Abstract: 882,975. Tanning leather. MILES LABORATORIES Inc. Sept. 13, 1960 [Sept. 16, 1959], No. 31555/60. Class 76. Heavy hides are tanned by subjecting the delimed hides to the action of an aqueous dialdehyde starch solution at a pH of 7.5 to 8.5 until the dialdehyde starch has reacted with the innermost regions of the hide to pretan the hide, washing the pretanned hide with water and impregnating the washed, pretanned hide with a solution containing 10 to 15% (weight/volume) of vegetable tannins at a pH of from 3 to 5 until the hide is fully tanned. In examples, sides of cowhide were unhaired with a lime-sulphide solution and then soaked in a deliming bath consisting of ammonium chloride and commercial bate or sodium chloride and sodium acetate. The sides were then suspended in 5-15% of dialdehyde starch, and sodium bicarbonate and sodium sulphate added and the hides allowed to stand for 48 hours. After washing, the hides were immersed in a vat of 14% tannin made up from equal quantities of quebracho and chestnut extract for 5 days and then washed, oiled, and converted to sole leather.

Abstract: 266,843. Davies, W. E., and Godber, B. Dec. 16, 1925. Scoring and marking apparatus; time checks.- Relates to coin-freed markers for games of the kind in which the insertion of coins depresses counter-balanced arms to set free a clock mechanism for a predetermined time and releases operating knobs for scoring dials, an electric light being switched on for the period the clock mechanism is working. According to the invention spring-mounted rollers 12, Fig. 1, are held in engagement with toothed wheels 13 on the spindles of the operating knobs by cams 14 which are moved to release the spindles by the depression after prepayment of two pivoted arms 8, 9. The arms, which have pin-and-slot connections with actuating rods 15 for the cams 14, are pivotally connected and are normally raised by a counter-balance weight 10 on the arm 9. The operating knobs through chain and sprocket gearing rotate indicating pointers over dials. The arms are depressed by the weight of a coin or coins inserted, through a slot 5 and shoot 6 into a bucket 7 on the arm 8, the coins being retained in the bucket until the end of a predetermined time when they are discharged through a shoot 30 to a money-box 31. The arm 9 through a rod 25 removes a spring brake from the balance wheel 21<a> of a clock mechanism 21, and through a rod 24 disengages a pawl 23, Fig. 2, from a slotted disc 22 driven by the clock mechanism. The arm 9 also has a rod 36 which closes an electric light switch 32, 35. The clock mechanism is provided with an outside dial which is 'locked by a bolt 41, Fig. 2, connected by a rod 38 to a lever 37 mounted above. the money-box 31. When the money-box is locked, the lock raises one end of the lever 37 to shoot the bolt 41. In a modification the arms 8, 9 are replaced by a single arm and the arrangement of the other parts are slightly modified. The coins are retained in the bucket 7 by. the portion 29b of a lever 29 held in position by a catch 27. At the end of the predetermined time, a pin 22<a> on the clock disc 22 trips a lever 26 connected to the catch 27 by a a chain 28, thereby releasing the lever 29 which tilts under the weight of the coins. When the arm 8 is depressed the coin-slit is closed by a pivoted plate 11 connected by a rod to the arm.
