Title: Improvements in or relating to windows of stained glass or like material
IPC: E06B3/00
Filed: 1956-10-22
Abstract: 837,613. Coloured windows. THOMPSON, M. D., and DRURY, C. E. Oct. 21, 1957 [Oct. 22, 1956], No. 32072/56. Class 20(3) A coloured window comprises a group of transparent, or translucent, pane elements 1...4 mounted respectively in tubular frames 6...9 fitted together in an outer box-like frame 5 and a similar group of pane elements, of which two 10, 11 are shown in Fig. 2, located behind the first group. The pane elements may be inclined, or perpendicular, to the axis of the outer frame 5 and, in the latter case, the elements such as 1, 4, Fig. 2, may be co-planar or relatively axially displaced. The inclined elements such as 10, 11 may meet at neighbouring edges or, as shown, may have no contiguous edges. Each pane element may be of uniform colour, comprise a number of colours, or incorporate a coloured picture, the panes behind one another preferably being of different colour compositions. While the pane elements in the two groups shown in Fig. 2 are mounted in common frames extending throughout the depth of the main frame each pane element may have a separate channelled frame so that the shapes and sizes of the pane elements may be more varied. In the embodiment shown in Fig. 5 some of the individual frames for the pane elements terminate in apices within the depth of the window. In clerestory window constructions the ends of the frames may extend beyond the supporting wall the outer transparent pane elements preferably being upwardly inclined to receive light from the sky. The main frame of the window can be made as an integral unit 17, Fig. 13, e.g. by moulding from a synthetic plastic, by casting from a settable material, or by cutting passages between the front and rear faces of a solid block of material the passages being provided with steps, as at 18, to seat the various pane elements which may be held in position e.g. by cement. All of the individual frames for the pane elements are preferably made of transparent, or translucent, material they may, however, be formed of opaque material such as lead, metal, or wood. The transparent, or translucent, frame material may be coloured. The whole, or part of the inner area, of all of the frames may be highly reflective.

Title: Improvements in preparation of p-nitrodiphenylamine
Filed: 1956-10-22
Abstract: p-Nitro-diphenylamine is obtained by reacting aniline and p-nitro-chlorobenzene, a hydrochloric acid acceptor and a copper catalyst compound at temperatures of 170 DEG  to 200 DEG  C., a substantially anhydrous condition being maintained during the reaction by continuously distilling off the water formed as a by-product of the reaction.  The reactants may be heated in a flask fitted with either a fractionating column, still head, condenser and receiver, or a reflux condenser and a Stark and Dean Trap.  Examples are given (i) using 800 mols. per cent excess of aniline with potassium carbonate as the acid acceptor and cuprous iodide as the catalyst in a fractionating column and receiver apparatus; (ii) as (i) but without distilling off the water, this example being given for comparison; (iii) using 50 mols. per cent excess of aniline with other reactants as before and with the addition of benzene as an azeotroping liquid in a Stark and Dean type apparatus.

Title: Improvements in or relating to Superconductive Layer Stores
IPC: H01L39/00
Filed: 1967-07-13
Abstract: 1,191,135. Superconductor devices. SIEMENS A.G. 13 July, 1967 [14 July, 1966], No. 32192/67. Heading H1K. In a superconductor layer store of the kind in which information is stored as circulating currents in a superconductor memory plane at the intersections of bit-lines and word-lines, the bit-lines and word-lines are arranged on opposite sides of the memory plane, the thickness of the plane being of the order of magnitude of the penetration depth of the fields of the writein currents. As shown, Fig. 1, word-lines 2 and bit-lines 3 are arranged on opposite sides of the memory plane 1 and have narrow sections 21, 31 respectively, in register to define the storage cell. Memory plane 1 comprises a layer of tin and the write-in lines 2, 3 comprise layers of lead insulated from plane 1 by layers of silicon monoxide. The device may be produced by vapour deposition on a substrate of glass or ceramic, using the same mask for the narrow parts 21, 31 of the word- and bit-lines 2, 3 to ensure exact registration. The device may be covered with an insulating layer and a protective layer. In an alternative embodiment, Fig. 2 (not shown), the word- and bit-lines merely cross at right angles and do not have narrowed parts. This embodiment may be modified by changing the angle at which the lines cross. In use, half pulses are applied to the word- and bit-lines as appropriate and where two pulsecarrying lines cross the circulating currents induced in the memory plane add to produce a magnetic field of sufficient magnitude to drive two areas of the plane normal so that the flux can pass through the plane and enclose both write-in lines. When the write-in pulses are removed the flux is trapped. To read out the stored information a larger pulse of opposite polarity is applied to the word line which reverses the direction of the trapped flux where a bit has previously been recorded and this induces a pulse in the associated bit-line. Since the trapped flux encloses the word- and bitlines, which are superconductors, it is prevented from withdrawing from the memory plane if for any reason the normally conducting areas tend to go superconductive (Fig. 4, not shown).

Title: Improvements in or relating to watch movements
IPC: G04B17/04
Filed: 1966-07-20
Abstract: 1,138,818. Watches. BERNARD GOLAY, S.A. July 20, 1966 [Aug.13, 1965], No.32671/66. Heading G3T. A watch movement comprises a gear train 2-6 driven by a motor 1 and a regulating device formed by two vibrating systems 8, 9, the vibrations of which are maintained by the motor via the gear train. An intermediate wheel 5 meshes with an escape wheel 6, the teeth of which strike pallets 11, 12 mounted on an arm 10 of the secondary vibrator 9. The motion of the vibrator 9 is transmitted to the primary vibrator 8 by the pallet 12 striking a tine 8a of the vibrator 8. The vibrator 8, which as shown is a tuning fork but could comprise a single blade or an O or H-shaped resonator, thus synchronizes the frequency of oscillation of the two vibrators and thereby regulates the watch. In a modification, the secondary vibrator 9 comprises a blade and a single pallet. Instead of the mechanical coupling between the vibrators, spring or magnetic coupling could be used and the vibrator 9 could also be a tuning fork.

Abstract: 944,664. Pulse modulation circuits. TELEPHONE & ELECTRICAL INDUSTRIES PTY Ltd. Sept. 12, 1961 [Dec. 13, 1960], No. 32703/61. Heading H4L. [Also in Division G1] A pulse width modulator for use in a conveyer belt aggregate weight measuring apparatus (Division G1) has one input which is a voltage of belt deflection dependent magnitude and a second input which comprises pulses the rate of which is dependent on belt speed. The modulator 11 (Fig. 3) comprises an emitter follower stage TR1 the input voltage c (Fig. 2) of which appears at the resistor R1 so that when a transistor TR2 is switched " on " by a pulse from the belt speed indicator (waveform d), a capacitor C is charged to the instantaneous voltage at R1, and at the termination of the pulse, the capacitor C discharges linearly through TR3 and R3 in a time proportional to the instantaneous voltage. Transistors TR5 and TR6 are arranged so that when the emitter of TR5 rises above earth potential, TR5 is switched " on " and TR6 " off " this occurring as soon as capacitor C charges through TR2, and until C is completely discharged. The output of transistor TR6 is thus a series of negative pulses of a duration proportional to the weight dependent input voltage to TR1, and of a frequency equal to that of the belt speed indicator output signal to TR2 (waveform e).

Title: Improvements in or relating to the tail surfaces of aircraft
IPC: B64C5/16
Filed: 1927-12-06
Abstract: 313,415. Macmillan, N. Dec. 6, 1927. Steering and balancing - To prevent stalling in aeroplanes, slots are opered automatically or positively at the leading edge of the tail plane so as to reduce, balance, or over balance the effect of the elevator as the machine is forced to its critical angle. Thin planes d, mounted on parallel linkages, may be normally held against the upper surface of the leading edge of the tail plane by air pressure, but so arranged that as the critical angle is reached the junction between the planes is presented to the relative wind and the thin planes are raised to open slots. The thin planes may alternatively be moved positively by link connections to the elevator, or by the elevator controls, through a lost motion device permitting a predetermined range of movement of the elevator without affecting the thin planes. The thin planes are returned to their normal position, in these modifications, by springs. Fig. 5 shows a modification in which an auxiliary plane d is mounted on a fixed part of the fuselage to fit against a movable tail plane a so that a slot is formed as the forward end of the tail plane is depressed. Alternatively a plane d. Fig. 6, mounted on parallel links d<1> of which one has an extension d<3> is moved to open a slot when a stop o, on the cable for moving the tail plane, engages the extension d<3>. fig. 9 shows a modification in which a lever y for moving the plane d can be left free or locked in any relative position to an elevator control lever q so that the pilot can vary the angle at which the slot will open or leave the slot permanently closed at will.
