Title: Childproof closure for a container comprising a lower portion with extensible spout and a screw cap
Inventor: STOLZ HEINRICH
IPC: B65D47/06
Filed: 1993-03-25
Abstract: The invention concerns a closure for a container, comprising a lower portion and a screw cap. The lower portion can be connected to the container opening by a base unit and has a pouring spout. The pouring spout is connected to the lower portion by an elastic extensible bellows, and the screw cap with the cap base and the cap casing, which is provided with an inner screw thread, can be screwed on and off the pouring spout which has an outer screw thread. As a simple child-proofing feature, the pouring spout of the lower portion is provided with at least one stop lug outside screw thread in the transitional area facing the bellows, the lug has a flat leading edge in the screw-on direction and becomes a steep detent edge, so that the cap casing is locked with the stop lug in the screw-on position and prevents the screw cap from being unscrewed. By depressing the bellows in the region of the stop lug, the engagement of the screw cap with the pouring spout can be broken and the screw cap can then be unscrewed.

Title: Flow refrigeration valve
Inventor: MILLER KENT A
IPC: F16K5/20
Filed: 1994-10-05
Abstract: IMPROVED FLOW REFRIGERATION VALVE                ABSTRACT OF THE DISCLOSURE A valve, such as a compressor or line service valve, for use in refrigeration or air conditioning fluid circuits having an improved flow for improved energy efficiency is disclosed. The valve incorporates a rotary ball member with a 90° fluid passage diameter that is equal to or greater than the diameter of the fluid line that it services. Rotation of a primary actuator stem rotates the ball member to open and close the valve. An annular ball seal provides a seat against which the ball may be positively sealed. A secondary stem is aligned on an alternate axis from the primary stem that is preferably collinear with a fluid line. The secondary stem effectuates a positive engagement between the rotary ball member and the ball seal. A plunger cooperates with locator indentations and a groove in the rotary ball member to center the ball within the valve and align its fluid passage with fluid line connectors. Locator indentations also ensure that the rotary ball member is properly oriented when in either the opened or closed positions. When the secondary stem is engaged, iteffectuates a positive shut-off force to seal the ball member against the ball seal.

Title: Audio distribution system with controllable volume override
Inventor: FARINELLI ROBERT P JR
IPC: H04R27/00
Filed: 1994-10-04
Abstract: A signal distribution and communication arrangement includes a main control unit (10) remotely located and electrically coupled to a volume control panel (48). The volume control panel (48) is located near a speaker (14), and the main control unit (10) sends substantially continuous audio signals (20) or an interrupting audio signal (22) to the volume control panel for playing via the speaker. These signals can be sent on the same conductor (32) or separate conductors. When the interrupting audio signal (22) is present, a voltage or current source (40) provides a level from the main control unit (10) to the volume control panel (48) to indicate that a volume override circuit (50) should be engaged. Upon engagement of the volume override circuit (50), the interrupting audio signal is passed through to the speaker at a prescribed signal level, regardless of the volume control setting (54) on the volume control panel.
