Abstract: A simple and inexpensive plastic assembly snaps over the rim of a toilet bowl. The deodorizer/disinfecting embodiment container hangs outside the toilet bowl. It is supported by a rim clamp inside the toilet bowl. One model simply clips on clips off for disposable use. Other models have a container with a refillable top. An adjustable exit tube nut adjusts to various different toilet rims. When the user sits on the toilet seat, a diaphragm is compressed which forces air into the container and deodorant/disinfectant into the toilet bowl. The diaphragm needs to be made of neoprene or any flexible material with sufficient memory to return to its original non compressed shape after compression.

Abstract: An improved rotor design is provided for an internal batch mixing machine. A rotor has a rotor body with an axially extending central cavity, and with a plurality of mixing wings defined on the outer surface of the rotor body. A plurality of internal reinforcing ribs of generally spiral or curved configuration are defined on the rotor body and project into the cavity.

Abstract: Method and apparatus for programming non-volatile, programmable, electrically-erasable memory using a USB interface are presented. According to one aspect, a method for in-system programming of non-volatile, programmable, electrically erasable device memory using a USB interface includes the steps of: enumerating at least one device onto a USB bus with a first hardware configuration; encapsulating programming commands and program data into USB packets according to a custom protocol; sending the USB packets including the encapsulated programming commands and program data to the at least one device over the USB bus; and programming at least a portion of the device memory in response to receiving the programming commands and program data at the at least one device. At least partial functionality of the at least one device as defined by the first hardware configuration is maintained while the device memory is programmed.
