Patent IE-801459-L (IE)
Title: Making packaging tubes.
IPC: B29C48/09
Filed: 1980-07-11
Abstract: A blank is formed out of plasticizable, heated plastic by means of an extruding-type material supply head. A somewhat lenticular profiling of the blank is obtained by appropriately controlling a closing member of the material supply head, which is built as a valve cone. When the closing member is closed off against the lower edge of a tube part of the material supply head, the blank is pinched off from the material supply. A flow of air emerging from a ring nozzle serves to ensure complete severance of the blank from the material supply head. After that has been accomplished, the blank enters an open shaping cavity of a die by free fall. By further movement of the die, which is located on a rotary table, the die removes itself from the permanently located material supply head, so that the blank lying in the cavity can be pressed into a molded article by a stamp. Cooling off too much in certain locations on the blank is prevented by the free fall of the blank into the shaping cavity.

Title: Non-destructive testing of brazed butt joints
IPC: G01N29/04
Filed: 1979-08-08
Abstract: A non-destructive method of testing for defects in brazed joints in metallic articles such as hollow copper electrical conductors comprising subjecting the joint (2) to a tensile force which is greater then the yield strenght of the metal of the metallic article (1) across the brazed joint (2) and thereafter passing a X-ray beam or an ultrasonic pulse through the brazed joint (2) to detect any gap which has been formed at the brazed joint (2) by the application of the tenside force. X-ray and ultrasonic testing of brazed joints does not reliably detect all defects in brazed joints, particularly butt joints, which might later result in failure of the joint under stress. The application of the afore-mentioned tensile force exposes such defects by creating a significant gap at the joint which is detectable by X-ray or ultrasonic test.

Title: Method of and apparatus for extracting juice and meat from a¹fruit
IPC: A23N4/18
Filed: 1989-12-29
Abstract: A method of and apparatus for extracting the meat section and juice from a fruit while minimizing the amount of undesirable flavor components, e.g. peel oil, released from the fruit's peel. In one embodiment of the present invention, whole fruits are fed into a single station extraction apparatus (10) that first cuts a equatorial groove in the fruit's peel while the fruit is rotated. A semicircular coring blade (170) is then inserted into the groove and rotated 360 DEG which severs a spherical chunk of fruit meat from the peel. The small amount of fruit meat remaining on the peel's inner surface is then preferably extracted with a reaming element (200) or fluid jet nozzle. In other particularly preferred embodiments, the grooving, coring, and reaming component mechanisms are incorporated into an indexing turret apparatus and a high-speed continuous motion turret apparatus.

Abstract: A heat-insulating body such as a heat-insulating slab is made whose insulating and heat-absorbing material includes a fine powder, in particular a silica aerogel which is pressed to form the body. To carry out the pressing operation a sack-like sheath is required but between the sheath and the insulating material a separating agent is provided which results in the fact that the surface of the insulating material does not intimately engage with the sheath which is for example of glass fibre fabric, the sheath being movable with respect to the insulating material after the pressing operation. Apart from the fact that the sheath can be removed for any cases where it would be a cause of disturbance, additionally the insulating body provides improved bending properties and even when made with a high pressing rate has a homogeneous structure. To make the insulating body the separating agent may be applied to the inner surfaces of the sheath, the particulate insulating material then being introduced and the sheath sealed, whereafter pressure is applied.

Abstract: A process, and a device for carrying out the process, is provided for coding pulse-amplitude modulated signals into PCM signals in accordance with an approximated logarithmic characteristic curve. In the process, a partial coding characteristic curve which possesses a substantially reduced dynamic scope is first produced in a known manner. In accordance with the invention, a second pre-decision is carried out which subdivides the dynamic region of the partial coding characteristic curve into two sub-regions in such a manner that the coding of the lower and upper sub-regions is effected with the same number of weighting steps. This saves one weighting step with respect to prior processes.

Inventor: JONES JAMES E
IPC: C12Q1/00
Filed: 1986-06-11
Abstract: Polymerizable silicon-containing compounds are polymerized or further polymerized in dispersed form to form cured layers or membranes when cured or polymerized in a dispersed layer upon removal of the continuous phase during curing to provide a layer or membrane having unexpectedly good oxygen and glucose-permeability without allowing the passage of electrode-sensitive interferants therethrough. The membranes also are permeable to cholesterol, uric acid, and lower alcohols, such as ethanol. The polymerizable silicon-containing compounds, after dispersion in a continuous phase, such as by including an emulsifier, can be cured in any known manner during removal of the continuous phase, such as by evaporation of water from a water-continuous phase silicon emulsion or dispersion. A glucose catalyst layer, such as glycose oxidase, can be bonded directly to an electrical, signal-receiving surface, such as an electrode, and the membrane applied over the catalyst to form an electrochemical sensor having new and unexpected accuracy. Whole blood is applied directly onto the membrane, allowing passage of glucose and oxygen to the glucose oxidase layer while preventing passage of substantially all other electrode interferants present in whole blood. The glucose and oxygen interact with the glucose oxidase catalyst to produce hydrogen peroxide which is received immediately by the electrode surface. Since the membrane is whole blood compatible, at the conclusion of the measurement, the whole blood on the surface of the membrane may be rinsed or wiped off and the sensor is ready for measurement of another specimen.
