Abstract: 978,702. Loading and unloading pallets; load-handling devices. H. SCHAEFER. Feb. 16, 1962 [Feb. 25, 1961], No. 6196/62. Headings B8C and B8H. Bottle crates in stacks are loaded on or unloaded from pallets by means of a support frame 4, mounted on a trolley 3, the frame 4 carrying a member 7 having support arms or prongs 18. The member 7 is connected to the frame 4 by articulated linkage 5, 6, and may be raised or lowered relative to the frame by means of a ram 14. Stacked crates are delivered on a roller way 16; the trolley 3 is advanced to engage the lowermost crate of the stack by the prongs 18; the ram 14 is operated to lift the stack; the trolley is advanced towards a pallet 20 on a track 19; the cylinder 14 lowers the stack; and the trolley 3 returns, each step being controlled automatically by mechanical, optical or electric sensing means. A stop is used to hold back subsequent crates on the roller way 16 during the operation. Modifications.-The support arm may swivel and the articulated linkage be arranged to tilt the member 7 in its raised position, Fig. 3 (not shown). The lifting device may have hooks arranged one above the other on the member 7 which engage in openings in the sides of the crates, a pronged device, as in Fig. 1, being carried on the opposite side of the support arm, Fig. 4 (not shown). Three stacks side by side may be lifted together, Fig. 5 (not shown). The hooks may be of V-shape, Fig. 6 (not shown). Two or more stacks of crates may be moved from opposite directions, Fig. 8 (not shown) by means of two lifting mechanisms arranged opposite one another. As shown in Fig. 9, three crank drives 44, 51 and 57 may be used to effect horizontal and vertical movement of the lifting mechanism. A bolt 50 is secured to an endless chain 51 which is actuated so that the bolt 50 travels to either of two positions 50<SP>1</SP> or 5011 thereby moving in a vertical guide 49 and causing the trolley 3 to travel towards the crate stack. The crank drive 44 moves a carriage 42 for the support arm 4<SP>1</SP>, and the drive 57 raises the member 7. A further guide wall may be mounted on the support wall by means of parallelogram linkage, Fig. 10 (not shown).

Title: Improvements in machines for spinning rayon or other synthetic filaments
IPC: D01D5/00
Filed: 1943-04-19
Abstract: <PICT:0568393/IV/1> <PICT:0568393/IV/2> An enclosed type of machine for spinning rayon or other synthetic fibre, by the wet or dry method, has means for preventing the escape of noxious gases into the spinning room, and for economising in the power consumption needed to operate the vapour exhaust fan associated with the machine.  The spinning machine, having on each side a plurality of spinning stations with filters 2, spinnerets 4 and upper and lower godets 5, is enclosed by a plurality of sashes 6 hingedly mounted at their upper ends by parallel arms 11.  A plurality of vapour ducts 20, connecting with a common exhaust duct 21 and exhaust fan, are provided with dampers 24 mounted on a common shaft 25.  Upon opening the sash 6 one of the arms 11 turns the lever 40, mounted on shaft 38, and thereby actuates a cam 33 which causes a valve 30 to be opened and allows air to pass along the air line 29.  The air depresses a piston in air-motor 26 and thereby opens the damper 25. When the last of the sashes 6 is closed torsion springs on shafts 38 cause the shafts to return to their original position whereupon air valve 30 is closed, the air-motor piston recedes, and dampers 24 are closed.  All the dampers may be operated by one air-motor or each tributary duct may be provided with a separate air-motor and control-valve.  In a modification the arms 11 are caused to close an electric circuit which is adapted to open the dampers or, alternatively, the arms may contact a circuit including a capacitance relay which is arranged to effect opening of the dampers.  In another modification a push-button switch is provided p  for each sash so that opening a sash permits a spring to operate the pushbutton and close an electric circuit which, in turn, opens the dampers.

Abstract: 853,136. Electronic data-storage devices. BELL PUNCH CO. Ltd. Feb. 19, 1959 [March 3, 1958; May 21, 1958], Nos. 6797/58 and 16382/58. Class 106 (1). The count in a multi-cathode counting tube is displayed on an indicator tube having a number of cathodes each shaped as a decimal digit (see Fig. 6), by suitable coupling between corresponding cathodes of the two tubes. Fig. 1 shows one such coupling between counting tube 1 and indicator tube 2, the supply for tube 1 having an A.C. component introduced from 13. Each pair of cathodes is coupled as shown so that the alternating component of voltage at the cathode registering the count in tube 1 is rectified to lower the potential at 29 and attract the discharge in tube 2 to the corresponding cathode. Components 22 and 25 ensure that tube 2 passes current intermittently (in the manner of a relaxation oscillator) so that the mean current may be low enough to allow correct rectifier action at 23 while instantaneous current is high enough to illuminate the full cathode areas. Fig. 3 (not shown) illustrates a modification in which the intermittent action of tube 2 is effected by use of an A.C. component at 27 derived from source 13. Fig. 6 shows a coupling arrangement in which the negative swing at the left-hand end of transformer secondary 38 causes a lowering of potential at the cathode 20 of tube 2 corresponding to the count in tube 1 (the remaining cathodes of tube 1 being biased back until diodes 37 cease to conduct) while the anode 5 is being raised in potential through coupling 42, 43 so that current then passes to the appropriate cathode; on. the reverse swing the glow in tube 2 is extinguished. Fig. 7 (not shown) illustrates a modification of Fig. 6 using a phase-splitter valve instead of the transformer.
