Title: Improvements in or relating to Sighting Apparatus for Anti-aircraft Guns.
Inventor: DAWSON ARTHUR TREVOR
IPC: F41G1/393
Filed: 1916-03-24
Abstract: 124,778. Dawson, Sir A. T., and Buckham, Sir G. T. March 24, 1916. Sights and methods of sighting.-Relates to anti-aircraft sighting- apparatus of the kind in which the deflexion setting of the sight for speed of target is automatically corrected in accordance with the angle of sight, and comprises an arrangement wherein the means for effecting the correction is initially adjusted in accordance with the ascertained height of the target. A vertical lead correction is effected by the means shown in Figs. 1 and 2. The sight-arm B<1> is controlled by a cam E, set according to the height of the target as described in Specification 16856/15. Upon the sight-arm is a longitudinally slidable bar D<2>, through the medium of which the vertical lead correction is imparted to the sightbar B cartying open or other sights, as shown. For this purpose, the slidable bar D<2> is provided at its fore-end with a transverse bracket or plate d<2> carrying a screw spindle d<4>, upon which is mounted a nut D<3> formed in one with a pin d<5> carrying a block D<5> disposed in a longitudinal slot B<2> in the sight-bar B. Upon the pin d<5> is arranged a pointer d<7>, and upon the bracket d<2> is a " speed of target " scale d<6>. The nut is adjusted on the screw d<4> in accordance with the vertical component of the target speed, by means of a hand-wheel D<4> and bevel-gearing, as shown, carried in brackets on the member D<2>. By this means, a normal lead for speed of target is imparted to the sight-bar. The lead is modified in accordance with the angle of sight by movement of the member D<2> in the sight-arm B<1>, this being effected by means of a lever D<1> pivoted on the cradle and co-operating with a " height " cam C on the gun carriage. The angular position of the cam C is adjusted in accordance with the height of the target by a worm C' carried by a shaft C<2> operated in conjunction with the cam E. A modification is described in which a similar constructional arrangement for imparting lateral deflexion leads to the sight is combined with the device shown in Figs. 1 and 2, in which case, the bar B serves as an intermediate member carrying on its upper surface a second sliding member corresponding to the member D<2> and also a pivoted sight-bar operated by such sliding member, in the same manner as before but in a lateral direction. In a further modification, Fig. 4, the transverse bracket d<2> is replaced by a pivoted plate or bracket B<3> tilted more or less bv means of a link B<6> operated by a " height " cam C. In this arrangement, the block b<3> carried by the plate is adjusted by means of a worm and rack D<0> operated by a hand-wheel D<4>. The cam, instead of being pivoted, is slidable in a guide-plate A<x> under the influence of a cam F on the shaft C<2>.

Filed: 1949-02-23
Abstract: 682,670. Photographic roll-film cameras. CUNNINGHAM, V. Feb. 23, 1950 [Feb. 23, 1949], No. 4938/49. Class 98 (i). In film-feeding mechanism for a roll-film camera a film-feed control roller engaging the film, the circumference of which equals the frame displacement, carries a circular cam-disc having a single notch in its periphery engageable by a spring-pressed dog, and also has a pin upstanding from its surface so as to prick the film once on each rotation and thereby define an inter-frame line. The camera may have a number-counter stepped sequentially and photographed on the film at each film change. As shown, Fig. 4, a roll film holder for attachment to a camera comprises a casing 11 with a rectangular film window 12, which has its edges lined on the inside with velvet or plush and is covered by a plate 12 hinged within the casing. The front of the casing may be removed and plate 13 swung outward to place the supply spool 14 in the casing. The film 19 is led from spool 14 over a guide roller 15 at the hinged end of plate 13, over plate 13 and across window 12 to a guide roller 16, between roller 16 and a film-feed control roller 17 and thence over idler rollers to the take-up spool 18. Rollers 16, 17 are rubber-covered and grip film 19 between them, and carry meshing gears 20. Roller 17 also carries a disc 21, Fig. 6, having a notch into which is urged a dog 22 mounted on a rod 27 with a knob 23 which is pressed against action of a spring to free dog 22 from disc 21. This allows the film-winding to be started, after which dog 22 rides on disc 21 until roller 17 has made one revolution. Since the circumference of roller 17 equals the frame displacement, the film is advanced to expose the next frame without overlap or waste. Roller 17 also carries a pin which pricks the film to mark the divisions between frames. Movement of rod 27 also actuates a counter 26, Fig. 7, mounted on the casing wall, and opens a shutter 28 in an optical system comprising two reflectors and a lens 30 enclosed in a cylinder 31, whereby the numbers on the counter are sequentially photographed on the film.

Abstract: 255,506. Asquith (1920), Ltd., W., Asquith, J. W. S., and Feather, G. Feb. 24, 1925. Drilling-machines.-In drilling-machines having means for simultaneously locking the parts connected with the spindle adjustments automatically when the feed is put into operation, the locking is performed by power on the operation of a press-button or other control member. As applied to a radial-arm drilling-machine a lever A, which is actuated by the press-button or a hand-lever &c., actuates a clutch B splined on a continuously rotating shaft b to engage it with a clutch C loose on the shaft and connected to a worm D gearing with a worm-wheel E. A disc G attached to the worm-wheel carries a crank-pin g<3> connected by a link g<4> to a locking shaft F which locks the spindle-carriage to the radial-arm by means of a pinion J, rack j, another rack and pinion j<2>, and a screw clamping device j<4>, and may also operate other locking devices. The power feed is derived from a continuously rotating shaft h<4> which drives, through worm gearing H and a clutch h<6>, a shaft h' having a pinion h<2> engaging the spindle-rack h<3>. With the parts as shown in the Figure, the power feed is engaged, and on actuating the lever A the shaft F is oscilleted to unlock the spindle adjustments, and simultaneously, by means of a cam h<12> and lever h<10>, to disengage the feed-clutch h<6>. After making half a revolution the disc G allows an arm g<2> on the lever A to drop into a recess g, thusbringing the locking shaft F to rest. On thenext actuation of the lever A the shaft F is oscillated in the reverse direction to lock the adjustments, and simultaneously the cam h<12> allows a spring h<7> to engage the feed-clutch h<6>. The shaft F is brought to rest again by a second recess g on the disc G.

Patent GB-159461-A (GB)
Title: Improved manufacture of condensation products from phenols and aldehydes
IPC: C08G8/28
Filed: 1921-02-15
Abstract: Resinous products are obtained by first condensing phenols with aldehydes in the presence of a basic condensing-agent and then adding to the oily or resinous condensation product an acid or substance of acid reaction. If the acid is a mineral acid of high electrolytic dissociation constant, and is used only in amount sufficient or less than sufficient to neutralize the base present, the product obtained is a "resole," i.e. a resin which can be converted into an insoluble infusible condensation product ("resite") by further treatment; if, however, the mineral acid is in excess of this amount but insufficient to produce the p "resite," then a non-hardening resin ("novolak") is obtained. When weak inorganic acids or organic acids are employed, a "resole" is obtained when slightly larger quantities than that required for neutralizing are used, and a "novolak" is obtained by using a considerable excess of acid. Suitable acids are hydrochloric, sulphuric, sulphur dioxide, oxalic, citric, etc.; or alkali bisulphates may be used. Suitable parent substances are phenol, cresol, &c., and formaldehyde or its polymers or hexamethylenetetramine. Examples of the production of the two types of resin are given.  Specifications 27096/08, 7284/15, and 129,993 are referred to.
