Patent GB-190517843-A (GB)
Title: Improvements in and relating to Electric Motors especially intended for Hoisting and similar purposes and in Systems of Control therefor.
Filed: 1905-09-04
Granted: 1906-10-04
Abstract: 17,843. British Thomson-Houston Co., [Ceneral Electric Co.]. Sept. 4. Field magnets ; motors, controlling.-A compound-wound motor for operating ammunition and other hoists and elevators &c. has two series field windings which aid one another when the motor is raising loads and when lowering light loads, the motor acting as a generator and serving as a brake when overhauled by heavy loads, the aggregate effect of the two series windings in all cases being cumulative to that of the shunt winding. The shunt field winding B of the motor M is connected directly across the supply mains through the switch S. In the 'off ' position of the controller, the armature A and series field coil D are short-circuited by the auxiliary contacts k, k<1> engaging the fixed contacts 8, 9. To raise the load, the switch S is closed and the controller contacts F brought into engagement with the fixed contacts 1 ... 7. The motor is thus connected to the line with a portion of the resistance R in circuit with the armature and series coils, Fig. 2, and further movement of the controller cuts out more resistance R, until the motor is connected directly across the line, Fig. 3. Upon return of the controller to the 'off' position, the armature is again short-circuited, the motor acting as a brake to bring the load to rest. To lower the load, whether light or heavy, the controller is turned in the opposite direction, to bring the first of the contacts G into engagement with the fixed contacts. In this position, the motor armature and series coil D are short-circuited, while the series coil C is connected across the line in series with the resistance R, the continued movement of the controller connecting the armature and coil D across increasing amounts of resistance, Figs. 7 to 9. If the load is light and power is required to make it descend, current flows from the mains to the fields and through the armature, as shown in Figs. 7 to 9, in a direction opposite to the direction when the load was being raised, the current supplied increasing with each movement. The series field coils are then in opposition, the resultant field, due to the coil C through which the greater current passes, augmenting the shunt field. If the load is heavy and the motor is subsequently overhauled, it acts as a generator, the directions of the current being shown in Figs. 4 to 6. The maximum braking effect is shown in Fig. 4, in which the current generated produces an excitation in the coil D which assists the coils B, C. As the controller is moved, the field is weakened, and the speed of the motor increased. In the final position, the motor may be sending current back into the line, the two series field coils being opposed, and the winding D being predominant. The shunt field winding may be connected to the opposite end of the series winding from that shown.

Title: Improvements in "Chocolate Presses"
Inventor: CARLSON GABRIEL
Filed: 1906-12-12
Granted: 1907-06-27
Abstract: 28,364. Carlson, G. Dec. 12. Presses. - Chocolate is dried in a piston press, the liquid or viscous substance being supplied by pumping on either side of the piston alternately and worked slowly towards the ends where it forms solid dry cakes, the compression of the substance causing moisture to exude at the sides and into the piston. Heads bare bolted to the opposite ends of the cylinder so that a restricted passageway c is formed. The piston is composed of two parts e, which are perforated at h and secured together on the pistonrod so as to leave a hollow opening. The two castings e are covered with felt, over which is a perforated steel or other plate j. A tube k passes through and is secured to the lower part ot the piston, and this tube is perforated so as to receive moisture from the piston interior, and remove it. The other end of the tube passes through a stuffing-box in one of the cylinder heads. The cylinder is lined for part of its length with perforated sheet steel or other material backed by strips r of felt below, which are moisture channels s communicating with a bottom channel t which opens into an outlet u. The inner faces of the cylinder heads, which are shaped as shown, are lined with sheet metal and felt as the interior of the cylinder is, and the heads have moisture outlets 2. Longitudinal passage-ways 3, 4 are formed in the pistonrod communicating by outlets 5, 6 with the spaces on the sides of the piston. The material is fed from a hopper 19 by a pump 7 through a flexible tube 8 and a rotary valve 9 to these passages. An arm 10, Fig. 3, is secured to this valve, and is threaded over a rod 12 secured to one of the cylinder heads. An extension piece 13 is secured to the arm 10 and, when the arm 10 is shifted by the action of one of two spring abutments 11 on the rod 12, this piece engages one of the notches 14 in a spring plate and holds the valve locked, so as to direct the material through one of the passages 3, 4. The piston is thus slowly moved in one direction till the motion of its rod brings the valve-rod against a projection 11 and reverses the valve. The dry material escapes slowly through the passages c. The pump used may be doubleacting.
