Patent GB-1256950-A (GB)
IPC: H03K3/356
Filed: 1969-09-10
Abstract: 1,256,950. Transistor pulse circuits. RCA CORPORATION. 10 Sept., 1969 [17 Sept., 1968], No. 44760/69. Heading H3T. [Also in Division G4] A divider consists of two invertors such as F.E.T.'s 12, 22, a first gate or switch 40 such as F.E.T.'s 42, 44 connecting the output of F.E.T. 12 to the input of F.E.T. 22 and a second gate or switch 30 such as F.E.T.'s 32, 34 connecting the two inputs of F.E.T.'s 12, 22; the input and output voltages being stored during changeover on CA, CB. The switches are enabled alternately. The F.E.T.'s 42, 44 are parallel connected complementary types and are controlled respectively by the clock pulses CP and their complement CP, so that they turn on and off together and eliminate any threshold voltage drop which would arise if only one were used, operating in source follower mode. Similarly, F.E.T.'s 32, 34 operate together, but they are out of phase with F.E.T.'s 42, 44. Preferably the drains of F.E.T.'s 12, 22 a re connected through further F.E.T.'s 14, 24 to the positive supply, 50. When gate 40 is opened by a positive clock pulse CP (and a negative CP), the gate and output line CP1 capacitances C A  are charged to the positive supply voltage through F.E.T. 14 provided the voltage on the gate capacitance of F.E.T. 12, C B , is zero. When the clock pulse changes level (Fig. 2, not shown) gate 40 closes and gate 30 opens so that C B  is charged from C A , the latter being larger than C B  so that its voltage does not drop too much during charging of C A . When the next clock pulse occurs and C P  is positive, F.E.T. 12 being turned on by the positive charge on its gate, and its drain thus dropping towards zero, this zero level is transmitted through gate 40 to F.E.T. 22 which is turned off. Thus a square wave CP1 appears at the output having half the frequency of the clock pulses. In an alternative form (Fig. 3, not shown), the drains of F.E.T.'s 14, 15 are connected individually to the corresponding source electrodes of the F.E.T.'s (42a, 44a) in the first gate (40a).

Abstract: 1297228 Exhaust silencer L F BLATT 27 July 1971 35146/71 Heading F1B Exhaust silencer, particularly for the air valve outlets on air-operated tools e.g. pneumatic presses comprises a cylindrical housing 12 the ends of which are closed by caps 14 and 20 secured by tie-rods 26. The cap 20 has an opening to receive an air exhaust pipe 34 and the cap 14 has an aperture which receives a barrel 40 having an enlarged end 44 which slides in the bore of the housing, creating an annular chamber 46 between the housing and the barrel. A port 70 in the cap 14 communicates with the chamber 46. The end 41 of the barrel adjacent the enlargement 44 fits over a hub 21 projecting from the end cap 20. There are holes 68 through the housing wall which communicate with the annular space 66 between the housing and the barrel. Clamped in the mouth of the barrel, by a ring 64 are two dome-shaped frequency distorter members 52, 54 which are made of sintered bronze or ceramic. In normal operation air exhausted from the tool enters the silencer from the tube 34 and permeates through the member 52 and then out to atmosphere through the member 54. If the members become clogged then the excessive pressure drives the barrel forward and the air escapes through the holes 68. The barrel is biased to the position shown in Fig. 1 by pressure air admitted through the port 70, or by a compression spring which abuts the cap 14 and the side of the enlargement 44 facing the cap 14. Alternatively the barrel may be retained by plastics shear pins. In a modification the holes 68 are replaced by a port (50), Figs.4 and 5 (not shown), in the wall of the barrel, the port being positioned so that when the barrel is retracted the port opens into the annular chamber 46 and when the barrel is driven forward, the port is outside the housing and communicates with atmosphere. The interiors of the members 52 or 54 may be separated by a piece of urethane foam.

Abstract: 1311222 Electric correspondence control systems PENTACON DRESDEN KAMERA-UND KINOWERKE V E B 20 May 1971 16072/71 Heading G1N [Also in Division G2] The objective lens 1 of a microfilm camera has a ring electrode 2 which forms, with a similar ring electrode 4 at a fixed distance from the film plane 3, a variable ring condenser whose capacitance varies with the distance between the lens and plane 3. The condenser is part of a circuit which alters this distance appropriately as the format is changed. As shown in Fig.2, the condenser 2, 4 forms, with a coil 7 and another condenser 8, a capacitance bridge. In the diagonal branch of the bridge is an amplifier 9 which controls the position of a switch 15 in circuit with a motor 16. In the focused position the capacitances of condensers 2, 4 and 8 are equal, so that no voltage exists in the diagonal branch and the motor remains stationary. When the format is altered, the value of condenser B is altered, e.g. by replacing with another condenser. This value is greater or less than that of sondenser 2, 4, so that the switch 15 is thrown one way or the other. Thus the motor is energized to drive the lens 1 and electrode 2 one way or the other until the capacitances are equal once more. The lens is now in the new focused position. In the alternative circuit arrangement of, Fig.3, (not shown), the condenser 2, 4 and a coil (17) form a self-energizing oscillator, and the deviation from a predetermined frequency is utilized to actuate the motor switch 15.

Abstract: 1343892 Testing fluid specimens CALBIOCHEM 3 Feb 1971 3830/71 Heading G1A In an apparatus determining the optical density of a fluid specimen, light passing through a specimen is received by a photo-resistor connected in a bridge circuit whose output has a semi-conductor connected across it. The photoresistor and semi-conductor provide first and second order compensation for the non-linear character of the received light and ensure a linear output signal representing the optical density. Light passing through the specimen is received by a photo-cell 20 in a bridge circuit 112, Fig.2, which contains a variable resistor 30 used for balancing the bridge initially with the aid of a blank specimen. A secondary winding 110 of a transformer 104 provides a voltage across the bridge 112 and a silicon controlled rectifier 116 is connected in the output of the bridge 112, the semi-conductor rectifier being connected to the centre of a secondary 108. When in use, the bridge becomes unbalanced and its output effects the current passing through the silicon controlled rectifier which in turn affects the current passing through a meter 22, since the signal passing through the meter will have an A.C. component an integrating capacitor 128 is employed so that the output current of the meter 22 is the D.C. average.

Title: Method and apparatus for bifurcating signal transmission over in-phase and quadrature phase spread spectrum communication channels
IPC: H04J13/00
Filed: 1994-10-30
Abstract: An improved system and method for communicating information over in-phase (I) and quadrature phase (Q) communication channels in a spread spectrum communication system is disclosed herein. In an exemplary implementation, first and second information signals are respectively transmitted over the I and Q communication channels using direct sequence spread spectrum communication signals. In-phase pseudorandom noise (PNI) and quadrature phase pseudorandom noise (PNQ) signals of predetermined PN codes are used for spreading the first and second information signals, respectively. In particular, the PNI and PNQ signals are respectively combined with the first and second information signals and an orthogonal function signal to provide I-channel and Q-channel modulation signals. The I-channel and Q-channel modulation signals are used for modulating in-phase (I) and quadrature phase (Q) carrier signals for transmission to a receiver via the I and Q communication channels, respectively. In a preferred implementation the receiver is operative to produce an estimate of at least the first information signal on the basis of the I-channel and Q-channel modulated carrier signals received over the I and Q communication channels. The received I-channel and Q-channel modulated carrier signals are demodulated and despread, with the resultant sequences being correlated into in-phase (I) and quadrature phase (Q) projection signals. A phase rotator operates to provide an estimate of at least the first information signal based on the I and Q projection signals and a received pilot signal.
