Patent GB-395004-A (GB)
Title: The manufacture of metal-organic complex compounds
IPC: C07F9/90
Filed: 1932-01-07
Abstract: Complex compounds of antimony with aliphatic polyhydric alcohols are manufactured by reacting upon an aliphatic polyhydric alcohol with a salt, oxide or hydroxide of tri- or pentavalent antimony in the presence of an alkali or alkaline-earth metal hydroxide.  Suitable alcohols are glycerine, erythrite, xylite, sorbite, dulcite and mannite.  The complex compounds may be precipitated by heating or by precipitation with, for example, alcohol.  The alkaline-earth metal salts of the antimony complex compounds may be transformed into the corresponding alkali metal, tetraalkylammonium or alkylene diamine salts by the action of the calculated quantity of an alkali metal, tetraalkylammonium or alkylene diamine salt the anion of which forms insoluble or sparingly soluble alkaline-earth metal salts, e.g. the salts of sulphuric, oxalic or carbonic acid, such as sodium or potassium sulphate or bisulphate, carbonate or bicarbonate, or oxalate.  In examples: (1) antimony oxide (Sb2O3) is added to a solution of sorbite in aqueous caustic soda, to produce sodium antimonyl sorbite, of the formula Na[C12H26O13.Sb] aq. or Na[C12H24O12.Sb] aq., which is precipitated by addition of alcohol; (2) antimony oxide is added to a solution of mannite in aqueous barium hydroxide solution, yielding a precipitate of barium antimonyl mannite, of the probable formula Ba[C12H26O13. Sb]2 aq. or Ba[C12H24O12.Sb]2aq.; by treating an aqueous solution of this salt with sodium sulphate there is obtained the sodium salt, of the probable formula Na[C12H26O13.Sb]aq.; by replacing the antimony oxide by antimonic acid there is obtained a compound of pentavalent antimony.

Title: Twin feed ammunition conveyor for feeding shells to an automatic weapon
IPC: F41A9/37
Filed: 1974-03-20
Abstract: 1445805 Automatic weapon ammunition feed FRANCE ARMED FORCES - MINISTER OF 20 March 1974 [3 April 1973] 12477/74 Heading F3C Shells from either of two strips are fed to an extraction station E of a conveyer having a star wheel rotor 3a, 3b on either side of a centre line, which extend through to a forward distribution station D having a central location for shell introduction to a firing chamber and lateral standby stations on either side which receive shells from the extraction station. Selective coupling of one rotor to a common drive mechanism causes a wheel 5a or 5b with an even number of teeth to move the corresponding shell from its standby location to the central location. A corresponding set of diametrical pushers 6a or 6b of half the number of wheel teeth have shoes 7a or 7b which bear over a portion of the pusher travel against a cam in order to move the corresponding shell into the central location and hold the shell with a pusher associated with the other rotor. Upon return of an open breech of the weapon leading shells of both strips are moved forwardly by pushers 1a, 1b from the extraction station E to the standby locations; a selector 4 determines which shell will be fired, this coupling the corresponding rotor 3a or 3b to the drive to move a pair of star wheels 5a or 5b on a rotor, and a pair of diametric pushers 6a or 6b with shoes 7a or 7b, the shoes abutting a corresponding fixed cam 8a or 8b and a pivoted cam piece 9 (for both rotors) so that the shell is moved into the central location C by a shoe 7a or 7b; furthermore, a pivoted member 10 is moved by the shell against a centralizing spring to lock the associated star wheels from movement until the shell is fired. Movement of the selector 4 to the opposite position provides movement for the shells of the other strip for firing.

Title: Improvements relating to slicing machines
IPC: B26D7/02
Filed: 1928-04-28
Abstract: 305,416. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmaclaines Volgens van Berkel's Patent en van Andere Werktuigen). April 28, 1928. Cutting slices in succession.-A clamp for a slicing-machine comprises a post 20, a clamping bar 23 projecting rigidly from a sleeve 22 slidable on the post, a one-way clutch for locking the sleeve against upward movement and a friction device which prevents the bar and sleeve from sliding down by their own weight. The clutch consists of a plate 32 apertured to receive the post 20 and provided with an extension 37 lying beneath a handle 26 projecting from the sleeve 22. The plate 32 which rests on a lug 33 on the lower part of the sleeve 22, is pressed downwards by a spring 35 bearing on a plunger 34, and by a spring 40 bearing on the extension 37. Normally the plate 32 jams against the post 20 and resists upward movement of the sleeve 22, it being necessary to move the extension 37 upwards to free the clutch for upward movement. A forked end of the handle 26 engages a post 21 and prevents rotation of the clamp on the post 20. The friction device comprises a spring-pressed plunger 28, fitted into cue arm of the fork, which bears against one side of the lost 21, and prevents the clamp bar from falling unintentionally, and takes up wear between the other arm of the fork and the post. If the post 20 is sprung during the clamping operation, it remains sprung, in opposition to the upward force of the meat, during the whole period of use, inasmuch as the hand pressure on the handle 26 exerts no springing force on the post 20, the springing being effected solely by the upward pressure of the meat. Springing back of the post, and consequent release of the meat, when the hand pressure is removed is therefore avoided. To permit springing of the post 20 without causing binding of the fork on the post 31, the fork is pivoted to the handle 26, or, alternatively, the top and bottom edges of the fork are rounded off. In a modification, Fig. 6, the handle 50 is set at an angle to the arm 57 which connects the posts 20, 21 and is secured to the sleeve 22 by bolts 59. This arrangement permits the posts 20, 21 to be close together. The clutch-releasing member is secured to the clutch plate by a screw 53 and is pressed down by a spring 54. The clutch plates may be made of softer material than the posts, and their apertures may be rounded to prevent scarring of the posts.
