摘要:
A mechanism for feeding rod-like articles into a pneumatic conveyor system, comprising rotatable drum means provided with a vacuum assist for receiving rod-like articles from a reservoir and delivering the articles one by one to a fixed receiver chamber within the drum means and connected to the conveyor system; and the receiver chamber being connected to a source of pressure air for propelling the article from the chamber into the conveyor system while providing a source of pressure air for the system.
摘要:
Apparatus for automatic defrosting of refrigerators in which defrosting is commenced on a predetermined time basis and return to refrigeration is initiated on reaching a predetermined temperature. The highest desired defrosting temperature is sensed and circuit means responds thereto to disconnect the defrosting heater and start the compressor. The fan is started after a desired refrigeration temperature is reached.
摘要:
A tobacco feeding device comprising a passage formed by a series of sections consecutively decreasing in cross-sectional area with means at each section for advancing the tobacco along the passage towards the low cross-sectional area end thereof.
摘要:
Means for continuously monitoring the operation of a weld line ultrasonic inspection system to verify that shear wave ultrasonic inspection is being performed and to provide an alarm in the event that ultrasonic energy is not incident on the weld line being inspected.
摘要:
An automatic work handling and/or performing machine responsive to a recorded program having multiple recording mediums for said program and the capability to transcribe one or more copies of said program from one recording medium onto another. Provision is made for varying the playback speed of said one medium during such transcribing or COPY mode while constraining said machine to execute said programmed work cycle recorded thereon and to respond to said speed variations while maintaining a constant recording speed on said other medium. The resulting transcribed program is modified by compression and expansion of portions of said program data thereon in direct response to the said speed variations to provide a program of the selectively modified work cycle. The transcribed modified program can then be utilized to produce transcribed copies thereof on yet another recording medium, thereby precluding the need to completely reprogram a less than optimum work cycle and providing the capability to optimize a previously programmed work cycle.
摘要:
The temperature and moisture content of particulate material, especially tobacco, are adjusted to desired levels by contacting the material with a flow of air having a temperature and relative humidity which would be in equilibrium with the particulate material at said desired temperature and moisture content. A suitable apparatus for carrying out the process comprises a spiral tray for supporting the particulate material, which tray can be oscillated with an upward and rotatory motion so that the particulate material progresses up the spiral to an outlet. Means are provided for circulating air through the spiral and for adjusting the temperature and relative humidity thereof.
摘要:
Microporous films are produced by a process of quenching a polymer solution cast in a quench bath containing a non-solvent system for the polymer to form micropores in the resulting polymer film.

The U-shaped clips which connect the exerciser tension elements to the handles are further secured to the handles by eyelets on the clips, a wire clip extending through the eyelets, and detents on the handles for the wire clip.
摘要:
A pneumatic tobacco feed system comprising a plurality of automatically operated two-way pneumatic switch valves serially connected with each other on the main feed duct, and further individually connected to the discharge units of each utilizing machine, which in turn are manifolded to a suction source. The said valves are automatically pneumatically switched from a first position in which they opens the communication between their inputs and the discharge units, closing the communication to the main feed duct, to a second position in which they close the communication to the discharge unit opening the communication with the main feed duct.
摘要:
A motor assembly and casing is provided in which the assembled parts are pre-aligned on a guide boss on the casing, the guide boss acting to couple the motor to a cased gear train to effect a predetermined alignment between a motor output pinion concentric with the guide boss and the input drive pinion of the gear train. The top of the casing has an internal centrally disposed index peg which interfits with the central stator core of the motor such that when the cover is secured to the casing the predetermined alignment of the motor parts with the guide boss is maintained.
