Title: Improvements in analogue multipliers
IPC: G06G7/161
Filed: 1967-12-01
Abstract: A multiplier/divider analogue circuit comprises an integrating operational amplifier and capacitor circuit A 1 , C 1 receiving a constant voltage + V S over temperature compensating resistances R1a, R1b the capacitor being shunted by transistor TR 1 switchable by bi-stable BS. With transistor open, linear integration produces a negative going output increasing with time which is applied to inverting unity gain operational amplifier A 2 together with multiplying voltage V A , to produce output increasing with time from -V A to 0, applied to a level detector circuit comprising operational amplifier A 3 having feedback path containing resistances R6 to R9, oppositely poled diodes D 1 , D 2 , and variable resistance VR 1 setting trigger level to 0. An output positive to earth (logic 0) is developed until the output of A 2 reaches trigger level, at which the output switches to negative (logic 1) and the output of pulse shaper PS1 changes from negative (logic 1) to positive (logic 0) for application over diode D 3 of a three input AND gate also receiving over diodes D4, D5 the outputs of monostables MS1 and MS2 which are logic 1 in stable states. Thus the AND gate output switches to logic 0 to produce logic 1 from pulse shaper PS2, setting bi-stable BS to its SET state, closing transistor TR1, and opening TR2. Integrator A1 is reset after time proportional to VA. Similarly, the input of integrator A4, C2 receiving multiplier voltage Vb over variable resistance VR 2 is cut off by TR2 after time proportional to VA. Bi-stable BS on assuming SET state triggers monostable MS1 to close transistor TR4 to transmit the final output of A4, C2 to storage capacitor C 3 , and after a suitable readout time MS1 reverts, opens TR4, and triggers monostable MS2 to close TR3 for a suitable time to discharge A4, C2. MS2 reverts and triggers bi-stable BS to RESET for repetition of the cycle. The AND gate remains at logic 0 while either MS1 or MS2 are in unstable states, thus maintaining bi-stable BS at SET for the required interval. The stored signal on C 3 is applied to a high input impedance unity gain non inverting operational amplifier A5 whose output is shown mathematically to be proportional to V A V B /V S . Squaring may be effected by holding V A = V B and V S constant, while square rooting (Fig. 2, not shown) is effected by feeding back the output V M over an inverting unity gain operational amplifier to input V S , so that V M is proportional to #V A V B or to #V A if V B is held constant. The apparatus is applicable to a mass spectrometer as described in Specifications 1,167,341, 1,215,293 and 1,215,293 cog.

Title: Transfer assembly for presses

Filed: 1968-10-15
Abstract: A transfer assembly for a press includes at least one longitudinally movable feed bar 19, at least one gripper mechanism 20 carried by at least one feed bar for longitudinally moving a gripper finger mechanism 21 and at least one lifter mechanism 22 for raising and lowering at least one longitudinally movable feed bar 19, the lifter mechanism 22 comprising a lifter housing 30, a plunger 37 vertically slidably mounted in the housing 30 and extending upwardly therefrom, a bracket 41 carried by the upper end of the plunger 37 and having supporting and guiding rollers 42, 43 and 44 thereon, guide tracks 45 on the feed bar or bars 19 engageable with the rollers 42, 43 and 44 and means 48 for raising and lowering the plunger 37. To raise the feed bar 19 a rack 52 is moved to the left as seen in Fig. 6 by a longitudinally reciprocatable rod 25 which rotates the gear 48 in a clockwise direction thus raising the plunger 37 and hence the feed bar 19. To lower the bar the reverse procedure is carried out. Compressed air is supplied via a manifold 56 and connections 57 to a passage 58 which exerts an upward force on the plunger 37 for supporting much of the load of the feed bar 19. The gripper mechanism 20 and the gripper finger mechanism 21 are described in detail in Applications Nos. 48840/68 and 48839/68.

Patent ES-362480-A1 (ES)
Title: Numerical servo displacement control system
IPC: G05D3/20
Filed: 1969-01-14
Abstract: Apparatus for controlling the movement of a member includes a transducer feeding pulses as the member moves via a gate 42 (Fig. 2) to a reversible counter 30, the contents of which may be used to derive a control signal to position the member. In the embodiment described for maintaining the inter-record gap of data on tape at 40 units, when a stop signal is generated at terminal 31 when the tape is moving with full velocity a bi-stable 41 is set to open gate 42 and allow pulses to pass to counter 30. Gates 33 are simultaneously enabled so that an output voltage representing the count is compared at one input of differential amplifier 35 with a bias signal at terminal 30 representing a count of 20, the motor driving the tape consequently being stopped after 20 pulses. If a forward signal is then received gate 42 remains open until 20 more pulses have been received from the transducer when a zero or full detector 45 is enabled to reset bi-stable 41 to set counter 30 to zero (via gate 46) and enable a read/write gate 50 via gate 48 provided a "full velocity" signal is received at terminal 49. The outputs of counter 30 are not applied to the differential amplifier 35 since the gates 33 are closed, the only signal applied being a bias signal at terminal 36. If alternately a reverse signal is received counter 30 is counted down to zero when read/write gate is similarly enabled. The outputs of counter 30 are held at 40 units during this time by gate 57 so that a signal representing - 20 units is applied to the amplifier 35. Logic circuitry (Fig. 5, not shown) is described to ensure that no output pulses from the transducer are gained or lost when the tape changes direction.

Title: Metallurgical process using oxygen
IPC: C22B23/02
Filed: 1976-04-01
Abstract: A continuous autogenous multi-stage process for converting non-ferrous metal sulfides, in an oscillating, elongated, gently sloped, sealed, tiltable, rounded cross-section furnace, discharging crude metal or low-iron matte at one end, and silicate slag and sulfur dioxide-rich gas at the other end. The concentrates, fluxes, commercial oxygen, sulfur dioxide, a carbonaceous reducing agent and optionally other materials are introduced into the furnace in stages to provide a molten bath of slag and matte flowing countercurrently. Slag scavenging is accomplished by deconverting to produce low grade, cleansing matte in situ in the slag layer, followed by settling. At least a substantial proportion of the commercial oxygen is continuously blown in through injectors extending through the refractory lining of the vessel and communicating with its interior below the bath surface, where necessary with a protective fluid, desirably surrounding the oxygen. Oscillation of the converter causes the injected gases to sweep back and forth through the bath, and distributes the solids over its surface to provide bath turbulence and interphase contact. Off-gases are desirably recycled. Flexible control means and special apparatus are disclosed.
