Abstract: 733,777. Dobbies for looms. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. Oct. 20, 1952 [Aug. 2, 1951], No. 18294/51. Class 142(2). In a positive double-lift open-shed dobby, each baulk lever is provided at each end with a pivoted hook, each hook having an extension which is acted on by a feeler lever controlled by a pattern chain for determining whether or not the hook engages the adjacent reciprocating knives. Hooks 15, 16 at the ends of each baulk 12 have portions 15c, 16c engaging knives 17, 18, and extensions 15d, 16d acted on by feeler levers 21, 26 controlled by a pattern chain 24. A spring 27 urges the levers against the extensions and against the pattern barrel 24x. Each baulk pivots on a stud 11a carried by a jack 10 mounted on a pivot 11. The knife 17 is carried by levers 28 and the knife 18 by levers 30, the levers being connected by links 32. The mounting for the knives is flexible. Rollers 33, on the levers 30, engage cams 35 on a shaft 36 driven by gears from the loom top shaft and oscillate the knives. The cams are so designed that one end of each knife is advanced with respect to its other end. At the inward end of the traverse of the knives the hooks are relieved from stops 19, 20 and can be freely rotated by the feeler levers. The shaft 36 carries the driving member 40 of a Geneva motion, the driven member 43 of the motion being mounted on the pattern barrel shaft 44 so that the knives are oscillated in timed relationship with the pattern control. Movement of a handle causes a rod to press on and remove all the upper hooks from the knife 17, and a second rod to press on and engage all the lower hooks with the knife 18 so that the baulks can be moved to a mid position to give a closed shed.

IPC: G05D23/24
Filed: 1958-06-11
Abstract: 882,312. Automatic temperature control systems. ZAVODY PRUMYSLOVE AUTOMATISACE, NARODNI PODNIK, PRAHA. June 11, 1958, No. 18715/58. Class 38 (4). [Also in Group XXXIX] In a control system a relay is operated from an A.C. source through rectifiers and the output windings of a magnetic amplifier, the latter are connected to a magnetic amplifier control winding to render the magnetic amplifier bistable, the energizations of mutually opposing further control windings are dependent on an adjustable resistor and a resistor automatically adjusted in dependence on a variable respectively, and non-rectangular periodic pulses are applied to a control winding of the magnetic amplifier. In Fig. 3, pulses produced by an oscillator 3 supplied from a D.C. source 1 are applied to a control winding 8 of a magnetic amplifier which thus causes, through a rectifier 5, intermittent operation of a temperaturecontrolling relay 20. Variations of the controlled temperature from a desired value influence a temperature-variable resistance 14 controlling the energization of a second control winding 9 of the magnetic amplifier so that the ratio of on to off time of relay 20 is adjusted in the appropriate sense to restore the temperature to the desired value. The desired value may be set by adjusting a resistor 13 which controls the energization of control winding 8. The magnetic amplifier is provided with a feedback winding 7 so that rate of change of output current is dependent on the magnitude of the controlling flux. A meter 15 associated with a bridge circuit including resistance 14 serves to indicate the temperature, a non- inductive winding 10 on the magnetic amplifier providing compensation for the effect of temperature on winding 9. A rectifier 16 or 25 protects meter 15 against open-circuiting of the leads to resistance 14. Replacement of oscillator 3 by a mechanically operated switch and/or application of the pulses to separate control windings is referred to. In a modification, Fig. 4 (not shown), a separate magnetic amplifier and associated relay is responsible to regulation in each sense.
