Title: An improved permutation locking device for controlling switches or lock bolts
IPC: E05B37/00
Filed: 1920-09-08
Abstract: 171,235. Houston, A., and Stephenson, H. P. Sept. 8, 1920. Switches, locking and unlocking.-Slotted discs 1, 2, Figs. 2, 3, and 6, control a pivoted lever 9 operating a lock bolt or carrying switch contacts of a controller on a motor vehicle, and the discs are displaced from their " set " position on the completion of movement of the lever in either direction. The disc 1 is fixed to a spindle 3 carrying a mutilated pinion 11 and an operating knob 37 with face plate 34 and pointer. The disc 2 is fixed to a sleeve 4 on the spindle 3, which sleeve also carries an annular dial 32, similarly divided at its inner and outer circumferences and operated by a knob 36. The discs are mounted between plates 22, 23 separated by spacing pillars 24 and mounted on an insulating block 45, the whole being enclosed in a casing 46. Slots or grooves 5, 6 are formed in the discs 1, 2, the outer portions of the slots being struck from the pivot 10 of the lever 9 and the inner portion being enlarged, whereby after setting of the discs and operating of the lever by external means so that the pins 8 thereon pass into the slots, the discs can be rotated, the disc 1 by teeth 17 on the lever engaging the pinion, and the disc 2 by a toothed lug 18 on the lever engaging pins 19 or teeth on the disc, so that the combination is scattered. The lever can thus be moved to operate the lock bolt so as to close the switch by bringing contacts 40, 41 thereon over fixed contacts 42, 43, and is arrested in this position by a tooth on the pinion engaging a shoulder 50 on the lever. On the return movement of the lever and after its pins 8 leave the slots 5, 6, the discs are rotated by teeth engaging the pinion and a lug 20 on the lever engaging a pin 21 on the disc 2, thereby rendering re-setting necessary before the lever can be again operated. A spring catch 68 depressible by a rod 71 from the exterior of the casing may be provided to lock the lever. Free movement of the discs is prevented by pivots 25, pressed by springs 30 against serrations 28 on the discs. In a modification, the slotted discs 54, 55, Fig. 7, are arranged on parallel spindles 56, and the lever 62 is pivoted on the axis of, and fixed to, the mutilated pinion 60 which operates the discs as described above to displace the setting. The discs may be of insulating material and may have luminous dials, and their spindles serve as the terminals to be connected by the lever when the projecting pins 63, 64 enter the slots.

Title: An improved apparatus for matching impedance
IPC: H01P5/04
Filed: 1945-10-05
Abstract: 600,519. Impedance-matching. WESTERN ELECTRIC CO., Inc. Oct. 5, 1945, No. 26052. Convention date, Oct. 14, 1944. [Class 40 (viii)] Apparatus for matching the characteristic impedance ZO1 of a wave-guide 2 to the impedance of the antenna leads 14, 17 in parallel, consists of an adjustable plug 18 positioned opposite the end of the wave-guide and protruding into the paths leading to the two antenna heads, together with an adjustable probe 21 projecting through the plug into the wave-guide itself. The plug is stated to act is a shunt capacitive impedance changing the complex impedance of the antennae into a second complex impedance, and the probe to act as a series impedance transformer, which changes the second complex impedance into the resistive impedance of the waveguide. The use of the probe enables transformations to be effected in which use of the plug 18 alone could only transform the antenna impedance into an impedance whose resistive part is less than that of the waveguide. Specification 595,893 is referred to.

Patent GB-187214-A (GB)
IPC: B66B1/50
Filed: 1922-09-28
Abstract: 187,214. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Baruch, M.). Oct. 10, 1921, [Convention date]. Electric plant.-Relates to lifts in which the cage is actuated by a reversible electric motor provided with a controller having an operating handle or switch which may be moved by the attendant to up, off, and down positions for raising, stopping and lowering the cage. The object is to provide a levelling system which will automatically cause the car to assume a position in which its floor is level with the landing in the event of the operating switch being put to the off position when the cage is not exactly opposite the landing. Attached to the cage 11 is a steel or other tape 12 passing over sheaves and carrying projections 20, one corresponding to each landing. In a suitable position adjacent to the tape 12 is mounted a box 40 in which are mounted spring fingers 31, 32 which can be actuated by the projections 20 so as to close one or other of the contacts 37. The box is suspended so that on the excitation of an electromagnet 45, these fingers are withdrawn from the path of the projections 20. The electromagnet 45 is excited whenever the operating switch is out of the off position, so that the levelling fingers do not then come into the path of the projections. The fingers are shaped so that if the operating switch is put into off position when the cage is near but not at a landing one of them is depressed by one of the projections 20, and one of the contacts 37 is closed. One of these causes the up solenoid of the cage-actuating system to be excited and the other the down solenoid, resulting in an adjustment of the position of the cage.

Title: Improved yarn bunching motion for use in ring spinning and ring doubling frames
IPC: D01H1/36
Filed: 1931-09-19
Abstract: 373,891. Bunch-building motion for ring spinning and doubling frames. HOWARD & BULLOUGH, Ltd. and BOWLER, S., Globe Works, Accrington, Lancashire. Sept. 19, 1931, No. 26245. [Class 120 (ii).] The doffing-quadrant of ring spinning and doubling frames is automatically operated through a lever system and a scroll to impart the necessary motion to the ring rail for winding a bunch of yarn at the base of the pirn prior to the normal building. A scroll 25, driven from the front bottom roller, oscillates through levers and links 28, 33, 34, 42 an arm 38 connected to the shaft of the pinion 40 of the doffing- quadrant 24. Prior to starting, the heart-cam is released by disconnecting a clutch 43 in the driving gear, the clutch lever 44 being maintained in position by a catch 45. The heartcam is set so that the bunch winding is correctly positioned on the bobbin by means of a handle 48 and gearing 47, the engagement of a pawl 51 and cam 49 determining the position. When the bunch is fully wound, the catch 45 is released by an extension 37 on the lever 34, the scroll 25 being designed to give the additional movement for this purpose. The catch 21 which, as usual, engages a stop 20 on the doffing-quadrant during normal building may be held in the disengaged position by a spring catch 56, so that the quadrant may be manually controlled for doffing purposes by the arm 38, which is pivoted to the shaft 39 of the pinion 40 and is moved free from the link 42, as shown in dotted lines, Fig. 7, for this purpose. When the arm 38 is returned to the full line position to engage the link 42 it disengages the catch 56.

Title: Improvements in remote position control systems
IPC: G05D3/14
Filed: 1950-10-27
Abstract: 693,506. Electric follow-up systems. BRITISH THOMSON-HOUSTON CO., Ltd., and STOKES, J. A. Sept. 25, 1951 [Oct. 27, 1950], No. 26278/50. Class 40 (i). In a remote control system using coarse and fine Selsyn systems, wherein both coarse and fine error signals are applied to a common control channel, and the coarse error voltage is blocked by normally non-conductive means until it reaches a predetermined value, a stabilizing voltage derived from a feedback channel from the receiver driving motor is mixed directly with the coarse error voltage, but is passed through a further network before mixing with the fine error voltage. As shown, the control member 11, Fig. 1, operates the controlled member 10 through coarse and fine Selsyn systems 14-18, 15-19, the coarse and fine error voltages developed in the respective transmitter rotors being applied over lines h-g, a-b by way of a common control channel f-e to an amplifier and demodulator 25 which controls the magnitude and sense of the energization of the field of a motor driven generator 13 which drives the servomotor 12, and with it the load 10 in the follow-up sense. The coarse error voltage is applied over a transformer 32 and rectifiers 34, 35, Fig. 2, to the grids of triodes 28, 29, coilnected reversely in parallel. For small deviations from correspondence of the members 10, 11, the triodes are blocked by the bias applied by batteries 30, 31, and the fine error voltage applied over high impedances Z to the line f-e controls the servo-motor 12. Hunting of the system is prevented by a feedback voltage derived from the motor circuit in known manner and applied through a channel 26 and a network 27 across one of the impedances Z. When the deviation reaches a predetermined value the triodes 28, 29, conduct on alternate half-cycles, and apply an amplified version of the coarse signal to the common channel f-e over the transformer secondary 33, in series with the anti-hunt feed back voltage in channel 26. At the same time the shunting action of the conducting triodes across the line a-b attenuates the fine error signal to render it innocuous. The stabilizing negative feedback voltage derived from the channel 26 is a simple function of velocity and, or acceleration, whereas the network 27 produces a more complex function of these values. Specification 576,117 is referred to.
