Title: An improvement in or relating to certain dyeing or like machines
IPC: D06B5/00
Filed: 1921-10-27
Abstract: 189,953. Haigh, F. Oct. 27, 1921. Agitating materials and liquids together. - In machines for dyeing and otherwise treating garments &c. with liquids in which the liquid is agitated by a paddle-wheel having its blades dipping into the liquid, a pivoted plate is so associated with the paddle-wheel that if a garment is carried up out of the liquid, it acts to stop the paddlewheel and, in some cases, to complete the circuit of an electric bell. The paddle-wheel b is mounted on a shaft b<1> on the vat a and its blades normally pass between side extensions e<1> of the plate e which is pivoted on a spindle d. When a garment is carried up out of the liquid by a paddle, the spindle d is turned and acts through a lever f, link o, and angle lever h to withdraw a spring-controlled locking-pin i from a sliding spring-controlled bar k carrying a clutch fork m. The clutch n is thereby moved to. the left so that the driving-pulley q runs loosely on its shaft, and a part n<2> of the clutch engages a fixed brake part w to bring the parts quickly to rest. To restart the machine, a lever s is operated to move the bar k to the right against the spring t, the bar being then retained by the locking-pin i.

Patent GB-811705-A (GB)
Title: Improvements in protection relay arrangements for polyphase motors
Inventor: ROSS THOMAS WYLIE
IPC: H02H3/34
Filed: 1954-10-07
Abstract: 811,705. Protective cut-out arrangements. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Oct. 7, 1955 [Oct. 7, 1954], No. 28935/54. Class 38 (5). In a protective arrangement for a polyphase motor, two of the supply lines are associated with relays of the induction type, each relay having an electromagnet 5R or 5B energized from the associated line and a further electromagnet 6R or 6B energized from a secondary winding 37R or 38B of an auxiliary transformer 36R or 36B which has one primary winding 39R or 39B connected to a secondary winding 40R or 40B of the electromagnet 5R or 5B, and another primary winding 35B or 35Y energized from another of the lines. Such an arrangement enables the motor to be tripped out at a lower value of line current when one line conductor is interrupted than when the motor is operating under balanced conditions. Each relay has a disc 1, Fig. 1, rotatable between the electromagnets (not shown in Fig. 1) and damped by a permanent magnet 7. The windings 31R, 31B on the electromagnets 5R, 5B are energized from current transformers 28R, 28B in series with the windings 32R of instantaneous over-current relays 29, 30. The relay 30 also has an earth fault coil 34 connected between the star points of the current transformers and the relay windings. Under normal conditions, the coils 31R, 31B of the upper magnets 5R, 5B of the induction relays are energized in accordance with the associated line current and as the voltages induced in the windings 40R, 40B lag in quadrature on these line currents the resultant energization of the windings 38R, 38B of the lower magnets from the transformers 36R, 36B will be the vector difference of a component in quadrature with the associated line current and a component lagging the associated line current by 120 degrees and derived from the adjacent line current. Should one of the conductors B, Y, R be interrupted, one of the relays will be energized only in accordance with the associated line current, the winding 35B or 35Y not being energized, so that the torque of the relay is increased. When this relay closes its contacts 17, 20, a tripping relay 52 is energized from an auxiliary supply 44, 45 and closes contacts 49, 50 to energize the trip coil 43 of a circuitbreaker (not shown) and at contacts 50, 55 completes a holding circuit for itself. The relay 52 reopens when it is short circuited by the closure of contacts 16, 17 of the induction relay. The current setting of each induction relay is effected by adjusting a control spring 8 by means of an adjusting disc 10 with spring anchor 9 and friction clamping means 13. The time of operation of each induction relay is adjusted by altering the position of the back contact 16 by means of a further adjusting disc 14.
