Abstract: 335. Battersby, R. Jan. 5. Potato diggers. -Relates to detail improvements in the machines described in Specifications No. 26,979, A.D. 1896, and No. 5371, AD. 1900. A rotary skeleton wheel 2 is mounted in front of the share D and at the side of the apron F, and tends to separate part of the soil from the potatoes and to guide the potatoes upon the apron F. The wheel 2 is driven by suitable gearing. The crossbar 9 of the grid E is formed with depressions between the bars of the grid, to facilitate the passage of the revolving forks C over the grid. Bars 10 are hinged to the bar 9, and rest upon the apron F so as to bridge over the interval between the grid and the apron. The portion of the machine comprising the apron F and the riddles, is mounted on a frame which can be detached from the main part of the frame and then attached in the position of the share D to reduce the width of the machine for purposes of transport. Arched angle-iron bars 17 are attached to the frame and to the side piece 18 of the apron trough, and serve to better support the apron F and to form a frame for the attachment of a canvas hood to prevent the soil and potatoes from being thrown out of the machine. The part 23 of the frame carrying the revolving forks C and the share D can be raised or lowered to adjust the depth of work or to raise the share out of the ground, by means of a screw 21 with hand-wheel 20 bearing against an arm 22 attached to the frame 23, and a supporting ground wheel.

Granted: 1901-11-23
Abstract: 754. Wolffenstein, R. Jan. 11. Cadmium oxides; magnesium oxides and salts; zinc oxides and salts.-Peroxides of zinc and magnesium are obtained by adding peroxide of hydrogen to alkaline solutions of salts of zinc or magnesium. If the alkali is present only in just sufficient quantity to allow precipitation to take place, basic peroxide salts are formed, e.g., if zinc sulphate is treated, a basic sulphate of zinc peroxide is produced. In order to obtain the peroxides in a finely-divided form, they may be mixed with other oxides or hydrates, such as alumina, which may conveniently be done by simultaneous precipitation with the peroxides. The Provisional Specification states that cadmium peroxide may be similarly produced.

Patent GB-190111001-A (GB)
Title: Improvements in or relating to Apparatus for Measuring Surface Area.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-05-28
Granted: 1902-03-27
Abstract: 11,001. Boult, A. J., [United Shoe Machinery Co.]. May 28. Calculating-apparatus in the form of a machine for measuring the area of fabrics. A pair of driven rollers, one of metal and the other of insulating-material, is geared through an electro. magnetic clutch 25 to an index hand for a dial 23 and through ordinary gearing to a switch which consists of an arm 18 revolving over a ring of stationary contacts separately wired to fingers 11 between the rollers. The clutch contains two opposing windings, one of which always has current flowing through it while the other receives current through the switch. When no current is so received, the clutch is in action and the index advances. A piece of cloth or leather running through the rolls prevents a greater or less number of currents for each revolution of the switch according to its breadth, and consequently allows the clutch to transmit a greater or less angular motion to the index. As one revolution of the clutch corresponds to a certain short length of the fabric and each contact finger to a strip of definite breadth, the travel of the index integrates the area. The index is returned by hand after each integration, and the number of pieces measured is recorded by a counter which it operates at starting. The index also drives by continuous gearing another counter which totalizes the areas, and, where the areas are individually read off the dial only to the nearest unit division, in order that the odd fractions may not be integrated by the counter, the gearing includes a friction disc 129 pierced by conical holes so as to be justified by a bevelled pin 135 which the index 24 pushes as it is returned to zero. The construction of the electromagnetic clutch is as follows. A disc 31, which is made up of an iron centre and outer ring separated by a brass ring, revolves with a cup 33 attached to the driving- shaft 20, and intervenes between a stationary annular horse-shoe electromagnet 36 and its armature 30, which is a disc attached to the shaft 29 to be driven. Another disc 41 on the driven shaft is the armature of an opposing larger electromagnet 35. Thus, with a continuous current through the smaller electromagnet, the rotary motion is transmitted when there is no current in the larger one, and is suspended when there is a current in it. The apparatus might comprise several indicators, one to each feeler device and all capable of operation synchronously with the web propeller.
