Title: Saw blade
Inventor: ERHARDT HERBERT
IPC: B27B33/02
Filed: 1984-01-12
Granted: 1987-08-13
Abstract: PCT No. PCT/CH84/00006 Sec. 371 Date Sep. 11, 1984 Sec. 102(e) Date Sep. 11, 1984 PCT Filed Jan. 12, 1984 PCT Pub. No. WO84/02676 PCT Pub. Date Jul. 19, 1984.The teeth of the saw blade (1) intended for preparing wood comprise a cutting edge (2) beginning at the tip (6) and forming an angle of intersection ( delta ) of 40 DEG -55 DEG . Adjoining the cutting edge (2) at the tooth face there is a cut-back, circular curved section (3). This curved section (3) continues at the bottom into a rounded base (4) between adjacent teeth and then continues into the edge (5) bordering the gap between the teeth, and on into the back of the next tooth. A considerably increased cutting performance is achieved with a saw blade of this kind, since a paring action is effected, and the shavings can roll away easily. Saw blades equipped with this kind of teeth can be made both as circular saw blades and also as bandsaw blades which are moved in a straight line.

Title: Process and arrangement for measuring an electric signal arising in a circuit
Inventor: FAZEKAS PETER DIPL ING
IPC: G01R31/28
Filed: 1984-09-06
Granted: 1988-09-08
Abstract: A method for measuring electrical signals according to a sampling principle with the assistance of an electron probe, whereby the signal is respectively repeatedly sampled in succession at different phase points, enables a fast registration of an electrical signal at a circuit node of an integrated circuit and simultaneously permits registration when at least one noise signal appears between two clock edges of a basic pulse rate of the integrated circuit. Between two successive phase points at which the signal is repeatedly sampled in succession for potential measurement, only a check is executed at phase points by sampling as to whether a noise signal exists in this intermediate region.

Abstract: A communication system comprises a main station 1 which defines a time frame containing a variable number of time slots. Each of a plurality of substations 2, 3, 4 etc., includes selection means for selecting a time slot for transmission of information to the main station. Each substation has an identity number and it divides this identity number by the number of time slots currently set by the main station. The remainder left after this division process is used to select the time slot in which the substation will transmit its information to the main station. If two substations transmit in the same time slot the mutilated time slot is recognised by the main station at 15 and 16 and the number of time slots defined at 17 for the next frame is changed so as to prevent repetition of such mutilation.

Abstract: The adder allows a bit parallel addition of binary values in two complements using a set of adder stages (ADi) providing intermediate sum and transfer words. The saturation of the adder is effected by a decoder in response to the two highest value bits of the intermediate sum and transfer words providing the overflow signal. This controls logic circuits for the recursive circuits eliminating the intermediate sum and transfer words and providing saturation sum and transfer words. The saturation sum and transfer words are selected to ensure that a sum value not exceeding the max. permissible sum is obtained.

Abstract: A substantially purified preparation containing one or more soluble Iron-Releasing Monokines and a method of preparing and using same are disclosed. The monokine is heat labile and is retained by ultrafiltration on a YM-10 membrane. Molecular exclusion chromatography of macrophage conditioned supernatant containing the monokine yields fractions in the 30,000 to 65,000 relative molecular weight range with iron-releasing activity. Kinetic studies show that the monokine is rapidly released from activated macrophages after triggering with bacterial endotoxin, reaching plateau levels within 2-4 hours. The response of cells to the monokine depends on both the dose of the monokine administered and the duration of its exposure. The Iron-Releasing Monokine is distinct from other factors secreted by activated macrophages, such as a cytolytic factor and Respiratory Inhibition Factor which causes reversible lesions in the electron transport chain.
