Abstract: A bread molder for working dough between convergent runs of driven endless roller-mounted upper and lower belts has the lower belt carried by an adjustment frame which can be moved to vary the spacing between the two belts. A pair of side shaping arms can be inserted closely between the two belts to limit the lateral expansion of the dough being worked. A delivery plate on the belt adjustment frame extends below the upper belt to receive and deliver a dough piece worked between the two belts, and a series of spaced parallel splitter blades are mounted for simultaneous advance between divisions in the delivery plate for dividing the worked dough into sections.

Abstract: This box type turkey call is a combination of two calls which share a resonance chamber. The first sounder is elastically engaged to work the arm actuator over the edges of the chamber walls and is pivotally mounted. The second sounder is a stylus with sound tube which is used to scrape the slate on the bottom of the resonance chamber. When not in use the stylus is intended to be mounted through the resonance chamber by placement through a hole in the end wall of the chamber. The two calls may be used together. The presence of one sounder in or on the resonance chamber assists in making appropriate calls.

Abstract: The use of a high solids content medium for preparing cheese starter cultures is effective in conditioning the bacteria to enhance their ability to produce cheese from a high solids base. The ingredients of the medium include carbohydrates which are not fermentable by the bacteria, as well as milk protein sources and conventional nutrients.

Abstract: A modular access flooring system (10) has triangular floor panels (11) supported at the corners by free-standing pedestals (12) which are laid on a base floor. Hemispherical projections (18) on the panels (11) engage in recesses (19) in the pedestals (12) to lock the panels (11) and pedestals (12) together during installation of the system (10), the panels (11) and pedestals (12) determine where the others are to be positioned, obviating the requirement for the pedestals (12) being laid in predetermined patterns. As the panels (11) and pedestals (12) are all supported at three points, the flooring system (10) is very stable and can accommodate any movement in the base floor.

In use, at least one of the hollow cores is opened through the top surface of the beam unit along at least a portion of its length, preferably at a point of high stress where the beam rests on a support, for example.

Abstract: An archery bow design in which at least one flat wound power spring is mounted on a frame and is connected through an eccentric wheel or cam and a pulley system to a bow string so that the action of drawing back the bow string causes the coil spring to be wound up, storing energy. The eccentric wheel or cam and the pulley system provide a mechanical advantage whereby a relatively small force is required to draw the bow and wind up the power spring, and a relatively higher recoil velocity is obtained when the string is released.

The loading panels may be of solid panel construction or of expanded metal, depending upon the type of litter being picked up and the method of use of the apparatus.

Abstract: An agricultural implement having a mobile mounting frame for moving across an area to be treated, and a soil working assembly co-operating with the mounting frame. The soil working assembly includes a flexible chain of interconnected links, the chain being rotatable about its axis and having blades extending from the chain. The blades are adapted to penetrate gravitationally, scoop hollows from, the soil as the implement is advanced rotating the chain over the soil. The implement reduces undesirable consequences of rapid and unimpeded run-off of rain water by upturning the soil in such a manner that run-off is impeded.

Abstract: The tackle box of the invention comprises a support member having structure for securing it to a front portion of the waist of a user, a first receptacle pivotally mounted to the support member and adapted to move between a closed position disposed upwardly against the support member and an open position disposed generally horizontally in front of the support member, and a supplemental cover and shelf member pivotally mounted to the receptacle for movement between a closed position disposed in overlying relationship to the receptacle and an open position disposed generally horizontally in front of the receptacle. A second receptacle is mounted to a front wall of the first receptacle and the contents thereof are accessible without opening the first receptacle, whereby items likely to be chosen more often may be stored in the second receptacle. A plurality of removable rods are frictionally retained to the shelf member for holding flies, hooks and other articles.

Abstract: A fastening bar assembly for connecting together adjacent insulating panels of an insulated enclosure, in which the panels have a foamed in situ insulating foam core and metal skins on the inner and outer faces thereof, and wherein the fastening bar assembly is encapsulated in the foam core and has connecting means on opposite ends thereof for securing together adjacent ends of fastening bar assemblies in adjacent panels. In the present invention, an improved fastening bar assembly comprises an elongate bar body having opposite ends bent at an angle to the body and extending into proximity with a peripheral flange on the skin of the panel and secured to the flange on the skin, whereby in a completed panel the fastening bar serves to strengthen the skin and prevent its delamination from the foam core, and said fastening bar is also accurately positioned in the panel. In addition, an improved panel sealing gasket is secured to a side edge of the panel.

Abstract: The present invention comprises a stair construction and method in which the stair includes at least one stringer assembled in situ from a plurality of stringer units, treads supported on the stringer, and a hand rail comprised of a plurality of hand rail units or sections secured together in situ. The use of modular construction, with the parts assembled in situ on a job site, enables the components to be manufactured in a factory and then shipped in convenient packages to the job site for assembly. This enables relatively complex stair designs, such as spiral and circular stairs, as well as more conventional straight stairs to be employed in construction without concern for bulky and difficult to handle packaging and shipping, or the need for skilled carpenters using special tools to construct such stairs on the job site.
