Title: Multiple resonator component-mountable filter.
Inventor: MOUTRIE MICHAEL F
IPC: H01P7/04
Filed: 1987-05-27
Abstract: A dielectric block filter (501) which may be mounted on a printed circuit board or other substrate as a single component. The dielectric filter utilizes metallized hole foreshortened resonators (529-535) in the dielectric block (501), which employs capacitive coupling between resonators controlled in part by an electrode strip (553-558) coupled to the conductive material covering the majority of the dielectric block (501) surface. Input and output coupling is accomplished via terminals (505-507) asymmetrically arranged in a mounting bracket (503). Mounting tabs (515-523) on the bracket (503) opposite a recessed area holding the dielectric block secure the filter (501) to the circuit board and provide ground connection for the filter. Two or more filters (501) may be arranged on the circuit board to form a duplexer.

IPC: B23Q11/04

Abstract: A vibrating cutting tool capable of self-amplifying micro-vibrations at the cutter edge generated during machining. The vibrations at the cutter edge are transmitted to vibrators such as steel balls (10, 16, 19) supported on spring members (11, 18), compressing the springs. The springs rebound to push back the vibrators, which hit the cutter directly or through an output shaft (2) so that the vibrations amplified by the springs will be trasmitted back to the cutter edge. With a rotary type cutting tool, if the cutter is overloaded during machining, an output shaft (2) supporting the cutter is disengaged from an input shaft (1) fixed to a live spindle of a machine tool, thus preventing the cutter from being damaged. With an unrotatable type, if the cutter is overloaded, an air pressure detector detects the abnormality of the cutter and causes the machine tool to stop.

Abstract: In processing a video signal reproduced from a track of a magnetic disc (10), if the reproduction video signal of one track out of the frame recorded two tracks is stored in the memory (34), then the control circuit (20) determines whether the memory (34) should be used as a field memory or a frame memory based on the field/frame discriminating signal reproduced from the track which is being reproduced. Therefore, the error can be prevented which occurs when only one track out of the frame recorded two tracks is erased.

Abstract: Conventional isotonic lipid emulsions containing essential  omega -3-fatty acids, e.g. in the form of EPA, can be converted only inadequately in vivo into triunsaturated eicosanoids because they are preferentially consumed in energy metabolism, i.e. oxidised. Combination of  omega -3-fatty acids or their physiologically acceptable esters with triglycerides of medium chain length results in the triglycerides of medium chain length being preferentially oxidised in the body, and the  omega -3-fatty acids being protected from rapid oxidation so that increased amounts of them are available for the formation of triunsaturated eicosanoids. The combination also has a protective effect on the liver. Isotonic lipid emulsions containing  omega -3-fatty acids are used, in particular, for parenteral administration in post-aggression metabolism associated with chronic inflammatory disorders and in neonatology and paediatrics.

Abstract: The knob spindle (15) of a self contained electrically controlled door lock is locked and unlocked by a unidirectional miniature electric motor (51). The motor drives a lock pawl (35) to and from locking position through cyclically operable mechanism including an energy storing spring (38). The mechanism invariably operates through a cycle and, if the pawl (35) is prevented from moving, energy will be stored in the spring (38) to subsequently move the pawl, thereby preventing stalling of the motor and undue drain on the batteries.

IPC: F28F21/06
Filed: 1988-04-07
Abstract: A process for the manufacture of a heat exchanger from a thermoplastic polymer especially a polyamide, is disclosed. The heat exchanger comprises two generally planar panels (11) formed from a composition of the polymer, bonded together to form a labyrinth of fluid passages (16,16A,16B) between the panels (11) that extend between inlet and outlet means (17,18). The labyrinth occupies a substantial proportion of the area of the panels. The process comprises coating a first panel with a first coating in a pattern corresponding to the fluid passages of the labyrinth, and coating the second panel with a second coating composition in at least those areas where a bond is to be formed with the first panel. The coating compositions are selected so that under the influence of heat, the second coating composition will bond to the polymer composition but not to the first coating; thus the first coating acts as a resist coating. The coated panels are brought into contact and heated so as to effect bonding, and then the passages are expanded e.g. by applying a pressure of a gas to the fluid passages between the panels. The expanded fluid passages should be heat set so as to reduce distortion during use of the resultant heat exchanger. Depending on the polyamide selected for fabrication of the heat exchanger, the heat exchangers may be used in a variety of end uses, including in automobiles.

Abstract: A device for coupling the cutting platform to a combine harvester includes a rotary hook (8) which can be rota­ted by means of a control lever (10) between a rest position and an operative position in which it engages a catch element carried by the cutting platform. The book (B) is held in the operative position by a locking member (23) which is resiliently biassed towards the locked position and can be moved away from this posi­tion by means of a cam member (16) which is interposed in the connection between the control lever (10) and the hook (8). The connection is such that rotation of the control lever (10) towards the locked position causes a corresponding rotation of the cam member (16) and the hook (8) whilst rotation of the control lever (10) towards the unlocked position is transmitted to the hook (8) by the cam member (16) only after the cam member (16 ) has completed a first section of its travel, which is necessary to move the locking member (23) away from the locked position. Preferably, two hooks (8) are provided which are operable by means of a pair of control levers (10) situated on the same side of the combine harvester.

Abstract: A remote control transmitter contains on a circuit board (3), which is rigidly connected to the transmitter housing (1) of the remote control transmitter, a positional-deviation switch configuration (17), which in the event of an angular deviation of the circuit board (3) and thus of the remote control transmitter beyond a particular trigger angle (ao) from a particular given or instantaneously determined reference operating position generates an output signal designating the direction of the positional deviation. In a signal converter (5) of the remote control transmitter, this direction-dependent output signal is converted as a control command into a transmission signal, and emitted via a transmitter element (4) of the remote control transmitter to a remotely controlled electrical appliance. By means of swivel movements of the remote control transmitter from the wrist of the user operating the remote control transmitter, different control commands to the remotely controlled appliance are generated in this way in the remote control transmitter.
