Filed: 1966-12-30
Abstract: 1,115,140. Semi-conductors. STANDARD TELEPHONES & CABLES Ltd. 30 Dec., 1966, No. 58354/66. Heading H1K. A first compound of an impurity to be diffused into a semi-conductor body is caused to react with water vapour to produce a second compound of the impurity, which itself reacts with the semi-conductor surface to deposit the impurity thereon and to produce diffusion into the body. In the embodiment silicon wafers 3 are placed on a quartz jig 4 within a quartz tube 1 in a furnace 2. Nitrogen flows across liquid boron tribromide 5, and carries it along a tube 7 to combine in the tube 1 with a mixture of nitrogen and oxygen introduced at C, and with further nitrogen introduced at B and bubbled through water at room temperature. The boron tribromide is oxidized to boron trioxide, which reacts with the water vapour carried by the nitrogen, to produce metaboric acid HBO 2 . This compound reacts with the silicon surface to deposit boron thereon, which impurity then diffuses into the silicon. The method may also be applied to phosphorusdoping of silicon.

Title: Noise-producing devices for toy vehicles
IPC: A63H17/34
Filed: 1971-12-21
Abstract: 1319927 Toy vehicles W H MULLER [trading as SCHREYER & CO] 21 Dec 1971 [24 Dec 1970] 59258/71 Heading A6S [Also in Division G5] Noise making mechanism simulating engine noise in a toy vehicle comprises an electric motor for driving the mechanism, the circuit of the motor including a switch closed when a door of the vehicle is opened, and there being an adjuster to control the pitch of the noise produced. In the form shown, an electric motor 1 carries a driving friction wheel 3 engaged by a friction disk 8 at right angles to it, to rotate a holder 9 including clappers 11  engaged with a resonant surface 12. The motor 1 is energized by batteries 17 when a door of the toy vehicle is opened to close a switch 13. The motor 1 can be moved at right angles to the disk 8 to vary the gear ratio by a slider 4 moved against the biass of a spring 6: the slider 4 may simulate the accelerator pedal of the toy vehicle, varying the gear ratio changing the speed of rotation of the clapper holder 9 and thus the pitch of the emitted sound. In one modification, the variable ratio gear 3, 8 is omitted, and the motor 1 is instead powered from its batteries through an adjustable resistor (22, 23), Fig. 4 (not shown). In another modification, the door-operated switch is arranged with two contacts, one initially connecting the motor directly to the battery as the door is first opened and the other subsequently connecting the motor through a resistor as the door is further opened, Fig. 5 (not shown). Starting of the motor is thus facillitated. In yet another form, the motor drives the clapper holder at constant speed, and a resonant diaphragm having posts emitting sound of varying pitch is moved relatively to the clapper holder by a slide bar, Fig. 6 (not shown). In a further embodiment, a slide bar carries a contact which is successively engaged with contacts connected through a resistor to a single battery; directly to the single battery; and finally to two batteries in series, to vary the motor speed and hence the pitch of the emitted sound, Fig. 7 (not shown). In a final form, variation in pitch is provided by clappers (11), Fig. 8 (not shown) of two different sizes mounted in the holder, the distance between the clappers and the resonant surface being carried so that some or all of the clappers engage the surface.
Patent GB-595859-A (GB)
Abstract: 595,859. Clock-driven indicators. SEMELS. A. July 11, 1945. No. 17747. Convention date, April 17. [Class 118 (i)] A clock-driven cinema or like programme progress indicator comprises a dial of annular shape, but less than 360 degrees over which by means of a clutch a pointer is driven between two limiting stop elements, one of which is adapted to disengage the clutch. Means are provided for automatically returning the pointer to its start position at the end of its travel and for maintaining the clutch disengaged while this return motion is accomplished. The dial of the device is composed of sectors 17 ... 20 (Fig. 1) bearing descriptions of the features making up a complete cinema or like programme slidably mounted in H-shaped channel members 16. The size of the sectors is proportional to the time occupied by the feature they represent and the members 16 are movable around the top portion of the casing 15. The clock 21 is a normal clock and takes no part in the operation of the indicator. A second clock device 23 (Fig. 6) drives by suitable gears 27, 28 and coupling 63, 64, 44 one disc 36 of a friction clutch 33, the other disc 35 of which drives a pointer 22 over the dial sectors. The pointer thus indicates at 66, Fig. 1, the time a feature has been in progress, and when it reaches the stop element 26<1> (Fig. 4) it depresses this to close switch 26 and supply current to a solenoid 38 (Fig. 6), the armature 38<1> of which is drawn inward and by means of lever 39, pivoted at 40, slides the clutch member 36 out of engagement. The pointer is now returned to the stop member 25<1> by a torsion spring 61 which has been tensioned during the forward movement of the pointer. The clutch would normally be reengaged as soon as the pointer left the stop element 26<1> so the release of the armature 38' drives by means of a pawl 48, ratchet 51, and gears 53, 54 a fly-wheel 58. The starting inertia of the fly-wheel allows time for the pointer to return to its start position before the armature 38<1> can re-engage the clutch. The distance travelled by the pointer 22 can be altered by sliding the stop elements 25<1>, 26<1> vertically within their respective mounting slots 67, 68, and clamping them by means of nuts 71.

According to the invention, two series of coils extend parallel to one another along the path, the current controlling means being so arranged to control the current supplies to the two series of coils, relatively to one another, so that the lateral position or orientation of an article being conveyed along the path can be varied by relative adjustment of two parallel moving magnetic fields. The path of movement of the object 4 is defined by a magnetic core 5 provided with a plurality of slots 17 extending transversely to the path and forming a plurality of polepieces terminating in a plane adjacent the path, the windings of each coil 7 passing through two of the slots spaced in the direction of the path, the coils overlapping one another in the direction of the path, and the current controlling means being arranged to effect consecutive energization of the coils in the intended direction of movement of the object to be transported. The object may be supported directly upon the extremities of the polepieces or it may be supported by non- ferrous rollers. The apparatus may be used for conveying articles through a high pressure container, through acids or through a corrosive atmosphere. By manipulation of the means 6, the field may be reversed in direction so as to brake the movement of the objects 4.

Abstract: 625,650. Ignition systems. BRITISH THOMSONHOUSTON CO., Ltd., WELCH, D. F., and COE, R. T. May 1, 1945, No. 11004. [Class 7 (iv)] An ignition system comprises a source of low tension current such as a magneto or induction coil having associated therewith transformer means for transforming the ignition voltage to an intermediate value at which it is capable of being distributed by a jump spark distributer to the sparking plugs and individual step-up transformers located at or near each plug and connected between the leads from the distributer and each plug for increasing the voltage available for producing the discharge at the plug gap and the constants of the ignition circuit are so chosen that the ratio of the frequencies of the high and low frequency components of the open circuit secondary voltage applied to the plugs lies between 3 and 4.5 and and' between 6 and 8.5 to obtain a peaking wave form of output voltage. The transformer means may be associated with the magneto winding or may be separate therefrom. The object is to reduce the voltage to which the screened distributer leads, &c. are raised and thus reduce the amount of energy taken in charging these leads. To increase the voltage available at the sparking plug the circuit may be arranged as described in - Specification 545,857, referred to, so that the ratio of the frequencies of the higher and lower frequency currents in the secondaries of the sparking plug transformers are between 3 and 4.5 to 1. As shown, a magneto A has associated therewith a secondary winding T1 forming the transformer means and from the secondary Tl the current is supplied to a distributer D. Between the distributer and each sparking plug S a transformer T2 is arranged to step up the ignition voltage to that required for sparking. Condensers C2 and C3 may be arranged respectively between the lead from the distributer and earth and across the transformer secondary. Approximate formulae are given in the Specification for determining the frequencies of the currents in the secondary of the sparking plug transformer.

Patent GB-772523-A (GB)
Abstract: 772,523. Cold-cathode tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 9, 1955 [March 11, 1954], No. 6929/55. Class 39(1). A glow discharge tube has a filling of neon and/or helium, the product of gas pressure and the distance between the main electrodes being such that in normal operation the anode is located in the Faraday dark space, the anode voltage drop being completely developed for the normal operating current, without a column discharge occurring. The product of pressure and distance is preferably so chosen that the ratio between the igniting voltage and the operating voltage is at least 3À5 and may be as high as 6. The voltage pulse occurring upon ignition is consequently at least 2À5 times the operating voltage and is sufficiently large to initiate the ignition of other discharge tubes, for example in automatic telephone exchange circuits. As an example, a glow discharge tube is filled with helium at 13 mm. of mercury pressure and the main electrodes are two circular nickel plates 30 mm. in diameter and covered with barium-strontium oxide. For a distance of 33À5 mm. between the electrodes the striking voltage and the operating voltage are 380 volts and 89À3 volts respectively, which corresponds to a ratio of 4À3.
