Title: Vehicle direction indicators
Inventor: SUTHERLAND WILLIAM DRUMMOND
IPC: H05B39/09
Filed: 1956-10-31
Abstract: 816,010. Trafficators. C.A.V. Ltd. Sept. 12, 1957 .[Oct. 31, 1956], No. 33189/56. Class 118(2). A flashing direction-indicating system on road vehicles drawing trailers is arranged so that in the event of failure of a lamp required for signalling a manoeuvre, no signal is given. The driver's selector switch has a part f controlling the vehicle indicators (lv, rv) and a part g ganged to f to control the trailer lamps lt, rt. If both sets of selected lamps are working, the current taken by them flows through relay coils c, d and actuates switches a, b. If one or both sets of lamps have failed, the relay does not operate. A hold-on winding h keeps the relay energized. The current flowing is not sufficient to light the lamps, which are lit through switch k of a flasher unit. Switch m makes a warning light w. The flasher unit is a relay with opposed windings o, p and operates when q is fully charged and no current flows in p., Contact n then opens and q discharges, when the relay is de-energized, n closes, m, and k open and the new cycle begins.

Title: Improvements in photographic reproduction processes
IPC: G03C8/06
Filed: 1956-10-31
Abstract: 840,773. Photographic roll films; migratory transfer processes. KODAK Ltd. Oct. 31, 1956 [Oct. 31, 1955], No. 33317/56. Drawings to Specification. Classes 98(1) and 98(2) Photographic material for migratory transfer comprises an opaque support bearing on one side a light-sensitive silver halide emulsion layer and on the reverse side a receiving layer comprising development nuclei or a silver precipitant and a colloid stabilizer absorbed thereto. After development in the presence of alkali and a silver halide solvent, the support is rolled on itself to effect migratory transfer. The colloid stabilizer may be a silicate or aluminate, saponin, mercaptotetrazole, methylene blue or gelatinous zinc oxide. The development nuclei may be colloidal silver or gold or silver sulphide, and the silver precipitant may be sodium sulphide or solenide, zinc sulphide, aminoguanidine sulphate or carbonate, arsenous oxide, sodium stannite, thiourea or its derivatives, substituted hydrazines, mercaptans or xanthates. The lightsensitive layer may contain a tanning or non- tanning developer, or the developer may be with the alkaline/silver solvent processing solutions. The support may be a white pigmented (e.g. titanium dioxide) cellulose acetate or acetate butyrate, or a water proofed baryta paper which bears a heavily pigmented gelatin coating containing a dark pigment such as carbon, alternatively, the dark pigment may be in the support. The film may be constructed as a roll having a leader and trailer paper but no backing paper, the frame numbers being applied to the receiving layer on the back of the film with a dye such as bis-[l :3-diphenyl-2-thiobarbituric acid- 5]- pentamethine oxonol, which is removed or decolourized during processing. Instead of frame numbers the film may be notched. A white border for the final prints may be obtained by heavily fogging the negative in the border areas or by applying a water-impermeable resist to the border areas of either the negative or the receiving layer. In most of the examples, the receiving layer is prepared by mixing sodium sulphide with lead acetate, zinc nitrate and silver nitrate soluitions in the presence of the colloid stabilizer. Specification 745,445 is referred to.

Title: Improvements in and relating to colour removal from esters
IPC: C07F9/02
Filed: 1949-12-30
Abstract: Esters of alcohols containing at least 6 carbon atoms, or mixtures of such esters, are bleached by exposing them in thin layers (up to 5 mm.) to near ultra-violet light.  If strongly-coloured they are preferably subjected to a preliminary chemical bleach, e.g. with chlorine.  The products are sufficiently free from colour to be used as plasticizers for synthetic resins.  The process is particularly suitable to esters of OXO alcohols with polybasic acids, using layers up to 3 mm. thick exposed to daylight or a high proportion of radiation around 3650  .  Examples show the treatment of di-3 : 5 : 5-trimethylhexyl phthalate.  Other esters that may be treated are tri-3 : 5 : 5-trimethylhexyl orthophosphate, di - 3 : 4 : 5 - trimethylhexyl phthalate, di - 4 : 5 : 5 - trimethylhexyl phthalate, di-3 : 4 : 4-trimethylhexyl phthalate, di-3 : 5 : 5-trimethylhexyl glutarate, di-3 : 5 : 5-trimethylhexyl sebacate and in general phthalates, glutarates and orthophosphates of OXO nonanols, 2-ethylhexanol and C6-C9 OXO alcohols obtained from olefines derived from the cracking of petroleum waxes.  Specification 684,334 is referred to.

Abstract: 5 0 9 , 1 4 4 . Lifting-jacks. NILSON, L. D. Dec. 7, 1937, No. 33877: [Class 78 (iii)] A jack for engaging the bumpers of motor vehicles comprising a cylinder 18 with ball-jointed folding foot 10, and a piston 24 integrally connected by its hollow rod 26 to a guide sleeve 20 closely embracing the cylinder 18. The pump rod 60 is connected to a second guide sleeve 68 closely embracing the upper part of the sleeve 20. On raising the rod 60 a vacuum is formed in the chamber 38, thus causing the oil in the upper part of the chambers to force the valve 48 off its seat against the pressure of the spring 52 and admit oil to the chamber 38 through the ports 70. On the return stroke the valve 48 is reclosed and the valve 54 forced open to deliver the oil below the piston 24. A byepass 44 limits the lift of the piston. To lower, the rod 60 is depressed further than usual so that it first opens the valve 48 positively by direct contact therewith. Afterwards, by rotating the rod 60 at' this depth, screw mechanism 72 is brought into action to lower it further and so cause the tail-piece of the valve 48 to engage and depress the valve 54 to any desired extent so that controlled lowering occurs under the weight of the load. A bumper-engaging crutch is secured at any desired height on the member 20 by a split clamping sleeve.
