[Class 106 (i)] [Also in Group XX] An instrument for determining latitude and longitude or effecting other navigational calculations comprises a circular azimuth indicator 2, Fig. 14, a semicircular altitude arc 3 having a radial aixs of rotation coinciding with axis of the ring 2, a semicircular rotatable latitude indicator 12 with its axis coinciding with a diameter of the ring 2, a circular rotatable longitude indicator 23 with its axis coinciding with the diameter 14 joining the ends of the latitude arc 12, and a semicircular declinationindicator 15 rotatable about a diameter coinciding with the diameter 14. The longitude indicator 23, an hour indicating ring 22 and a star chart 21 are concentrically and rotatably mounted on a plate carried by a bracket to which the latitude arc 12 is secured and which is hung from the main frame (not shown) supporting the ring 2 by pivots aligned with the E-W axis of the ring 2. The adjustment of the various parts is effected by micrometers. The azimuth ring 2 and altitude arc 3 may be separated from the rest of the instrument and fitted on top of a compass 6, Fig. 12, to enable the altitude and azimuth of a celestial body to be determined. A sleeve 9b slidable . on the arc 3 and adjustable by means of the micrometer screw 9g detachably carries an L-shaped sighting tube 10 of which the longer leg 10a extends towards the centre of the ring 2 where the light is reflected by a prism along the shorter leg 10b to a ground glass 10d. The image of the observed body is brought into coincidence with cross wires on the screen 10d. The sighting tube 10 is removed before replacing the ring 2 and arc 3. Alternatively, the altitude and azimuth may be observed independently by a sextant &c. A sleeve, which may be adjusted on the arc 15 to the known declination of the observed body, carries a spring urged centring member which may be brought into register with a co-operating socket on the slide 9b by adjustment of the latitude arc 12 and declination arc 15. Fig. 14 shows the 24‹ 30' graduation on the arc 3 registering with the 12‹ S. graduation on the arc 15, the latitude, 32‹ 40', being indicated by the point at which the ring 2 cuts the arc 12. The longitude indicator 23 when adjusted so that the graduation corresponding to the time of observation, 10-52 p.m., is at the declination arc 15 indicates the longitude, 117‹ W., by the graduation at the uppermost point. The longitude indicator 23, hour indicating ring 22, and star chart 21 are adjusted relatively to each other in accordance with the various time reckonings. Reference has been directed by the Comptroller to Specification 20909 /91, [Class 97].

Filed: 1919-09-17
Abstract: 152,498. James, R. W., (Remington Typewriter Co.). Sept. 17, 1919. Type lever actions.- Relates to type-actions in which the connexions comprise slotted members engaging pins, and consists in a special form of slot. The invention is shown in Fig. 2 as applied to an action in which a type-lever 14, pivoted at 15, is formed with a slot 18 engaging a pin 12 on a sub-lever 9. The slot 18 is now formed at one end with an enlargement 23 which is of greater depth than the slot and is of less width than the diameter, or preferably, than the radius, of the pin 12. The slot may also be formed with the usual enlargement 21 for the passage of the head of the pin during assembling. The walls of the slot terminate in shoulders 20, 22 and each wall is scraped smooth longitudinally from one shoulder to the other, the enlargements 21, 23 permitting of the edge of the scraping-tool to pass into the enlargement 21 or 23 at the end of each stroke. The walls of the slot are rounded off laterally to prevent the pin from binding, particularly when the sub-lever and the type-lever are arranged to move in different planes. When the action has been assembled, the type-levers are left unsupported at the front, and the pins 12 are permitted to engage the end walls of the enlargements 23. If any of the types then deviate from the general arc, the sub-levers 9 associated with those types are lengthened or shortened, by swaging or bending, to cause the types to lie in the general arc. The type-rest is then placed in position and the type-levers are thereby raised slightly, the pins 12 being caused to leave the walls of the enlargements 23 and engage the walls of the slots 18.

Abstract: 1,099,966. Fluid-pressure servomotor systems. BORG-WARNER CORPORATION. May 31, 1965 [June 4, 1964], No. 23139/65. Heading G3P [Also in Division F4] The setting of a throttle valve in the suction line of a vehicle mounted refrigeration system is controlled by a pilot valve which is responsive to the evaporator pressure and to a manually adjustable control pressure. As shown, the throttle valve A comprises a slidable member 10 formed with spools 12, 13, 14, spool 13 controlling communication between lines 15 and 16 which respectively communicate with the evaporator 4 another suction side of the compressor 1. A chamber 17 at one end of member 10 is in permanent communication with line 15 via a bore 19 in member 10 while a chamber 18 at the other end of member 10 communicates with line 16 via lines 21, 22 under the control of the valve member 23 of pilot valve B. Two diaphragms 25, 26 are connected to member 23, one side of diaphragm 25 being subject to evaporator pressure via line 29, one side of diaphragm 26 being subject to atmospheric pressure and the space between the diaphragms being subject to an adjustable control pressure via line 28. The latter communicates 'with the inlet manifold 7 of the vehicle engine 6 and includes an adjustable constant pressure valve 8. The arrangement is such that if valve 23 is closed the pressure in space 18 becomes equal to evaporator pressure due to leakage past spool 14 and a spring 31 moves member 10 to the closed position. If valve 23 is open then the forces on member 10 are sufficient to overcome spring 31 and cause member 10 to open. Equilibrium occurs when the rate of leakage past spool 14 is equal to the rate of escape through lines 22, 21.

Abstract: 1,042,172. Stereophonic radio receiving systems. RADIO CORPORATION OF AMERICA. June 11, 1963 [July 2, 1962], No. 23268/63. Heading H4L. A receiver for stereophonic radio signals is provided with means for preventing intermodulation distortion due to interaction between the 19 kc/s. pilot signal and L+R or L - R signals which are approximately subharmonic thereto arising in the stereo demodulator if relatively simple filters are used which do not completely remove the pilot signal component. As shown, the complex signal consisting of a 19 kc/s. pilot signal, the L+R signal and the L - R subcarrier sideband is supplied by a conventional F.M. detector 8 and amplifier 23, having a network 22, 30 in the cathode circuit to boost the high-frequency response, to an amplifier 18. The anode circuit 36 of the amplifier 18 is tuned to select the pilot signal which is frequency doubled by a full wave rectifier circuit 39 to control a 38 kc/s. oscillator 47 which is biased to cut off in the absence of the pilot signal by the voltage developed across resistors 55, 56. Thus automatic switch-over from mono to stereo is provided and a neon tube 33 provides an indication of stereophonic reception. The 38 kc/s. switching signal from the oscillator 47 is supplied to a balanced demodulator 57, the L - R subcarrier sidebands being supplied to the demodulator from the junction of resistors 67a, 67b via a bandpass filter and de-emphasis network 66 which also rejects any unrelated signal on a 67 kc/s. subcarrier which may be present. Resistors 67a, 67b, resonant circuit 37, 38 and resistor 31 form a bridge circuit, the values of resistors 67a, 67b being selected so that substantially no pilot signal voltage appears at their junction. The demodulated L-R signals developed across capacitor 63 are supplied to a phase-splitter 74 and combined in opposite phases in resistors 79, 80 with the L + R signal supplied from the potentiometer 31 via a de-emphasis network 85 to 88 which also removes unwanted components. The resulting L and R signals are amplified separately and supplied to the respective reproducers.
