Title: Improvements relating to electro-magnetic carbon-pile regulators
IPC: H02P9/22
Filed: 1935-02-01
Abstract: 451,232. Resistance regulation. STONE & CO., Ltd., J., Deptford, London, and OGILVIE, G. P., 44, Tweedy Road, Bromley, Kent. Feb. 1, 1935, No. 3306. [Class 38 (iv)] In carbon pile resistance regulators in which the pressure depends upon a rotor located between the poles of the controlling electromagnet, the whole of the mechanism, including the magnet rotor, spring system and carbon pile, is mounted as a bodily removable unit upon the base or panel. The rotor 1, Figs. 1 and 2, is arranged between the poles of the electromagnet 5 having a winding 6; its shaft 2 at one end applies pressure to the carbon pile 9 and at the other end is acted upon by a spring 12, the arrangement being generally similar to that shown in Specification 438,440. The bearing brackets 3 for the shaft 2 are secured to the sides of the magnet 5 upon which is also secured by screws 33, a bridge-like member 32 arranged to straddle the winding 6 and to support the spring system and carbon pile. The electromagnet 5 is secured by screws to the base 10. The anchorage bracket 11 for the spring 12 is adjustably mounted upon an arm extending from the member 32. A dashpot 36 may also be carried by an arm 37. Pile compression resetting means arranged between the abutment plate 19 and a bracket 38 on the bridge member 32 includes a universal connection and a two armed lever 41, showing also in Fig. 4, which is normally locked in position by a screw 47 passing through arcuate slots in the lever but is re-set from time to time by releasing the screw and allowing the spring 45 to readjust the lever which is then again locked in position by the screw.

Patent GB-491781-A (GB)
Title: Improvements in or relating to the production of anti-friction bearing members of hardened steel
IPC: F16C33/64
Filed: 1937-02-04
Abstract: In the production of an anti-friction bearing member of hardened steel, the member or part of it is after a heat-treatment to produce in the finished member a Brinell hardness of at least 600, subjected to a temperature lower than indoor temperature, e.g. below 0 DEG  C., for a period of time to ensure that macro-stresses of the character of tensile stresses in directions parallel to the surface, are, when the temperature of the cooled member is subsequently raised to 100-300 DEG  C., preferably 200-250 DEG  C., either eliminated or rendered very small at that part of the member stressed by the load during use.  Before or after the member is subjected to the low temperature, it may be allowed to remain in contact with a surrounding fluid at atmospheric temperature for a period of time in excess of that required to enable the member to assume atmospheric temperature. The member may be cooled to a temperature of -50 DEG  C. or to a temperature between 50 and -100 DEG  C. and the temperature may be allowed to fall continuously from the hardening temperature or in stages.  The member may be subjected during cooling to vibration, produced for example by the action of a periodically varying electromagnetic field produced by an electromagnetic oscillation circuit or by the application of pressure thereto in order to effect a desired modification of the macro-stresses.  When treating a plurality of members, a member after cooling may be reheated to an intermediate temperature by immersion in a medium for cooling other members to that temperature.  In an example, a member made of steel containing 1 per cent of carbon, 1 of chromium and 1 of manganese is quenched from 800-900 DEG  C., preferably 850 DEG  C., to indoor temperature in oil and then cooled in a suitable liquid, e.g. alcohol to -20 to -40 DEG  C.  The member is then transferred to another bath, e.g. of solid carbon dioxide, at -78 DEG  C., transferred to the first bath and then reheated to an intermediate cooling temperature.  The member is then heated to a temperature above 150 DEG  C., preferably 200-250 DEG  C.  If desired, the cooling may take place in stages to temperatures of -25, -50, -75 and 100 DEG  C. after hardening.

Title: Device for mutually adjusting two rotating cylinders in circumferential direction
IPC: B41F13/14
Filed: 1943-03-02
Abstract: 565,749. Printing-machines. BEWEG AKT.-GES. March 2, 1943, No. 3424. Convention date, Feb. 5, 1942. [Class 100 (ii)] To enable relative circumferential adjustment of two cylinders of a machine such as a rotary offset machine to be effected while the machine is in motion, the gear 2 of the offset cylinder 1 is driven from an annular gear 6 keyed to the shaft 4 of the forme cylinder 3 by means of a pair of gears 10, 11 on the same axle and of unequal size. These gears are mounted in a member 7 which is freely mounted, but is normally held fixed by means of teeth 8 engaged by a gear 12 on a shaft 23 fitted with a worm-wheel 13 geared to a self-locking worm 14. The gears 10, 11 normally act as ordinary gears and transmit motion from gear 6 to a similar freely-mounted gear 5 engaging gear 2 of the offset cylinder. By rotating the worm 14 by a crank-handle 16, the member 7 is rotated and the gears 10, 11 act as planetary gears and relative circumferential motion takes place between the cylinders 1, 3. The worm 14 can effect the adjustment while the machine is running, and the adjustment is a fine one. For larger adjustments while the machine is at rest, the shaft 23 can be operated directly by a hand-crank 25. The Specification as open to inspection under Sect. 91 states that the planetary gears may be replaced by other differential gears. This subject-matter does not appear in the Specification as accepted.

Addition to 383,330. [Class 98 (ii).] Leads prepared according to the process described in the parent Specification are coloured by means of a colouring-material which is soluble in the agent employed for fixing the marks, and are also preliminarily coloured with a fat-soluble colouring-material. The colouring-material is preferably a Sudan dyestuff, particularly Sudan yellow, which is soluble in spirit used as the solvent for the fixing-agent, e.g. shellac. The fixing-agent is applied in two or three very thin coats, so that the solvent evaporates before the colouring-matter can spread in the solvent beyond the marks. The leads are preliminarily coloured by soaking in a solution of a fatsoluble dyestuff, e.g. Sudan yellow, in a solvent which is thinly liquid at ordinary temperature, such as spirit, benzine or the like, and after removal of the solvent, they are treated with the fatty mass according to the parent Specification.

As shown in Fig. 1, the motor housing 9 is mounted on a gear housing 6 carried by the engine crank-case 11, and on the armature shaft 12 is mounted a disc 16 which carries planet pinions each having two sets of gear teeth 23, 24, preferably differing in number. The teeth 23 engage a fixed internal gear ring 38 and the teeth 24 engage an internal gear 40 mounted on a hollow drive shaft 41. The outer end of the shaft 41 carries a disc 46 on which are pivoted at 52, 53 the radially movable clutch members 50, 51, Figs. 1 and 2, having arcuate rims 54, 55 provided with friction material for engagement with the inner face of a drum 48 on the engine shaft 5.
