IPC: H02H7/12
Filed: 1981-05-22
Abstract: An integrated regulating module for current and voltage regulation is employed in a circuit arrangement for limiting and regulating the collector current of a control transistor of a switching network component. The module comprises a pulse width modulator, a reference voltage source, an operational amplifier for current regulation, an operational amplifier for voltage regulation, a disconnect device and two dual outputs. The control transistor is connected in series with a current transformer whose secondary is connected in parallel to a series arrangement of a diode and a variable resistor, and a half-wave rectifier circuit. Two bistable switches are provided such that one input of the first bistable switch is connected to the reference voltage source of the regulating module and the other input is connected to the output of the regulating module. The output of the first bistable switch is connected to one input of the current regulating operational amplifier and the other input is connected to a tap of voltage divider which is connected across the output of the half-wave rectifier. One input of the second bistable switch is connected to the tap of the variable resistor, its other input is connected to a further reference voltage and its output is connected to drive the disconnect device of the integrated regulating module.

Abstract: An electro-acoustic transducer of novel structure suitable for automatic assembly is made by arranging with its wall upwards a generally cup-shaped rear cover 20 having a cylindrical wall out-turned at its upper end and extending from the rim of a base divided along a chord 60 into a major segment 61 for receiving an electromagnetic driving unit 30, 34 and a terminal receiving minor segment 62 at a higher vertical level than the major segment 61. The major segment 61 has on its inner face fixing lands 40, 41 disposed symmetrically with respect to a diameter normal to said chord 60 offset away from the minor segment 62 and extending inwards from the side wall. Each fixing land 40, 41 is formed to define a fixing location 64 and having on its face presented to the minor segment an upstanding locator wall 66; 
<??>A yoke and coil sub-assembly lowered into the rear cover is defined by a cruciform yoke plate of magnetisable material having a magnet 50 at its centre with one pair of upturned opposite arms directed along the diameter normal to said chord 60 to said pair of arms defining pole pieces and carrying coils 30, 31 and with the other pair of upturned opposite arms 32, 33 parallel to the said chord 60 and formed with outturned fixing ears 52 that settle directly on said lands 40, 41 behind said locator walls 66 with through-holes 52 therein aligning with said fixing locations 64 of said lands; 
<??>Onto the yoke and coil sub-assembly is placed downwardly an armature 34 formed with depending bearing means that settle on the magnet 50 and permit the armature 34 to rock thereon and a pair of torsion arms extending towards the lands 40, 41 and terminating in fixing ears 35, 36 that settle behind the locator wall 66 on the fixing ears 51 of the coil sub-assembly with through-holes 52 aligning with said fixing locations 64 of said lands. The armature has secured thereto an upstanding connecting rod 34a; 
<??>The armature 34 is mechanically fixed from above the rear cover in tight contact with the yoke plate and the yoke plate is fixed in tight contact with the lands 40, 41 so that the armature is supported for vibration in said rear cover 20. Connector terminals 45 are introduced through said minor segment 62 and electrically connected to the coils. A dished diaphragm 23 is placed downwards onto the rear cover so that its rim 25 settles on the outturned end of the cylindrical wall and the connecting rod 34a projects through a throughhole in said diaphragm. Then the connecting rod 34a is adhered to the diaphragm 23; and a front cover 10 is assembled to the rear cover 20.

IPC: G08B13/18
Filed: 1988-12-23
Abstract: Modern infrared radiation detectors have a coverage angle of up to 180 DEG . Such a wide coverage angle is not always required, since interfering sources which are located outside the area under surveillance are occasionally detected in its peripheral area. The new radiation detector is intended to enable simple restriction of the coverage angle and can be adapted, if necessary, to changing conditions. 
<??>According to the invention, a detector casing (1) is provided with a frame (5), in which a guide channel (7) is formed which is suitable for the accommodation of a closable covering element (6). The covering element (6) can be pushed in front of an optical system (3) so that the coverage angle ( alpha 1) of the latter is reduced to a coverage angle ( alpha 2). 
<??>The invention is preferably employed in passive infrared detectors which are used for area surveillance.

An inward flow rotary drum filter comprises an application box 14 engaging the filter surface and used to apply yeast suspension for filtering, and optionally a filter aid such as starch or diatomaceous earth, the box floor comprising a knife 15 which scrapes solids from the drum. In Fig. 3, the drum 1 rotates anticlockwise, and initially filter aid suspension prepared in mixer (9, 10) (Figs. 1, 2, not shown) is pumped to box 14 while knife 15 is moved slowly outwards by hand or power to build up a smooth layer on the drum, excess being scraped off by kniife 15 and falling back into the mixer. When 20 to 30 mm of filter aid have been deposited, yeast suspension is delivered to box 14 while knife 15 moves inwards, scraping off a mixture of yeast and filter aid. When filter aid is not used, knife 15 is fixed A box (20) above box 14 delivers sprays of wash water on to the yeast. The drum comprises a draining net 3 below the filter medium and hollow spokes 2 deliver filtrate to the hollow shaft. The drum surface may be divided into annular sections on which separate vacuum pumps (5) operate, sections out of use being cut off by valves or plates (8) in the drum shaft. The location of boxes 14, (20) above the horizontal plane of symmetry of the drum ensures that liquid flowing down spokes 2 assists in forming the vacuum.

Title: Upward deflecting support disk for electrochemical cell seal
Inventor: PALMA CHRISTOPHER L DE
IPC: H01M2/12
Filed: 1995-08-11
Abstract: A metal support disk for an electrochemical cell seal exerts a resilient outward radial force against the seal to maintain seal integrity over a wide range of operating temperature and, at the same time, exerts an upward force against the bottom of the metal end cap terminal of the cell to assure electrical contact between the anode inside the cell and the terminal. The disk includes a central, circular platform connected to an outer, sealing edge sealing flange by an annular flexure means which permits radially inward and outward movement of the sealing edge when the end of the cell is radially crimped during the sealing process. The crimping also moves the central portion of the disk up which results in the upward force being exerted against the end terminal. The flexure means is a sequential series of three annular, curved fibs with the first and third curved downward and the second curved upward. A ring depending radially outward and at an upward angie from the first fib connects the first fib to the second fib and helps to prevent plastic deformation of the disk during sealing.

Title: Improvements in or relating to smart antenna arrays
Inventor: GUO YINGJIE JAY
IPC: H01Q21/20
Filed: 2001-06-12
Granted: 2005-06-01
Abstract: The present invention relates to a beamforming method for smart antenna arrays, and in particular relates to a beamforming method for smart two-dimensional antennas. Smart antennas employ arrays of low gain antennas connected to a combining/beamforming network. Smart antennas can provide enhanced coverage through range extension, hole filling and improved building penetration. By improving transmission and reception at the base station, the tolerable path losses can be increased whereby the range of the base station can be improved. A first aspect of the invention thus provides a method of generating low sidelobe beampatterns for 2-dimensional arrays. A further aspect addresses the feedback signalling techniques which are presently being considered by standard bodies for four antennas in large arrays. The invention is suitable for CDMA wireless cellular systems, as presently determined for third generation cellular wireless networks, and other wireless systems such as TDMA systems and wireless LANs. <IMAGE>   <IMAGE>
