Title: Angular velocity sensing and indicating systems
IPC: G01C19/5635
Filed: 1964-10-29
Abstract: 1,063,469. Measuring angular velocity electrically. THIOKOL CHEMICAL CORPORATION. Oct. 29, 1964 [Oct. 29, 1963], No.44228/64. Heading G1N. In a vibrating wire type of angular velocity sensing apparatus, the wire 10, Fig. 1, is cyclically tensioned by means of a spring plate 16 actuated by an A. C. - driven electromagnet 22, so that the wire vibrates transversely of its length in a direction parallel to the lines of force between two permanent magnetic pole pieces 31, 32. Any angular swing, about an axis parallel to the wire, of a frame 14 carrying the wire and pole pieces, results in the wire 10 vibrating in a plane which cuts the lines of flux at an angle, Fig. 3 (not shown), an e. m. f. thus being induced in the wire. The resultant current flow in the wire generates a force which acts on the wire to realign its plane of vibration with the lines of flux (i.e. zero induced e. m. f.). The magnitude of the induced e. m. f. is proportional to the angular velocity of the frame, and its phase sense indicates the direction of angular displacement. The amplitude and phase sense of the e. m. f. are determined by a phase-sensitive discriminator 42 operating in synchronism with the electromagnet supply voltage 26, and are indicated on a meter 50. Since the earth's rotation imparts an angular velocity to the device, it can be used to measure geographical bearing, the small signals obtained being amplified, 60, and indicated, 66. With the wire extending E-W, the output is zero; with the wire extending N-S, the output is maximum, and intermediate directions give intermediate voltages. The transducer may be housed in an evacuated container 54, Fig. 2 (not shown).

Title: Improvements in or relating to space telecommunications systems
IPC: H04B7/208
Filed: 1965-10-26
Abstract: 1,117,746. Space telecommunication system; modulators. NIPPON ELECTRIC CO. Ltd. 26 Oct., 1965 [27 Oct., 1964], No. 45247/65. Headings H3R and H4L. The Specification describes a ground radio station A, Fig. 1 in a space telecommunication system comprising a plurality of such ground stations A, B, C, D each assigned a respective characteristic plurality (e.g. a pair) of radio frequency channels, a 1 , a 2 ; b 1 , b 2 ; c 1 , c 2 ; d 1 , d 2 , Fig. 2, and a communication satellite repeater S, wherein said radio station uses a quiescent carrier system whereby a modulated carrier is only transmitted when a modulating signal is present. In apparatus for one channel, Fig. 3, the modulating signal, e.g. a telephone conversation, is applied at input 11 to frequency modulate the carrier in modulator 13. The presence of a modulating signal is detected by means 16, comprising a rectifier 161 and low pass filter 162 to produce the envelope of any signal at 11, which envelope is applied to a Schmitt trigger 163 whereby an output is produced only when said envelope rises above a threshold indicating the presence of a modulating signal. Such output closes an otherwise open switch 14, whereby the modulated carrier is applied for transmission to a transmitter 15. On the reception side, a filter 43 selects the incoming signal with the assigned frequency and passes it to a demodulator 44. The noise and voice components of the demodulated signal are respectively separated out by filters 462 and 461 and their amplitudes compared at 467, such that only when the voice component is sufficiently greater than the noise component does comparator 467 cause a switch 45, between the output of demodulator 44 and utilization circuits, to close. The invention may be applied to amplitude modulated systems.

Title: Photographic printer
Inventor: BENSON HAROLD ROSCOE
IPC: G03B27/20
Filed: 1961-12-19
Abstract: 943,519. Photographic printing apparatus. NUARC CO. Dec. 19,1961, No. 45559/61. Heading G2A. A photographic printer comprises a cabinet having in its lower part a light source, and in its upper part a printing frame so mounted that it can pivot about an axis to present either face of the frame towards the light source. In the form shown, the printer comprises a cabinet 21, in the lower part of which is a carbon arc light source 22 together with its control mechanism 40. Below the light source is a square reflector 24 of parabolic section. All this part of the apparatus is mounted in a drawer 23, which can be withdrawn from the cabinet for cleaning and maintenance. The printing frame 25 is mounted at the top of the cabinet, and can pivot on pintles 83, 84 so as to turn through 180 degrees. Initially it is turned to a "loading" position in which it can be opened from above so as to place therein negative and a sensitive plate or sheet. It is then closed, pivoted round through 180 degrees, so that the plate and negative are now facing the light source. The exposure is made, the frame inverted once more, opened, and the negative and the plate removed. The frame is formed as a somewhat cup-shaped metal member 78, having a flat bottom 79 and four side walls 80. A glass frame assembly 85, including a plate glass pane 86, is pivotally attached to the rear side of frame 25 by hinges 87. Fig. 11 shows the "loading" position, the glass frame 85 being pivoted up into the position shown in phantom. A spring lift assembly comprising an arm 90 terminating in a roller 91, and a tension spring 93, help to retain the frame 85 both in the closed and open positions. By lifting frame 85 there is exposed a flexible rubber blanket 101 which rests on the bottom 79 of member 78. This blanket is a moulding having a plurality of square truncated pyramid-like protuberences 102, on which are laid the sensitive plate 105 and the negative 106. The frame 85 is now lowered into the position shown in full lines (Fig. 11), and can be latched in that position, the glass pane 86 then resting on the negative 106. By means of a pump 34 housed within cabinet 21, a vacuum is then created between blanket 101 and pane 86, the pump connection being made through one of the pintles which is hollow. The blanket is thus forced by atmospheric pressure against pane 86, so pressing the sheets 105,106 firmly together and against the pane. The blanket has a peripheral arcuate portion 103 (see also Fig. 13, not shown), which, when under compression, provides a hermetic seal round the periphery of the blanket. The whole frame can now be rotated through 180 degrees, and the exposure made. U. S. A. Specification 2, 774, 907 is referred to.

Abstract: 1,025,379. Pens for recording instruments; selective printing. PAILLARD S.A. Nov. 16, 1964 [Dec. 17, 1963], No. 46488/64. Headings B6F and B6P. Between the nozzle 6 of a writing instrument of the type wherein a jet of ink is produced by an electrostatic field and a reservoir 1, a pump 4, Fig. 1, is provided which includes a piston 14 of magnetizable material adapted to move inside a glass cylinder 7 under the action of magnetic attraction exerted by a field winding 15. The clearance between the piston and cylinder wall is sufficiently large to allow ink to flow past the piston without forcing ink from the nozzle 6. A stop member 11 prevents the piston from rising above a predetermined position so that the piston always remains in a position relative to the field winding where the force is substantially constant for a constant current. This force is desirably equal to twice the weight of the piston, so that the piston rises at a specific terminal velocity in the cylinder due to the magnetic attraction, and falls at the same velocity due to gravity. In an alternative embodiment, Fig. 2 (not shown), a permanent magnetic field attracts the piston into its uppermost position, equivalent to the lowermost position in Fig. 1, and a field winding is used to attract the piston to its lowermost position.
