Title: Improvements in delivery mechanism for use in delivering the products of printing machines in counted batches
IPC: B65H33/10
Filed: 1933-08-16
Abstract: 424,422. Delivery apparatus for printing-machines. QUICK, C. G., BALL, D. A., and WHITEHEAD, W. A., 109, Borough Road, London. Aug. 16, 1933, No. 22910. [Class 100 (i)] Apparatus for delivering printed products in counted batches comprises a rotary fly 3 which deposits the products in a conveyer 24 moving in the same general direction as the delivery side of the fly, and abutment means which eject the products from the fly and cause count products to fall at a later time in the rotation of the fly than the other products. The abutment means consist of discs 6 mounted on a shaft 7 and engaging between the arms 2 of the fly to cause products to fall therefrom on to the conveyer 24, pockets 8, 9 being provided in the discs so that when the pockets are adjacent to the arms 2, the product carried by the fly is allowed to travel farther before being caused to fall, thus separating the products into counted batches. The depth of the pockets can be varied by means of arms 25 on the shaft 7. By making the arms independently movable, one of the pockets can be completely closed if desired. Further, the shaft 7 is carried by arms 26, 27 operated by a rod 28 and handwheel 29 so as to adjust the position of the discs 6 circumferentially of the fly. The drive for the shaft 7 consists of a worm 14<1> on the fly-shaft 4 engaging a wormwheel 14 on a sleeve 13 rotatable on a spindle 16 and having thereon a worm 12 engaging two wormwheels 10, 11 either of which can be clutched to the shaft 7. A cam 23 fixed to the shaft 7 rocks a lever 20 pivoted at 21 and attached to the spindle 16 so as to give the spindle and the worm and wormwheels 14, 12 an axial movement in addition to the rotary movement. The discs 6 are thus caused to move slowly while the circular parts thereof are operating on the products, but are accelerated when the pockets 8, 9 come into operation. A clutch device on the shaft 7 can be operated to cause either the gear 10 or the gear 11 to drive the shaft so as to vary the number of products in each batch. The worm 141 can be manually adjusted along the shaft 4 to vary the setting of the discs 6. Specification 333,287, [Class 100 (ii)], is referred to.

Title: Improved process for the rapid energising of magnets
IPC: H01F13/00
Filed: 1921-08-31
Abstract: 168,889. Akt.-Ges. Brown, Boveri, et Cie. Sept. 9, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Electromagnets; exciting.-The time required for exciting or de-exciting an electromagnet such as a motor field magnet, is reduced by the use of a twopart differentially - acting exciting apparatus such that the action of the part which opposes the change of excitation is, by means of an inductance, retarded respectively to the action of the other part which promotes the change of excitation. In the form shown in Fig. 1, the magnet e is excited by an apparatus comprising a generator c having opposing field windings a, b, the first of which is excited, through an adjustable resistance f, from mains g. The coil b is excited from the armature c through an adjustable inductance d, the effect of which is shown by the time-curve of current, Fig. 2, in the magnet e. With an initial current i1, a given reduction in the resistance f at time t, would, if coil a were used alone, give a current growth of final value i2 at time t4 of the form shown by curve I. Larger resistance changes would give curves as at IV, V, and VI. The effect of the coil b and inductance d with higher excitations is to cause an initial high rate of current growth, as at III, followed by a falling off as the inductance permits the volts generated by the coil b to oppose those due to coil a. Curves III and II show respectively the effect of making the time-constant of coil b greater than and equal to that of coil a. Curves I<1>, II<1>, III<1> show the corresponding curves of current decay. Two separate opposing armatures may be employed connected in series with the magnet e in place of a singlearmature differential machine. In this case, one armature is excited through a resistance from the mains, and it excites the fields of the armature through an inductance of selected timeconstant. The inductance d may be embodied in the field windings, and the winding b may alternatively be energized from an external source, means being provided for regulating the current in the winding b and inductance concurrent with the regulation of that in the coil a.

[Also in Group XL (c)] An oscillator loop, Fig. 1, is excited by two input voltages having the same frequency p and one of the voltages V1 1 modulates the output of .a first filter F1 and the other V1 is itself modulated by the output of the second filter F2 and the frequency delivered by F1 or F2 or both affects an indicator to show the phase angle between V1 and V11. In Fig. 2 with V1, V11 applied the F2 output AB at frequency q -¢ p. Fig. 1 modulates V1 in push-pull modulator M1 and the latter feeds into F1 which passes only the sum frequency q+¢p, Fig. 1, and this is modulated by VII in push-pull modulator M2 and the latter supplies F2 which passes only the difference frequency q - ¢p so that the loop oscillates between q+¢p and q - ¢p with q varying with the phase difference between the voltages V1 and V11. The frequency q+¢p or q - ¢p may be measured or as shown they may be mixed at 13, 14 to deliver the sum frequency 2q into frequency discriminator 15 whose output current actuates indicator 16. If frequency 2q occurs in the outputs of both F1, F2 a third filter F3, Fig. 3, may be utilized to pass 2q only to a phase indicator. The filters F1, F2 comprise amplifiers 4, 10 and thermistors may be included at 17, 18 to produce amplitude limitation.
