Patent EP-0067936-A2 (EP)
Inventor: ARNOLD ROBERT WALKER
IPC: H01H47/32
Filed: 1982-04-15
Abstract: A constant energy drive circuit for an inductive load, e.g. an electromagnetic print hammer has a chopping circuit including a comparator (19) which cycles a switch means (10. 14) connecting the energizing coil (11) of the print hammer to an unregulated power supply. Changes in the drive voltage (V1) of the unregulated source are compensated for by altering the switching rate of the switch means by adjusting the amplitude of a reference signal (V<sub>R</sub>) applied to the comparator. The reference signal adjustment is inverse to changes in the drive voltage.

Abstract: The brick consists of one or more sub-blocks (1, 2, 3). Each sub-block is divided into air chambers (4-13) of contained width but extensive in length. The walls (14, 14'; 15, 15'; 16, 16') which divide each sub-block into chambers are shaped as alternatively concave and convex arcs of a circle. The chambers are connected by septa (17, 18, 19) of minimum length. The sub-blocks are connected by septa (20, 21,22, 23) also of minimum length and never concident with the periphery of the brick nor placed in correspondence with the inner cores of the successive sub-block, on a line with them. 
     Thermal bridges between the inside and outside of a wall are thus almost completely eliminated, with a brick light in weight, very strong and low in cost (Figure 1).

Abstract: A telescopic sight is disclosed which may be used as a riflescope for viewing objects at different viewing distances. The telescopic sight is provided with a focus adjustment means for longitudinal movement of the erector lens unit relative to an objective lens, an eyepiece lens and a reticle within the housing of such telescopic sight while maintaining a substantially constant magnification over the range of viewing distances. Such focus adjustment is accomplished in a simple manner with a rotatable knob coupled to the erector lens unit by a pin which is offset from the axis of rotation of such knob for orbital rotation, such axis of rotation extending laterally substantially perpendicular to the longitudinal movement of the erector lens unit. The objective lens and the eyepiece lens of the telescopic sight are fixed during focus adjustment of the erector lens unit. as is the reticle scale which is positioned between the eyepiece and the erector lens unit. As a result, telescopic sight is provided with substantially constant magnification throughout the range of focus adjustment so that the scope power changes less than 10.0% because the magnification of the erector unit changes less than 1.0% when focusing for objects at different viewing distances between infinity and 100 meters.

Abstract: A sample stream is conditioned by the addition of reagents and the ion concentration is measured by means of a measuring system which can be connected to an arrangement for releasing an appropriate calibrating substance. The calibrating substance used is a soluble glass for the defined release of a known quantity of the ions to be measured, and the reference concentration is established directly in the sample stream. There is therefore no need for a calibrating solution or a metering pump for the latter, and disturbances due to the undesired transfer of impurities and reactive ions are avoided. The method is particularly suitable for the analysis of Na+, the soluble glass being a sodium polyphosphate glass.
