Title: Latch mechanism for a lift truck
IPC: B66F9/08
Filed: 1973-05-04
Abstract: 1421352 Mast for lift truck KNICKERBOCKER CO 4 May 1973 [8 May 1972] 53252/74 Divided out of 1421351 Heading B8H [Also in Division E2] In a telescopic mast for a fork lift truck, a latch is mounted on the uppermost or inner section 32 for locking the inner section first with the lower or base section 28 and then with the lifting carriage 22 as the latter is elevated along the mast. The latch comprises a plate 72 with a central slot 110 through which a pin 112 passes to loosely pivotally mount the plate on the inner mast section 32. The plate has a pair of convex surfaces 114, 116, which meet at an apex 136 for co-operation with a roller 106 by which the plate is biased into end positions. The plate further has recesses 124, 126 which co-operate respectively with latch actuators 128, 130 mounted respectively on the lift carriage and on the base section 28. In operation, with the mast in its retracted position, the actuator 130 is in engagement with the recess 126, Fig. 8, and the lifting force applied on the inner mast section 32, by chains (35), Fig. 2 (not shown), maintains the latch in the shown position to lock the inner mast section 32 to the outer mast section 28. When the lift carriage is raised the actuator 128 engages in the recess 124 and due to the greater leverage thereof will pivot the plate 72 to the position of Fig. 10 whereat the carriage 22 is locked to the inner section 32 and will move therewith during any subsequent raising of the mast.

Abstract: 1335712 Measuring the thickness or basis weight of materials INDUSTRIAL NUCLEONICS CORP 11 Nov 1970 [17 Nov 1969] 53736/70 Heading G1A A beta ray gauge for measuring the basis weight (mass per unit area) of material such as paper tissue comprises a source head 10 employing beta energy shifting or softening reflective surfaces 82, 90 and 92, Fig.2, spaced apart from a detector head (12), Figs.1 and 6 (not shown) so as to form a gap through which the material can be positioned or moved, the source consisting of radioactive Krypton gas contained in an annular cavity 40 so that beta rays leave the source via a stainless steel window 42, Fig.3, to be incident on the reflecting surfaces 82, 92, and 90 which shift the spectrum of the emitted beta rays to a lower energy level and deflects the modified rays through circular aperture 50 so as to impinge upon the material being investigated. The reflecting surface 92 is removable and is mounted on a head 60 at one end of a plunger rod 62 supporting a soft iron armature 70 partly inside an electric solenoid coil 72, so that on actuating the coil 72 the plunger head 60 and reflecting surface 92 can be pulled against the bias of spring 67 from a position in which the aperture 50 is closed Fig.2 to a position in which the reflecting surface 92 is aligned with reflecting surface 82 as shown in Fig.3. Both the source head 10 and the detector head are maintained at a constant temperature by means of heaters 110 and 120 Fig. 6 (not shown) monitored by thermistors. An associated control circuit Fig.7 (not shown) including the thermistors is disclosed. The gap between the two heads is kept free of dust and at a constant temperature by means of a blower 132 and a constant temperature heater 130 arranged so that hot air is blown via ducts 135, 136, and 138 as shown by arrows, across the face 144 of the source head.

Title: Process and apparatus for recovering condensible components from a gas stream
IPC: B01D53/04
Filed: 1969-11-05
Abstract: 1,261,750. Recovering condensibles. BLACK SIVALLS & BRYSON Inc. 5 Nov., 1969 [5 Nov., 1968], No. 54345/69. Heading B1L. In a continuous cyclic process for recovering condensibles e.g. methane from a gas stream a regenerated adsorbent bed has its undesorbed condensibles swept out by the main gas stream and re-adsorbed in another bed. During the first phase of a three phase cycle the main feed gas is fed from line 10 and liquid separator 13 (via heavy type line flow path) to adsorbent bed 16 wherein condensibles are adsorbed. Stripped main gas passes to bed 18 which becomes relatively cool. The gas emerging passes via lines 42, 72, heat exchanger 74, and lines 76 to exit 80. Regeneration gas cycles through line 84 heat exchangers 74, 88, heater 94, line 98 and bed 20 to desorb the condensibles. The emerging gas stream passes via lines 116, 124, 126 to atmospheric cooler 128 and condensible separator 136. The regeneration gas is recycled via line 140. In the initial stages of the next phase the main feed gas passes through previously desorbed hot bed 20 and sweeps out any undesorbed condensibles. The gas then passes via lines 44, 70, 72, 76 and 46 onto the now cooled bed 18 to adsorb the condensibles. The emergent gas passes out via the line 80. In the latter stages of the phase the feed of the main gas stream is switched from bed 20 to bed 18 so that condensible adsorption takes place. The stripped gas passes to bed 20 to cool it and thence exits at line 80. The regeneration gas still passes through the bed 16. In the last cycle-completing phase the beds are switched so that the previously cooled bed is adsorbing the previously heated bed has it undesorbed condensibles swept out and the previously adsorbing bed is regenerated. Valves 148, 146 are used for volume control.

Abstract: 1491859 Glassware forming machine EMHART INDUSTRIES Inc 22 Nov 1974 [23 Nov 1973] 54389/73 Heading ClM An individual section glassware forming machine has in each section one or more blank moulds at a station A and a second station B at which further processes are carried out, the parison being transferred between the two stations by means of a carriage 18 which is linearly reciprocable longitudinally of the section. The carriage carries neck ring mould sections 62 for gripping the parison which are movable towards each other by means of a rack and pinion device 76, 78 operated by rotation of the rails 20 on which the carriage 18 moves, when, as shown, the station B and a third station C are constituted by blow moulds. The carriage also carries blowhead and tong devices 32 of the type described and claimed in Specification 1,491,860. The blank mould comprises a vertically movable one-piece mould element 58 and a pair of horizontally movable intermediate mould sections 60. In use, the parison is shaped by a plunger 38 after which the intermediate mould sections 60 are opened and the mould element 58 lowered. This allows the parison, gripped by the neck ring mould 62, to be moved by the carriage 18 to the two-part blowing mould at station C. The return movement of the carriage brings the blowhead 32 over the mould. After blowing a second forward movement of the carriage moves the parison, carried in the tongs of the blowhead, to station C while simultaneously moving a second parison to station B gripped by the neck moulds. A second blowing operation is carried out at station C using a second blowhead and a further forward movement of the carriage.

[Also in Division H1] A method of bending a swaged sheathed electrical conductor having an intermediate compacted insulation comprises forming a planar arcuate bend in the conductor, deforming the bend by applying a force parallel to the bending axis and restraining the bend to prohibit radial deformation with reference to the bending axis simultaneously with deforming to thereby eliminate fissures in the compacted insulation the restraining force being continuously exerted over one half of the conductor surface at the bend and the force being applied by a member having a planar surface engaging the unrestrained surface of the conductor to cause flattening of a portion of the conductor assembly. The conductor comprises an outer sheath 11 of stainless steel or wrought heat resisting nickelbase alloy, an electrical conductor 12 of copper, nickel or iron and an intermediate insulation portion 13 of a ceramic refractory oxide e.g. magnesium oxide or a mixture of magnesium oxide and glass. In the manufacture of the conductor the insulation 13 is applied as bored beads strung on the conductor 12 which is then positioned in the sheath 11 and the assembly is swaged to reduce the outer diameter and to compact the particles of the insulation. The conductor is bent in a die 20 (Fig. 3) and its cross-section changes from circular to ovoid. A compression member 26 is pressed against the conductor in the die to form a flat 35 (Fig. 6B) or flats 33, 34 (Fig. 4B). A 10 to 20 per cent reduction in diameter eliminates any fissures formed in the insulation during bending of the conductor. The method can be applied to multiple conductor assemblies.
