Title: Process for the preparation of ultrastretchable polymer material,ultrastretchable material,as well as a process for the manufacture of objects
Inventor: WAAGEN GEERT NICOLAAS
IPC: B29C67/24
Filed: 1988-05-20
Abstract: An ultrastretchable polymer material is prepared starting from polyolefine particles with a low entanglement density and a weight average molecular weight (MW) higher than 400,000, the particles being densified to a coherent material together with a process auxiliary material at an elevated temperature, but below the melting point of the pure polyolefine. From this ultrastretchable material, objects with a high tensile strength and a high modulus can be produced by stretching it, for instance, at a temperature which is at most 70 DEG C below the temperature at which the polyolefine melts under the prevailing conditions, if desired after removal of the process auxiliary agent present in it.

Filed: 2003-12-12
Granted: 2006-05-24
Abstract: A method and apparatus for measuring an apparent depth of a section of an animal body are disclosed. Light is focused concurrently to an extended focal region comprising a plurality or continuum of measurement locations. Light reflected by a refractive index interface coincident with one of the plurality of measurement locations is detected. Detected light signals are generated from light reflected from first and second interfaces respectively defining the section under investigation, so that the apparent positions of the interfaces may be derived. A confocal arrangement and an axicon element may be employed. Preferably, the section is the aqueous humor of an eye. From changes in its refractive index corresponding changes in glucose concentration in the aqueous humor and, in turn, in the bloodstream of a patient may be derived, offering a non-invasive monitoring means for diabetic patients. Other compounds and structures of the body may alternatively be investigated.

Title: Apparatus for emptying containers
Inventor: RECK HERBERT
IPC: B65F3/04
Filed: 1992-08-28
Abstract: In order to make it possible to empty in particular, large containers with a crew of just one person, an emptying device with a tilting/lifting device 1 and a control unit 4 is described to which a trigger switch 2 is connected which is actuated by the container to be emptied as it approaches the lifting/tilting device and which triggers the raising phase of the lifting/tilting process automatically. When a preset raised level of the lifting/tilting device is reached the control unit interrupts the raising phase. In addition, a first manual actuator 8 to trigger the automatic emptying process, which actuator has an effect upon the control unit 4 only after the interruption of the lifting process, is connected to the control unit. The control unit 4 contains a programmable device 5 into which the preset raised level can be inputted. The programmable device 5 also assumes the function of monitoring the preset time spans, such as the time span between the actuation of the trigger switch 2 and the actuation of the acknowledgement signal switch 3. After the container is emptied, putting the container back down completely is accomplished by means of a second manual actuator 9.

Title: Floating oil slick collection system - using upright belt conveyors with steel strips mounted between catamaran pontoons
IPC: E03B/

Granted: 1979-04-10
Abstract: A boat, to collect oil slicks floating on the water surface, consists of a hull, such as a catamaran, which carries in the centre three endless vertical belt conveyers side by side. These can be lowered just below the water level and pick up the oil because of their greater adhesion than water, and take it to the top pulley where scrapers and chutes remove it to containers. Such a boat need not be turned round because the belt conveyor can be made reversible. When steel strips are used as belts, the oils collection efficiency can be as high as 100%.
Patent IT-1165438-B (IT)
Inventor: YIN HUO-BING
IPC: H04J3/04
Filed: 1979-12-18
Granted: 1987-04-22
Abstract: An adaptive delta modulation system is disclosed which features an improved digital compandor which may be used with a digital integrating network. The compandor executes a companding algorithm having a nonlinear characteristic to provide a rapid increase in step size to follow the fast rising start or fast decaying end of talkspurts in input signals so as to minimize any slope overload distortions and to provide a small increase or decrease in step size during the smooth portion of the talkspurts in input signals to reduce any granular noise effect. The step size generated by the compandor is directly related to the input signal level, providing a maximum companding range in which good signal-to-noise characteristics are preserved for the soft or low voiced speaker as well as for the loud voiced speaker and providing a fast transient response most suitable for telephone applications. The step size logic of the compandor has a built-in minimum step size circuit which insures that a well behaved idle pattern of alternating ones and zeros will appear at the digital output when the input signal is zero, and which provides a mechanism to rapidly build up the step size when an input signal appears. The step sizes can be integrated with an integrating network to reconstruct the input signal. The compandor may be used in conjunction with a digital integrating network which exhibits, for example, a system function, having either a single pole or a zero and a pair of poles which may be real or complex. The filter constants can be chosen to match any input spectrum to obtain optimum performance. A significantly high signal-to-noise ratio and a wide companding range have been obtained with the disclosed compandor. By providing storage elements in the compandor and in a digital integrating network and storing the calculated intermediate values, a plurality of input for output analog signals can be time division multiplexed and delta modulated with a single delta modulation system.
