Abstract: An antenna for a portable radio apparatus has a first antenna construction connected to the casing of the apparatus and a second antenna construction affixed to a base plate or earth plate which is incorporated in the casing.  The first antenna construction has a movable joint which allows the first antenna construction to move between a first position where it is regarded as forming a part of the contour of the casing and a second position where it is protruded from the contour and regarded as being located in free space.  The second antenna construction corrects the matching state of the first antenna construction such that adequate antenna radiation characteristics are set up in the first position.  Optimal antenna characteristics are, therefore, achievable when the first antenna construction is in any one of the first and second positions.

Abstract: In a transmitter in the present invention, an input signal is input to a QMF (QUADRATURE MIRROR FILTER) bank 102 where the input signal is divided to a plurality of frequency bands to form corresponding band signals.  A distributed bit calculating unit 109 calculates respective bit rates with which the corresponding band signals are encoded on the respective power values of the band signals.  Quantizers 104-1, 104-2, ..., 104-n encode the respective band signals at the corresponding bit rates and input the resulting correspond-ing band codes to a cellulating unit 111 which incorporates the respective band codes into a cell as an information unit and sends the cell.  In a receiver, a cell is decomposed to obtain the respective band codes, which are then dequantized to form the corresponding band signals. These band signals are synthesized to form a signal for the entire band, and the signal for the entire band is output as a decoded sig-nal.

Abstract: A method for analyzing seismic shear wave data, using a layer stripping technique, to determine fault plane stress build-up is disclosed.  Polarization directions of shear wave data, from either a vertical seismic profile or from surface reflection data, are analyzed, and time lags between fast and slow split shear wave are determined.  Natural polarization directions of and time lags between the split shear waves in an upper layer are determined above the shallowest depth where data cues suggest polarization changes take place.  Source and receiver axes of the data below the depth of polarization changes are rotated by an azimuth angle, to bring the axes into proper alignment.  A static time shift is then applied to eliminate the time lag in the upper layer above the depth where polarization changes were indicated.  Shear wave polarization azimuth angles, and time lags between the shear waves are determined for the depth of investigation, and are compared to the strike of a nearby fault.  The procedure is repeated at a later time to evaluate any changes in the azimuth angles or time lags.

Patent CA-2046520-A1 (CA)
Title: Cardiac Pacemaker with Automatic A-V Programming for Optimization of Left Heart A-V Interval
Inventor: CHIRIFE RAUL
IPC: A61N1/368
Filed: 1991-07-09
Abstract: A dual-chamber AV sequential pacemaker with the capability of automatically adjusting right heart AV interval to optimize left heart AV interval by compensating for pacing-induced inter-atrial and inter-ventricular conduction delays. Depending on the pacing and sensing action, as determined by the patient's native rate, the predetermined threshold rate and intrinsic AV interval, the pacemaker selects the AV interval. Right heart AV interval is adjusted to compensate for the heart's inter-atrial and inter-ventricular delays. Threshold values are previously estimated, using mean values measured using non-invasive techniques. The pacemaker has a dual phase operating mechanism consisting of an analysis phase followed by a pacing phase. The P wave rate is sensed and compared to a predetermined base rate. If the sensed P wave rate is above the baseline, atrial depolarizations will be sensed by the pacemaker and small number (default = 4) of consecutive native AV intervals will be averaged. If this average is less than a predetermined threshold value, the system will continue in the demand mode, sensing P and R waves. If the average is greater than said value, then the ventricle is paced for n number of times the analysis phase (default = 100 cycles), each followed by a short AV delay (Default = 50 ms) that is intended to compensate for the delay introduced in the onset of left ventricular depolarization after pacing the right ventricular apex. When P wave rate is below the predetermined rate, atrial pacing will occur. During the initial analysis phase, the pacemaker AV interval may be extended to a higher value, say 250 ms, to allow measurement of the native AV interval. At least four AV intervals will be averaged to compensate for possible Wenckebach phenomenon. If averaged AV is greater than, say 220 ms, sequential pacing with AV of 160 ms will take place for 100 cardiac cycles. If averaged native AV intervals are less than 220 ms, atrial pacing with ventricular sensing will be continued with the AV interval set at 250 ms for the next 100 cycles. At the end of either 100 cycle period, another 4-beat analyzing phase is started. Both pacemaker phases (analysis and pacing) are programmable. The 4/100 cycle sequence allows rapid pacing mode corrections under situations such as intermittent block due to exercise or other causes. <IMAGE>

Title: Arrangement for moving and positioning finished concrete parts
Inventor: SUCKFULL GERHARD
IPC: E04G21/16
Filed: 1991-07-25
Abstract: ABSTRACT      The invention deals with an arrangement for moving and positioning finished concrete parts designed as frame members, stacked upon each other and forming the outer walls of a space, for instance a burial chamber.  The invention intends to solve the task of lowering the costs arising in the course of installation of such finished concrete parts above all by reducing the personnel required, however also by avoiding the attachment of entirely or partially lost coupling means, also of increasing the safety when performing these measures and to do away with the use of human labor.          This is achieved in that the arrangement comprises a skeleton frame lowerable into the frame member, at the bottom side of which skeleton frame sit at least two pivot levers with a pivot drive with grips below the frame member, with the pivot drive being operatable by a hoisting mechanism which is detachably coupled with the arrangement.

Title: Storage and transport device for plates
Inventor: SCHMIDMEISTER GERHARD
IPC: B65G1/14
Filed: 1990-02-02
Abstract: ABSTRACT OF THE DISCLOSURE          The object of the invention is a device for storing and transporting painted plates, e.g. doors, by means of individual frames known as "door bearers".  In the present state of the art, the horizontally arranged doors are stacked by laying frames releasably attached to teach end of the door one on top of another.  The drawback of this is the necessity for a handler to hold the stack to prevent it from slipping during transport.  The aim of the invention is therefore to provide a transport device using one handler only while preventing damage to the transported plates.  To achieve this aim use is made of a tubular chassis (10) with rectangular basic frames (14) which may be telescopic in two mutually perpendicular horizontal directions, the corners of which are fitted with vertical posts (22) each pair of which bears possibly telescopic cross-members (26) parallel to transverse shanks (16) on which sit two vertical bars (12) to clamp a horizontal stack of vertically upright frames (36).  The advantage of this system is the force-locking and laterally also shape-locking interconnection of all the frames together and to the chassis which, at least when fitted on the transport vehicle, requires only the driver and not a load handler as well.
