Title: Coin acceptor or rejector
Inventor: DAVIES RONALD C
IPC: G07D5/08
Filed: 1981-10-27
Granted: 1986-04-12
Abstract: A coin acceptor or rejector includes a coin chute having a coin acceptance portion, a coin rejection portion, and a flapper controlling the direction of the coin movement to one or the other of these portions. A sensing coil surrounds the coin-receiving end of the chute so as to have its Q substantially decreased by a coin and by the magnetic hysterisis of the coin whereby the effective resistance of an oscillator including the coil is reduced.

Abstract: An all season type tire tread (11) comprises a plurality of laterally extending grooves (36) having curved portions adjacent to each lateral edge (TE1, TE2) of the tread, said curved portions extending in circumferentially opposite directions. Axially spaced zig-zag shaped grooves (4-8) extend circumferentially around the tread, every fourth leg of a zig-zag groove being coincident with a portion of a laterally extending groove (36). Two legs adjacent to said fourth leg connect the laterally extending grooves to short semi-blind grooves (19) having their central portion coincident with every other fourth leg of the zig-zag shaped groove. The various grooves cooperate to define block elements (20-25), arranged in circumferential rows (30-35) and having the shape of an "S" or of a "Z". The blocks can include a plurality of slots (50-53) and humps (29) can be located between neighboring blocks. <IMAGE>

Abstract: 본 발명은 황산알루미늄과 란타늄 화합물을 혼합하고, 그 혼합물을 가열한 다음 열분해시켜 생산한 내열성 전이 알루미나 및 이의 생산 방법에 관한 것이다. 내열성 전이 알루미나는 BET 비표면적이 높고, 심지어 1000℃ 이상의 온도하에서도 BET 비표면적이 거의 감소하지 않은 탁월한 내열성을 가지며, 비표면적이 낮은 다른 촉매 지지체를 피복시켰을 때에도 공극률이 높고, 생산 비용이 저렴하다.

Abstract: The device has a structure that defines a plane folded in the center of panel (1) and in that the horizontal axis is defined as X and the vertical axis is Y, an arbitrary point on the fluorescent screen (2') formed when the fluorescent screen (2) is projected on the folded plain is defined as f, a perpendicular length between f and X is defined as E, hence the fluorescent screen formed on the inner part of the panel increases or decreases according to the perpendicular length E moves from the center of panel to the edge, and the fluorescent screen (2') on the folded plane is projected to the inner of panel.
