Filed: 1953-01-29
Abstract: 726,549. Endless conveyers. ESKIMO PIE CORPORATION. Jan. 29, 1953, No. 2641/53. Class 78 (1). [Also in Group XIII] Portions of partially frozen ice cream &c. are fed successively at a charging station 3 to carrier 17 on an endless chain or other flexible member 14x which carries them along an extended path in contact with two sets of inclined refrigerator conduits 6, the carriers moving upwardly in one set and downwardly in the other to a discharge opening 2 in the insulated casing of the apparatus. The casing 1 encloses two sets of refrigerant conduits 6 of square cross-section, each set comprising two stacks as shown in Fig. 7 in inclined superposed lengths to form an extended path for the carriers 17 fixed to the endless chain 14x passing over sprockets 9, 10, 13, 14 on vertical shafts 7, 8, 11, 12 driven by a motor 17x. The chain 14x passes from the lowermost right-hand sprocket 10 to the lowermost left-hand sprocket 9 which is slightly higher than the sprocket 10 and thence back and forth between the sets of sprockets 9, 10 until it reaches the top, where it passes to the other stack of conduits and is led to and fro downwardly between the sets of sprockets 13, 14 along the conduits and at the bottom returns to the bottom of the first stack. At the level of the loading opening 3 the leaders 30 are offset at 30x to allow the chain 14x to extend at this point to a sprocket 9x outside the casing whereby the carriers 17 project through the opening 3 and are loaded with portions of partially frozen ice cream from a continuous freezer, the mix being cut off by a cutter. The carriers then pass into the casing and upwardly to the top of the stack, downwardly in the other stack and then upwardly in the first stack to the discharge position where the completely frozen ice cream portions are removed from the carriers by a guide 37 and fed on to a belt 36 which deposits them on to a belt 37x leading to a chocolate enrober.

Title: Improvements relating to nuts for receiving screw fastenings
IPC: F16B37/04
Filed: 1951-02-02
Abstract: 687,618. Anchor nuts; locking nuts. ILLINOIS TOOL WORKS. Feb. 2, 1951 [March 9, 1950], No. 2671/51. Class 89 (i) An anchor nut comprises an assembly of a nut and a retainer, inseparable axially but relatively rotatable, so that in one position the nut may be passed through an aperture in a plate &c. and then be turned relatively to the retainer to a position in which the nut spans the aperture on side one and the retainer on the other. A rectangular nut has a flange 26, Fig. 4 that is passed through a slot 28 in a sheet metal retainer and riveted over at 32, the slot permitting rotation and limited float. The retainer. is bowed at 30, flanged at 34 to engage a rectangular hole in a plate &c. 40, the flanges having lugs 36 that bear against the surface of the plate. The nut is passed through the hole in the plate and rotated through ninety degrees, the ribs 42 then bearing on the plate on opposite sides of the slot and the bowed part of the retainer entering the slot and also in between the ribs preventing further relative movement. When the nut is tightened the resilience of the retainer causes it to act as a friction lock washer. The corners of the ribs are bevelled at 52 to facilitate camming down the bowed part of the retainer should it be required to remove the nut. In modifications the flanges 34 of the retainer are replaced, in one form, by slit and bent up fingers and in another by ribs or beads. In other modifications fingers 42c, Fig. 12 are cut from the centre of the flanged part of the retainer and have their ends upturned oppositely to the flanges. In the assembly position these ends bear on the ribs 42 and in the anchored position they engage the ribs of the nut. In a further form a conical flange round the bolt hole of the container is retained in a groove in the nut, dimples 54, Fig. 15, maintain the nut and retainer in the assembly position whilst resilient fingers 42c lock the nut in the anchored position.

Title: A process for improving the stability of polyolefines
IPC: C08F8/34
Filed: 1965-01-25
Abstract: The stability of a polyolefin is improved by dispersing the purified polyolefin powder in an inert hydrocarbon medium, admixing therewith an organic sulphur compound HSR, wherein R is a hydrocarbon or alkyl ester radical, heating either with an organic peroxide or under the action of U.V. light, separating the polyolefin, and then washing with the inert medium.  In examples, heptane, hexane and benzene are used as media and peroxides used are dibenzoyl-, dicumyl- and di-t-butyl peroxides. The stability of the treated polymers is tested in compositions containing dilauryl thiodipropionate and 4,41-thio-bis-(3-Me-6-t-Buphenol).

Class 100 (2) Rotary offset machines; cylinder adjustments. -In an offset printing machine the three printing components, the printing cylinder 14, Fig. 1, the offset cylinder 19 and a shaft 20 for holding a work piece 21, for example, a small wheel to be peripherally printed, are mounted to turn with gear wheels 29, 23, 24 on shafts 25, 22, 20, the gear wheels meshing with idler gear wheels 26, 27, 28 respectively which mesh together during the printing operation to form a gear train driving the three components synchronously. A similar arrangement may be adapted for printing on a tape. A driving wheel 17 on the shaft 18 of an inking roller 13 meshes with the gear wheel 29 of the printing cylinder. The printing cylinder 14 and offset cylinder 19 are mounted on arms 42, 30 having quadrants engaged by worm gears 43, 41 rotatable to adjust the pressure between each cylinder and the next. The work shaft 20 and its associated gear wheel 24 are similarly mounted on arms 39 angularly adjustable by a quadrant and worm gear 45. The arms 39 are pivoted about the axis of the idler gear 28 which is mounted on swinging plates 32 spring loaded to maintain a cam-follower 34 thereon in contact with a cam 36: The plates 32 are swung by rotation of the cam to three positions. In the first or loading position the shaft 20 is aligned with a rod 39 on which are threaded the work pieces 21a which are waiting to be printed on the circumference. One of the work pieces is then passed on to the shaft 20 by hand or automatically and the cam rotated to bring the plates 32 to the printing position in which the idler gears 27, 28 mesh and the work piece engages the offset cylinder. After the printing operation the plates are swung to the third position in which the shaft 20 is aligned with a receiving rod 40 on to which the printed work piece 21b is passed by an ejecting device. The cycle of operations is then repeated with another work piece. In the form of Fig. 4 a machine for printing on a tape 51 comprises an impression cylinder 53, an offset cylinder 50 and a printing cylinder 57. The cylinders 53 and 50 are interconnected by idler gears 59, 154, the latter being driven from a gear box 155. The printing and offset cylinders are connected by idler wheels 54, 55. The printing cylinder is mounted on a head 158 pivoted about the axis of gear wheel 55 so that the printing pressure can be adjusted by a screw 159. The pressure between the cylinder 53 and offset cylinder 50 is adjustable by a screw 64 connected to a lever 62 carrying at the opposite end the cylinder 53. The tape is retained against the cylinder 53 by a jockey wheel 52.
