Title: Improvements in nailing machines
IPC: A43D79/00
Filed: 1938-11-21
Abstract: 521,518. Nailing. O'DELL, A. E. (Maschinenfabrik Moenus Akt.-Ges.). Nov. 21, 1938, No. 33807. [Class 89 (iii)] A nailing machine comprises a separator which is moved lengthwise in steps to receive several nails from each of a number of raceways, and then is tilted to transfer the entire gang of nails, point upwards, to the nail tubes. As shown applied to a heel-attaching machine, a separator . 23 provided with four groups of pockets a-d for receiving four nails from each of four raceways 21, is carried by a shaft 24 mounted for axial and tilting movement at the foot of the raceways. The shaft is actuated by a cam disc 60 adapted to be driven through a one-revolution clutch. Axial movement is imparted by a cam lever 62 and a cam groove of such form that the separator first moves slightly to the right, Fig. 6, to align the pockets a with the raceways, and then moves to the left in steps to align the pockets b-d successively with the raceways. The groove also imparts a shaking movement to the separator at each step, to prevent sticking of the nails in the raceway. The tilting movement, to carry the nails from the raceways to the nail tubes 15, follows the last axial step, and is imparted by a cam lever 70 and a toothed segment 84. Both cam drivers include yielding means permitting slip in case the separator should be obstructed. The clutch is engaged by a roll 40, carried by the loader block of the machine, as it moves from nail-receiving to nail-delivering position. The roll 40 rocks a lever 42 so that a roll 43 engages and moves a slide 44, Fig. 8, splined to the shaft 49 which carries the cam disc 60. The slide carries a pawl 51 which is thus brought into driving engagement with a constantly-driven ratchet wheel 48. The drive is disengaged after one revolution by the re-entry of a roll 52 on the slide into a notch in a fixed disc 54. Premature re-entry is prevented by a latch 55. During the axial and tilting movements of the separator, the nails are retained in the pockets by plates 64 which partake of the tilting, but not the axial, movement of the separator. The shaft 24 also carries a bar 26 arranged above the separator and fitted with individually-adjustable stops 27 whereby any of the pockets -may be closed against the entry of nails to give any desired nailing pattern. A spring-pressed plate 90 carries fingers 92 adapted to close the ends of the raceways when the separator is tilted, the plate being moved by abutments 93, 95 on the separator when the latter is at either end of its stroke. The nails are supported and guided, while the separator is tilting, by an adjustable curved plate 74. The nails are conducted by the tubes 15 to a footplate with which the loader block registers when in nail-receiving position, the footplate and block being fitted with nailreleasing shutters. The block is movable by hand, and is biassed to both end positions by a spring.

Abstract: 1284636 Control systems for D.C. arc welding apparatus TOA SEIKI K K 13 July 1970 [26 July 1969 13 Aug 1969 29 Dec 1969] 33866/70 Heading H2H A direct current arc welding apparatus supplied from a single phase A.C. source by way of a rectifier device is provided with a capacitor which is charged when the output voltage of the rectifier device is relatively high and which discharges into the arc when the output voltage of the rectifier device is comparatively low, thus preventing extinction of the arc when the output voltage of the rectifier device drops to zero. A D.C. arc welding apparatus of the type having a consumable electrode continuously fed towards a workpiece is connected across the output terminals V 3  of a rectifier bridge 14 comprising a pair of diodes and a pair of thyristors 14a, 14b. A capacitor 18 in series with a saturable reactor 17, the saturation of which is set by a potentiometer 47 in a control unit 24 to control the charging rate of the capacitor 18. Thus the capacitor 18 receives a charge during the unsmoothed output half-cycles of the rectifier bridge 14 until the voltage value of the half cycle drops below the voltage to which the capacitor 18 has become charged. The capacitor thereupon discharges into the arc formed between the electrode and workpiece, the change in direction of the current in the working winding of the saturable reactor 17 altering the effect of the reactor compared with that during the capacitor charging phase. Thus, the capacitor energy maintains the arc during the periods in which the output voltage of the rectifier bridge 14 is below the arc voltage. The A.C. input voltage is regulated by a device 13 comprising an auto-transformer and the waveform of the output of the rectifier bridge 14 is shaped by a circuit device 23 which controls the firing of the thyristors 14a, 14b so that the waveform is of a trapezoidal form. In other embodiments the rectifier device 14 is a half wave device, the reactor 17 may be a single winding device which is not saturable or the supply from the A.C. source 11 to the transformer 12 may be controlled by a pair of backto-back thyristors.

Title: Production of 5-hydroxymethyl furfural
Filed: 1957-11-05
Abstract: 5-Hydroxymethyl furfural is obtained by a process comprising heating an aqueous solution of glucose, fructose, invert sugar, fructosans, sucrose or hydrolysed wood or starch to a temperature in the range 250-380 DEG  C. for a time not in excess of 2 minutes but sufficient to form 5-hydroxymethyl furfural.  In some cases it is desirable to use an acid catalyst, e.g. levulinic acid. Preferably the process is carried out by continuously passing the sugar solution into a reactor and continuously withdrawing the reaction product.  During the reaction a tar which is soluble in many organic solvents, e.g. furfural, ethyl acetate, formamide, dimethyl formamide, and dimethyl sulphoxide, may be formed.  In view of the instability of 5-hydroxymethyl furfural it should be removed from the reaction mixture as quickly as possible, for example, by operating continuously in the presence of an extractive solvent such as furfural whereby the aqueous sugar solution and furfural are pumped co- or counter-currently through the reactor.

Abstract: 521,855. Tempering glass. PILKINGTON, BROS., Ltd:, MITFORD, J. B., and SHAVER, W. W. Nov. 26, 1938, No. 34484. [Class 56] A method of tempering glass consists in passing the heated glass along a path in a liquid bath in which there is a descending temperature gradient, the upper temperature being high enough to avoid crizzling of the glass while the lower temperature is adapted to give the desired degree of temper. The liquid 1, Fig. 1 may be stored in a vertical container 2 the upper portion of which is provided with heating-channels 3, 4 while the lower portion is provided with similar channels 5, 6 that may be used either for heating or cooling. In use, the heated glass articles are dropped into the bath and fall into a basket 11 by which they are withdrawn from the bath. With articles of ordinary soda-lime glass, the liquid may consist of the molten eutectic mixture of sodium and potassium nitrates. The temperature of the upper part of the bath is maintained at about 450‹ C., and that of the lower part at about 250‹ C., the depth of the bath being about 30 inches. In a modified construction, the articles are withdrawn through an inclined channel that communicates with the bottom of the container 2. In another construction, the heated articles are placed in baskets 11, Fig. 3, suspended from a rotating frame 21 by which they are carried through liquid in a U-shaped container 15. As the baskets emerge from the liquid, they are tilted by a member 37, to discharge the tempered articles into a water trough 39. By using four uniformly-spaced baskets instead of the twelve shown, the articles may be dropped into the liquid so as to fall into a basket which is already at some depth in the bath. Specifications 477,585, 505,626, 505,627 and 507,170 are referred to.

Abstract: 759,735. Multi-storey garages. MAIER, E. Nov. 30. 1954 [Nov. 30, 1953], No. 34650/54. Class 20(1). [Also in Group XXX] Vehicles placed in carriers or plat. forms 15 suspended from the link joints 4 of endless chains 2 are transported along and from floor to floor in a garage building 1. The chains 2 have rollers 6 running in guide rails 5 which have curves leading from one floor to another of radius greater than half the height of one storey and also have inverse curves 11 leading the height curves back on to the level of the next floor. The curves of the rails are elliptical. The vehicles are restrained from bumping each other by being suspended at each end of long rigid links forming the conveyer chain. To take up temperature variations in the endless chains 2 one section 12 of the guide rail 5 is resilient and shiftable by a piston in a cylinder 13 or by a spring. The chains 2 are pulled along by a short endless auxiliary chain 8 with depending triangular catches spaced to engage the pins 4 of the main chain 2. Each vehicle is driven on to a conveyer 3 at the entrance 15 after the chain has been. stopped by a switch on the carrier, when at 15, whereby through a relay 19, Fig. 6, the drive motor 10 is stopped at that position. Depression of the appropriate button 41 restarts the motor to allow a vehicle to be driven on to a particular carrier 3 when at the entrance 15. Instead of a push button an appropriate key 16, Fig. 6, bearing the number of the particular carrier is inserted in the same numbered keyhole 17 whereby switch 18 and relay 19 on its output side supplies the motor 10 and two smaller motors 22 controlling gates 24. The input side of relay 19 is connected to push button switches 25 outside the gates 24 and to a number of switches 21 each of which corresponds to one of the carriers 3. Then the motors 22 first push the locking bolt 23 into engagement with the carrier 3 standing at the entrance. The garage entrance could be sunk below ground level as in Fig. 8 (not shown).
