Patent GB-672320-A (GB)
Title: Improvements in or relating to the production of sulfuric acid
IPC: C01B17/74
Filed: 1950-01-11
Abstract: <PICT:0672320/III/1> Sulphuric acid is produced by introducing sulphur trioxide-containing gases into and below the surface of a body of boiling sulphuric acid, the heat of absorption of the sulphur trioxide being removed as latent heat of vaporization by active boiling of the sulphuric acid, agglomerating and condensing the sulphuric acid mist and forming dilute acid therefrom, and returning to the body of boiling acid sufficient dilute acid to provide both the water necessary to form sulphuric acid with the sulphur trioxide and the water removed from the absorbing acid by boiling.  The sulphur trioxide need not be precooled, its sensible heat being removed by the boiling of the acid.  In the Figure, sulphur trioxide entering at 5 passes into a high stage absorber 2 containing boiling sulphuric acid above 70 per cent concentration, the vapours of which, acid mist, water vapour and unabsorbed gases pass via 7 and 8 to a low stage absorber 1 conaining boiling sulphuric acid of less than 70 per cent concentration.  The vapours effluent at 9 from this absorber, consisting of acid mist and water vapour are contacted with a stream of water or dilute acid in the throat 11 of the venturi 10, the resultant dilute acid passing through pipe 13 to a container 14. The residual gases are scrubbed in 16 by water jets 17 supplied by pipe 24 and the resulting dilute acid passed via pipe 19 to the container 14 from which the acid is pumped to union 23 and distributed to pipes 24 and 12 and also via pipe 25 to the low stage absorber 1.  The latter is connected by pipe 26 to absorber 2 from which the product leaves through 27.  If desired, only one absorber may be employed, in which case, if an acid of under 70 per cent strength is required, the venturi can be eliminated.  If an acid of over 70 per cent strength is required the venturi is employed to condense both the acid vapours and acid mist.  In this case the sulphuric acid recirculated through container 14 should have an acid content equivalent to that maintained in the low stage absorber in a system where two or more absorbers are employed.

Patent HK-17295-A (HK)
Title: Digital vertical beam landing correction circuit
Inventor: BOLGER THOMAS VINCENT
IPC: H04N3/23
Filed: 1995-02-09
Abstract: Vertical beam landing errors in color cathode ray tubes are corrected by a digital delay circuit (20) which provides horizontal scan line video pixel information at its proper location to produce a distortion corrected raster. Accurate correction is provided by sample interpolation techniques (31, 32, 37) that effectively form derived pixels that have an apparent location between scan-lines that corrects the scanning distortions. The location of the derived pixel relative to the video pixel samples can be determined by the selection (34, 35) of the interpolating coefficients. Such correction is preferably combined with a scan line offset technique (34, 30) providing a coarse correction.
Patent HK-50788-A (HK)
Title: Synchronisation of electrical oscillators
Inventor: FALCONER ROBERT MCKENZIE
IPC: H03L7/06
Filed: 1988-07-07
Abstract: A modification of a phase-locked loop comprises incorporating a variable delay element in the feedback path from the oscillator to the phase comparator. The delay is controlled by the signal at the input to the oscillator, and allows two phase-locked loops having different input delays to be interconnected and such that they stabilise at a common frequency. This arrangement may be used in a network of interconnected oscillator terminals to allow the terminals to synchronise even when only indirect paths exist between them. It is therefore highly fault tolerant.

Title: Method and device for authentication communication
Inventor: SHIMIZU KAORU
IPC: H04L9/32
Filed: 1999-01-05
Abstract: PROBLEM TO BE SOLVED: To obtain an authentication communication method and device whose safety is guaranteed in principle by the uncertainty principle of quantum mechanics. SOLUTION: A transmitter receives an ID number from an authentication agent 1, generates an information carrier encoded from significant information bits and an information carrier encoded from ID information bits by using a grain or a grain group having four or more internal states of quantum mechanics intersecting with each other at right angles as an information carrier and transmits all information carriers obtained by inserting ID information bits into a significant bit string at random to a receiver. The receiver receives all the information carriers, obtains measured results and reports the transmitter of some measured results in accordance with a transmitter's request. After checking the receiver's measurement, based on these measured results, the transmitter discloses the inserted positions of the ID information bits.  The receiver decodes the significant information bits, based on the inserted positions of the ID information bits, obtains document information and inquires of the agent 1 to ID information bits to collate whether the transmitter is the person himself (or herself).

Filed: 1985-01-09
Abstract: PURPOSE:To make easy the control at the time of the trouble by selecting other transmitting and receiving ends and executing the communication by a transmitting signal which passes through a coupler, when abnormalities occur to communication. CONSTITUTION:While communication is going on using a transmission line 11, receiving transmitting edges A of respective devices 21-2n as 'in-use' devices, disconnection, etc., occur at the mark X of the transmission line 11, the communication between devices 21-22 and devices 23-2n goes to be abnormal, and when the devices 21 and 22 detect this, these devices only select receiving transmitting edges B. Then, a transmitting route between the devices 21 and 22, and the devices 232n is formed through a transmitting line 12, a coupler 3 and the transmitting line 11, and an ordinary communicating condition is maintained. Besides this, since the transmitting from the receiving transmitting edges A is received and the transmitting and receiving can be executed in the opposite direction, the self-checking by a loop-back through transmission line 11 and 12 can be always executed.

Title: Noise reducing device for automobile
Inventor: AKAIKE IKUMORI
IPC: F01N1/02
Filed: 1995-01-09
Abstract: PURPOSE: To effectively reduce noise in an intake system by a system which is inexpensive and excellent in durability by connecting a capacity chamber having a prescribed capacity to the way of an intake passage through a duct, and variably controlling the opening area of the duct. CONSTITUTION: A resonant type muffler 10 is connected to an intake duct which is provided between an air cleaner 2 and an air flow meter 7. The resonant type muffler 10 is formed in such a way that a capacity chamber 11 having a prescribed capacity and the intake duct 3 are connected to each other through a duct 12 having a prescribed diameter and length, and a linear solenoid valve 13 is interposed in the duct 12 as an opening area varying mans for changing the effective opening area. The capacity of the capacity chamber 11 and the length and the diameter of the duct 12 are decided on the frequency belt range of noise in which reduction is demanded beforehand, and linear solenoid valve 13 is drive-controlled by a control unit 14 on the basis of output of a microphone 15 as an intake noise detecting means so as to obtain the belt range of necessary resonant frequency.  It is thus possible to control the opening area of the duct 12.
