Abstract: An archery bow design in which a pair of flexible limbs are secured on opposite ends of a riser that defines a hand grip or handle, and wherein recoil assemblies at opposite ends of the riser are connected with a bow string to bias the string in a first direction for propelling an arrow. In one form of the invention, a recoil cable extends from the free end of each limb to a cam at the opposite end of the riser, and the cam is connected for rotation with a take-up spool for storing cable. The bow string is connected with the take-up spool, whereby the take-up spool is rotated when the bow string is drawn, thereby rotating the cam and deflecting the limb to store energy for propelling an arrow. In another form of the invention, the recoil cables are omitted and flat wound coil springs are connected with the cam so that when the bow string is drawn the flat wound coil springs store energy.

Abstract: A cylinder head for an internal combustion engine has a substantially greater height than conventional cylinder heads, and intake and exhaust ports which extend angularly upwardly in the head from the combustion chamber to a respective surface of the head. Intake and exhaust valves are provided in the head for controlling flow through the intake and exhaust ports, and the valves are tilted both longitudinally and laterally with respect to the head. The intake and exhaust ports are skewed in the head to closely align the axes of the ports with the angle of the respective valves. Valve operating components are recessed into the top surface of the head, enabling a flat valve cover to be used for enclosing the valve operating components. The invention is particularly directed to a cylinder head having a generally wedge-shaped combustion chamber, and the height of the head in a specific construction is about six inches, with the intake ports angled upwardly at about 30.degree.

Abstract: A condition responsive sending and indicating unit for sensing a condition and transmitting a signal representative of the sensed condition to an indicator at a remote location. The sending unit includes indicia for giving an indication of the sensed condition at the site of the unit, and has a movable contact operatively associated with a variable resistor in circuit with the remote indicator, whereby a variable signal is produced in response to variation in the sensed condition. Calibration of the unit is accomplished by adjustment of the set point of the movable means, and by adjustment of the position of the resistor relative to the movable contact.

Abstract: A fluid actuator including a pair of hingedly interconnected members between which is located a fluid expansible element such as a bellows which may be expanded upon application of fluid pressure to cause pivotal movement of the hingedly interconnected members. The actuator may also include a further pair of hingedly interconnected members which are themselves hinged to the first pair of members and which define with the first pair of members a space for receipt of the fluid expansible element.

Abstract: This invention provides a process for recovery of oil from non-oleophilic areas and surfaces such as rocks, beaches and shorelines by the use of hand-held vacuum nozzles connected to flexible tubing conveying the recovered oil to a first vessel from which the oil is transferred under pressure to a second vessel serving as a storage and transfer vessel to a third vessel which takes the oil to a recovery facility.

Abstract: A spare tire and wheel support and holding structure for attachment to the undersurface of a conventional type trailer structure. A mounting frame for attachment to the trailer has a pair of depending plates, with the free ends of said plates being provided with apertures therethrough near the free ends thereof. A tire and wheel support fixture comprising a frame of U-shaped configuration is sized so that the open ends of said U can pass through the respective apertures at the ends of the depending plates. Quick release pins then retain said U-shaped support frame in pivotal relationship with the mounting frame, the other end of the U-shaped support fixture having hooks thereon for association with a T-bar which is adjustably mounted at the end of a rod pivotally affixed to quick release structure for mounting on another portion of the trailer structure.

Abstract: An ostomy bag holder and cover of lightweight fabric material, comprises a waist encircling belt adapted to be adjustably secured about the waist of the user, and a pouch secured to the belt for holding and covering an ostomy bag, said pouch comprising a back panel having a cut-out therein for providing access from an ostomy bag to a stoma, and a front panel having releasable fastening means thereon for releasably attaching the front panel to the belt for covering an ostomy bag supported in the pouch. The front and back panels define a pocket at their lower ends for supporting the ostomy bag.

Abstract: A push feed system for feeding articles from one position to another, and particularly for feeding pieces to be cut to a jump saw, includes a computer-controlled drive means having a stepper motor connected to drive a double sided toothed belt in engagement with a toothed rack, whereby operation of the belt causes relative movement between the belt and the rack, and a push bar connected to be driven by the drive means. The double sided toothed belt ensures transmission of a large amount of power without slippage, and the computer is programmed to correct for minor differences between a selected cut length and a measured cut length as might be caused, for example, by the dimension of material removed by the saw. A shock absorber is positioned between the push bar and the drive means to absorb impacts between the push bar and stationary pieces.

Abstract: The alkylangelicins according to the invention are obtained starting from an umbelliferone, in which the 6-position is already substituted by an alkyl group; in such a way the 7-allyloxy or 7-acyloxy umbelliferone intermediates can form by transposition of the allyl or acyl group only the 8-allyl and 8-acyl derivatives, and therefore the presence, even in traces, of psoralens is absolutely excluded in the subsequent synthetic steps.The 6-alkylangelicins thus obtained are particularly usable for the photochemotherapy of psoriasys and of other skin diseases characterized by cellular hyperproliferation, as well as for the photochemotherapy of vitiligo and of alopecia aerata.

Abstract: An axial split-pin tumbler lock having a rotatable operating element and a fixed element configured to define a shear plane therebetween, and wherein aligned bores extend in the two elements on opposite sides of the shear plane, with specially configured code pins and drive pins slidable in the bores in the elements across the shear plane, the specially configured code and drive pins being so constructed that they will bind or hang up in the respective bores in any number of axial positions during an attempt to pick the lock, thereby giving multiple and differing false readings of an unlocked condition of the lock and rendering it pick resistant.

Abstract: A bread moulder has a feed chute for receiving dough pieces and directing them between counter-rotating sheeting rollers for flattening the dough and delivering it to apparatus for working it between convergent runs of driven endless upper and lower belts. A shutter is hinged in the feed chute and is biased to closed position but is yieldable under impact of a dough pieces thrown onto it to allow the dough piece to pass through the feed chute. A safety gate in the form of a double grille, V-shaped in end view, is hinged to the feed chute and is movable by a handle to cause its leading part to move the shutter into the chute to dislodge any dough lodged therein, its trailing part forming a barrier before the sheeting rollers.

Abstract: A bread moulder has a feed chute for receiving dough pieces and directing them between counter-rotating sheeting rollers for flattening the dough and directing them between convergent runs of driven endless upper and lower belts. At the sides of the feed chute are feed tubes aligned to receive elongated fingers of dough endwise and to direct them gravitationally between the sheeting rollers to be delivered to and wound spirally by the upper and lower belts for the production of shell rolls.
