Abstract: A two-wire telephone line interface circuit comprises a driver circuit (10) for supplying direct current on the line (13), a controlled voltage generator (14), a sensing circuit (12) for monitoring the line current, a control circuit (15) for controlling an out-put voltage (CV) or the voltage generator, and a switching circuit (11).  The control circuit controls the switching circuit to supply, as a supply voltage (DV) for the driver circuit, a battery voltage (BV) in an on-hook state of the line or the controlled output vol-tage of the voltage generator in an off-hook state of the line, this output voltage being controlled to provide off-hook current limit-ing.  The control circuit also controls the switching circuit to selectively supply the controlled output voltage of the voltage genera-tor as a signaling voltage to at least one wire (TV, RV) of the line for high voltage signalling, e.g. ringing, on the line.  Desirable forms of the switching circuit are described.

IPC: E04C2/288
Filed: 1992-07-22
Abstract: A composite structural material and the method of making a low cost, lightweight, ductile, long lasting, crack resistant, composite structural material which consists of a core (12) constructed from lightweight, expanded foam. The core is covered on one or more of its sides with a high strength outer layer (14) constructed of a layer of layers of non-woven web fibrous material impregnated with a cementitious slurry binder (22) with the fibers in the layers of non-woven web material forming a three-dimensional reinforcement matrix (18) for the cementitious slurry. The outer layer is formed and cured on one or more surfaces of the lightweight plastic core resulting in a crack resistant outer layer having greater ductility and thoughness than ordinary cement or concrete.  The cement in the outer layer bonds directly to the lightweight plastic core thus requiring no additional bonding agent. Outer layers can be formed and cured around various shaped cores for various end uses.

The valve (54) inoperative to open and close the bypass passage (58) in response to engine operating parameters and to modulate the flow area of the passage; (58) in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve (54). The valve (54) is modulated to operatively maintain the bypass passage (58) at least partially open at engine idle, whereby the valve means (54) permits bypass flow to recirculate air flow from the blower outlet (40) to the inlet (38) to reduce ar limit the engine power absorbed by the blower (37) or to conduct additional air flow around the blower (37) directly from the turbo-compressor (41) to the engine intake to avoid the restriction of the blower (37) to increased charging air flow. A single valve means thus provides a dual function capability.

Abstract: A variable proportion dispenser (2c) includes a housing (12c) which houses two pharmaceutical cartrides (6b). A reciprocating drive assembly includes drive stems (36c) extending from the pistons (46b) of each cartridge, a limit guide (76c) removably mounted to the housing, and a sliding body (66e, 300) mounted to the housing through the limit guide.
