Patent FI-982095-A (FI)
Inventor: IIVONEN JUKKA-PEKKA
IPC: G06F17/30
Filed: 1998-09-29
Abstract: The invention relates to a method for implementing a functional memory and to a memory arrangement. The memory is implemented as a directory structure comprising a tree-shaped hierarchy having nodes at several different hierarchy levels, wherein an individual node can be (i) a trie node associated with a logical table wherein an individual element may contain a pointer pointing to a lower node in the hierarchy, or (ii) a bucket containing at least one element so that the type of an individual element in the bucket is selected from a group including of e.g. a data unit or a pointer to a stored data unit. To optimize the performance of the functional trie structure, the trie nodes are implemented as quad nodes of four elements, and in at least part of the directory structure groups of successive quad nodes are replaced by compressed nodes in such a way that (a) an individual group comprising a given quad node and its child nodes is replaced by a node whose logical table has 16 elements, and (b) a compressed node known per se is formed from said node of 16 elements by physically storing in the node only non-nil pointers and in addition a bit pattern on the basis of which the physical storage location in the node, corresponding to the search word, can be determined. The invention also relates to a structure in which no buckets are used.

Patent GB-974061-A (GB)
Title: Aerated shortenings
IPC: A23D9/02
Filed: 1962-01-12
Abstract: Aerated shortenings are produced by subjecting a stream of chilled aerated liquid fat to a high pressure, e.g. 200-400 p.s.i.g., partially crystallizing the stream with agitation, suddenly releasing most of the pressure, e.g. to about 25 p.s.i.g., and then subjecting the fat to further crystallization with mechanical working in the presence of sufficient innocuous aerating gas to ensure that the product contains by volume 15% or more of the gas.  The pressure during the first crystallization stage is generally such that substantially all the gas present is in solution, and during the second crystallization stage is such that it is substantially all entrained or occluded rather than in solution.  Between the two crystallization stages the fat is preferably homogenized by passage from the high pressure side to the low pressure side of a constrictive orifice; the product is preferably packed immediately following the second crystallization.  The crystallizations are suitably carried out in a "Votator" (Trade mark) and a suitable fat blend consists of 90% partially hydrogenated soyabean oil, 6% fully hydrogenated cottonseed oil and 4% monodiglyceride emulsifier. Specification 786,488 is referred to.

Title: Improvements in or relating to electrical heating devices for buildings and the like
IPC: F24D13/02
Filed: 1940-01-22
Abstract: 614,385. Heating buildings electrically. MOSSIN, G. B. Jan. 22, 1940, No. 1298. Convention date, Jan. 16, 1939. [Class 39 (iii)] Buildings are heated electrically by means of resistance wire, strip, sheet or foil 4 applied to the face of fibre board 3, the opposite face of which is applied to the wall 1 of a room. The heating element may be covered by tapestry, paper, coating, or veneer 5 before application of the board 3 to the wall. The fibre board carrying its resistance may also be applied to a floor or ceiling. The resistance may be in the form of comparatively large strips of metal foil, or of zigzag strips. The supply voltage may be transformed down to 35 volts, and the heater may operate at a temperature below 30‹ C. According to the Specification as open to inspection under Sect. 91, the carrier sheet may be of asbestos cement, seaweed, glass wadding or cork, and the device may be -used as an independent heater. Alternatively, the resistances may be attached to a layer, or between two layers, of paper or cloth, which is then applied to the wall and may be coated with plaster. To control the heating, a thermal switch may be placed on the wall of a room to control the circuit or vary the voltage. Another thermostat may be subject only to the air of the room, and may control a damper or cooling device to ensure that the air temperature is below that of the walls, e.g., 14‹ C. and 22‹ C., respectively. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to stringed instruments
IPC: G10C3/26
Filed: 1920-01-15
Abstract: 138,323. Cloetens, G. J., Laloux, G., and Heyden a Hauzeur, L. M. C. A. van der. Jan. 28, 1919, [Convention date]. Pianofortes and stringed instruments, harmonics producing in; imitating other instruments.-The strings of pianofortes, harps, harpsichords, &c., are made to produce the octave, double octave, or other harmonic of the normal note, by mechanical damping under the control of the performer. An effect similar to pizzicato is obtained also by damping near the ends of the strings. Where there are more than one string to each note, as in a trichord piano, the component strings may be damped differently to produce various harmonics simultaneously. Fig. 1 shows the general arrangement, with supports 4, 4<1>, 4<11> for the dampers for the octave, doubleoctave, and pizzicato effects respectively. Fig. 2 shows a partial section at right angles to the strings 3, and Fig. 3 shows a section on the line AB, Fig. 2. The spring-supported dampers 8 are carried by the bar 5 supported by screws 6 from the spring-supported bar 4 which is moved to bring the dampers against the strings by means of a sliding wedge 9 operated by a rod 10. A wedge 12 may be used similarly to produce longitudinal movement when some of the component strings of a trichord are to be left undamped. Trichords may also be provided with separate damping arrangements for each of the component strings of the notes. The bars carrying the dampers may be arranged to be brought into action by turning upon a longitudinal axis instead of being pushed forwards by wedges. Instead of carrying separate dampers 8, the bar 5 may be provided with a projecting cord arranged longitudinally and covered with felt to bear upon the strings at the points required, or, as a similar alternative, the bar 5, Fig. 7, is provided with a semi-circular groove 21 covered by a diaphragm 22 which is kept inflated to form a projecting ridge.

Title: Improved method and apparatus for treating substances with electric discharges to facilitate chemical reactions therein
IPC: B01J8/42
Filed: 1938-05-09
Abstract: 502,063. Treating gases &c. with electric discharges. NYROP, J. E. May 9, 1938, No. 13782. Convention date, May 7, 1937. [Class 39 (i)] [Also in Group XI] For facilitating chemical reactions between substances, the reacting substances in the form of gases, vapours or solids in finely divided condition are led through arc or other electric discharges created by hurling solid or liquid particles at high speed and perpendicular to the path of the reacting substances between electrodes maintained at a high potential difference. According to one arrangement, the solid or liquid particles are ejected from a rotary atomizer against an annular member, which with the atomizer form the electrodes. The reacting substances are led in axially into the annular space and take a helical path through the field of the discharges between the particles and the electrodes and among the particles themselves. In another arrangement, the electrodes may. be spaced perforated plates. The particles are hurled at high speed between the plates, and the reacting substances are passed at right-angles through the perforations in the plates. The applications referred to are the production of ammonia from nitrogen and hydrogen; nitric oxide from nitrogen and oxygen ; ozone from oxygen ; sulphuric acid from sulphur dioxide, oxygen and water; water vapour from oxygen and hydrogen; acetylene, ethylene, oily products and soot from organic gases; cyanogen compounds from nitrogen and organic compounds; glyoxal from oxygen and acetylene ; the polymerization of oils the oxidation of mineral oils, cracking, voltolization and sterilization.

Title: Method and apparatus for determining communication in a  borehole between a perforated zone and a second zone
IPC: G01V5/08
Filed: 1973-01-11
Abstract: 1401712 Detecting faults in bore hole linings R R VANN 11 Jan 1973 1492/73 Heading G1A Faults 22 or 24, in the cement lining 14 between the bore hole casing 10 and the outside of the bore hole 8, which would allow oil to escape via faults 22 or 24 to other formations 23 or 25 instead of passing via perforation 20 into the bore hole, are detected by placing radio-active material (at positions 26, 36 outside and inside the lining 14) upstream and downstream of the perforation the radio-active material being soluble in water and/or acid and/or oil so that if cracks or faults are present the radio-active material will be "washed" into them and the presence length and direction of the cracks can then be detected by a radio-active counting device passed down the well. The interface 50, formed between the top of the cement lining or plug 14 and other mudlike material which may fill the upper bore hole annulus, may be detected by including radio-active pellets 51 in the cement slurry which is pumped in to form the cement lining 14, the pellets being of a density slightly less than cement and substantially greater than water so that they will come to rest in close proximity to the interface 50. A radio-active material of a different half life may be used at each position to provide more detailed information of the formation and direction of the faults. The radio-active material for the inside of the lining may be in pellet 26 form spaced around the collets joining adjacent pieces of casing, the material may be painted on, or it may be placed in a continuous groove around the outside of the collet Fig. 4 (not shown). The radio-active material for the outside of the lining may be incorporated in blocks 36 which are attached to the spaced apart bows of the casing centralizers 18, 118, 19 or they may be painted on the bows. The description also deals with methods of detecting defects and their remedy at various stages of the construction of cement lining section of the borehole.

Title: Digital to analogue converters
IPC: H03M1/00
Filed: 1974-04-03
Abstract: 1465890 Digital-to-analogue conversion EMI Ltd 3 April 1974 [12 Jan 1973] 1757/73 Heading H3H Steps, Fig. 2B, in the output of a digital-toanalogue converter 2, Fig. 1, are smoothed by the addition of a ramp waveform, Fig. 2D, whose individual ramps have gradients inversely proportional to the time intervals between the corresponding steps in the output of the converter 2. In Fig. 1, the steps are detected by a subtractor 5 receiving the digital input 23 directly and via a one sample period delay 4. The time intervals between steps are measured by counting clock pulses, the counts for each interval and a bit representing the sense (up or down) of the last step being transferred to a latch 11 at the same time as the converter 2 receives the step defining the beginning of the interval, delays 1 and 12 being equal. A digitalto-analogue converter 15 derives a D.C. signal of amplitude inversely proportional to the contents of the latch 11. If the last two steps were of like sense, detected at 13, the D.C. signal is integrated at 17, inverted or not according to the sense of the steps, and added at 3 to the output of converter 2. If consecutive steps are of opposite sense, no ramp is needed and a zero input is connected to the integrator 17. A limiter 18 limits the amplitude of the ramp signal to the equivalent of one quantizing step when a long interval between steps exceeds the capacity of the counter 9. The smoothed output at 24 may be an audio or video waveform. Modifications.-The signal for reading out store 10 into latch 11 may be derived in different ways; from the output of delay 1 via a delay/ subtract arrangement similar to 4 and 5 or a counter may be counted down to zero from the output of latch 11. The ramps may be approximated by staircase waveforms.
