Abstract: ORAL HYGIENE METHODS AND APPARATUS                     ABSTRACT         Oral hygiene methods and apparatus for producing a liquid jet by pumping liquid through an inlet in a pump housing from a reservoir employ an arrangement in which the reservoir in an inverted position serves also as a cover for the pump housing or inlet.  For optimum compactness, the inlet is provided laterally at the pump housing.  In particular, the inlet may be located in a side wall laterally of a part of the pump housing serving as a first supporting base in an upright position thereof, and the pump housing has a second supporting base laterally of the first base.  In practice, the pump housing is laid on its side or second supporting base, whereby the inlet comes to face upwardly.  Liquid is then pumped from the reapplied reservoir while the pump housing is lying on its side.

Abstract: COMMUNICATION LINE INTERFACE FOR CONTROLLING DATA INFORMATION HAVING DIFFERING TRANSMISSION CHARACTERISTICS Abstract of the Disclosure There is disclosed an office communication system adapted to handle both bursty and continuous data transmission over a single transmission facility to a central switching network.  A programmable station controller is used at each station location to interface a number of transmission inputs to the single communication link.  The programmable station controller is arranged to statistically multiplex the inputs associated with the bursty data while allowing the continuous data to pass on dedicated time slots.  Transmission compatibility between the types of data transmission received from the bursty and continuous data inputs is assured by subdividing the transmission on the single link into frames having four time slots.  A fixed number of time slots of each frame are assigned by a central controller to active ones of the continuous data inputs while other time slots of each frame are assigned to the multiplexed bursty data inputs.  One of the time slots of each frame is utilized for communicating control information between the programmable station controller and the central switching network controller.

Abstract: Abstract of the Disclosure In accordance with the present invention a tractor operated hitch is provided including a vertical strut and a diagonal strut, each connected to the hitch head and which provide the sole support for the hitch head.  A bumper block assembly is pivotably mounted about the hitch head which depends from and extends outwardly from the hitch head in a direction away from the diagonal strut a distance sufficient to locate a bumper within the induRtry standard distance above the deck.  On the opposite side of its pivot point the bumper block assembly is connected to a diagonal strut linkage which, upon application of sufficient force by the tractor to the bumper, will pivot the bumper bloch; assembly about its pivot point and disconnect the diagonal strut linkage from an upright, engaged position t:o a retracted position on the deck.  The vertical strut is provided with a bumper block assembly slot located between transversely spaced vertical legs or in a transverse wall portion whereby in retracted position the hitch and the bumper block assembly do not extend more than six (6) inches above the deck. This allows other tractors and trailers to pass over the retracted hitch and complies with the inudstry standard concerning tractor operated hitches in the retracted position.  Since bending loads are substantially eliminated from thevertical strut, the vertical strut can be made of thinner, lighter material.
