Title: Process and apparatus for the treatment of turbid liquids, particularly for the hydrolysis of lactose in whey
Inventor: OTTOFRICKENSTEIN HANS
IPC: A23C21/02
Filed: 1984-03-09
Granted: 1987-02-05
Abstract: A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.

Title: Robot arm
Inventor: RICHTER HANS
IPC: B25J17/00
Filed: 1984-06-07
Granted: 1989-06-22
Abstract: A robot arm consisting of an upper arm link and a lower arm link which are interconnected by a uniaxial joint. The upper arm link is connected with a structure via a universal joint. In order to attain a weight balance, a bellcrank level is placed on the upper arm link, on whose one lever arm an upwardly directed equalizing force acts and whose other lever arm is connected to the lower arm link. If both arm links are in alignment with one another, then the point of application of force on the one lever arm has its greatest distance to the universal joint. If, on the other hand, the lower arm link is swung out of its alignment with the upper arm link, then the distance between the point of application of force and the universal joint is decreased.

Title: Method of monitoring fitting pressure for track links
Inventor: MORIKI YASUMITSU
IPC: B62D55/32
Filed: 1985-07-01
Granted: 1988-06-01
Abstract: Loading pressure in the ram of a track press is compared with both the lower and upper limit pressure values which are prescribed with reference to the range of fitting pressure specified for the links. Fitting of a link is determined acceptable when a sum of the press loading time is longer than a predetermined value while press pressure is maintained within the range between both the lower and upper pressure values. The fitting of the link is determined unacceptable when the sum of press loading time is shorter than the predetermined one or when time in which press pressure exceeds the upper limit pressure is longer than a predetermined time. Excess pressure spearing  within the allowable time during the pushing operation of the track press is neglected.

Abstract: Molded synthetic resin dunnage supports (10) for packing of elongated fragile fluorescent tubes are provided which are designed for automated dispensing during packaging and give protection against tube breakage at least equivalent to that of conventional molded pulp supports. In preferred forms, the dunnage (10) support is formed from polyvinyl chloride sheet material (0.014 inch thickness) and includes plural juxtaposed tube-receiving sockets (24) together with a rear side lip (20) and front side ledge platforms (42); the lip carries laterally spaced upright nibs (50) which, in conjunction with the ledge platforms (42), prevent complete nesting of the supports, so that an interfitted support stack presents substantially even access spaces between individual supports for easy machine dispensing. The tube-receiving sockets (24) are provided with alternating, vertically spaced, upwardly and downwardly opening arcuate, striated tube-engaging sections so that a single support can simultaneously engage and cushion a pair of tube layers in a shipping carton. The dunnage design affords a high degree of protection for the packaged tubes and can safely absorb potentially destructive impacts without tube breakage.
