Abstract: 1405460 Road line marking apparatus L EIGENMANN 26 July 1972 [30 July 1971. 23 Oct 1971] 34921/72 Heading E1G Road line marking apparatus comprises a vehicle 20, apparatus 22 for laying a coating layer and a device 24 for laying a marker tape 14 and pressing it into the surface 10 of the coating, the vehicle having bulk storage means for the coating composition, a mandrel for a plurality of tape spools 46, and tape guide means 48 selectively positionable above each spool. The tape 14, Fig. 4 is pressed into the surface 10 of a hot layer of coating composition which is wider than the tape to provide edge-protecting shoulders 12". Heat and/or chemical action from the coating causes rapid setting of adhesive on the tape. The laid tape and shoulders may be temporarily covered during setting by paper or plastics sheet 16 from spool 30, the sheet being removed-e.g. by traffic, by rewinding, by separate burner vehicle or (as shown) by a trailed burner 36. The tape laying device 24 has pressing rollers 26, 28 and may incorporate means for applying adhesive to the tape. As shown the vehicle 20 tows both the device 24 and the coating apparatus 22 and has a forwardly-extended sight 40.  In the coating apparatus 22, Fig. 7, a pump 82 driven by a road wheel 86 supplies composition from the hose 68 through a heat exchanger 88 to a nozzle 80. The road surface s is dried and heated by a first burner 62 having a double-walled diffuser cooled by an air supply 76 which is subsequently used to heat the nozzle 80. The exchanger 88 is heated by a second burner 94, both burners being controlled by a valve 100. The pump 82 has a by-pass valve 98. Parts of the apparatus shown may be duplicated to allow use of two-component compositions which are mixed during laying. Examples of compositions are given.

Abstract: 734,180. Pianofortes. BALDWIN CO. Dec. 15, 1953, No. 34941/53. Class 88 (2). [Also in Group XXIII] A wrest plank for a piano is made of crossgrained resin-bonded plies of hard wood such as sugar maple, the thickness of the plies being in the range 1/8 to 1/28 inch. The ratio of hole diameter to pin diameter is between 0.925 and 0.96. The resin is preferably chosen and applied so that the plywood has a specific gravity between 0.72 and 0.87. The plywood may be either hot pressed or cold pressed. The resin used for hot pressing may be a thermosetting phenol-formaldehyde resin condensate carried to the point of an A stage resin, a urea formaldehyde resin or a resin of the acrylonitrile or melamine type. For cold pressing, condensation products of resorcinol and formaldehyde may be used with a catalyst, if necessary. In one example, two separate sets of 19 plies of 1/28 inch sugar maple are cooled with adhesive and pressed between platens heated to 300- 310‹ F. for 25 minutes. After cooling, the two structures are bonded together by inserting between them one 1/28 inch ply of the maple coated with a resorcinol-formaldehyde adhesive and a catalyst. The plywood is left to set and then cut to shape.

In one embodiment (Fig. 1, not shown) two emitters (2, 3) in the form of separate filaments are encased in a non-neutron responsive collector (1) of nickel alloy or stainless steel; one emitter (2) is made of γ-responsive material (e.g. a nickel alloy), while the other (3) is made of a material responsive to both neutron and γ radiation (and is preferably of the same atomic number as the material of the one emitter), e.g. cobalt or vanadium. In use, by connecting respective output leads (9, 8) to inputs of a differential amplifier, an indication of neutron flux independent of γ-flux is obtained. In another embodiment (Fig. 2, not shown) a composite rod emitter (15) comprises alternate sections (19, 20) of two different materials whose γ sensitivities, relative to the collector, are of opposite polarities, at least one of the materials also being neutron-responsive.

Title: Machine for the stapling of folded booklets on the back folds thereof

Abstract: 841,162. Stapling machines. MULLER, H. Nov. 21, 1957 [Dec. 12, 1956], No. 36295/57. Class 89(3) [Also in Group XVI] A machine for stapling folded booklets along the back-fold thereof comprises a driven-conveyer for conveying folded booklets past a stapling device, when the stapling device is mounted on a carrier to which is imparted a horizontal reciprocating motion by means actuated by the means which drive the conveyer, and stapling device is given a simultaneous vertical reciprocating motion, to move it into operative and inoperative position, by lever-mechanism also operated from means which drives the conveyer. As shown the machine comprises a main-shaft 2 on which are mounted sprockets 3 for driving endless-conveyer-chains 4. The shaft 2 is driven from a motor 1 by a belt-andpulley drive 9. The chain 4 carries dogs 5 for pushing assembled-sheets 6 along a saddle-shapedcarrier 7. Crank-pin 12 is attached to the pulley 9 and is connected through a link 13 to the carrierbody 14 of a stapling-head 15. The body 14 is guided in guides 16, 17, for to-and-fro-movement parallel to the conveyer 4. The pin 12 is also connected by a rod 22 to a lever 20 mounted in a bearing 23. Idly-mounted on the pivot-bearing 23 is a bell-crank 21, one arm of which engages a slide-guide 24 of the stapling-head 15, and the other of which carries an electro-magnet 26 having an armature 27 capable, when the electro-magnet is energized, of engaging a cam 29 on the lever 20 so as to couple the bell-crank 21 rigidly to the lever 20, and thus cause up-and-down oscillation of the stapling-head 15 on the carrier 14. The distance between the dogs 5 is equivalent to one revolution of the pulley 9. The electro-magnet is connected in circuit with a feeler 28a, which operates a switch 28 when the sheets to be stapled contact the feeler. At this time the carrier 14 is moving at the same speed and in the same direction as the conveyer, and the stapling-head is moved downwardly to affect stapling when the electromagnet is energized.
