Abstract: PCT No. PCT/CH79/00104 Sec. 371 Date Mar. 21, 1980 Sec. 102(e) Date Mar. 20, 1980 PCT Filed Jul. 18, 1979 PCT Pub. No. WO80/00249 PCT Pub. Date Feb. 21, 1980.In the production of a body of filled plastics material, it is started from a self-supported article with open pores which can be obtained in the conventional manner. A reaction material is placed in the pores of the molded article. The pores of the molded article are sealed prior to final hardening. This can be done by means of an ultraviolet radiation source. Prior to sealing, the molded articles, without the danger of leakage of the reaction material, can be temporarily placed in a glycol/glycerol bath. The polyester resin of the coating is irradiated with UV through the glycol or glycerol bath.

Abstract: Take-off performance of an aircraft is dependent upon a number of factors including total load weight and load distribution, In some instances a special supervisor is required to supervise loading and enable trouble-free take-off. Alternatively load transducers mounted on the undercarriage and monitored in the cockpit have been used in the past. However, these take no account of any slope which the aircraft may be parked upon. 
     According to the invention a load indicator for an aircraft having an attitude meter and supported by undercarriage support members when parked includes: a plurality of load transducers, 1,2 and 3, for mounting on the support members with outputs connected to a computing unit, 4, which also has an input for connecting to the attitude meter, 5, and a load indicator display, 12, connected to receive an output from the computing unit and display aircraft load weight. 
     The inventive load indicator therefore automatically takes account of slope. 
     Additional inputs to the computing unit may be introduced to take account of eg air temperature, altitude. 
     The load indicator display may indicate the maximum all-up-weight point and also give a centre of gravity display.

Abstract: A process for preparing fatty acid esters by reacting olefins, aklanols and carbon monoxide in the presence of a compound of cobalt and a promoter consisting of pyridine, non-orthosubstituted alkylpyridines or mixtures thereof. The reaction output is at first treated with a gas containing oxygen in a non-damaging manner and then reprocessed in two distillation stages. The first distillation stage is operated at a higher pressure than the second. In the first distillation stage there is produced a distillate free of cobalt and a sump product containing all of the cobalt used as catalyst. In the second distillation stage the sump product of the first distillation stage is again distilled to produce another distillate free of cobalt and a cobalt concentrate as sump product. This cobalt concentrate is incorporated into pyridine, a non-orthosubstituted alkylpyridine or a mixture thereof to form a suspension. The suspension is then treated by a mixture of carbon monoxide and hydrogen at a temperature of 100 DEG  to 250 DEG  C. and a pressure at least 50 bars, and this treatment product is fed back into the fatty acid ester synthesis.

Abstract: Characteristics of two items in a sample are determined by sequentially adding first and second reagents and optically measuring characteristics of the first and second reaction solutions so obtained. 
     For example, transparent containers (2) are supported on a rotatable disc (1). A fixed volume of serum is introduced into one of the containers (2) by means of a pipette (9). The first reagent solution containing a-ketoglutaric acid, L-aspartic acid and NADH is introduced by the pump (9) so that an enzyme reaction caused by GOT in the serum proceeds. The container (2) is passed a plurality of times across an optical path (13), and variation with time of difference between absorbance at 340 nm and 376 nm is measured to determine a reaction rate for the first reaction solution. 
     Thereafter, the second reagent solution containing L-alanine is introduced by the pump (10) so that an enzyme reaction caused by GPT proceeds, and the reaction rate of this second reaction solution is determined in the same manner. Activity of GOT in the sample is determined from the reaction rate of the first reaction solution, and the sum of activities of GOT and GPT is determined from the reaction rate of the second reaction solution.

Abstract: Relatively-rotating face ring-type shaft seals, which are. especially suitable for sealing the shaft bearings and lubricant chamber of mud-motor-driven downhole drill rigs, have telescoped annular seal rings (123, 124) slidably mounted in a annular carrier element (122) and riding over the radial face on a face ring (112), defining a sealed intermediate chamber which may be filled with lubricant. Either the telescoped seal rings (123, 124) or the face ring (112) rotates with the bit shaft (15). Biasing means, such as a plurality of springs (143), urge the seal rings (123, 124) against the face ring (112) and pressure transmission means, such as pistons (152), mounted either in the carrier element (122) or the face ring (112) are loaded by the pressure of the ambient medium, such as drilling fluid, to maintain pressure in the intermediate chamber responsive to the pressure of the ambient medium. When the parts of the pressure transmission means exposed to ambient pressure and to intermediate chamber pressure are equal, a zero or negligible pressure differential will be maintained across the outer seal ring (124), to prevent the ambient medium from entering the outer seal ring interface. The inner seal ring (123) serves as an auxiliary back-up face ring seal for the protected bearing chamber. Since the abrasive medium does not enter the interfaces of the rings, the end faces (123', 124') of the seal rings (123, 124) riding on the face ring (112) can be reduced or narrowed to a minimum and coated with a hard facing material such as tungsten carbide.

Abstract: Heavy petroleum oils, such as vacuum resids and heavy fractions of tar sands and shale oil, are partially converted to more volatile hydrocarbons by mixing with light aromatic hydrocarbons and treatment of the mixture with a transalkylation catalyst, for example a Friedel-Crafts catalyst such as aluminum chloride. It is believed that the conversion is essentially a transalkylation, i.e. the resid undergoes dealkylation with concurrent alkylation of the light aromatic hydrocarbon.
