Filed: 1974-02-06
Abstract: 1465942 Vehicle safety devices INVENTING AB 6 Feb 1974 [12 Feb 1973] 05441/74 Heading B7B [Also in Division F2] A method of manufacturing a tubular enelosure for storing or transporting fluids or fluidized solid particles under pressure which may be used as a collision shield for vehicles comprises forming a readily expandible inner tube by joining the edges of a sheet or sheets of thin flexible stretchable fluid impermeable material so that it is expandable from a normally flat cross-section to a tubular cross-section, and forming a normally flat outer covering by joining the edges of a sheet or sheets of material less flexible than that of the inner tube, so that the outer cover limits the degree of expansion of the inner tube upon expansion thereof. The outer wall may consist of an upper part 6 and a lower part 7 of strong flexible material, e.g. a woven fabric of nylon or glass fibres or other synthetic or natural fibre material seamed as at 8 with rivets or by screwing or welding or may be of a single strip of material folded over. The inner wall can also be formed of separate strips of material seamed along contacting edges, or of a single strip folded over and is preferably formed of a thermoplastics material, e.g. a polyolefine, p.v.c., or a so called plastics rubber or a mixture of polythene and ethylene-vinylacetate or polythene and plastics rubber or of polyurethane. The inner wall can also incorporate pleats 9 to aid in the expansion thereof. The inner wall and outer wall can be free to move relative to each other or can be joined pointwise or zonewise. Various other forms of tube constructions are disclosed in Figs. 7 to 14 and 21 (not shown) and the invention can also be applied to form branch tubes (Figs. 2, 3 or 4, not shown).

Patent GB-491087-A (GB)
Title: Machine for assembling slips or sheets in overlapping or spaced relationship
IPC: B65H5/24
Filed: 1937-02-25
Abstract: 491,087. Making manifold books. SHAW & SONS, Ltd., FOX, F. E. T., and MARTIN, F. R. Feb. 25, 1937, No. 5705. [Class 16] [Also in Group XVI] A machine for assembling slips in overlapping or spaced relationship, which is especially applicable for making a block containing a number of receipt slips for rate collectors, comprises in combination an oscillating pneumatic carrier 41 which lifts the slips one at a time from a supply table 3 and carries them to a movable table 10 arranged at a slightly lower level than the table 3 and adapted to be moved to the left to a slight extent between each operation of the pneumatic carrier so as to cause the slips to be deposited in overlapped formation on a backing sheet 2 carried by the table 10. The sheet 2 is registered against a side lay 10<1>, and is supplied with lines of paste 64 to cause the slips to adhere to the backing. The slips are supplied by hand from a stack 6 and are advanced by a reciprocating pusher 7, fitted with adjustable side gauges, to the table 3. The pneumatic carrier 41 is pivotally mounted in oscillating arms 44 and is controlled by a rod 53 passing through a pivoted guide 54 so that its apertured face is parallel to the surfaces of the tables 3, 10 when engaging slips thereon. The table 10 is at a lower level than the table 3, and the table 10 is attached to a counterweighted chain, which is advanced intermittently by a sprocket operated by a ratchet 15 and a pawl 19 on an arm 20 operated by adjustable crank mechanism. A pawl 35 engaging teeth 36 on a fixed rack prevents return of the table 10, the advance of which at each operation is equal to the distance between the teeth 36. When the required number of slips have been assembled the pawl 35 is released and the table 10 returns under action of a weight 32. The underside of the carrier is fitted with pads coinciding in position with the lines of paste 64, and the pads press the edges of the slips into contact with the paste. The motion of the pusher 7 is derived from the shaft 45 which operates the carrier 41, and the whole machine is driven by a onerevolution clutch controlled by a pedal 66.

Filed: 1974-02-07
Abstract: 1455774 A spectrophotometer using an electromagnetically activated oscillating chopper PYE Ltd 7 Feb 1974 05738/74 Heading G1A In a spectrometer, Fig. 1 different parts 30A, 30B, Fig. 2 of a beam 30 are alternately allowed to travel along different respective paths 10, 12 by means of a flag 31 oscillating in the direction 34 and which is attached to a rod 36 slidable telescopically in a stainless steel tube 40. The tube 40 is fixed to a soft iron armature 44 mounted on a spring steel strip 48 clamped in split rods (50, 52), Fig. 3 (not shown), to ensure torsional oscillation. The armature 44 is in the magnetic circuit 60, 62 of an electromagnet 64 supplied by an an A.C. source 28 which also supplies a pulse shaping and timing circuit 24 of a demodulator 22 connected to the amplified output of a detector 18. The reasonant frequency of the modulating system can be adjusted by means of an adjustable polythene weight 38 to ensure that the reasonant frequency is not "near" the oscillating (A.C.) frequency of the source 28. As can be seen radiation from a source alternately passes via a sample cell 14 and a reference cell 16 to be received by the detector 18 whose output is demodulated in a fixed phase relationship with the A.C. oscillations from the A.C. source 28 and the two voltage signals Vr, Vs representing the sample and reference beams are fed to a circuit 26 which produces a signal equal to log (Vr/Vs).

Title: Improvements relating to traction wheels for use with endless tracks
IPC: B62D55/10
Filed: 1920-02-26
Abstract: 161,789. Paulsen, T. R. Feb. 26 ,1920. Endless-track vehicles. - Wheels for tractors, of the type in which an endless track passes round a driving- wheel and two guide-wheels, are designed to yield to irregularities in the ground surface, without lifting the tractor as a whole. For this purpose the guide-wheel axles can swing independently about the central axle 19 by means of radius rods 9, and the consequent variation in the distance between the guidewheel axles is allowed for by the sliding connection 3 between one axle and its pair of supporting-beams 1. Springs 25 support the central axle resiliently on the beams. Both the inner and outer rings of teeth on the driving-wheel 20 are formed in separate segments bolted together, so that a part of either gear can be removed separately for renewal without dismounting the track and the wheel as a whole. The ground-engaging spikes or studs of the endless-track are formed with a series of bosses 28 at each end, the bosses on the meeting ends of adjacent studs being arranged in staggered relation to produce a continuous boss for the reception of the connecting-pins 30. The inner bosses are formed with ribs 29 having offset overlapping ends to produce two continuous tracks on which the rims of the driving sprocket wheel ride, while the teeth project into the space between these tracks. The teeth, by bearing on the pairs of alined studs between the tracks at the same time, exert a common pressure on each pair of adjacent studs with which they contact.

A tube of plastic material is extruded through a die 37 around a member 46, Fig. 3, and the tube gripped by ring halves 58, 59. The tube and the assembly 46, 58, 59 is then moved upwardly, and mould halves 12, 13close about the tube. Compressed air is supplied through a conduit 51 to blow the tube to the shape of the mould. A knife 63 is reciprocated in guides 64 to cut the tube from the moulded article. The knife may also act to prevent further extrusion until the next operation begins. The blowing may begin before the mould closes to stiffen the tube, and continue after, to facilitate release. In a modification, the tube may be blown through the extrusion die. The mould plates 10, 11 are moved hydraulically and have ribs 10<SP>1</SP>, 11<SP>1</SP> which engage prismatic guides 8, 9, respectively. The exact positioning of the mould halves is controlled by nuts 28. Wedges 31, 32 prevent movement of the mould plate 11 until a projection 36 on the mould plate 10 operates a switch 35.

[Classes 1 (i) and 95] [Also in Groups VI, IV, V, and XXIII] The admixture of dry powderous substances. e.g. catalysts and pigments, is facilitated by treating one or more of the powders by a wet process with a lyophilic protein colloid and then with a tanning agent and mixing the dry powder coated with tanned protein with the other powderous ingredients. The protein-coated powder may be formed by precipitation from solution in presence of the protein. Water soluble substances may be coated with protein by precipitation from common aqueous solution by addition of a precipitant liquid, e.g. alcohol, the tanning being effected by a solution of an agent in an organic solvent, e.g. zirconium oxychloride in alcohol. Various water soluble proteins are suitable and are employed in amounts of 0.05 to 2 per cent. of the solid to which they are added. Various tanning agents are suitable, i.e. heavy metal salts, tannins, syntans, urea, cyanamide, picric acid, quinone, aldehyde. An example refers to the mixture of iron oxide with talc and calcimine wall paint. Specification 523,736 is referred to.
