Title: A process for the removal of wax and the like from fluid compounds of hydrocarbons
IPC: C10G73/06
Filed: 1937-09-10
Abstract: 507,646. De - waxing oils. AKTIEBOLAGET SEPARATOR-NOBEL. Sept. 10, 1937, No. 24705. Void. Convention date, Sept. 28, 1936. Drawings to Specification. [Class 91] Mineral oils are de-waxed by heating with a solvent, if necessary under pressure, to such a temperature that all the fluid hydrocarbon and at least some of the wax is dissolved, whereupon the temperature is lowered until the difference in solubility between liquid waxy and fluid hydrocarbons is sufficient to form a separate layer of wax which is in liquid form, which layer is then separated. The solvent used is such that the oil solution is either heavier than the heaviest wax or lighter than the lightest wax. Solvents specified include methyl or methylene chloride, ethanol, isobutyl alcohol, trimethyl carbinol, furfurol, butyraldehyde, disobutyl ketone, methyl formate or acetate, acetol, or mixtures of these. For example, a lubricating oil is heated to 65‹ C. with a mixture of methyl alcohol, methyl formate, and methyl ethyl ketone in a closed vessel. A small amount of water may be added. The mixture is then cooled to 38‹ C. and the separated liquid wax is removed by centrifuging. The oil-solvent layer may be further cooled and the liquid wax again separated. The final dewaxed oil may be freed from solvent by distillation or cooling to a low temperature.

Title: Improvements in carrying out exothermic catalytic gas reactions and in apparatus therefor
IPC: B01J8/06
Filed: 1927-09-23
Abstract: 303,192. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 23, 1927. Catalytic apparatus.--In apparatus for exothermic catalytic gas reactions the catalyst is contained in a number of tubes closely packed together to form a bundle, the interspaces between the tubes being so restricted relatively to the cross section of the tube, and having regard to the density of packing of the catalyst contained therein, that the incoming gas which passes first on the outside of the tubes travels at a higher velocity than it does within the tubes. The tubes are preferably tapered at one or both ends, their tapered ends being inserted in a tube-plate, as shown in Fig. 1, to allow gas to pass readily to all parts of the bundle. The tubes in some cases may be polygonal in cross-section whereby the spaces between, them may be considerably reduced as compared with those of circular crosssection. If round tubes are employed the spaces between them may be partly occupied by inert fillers such as iron rods. In another arrangement the walls of polygonal tubes may be in actual contact, some of the tubes being left empty or filled with an inert filler and so connected to the gas supply that they serve as heat exchange devices. In an arrangement shown in Fig. 3 the gases flow in the same direction both within and outside the tubes, being returned, after their passage outside the tubes, to the inlet end by a tube z.

Abstract: 425,237. Coin - freed table game apparatus. HORTON, J. F., 55, Bustleholme Lane, Charlemont, West Bromwich, and DAVIS, C. T., 153, Compton Road, Wolverhampton. Sept. 13, 1933, No. 25307. [Class 132 (ii)] [See also Group XVIII] In a game such as snooker, wherein balls are projected into pockets to effect scoring, means are provided to lead pocketed object balls to a storage compartment from which they may be freed by coin-operated means, whereas the larger cue ball is always available for replay. Inclined shoots 5 lead pocketed balls to a slot 6, Fig. 3. The object balls 9 fall through this slot into a chamber 7 and roll onto a pivoted member 12 coming to rest against a barrier 10<a>. The cue ball 8, however being larger than the object balls, rolls along the top of the slot 6 on to a grooved guide 10 and falls into a trough 11 from which it is taken for replay. Alternatively, the cue ball may be too large to enter a pocket. Coin-freed mechanism. The member 12 has a cam portion 13, and is rocked against the action of a spring 17 to allow the object balls to pass under the barrier 10<a> to the trough 11 by pressing in a coin-freed slide 14, a roller 16 on which coacts with cam 13. The appropriate coin is inserted in a slot 19 in slide 14 and rests on a fixed guide 20. Coacting with the slide is a sprung pawl 18 which engages the slot 19, if a coin is not inserted therein, and prevents the slide from being pressed in any further. Normally, however the pawl rides over the coin, and on continued inward movement of the slide the end 21<a> of a spring lever 21 forces the coin through a hole 24 whence it drops into a collecting box 23. Until the coin passes through the hole 24 the end 21b of lever 21 prevents completion of the inward movement of the slide. Should the coin inserted be too small it falls through a hole 15<a> into the box 23 and the pawl 18 engages the slot 19. Each side of the table may carry a scoring device comprising beads slidably mounted on horizontally disposed wires.

Patent GB-192437-A (GB)
Title: Improvements in seal-padlocks
IPC: E05B67/22
Filed: 1922-06-27
Abstract: 192,437. Pasley, W. H. June 27, 1922. No Patent granted (Sealing fee not paid). Padlocks; seal locks.-A padlock is provided with a paper or cardboard seal and mechanism for perforating the seal when the key is turned to unlock the padlock. The casing a contains the seal d and punching plunger m<1> at its upper end and the bolt h<1> which has locking mechanism at its lower end, and is closed by a screwed cap b which is locked against removal by the longer leg c<1> of the shackle c when the padlock is locked. The bolt h' slides laterally in the disc h and carries at its engaging end a crosspin h<2> which is blocked by a tongue i' on the pivoted spring retained rocking piece i' of the disc i and the spring j<2> on the underside of the disc j. When the key is inserted into the keyhole b<1> its end engages the cross slot j' in the disc j. The first half turn of the key rocks the piece i<1> of the disc i and turns the disc j, so removing the blocking means i<4> and j<2> from the path of the bolt. The turning of the disc j also brings the perpendicular end of one of the inclined slots j<5>, j<6> on its upper face into engagement with the end of the blade spring l<1> fixed in the bottom of the rotating disc l. On further turning the key to complete the rotation, the bolt h' is withdrawn from its notch c<6> in the shackle leg c<1> and the disc l is turned. Inclines l<2> on the disc l co-operate with corresponding inclines on the base m<2> of the plunger m<1> which is forced upwards by the turning of the disc l to perforate the seal d. The turning of the key to effect this operation and to withdraw the bolt brings the blocking means i<4> and j<2> in front of the pin h<2> on the bolt and prevents re-locking until the key is turned in the reverse direction. To place the seal in position, the shackle is withdrawn until the leg c<2> is clear of the cover plate e which can be moved aside about the leg c' und the seal inserted between it and the top of the casing. The reverse turn of the key to lock the shackle after the legs have been thrust home in the casing does not cause the plunger m<1> to rise and damage the seal since the spring l<1> rides up the incline j<5> or j<6> in the direction opposite to that required for engaging the perpendicular ends of the inclines. A guide f with slots f<1> engaging pins g prevents the plunger m<1> from rotating and a sping x tends to keep the plunger in its inoperative position. The discs h, i are held against rotation by a feather engaging featherways in their peripheries and in the casing.

Abstract: 1311155 Feeding strip material MEKTRON NV 27 May 1970 [28 May 1969] 25554/70 Heading B3W Strip material is fed to successive stations of a punch press by a feed device comprising a plurality of grippers spaced along advancing means for moving each gripper between a working and an idling position. Each gripper includes a movable jaw, means for moving the jaw to grip and release the strip when the gripper is in its working and idling positions respectively and a guide jaw for slidably engaging a guide rod, which extends in the feed direction, when the gripper is in its working position. As shown, strip 66 is fed by grippers 64 distributed uniformly about a chain 62 driven by rotation of a shaft 54 on which a sprocket 58 is mounted. Each gripper comprises a fixed jaw 88 and a movable jaw 96 and engagement of a cam follower roller 150 on the gripper with a stationary cam 152 causes the jaw 96 to grip the strip when the gripper moves into a working position in which it is guided on a fixed rod 68. The roller 150 is mounted on a block 120, which is vertically slidable in gripper housing 74, and pivots arms 106 to reciprocate the jaw 96  vertically through a pin 112 passing through the block 120 and slidable in slots 122 in a fixed portion 80 of the housing 74. The pin 112 is moved from one end of slots 112 to the other with a toggle action by means of springs 118 mounted on rods 114 connected to pins 116 rotatable in the portion 80. As a gripper 64 reaches the working position the guide rod 68 is located in a recess 76 in the gripper housing 74 and bronze jaws 130 forming part of arms 124, 126, pivoted at 128, embrace the rod to retain the gripper thereon. The jaws 130 are moved to embrace the rod when rollers 140, 142 at the ends of the arms remote from the rod engage a cam bar 138. Preferably four grippers are in working position at a time, a cam 156 being provided to disengage the gripper jaws 96 from the strip 66. The rollers 140, 142 run off the cam bar and a spring 160 urges the arms 124, 126 apart to an extent determined by an adjustable stop 162. When a gripper is in idling position the arms 124 ride on a track 70, Fig. 3. The strip is urged against a gripper surface 92 by rollers 146 on a plate 148. To accommodate strip of different widths the table 36 on which the chain and gripper assembly is mounted is connected to shafts 20, 22 slidable relative to the machine bed 10 by screw means 164 &c. (Figs. 2 and 5, not shown) lockable by means of a handle (180). The toggle action linkage 112, 114 &c. may be replaced by an air operated valve arrangement, Fig. 6 (not shown). The shaft 54 may be driven continuously or intermittently in accordance with a numerical punched tape programme which may also control the operation of a multistation punch press to which the strip is fed (Fig. 7) by causing gags (222) to be moved by air cylinders (226) selectively to bring diesets (210), (212) &c. into operation.

Abstract: 380,929. Shearing. MÍLLER, F., 10, Karl-Lehrstrasse, Duisburg, Germany. Sept. 11, 1931, No. 25560. [Class 83 (iv).] Power hammers.-Bars are cut while moving over a rotatable anvil by a knife on a falling plunger. A knife 5, Fig. 1, is pivoted at 6 to a plunger 1 operated by a spring 3 or by gravity, and is normally held by gravity in the position shown but may rock to permit it to move with the work, which is fed over a rotating anvil 7 on a shaft 8, when the cut is made. The plunger 1 is retained in the inoperative position by a pawl 10, Fig. 3, engaging a recess 11 therein, but is allowed to fall under the action of the spring 3 when the pawl is released by a handle 12. A gear segment 14 is simultaneously actuated to rock a segment 15 and a lever 17, the latter permitting a pawl 20 to drop into a notch 24 of a disc 25. A lever 21 carrying the pawl 20 receives motion from the shaft 8 through a gear 32, crank 33, and links 23, 22, and rotates the disc 25 through 90‹. A cam 29 is thereby rotated through gearing through one revolution and bears against a roller 30 to raise the plunger to its upper position where the pawl 10 again enters the notch 11, and retains the knife in inoperative position until the handle 12 is actuated for the next cut.
