In drafting-apparatus, a cradle assembly for a pair of rollers each carrying an apron, comprises spaced walls 36, 38 and upper and lower guiding-members between them; each member is attached to a wall; one of the members is formed with an apron-reversing nose and a concave surface adapted to contact one of the rollers and is composed of two sections one moulded to one of the walls and one to the other, the two sections being adapted to interengage to hold them together and to maintain the walls in spaced relationship. In a preferred form, the upper member is in one section 44 integral with a wall 38, and having an internal cavity 80, and the lower member is in two sections 42, 34, one, 42, integral with a wall 36 and the other integral with the wall 38, the latter section being of triangular section to engage a triangular cavity 78 in the other section. The walls and members are moulded integrally from plastics material, the cavities being such as to leave surrounding walls of equal thicknesses to promote uniform cooling during moulding. Each member has a concave surface 60, 50 to engage the corresponding roller and a nose 56, 64 between apron-guiding and cleaning surfaces 52, 58 and 66, 62 respectively. The surface 58 is inclined upwardly away from the apron to allow for slivers of differing thicknesses and the edges between the apron-guiding surfaces may be chamfered as at 76 to facilitate passage of the sliver. When it is desired to change the separation of the noses to suit different slivers, the wall 38 is replaced by one in which the member 44 and the section 34 are differently spaced. The walls have recesses 48, 46 to engage the neck of the upper roller, and rounded rear edgs to guide the sliver and prevent it being caught between the walls and the rollers. In another form. Fig. 5, not shown, both members are in two sections joined by male and female unions.

Filed: 1974-11-27
Abstract: 1488718 Tape recorder SONY CORP 27 Nov 1974 [30 Nov 1973] 51416/74 Heading G5R In a tape recorder with control buttons 13 (eject), 14 (fast rewind), 15 (stop), 16 (playback), 17 (fast wind), 18 (record) and 19 (dubbing), the operation of play-back button 16 activates a safety mechanism 22 which prevents subsequent inadvertent operation of the record or dubbing buttons. When recording is required a further stop mechanism 24 is operated which stops the tape and via release mechanism 26 releases the safety mechanism so that the record button can be actuated to permit recording after the stop mechanism has been returned to its initial position. Operation of play-back button 16 moves a slide member 44 and its auxiliary member 58 to the right so that depression of either the record or dub buttons 18, 19 is prevented. In addition the button 16 also moves a slide member 82 to the left to condition the stop mechanism 24 for further operation. When recording is required handle 110 is operated to depress slide plate 112 so that a switch 134 is operated to stop the tape by energizing a solenoid (not shown) to lift the pressure roller from the tape. The plate 112 is locked in its depressed position by a plate 120 which can rotate to its locking position when slide member 82 has been moved by operation of the play-back button to condition the stop member. The lowering of the slide plate also acts via slide member 94 of the release mechanism to move the auxiliary member 58 relative to slide member 44 to dispose recesses 52 below the record and dub buttons to allow one of them to be depressed. With record button 18 depressed recording takes place when handle 110 is restored to its initial position unlocking slide plate 112 so that this is raised by spring 130 and the switch is turned off allowing the pinch roller to reengage the tape.

Title: Method of starting a stand-by engine-driven emergency generating set
IPC: F02N99/00
Filed: 1975-12-16
Abstract: 1507908 Starting emergency generator sets KLOCKNER-HUMBOLDT-DEUTZ AG 16 Dec 1975 [17 Jan 1975] 51475/75  Heading F1K An emergency generator is driven by an exhaust driven turbocharged reciprocating I.C. engine which is connectible to a flywheel through a first clutch for bringing the engine up to operating speed on failure of a power supply. The flywheel is driven through a second clutch by an electric motor powered by the power supply. As the turbocharger accelerates slower than the I.C. engine, the engine is starved of air and its power builds up slowly. In order to avoid slow power build-up an additive is injected during starting into the air induction manifold of the engine to increase the entropy of the exhaust gases and the acceleration of the turbocharger. To avoid overheating the additive has a higher latent heat of evaporation than the fuel employed and may be water, methanol, ethanol or a mixture of these.

[Also in Division H1] In a strip transmission line formed of three parallel, opposed dielectric sheets, metal coating on the inner surfaces of the two outer sheets forming the ground planes, and metal strips on either side of the centre sheet forming the centre conductor, the sheets are spaced from one another by layers of dielectric filling material bonded to the sheets and spaced laterally from the edges of the strips such that the field in the material does not exceed a predetermined value. As shown, two lines in parallel have central copper strips 6, 7, 6a, 7a formed on sheet 3 of epoxy material, and spaced from copper-clad fibreglass sheets 1 and 2 by the nylon impregnated fibreglass honeycomb material 8, 9. Radiating slots 10, 10a in the metal coatings constituting the ground planes form an antenna array; if the slots are formed in only one ground plane, metal foils stretching between the ground planes through breaks in the centre sheet 3 and filling material, on either side of the centre conductor, are provided, to suppress spurious modes produced by the asymmetrical line loading. The exposed ends of the structure may be shielded and sealed by conductive mesh with fibreglass and epoxy resin, the holes 15 formed throughout the honeycomb filling material 8, 9 permitting pressurization of the structure.

A device for use in the automatic machine  production of laminated products comprises a lid 30, a base 20, spring-biased hooks 40 on the lid for engagement with detent blocks 50 having chamfers 53 and secured to rods 90, a receptacle 70 having a check valve for insertion of pressure via conduit 72 and coupling 75 to a chamber 62 defined by the lid and a movable pressure plate 60, a release valve 80 operable by a pivotable lever 85, and a trip lever 96 for releasing the hooks by rotation of the rods 90 which are journalled in upright positioning members 93. The chamber 62 is sealed by a flexible diaphragm 63 as shown in Fig. 5. The members 93 contain bores 100 perpendicular to rods 90 which receive positioning pegs 102 for contacting and aligning the edges of the laminated product. The pegs are spring-biased toward the rods which have flat recessed portions 106 which allow retraction of the pegs simultaneous to unclamping of the hooks. The base may be adapted for various sizes of laminated product by means of insert members 110 (Fig. 6, not shown) provided with bores for spring-biased pegs 120 extending between the product and pegs 102. In a typical machine process (Fig. 2, not shown) a first panel skin is placed on the base 20 and passed to a foam applicator. A top skin is then applied automatically and a lid 30 is released to roll off a gravity roller conveyer (138) on to the base, the hooks 40 riding outwards against the spring bias and then snapping inwards to engage the surfaces 51 of the detent blocks. A nozzle is automatically inserted into receptacle 70 to admit pressure to chamber 62 and against plate 60 and the device then travels on a conveyer belt through an oven after which the pressure is released by means of a stop engaging the lever 85 and the hooks undamped and pegs retracted by means of a stop engaging the lever 96. The lid is elevated via a lift to the roller conveyer for return to the clamping station and the base and laminated product pass to a separating station, the base also being returned to the assembly station via a gravity roller conveyer.
