IPC: G01N21/03
Filed: 1974-08-05
Abstract: A cuvette having a tubular body, an upper head portion and a lower substantially conically shaped portion having a central port defining an entrance. An examining chamber is defined within said cuvette body. The interior walls of said body are characterized by the absence of sharp angular junctions so that there are smooth transitions between adjacent planes within the chamber. A ball preferably of glass is seated at the entrance upon at least a pair of inwardly directed upset portions so that the ball is prevented from tightly seating in the cuvette entrance. The combination of the ball and upset portions provides an impedance to outflowing liquids from the chamber through the lower port. The head portion of the cuvette comprises an end cap or plug sealedly engaged removably within the upper end of the body and having a through passage terminating in a port directed to the body interior radially of the axis of said body. A probe secured to the lower end of the cuvette body at the entrance completes the cuvette assembly.

Abstract: 1473197 Power converters FERRANTI Ltd 21 Oct 1975 [23 Oct 1974] 46896/74 Heading H2F A power converting system comprises a switching transistor 15, a transformer 12 for storing energy from an input power supply when the transistor is conducting and for transferring energy to a load 28 when the transistor is non-conducting, and comparators 21, 32 for controlling the transistor in accordance with the level of current flow to and from the transformer. A D.C. source is connected to terminals 10, 11 and a reference voltage is supplied to an input 22 of the comparator 21. When the current flowing through the transformer primary winding 13 causes the voltage across a resistor 18 to exceed the reference voltage, the comparator 21 supplies an output via a NOR gate 24 to block the transistor 15. The energy stored in the transformer is then discharged through the load until either a load voltage comparator 36 detects that the load voltage has fallen below a reference voltage or the load current comparator 32 detects that the load current has fallen below a reference value whereupon the output of the comparator 36 or 32 switches on the transistor 15 via the NOR gate 24. In a modification, Fig. 3 (not shown), the output of the transformer is isolated from the input and the outputs of the comparators 32, 36 are supplied to the NOR gate via an opto-electric isolator. In Fig. 4 (not shown), the D.C. output of the transformer is converted to A.C. by a thyristor or transistor bridge circuit.

Abstract: METHOD OF PRODUCING A ROTARY THERMODYNAMIC EXCHANGER This invention relates to a method for producing a rotor or similar body for moisture and/or heat exchangers containing a transferrer mass composed of alternately plane and corrugated layers with the corrugations extending in axial direction so as to form a plurality of axial narrow channels extending from end to ends In order to increase the moisture and/or heat transferring capacity of the exchanger rotor, the continuity of said narrow axial channels is partially interrupted at predetermined places by the corrugaged layer or layers being formed with a plurality of stripshaped portions displaced relatively to one another in the peripheral direction of the rotor for a distance preferably amounting to between one-half and one-third of the individual corrugations.  The increase of the resistance to flow in the longitudinal direction of the channels created in this way at the transitions from one strip-shaped portion to the displaced adjacent portion is kept at so low a value that said resistance nowhere falls below the resistance to flow in the direction across said channels.

Abstract: An arrangement for the processing of a moving material web, in particular for the creasing or punching of an extruded material web made of plastics. In the manufacture of such material webs a number of operational steps take place directly in conjunction with the manufacture of the web itself, and the fact that for reasons of quality as well as of manufacturing technique the extrusion process cannot be interrupted makes it necessary to attend to any changes in the crease pattern etc. during operation. The arrangement in accordance with the invention makes this possible, in that the material web can be brought into contact optionally with different pairs of processing rollers with the help of a pair of counter-rollers supported in a swivelling cradle, any pair of unused rollers being freely exchangeable against a pair of rollers with a different creasing pattern. The arrangement permits the processing of both sides of the web and the rapid exchange of different processing patterns during continuing production, which is particularly advantageous in the processing of material webs for the manufacture of packing containers.
