Patent GB-1431135-A (GB)
Title: Universal joints
IPC: F16D3/223
Filed: 1974-04-26
Abstract: 1431135 Universal joints UNI-CARDAN AG 26 April 1974 [11 May 1973] 18317/74 Heading F2U In a homokinetic universal joint in which an outer joint member has an inner cavity provided with grooves and an inner joint member, grooves on its exterior surface, for the reception of balls, means are provided to increase the angle through which the plane containing the centres of the balls tilts relative to the axis of the inner joint member upon bending of the joint to compensate for manufacturing tolerances, wear or distortion of a ball cage under torque, all of which tend to decrease the angle, away from the theoretical plane containing the bisector of the angle between the axes of the inner and outer members. In a double offset joint, as shown in Fig. 6, a means to effect the decrease in the angle between the axis K-K of the cage 7 (this axis being perpendicular to that plane containing the ball centres) and the axis I-I of the inner member 10 comprises having the centre of the part-spherical surface 8 of the exterior of the cage (and of the interior 6 of outer member 5) further from the plane containing the ball centres than the centre of the part-spherical inner surface 9 of the cage 7 (and hence the partspherical outer surface of inner joint member 10). This imbalance effects the required compensation of the error due to clearances in the joint, if properly selected. In Fig. 8, an alternative method comprises the inclination of the sides of the apertures 16 in the cage 13 for reception of the balls, the angle α F  of these sides causing the required change of angle. In a universal joint in which the outer and inner surfaces of the cage have the same centre and the balls position themselves at the intersection of oppositely inclined ball grooves of the outer and inner members, the compensation for clearances is provided by inclining the ball tracks 20 of the outer member at a greater angle to the axis of that member, angle # SA , than the ball tracks 21 of the inner member are inclined to the axis of that member (and # SI ) (Fig. 9). Also described are complete joints incorporating these features (Figs. 10, 11 and 12, not shown), these having sealing boots.

Title: Thermosetting lignin-containing resin
Inventor: CAMBRON EMILE ADRIEN
IPC: C08G8/28
Filed: 1960-05-26
Abstract: Thermosetting resins are produced by first preparing in alkaline solution a substantially monomeric monomethylol acetone and successively reacting it in alkaline solution with (1) phenol and/or cresol and (2) formaldehyde to form a resin, to which water-insoluble alkali lignin is added.  In modifications, all or part of the lignin may be added to the phenol, or to the phenolmethylolacetone reaction product, before reaction with formaldehyde.  In Example (1) a water-dilutable laminating varnish is produced by refluxing acetone with formaldehyde in presence of sodium carbonate. Phenol is added with more sodium carbonate and finally more formaldehyde and sodium carbonate. The formalin and alkali are added separately and alternately in small portions.  Lignin caustic soda and methanol are added to the cooled product which is then used to impregnate Kraft paper for laminating.  (2) is similar but uses a mixture of phenol and cresol.  Specification 948,777 is referred to.

Title: Biologically active material
IPC: C05F9/02
Filed: 1976-05-07
Abstract: To produce the soil improvement material, organic wastes are comminuted, moistened with water or slurry and then compressed. The moistened waste materials are laid in layers one above the other on a soil conducting away water. Each individual layer is compressed and, with spacing, slots extending essentially to the vicinity of the soil are excavated from the layer block so formed. The installation for carrying out the process includes two walls (10) extending over the layer block length, arranged at a distance of the layer block width, between which walls is arranged soil (1) conducting away water. Furthermore, the installation includes movable devices (2, 3) such as suitable vehicles for laying the moistened waste materials (9) in layers on the soil or on top of each other, for compressing the layers (8), for cutting out slots (7) and for excavating the rotted material. The process and the installation enable the composting of very high amounts of refuse on relatively small areas, while the expenditure in terms of personnel and equipment can be kept extremely low. <IMAGE>

The more negative D.C. bias is applied during the " receive-re-create " mode since otherwise during the 60-second period needed for complete recording of the received information a series of like non-picture representative charges would accumulate throughout the target elements of the storage tube due to the repeated scanning thereof to thereby alter the ultimate pattern on the target, a controlled sampling technique being used to gate the beam to reconstruct the information on each scan. In the "receivere-create " mode charge is only laid down when the received amplitude modulated video pulses increase the bias voltage on the control grid to the first D.C. bias level. As shown the video signal is applied at input 10 and horizontal rate pulses at input 30.
