Title: Temperature responsive control arrangements
IPC: H02H7/085
Filed: 1964-09-07
Abstract: 1,061,600. Protective arrangements. MOTOROLA Inc. Sept. 7, 1964 [Sept. 16, 1963], No. 36542/64. Heading H2K. A control or protective circuit comprises a static switching device 30 connected between an, A.C. source L1, L2 and a load, two transformers supplying potentials of opposite polarity and a temperature-responsive resistance element to vary the potential from one. of the transformers to determine the conductive or non-conductive condition of the device 30. The load may be the operating coil of a contactor controlling a motor having positive temperature coefficient resistors associated with its windings. As shown, the device 30 comprises a rectifier bridge 34, 36, 38, 40 with a silicon-controlled rectifier 32 which, when conductive, permits alternating current to flow from the source to the load. A negative bias for the gate of the rectifier is derived from transformer 42, diodes 44, 46 and a resistor 23. A positive bias for the gate is derived from a transformer 50, diodes 52, 54 and a resistor R 1 , the transformer 50 having a primary winding 50a supplied from a secondary winding 42b of the transformer 42 through thermistors connected to terminals X 1 , X 2 . A. further primary winding 50b of the transformer is energized when the device 30 is conducting. Under normal conditions the positive bias exceeds the negative bias and the switching device 30 is conductive, but should, e.g., the motor overheat, then the increase in resistance of the thermistors reduces the positive bias. allowing the gate of the rectifier 32 to go negative. The rectifier 32 ceases to conduct to interrupt the supply to . the load and to the primary winding 50b so that a substantial fall in the temperature of the motor is necessary before the supply can be restored. By changing the polarity of the diodes 44, 46, 52, 54, negative temperature coefficient resistors may be used as the sensing elements. Two oppositely connected silicon controlled rectifiers may be used instead of the device 30.

Current values of the image dimensions are measured on at least one line of the camera raster, and compared with the reference values. As shown in Fig. 1, a projection and filter system 2, 3 forms an image of an object at a TV camera 1. The video signal is clipped by a limiting amplifier 4 and fed to a logic unit 5 which also receives inputs from a circuit 6 selecting a line of the scanning raster, and a circuit 8 which defines an electronic aperture in which measurements are made. The unit 5 includes means for comparing actual and reference values of image parameters expressed as numbers of pulses. Operation of the system is started by a pulse oscillator 9 which drives a servo-mechanism 7 causing relative movement of the object and the camera 1. When an image dimension exceeds a reference value, a signal is produced, the image is transferred to a measuring arrangement, and the oscillator 9 initiates the search for another image of the required type.

Title: Notation conversion machine
IPC: G11C11/30
Filed: 1955-12-22
Abstract: 817,837. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1955 [Dec. 31, 1954], No. 36777/55. Class 106 (1). Electrical apparatus for effecting conversion between decimal and non-decimal notations comprises a first and second register adapted to store values in decimal and non-decimal notations respectively, first and second transfer means respectively associated with and conditioned by said first and second registers, and control means operable after entry of a value in either register to cause the transfer means associated with that register to operate so that the same value appears in the other register. As described, means V3, V4, Figs. 1B, 1D, are provided for transferring a decimal digit registered in the binary scale on four triggers ST1, ST2, ST4, ST8, constituting a register A, Figs. 1A, 1C, to a register B comprising ten ring- connected trigger stages ST0, ST1 ... ST9, Figs. 1B, 1D (only the first five being shown), and means V2, Figs. 1A, 1C, are provided for transferring a digit from the register B to the register A. The multi-collector transistors in the cathodes of the triggers of register A are so arranged that the only wire of ten decimal-digit wires W4 which is not carrying current is the one whose reference number is the same as the digit in the register, and thus of ten triodes V3 only one is not conducting to open its associated gate tube V4. Then when a positive transfer pulse is applied to the control grids of all the tubes V4 via wire W7 it passes through only the " opened " tube and sets the associated stage in register B in the " on " condition, thereby effecting the transfer of the digit in the A register to the B register. The transfer pulse in addition to passing through one of the tubes V4, will also pass through a tube V4A, Fig. 1B, if the digit being transferred is not zero, to set the first stage of the register B in the " off " condition. This is necessary since immediately before a transfer to register B, the register is zeroized by a positive pulse on wire W3B applied to the side of each trigger marked with a cross. Transfer from the register B to the register A is effected in a similar manner by a pulse on a wire W5 which passes through one or more of gate tubes V2 depending upon the particular trigger " on " in the register B. A transfer pulse control gating circuit is provided (Fig. 1G, not shown) for zeroizing the register into which transfer is to take place before a transfer pulse is applied, and also for testing that the register has in fact been zeroized before the transfer pulse is applied. Each of the registers A and B shown can count up to nine pulses applied to its socket PS1, after which it again starts counting from zero, and each could form one decimal denomination of a multi-order counter or accumulator, but the inter-denominational carry means are only shown in block form (Fig. 2, not shown). Specification 595,553 is referred to.

Abstract: 304,650. Gotham Knitbac Machine Corporation, (Assignees of Leavin, W. H., and Leavin, S. B.). Jan. 23, 1928, [Convention date]. Darning.-Runs and ladders in knitted goods are repaired by apparatus which first spaces the transverse threads of the run at equal distances apart, and then feeds them forward at a uniform rate for automatic looping by a mechanically operated needle. The article to be repaired is placed on a support 74 so that the run 80, Fig. 13, is under the needle 9, and the transverse threads c are placed across the teeth 34 of the spaced discs 33, Fig. 12, protruding through a slot in the guard plate 32. The machine is driven, in the example shown, by a motor 30 to cause a shaft 27 to rotate the eccentric 45 to rock rods 25, 44. The rod 25 rocks the lever 20 about its pivot 21 to reciprocate the sleeve 6 carrying the latch needle 9. Adjustment of the needle-lift is made by the sliding sleeve 22 held by the set screw 23. A cam 12 enables fine adjustments of the needle to be made. The rod 44 rocks the lever 39 about its pivot 40 to cause the pawl 38, Fig. 4, to feed the work by engaging the teeth of the disc 33. A feed wheel 59 is glared to the disc 33 to move at the same rate and has a spring roller 70 carried by rods 68, 69 in the presser bar 62 to assist the feed. The feed is varied by the adjustable sleeve 41. The presser foot 61 is bifurcated. The flywheel 28 is turned by hand till the needle, with the latch 17 up, is just below the transverse thread at the beginning of the run to be repaired. It is then rotated till the hook of the needle lifts the thread. While this is happening, the disc 33 has carried the next thread forward so that when the needle descends and ascends under the action of the power drive, it pulls the second loop of thread through the first loop and casts off by the fallen latch in the usual way with the next loop within the hook 15 ready for the continuation of the process.
