Title: Irradiation chambers
IPC: G21F5/02
Filed: 1965-08-27
Abstract: 1,055,218. Irradiation apparatus. SULZER BROTHERS Ltd. Aug. 27, 1965 [Sept. 8, 1964], No. 36940/65. Heading H5R. In irradiation apparatus, each radiation source is retractable from an irradiation chamber 1 into a shielding block 4 which forms part of the roof of the chamber. Each source comprises a number of capsules of Co 60, for example, connected in a chain and accommodated in a helical passage in the block 4. The chain has a cable attached to the higher end, running in a narrower passage 10 and winding round a drum 11 accommodated in a housing 14 in the block. The drum can be rotated, through gearing, by a hand wheel 17 to let out the cable and lower the source chain out of the block into a guide tube 20 in the irradiation chamber. The guide tube is S-shaped and can rotate about the end leading from the block, so that the source can be brought near the material to be irradiated. In one arrangement (Fig. 1), the bottom end of each tube 20 is supported by a pivoted arm 21. In another (Fig. 2, not shown) each guide tube is attached only at its upper end and it does not obstruct the floor of the chamber. It is also easily removable, which is advantageous when a large number of source chains and corresponding guide tubes are used, these being arranged in circular formation around the material 23. The pitch of the helix of a tube 5 is so arranged that if a supporting cable breaks. the friction of a source chain against the inside of a tube 5 will prevents its slipping downwards into the chamber. Each cable is led on to the drum through a pivoted tube 13, although in another arrangement (Fig. 3, not shown) the drum is specially mounted so that the level at which the cable enters a groove remains constant, and the pivoted tubes may be dispensed with, the tubes 10 communicating directly with the drum. Two types of joint for the chains of source capsules are described (Fig. 1 and Fig. 4, not shown). The drum 11 may be located outside the shielding block and may be provided with a helical toothing for use with a special type of support cable. Remote control means may be provided, utilizing limit switches. Warning and locking devices may also be provided.

Title: Antibiotically active derivatives of spiramycins
IPC: C07G11/00
Filed: 1956-12-11
Abstract: Neospiramycins having in general greater antibacterial properties than the spiramycins are prepared by adjusting aqueous, alcoholic or aqueous alcoholic solutions of the corresponding spiramycins (spiramycin, spiramycins I, II and III or their mixtures) to a pH of 3 to 5 with an acid such as sulphuric acid and maintaining said solutions at a temperature between 20 DEG  and 50 DEG  C. until their antibacterial activity remains constant when tested against B. subtilis ATCC 6633.  The reaction solution is made alkaline, e.g. to pH 10, with sodium hydroxide, extracted with a water-immiscible solvent and the neospiramycin isolated by evaporating the solvent at below 50 DEG  C.  It is further purified by recrystallization. Suitable water-immiscible solvents are aromatic hydrocarbons such as benzene, chlorinated hydrocarbons, e.g. chloroform or dichloroethane, ketones, e.g. methylisobutyl ketone, esters, e.g. ethyl or amyl acetate, and ethers, e.g. diisopropyl or diethyl ether.  An inactive substance containing 51.8 per <FORM:0801536/IV (b)/1> <FORM:0801536/IV (b)/2> <FORM:0801536/IV (b)/3> cent carbon, 8.90 per cent hydrogen and 39.35 per oxygen remains after the removal of the neospiramycin.  Neospiramycins I, II and III may be prepared directly from the correspinding spiramycins, or from (a) spiramycin complex, and (b) a mixture of spiramycins. In the case of (a) and (b) individual neospiramycins are obtained from the mixtures of neospiramycins by countercurrent distribution or chromatography on alumina.  The properties of the neospiramycins are as follows: <TABS:0801536/IV (b)/1> <TABS:0801536/IV (b)/2>

Title: Tractor hydraulic system
Inventor: PRICE WILLIAM RICHARDS
IPC: A01B63/112
Filed: 1960-11-04
Abstract: 922,428. Fluid-pressure servomotor control systems. FORD MOTOR CO. Ltd. Sept. 22, 1961 [Nov. 4, 1960], No. 38002/60. Class 135. [Also in Group XXXI] The pump 1, a tractor power-lift supplies fluid through a dump valve 4 to a pipe 11, the valve comprising a spring-loaded plunger 5 slidable in a bore 6, the amount of fluid dumped thereby being conditioned by the area of an adjustable restriction 9 so that the flow into pipe 11 is a fixed quantity. Pipe 11 leads by annulus 12 and passages 13, 14 to a valve 15, which in the position shown, connects passage 14 to a reservoir 2 via an annulus 16, port 34 and passages 17, 18 and 19. A lever 21 is moved to the position shown to lift the plough to the transport position, this lever movement rotating clockwise a crank 22 and swinging a lever 23 about a pivot 43 so urging a control valve 25 leftwards; the resulting uncovering of a port 27 enables fluid from annulus 12, to flow through a port 29, an annulus 30, and a passage 31 to shift the valve 15 to the right and close port 34 whereupon the fluid pressure rises in passage 13 and lifts a check valve 35 so that fluid is suppli d to the ram cylinders 36 by a passage 67. When the ram piston 37 abuts a pin 68 it moves the lever 23 and valve 25 to the right until port 27 is uncovered so enabling fluid " blocked in " against the piston area 32 of valve 15 to be directed to the reservoir; the back pressure on the other piston area 33 of valve 15 then moves the latter to the left and uncovers port 34 whereby the pipe 11 is again open to the reservoir. On draught control the ploughing depth is set by the position of lever 21 which adjusts the gap between the abutment 41 and the pivot 43; if the draught resistance increases beyond this datum a reaction spring 42 is compressed and a plunger 44 and a rod 45 move to the left, and if the gap is closed the lever 23 is translated to actuate the valve 25 and lift the plough. The adjusting member 50 of the restriction 9 is coupled by linkage to the lever 21 in such a way that when the latter is moved to the lift position the effect of the dump valve is neutralized and when the lever 21 is moved down the quadrant for deep ploughing the dump valve is set to deliver the amount of fluid required to match the operation being performed. To operate external hydraulic equipment the passage 67 embodies an isolation valve 66 with a tapping 65; the valve 66 may be operated when the lever 21 is moved up to a stop defining the neutral position of the apparatus; to lift the plough in these circumstances the lever is moved beyond the stop and means are provided to compensate for this extra movement in relation to the operation of the dump valve.
