Title: Prefabricated double layer furnace insulation panels - for rapid installation and relief of differential expansion
Inventor: LUFF DONALD GEORGE
IPC: F27D1/14
Filed: 1976-10-22
Abstract: Thermal insulation comprising prefabricated assemblies of superimposed slabs of two different insulating material. One layer is of material with sufficient heat resistance to lie directly against the surface of an oven or furnace, the other material may be of lower performance because of the protection afforded by the first layer. The layers are coupled by belts which may also be used to fix the assemblies to the supporting surface. Panels are used for cladding furnaces with insulation comprising e.g. an inner layer heat resistant up to 1232 degrees C (Als ilica fibres) and a (cheaper) outer layer resistant up to 649-1038 degrees C e.g. mineral wools. Preassembly of the two two complementary layers speeds overall oven/insulation erection, compared with traditional procedures of applying the layers independently and successively.

Title: Banknote checking logic network - is for photoelectric sheet size monitoring and checks each sheet against master pattern
Inventor: KROCHMANN EDUARD DR ING
IPC: G07D7/12
Filed: 1977-01-07
Abstract: A logic network is for use with a photoelectrically based monitoring equipment for testing the size of flat workpieces, typically documents and banknotes. Each sample is checked against a master pattern, and error outside defined tolerances is detected as in 2650706. The sample and master patterns or document pass in front of a photocell monitor and produce slightly different length and offset signal outputs. The differences in durations, starting and finishing points of these signals must lie within some defined tolerances, and equations for these are developed. The monitoring network comprises sets of AND gates which produce sequenced outputs in response to the master pattern and sample pattern inputs. These outputs are fed to a comparator unit which contains a similar set of AND gates and the outputs from this network indicate whether any of the allowed difference tolerances have been exceeded.

Inventor: PLUMLEE KARL W
IPC: C10G1/08
Filed: 1977-05-16
Abstract: Coal is liquefied to produce petroleum-like liq. prods. by (a) mixing particulate coal, a non-donor solvent (I), and a quinone cpd. to form a slurry, (b) contacting the slurry with molecular hydrogen in a liquefaction zone at elevated temps. and press., (c) sepg. the liq. prod. effluent into fractions, including (I), and (d) recycling (I), without hydrogenation to step (a).

Title: Continuous disintegration of microorganic cellular structure - esp. of yeasts, by gas saturation and constriction (CS 29.7.77)
Inventor: RAKITIN VLADIMIR JUREVITSCH
IPC: C12N1/06
Filed: 1977-07-21
Abstract: The micro-organic cells of yeasts, bacteria and fungi are disintegrated in a continuous process, by constricting the watery suspension of cells to bring about their destruction. The aq. suspension of the cells of micro-organisms is satd. with a gas at a controlled press. so that at least some of the gas is dissolved. The suspension is maintained for a period at this saturation press. so that the distribution throughout is uniform, and the suspension is then passed through the battery of disintegrators. The passage through narrow slits in these devices brings about an abrupt fall in press. so that the internal press. of the cells bursts out destroying their sheaths. The plant can be used for obtaining disintegration from the cells which improve digestion and cut out the stages of plasmolysis, as well as the sepg. the intracellular biopolymers such as albumen, ferments, nucleic acids. A hydro-extruder may be used for this disintegration. The loads are detented in stages and the capacity of the plant is 10m3/h. The plant requires high investment costs and has a high energy consumption. With single stage detenting the disintegration is not satisfactory. Disintegration is also carried out in ball mills with corundum, glass or other balls 0.5-0.75 mm dia. The prodn. of this plant is very low and energy requirements are very high. A further process uses two thick-walled vessels in tandem and gas press. of 100-120 atm. This also has a complicated design and a low output. These difficulties are overcome by a disintegrator battery.

Title: Heart beat rate monitor - has upper and lower limits stored in memory and provides indication to wearer when these are exceeded
Inventor: GOMBRICH PETER PAUL
IPC: A61B5/024
Filed: 1978-04-10
Abstract: The heart beat rate monitor has a memory for storing upper and lower limits of a range of heart beat rates. The limits are transmitted to and stored in the memory from an external source. The monitor wearer's heart beat is sensed and whenever the sensed beat rate is outside the range defined by the limits an out-of-range indication is provided to the wearer. The memory is powered so as not to be affected by the depletion of the main battery which is the primary source of power for the monitor circuitry. The limits received from the external unit are transmitted to it for vertification purposes. The actual sensed heart beat rate and/or the stored limits may be displayable to the wearer upon request.
