Title: Agglomeration of water soluble instant foodstuff powder
IPC: A23L19/00
Filed: 1972-12-20
Abstract: 1399650 Agglomerated food powders; instant coffee preparations D E J INTERNATIONAL RESEARCH CO NV 20 Dec 1972 [20 Dec 1971 30 June 1972] 58713/72 Headings A2B and A2E An instant agglomerated foodstuff comprises primary particles connected by solid "bridges" in which are embedded aroma and/or flavour enriched droplets of an edible oil, and is made by homogenously distributing the oil through the foodstuff while the primary particles are being fused together to form the agglomerates. As an example, instant coffee is prepared by agglomerating particles of spray dried coffee extract using an emulsion of water and coffee oil in which has been dissolved aromatic and/ or flavouring substances previously extracted from the coffee. The aromatic and/or flavouring substances can be extracted from the coffee by steam distillation or by solvents such as liquid CO 2  or fluorine compounds, and dissolved in the oil while the remainder of the coffee is made into a spray dried extract. The aromatic and/or flavouring substances are dissolved in the oil which is emulsified with an aqueous 20-30% coffee solution. The emulsion is then used to agglomerate the spray dried particles, which are then dried by fluidised bed or vacuum. A coffee substitute such as chicory may be incorporated.

Patent GB-1341830-A (GB)
Title: Signalling device for coupling across a transmission line
IPC: G08B25/08
Filed: 1970-12-31
Abstract: 1341830 Time signalling system; oscillator circuits H B ENG CORP 31 Dec 1970 [31 Dec 1969] 61992/70 Headings H4J H4R and H3T [Also in Division G4] In a signalling system having a plurality of controlled current circuits connected to a single transmission line, the output impedance of the circuits is made at least 10 times greater than the characteristic impedance of the line. It is suggested that mutual interference by a plurality of remote stations and effects due to   noise are substantially eliminated by this deliberate mismatching of the individual circuits to line. The signalling may be effected in respect of fire, burglary, smoke, movement, pressure or optical conditions sensed at a station. The line may be a power line or form part of a CATV distribution network. Each station utilizes an individual frequency for modulating its current circuit so that the individual signals can be picked off by narrow band filters at a central station. Each station comprises a current controlled source in the form of two series connected transistors 40, 42 having a large value emitter resistor 43 to provide negative feedback and to limit the current through the transistors so that their high output impedance is substantially constant. Modulation is effected by an oscillator consisting of transistors 52, 53 and a mechanical resonance device 60 called a twintron. The latter consists of a H-shaped resonator having piezoelectric input and output transducers attached to a flexible cross arm between two massive side arms of the H. Further details of its mode of operation may be derived from Specification 1,198,326. Diodes 64, 65, limit the oscillator voltage when this is in operation. Bias for the arrangement is provided by transistor 48 and Zener diodes 45, 50 which are fed by D.C. over the transmission line 11, 12. Normally all transistors are conductive and draw a very small quiescent current from the line. In response to opening of sensor switch 68, e.g. by melting of a heat responsive element or actuation of a microphone, the oscillator turns-on so as to linearly modulate the quiescent current. A simplified arrangement which dispenses with transistors 48 and 40 and utilizes a local bias source is depicted in Fig. 4 not shown.

Title: Improvements in or relating to a process for the purification of gaseous mixtures
IPC: B01J20/16
Filed: 1969-12-24
Abstract: 1275140 Separating NO from N 2 O L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 24 Dec 1969 [27 Dec 1968] 62950/69 Heading B1L [Also in Division Cl] NO contained as impurity in gas streams comprising predominantly N 2 O is removed by contacting the gas stream under non-oxidising conditions and generally at ambient temperature with a molecular sieve, suitably a mordenite charged with an elemental transition metal, e.g. Cu, Co, Ni or, preferably Fe. Thus, a gas stream from the thermal decomposition of NH 4 NO 3  and containing NO, NO 2 , N 2 O 4 , NH 3  and H 2 O in addition to N 2 O is suitably first washed with water and/or NaOH solution and then passed through a guard bed of a zeolite, such as an acid mordenite, before entering the metal-charged bed where residual NO is removed. The beds are regenerated by vacuum or by elution with a reducing and/or inert non-oxidising gas, and if desired at elevated temperature. Periodically, any decrease in bed activity resulting from metal oxidation may be overcome by a reduction step. A twocolumn dual-bed process is described in which one column is on stream while the other is being regenerated (see Fig. 2, not shown).

Title: Gas Cleaning
IPC: B03C3/013
Filed: 1979-03-30
Abstract: In the removal of dust from a sulphur dioxide-containing dust-laden gas stream the gas stream is conditioned by converting sulphur dioxide into sulphur trioxide by the action of a plasma; and the gas, containing the resulting sulphur trioxide, is passed through an electro- precipitator 12. The plasma may be produced in a plasma generator 14 by subjecting nitrogen to electric discharge to produce active atoms, which form sulphur trioxide through the intermediate step of forming active oxygen by reaction with nitric oxide in the gas to be cleaned; or an oxygen plasma may be used. The sulphur dioxide content of the gas may be further reduced by introducing additional plasma downstream of the electro- precipitator 12 and removing the resultant sulphur trioxide in an acid mist electro-precipitator; in a modification of this process, the first electro-precipitator 12 is replaced by a bag filter. A portion of the gas may be recycled from downstream to upstream of precipitator 12. The plasma generator includes an arc rotated by a polyphase A.C. field, thereby spinning and mixing the plasma. <IMAGE>
