Title: Vacuum cleaner with improved assembly
Inventor: HAMPTON LEONARD D
IPC: F24F13/20
Filed: 1993-10-06
Abstract: VACUUM CLEANER WITH IMPROVED ASSEMBLY                ABSTRACT OF THE DISCLOSURE     The present invention relates to an upright vacuum cleaner having an improved assembly to optimize the assembly and operational characteristics of the vacuum cleaner.  The floor engaging unit of the vacuum cleaner has a two-piece body including a base and a hood which are snap-fit together.  A motor is rotatably mounted within the body at the end of a handle assembly.  The handle assembly, which also functions as a conduit for dirty air to travel to a disposable filter bag, carries an electrical connector which connects the motor to power.  The handle further provides a stop which engages a hose hook that slidably fits over the top of the handle, the stop being located such that the hose hook is properly positioned to support a hose during storage thereof.  A filter bag, which is mounted to the handle at a location downwardly spaced from the top of the filter bag, is provided with a wire frame to help support the weight of the disposable filter bag. The motor is provided with a foot switch actuator assembly that allows actuation of the motor switch regardless of the radial position of the motor switch.  A brush roller, which is rotatably driven by the motor, includes a pair of mounting end  caps.    The  end  caps  include  outwardly  extending projections which  are  received  by  the  base,  releasably mounting the roller thereto.  The invention reduces the time, labor and material required to manufacture and assemble an upright vacuum cleaner.

IPC: H04H20/95
Filed: 1992-10-20
Abstract: PCT No. PCT/EP92/02401 Sec. 371 Date Apr. 20, 1994 Sec. 102(e) Date Apr. 20, 1994 PCT Filed Oct. 20, 1992 PCT Pub. No. WO93/08656 PCT Pub. Date Apr. 29, 1993.Digitalized encoded audio signals for transmission over disturbed channels are composed of a series of information blocks made of information units containing various types of information, such as control information, scale factor information and information on encoded scanning values derived from partial-band and/or transformation coding at the source. The units of information concerning the encoded scanning values are allocated to a predetermined spectral structure. Before its transmission or storage, the encoded audio signal is subjected to a channel encoding dependent on the desired error protection. When errors are recognized, they are corrected, and when the errors cannot be corrected, they are concealed. For the channel encoding of the units of information concerning the encoded scanning values, a variable bit error protection is provided depending on the allocation of the individual information unit to a determined spectral structure, i.e., units of information concerning the encoded scanning values of lower frequency audio signal fractions are given a higher bit error protection than units of information concerning the encoded scanning values of higher frequency audio signal fractions. The variable error protection to be selected for the individual information units is further determined depending on the admissible duration and frequency, according to subjective criteria, of the applied error concealment.

Title: Vehicle wheel incorporating tire air pressure sensor
Inventor: OLNEY ROSS D
IPC: B60C23/02
Filed: 1993-09-29
Abstract: VEHICLE WHEEL INCORPORATING TIRES AIR PRESSURE SENSOR    ABSTRACT OF THE DISCLOSURE     A tire air pressure sensor  (18)  is mounted on a vehicle wheel (10) and includes an inertial mass (40) which is urged radially outwardly by centrifugal force resulting from rotation of the wheel (10).  The tire air pressure is applied to the inertial mass (40)  in opposition to the centrifugal force.  When the rotational speed of the wheel (10) is sufficient that the centrifugal force overcomes the applied air pressure, the inertial mass (40) moves radially outwardly and opens a switch (33).  The speed at which the switch (33) opens is a predetermined function of the tire pressure.   In another embodiment (130), a second sensor (154,160) is provided to sense when the tire pressure is below a minimum value.  A spring (140) urges an inertial mass (138) inwardly in opposition to the centrifugal force, and the tire pressure is applied to a bellows (154) having an end (160) which moves radially outwardly in proportion to the applied pressure.  The bellows (154) opens a first switch (166) when the pressure is higher than the minimum value, and the inertial mass (138) moves radially outwardly away from the end (160) of the bellows (154) to open a second switch (168) when the wheel speed exceeds the value corresponding to the tire pressure.
