IPC: H03K21/00
Filed: 1978-11-22
Granted: 1982-01-12
Abstract: ABSTRACT OF THE DISCLOSURE      A condition responsive time proportional control means which has a relatively fast time constant when operating in its proportional band has the time constant expanded by means of a digital counter.  The counter is repetitively switched by the condition responsive means and counts the switched operation.  During the period that the switched operation is occurring, the time constant is expanded by simultaneously counting pulses from a pulse generating means.

Abstract: Abstract of the Disclosure The mechanism cuts component lead portions projecting from a support such as a circuit board though the leads may be spaced apart at different distances, and then clinches them against the board.          Additionally, the mechanism is movable heightwise relative to the support for clearance purposes and adapted to be shifted both in X-Y directions and with selected radial orientation between preset angles.          The clinching is done in opposite directions and normal to a line interconnecting the points from which the leads protrude thereby stabilizing the position of a component body.

Abstract: ROLLOVER AND WIPE PROTECTIVE CIRCUIT   FOR AN ELECTRICAL SWITCHING ARRAY                         ABSTRACT      A control panel influenced by the touch of an opera-tor is disclosed in which the density of individually selectable inputs may be increased by the provision of protective measures for preventing inadvertent or acci-dental actuation of inputs which are located closely adjacent to an input that is intended to be actuated. A protective circuit for an electrical switching array is disclosed effective to prevent selection from being made unless the switching is effected by the operator in a prescribed fashion to prevent unintended selection in the event that the operator's finger should roll onto an adjacent switch during the selection process.  The pro-tective circuit also prevents further selection once a selection has been effected until the operator's finger is completely withdrawn from the switching array in order to provide protection against a series of consecutive selections in the event that the operator were to wipe across the switching array.

Title: Cleaning process control method for  textile barrier filter material
Inventor: APELGREN ROLAND
IPC: B01D46/46
Filed: 1980-02-11
Granted: 1982-06-15
Abstract: ABSTRACT     A method of controlling the cleaning process for the cleaning of textile barrier filters, for example bag filters, subse-quent to dust precipitation on the filter material.  The cleaning is carried out with a cleaning system comprising means for distributing compressed air pulses to the filter bags.  The gas flow often shows great variations in flow, temperature and dust content, thereby giving rise to problems in the control of the cleaning process in such a manner, that neither over-cleaning nor under-cleaning occurs.  For the control, the filter load vf is measured which is the ratio of the gas flow (m3/s) and the filter area (m2), as well as the pressure drop Pf over the filter material.  At applications with great temperature variations of the gas, also the absolute temperature T is measured.  The measuring results are processed in an electronic unit for calculating the filter resistance S, which is the ration Pf/vf, possibly standardized to a reference temperature To by multiplication with the ratio  (To/T).alpha., where .alpha. is a constant with the value 0.76 at gas temperatures below 200°C.  Through the filter resistance S the cleaning process is controlled by acting upon the cleaning interval, the time interval between the cleaning pulses, the cleaning pressure of the cleaning pulse or the duration thereof.

Abstract: HYDROGENATED BLOCK COPOLYMERS OF BUTADIENE CONTAINING  A BLOCK OF 1,4 AND A BLOCK OF 1,2-MICROSTRUCTURE                ABSTRACT OF THE DISCLOSURE     The composition described herein is a hydrogenated polymer derived from a butadiene diblock copolymer having 85-100%, preferably 95-100% 1,2-structure in one block and the other block comprising essentially 1,4-butadiene.  The 1,2-block comprises at least 10%, preferably at least 25%, of the total weight of the diblock copolymer.  The hydrogenated product is an elastomeric material which is oxidation-resistant and stable against ozone.  Moreover, since the original polymer may be made by a method which permits control of the molecular weight, the molecular weight of the ultimate hydrogenated product is also controllable.  The control of molecular weight and microstructure give highly desirable properties in the ultimate elastomeric product, and also control of tacticity and crystallinity.
