Title: Improvements in or relating to power steering systems
IPC: F16H25/22
Filed: 1956-05-25
Abstract: 809,301. Vehicle power steering. THOMPSON PRODUCTS Inc. May 25, 1956 [June 3, 1955], No. 16305/56. Class 79(5) In a power steering system having a recirculating ball nut 15 mounted on a manually rotatable steering shaft 10 so as to be capable of axial and limited rotary motion on rotation of the shaft 10 a hydraulic steering motor control valve 26 has its spool 32 movable on rotary movement of the nut from a normal position against the action of a spring 50 along an axis transverse to the steering shaft axis, and across shaft 18 extends in substantially the same direction as the valve spool 32 and is arranged to be rotated by the motor (not shown) to counteract the rotary movement of the nut 15 whereby the valve is only operated as long as the rotaton of the shaft 10 continues against a steering load. As shown in Fig. 1 the invention is applied to a steering gear comprising the recirculating ball nut 15 on the shaft 10 having teeth meshing with teeth 17 on the shaft 18 carrying an arm 19 connected to the steering linkage (not shown). The nut 15 slides within a U- shaped axially fixed lever 27 having a ball and socket connection 28 to a reciprocal link 30, which is connected by a universal ball joint to the valve spool 32 co-operating with a ported valve body, The valve body has a pressure inlet 43, power cylinder conduits 44, 45 and an exhaust conduit 46, which leads into the gearing housing 23 to lubricate the gearing. In the event of hydraulic failure manual steering is maintained by abutment of either portion 34 or 35 of the lever 27 with the housing 23. In a modification Fig. 3, the teeth on the nut 15a meshes with teeth 35a on a sleeve 17a having a threaded connection 63 with the shaft 18a, the teeth on nut 15a and sleeve 17a being conventional spur gear teeth cut in a plane lying at an angle to the axis of rotation of the shaft 18a whereby meshing of the teeth can be adjusted by shims 61a bearing against a strong Belleville spring 62a. The shaft 18a is mounted in the housing 23a for limited axial movement on rotation of the steering shaft 10 due to the connection 63, such movement actuating the valve spool 32a and being limited by stop elements 65, 66 and the valve spool being connected to the shaft 18a by a bolt and nut 68.

Title: The antibiotic, takamycin, and process for the production of the same
IPC: C12P1/06
Filed: 1962-04-30
Abstract: <PICT:1006547/C2/1> The antibiotic Takamycin is obtained by cultivating Streptomyces takataensis or an antibiotic Takanycin - producing mutant thereof in a culture medium containing as essential constituents carbon and nitrogen sources under aerobic conditions and recovering the antibiotic from the mycelium and the culture broth. Preferably the culture medium is liquid, contains inorganic salts and is cultivated at pH 7.0 and 27-30 DEG  C. for 3 to 6 days under submerged aerobic conditions.  Takamycin is recovered from the mycelium by extraction with methanol, ethanol or acetone, followed by washing with ether or ethyl acetate and recrystallization from aqueous ethanol; and from the culture filtrate by adsorbtion on Japanese acid clay, elution with butanol/pyridine/water, concentrating the eluate, and washing and recrystallizing as above. Takamycin is a yellow crystalline amphoteric substance decomposing at 150 DEG  C., soluble in pyridine, dimethylformamide and glacial acetic acid, hardly soluble in diethyl ether; chloroform, petroleum ether and moderately soluble in methanol, ethanol and acetone, particularly at an alkaline pH and insoluble in water at acid and neutral pH; having u.v. maxima at 341, 360, 380 and 405 mm  (Img/ 100 ml. of methanol); an I.R. spectrum as shown in Fig. 2; gives negative ninhydrin and o-nitrobenzaldehyde reactions and shows the elemental analysis c = 60.48-59.51%, H = 7.93-7.70% and N = 3.05-2.64%.

Title: A process for the polymerization of conjugated dienes
IPC: C08F10/00
Filed: 1963-04-29
Abstract: One or more conjugated dienes, of which at least 5% by weight is butadiene, are polymerized in contact with from 0.05 to 2% by weight of the diene(s) of a catalyst consisting of cobaltous fluoride and either an alkali metal fluoride or zinc fluoride in a mol. ratio between 1 : 05 and 1 : 2, the polymerization being conducted in an essentially oxygen-free, aqueous medium (i.e. an aqueous medium containing less than about 1,000 parts per million of dissolved oxygen) in the presence of an alkali metal alkaryl sulphonate emulsifier and in the absence of free radical supplying catalysts. The pH of the aqueous medium is preferably between 6.5 and 7.7.  The catalyst components may be added separately to the aqueous phase or may be mixed prior to use; also, the catalyst may be added before or during the polymerization, or at specified intervals during polymerization. When butadiene, alone, is polymerized, the polymer obtained with a CoF2/NaF catalyst generally has a high cis 1,4-content; with a CoF2/KF or CoF2/LiF catalyst, the polymer is mainly the trans 1,4 product.  Other dienes which may additionally be used in the polymerization include isoprene and chloroprene. Examples illustrate the preparation of polybutadiene and include experiments wherein comparison fluoride catalyst components and comparison emulsifiers are used.

Heading H1T. A voltage difference obtained across tappers of a secondary winding of a transformer is varied by arranging that the contact points on the tappers which are simultaneously movable, sweep in opposite directions along a slide path of the secondary. In one embodiment (Fig. 7) the contact points 71 of tappers 56, 57 sweep in opposite directions over the secondary along path 58 as cam plates 60, 63 having grooves 65, 66 which co-operate with stops 67, 68 on the tappers are rotated. In a second embodiment an asymmetrical cam (Fig. 6, not shown) whose periphery bears on the tappers is rotated to move the tappers apart. In another embodiment; the tappers may be so arced (Figs. 1 and 2, not shown) that as they are simultaneously rotated in the same direction their points of contact with a projecting straight track on the secondary either approach or move apart. In a further embodiment, tappers are mounted on a continuous cable which passes round a control pulley, the rotation of which adjusts the separation distance of the tappers (Fig. 5, not shown). The central portion of the secondary winding may be of so reduced diameter that it can never be contacted by the contact points of the tappers (Fig. 8, not shown). The positioning of the tappers is controlled by a rotatable knob which is so connected to a polarity reverse that the direction of rotation of the knob determines the polarity of the tapped voltage.
