Abstract: ABSTRACT OF INVENTION          This invention relates to apparatus for use in connection with material such as fluxed, woven, copper ribbon, sometimes called "desoldering braid" to capture and remove unwanted, molten solder from electronic components.  A preferred embodiment comprises a hand-held desoldering braid gun having a handle in which a supply of desoldering braid may be stored, a finger trigger actuated pincer-type cutter positioned in the mouth of the "barrel" of the gun, a guide conduit for forming a path for desoldering braid coming from the handle through the cutter, and a thumb-actuated drive mechanism for moving desoldering braid to and fro past the cutters.   Another embodiment includes a handle to receive a pre-packaged cassette of desoldering braid.  Using embodiments of this invention, a length of desoldering braid may be introduced to unwanted solder which has been rendered molten to a liquid state, to capture and remove it from its site, follow-ing which the cutter may be actuated to sever off the solder laden length of braid when the solder has hardened.  By this means, such operations may be performed with one hand, freeing the other to do collateral operations, such as holding a solder heating source.

Abstract: CERIUM OXYCOMPOUND, STABLE ANODE FOR MOLTEN SALT         ELECTROWINNING AND METHOD OF PRODUCTION                       ABSTRACT      The morphology of a coating of an oxyfluoride of cerium on a conductive substrate is improved by addition of tantalum, niobium and/or other pentavalent metals. Whereas a cerium oxurluoride coating shows cracks which may extend throughout the entire thickness of the coating, thus exposing finite portions of the substrate to corrosive attack, the pentavalent-doped coating has a substantially impervious structure. In addition to improvement of the coating morphology, the electrical conductivity is increased. The pentavalent-doped cerium oxyfluoride can be produced by electrodeposition or sintering. Coatings, substrates or bodies of this material may be employed as non-consumable anodes in molten aluminum electrowinning cells, as chemical sensors, or for corrosion protection and other applications.

Abstract: ABSTRACT: Apparatus for reproducing a PCM-modulated signal, comprising a muting circuit.           An apparatus for reproducing a pulse-code-modulated signal comprises error-correction means (3) for correcting errors in one or more of the data words forming the pcm signal. When the error-correction means are no longer capable of correcting errors in the pcm signal, they produce error flags on an output (7), which error flags are applied to a control unit (9). From these error flags the control unit (9) derives a control signal which is applied to a muting unit (6) for switching on the muting unit.          A method is described by means of which the control unit derives the control signal from the error flags applied to its input (8). A first auxiliary signal (S1) is generated if (at least) n1 error flags are detected within a first time interval (T1). Subsequently, an i-th auxiliary signal (Si) is generated if (at least) ni error flags are detected within an i-th time interval (Ti) which occurs after the instant at which the (i-1)-th auxiliary signal appears. The value of   ranges from 2 to N inclusive. Subsequently, a control-signal generator generates the control signal during a time interval Tm which occurs after the instant at which the N-th auxiliary signal is received (Fig.2). A number of examples of the control unit are described (Fig.4).

Title: Printing mechanism
Inventor: VOLK HEINRICH
IPC: B41K1/10
Filed: 1987-10-07
Granted: 1991-01-15
Abstract: ABSTRACT     A printing mechanism is described comprising a plurality of type carriers which on their outer peripheral face carry in one region printing types and in another region indicator types.  The printing types can be brought by turning the type carriers into a printing position.  A setting means including an actuating knob can be brought into a drive connection with each of the type carriers for rotation thereof.   Stop means limit the turning travel of the type carriers.   With a detent moment governed by their  spring hardness  resilient  detent elements hold the actuating knob against a rotation relatively to the type carrier in drive connection with the setting means, the detent moment being greater than the torque necessary to rotate the type carriers.   A setting member for influencing the spring hardness of the detent elements can be brought into engagement with said detent elements.

Title: Interrupted liquid phase epitaxy process
Inventor: KNIGHT DOUGLAS G
IPC: C30B19/08
Filed: 1988-03-30
Granted: 1991-12-17
Abstract: Abstract An interrupted liquid phase epitaxy process for producing distributed feedback laser wafers involves epitaxial growth at a first temperature range followed by epitaxial growth at a second higher temperature range.  A prior art liquid phase epitaxy process involves a low temperature soak at a temperature of approximately 615 degrees Centigrade followed by ramped cooling and epitaxial growth of a guiding layer, active layer and confining layer at a temperature of approximately 595 degrees Centigrade.  The interrupted liquid phase epitaxy process involves epitaxial growth of a guiding layer in a manner similar to the prior art process, but growth of the guiding layer is followed by a high temperature soak at a temperature of approximately 645 degrees Centigrade.  Ramped cooling follows, with epitaxial growth of the active layer and confining layer taking place at a temperature of approximately 628 degrees Centigrade.  Epitaxial growth at the higher temperature reduces difficulties with spinodal decomposition and allows improved control over the amount of phosphorus used in the process.

Abstract: AUTOMATIC CIRCUIT LAYOUT ROUTER   ABSTRACT OF THE DISCLOSURE A method for operating a digital computer to globally route interconnects between terminals of a gate array.  A first terminal closest to an average position  of  terminals  to  be  interconnected  is identified.  A second terminal closest to the first terminal is then identified, and a first path between the first and second terminals is established along possible paths.  An edge of the first path is set as a routing path if predetermined conditions are met. A closest remaining terminal to an established path is next identified, and a shortest path between the closest terminal and the established path to which it was closest  is established.   Edges of  the shortest path  and/or  the  established  path  to which  it  was closest are set as routing paths,  if predetermined conditions  are  met.   The  above  steps   are  then repeated  for  remaining  terminals  to  be  inter-connected.   Any  possible  paths  within  established paths with no set edges can then be set as routing paths.
