Abstract: A paper-feeding mechanism of a compact printer is provided. The mechanism has a driven wheel which transmits rotation to a paper-feeding roller and a driving wheel which drives the driven wheel. The driving wheel has first and second sets of gear teeth for engagement with teeth on the driven wheel. The driving wheel is axially displaceable to provide for driving with the first set of gear teeth at a normal paper feed rate and also by the second set for driving at a rapid paper feed rate. A solenoid-operated rate-selection lever serves to select either of the driving speeds. A cam attached to a power wheel which drives the driving wheel serves to return the mechanism from rapid to regular paper-feeding.

Conductive leads are covered, at least in part, by an insulating film.

Abstract: The strong sexual excitants emitted by female animals when in heat and which serve to attract and arouse the male to mate are destroyed by treating with compounds containing chlorine dioxide in stable form. The compounds are non-irritating and are sufficiently effective when applied externally or internally so that a female in heat can be brought near a male of the same species without causing any appreciable change in the behavior of the male.

Abstract: A therapeutic preparation of a bacterial component (designated as OEP and formally as CWP) derived from Pseudomonas aeruginosa possesses vaccine activity (the effective component being a lipoprotein of Pseudomonas aeruginosa) or the same containing antibiotics is effective in the treatment of mink hemorrhagic pneumonitis and bovine mastitis due to Pseudomonas aeruginosa.

Abstract: Manually-prepared art work including indicia, art compositions, instructional material and decorative material in a wide variety of colors are prepared through the use of markers of the felt-tipped variety and inks compounded to be applicable by said markers. The inks contain volatile, dispersible dyes, and manually-prepared material in the form of compositions on appropriate paper is transferred to appropriate fabric by the application of heat and pressure. The fabrics are those which will accept volatile, dispersible dyes.

The intermediate concave lens is positioned so that it contacts at the front surface thereof with the rear surface of the objective lens and so as to align the optical axis thereof with that of the objective lens.

Abstract: A camera mechanism provides for motion of a metal component relative to an njection-molded plastic component. The parts are so formed that contraction of the plastic subsequent to injection-molding grips the metal component tightly enough to hold said components in fixed position relative to each other so far as accidental relative displacement is concerned, while permitting relative motion when enough force is applied to overcome the frictional resistance threbetween. The mechanism is particularly suitable for use in focussing the camera, that is, changing the distance between the lens housing and the film plane.

Abstract: A positive cam lock for a pair of telescoping extension poles. The cam support is mounted to the inner pole and carries a coaxially rotatably mounted idler cam and an eccentrically rotatably mounted locking cam. The outer pole has a number of inwardly extending splines which engage corresponding grooves on the locking and idler cams. When the outer pole is rotated, the eccentric cam will rotate and lock the outer pole at a desired axial position with respect to the inner pole while the idler cam prevents misalignment. A key mounted to the locking cam rides in a keyway on the cam support for preventing over-rotation of the locking cam.
