Abstract: The present invention combines the advantages of a prior art figure of 8 winding pattern with the traditional circular or oval pattern for packaging flexible cord to form what can be called a "figure of 80 pattern" which includes a generally S-shaped partial cord layer with the end of the S joining with a J-shaped portion arranged so that the straight portion of the J forms a continuation of the S and the curved portion of the J overlies the beginning of the S-shaped portion. This basic combination of S and J shapes designates only partial layers, the pattern can be repeated, that basic pattern can be connected to a plurality of oval turn layers or even a plurality of figure 8 turn layers as the user may elect. It is also possible to continue to merely alternate the basic layer form to provide a package having a high packaging density while permitting easy accommodation of fittings which are secured to the end of the cord.
Abstract: A fiber optic treatment probe (10) delivers laser light from a laser light source (11) through a diffuser (26). An input end face (30) of the fiber is angled with respect to a plane (36) normal to an optical axis (18) of the fiber. The end face angle is selected to excite desired modes of the fiber without exceeding the critical angle of the fiber, thereby producing a desired light output from the diffuser.
Abstract: In making integrated linings to be applied to spines of a succession of books in a bookmaking process, a high speed low cost method is disclosed which includes feeding strip stock from a supply of lining material, printing simulated headbands on one surface of that strip adjacent its longitudinal side edges and cutting the strip transversely to its longitudinal axis to form a succession of individual linings to be applied to spines of a succession of books.
Abstract: A fusible link is provided in a force transmitting device. Upon reaching a preselected temperature, the fusible link melts causing a cooperating locking member to engage a shoulder on a power piston to secure the same in an extended operating position and effect a lock-open condition for certain critical applications.

Abstract: A connector block for mounting a blasting cap and detonating cord in intimate side-by-side association and having an elongated body with a longitudinally extending slot for receiving a signal transmitting shock tube and an elongated cavity for receiving the blasting cap above the shock tube, a knob chock on the forward end of the body for receiving a loop of the flexible tube and a pair of opposed upstanding cleat extensions for receiving a detonating cord and connecting a free end of the detonating cord to the connector block.
Abstract: Combined copying and printing apparatus is provided by combining a known office copier of the plain paper transfer type with a non-impact printer that uses a black on white cathode ray tube optical display to form a latent electrostatic image on the photoreceptor of the copier apparatus. The cathode ray tube may be fixed or movable, as required, and is of the single sweep type using fiber optics to transmit the optical image to the photoreceptor, which photoreceptor moves relative to the CRT sweep to provide a two-dimensional image that is developed and transferred to plain paper. The non-impact printer of the invention can be used as a stand-alone device without provision for the copying function.
Abstract: A connector is disclosed which features a bifurcated contact providing a pair of contact legs enveloped within an insulating body or housing having a conductor entry opening registering with the contact legs. The housing includes beveled cam shoulders adjacent its opening and which cooperate with the contact legs to automatically apply a predetermined conductor locking force upon inserting the conductor into the housing between the contact legs and which increase the locking force in response to a conductor withdrawal force being applied.
Abstract: A system and method for monitoring the concentration of micron size pollutants in a gas, such as sulphate aerosols in the ambient air. The gas is drawn through a dichotomous sampler which segregates the larger aerosols from the smaller ones. The smaller sized particles of aerosols are concentrated and then flowed through an inspection chamber having a plurality of optical windows. The sample is illuminated by the light beam from a laser, and a plurality of mirrors provide a light trap to redirect the laser radiation to the sample a large number of times. The Raman scattered radiation from the particles is collected by a mirror and by a lens onto a spectrograph which provides spectrally dispersed radiation according to the molecular constituents of the sample. This radiation is detected and converted to electrical signals providing qualitative and quantitative information as to the pollutant composition and concentration.
