Title: Band clip with screw thread - has single piece housing and tightening band with free end pulled through by screw
Inventor: RASMUSSEN JOERGEN
IPC: F16L33/08
Filed: 1975-02-17
Abstract: The clip is for hoses and pipes and has a tightening screw turning in a housing with U-shaped cross section and the edges turned inwards. The design overcomes the problem that galvanised parts of the housing are difficult to weld and the spot welding is not always satisfactory. The band (1) and the housing (2) are designed as a single component, with the free end of the band locating in the housing. The housing wall has a stiffening section (7, 8) and the underside band is held in position by tangs that bend over a flat under-section. The tightening screw is supported at its end by one end face of the housing and at a recess, below the screw head, by a rim on the open end of the housing.

Title: Electronic coin tester with logic circuit - has two or more probes, test circuits switches consecutively excited by coin
IPC: G07D5/00
Filed: 1975-03-13
Abstract: The electronic coin tester has two or more probes, test circuits and switches which are consecutively excited by a coin. A logic circuit connects the GOOD decision of a first test station with the GOOD decision of the last station, reached by teh coin in its normal travel. When the decisions of all test stations are good, the coin is accepted by a counting pulse and/or operation of a sorting gate. IF a GOOD decision from the last test station is not preceded by a GOOD decision from the first station, a signal is generated which erases or temporarily puts out of action the used test circuits.

Title: Spray drying of liquid of pasty prods. in two stages - avoiding high temp. and using high partial press. difference
Inventor: JANOSIK MANFRED DIPL ING
IPC: B01D1/18
Filed: 1975-11-06
Abstract: In the drying process, after atomising, the prod. is predried by a carrier gas conveyed by a monofilament band filter, stretching across the entire section of the drying tower at the end remote from prod.-spraying, out of the path of the carrier gas. In a second stage, drying gas with a very low partial press of wet stream is passed through the prod. a variable residence time being used to ensure that the capillary liq. is dried out. Prods. difficult to spray-dry, and/or temp.-sensitive prods. can be treated, at very low operating costs. The particle size, gas temps., and flow rates have only a slight influence on the results. The first phase operates at low partial press. difference, the second phase at higher partial press. differences and variable residence time.

Title: Shaft bearing shell with axial lubricant pockets - is produced by using a mandrel to partially deform bearing shell
Inventor: PIMISKERN KLAUS
IPC: F16C33/14
Filed: 1975-11-21
Abstract: A friction bearing for a rotating shaft has axial recesses (28) which are not in contact with the circular shaft surface (18). Thus the recesses form wedge shaped pockets to produce hydrodynamic pressure points for the lubrication medium. The bearing is produced by forcing a spherical mandrel through the bearing shell which is drilled under-size. By placing the bearing shell inside a bush (20) which gives partial support during the shell deformation, the unsupported bearing areas deflect radially outwards during the passage of the mandrel. The supported areas are deformed and form the oil pocket when the bearing is removed from the support bush.

Title: Isenthalpic refrigeration expansion feed - has feed circuit carrying alternate fluids with varying cooling capacities
Inventor: BYTNIEWSKI JOSEPH
IPC: F25B45/00
Filed: 1976-08-25
Abstract: The design concerns a process to feed small refrigerating machines with isenthalpic expansion. The process is carried out by a single feed line provided in an insulated casing.

Inventor: KNEISSL HANNES DIPL ING
IPC: C10G47/30
Filed: 1977-03-15
Abstract: Coal liquefaction is carried out by (a) slurrying finely divided coal in oil, (b) subjecting the slurry to catalytic hydrotreatment at high pressure and temp. under conditions such that =40% (pref. 5-30, esp. 20%) of the coal is converted to distillate oil, (c) coking the solid-contg. residue, and (d) recycling the heavy and middle distillate oils produced by coking to step (a) for slurrying more coal. Hydrotreatment is pref. effected at 430-485 degrees C and 100-300 bar. Coking is pref. effected at 470-600 degrees C and 10 bar, esp. in the presence of added H2 to improve the quality and yield of the by-product oils and convert S contaminants to H2S. The process reduces H2 consumption, allows crude H2 sources (e.g. coke-oven gas) to be used, the facilitates ash sepn. Petroleum residue can also be treated in the process by mixing them with the feed to the coker and/or with the recycle oil.
