Patent GB-866563-A (GB)
Title: Production of normal butanol
Inventor: GASSON EDWARD JAMES
IPC: C07C29/00
Filed: 1959-02-07
Abstract: n-Butanol is obtained by hydrolysing n-butyl bromide by heating with water, separating the n-butanol and n-butyl ether produced, heating the separated n-butyl ether with hydrogen bromide at a temperature above 100 DEG C. and hydrolysing by heating with water the n-butyl bromide so obtained to produce further n-butanol.  The hydrolysis of n-butyl bromide may be carried out by heating with p  water at 130-180 DEG C. and a pressure of 50-200 p.s.i. Hydrobromic acid produced in the reaction may be recovered and recycled.  If the n-butyl bromide contains substantial amounts of secondary butyl bromide it is advisable to carry out the hydrolysis under an atmosphere of butene-2.  The n-butanol and n-butyl ether produced may be separated, for example, by allowing the hydrolysis product to separate into an aqueous layer containing hydrogen bromide, n-butanol and secondary butanol and an organic layer containing n-butyl ether and unhydrolysed n-butyl bromide.  The constituents of the aqueous layer may be separated by distillation.  The n-butyl bromide and n-butyl ether may be separated by distilling in a column and condensing the distillate boiling below 103 DEG C. under atmospheric pressure.  The organic layer of the distillate consisting of n-butyl bromide and water may be recycled; n-butyl ether is removed as base product.  Alternatively the whole hydrolysis product is distilled in a column to which the aqueous layer of the condensed distillate is returned and from the base of which aqueous hydrogen bromide is removed.  The organic layer of the distillate is substantially free from hydrogen bromide and is subjected to a second, similar distillation to remove n-butyl bromide as the organic layer of the distillate.  Aqueous n-butanol containing butyl ether, withdrawn from the base of the column is subjected to a further distillation to remove substantially pure n-butanol and n-butyl ether as the organic layer in the condensed distillate.  This layer may be distilled to remove the n-butanol present.  Specifications 841,745 and 843,234 are referred to.

Title: Improvements in door bell devices
IPC: E05B45/06
Filed: 1923-02-15
Abstract: 209,969. Bairstow, J. Feb. 15, 1923. Fastenings operating signalling apparatus; latches, sliding; night latches.-Electric door bell alarms are operated only when the door is opened from outside by providing independent means operable from inside and outside the door for withdrawing the main door latch, the latter means also closing an electric contact. Means may be provided to prevent withdrawal of the latch from outside except by means of a special key. As shown, Figs. 1 and 2, the outside handle 10 operates a rod 9 rotatable in a sleeve 11 and secured to a three-armed lever 12 - - 14. The inside handle 21 is secured to the sleeve 11 which is rotatable within the casing 2 and carries a lever 59. The latch 3 may therefore be withdrawn independently by either handle, but when the outer handle is turned contacts 15, 16 are closed by the part 13. A pivoted member 24 may be moved in the path of the part 14 to prevent the latch from being operated from outside. In a modification, Fig. 6, the lever operated from outside has only one arm 29 but is square at its lower end for engagement with the locking member 24. The spindle 28 is extended and carries a part 36 which presses the bent contact spring 35 on to the contact 34 when the outside handle is turned. In a further modification, Figs. 7 and 8, the latch 3 is withdrawn from inside by means of a lever 49 and pin 51. The spindle 42 rotatable from outside carries a lever 41 which passes through a hole in a bar 39 which at its end 40 engages the back of a slot in the latch 3. When the latch is withdrawn by the bar 39 contact is made between the end of the bar and a spring 45. Operation of the latch from outside may be prevented by lifting the handle 53 whereupon a shoulder on rod 52 comes in the way of a shoulder 55 on the bar 39. Fig. 10 shows an arrangement in which a key 58 is used instead of a handle for withdrawing the latch from outside. In each case a key may be provided to enable the door to be opened from outside after the member 24 &c. is in a position to prevent it from being opened by the handle. This key may act either to withdraw the latch or to move the member 24 &c. out of the locking position. The Provisional Specification describes a modification of the arrangement shown in Fig. 7 in which the latch is withdrawn from outside by a wire attached to the latch and to the pivot 42. When the outer handle is turned the wire is wrapped round the pivot pin and withdraws the latch. In this case the electric circuit is closed by the pivot pin and also the locking means acts on the pivot pin.

Title: Fabrication of composite surfaces and structures
Inventor: WELTY LLOYD GARDNER
IPC: E01C7/35
Filed: 1960-02-09
Abstract: <PICT:0905988/III/1> <PICT:0905988/III/2> A method of fabricating a composite layered structure upon a substrate surface comprises applying a first layer of cinder-like aggregate particles so as to be bonded to the substrate surface in a partially embedded condition, and applying a filer layer of an aggregate/binder composition to said first layer.  In one example, cinder-like aggregate particles 5, Fig. 1, are partially embedded in a layer 4 of fluid adhesive applied as by spraying to a substrate 3 which may comprise concrete, asphaltic paving, wood, rock, brick, metal, foamed plastics &c.  After the layer 4 has set a cover layer 6 in a dough-like or semi-plastic state is rolled into the interstices between the particles 5, with or without the interposition of an adhesive bonding film 8 sprayed over the projecting particles 5.  Finally a dusting layer 7 of aggregate particles may be applied or rolled into the surface.  In Fig. 2 the layer 4 is omitted and the cinder-like particles 10 are partially embedded in a soft concrete substrate 9.  Tubing and panel sections may be constructed by applying the cinder-like particles to a suitably formed substrate base, by partially embedding these particles in a layer of fluid adhesive applied over the base when it is of metal, fibre or other sheet material or by partially embedding these particles into a substrate of glass fibre matting impregnated with resin or binder before the resin or binder has set.  A plastic composition of the cinder-like particles mixed with an adhesive binder is then applied over the layer of embedded particles and finally a covering layer of resin or binder impregnated glass fibre may be applied.  The cinder-like particles specified are of a volcanic origin.  The fluid adhesive in which the particles are embedded may be of the type which solidifies by evaporation of a solvent, such as solvent solutions of asphaltic, coal tar or other resinous materials, or of the type which solidify on cooling such as molten asphalts, coal tar, p  resins and synthetic resins, or preferably of a resinous catalyzed setting type such as catalyzed epoxy, phenolic, polystyrene, acrylic esters, resorcinal formaldehyde, polyurethanes, polyester and silicone resins which set at ordinary room temperatures.  The cover layer 6, Fig. 1, may comprise asphaltic or coal tar binding paving materials or the like when the invention is applied to roadway surfacing, but may also comprise a binder of the catalyzed resinous adhesive specified.  The surface layer can be provided with pigmented or light reflective aggregate particles.
