Abstract: A packaging system for encapsulating an article within a solid foam material. An article to be encapsulated is supported on a base. A wall enclosure is disposed on the base to form a mold cavity. At the top of the base and above the article to be encapsulated is a cover. Expandable plastic foam in liquid form is introduced into an orifice of the base and the expandable plastic foam advances through a passageway in the base and is discharged from an orifice in the base into the mold cavity to encapsulate the article. The foam material in liquid form solidifies into a solid plastic foam material for packaging the article.

Abstract: Apparatus for sequentially printing characters along a ribbon or paper tape in response to receiving a sequence of touch tone signals. The apparatus comprises a touch tone decoder and a printer. Included in the touch tone decoder is a dual tone multiple frequency analyzing circuit which receives the touch tone signals and transmits therefrom BCD signals and control logic signals. A select function control circuit is responsive to the BCD signals and the control logic signals to select an ROM memory from a group of ROM memories. A select letter control circuit receives the BCD signals and the control logic signals and addresses the selected ROM memory to produce a parallel multiplex output signal for controlling the operation either of a matrix or a line print head of the printer. Included in the printer is a motor circuit and a control circuit to advance the ribbon or paper tape past the matrix or the line print head.

Abstract: A machine for cleaning, polishing and otherwise finishing floors includes a friction-type mechanism for holding the handle of the machine in a preselected position, a dead-man switch control lever arranged for pivotal movement toward and away from the switch it controls, and an effective splash guard. Also disclosed is a helical gear transmission for driving the finishing pads, and a handle that has surfaces particularly adapting it for comfortable gripping by the operator's hands and for non-injurious contact by other parts of the operator's body.

Abstract: A system for monitoring the operations of a person, such as a bartender, who has under his control a number of containers, such as bottles of liquor, from which he dispenses individual portions, and for keeping a running inventory of all the containers that are available to the operator at the beginning of a work period. The system includes a work station that has a compartment for retaining an array of containers from which the operator is dispensing portions, a container identifying and disposal unit for receiving empty containers presented to it by the operator, and a storage unit arranged to hold a plurality of containers and dispense one of the containers after the operator presents a similar container to the identifying and disposal unit.

Abstract: A panel construction for surfacing roof or siding structures of a building. Each panel is made of flexible composition and as applied, its lower horizontal edge is associated with a strip that provides a distinct shadow line.

Abstract: This invention relates to the resurfacing of composition roofs and sidings, and more particularly concerns an assembly made up of a weatherproof membrane and a nailing strip secured to the membrane along one edge of the membrane so that, after the nailing strip has been nailed into the old roof, the membrane can be folded over the nailing strip to cover the strip and a portion of the old roof above the strip.

Abstract: Telephone instruments have an apertured base through which project depressible dialing elements, such as touch tone keys or push buttons. A locking device for telephone instruments with depressible keys or buttons comprises a body fixed to the base and formed with a bore therethrough. Disposed within the bore of the body is a movable member that has one end thereof projecting over a depressible dialing element. By moving the movable member in one direction, a depressible dialing element is depressed to lock the telephone instrument. By moving the movable member in an opposite direction, the depressed dialing element under its own yieldable action rises to become fully extended to enable the telephone instrument to be operated.

Abstract: An attention signal receiver in which emergency broadcast transmissions are detected from various locations. A scanning circuit sequentially activates means to produce a plurality of oscillating frequencies which mix or beat with the incoming r.f. signals. An attention signal is a two tone signal that includes both a 960 H.sub.z frequency signal and a 853 H.sub.z frequency signal. The audio stage of the receiver is connected to a two tone decoder that passes only a 960 H.sub.z signal and a 853 H.sub.z signal. A squelch circuit is also connected to the audio stage of the receiver. Connected to the output of the tone decoder is a one second time delay circuit and a ten second time delay circuit. If an attention signal is detected for a period of time in excess of 1 second, the one second time delay circuit stops the scanning of the scanning circuit to lock in the receiver to the first carrier detected with an attention signal. The ten second time delay circuit normally disables the squelching circuit.

Abstract: A shock and vibration mount includes a resilient elastomeric member arranged to act with two spaced spring units, each of which includes a group of stacked, disc-shaped annular springs. Low level impacts and vibrations are transmitted from a rod, that is movable with the impacted member or with a member reacting to an impact, to the elastomeric member through either of the stacked units, high intensity shocks being attenuated first by the elastomeric member and then by one of the stacked units.

Abstract: Apparatus for volumetrically feeding dry flowable bulk material. The apparatus comprises a hopper that receives dry flowable bulk material from a storage tank of dry flowable bulk material through a rotary valve located at the top of the hopper. At the bottom of the hopper is a sliding discharge gate for the discharge of dry flowable bulk material from the hopper. Mounted on the hopper in vertically spaced relation is a high level sensor and a lower level sensor. When the height of the dry flowable bulk material in the hopper is above a predetermined height, the high level sensor is activated for the closing of the rotary valve and the opening of the discharge gate. When the height of the dry flowable bulk material in the hopper is below a predetermined height, the low level sensor closes the discharge gate and opens the rotary valve. Thus, the bulk material level in the hopper is maintained within prescribed limits to control the pressure head of the bulk material for improved feed accuracy.

Abstract: Apparatus for translating sound into a visual display comprising means for producing audio signals. The audio signals are advanced over a plurality of paths. Over one path, the audio signals are detected for voltage amplitude. Should the voltage amplitude fall within a predetermined range, a valve is operated to control the flow of liquid from a pump to a set of nozzles. Over another path, the audio signals are detected by tone detectors for dominant notes falling within various frequency bands representative of the melody of the audio signals. A resultant voltage is a function of the band of frequencies over which the dominant notes are detected. The flow of liquid from a set of nozzles is proportional to the amplitude of the voltage resulting from the band of frequencies over which the dominant notes are detected. Lamps of various colors are selectively illuminated in accordance with the band of frequencies over which the dominant notes are detected.
