Title: Window glass breakage ultrasonic SENSOR - uses carrier and pulse signal to transmitter to provide protection against external disturbances
Inventor: SCHMEISSER FRITZ DIPL ING
IPC: G08B13/16
Filed: 1975-09-19
Abstract: An ultrasonic sensing system for detecting breakages in large glass windows is designed to reduce the sensitivity of the system to unwanted disturbances e.g. wave reflections causes by external effects. The system uses an oscillator generating a carrier frequency of 100-200 kHz and a low frequency pulse generator. The two signals are combined before transmitting over an ultrasonic sender located in one corner of the window. A reciever transmits to a demodulating amplifier. The output reciever gating circuit only transmits an output when the signal from the low frequency generator is present after processing over a shaping stage. The alarm output stage is in the stand-by condition so long as the pulses are regularly generated.

Title: Pantograph for field use - has main pin coupled by three ropes under tension to arm carrying pencil
Inventor: EICHSTAEDT PETER
IPC: B43L13/10
Filed: 1976-05-05
Abstract: The pantograph is partic. for field use, recording details of earthworks, strata, excavated findings etc. having a main pin followed by a drawing pencil working to a different scale moving about a stationary axis. The main pin performs its radial movement by travelling along a straight guide at right angles to the axis and slewing on it. From the main pin a central rope under tension runs back to the axis (7), and this rope transforms the alteration in length of the radius vector between pin and axis into a radial movement of an arm (15), also slewing on the axis and carrying the pencil (18). Two further ropes (23, 24) under tension diverge from the main pin, the central rope lying between them, and transmit angular movements of the pin to the arm.

Abstract: In a new process for the prepn. of azomethine derivs. of formula R1SO2-N=CH-CCl3 (I) (where R1 is F, Cl or an opt. substd. organic residue), chloral is reacted with a sulphonyl isocyanate of the formula R1-SO2-N=C=O (II) in the presence of >=1 tert. amine and/or at least one quat. ammonium base at ca -20 to +120 degrees C. Cpds. of formula (I) in which R1 is F or Cl are new and claimed. Partic. useful is intermediates for amino acids are (I; R1 = F) and (I; R1 = Cl); reaction with isobutylene, catalytic hydrogenation and boiling with dil. HCl gives leucine hydrochloride. The new process enables previously unobtainable cpds. to be produced, and considerably facilitates the prodn. of known cpds. (I). In an example, a mixt. of fluorosulphonyl isocyanate (687 g) and triethylamine (20.6 g) is treated dropwise over 3 hrs. at 30 degrees with chloral (736 g). Distn. of the reaction mixt. gives (I; R1 = F) (920 g).
