Title: Animating device for figure toys
IPC: A63H13/06
Filed: 1974-10-04
Abstract: 1445021 Figure toy animating device MATTEL INC 4 Oct 1974 [26 Dec 1973] 43198/74 Heading A6S A figure toy having rotatable appendages and a torso, e.g. as described in Specification 1331035, is animated by a device 150 including a hand grip 152, having a trigger 156, which is releasably connected to the torso of the figure toy. The hand grip 152 is connected to the torso by means of a waist clamp 160 having pins 210 and 212 which are releasably held by means of thumb screw 214 and threaded plate 215 in bracket 204 pivotally connected by means of pin 162 to hand grip 152 to enable the figure toy to be swung through an arc. Hand grip 152 includes a sleeve 166 rotatable in a barrel portion 158 to enable a lever 164 to be selectively positioned to cause movement of a selected appendage of the figure toy when the lever '164 is moved by squeezing of the trigger 156 acting via lever 180 and push rod 190. Thus in the position shown in Fig. 6 squeezing of the trigger 156 causes the lever 164 to be raised to the position shown in dotted line thereby causing leg 70 to swing in a ballkicking motion. When the sleeve 166 is rotated to place lever 164 in the position shown in Figure 7 (not shown) squeezing of trigger 156 causes lever 164 to inwardly depress a plate 120 in the back of the figure toy to produce via rack 116 and pinion 102 a downwards movement of arm (82), Figure 1 (not shown), simulating e.g. karate chop. In the position shown in Figure 8 (not shown), squeezing of trigger 156 causes lateral movement of lever 164 to disengage latch (172) causing figure toy to swing in an arc about pivot pin 162 simulating e.g. a baseball batter. In the embodiment of Fig. 12, lever 164A is integral with trigger 156A for depressing plate 120 in the back of the figure toy to cause movement of arm (82). A separate lever 164B for causing movement of leg 70 is acted on by spring 217 which also acts on waist clamp 160A and encompasses pivot pin 162A. In this embodiment it is necessary to cook either leg-swinging lever 164B or waist clamp 160A agains.t force of spring 217. Thus if lever 164B is first cooked on squeezing trigger 156A lever 164B, having been held by ledge 218 on trigger 156A, is released to cause kicking motion of leg 70 and on further squeezing of trigger to inwardly depress plate 120 by means of lever 164A to cause arm movement as above. If however waist band 160A is cocked, on squeezing trigger 156A finger 223 is released from waist band 160A to cause figure toy to pivot about pin 162A under effect of spring 217.

Fluid passages (90, Fig. 2) between the control valve and the actuator are continued in a bifurcated member 10. Specification 1023232 is referred to.

Title: Frequency modulation receiver
IPC: H03G5/26
Filed: 1959-12-29
Abstract: 903,107. Automatic selectivity control; muting. DAY, J. R. Dec. 29, 1959, No. 44126/59. Class 40 (5). In a frequency modulation receiver the normally wide I.F. bandwidth is automatically reduced whenever the signal to noise ratio falls to an unsatisfactorily low level. The normal wideband I.F. channel comprises wideband filter 14, limiting amplifier 16, detector 18 and cathode-follower output stage T1 feeding into load R4. A narrow-band channel, comprising narrow-band filter 26, limiting amplifier 28, detector 30 and cathode-follower output stage T2 also feeding into load R4 is branched-off after filter 14. Noise lying outside the useful signal frequency range is selected from the output of detector 18 by band-pass filter 22, is rectified by rectifier V1 and is applied over resistor R1 to the grid of valve T1 as a D.C. bias which cuts-off the valve when the signal to noise ratio becomes poor. The valve T2 is so biased via potentiometer 34 as to become conductive when the current through the common load resistor R4 from valve T1 ceases. The narrow-band filter 26 may be of automatically variable bandwidth controlled by the voltage across resistor R3 (Fig. 2, not shown); in the extreme case it may cut off and produce muting at low signal levels. The arrangement may be used in a diversity receiver, the outputs from a number of receivers such as that described being combined in a combiner element 40, to which the output of rectifier V1 is also fed via lead 41. The Specification also describes a modification (Fig. 3, not shown), in which the channel control valves T1, T2 comprise pentodes working at intermediate frequency, immediately subsequent to the band filters, followed by a common limiting amplifier and detector. Specification 792,124 is referred to.

Abstract: 1396104 Signalling by D.C. POST OFFICE 27 Sept 1972 [27 Sept 1971] 44941/71 Heading H4P In an apparatus for sampling a digital signal having a portion subjected to deliberate mutilation at a determined time, the signal is sampled on or after its centre point at a time dependent on the occurrence of mutilation so as to detect the maximum amplitude of the pulse. The arrangement may be used in a system having two-way communication over a single channel, the duration of transmitted pulses being short compared with the interval between them and received signals are mutilated for the duration of each transmitted signal. Incoming bipolar signals after amplification are converted to unipolar at 3 which synchronize a clock 4 and a hold circuit 6 which distorts signals applied thereto by holding the amplitude constant for durations determined by signals applied to a terminal 5. These are also applied to a NAND gate 12 receiving signals from clock 9 and monostable multivibrator 11 through NOR gate 10 and giving an output to a second NAND gate 13 also receiving inverted clock pulses. Output sampling pulses 8 are applied to a single bit shifting register 15 the outputs from which are connected to gates 16 receiving simultaneously distorted pulses and giving outputs to storage devices 17 which are interrogated and cleared sequentially, by gates 18, to terminal 19 under the control of single bit shift register 20 cycled by pulses at terminal 21. The aligner 15-20 is of known form. The gate 16 or store 17 may include threshold devices so that store 17 may be of binary form. If incoming signals are unipolar converter 3 may be omitted.

Both the reactance and resistance of a variable-capacitance diode 31 shunting part of the frequency determining circuit 12, 14, 16, 17 of an oscillator are varied by a modulating signal at 32 to produce linear frequency modulation over a wide modulating signal bandwidth. Back bias is partly self-produced on the diode 31 by its rectifying action during portions of an oscillation cycle when it is conducting, the portions being determined by an additional fixed back bias from potentiometer 48. The diode resistance is in series with a capacitor 41 across the Colpitts oscillator tuned circuit, which is series tuned by inductor 12. The oscillator output may be mixed with a reference frequency 64 to produce an output actuating a Schmitt trigger circuit 72, whose output, amplified by a wide band amplifier 74, is then limited and detected and through a D.C. amplifier 79 controls a variable capacitance diode 61 in series with a D.C. blocking capacitor 62 shunting the oscillator circuit capacitor 17, producing AFC of the mean frequency.
