Abstract: Novel-Z-2-Acylamino-3-monosubstituted propenic acids and their esters and salts of the formula
     wherein R, is, by preference, hydrogen, lower alkyl or a pharmaceutically acceptable cation, R 2  is, by preference, methyl substituted cyclopropyl, (cycloalkyl)alkyl, straight alkyl with more than 4 C-atoms or ramified alkyl and R 3  is, by preference, optionally substituted alkyl, are prepared by reacting compounds of the formula
     with compounds of the formula
     or by acylation of esters of the formula
     with an acid chloride
     and treating the obtained acylated esters to the formula
     with t-butylhypochlorite and sodium methoxide, followed by treatment of the resultant intermediate with anhydrous hydrochloric acid. The novel compounds selectively inhibit the metabolism of dipeptidase (E.C.3.4.13.11) and therefore are useful in combination with antibacterial products, by preference with the thienamycin class of compounds.

Abstract: A dental handpiece is disclosed with a transducer assembly for holding a work tool which is caused to vibrate at substantially a resonant frequency by a variable frequency oscillator (20). The oscillator (20) sweeps through a spectrum of frequencies under control of oscillator control means (24). A maximum in the current flow through the transducer assembly occurs at a resonant frequency and is detected by maximum detecting means (22) which then generates a latch signal to stop the oscillator at substantially that resonant frequency. Hence the oscillator is correlated to the resonant frequency of the assembly, and subsequent changes in the loading conditions on the assembly do not affect the oscillator frequency.

Abstract: A video record system includes a record disk 12 and a read/write head 19. A signal to be recorded is received on line 15 and processed by a converter 26 before being passed to the read/write head 19. A signal read from the disk 12 by the read/write head 19 is passed through a converter 30 and a digital signal processor 32 to a television 14. 
     In this video record system the length of a mark along a record track 20 on the disk 12 represents a four bit binary storage code block and the player/recorder system operates in eight-bit system code blocks. Thus, two marks on the disk represent a single system code block. The bits of the system code block are assigned to bit positions of the storage code blocks in such a way that there is a reduction in the effect in the associated system of errors in initially writing or subsequently reading a mark. The increments of mark length are also made non-constant to reduce the effect in the associated system of errors in mark length.

Diese Öffnung werden dann mit Isolationsmaterial, beispielsweise Siliciumdioxid gefüllt (64). Eine leitfähige Schicht (66) aus N<+>-dotiertem polykristallinem Silicium wird nun auf der bloßen Oberfläche des Halbleiterkörpers aufgebracht. Danach werden wieder Öffnungen in die polykristalline Siliciumschicht direkt über den gefüllten Öffnungen hergestellt. Ferner wird eine Siliciumdioxidschicht (68) auf der polykristallinen Siliciumschicht aufgebracht. Jeder zweite mit Isolationsmaterial aufgefüllte Bereich (64) wird nun mittels reaktiven Ionenätzens bis in das P-leitende Substrat geöffnet, so daß in den monokristallinen Silicumbereichen jeweils zwei Speicherzelien und in der polykristallinen Siliciumschicht eine Bitleitung (66) für jede Speicherzellenspalte entstehen. Es wird dann eine Silciumdioxid-Isolationsschicht (72) für die Bildung der Gates auf die monokristalline Oberfläche der U-förmigen Öffnungen mittels thermischer Oxidation in geeigneter Atmosphäre aufgebracht. Leitend dotiertes polykristalline Silicium (75) wird in die Öffnungen über die Gate-Isolation aufgebracht, bis auch die gesamte Oberfläche des Halbleiterkörpers damit bedeckt ist. Danach wird die Oberfläche mit einem Muster geätzt, das die Wortleitungen einer Speichermatrix ergibt.

Abstract: Die Regelschaltung weist eine Regelstrecke, einen Regler (3) mit I-Glied (7) und einen Stellmotor (15) mit limitierter Stellgeschwindigkeit und Rückführung (22) auf. Ueber die Rückführung wirkt der Hub des Stellmotors (15) auf ein in den Regelkreis zwischen dem Ausgang des Reglers (3) und dem Eingang des Stellmotors eingeschaltetes Vergleichsorgan (11) ein. Der Ausgang des Vergleichsorgans (11) ist zusätzlich auf Abschwächungsmittel (34, 36) geschaltet, die im Eingangspfad des I-Gliedes (7) wirken. Die Abschwächungsmittel umfassen einen Funktionsgeber (34) und ein Multiplikationsorgan (36). Der Funktionsgeber gibt bei hohem Absolutwert seiner Eingangsgrösse ein kleineres Ausgangssignal ab als bei tiefem Absolutwert. Das Ausgangssignal des Funktionsgebers (34) wirkt über das Multiplikationsorgan (36) auf den Eingangspfad des I-Gliedes (7). Hierdurch lassen sich Regelschwingungen der Regelschaltung vermeiden, insbesondere bei periodischem Auftreten brüsker Störungen.

Abstract: A protection valve for fluid operatet systems, having two or more valve elements each of which opens against a bias to admit fluid under pressure to an associated fluid operated system and comprising a plunger (40) biased toward a position wherein it closes off an outlet port for connection to the associated system and carrying a non-return valve (44) which is movable to the plunger (40) such that communication between a bleed-hole (52) through the non-return valve (44) and the outlet port associated with the valve element is cut off below the closing pressure of the valve element. Because the bleed by-pass (52) is only active between valve opening and closing pressures, all sound systems can be protected against failure in any other system below valve closing pressure.

Abstract: A surgical fluid evacuator comprises a flexible, compressible reservoir which draws a substantially constant vacuum to permit uniform removal of fluid from a surgical incision through a wound drain catheter. The reservoir comprises a pair of congruent, articulated plates (10a, 10b) having the area between them sealed from the atmosphere by a flexible membrane 40. A spring (14) between the plates (10a, 10b) biases them apart to create a vacuum in the reservoir. As the reservoir, and spring, expands to draw fluid the articulated plates hinge to vary the shape of the reservoir to at least partially offset the decreasing force of the spring on the plates.
