IPC: G01C19/44
Filed: 1920-03-17
Abstract: 149,312. Bonneau, E. E. J. March 17, 1920. Gyroscopic apparatus.-A clinometer has a reference member which is brought into the horizontal plane by causing coincidence of a direction datum observed in an optical device carried by a gyroscopic top having a vertical axis of rotation, with the axis of sight of a telescope. A spinning- top 3 carrying a mirror 4 is pivoted on a support 2 secured to a base 1 which constitutes the reference member and carries a telescope 5 with graticule 6, and a reflecting-prism 7. The optical arrangement is such that when the axis of the. telescope is parallel to the plane of the mirror 4, the image of the graticule formed by the telescope lenses, the prism 7 and the mirror 4, coincides with the graticule itself. The base 1 is hinged to a member 9 which is placed in contact with the surface whose inclination is to be measured, and is turned relatively to said member until the graticule 6 and its image coincide. The required inclination is then read off on the graduated arc 11.

Filed: 1923-03-22
Abstract: 222,156. Gray, W. March 22, 1923. Machine guns.-A fixedbarrel machine gun of the type in which the breechblock 24 is reciprocated by a rotary cam 50 has combined gas and spring means for rotating the cam during automatic working and independent means, such as a crank 62, for manually rotating the cam member. The cam is automatically rotated by a block 73 which is connected to the gas-piston rod 69 and has a pin engaging with a spiral groove 84 in a shaft 85 which drives the cam shaft 52 through a one-way clutch 92. On firing, the gases of discharge passing through a port 70 in the barrel 20 impart forward movement to the gas piston 68, thereby cocking a spring 78 and conveying idle movement to the shaft 85. When the cam 50 is freed by pressing the trigger 65, the spring 78 reacts to rotate the cam, the breechblock is retracted by the groove 49, and the firing pin 29 is cocked by a projection 51 on the cam. The firing pin is held cocked by a sear 38 which is pivoted to the breech-block so as to be automatically released when the breech-block returns to firing position and loads a cartridge C from the magazine 123. If a missfire occurs, a spring-controlled pin 76 on the block 73 engages a recess in a locking disc 57 to prevent rotation of the cam.

Title: Process for providing articles made of plastics with printed labels or coverings
IPC: B41M1/30
Filed: 1944-05-02
Abstract: A process of the type in which thermosetting plastic or thermoplastic articles are provided with labels or coverings during moulding, consists in laying the label, which consists of a reverse print on a thin sheet of absorbent paper, face downwards on the surface of the article while the latter is hot and tacky in the mould.  The curing process is subsequently completed, heat and pressure being applied to the label to embed it in the plastic. The plastic penetrates into the fibres of the label, making them transparent, so that the print becomes visible on the outside. The label may be previously impregnated with a solution of an artificial resin to render it transparent.  In this case, a lacquer, or other coloured material may be applied as a backing to the print.  Specification 562,573 is referred to.

Title: Improvements in or relating to shock absorber struts for aircraft
IPC: B64C25/62
Filed: 1933-03-22
Abstract: 416,857. Shock - absorbers. DOWTY, G. H., 17, Lansdown Crescent, Cheltenham, Gloucestershire. March 22, 1933, Nos. 8601 and 32787. [Class 108 (iii).] In a resilient strut for use in aeroplane landing - gear, &c. comprising two or more telescoping members which contract under compression against resilient resistance, a radially-acting friction brake or brakes are provided controlled by the load on the resilient resisting means, and slidable relatively to and with frictional bearing on two telescoping members. In one form, Fig. 1, internallyconed split collars 8, 9 are pressed by springs 6, 7 against a split triangularsection sleeve 10 so that with increase of pressure of the springs, the collars 8, 9 expand radially into contact with the telescoping member 1 while the sleeve 10 contracts on a rod or tube 5 fixed to the end of the member 3. An initial compression may be imparted to the springs to effect initial braking. The brake shown in Fig. 1 may be replaced by a brake comprising a single expanding wedge-shaped collar cooperating with a contracting conical sleeve. Such a brake is shown in Fig. 6, but a recoil spring 43, which may be a continuation of the main compression spring 7, is interposed between the contracting sleeve 41 and a collar 40 slidable on the stem 5. In a modification two braking elements 8, 9, Fig. 5, are expanded through springs 6, 7 against telescoping tubes 1, 3 by a plug 26 on the telescoping member 5 secured to the member 3 and a collar 27 abutting the tube 1, the plug 26 which may be replaced by a valve or other fluid-restricting device, having a bore 26A for hydraulic damping. In another construction, Fig. 4, on compression of the strut, a conical sleeve 32 is contracted on the stem 5 by a coned collar 30 secured to the end of the telescoping member 1 and a sleeve 37 is expanded into contact with the member 1 by a conical projection 36 fixed to the end of the stem 5, the collar 30 and plug 36 being separated by a spring 38. The stem 5 is secured to a piston 33 the space between which and the top of the telescoping member 3 is filled with fluid so that on compression of the strut braking is effected also by flow of the fluid through a passage 34 in the piston. Fluid-friction braking may also occur on expansion of the strut. The split annular members in each construction may be replaced by annular members having a helical division or by members of deformable material while the springs may be replaced by rubber or pneumatic devices.
