Abstract: An apparatus is provided for testing of bonded laminates which include a substrate and a face sheet bonded thereto. The apparatus has at least one air nozzle arranged to direct high velocity air in a direction generally radially outward of the circular pattern at a shallow angle to the face sheet of the laminate. A detection plate on the examining surface of the device is encircled by the air nozzles. The detection plate has associated therewith means for detecting when the face sheet of the laminate is deflected toward the detection plate, indicating that the laminate is not bonded to the substrate in that area. High pressure air is introduced through the air nozzles thereby producing an air cushion between the examining surface of the apparatus and the face sheet of the laminate and simultaneously producing a vacuum in the area between the detection plate and the face sheet, whereby the face sheet will be deflected toward the detection plate in an area where the face sheet is not bonded to the substrate.

Abstract: In an instrument assembly (1) a current value indicator element (6) is rotatably mounted on a shaft (5) and a set value indicator element (12) is controlled by a knob (14) and is mounted in the glass face (10) of the instrument for rotation about the axis of the shaft (5). Spur gears (9, 13) connect the set value indicator element (12) to a shaft (8) serving as input to a signal outputting means (7).

Abstract: An infant carrier has a handle which can be detachably coupled to a hanger on a swing. The handle is U-shaped and pivotably connected at its free ends to the carrier shell body by a latch means so that the handle can be latched in different angular positions.

Abstract: A platform, for use in a sheet stacking device in which the platform descends as a stack being formed on it grows higher, is so constructed that its length can be varied according to the length of sheets to be stacked. The platform is made in two or more sections (10, 11, 12) each hinged (15, 17) to the next, and all sections are supported horizontally to receive long sheets, less than all the sections being horizontal and the remaining sections hanging vertically when shorter sheets are being stacked. Wheels (13, 16, 18) may be provided on the platform so that it may easily be moved out of the stacking device when loaded, all the sections being restored to a horizontal position for such movement.

Abstract: The piston metering pump has a motor operated eccentric which reciprocates a piston assembly. The piston assembly has two separate portions connected by spaced wire or rod members. One of said portions supports the piston and the other portion supports a coaxial stroke adjustment member.

Abstract: A programmed digital secondary clock which functions as a master clock, a sub-master clock or a slave clock. The master clock maintains an updated real time count based on a 50 hz or 60 hz ac line or digital oscillator signal, displays the count, and serially transmits digital information representative of the updated real time count for use by a slave clock. The sub-master clock, receives an hourly or twice-a-day correction signal from a conventional master clock or a conventional electronic receiver, corrects the real time count, displays the corrected count, and serially transmits digital information representative of the corrected real time count for use by a slave clock. Identical programmed digital secondary clocks can be connected in daisy chain. The first clock can operate as a master clock or as a sub-master clock. The following clocks can be operated as slave clocks.

Abstract: Steam is generated in a small enclosure disposed within a large tank. Water is separately heated in the enclosure and in the tank. The enclosure is in direct communication with the tank. Steam generated within the enclosure is connected to a dispensing nozzle for use in connection with food and beverage products.

Abstract: The apparel is an uninsulated vest having insulated arms and adapted to be worn underneath a sleeveless insulated jacket.

Abstract: An end block adapted for use on a kiln car includes a refractory body having a transverse projection at a front end and a transverse recess at a rear end. The recess is dimensioned to receive therewithin a projection on the front end of another block with a loose fit therebetween. A sealing layer of resilient refractory material may be disposed within the recess for contact with the front end projection of another block.

Abstract: The device is attachable to the lower end of a swinging door to control draft between a sill and the lower edge of the door. The device includes a roller supported at its ends by support assemblies which are removably attached to a pair of brackets on the door. Mating surfaces on each assembly and its associated bracket prevent cocking of the bracket. The ends of the roller are supported by a pair of support members which are non-rotatable, guided for vertical movement, and spring biased downwardly while being provided with an adjustable limit stop.

Abstract: A heat exchanger is retrofitted by removing old heat exchange tubes. If there is no access passage into the shell, an access hole is cut in a wall of the shell. Modules preformed from zig-zag elements are introduced through the access passage and assembled into a tube support panel within the shell between adjacent support plates. The heat exchanger is retubed so as to support the new tubes by the existing support plates and by said panels.

Abstract: An asynchronous interface includes two memories which store multiplexed keyboard information such that while one memory is writing in newly acquired key information from one musical instrument system at the clock rate of that system, the other memory is reading out previously acquired key information to a second musical instrument system at the clock rate of the second system. Periodically, based on timing signals derived from both systems, the read/write roles of the two memories are reversed. Any number of asynchronously clocked systems, each connected to an associated asynchronous interface, may be keyed by a single key multiplexing device or by the multiplexing information from another asynchronous interface.

Abstract: A process for diagnosing the presence of hypertension or a predisposition to hypertension in a mammal comprises detecting the presence in a body fluid of the mammal of at least one protein associated with hypertension wherein the protein has a relative molecular weight of about 10,000 daltons to about 17,000 daltons. In humans, the process detects the presence of or predisposition to essential hypertension as distinguished from secondary hypertension. A preferred analytical method is discontinuous sodium dodecyl sulfate polyacrylamide gel electrophoresis.

Abstract: An apparatus is provided for suspending one or more long-shafted forks in a vertical position for storage and in a horizontal operative position whereby the forks may be used to hold food over an open heat source. The apparatus comprises a base having dimensions sufficient to provide vertical stability, a stand post mounted vertically to the base, an upper bracket adapted to hold the forks vertically at the handles, and a lower bracket having a cradle and hook retaining means for retaining the forks horizontally in the second operative position. The lower bracket is also vertically movable along the stand post, and the hook and cradle retaining means are pivotable about a cross bracket portion of the lower bracket whereby the forks may be adjusted horizontally over the heat source.

Abstract: An ultraviolet light beam is split into two beams which are directed toward a reference cell and a sample cell, respectively. A mechanical rotating light chopper permits the reference and sample cells to be alternately illuminated. Radiation from the reference and sample cells is directed toward and sensed by a single photomultiplier tube. An up/down counter counts the number of photons impinging on the photomultiplier tube from the reference and sample cells. Photodiodes in conjunction with the mechanical light chopper cause the up/down counter to count up when photons are arriving from the sample cell and cause the up/down counter to count down when photons are arriving from the reference cell. A source intensity monitor prohibits further measurements after a preselected amount of incident flux has been sensed. The intensity monitor includes a photodetector circuit which senses a portion of the incident light.

Abstract: The nameplate device includes a shadow box mounted on a support. A spacer is secured to the center of the rear wall of the shadow box and to the rear face of an engraved plate. The engraved plate is parallel to the rear wall and spaced evenly from the side walls of the shadow box in a manner so that the details of how the plate is attached to the rear wall are concealed.
