Title: Improved rubber composition
IPC: C08K3/26
Filed: 1935-10-15
Abstract: An electric wire or cable has a combustion-resistant covering comprising a rubber composition including at least 70 per cent by weight of the whole composition of lead carbonate.  Beneath this covering may be a layer of rubber loaded with selenium, and a layer of a good insulating rubber composition, and the said covering may itself be covered with one or more layers.  The rubber-lead carbonate composition may be obtained by mixing white lead powder with rubber, e.g. by first forming a master-batch containing 90 per cent of white lead, or the white lead may be mixed with water before addition to the rubber, or a paste of white lead may be mixed with rubber latex.

IPC: F15B1/26
Filed: 1955-10-06
Abstract: 797,296. Hydraulic apparatus. DOWTY EQUIPMENT, Ltd. Oct. 5, 1956 [Oct. 6, 1955], No. 28525/55. Class 69 (2). A pressurized reservoir for an aircraft hydraulic system comprises a reservoir chamber 16 containing a piston 13 connected to a piston 20 of smaller area working in a cylinder 22 which is telescopically mounted in a cylinder 19. This arrangement enables the length of cylinder 19 to be less than the total stroke of piston 13. Chamber 16 is connected to the inlet of a pump 52 and the discharge side of the pump is in communication with the cylinder 19 through a line 58 so that the liquid in chamber 16 is pressurized. The chamber 16 is provided with an air vent float valve which closes automatically if the reservoir is inverted. For charging and replenishing the reservoir a hand pump is coupled to an inlet 60 of a charging valve 59, and liquid is pumped into valve 59 whence it passes through a valve 66 into cylinders 19, 22, moving piston 13 through its full stroke and expelling air from the chamber 16 through the float valve. At the end of the stroke, pressure builds up until a relief valve 64 is opened, whereupon liquid enters chamber 16. Liquid is then expelled from cylinders 19, 20, and passes through valves 66, 64, to the chamber 16. A plunger 46 engageable by the piston 13 indicates when the chamber 16 is full. A glass 45 allows visual observation of the liquid level.

Title: Optical indpection
IPC: G01B11/16
Filed: 1971-06-22
Abstract: 1392448 Television NATIONAL RESEARCH DEVELOPMENT CORP 7 June 1972 [22 June 1971] 29213/71 Heading H4F [Also in Division G2] Comparison of an object with another object or with the same object after changes have occurred (e.g. in surface characteristics), is effected by forming respective images of the object(s) simultaneously or sequentially, using coherent light illumination, on a photosensitive screen, which is scanned to provide two video signals which are correlated. In the arrangement of Fig. 1, two surfaces 3, 4 the latter of which is a reference are illuminated by laser light 1. The "speckle" patterns representing the two surfaces (each pattern or image having such speckle or granularity due to random interferences) are superimposed and interfere at TV camera screen 7. Alternatively an image intensifier plus TV camera may be used, in which case pulsed operation to give a stroboscopic effect is possible. The video signal after one frame scan is stored in recording device 9, e.g. magnetic disc or tape, or a storage C.R.T. Surface 3 is then deformed, and the subsequent frame scan compared with the stored one by means of differencing circuit 10. Rectification in detector circuit 11 provides a unidirectional signal which can be displayed on C.R.T. monitor 12, scanned in synchronism with the camera. In a modification of the arrangement of Fig. 1, the video signals before and after a change, are both recorded, to enable more accurate synchronization of the two for correlation purposes than is possible in Fig. 1, but at the expense of real-time monitoring. In the arrangement of Fig. 2 (not shown), instead of a reference surface image being interfered with the test surface image, a smooth reference wavefront (direct from the laser) is used. Otherwise, operation as is in Fig. 1. In Fig. 3 (not shown), only the test surface is used, but two speckle patterns are provided by illuminating the surface from two different angles, and only in-plane displacements can be monitored. The comparison of a test surface to be checked against a "master" is possible using the apparatus of Fig. 4. An argon laser emitting 4965 Š and 4880 Š is used and a beam splitting and wavelength filtering system used in the camera, which has two screens 27, 28, so that the simultaneous video outputs, represent superimposition speckle patterns for two wavelengths. Differencing circuit 32, and detector 33 feed the display monitor 34. In the arrangement of Fig. 5 (not shown), two wavelengths of light are again used, but the camera has a single screen, in front of which is a two filter wheel, whose rotation is synchronized with the frame scan and the switching of the output on alternate frames to a delay device (41). A contour map of a surface may be obtained by using the apparatus of Fig. 1 to compare patterns from the surface obtained at two different wavelengths. The Figs. 4 and 5 arrangements may also be used for this purpose by the use of divergent radiation and selective blanking off of surfaces 21, 22.
