Title: Improvements in or relating to arc welding
IPC: B23K9/067
Filed: 1948-02-09
Abstract: 650,465. Electric welding. PHILIPS ELECTRICAL, Ltd. Feb. 9, 1948, No. 3729. Convention date, Feb. 12, 1947. [Class 83 (iv)] In electric arc welding, e.g. bolts to workpieces a solid slag forming mass which is somewhat conductive but has a high electrical resistivity is used to initiate the arc, which mass does not evolve gas during arcing. The size and shape are chosen so that the bolt &c. is contacted automatically at therequired instant with work without using complicated control mechanism. One solid comprises 15 per cent calcium carbonate, 13 per cent calcium fluoride, 12 per cent bentonite, 2 per cent ferro-manganese, 3 per cent ferro-silicon, 2 per cent ferro-titanium and 53 per cent pulverulent iron by weight and is heated at 800‹ C. in non- oxidizing atmosphere to render it non-gas evolving. A further mass is made by compressing substances not gas evolving, e.g. 18 per cent calcium oxide, 13 per cent calcium fluoride, 12 per cent pulverulent glass, 2 per cent ferro-manganese, 3 per cent ferro-silicon, 2 per cent ferro-titanium, and 50 per cent pulverulent iron.

Patent GB-998248-A (GB)
Title: Transmission devices for coupling a driven shaft to a driving shaft
IPC: F16H27/06
Filed: 1962-01-31
Abstract: 998,248. Gearing for starting and stopping machinery. K. ZUSE. Jan. 31, 1962 [Feb. 2, 1961; Feb. 3, 1961; Sept. 20,1961], No. 3771/62. Heading F2L. A transmission for accelerating a driven shaft up to a desired speed, rotating it at that speed and subsequently decelerating the shaft, comprises a Geneva mechanism engageable to accelerate and decelerate the shaft and a gear and clutch arrangement for driving the driven shaft at the desired speed. A driving shaft I carries a disc 3 having coupling bolts 5 mounted thereon which are axially slidable to engage rollers 6 in slots 23 of a Geneva wheel 22. Each coupling bolt 5 is fast with a control means 8 having cams 8a, 8b which at one position around the periphery of the driving disc 3 co-operate with a roller 10 carried by a bell-crank lever 9. Energization of a solenoid 12 pivots lever 9 so that the roller 10 engages the cam 86 and retracts the bolt 5 so that the roller 6 will not engage a slot 23 of the Geneva wheel. Deenergization of the solenoid permits a spring 13 to shift lever 9 so that roller 10 engages the cam 8a and the roller engages a slot 23 to drive the Geneva wheel. When the Geneva wheel is at its maximum speed the bolt 5 is withdrawn by the action of a second solenoidcontrolled bell-crank lever 16, and the drive is now taken over by way of gears 20, 21, and a clutch arrangement. The gear 21 is freely mounted and is clutched to the Geneva wheel 22 by way of a roller 29 engaging a depression of a cam 35 fast with the wheel 21, the roller 29 being rotatably mounted on a cranked lever 26 which also carries a roller 27 engageable with depressions in a stationary cam 34. The lever 26 is pivotally mounted on the Geneva wheel 22 and has an arm 30 engageable with a spring-pressed roller 31 to form an over-centre arrangement, the arrangement being such that initially with the driven shaft at rest the roller 27 engages a depression in cam 34 to station the driven shaft, upon roller 6 engaging a slot of the Geneva wheel roller 27 rides up a lobe of the cam 34 until when the Geneva mechanism has attained its maximum speed the lever 26 moves over-centre and the roller 29 engages a depression of the cam 35 to clutch the gearwheel 21 to the Geneva mechanism 22. To decelerate the driven shaft a roller 6 is projected into a slot 23 by the bell-crank lever mechanism 16 so that the Geneva wheel is decelerated as the roller proceeds radially outwardly of the slot, the roller 29 riding out of the cam depression until the lever 26 moves over centre at the time when the driven shaft becomes stationary so that the roller 27 engages a depression of the cam 34 to hold the driven shaft stationary. Specification 998,249 is referred to.

Title: Improvements in or relating to sound records
IPC: G11B5/70
Filed: 1929-02-05
Abstract: 333,154. Pfleumer, F. Feb. 5, 1929. Records, magnetic and electromagnetic. - A magnetic sound-record strip is prepared by sticking magnetic powder on a backing strip, the powder being steel or iron containing hydrogen prepared electrolytically, or alloy of nickel or iron, e.g. ferro silicon. The powder may be prepared by mixing an organic binding material, e.g. molasses or sugar with soft iron powder which on being caramelized and carbonized turns into steel and is hardened by quenching, and is then dried and re-ground. In powder form where each grain is less affected by its neighbours, the records are said to keep longer. The powder may be attached to kinematograph films. The original strip may be used for duplicating. Instead of a strip a cylinder or plate may be used.

Title: Improvements in or relating to the regulation of long distance alternating current lines
IPC: H02J3/16
Filed: 1929-02-05
Abstract: 328,984. Siemens - Schuckertwerke Akt.-Ges. Dec; 5, 1928, [Convention date]. Systems depending on two or more machines; regulation, automatic; transmission conductor arrangements. - Wattless current compensating arrangements, such as synchronous or asynchronous machines, choking coils, condensers, &c., which may be distributed in series or m parallel with a long distance transmission line are each controlled by a device responsive to equilibrium between three quantities, viz., the inductive wattless power due to the current flowing in the line, the capacity wattless power due to its potential and the wattless power fed in at the compensating station. Each station may be assigned a definite portion of the line for compensation and a relay responsive to excessive voltage or wattless current flow between line and station may change the setting of the controlling devices to cause a station to furnish compensation in respect of a portion of the line not compensated by reason of failure of the compensating devices at any station. Fig. 2 shows diagrammatically a synchronous machine K at one station the excitation of which is varied by a reversible motor in response to the movements of a controlling device having four Ferraris discs 1 - - 4 producing torques proportional respectively to 1, the square of the line voltage, 2, the product of the line voltage, the current flowing between the station and the line, and the sine of the phase angle between them, 3, the square of the current in the section L1 of the line and 4, the square of the current in the section L2 of the line; when the first is in equilibrium with the sum of the remaining torques the controlling device is in its initial position. A regulation to constant or approximately constant voltage may be obtained if the disc 1 and its magnet is replaced by a spring, the voltage being determined by the spring tension. If the station is a generating station the controlling arrangements may operate upon the field of the generators. The adjustment of the elements of the controlling device is determined by the constants of their magnet circuits, and these may be adjusted to compensate for two definite lengths of line L1, L2; the relay changing the setting in response to failure of any compensatory arrangement may operate a switch to vary these constants. In place of mechanical forces direct currents may be produced corresponding thereto, by the aid of rectifiers and capable of being added together.
