Title: Process for extending the life of a displacement plating bath
Inventor: KING RANDAL D
IPC: C23C18/31
Filed: 1992-11-18
Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards. During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components.  The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir.  The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment. Preferably, the thiourea is isolated from the anode during electrowinning, so that the acid thiourea solution formed may be used to partially replenish the tin plating solution in the reservoir.  By such periodic removal of the complex, the plating bath is stabilized and its useful life is extended dramatically.

Title: Coin validator
Inventor: MALZARD NORMAN R
IPC: G07D5/08
Filed: 1991-07-04
Abstract: A coin validator (10) has a coin path (26) which passes between one set of detect coils (40, 42). The set a of coils (40, 42) is connected in a detect circuit, and the coils (40, 42) are adapted to be energised with a single pulse. The decay curve (70) of the voltage in the coils (40, 42) is processed to pro-duce a set of three numbers of clock counts defining each coin; which are stored in a microprocessor. pre-programming of the valida-tor ( 10) involves generating sets of numbers for repres-entatives of a coin type to create three ranges of num-bers, within which respec-tive range subsequent coin's set of numbers must fall in order for it to be defined as an example of the coin type. The coin path (26) is arranged at an angle to the vertical, and the base (32) is arranged at an angle to the horizontal such that the angle between one wail (36) and the base (32) is between 90° and 180°, causing coins passing along the coin path (26) to orient themselves such that each of them has point contact on the base (32) and on the one wall (36), thereby occupying a generally similar position with respect to the coils (40, 42).

The hammer head is movable to the rearward with respect to the body and the handle upon impacting a work surface driving one or more pistons rearwardly. Cylinders for the pistons surround a single fastener driver cylinder and piston of smaller surface area than rearward traveling piston or pistons. Hydraulic fluid is forced from the large or multiple piston(s) through a manifold to the rear of the fastener drive piston. Rapid forward movement of the fastener drive piston sets the fastener. Forward movement of the striking head by a return spring or vacuum means opens a chamber for the next fastener to be placed by spring action or hydraulic feed in front of the fastener drive blade, ready for the next fastener placement. The body of the hammer is secured to the handle at an angle A which is between 95° and 116° and the center of gravity of the hammer is located between at handle location ? 10% of the distance from the handle to the normal line through the head in its ready-to-fasten position.        Other embodiments of this invention include features of hydraulic nail or fastener feed, magnetic attraction and repulsion for reset of the striking head, vacuum assist return, direct coupling of the striking head to the drive cylinder and the use of linear bearings for misalignment compensation.

IPC: H05B3/16
Filed: 1993-02-02
Abstract: A heating element for an air flow comprises a channel shaped bracket including a base and side walls at right angles thereto within which is mounted a pair of mica sheets arranged parallel to the base and at right angles to the sides and connected to the sides by ribs longitudinally of the sides with transverse slots within which the sheets slide. Each sheet is wrapped with a heating wire formed into helical coils so that each side of the sheet carries a plurality of parallel helical coil portions with connecting portions wrapped over the edges of the sheet. The sheets are symmetrical and one is inverted relative to the other. Each sheet carries at ends thereof a male and a female connector of the blade and receptacle type so that the blade of one sheet engages into the receptacle of the other sheet. The connectors thus provide mechanical support to hold the sheet in spaced position and in addition provide electrical connection across the sheets so that electrical energy from supply wires is connected in parallel across the wires of the two sheets. The structure is simple to manufacture and provides a structurally rigid arrangement with high wire density leading to reduced wire temperature.

Title: Video decoder
Inventor: VERMEULEN CHRISTOPHE D G
IPC: H04N21/43
Filed: 1993-03-26
Abstract: - 46 - C. VERMEULEN - F. VAN DER PUTTEN     B. VOETEN  1-3-3 ABSTRACT                  VIDEO DECODER A video decoder is proposed which receives packets of video information relating to moving video images from a packet switching network.  In accordance with the invention a lot of hardware overhead is eliminated and much flexibility gained compared to prior art decoders in letting the decoding process. implemented via a decoding means (DEC1, DEC2), run asynchronously with respect to the display process, implemented via a display means (DIS). Moreover, and also in contrast with prior art decoders, the video decoder according to the present invention is not explicitly synchronized to its corresponding encoder by explicitly recovering the latters system clock.  This is realized through buffering actions within a frame store memory (FSM) placed between the decoding means (DEC1, DEC2) and the display means (DIS).  The variable length of such a buffer can be used to control the speed of the display process in order to prevent underflow or overflow of the latter buffer and corresponding image degradation.  The latter is done via a control means (CDN).
