Title: Jam reducing apparatus for coin operated machine
Inventor: DOBBINS BOB M
IPC: G07F5/00
Filed: 1989-04-27
Granted: 1995-04-13
Abstract: Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals. The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid. An entry slot in an entrance blocker, which is an integral part of the lid, is in substantial alignment with the coin insert slot of the front panel of the machine in normal operation. The lid is connected to a torsion spring and is associated with a coin reject lever. The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine. In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing. Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring. This moves the coin entry slot and the blocker slot out of substantial alignment, preventing the insertion of additional foreign matter or another coin. Removal of the foreign matter allows the lid to return to its normal operating position under the force of the spring.

Inventor: NEWKIRK MARC STEVENS
IPC: C22C47/10
Filed: 1990-07-06
Granted: 1999-04-01
Abstract: The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform (4) with molten matrix metal (2) and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or a preform (4), at least at some point during the process, which permits molten matrix metal (2) to spontaneously infiltrate the filler material or preform (4). Moreover, prior to infiltration, the filler material or preform (4) is placed into contact with at least a portion of a second material such that after infiltration of the filler material or preform (4), the infiltrated material is bonded to the second material, thereby forming a macrocomposite body.

Abstract: The separating circuit which utilizes scan line  correlations and frame correlations comprises: a line comb filter (10)  feeding a adaptive vertical line correlator (20), a  delay  circuit  (70), and a frame comb  filter  (50);  a  horizontal  comb  filter  (30) producing the first and the second horizontal correlation data;  a adaptive horizontal line correlator (40) selecting  one  from  the first and the second color  signal  according  to  the  horizontal correlation; a mixer (60) mixing the output of a frame comb filter (50) and an adaptive horizontal line correlator; a  data  selector (80) selecting signal according to the  standard  or  non-standard signal; an output circuit (100) providing the color signal and the luminance signal.

Abstract: 본 발명은 RF수신 시스템에 관한 것으로, 특히 채널 선택시 채널을 스캐닝 하는 동안 기존의 선택 채널을 유지하는 회로 및 방법에 관한 것이다. 
     기존의 선택 채널을 유지하는 회로는 안테나(12)에 접속되어 있으며, 입력되는 선국 데이터에 의해 상기 안테나(12)로부터 수신되는 RF신호중 소망하는 RF신호만을 추출하여 출력하는 튜너(14)와, 상기 안테나(12)에 접속되어 있으며, 입력되는 선국 데이터 의해 입력되는 RF신호중 솜아하는 채널의 RF신호를 검출하고 검출된 RF신호에서 유효신호를 검출하여 출력하는 채널 스캔닝부(24)를 가지고 있다. 
     기존의 선택 채널의 유지는 채널 선국(CH UP/DOWN)신호 입력시 상기 튜너(14)로부터 기존의 선택 채널 선국 데이터를 출력하고, 상기 채널 스캔닝부(24)로부터 유효신호가 출력될 때까지 상기 채널 스캔닝부(24)의 선택 채널을 튜닝하며 유효신호가 입력시 상기 채널 스캔닝부(24)의 채널 선국 데이터를 상기 튜너부(14)로 제공하는 마이크로 프로세서(18)의 제어에 의해 유지된다. 
     이와 같이 채널을 새로이 선택시 튜닝이 완료될 때까지 기존의 채널을 유지함으로써 채널 변경시마다 나타나는 노이즈를 제어할 수 있게 된다.
