Patent GB-190023898-A (GB)
Title: Improvements in and relating to the Manufacture of Baskets.
Inventor: SCHLEICHER OSCAR
Filed: 1900-12-31
Granted: 1901-06-08
Abstract: 23,898. Schleicher, O. Dec. 31. Baskets.-The basket bottom, with the longitudinal sticks projecting upwards therefrom and temporarily strengthened by metal rods 7, if necessary, is placed upon a slowly-rotating disc 6, while the plaiting-material is passed through a tubular guide 10, which is reciprocated by a crank 13 so as to pass in and out between the sticks and rods 7. The material which is thus interlaced with the sticks is pressed downwards by a camoperated beater 17, which is mounted to slide on guides 25 and provided with a catch arrangement, whereby, as the sides of the basket increase in height, and the beater is raised on the guides, it is prevented from returning to a lower position. The guide-tube 10 is balanced by a counterweight 15, and may be automatically raised, as the interlacing proceeds, by a projection on the beater slide &c. The bottom is formed in a similar manner by clamping a number of radially-arranged sticks between a pair of discs on a rotating shaft, the guide-tube passing backwards and forwards between the sticks as the shaft revolves. When the basket bottom is finished, the extremities of the radial sticks are split, and the pointed ends of the sticks which are to form the framework of the body are inserted into the notches thus formed, and the sticks are then bent upwards, and the basket is completed as above described. A pair of washers are finally clamped one on each side of the central portion of the bottom. For making cylindrical baskets, the longitudinally-reciprocating guide 10 is dispensed with, the interlacing being effected always at the upper part of the basket, and, when a number of rows of interlacing material have been inserted, they are pressed down towards the bottom by a disc having radial ribs or teeth. For making square baskets, the bottom is mounted on a support which is moved by hand or other suitable means in a straight line until an angle is reached, when it is rotated through a right-angle, and the adjacent side proceeded with as before.

Title: A New or Improved Machine for use in the Cleaning of Gum and other Confectionery.
Inventor: WOLSTENHOLME JOHN
Filed: 1903-05-09
Granted: 1903-11-19
Abstract: 10,562. Wolstenholme, J. May 9. Sifting confectionery.- Fig. 1 shows a side elevation, and Fig. 3 a transverse section, of a machine for cleaning and detaching the loose starch from gums and other confectionery after being baked in starch moulds. The gums are first agitated in an inclined tray H mounted over a rectangular casing A, and then pass by a shoot D into an inclined cylindrical chamber B, situated within the casing A and containing a rotary brush C. The tray H has a sieve -like bottom, and projecting studs N at its upper and wider end fit in slots in uprights 0, while its lower end rests on the casing A, which is cut away so as to form a guide for the tray. The tray is agitated by a cam L on a shaft M, bearing against a roller K on a stud J carried by the bracket I. Spiral springs P are attached at one end to the studs 0, and at the other end to the casing. The upper part of the chamber B is made of wood and provided with bristles, while the lower part is composed of woven wire. The bristles on the brush C are arranged in spirals, and may be shorter at one end of the brush than at the other, or the roller on which they are mounted may be tapered. The shaft M is driven by a belt from a shaft R, and the brush C and shaft R are driven through bevel gearing from the driving-shaft U. The starch falling through the tray H is received in a tray X, which is inserted through an opening Z in the side of the casing A and is supported on cross-stays Y. The starch falling through the bottom of the chamber B accumulates at the bottom of the casing, or it may be received in a drawer A<x>, whence it is removed for re-use. The polished gums after passing through the chamber B are delivered by a shoot F. The plate E fitted in the side of the casing opposite the end of the chamber B and supporting the axle of the brush is removable, so that the brush can be withdrawn when desired. To deaden the noise, the roller K may have a rubber tyre, or the studs N may be fitted with rubber sleeves, or a fixed cushion below each stud may be employed. Two chambers B may be fitted in one casing, and the top of the casing and tray H may be enclosed by a cover, with a hopper to admit the gums. According to the Provisional Specification, the trays X may be fed through the machine on an endless band, and, as they are withdrawn from the machine, they may pass beneath rollers or scrapers which flatten and smooth the starch.
Patent GB-190310698-A (GB)
Title: Improvements relating to the Phase Synchronisation in Electromotors with Alternating Field.
Inventor: ZIEGENBERG RUDOLF
Filed: 1903-05-11
Granted: 1904-05-11
Abstract: 10,698. Ziegenberg, R. May 11. Motors, controlling.-Relates to phase synchronization in alternating-current motors having their field magnets excited by alternating current at the full rate of periodicity. The magnetomotive force for exciting the field is obtained in some way from the mains, and the field and load current should be in phase, or at such an angle as to neutralize the phase difference. Fig. 1 is a diagram illustrating the angles of phase in a series-wound motor. J represents the current, there being an angle # between it and the electromotive force E, Es is the electromotive force due to self-induction, and Eg the back electromotive force, the lag due to hysteresis being neglected. An improved electromotive force Er is required to overcome this back electromotive force. Fig. 3 is a diagram of a separately-excited motor in which the current J is in phase with the electromotive force E. In this case a counter-electromotive force E<1>s is necessary to compensate for the electromotive force Es. The back electromotive force Eg<1> with this gives a resultant Eg which is compensated for by providing an exciting- current Jm<1>. The exciting-current may be produced by means of a rotary converter S W, as shown in Fig. 7, in which S is a synchronous motor and W a synchronous generator, the motor being adjusted so that cos #=1. In this arrangement, the load on the motor S being small, there is but little reaction on the armature circuit, though the phase difference in the field F may be great, being adjusted to meet the conditions indicated in the diagram. To maintain the phase relationship with the varying load, the field coil F consists of a number of sections connected to contacts. Arranged in suitable relation is a series of choking-coils D, so that, as sections of the coils F are cut out by a regulator R, they are replaced by equivalent inductive resistances D. The regulator may be operated automatically or by hand. Another method of obtaining an exciting-current having a suitable angle of lead is to provide auxiliary brushes. Fig. 5 shows one arrangement, the brush III being fitted in a recess in one of the pole-pieces. Fig. 6 shows another arrangement, in which an additional field winding f n in inductive or parallel relation with the main field f r is provided.
