Title: Two hand operated machine control station using capacitive proximity switches
Inventor: WHEELER KEITH D
IPC: F16P3/20
Filed: 1992-12-11
Abstract: A monitoring circuit (10) for monitoring the state of the capacitive proximity switches (14, 42) used in a two hand industrial machine control station (13) is disclosed. Each proximity switch (14, 42) has a monitoring circuit (18, 46) for monitoring the length of time that the proximity switch remains activated.

Title: Procedure and apparatus for compensating the slip of an induction machine
Inventor: SIRJOLA JUHANI
IPC: H02P23/08
Filed: 1993-12-01
Abstract: ABSTRACT OF THE DISCLOSURE           The  invention relates to a procedure and  an apparatus for adjusting the speed of an induction machine fed by a frequency converter or an inverter to a value corresponding to a speed reference value  fR.   In the procedure, a frequency signal nm dependent on the speed of the motor  is generated and the  speed reference fR  is corrected by means of a correction signal C proportional to the slip of the motor.  The corrected speed reference value is used as a frequency reference fs for the frequency converter or inverter.   According to the invention, the correction signal C proportional to the slip is generated with  the  aid  of  the  frequency  signal  nm  and  another frequency signal ns' formed from the frequency reference fs of the frequency converter or inverter.   When the motor speed changes, for example, due to a variation in the load, the  frequency reference of the frequency converter  or inverter is corrected accordingly.

Title: Monopulse reply extractor for ssr navigation systems
Inventor: VERBEKE CHARLES E JR
IPC: G01S13/78
Filed: 1992-07-30
Abstract: An SSR reply decoding system for separating pulse codes of a series of closely-spaced or overlapping SSR replies is dis-closed. A delay line (11) is connected to receive pulses representing the leading edge of each SSR reply code pulse. The delay line (11) has a length corresponding to at least two bracket lengths of an SSR  reply. A bracket decoder (12) is connected to respective taps (F1, F2) of the delay line (11) for determining the beginning and end of a first SSR reply. A phantom reply detector (11) is connected to the remaining taps for inhibiting the bracket decoder when two replies are represented by pulses in the delay lines, one of the replies having a pulse space from the pulse of another reply equal to a framing pulse period for an SSR reply. The phantom reply detector (13) therefore inhibits the detection of phantom replies. As a discriminate for determining when pulses having the spacing of a framing period belong to different replies, azimuth data is provided which will permit discrimination of these phantom conditions.

Abstract: Abstract of the Disclosure A method of monitoring, while on board an automotive vehicle, one or more of catalyst performance, engine misfire, and combustion quality, the vehicle having an internal combustion engine equipped with a catalyst for converting noxious emissions of the engine, comprising: (i) exposing at least one pair of EGO sensors to substantially the same emissions either exiting from the engine or from the catalyst, one of the EGO sensors having its electrode highly catalytic, and the other sensor having its electrode low-to-noncatalytic; (ii) comparing the outputs of the sensor electrodes (amplitude, frequency, or phase shift) to determine if there is a sufficient differential to indicate a misfire or poor combustion in the case of the sensors being located downstream of the engine exhaust but upstream of the catalyst, or indicating poor catalyst efficiency in the case of the sensors being placed substantially immediately downstream of the catalyst.  The catalyst may be a three-way catalyst (or an oxidation catalyst).  The sensors may be of the EGO, HEGO, or UEGO types.  Two pairs of sensors may be used, a first pair being placed substantially immediately upstream of the catalyst and the second pair being placed substantially immediately downstream of the catalyst, the pairs of EGO sensors being incorporated into a closed-loop feedback control of the engine fuel control system.

Abstract: A method of determining the best position for an inner member relative to an outer member within a rotary machine requires the inner and outer members to be rotated relative to one another. The spacing between the inner and outer members at at least one location along the length of the rotary machine is detected generally continuously over at least one complete revolution. The detected spacing is then processed to determine the best position for the inner member relative to the outer member. An apparatus for carrying out the method is also disclosed.

Abstract: The present invention has as its object to detect the termination of ink reliably and highly accurately in an ink jet recording apparatus. An ink cartridge 2 has an opening 5 for connection to a recording head 1, and is comprised of a negative pressure generating member containing portion 14 containing a negative pressure generating member 13 and having an atmosphere communicating port 10, and an ink containing portion 16 which is adjacent to the negative pressure generating member containing portion 14 and communicates therewith at the bottom 11 of the ink cartridge. Ink detecting means 3 is provided below the ink containing portion 16. When the detecting means 3 detects a reduction in the remain in the ink containing portion 16, ink remains only in the negative pressure generating member containing portion 14 and the remainder can be substantially estimated. For the remaining ink, the amount of use is calculated by the counting of discharge pulses or the like and is compared, whereby the remain of the ink can be detested accurately and easily.

Title: Impregnation of tissues with aromatic products
Inventor: HARGREAVES NIGEL
IPC: A47K10/16
Filed: 1994-01-20
Abstract: A method of impregnating tissues with an aromatic product comprises packing the tissues in a substantially sealed container together with a quantity of a volatile liquid form of the aromatic product, the volatile liquid being contained on an absorbent base which is separated from the tissues by means of a film which prevents the flow of liquid from the base to the tissues but permits the evaporation of the volatile liquid to liberate the aromatic products for absorption by the tissues. Preferably, the base is located in an envelope formed of the film whereby the film and base together form a sachet. In the case where the container is a cylinder and the tissues take the form of an open-centred roll the sachet is preferably located within the open centre of the roll.

Title: Closure with two position lock ring
Inventor: STURK RON
IPC: B65D45/32
Filed: 1994-10-26
Abstract: An extendable pouring spout closure for liquid containers of the kind that can be fitted to pre-formed circular openings, which have upstanding beaded rims, on such containers, and a cap assembly and locking means for use with that spout. The spout is installed in an inwardly folded, or re-entrant position for storage, and is pulled out to an extended, pouring position. A threaded cap closes the spout when not in use. A pair of bails are moulded integrally with the cap during manufacture, as is an outer plastic locking ring. The bails are attached to the body of the cap by plastic hinges at their ends, and by an inner set of intermittent frangible membranes along their arc. The plastic locking ring is attached to the bails by an outer set of intermittent frangible membranes. The spout portion has a skirt with an annular recess for mating with the bead on the pre-formed rim. The lower edge of the annular recess of the skirt has an inwardly cantilevered lower lip which is stretched outward past the bead during installation. After the skirt of the spout is installed the outer frangible membranes securing the locking ring to the bails of the cap are broken and the locking ring is forced downward over the skirt and rim. The locking ring is stretched slightly to do this, and compresses the lower edge, locking the lip under the bead, and securing the closure to the container.
