Title: Improvements in diode gate circuits
Inventor: BILOTTI ALBERTO
IPC: H03K3/33
Filed: 1965-04-13
Abstract: 1,108,671. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. 13 April, 1965 [13 April, 1964 (2)], No. 15606/65. Heading G4H. [Also in Division H3] In a switching circuit having a diode D connected in series with an alternating voltage signal source G and a load ch, the diode is either forward or reverse biased by a biasing means, e.g. transistor T so that when the peak voltage of the alternating voltage signal is greater than an applied forward bias voltage and because the period of oscillation of the signal source G is less than the charge storage time of the diode the diode conducts linearly for each cycle of the signal to transmit the signal to the load substantially without distortion, whereas when the reverse bias is applied the signal is not transmitted. Two circuits may be arranged in series with the diodes back-toback so that both diodes have to be biased on for an output to occur in the load (Rij, Fig. 4, not shown). The second diode is biased by a transistor of complementary type to that used for controlling the first diode. This form of circuit may be used in an array of switching circuits (Fig. 3, not shown), in which m switching circuits, e.g. Dlo-Dio-Dmo, are connected in parallel to the signal source G and in which n switching circuits, e.g. Dll, Dlj, Dln, are connected in parallel to each of the m switching circuits. The loads, e.g. Rmn, Rij, Rll, are each connected to the signal source via two back toback connected diodes (Dmn, Dmo) when they are both biased on.

Title: Improvements in systems for controlling sliding glass panes
IPC: E05C17/62
Filed: 1958-05-16
Abstract: 847,309. Window holders. ETABLISSEMENTS G. KLEIN & CIE. May 16, 1958 [May 18, 1957], No. 15742/58. Class 44. In a system for holding a vertically slidable window pane 1 in the desired position relative to its fixed frame, locking devices 6 at each side of the window are controlled by means which, after having been actuated to effect the release of the devices 6, ensures, after a given time interval, during which time the pane can be re-adjusted to a new position, automatic return of the devices 6 to the locking position. Each device 6 includes a lever 8 pivoted at its ends 9, 16 respectively to a fixed support 10 and a link 12 pivoted at its other end to a bent lever 13 pivoted at 14 to the support 10. The lever 8 carries a spindle 7 which extends through a bar 5 along the adjacent side of the windows. The bars 5 pressing the sides of the. pane against resilient packings 17 carried by the window frame when links 15, interconnecting the pivot points 11 of the corresponding pairs of devices 6 at each side of the window, are retracted into their lowered position as shown in Fig. 4. When the links 15 are raised the spindles 7 carry the clamping bars 5 away from the window to release the latter. Each link 15 is connected through links 18, 19 and a bell-crank lever 20 to a control lever 21 pivoted at 22 to a fixed part of the window. One end of the control lever 21 is pivoted at 28 to the rod of a piston 24 moving in a pivotally-mounted cylinder 25 and biased to the full-stroke position by an energy-storing spring 29. A dash-pot 30, containing liquid and adjoining the cylinder 25 communicates with the latter through a spring- loaded check valve 31 and a calibrated orifice 33. In operation, when the control lever 21 is moved to the right, the links 15, 18 are raised and the bars 5 are moved out of engagement with the pane 1. At the same time the piston 24 compresses the spring 29 while sucking liquid into the cylinder past the valve 31. As soon as the operator releases the control lever 21 the spring 24 urges the piston back at a relatively low speed the valve 31 being closed and the liquid escaping from the cylinder through the orifice 33. During the time between the operation of the lever 21 and its return to its initial position the pane 1 is free to be moved by the operator. The return of the system to its locking position can be accelerated by the inclusion of a by-pass in parallel with the orifice 33. For glass panes having manual control of the lever or handwheel type the locking devices may be operated by the initial displacement of the control. A pane counter-balancing device, such as 4 is optional.

Filed: 1963-04-22
Abstract: 1,034,440. Battery charging systems. SONOTONE CORPORATION. April 22, 1963 [May 7, 1962], No. 15852/63. Heading H2H. A battery charging system has a saturable core oscillator 20 comprising a transformer 23 and transistor 21 providing pulse width modulation of current from a rectifier 17 to a battery 12. When a determined fraction of the battery voltage falls below that of a Zener diode 42, Fig. 2, a sensing circuit 33 removes a bias from a lead 35 allowing the circuit 20 to oscillate. As a result of a shorter time of saturation of transformer 23 with increasing rectifier output voltage, the oscillator 20 provides approximately constant trickle-charging current. Another voltage-sensing means 33-2 responsive to a lower voltage energizes a relay coil 76 energizing through contacts 76AB another relay coil 56, closing contacts 56AB which apply a voltageto-voltage dividing resistors 65, 66, the resistor 65 energizing a time motor 51 through contacts 78CB, 78EF which close contacts 52 BC energizing a relay coil 55 opening contacts 55BC which starts the oscillator and closes contacts 55 DE completing the circuit through diode 38 and resistor R4 across the secondary winding 25 to shorten the off time of the oscillator. When the timer motor has run forward for say three minutes a time cam momentarily closes a switch 53ED energizing relay coil 57, opening contacts 57EF and closing contacts 57AB, 57DE supplying reversed polarity of full voltage to motor 51 which returns to its starting position at a higher speed to control the duration of the topping charge. If the battery reaches the fully charged condition during this period, relay 33-3 terminates the charge. If the battery is still below the full charge voltage, sensing means 33- 2 will start another forward and reverse cycle of the motor 51.

IPC: G01G19/22
Filed: 1954-06-02
Abstract: 779,356. Electric correspondence control systems. SIMON, Ltd., H. April 29, 1955 [June 2, 1954], No. 16294/54. Class 40 (1). [Also in Group XVIII] In a circuit for controlling an automatic feed weigher which batch weighs a number of different constituents in a single weigh pan, resistances R1, R2 form two arms of a bridge, the other two arms of which comprise a potentiometer P operated by movement of the weighing mechanism W and a bank of pre-set resistors CP1-CP8, CR1-CR8 which are connected in the bridge in turn by movement of the wiper of bank 2 in a selector switch. In operation closing of a switch S steps the wipers of banks 1-4 to the second contact and, when due to the weight of the first constituent reaching a predetermined value, the bridge balances, a null voltage amplifier N operates a relay O/4, which opens contacts O1, which by de-energizing relay IF, causes contacts 1fl to open and discontinue the feed of the first constituent by de-energizing the first feed gate operating electromagnet IG. Relay O/4 also closes contacts O2 which over contacts 1gl, which are closed when the associated first gate is closed, causes the wipers to step to the fourth contact where the cycle is repeated for the second and succeeding constituents. When the wipers reach the 24th contacts, a relay D is operated and, over contacts d1, energizes the pan discharge door operating electromagnet B. The subsequent opening of this door changes over contacts b1 so stepping the wipers to the 25th contact which de-energizes electromagnet B whereupon the door closes, contacts b1 are restored and, providing the bucket is empty so that the bridge balances, the wipers step to the first contact for the cycle to be repeated. If, due to faulty operation, the wipers remain on any contact other than the first for a period exceeding the time constant of a circuit C1, C2, R3, R4 an alarm bell B1 and lamp L2 are operated. As shown, resistors CP1-CP8, CR1-CR8 are adjustable but in a modification (Fig. 3, not shown) fixed resistors, the values of which correspond with the proportions of a desired mix, are connected in the control circuit by means of plug-jacks. In another modification (not shown) the different materials may be discharged separately instead of being collected together in a weighing hopper.
