The back 20 of a settee is pivoted at 22 to swing upwardly and is connected by a strap 38, or lostmotion linkage, to the seat 26 so that the final movement of the back to horizontal position displaces the seat outwardly on its supporting rails 24 in which position it is retained, preferably by a roller 34 riding over a cammed stop 36. A link 30 supports the rear edge of the seat and a stay 40 can hold the back in partly raised position as shown, to give access to. bedding stored behind it, or in the fully raised position to fascilitate bedmaking. In a modification the link 30 is dispensed with and a cam on the rails 24 supports the rear edge of the seat in horizontal position; the actuating strap 38 can also be differently arranged.

Title: Improvements in or relating to governing apparatus for prime movers
IPC: G05D13/00
Filed: 1929-11-29
Abstract: 343,206. Engine governors. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, MORRIS, F., 32, Mulgrave Avenue, Ashton-on-Ribble, and HORNER, F. H., Willans Works, Rugby.-(Paulin, G. H.; 465, Calle Defensa, Buenos Aires.) Nov. 29, 1929, No. 36661. [Class 57]. A remote control system for altering the setting of a governor where it is desired to run a prime mover at any of several predetermined speeds for each of which there is a corresponding governor setting. A centrifugal governor 1 driven from the prime mover is loaded by a spring 6 and operates a pilot valve 12 of a power cylinder 11. The point of application of the spring 6 on the lever 5 is varied by rotating the quadrant 18 to which the spring box is connected. A power piston 20 is biased by a spring 21 and supplied with liquid through an inlet valve 22 actuated by a solenoid 23 and the pressure in the cylinder is relieved by an exhaust valve 24 also operated by a solenoid 25. The plunger rod 27 is geared to the quadrant 18 and also to a quadrant 28 attached to a control drum 26 carrying a number of contact strips a .. e, see Fig. 2. A master control switch 30 has contacts 1 .. 4, which, when turned in one direction energizes the solenoids 23 and 29 to lift the piston 20 and when turned in the other direction to energize solenoids 25 and 29 to open the exhaust valve 24 and lower the piston. The solenoid 29 operates to lift a brake on the drum 26. The solenoids are energized a length of time corresponding to the length of contact between the strips on the drum 26 and the contact on switch 30. Alternatively the governor setting means may be operated from one of two oppositely rotating shafts driven from the prime mover, clutches operated in a similar way to the valves 24 and 25 being employed. The Provisional Specification states that in a further modification a reversible electric motor similarly controlled may be used, provided with an electric clutch co-operating with the brake coils 29.

Title: Improved insulating composition applicable for coating handles and the manufacture of plates, rods, tubes and the like
IPC: C08G16/02
Filed: 1928-12-12
Abstract: 326,255. Schmidt, C. Dec. 12, 1928. Handles; coatings.-A coating material for han. dles of cooking-utensils &c. protective against heat, electricity, acids and lyes, and also suitable for the production of plates, rods, tubes, &c., is produced from ivory nut chips by adding the precipitate obtained from the treatment of the chips with concentrated sulphuric acid to the product obtained by the oxidation with permanganate of carbolic acid mixed with excess of ammonia and mixing the resultant solution with formaldehyde, the product being heated till hardened. The ivory nut chips are pulped with sulphuric acid, dissolved by heat, the liquid siphoned from the residue, precipitated by adding water and the precipitate dried. The raw carbolic acid is mixed with ammonia until milky and concentrated permanganate solution added, resulting in two liquid layers, the upper aqueous solution of manganous salt being drawn off leaving a brown black heavy oil. The latter is heated with a quarter of its weight of the ivory nut precipitate, and to the resulting solution is added one third of its weight of 35-40 per cent formaldehyde. Granulated calcium chloride is added for removing the water. The phenol aldehyde condensate becomes viscous on standing, and on heating to 160‹-170‹ C. becomes hard and resistive to acids. The process may be varied by pulping the ivory chips in alkaline combination with higher alcohols and adding the pulp to the phenol aldehyde condensate, the subsequent heating driving off first the water and then the solvents.

Title: Fertilizers
Inventor: BARCLAY KEITH SCOTT
IPC: C05B1/02
Filed: 1958-11-19
Abstract: Organic matter present in phosphates to be used in the production of fertilizers, and selected from the group consisting of superphosphate, triple superphosphate, monocalcium phosphate, dicalcium phosphate, monoammonium phosphate, and dicalcium phosphate is preoxidized by treating the phosphate with an oxidizingagent. This preoxidation prevents undue rises in temperature in the stored fertilizers. Preferably the treated material is stored for at least 3 days before being employed in the manufacture of fertilizers. Suitable oxidizing agents include nitric acid or ammonium nitrate, preferably in the form of aqueous solutions, which may be sprayed on to the phosphate, potassium permanganate, or manganese dioxide, for example, in the form of pyrolusite.  When solid oxidizing agents are employed, they may be mixed in finely divided form with finely divided phosphate rock prior to acid treatment, or with the acid which is to be used to dissolve the rock, in the production of superphosphate.

Title: A process for the oxidation of olefinic hydrocarbons
Filed: 1960-10-31
Abstract: Aldehydes and ketones, unsaturated in the a ,b  position, are produced by passing concurrently a suspension of a heavy metal-containing oxidation catalyst in a molecular oxygen-containing gas comprising steam and an olefinic hydrocarbon having at least 3 carbon atoms per molecule through an elongated reaction zone at 250-750 DEG C.; the catalyst is separated from the effluent from the reaction zone and passed while still at elevated temperature into a catalyst cooling zone of larger crosssectional area than that of the reaction zone and in open p  communication with that zone; liquid water and a continuous stream of molecular oxygen-containing gas are passed into the catalyst cooling zone thereby generating steam and forming a catalyst-containing gaseous effluent from the catalyst-cooling zone comprising molecular oxygen - containing gas, steam and entrained suspended catalyst; the suspended catalyst-containing effluent from the catalyst cooling zone is then passed into and through the reaction zone along with olefinic hydrocarbon. Preferably, at least part of the catalyst leaving the reaction zone is passed through a regenerating zone before being introduced into the catalyst cooling zone.  Suitable olefines for use as starting materials are, for example, propylene, isobutylene, 3-methyl-butene-1, 2-methyl-butene-2, cyclopentene, cyclohexene and 3 - methyl-cyclohexene.  If desired the olefines may be used in admixture with saturated hydrocarbons.  The molecular oxygen is preferably introduced into the reaction zone at a plurality of points and may be introduced into the system as relatively pure oxygen or as air or other gaseous mixtures, for example, with nitrogen, oxides of carbon or paraffinic hydrocarbons.  Suitable catalysts are, for example, tellurium oxide, alone or in combination with an oxide of molybdenum, tungsten or uranium; copper oxide in combination with various metals or metal selenites or tellurites; copper in combination with silica gel containing in addition Cd, Co, Mo, Th, Mn, Ca, Ti or Th; or selenium in combination with an oxide of Cu, V, Te, Cr, Mo, W, U, or Sn or with copper aluminate or silicate.  The catalysts may be supported, for example, on silica gel, alumina, silicon carbide or pumice.  The preferred catalyst is a mixture of the oxides of bismuth and molybdenum, especially when modified by phosphorus or compounds of phosphorus.  Specifications 912,686 and 912,688 are referred to.  Reference has been directed by the Comptroller to Specification 821,999.
