Abstract: A highly portable, disposable, self-contained timer (1) provides a user-perceptible signal at automatically-successive, fixed time intervals to alert the user as to the times for taking medications. The time intervals are not variably programmable, and dif­ferent timers having different fixed time intervals are provided for use with different medications. Prefer­ably, the time intervals are nonuniform, comprising multiple shorter intervals combined with a longer interval corresponding to a normal sleeping period so that, when the timer is initialized in accordance with the user's sleeping cycle, no signal is emitted while the user is asleep. The device is powered by a non-­replaceable battery for economy and disposability, and a deactivator circuit (48) is included which permanently disables the unit after a predetermined length of time well within the life of the battery. A signal emitted by one of a number of timers is easily distinguished, without requiring an audible signal of excessive duration, by a visual signal of substantially longer duration than the audible signal. The timer has an audible signal buzzer (14) and a visual signal LED (16).

Abstract: A coin cassette for a coin-operated machine (5) consists of a container (1) and a cover (2) which are connected by means of a hinge (6). Arranged on the cover (2) is a protective housing (12) which contains a sleeve (13) with a hook (15) located outside the sleeve (13). When the coin cassette is being pushed into a housing (4), the hook (15) catches in a lug (14) penetrating into the protective housing (12) and connected to the housing (4). When the coin cassette is removed from the housing (4), the hook (15) transmits a mechanical movement to a lever mechanism (17, 17', 20, 27) by means of the sleeve (13) and by means of a compression spring (18). The lever mechanism (17, 17', 20, 27) closes by means of a closing piece (10) an entry orifice (8) for coins and is locked by means of a notch (22) and by means of a pawl (24) anchored in the container (1). A return spring (29) drives the closing piece (10) back from the entry orifice (8) as long as the lever mechanism (17, 17', 20, 27) is not locked. Means for the damping of movements of the closing piece (10) prevent an unintended closing and locking of the entry orifice (8). The lever mechanism (17, 17', 20, 27) is released automatically when the cover (2) is swung up from the container (1). <IMAGE>

Abstract: A variable displacement hydraulic pump (11) and a hydraulic motor (18) are connected in a closed circuit (17A, 17B). A pressure oil supply means (100) includes the variable displacement hydraulic pump (11) and a tilt controlling means (16) for controlling the tilt angle of the hydraulic pump (11) and supplying an amount of oil, corresponding to the tilt angle of the hydraulic pump, to the hydraulic motor (18). When rotation of a prime mover (6) is detected by a rotation detecting means (101), an opening and closing valve (102) is changed over to a first position in which the pressure oil supply means (100) is permitted to supply oil. When stopping of the prime mover (6) is detected by the rotation detecting means (101), the opening and closing valve (102) is changed over to a second position in which the pressure oil supply means (100) is inhibited from supplying oil. Upon starting of the prime mover (6), at least the opening and closing valve (102) remains in the second position, and the tilt controlling means (16) increase its tilt angle from its neutral position so that the pressure oil supply means (100) supplies oil. Consequently, upon re-starting of the prime mover (6), oil is prevented from being supplied inadvertently to the hydraulic motor (18), and the safety upon starting is assured.
