Abstract: The fire resistant, pre-stressed structural flooring carrying beam of steel includes two vertical webs (2) and a bearing plate (4) along the bottom of the beam extending out­side the webs (2) for bearing the floor structure, the upper side of which is above the upper side of the steel beam after finished concrete pouring. The webs (2) are those of two channels (1) fixed to the bearing plate (4) with their toes in opposing, mutual, spaced relationship. The upper flanges (5) of the channels are provided with projecting means (6, 6′) fixed at pre-determined mutual spacing along the beam. An open space between the channels (1) is thus pro­vided between the toes of the channels for filling with con­crete (10) when concrete is poured, such as to achieve static co-action between the steel beam and concrete via the means (6).

Abstract: A differential capacitive sensor contains two sensor electrodes, each one of which is opposite to a transmitter electrode fed by an electrical alternating-voltage source. A circuit arrangement connected to the two sensor electrodes for obtaining a signal generates a difference signal which corresponds to the difference between the displacement currents induced in the two sensor electrodes. The circuit arrangement contains a series resonant circuit the frequency of resonance of which corresponds to the frequency of the alternating- voltage source. The two sensor electrodes are coupled with opposite polarities via a transformer to the series resonant circuit and the difference signal is picked up at the tap of the series resonant circuit formed by the junction between coil and capacitor.

Abstract: A packaging material and a method of forming the packaging material into a flexible, disposable food container adapted to contain and maintain food in a fresh and sanitary condition, and to ship, display, heat and brown, and serve the food is disclosed. The method includes forming patches of microwave interactive material (18) on a web of plastic (14) and laminating the web of plastic to one side of a web of structural stock material (12) to form a composite web (10); the microwave interactive material is sandwiched between the web of plastic and the web of structural stock material. Sealant (20) is applied to portions of the plastic layer in registry with the patches of microwave interactive material to seal ends of the composite web. Printed graphics (24) are applied to portions of the structural stock material layer in registry with the patches of microwave interactive material and the sealant. The formed container is sufficiently flexible to contain food having curved and irregular surfaces and to maximize contact of the food with the portion of the container housing the microwave interactive material. The container is sealed so that portions of the composite web extend as fins (22) beyond the sealed ends of the food-containing portion of the container. The container also is capable of receiving food before the food is frozen to prevent portions or parts of the food from falling out of their proper place in the food packaging process.

Abstract: An absorption-cycle heat pump comprises a rotary assembly including a vapour generator (GE,14), a condenser (C0,23), an absorber (AB,22), an evaporator (EV) and a solution heat exchanger (X,16). The vapour generator, the condenser and the absorber each include a wall (14, 23, 22 respectively) across which the volatile component (preferably water) and/or a liquid absorbent therefore are caused to flow under the action of the forces generated during rotation of the assembly. The evaporator comprises a plurality of finned heat exchange tubes 31 into which the volatile component is injected with a radially inwardly-directed component of motion, the tubes being of generally elliptical configuration disposed with their major axes extending generally radially. To maintain the evaporator heat exchange surfaces continuously wetted, excess volatile component is supplied such that a major part of the latter remains unvapourised after flow across the evaporator heat exchange surfaces and is collected in a reservoir (26), which also receives the condensate from the condenser, for re-injection into the evaporator tubes (31).

Abstract: The backshell (10) is provded with a unitary ratcheted tie strap (16) for strain relief connection of a cable (20) (see Fig. 2) to the backshell. The backshell comprises a base (12) for receiving an elec­trical connector (18) (see Fig 2) therein and a cover (14) hingedly connected to the base for environmentally protecting the electrical connector (18) therein. Resilient latches (100) lockingly retain the cover (14) to the base (12). The interengagement of the cover (14) with the base (12) prevents outward bowing of the base side walls (26, 28). The ratcheted tie strap (16) lockingly engages a deflectable ratchet trigger (70) (see Fig. 7) which also is unitary to the base (12). The trigger (70) is angularly aligned to walls (52, 62) of a tie strap receiving aperture (66) and is dimensioned to exert a biasing force against the tie strap (16) thereby preventing loosening of the strain relief connection.

Abstract: An asynchronous interrupt status bit circuit for use in conjunction with a microprocessor, which guarantees that no interrupting conditions are missed and that no single interrupting condition is indicated twice, includes a master latch (12), a transfer gate (14), a clocked latch (16), an inverter (18), an output driver circuit (20), and a clearing circuit (22, 24). The master latch (12) is responsive to an interrupt input signal for generating an interrupting logic signal at its output which is latched to a low logic level. The clearing circuit (22, 24) is responsive to a control signal for generating a clear signal to clear the output of the master latch (12) to a high level only when the control signal is latched at a high level before the time a true read signal is making a high-to-low transition. The next read signal causes an output signal having a low level to be read by the microprocessor if no interrupt input signal has occurred.

Abstract: An improved process for reacting a mercaptan-­terminated aliphatic polysulfide resin with excess epichlorohydrin in the presence of alkali to form an epoxidized polysulfide is disclosed. The reaction takes place in the absence of a solvent such as ethyl alcohol or ether, which will form an inseparable azeotrope with epichlorohydrin and water. The reaction is carried out at a temperature and pressure sufficient to distill away epichlorohydrin and by-product water. The water and epichlorohydrin are separated and the epichlorohydrin is returned to the pot during the reaction. After the reaction is complete, the epichlo­rohydrin is stripped, leaving an epoxidized polysul­fide, by-product sodium chloride, and residual alkali. The epoxidized polysulfide is dissolved in a work-up solvent and filtered to remove sodium chloride and alkali. Then the work-up solvent is stripped, leaving a purified product.

Abstract: A dynamic head position tracking control for a magnetic tape playback system employs a detected dither signal to determine the elevational position of a pair of magnetic transducing heads relative to tracks of recorded information being scanned by the heads. This detection is carried out at several locations along the lengths of the tracks being scanned, and a value is stored for each of the locations. Based upon the stored information, an estimation is made of a position value for the first location along the length of the tracks. This estimation is determined from a weighted extrapolation of the following two samples taken during the scan of the track. The elevational position of the heads is then dynamically controlled in accordance with the actual and estimated head position values.
