Patent number: 4189115Abstract: The end of an auto-loading magnetic tape for a computer magnetic tape device is formed in a loop with the magnetized side thereof bent to face outwardly. The length of the bent portion is equivalent to between half and twice the square root value of the product of the radius of a file reel and the spare radial length of the reel radius. The loop is so constructed that the extreme end of the magnetic tape is bonded to the base side of the magnetic tape. The end of the magnetic tape thus offers higher air resistance than the other parts of the tape to the air flow in the cartridge containing the magnetic tape, thereby enhancing the chance of success in a tape auto-loading operation.Type: GrantFiled: July 21, 1977Date of Patent: February 19, 1980Assignee: Hitachi, Ltd.Inventor: Yoshihisa Suzuki

Patent number: 4188866Abstract: A patty broiler has a frame on which an openwork patty conveyor is arranged around pulleys to have an upper run and a lower run. Heaters are arranged on the frame above and below the upper run, and multiple reflectors are arranged on the frame above and below the conveyor. A doctor assists in dislodging patties from the far end of the upper run of the conveyor to fall onto a patty slide on the frame leading the patties by gravity toward the feed end of the frame. A bun conveyor is arranged on the frame beneath the patty conveyor. A bun heater transmits heat to buns on that conveyor and to the patty slide. The warmed bun halves are returned toward the feed end of the machine by a bun slide. An enclosing and vented jacket assists in retaining and diverting the heat and fumes and protects the machinery.Type: GrantFiled: June 16, 1977Date of Patent: February 19, 1980Assignee: NPI CorporationInventors: Edward D. Baker, Nils Lang-Ree, John S. Brown

Patent number: 4188867Abstract: A toaster/oven having a door and a door frame and door jam peripherally surrounding the cooking chamber front opening. The door is pivotally mounted on two hinge pins, a first hinge pin being received in an opening on one side of the door frame and a second hinge pin being received in a slot on the other side of the door frame. The geometry of the slot and pin position on the door is such that the door is not removable except when in its fully opened position. The toaster/oven also comprises door retention means for selectively holding the door in a closed, partially open broil and a fully opened position. The pivotal movement of a lever arm operates first and second switch means which respectively cut off power to the heating elements of the toaster/oven and provide a signal to the controls of the toaster/oven when the door is open.Type: GrantFiled: January 8, 1979Date of Patent: February 19, 1980Assignee: General Electric CompanyInventor: Harold A.

Patent number: 4189237Abstract: A method of mixing concrete and containers for providing predetermined quantities of cement and aggregate to be transported to a site for on site mixing of concrete. The containers have two compartments which are self closing due to the weight of the contents, one compartment containing cement and the other aggregate. When placed on a ring-like support the compartments move relatively to release their contents. The hopper of the concrete mixer has a ring-like support to open the containers and has a water spray curtain to prevent the fine cement powder to be taken away by the wind, with the water spray providing the correct amount of water for the concrete.Type: GrantFiled: January 15, 1979Date of Patent: February 19, 1980Inventor: Willem J. H. Bake

Patent number: 4182472Abstract: A guide for contactless support of a running web as the latter changes directions. The guide is formed as a drum-like member having an arcuately curved surface which can be variable as to the length of its arc depending on the degree of turn or change of direction desired for the running web. A series of parallel grooves are formed in the arcuate surface of the drum-like member, which grooves extend in the direction of web travel. An air nozzle extends along the length of the drum-like member and at each end of the grooves in the drum-like member and pressurized air is fed through the nozzles so as to form a pneumatic cushion between the web and the arcuate surface of the drum-like member to thereby float the web in its turning direction over the drum-like member and without contact therewith. The grooves in the arcuate surface act as labyrinth seals in inhibiting transverse air flow out of the cushion and towards the edges of the running web.Type: GrantFiled: July 13, 1978Date of Patent: January 8, 1980Assignee: W. R. Grace & Co.Inventor: Andres Peekna
