Title: Circuit and method for operating high pressure sodium vapor lamps
Inventor: KACHMARIK DAVID J
IPC: H05B41/24
Filed: 1993-10-14
Abstract: CIRCUIT AND METHOD FOR OPERATING HIGH PRESSURE SODIUM VAPOR LAMPS                             ABSTRACT Circuits, and methods of using same, are disclosed for pulse operating a sodium vapor lamp and, in response to gating pulses applied to a resonant ballast, the lamp ignites to develop a quasi-resonant bidirectional current waveform through the lamp, the shape of which is controlled to suppress the excitation of acoustic resonant nodes in the lamp. The quasi-resonant bidirectional current waveform oscillates at a prescribed frequency and contains a first group of harmonics, the harmonic content of which is outside any acoustic frequency region associated with the lamp, and further contains a second group of harmonics having a harmonic content which coincides with such acoustic frequency region. The current waveform is caused to decay substantially at the time of ignition of the lamp to quickly reduce the magnitude of the second group of harmonics to thereby suppress excitation of the acoustic frequency region and prevent arc instability in the lamp.

Patent CA-2115947-A1 (CA)
Inventor: SMITH GREGORY C
IPC: G02B26/08
Filed: 1994-02-18
Abstract: ABSTRACT A method of fabricating debris intolerant devices 30, and especially micro-mechanical devices such as DMDs, that allows wafers to be sawn prior to completing all fabrication steps. Some devices are too fragile to allow cleaning operations to be performed after fabrication of the device. A solution is to saw and clean the wafers prior to completing the fabrication steps that make the device fragile. To prevent having to process the chips 30 individually, a substrate wafer 28 is attached to the backside of the dicing tape 24. This substrate wafer holds the sawn chips 30 in alignment allowing the remaining fabrication steps to be performed in wafer form.     TI-17394 Page - 10

Filed: 1992-10-19
Abstract: A system (10) for interlocking a plurality of modules (12, 14, 16; 104, 106), such as medical instrument modules (e.g., infusion pumps), in side-by-side relationship such that not more than one module (12, 14, 16; 104, 106) can be mounted on each side of a center module (14; 104). The modules (12, 14, 16; 104, 106) are interchangeable in that any module of the system (10) can be a center module (14, 104) or a side module (12, 16; 106). In the preferred embodiment, latching arms (20, 22) on a module (14) are automatically moved as the module (14) is mounted on a pole stand (17) to allow other "side" modules (12, 16) to be mounted on that "center" module (14). The latching arms (20A, 22A, 20B, 22B) of the "side" modules (12, 16) prevent additional modules from being mounted on the side modules (12, 16). Other embodiments are described as well.

Title: Defluorination of phosphoric acid
Inventor: HUTTER KLAAS J
IPC: C01B25/234
Filed: 1994-05-16
Abstract: Fluorine  in  the  form of fluoride is removed from  phosphoric  acid  having  an  initial phosphate concentration  of  less  than  about  50  percent  by determining  the  concentration  of  fluoride  to  be removed  from the  acid  and  the  concentration  of silicon  in the acid.  Silica is added to the acid in an   amount   sufficient  that  the  molar  ratio  of fluoride  to  be  removed from the acid to silicon in the  acid  is about 6.  The acid is concentrated to a final  phosphate  concentration of greater than about percent,   whereupon   fluoride  is  reacted  to fluosilicic  acid.    By  maintaining  the  indicated concentration  ratio  of  fluoride  to be removed and silicon,    fouling   of   condenser   and   scrubber components with deposited silica is avoided.

Title: Snap-On, Flexible Lid
Inventor: VON HOLDT JOHN W SR
IPC: B65D43/02
Filed: 1994-06-07
Abstract: A snap-on  flexible  lid  for  a  container comprises a flat lid face and an annular, peripheral flange extending normally of the lid face to enclose and grip an annular lip of a container.  The term "annular" is intended to include all closed loops,  for example those of rectangular containers.  The flange comprises spaced panels angled inwardly from the remainder of the flange to engage the underside of the container lip.          This promotes retention of the lid on the container and permits a container where the flange is essentially free of circumferential tear lines, avoiding problems of lid pop-off, and undesired tearing of the circumferential tear lines in the event the container is dropped.  The angled panels  are  defined  between pairs  of  cutting apertures  to permit  the  separation  of  the  sections defining the panels by a pair of vertical cuts,  for opening of the container.

Patent CA-2132572-A1 (CA)
Title: Completely fabricated pipe sleeve assembly
Inventor: EATON DELBERT H
IPC: F16L55/172
Filed: 1994-09-21
Abstract: By using fabrication procedures, which do not use any casting, a pipe sleeve assembly, or a pipe sleeve assembly with additional components, is made for installation on a pipeline.          When the pipeline is made of plastic pipes and this pipe sleeve assembly is fully tightened, there is acceptable limited radial deflection of the cross-sectional portions of the plastic pipe, being sealed by the surrounding gasket held in place by the assembled fabricated parts and the bolt and nut fasteners.  On opposite sides of each separating gap of the sleeve, side bar and lug units are welded to the sleeve.  Between opposite lugs, independently removable bolt and nut fasteners are secured.  In one embodiment, the opposite lugs both have holes, which are aligned to receive and to hold portions of a bolt.  In another embodiment, one of the opposite lugs has a hole, and the other opposite lug has spaced portions thereof, each having an overlapping lip portion, which receive a drop in bolt portion located near the head of the bolt.  The bolt is then moved, so the bolt head is located under the overhanging lip portions.          During these motions the bolt has another portion arranged within the hole of the opposite lug.  Upon tightening of the respective nuts, the respective independently removable bolt and nut fasteners are secured in place holding the sleeve sections together.  These embodiments are fabricated from stainless steel.     Also these embodiments are fabricated from mild steel, bronze and other metals.  While the independently removable bolt and nut fasteners are kept well clear, the other fabricated parts have their respective surfaces treated by: impacting blasting particles; chemical treatments, such as passivation; and/or coated as required.  These treatments of the sleeve are undertaken independently of the bolts and nuts.  Therefore, the bolts and nuts may be derived from various materials, and the other sleeve components may be derived from various materials.

Title: A dual mode cellular modem
Inventor: SCOTT ROBERT E
IPC: H04L29/08
Filed: 1994-10-24
Abstract: A mobile phone includes a modem, hereinafter referred to as a cellular radio modem. This cellular radio modem supports two modes of operation - an analog mode, where the cellular radio modem provides an analog signal for transmission; and a digital mode, where the cellular radio modem provides a digital bit stream for transmission. During operation, i.e., the existence of a data connection to a far-end modem, the cellular radio modem is alerted by the cellular network to switch to the appropriate mode?analog or digital. The cellular radio modem then switches and continues transmission in the new mode. In this embodiment, the far-end modem is part of a modem-pool located within the Mobile Telecommunications Switching Office of the cellular network. The far-end modem automatically detects this switch by the cellular radio modem and itself switches to the appropriate mode. This allows a mobile data user to transparently move between the analog mode andthe digital mode without disconnecting a preexisting data connection.
