Title: Engine crank pin rolling equipment, rolling tool and method of rolling adjacent and offset crank pins
Inventor: GOTTSCHALK WILLIAM P
IPC: B24B5/42
Filed: 1994-12-22
Granted: 1999-01-05
Abstract: Arcuately offset pairs of juxtapositioned pin journals of an internal combustion engine crankshaft have  their  fillets  pressure  rolled  for  fatigue strengthening by opposing inclined rollers carried in cages  at  the  lower  ends  of  a  pair  of  relatively rotatable tool housings  supported  in a  side-by-side relationship by a pair of jaws of floating clamping structure.  This structure allows the rollers to follow the crank pin journals as the crankshaft is being turned so  that  arcuately  offset  crank  pin  fillets  can  be simultaneously  pressure  worked   and   strengthened. opposing roller reaction loads are cancelled at load receiving bearings operatively interposed between the pair of tool housings.

Abstract: A milk foaming device for emulsifying steam, milk and air to produce foamed milk.  The milk foaming device includes an ingredient combining assembly for combining the steam, milk and air connected to a swirl chamber for blending the ingredients.  A discharge tube is attached to the swirl chamber for dispensing foamed milk therethrough. A concave notch is formed in the walls of the discharge extending from a dispensing port of the tube upwardly along the walls.  The notch retards or prevents formation of bubble surfaces over the dispensing port of the discharge tube and thereby prevent splattering of milk.  A laminator is provided in the tube for inducing a columnar flow of foamed milk from the discharge tube.

Granted: 2000-05-23
Abstract: A child neat apparatus includes a seat, a reclinable backrest, and at least either a pair of side guards rotatably mounted on the backrest or a pair of armrests mounted on the seat, wherein the, lateral spacing between the side guards or the armrests is changeable. An interlocking mechanism links the backrest with the side guards or the armrests so that the space between the side guards or the armrests is changed in association with the inclination of the backrest.      Specifically, this space is widened as the backrest is reclined. Such an interlocking mechanism, for example, includes driving pins that are driven with an upper end of a bridging bar for supporting the backrest in a reclined state while a pair of driven slots are provided in the side guards for receiving the driving pins respectively. The driven slots are directed at an angle relative to each other so as to be closer to each other at upper ends thereof. Due to this structure, a dimensional allowance is provided around the shoulders of a child When the backrest is reclined into the form of a bed.

Abstract: In an asynchronous transfer mode (ATM) system, interleaved cells are formed at the transmit end by combining into each interleaved cell certain bits from each of plural different original ATM cells, the interleaved cells are transmitted over the communications link, and then deinterleaved at the receive end. Any bursty errors occurring on the communications link will, after deinterleaving, be spread out over multiple original ATM cells, maximizing the error correction for ATM cells and error detection for AAL capability and minimizing loss of data. The C1 byte in the Physical Layer Convergence Protocol (PLCP), which indicates the location of end of the PLCP frame, is protected against the burst errors by replication of C1 byte through inserting them in the growth bytes Z1 through Z4.

Abstract: Horseradish peroxidase (HRP) immobilized on colloidal gold and then deposited on an electrode surface can be reduced at a convenient rate at low voltage (Ag/AgCl) without an electron transfer mediator.  Bioelectrodes combining both a colloidal gold-adsorbed oxidase and colloidal gold-adsorbed HRP located on an electrode surface are efficient biodetectors, particularly for the measurement of low glucose levels in samples when glucose oxidase is employed as the sensing enzyme. The biodetectors may be employed for mediatorless detection if a wide variety of analytes depending on the oxidase employed.

Abstract: A carton transfer assembly having a rotary feeder that rotates a series of selectors about a transfer path between a carton feeder and a transport conveyor. The selectors each include vacuum engagement members adapted to engage a selected carton to remove the selected carton from the carton feeder and carry the carton toward a transpo rt conveyor as the rotary feeder rotates the selectors about the transfer path. Each selector further includes stingers that are operated off of the vacuum applied to the cartons by the vacuum engagement members to move the stingers between extended and retracted positions. As the vacuum is applied to the stingers, the stingers are retracted. When the vacuum is disengaged, the stingers move to an extended position to engage and spread apart the panels of the cartons to open the cartons prior to the deposit of the carton s within the carton pockets of the transport conveyor.

Abstract: Arcing-faults in an electric power distribution system are detected by a circuit which includes a band-pass filter generating a low frequency bandwidth limited arcing current signal having a bandwidth above the measurable harmonics of the ac current but below the frequency band of power line communications systems, about 3 KHz to 20 KHz and preferably about 6 KHz to 12 KHz. For each cycle of the ac current that this low frequency bandwidth limited arcing current exceeds a threshold, preferably related to the amplitude of the ac current, for a selected duration of the cycle, a fixed pulse is generated. If a time attenuated accumulation of these fixed pulses reaches a selected level representative of a number of closely spaced cycles in which the arcing current has been detected for the selected duration, an arc indicative signal is output. Preferably, the value of the time attenuated accumulation of pulses at which the arc indicative signal is generated is variable so that fewer pulses are needed to generate the output as the amplitude of the ac current increases.
