Abstract: Insulating fabric having a knitted base fabric incorporating air-entrapping cells on one or both sides. The base fabric is knit from a bulk acrylic yarn, preferably high bulk acrylic yarn, and a combination polyester and cotton yarn, the yarns being knitted separately in selected fabric courses. The inner face of the fabric is formed of the bulk acrylic yarn, to provide a soft, warm and comfortable interior surface when worn. The outer face of the fabric is formed of the polyester/cotton yarn, which provides a knitted framework for anchoring and stabilizing the high bulk yarn in the fabric. Following knitting, the fabric is subjected to a series of finishing operations which include scouring, padding, drying and calendering. Preferably, the inner acrylic surface of the fabric is napped prior to calendering. As the result of repeated washings, the insulating fabric of the invention increases in thickness to enhance its heat insulating capability and provide increased warmth.

Abstract: An alarm device for a construction vehicle including a transceiver adapted for mounting at the rearward end of a vehicle for directing its wave output rearwardly of the vehicle. Return wave signals for many objects within the transceiver range are picked up and supplied to the transceiver by an antenna. Any resultant doppler shift signal is amplified for driving an audio alarm positioned on the vehicle. The circuit is adapted for electrical connection to the reverse gear of the vehicle for activation only when the vehicle transmission is engaged in reverse gear.

Abstract: A method and apparatus for interrogating a transparent photostimulable luminescent screen is characterized by positioning the screen with respect to a virtual point source of interrogating radiation such that the scanning interrogating radiation passes through the screen along the same paths as did the imaging beam.

Abstract: A movable panel member incorporating an integrated electrical current distributing busbar which, for the electrification of work stations in particular, forms a screen, partition, table top, table frame, shelf, cupboard, or the like. Adapters are detachably insertable in the current distributing busbar for the supply and distribution of current. The panel member comprises at least along one edge, a channel member forming a current duct in which there is inserted a current distributing busbar, and a communication duct, separated from the current duct by means of a partition for the accommodation of communication cables. The inlet ends of both ducts are open in opposite directions on opposite sides of the panel, and they are adapted to be closed off by means of detachable covers.

Abstract: Heteropentathiepins including pyrazolopentathiepins substituted in the 8-position; intermediate pyrazolo-1,2,3-thiadiazoles, pyrazolothiazathiolium chlorides, and 5-substituted aminopyrazoles; process for making the pentathiepins by reacting the corresponding 1,2,3-thiadiazoles with sulfur at elevated temperatures; process for making the thiazathiolium chlorides; and use of the pentathiepins as fungicides or as sulfur sensitizers in photographic emulsions.

Abstract: A resistance heater element for an electric room heater includes a resistive heating conductor (1) supported by an insulating support (2) mounted on the support flange (9) of an electric fan (4) in the heater which passes a stream of room air across the conductor (1). The insulating support (2) is cylindrical, with its axis parallel to the direction of the air stream, and includes at least one pair of nested mica bands (5, 5') bound together by fillets (6) connected to the support flange (9). The heating conductor (1) comprises at least one wire of resistive material bent in a zig-zag manner to form a plurality of radial loops each having portions extending inwardly and outwardly of the cylindrical bands (5, 5'). The central portion (11) of each loop is bent over and retained between the pair mica bands (5, 5') with the inner portion of each loop emerging radially from the inner band (5) through apertures (13) provided therein.

Abstract: The amount of textile warp size added to a sheet of threads in a running slasher is controlled by measuring the force applied to a separator bar, by passage of alternate threads on alternate sides of the bar. This force is the result of the dried size, which causes adjacent threads to adhere to each other. The force is compared to a predetermined value corresponding to the desired amount of size to be added to the threads. Based on this comparison, the pressure on the nip rolls is adjusted in order to squeeze more or less of the size solution from the threads. In this way, the amount of size added is maintained substantially equal to the predetermined value.

Abstract: Improved liquid electrostatic developer containing electrostatic toner particles is prepared by a process wherein an aqueous, e.g., water-wet pigment cake is flushed with a water insoluble vehicle, water is removed, and the developer is formed from the flushed pigment dispersion, thermoplastic resin, dispersant nonpolar liquid having a Kauri-butanol value of less than 30, in a vessel at elevated temperature under high shear, and the dispersion is cooled. The liquid electrostatic developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.

Abstract: A security seal having a plastic body including three elongated parallel chambers. Mating with the body is a U-shaped resilient shackle having a pair of legs each having a reversely bent end portion terminating in a sharp edge for insertion in two of the chambers. The third chamber in the body contains a frangible ampule containing a liquid dye. When used to seal a structure, the shackle is threaded through the structure, and the legs are inserted into the chambers. The sharp edges of the reversely bent end portions are flexed into tight engagement with the interior walls of the chambers.

Abstract: A direct drive servo valve includes a valve housing having a cylindrical bore and a valve spool mounted for movement in the bore for controlling fluid flow through said valve housing. The valve spool has a drive well located in the spool transverse of its longitudinal axis. A motor secured to the valve housing includes a rotor which is rotated in response to a drive signal applied to stator windings of the motor. A shaft attached to the rotor for rotation therewith includes a substantially spherical drive tip, the spherical tip positioned eccentrically to the longitudinal axis of the shaft and being close fitted into the drive well. In operation, as the shaft rotates through a given angular rotation, the spherical tip rotates in a circular path to provide linear displacement and rotational motion to the valve spool.
