Title: Improvements in or relating to aircraft
IPC: B64D25/08
Filed: 1946-01-01
Abstract: 609,229. Safety devices for aircraft. ROBERT, R. A. Jan. 1, 1946, No. 108. Convention date, Sept. 5, 1942. [Class 4] In order to enable the occupants of an aircraft to escape in an emergency, the floor of the cockpit is hinged to the fuselage so as to be releasable therefrom to enable a seat and the occupants to be jettisoned. In the form shown in Fig. 1, the floor 2 is hinged to the fuselage framework 9 upon a transverse shaft 3, and is normally retained in position by a locking mechanism 4. Upon release of the latter the floor 2 tilts until clevis-shaped members 12 thereon (Fig. 3) are able to disengage flats 11 on the shaft 3, and thus detach the floor 2 and pilot's seat 1 from the remainder of the aircraft. Fig. 6 shows the method of uncoupling the controls when the cockpit floor tilts downwardly, by the release of a spring-loaded plunger 32 from a socket 30. Fig. 8 shows a modification in which the pilot's seat 34 is ejected from the cockpit floor 38 by a rubber cord 44 which is released by a mechanism 50 when the floor reaches a predetermined angle of tilt.

Title: Electronic timepieces employing piezo-electric crystal time- standard oscillators
IPC: G04G3/02
Filed: 1974-01-02
Abstract: 1427121 Electronic timepieces SUWA SEIKOSHA KK 2 Jan 1974 [11 Jan 1973] 00138/74 Heading G3T [Also in Divisions G4 and H3] In an electronic timepiece having a crystal controlled oscillator circuit (6) Fig. 2 followed by a frequency divider and driver circuit (4) for driving a display 5 e.g. via a stepping motor, the oscillator circuit is provided with a temperature sensitive capacitor 1, e.g. of barium titanate, for temperature compensation and regulation of the clock rate is effected by periodically blocking a selected number of pulses transmitted by the oscillator to the divider. As shown Fig. 3, the oscillator circuit output signal CL is fed via a blocking gate 7 and frequency dividers 8, 9 to a display drive arrangement (not shown). The output signal CL is also fed to a 4-bit binary counter 10 which is reset by the 10 seconds period output of frequency divider 9 and counts the number of pulses received every ten seconds. When a binary number set by switches 3 at inputs ABCD coincides with the count in the counter 10 a coincidence circuit 11 produces an output pulse (E) Fig. 4 (not shown). In a coincidence signal blocking circuit 12 a pulse F is initiated by each 10 seconds pulse from divider 9 and is terminated by the leading edge of the next occurring coincidence pulse E. The duration of the pulse F is thus determined by the setting of the switches 3 and determines the number of clock pulses periods which are blocked by gate 7. For instance if the switch setting is 0001 one period of the clocking signal CL is blocked at each 10 seconds pulse of divider, as in Fig. 4. If the setting is 0010 two periods are blocked as in Fig. 5 (not shown). If the clock signals are at 32, 768 KHz, one period is about 30À5 Á seconds so that with a setting of 0001 there would be effected a total delay of 0À3 seconds per day. Alternatively the temperature sensitive element in the oscillator may be a resistor or a bi-metal switch means arranged to switch in a selected fixed capacitor to the oscillator circuit.

Title: Method and apparatus for the manufacture of 2:2-dipyridyl
IPC: B01J19/00
Filed: 1961-01-05
Abstract: <PICT:0897473/III/1> <PICT:0897473/III/2> Apparatus for the production of 2,21-dipyridyl comprises in Figs. 1 and 2 a boiler 3 opening into an insulated casing 5 which in turn opens into a condenser 6 open to the atmosphere.  In Fig. 1 a liquid-permeable sintered glass disc 8 extends across a tubular reaction vessel 7 which rest coaxially within 5; a side tube 9 opens into the space between 8 and the end of 7 to extend upwardly along part of the length of 7; Raney nickel catalyst 10 covered by pyridine 11 is placed in 7 to rest on 8.  In operation a further quantity of pyridine 12 is boiled in 3, the vapour passes up through 5 to the condenser 6 in which it condenses and falls back through 7; some of the pyridine is forced through the catalyst 10 and the reaction products together with unreacted pyridine are forced upwardly through 9 and fall back into 3.  In Fig. 2 a tube 13 closed at the lower end rests within 5 and is partially filled with catalyst 14 and then filled up with pyridine 15; a funnel 16 is inserted axially into 14; the pyridine 12 is boiled in 3 and the vapour passes up to 6 where it condenses and falls back into 16; some of the pyridine is forced through the catalyst where it reacts and the 2,21-dipyridyl and unreacted pyridine are carried into 3.ALSO:2,21-Dypyridyl is produced by maintaining Raney nickel in contact with pyridine at elevated temperatures, the products including 2,21-dipyridyl being removed from contact with the catalyst continuously or intermittently by displacement with pyridine.  The unreacted pyridine may be separated from the product, e.g. by distillation, and recycled to the reactor. Preferably the pyridine in contact with the catalyst is maintained at temperatures above 80 DEG C.  The process may be carried out, for example, by percolating pyridine near its boiling point through a porous bed of dry Raney nickel catalyst so that the 2,21-dipyridyl is continuously removed by displacement by pyridine or the liquid pyridine near its boiling point is passed upwardly through a bed of catalyst so that the 2,21-dipyridyl and the unreacted pyridine overflow from the top of the receptacle containing the catalyst. Details of the apparatus for carrying out the process are given.

Abstract: PURPOSE:To widen the discrimination range of a frequency discriminator and to make an automatic offset locking adjustment by feeding discrimination outputs of the 1st and the 2nd frequency discriminators back to an oscillation frequency control part, and controlling the intermediate frequency of an intermediate frequency electric signal to a specific value. CONSTITUTION:The intermediate frequency of an electric signal 10 is discriminated by the 1st frequency discriminator 11 (electric circuit), but when the intermediate frequency deviates from a set value, the 1st control signal 12 proportional to the amount of the deviation is outputted from the 1st frequency discriminating circuit 11 and sent to the impressed current control circuit 32 of a local oscillation light source 6. The 2nd multiplexed light 9, on the other hand, is made incident to the 2nd wide-band frequency discriminator 13. When the wavelength (frequency) of the signal light component 17 is equal to that of a local oscillation light component 18, both incidence positions 19 and 20 are coincident with each other, but when their wavelengths are different, both incidence positions 19 and 20 shift from each other. An electric output proportional to the amount of the deviation is outputted from a detecting circuit 16 as the 2nd control signal 21 and sent to the temperature control circuit 22 of the local oscillation light source 16.
