Title: Improvements in crossed-pointer instruments
IPC: B64D45/00
Filed: 1944-05-26
Abstract: 632,775. Indicating-apparatus. SPERRY GYROSCOPE CO., Inc. May 26, 1944, No. 10276. Convention date, May 26, 1943. [Class 106 (iv)] [Also in Group XL (c)] In a crossed-pointer instrument for indicating the displacement or deviation of an aircraft or similar body in two directions from an externally prescribed and predetermined path by means of crossed pointers mounted in a casing and moving left and right or up and down respectively over a mask forming a background reference, the mask is angularly movable and is caused to turn relative to the casing as the craft moves about its roll axis so that an indication of the bank of the craft is provided. The crossed pointers 11, 12 move horizontally and vertically over a mask 13 formed as a segment of a sphere and provided with reference lines 16, 17 which may be graduated. The pointers 11, 12 are controlled by coils, one of which is shown at 15, to which are fed signals representative of the deviations from the prescribed path. The motion of the craft about its roll axis is derived from a gyro arrangement, Fig. 6 (not shown), comprising a gimbal ring and a rotor casing having pivotal movement in the ring, and an indication of the movement is transmitted to a Selsyn receiver 30 fixed to the casing 10 and whose rotor is coupled at 37 to a sleeve 22 integral with a mirror 20 which is connected to the mask 13 by a curved plate 21. The mask is illuminated by a lamp 42 mounted in the sleeve 22 which includes a rod 44 of " Lucite " or similar transparent material. The mask preferably comprises upper and lower portions formed of light and dark translucent material to form a dark horizontal line 16 whose movement relative to the index points 41<SP>1</SP>, Fig. 1, is easily observed. The pointers may be of light-polarizing material forming a dark intersection or they may be slotted, Fig. 5 (not shown), and the rear surface of the mask may be frosted.

Title: Improved Means for Measuring the Velocity of a Moving Body.
Inventor: KENT WALTER GEORGE
IPC: G01P3/64
Filed: 1917-07-20
Abstract: 117,653. Kent, W. G., and Hunt, N. H. July 20, 1917. Speed indicators operating by sighting terrestrial objects.-Relates to means for indicating the speed of aircraft or other vessels, either to the person on board, or to an observer on the ground or on shore. The movement of a pivoted sightbar between a fixed and an adjustable stop causes the starting and stopping of a watch, the dial of which is graduated to indicate the speed, the adjustable stop being set according to the altitude or distance. The sight-bar 3, carrying sights 1, 2, is mounted in a tube 4 which is secured to a spindle 6, on the other end of which is fixed a feeler 10. This feeler is connected by a C-spring 11 to an arm 12 adapted to be moved by a handle 13 between fixed jaws 15, 16, the spring connexion causing the feeler, and therefore the sight-bar, to move through the variable distance between the fixed stop 17<a> and the altitude cam 14. The arm 12 carries a cam-ended finger 24 which, on each movement of the arm, turns a pivoted lever 25 adapted to start or stop the watch 26, the hand 27 of which rotates round the speed-graduated dial 28, Fig. 4. The cam 14 is set by a knob 20 carrying a pinion 19 which meshes with a crown wheel 18 fast on the cam and also with a second crown wheel 21 which is fast with an altitude ring 22, Fig. 4, encircling the speed dial and reading against a fixed pointer 23. The sights 1, 2 can be set, for drift correction, at right-angles to the true course, by means of a sighting-tube 36 which is fitted with a graticule 37 at its lower end and rotates in a tube 35, and a pin-and-slot device connecting it with the sight-bar 3. The observer sets the ring 22, and thereby the cam 14, to the altitude, adjusts the sights for drift, and on sighting an object on the ground throws the sight-bar over, thus starting the watch, to the position determined by the cam 14. When the object again passes the line of sight, the handle is thrown back and stops the watch, the hand of which indicates the speed. For bomb-dropping, the ring 22 is turned by means of the knob 20 until the altitude figure on its outer scale 42 is opposite the speed figure on the fixed scale 43, thus effecting a new setting of the cam 14. The lever 12 is now moved to bring the feeler 10 against the cam, thus setting the sight bar in its advance position for releasing the bomb at the instant when the target object comes into the line of eight.

Title: Electrical comparator network
IPC: G06F7/02
Filed: 1958-04-08
Abstract: 843,723. Digital electric calculating apparatus. WESTERN ELECTRIC CO. Inc. April 8, 1958 [March 28, 1957], No. 11042/58. Class 106 (1). An electrical network for comparing two binary numbers is arranged to carry out a digit by digit comparison beginning with the most significant digits, and provides outputs collectively indicating the exact magnitude of the difference between the numbers. The comparator network shown comprises stages A, B ... N to which are supplied the digits a 1'  a 2  ... an and b 1 , b 2  ... b n  of the two binary numbers to be compared. The stages are identical except that the end stages A and N are simplified. Each intermediate stage such as B comprises: a comparison portion, including an " exclusive OR " circuit 240, AND circuits 245, 250, and OR circuits 265, 270, which receives a " carry signal c 1  or d 1  from the next higher stage A and supplies " carry " signal c 2  or d 2  to the next lower stage; and an output portion including AND circuits 285, 290 which are responsive to the carry signals and also to signals from the next lower stage. The output signals from circuits 285, 290 are applied to resistors R 2  connected to positive and negative lines 296, 297 respectively. The resistors such as R 2  have values weighted according to the corresponding binary powers, thus forming a digital-to-analogue converter 295, and the weighted signals obtained on lines 296, 297 are algebraically combined in circuit 298 to form an output signal at 299 indicating by its magnitude the exact value of the difference between the two numbers. The comparator network operates according to rules, given in the Specification, such that, if the compared digits in any stage mismatch, an output is, in general, obtained, but if the digits in one or more succeeding positions mismatch in opposite directions an output is obtained from the stage corresponding to the last of the oppositely mismatched digit pairs but with the polarity of the first mismatch pair. Thus e.g. if the two numbers 5=0101 and 8=1000 are applied to stages A, B, N-1, N, there would be no output in response to the negative mismatch in stage A, but an output representing " - 4 " would be obtained from B: also a further output representing "+1 " would be obtained from stage N. These outputs would be combined in 298 to produce a difference signal representing " - 3 ". The comparator may be employed for address selection in a C.R.T. storage system as described in the Specification. Specifications 836,234, 836,235 and 843,722 are referred to.
