Patent NL-7411700-A (NL)
Title: New method of fire detection in mines - obtains continuous measurement of carbon dioxide concentration gives alarm when given value is exceeded
IPC: G08B17/117
Filed: 1974-09-03
Abstract: Continuous measurement of carbon dioxide concentration is made. When the measurements indicate a predetermined concentration has been exceeded an alarm is given. The alarm is also given when the gas concentration rate of change exceeds a predetermined value. The alarm system is actuated by sensitive detection which respond when gas concentration exceeds the predetermined value, and when the rate of change of gas concentration exceeds a predetermined value. The method works on the principle that the carbon dioxide gas concentration in the mine atmosphere increases very rapidly during the initial stages of a fire.

Title: Rotary silo top discharge mechanism - has several driven cutters mounted at intervals along one or more drive arms
IPC: A01F25/20
Filed: 1976-08-03
Abstract: The rotary silo top discharge mechanism has a number of driven cutters (5).

Title: Press for mfg. granular material - has cylindrical matrix with cooperating pressure roller, protruding pins and grooved formation
IPC: B30B11/20
Filed: 1982-08-31

Date Nov. 28, 1991.A data packet transmission system having a succession of stations each connected to two buses transmitting in opposite directions, both packets and time-slot requests has its capacity improved by means of a request-erase counter at each station for each bus, making possible more efficient use of time slots. Except for the different combinations of status and expectable occurrence, the queuing protocol known as DQDB, optionally is modified by D3Q protocol, is used. For those ten situations where time-slot-request bit resetting (erasing) comes into play, status is defined by the state of certain counters while expectable occurrences are arrivals at a station's access unit of a time-slot that is empty or contains a data packet or a request bit and also the use, if any, made of the arriving time slot by the access unit of the station. The actions produced in those ten instances are in terms of setting or resetting a request bit and advancing, reducing or resetting contents of one or more counters.

Title: Seismic recording
IPC: G01V1/26
Filed: 1982-05-31
Abstract: A method and apparatus for indicating the time-break on a seismic record wherein the time-break is marked in response to the rupture of an electric circuit by the explosive charge used to generate the seismic waves. The preferred rupturable electric circuit is connected to the same energy source as the electric detonator used to initiate the explosive charge and the preferred electric detonator is one connected to a high frequency A.C. firing energy source through a transformer, the rupturable electric circuit being the primary or secondary circuit of the transformer. The method is more accurate than the present method of marking the time-break at the initial application of current to the detonator.

Title: Method for avoiding alchohol losses in the utilization of recuperated heat from distillation columns for drinks with high alchohol content
Inventor: DJAKONOV PAVEL M
IPC: C12H6/02
Filed: 2001-03-05
Abstract: The invention relates to a method for the seizure of alcohol, possibly found in the alcohol-removed liquor (vinasse), discharged from the distillation columns for drinks with high alcohol content, as well as for the recuperation of the waste heat contained in it. The hot vinasse continuously runs through a vacuum vessel where the alcohol boils, and in the form of a secondary vapour goes back to the column. The vacuum in the vessel is formed by a steam ejector, using the pressure drop of the heating steam, which intakes the secondary vapours from the vacuum vessel and feeds the produced steam and vapour  mixture to the heating bubbler of the column. The vinasse from the vacuum vessel goes gravitationally, or by means of a pump to a surface heat-exchanger, where it renders its heat to the treated water, supplying the steam boiler. In this way its residual heat is recuperated. 1 claim, 1 figure
