Abstract: 603,368. Two-part couplings. DAVIS & SON, DERBY, Ltd., J., and DAVIS, W. H. Oct. 19, 1945, No. 27452. [Class 38 (i)] [Also in Group XXXVII] A two-part coupling for joining two lengths of armoured cable 16, e.g. for use in coal-face signalling in mines, incorporates a short-circuiting switch and comprises plug and socket portions 10, 11 respectively, the former fitting within a flange 11a on the latter, said flange carrying locking pins 12 which by rotation of a locking ring 13, are made to engage an annular groove 10a in the plug to lock the coupling together. The conductors 18 of each length of cable are connected to a contact ring and segment, 19a and spring- loaded pins 20a carried by insulating plates 19, 20 in the plug and socket respectively. The supporting brackets 22 for the pins 20a carry leaf-spring contacts 23 which are adapted to be engaged by spring-loaded press-buttons 24 mounted in the socket body. Pressure on either of said press-buttons causes the leaf springs to engage one another, thereby shortcircuiting the cable conductors. A single pressbutton or more than two may be employed. The cable armourings are clamped between the ends of the coupling and plates 15 secured to the coupling by threaded studs 17.

Title: Improvements in or relating to the stapling of the products of rotary printing machines
IPC: B41F13/66
Filed: 1927-10-18
Abstract: 304,264. Quick, C. G. Oct. 18, 1927. Delivery apparatus ; stapling and stitching devices. - The products of a rotary printing- machine having printing-plates wherein the columns of type extend circumferentially around the printing-cylinder are stapled by rotary stapling-mechanism which forms staples disposed longitudinally with respect to the stapling-cylinder, means being provided for so directing the products from the printing- machine to the stapling-cylinder that the staples are inserted parallel to the columns of type on the products. The printed webs 1<a> - - 1<h>, Fig. 1, pass from the printing-machine between rollers 2, 2<1> to form an associated web 1 which is cut into sheets by a cutting-cylinder 3. The sheets are folded in known manner by rollers 4, 5 coacting with a folding-blade on a folding-cylinder 6 with which the cutting-cylinder co-operates. The folded sheets are then fed between upper and lower conveyer tapes 7, 8, the upper tapes being passed over a roller 9 mounted on an arm 10 which is rocked periodically to move them away from the lower tapes when the loading edge of the sheets impinges against stops 11. Simultaneously, a lateral edge of the sheets is caught between a second folding-cylinder 12 and a rotating member 13, the sheets being thereby drawn in a direction at right-angles to their former movement. The cylinder 12 co-operates with the rotary stapling-cylinder 14 which inserts the longitudinal staples, the sheets then passing between rollers 15 - - 18 to form a second fold in known manner. The sheets are finally delivered to a magazine delivery and thence to delivery belts.

Title: Improvements relating to lasers
Inventor: CHILCOT ARTHUR LESLIE
IPC: H01S3/086
Filed: 1969-05-31
Abstract: 1,256,118. Lasers. FERRANTI Ltd. 13 May, 1970 [31 May, 1969], No. 27706/69. Heading H1C. A laser resonator mirror is supported by a plastically deformable mount which allows initial alignment. Fig. 1 shows the mirror 17 at the end 16 of a tubular mount 13 connected to the base-plate 10 of a gas laser. The mount 13 has a circumferential groove 18 which allows the end 16 to be tilted relative to the laser optical axis. The adjustment is carried out using a jig 20, Fig. 2, which may be placed over the tubular mount and which carries screws 22 by which the grooved portion of the mount may be deformed until optimum alignment is achieved. The mount should be of a ductile material such as copper to minimize any backlash due to elastic deformation. Instead of a grooved portion, the mount 13, Fig. 3, may comprise a pair of coaxial tubes 14, 16, interconnected by a lead annulus 18 which may be deformed by removable screws 22, the outer tube forming the adjusting jig. The tube 16, which carries the mirror 17, may be the inner tube of the pair, Fig. 4 (not shown), which allows a smaller mirror to be used and protects the alignment against accidental blows. Any of the above mounts may be adhered directly on to the end of a gas laser tube or on to a Brewster window, Figs. 5-8 (not shown), the use of a Brewster window having the advantage that a gaseous infra-red absorber such as methane may be contained within the tubular mount. The mount may be used with solid, liquid or gaseous active media, and one would normally be used for each resonator mirror.

Abstract: An aggregate for use in concrete or in an asphalt road surfacing composition is formed of grains of devitrified glass containing at least 60% SiO2 and 20% CaO, the balance comprising other oxides as used in glass making and serving as fluxing agents.  Part of the CaO may be replaced by an oxide of Be, Mg, Sr, Pb.  The composition may be obtained by fusing a mixture of sand, chalk or lime and dolomite or foldspar.  The molten glass is devitrified by quenching in water and reheating or by casting and cooling slowly and crushing.  The particles may contain cavities depending on the type of melting furnace used. Mineral particles which do not become completley vitrified may be added to the molten glass before discharge.  A road surfacing composition may contain:-30% devitrified glass grains; 58% other stone material; 5 1/2 % filler; 6 1/2 % asphalt.
