Filed: 1963-03-19
Abstract: 985,353. Making patterns with light beams. GOODYEAR AIRCRAFT CORPORATION. March 19, 1963 [May 4, 1962], Heading G2A. A continuous pattern is produced on a lightsensitive film by projecting a plurality of narrow light beams on to the film and effecting relative movement between the film and the beams in an endless path, at the same time effecting nutating motion in a direction at an angle to the said relative movement, and developing the film to produce a positive image. As shown,a light-sensitive film sheet 44 is secured to the upper surface of a plate 42. This is positioned on a support plate 16 which can be rotated turntable-fashion by a motor 22. Above the film sheet is positioned a light-proof box 25 containing a light source 30. In the base of the box, close to sheet 44, is a series of apertures such as the round holes 34, which thus define a series of narrow light beams falling on sheet 44. As the sheet is rotated, these beams trace a series of concentric rings on the sheet. In addition to this circular movement, the template having the holes 34 is also given a nutating motion at an angle to the said movement, so that more complex patterns (e.g. sinusoidal or square wave) may be obtained. The film is then developed to form a positive. From this,a master negative is prepared which is then used to make a contact print on the surface of a slip-ring commutator coated with a photo-resist layer. After development and subjection to an etching process, the rings remain on the commutator as a conductive circuit pattern. Alternatively the pattern may be formed directly on the commutator. In a modified arrangement (Fig. 4, not shown) the pattern can be formed on a cylindrical or conical surface.

Abstract: 1,011,409. Acoustic ranging. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 19, 1964 [March 19, 1963], No. 10782/63. Heading H4D. The invention relates to an adaptation of the acoustic ranging apparatus for aiding blind persons, described in Specification 978,741, wherein the frequency modulation of the radiated signal has the form shown by the solid line in Fig. 1. The fly-back portion 2 of the modulation, which was substantially vertical in the above Specification, is now rarely steeper than the main modulation portions 1, with the fly-back period T<SP>1</SP> some five to fifteen times shorter than the period T of the main modulation portion. With an object at the maximum usable range R M , the echo signal has a frequency modulation shown by the chain dotted line in Fig. 1, and the beat frequency signal produced from mixing the echo signal with the contemporaneously radiated signal, is as shown by the chain-dotted line in Fig. 3, having a frequency fm during portion 1 and rising to a high value and then falling therefrom during the fly-back period. A rejector circuit is provided which rejects all beat frequencies above fm, such that the beat signal fed to the audio reproducer means has an amplitude varying as shown by the chain-dotted line in Fig. 4, with the signal dropping to zero during the fly-back portion. The operator then beams a high-frequency tone having the power density/frequency spectrum shown in Fig. 6. With a near object the beat frequency signal, shown by the plain dotted line in Fig. 3 has, in addition to the portion at a frequency f produced in the apparatus of the above Specification, and possibly below audible range, a portion rising to a higher frequency, and reaching a maximum frequency of fm for T<SP>1</SP> objects at a range Rm.- The beat signal has a T practically constant amplitude, as shown by the plain dotted line in Fig. 4, and a power density/ frequency spectrum as shown in Fig. 5, the portion at frequency f having a narrow bandwidth and the higher frequency portion having a much wider bandwidth. The latter portion will be audible as a click when the low-frequency portion is below the audible range or too faint. The relationship between T and T<SP>1</SP> is chosen so that an audible click will begin to be heard at the range at which the low-frequency portion becomes difficult to bear.

Abstract: 1331328 Electronic Flash Control MULTIBLITZ DR ING D A MANNESMANN GmbH & CO KG 22 April 1971 [5 May 1970 5 Aug 1970] 10830/71 Heading G2A [ Also in division H3] A flashlight unit comprises a flash tube 16 provided with an ignition electrode 24, a photo sensitive resistor 58 adapted to receive the light reflected from an object, a thyristor 22 connected in series with the tube, a capacitor 60 for integrating the reflected light flux and a quenching circuit for quenching the flash discharge when the integrated light flux reaches a pre-determined level. Closure of a switch 30 enables a capacitor 28 to discharge through the primary of a transformer 26 which supplies an ignition pulse to the electrode 24. Simultaneously, the increased voltage across a resistor 32 due to the closure of the switch, causes a diac 42 to condut and a capacitor 40 supplies a pulse to the gate electrode of the thyristor 22. A storage capacitor 14 therefore discharges through the tube 16 and a voltage appears across a resistor 20. The capacitor 60 charges up to a voltage dependent on the total light flux received by the photo sensitive resistor 58. At the pre-determined level a thyristor tetrode 64 becomes conductive enabling a capacitor 66 to discharge and supply a pulse to the gate electrode of a thyristor 50. A commutating capacitor 46 therefore supplies a positive potential to the cathode of the thyristor 22 which is thereby switched off to quench the tube discharge. In a modification the thyristors 22, 50 are each replaced by a pair of parallel connected thyristors, the diac 42 and the thyristors tetrode 64 also being replaced by thyristors.

An armature 21 co-operates with an electromagnet 13. The piston abuts stop 6a when the electromagnet is de-energized, thereby allowing communication between connections 3b and 3c via passage 6g, the interior of the piston, the clearance between piston 10 and stop 11b, the annular gaps 10a and 7b, and the passage 7a. When the electromagnet is energized, the piston is raised, so that it abuts stop 11b, thereby allowing communication between connections 3a and 3b via chamber 6f, passage 6d, annular gap 10a, the clearance between piston 10 and stop 6a, chamber 6e and passage 6g. Communication occurs briefly between all three connections at the beginning and end of each energization. As shown, the valve is formed integrally with a pressure accumulator 47, and in an alternative, Fig. 3 (not shown), it is formed integrally with a distributor in the form of a plurality of electromagnets which are operated sequentially to open respective ones of a plurality of connections 3b.

Abstract: 117,509. Burnett, H. R. July 28, 1917. No Patent granted (Scaling fee not paid). Delivery of liquids.-In an apparatus for supply. ing hot water or liquid refreshments, the circuit of the electric heaters and of a solenoid controlling the inlet valve of the measuring-vessel is closed after the insertion of a coin by a coin mechanism and switch of the type described in Specification 26966/06, and the switch is opened by a second solenoid, the circuit of which is closed by a thermostat when the liquid in the measuring-vessel attains a predetermined temperature. The liquid in the supply tank A is automatically maintained at a constant temperature by means of electric heaters P. The inlet valve I and outlet valve H of the measuring-vessel B are carried by a spring- controlled lever G, which is connected to the core of a solenoid E, and normally the inlet valve is closed and the outlet valve open. When the switch is clcsed, the circuit of the electric heaters M for the measuring-vessel and of the solenoid E is completed, so that the position of the valves is reversed and liquid flows into the measuring-vessel from the supply tank. The liquid in the measuring-vessel having attained a predetermined temperature, a thermostat R closes the circuit of a second solenoid (not shown), the armature of which withdraws the trip-lever of the switch mechanism (described in the above-mentioned Specification), permitting the switch to open. The lever G thereupon reverses the position of the valves under the action of the spring F and the liquid is delivered through a pipe K. It is stated in the Provisional Specification that gas may be employed as the heating agent.

Abstract: 570,111. Light-sensitive glass. HADDAN, R. (Corning Glass Works). July 5, 1943, No. 10875. [Class 98 (ii)] [Also in Groups VIII, IX and XXIII] After glass, produced from a batch containing a copper compound, a reducing agent, e.g. sodium cyanide or abietic acid, and optionally stannic oxide, has been made and whilst it is still colourless it is subjected to ultra-violet or other short-wave radiations. It may then be heat-treated to turn it ruby red, the change of colour occurring more quickly and at a lower temperature than when non-irradiated copper glass is heat-treated. During irradiation, the glass turns blue, so that, by shielding some parts, a design with some parts blue and the remainder colourless may be obtained if the heat treatment is not given, or with some parts red and the remainder colourless if a heat treatment is given at a temperature and of a duration sufficient to affect only the irradiated parts or if the parts which are to be red are made thicker than those which are to be colourless. The colourless portions may then be irradiated, whereby a design in red and blue may be produced. A glass sheet produced from such batch may, before irradiation, be coated with a photographic emulsion and a negative image formed thereon ; the glass is then irradiated, the negative removed and the glass heat-treated to develop a ruby-coloured image. Alternatively, an object may be illuminated with short-wave radiation, and an image thereof focussed on the glass which is subsequently heat-treated to develop the colour of the image. The invention may also be applied to fabrics made of glass threads of this composition.

Title: Control of supply of feed-liquid to distillation apparatus
Inventor: PEARCE MALCOLM
IPC: B01D3/42
Filed: 1955-04-16
Abstract: Liquid is supplied to a still 10, at a rate proportional to the volume of vapour-delivery, by means of a vessel 1 which is divided into two communicating compartments 3 and 4 by cylindrical wall 5 and weir 6; the liquid flows from compartment 3 through an orifice 7, which is at the same level as the top of the weir, and then passes down through pipe 16 into the still.  An orifice-plate 12 is mounted across the vapour-line 11 of the still; and a pipe 13 connects the vapour-line just below plate 12, to compartment 4. The low pressure end of line 11 and compartment 3 are both at atmospheric pressure.  A pressure-difference between compartments 3 and 4, corresponding to the pressure-differential across orifice-plate <PICT:0798626/III/1> 12, is established and maintains a head of liquid in compartment 3. Liquid is supplied continuously to compartment 3 via line 14; and excess liquid (i.e. that which does flow to the still via orifice 7) overflows the weir 6 and is withdrawn by line 15 through a trap.  The size of orifice 7 may be varied by needle 8 carried by spindle 9. Condensation in line 13 is prevented by introducing a gas, e.g. air, into it through line 17.  When the low-pressure end of line 11 is not at atmospheric pressure, compartment 3 must be closed and connected to the low pressure end of line 11 by pressure-equalizing means.
