Abstract: 1,265,395. Expanding cases. H. G. DYKE. 15 April, 1969, No. 19255/69. Heading B8P. [Also in Division E2] A case, which may have lid and body portions made of moulded plastics shells, has a joint formed of an elastomeric strip around the entire case which enables the case to expand. The strip 55 is shown unexpanded in Fig. 13 and expanded in Fig. 14, both figures showing the invention applied to a dispatch case. Studs 48 engage cavities 49 when the strip is not expanded. A strip 65 with stiffening ribs 68 is fixed across the inside of the joint to prevent any tendency for the case to sag as the joint expands. A liner cover 70 is provided to ensure a smooth interior surface. There may be a second joint in the other part of the case.

The invention comprises unsaturated nitro compounds of the formula (wherein R and R<SP>1</SP> each denote H atoms, C 1-15  alkyl groups or C 5-12  aryl or cycloalkyl groups) and a process for their preparation and of similar compounds by reacting a conjugated diene CH 2  : CR 1 .CR 2  : CHR 3  with an organic nitro compound (R)(R<SP>1</SP>)CH.NO 2  (wherein R and R<SP>1</SP> denote H atoms, C 1-15 aliphatic groups, C 5-12  alicyclic groups, or C 6-15 aryl groups; R 1 , R 2  and R 3  each denote H or halogen atoms, or alkyl groups) to yield an unsaturated long-chain nitro compound having at least one octadienyl residue attached to the carbon of the nitro reactant via the 1- or 2-position. The process is effected with a palladium or platinum catalyst preferably in the presence of more than a molar equivalent amount (of catalyst) of a trivalent phosphorus, arsenic, or antimony compound, particularly hydrocarbon derivatives of PH 3 , AsH 3  and SbH 3 . Specified dienes include 1,3- butadiene, isoprene, chloroprene, 2-ethyl-1,3 butadiene, and 2,3-dimethylbutadiene, and suitable catalysts are salts or complexes of Pd or Pt, many being specified, which are preferably used in the presence of a base or reducing agent, and a stabilizer. The resulting nitro compounds may be reduced to the corresponding amines by hydrogenation or with conventional chemical reagents. The process is illustrated by 142 examples and Examples 74-89 also illustrate the subsequent reduction to amines, including 1-octylcyclohexylamine, nonylamine and the following nonylamines: 1-ethyl, 1,1-dimethyl, 1-methyl, 1-methyl-l-octyl, 1.ethyl.1.octyl, 1,1- dioctyl, 1-( 1-ethylhexyl), 1-ethyl-3,8-dimethyl; and 3,8-nonadienylamines: 1-ethyl, 1,1-dimethyl, 1-methyl, 1-ethyl-1-(2,7-octadienyl), and 1,1.di.(2,7-octadienyl).

Abstract: 1296486 Cooling granular material NATIONAL ENG CO OF CANADA Ltd 7 April 1970 [10 April 1969] 16489/70 Heading F4U Hot foundry sand is passed through a chamber in which it is cooled by a supply of water which is automatically controlled according to the electrical resistance of the sand in the chamber. The resistance depends on the moisture content of the sand and therefore, approximately, on the temperature of the sand. As illustrated, sand passes from a conveyor 12, through a chute 16, into the chamber 20, The sand is moved through the chamber to an outlet, Fig. 4 (not shown), by two rotary stirring assemblies 18 and 50 driven by a common motor 70. The current drawn by the motor is sensed and the resulting signal is used to control the position of a door at the outlet from the chamber. The motor current depends on the load on the motor and therefore on the level of sand in the chamber, and the control system is such that the door operates to maintain a constant sand level. The chamber 20 is bounded by a rubber sidewall 30 having apertures 48, formed by crossed slits, through which air is passed from a blower 46. The air aids in the cooling of the sand by the evaporation of water which is added from a header 100. The supply of water is governed by a valve 110 which is controlled by a system responsive to both the electrical resistance of the sand and the level of the sand. The resistance is measured by passing current between at least one pair of electrodes 130 mounted in the rubber wall 30. An electrode is illustrated in detail in Fig. 2 (not shown) and comprises a conducting disc hold in place on the inner surface of the wall by a bolt which passes through the wall for connection to a lead wire. The valve 110 is opened at regular intervals to admit water unless the resistance of the sand is such as to indicate that no cooling is required. The valve control system is also responsive to the motor current so that if the sand level falls below the level of the electrodes the valve is rendered inoperative.

Abstract: 1297834 Layer-multiplied filaments KANEGAFUCHI BOSEKI KK 31 July 1970 [31 July 1969] 37235/70 Heading B5B A filament is so constituted that at least part of its cross-section is formed from a layermultiplied grainy, archipelagic or nebular structure comprising polypivalolactone and a polyamide and/or polyester other than polypivalolactone. Figs. 3, 4 and 5, illustrate these forms respectively. The layer-multiplied structure may constitute the entire filament, or another polymeric material may be bonded to it in sheath-core or side-by-side arrangement as in Figs. 6-8. The filament may be non-circular as in Fig. 9. The polypivalolactone component preferably constitutes between 10 and 75% (better between 30 and 50%) by weight of the layer-multiplied structure, it may in addition be a copolymer but, in this case, the polypivalolactone must constitute at least 60%, preferably 80% at least of the copolymer. Suitable comonomers are α,α<SP>1</SP>-R 1 R 2 -#-propiolactone where R 1  and R 2  represent alkyl groups such as methyl, ethyl and propyl, or aryl groups such as phenyl. Plasticizers, pigments and stabilizers may also be added.  Exemplified polymers are nylon 6 and nylon 6,6 as polyamides and polyethylene terephthalate as the polyester. Polypivalolactone is used on its own or as a copolymer with 20% by weight of α,α<SP>1</SP>-diethyl-#-propiolactone or in a blend with 5% polyethylene. After spinning, the fibres may be stretched, at elevated temperatures around a pin before being wound up. The layer-multiplied structure is produced by use of spinnerets as disclosed in Specifications 1,192,270, 1,229,841 and 1,258,759, the joining and dividing process being carried out at least 3 times. According to the number of times this is done, and according to the composition of the extrudate, the resulting structure may have any of the forms grainy, archipelagic or nebular specified. When the filament has a form such that at least part of the surface is formed by the layermultiplied structure, the filament may be treated, either with alkali to remove part of the polypivalolactone or polyester, or with an acid to remove part of the polyamide. This treatment gives the filament a pleasant feel and lustre. When each component occupies part of the surface of the filament the antistatic properties of the filament are improved, since polyamides and polyesters generally aquire opposite charges on rubbing. The electrostatic properties may be further improved by adding a component such as polyethylene oxide which has a high conductivity.

On receipt of a pulse from oscillator 15, passing through AND gates 17 which are controlled by programme unit 18, gate 8A closes and gate 11A opens. Thus the count recorded in a fixed period is transferred to buffer store 12, 13.

This process is repeated cylically so that the output of detectors 1A-1D are read in turn and fed into memory 2. The first time an output on a given channel is read, it is fed to a given address e.g. "1" in the corresponding group A-D of locations.
