Filed: 1926-09-01
Abstract: 269,393. Campbell, G. Sept. 1, 1926. Press - button switches; switches, latching and unlatching.-A vehicle. direction indicator comprises two manually-operated switches associated with individual signalling circuits and with common locking means which locks either switch in its " on " position, these locking means being disengaged by the steering mechanism when the latter is returned to " straight." The switch casing 2 is supported by an arm 3 on the dashboard 4 and may be adjusted by means of knuckles 6, 7 and rounded nuts 9. The switches 11, 12 are mounted in the front 10 of the casing and close contacts 15. Each switch has a portion 25 having a conical face and a shoulder to coact with a plate 18 which is slotted at 19 to pivot about points 20 or 21. A spring 22 is connected at one end to this plate and at the other end 23 to the cover 10. If the left-hand switch 11 is depressed its conical face 25 swings the plate 18 clockwise about the pivot 20 and this plate then snaps in behind the shoulder of part 25 locking the switch " on." The steering wheel 1 carries lugs 28, 29 co-operating with a pin 30 on the plate 18. When the wheel is swung to the left the pin 29 wipes past the pin 30 rocking the plate 18 about the pivot 21 without unlocking the switch 11. On the return of the wheel to the right the pin 29 rocks the plate 18 about the pivot 20 releasing the switch 11 which is returned by its spring 16. If the wheel is not turned sufficiently for the pin 29 to wipe past the pin 30 the plate 18 may be released by hand by means of the pin 30. A pilot light 31 showing through a window 32 is used to indicate if the switch has acted properly, the battery circuit of this lamp being closed by means of a relay 33 in series with the usual indicator 36

Title: An improved method and apparatus for attaching connections to stranded cables
IPC: D07B9/00
Filed: 1944-11-03
Abstract: 601,670. Jointing by stamping. STREADER, W. J., TATE, A., and TATE, A. E. Nov. 3, 1944, No. 21611. [Class 83 (iv)] [Also in Group XXXVI] Dies.-A method of attaching a sleeve of ductile metal to a stranded cable consists in subjecting the sleeve to radial pressure over one or more areas extending partly around the circumference of the sleeve while the areas immediately flanking the first said area or areas are embraced by curved surfaces either during the whole of the pressure period or at or slightly before the conclusion thereof. In one form, the invention is described in connection with the attachment of separate anchoring sleeves to the steel core 11 and aluminium stranded sheath 17 of an electric power cable. A sleeve of ductile mild steel 13, Fig. 1, carrying a forked securing member 12 is placed over an end 11 of the core from which the aluminium sheath has been stripped and is secured to the core by means of indentations pressed into the sleeve so that the metal of the sleeve fills the gaps between the strands of the cable at the points of indentation. A sleeve 16 of aluminium carrying a forked securing member 15 is similarly jointed to the aluminium sheath 17 so that the two securing members 12 and 15 are in register. Fig. 2 shows a method of joining two ends of a cable. A sleeve 19 of mild steel is secured to the two ends of the core 11 and an aluminium sleeve 20 is secured over the sleeve 19 and to the two ends of the aluminium sheathing 17, which it overlaps. The radial indentations are produced by means of a two-part die each part having a semi-cylindrical groove with upstanding projections adapted to form the indentations when the two halves of the die are closed on to the sleeve. Alternatively, as shown in Fig. 4 each part 22 of the die of greater length than the sleeve has a radial slot extending outwards from the cylindrical groove. In this slot is mounted a key having an inner edge formed with crests 24 and troughs 25, the crests of one key being opposite the troughs of another. The depth to which the crests may project into the cylindrical space of the die is determined by heads 28 formed on the outer edge of each key.

Patent GB-786225-A (GB)
Title: Improvements in or relating to the refining of petroleum hydrocarbons
IPC: C10G27/10
Filed: 1955-07-28
Abstract: Metallic compounds contained in petroleum hydrocarbons are eliminated by forming in situ in the hydrocarbons, by adding an alkyl iminophenol, an organo-metallic compound with chelate links, and decomposing the chelate by contact with a solid compound having an acid reaction.  The iminophenol may be obtained by condensation of an o-hydroxy-benzaldehyde with a diamine. Chelates present in petroleum fractions after a sweetening treatment by oxidation of the mercaptans by a free oxygencontaining gas in the presence of a chelate compound obtained by reaction of an alkyl iminophenol with a Group VIII metal, may be similarly decomposed.  The decomposition may be effected by filtration of the hydrocarbons through the solid compound, such as a crystalline acid salt, e.g. an alkali or alkaline earth acid sulphate or acid phosphate, an alkali acid fluoride or ammonium bifluoride. The crystalline salt may be mixed with an inert filler such as coke or a neutral salt, e.g. sodium chloride.  In the formation of the chelate in situ the metals to be eliminated are preferably present in an ionizable form, e.g. as the chloride, oleate, stearate, naphthenate, enolate or cresolate.  In an example, petrol is sweetened by stirring with an aqueous solution containing cupric chloride, sodium chloride and hydrochloric acid, and the sweetened petrol, after addition of disalicylal propylene diamine, filtered through sodium bisulphate. In the application of the process to the decomposition of added chelates, examples are given of (1) sweetening thermally cracked petrol by adding disalicylal propylene diimino cobalt and lead cresolate and filtering the sweetened petrol through a mixture of sodium bisulphate and sodium chloride; (2) sweetening kerosene as in (1), including an alkaline wash to remove cresols prior to filtration; and (3) sweetening kerosene by adding a solution of disalicylal propylene diimino cobalt and lead naphthenate in an aromatic petroleum solvent and filtering the sweetened kerosene through acid sodium phosphate or ammonium bifluoride.
