Patent EP-0318119-A2 (EP)
Inventor: SPEAKE JOHN DAVID C O PHILIPS
IPC: H03H7/01
Filed: 1988-11-24
Abstract: A bandpass filter circuit arrangement comprises a reactively intercoupled pair of parallel-resonant circuits (1, 2) to one of which a pair of signal input terminals (15, 16) are connected and to the other of which a pair of output terminals (18, 19) are connected. Tuning of the filter is accomplished by varying the capacitive component of each circuit by varying the output of a tuning voltage source (20). In order to compensate for the deviation from the optimum intercoupling which would otherwise occur with change of tuning frequency the capacitive component of each resonant circuit comprises two pairs (5, 7 and 6,8, or 9, 11 and 10, 12) of capacitors in series, each series-connected pair effectively forming a variable capacitive voltage divider to the tap on which the intercoupling means (15) is connected. One capacitor (5, 6, 9 or 10) of each pair is variable, and all these are adjusted at the same rate. The other capacitor (7, 8, 11 or 12) is fixed, and the ratio between the capacitances of the fixed capacitors of each capacitive component are chosen so that the required degree of compensation is obtained. As an alternative the fixed capacitors may be replaced by short circuits and the variable capacitors of each capacitive component may be varied at different rates.

Abstract: Apparatus for applying release oil to a fuser roller pair (10a, 10b) in a xerographic copier comprises an elongate trough (41) containing a supply of oil (42) in the base (44) thereof, and a wick (45) for drawing up the oil from the trough and applying it to a metering roller (47). The metering roller applies the oil to a donor roller (48) which in turn transfers the oil to the heated roller (10a) of the fuser roller pair. The amount of oil on the metering roller (47) is checked by a blade (49) and surplus oil removed by the blade is allowed to fall back towards the trough. In order to promote enhanced distribution of oil along the length of the trough a series of ramps (51a, 51b, 51c) in saw-tooth configuration is provided in or adjacent a side wall of the trough beneath the blade (49) to receive the oil removed from the metering roller before it is returned to the base (44) of the trough. The base of the trough may slope in the opposite direction to the ramps to establish continuous circulation for the oil.

Abstract: The present invention relates to intermediate melting sucrose fatty acid ester compositions that are capable of rapid crystallization from a melted state. The compositions comprise 60% to 97% by weight intermediate melting sucrose fatty acid esters and 3% to 40% hardstock triglycerides or hardstock polyol fatty acid esters. Preferably the average fatty acid chain length of the hardstock material fatty acids is not less than the average fatty acid chain length of the intermediate melting sucrose ester fatty acids. The sucrose fatty acid esters are characterized by their rheology, liquid/solid stability, iodine value, and solids at body temperature. Rapid crystallization of the esters is useful in preventing anal leakage, and it could also translate into a reduction of post-hardening in shortenings and margarines, and into improved high temperature stability and temperature cycling stability as may be encountered during distribution of these products to the end user.

Abstract: A communication system containing: a master station (A), a plurality of slave stations (B1, B2, ... Bn-1, Bn) each for communicating with the above master station (A), a two-way transmission line (101, 102) connecting the above master station (A) and the above plurality of slave stations (B1, B2, ... Bn-1, Bn). Each of the above slave stations (B1, B2, ... Bn-1, Bn) sends a request for a further communication with the above master station (A), to the master station (A) when its own slave station is allowed to communicate with the master station (A) and its own slave station has the above request. The above master station (A) detects the request for a further communication with the above master station (A) in a signal sent from a slave station, and memorizes a slave station from which a request for a further communication with the master station (A) is detected, until an allowance is sent to the slave station from the master station (A) corresponding to the memorizing of the slave station. The master station (A) has a cyclic address pointer (54) which points out an address of a next one of the above slave stations (B1, B2, ... Bn-1, Bn) in a cyclic order when no slave station is memorized in the master station (A). The master station (A) outputs an allowance to communicate with the master station (A): to a slave station which is memorized in the master station (A); or to a slave station the address of which is pointed out by the above cyclic address pointer (54) when no request is memorized in the master station (A).

Abstract: A method and apparatus for positioning tooling and riveting the apparatus including a frame provided with opposed riveting rams (96,86) and clamps (34,36). The first clamp (34) is extended above the work plane (124) established by the outer surface of one workpiece (10) with the lower ram retracted. Next, the frame (26) is moved downwardly until the first clamp touches the work­piece. An encoder (140) measures the amount of first clamp collapse during overtravel of the frame (26) after the first touch is sensed. The frame (26) is now backed off this distance to establish a work line coextensive with the work plane (124). The lower clamp (36) is then raised to clamp the workpieces (10,12) and a drill (88) carried by a sub-frame (66) will now drill aligned apertures through the workpieces (10,12). The sub-frame (66) is indexed to another position to place rams (96,86) in alignment with the apertures. The upper riveting ram (96) is then advanced to its full down position to set an upper cavity and is locked under high pressure. The lower ram (86) then rises under low pressure to a snug-up position. Squeeze forming is now accomplished by   simultaneously controlled motion of the frame down and the lower ram up until an upset complete signal is received. During this operation the upper clamp (34) is in a resilient condition. When the rivet (R) is completely upset, pressure is dumped from the upper clamp (34) and simultaneously the frame (26) is driven to its start position and the lower ram (86) is retracted. As soon as the lower ram (86) reaches its back away position, the upper riveting ram (96) is fully retracted.

The logic elements (36, 38, 39) process a data bit shifted from the preceding stage with the data bit fedback from the output stage in accordance with the polynomial code for input into the succeeding register stage. The structure further includes means (16, 29, 30) for processing the data bits shifted from a predetermined stage of each shift register structure to provide a keystream(44); and means (31, 32) for varying the polynomial code of at least one (10) of the shift register structures by applying to the logic elements (39) an enabling polynomial code signal that varies in accordance with the content of data bits shifted from a predetermined register stage. The polynomial code of one (12) of the shift register structures is not varied in response to the polynomial code signal. The bits that cause the polynomial code signal to be varied are not included in the keystream.
