Abstract: 1481031 Centrifugal and axial-flow compressors HOWELL INSTRUMENTS Inc 21 Oct 1974 [23 Oct 1973] 45470/74 Heading F1C A probe 14, Fig. 2, mounted downstream of an axial-flow or centrifugal compressor stage senses flow reversal of the boundary layer when surge is imminent. An associated detector 16 can be arranged to give a warning signal or to open a valve 18 to permit some of the boundary layer to return to the inlet side of the stage. Alternatively, the detector is arranged to open a valve which allows the fluid to by-pass the compressor or allows the high-pressures at the outlet side to be relieved to atmosphere. The probe comprises a tube with a radial hole (32), Fig. 4 (not shown), at its sensing end directed downstream so that normal flow creates a suction effect within the tube and flow reversal creates a positive pressure. The detector may be a mercury manometer.

Title: Controller for process control apparatus
IPC: G05B11/42
Filed: 1972-10-04
Abstract: 1401835 Automatic control systems VAPOUR CORP 4 Oct 1972 [22 Oct 1971] 45719/72 Heading G3R In a process controller in which an actuator moves at a single speed for a time depending upon the magnitude of an error signal in a system requiring position feedback from the actuator, this feedback is provided by integrating the voltage from a Schmitt trigger which energizes the actuator, thereby producing a ramp voltage equivalent to that which would be obtained from a position transducer. As shown, a process error signal ep is derived at comparator 14 and is amplified in a proportional plus integral amplifier 15, the output Vo of which is applied to Schmitt trigger 20 which determines the limits of error. The output Vo is opposed by the rising feedback voltage from an integrater 21 so that when these are substantially equal the trigger turns off. In alternative embodiments the amplifier 15  has proportional action only and an approximation to integral is provided by causing the integrator 21 to gradully reset after the trigger is turned off so that while an error signal remains the actuator is repeatedly operated for short periods. In Fig. 5 (not shown) this is effected by connecting a resistor across the integrating capacitor CT; in Fig. 6 (not shown) the amplifier output is inverted and fed to the input of the integrator when the trigger is off via a solid state switch. In Fig. 7 (not shown) a resistor across capacitor CT is connected through a transistor which is turned on by a logic device when the trigger is off. The actuator may comprise an electromagnetic valve 11 and hydraulic cylinder 10 or a reversible electric motor.

Abstract: 1410997 Article dispensing apparatus CAPTAIN INTERNATIONAL INDUSTRIES Ltd 5 Oct 1972 [21 Jan 1972] 46001/72 Heading A4T Article dispensing compartments, in groups of two, as shown in Fig. 1, closed by gates 13a, 13b, 20a, 20b unlatched for manual opening about axis 15 one at a time by depressing knob 53 which at the same time sends an electric signal to a cashiers desk indicating the extraction of an article e.g. in a hotel room, has the gates latched by a cross-bar extension e.g. 18a entering an opening 25, in side wall plate 22 and being caught in a U-bracket 33, or 34 on a plate 31a as seen in Figs. 2, 3 with plate projection 38, Fig. 2 resting on top of leaf 48 rotatable on rod 46 between legs of U-member 49 and resting on rod 52 carrying knob 53. When knob 53 is depressed against spring 54 between washer 55 and arm 67 of U-member 50 on rod 46, rod 46 moves to the right until U-arm 67 abuts edge 66 of spring hinge 60 pivoted at 61. On further pushing knob 53, rod 52 slides through the U-arms to engage cam 65 and deflect the hinge 66 away from arm 67 so that knob 53 snaps in and shifts rod 46 and leaf 48 to the right. Plate 31a falls until a plate projection 40 rests on leaf 48 and on release of knob 53, spring 68 shifts both rods leftwards so that projection 37 rests on leaf 48 and channel 33 falls below bar 18a and allows the gate 13a to be opened. Further operation of knob 53 allows plate 31a to fall in two steps between projections 37, 39 and 36 to remove channel 34, Fig. 2 from latch bar 18b allowing the second gate 13b to be opened. Rod 46 passes through side wall plate 45 and is bent downwardly to a pivot 85, Fig. 2 and engages rod 80. When master switch 113 is closed, a solenoid 109 lifts rod 80 away from stop 102 so that rightward movement of rods 46, 80 actuates micro-switch 106 sending a signal that a compartment is opened. The two lower compartments 20a, 20b are unlatched one at a time by a knob 53 acting on rod 70, Fig.2 engaging rod 82 pivoted at 84 and engaging a parallel rod 81 for a micro-switch 106. A locking rod (90), Fig. 5 (not shown) between rods 80, 81 ensures only one compartment and switch is actuated at a time. When both compartments have been opened, engagement of leaf 48 with projection 39 prevents further depression of knob 53. In the embodiment of Fig. 8, after closure of master switch 152, depression of switch button 150 allows solenoid 148 to pull U-rod 140 to the right through side wall bracket 130 against spring 145 thus displacing leaf 48 and allowing plate 31a to fall under spring 155 and unlatch a gate. U-arm 143 actuates signal micro-switch 135. To indicate a gate has been unlatched, a weight 121 pivoted at 120, Fig. 1, swings downwards and acts on gate pin 19 to project the gate into a forward position.

In a connector the contact terminals are locked into a bore in an insulating body, after insertion from the rear, by a fixed stop preventing further forward motion and an adjustable stop which normally prevents rearward withdrawal but which may be released by the insertion of a tool in an access passage at the rear. As shown, the bore in the insulating body 11, Fig. 2, is lined with a resilient split sleeve 35, Fig. 7, part of which is formed into a tongue 41. The contact terminal, in this ease a pin, is inserted from the rear and the collar 27 raises tongue 41 until the collar passes the end of the tongue and beds against a fixed shoulder 39. The tongue then springs back and prevents the terminal from being withdrawn. The terminal may be removed by inserting a tool into the slot at the rear between the terminal and the sleeve, which raises the tongue 41 and allows the rearward withdrawal of the pin. In further embodiments are described a slave with two locking tongues, arrangements in which the terminal may be a socket, and shortened sleeves. The insulating body may be made of hard material or of relatively soft elastomeric material stiffened by the sleeves, which may be made of metal or a synthetic resin and may be sprung into the insulator, bonded by a suitable material or held in place by insulating face plates.

Filed: 1962-12-07
Abstract: 1,012,973. Automatic voltage control systems. FERNSEH G.m.b.H. Dec 7, 1962 [Dec 7, 1961], No. 46244/62. Heading G3R. An automatic voltage control system comprises a transformer 3 and a rectifier 4 for developing an unstabilized direct voltage which is fed to a load circuit 7, 8 by way of a triggered rectifier device 5, prefereably a silicon controlled rectifier the triggering pulses for which are dependent upon a sawtooth waveform superimposed upon a direct voltage which is a measure of the load voltage. A voltage representative of the load voltage is developed by means of a potential divider having resistors 21, 22, 23 and a Zener diode 15, this voltage being applied to the base of a transistor 18 together with, by way of a capacitor 17, a sawtooth voltage developed from the voltage across the Zener diode 15 by a circuit including a resistor 11 a diode 12 and a capacitor 13. The time at which the transistor 18 becomes conductive is thus dependent upon the magnitude of the voltage upon which the sawtooth is superimposed and when transistor 18 becomes conductive it causes a signal to be applied to the base of the transistor 31 causing it to conduct and so apply a triggering pulse to the rectifying device 5 which is thereupon rendered conductive and is effective to correct any tendency for the load voltage to fluctuate. A diode shunted inductor 33 may be connected in series with the rectifier 4 to reduce the power dissipation in the triggered rectifier device 5. In a further embodiment a second triggered rectifier device is connected in parallel with the device 5, controlled in a similar manner to the device 5 but is controlled to become conductive earlier than the device 5.
