Abstract: Sphygmometer has means to apply a selectively variable pressure in the neighbourhood of a blood vessel. A device measures a fluctuating magnitude which is proportional to the sum of a time-dependent fluctuating component reproducing the pulsating pressure inside the bloodvessel and the selectively variable pressure applied externally to the blood vessel. The fluctuating magnitude is transformed into an electronic signal reproducing a time derivative for at least the fluctuating component of this magnitude. Another device analyses variations in the electronic signal derivative caused by changes in the applied pressure whilst a third device produces an output signal from the analyser indicating the physical condition of the subject under investigation.

Patent NL-7705704-A (NL)
IPC: B31B50/64
Filed: 1977-05-24
Abstract: Apparatus for forming a seal between layers of a carton of thermoplastic coated paperboard material and the like wherein the thermoplastic material in the area to be sealed serves as the sealant and is activated to flow by frictional heat generated by a vibration welding horn and is then allowed to cool and set under pressure to form the seal between the layers. The carton first moves to an activating station wherein the layers to be sealed are engaged on opposite surfaces by a vibrating horn and a back-up means for a time sufficient to activate the thermoplastic material to flow. The carton is then carried to one or more clamping and sealing stations at a different location from the activating station with the thermoplastic material in the activated state. The layers to be sealed with the activated thermoplastic is then engaged on opposite surfaces by a pressure pad and a back-up means for a predetermined period of time to permit the activated thermoplastic to cool and set and form a seal.

Title: Monitor system checking change of state in objects - has central control in separate building supplying fault indicators with constant current
IPC: G08B25/04
Filed: 1977-06-07
Abstract: The monitoring system is intended to observe any changes in the condition of a number of objects. Each object operates in conjunction with a fault indicator which is linked to a central monitoring unit via a two-wire cable. The latter is common to all the objects being monitored. The system can be applied as an alarm against burglary or as a control of the liquid level in a container. The central monitoring unit (1) can be installed in a separate building and linked to the fault indicators via the common cable. Each fault indicator has a circuit (6) which draws a constant current from the central control. The fault indicator circuits incorporate sensing elements (38) which interrupt the flow of current to all the other fault indicators when there is a change of state in one of the indicators. The total current supplied is measured in the central control.

Title: Quantitative determn. of methyl bromide in gas, e.g. air - by passing as through two oxidising zones to form all bromide into bromine, and trapping on cuprous bromide indicator in third zone
IPC: G01N31/22
Filed: 1978-01-31
Abstract: Quantitative determn. of CH3Br in a gaseous mixt. comprises passing the mixt. through a carrier having 3 successive zones. In the first zone the CH3Br is oxidised to Br2 and HBr; in the second zone the HBr is oxidised to Br2; and in the third zone all of the Br2 is entrapped by CuBr indicator. The change of the indicator colour is used as a measure of the CH3Br content in the gas. In the first zone oxidn. is effected using (a) sulphuric anhydrie or oleum in the presence of (b) iodine pentoxide deposited on (c) an active silica gel carrier, these components being in the following percentages by wt. resp. 10.44-28.73:0.04-2.3:89.52-68.97. In the second zone oxidn. is effected using (a) KmnO4 in the presence of (b) iodine pentoxide deposited on (c) an active silica gel carrier, these components being in the following percentages by wt. resp. 0.02-3.09:0.05-4.61:99.93-92.3. In the third zone the indicator comprises (a) CuBr deposited on (b) act ie silica gel or glass powder, these components being in the following percentages by wt. resp. 0.09-2.92:99.91-97.08. The process is esp. used to control the CH3Br content of air in order to prevent poisoning during operations with it; as well as for sanitary measurements of the gas content in the ambient atmosphere at the sites of fumigation of vegetable and other prods. All the stages in the process are performed in a single indicator tube which allows determn. to be carried out under field conditions, e.g. in ship-bilges, stores houses and other premises. Determn. of CH3Br content in the air takes only 15-20 sec., and no special training is required.

Patent NL-8803017-A (NL)
IPC: B41F15/26
Filed: 1988-12-08
Abstract: A rectangular product (20), such as a crate or tray is printed by simultaneously using two screens (5, 6) of a screen printing machine, which are located next to each other and in planes extending at a right angle to each other. After printing of two subsequent sides of the product, the product (20) is removed from the screens (5, 6) and rotated through 180 DEG whereupon the product is once again pushed against the screens for printing the two other subsequent sides of the product. A screen printing machine for executing this process comprises a frame (13), a squeegee (10) for feeding ink from a tank (7) to the top side of two vertical screens (5, 6) extending at right angles and next to each other, a product clamp (19) and a platform (8) for feeding, for discharging and for maintaining the product during printing. The platform (8) carries a guide (4) at its bottom side. In order to turn the product (20) alternately clockwise and anticlockwise into the two printing positions for printing the four sides of the product the guide element (4) is able to engage a first rotary guide track (9a) which turns the products during its movement to the screens (5, 6) through 90 DEG . After printing of two subsequent sides the guide (4) moves back over guide track (9a) and returns to a position allowing engagement with a second guide track (9b) turning the product once again through 90 DEG  but in an opposite direction. After said second printing the printed product (20a) is discharged through feeding-discharge station (3). The ink tank (7) of the printing machine is positioned at the bottom of the machine and a pump (18) pumps ink to the top side of the screen. A drip tray (12) collects excess ink also at the bottom side of the screens.

Title: Preheating of raw materials for glass-making
IPC: C03B3/02
Filed: 1992-01-31
Abstract: Raw materials for mfg. glass are preheated in a fluidised bed with exhaust gases from the melting furnace. Fine dust particles of 0.05-10 microns are reclaimed from the gases by electrostatic pptn., using pref. at least one electrode pair placed either side of the bed. Electrodes form a corona and are powered by a high tension supply; at least one electrode may be in the form of a screen or plate. Addn. of material, e.g. chalk, to the gases removes detrimental acidifying cpds. from the raw materials. Exhaust gases from the furnace are pref. passed through a regenerator to preheat incoming air and into the bottom of the reactor at about 470 deg.C. Sieve plate holds the raw materials which may include crushed glass and passage of the gases fluidises the mixt. Gases exit at about 370 deg.C having heated the bed to about 350 deg.C and enter a cyclone and further dust particles are recirculated to the reactor. Preheated material is passed to the melting furnace via. Corona (10) and pptn. electrodes are placed either side of the bed and powered by a supply. Movement of the materials keeps the upper electrode clean when this is placed in or just above the bed. Material, e.g. chalk, may be added to the exhaust gases by a dosing arrangement prior to entering the reactor.

Title: Sheet material carrying an unibtrusive image and method for its production
IPC: B41M3/10
Filed: 1980-10-13
Abstract: An unobtrusive image is applied to paper or other sheet material by means of a charged droplet printer, for example an ink jet printer. The unobtrusive image applied may perform the function usually associated with a watermark in paper, but in contrast to a watermark, may be applied to papers during their production on high speed wide deckle machines or to coated papers. The method is particularly suitable for unobtrusively imaging pressure sensitive copying material.
