Abstract: Bees are maintained and bred within a bee compound unit comprising a plurality of compartments that surround and are connected to a central assembly chamber associated with a feeding chamber. Each of the compartments is adapted to house a swarm of bees and one queen bee. Accordingly, bees in an individual compartment are only indirectly accessible to bees in another compartment via the central chamber and can move from one compartment to another only after congregating in the assembly chamber in order to gain access to the feeding chamber associated with the assembly chamber. The bees in all of the compartments can be cared for and treated only in one of the compartments by removing combs with swarming bees from the one compartment and replacing them with empty combs.

Abstract: The free end of an arm rotatable with one hinge member contains a roller receiving cavity which opens to an arcuate friction layer on the other hinge member which is disposed about the axis of relative rotation of the hinge members. A spring biased double faced wedging member is movable into and out of the center of the cavity and each face of the member is respective to a semi-cylindrical roller retention surface of the cavity. One face is more steeply sloped than the other. When the hinge members are in door closed position the less steeply sloped face resiliently holds a cylindrical roller against a roller retention surface and the friction layer. As the hinge members rotate toward door open position, the cylindrical roller rotates along the friction layer, past the less steeply sloped face, and into rolling contact with the other retention surface and friction layer under the bias of the more steeply sloped face.

Abstract: Upon rupture of a thread or the like a thread monitor or stop motion moves about a pivot point in clockwise direction, and thus, by means of a release rod, causes an entrainment element to come into engagement with a to-and-fro driven entrainment member. Consequently, an actuation rod is upwardly moved and latched by a support lever in its upper position. Due to this movement a feed bobbin along with the therewith operatively correlated thread guides are lifted, so that the thread travel path is shifted out of the effective region of a singeing burner. Due to the raising of the feed bobbin there is diminished the spacing between such feed bobbin and a winding bobbin. Due to lifting of the actuation rod the winding bobbin, in response to the operation of a pawl and a tooth segment, is raised from a driving cam or grooved drum. The raised position of the feed bobbin facilitates the knotting of the thread.

Abstract: A tool holder has compliance features that allow a hole to be drilled at high tolerances by a remote controlled control arm. The holes are drilled in a workpiece that has a template secured over it with guide holes for positioning the holes to be drilled. A self-feeding drill of the type that will simultaneously rotate and advance a drill bit is mounted in a support. A sleeve is carried at the forward end of the support for enclosing the drill bit. An index carriage moves the support forwardly into the guide hole after the control arm has substantially aligned the sleeve with the guide hole. Compliance mechanisms in the support allow the entire drill, drill bit and sleeve to move as a unit a limited amount parallel to and angularly with respect to the template and the indexing carriage, to allow advancement of the sleeve into the guide hole even though there may have been initial misalignment. The compliance mechanisms preferably include an inner guide member mounted within an outer guide member.

Abstract: A non-volatile memory structure of the floating gate type is described wherein current carriers are injected onto the floating gate from the control gate as distinguished from the prior art which injects current carriers into the floating gate from the substrate. This invention teaches that by tailoring the capacitance between the control gate and the floating gate and the capacitance between the floating gate and the substrate different field intensities are created in the region between the floating gate and the control gate and in the region between the substrate and the floating gate. When the field intensity across the capacitor formed between the control gate and the floating gate is greater than the field intensity across the capacitor formed between the floating gate and the substrate, current carriers will be injected onto the floating gate from the control gate.
