Abstract: SURFACE MOUNTING OF DEVICES ON BOTH SIDES OF A CIRCUIT BOARD         Abstract of the Disclosure Surface mounted components or devices on circuit boards can be connected on a first side by reflow soldering and then the circuit board turned over and further devices mounted on the other side and also connected by reflow soldering.  The devices connected on the first side are retained in position by the surface tension of a molten solder pad.  Solder paste is applied to form a hump and then reflowed to form a solder pad, for example about .010 inches thick.  After positioning devices on the board, on the solder pads, they are connected by reflow soldering.  On turning the board over, further surface mounting devices can be positioned and connected, or other forms such as leaded components, can be connected, by reflow soldering, without loss of the first connected devices.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE        A control valve utilizing the conventional dual wafer check valve, which check valve has a pair of semicircular plates pivotally mounted about a pivot rod at the adjacent straight edge surfaces thereof. The plates are mounted by hinge brackets that allow initial translational movement of the pivotted edges of the plates before the rotation about the pivot shaft, so as to provide a clearance between the seal and plates at the pivotted edges.   A control mechanism simultaneously and continuously controls the rotation of the wafer plates so that each plate rotates in opposite directions but the same arcuate distance.          The control mechansim has a pair of levers with one lever pivotted to the rear surface of one of the plates, while their other ends are pivotted together at one end of a linear translational clevis member.  The other end of the clevis member is connected to a pivotal cam follower via a lost-motion connection to convert rotary motion to translational motion.  A handle and drive shaft accessible from outside of the valve body is provided to rotate the cam follower.

Abstract: CLEAVED-COUPLED-CAVITY-LASER DRIVEN SYSTEM FOR MEASURING SMALL SIGNALS            Abstract A laser-driven interferometric signal sensing system has a cleaved-coupled cavity laser with separate stabilization servo loops of different time constants for the modulator and laser sections thereof.  The laser section is biased above lasing threshold, and its stabilization loop is operated at a frequency twice the frequency of laser section bias current modulation.  A laser loop feedback error signal is a function of predetermined, environmental-type, parameter variations in the sensing location and is processed to be a function of the second derivative of interferometer output intensity with respect to laser section current.  That error signal is applied to modify laser section bias current in a direction to zero out the feedback signal.

Abstract: ABSTRACT   A converter for converting a series of digital input bits to an analog output employs a direct current comparator having a magnetic core and primary and secondary ratio windings coupled with the core.  The primary winding is divided into two sections.  A first group of the more significant input bits varies the number of turns of the first primary section which is traversed by a first direct current.  A second group of less significant input bits varies the number of turns of the second primary section traversed by a second direct current.  A direct current is also passed through the secondary winding, this secondary current being varied proportionally with the number of turns of the first primary section traversed by the first primary current.  Modulation-detection windings arranged inside the core (which also acts as a magnetic shield) detect any net ampere-turns unbalance of the primary and secondary currents in the ratio windings.  Detection of such an unbalance further varies the secondary current to tend to bring the unbalance to zero.  The analog output is proportional to the secondary current.  The splitting of the primary winding into two sections enables the converter to handle a larger number of bits, e.g. 20, than would be possible with a prior art type of primary winding, without the number of turns becoming unmanageably large.

Abstract: ABSTRACT OF THE DISCLOSURE:          In a movement compensation predictive encoder, a vector detector (19) is supplied with a moving picture signal and produces a movement vector signal representative of at least one movement vector for each region of each frame.  A picture analyzer (l6) serves as a variation detector for detecting a variation in each region to produce a variation signal when the variation exceeds a predetermined threshold in one of the regions.  The variation signal is used in giving a predetermined value, such as zero, to the above-mentioned at least one movement vector for that one of the regions.  In place of the variation detector, a scene change detector can likewise be used to produce a scene change signal for giving a predetermined value to the movement vectors for a frame for which a scene change is detected.  The scene change detector is preferably operable on a summation for each frame of results of evaluation for movement compensated prediction errors rather than, as in prior art, for diffenances between picture elements of two consecutive frames.

Abstract: A frame to a leaf, for example a panelled door or wicket or similar furniture parts, is configured such that one pair of parallel parts (posts 1, 2) of the frame is configured as angle pieces having an angle v between the arms of the angle pieces of between 100 degrees and 170 degrees, in addition to which one arm 3 of the angle pieces has sufficient length to receive a hinge on its surface 10 and the end face 5 of the other angle arm is intended to receive a panel or board 6, for example grooved, any other pair of parallel parts 7, 8 of the frame being fastened to the posts by the end faces 9 of these parts 7, 8. If such a frame is used, the commonly available doors, where a door is sought which sits at an oblique angle relative to, for example, the sides of a cabinet, for example a corner cabinet or a differential cabinet, can be simply constructed using a small number of standard components. By configuring a post for a panelled door of this kind as an angle piece having at least one arm which is of sufficient length to allow mounting of a hinge, the prospect is offered of being able to construct a frame for a panelled door in a cheap and simple manner, since such an angle piece can be made by mill-cutting or extrusion. <IMAGE>
