Patent EP-0090503-A2 (EP)
Inventor: ORCUTT JOHN W
IPC: H01L23/28
Filed: 1983-03-01
Abstract: A method of packaging a semiconductor device during which leads (312, 313) are lanced from a bar pad (3/7) of the ead frame (310). The leads (312, 313) of the lead frame (310) remain within one plane and the bar pad (317) is displaced to a different plane in order to provide the necessary separation between the ends of the leads (312, 313) and the bar pad (317) to prevent accidental connections. A region of reduced mechanical strength is provided laterally across each lead to allow the leads to be bent after the smiconductor device and the portions of the leads adjacent to the semiconductor device are encapsulated with a plastic enclosure. At least some leads have an enlarged area within the encapsulated portion of the leads to secure and anchor the leads within the plastic forming the encapsulating enclosure.

Abstract: A pesticidal composition comprises a pesticide, a solvent and a foaming agent. Preferably the composition is packed in a pressurised can with a hydrocarbon propellant and a suitable valve. Such compositions may be sprayed onto all or part of an animal, particularly a pet, and the resulting foam collapses rapidly to deposit the pesticide onto the animal, thereby avoiding disdvantages of run-off. The pesticide may be a pyrethroid or organophosphate. The foaming agent may be a waxy material, for example a mixture of higher fatty alcohols and a surfactant.

Abstract: In a system for optimizing the control of the water temperature within a cooling tower (10), the temperature (T AIR ) and the relative humidity (RH AIR ) of the air outside the cooling tower are measured and are selectively utilized as inputs to a plurality of modules (20, 22) containing function blocks in a logic arrangement. The function blocks produce an output signal (T wet bulb ) indicative of the wet bulb temperature of the outside air, which signal is compared with the cooling tower water temperature (T cT ) causing the speed of fans of the cooling tower to be adjusted in response to the temperature difference therebetween.

Abstract: Vital gluten is disclosed having an enhanced content of monoglycerophospholipid e.g. 30 mol % or more of the total phospholipid content, as well as processes for the production thereof and use thereof as an improved food improving agent. The novel vital gluten is obtained by enhancing the monoacylglycerophospholipid content relative to the diacylglycerophospholipid content, e.g. by treating the wheat flour dough used to obtain the vital gluten, with phospholipase A thereby to convert endogenous diacylglycerophospholipid enzymatically into endogenous monoacylglycerophospholipid. Further enhancement can be obtained also by adding exogenous mono or diacylglycerophospholipid to the dough.

Abstract: The present invention relates to an electrotherapy apparatus in which both low-frequency magnetic fields with frequencies below 30 Hz as well as high-frequency electromagnetic fields with frequencies of in particular above 100 kHz, preferably 1 MHz and over, are used. In a therapy apparatus functioning with heating of the tissue, according to the invention an applicator for radiation heating the tissue, in particular a microwave applicator, is combined with a low-frequency applicator for a low-frequency electromagnetic alternating field. In a therapy apparatus for induction of a low-frequency alternating voltage in a pick-up coil connected to tissue electrodes, the high-frequency oscillations are in contrast of such low intensity that they cannot effect any significant heating of the tissue, but they are nevertheless modulated with the low-frequency oscillations. In this way, the induction of low-frequency currents in implants can be effected with lighter external coils. <IMAGE>

Abstract: The invention relates to a process for adsorption of nitrogen from nitrogen-containing gases using faujasite-containing compositions in which the original hydrogen or monovalent forms are ion exchanged to their polyvalent form and then dehydrated in such a manner as to result in a pre- ponderence of its polyvalent ions in a dehydrated/dehydroxylated state while maintaining substantially the same zeolite content. The resulting compositions, whose cations contained in the faujasitic portion are substantially in their dehydrated/dehydroxylated state, have been found to have surprisingly high selectivities and capacities for the separation of air into nitrogen and oxygen.

Abstract: Provision is made for identifying tools used in an automated machine tool system. A module or transponder is mounted to the tool and interrogated by a transceiver which, in the preferred embodiments, has read/write capabilities. The transponder uses energy from the transmitted signal to power itself and send information stored in its memory back to the transceiver. In one embodiment, electromagnetic energy is transmitted from the transceiver to the transponder while the transponder to transceiver communication link is provided by way of capacitive coupling. In another embodiment data is communicated bi-directional through modulated optical signals while power to the transponder is sent from the transceiver through an electromagnetic coupling.
