Patent GB-606077-A (GB)
Title: Well packers
IPC: E21B33/12
Filed: 1946-01-10
Abstract: 606,077. Well packers. McGAFFEY, E. W., and TAYLOR, C. C. Jan. 10, 1946, No. 889. Convention date, Jan. 30, 1945. [Class 85] In a well-packing tool the pressure of the entrapped fluid below the tool, instead of opposing the weight of the drill string is used to exert a downward force, so assisting the expansion of the slips. The tool comprises a body 2 containing a mandrel 4, which has a limited freedom of movement in both axial and radial directions. Relative axial movement between the mandrel and the body will cause the slips 11 to expand and grip the well casing 3, a lost motion connection 15 being provided between the mandrel and the slip head 13. The lower portion of the tool carries the packer means 31, 32 and consists of two chambers 42, 43 in which move pistons 38, 40, attached to the mandrel. In lowering the tool the mandrel is locked in position with respect to the body by a pin 23, so that the slips are withdrawn in the bowl 9, whilst the pressures above and below the tool are equalized by a byepass formed by an opening 46, chamber 43 and opening 45. When the desired depth is reached, the mandrel is unlocked by rotating it, and it then falls a short distance expanding the slips and closing the byepass. The packing means operate when the pressure below the tool is increased and this pressure acts on the top of piston 40 and on the underside of piston 38. The pressure on the other sides of the pistons is that acting above the tool, it acting through the passage 46, chamber 43 and passage 47. Because piston 40 is larger than piston 38 the resultant upthrust due to the fluid below the tool is diminished. Specification 600,341 is referred to.

Title: Improvements in or relating to tape web transport mechanisms
IPC: G06K13/30
Filed: 1966-01-10
Abstract: 1,134,324. Tape web transport mechanisms. R. D. LACY. 10 Jan., 1967 [10 Jan., 1966], No. 996/66. Heading G5R. For moving a paper tape W for punching or reading in discrete steps of predetermined length at high speed, a knurled pinch roller 34 mounted on a rocker and having spaced longitudinal grooves is rocked about a knife edge 31 by the energization of coils 30, whereupon the roller holds the tape against a continuously rotating capstan 9 for movement therewith, until the roller has turned from an initial position to a position in which a groove opposes the capstan, so that tape movement ceases. The coilenergizing current can then be switched off. There are several angular " initial " positions for the roller when it is free of the tape: these are predetermined by a device including a toothed detent wheel mounted on the end of the roller shaft. After switch-off a resiliently-biased detent arm indexes the detent wheel, and hence the pinch roller, to the nearest initial position. The detent arm has an eccentric mounting by adjustment of which the starting position of the pinch roller, and hence the precise amount of paper movement, may be adjusted. The circumferential spacing of the grooves is preferably greater than the incremental tape movement by at least half a groove width; but when the spacing is exactly twice the tape movement, the tape may be stepped in either direction. Where, as shown, the tape is read by star wheels 16 or the like, the tape may have sprocket holes punched down each edge to engage with resiliently-controlled sprocket wheels 6, close to the star wheels, to ensure constant reading registration.

Title: Code excited linear predictive vocoder and method of operation
Inventor: KETCHUM RICHARD HARRY
IPC: G10L25/93
Filed: 1993-09-16
Abstract: Apparatus (101-112) for encoding speech using an improved code excited linear predictive (CELP) encoder (106, 104) using a virtual searching technique (708-712) to improve performance during speech transitions such as from unvoiced to voiced regions of speech. The encoder compares candidate excitation vectors stored in a codebook with a target excitation vector representing a frame of speech to determine the candidate vector that best matches the target vector by repeating a first portion of each candidate vector into a second portion of each candidate vector. For increased performance, a stochastically excited linear predictive (SELP) encoder (105, 107) is used in series with the adaptive CELP encoder. The SELP encoder is responsive to the difference between the target vector and the best matched candidate vector to search its own overlapping codebook in a recursive manner to determine a candidate vector that provides the best match. Both of the best matched candidate vectors are used in speech synthesis.

Title: Laser beam scanner
Inventor: YAMAGUCHI NAOTO
IPC: H01S3/00
Filed: 1992-01-06
Abstract: PURPOSE:To carry out stable welding with a slight Coriolis force by condensing and reflecting a laser beam and irradiating a weld zone with this beam by a reflection surface which receives the laser beam with a tapered rotary mirror. CONSTITUTION:The laser beam L1 is reflected by a concave mirror 11 to form the laser beam L2. This laser beam is reflected by the rotary mirror 12 to form the laser beam L3 which is cast as a spot S onto a work. The reflection surface tea of the rotary mirror 12 inclines by an angle theta with a revolving shaft 13a and, therefore, the spot S deviates by a radius (r) from the axis O2 of the laser beam L3 as the rotary mirror 12 rotates. Since the spot S rotates at the prescribed radius (r) around the weld zone of the materials to be welded, the welding position and the size of the spot S do not change and the stable welding is executed even if the laser output is large. Only the rotary mirror 12 rotates and, therefore, the Coriolis force by the movement of a housing 10 is just slightly necessitated.

Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To always stably treat a hydrogen-contg. waste gas by connecting a hydrogen-contg. waste gas discharge source to the suction port of an ejector type vacuum generator and an oxygen supply source to the driving fluid supply port of the vacuum generator and providing a hydrogen-oxygen reaction furnace provided with a catalyst to the driving fluid discharge port of the vacuum generator and a drain tank to the outlet of the reaction furnace. SOLUTION: A prescribed flow rate of O2 is supplied from an O2 supply valve 16 to the driving fluid supply port 7a of a vacuum generator 7, the suction port 7b of the vacuum generator 7 is evacuated and a control valve 14 is opened to suck a hydrogen-contg. waste gas G from a hydrogen annealing furnace 2 into the vacuum generator 7. The waste gas G accompanied by the O2 supplied from the O2 supply valve 16 is introduced into a reaction furnace 5, diffused and charged into the main body of the furnace 5 on the outlet side. The hydrogen and oxygen in the mixed fluid are brought into contact with a hot coating film of a platinum catalyst on the surface of the inner wall of the body of the furnace 5 to be converted into radicals and allow them to react with each other to produce water.  The produced water becomes steam, the resultant steam, together with the residual O2 , is discharged into a drain tank 9 connected to the reaction furnace 5 and the steam is condensed and stored as water. Thus, the waste gas G can be completely treated even if the flow rate and hydrogen concn. of the gas G vary.
