Title: Improvements in or relating to electric switches
IPC: H01H1/26
Filed: 1962-12-20
Abstract: 1,024,577. Cam-operated switches. EUROPE MANUFACTURING TRUST REG. Dec. 20, 1962 [Dec. 21, 1961; May 28, 1962, Sept. 21, 1962; Sept. 27, 1962], No. 48144/62. Heading H2B. In an electric switch a moving contact blade is mounted in a slot in a support, so as to be capable of a rocking movement, and is held by resilient means in contact with an actuating member such as a cam. In one construction, a movable plate 1, Figs. 1 and 2 (not shown), carrying contacts 3, 4, has extensions 7, 7a which pass through slots in the switch casing 18, these providing pivots when the plate is rocked by a cam 13 engaging an extension 14 on the plate 1. The plate is held in engagement with the cam by a spring 12 and its actuation moves it between fixed contacts 5, 6. If desired, it may be corrugated to make it more flexible. In another embodiment, a U-shaped member, slidable in grooves in the casing, transmits the movement from the cam to the plate. Two or more switches may be ganged together and have indexing means mounted on the shaft between adjacent switches. Such indexing means preferably comprises a suitably shaped cam associated with a locating spring blade.

Abstract: <PICT:1094066/C6-C7/1> <PICT:1094066/C6-C7/2> Steel is produced from scrap and/or pig iron in an open hearth furnace with one or more oxy-fuel burners inserted through the roof, by a process in which during the melt down period at least 60% and preferably 70 to 80% of the oxygen required for complete combustion is supplied through the roof burners.  The remainder of the oxygen is supplied as pre-heated air through the regenerator chambers of the furnace.  During the subsequent refining period oxygen is supplied via the burners in at least the stoichiometric relationship required for complete combustion of the fuel and preferably in an excess of 10% to 20%.

Title: Coin Handling and Wrapping Apparatus and Means to Detect Irregularities in the Operation Thereof.
IPC: G07D9/06
Filed: 1967-10-26
Abstract: 1,177,669. Coin wrapping apparatus. TENSHIN KAHEI KEISANKI K.K. 26 Oct., 1967 [27 Oct., 1966], No. 48818/67. Heading B8C. A machine for handling and wrapping coins comprises means for successively selecting, counting and stacking the coins. The stacks of coins are measured and wrapped in a web, and a monitoring device operates to stop the machine if one or more parts of it functions incorrectly. Stacking.-After selection and counting (see also Specification 1,158,450), the coins fall through a passage 50, Fig. 4, to a stacking cylinder assembly which comprises a pair of cylinder halves 54, 55, Figs. 4 and 5, hinged together by a vertical, pin 56. The assembly may be opened or closed by the activation of a solenoid 64. The diameter of the enclosed cylindrical cavity is controlled by means of an adjustable cam 68 and stop 66 to suit the size of coin being handled. When a desired number of coins has been counted by the counter 6, a signal is generated, stopping the motion of discharge wheel 3. A lever 77 moves across and then downwardly to contact the top of the stack of coins, and if the number of coins in the stack is insufficient, the lever 77 will move below a preset position so that a switch (75), Fig. 6 (not shown), is triggered. This causes reversal of the motion of lever 77 and also the removal of a bottom-plate 111 and consequent discharge of the stacked coins. Wrapping.-A complete stack of coins is transferred from the stacking assembly 51 to a wrapping position by gripping levers 77, 83 which hold the stack between pins 77a, 83a. The operation of the levers 77, 83 is controlled by a system of cams, Fig. 7 (not shown). A wrapping-web feed mechanism, Fig. 9, comprises a feed roller 178 which feeds the web W towards wrapping rollers 161, 162, the web being guided by a plate 186, near which is mounted a knife 181. The stack is brought by levers 77, 83 into contact with rollers 161, 162. A pressing roller 163 is now moved to the position shown in Fig. 9, and the simultaneous rotation of rollers 161, 162, 163 causes the web W to be wrapped around the stack. Beads are now formed in the web at each end of the stack by hooks 188, (187), Figs. 7, 8 (not shown), to hold the web about the stack. The web feed is now stopped and the continued rotation of rollers 161, 162, 163 stretches the web and causes it to be severed by the knife 181. Satisfactory feeding of the web is detected by a switch 194 actuated by a blade 197 which is moved in an anti-clockwise direction by the action of the web when the latter is pulled into its stretched position. If switch 194 is not actuated, the machine is stopped, when the web may be repositioned. After satisfactory wrapping, the completed stack is allowed to fall from the machine. An electrical circuit for controlling the apparatus is also described, Fig. 10 (not shown).

The indicator 42 has one, two, three or more arms 44 that project through slots 48 in the cover 30, and in Fig. 1, the slots are formed so that the cover can only be fitted when the indicator 44 is in its lowermost position and the valve is closed. Each arm 44 has an aperture 45, and is slidable on a pin 46 mounted on a gland 9. Stem 6 is formed in two parts, viz. a lower part, which is formed as a usual valve stem, and an upper part fitted thereto by pins 50. The stem can be formed as one piece. A padlock keeper can be passed directly through the aperture in the swivel 24. The pins 46 can bear on the side of the arms 44 to prevent rotation. The cover 30 can have a number of slots 48 of different lengths. An arm 44 could be bent downwardly to extend below an unslotted cover.

Title: Electric motor control system
IPC: H02P7/292
Filed: 1975-12-19
Abstract: 1535748 Automatic control of current and speed GENERAL ELECTRIC CO 19 Dec 1975 [20 Dec 1974] 52125/65 Heading G3R The current taken by an electric motor is limited by controlling the power supply in dependence on a direct comparison between measured motor current and a time-varying reference signal. The periodic generation of the reference signal is dependent upon a given condition in the supply circuit.  As shown in Fig. 1, a load 14 is driven by a D.C. motor 10 supplied from a three-phase source 19 over a thyristor bridge circuit 18. A tachogenerator 30 produces a voltage proportional to the motor speed for comparison with a manually set desired speed signal in a circuit 26. The resulting error signal controls the production of thyristor firing pulses in a generator 20. The error signal is prevented from reaching the pulse generator 20 if an inhibit signal is produced on a line 54 by a current limiting arrangement 40 responsive to the output of a current sensor 52 fed through a bridge rectifier 48. Voltage limiting is also provided by a feedback line 34. The current limiting arrangement 40 includes a sawtooth reference voltage generator 42 which is periodically reset by a signal on a line 45 produced whenever a thyristor firing pulse is produced by the generator 20. The reference voltage is supplied to a comparator 44 together with the measured current signal from bridge 48. When the current signal exceeds the instantaneous reference voltage value, the inhibit signal is produced on line 54. Examples of the circuits 42, 44 are described with reference to Figs. 2 and 3 (not shown).
