Filed: 1946-11-04
Abstract: 621,819. Signs. YATES, H. R. Nov. 4, 1946. No. 32642. Convention date, April 25. [Class 3(ii)] A sign comprises a carrier interchangeably mounting a row of units detachably connected both mechanically and electrically, each of the two end units of the row, having a projecting jack received in a socket in the carrier, the secondary of a transformer being connected across the sockets and the primary of the transformer having a switch spring-biased to its "off" position and moved to "on" position by the row of units as the jacks enter the sockets. As shown in Fig. 1, a base 10 supports pairs of pillars 11 which have channels 12 for removable trays 13, each of which carries a row of interchangeable sign units 14. The units 14, Fig. 6, each comprise a rectangular casing 15 made of insulating material, and are either hollow or filled with a hardening plastic. When they are hollow a back cover is provided. Mounted on the front is a discharge tube bent to the shape of the required symbol, one end being connected to a plug 23 on a side 25 and the other to a socket 22 on the opposite side 24. The plug of one unit is arranged to engage the socket of an adjacent unit and an insulating sleeve 56 is used to protect the joint against the weather. A resistor 27 may be connected in series with the tube so that each sign element has the same resistance. The units are slidably mounted in the tray 13 which is of channel-section and has flanges 28, Fig. 3, to retain the units in the channel. Dummy units having no discharge tube but with the plug and socket connected by a resistor are used to fill any spaces. At each end of the tray 13, end-connecting units 30 are used. One of these has a plug 33 for engaging the socket 22 of the adjacent unit and the other has a socket 32 for engaging the plug 23 of the unit at that end. The members 32, 33, are connected to plugs 36 which protrude from the base of the tray 13 and which engage insulated sockets 38 mounted within the channels 12 on the base 10. The plugs 38 are connected to the high voltage secondary of a transformer 42, so that the units 14 are series connected. The primary 42 of the transformer is connected to the supply mains through a switch 45 which is actuated by the tray 13 when in position in the channels 12. The plugs 36 are of such length that they make contact with the sockets 38 before the switch is actuated. An insulating sleeve covers the portion of each plug 36 which still projects when the switch is actuated. In a modification, the trays 13 may have plugs 36 which protrude from the back instead of the base. With this construction several trays are mounted one above the other in a casing to form a hanging sign, the trays being replaceable from the front and plugging into contact strips at the rear. The trays are kept in position by a screw-on frame. In either construction the trays 13 may be omitted in which case the plug and socket connections are relied upon for rigidity.

Title: Improvements relating to the manufacture of filaments
IPC: C07F7/00
Filed: 1962-08-30
Abstract: 965,729. Composite filaments. SOC. DE LA VISCOSE SUISSE. Aug. 30, 1962 [Sept. 9, 1961], No. 33409/62. Heading B5B. Composite filaments and yarns are made by melt-spinning two polymers of different melt viscosities side by side through the same spinneret orifice, the molten components being excluded at an inclination to the vertical centre line of the die body, opposite to the deflection caused by the difference in viscosities. The filaments are extruded through a die body in which the orifice capillaries are inclined with respect to the vertical centre line. In a multi-orifice spinneret, some or all of the orifice capillaries may be thus inclined. In an example, two polyhexamethylene adipamides of different melt viscosities are brought together from separate chambers and are spun, side by side without mixing, through a die body (Fig. 2) having spinneret orifices whose capillaries 9 make an angle # (30-45 degrees) with the vertical centre line. The angle of deflection α of the resulting composite filaments 8 is less than if the capillaries had been perpendicular to the face of the die. This reduction in the deflection angle permits the spinning of polymers of widely differing melt viscosities to form composite filaments capable of a high degree of crimp. Specifications 580,764, 874,808 and 884,163 are referred to.

A toy vehicle track set comprises two different tracks 5 and 7 for toy vehicles driven by rotating coil springs 9, 9<SP>1</SP> respectively set into the tracks and engaged by driving pins 10 projecting from the vehicle undersides, track 5 is traversed by carrier vehicles 6, and track 7 is traversed by transportable vehicles 8. The latter vehicles 8 can be loaded and unloaded onto the carrier vehicles 6 at a loading and unloading station, 16 and 15, respectively. The loading station 16 has an access ramp 19 at one end and the unloading station 15 has an exit ramp 17 at the other end of track 5 which carries the carrier vehicles 6, and the other track 7 runs at one end onto the access ramp 19 of the loading station 16 and at the other end onto the exit ramp 17 of the unloading station 15. The carrier vehicles may be a train comprising a locomotive 31 and railway platform wagons 30, 30<SP>1</SP>, 30<SP>11</SP> and the wagons are interconnected and coupled to the locomotive by coupling strips 36, and the transportable vehicles may be toy motor cars. The loading platforms 32 are roughly flush with the ends of the ramps 17 and 19, and like the ramps, have a slot 33 for accommodating the driving pins 10. The platforms also have tracks 34 for the wheels 35 of the toy cars 8, and the rear ends 52 which cooperate with the access ramp are slightly flared and the tracks near the leading end curve to the side to register with the end of the exit ramp. The front end of the leading wagon 30<SP>1</SP> and the rear end of the last wagon 30<SP>11</SP> are provided with catches 37 and 38 respectively to prevent the cars from rolling off the wagons. The catch is released when the horizontal lever arm 41 of the cranked lever is raised since this causes the vertical end 40 to be lowered to clear the slot 33 for the pin 10. The rear catch is released by an abutment 53 which projects into the path of the catch when the rear wagon is backed against the access ramp, and the front end catch is manually releasable. For controlling the loading and unloading operations each ramp is provided with a catch 24, 25 for intercepting the motor cars and comprises a manually tiltable lever 28 having two relatively spaced projections 29 which are alternately tiltable into the slot 21 in the ramp for intercepting the driving pins 10 of the cars. The coil springs 9 and 9<SP>1</SP> may be rotated by a miniature electric motor and a source of power in a housing 11. A lever 12 permits the motor to be started and stopped, whereas levers 13 and 14 permit the drive to be selectively applied to one or both of the coiled springs.
Patent GB-834767-A (GB)
Title: Method of refining petroleum
IPC: C10G17/09
Filed: 1958-10-21
Abstract: Petroleum oils are refined by first mixing the oil in the liquid phase with an organic carboxylic acid anhydride, subsequently agitating the mixture with a concentrated aqueous alkali hydroxide solution and separating the treated oil from the alkali and the reaction products.  The time interval between the anhydride and alkali treatments is unimportant and may be seconds, hours or days. The preferred anhydride is acetic, others mentioned being propionic, butyric, benzoic and phthalic-an oil-miscible solvent, e.g. benzole, being used with the solid anhydrides.  Alkalis mentioned are sodium and potassium hydroxides; preferably as not less than 35% solutions. Generally, 0.02 to 0.50 vol per cent of anhydride and 5 to 25 vol. per cent of alkali will be used.  The process is usually operated at normal temperature and pressure except for treating very volatile fractions when the pressure may be increased.  Before treatment the oil may be dehydrated, e.g. with concentrated brine, calcium chloride or rock salt.  After the alkali treatment settling gives three phases, an upper purified oil layer, a small middle layer of impurities, and a lower alkali layer also containing dissolved acetate, which is recycled with occasional concentration and removal of acetate.  In an example, 5000 barrels per day of a mixture of 70% catalytic cycle oil and 30% straight run lighter gas oil is treated with 0.05% by vol. of acetic anhydride and then after 15 seconds with 12% by volume of 44.2 DEG  B<\>ae sodium hydroxide.  The process may be applied to distillate fractions, or to crude oil prior to distillation.
