Abstract: With a method and a device for producing a helper signal for determining the point in time for a defibrillation or a cardiac massage given a cardiac arrest, the value (W) of the blood flow (B) into the head of the patient affected by the heart malfunctioning is used in order on the one hand to determine the necessity for activating the reanimation impulse (current shock/cardiac massage) and in order on the other hand to indicate whether the blood supply of the brain is sufficient. In order to be able to quickly lay the arrangement for measuring the blood flow onto the carotid artery, the measuring arrangement (10) consists of a multidude of individual flow measuring units (11, 11′) arranged next to one another.

Abstract: Adverse inflammatory reactions can be treated by administrating to an organism a composition having diglucosylamine as the active ingredient. The preferred compound is di-Beta-D-glucopyranosylamine. A simple method for making diglucosylamine in high purity is obtained by reacting glucose, a nitrogen containing base, and either methanol or ethanol to form the diglucosylamine and then recovering the diglucosylamine preferably with the use of charcoal. The preferred diglucosylamine, di-Beta-D-glucopyranosylamine, has extraordinary anti-inflammatory activity. It can be formulated with a pharmaceutically acceptable carrier to make pharmaceutical compositions which are effective in treating inflammations. This pharmaceutical composition can also be used to treat adverse inflammatory reactions that are the result of the disruptions of a dynamic network of cellular mechanisms in organisms.

Abstract: ADSS cable is laid out a length of cable along an aerial route defined by a series of poles, and loops of surplus cable are formed at occasional poles. The cable is raised to a predetermined installation height at each pole, where two dead-ends secure the ends of the loop so that the loop is substantially free of tension. The center of the loop is raised and secured to the pole, thus forming two bights in the loop. A bend radius protector is installed in each of the bights to protect the cable from bending damage. Each bend radius protector is suspended from a cable protecting device placed over the taut cable, so that the cable is not damaged.

Abstract: Methods and apparatus for authentication of postage indicia are disclosed. A secret key is read from store and modified in dependence upon postage data to be printed in a postage indicium. The modified key is then utilized to generate an authentication code dependent upon the postage data to be printed. Authentication of the indicium is effected by reading the authentication code and postage data from the printed indicium and repeating the process of generating an authentication code. The generated authentication code is compared with the authentication code read from the indicium. A control code based on a value in an accounting register may be included in the indicium. The value may be a value of postage dispensed in a determined expired period.

Abstract: Semiconductor wafers are glued onto a carrier foil which is stretched across a frame. Instead of restretching the carrier foil directly at a processing machine, the foil is restretched on an adapter frame which can be stored and then later manipulated in the processing machine. The adapter frame includes a clamping ring, a base ring, and a threaded ring which secures the carrier foil.

Abstract: This invention provides a system that utilizes the magnetic properties of specific materials to provide an authentication and/or authorization function. The system consists of two parts. The first is a marker that contains a magnetic material with spectral magnetic properties and is attached to the item that is to be authenticated or is to be part of a subsequent information transfer process requiring authorization. The second is a reader. The reader contains a transmitter that generates the electromagnetic search field and energizes the magnetic material and a receiver that analyzes the signal produced by the resulting interaction with the magnetic material and gives a go/no go decision based upon a match with stored information. The reader employs a feedback control system to stabilize the measurement environment, thereby producing accurate, high quality results.
