Title: Method for producing a liquid resin
IPC: C08G16/02
Filed: 1976-11-23
Abstract: 1529906 Liquid furan-formaldehyde resins QUAKER OATS CO 23 Nov 1976 [2 Jan 1976] 48837/76 Heading C3R A method of producing a liquid resin comprises reacting 1 mole of formaldehyde with at least 1À1 mole of a furan of the formula:- wherein R and R<SP>1</SP> are hydrogen, halogen, alkyl, phenyl, alkyl or halogen substituted phenyl, carboxy, hydroxy-alkyl or carboxyalkyl and in which the alkyl substituents have from 1 to 10 carbon atoms in the presence of a catalytically effective amount of an acid catalyst, for a period of time sufficient to produce a liquid resin, e.g. a resin having a viscosity of less than 25,000 c.p.s. at 30 C. Suitable catalysts are acids having a pKa of less than 3À0 at 30 C., e.g. sulphuric, hydrochloric, phosphoric, oxalic, malonic, methyl sulphonic, trichloroacetic and benzoic acids. The reaction may be carried out at temperatures above 30 C., pressures above atmospheric and under aqueous conditions, e.g. when 37% aqueous formaldehyde is used or under non-aqueous conditions, e.g. when paraformaldehyde is used as the source of formaldehyde. The examples, in which furan itself is reacted with formaldehyde, illustrate the reaction conditions, e.g. the combination of time, temperature, mole ratio of reactants, catalyst type and concentration, which are required to produce liquid resins of predetermined viscosity and reactivity, i.e. the rate at which the resin is cured by an amine-hydrochloride/furfural/ water catalyst mixture. Resins obtained under reaction conditions that allow complete conversion of the formaldehyde used have lower reactivities than resins obtained under conditions that allow lower, e.g. 40% formaldehyde conversions. Use:- the liquid resins may be used as binders in the production of foundry cores and sand moulds.

Title: Drying fabrics treated with chlorinated hydrocarbons
IPC: D06B9/06
Filed: 1971-10-21
Abstract: 1362676 Dry cleaning BRUCKNER-APPARATEBAU GmbH 21 Oct 1971 [21 Oct 1970] 48875/71 Heading D1A [Also in Division F4]  Textile fabrics which have been dyed, bleached or cleaned using a chlorinated hydrocarbon solvent (e.g. perchlorethylene) are initially dried with hot air and then brought into contact with water vapour to form an azeotropic mixture of solvent or water which is removed by drying with further hot air. The small amount of water condensing from the vapour onto the fabric forms the azeotropic mixture with residual solvent remaining after the initial drying, the azeotropic mixture boiling below 100‹C. The fabric is initially dried until the moisture content produced by the subsequent treatment with water vapour does not appreciably exceed the normal moisture content of the fabric. In an example, fabric is dyed, spin-dried, and then initially dried with hot air with the temperature being increased from 20‹ to 80‹C.

Title: Body attached flying device
IPC: B64C39/02
Filed: 1964-12-11
Abstract: 1,093,720. Aircraft fitted to the person. E. UHOR. Dec. 11, 1964, No. 50516/64. Headings B7G and B7W. An aircraft for direct attachment to the body of a pilot comprises a forward housing section 14 for removably receiving the upper portion of the pilot, a rear tail leg supporting section 16 connected by a hinge pin 38 to the housing section 14, a pair of foldable wings 70 mounted on the housing section 14, and control surfaces on the wings and tail operable by an axially and rotatably movable control stick 86 and by footoperated levers. The aircraft is powered by propellers mounted on the wings and when not required for use it can be folded and carried on the pilot's back. To fold the aircraft latches 52 are released and the tail section 16 is folded up to the pilot's chest and an undercarriage 254 locked to a chest plate 30 is pivoted to a position overlying the shoulders of the pilot, Fig. 5 (not shown). Each wing 70 is mounted on a shaft 68 rotatable in a cross-bore provided in a shaft 64 capable of being rotated by bevel gears 111. If the wings are to be moved to their folded position a lever 116 is operated whereby the bevel gears 111 on the ends of the shafts 64 are rotated through gears 114, 115 and a coupling shaft 112. To enable the folding operation to be performed the shafts 64 are provided with jaw clutches 317 arranged to be engaged by a cam mechanism, Fig. 17 (not shown), automatically operated by rotation of shafts 64. The cam mechanism is also arranged to disengage bevel gears 120, 128 from engagement with bevel gears 117 freely rotatable on the shafts 64 and in constant mesh with the gears 110 fixed to the wing shafts 68. The clutches are arranged to be engaged one after the other so that the shaft 68 of one wing is first rotated about its own axis whereby one wing overlies the other when folded. The shafts 68 are also rotatable in order to change the inclination of the wings for horizontal or vertical flight. A lever 121 is provided for this purpose, the lever operating through bevel gearing 120, 117, 118, a transverse shaft 119 and further bevel gearing 128, 117, 110. A spur gear mounted on the transverse shaft 119 is arranged to cause simultaneous movement of a rack along a slide 130, the rack causing pivoting of the tail section through gear and cable linkage. A mechanism for causing locking of the rack or movement thereof in the opposite direction for reverse pivoting of the tail with respect to the wings is provided. Thus operation of the lever 121 is capable of simultaneously pivoting, in the same or opposite direction, the wings and tail section for enabling vertical and horizontal take-off, landing and flight. The tail section 16 comprises a pair of tail members 192 (one for each leg of the pilot), from each of which extends at right-angles thereto a foot-operated rudder. Each tail member has a large wheel 246 for use during conventional take-off and landing and a smaller wheel 242 for assisting during vertical take-off or landing.

Abstract: 1369345 Sound absorbing structure for jet engines LOCKHEED AIRCRAFT CORP 7 Nov 1972 [8 Nov 1971] 51333/72 Heading F1J [Also in Division F2] A sound absorbing structure particularly useful for installation in the housing or pod enclosing an aircraft jet engine comprises a honeycomblike cellular layer, an impermeable backing closing one end of the cells, and oblique permeable partitions having a specified flow resistance in each cell. It is the open ends of the cells which face the noise source and each cell is of a diameter less than half a wave length of the sound, with the result that the sound is projected along the acoustic wave guides formed by the cells only in planar wave form. The permeable partitions have an optimum flow resistance of 330 Rayls and may comprise a sheet of felted metal fibres. In one embodiment, as shown in Fig.10, a plurality of ring-shaped and spacedapart parallel walls 42, 43, 48 extend upwardly from a solid backing member 41 and divide the structure into adjacent cellular compartments. Each compartment contains a diagonal oblique permeable partition 44, 47. A perforate facing member 45 is provided. Another embodiment of similar application, shown in Fig.16, comprises a solid backing member 67 in the form of a cylindrical duct or conduit, the interior surface of which supports compartment-defining permeable partitions 65, 66 welded together at their upper and lower ends 64, 68.

Title: Method and apparatus for crimping yarn
IPC: D02G1/12

Abstract: In a stuffer-box crimping apparatus such as described in the parent Specification, a weighted, pivoted finger presses against the side of the core of crimped yarn at a point in the crimping chamber in advance of the core-discharge position.  The finger exerts a continuous, controlled, retarding pressure on the core thereby controlling the back pressure on the core in advance of the finger. A sensing member, resting lightly (i.e. without adding to the back pressure) on the core at the discharge point, initiates regulation of the relative rates of feed and withdrawal of yarn so as to maintain the discharge point at a constant level.
