Title: Improvements in dough dividing machines
IPC: A21C5/04
Filed: 1923-07-27
Abstract: 218,855. Embrey, L. July 27, 1923. Cylinder machines; feeding and measuring; delivery.-In a dough-dividing machine in which a carrier provided with one or more measuring cylinders equipped with pistons is rotated to bring the cylinder from the filling to the discharge position, the depression of the pistons during the filling operation tips a scale beam and thus releases mechanism which rotates the carrier, inverts the cylinders, and discharges the dough. The machine comprises a hopper 14, feed rollers 10, 11 mounted in trunnions 12, 13 and a carrier mounted in hollow trunnions 6, the trunnions 6, 12, 13, being supported on the sideplates 8 of the frame. The carrier contains a cylinder 2, Fig. 9, in which slide pistons 3 limited in movement by pins on the cylinder sliding in grooves 5. The parts of the machine are driven from a pulley 25 which normally rotates freely on a shaft 16 and is alternately clutched with the cylinder-rotating mechanism and the feed mechanism. The pressure of the dough on the piston 3 depresses a cross-rod 36 passing through the hollow trunnions 6 and adjustably supported on two arms 33 resting on knife edges 34 at one end of a double scale beam 30. The depression of the rod tips the scale beam and allows a pawl 22 held in the raised position by a pin 37 on the beam to fall and engage a tooth 24 on the pulley 25, thus rotating the carrier through the pawl 22, an arm 21, a sleeve 20 and gear wheels 17. 18. After one revolution, the pulley is de-clutched by the pawl 22 striking a tappet 38 on the arm 39. The pulley is then engaged with the shaft 12, in order to drive the feed rollers 10, 11 through gear wheels 15, by a cam surface 41 riding over a fixed cam 40 so as to move the pinion 18 and pulley 25 axially along the shaft 16 and cause engagement of the jawclutch members 26, 27. The scale beam is fulcrumed on knife edges 31, and is provided with a buffer spring 47 and scale pan 32 for determining the weight of the pieces of dough. The latter is discharged from the cylinder by contact of the pistons against a stationary bar or, alternatively, a cam 55, Fig. 9, and scapers are provided for' cleaning the feed rollers and the carrier. Modifications are described in which the time of discharge of the dough may be altered, in which shutters 62, Fig. 9, are fitted to the sides of the carrier to vary the supply of dough, and in which trip mechanism comprising toggle levers is employed.

[Also in Group II] In a semi-conductor amplifier having two closely spaced electrodes in contact with the semi-conductor surface, one of the electrodes has a contact surface of gold, and the associated region of the semi-conductor also contains gold injected into its surface layer. In Fig. 1, a block of N-type semi-conducting material 1 is supported by a metal base electrode 2, and the surface is in contact with a fine chiselshaped piece of gold wire 4 forming the emit. ter electrode, and a similar shaped piece of phosphor-bronze wire 5 forming the collector electrode. The collector electrode may consist of other suitable soft metal containing a donor type of impurity. Electrodes 4 and 5 may be separated by a thin piece of insulating material such as mica. Alternatively, goldplated tungsten or copper wire could be used for the emitter. An electro-forming treatment may be applied in which a current is passed between the emitter and collector electrodes in such direction as to convey some of the gold from the emitter into the surface of the semi-conductor, and afterwards a current is passed between these electrodes in the direction corresponding to high resistance at the collector electrode. A cathode-ray tube and resistance and switch arrangement in conjunction with a saw-tooth generator as described in Specification 681,809 may be used for applying the electro-forming current and for observing the effect. The emitter and collector electrodes may be on the opposite sides of a thin disc of semi-conductor material The invention enables the collector and emitter electrodes to be spaced two to four hundredths of an inch apart instead of approximately two thousandths as is usual, and also reduces the feed-back from the collector to the emitter electrode.
