Title: Control system for correcting phase and amplitude
IPC: G01S3/14
Filed: 1956-03-29
Abstract: 839,364. Frequency, attenuation, phase shift measurement. STANDARD TELEPHONES & CABLES Ltd. March 29, 1956 [April 4, 1955], No. 9940/56. Class 37. [Also in Group XL (c)] Two waves are brought into close phase and amplitude agreement by taking their vector difference and resolving it by beating it in synchronous detectors with phase quadrature or other reference waves derived from the vector sum so that two outputs are obtained which simultaneously adjust the phase and amplitude in the path of the waves, until the vector difference is reduced to zero. The system may be applied to maintain equality of phase and amplitude between a reference source 4 and its output from a filter 5, both producing sum and difference vectors in a control circuit 8, the sum vector and a wave in phase quadrature with it derived through a 90-degree phase shifter, being then taken as reference waves and beat with the difference vector in synchronous detectors in the control circuit 8, to derive two outputs which through amplifiers and servomotors retroactively control amplitude and phase adjusters 2, 3 in the path between the reference source 4 and filter 5, until phase and amplitude equality of the outputs from the source 4 and filter 5 is again restored, the restoring voltages and hence transfer characteristics of the filter 5 being indicated on meters 34, 35. Alternatively the two beat outputs may be used to balance automatically opposite arms of a Schering bridge having a resistor and a capacitor in series and in shunt respectively, the controls operating on a capacitor and a resistor in each arm. Specifications 641,809, 763,040 and 838,788 are referred to.

Title: Process for production of prestressed ceramic products, composed ceramic selfcarrying product and gun barrel?
Inventor: NEWKIRK MARC
IPC: C04B35/65
Filed: 1987-09-15
Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.

Patent ID-15986-A (ID)
Inventor: ROLAND MOLLER
IPC: B65H18/26
Filed: 1997-02-27
Abstract: The system is for winding up a strip of paper on a roll (9). When a roll is full, another roll spindle is spun up to speed on an arrangement (7) with a belt (7.3) stretched over two rollers (7.1,7.2). The roll core is then dropped or positively moved down onto the paper web just before it joins the nearly full roll. The paper web is then cut before it joins the full roll, but after the empty roll core. An air blast nozzle blows the paper strip towards the empty roll core, which then catches the loose end of the paper strip and proceeds to roll it up. The support for the full roll is then dropped away and the roll is then removed and the new roll then moves onto the support.

Title: Parallel optical transmitter and receiver
Inventor: TSUMURA HIDESHI
IPC: H04B10/516
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a parallel optical transmitter which compensates the skews caused when plural data are optically transmitted in parallel to each other and can prevent incorrect identification of data by delaying the data signals in response to the phase difference between the data and clock signals. SOLUTION: This parallel optical transmitter has a parallel link 3 which converts the data signals sent from the LSI 1 and 2 that generate plural data and clock signals into the optical signals and transmits these optical signals in parallel to each other via an optical fiber F. A phase comparison circuit 33 compares the phase of the data signal sent from a variable delay circuit 32 with the phase of the clock signal sent from the LSI 2 and feeds a delay time control signal accordant with the phase shift between the data and clock signals back to the circuit 32. The circuit 32 holds the data signals for a time accordant with the delay time control signal sent from the circuit 33 and then outputs them. As a result, the variations of phases can be minimized among the data signals.
