Title: Cleaning method
IPC: B08B9/032
Filed: 1971-12-21
Abstract: 1376150 Cleaning/disinfecting pipework installations DE DANSKE MEJERIERS MASKINFABRIK AmsA 21 Dec 1971 [23 Dec 1970] 59378/71 Heading F2N Plant arranged in a fluid-conveying circuit, e.g. dairy installations for treating/conveying milk, is cleaned by circulating a flushing fluid through the circuit and adding to this fluid a cleaning concentrate for a period of time at least sufficient for all the fluid in the circuit to pass a certain point of the circuit, so that the ratio of fluid to concentrate tends to become constant throughout the circuit. The apparatus shown is for supplying fluid to and receiving exhausted fluid from a selected one of three circuits I, II or III (not shown). As shown, selection valves f connect circuit III between supply line e 1  and return line 15. Water is supplied to a tank 1, under the control of either one of level devices 2 and 3, and from thence via lines 5 and 6, pump 7, line 9, heat exchanger e, line e 1  circuit III, return pump 16, lines e 2  and 8 and valve a to a drain. After a certain time of cold flushing, steam is introduced via valve g to the heat exchanger to heat the flushing fluid in line e 1 . Valve g is controlled by a thermostat 19. Valve a is operated to recirculate the fluid rather than pass it to a drain. Cleaning concentrate is introduced from apparatus 10. When the flushing fluid containing cleaning concentrate has been circulated for a certain time, valve a is re-connected to drain to exhaust the cleaning concentrate after which disinfecting concentrate is introduced from apparatus 11 for a suitable time. The disinfecting fluid may either be recirculated or passed to the drain. Finally, the supply of steam to heat exchanger e is cut off and the system is cold flushed. If the circuit to be cleaned includes a tank, then tank 1 may be by-passed during the recirculating cycles. If the circuit includes only pipework, return pump 16 need not be operated. The concentrateintroducing apparatus 10, 11 may include a reciprocating pump, Fig. 2 (not shown), worked by compressed air fed to the pump in pulses via a valve controlled by an impulse generator, e.g. an astable multivibrator, Fig. 5 (not shown).

Abstract: 1245655 Super-conducting cables SIEMENS AG 20 Dec 1968 [20 Dec 1967] 60860/68 Headings H1A and A4D A super-conducting cable comprises two conductors mutually insulated by a first stream of helium (liquid or gaseous) and cooled by a second stream of helium at a different pressure. The conductors 1, 4 may be concentrically arranged and consist of a thin layer of niobium on a foil of aluminium on a respective inner or outer support tube of aluminium, copper or lead. They are separated from each other either by a helically coiled coil of plastics filament (3) e.g. polytetrafluoroethylene Figs. 1, 2 (not shown), or a series of frusto-conical plastics spacers 13 which are apertured at 14 for the passage of the insulating helium and have slots (15) to allow them to be pushed sideways on to the inner conductor. Cooling helium flows within the inner conductor and outside the outer conductor. In another form Fig. 6 (not shown), three conductors (41) are arranged concentrically with respective tubes (43) of insulating or poorly conductive material, which are separated by a star-shaped spacer (46) and are bound together by straps (45). The conductors are separated from the tubes by spacers such as in the previous arrangements. Several conductors of any of the above forms may be arranged within an aluminium tube 22 surrounded by thermal insulation 23, 26 with an intervening aluminium shield 24 cooled by tubes 25 containing liquid nitrogen. The unit so formed is suspended by filaments 30 within a concrete tube 27 which is then evacuated.

Title: Emergency head unload system for magnetic disk drive
IPC: G11B5/54
Filed: 1979-07-18
Abstract: A magnetic disk drive 10 includes heads 28, 30 on head support arms 24, 26 which are radially positioned by a coil 32. In an emergency, signalled on line 62, circuit 70 supplies dynamic braking of coil 32 via line 76. Relay 50 then changes over and circuit 70 provides a constant velocity control signal via line 78 to retract the heads at a constant speed. When an unload ramp 40, 42, 44 is reached the higher current requirement is sensed by sensor 68 and via line 82 circuit 70 is controlled to provide a higher voltage to coil 32 to enable full retraction. Capacitor 72 provides power in the event of supply failure. The system does not apply the full potential of capacitor 72 to the coil 32 which might result in high acceleration of the heads and damage when the ramp 40, 42, 44 is reached. <IMAGE>

Title: Measured quantities of dispensing lubricant
IPC: F16N37/00
Filed: 1979-09-25
Abstract: This application discloses a material metering device and method for repetitively charging consistently accurate quantity charges of a lubricant retaining and wicking material to lubricant reservoirs of dynamoelectric machine bearings. A metering head 92 is movably supported on a base for motion toward and away from a bearing 86 and its support while both are held in alignment with the metering head.

A valving arrangement interrupts the supply of material without substantially changing either the volume or pressure of the material in the dispensing chamber. An outlet flow path 57 from the chamber to the bearing support structure or other workpiece is established and the material is extruded from the chamber. A metering block 48 is rotatable within a body 22, relative rotation of the block 48 and body 22 operating the valving arrangement. Alternative rotary valve arrangements are disclosed. <IMAGE>

Title: Expanded pet food product and method of producing same
IPC: A23K1/00
Filed: 1979-11-26
Abstract: An expanded pet food product having a moisture content of about 20%-30% by weight and a spongy, compressible cellular structure is made by combining a mix of dry ingredients containing farinaceous materials, proteinaceous materials and dry bacteriostatic materials with a blend of liquid ingredients containing an edible acid, a liquified fat or oil, a liquid bacteriostatic agent and water, and passing said admixture into an expander where it is subjected to mechanical work, shear, heat and pressure. The hot admixture is extruded through a die plate into a zone of lower pressure to cause the extrudate to expand. As the extrudate passes through the die plate it is cut into particles of desired length and promptly contacted with a water spray to reduce its temperature and control the amount of moisture loss from the particles. The cooled extrudate particles are coated first with an edible fat or oil and then with a solution containing an antimycotic agent, water and flavoring material. The thus coated product is then packaged.
