Abstract: A key operated diaphragm type switch comprising a printed circuit board base having conductors thereon, a flexible sheet of non-conductive material supported in taut condition over the base and having an opening therein aligned with adjacent terminal portions of certain of the conductors, and a layer of unwoven matted metal fibers on the order of .10 in. thick overlying the sheet. Upon depression of the key, the underlying portion of the metal fiber layer and the flexible sheet are pressed toward the base. The portion of the metal fiber layer underlying the key is deformed through the opening in the flexible sheet and into bridging contact with the conductors to close the switch.

Abstract: A checkwriter having differentially settable printing sectors for printing amounts on checks and for subtracting such amounts from an accumulator which registers the balance in s user''s bank account. The sectors are also used to add amounts in the accumulator representing deposits in the user''s bank account. The sectors are manually advanced to different amount representing positions from home positions wherein they locate special symbols to be printed in lieu of amounts. After printing, the sectors are returned towards their home positions and during this movement they digitize the accumulator. Overthrow preventing means momentarily arrest the sectors and accumulator at zero registration of the sectors. The accumulator is then demeshed and the sectors are further returned to home positions. Intermeshing check locating members are provided to adjust a check relative to the printing line.

Abstract translation: 具有差异化设置的打印扇区的检查器，用于打印支票上的金额，并从用户银行帐户中记录余额的累加器减去这些金额。 这些部门还用于在累加器中增加代表用户银行账户中的存款的金额。 这些扇区被手动提前到不同的数量，表示从原始位置的位置，其中它们定位要打印的特殊符号以代替数量。 打印完毕后，这些扇区返回原位，在这个移动过程中，数字化了累加器。 推翻防止手段暂时将部门和蓄能器逮捕在零注册行业。 然后将累加器脱模，并且扇区进一步返回到原位。 提供相互啮合的检查定位构件以调整相对于印刷线的检查。

Abstract: An inexpensive torque transmission device is provided which is applicable as either a brake or a clutch and comprises a conical friction element axially slidable between two relatively rotatable members. The element has a friction surface engageable with one of the members and a toroidal tension spring is tensioned between its conical face and the other of the members to exert a yieldable force urging the element into frictional engagement with the first member thereby transmitting a predetermined torque between the two members. The spring also reduces any tendency for the friction element to rotate relative to the second member.
