Abstract: 1,117,762. Removing bark. H. T. JUHOLA. 27 April, 1965, No. 17769/65. Heading B5L. A machine for removing bark from logs comprises a rotatable cutting device 11, a transporting device 8 located adjacent the cutting device for moving a log towards the cutting device, and a feeding device 10 which is disposed above the transporting device and, in operation, is brought into contact with the log, the feeding device consisting of a steering knife having an edge which is arranged to push the log against, and to be movable in various directions relative to, the cutting device and the transporting device. The cutting device consists of a disc which has three blades 21, Fig. 2, and is mounted on a shaft 20 connected by a belt drive 9 to a shaft 18 adapted to be driven by the power shaft 32 of a tractor, the latter having lift arms connectible by pegs 38 to the frame 19 of the machine. The transporting device is coaxial with the cutting device and consists of a conical helically-threaded member 8 which when rotated carries a log supported thereby towards the cutting device, the log being fed to the machine from a support 40 adjustably mounted on the frame 19 and passing from the machine over a roller 41 also adjustably mounted on the frame. The steering knife 10 of the feeding device is carried by a rod 22 rotatably mounted in a member 1 which is connected by pivots 25, 26 to the ends of links 2, 15, the other ends of which are connected by pivots 27, 28 to a main beam 4 on the frame 19. A shaft 3 of adjustable length is also pivotally mounted at one end on the beam 4 and at its other end is connected by a linkage 5 to a sleeve 23 adjustably secured to a hand lever 13 secured to the steering knife 10 whereby the edge of the knife can be adjusted relative to the axis of the transporting device and cutting device to vary the rate of feed of a log. A toothed member 14 is mounted on a pivot 34 on the member 1 and is urged by a spring 35 towards the cutting device but is prevented from engaging the device by a stop 32. A further stop 31 prevents a spring 29 acting on the link 2 from engaging the toothed member 14 with the transporting device. In operation, a log from the support 40 is placed with one end on the transporting device 8 which moves the log towards the toothed member 14 and the cutting device. The rotation imparted to the log by the transporting device 8 lifts the toothed member 14 together with the member 1, knife 10 and a plate 12 attached to the member until the knife and plate are above the log, the toothed member then moving to the other side of the log to act, with the device 8, to press the log against the cutting device. The knife edge engages the log to cause it to move axially as it is rotated, the axial feed depending on the adjustment of the knife. The dimensions of the links 2, 15 are such that when the knife is raised by engagement of the log with the toothed member 14, the angle between the knife edge and axis of the device 8 is reduced to automatically reduce the rate of feed of the log.

Patent GB-820260-A (GB)
Title: Process for the production of dl-threo-1-phenyl-2-nitro-propan-1, 3-diol
Filed: 1958-06-05
Abstract: The invention comprises a process for the production of DL threo-1-phenyl-2-nitro-propan-1,3 diol by mixing salts of DL 1-phenyl-2-acinitro-propan, 1-3 diol in an acidic medium with a reagent capable of removing nitrite ions, and separating the threo compound from the resulting mixture of nitropropandiols.  Examples of suitable such reagents are hydroxylamine, urea, hydrazine, semicarbazide or their salts, especially the aqueous solutions of the mineral acid salts of hydroxylamine.  If the reagents are used in their free state acid must be added to the reaction medium to retain the acidity thereof.  The acinitro compound may be prepared by condensing benzaldehyde with b -nitroethanol in methanolic solution with sodium methylate or formaldehyde with phenyl b  nitro ethanol. The threo isomer formed in the process of the invention may be separated and crystallized, e.g. by the use of n-butyl ether, and the remaining erythro compound may be converted into salts of the acinitro compound by the addition of bases, preferably sodium alcoholate.  The salts may then be mixed with the above-mentioned nitrite removing agents.  The DL threo - 1 - phenyl - 2 - nitro - propan - 1.3 - diol obtained may be hydrogenated, e.g. using a palladium animal charcoal catalyst, at atmospheric pressure and room temperature in glacial acetic acid to form the corresponding amino compound.  The erythro compound may be purified by condensing with acetone in the presence of phosphorus pentoxide and hydrolysing the 2.2-dimethyl-5-nitro-6-phenyl-1.3 dioxane, so formed, with 0.5 N hydrochloric acid, when pure DL erythro 1-phenyl 2-nitropropan-1.3 diol is formed, which may then be reduced to the amino compound.

Title: Improvements in or relating to coin-freed gaming apparatus
IPC: G07F17/38
Filed: 1960-05-23
Abstract: 943,545. Tivoli billiards. G. WULFF, [trading as GUNTER WULFF-APPARATEBAU]. May 23, 1960 [May 21, 1959], No. 18095/60. Heading A6H. [Also in Division G4] A coin-freed gaming apparatus comprises a ball game 16 with drop channels 24 having associated symbols, such as 1, 2, 3, 4, and an indicator 3 showing different combinations of three of these symbols in vertical rows 4-10, the first playing period causing the symbols according to the drop channel through which the ball passes to be illuminated in the top horizontal row of the indicator and the second playing period similarly illuminating numbers in the second row, thus allowing the player, in the third and final period, to try for a symbol in the third horizontal row which will give a vertical combination of three symbols offering a higher prize, as indicated by the coin values shown in a fourth horizontal row 12. The ball is shot along a curved track 14 by a trigger 13 and falls through guide pins 17 and pass bouncing pins 18 into the drop channels 24. The pins are flexible and coated with resilient material and pass through enlarged holes in a wall of the apparatus into a rail which may also be made of flexible material. The balls are guided through the channels 24 by tongues 26 on the separating arms 25 and operate an indicator switch 27 in each channel before striking guide springs 29, 30 and passing into a blocking channel 31. In the channel 31, the ball actuates a control switch 32 and falls to a catch pin 35 which is withdrawn periodically and ensures that the game lasts a specified minimum period independently of the time taken by the ball to fall through the apparatus. On release of the ball by the pin 35, it falls to the trigger 13 and a lamp 37 is illuminated to indicate that another playing period can begin. A motor-driven control shaft makes four quarter rotations during the course of the game, the first being started by the coin inserted and stopped by a cam on the control shaft to give the first period of play. Further cams, together with operation of the switch 32 by the ball, start the second and third quarter-rotations and operate a solenoid controlling the catch pin 35 so that the ball is released. One particular cam is associated with each combination 4-10 and has a number of ratchet teeth corresponding to the prize amount of the particular combination. Step switches associated with the individual symbols are also provided with cams and together with the switches 27 in the drop channels, serve for switching on the lamps in the indicator 3 and for establishing a circuit for actuating the pay-out solenoid by way of the " winning " cam on the control shaft, during the last quarter-rotation of the control shaft. The winnings fall to a tray 39 and it is possible to re-illuminate the indicator, up to the start of the next game, by operating a knob 38.
