Title: Improvements in motor-vehicle steering gear
IPC: B62D5/24
Filed: 1956-07-30
Abstract: 841,567. Vehicle power steering. MASSEY-FERGUSON Inc. July 30, 1956 [Aug. 19, 1955], No. 23393/56. Class 79(5). In a motor vehicle steering gear a spindle 38 is connected to a manually operated steering shaft 58 by worm gearing 54, 56 and carries vanes 66, 68 of a hydraulic motor, the chambers of which are pressurised and exhausted, and hence the spindle is rotated by power assistance, under the control of a valve 94 having a spool 106 axially moved with the shaft 58 by reaction between the worm gearing 54, 56. As shown the invention is applied to a tractor, the frame 16 of which has an aperture 17 containing the steering gear housing 18 bolted at 20 to the frame. The housing 18 is formed by members 27, 25, 24, 23 bolted together at 29 and the vertical spindle 38 is supported in the housing by needle bearings 34, 36 and a thrust bearing 42. At its lower end the spindle 38 carries a plate 150 for bolting to a single wheel mounting, Figs. 1, 12 and 13 (not shown), or to an arm connected by track rods to two wheels, Figs. 9, 10 and 11 (not shown). The upper end of the spindle 38 carries the wormwheel 54 meshing with the worm 56 on the shaft 58. Secured to the spindle 38 intermediate the housing members 23, 25 is a collar 64 carrying the vanes 66, 68 which cooperate with fixed vanes 80, 82 whereby alternate liquid pressurising or exhausting of chambers 90, 91 causes the hydraulic power rotation of the spindle 38 for steering purposes. The power steering control valve 94 is connected by pipes 134, 135 to the chambers 90, 91 and by pipes 122, 138 to an engine driven pump (not shown). The valve comprises a body 96 and a spool 104 formed on the end of the shaft 58. Axial movement of the spool 104 relative to the body 96 is limited by end faces of recesses 116, 118 formed in the body 96, the spool being centred by spring loaded pins 127, 128 in five bores 125 formed in the body 96.

Title: Mechanism for controlling reciprocation of two rods connected by gearing
IPC: G21C7/18
Filed: 1966-05-25
Abstract: 1,131,652. Controlling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 25 May, 1966 [28 May, 1965], No. 23473/66. Heading G6C. [Also in Division E2] Mechanism for locking in a predetermined end position one rod 5 of a pair of rods, e.g. a nuclear reactor control rod 4 and a counterweight rod 5, geared together by driving gear means for effecting movement in opposite directions comprises slides 10, 11 mechanically coupled for movement in opposite directions perpendicular to the longitudinal direction of the two rods, the rod 5 to be locked having a locking pin 9 whereas the other rod 4 has a control element consisting of two pins 7, 8 so located that withdrawal and consequential displacement of the rod 4 from the gear means causes a displacement of the slides 10, 11 such that slide 11 engages the locking pin 9 of the rod 5 and moves it into and retains it in a locking position in which the gear means is disengaged from the rod 5. In the embodiment shown, the gear means consists of a pinion 6 engaging rack teeth on the rods 4, 5. The slides 10, 11 are coupled by means of a rotatable disc 13 provided with diametrically opposed pins 14, 15 which engage grooves 16, 17 in the slides. The counterweight rod 4 is heavier than the control rod 5 so that when released, the rod 5 is inserted into the reactor core from below, due to the rod 4 descending under its superior weight. The purpose of the locking mechanism is to lock the control rod 5 in its fully inserted position so that the counterweight rod 4 may be removed if this should be necessary. Whilst the two rods are in a normal operating position the two slides assume a position in which they do not interfere with the move - ments of the rods. When it is desired to remove the rod 4, this is pulled down beyond its normal end position which results in the lower pin 8 of the two pins 7, 8 engaging the obliquely cut corner of the lower slide 11 which is thereby displaced sideways until it rides under the locking pin 9. The other end of the slide 11 has two obliquely cut corners of 45 degrees slope, the upper being relieved at an angle of 10 degrees so as to push the locking pin 9 slightly upwards. The control rod 5 is thus lifted and its rack teeth disengaged from the pinion 6. At the same time, it is held in its raised position by the slide 11 carrying the pin 9 and the rod 4 can be pulled down further and extracted. When the rod 4 is reinstalled, the pin 7 displaces the slide 10 to one side, the disc 13 simultaneously moving the other slide 11 to the opposite side with consequential release of the locking pin 9. The rack of the control rod 5 thus re-meshes with the pinion 6 and normal operation can be resumed.

Emulsions. making; insecticides.-Emulsions of heavy hydrocarbons,such as wood or coal tars or mineral oil distillation residues, are prepared with the aid, as emulsifying agents, of concentrated solutions of soluble lignone derivatives from the sulphurous acid treatment of wood or of condensation or oxidation products of such derivatives. Similar products of lignone derivatives from the bisulphite process may also be used. The condensation products may be prepared bv evaporating the lignone derivatives with hydrochloric acid or ferric chloride and subsequently redissolving : such products may be made to dissolve mineral oxides e.g. hydrated ferric oxide. The oxidation products are prepared with the aid of an aqueous solution of chromic acid. The heavy hydrocarbons may be dissolved, e.g. in a solvent hydrocarbon before emulsification. The emulsions obtained are employed e.g. as insecticides, paints or, when mixed with finely divided carbon, as printers' inks. Substances such as bitumen, cotton-seed pitch, linseed oil, tung oil, tallow or dyestuffs, or inorganic salts may be added to the prepared emulsions. The Provisional Specification also describes the use, without further treatment, of lignone derivatives from the bisulphite process as emulsifying agents.
