Filed: 1960-08-26
Abstract: 974,999. Fog dispersal. A. E. RICHARDS. Aug. 21, 1961 [Aug. 26, 1960], No. 29474/60. Heading A1X. In apparatus for dispersing fog or snow over runways hot exhaust gases from gas turbines1 together with cold air drawn in through fans 3 is fed into ducts 4 extending round the runway and having exit nozzles 7 the direction of which can be varied, the hot gas emerging from the nozzles 7 causing the air over the runway to rise upwardly. The gas in the ducts 4 is diverted to the nozzles 7 by adjustable deflection plates 10 and by means of further deflection plates 13 is fed into a duct lying along the centre of the runway and having outlet nozzles 9 flush with the runway. Gas remaining in the centre duct passes to one of the fan intakes 3 through valve 12. The fans 3 are powered from generators 16 driven through gearing 15 by impellers 17 in the path of the gases from the turbines.

Title: Improvements in and relating to the construction in situ of reinforced concrete floors and the like
IPC: E04G11/46
Filed: 1932-10-21
Abstract: 406,411. Concrete floors and roofs; casting in situ. CULLUM & CO., Ltd., H. W., 50, Britannia Street, Kings Cross, and MOURITZ, C., Grove End House, St. John's Wood, both in London. Oct. 21, 1932, No. 29482. [Classes 20 (ii) and 20 (iv).] Reinforced-concrete floors, roofs, and the like are formed by first casting a lightweight core 3 entirely in situ in such a way as to form channels, and then filling the channels and covering the core with the main concrete body 4. The core 3 is cast upon a temporary centering 1, on which trough-shaped forms 2 to mould the channels are supported. If desired, the forms 2 may be mounted on spaced blocks or provided with integral studs to space the forms above the centering, whereby the core 3 may be cast beneath the forms 2. The forms 2 may be left in position, and the concrete 4 is then cast inside the forms. Alternatively, the forms 2 may be solid. The centering 1 may be provided with a thin skin of concrete or a lining 6 of waterproof paper prior to casting the core 3. Reinforcements 5 are provided in the channels in the core 3. The core material may comprise cellular concrete, or a compound, such as calcium anhydrite, which rises and assumes an arched shape between the channels. In addition to the parallel forms 2, other forms may be arranged at various angles to such forms to present a reticulated configuration.

Title: Nitration process of toluene
Filed: 1946-10-04
Abstract: Tri-nitrotoluene is prepared by a process in which toluene is nitrated continuously in at least three steps by mixed acid containing at least 30 per cent free SO3, fresh acid being used in the last step and the spent acid from each step being used in the preceding step with the addition of fresh moderately concentrated, 60 per cent nitric acid.  The nitrated product from each step is separated from the spent acid and treated in the next step with the stronger acid of that step.  Preferably, three nitration steps are used and the conditions are adjusted so that the product from the first step is predominantly mono-nitrotoluene, that of the second is a mixture of mono- and di-nitrotoluene and that of the third tri-nitrotoluene.  The fresh acid supplied at the last step should contain at least 30 per cent of free SO3 and at least 30 per cent of nitric acid and the supply is adjusted so that the spent acid contains only a few per cent of free SO3 or at most 8 per cent of water. Part of this spent acid may then be introduced into the second and another part into the first step of the process after adjustment of the nitric acid content and the residuum may be utilized if desired in the Glover tower of a sulphuric acid plant.  The tri-nitrotoluene is separated in the final stage by cooling and crystallisation.  A preferred embodiment of the invention is illustrated with reference to drawings.

Title: Improvements in or relating to electrical switching equipment employing crystal triodes
Inventor: ODELL ALEXANDER DOUGLAS

Filed: 1953-10-28
Abstract: 794,656. Digital electric calculating apparatus. STANDARD TELEPHONES & CABLES, Ltd. Oct. 22, 1954 [Oct. 28, 1953], No. 29848/53. Class 106 (1). [Also in Group XL (c)] In a half-adder, transistor switches are used in which the base potential exceeds the common D.C. potential of the emitter and base to present a high impedance between emitter and base, the switch being operated by lowering the base potential (see Group XL (c)). O and I pulses of the augend in binary code are applied to a trigger circuit a1 so that the former cause switch A to operate and the latter switch B. In a similar manner, O and I pulses of the addend cause trigger circuit a2 to operate switches C and E or D and F respectively. If an " I " occurs in the augend, switch'B operates and a master pulse passes to switches E and F. Assuming there is an " I " in the addend switches D and F will be operated so that the master pulse passes through switch F and diode MR7 to transformer T8 to indicate " 0 ". The pulse also passes through diode MR8 and delay line d1 to the transformer T9 to add to the " 1 " input. Assuming the second digit is an " 0 " for the augend and addend, the " 1 " carried forward keeps switches D and F open, while the " 0 " of the augend operates switch A so that the next master pulse passes through switch D and diode MR9 to register a " 1 ". The pulse is also fed through diode MR10 and delay line d2 and transformer T10 to switch the trigger circuit to the " 0 " condition with switches C and E operating. If the third digit of the augend is an" I," switch B is operated and the master pulse passes through switch E to register an " I " and through delay line d2 and transformer T10 to retain the trigger circuit in the " 0 " condition.

Title: Manufacture of halogen-substituted alcohols
IPC: C07C31/34
Filed: 1935-11-02
Abstract: Halogen-substituted alcohols are prepared by reaction of hydrogen chloride or bromide and formaldehyde or a substance yielding formaldehyde on a compound having at least one olefinic double bond in an open chain or alicyclic ring and containing no alcoholic hydroxy group.  In place of hydrogen halide and formaldehyde, products of their mutual reaction, such as dichlordimethyl ether and dichlormethylal, may be employed in presence of water.  The olefinic compounds may be represented R1R2C = CR3R4 where R1R2R3R4 stand for hydrogen or any substituents other than alcoholic hydroxy groups, e.g. alkyl, alkylene, halogen, alkoxy, aryl, aralkyl, hydroaryl, --CO--alkyl, aroyl, --COOH, --COOR5 (R5 being alkyl or aryl) or a heterocyclic residue, or R1 + R2 stands for oxygen. The two carbon atoms may also be members of an alicyclic, iso- or hetero-cyclic ring.  Catalysts such as halides of group 2 metals, or of iron may be present.  Pressures up to 200 atm. and temperatures of 100--200 DEG C. may be employed.  Starting materials specified are butadiene, cyclohexene, ketene, vinyl-methyl ether, and crotonic acid.  In examples: (1) propene is forced at 50 DEG  C. into a 30 per cent formaldehyde solution saturated with HCl.  The product is steam distilled to yield g -chlorbutanol; (2) the same product is obtained by passing propene and HCl over paraformaldehyde at 50 DEG  C., or into a suspension of paraformaldehyde in CCl4; (3) formaldehyde solution containing ZnCl2 is saturated with HCl, and ethylene forced in at 60--70 atm. yielding 3-chlorpropanol-1; (4) in a tube containing formaldehyde solution saturated with HCl and mixed with CaCl2, vinyl chloride is condensed by cooling.  The tube is sealed and heated to 50 DEG  C. to obtain 3.3-dichlorpropanol-1 and the b -dichlorhydrin.  In a similar manner isobutene gives an alcohol which is probably <FORM:0465467/IV/1>
