Patent CA-2116367-A1 (CA)
Title: Amplifying filter
Inventor: TURUNEN AIMO
IPC: H03H7/01
Filed: 1994-02-24
Abstract: Abstract A filter comprises at least a pair of resonators (RES1,RES2) having  an  amplifier  (AMP)  inductively  or  capacitively coupled between the pair of resonators so that the power of an input signal input at IN passes through the amplifier and output at OUT to provide filtered and amplified output signal. By integrating an amplifier into the filter,this removes  the  need  for  an  amplifier  usually  provided externally to the filter,thus saving space in a product incorporating this filter.This filter could be used as part of  a  duplex  filter  of  a  radio  transceiver,  where,for example,the amplifier could replace one of the stages of a multistage amplifier in the transmission branch of the radio transceiver.

Abstract: ABSTRACT OF THE DISCLOSURE   A protective package system for containing a delivery cartridge for volatile substances such as fragrances, deodorizers, air fresheners and the like, wherein the cartridge includes an active ingredient reservoir with a permeable surface through which substances may move from the reservoir. The packaging system preferably includes a cartridge container having a storage area for receiving the cartridge, and a substantially open top with an outer periphery. A peelable lid is sealingly attached to the outer periphery of the container, and a blotter is attached to at least a portion of the inner surface of the peelable lid and preferably spaced inwardly from the outer edge of the lid so as not to interfere with the sealing attachment of the lid to the container. The blotter is thereby held in face-to-face contact with the permeable surface of the cartridge within the packaging system when the lid is in sealed condition and remains captively attached to the lid upon opening of the packaging system. In a preferred embodiment, the container is further provided with a blotter recess to facilitate preliminary alignment of the blotter with the permeable membrane of a cartridge held therewithin, and to facilitate captive attachment of the blotter to the inner surface of the peelable lid during sealing procedures. In this way, the blotter can be independently placed within an open container after the volatile cartridge has been loaded with its permeable membrane facing outwardly through the open top. Manufacturing procedures are thereby simplified, yet the blotter will be captively attached to the peelable lid to minimize potential for contact with the user upon opening.

Inventor: KOELLE HANS-GEORG
IPC: G01S7/292
Filed: 1994-12-22
Abstract: The invention relates to a digital method of detecting pulses of short duration and an arrangement for implementing the method. A threshold value is generated by means of a statistical procedure which is common in radar engineering, by means of which short pulses to be detected can be differentiated as opposed to long pulses. The method includes sorting a predeterminable number of temporally consecutive signal samples by amplitude and creating a ranking of the signal samples. An associated amplitude value for a predeterminable rank within the ranking is determined and multiplied by a predeterminable weighting factor (k) so that an amplitude threshold value (SW) is generated. All signal samples whose amplitude is greater than the amplitude threshold value (SW) are then marked with a marking signal.

Inventor: PITTNER JOHN R
IPC: B23D36/00
Filed: 1992-06-30
Abstract: An improved method and apparatus for making an accurate cut with a crop shear (12) while the workpiece (11) speed is changing and the shear knife (24, 26) is in an acceleration phase. A shear acceleration factor based on the change in the speed of a workpiece (11) during the acceleration phase for the shear drive (28) is added to a "position trim" value to adjust the speed and position of the shear knife (24, 26) in order to compensate for the change in the workpiece speed during the acceleration of the shear knife (24, 26). The "position trim" value is derived based on the calculated angular velocity reference to the shear drive speed controller (18) at the moment when the velocity of the workpiece (11) changes during the acceleration process, and based on a desired angular velocity of the shear knife in view of the change of workpiece (11) speed.

IPC: H02K/
Filed: 1995-03-09
Abstract: Alternator systems are known in which two pairs of diodes are connected between respective outputs of an alternator and respective outputs of the system, the diodes being connected in opposite senses. In the present invention, a switch is connected in shunt across each of the diodes connected to the zero volts output of the system. The switches are controlled by a control unit, which receives a sample of the signal appearing at the other output. The output voltage of the system is reduced by closing the switches in phase with the output voltage while current is being supplied to the positive output of the system. The output voltage is increased by closing the switches while current is not being supplied to the positive output and opening the switches after current starts to be supplied to the positive output so that energy stored in the alternator is transferred to the system output.

Title: Process for controlling thermodynamic processes in a vortex tube, vortex tube for carrying out the said process and the use thereof
Inventor: TATARINOV ALEKSANDR STEPANOVIT
IPC: F25B9/04
Filed: 1993-02-22
Abstract: A  process  is  proposed  for  controlling thermodynamic processes in a vortex tube by directing a stream of fluid under pressure into a nozzle inlet.          In order to obtain the desired characteristics in the cold and hot streams without altering the construction of the tube, the fluid stream in the nozzle inlet is controlled by altering the parameters of state of the thermodynamic processes taking place in the vortex tube.  Control of the stream in the nozzle inlet is effected by altering the path length of the stream, by splitting the stream into two rotating streams with their own respective path lengths, or by adjusting the speed, flow-rate and pressure of the stream at the entrance to the nozzle inlet.  Controlling the stream in the vortex tube is effected by means of the helix mounted in the cavity of the nozzle inlet in such a way that its position in relation to the inlet stream can be altered, and a baffle situated at the entrance to the inlet aperture.  The invention can be used in industry, for example in the mechining of components, the refrigeration industry and in medicine.

Abstract: The  invention  relates  to  a circuit  arrange-ment (28) for protecting against switching overvoltages power  semiconductor  switches (T1,  T2)  which  can  be switched on and off via their control input (G) and form a pair (2) of arms in a power converter (4). According to the invention, the circuit arrangement (28) comprises a comparator which has a downstream analog amplifier with a limiting characteristic curve and is connected in an electrically conductive fashion on the output side to a control input (G) of the power semiconductor switch (T1, T2) to be protected, an actual voltage (UCE) and a pre-determined desired voltage (U*CE) Of the main terminal (C) of this power semiconductor switch (T1, T2) being present across the comparator. The result is a circuit arrange-ment (28) for protecting against overvoltages, it being possible to dispense with an RCD wiring network for the power semiconductor switches, since very small voltage deviations are detected immediately and the power semi-conductor switch is switched off in a controlled fashion.
