Title: Improvements in holders or supports for rolls of toilet paper and the like
IPC: A47K10/40
Filed: 1920-07-13
Abstract: 169,325. Anderson, W. H. July 13, 1920. Bobbin holders.-A holder for rolls of toilet paper &c. is constructed in such a manner that the roll cannot be removed when once in position until all or nearly all the paper has been used. The roll is held by rollers 13 on arms 6 pivoted to a foundation plate 1 by pivots 4, 5, of which the latter has a conical end 8 slotted longitudinally at 11 so that when the roll is so reduced in diameter that the arms 6 are nearly vertical the pivot pin 5 can be slid outwards, a spring pin 10 in this position registering with the slot 11. In all other positions, however, the pin 10 and slot 11 do not register, so that the pivot pin 5 cannot be withdrawn.

Patent GB-571518-A (GB)
Title: Improvements in or relating to a process for spinning protein
IPC: D01F4/00
Filed: 1943-12-22
Abstract: Small amounts of acridine dyestuffs are added to concentrated protein spinning solutions, particularly those to be used in dry spinning processes.  The acridine dyestuffs prevent putrefaction of the protein solutions and formation of gas bubbles therein during storage or treatment for spinning.  The spinning operation is facilitated since stronger threads are produced and there are less breakages.  In examples, spinning solutions comprise 24-26 per cent of casein, 0.5 per cent of oleic acid, and 0.005-0.01 per cent of an acridine dyestuff, dispersed in caustic soda solution of sufficient concentration to give a solution with a pH value of 9.2.  The solutions may be used for spinning artificial threads at 40 DEG  C. even three or four days after the original preparation.  Dyestuffs specified are: 2-ethoxy-6, 9-diamino-acridinium lactate, 10 - methyl - 3 - amino - 9 - (4 - amino - phenyl) - acridinium hydrochloride, 10 - methyl - 3, 6 - diamino - acridinium hydrochloride and 2,8-diamino-acridinium hydrochloride.

Title: Improvements relating to the purification of benzene
Inventor: BRADLEY DEREK
IPC: C07C7/14
Filed: 1960-06-22
Abstract: Benzene is obtained in purified form by crystallising in a first stage and separating the crystals from the mother liquor and treating the mother liquor in a second stage according to the process of the parent Specification by crystallising, separating the crystals, partly thawing the latter by contact with an aqueous liquid and returning the thawed benzene to the second crystallisation, the two sets of crystals being combined. Preferably the first crystallisation is effected to obtain a product of the desired purity and the second stage effected to obtain crystals, after the washing step, of the same purity, i.e. of similar melting point.  The mother liquor from the second stage may be distilled to recover further amounts of benzene which is recycled to the second stage.  Both crystallisations may be effected by turbulent mixing with brine and separation and washing steps are effected in a centrifuge.

[Class 83 (iii).] A machine for making bobbins from boards of thickness corresponding to the bobbin diameter has means for automatically forming, drilling and severing the bobbins and feeding the board so that it is progressively used up. A sweep cutter 27 with an adjustable boring bit 35, Fig. 3, constitutes the means for cutting the bobbins from the end of a board, and is reciprocated axially by a bent lever 30, rod 28 and pin 26 engaging a cam groove in a rotating disc 25, the cutter is rotated by belt means from a pulley 38 carried at the end of the main driving shaft underneath the machine ; a worm drive from this shaft rotates the cam disc 25 through the vertical shaft 8 when a clutch element 49 is in its upper position, Fig. 2. The board (not shown) is carried by rollers 15, 16, 18, the latter being vertically adjustable by a screw 23, which are mounted on a table 11 adapted to slide on guides 12. Subsequent to the bobbin forming and drilling operation a circular saw 44, mounted at the end of a rocker arm 45, Fig. 5, and driven by belt means from the main drive, is fed downwards to sever the bobbin by link gear 46,.47 and pin 48 also engaging the cam disc 25 but lagging the cutter controlling pin 26. The board is next fed sideways a distance equal to the bobbin pitch by a striker rotating at the top of the vertical shaft 8 engaging a rack 14 fixed to the table 11. When a complete transverse strip of the board has been used in the above manner the table is returned to the initial position by a stop 59 moving the lever 54 over to connect the clutch on the vertical shaft 8 so that the drum 50 winds the cable 58 and moves the table until another stop 60 disconnects the drive ; at the same time the serrated roller 16 is rotated a fixed amount through a ratchet device 63 controlled by a cable and weights and serves to move the board a longitudinal distance equal to the length of the bobbins, the cycle of operations is then repeated.
