Patent PT-95488-B (PT)
Inventor: LIN SZU-MIN
IPC: A61L2/28
Filed: 1990-10-02
Abstract: The invention relates to a test pack having a housing defining an inner volume and an opening for communication between the inner volume and the environment outside of the housing. A divider divides the inner volume into two portions. A first portion of the inner volume has an absorber positioned therein to retard passage of the sterilization atmosphere. A chemical indicator to indicate exposure to the sterilization atmosphere may also be positioned within the first portion. The second portion defines a blind reservoir which contains a biological indicator for testing for successful completion of the sterilization procedure.

Abstract: 1,018,910. Retractive switches. OLYMPIA WERKE A.G. Oct. 30, 1963 [Nov. 7, 1962], No. 42840/63. Heading H2B. A push-button operated switch for use in electric typewriters, for example, comprises an insulating body 1 of U-shape having lugs 2 which pass through slots in a mounting plate (not shown) and are retained by a wire spring clip 14 engaging slots 2<SP>1</SP> as shown. The clip 14 also passes through a slot 6<SP>11</SP> in a reciprocable member 6, thus resiliently limiting the travel thereof in each direction. Member 6 carries a button 15 and a contact spring 11 in the shape of an inverted W which bridges two fixed contacts 9 when the button is depressed.. A spring 8 provides retraction. The contact 11 straddles an insulating moulding 10 on member 6 and is normally held against shoulders 10<SP>1</SP> by a pin 12. The lugs 2 are arranged obliquely to the body 1 so that a plurality of switches may be mounted in close proximity without interference between the clips 14 (Fig. 4, not shown). The mounting plate may be stepped to carry switches in rows at different levels, or it may be inclined (as indicated by broken lines in Fig. 2, not shown), in which case the top of body 1 is made to slope correspondingly.

Inventor: HOOPER L A
IPC: A63B22/06
Filed: 1977-10-17
Abstract: A cycle exerciser having a vaned wheel rotatably mounted on a frame and arranged to absorb energy by movement of the broad surfaces of the vanes against the surrounding body of air. Rotation of the wheel is effected through a pair of foot pedals and connected chain and sprocket mechanism, and/or through a pair of handle bars. Each handle bar is pivotally connected to the frame and is also connected to a respective eccentric through a crank ring rotatably mounted on that eccentric and a drive bar connected to both the crank ring and the handle bar. The two eccentrics are arranged 180 DEG out of phase and are connected to the foot pedal assembly so as to rotate in response to both pivotal movement of the handle bars and operation of the foot pedals. As the eccentrics are drivably connected to the vaned wheel, that wheel is caused to rotate in response to rotation of the eccentrics.
