IPC: B60Q1/38
Filed: 1922-07-03
Abstract: 204,149. Wheeler, H. G. July 3, 1922. Road-traffic signals on vehicles.-In signalling apparatus for motor vehicles, means are provided for placing the rear and side lights in an interrupted circuit in order to convert any desired lamp into an intermittent light for the purpose of signalling the driver's intention to stop or turn. The front and rear lights 11, 12, 13, 14 and an electric motor 8 are connected across mains 1, 2. The switches 4, 5 connected in the left and right hand circuits 16, 17 are adapted to connect lights 11, 12 or 13, 14 in series with an auxiliary circuit 20 provided with an interrupter 7 which is driven by the motor 8. Each of the switches 4, 5 is connected mechanically to a switch 4', 5' in the motor circuit so that the motor is switched in simultaneously with the interrupter. A handle located near the driver is connected to the switches 4, 4<1>, 5, 5<1> and is so arranged that when in the central position, the main circuits 16, 17 are switched in, but when the handle is turned in one or other direction to signal the direction in which the vehicle is about to proceed, the main circuit on one side is cut out, and the corresponding interrupter and motor circuits are switched in. To signal " stopping " the rear lights 12, 13 are switched into the interrupter circuit, by mechanically connected switches 6, the motor 8 being simultaneously switched in. The switches 6 may be operated from the brakes and the left and right hand light switches may be controlled by ratchets operated from the steering wheel. The interrupter consists of a commutator 25 having brushes in contact with its periphery.

Title: Method of stabilising saltpetre melts used in the heat-treatment of alloys
IPC: C21D1/607
Filed: 1937-07-01
Abstract: Saltpetre baths for the heat-treatment of alloys, especially aluminium alloys, are stabilized by adding an alkali-metal dichromate in a quantity exceeding 2 per cent but below 25 per cent, the quantity depending on and increasing with the temperature at which the melts are to be used.  The chromate may be replaced by molybdates, tungstates, vanadates or manganates, and, instead of the alkaline metal compounds, the corresponding alkaline earth compounds may be used.  If free alkali is present in the bath, such an amount of dichromate is added simultaneously to the melt that the dichromate is converted into monochromate. The dichromate and monochromate may be added in the form of a mixture.

Title: Electric pulse demodulation system
IPC: H03K9/04
Filed: 1945-07-20
Abstract: 595,894. Pulse modulating systems. STANDARD TELEPHONES & CABLES, Ltd. July 20, 1945, No. 18706. Convention date, Jan. 6, 1944. [Class 40 (v)] In a demodulator for time modulated pulses, a first wave is produced having a frequency equal to the average pulse recurrence frequency, the frequency being divided to produce a second wave of which the first is an even harmonic, a third wave being produced which is an harmonic of the second and is fed to a biassed mixer, together with the modulated pulses, the output. being in the form of amplitude modulated pulses. The system is described as applied to pulses modulated in the manner described in Specification 586,098, pairs of consecutive pulses being displaced in opposite direction from their normal positions. The time modulated pulses 12 are utilized to shock excite a tuned circuit 15 to maintain oscillations 16 of a frequency equal to the average pulse recurrence frequency. A frequency dividing circuit 22 produces a fundamental wave of which the wave 16 is an even harmonic, the multiplier 24 producing an odd harmonic of the fundamental wave which is fed over a phaseshifter 26 to a mixer unit 30, also fed with the pulses from amplifier 40, and normally biassed beyond cut-off. According to the relative position of a pulse with respect to the odd harmonic, the mixer unit 30 passes more or less current during a pulse. The output is fed through a low-pass filter 42 to a reproducer 44. The odd harmonic frequency may be passed through a wave shaping circuit 32 to give a triangular wave which allows the use of wider displacement of the pulses. To reduce the effect of interference, the fundamental wave 16 from the divider 22 is fed to. a wave generator 64 producing a negative-going waveform of duration equal to the time between displacement limits, which is applied to amplifier 40 to render it ineffective during these periods.
