Title: Dancing walking doll
IPC: A63H13/04
Filed: 1969-07-22
Abstract: 1,249,579. Dancing, walking figures; dolls. MATTEL Inc. 22 July, 1969 [2 June, 1969], No. 36812/69. Heading A6S. In an electrically operated dancing, walking doll, the legs 27, 28 are pivoted on the torso 17, and are caused to swing back and forth in a walking motion, by leg support members 314, 318 whose ends 316 act on cams 312 driven by the motor 25. A wheel 220, also driven by the motor, has a ball 222 attached to its circumference, said ball being engaged in a slot 306 of a torso bracket 300, so that when wheel 220 revolves, the torso rocks from side to side. When the motor revolves in one direction the rocking of the torso is such that the movement of the legs causes the figure to walk forwards, i.e. each leg supports the torso when the leg is pivoting backwards. On reversal of the motor direction, due to "backlash" in the drive couplings, the torso during its rocking motions, is supported by each leg and sometimes both legs, during substantial amounts of both their forward and backward pivoting, so that the figure does not walk forwards or backwards, but executes dancing motions. A crank 105 connects lugs 113 on the drive unit,  to a transverse member 95 which causes swing- ing of the arms and pivoting of the head from side to side, in synchronization with the leg movements and the torso rocking motions. The doll can also be adapted to have no backlash when the drive motor is reversed, so that it does walk backwards in a similar manner to it walks forwards.

Title: High Density and/or High Frequency Digital Recording
IPC: G11B20/10
Filed: 1967-08-10
Abstract: 1,177,774. Digital data storage. AUSTRALIA, DEPARTMENT OF SUPPLY, SECRETARY OF. 10 Aug., 1967 [11 Aug., 1966], No. 36840/67. Heading G4C. High density recording on magnetic tape is achieved without increasing the risk of errors being caused by drop-outs or tape skew, groups of N bits being recorded simultaneously on the same track over a length not greater than that required by N bits recorded serially. In a first method groups of N parallel bits frequency modulate N equally spaced carrier frequencies. In a second method, N carrier frequencies are phase-reversal modulated, a pilot reference tone being simultaneously recorded, so that on playback the carriers may be phase-locked to the reference tone. In a third method, bits represented by positive and negative pulses are applied serially to a dispersive filter whose group delay is a function of frequency such that the output signal corresponding to each bit has a duration N times that of the original bit. At any instant the output of the filter contains frequency components of N successive bits, and this signal is passed through an amplitude equalizing network having an amplitude response which is the inverse of the signal : noise power density of the recording system before recording. Playback requires an amplitude equalizing network and filter having inverse characteristics to those used in recording.

Abstract: 1,001,641. Protective arrangements; control of motors; electrically released switches; electromagnetic relays. M. CLAUSEN, [trading as FIRMA DANFOSS VED ING. M. CLAUSEN]. Oct. 16, 1961 [Oct. 19, 1960], No. 37040/61. Headings H2B, H2K and H2J. In a protective arrangement for an electric motor driven apparatus, comprising a switch 7 responsive to a defect occurring in the apparatus and connected in circuit with a current responsive delay element 3 of a safety switch effective to cause disconnection of the motor, interruption of the current through the delay element causes the operation or release of a relay 9 to disconnect or effect the disconnection of the motor. Fig. 3 shows a circuit in which the safety switch and relay are combined and have a single set of contacts 4. The delay element 3 and the relay 9 are connected in series with resistors 5, 6 with the relay 9 normally being sufficiently energized through these resistors to maintain the contacts 4 in the position shown. When the defect occurs, the switch 7 closes and the resulting increased current causes the element 3 to release the contacts 4 into the position in which they complete a circuit for a motor control relay 8. Fig. 4 shows the construction of the combined relay and safety switch, the delay element 3 comprising a bimetallic element 17 with heating coil 18. The element 17 normally latches a spring-biased lever 26 in the position shown so that contacts 21, 25 are closed, providing the coil 11 of the relay 9 is energized and holds an armature 13 in the position shown against the bias of a spring 14. When the current in the heating coil 18 increases, the bimetallic element 17 releases the lever 26 to open the contacts 21, 25 and close contacts 25, 22. Alternatively, interruption of the current in the coil 11 causes the release of the armature 13 which falls on to the moving contact-carrying member causing it to pivot at 30 on the lever 26 to change over the contacts. In other arrangements the safety switch and relay are individual devices, the relay coil being connected in series with or in shunt with the delay element. The apparatus protected may be a compressor with the switch 7 being a pressure-responsive switch operative on failure of the lubrication pressure in the compressor.

Abstract: 1,199,009. Making combustible gas. GAS COUNCIL. 17 July, 1968 [15 Aug., 1967], No. 37530/67. Heading C5E. [Also in Division C1] A process for making a gas containing gaseous hydrocarbons by hydrogenating a hydrocarbon oil comprises preheating the oil e.g. to 300 to 400 C., in the liquid phase and atomizing the oil into a gas recycle hydrogenator where the oil reacts under pressure with, and is entrained into circulation with, a supply of hydrogenating gas. The process is intended for non- distillate oils, e.g. crude petroleum, but distillate oils may be used, in which case the atomizer may be replaced by a pipe or jet. Atomization may be by the hydrogenating gas, which may be pre-heated, using conventional atomizing apparatus, and all the hydrogenating gas may be supplied in this way, although some may be delivered through an outer tube coaxial with the atomizer, and a small proportion may be introduced into the oil before pre-heating. Air may be added to the reactants to provide heat, and steam to mitigate carbon deposition. Operating temperatures in the range 650 to 850 C., and pressures in the range 5 to 100 atmospheres are mentioned.

Abstract: 1,024,796. Coating apparatus. METAL BOX CO. Ltd. Sept. 14, 1964 [Sept. 25, 1963], No. 37769/63. Heading B2B. [Also in Division G1] In apparatus for applying material to an area of an article and to detect any discontinuity in the material applied, the articles e.g. carton blanks are moved in succession by endless belts 2 past an adhesive applicator wheel 3 against which a carton flap is pressed by spring-loaded wheel 6. The blank is subsequently passed through apparatus for forming it into a carton. The adhesive coated areas are scanned by photo electric means comprising basically of lamp 20 and a photo multiplier 11 (Fig. 4) which is electrically connected via line 12 with a fault registering device 13. The latter is controlled by the sensing of leading and trailing edges of a blank by photo-electric cell 23 via line 26 so that the fault-registering device 13 is conditioned to receive fault-indicating signals whilst the blank is interposed between light 24 and cell 23 and when the trailing edge passes cell 23 the device 13 transmits an actuating signal along line 27 to fault indicating device 28 if a fault has been sensed. The device 13 may pass corresponding signals to audible and visual fault indicating devices 31 and 32. The fault indicating device 28 comprises an electronic shift register consisting of register units 34 connected in series. A driver circuit 35 is connected to unit 28 by line 36 and is arranged to produce a succession of shift pulses to transfer an actuating signal in succession from one unit 34 to the next. The driver circuit 35 is operated in synchronism with conveyer 7 which is transmitting the blanks received from the adhesive application device by means of disc device 38 in conjunction with lamp 41 and equi-spaced radial light reflecting elements 39 and photoelectric cell 42. The arrangement is such that when a fault indicating signal has been entered on the shift register 28 and reaches the last unit thereof the blank has travelled a definite predetermined distance along the machine and is positioned before a solenoid operated pulse element controlled from the switching means 44 and the actuating device 46 such that a carton which has been found to be faulty by the photomultiplier 11 is displaced from the line of carton blanks. The photo-multiplier 11 detects faults in the coating applied and also the absence of blanks.
