Patent GB-434295-A (GB)
Title: A process for improving lubricating oils
IPC: C10M171/00
Filed: 1934-06-08
Abstract: Lubricating-oils are improved as regards turbidity, setting point and colour, by an addition, e.g. 0,05--3 per cent of an oil-soluble vacuum residue, solid at ordinary temperatures, derived from de-asphalted hydrocarbon products containing cyclic constituents, e.g. tar, asphalt-basic or mixed basic mineral oils, especially from hydrogenation products or from destructive hydrogenation of coals or coal tars.  The initial material is treated with flocculents, e.g. benzine, gas oil or liquefied normally gaseous hydrocarbons to precipitate asphalts, and, after separation, the oil is subjected to vacuum distillation, preferably up to 300--350 DEG  C. and under a pressure of 78 mm. mercury.  In an example, a destructive hydrogenation product boiling above 350 DEG  C. is treated with benzene and centrifuged to separate solid constituents, then with a light benzine containing petroleum ether, to separate asphalt, after which the larger portion of the precipitant is distilled off and the mixture is then refined with sulphuric acid followed by caustic soda; the washed and dried oil is distilled up to 350 DEG  C. under a pressure of 8 mm. mercury yielding a red-brown resin as residue.

Abstract: 812,653. Hydraulic brakes. DUBONNET, A. May 29, 1957 [June 28, 1956], No. 17065/57. Class 103 (1). A master cylinder device for hydraulic brakes incorporating a means for taking up lining wear and maintaining a constant length of pedal stroke, has a main piston 11, the limits for movement of which are determined by a stop 12 engaging a recess therein. If the main piston has reached the limits of its travel before the shoes are in full contact with the brake drum, the piston part 2 continues to move, separating from the part 11 to leave a recess 14 therebetween into which liquid is sucked past ball valve 7 by way of reservoir pipe 4. On release of the brakes, the liquid sucked in is transferred to the system in front of piston 2 past ball valve 16, thus preventing release of the brakes more than a certain amount. An opening 6, with a ball valve 3, allows flow to take place from the space in front of the piston 2 if the pressure is sufficient to overcome the spring 5.

Filed: 1936-06-19
Abstract: 475,672. Vehicle collision - guards. GARDU, Ltd., and TERRY, C. D. June 19, 1936, No. 17141. [Class 103 (ii)] [Also in Group XXXIV, Means for applying the brakes of a vehicle by the contact of a bumper bar or fender with an obstruction or by other emergency control comprises a coiled spring arranged to operate axially between two members normally restrained by a detent against relative rectilinear movement the whole being located between the tread and lever portion of a brake pedal. The tread 15 and the lever 12 of a brake pedal are secured respectively to a tube 13 and a rod 11. A spring. 19 abuts on the tread and on a block 16 slidable on the tube 13 and secured by a pin 17 to the rod 11, the pin passing through a slot in the tube. A detent 27 pivoted at 31 upon a bracket 20 secured to the tube 13 normally engages a notch 32 in the rod 11 to hold the spring compressed as shown. Operation of a Bowden cable 22 connected to a lever 24 pivoted at 28 on the bracket 20 for example, in the event of a collision or by an emergency control, disengages the detent 27 by the engagement of a pin 33 on the lever 24 with the side 34 of a slot in the detent. The expansion of the spring then brings the bracket 20 against the floor boards 14 and at the same time moves the rod 11 and lever 12 in the other direction to apply the brakes. Upon depressing the pedal the spring is recompressed and the detent 27 re-engages the rod 11 under the action of a spring 37. Accidental disengagement of the detent is prevented by the engagement of the pin 33 with a step 35 in the slot in the detent. The ignition circuit of the engine may be broken or other device be operated when the brakes are applied by a Bowden cable 22 connected to a lever 25 pivoted at 29 on the bracket 20 and actuated by engagement of a pin 38 on the rod 11 with the curved end of the lever which is locked in the actuated position until the return of the pin by the engagement of teeth 40, 41 on the lever and a spring-urged arm 26 controlled by the pin. In a modification the detent is controlled by a threearmed lever one arm of which normally holds the detent against disengagement and a second effects disengagement when the lever is operated by a cable connected to the third arm. A lever corresponding to the lever 25 is in this case operated by a cam surface on the rod 11, also provision is made for adjusting the compression of the spring bv screwing or unscrewing the tread on the tube 13. Specification 433,054, [Group XXXIV], is referred to.
