Title: Movable toy
IPC: A63H29/18
Filed: 1968-11-22
Abstract: 1,247,169. Drive for toy vehicle. E. A. BETTAG [trading as BIG SPIELWARENFABRIK DIPL-ING ERNST. A. BETTAG and H. BROSS], 22 Nov., 1968 [22 Nov., 1967], No. 55498/68. Heading A6S. A toy, see for Example Fig. 4, vehicle comprises a drive shaft, 3, and a one way clutch, 2, acting, in one rotational direction only, to connect the drive shaft with the rotary member, 21, which is rotatably mounted on the drive shaft and to which is fixed a resiliently extensible cord 7, the other end. of the cord being fixed to the housing by the anchor, 9; such that during the winding on of the cord and during the drive phase this connection is made but that when the cord has been unwound from the drive shaft 3, at the end of the drive phase, the clutch disengages and the drive shaft is then able to continue to rotate. The member 21, is resiliently urged into the interengaging position with the coupling member 20, of the drive shaft by the oblique mounting of the cord 7. Indentations may be formed in the oppositely facing radial end faces of the coupling member and the rotary member to accommodate a helical spring surrounding the drive shaft (Fig. 6 not shown), a stop on the drive shaft preventing excess axial displacement of the rotary member. In order to prevent the elongation, beyond the proportionality limit, of the resilient cord, the abutment, 8, engages with the housing mounted stop, 24, when tension in the cord reaches a given value. Alternatively (Figs. 2, 5 not shown) a disengaging means may operate when this tension is reached. The rotary member may be mounted in bearings on the housing or alternatively the drive shaft may be thus mounted. The one way cltuch may comprise a spirally arcuate spring (15), included in the rotary member and a radial projection engageable with one end of the spring during rotation of the drive shaft, the spring flexing axially when relative movement occurs in the opposite direction to permit freewheeling. The rotary member 21, is mounted centrally of the drive shaft, which bends when the drive cord reaches the given tension. Alternatively the rotary member moves as a whole, transversely of its length, when the tension reaches the given value, resilient split bearings being provided. Figures 7 and 8 (not shown) show means whereby the drive wheels are engagable with the rotary member via a bevel wheel and gear wheels coaxial with the drive shaft and rotary member or via a retractable surface wheel and gear wheels thereon and on the rotary member; this means coming into operation when the vehicle housing is pressed down, the gearing being such that winding of the drive cord may be achieved by pushing the car in a forward direction. The gear wheels and retractable surface wheel are of such a size as to require less movement of the vehicle during the winding on stage than that produced during the drive phase. Flanges 13, guides 25, or stops 26, are provided to limit the surface over which the cord is wound on.

Abstract: 1,167,320. Control of A.C. motors; inverting. STANDARD TELEPHONES & CABLES Ltd. 30 Dec., 1966, No. 58355/66. Headings H2F and H2J. [Also in Division H3] The speed of an induction motor is controlled by energizing its stator via two gate turn-off devices GTO1, GTO2 controlled by a generator of square waves whose pulse width is modulated sinusoidally by a frequency-controlled oscillator so that the net stator flux A also varies sinusoidally. As shown, the motor has bifilar stator windings X, Y which are energized alternately but a standard motor may be used, its stator being connected to the secondary of a transformer whose primary has the windings X and Y. The pulse generator comprises a free-running multivibrator circuit (Fig. 3, not shown) and the oscillator is a Wein bridge oscillator (Fig. 2, not shown) whose output is amplified by bi-stable switching circuits (Fig. 4, not shown). The switching devices GTO1, GTO2 are protected by ensuring good coupling between X and Y, so that stored energy is transferred at change over, diodes D5, D6 completing the circuit. If triggering pulses are short R25, D3 and R26, D4 provide "hold-on" current. For polyphase motors a single oscillator would modulate the required number of channels. The supply may be either smooth D.C. or unsmoothed full-wave rectified A.C.

Filed: 1972-12-30
Abstract: 1415319 Variable resistors MATSUSHITA ELECTRONIC INDUSTRIAL CO Ltd 30 Dec 1972 60271/72 Heading HIS At least four separate variable resistors for use in, e.g. a quadraphonic reproducing system, may be controlled by a single pivoted shaft which on rotation about its own longitudinal axis may control a further plurality of ganged variable resistors. A pair of variable resistors 4, 5 are coaxially mounted on the opposing outer walls 1a, 1b of frame 1, and their shafts 2 and 3 extend inwardly. An inner frame 10 is mounted on the shafts 2, 3 for rotation in unison therewith. A second pair of variable resistors 15, 16 are mounted in opposition on the remaining pair of walls 10e and 10d of inner rectangular frame 10, and are coupled to a connecting member 21 on which is mounted a bearing which supports operating shaft 23. A series of ganged variable resistors are mounted on shaft 31 which is connected to operating shaft 23 by a universal coupling comprising yoke member 32, shaft 25 extending through a slot (24) formed at the lower end of shaft 23, and secured thereto by a pin (26). When shaft 23 is tilted, in any direction, the values of all the resistors 4, 5, 15, 16 are altered, since shaft 23 rotates both about the axis formed by shafts 2, 3 and the axis through 13, 14. Additionally rotation of shaft 23 about its own axis, in any position, alters the value of resistance in each of ganged resistors 27-30. The assembly may therefore be used as a combined 4 channel balance and volume control.

Filed: 1970-12-23
Abstract: 1340209 Electron microscopes NIHON DENSHI KK 23 Dec 1970 [25 Dec 1969] 61282/70 Heading H1D In an electron microscope provided with two sets of deflecting means for deflecting the beam off the axis and back again in order to vary the angle of incidence of the beam on the specimen to observe a dark field image and a diffraction pattern, the point of incidence may vary as the angle is varied due to the deflecting coils in one set not being positioned accurately orthogonal to each other and parallel to those of the other set. This is obviated by feeding each coil with at least two uni-directional current components which are independently adjustable. In one example the coils deflecting the beam off the axis are each fed with three components for adjusting the deflection, for compensating for positional errors, and for aligning the beam, whilst the coils returning the beam to the axis are supplied with two components. The separate components may be derived from potentiometers which may be manually adjustable, and the controls of different coils may be coupled together to effect dependent adjustments in predetermined manner. The outputs of the potentiometers may be fed through individual resistors to the input of a summing amplifier feeding the coil directly (Fig. 2, not shown) or through a transistor output circuit (Fig. 3, not shown). Alternatively the potentiometers may be connected to individual amplifiers, the outputs of which are summed (Figs. 4 and 5, not shown).

Oct. 21, 1948. [Feb. 27, 1948] No. 27362/48. Class 9 (i). [Also in Group XXXVIII] Apparatus for seismic exploration is provided with a shaped charge, means for exploding the charge above the earth's surface so that the jet produced thereby is horizontal, and means for receiving the resulting seismic impulse after its passage through submerged strata. Fig. 3 shows a charge 20 having opposed conical cavities 21, 22 to produce jets 24, 25. Each cavity has a metal lining 13 and the included angle of the cone is 45 degrees. The axes of the cavities are inclined at an angle A equal to twice the Mach angle B/2 for the shock waves produced by the jets, so that on firing the charge above ground level the shock wave fronts travelling downwardly are inclined towards each other (Fig. 4) and on reflection from a submerged stratum are received simultaneously at a geophone G. In a modification the charge 48 (Fig. 7) is disc-shaped and has a peripheral groove of V-section, an electrically initiated blasting cap 54 being placed in an axial recess 55. The groove is so orientated that the resultant jet 52 is directed downwardly at an angle A to the horizontal, the resultant shock wave 56 being incident at the earth's surface over a large area. To eliminate the blast wave front 59 extending from the body of the charge, a shield 64 (Fig. 9) is placed beneath the charge. This shield is a steel plate, # inches or more thick. Additional shielding material such as water or sand may be placed in a container 66 below the plate. In a further modification, Fig. 10a, a disc-shaped charge 69 with a peripheral groove 70 has its sides 71, 72 dished to form frusto-conical depressions into which fit containers 79, 81 of laminated paper or sheet steel, filled with damp sand, a baseboard 78 of compressed fibre being arranged below the device. The high explosive may be TNT or RDX. When the first form of the device (Fig. 3) is fired 5 feet or more above the ground the wave front reaching the earth is about 1 foot wide and 200 feet long.
