Title: Improvements in Calculating Scales or Slid Rules.
Inventor: SMITH RUDOLPH CHARLES
Filed: 1900-04-24
Granted: 1901-05-23
Abstract: 7579. Smith, R. C., and Cruickshank, J. April 24. Slide-rules.-Relates to improvements on the invention described in Specification No. 24,078, A.D. 1897. A cardboard calculating-scale or slide-rule is provided with means for indicating the order of tens in the result of a calculation. The scale 3 of the stationary body 16 has exponents affixed to its numbers, and the slide S<1>, S' is divided into two scales, and is guided by clamps 10 passing through perforations in the body of the scale and bent over the flexible transparent plates of the main body. At the middle of the slide is a dividing-line 11 and central line 12 on the transparent cover. On the slide S', S<2> and on the auxiliary slide 14 are engraved or printed columns of figures or conventional signs. Each sliding clamp 13 carries a flexible transparent plate, preferably of celluloid. A flexible transparent cover 18, attached to the back of the auxiliary scale by a clamp 15, may be placed between the flexible covers on the main rule. The auxiliary scale and slide are preferably of cardboard, enveloped in celluloid, held together by flexible plates, and having guiding-clamps 27. A sliding clamp 17 is provided to facilitate calculations. The slide 14 and its scale are graduated as shown. If the result of a calculation falls between the lines 11 and 12, the correspondingly-marked column on the slide 14 is used, while at other times the normal column is used. The figures on the left-hand half of the slide-rule are marked so as to show that their values are one-tenth of those marked on the right-hand half.

Title: Improved Method of Starting and Regulating Multiphase-current Motors.
Inventor: BOUCHEROT PAUL MARIE JOACHIM
Filed: 1900-05-24
Granted: 1901-05-18
Abstract: 9534. Boucherot, P. M. J. May 24. Transformers.-In a method of starting and regulating multiphase - current motors, special motors are constructed with the stator in two parts, one of which receives polyphase currents of constant phase, and the other corresponding currents of variable phase, difference being obtained by a "phase transformer." One form of the latter, which may also be used as a pressure transformer, is shown in Fig. 4. This comprises two parts 1, 2, the part 1 fixed and composed of sheet-iron discs 8 perforated for windings 12 for polyphase currents from the source, giving a rotating field, and the part 2 capable of rotation through a certain angle round an axis 6, and composed of sheet-iron discs 9 perforated for windings 13, which may be similar to the windings 12 unless it is required to transform the pressure. In a modification, shown in Fig. 6, one set of discs 8 receives both windings 12, 13, the latter being in the form of the armature winding of an ordinary continuous-current dynamo, and arranged with a commutator 14 and rubbers 15, which are moved round the axis 6 to give the phase transformation. When the pressure of the primary and secondary is the same, a single coil like the secondary 13 may be used, with fixed points connected to the source. The phase transformer may be used only at starting, or may be used as a pressure transformer for varying the motor couple in starting or in speed.

Granted: 1903-04-25
Abstract: 9623. Digre, H. W. April 25. Sewage, treating filtering.--Relates to siphon apparatus for regulating the supply to a filter. The sewage collects in a tank from which it is discharged automatically and intermittently to the bottom and top, alternately, of the filtering-tank. This is effected by a pair of siphons 1, 2, with a common bell 3, divided into two compartments by a plate 4. Each siphon is fitted with air pipes 6, 13, leading to the crown and outlet side of the trap, respectively. At the beginning one siphon has a full trap and the other a half one only ; thus the tank fills until the half seal is blown out, and the flush started. The flush is claimed to be delivered alternately by the siphons. The filtered liquid passes by a pipe 11 to a chamber containing the short leg of the siphon 8. It enters at the same time a bell 9, and compresses the air until the seal is blown out.
