Title: Compact fluorescent lamp and base combination, and method of lamp-base assembly
Inventor: WITTMANN HORST
IPC: H01J5/50
Filed: 1991-04-19
Abstract: To simplify assembly of a bottom portion (4) with a cap portion (3) of a base to a compact fluorescent lamp, and permit automated assembly thereof, the cap portion is formed with inner axially extending projections (23-26), and current supply leads (27a-28b) are looped about the axially extending projections. A circuit board (8) located transversely across the bottom portion (4) has essentially U-shaped bow frames or arched or clip elements (35-38) located thereon which are positioned to engage by resilient surface contact with the end portions (31) of the current supply leads when the bottom portion and the cap portion are snapped together upon axial movement. Inwardly extending ribs (44, 45; 48, 49) projecting from the inner wall of the bottom portion support the bow frame or arched or clip elements, and ensure prestressed reliable contact engagement between the bow frame or arched or clip elements and the end portions of the current supply leads. Preferably, the end portions of the current supply leads and of the clip elements are made of tinned wires.

Inventor: MARU TSUGUO
IPC: H04W88/02
Filed: 1991-04-25
Abstract: A security module for a radio telephone prevents a KEY code stored in a non-volatile memory from being read out for illicit use. The security module deletes the KEY code stored in the memory when accessed from the outside.  Hence, although a KEY code can be written to the memory or the operation of the memory can be tested from the outside, the KEY code is prevented from being read out by an unauthorized person.

Patent CA-2043787-A1 (CA)
Title: Enclosure for slag pelletization apparatus and method of operation thereof
Inventor: SPENCER KENNETH W
IPC: C21B3/08
Filed: 1991-06-03
Abstract: The invention provides a new enclosure for slag pelletizers, and a new method of operating such an enclosure, that minimizes the noise and the escape into the ambient atmosphere of hydrogen sulfide and airborne particulate material produced by the pelletization. The enclosure consists of impermeable walls and a roof, the pelletized material being removed through an openable door at one end that is closed during the process. The enclosure has three successive zones, in the first of which contains the pelletizer, this being supplied with only the amount of water needed for pelletization. In the second zone containing the slag pile a plurality of very fine mist producing nozzles supply water to the gases to cool them using its latent heat of evaporation, the amount of water supplied being such as to cool them as much as possible while being limited so that it all remains vapourised and cannot enter the slag pile to increase its moisture content. In the third zone the quantity of water supplied is sufficient to condense the water vapour, entraining the soluble hydrogen sulfide and the particulate matter. The condensed water and entrained material is removed and treated, preferably with waste alkaline water, to stabilize the hydrogen sulfide, remove the particulate material, and recycle the water. The non-condensible gases exiting from the top of the third zone can pass through a chimney to the atmosphere or to a gas scrubber for further scrubbing.

Title: Speech coding system
Inventor: TANIGUCHI TOMOHIKO
IPC: G10L19/10
Filed: 1991-06-17
Abstract: A speech coding system operated under a known code-excited linear prediction (CELP) coding method. The CELP coding is achieved by selecting an optimum pitch vector P from an adaptive codebook and the corresponding first gain and, at the same time, selecting an optimum code vector from a sparse-stochastic codebook and the corresponding second gain. The system of the present invention is featured by special code vectors to be loaded in the sparse-stochastic codebook, which code vectors are hexagonal lattice code vectors each consisting of a zero vector with one sample set to +1 and another sample set to -1.

Title: Processing unit
Inventor: GLOVER EDWARD C T S
IPC: G03D3/13
Filed: 1990-02-01
Abstract: The critical time in photographic processing apparatus is the time from when the first part of photographic material enters the apparatus to when the last part leaves the apparatus. During this time there are periods of time in which no processing takes place, for example, as the material is passed from one stage to the next. Described herein is a processing unit which minimises the periods of time during which no processing is taking place. The unit comprises a processing tank (6) having processing solution (4) retained therein. Material (S) is fed into the tank (6) along a path (2), and around a looped path (8) until reaches a point (10) at which the material (S) can be deflected out of the tank (6), along path (14) and into a further processing tank (16), or can be deflected along path (12) so that further processing can take place in tank (6) prior to being passed on to the next stage.

Title: Apparatus and method for detecting contraband using fast neutron activation
Inventor: GOZANI TSAHI
IPC: G01N23/222
Filed: 1991-01-09
Abstract: An apparatus and method non-invasively interrogates an object (134) to detect contraband. The ap-paratus irradiates the object (134) with fast neutrons of energy greater than 6.7 MeV, and measures the ensu-ing gamma-ray spectra. Irradiation of the object is accomplished by produ-cing a neutron beam (132) and mov-ing the interrogated object stepwise or continuously relative to the beam.      The nuclear interactions of highly penetrating neutrons within the irra-diated volume of the object give rise to energetic nuclear-species character-istic gamma-rays. The energy and intensity of the emitted gamma-rays provide information relative to the spatial arid density dis-tributions of the gamma-ray sources, i.e., the specific atomic nuclei within the object. From this information, three-dimensional images of the atomic nuclei spatial and density distributions are inferred.  Such three-dimensional images allow a decision to be made as to the presence of contraband. Measurements are made using arrays (144) of gamma-ray scintillator detectors. A deci-sion analysis based on statistical methods (e.g., discriminant analysis) or an artificial neural system, or other expert system, facili-tates a low false alarm rate. One embodiment of the apparatus includes neutron beam collimator means (136) to define and limit the irradiation volume of the objet, and auxiliary neutron shielding means (135) to attenuate the neutrons in other than desired neutron beam direction(s). Another embodiment includes an X-ray system (150) and combines electron density information ob-tained from an X-ray image of the object with the spatial and density distribution information of the gamma-ray sources in order to further enhance the decision analysis.

Title: Semiconductor device comprising a layered structure grown on a structured substrate
Inventor: BONA GIAN-LUCA
IPC: H01S5/00
Filed: 1992-03-02
Abstract: ABSTRACT       Semiconductor device (30) such as a laser diode grown on a structured substrate surface having horizontal regions with adjacent inclined sidewall surfaces: the horizontal regions (32o) of standard orientation like (100) or slightly off, the inclined surfaces (32m) misoriented. The layers (33 to 36) forming the device are grown over the structured surface, at least the active layer (34) being of a semiconductor material that assumes ordered or disordered states depending on the orientation or misorientation of the substrate surface. The center section (34a) of the active layer is deposited over a horizontal substrate region (32o), this section thus being in the ordered state and having a lower bandgap energy than terminating sections (34b) grown on inclined substrate regions (32m), therefore having a wider bandgap. The active layer can be terminated in either lateral direction with wider bandgap material whereby devices of a buried structure, with strong carrier confinement, and/or with non-absorbing mirrors, allowing high optical power operation, can be realized.
