Abstract: ABSTRACT           A tractor drawn and powered machine is disclosed for forming large round bales of fibrous agricultural crops in a chamber of fixed size.  The baling chamber consists of a lower and an upper section.  The lower section includes a wheel mounted main frame, along with a pickup reel and a bottom conveyor comprising side by side belts entrained on four transversely extending rollers.  The upper section is supported on a subframe which is hinge mounted along its front edge to the main frame allowing thereby the rear por-tion of the upper section to open as a rearward facing tail-gate for discharge of a completed bale.  Situated within the subframe of the upper section are all of the conveying elements which make up the rear, top and front of the gene-rally cylindrical periphery of the baling zone.   Each conveyor element in the upper section comprises a plurality of side by side belts entrained on spaced apart transversely mounted upstream and downstream rollers.  A space between the last of the serially arranged conveying elements and the uppermost surface of the bottom conveyor provides an inlet into the baling chamber.  During the bale forming operation a latch mechanism holds the tailgate closed.  When a bale is ready for discharge the tractor is halted, the tail-gate is opened by a hydraulic cylinder and the bale is con-veyed out the rear of the machine.  As soon as the bale falls to the ground, the tailgate can be reclosed making the machine ready for pickup of more crop material with which to form another bale.

Abstract: ABSTRACT           A brake system for bicycles includes a clasp type rim brake having a stirrup with arms which are resiliently deflectable so as to clasp shoes against opposite sides of the rim of a wheel upon the stirrup being drawn radially outwards, a powerful clasping action being provided by guides in wedging engagement with portions of the stirrup.  The radially outward movement of the stirrup is preferably provided by an actuator operated by a pedal crankshaft of the bicycle, the brake being applied to a rear wheel of the bicycle and a chain drive between the crankshaft and the rear wheel including a lost motion linkage so as to help avoid brake lock-up.  Upon pedalling of the bicycle, the lost motion is taken up against a progressive bias applied by a spring.  The actuator may also operate a front brake being connected to it by a cable having some resilience, whilst being connected to the rear brake by a rigid link.  To further assist in preventing lock-up, the guides may have provision for a limited degree of tangential displacement of the brake stirrup relative to the rim.

Abstract: FIRE DETECTION SYSTEM WITH IR AND UV RATIO DETECTOR            Abstract of the Disclosure An automatic fire detection system characterized by an extremely low incidence of false alarms utilizes two detection channels, one fed by an infrared (IR) detector and the other by an ultraviolet (UV) detector.  Signal processing electronics in each channel produce a normalized output signal proportional to the power of incident IR and UV radiation within specific band-widths.  The system features a ratio detector that repeatedly forms a ratio of the normalized IR and UV inputs and compares the ratio to a known range of values for this ratio that are charac-teristic of a fire.  A discriminator connected to the output of the ratio detector generates a fire alarm signal only if the majority of these ratio comparisons are fire-indicating.  The system also includes a feedback loop in the IR processing channel that automatically adjusts the output of the channel to compen-sate for time-varying background IR radiation such as sunlight.

Abstract: ABSTRACT OF THE DISCLOSURE             In the design of electrical switchboards or control panels or the like there are employed push buttons for the actuation of a switch for performing a desired control function or operation.  There is disclosed a push button containing a solid or rigid front impact flange member and a rear impact cam or detent which is arranged at the tip of a tongue-like spring member or resilient tongue and possesses an inclined guide surface.  The push button can be mounted in the cover plate of an assembled switchboard or control panel or the like, without the  need  for  any auxiliary  tools,  and  is  positively self-retained thereat without there being required access to the rear side of the cover plate or to the interior of the switchboard panel.  A spring-biased support member of a switch arranged rearwardly of the cover plate presses the push button at its rear impact surface against the rear side or face of the cover plate and retains such in the desired rest position.  The push button can be again dismantled, with the aid of extraordi-narily simple means, out of a completely assembled together unit without there being necessitated any access to the rear side of the cover plate.

Abstract: ABSTRACT     A fleshing machine for removing unwanted tissue from an animal pelt.  A longitudinal mandrel holds the pelt and fleshing means include a tissue-removing head moveable longitudinally and trans-versely with respect to the mandrel to remove tissue from the pelt, and a handle for moving the head with respect to the mandrel.  Dual linking means mechanically and hydraulically link the handle to the tissue-removing head for hydraulically moving the head longi-tudinally of the mandrel in response to longitudinal components of movement of the handle with respect to the mandrel and for mechani-cally moving the head generally transversely of the mandrel in response to components of handle movement generally transverse of the longitudinal direction of the mandrel.  The use of the final linking means preserves the "feel" of the fleshing operations but reduces fatigue resulting from movement of the fleshing head longi-tudinally of the mandrel.

Abstract: ABSTRACT OF THE DISCLOSURE          An adapter for connecting a bypass oil filter to an internal combustion engine having a full flow lubricating system mounted between the oil filter mounting block and the conventional full flow filter.  The adapter includes means for diverting a portion of the circulating oil flow to the bypass filter and means for returning that portion to the engine.  The adapter includes a body portion and an insert which together define the passages necessary for diverting a portion of the oil flow to the bypass filter.  The body includes a central axial opening which receives the insert, the body and insert together defining an annular chamber which receives clean oil from the bypass filter through a radial passage in the body.  An axial passage in the insert allows clean oil to flow from the full flow filter to the engine and a plurality of radial passages allow clean oil from the bypass filter to enter the axial passage regardless of the relative orientations of the insert and the body. Additional passages are formed in the body to provide the remaining flow paths necessary for the bypass flow.
