Title: An improved steering mechanism for light motor vehicles
IPC: B62D3/02
Filed: 1924-09-16
Abstract: 222,468. Lafitte, T. Sept. 27, 1923, [Convention date]. Steering-gear. - Comprises steering-gear in which the operating and operated shafts which are eccentric to each other, are connected by a speed-reducing device of the kind in which a point on the circumference of a circle on one shaft is guided along a diameter of a circle of twice the size on the other shaft. The steering shaft 2 carries a disc 12 half the diameter of an abutting disc 17 fixed on the operated shaft 18 which is mounted so that its centre passes through the pitch circle of three pins 14 fixed to the disc 12. The pins engage corresponding diametral grooves 16 formed in the disc 17, and the. result is that the disc 12 rotates the disc 17 at half its own speed. In order to allow for wear the pins are tapered and the grooves are correspondingly shaped, the pins and grooves being pressed together by a spring 21. An arm 4 on the shaft 18 is connected to one of the steering arms on the road wheels. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also universal joints between the steering link-work members formed by screwed connections; thus a rod 5 is connected to the arm 4 by a member 23 which is rotatably screwed on the arm and on to which the rod 5 is screwed at 24. The other end of the rod is screwed into a member 25, Fig. 12 (Cancelled), into which is screwed another member 26 which itself is screwed on the steering arm 6. Similar connections are formed on the coupling rod 8. This subject-matter does not appear in the Specification as accepted.

Title: Method of granulating calcium cyanamide
IPC: C05C7/02
Filed: 1921-08-22
Abstract: Calcium cyanamide is granulated by continuously mixing the powdered material with dilute nitric acid, and then granulating and drying in one or several rotating cylinders.  The treatment with the acid is effected in a cylinder having inclined stirring arms which strongly stir and slowly convey the material to the outlet end.  The acid may be admitted by spraying nozzles.  The mixture is dried in heated rotating cylinders which may be jacketed or may have hot gases passed through in counter-current or both means of heating may be employed simultaneously, or the cylinders may be heated electrically.  The granules are separated from dust and large pieces which are mixed with a fresh charge.  The Specification as open to inspection under Sect. 91 (3) (a) states that the cyanamide may be treated with water, which may contain an acid such as nitric acid or a salt such as sodium bisulphate or chloride and that the granules may be treated with a fatty substance such as oil or vaseline, while being dried or afterwards, the fatty substance being supplied in the liquid state.

Title: Improvements in or relating to lubricators for valves
Inventor: HORE DONALD LIONEL
IPC: G05G15/08
Filed: 1959-07-02
Abstract: 926,579. Lubricating valves. ROTORK ENGINEERING CO. Ltd. June 30, 1960 [July 2, 1959; Sept. 24, 1959], Nos. 22799/59 and 32528/59. Class 12 (3). [Also in Group XXIX] A valve lubricator comprises means for supplying lubricant to the relatively movable parts of the valve, said means being actuated by a device responsive to resistance to movements of the parts. A valve spindle 17, Fig. 1, is driven from a reversible motor 10 by a worm and wheel 16, 15, and a spring-urged lever 20 pivotable on the worm shaft 12, actuates torque limit switches 25 to de-energize the motor after the valve is tightened. If the valve sticks prior to the switches 25 being actuated, a piston 27 connected to the bifurcated end 26 of the lever 20 is moved in a cylinder 29 to supply oil from a reservoir 30, through non-return valves 32 and adjustable valves 36, into conduits 40, and thence to the parts of the valve to be lubricated via a conduit 35, thus freeing the valve. In a modification, Fig. 2, the worm shaft 12 is located in a housing 42, and oil is supplied from a reservoir 50 to the bore 44 of the housing. The valve spindle 17 rotates until the valve sticks, whereupon the shaft 12 moves axially to force oil through a conduit 52 to the moving parts to be lubricated. If the lubricant is not sufficient to release the valve, the thrust on the shaft 12 is transmitted to a spring-urged plunger 45 which actuates a motor switch 47. In a further modification, Fig. 4, a motor 71 drives a pump 72 which supplies oil to the valve parts via a slide valve 75. The circuit is normally closed by a portion 82 on the worm shaft 74, but when the shaft moves axially due to sticking of the valve to be lubricated, a reduced portion 80, or 81, opens the circuit. Further movement of the shaft trips a motor switch 79. A manuallyoperated lubricator for use on small bore valves, Figs. 5, 6, comprises a handle 87 rotatable on a lever 88 keyed to the valve spindle 89. An oil reservoir 90, integral with the handle supplies oil to both sides of a piston 94, the rod 95 of which engages a fork 97 on the lever 88. The valve spindle is rotated by the handle 87, but if the valve is stiff the piston is moved and oil passes into a flexible pipe 102, past an adjustable valve 98, and thence to a conduit 103 which communicates with the moving parts of the valve. In a still further modification, worm 57, Fig. 3, is driven through a second stage reduction 55, and is connected to a doubleacting pump 62. Lubricant is supplied to the valve from a reservoir 63 through valves 66, 68 and conduit 69, 70.
