Abstract: A can crusher has a removable arm member hingedly connected to a base member, and the arm member has a crushing portion which is received in nested fashion by a can receiving portion on the base member. The crushing portion has a bearing wall with a lip and a plurality of struts perpendicular to the bearing wall. The lip extends above the struts. The base member has a step pad so that the can crusher may be either wall mounted or portable. The lip engages the rim on a container to be crushed to captively secure the container between the lip and the base member. This avoids accidental ejection of the container from the can crusher. When the arm member is in the open position, the lip is spaced from the base member a sufficient distance to accommodate aluminum beverage cans, steel cans and plastic bottles of common household sizes. The struts may also be provided with protective elements to prevent undue wear on the crushing portion.

Abstract: The apparatus comprises a plurality of connectors (9, 10, 11, 12 . . .) for connecting to the component to be tested (e.g. a transformer), a signal generator (19), a measuring system (23) and control means (22) which is arranged to control which of the connectors (9, 10, 11, 12 . . .) are connected to the signal generator (19) and the measuring system {23) and arranged to control the function of the signal generator (19) and the measuring system (23) so that the same signal generator (19) and measuring system (23) can be used to carry out a variety of different tests on the component, the signal generator (19) also being arranged to provide a synchronising signal (28) to the measuring system (23) so that the phase relationship between measurements at different times can be calculated by comparing the phase relationships of those measurements with the synchronising signal (28).

Abstract: A comfortable, protective eyeglass cover for the temples and earpieces of a pair of eyeglasses is disclosed. The protective cover includes a pair of sleeve members with each of the sleeve members having a hollow interior and an opening at a first end extending into the hollow interior. Each of the sleeve members is configured to receive one of the temple and earpieces of the eyeglasses within the hollow interior through the opening. The protective cover increases the comfort to the user as well as tightening the grip of the eyeglasses.
