Patent GB-608109-A (GB)
Title: Improvements in or relating to adhesives
IPC: C09J161/20
Filed: 1946-02-15
Abstract: An adhesive comprises an amido-formaldehyde condensation product (e.g. a urea-, thiourea, and/or melamine-formaldehyde condensation product) and 2 to 50 per cent (preferably 5 to 25 per cent) of its weight of di-(tetrahydrofurylethyl) carbinol and, if desired, water and mixtures of wood flour and finely-ground minerals such as china clay.  In the preparation of the condensation products, 1 mol. urea (which may be partly or wholly replaced by other compounds containing a plurality of -NH2 groups forming part of amide, thioamide, and/or amidine groups, e.g. thiourea or melamine) may be refluxed in the neutral condition with 2 mols. of aqueous formaldehyde, reducing the water content by distillation under reduced pressure and, if desired, spray-drying.  When 1 mol. of melamine is used, 3 mols. of formaldehyde may be employed.  When preparing the adhesive from dried condensation products, 10 to 50 per cent (by weight of product) of water may be added.  0.1 to 2.0 per cent (by weight of condensation product) of ammonium chloride may be used as hardener.  In an example, 1 mol. of a mixture of urea and melamine in the molecular ratio of 20 to 1 was refluxed in the neutral condition with 2.2 mols. of aqueous formaldehyde for 3 hours and the syrup was dehydrated to a solids content of 72 per cent.  An adhesive was prepared by mixing (parts by weight) 80 parts syrup, 12 parts water, 20 parts china clay, 10 parts wood flour, 1 part ammonium chloride and 10 parts di-(tetrahydrofurylethyl) carbinol. Specification 476,189 is referred to.

Title: Improvements in making moving pictures
IPC: G03B15/12
Filed: 1924-02-25
Abstract: 234,542. Withers, J. S., (Akt.-Ges. f³r Spiegeltechnik). Feb. 25,1924. Composite photographs; studio accessories.-A method of producing kinematograph films consists in erecting in natural size only a portion of the object, e.g. that in front of which characters move, and in employing for the remainder models of reduced size, photographs, projected background diapositives or kinematograph pictures, the parts being photographed simultaneously or successively, the object by reflection, and the model &c. either directly or by reflection, at suitably shaped or masked mirrors. In the form shown in Fig. 2, 4 represents the portion of the object erected in natural size and this is reproduced in the camera 5 by reflection in a mirror 7 whose reflecting outline corresponds exactly to that of the object 4. Between the object 4 and the mirror may be employed an apertured screen 10, having its rear surface coloured or shaded, to suppress disturbing reflections. Behind the mirror 7 is a reduced model 9 of the remainder of the object. The model 9 and the screen 10, or a glass plate between the mirror 7 and camera 5, may be employed to support auxiliary mirrors, such as 16, the object of which is to reflect to the camera reproductions in natural size of other portions of the object, such as 17, at which minor actions occur. By such means, minor actions which are to be depicted at a different level from the main action 4 may be performed on the same level if the auxiliary mirrors are suitably inclined. The mirror 7 may be semitransparent and rendered opaque at the parts corresponding to the object 4 by opaque paper applied on its back. In place of the model 9 a picture, photograph or an illuminated diapositive of the model may be employed, or a diapositive or kinematograph film may be projected from the rear upon a semi-transparent screen placed behind the mirror 7. To obtain pictures with the parts correctly exposed, the main action performed at 4 and the projected model are exposed separately on the same camera film, suitable masking-devices being employed. In the event that a character, performing at 4, should step beyond the outline of the portion of the scene erected at 4, this scene is surrounded by a black background and a mirror balanced by weights is supported above the mirror 7 so that it may be lowered in front thereof, its size corresponding to the full size of the picture. The section of the film in which such an event occurs must be combined with a section of equal length depicting the supplemental object 9 to produce a composite picture. The outlines of the various reflecting surfaces and the screen apertures are determined and adjusted by projecting thereon, from the camera or from a projector used in its place, a diapositive of the complete scene, upon which the separating lines are marked. These lines are preferably made rough or irregular to secure better blending in the composite picture.

Abstract: 1459496 Injection moulding foamed plastics EX-CELL-O CORP 4 Feb 1974 4997/74 Heading B5A Means for foaming and moulding a plastics material comprises a pressure tight supply hopper 26 into which granular plastics material and a gas under pressure are introduced, the hopper 26 being connected in pressure tight manner to a plasticizing chamber 17 wherein the material is converted to a plasticized foamed material with the gas entrained therein as bubbles. A plasticizing screw 18 delivers the material at low pressure through outlets 36, 37 and a distribution network 41-49, Fig. 3, to a plurality of injection assemblies as 54, 54A, 54B, 54C. Each injection assembly comprises an injection chamber 63, Fig. 4, which is connected through a discharge orifice 82, passage 83, Fig. 6, and injection nozzle 88 to a mould (13, 15), Fig. 1 (not shown). A check valve 52 prevents return flow to the plasticizing chamber. As the chamber 63 fills up, an injection ram 71 therein is pushed upwardly until it actuates a switch 78 whereby a valve V B  is opened and pressure fluid supplied to a cylinder 74. Since at this point an injection valve 56 is closed, downward movement of ram 71 will close a check valve 52 and prevent further filling of chamber 63. Other injection chambers are filled to a level depending on the setting of the corresponding switch 78. When all the injection units in use have been filled the valves 56 are automatically opened and injection is effected. A single injection unit may be associated with a single mould M, Fig. 3, or two injection units with a single mould M1. Alternatively a single mould M2 with either single or multiple cavities may be associated with all four injection units of a single injection assembly 54C. A still larger mould may be associated with two or more (even all eight) of the injection assemblies shown in, Fig. 3. An opening 28, Fig. 2, is provided for introducing gas under pressure into the hopper 26 and the same or an additional opening 29 may be used for evacuating the hopper. Granular plastics material may be supplied from an upper hopper 30 by opening a valve 31. The mould halves are held together by sprue in opposed recesses 92, 93, Fig. 7, in the mould halves, the sprue being supplied at the same time as the mould cavity or separately from a different source.

Title: Pure fluid amplifier
IPC: F15C1/10
Filed: 1966-02-07
Abstract: 1,140,192. Pure fluid amplifiers. CORNING GLASS WORKS. Feb.7, 1966 [Feb. 16, 1965], No. 5286/66. Heading G3H. A pure fluid amplifier which may be used as a timer comprises a bi-stable amplifier 10 having an input power jet 11, outputs 16, 18 and control signal inputs 20, 22. The control signals are applied after predetermined time intervals to switch the jet from one outlet to the other by valves 24, 26. The valve 24 comprises a two stage valve having chambers 28, 30 and 34, 36 each separated by diaphragms 32, 38 and the chamber 30, 34 separated by a wall with an orifice 40. Chambers 30, 36 have ports 44, 46 open to the atmosphere, chamber 28 is connected to a passage 50 leading from outlet pipe 84 and chamber 34 is also connected to passage 50 through a needle valve 54. In operation, assuming that the jet 11 locks on to the outlet 16, an output signal passes to passages 48, 84. Part of the outlet signal flows through pipe 50 to chamber 28 and a small flow passes through the valve 54 to chamber 34. The fluid in chamber 34 flows through orifice 40 and outlet 44 of chamber 30 until the pressure in chamber 28 is sufficient to cause diaphragm 32 to seat on orifice 40. The restricted flow through valve 54 to chamber 34 causes a build up in pressure until the diaphragm 38 closes the end of passage 42 leading to the control nozzle 22. The flow of the main jet to outlet 16 which has previously entrained fluid through port 46, chamber 36 and passage 42 now causes a pressure gradient across the jet to switch it to outlet 76. The pressure in passage 50 is now released and the valve 24 reset while the flow in 76, 86 acts on valve 26. Thus the jet 11 is switched between the outlets after a time interval determined by the needle valves 54, 82 in conjunction with valves 24, 26.
