Thereafter the fish may then pass on to a pair of rotary cleaning brushes 60 raised and lowered alternately by a cam 64. Fixed brushes may also be provided behind the guide 23 and also behind the rotary brushes 60. The gill cutter has radially disposed blades with concave recesses leaving cutting edges at their ends.
Patent GB-736413-A (GB)
Title: Improvements in and relating to the manufacture of sebacic acid
IPC: C07C51/00
Filed: 1952-07-10
Abstract: Sebacic acid is obtained by reacting an alkali metal soap of ricinoleic acid, if desired in the presence of added water, at elevated temperature with caustic alkali, the mixture being dissolved in a fatty acid alkali metal soap which is liquid at said elevated temperature.  The ricinoleic acid soap may be formed in situ from castor oil and the caustic alkali.  If castor oil is used it is preferred to add an amount of water corresponding to that which would be formed if free ricinoleic acid had been used instead, by neutralization of the acid with the caustic alkali. The preferred caustic alkalis are caustic soda and caustic potash. Suitable fatty acid alkali metal soaps are those of soap forming natural or synthetic fatty acids having straight or branched chain structures. These soaps may be made in the course of the reaction either by alkaline oxidation of the corresponding alcohol or by alkaline degradation of unsaturated hydroxyl-group-free fatty acids, allowance being made for the alkali consumption involved. The reaction may be carried out at 200-350 DEG  C. and is preferably carried out in the presence of cadmium or a cadmium compound or in a cadmium coated autoclave.  In examples the reaction components are heated with stirring in a copper-lined steel autoclave and at the end of the reaction the pressure is released and the contents dissolved in or diluted with water.  The pH of the resulting solution is adjusted to a value of 6 to precipitate monobasic fatty acids and the octanol formed is driven off with steam. After removing the precipitated fatty acids the solution is acidified and cooled to yield sebacic acid.  In the three examples given the starting materials are (1) and (2) castor oil, soyabean fatty acids, caustic soda, water and cadmium oxide; (3) castor oil, a mixture of fatty alcohols from whale oil, caustic soda, water, and cadmium oxide.  In each case the ricinoleic acid alkali metal salt and the fatty acid alkali metal soap are formed during the reaction.  Specification 698,154 is referred to.

Filed: 1925-07-08
Abstract: 236,946. Siemens - Schuckertwerke Ges. July 8, 1925. Addition to 236,944. Wire ropes; machines for making.-Two sets of conductors a, b are arranged on opposite sides of a triangular plate 7. The conductors are bent from one side of the plate 7 to the other by levers 1, 2 and then across the plate by levers 3, 4 so as to produce a cable of the form shown. Cam-actuated levers 5, 6 support the conductors while they are being bent by the levers 1, 2 and are then moved out of the way of the levers 3, 4. When a pair of conductors has been bent by the levers the cable is moved on to present the next pair to the levers 1, 2 by a pawl 9, Fig. 3, engaging with a series of holes in a slide 19. The levers 3, 4 press the conductors against side plates 104, 105, Fig. 6, against which they are held, when the levers withdraw, by plates 102, 103. The plates 102, 103 are hung on links and moved out of the way of the levers 3, 4 by a cam. The levers 1, 2, 3, 4 and the pawl 9 are also actuated by interconnected cams.

Title: Improvements in and relating to time fuses for projectiles
IPC: F42C19/02
Filed: 1918-10-28
Abstract: 139,531. Ohlson, O. Jan. 5, 1918, [Convention date]. Projectiles; projectile fuses.-Relates to time fuses, and more especially to mechanical time fuses comprising a setting-member such as the member 11 which is rotated to set the timing-ring 13 of a clock-work. According to the invention, combined means are provided for limiting the rotation of the setting-member during the setting operation, and for locking it against rotation when the projectile is discharged from a gun. These means comprise a pin 35, Fig. 5, depending from the setting-member 11 and coacting with stops 34 on a ring 31, Fig. 6, which is prevented from rotating by wedges 30, 30<a> fitting into notches 33 in the base 10 of the body of the fuse. The stops limit the rotation of the setting-member, and the wedges 30, 30<a> bind between the setting-member 11 and the base 10 of the fuse body when the ring 31 sets back on the projectile being discharged. The wedges 30, 30<a> are made of different shapes or forms, or are irregularly spaced to ensure the correct positioning of the ring 31 and stops 34. The setting-member 11 is made with a shoulder 36 which prevents assemblage until the ring 31 is correctly placed; and the setting-member is retained in the assembled position by a wire 19. The timing-disk 13, Fig. 2, has (1) a notch 21 adapted to be brought to, and engaged by, a trip catch 23 to release the strikerof the fuse at the given time, and (2) another notch 28 engaged by a spring blade 14 which couples it to the setting- member 11 until the projectile is discharged, when the spring blade 14 moves out by centrifugal force to allow the timing-disk to-be driven forwards in the direction of the arrow; backward rotation of the disk due to its inertia while the rising of the gun is imparting rotation to the projectile is prevented by the coupling-blade 14 which, even when swung out by centrifugal force, still lies in the path of a projection 29 on the disk. The limitation of the rotation of the setting-member serves to prevent the notch 21 or the blade 14 from being brought against the trip lever 23 when the fuse is being set. The fuse is covered by a hollow cap 12, which is made with a flange 38 sprung over a shoulder 39 on the fuse, or is attached to the fuse by screws. This cap is finely tapered to diminish air resistance. The clockwork fuso is more fully described in Specification 138,370.

If the parts 3 are of cork additional damping may be provided, such damping comprising a rubber or like pad in frictional engagement with the coil, or immersion of the coil in oil. The parts 3 may have a slight initial tension or compression.
