Patent GB-905595-A (GB)
Abstract: 905,595. Band-pass filters; piezo-electric resonators. CLEVITE CORPORATION. March 16, 1960 [March 24, 1959], No. 9237/60. Class 40 (8). A band-pass filter comprises a number of four-terminal electromechanical resonant devices connected in cascade with a coupling capacitor between at least two of the devices. As shown, the resonators 12a to 12d consist of axially-polarized discs of a ferro-electric ceramic, e.g. lead zirconate titanate containing small quantities of strontium and chromium. The discs are provided on one face with a central electrode 14 and an annular electrode 16, and on the opposite face with a single counter-electrode 18 or two electrodes similar to those on the first face. The discs are dimensioned to resonate in a radial mode at the same frequency and the filter is designed to operate at the first overtone of the fundamental radial disc frequency. One of the electrodes (either central or annular) of each disc is connected to the corresponding electrode on the next succeeding disc, all the counter-electrodes 18 being connected to a common conductor 22. The input may be connected to a central electrode 14 which presents a high impedance or to an annular electrode which presents a low impedance. Each resonator behaves as an impedance transformer and the whole circuit effects an impedance transformation if the number of sections is odd. Coupling capacitors C 1 , C 2 , C 3  may be alternately shunt and series-connected (as shown) or may be all connected in shunt or all in series. An analysis of the circuit (given in the Specification) shows that the band-width of the filter may be varied about a constant centre frequency by changing the ratio of the input and output impedances of the sections whilst maintaining the product of the impedances equal. Thus, by increasing the value of C 1  and C 3  (which are equal) and decreasing the value of C 2 , the bandwidth may be decreased. To effect this, the coupling capacitors are replaced by banks of capacitors associated with ganged switches (Fig. 9, not shown). Specifications 818,710, 843,919, 843,920, 848,019 and 848,039 are referred to.

Title: False twist texturing
Inventor: FOSTER PETER WILLIAM
IPC: D02G1/20
Filed: 1993-02-05
Abstract: A method of controlling the manufacture of false twist textured yarn is characterised by adjusting non-isothermally in a closed loop the heat flux taken up by the yarn in tension to produce a desired state of texture and hence a specific yarn dyeability. Adjustment can be achieved by feeding back the output of a direct-acting yarn texture sensor to control at least one of yarn heater heat supply, yarn twist speed and yarn feed speed. The sensor is arranged to sense at least one of textured yarn speed (YS), yarn temperature, yarn bulk and yarn tension. A very compact texturing line is possible when the control method is applied comprising a heater with main (H1) and auxiliary (H2) heat inputs, a cooler (TC) and twister (TW). Control inputs may be applied to the drives of yarn feed means (FD, SD, TD, YW) and to the twister drive (TW) as well as to the auxiliary heater input (H2). A tensioner (YT) downstream of the yarn speed sensor (YS) relaxes the tension at the latter. A similar result may be achieved by braking the drum of the sensor. <IMAGE>

Title: Method of detecting contact of computer input mouse with suface.
Inventor: YOSHIZAWA KENICHI
IPC: G06F3/038
Filed: 1993-07-23
Abstract: The method enables a mouse to continue to input data when lifted from its usual operating surface without the need for a device which detects contact with the surface. When the mouse 1 is being moved on a surface, its x and y movement data are sent to a reception buffer 2 and thence to a system processor 5 which causes the cursor to move on the display 6. The movement data are also sent to a processor 4 which processes the data using data, from a characteristics holding portion 3, which depend on the dynamic characteristics of the particular type of mouse being used so as to estimate from the manner in which the movement data reaches zero whether the mouse has been lifted from the surface or has been stopped by the users hand. The method is applicable to various kinds of mouse, eg optical or mechanical. <IMAGE>

Title: Register scoreboarding in a pipelined microprocessor
Inventor: ARNOLD JAMES M
IPC: G06F9/32
Filed: 1993-09-16
Abstract: A resource scoreboarding mechanism (6) allows overlapped instruction execution in a pipelined microprocessor by extending the capability of scoreboard bits (21) in a register file to all multiple cycle operations. If any instruction being issued is lacking any needed resource then it is stopped and reissued in the next cycle. Resources are checked concurrently with the issuing and beginning of the instructions. Register Scoreboarding sets the destination register or registers busy once the instruction operands pass the resource check. When the result returns - whether 1 or many cycles later - the resultant register gets cleared, marked as not busy and free to use. Each multi-cycle functional unit maintains a busy signal that is used to delay a new instruction that needs to use the busy unit. <IMAGE>
