Title: Learning aid or game having miniature electronic speech synthesizer chip
IPC: G10L13/047
Filed: 1979-04-23
Abstract: An electronic hand-held, talking learning aid 1 is disclosed. The learning aid includes an MOS speech synthesizer chip having an active surface area of the order of 45,000 square mils. The speech synthesizer chip includes a digital filter, a voiced/unvoiced excitation circuit, a speech parameter interpolator, an input parameter decoder, a digital-to-analogue converter and associated timing circuits. The learning aid is also provided with a micro-processor which functions as a controller for controlling the operation of the unit. A small speaker is driven by the digital-to- analogue converter on the speech synthesizer chip and a keyboard 3 and a display 2 are strobed by the microprocessor controller. In a first, spelling, mode, a question is posed via the speaker and an answer entered via the keyboard by the operator is compared with the correct answer, a resultant response being given via the speaker. In a second mode the operator is shown a word via the display and asked to speak it; after a delay the correct pronunciation is produced by the learning aid via the speaker. In a third mode, a word is selected for display, but certain letters are omitted, leaving the operator to complete the word. In third and fourth modes, respectively, encoding/decoding of words and generation of a random word are performed. <IMAGE>

Title: A reference voltage source
IPC: H03M1/36
Filed: 1979-09-03
Abstract: An integrated circuit reference voltage source comprises two MOS transistors T1, T2 of the same conduction type connected in series across a supply U2. The gates of the transistors are connected together and to the drain of one transistor T2. The substrates of the transistors T1, T2 are also connected together, and the drain-to-source voltage U1 of the other transistor T1 represents the reference voltage. This may be compared with the output of a series MOS transistor regulator, to regulate the output voltage (Figure 5A not shown). The transistors are adapted to operated in weak inversion and provide a reference voltage which is proportional to the absolute temperature and further depends practically only on the dimensions of the transistors. <IMAGE>

Title: Solenoid Operated Shut Off Valve with Manual Reset Valve
IPC: F16K31/40
Filed: 1979-12-21
Abstract: A solenoid operated stop valve with manual reset comprises a Main Stop Valve 7 having a partially balanced valve member 7 biassed to the closed position by inlet pressure acting in chamber D on a piston part 6 of the stop valve 7. Pressure to the piston is controlled by a Solenoid Valve 11 which can either pass inlet pressure to the piston 6 or vent the piston pressure through a first vent via seat 10. A fully balanced Reset Valve 1 having two seats 4, 5 and which is spring loaded on to its first seat 5 to seal a second vent F is arranged such that when the main valve 7 opens the reset valve 1 is tripped off its seat by the piston 6 to a mid seat position to vent the chamber D through the second vent. The main valve 7 will now remain open regardless of solenoid valve action. Reset to the main valve closed condition is effected by pulling the valve 1 onto its second seat 4 to close the second vent 7. <IMAGE>

Title: Process for obtaining hulupones from lupulones
IPC: B01D11/02
Filed: 1980-05-19
Abstract: A process for obtaining hop extracts comprises adding adsorbents to hop products which contain alpha-acids and ground, crushed or ruptured lupulin seeds, or such hop products which are in the form of extracts, treating the mixture obtained with CO2 in a closed pressure vessel at a supercritical temperature and under a pressure of from 50 to 600 bars, reducing the pressure of the CO2 leaving the pressure vessel whereby a base extract comprising hop oils and lupulones is precipitated, mixing the lupulones with adsorbents, converting the lupulones to bitter-tasting hulupones by oxidation and treatment with CO2 under pressure, and removing undesirably accompanying substances to purify the thus obtained hulupones. Hulupones obtained by the process, optionally in combination with isohumulones provide a beer-soluble product which, as a bitter constituent, has all the taste properties of natural hops.

Patent GB-2079167-A (GB)
Title: Gasifying a liquid
IPC: B01F3/04
Filed: 1980-06-26
Abstract: Liquid to be gasified is passed, in the presence of the gas, down a surface of a sufficient length in the direction of flow to cause the flowing liquid to achieve a terminal i.e. saturated, condition in which there is no further change in its velocity or in its thickness as measured normal to the surface; the surface being such that turbulence is induced in the flowing liquid at least when it achieves the terminal condition. Liquid gasified in one run down the surface may be further gasified by a second or subsequent run; and the total time the feedstock is maintained in its terminal condition will depend on the amount of gasification to be effected; the maximum time being that at which the liquid is incapable of taking up more gas. The invention is particularly useful for aerating sewage sludge. <IMAGE>

Title: Peat blocks
IPC: A01G9/10
Filed: 1980-10-17
Abstract: Compressed growth substrate blocks which swell when moistened are prepared from predried peat (moisture content less than 35%) by compressing the same to a thickness of at least 1/3 of its thickness after drying, a higher degree of compression being used on the border areas of the peat blocks than on other areas. Thereby the peat fibres in the more compressed border areas orient themselves partly in the direction of pressure and are bonded together by the natural resinous substances in the peat under the influence of the higher compression forces, thus imparting good cohesive characteristics to the block also when moistened. Advantageously also a small indentation for a seed is simultaneously pressed into the growth substrate block. A pressing device for use in the above method comprises a press-plate and a moulding tool for pressing thereagainst the moulding tool being provided with substantially blunt-edged ridges projecting therefrom in the direction of compression for imparting the higher degree of compression on the border areas of the growth substrate block.
