Title: Improvements in or relating to the operation of direct current motors over desired speed ranges
IPC: H02P7/292
Filed: 1944-02-18
Abstract: 636,732. Automatic control systems for electric motors. STEVENS, A. H. (Submarine Signal Co.). Feb. 18, 1944, No. 3061. [Class 38 (iv)] [Also in Group XXXVII] Speed and torque.-The speed and torque of a direct current motor are controlled by means of a grid-controlled gaseous rectifier valve which is operated from an auxiliary alternating current source and is controlled by biasses influenced by the speed and load of the motor so that the valve periodically shunts an impedance in the motor armature circuit. A gas-filled triode rectifying valve 3 is controlled through a circuit, as described in Specification 636,661, comprising a twin triode valve, and is connected in shunt with a resistor 20 which is connected in series with a motor armature 1. A resistor 14 shunting the motor provides a positive bias, which is opposed to a negative bias derived from a resistor 17 connected in series with it and applied to the grid of a triode section 7 of the twin triode control valve. Rectified current is supplied to the resistor 17 by means of a rectifier 19 which may be of the full-wave type. Increase of motor speed increases the positive bias in a portion 14<1> of the resistor 14, to increase the negative bias on the resistor 13 as applied to the grid 6 of the valve 3 thereby reducing the current supplied to the motor, and its speed. By appropriate choice of the settings of the potentiometers 14 and 17 the motors may be given a level or rising speed-torque characteristic. When the motor is operated with a rising characteristic the gaseous control valve 3 is operated with the valve not fully opened for a point corresponding to normal full load and full speed conditions. Potentiometer 17 is the primary means for setting the motor speed, any deviation from the desired speed causing a variation in one sense or the other of the opposition voltage from the potentiometer 14 to advance or retard the point of conduction of the valve 3.

Title: Improvements in or relating to machines for performing a pressing operation upon thebottoms of boots and shoes
IPC: A43D35/00
Filed: 1926-01-09
Abstract: 269,114. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Jan. 9, 1926. Levelling.-Relates to machines of the kind in which there is, between a shoe-supporting jack and a levelling tool, a relative bodily traversing movement longitudinally of a shoe bottom to be levelled; and consists in (a) a single controlling means for a plurality of jacking instrumenalities, and (b) means, operatively connected with a pressure mechanism, adjustable at the will of the operator to vary a predetermined cycle of pressure applying capacity. The shoe is jacked, i.e., clamped or held in operating position, by a last pin which can be tipped to force the toe down on to a toe rest, and also by a leather saddle 22. The saddle 22 is connected by springs 24, 26 with a manual operating lever 28. The last pin is tipped by a link 50, provided at its lower end with a slot to engage a pin 52 carried by duplicate levers 44 also actuated by the handle 28. A latch 64 is turned to the position shown when it is desired that the handle 28 shall operate the last pin. When the saddle 22 is not to be used it may be draped over the handle 28. Thus, this handle operates either or both of the jacking instrumentalities, at the will of the operator. The levelling roll 72 is depressed by a spring 124 with a superposed plunger engaging a lever 134 linked to an actuator 140 normally operated by a cam roll 144. This roll co-operates with a cam 146 formed with depressions for relieving the pressure at various parts of the cycle. Adjacent to this cam is a second cam 170 with only one depression, this corresponding to the end of one cycle and beginning of the next, when the roll is passing off or on to the toe end of the shoe. The actuator 140 carries a latch 182, which in one position abuts against an actuator 176 carrying a cam roll 174 co-operating with the cam 170. Adjustment of the latch, therefore, determines whether the pressure cycle predetermined by the cam 146 shan be performed, or whether all intermediate pressure reliefs shall be cut out. Sipecifications 20197/99, 17939/09, 103,849, 236,270, 261,810 and 268,886 are referred to.

Abstract: 425,791. Moulding dough by rolling- machimes. PETERS, J. P., 8, Noordsingel, Rotterdam, Holland. Feb. 2, 1934, No. 3442. Convention date, June 7, 1933. [Class 87 (ii)] In order to elongate a roll of dough, the roll, while rotating, is conveyed parallel to itself, and is brought intc contact with a counterpressure roller, which roller endeavours tc oppose the rotation of the roll and is moved forward in the same direction as the roll and parallel thereto. The dough roll is carried by a conveyer 1, Figs. 1 and 3, beneath a rolling-board 9 and into contact with a roller 10 rotated through sprocket wheels 28 and chains 29. The journals 12 of the roller 10 engage in guides 11 and are embraced by the ends 13 of arms 14 attached to a shaft 15. The shaft 15 carries an arm 16 provided with a pawl 17 adapted to engage a ratchet wheel 20 freely mounted on the shaft 15. The wheel 20 is attached to a pulley 21 over which passes a rope 22 carrying a weight 23, the pulley being provided with a nose 26 adapted normally to engage a fixed stop 27. The arms 14 and roller 10 are partly counterbalanced by a weight 25 on an arm 24 on the shaft 15. As the dough roll is carried forward by the conveyer, it pushes back the roller 10, the pressure of which is controlled by the weight 23, until the pawl 17 is tripped by the engagement of its tail 18 with a fixed abutment 30, thus freeing the roller 10 from the weight 23, whereupon the roll lifts, and passes beneath, the roller. The roll then passes to a second elongating device 7, Fig. 1, and is finally delivered below a guiding board 8. The rolling boards 9 may be of wood covered with canvas, and the rollers 10 may consist of light tubes ; the roller of the first elongating apparatus may be covered with canvas. The roll of dough may be formed by passing a sheet of dough beneath a roller 2, a curling flap 3, and a series of tubes 4, and rods 5, which are freely mounted in inclined slots.
