Title: Improvements in a method for ensiling vegetable and animal products
IPC: A23K3/03
Filed: 1953-02-16
Abstract: A method of ensilage comprises the admixture, with the fodder, of a double acid salt of an alkali-metal of the general formula RH5 (PO4)2, n RHSO4, where n lies between 1 and 3.  The salt, or a mixture of such salts, or a mixture of simple salts in suitable proportions, is added in such a quantity as to maintain the pH value of the silage between 4.0 and 4.5, 1-2 per cent being generally sufficient to produce this result, thereby inhibiting bacterial action and reducing the content of butyric acid in the silage.  The method may be applied to the preservation of urine or manure from undesirable bacterial action; the press-juice from the silage may be used for the same purpose. Specification 430,417 is referred to.

Abstract: 702,464. Feeding webs; feeding sheets. FORGROVE MACHINERY CO., Ltd., PARKER, M., and HARRIS, R. A. Dec. 3, 1951 [Feb. 22, 1951], No. 4323/51. Class 100 (1) Feelers and detectors; faulty feed control devices.-A wrapping machine comprises mechanism for feeding wrappers 35 in succession to bring their leading edges to a datum position on a member 37 formed with a hole 63. A feeler 41 is disposed opposite the hole and at the side of the wrapper remote from the member 37, and a normally cocked trip member 47, which, when uncocked, operates by snap action to actuate a device 64 for stopping the machine and to retain the device 64 in actuated position, is actuated thereby in the absence of a sheet or wrapper below the hole. The member 37 is disposed opposite a member 38, the feeler 41 being located in a hole in the member 38. The members 37, 38 are carried by a lever 39 pivoted at 40 for slight clockwise movement under the action of a lever 60 operated by a cam, Fig. 2 (not shown). The feeler 41 is mounted on an arm 42 of a bell-crank lever pivoted at 43 on an extension of the lever 39. In the presence of a sheet, when the lever 39 is oscillated the arm 42 of the bell crank lever is constrained to move therewith so that a striker 44 on the other arm 72 of the lever remains clear of the trip lever 47. If there is no sheet present between the holes in the members 37, 38, as the lever 39 is oscillated the feeler 41 will enter the hole 63 in the member 37 under the action of a spring 45 and owing to the pivoting of the bell crank lever with respect to the lever 39 the striker 44 will move upwardly to contact the lever 47 and rotate a shaft 48 in a clockwise direction. Rotation of the shaft 48 causes a lever 49 to actuate a switch 64 to stop the machine and causes a lever 50 having a nose portion 54 to move clear of detent 55 which springs to the right under the action of a spring 57 to maintain the trip mechanism in the operated or uncocked position. Recocking is effected by a knob 71. The wrappers may be cut from a web fed as described in Specification 622,593, [Group XVII], or may be fed as separate sheets The wrapping machine may be as described in Specifications 565,144 and 688,506, [both in Group XVII].
