Title: Improvements in loop regulating mechanism for full fashioned hosiery knitting machines
IPC: D04B11/00
Filed: 1931-09-25
Abstract: 372,673. Straight - bar knitting- machines. HAINES, J., Meadowbrook, Pennsylvania, US.A. Sept. 25, 1931, No. 26822. [Class 74 (ii).] In flat knitting-machines, the size of the loops is regulated by a shaft carrying an element which is adjusted automatically by a member carrying a series of stops adapted to be substituted one for another to determine different positions of rest fcr the element in accordance with the size of the loops to be formed. In a straight-bar knitting-machine in which a presser motion determining the size of the loop is effected by oscillating a needle bar 10 on its supporting arms 12 by a cam 17 on a main shaft 16, the cam operating through a roller 19 on a depending arm 18 adjustably linked to an arm 10a depending from the needle bar 10, the approach of the roller 19 to the cam 17 is limited by an arm 24 rigid with a loop-regulating shaft 23. A cam 32 on the shaft 16 rocks the shaft 23 through a roller 31 on an arm or lever 30a loosely mounted on the shaft but engaging an adjusting screw 35 on an arm 30b secured to the shaft, and the spindle 33 of the roller 31 is mounted in the end of the lever in eccentric bearings which allow of adjustment of the extent of the rocking of the shaft 23. To effect this automatically, a pinion 37 on the spindle 33 meshes with a gear 38 on a shaft 39 rotatable in a bearing 40 carried by the lever 30a, and an arm 42 provided with upper and lower rollers 43, 44 is secured to the lower end of the shaft. The upper roller 43 coacts with a cam member 45 loosely mounted on a sleeve 49 itself loose on the shaft 23. The cam 45 is connected by a link 70, lever 68, link 67, and lever 64 to a cam 60 on a shaft 57 which is intermittently rotated by an eccentric 86 on the main shaft 16 whenever a pawl 82 coupled to the eccentric is allowed to drop into an operative position by the lowering of a guard member 81 when buttons 72 on the measuring chain 71 of the machine rock a lever 79 connected to a link 80 on which the guard is mounted. The cam 45 also supports a pawl 54 adapted to engage a toothed ridge 47 on the sleeve 49 to rotate it, overrunning being prevented by the co-operation of a spring detent 56 with a serrated ridge 48 on the sleeve. Another ridge 51 on the sleeve 49 is notched to receive adjustable stops 52 which are successively engaged by the lower roller 44 on the arm 42. In operation, when the cam 60 reciprocates the link 70 and thereby simultaneously oscillates the cam 45 and rotates the sleeve 49, the cam moves the arm 42 aside out of the path of the stops 52 and the sleeve brings another stop ready for engagement with the roller 44. The new stop maintains the arm 42 in a fresh .position and the alteration is communicated by the bevel wheels 38, 37 to the eccentric bearings of the spindle 33 of the cam roller 19 to vary the amount by which the cam 32 rocks the shaft 23 and its arm 24 by which the size of the loops is regulated.

Inventor: KOLLAR JOHN
IPC: C07F11/00
Filed: 1965-06-28
Abstract: Molybdenum and vanadium salts of C5- 50 carboxylic acids, which salts are soluble in liquid hydrocarbons, are prepared by heating an oxalate group containing compound of molybdenum at valence + 6 or of vanadium at a valence + 5, with a C5- 50 carboxylic acid at a temperature of at least 140 DEG  C. for at least 2 hours.  The preferred oxalate compounds are those obtained by heating 0.5-1.2 mols. of an inorganic compound of Mo+6 or V+5 with 1 mol. oxalic acid in the presence of 0.5-50 parts by weight water ser part oxalic acid, using sufficient water to dissolve the Mo or V compound, at 100-150 DEG  C. under a pressure sufficient to maintain a liquid phase, for 1-2.5 hours, and then removing the water.  This reaction may be effected in the presence of the C5- 50 carboxylic acid.  Molybdenum trioxide and vanadium pentoxide are the preferred inorganic compounds. It is preferred to use alkyl, alkenyl or aralkyl mono-carboxylic acids.  Examples relate to the preparation of hexanoates, octanoates and naphthenates of Mo and V.

Abstract: 964,648. Gyroscopic apparatus. BENDIX CORPORATION. July 10,1963 [July 11,1962], No. 27359/63. Heading G1C. A rate gyro is provided with means for testing gimbal freedom and rotor speed. As shown, the rotor 16 has eight permanent magnet rods 100 equispaced about, and parallel to, its axis so that as the rotor 16 rotates, a voltage is induced in a coil 125, whose axis is perpendicular to that of rods 100, which is proportional to the speed of the rotor. This voltage may be applied to a voltmeter, or to the Y axis of an oscilloscope, the motor excitation voltage then being applied to the X axis so that a hissajous pattern is created. To check gimbal freedom, a direct current is applied to coil 125 and this reacts with the rods 100 to produce a torque about the output axis 12-12 so that movement of the gimbal 14 may be measured by the normal pick-off 50, 52.

One lead 17 from the lamp 54 is connected to a resistor 76. The other lead and a lead from the resistor are crimped within the folded back ends of the conductors, the fold being corrugated by a suitable crimping tool. The base portion 2 has an I-shaped extension at the rear, in opposite sides of which leads 30 are secured to the conductors 28. For use with thicker panels, the fin members may be slotted successively to release fingers contacting the rear of the panel during insertion.

Abstract: A drug destined for injection is compressed under a pressure of at least 2500 Kg/cm.2 to a solid body which is subdivided to particles having a maximum size of 250 microns and suspended in a parenterally acceptable liquid carrier in which the drug is substantially insoluble.  Alternatively, especially if the drug is soluble, it may be mixed with a solid carrier which is sparingly soluble in the liquid medium before compression. Examples of drugs are: heparin-butacaine, glucagon, insulin (amorphous and coupled with salmine), insulin and glucagon, ACTH, ACTH-protamine-zinc, lipoic acid, thyrotropic hormone, antidiuretic hormone, testosterone, procaine-penicillin, heparin, Vitamin B12, atropine tannate.  Zinc, aluminium and tricalcium phosphates are specified solid carriers. The liquid carrier may be aqueous or an oil and may contain additional agents which retard the resorption of the active substance, e.g. gelatine, dextrans or other high molecular weight polysaccharides. Metal ions, e.g. zinc, which effect the period of action of certain drugs may also be present.  The suspensions may be lyophilized to give a powder which may be resuspended in a suitable liquid carrier before use.
