Title: Motor overtemperature/overload protective system
IPC: H02K11/25
Filed: 1973-10-11
Abstract: 1450567 Electric motor protective systems CANADIAN GENERAL ELECTRIC CO Ltd 11 Oct 1973 [12 Jan 1973] 47578/73 Heading H2K A protective arrangement connected to an electric motor has both an analogue circuit 14 simulating the thermal characteristic of the conductors of the motor and a temperature detecting means 16 in heat transfer relation with the motor windings and providing voltage signals to detector circuits 35, 36. Resistance 15 represents the thermal resistance of the insulation between the windings and detector means 16 and the capacitor circuit 14 is charged before switching on through the resistor 15 to an extent dependent on the motor temperature detected at 16. On switching on if the motor is stalled the capacitor voltage rises sharply and after reduction in a voltage divider 3, allowing for the higher thermal rating on inrush current, the detectors 35, 36 are operable through a diode 33. Continuous overload is detected by the combined effect of the charging current through 15 and the output of the measuring circuit through a diode 40. The charging current is provided by current transformers 44, 45, 46 feeding step-up transformers 47, 48, 49 producing voltages rectified at 50, 51, 52, across a capacitor 54 providing an amplifier 57 with a voltage proportional to the line currents. The amplifier 57 controls a transistor 59 in circuit with a Zener diode 62 and a variable resistor 64 and provides for a two slope characteristic (Fig. 5, not shown) relating the motor current and charging current.
Patent GB-476343-A (GB)
Abstract: 476,343. Shoots. INTERNATIONAL COMBUSTION, Ltd., and DAVIDSON, G. W. June 12, 1936, No. 16435. [Class 78 (i)] A hopper or shoot 1 is provided with an anti-breakage door 4 adapted to close the inlet of the hopper and to be moved bodily along the. hopper by a transmission device driven by mechanism which effects the movement of a charged container 2 to discharge the latter into the hopper, the door being displaced near the hopper outlet to permit discharge of the material therefrom, and the return of the door to the inlet being effected by counterweights which reverse the motion of the transmission device upon disengagement of a clutch between the device and the mechanism. In the construction shown the hopper 1 is filled from a wagon tippler 2. The hopper door 4 has rollers 5 running in guides 6 on the hopper and is raised and lowered by ropes wound on drums 7 on a shaft 8 adapted to be driven through a clutch 9 from the driving mechanism of the tippler, so that as the tippler is rotated to discharge a wagon the door 4 is moved a predetermined distance down the hopper,. and this is repeated each time a wagon is discharged until the hopper is full. The hopper discharges through a door 14 into a pivoted loader 3 controlled by a skip 13. When the skip leaves the pit bottom the loader 3 may be brought automatically in known manner to a position in which it closes the discharge door 14. Alternatively the door 14 may be operated by hand. In either case, when the loader rotates from the skip-charging position to the position shown in full lines, in which it receives material from the hopper, a projection 15 on the loader rocks a lever 16 and thereby disengages the clutch 9 through linkage 17, 18, 19 and a weighted lever 20. When the shaft 8 is thus disengaged from the tippler mechanism the door 4 is raised to the hopper inlet by means of a counterweight 12 acting through a rope 11 and drum 10 on the shaft 8 controlling the door. As the counterweight descends it finally strikes an arm 22 on the shaft of the lever 20 and causes the clutch 9 to be re-engaged. The hopper at the top and the upper side of the door 4 may be provided with rubber pads to avoid breakage of the material dealt with. The hopper may be at the mine surface, being located between a skip and a conveyer. The clutch may be controlled electrically. According to the Provisional Specification the door plate 4 may be driven by a separate motor and may be controlled by a dash-pot.

Abstract: 1,130,223. Associative stores. WESTERN ELECTRIC CO. Inc. 18 Nov., 1965 [24 Nov., 1964], No. 48986/65. Heading G4C. [Also in Division H3] An associative memory for use as a store for telephone directory information comprises a plurality of bits each bit including four magnetic anisotropic thin films 80, Fig. 1 (not shown), arranged in a co-ordinate array and providing non-destructive read out, see Division H3. In operation all the corresponding bits of each of the word lines w 1  to w n  are written simultaneously by energizing sample " 0 " and write circuit 88 and sample " 1 " and write circuit 90 to supply a positive and negative pulse respectively to conductors 82 and 82<SP>1</SP> of the chosen bit line position b 1  to b n  through gates 85 controlled by sample and write logic circuits 86. Simultaneously wmite-read pulse source 93 is energized by timing control circuit 101 and write-read logic circuit 99 to apply tipping pulses to conductors 83 of each of the word lines, the tipping pulse being positive for a " 1 " and negative for a " 0 " being stored. Sampling.-In order to sample the store all the word lines are simultaneously sampled by applying a positive pulse to conductor 11 of each bit line for sampling a " 0 " and a negative pulse to conductor 11<SP>1</SP> of each bit line for sampling a " 1 " from sources 88, 90. The resulting rotations of the magnetizations of the thin films for each pair of films along the bit lines for a particular bit position are induce voltages in the corresponding pair of word conductors 83, 83<SP>1</SP> which are summed by summing circuits 91 1 -91 n . Cancelling outputs in the summing circuits signifying a match between the bit being searched for and the content of the bit position being searched. Additive signals indicate a mismatch. The output signal conditions of summing circuits 92 are transmitted to respective negation circuits 95 of which only that one is energized corresponding to the word line which produces no output signal in its summing circuit, i.e. a match with the word or part of a word being looked for. The output from this negation circuit is transmitted via encoder 96 to address memory 98 for temporary storage which is later read out under the control of timing circuit 101 to transmit its address contents to the writeread logic circuit 99. This circuit selects the particular word line to be selected for read out. Read-out.-The write-read pulse source 93 of the selected word line w 1  to W n  determined by write-read logic circuit 99 is energized to apply a negative read current pulse to the conductor 83 of the associated word line. This causes magnetization rotations of the coupled film pairs of the bit addresses in this word line. If the signal induced in conductor 82 is negligible a " 0 " is stored whereas if a significant signal is induced a " 1 " is stored. The signals representative of the information stored in the word line are transmitted to information utilizing circuits 91.

Abstract: 987,036. Vehicle steering gear; wedges. FORD MOTOR CO. Ltd. Dec. 18, 1963 [Dec. 20, 1962], No. 49942/63. Headings F2K and F2Q. In a vehicle steering mechanism comprising an input shaft 12 with a screw portion carrying a ball bearing nut 15, along one side of which is formed a rack 16 meshing with a sector 20 mounted on an output shaft 21, the shaft 21 has limited axial movement to alter the backlash between the rack 16 and sector 20, and a spring loaded wedge 45 in an inclined bore 46 extending transversely in the shaft 21 urges the shaft axially to take up backlash due to wear. A stud 35 fixed to the cover 36 of the gear housing 11 extends into a bore 37 in the shaft 21 and coaxial therewith, with a head 44 bearing in a T-section inclined slot extending the length of the cylindrical wedge 45, a com pression spring 52 acting on the end of the wedge. When full travel of the wedge has been reached, the wedge is drawn back manually and the stud 35 screwed down to reset the wedge for further automatic backlash compensation. The roots 27 and tops 28 of the rack teeth lie in non-parallel planes both canted with respect to the longitudinal axis of the shaft 21, while the roots 30 and tops 32 of the sector teeth lie on conical surfaces. Alternative tooth forms giving a change of backlash with axial movement of shaft 21 may be used. The sector teeth 31 are shaped so that backlash is a minimum when the steering gear is in the straight ahead position and increases on either side of this position to diminish the required steering wheel torque for improved manoeuvring. This is achieved by giving the centre tooth 33 of the sector a greater circular pitch than the other teeth or by setting the sector pitch circle eccentrically relative to the axis of shaft 21.
