is used as a predicted value of the time till a succeeding page is received. An utterance speed calculation section 9 calculates the quantity of voice by one page resulting from the voice conversion before a sound synthesis section 8 makes voice output. The above calculation section 9 divides the quantity of voice by one page by a time stored in the page feed time storage section 7 to calculate the utterance speed. Then the voice synthesis section 8 is controlled so as to synthesize the voice in the calculated utterance speed. Thus, the utterance of the synthesized voice is terminated for a time receiving a succeeding page.

Patent JP-H0262356-B2 (JP)
IPC: B23D79/00
Filed: 1983-02-10
Abstract: To separate combustion within a combustion chamber for deburring or high-temperature, high-pressure article treatment from gas supply valves, the combustion chamber is formed of a dual wall structure, having an outer wall (21) which is telescopically slidable with respect to an inner wall (12). The articles are introduced into the chamber (11) by placing a support plate (14) against the outer wall structure, with the inner wall (12) slightly raised, leaving a gap (23) between the lower edge of the inner wall and the support plate. Gas introduced within the outer wall structure than can pass into the chamber (11) within the inner wall, through said gap. When the requisite volume and pressure of fill gas-typically oxygen and a combustion gas such as hydrogen, methane or the like-is within the chamber, the inner wall (12) is lowered into sealing engagement with the support plate (14), for ignition of the combustible mixture. The inner wall, thus, totally isolates supply ducts and valves from being affected by the explosive pressure.
