Abstract: 388,998. Altering physical or molecular structure by mechanical treatment. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(United States Pipe & Foundry Co. ; Burlington, New Jersey, U.S.A.) July 22, 1932, No. 20702. [Class 83 (iv).] The injurious strains in the bodies of metal castings or forgings are modified or eliminated by subjecting the bodies to high pressures simultaneously exerted on all parts of the bodies without materially changing the form of the bodies, the required pressure for each type of body being determined experimentally. The pressure is preferably applied hydraulically and varies from 3,000 to 150,000 lbs. per square inch, the metals with higher tensile strength and elastic limit usually requiring the higher pressures. The pressure required may be determined by observing which pressures prevent the introduction of strains in the castings &c. or by testing thin sections of specimens which have been subjected to different pressures. An apparatus for carrying out the invention is shown in the Figure, the castings &c. F being supported on a cage E inside a chamber A which is closed by a cover D and supplied with pressure from an accumulator C.

Title: Polyhydric alcohol esters of 2,2,3-trichloropropionic acid
IPC: C07C69/63
Filed: 1957-07-01
Abstract: The invention comprises the fully esterified reaction products of 2:2:3-trichloropropionic acid with aliphatic polyhydric alcohols. The reaction is carried out by heating together the 2:2:3-trichloropropionic acid and the polyhydric alcohol, preferably with removal of the water of reaction as rapidly as it forms either by operating under reduced pressure or by azeotropic distillation using a water-immiscible solvent such as ethylene dichloride, monochlorobenzene or toluene.  Sulphuric acid may be used as a catalyst.  Specified polyhydric alcohols other than those specified in examples are triethylene glycol, tripropylene glycol, tri-(trimethylene) glycol, hydroxyethoxy-propanol or ethanol and hydroxyethoxypropoxy-propanol or ethanol.  The compounds are used as herbicides and parasiticides (see Group VI).  In examples diethylene glycol is heated with 2:2: 3-trichloropropionic acid and ethylene dichloride with continuous removal of water by distillation to give diethylene glycol, bis(2:2:3-trichloropropionate) and the esters of the following alcohols are prepared similarly: ethylene, propylene, trimethylene and di-propylene or trimethylene glycols; 1-(21-hydroxyethoxy)-2-propanol; glycerol, erythritol and pentaerythritol.  The preparation of certain polyhydric alcohols is also described.  Thus, 1-(21-hydroxypropoxy) - 2 - propanol may be prepared by reacting 1:2-propanediol with propylene oxide in the presence of sodium hydroxide; 2 - (21 - hydroxypropoxy) - 1 - propanol may be prepared by reacting 1-methoxy-2-propanol with propylene oxide to give 1-(21-methoxyisopropoxy)-2-propanol and treating this with hydrogen bromide; 2-(21-hydroxy-11-methylethoxy) - 1 - propanol may be prepared by reducing 1 : 11-dicarboethoxy-diethyl ether with lithium aluminium hydride and di- and tri-(trimethylene) glycols may be prepared by heating 1 : 3-propanediol in the presence of iodine.ALSO:The fully esterified reaction products of polyhydric aliphatic alcohols and 2 : 2 : 3- trichloropropionic acid (see Group IV (b)) may be used as herbicides and parasiticides.  Thus they may be diluted with inert finely-divided solids and the mixture used as a dust or dispersed in water as a spray.  They may also be used in oil-in-water emulsions with or without a wetting or emulsifying agent.  Specified compounds include diethylene glycol bis-(2 : 2 : 3-trichloropropionate), propylene glycol bis-(2 : 2 : 3-trichloropropionate) and crythritol tetrakis - (2 : 2 : 3-trichloropropionate).

Abstract: 712,191. Seaming non-metallic sheet material. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 13, 1952 [Sept. 5, 1951], No. 20941/51. Class 42 (1) Transverse seams are formed between two or more continuous, superimposed layers of thermoplastic film, particularly polythene, by passing them from a feed roller past a tensioning roller or bar to a take-off roller. interrupting at intervals the passage of the film layers and, while the film is stationary, bringing the film layers at the tensioning roller or bar and, a substantially linear radiant heating element into such juxtaposition relative to one another, and holding them in juxtaposition for such a period that the layers become, sealed together across their width without contact of the heating element with the film, the tension of the film in, the seaming region being increased for the duration of the heat-sealing step by displacement of the stationary film relative to the tensioning .roller or bar at each side thereof. As shown, superimposed layers of film 1, which may be a single length of tubular film in flattened form, pass between a feed roller and a take-off roller over a tensioning,bar 2 extending across the width of the film and supported on a cooled steel plate. Movement of the film is interrupted at set intervals and an electrically-heated bar 4, insulated in a support 5, is lowered, together with two cooled steel blocks 6, under spring loading so that when bar 4 reaches its closest approach to the film blocks 6 press the film against plate 3 and thereby increase the tension of the film over bar 2. When the film below bar 4 has softened sufficiently under radiant heat for a seam to be formed, the bar and blocks are raised and the film is moved into position for the next seam. The apparatus may be modified so that bar 4 is held stationary while the film is moved towards it by movement of bar 2; or the means for displacing the film may be adapted for horizontal. as well as vertical movement so that they press. the film against the sides of bar 2 during seaming.

Abstract: 869,864. Rotary wing aircraft. UNITED AIRCRAFT CORPORATION. July 2, 1958 [July 25, 1957; Sept. 3, 1957], No. 21164/58. Class 4. Apparatus for ensuring that all blades of a rotary wing aircraft shall track uniformly comprises a rig 10 containing an engine 12 driving a rotor head 14 through a transmission 15. The rotor head includes conventional root sleeves 92 for the rotor blades, the sleeves being rotable about their axis in known manner by pitch-charging horns 94 and connecting rods 100, swashplate mechanism 28, 30 and pitch control rods 17. Each rod 100 comprises an internally threaded sleeve 102, a lower ball-ended extension 104 and a similar upper extension 106 which, together with the cooperating end of the sleeve is graduated to form a micrometer adjusting scale. Both extensions may be locked to the sleeve, the lower one being used for coarse adjustment of length, the upper one for fine adjustment in the manner to be described. A tool 150 which comprises two arms at right angles having connections respectively for attachment to the blade atatchment points on sleeves 92 and the connection of rods 17 with the swashplate non-rotatable element 28 is used to ensure that all sleeves 92 have the blade root attachment fittings set at the same incidence. This is done by setting the micrometer reading on the rods 100 at zero and adjusting the extensions 104. The rotor blades to be tested are then assembled on the rotor head and the rig set in motion to enable the blades to aerodynamically and dynamically balance, any variation of pitch required on individual blades to ensure uniform tracking being provided by adjustment of the micrometer element of rods 100. The resulting variation from zero of micrometer reading is marked on the individual blades so that when assembled on a production rotor head they may be given the same pitch setting as that determined on the test rig. In an alternative embodiment, the micrometer elements on rods 100 and the tool 150 are dispensed with and instead a protractor incorporating a spirit level is used to determine the pitch of each sleeve 92 after the blades have been tracked. The variation from a level or zero reading is marked on each blade and the pitch of individual blades is adjusted on the production rotor by rods 100 to set the blades at their appropriate pitch settings. Specification 713,352 and U.S.A. Specification 2, 759, 359 are referred to.
