Title: Hollow carbon or graphite arc electrons
IPC: H05B7/085
Filed: 1969-04-15
Abstract: 1,271,681. Arc electrodes. C. CONRADTY. 15 April, 1969 [24 May, 1968], No. 19143/69. Heading H5H. [Also in Division C1] To prevent the escape of arc stabilizing, ionizing gas through the porous walls of a hollow carbon electrode, the bore is made gas impermeable. Various sealing procedures are described. The surface of the bore may be sealed by carbonizing materials in the absence of air, suitable impregnating materials being tar, pitch, synthetic resins or sugar solutions. The bore surface may be impregnated with waterglass and then heat treated so that the pores are filled with silica. Pyrolitic carbon may be deposited on the surface of the bore to render it gas-tight. Metallic coatings may be used to effect sealing, deposition being effected by electrolysis or by the decomposition of organic metallic compounds. Instead of coating the surface, a metal tube or gas impermeable carbon or graphite tube may be pressed into the surface of the bore. The sealing materials may also assist in stabilizing the arc, suitable ionizing additives being potassium fluoroborate potassium sulphate, tungsten carbide, or titanium carbide. Gunite can also be used as sealing process.

Title: Improvements in or relating to power transmission mechanism
IPC: F16H61/02
Filed: 1929-06-24
Abstract: 331,380. Hardy, W. G. June 24, 1929. Variable-speed gearing of the sliding spur-wheel type comprises an arrangement of a clutch j<1> for facilitating gear change in which the reversed drive is transmitted otherwise than through such clutch. The clutch is of a type hitherto used between the change-gearing and the road wheels of a vehicle outside the gear-box in which there is a baulking-ring such as j<6> which prevents automatic. re-arrangement of the clutch until the driving and driven members of the clutch synchronize as described in Specification 306,636. The driven shaft, which is in line with the driving-shaft b, is divided into two parts c, c<1> adapted to be positively connected by this clutch j<1>, which is disengaged during speed-changing by way of a rod j<5>. The reversed drive is effected in the configuration shown independently of the clutch through gear train #, #<1>, g, h<2>, h<3>, i. To bring in lowest forward speed, which is also independent of the clutch, reversing sleeve h is moved to the left and a sleeve g<1> is moved to the right so that countershaft pinion g<4> drives gear i fast on tail shaft c<1>. Three higher forward speeds are im. parted to the shaft c, so that the corresponding drives must pass through clutch j<1>. Two of these are countershaft drives through gears #<2>, #<3>, respectively, and top speed is direct through clutch #<7>, #<6>.

Title: Improvements in or relating to machines for testing the amount of twist in yarn thread and the like
IPC: G01N3/26
Filed: 1929-06-24
Abstract: 326,113. Fine Cotton Spinners' & Doublers' Association, Ltd., and Hutchins, F. June, 24, 1929. Yarns, testing.-In a machine for testing the amount of twist in yarn, the untwisting is effected by a power drive such as an electric motor, and is so arranged that the last few turns are taken out by a hand drive, pressure on the handle thereof engaging the clutch of the motor drive while release of the pressure puts the clutch out of action and puts into gear the mechanism for hand operation. The yarn to be tested is clamped at 21 on the end of the shaft 18, the length to be tested, measured by a scale 24, extending betwen the clamp 21 and a clamp 35 sliding on a rod 34, while the extension is indicated over a scale 40, the yarn being kept under tension bv a tension device 45. The motor 11 drives the shaft 18 through a belt 77 and through the clutch 76 normally kept out of engagement by a spring 70. In this position the drive is connected up to the handle 51 through pins 63 engaging the teeth of a bevel wheel 62 driven through gears 61, a gear 60 on a sleeve 46 carrying a disc 48 on which the handle 51 is pivotally mounted. Pressure on the handle pushes inwards a rod 73 which engages a spring 72 on the clutch lever 68. Counting mechanism comprises pointers 114, 124, Fig. 2, operated through worm and toothed gearing, clutches being provided to allow for zeroizing of the pointers, the lever 131 being depressed to raise the rod 138 for this purpose. The untwisting may be done in either direction and for this purpose alternative scales for the pointers 114, 124 are provided. Thus untwisting in one direction is indicated by scales on the board 88, Fig. 4, and untwisting in the opposite direction by scales on a board 89 hinged at 87, which scales when lowered into position cover up the scales of the board 88. The lowering of the board 89 depresses an upwardly extending arm 128 to operate the switch lever 125 to reverse the motor 11.

Abstract: 693,213. Striking plates for locks. DAVEY, W. C. July 25, 1949. No. 19517/49. Class 44 A striking plate, mounted for pivotal movement to release the latch bolt when required, is normally retained in the securing position by an abutment displaceable by means of an electromagnet the armature of which is mechanically retained in the attracted position after energisation and released when the striking plate is rotated. The striking plate 4 shown in Figs. 1, 2 in the securing position is pivoted at 5 in a box-like casing 1 and spring loaded to the securing position. A nose 10 on the striking plate rests on the pivoted abutment 8 which is retained by an arm 11 engaged with a spring loaded catch 12. Electromagnets 16 are arranged when energised to attract a pivoted L-shaped armature 15 the end of which abuts a peg 14 on the catch 12 which is thereby displaced to release the arm 11. A light blade spring 19 mounted on the abutment 8 is adapted to snap down behind the armature 15 and retain it in the attracted position. The striking plate 4 is now retained only by spring pressure and will turn to free the latch bolt 22 when pressure is applied to the door, as shown in Fig. 4. The spring 19 is then lifted clear of the armature which returns to the initial position, allowing the catch 12, abutment 8 and striking plate 4 to return to their initial positions ready again to secure the latch bolt when the door is shut.

Abstract: 1303078 Automatic speed-control JUNGNER INSTRUMENT AB 24 April 1970 [6 May 1969] 19729/70 Heading G3R A master object 1 such as the cable drum of a crane, and slave objects 2 are driven by hydraulic systems 3 comprising motors whose speeds are each controlled by changing the stroke of associated pumps. For this purpose, pilot valves 4 are connected to transistor circuits 5. The object 1 is coupled to a synchro transmitter 6 providing a signal representing the instantaneous position of the master object, this signal being applied to synchro comparators 7 which are coupled to the objects 2. A command signal is supplied to the master pilot valve from a transmitter 8, transformer 9, rectifier 10, and circuit 5. Output signals from the comparators 7 are combined with the command signal, and the corrected signals are applied to the respective pilot valves through rectifiers 10 and circuits 5. The resultant signal supplied to each pilot valve has a magnitude and polarity to remove deviations in relative speed between the master object and the corresponding slave object, thereby synchronising their position and movement. In a modification, Fig. 2. (not shown) a master and slave object are respectively geared to a synchro transmitter and comparator, the magnitude and polarity of the command signal being controlled by reversible movement of a handle, about a neutral position. The signal from the comparator is combined with the command signal, and the combined signal is applied to both pilot valves but in different senses. Relative speed or positional deviations are thus removed by opposed and simultaneous regulation of the two objects.
