Abstract: A one-piece removable carrying handle assembly (10) for removably attaching the handle assembly to an item to be carried. The carrying handle has a middle strap portion (18) with two end portions (14, 16). Each end portion (14, 16) includes a housing member (28, 24) that has a slot (44) adapted to receive attachment hardware. The attachment hardware includes a screw (30, 36) and a spacer (32, 38). A screw (30, 36) and a spacer (32, 38) fit through slots (22, 24) in the end portions (14, 16) of the assembly (10). Each housing (28) is designed to be positioned over a screw (30), spacer (32), and a slot (22) so that each end portion of the strap assembly (10) contains all separate parts and so that each end portion is lockingly attached to the middle strap portion to form a one-piece unit.

Abstract: A programmable thermostat features a memory unit receptive of unit values of temperature desired at different times on different days all individually or in various combinations both as to days and times. An output device signals a temperature control system. As controlled by a clock, the memory unit is addressed during different times of the different days to provide a signal representing the corresponding value desired. Existing temperature level is sensed and compared with each value so as to develop an error signal. In response to that error signal, the output is operated in a direction to reduce the difference between actual and desired temperatures. Numerous details as to layout, construction and circuitry are presented.
