Title: Improvements in electromagnetic brakes and clutches
IPC: F16D48/06
Filed: 1946-03-09
Abstract: 609,264. Electromagnetic clutches. WINTHER, A. March 9, 1946, No. 7428. Convention date, Jan. 27, 1945. [Class 80 (ii)] [Also in Group XXXIV] To provide a current of short duration sufficient to move the armature and magnet of an electromagnetic brake or clutch into initial frictional engagement, a condenser is arranged in parallel with the regulating resistance and is connected in the magnet circuit prior to reducing the resistance for increasing the pressure between the armature and magnet. Fig. 2 shows a brake comprising a magnet ring 3 of channel-section to contain the coil 1 and secured to a disc 5 bolted to a stationary frame 7. The ring 3 is closed by a friction ring 25. The armature disc 19 is slidable on pins 17 on a spider 15 keyed to the shaft 11 to be braked and is normally held spaced from the magnet by weak springs 23. A clutch of similar construction is also shown the armature disc and the magnet being mounted on coaxial shafts and the current being conducted to the coil by slip rings. A cooling fan is carried by the armature shaft. The circuit of the coil 1 includes a rheostat 39 comprising a series of leaf-springs 35 carrying contacts 37 that are normally spaced from each other and are controlled by a swinging arm 41. A condenser 43 is connected in parallel with the rheostat. To apply the brake, the master switch 31 is closed and the arm 41 is moved to engage the first two contacts with each other to apply the voltage of the battery 29 across the total resistance. The condenser is thus charged and causes an instantaneous rush of current through the coil 1 moving the armature 19 into contact with the magnet. When the condenser current has died out, the current that flows through the coil and the total resistance is sufficient to hold the armature in light contact. The resistance may then be progressively reduced to increase the pressure between the armature and the magnet by further movement of the arm 41 to close the contacts 37 successively. The condenser also acts to reduce arcing at the several contacts when these are disengaged.

Title: Improvements in or relating to a weld nut and method of producing the same
IPC: B21K1/70
Filed: 1962-02-27
Abstract: 926,144. Making weld nuts; forging. LAMSON & SESSIONS CO. Feb. 27, 1962 [March 6, 1961], No. 7622/62. Classes 83 (2) and 83 (4). [Also in Group XXV] A method of making weld nuts from bar stock comprises advancing the stock, indenting pairs of opposed recesses at spaced intervals along the side of the stock by applying a squeezing pressure, the upwardly disposed metal of the recesses forming bosses projecting above the top surface of the stock, cutting the nut bodies from the lead end of the stock and parting the bosses by such cutting so that portions of the boss remain on the severed nut bodies as welding projections. Flat metal stock 26 is fed by a pair of feed rolls 49 along a guideway 47 of a base 46 in the direction 48. A pair of reciprocating die members 50, 51 each having an indenting portion 60 are mounted in transverse inclined guideways 52, 53 positioned on each side of the guideway 47 and produce inclined concave indentations in the substantially upper portion of the stock faces 30, 31 and raised bosses 35 projecting above the top face 27.

Abstract: 287,524. British Thomson-Houston Co., Ltd., (Assignees of Rowell, R. M.). March 23, 1927, [Convention date]. Addition to 286, 691. Tell-tale apparatus.-Relates to a system of the type described in the parent Specification wherein the average reading or the sum or difference of the readings of two or more indicating devices, such as watt meters, is indicated on a single receiver. As shown in Fig. 2, the indicating instruments control transmitters A, B comprising rotor windings 18 supplied from alternating current mains 19 and co-operating with threephase stator windings 17. Secondary windings 22 of transformers 20 are connected in series with the transmitter B and the stator phases 24 of a receiver C, and the primary windings 21 are starconnected and supplied by the transmitter A. 'The voltages applied to the receiver windings as a result of the voltages induced in the secondary windings 22 and the transmitter B produce a resultant field, the direction of which corresponds to the mean position of the transmitters. A pointer, carried by a. permanent bar-magnet or a single-phase rotor adapted to set itself along the axis of the resultant field, co-operates with a scale calibrated to indicate the sum or difference of the readings of the individual indicating devices. Additional transmitters may be connected to 'transformers, the secondary windings of which are connected in series with the windings 22, 24. In the modification shown in Fig. 4. the transformers are omitted and corresponding phases of the transmitters and the receiver are connected in series. In order to prevent reaction of the transformers upon the transmitters and thus guard against the tendency of the transmitters to occupy false positions, the torque of the indicating devices controlling the transmiters is made large compared to the torque of the transmitters. The transmitter torques may be reduced and correctly adjusted by resistances 28.

Title: Improvements relating to the weighing of a load carried by a crane or the like
Inventor: FIELDER ERIC CHARLES WILLIAM
IPC: G01G19/18
Filed: 1962-03-01
Abstract: 970,280. Weighing electrically. E. K. COLE Ltd. March 1, 1963 [March 1, 1962], No. 7946/62. Heading G1N. Apparatus for weighing a load, whilst being lifted by a crane or the like, comprises a load cell producing a signal indicative of the force exerted by the moving load, means for deriving a signal which is a function of the acceleration of the load, and means for combining the two signals to give an indication of the mass of the load. The output from load cell 1 is amplified, rectified and applied to potentiometer VR1. The output from a tachogenerator 5, responsive to the speed of the hoist rope, is differentiated and applied to a servo loop including potentiometer VR2, whose slider is connected to that of VR1, so that the position of each slider represents the acceleration of the load or a function thereof. The output from the slider of VR1 represents the mass of the load and after passing through gate 8 this signal is averaged by Miller integrator 9 and potentiometer VR3. The amplified output from load cell 1 operates a trigger circuit 4 when the signal exceeds a predetermined value, to open gate 8 after a one second delay. The acceleration signal from network 6 is amplified and differentiated at 17, 18 and the output operates a trigger circuit 19 to close gate 8 and block the output if the acceleration is changing so fast that the servo loop cannot respond correctly. The output from trigger circuit 4 passes, after a one second delay, through a gate 12 to engage a clutch 14 and disengage a brake 15 on the shaft of a synchronous motor 16, causing the slider of potentiometer VR3 to move at a constant speed. The output of integrator 9 is therefore divided by time and represents the average mass of the load. In addition to closing gate 8, excessive changes of acceleration close gate 12 to lock the slider of VR3. When a weighing cycle is complete a button 20 is operated to open gate 10 and connect the output from VR3 to printer 11, and after a delay to close gate 22 which disengages both clutch 14 and brake 15 to allow VR3 to return to zero under the action of a spring. Integrator 9 is also reset. A similar sequence of operations follows if the slider of VR3 reaches a limit switch 23. To ensure a correct reading when the load is stationary potentiometer VR1 may divide by (1 + acceleration), where acceleration is expressed as a multiple of g. Potentiometers VR1, VR3 may be replaced by solid state devices, and a tachogenerator included in servo 7 could replace networks 17 and 18.
