Title: Improvements in or relating to theodolites
IPC: G01C1/02
Filed: 1940-08-14
Abstract: 541,948. Theodolites. COOKE, TROUGHTON& SIMMS, Ltd., and TAYLOR, E. W. Aug. 14, 1940, No. 12993. [Class 97 (ii)] In an optical theodolite having vertical and horizontal circles of transparent material bearing graduations thereon, and optical systems adapted to produce images of both graduations in a common focal plane, a transparent index setting plate is provided through which light rays from the vertical circle pass, the index setting plate being angularly adjustable about an horizontal axis for the purpose of displacing the image of the graduations on the vertical circle laterally into accurate registration with a datum line or pointer in order to obtain accurate readings. As shown, light reflected from a mirror 1 forms, adjacent to a field lens 13, images of the graduations on the vertical and horizontal circles 5, 24 by means of the optical systems described in Specification 541,947. These images, together with an horizontally adjustable fine reading scale 12, are viewed through an eye piece 19 and the graduations are read off against pointers carried by an apertured masking plate. The rays form ing the image from the vertical circle 5 pass through a parallel plate of glass 8 capable of rotation about an axis VI ... VI by means of an adjusting screw, in order to displace the vertical circle image within its masking aperture. To correct the datum reading, the vertical circle image is displaced by rotating the adjusting screw so as to bring the appropriate graduation into accurate registration with the datum pointer in the mask aperture. In a modification the datum setting of the vertical image is effected by levelling an altitude bubble 60, Fig. 4, in the line of sight. The bubble is carried by a frame 61 rocked by means of a setting screw 62 which, through a ball connection 64, also imparts a rocking movement to the index setting plate 8 and thereby deflects the vertical circle image the appropriate amount. The eyepiece assembly 55 is detachably secured to the instrument by a threaded ring 56 which permits angular adjustment and ready detachment for stowage in its box.

Title: Improvements relating to apparatus for the digital representation of speech
IPC: G10L19/00
Filed: 1965-03-29
Abstract: 1,078,829. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13170/65. Heading H4R. In a vocoder system each spectrum channel is sampled once per cycle of the fundamental frequency of the speech signal and the resulting signals transmitted in digital form. Fig. 1 shows a preferred embodiment in which speech from a microphone M is divided into a number of frequency bands by band-pass filters BP the signals from which are rectified by rectifiers G and passed through low-pass filters TP 1  to form analogue signals corresponding to the variations in energy of the individual frequency bands of the original speech. The speech is also fed through a low-pass filter TP 2  to a zero crossing detector ND to develop a pulse at the fundamental frequency of the speech. The fundamental frequency pulse is fed through a delay unit VZ, comprising e.g. cascaded monostable switching circuits, to synchronize the signal with the spectrum signals, before the signal is applied to a data processing unit EDV. The data processing unit controls the sampling switch S so that each spectrum channel is sampled one per pitch pulse. The resulting samples are fed via an analogue digital converter to the data processing system EDV for storage and subsequent transmission. The fundamental frequency signal is also digitized in the data processing unit by a counter.

Speed indicators operating by sighting aerial objects.-Relates to apparatus for controlling the tire of guns used against aircraft or other fast moving targets and consists (a) in an instrument in which the setting of an observing-instrument on the target gives directly the bearing angle and angle of sight of the target on a co-tangent chart, i.e. a chart in which radial lines indicate the bearing, and concentric circles, at distances from the centre proportional to the co-tangent of the angle of sight, indicate the angle of sight, and (b) in an instrument having mechanism for predicting the future positions of the target comprising an expanding or variable scale formed of a helical spring, the convolutions of which form the graduation marks. In the construction shown, the observing instrument and the indicator are mounted on a carrier 2, 3, 15 mounted to rotate about a vertical axis above a table 1 on which a co-tangent or other chart is placed. The observing instrument (not shown) is mounted on a platiorm 19, adapted to be elevated by a cam 26 operated by a hand wheel 39, Fig. 2. The indicator is carried by a block 43 mounted to move radially in an arm 2 of the carriage, and operated by an endless band 29 which passes over an end pulley 30 and over a drum 28, fixed to the elevating cam 26. To train the observing instrument, the whole carriage is rotated by means of a hand wheel 13, Fig. 2. The indicator, Figs. 1 and 5, comprises a present position pointer 51 and a future position pointer 60 carried by an arm 52 on a casing 47 carried by a vertical pivot 49 on the block 43 and maintained with the arm 47 pointing in the direction of travel of the target 'by the trailing wheel 50. The wheel 50 is graduated and the velocity of the target is determined by observing the amount of rotation of the wheel during a measured time. The pointer 60 is adjusted along the arm 52 in accordance with this ascertained velocity with reference to an expanding scale comprising a helical spring, the coils of which serve as the indicating marks, the compression of which is adjusted by a piston 54 connected by a cable 55 to a shaft 56 adapted to be rotated by an indicating arm 57 in accordance with the observed rotation of the wheel 50. Other forms of expanding scales may be used such as a plate or travelling band having divergent graduation marks. For indirect firing, the bearing angle and angle of sight are read at the future-position pointer 60 by means of a reading scale 71, Fig. 5, pivoted centrally above the table and having a radial edge 75 on which the angle of sight is read and a pointer 76 at the end which indicates the bearing angle on a scale at the edge of the table. For direct firing a reading scale 80, Fig. 8, is employed. The radial edge 81 is brought against the present position pointer, and the lateral and vertical corrections are read on the scale against the futureposition pointer. A fuse-time indicator of the kind described in Specification 129,372, [Class 92 (ii), Ordnance &c.], may be employed.
