Filed: 1920-09-06
Abstract: 172,697. Melhuish, A. E., (Albatross Ges. f³r Flugzeugunternehmungen). Sept. 6, 1920. Pneumatic springs.-A shock-absorber for aircraft consists of a pneumatic cushion interposed, without means for restraining lateral movement, between the part receiving the shock and the part to be cushioned. A sheath g of leather or the like is secured between a plate o on the frame n and a sleeve k on the axle l. The sheath contains a rubber bag h having an inflating valve i, the bag h being inserted through a hole m. The reaction of the cushion increases with relative movement owing to the sleeve k being pressed into the cushion. The sheath may be made of canvas, metallic fabric, or a set of chains or ropes. Reference has been directed by the Comptroller to Specification 9997/14, [Class 4, Aeronautics].

Title: Data processing apparatus

Filed: 1976-06-22
Abstract: 1535283 Memory checking INTERNATIONAL BUSINESS MACHINES CORP 22 June 1976 [15 Aug 1975] 25783/76 Heading G4A In a hierarchical (virtual) memory system the m-bit block (page) part of a virtual address from source 10 is fed to an associative translator array 12 for comparison with the corresponding part of the virtual addresses of those pages currently in the fast store. The comparator C producing a match causes encoder 13 to produce an n-bit address identifying the real page in the fast store containing the required virtual page. The n-bit address also accesses a check array 17 containing registers whose contents are the same as those of the translator array 12. The output of the check array is compared 19 with the original virtual address to check for correct operation. When no match occurs replacement logic 14 which monitors the output of encoder 13, identifies the least recently used translator register and initiates replacement. A match thus results and the check ensures that the translator and check arrays have been properly loaded.

A twin output clutch between a driving element 16, Fig. 1, and two coaxial shafts 18, 19 which are declutched sequentially by the same actuator comprises a first friction plate 12 connected to one shaft, an intermediate plate 12 connected to one shaft, an intermediate plate 13 which is displaceable up to a fixed abutment 36, a second friction plate 14 connected to the other shaft, a pressure plate 15, a cover 11, springs 20 interposed between the pressure plate and the cover and springs 30 interposed between the pressure plate and bearing elements 31 which are connected to tie-rods 32 each fastened rigidly to the intermediate plate and traversing a passage in the pressure plate. Operation.-When bearing 26 is moved in the direction of arrow 50 a ring 25 pivots levers 22 to move the intermediate plate 13, the friction plate 14 and the pressure plate 15 against the springs 20. Friction plate 14 remains clamped between the two plates 13, 15 due to the loading of springs 30 whilst the friction plate 12 is progressively declutched from the friction surface of the driving element. When the projections 13A engage abutment bars 36 the continued pivoting of levers 22 moves only pressure plate 15 to declutch friction plate 14. Flexible fastenings 42A, 42B are positioned symmetrically about an axial plane and are secured to the cover by two screws (43A, 43B), Fig. 2 (not shown), having a shared locking device (44) with its edges swaged over the screws. The bearing elements 31 are retained by lock-nuts 47 which incorporate a locking strip (49), Fig. 5 (not shown), which is swaged into slots 46 in the tie-rod ends.

Title: Process of sulfonating alkaryl hydrocarbons
Inventor: SMITH JOHN HENRY
IPC: C07C303/06
Filed: 1958-08-12
Abstract: Alkaryl hydrocarbons are sulphonated by dissolving the alkaryl hydrocarbon in sulphur dioxide, adding the resultant solution to the first compartment of a multi-compartment sulphonator under sulphonating conditions, together with sulphur trioxide diluted with sulphur dioxide in an amount insufficient to completely sulphonate the alkaryl hydrocarbon, passing the partially sulphonated alkaryl hydrocarbon successively through the compartments of the sulphonator, sulphonating with sulphur trioxide diluted with sulphur dioxide in each compartment, the proportion of unsulphonated hydrocarbon being progressively decreased and the sulphonation completed in the last compartment. Reaction temperatures of 50 DEG  to 60 DEG  C. are preferred.  Specified alkaryl hydrocarbons include the alkylation products of benzene, naphthalene, diphenyl and chlorobenzenes and -naphthalenes.  An apparatus for carrying out the process having a three-compartment sulphonator and the sulphonation of dodecylbenzene therein is described.

Title: Resol resins
Inventor: FRASER DONALD ALEXANDER
IPC: C08G8/28
Filed: 1954-09-10
Abstract: Resol resins are made by condensing a molar excess of a phenolic material with formaldehyde in the presence of an oxide or hydroxide of a divalent electropositive metal at a pH of from 4 to 7 to produce a non-heat-hardenable novolak, reacting this resin in the liquid phase with formaldehyde in the presence of alkali at a pH above 7 and stopping the condensation before the resol becomes insoluble.  The molar ratio of condensed formaldehyde to phenol in the product is greater than 1 : 1.  The phenolic material comprises phenol, meta-cresol, metaethyl phenol and mixtures thereof amongst themselves or with other phenolic compounds.  The oxides or hydroxides exemplified are those of barium, strontium, calcium, magnesium, manganese, zinc, cadmium, coblatous cobalt, lead, iron, chromium, tin and nickel.  Alkali condensing agents specified for the second stage comprise in addition to the oxides and hydroxides enumerated above, alkali metal carbonates, ammonia and organic bases.  In the example, 3000 parts of phenol, 658 parts of 36.35 per cent aqueous formaldehyde and 30 parts of Cd(OH)2 were refluxed and the water allowed to distil off to a temperature of 160 DEG  C., the phenol then being removed by vacuum distillation.  265.7 parts of the resultant novolak were mixed with 285.5 parts of water and 62.8 parts of NaOH, 167.5 parts of formalin added to the solution which was heated to 95 DEG  C.  The product was suitable as an adhesive for plywood.
