Title: Determining position of any part of skull with respect to nasion - involves horizontal beam structure with sliding elements mounted on nasion
Inventor: HOERSCHELMANN STEPHAN
IPC: A61B5/103
Filed: 1992-02-15
Abstract: The position of any part of the skull with reference to the nasion (4) is determined in three mutually perpendicular planes (5,6,7). The nasion (4) forms the origin (2) of a system of coordinates. A horizontal beam has a central fixing attachment which enables it to be attached to the nasion (4) and extends horizontally in opposite directions in a line lying in the plane (6). This beam has longitudinal slots which form guides for slides which support sight tubes. USE/ADVANTAGE - The system enables the growth of the skull to be monitored. It also can be used to determine the exact position of the joint of the lower jaw with the upper jaw when making dentures for a patient.

Inventor: OSTI ROBERTO
IPC: B65B51/16
Filed: 1992-07-29
Abstract: Commodities 4, eg cigarette packets, emerge from a wrapping or overwrapping machine enveloped in respective wrappers to be sealed, and are directed by an infeed mechanism 2, driven by drive means M1, into one end of a channel 12 that forms the basis of a sealing device 1 which comprises a feed means 24, by which the commodities 4 are directed along the channel 12, and a drive system (M, Figure 2), independent of drive means M1, by which the feed means 24 is moved in such a manner as to determine the duration of the passage of the single commodity along the sealing channel 12 according to the physical properties of the wrapping material and independently of the frequency at which the commodities 4 are received from the wrapping machine. Channel 12 preferably defines an arc of a circle and may be defined radially inwardly and outwardly by guide belts 13, and laterally by sealing, rotating heated discs (10, Figure 2), the axis of rotation of the discs being angled so that the minimum clearance between the raised profiles (11, Figure 2) of the discs occurs midway along the channel 12. A push rod 28 may move each commodity from the wrapping machine to the channel, a rockable forked element with prongs 26 acting in association with a plate 15 and a pair of restraining plates (27, Figure 2) to transfer the commodity between a position aligned with infeed mechanism 2 and a position at the start of the channel 12. A rectilinear branch 23, defined by further conveyor belts, may form a runout channel. <IMAGE>

Title: Shut=off assembly for electronically-controlled drive of working machine - monitoring load current by sensor coupled to differentiator, threshold switch and main switch for control electronics
Inventor: KUEHNEL ANDREAS DR
IPC: G05D13/04
Filed: 1992-09-23
Abstract: A current sensor (3) is installed in the current path between the power source (1) and the control electronics (2) for the drive (7). The sensor generates a voltage signal proportional to the current and this is passed to a differentiating circuit (4) whose output signal is proportional to the acceleration of the drive. Along with a reference signal, it is passed to a threshold switch (5) and the main switch (6). The output of the latter turns off the control electronics when necessary. An alternative circuit has a low-pass circuit between the current sensor and the differentiating circuit with a second threshold switch and a delay circuit as extra inputs to the main switch. USE/ADVANTAGE - Prevents damage, e.g. to biological tissue, during sudden load change by monitoring load current esp. in medical drill for surgical treatment of bone fractures.

Title: Biodegradable, thermoplastically mouldable materials made from starch esters
Inventor: RAPTHEL INNO DR
IPC: C08L3/06
Filed: 1993-08-04
Abstract: The relatively brittle starch esters are to be modified in such a way that they can be moulded at acceptable economic cost using known thermoplastic processing methods without adversely affecting the properties of the end products and the biodegradability. This is achieved by modifications comprising blends of starch esters having degrees of substitution of < 3 and polyalkylene glycols having molecular weights of from 200 to 2000. Both amylose-rich special starches and conventional natural starches can be employed for the thermoplastically processable blends. The products allow great variation latitude in the processing properties and exhibit no significant drop in quality even after an extended storage time.
