Filed: 1918-02-25
Abstract: 123,411. Scott, H. A. Feb. 25, 1918. Equalizing load on generator; switching systems.-In an electric supply system normally fed from a generator 1, on overload, an auxiliary generator 21 is automatically switched in by means of an electro-magnetic switch 17, whose circuit is closed by a relay 6 in the main supply lines. When the generator 21 is supplying, a switch 20 closes a holding- circuit for the switch 17 and makes it independent of the switch 6. On excessive overload, the circuit of the switch 17 is opened at the contacts 12, 13 by the coil 16; all the load is then thrown on the generator 1 and the main overload circuit-breaker 4 acts. After a moderate overload, as the demand falls the switch 6 having previously opened-the generator 21 is disconnected by the holding-on switch 20 opening, and thereby de-energizing the switch 17.

Patent GB-470078-A (GB)
Title: Improvements in the manufacture and production of high-grade lubricating oils
IPC: C10G21/00
Filed: 1936-02-07
Abstract: Lubricating-oils are obtained from asphaltic-base crude oils or fractions thereof by first treating with liquefied normally-gaseous hydrocarbons, whereby asphalt is separated, then treating the oil with the same or a similar solvent at or near the critical temperature, whereby separation in light and heavy fractions is effected, and finally extracting the heavy fraction with a selective solvent.  Solvents for the first two stages are; propane, ethane or mixtures thereof.  Solvents for the last stage are: aniline, phenol, furfurol, ketones, ketonic acids, nitrobenzene, or liquid sulphur dioxide, alone or in the presence of propane.  In an example, a Wietze or similar crude asphaltic oil is treated at ordinary temperatures or up to 40 DEG  C. with propane, and after removal of asphalt, the temperature of the solution is raised to 95 DEG  C. Refined lubricating-oil remains in solution and is removed and recovered; the heavy fraction precipitated is freed from solvent and heated to 50 DEG  C. with crude cresol.  The extract is removed, and the raffinate fraction consisting of hydrocarbons rich in hydrogen is freed from solvent and mixed with the lubricating-oil obtained in the second stage.

Title: Improvements in and relating to protective systems for alternating current circuits and apparatus therefor
IPC: H02H1/00
Filed: 1942-03-23
Abstract: 556,014. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). March 23, 1942, No. 3857. [Class 38 (v)] A distance-protective system having the same reach for all types of faults, as in Specification 554,667, differs from the system of the latter Specification in that the connections of the voltage windings only are changed, by means responsive to negative phase sequence components of voltage operating on line-to-line to make the system response on such faults the same as for the other faults. The underlying theory is given and is adapted from that set out in the said Specification. Impedance relays 16 A .. C of the balanced-beam type are energized voltage windings 30 connected to the secondary windings 28 of a voltage transformer 26 so as normally to be energized by the voltage - to - earth of the respective lines, the windings being also connected, but normally ineffectively, to the delta voltages in series with impedances 37 which absorb half the delta voltage. Each beam is also acted upon by a line current winding 32 and by a winding 33, the latter being energized in series by a portion of the residual current adjustable by an autotransformer tapping 36. This arrangement is shown to give the same reach for three-phase, and single- and double-line-to-earth faults. Since a line-to-line fault produces negative phase sequence components only, the voltage-coil connections are changed to delta voltages by means of a relay 39 the winding 41 which is energised from the secondary 28 over a negative phase sequence mesh 42, 43, and opens contacts 40 to render the delta voltages effective. Since earth faults also may produce three negative components as well as zero components, relay 39 is rendered ineffective, if the latter components are present, by a residual-voltage relay 44 connected in the neutral lead as shown, or energized from an open-delta tertiary winding (not shown) on transformer 26. Tripping is also subject to a directional relay having current windings 23 and voltage windings 25 arranged as in Fig. 8 of Specification 508,005. The Specification refers also to discrimination between the different types of fault by means of power-directional relays responsive to positive, negative, or zero components.

Abstract: 1,217,202. Indexing; feeding workpieces; tool-holders. GEORGE F. CLARK & SONS (TOOLMAKERS) Ltd. 16 Jan., 1969 [25 Jan., 1968], No. 3988/68. Headings B3B and B3W. In a dial feeder for, e.g. a press, of the kind having a rotatable disc with a plurality of work- or tool-locating stations adjacent its periphery, the disc including ratchet means and being rotatable by a pawl carried on a slide, an indexing pin movable normal to the plane of the disc into and out of engagement with successive holes in the disc is driven from the slide so as to lock the disc whilst a station is at the work position and so that the disc is free whilst a station is being moved to the work position. A disc 1 with holes 2 for receiving workpieces is rotated about a bearing 4, 5 on a bed 3 by the engagement with ratchet teeth 32 on the disc of a spring-loaded pawl 31 mounted on a slide 26 which is reciprocated in a dovetail groove 25 in an extension 24 of the bed 3 by means of a push-rod 30 and bell-crank lever (not shown) pivoted to an eccentric driven from the press. For accurate indexing holes 34 are provided in the disc at the same spacing as the holes 2 and a pin 37 located in an aperture 38 in the bed is moved to enter a hole 34 when a hole 2 is in registration with the tool. The pin 37 is pivoted to an arm 17 which is upwardly spring-loaded at (21), Fig. 2 (not shown), but is depressed between successive registrations of holes 2 with the tool by engagement of a cam roller 40 on the arm with a cam surface (39) on the slide 26. A spring-loaded pawl 43 carries an upstanding pin 50 which rides over the ratchet teeth when the disc 1 is rotated in the counterclockwise, operative direction and engages a ratchet tooth to prevent rotation in the opposite direction. Compression springs (23) in four equi-spaced holes in the underside of the bed exerts a downward pressure on a plate 11 clamped to the bearing 4, 5 so as to provide some friction in the notation of the disc to prevent its overrunning. The bed 3 is mounted on the press at adjustable height by means of brackets (51) with elongated screw holes. In an alternative embodiment, Figs. 3-5 (not shown), brackets (63) have slots allowing vertical and horizontal adjustment of the bed 3 relative to the press. The push-rod 30 is omitted and one arm of a bell-crank lever engages directly in a slot in the slide, the other being engaged by a reciprocating part of the press.
