Title: Improvements in apparatus for graphical computation for the solution of navigation problems and similar problems
IPC: G06G1/14
Filed: 1942-06-02
Abstract: 560,952. Calculating- apparatus. BYERLY, R. W. June 2, 1942, No. 7483. Convention date, June 27, 1941. [Class 106 (i)] Apparatus for graphically solving navigational problems for obtaining the great circle distance between two points on a spherical surface comprises a chart bearing a gnomonic projection and an element pivoted on the chart at the point of contact of the said projection on which can be plotted the data to set off a line of position. In the form shown in Fig. 1, the chart A bears great circle projections of the parallels and meridians of a sphere with the contact point at the equator and the plotting element is formed as a transparent sheet 10 with a roughened surface to facilitate marking. After numbering the meridians with the desired graduations the position C1 of an observed celestial body and the dead-reckoning position S1 are marked on the transparent sheet. The sheet is then swung round the pivot until the line C1-S lies on, or is parallel to, a common meridian as shown at C<1>1-S<1>1. The latitude of these points are read off and the algebraic difference gives the great circle distance which is the zenith distance of the celestial body. By comparing the calculated distance with the observed zenith distance, the off-set of the line of position from the dead-reckoning position is obtained. In a modification, the chart is divided into two halves ; the plotting half bears a projection with the contact point at a pole, while the measuring half has a projection with the contact point at the centre. In another form, the chart has the point of contact on an intermediate parallel of latitude. Instead of a transparent sheet, other types of elements for plotting the data may be used. These elements may comprise slidable and pivoted rules.

Title: Improvements in Cancelling Mechanism for Signalling Devices for Collieries and other Mines.
Inventor: GAINEY HERBERT HARRY
IPC: B66B19/06
Filed: 1916-05-27
Abstract: 101,605. Gainey, H. H. May 27, 1916. Mechanical telepraphs; mine signals. - In ratchet-wheel step-by-step signalling-apparatus such as is used in mine signalling, the first impulse of a signal cancels the previous signal by means of a link pivotally connected to the usual cross-shaped lever to which the signalling-wire is connected. The link first raises the detent to allow the signal pointer to return to zero, and is then disengaged from the detent by mechanism operated by, and having lost-motion connexion with, the cross-shaped lever. Return of the link into engagement with the detent is suitably retarded, to allow completion of a signal by subsequent impulses. The signal wire 1 is connected to one of the arms 2 of the usual pivoted crossshaped lever, which serves to operate the hammer 4 of an audible signal bell 3, and also operates the ratchet-wheel 5 and pointer 6 step by step by means of a pawl 31 pivoted to one arm of the lever. A link 8 pivoted to the lever has a hooked end engaging a lug 10 on the detent pawl 7, so that the first part of the signalling-impulse raises the detent, allowing the pointer 6 to return to zero. Further movement of the lever then raises the link 8 clear of the lug 10, allowing the detent 7 to re-engage with the ratchet-wheel, by means of links 16, 18, the latter having lost-motion connexion with the lever by a pin and slot 28, 27. The ratchet-wheel is then moved one step bv the pawl 31. Fall of the link 8 to re-engage the lug 10 is retarded by a dash-pot 21, thus allowing the signal to be completed by subsequent impulses.

Filed: 1928-03-12
Abstract: 291,369. Gandriaut, L. May 31, 1927, [Convention date]. Computing-apparatus.-In weighing- apparatus wherein a carrier bears a number of graduated scales adapted to be brought individually into view behind a window, means are provided whereby the desired scale is brought into position by pressing a tappet. In Figs. 1 and 4, two forms of the device are shown, with mechanical and electrical drives respectively. A stationary plate 16 carries a ring of tappets 18 one tappet for each of the graduated scales carried upon a drum 1, the graduated scales on the drum being capable of display singly through a window. When a tappet is pressed in by the operator a spring-pressed plate 10 is slid along its shaft 5 and thus freed from the restraint of the previously-operated tappet the end 19 of which was engaged within a recess 15 in the plate 10. The plate, shaft 5, gearing 4, 3, and drum 1 are now free to be rotated by a clockwork motor 8. Fig. 1, and the rotation continues until the notch 15 reaches the depressed tappet when the plate 10 is moved to the left by its spring and the notch engages over the end of the tappet and locks the plate with the drum 1 correctly set. The tappet when depressed is retained by a spring 22, Fig. 4, which is however liberated by an arm 23 immediately the disc 10 commences to rotate. In the electrical form, Fig. 4, when the plate 10 is pushed to the right by a tappet the plate is brought into gear with a toothed pulley 13 driven by an electric motor and the circuit of the motor is closed automatically by the closure of a press switch 26.
