IPC: C07D295/096
Filed: 1975-05-22
Abstract: The compounds correspond to the formula <IMAGE> in which A is lower alkylene, R1 is lower alkyl, cycloalkyl, aryl, ar(lower)alkyl, a heterocyclic group or a radical -A-C6H4-OCR3R4R5, R2 is hydrogen or the meanings of R1, R3 and R4 are hydrogen or lower alkyl, R5 is carboxyl or esterified carboxyl and R6 is hydrogen or lower alkoxy; R1 and R2 together can also be lower alkylene. The compounds and their salts can be used for the treatment of hyperlipidaemia. They are prepared by reacting an appropriately substituted phenol with a compound YCR3R4R5 in which Y is an acid radical. After this it is possible for resulting carboxylic acids to be esterified by lower alkyl, esterified carboxyl groups to be converted into free carboxyl groups, carboxyl and esterified carboxyl groups to be reduced to hydroxymethyl and lower alkoxy groups R6 to be dealkylated.

Patent GB-403762-A (GB)
Title: Improvements in the manufacture and production of chrome yellow colours which are stable to light
IPC: C09C1/20
Filed: 1932-08-08
Abstract: Chrome yellow colours stable to light are produced by precipitating a material comprising normal lead chromate and heating the rhombic crystals obtained in an aqueous and at the most slightly acid medium at a temperature above that at which conversion to the monoclinic modification occurs until the said conversion is practically complete.  Salts forming an isodimorphous series of mixed crystals with lead chromate and capable also of being converted from the rhombic to the monoclinic form may be precipitated with the lead chromate; such salts are lead sulphate and the chromates and sulphates of barium, strontium and calcium.  Precipitation is preferably effected in the presence of just sufficient acid to obtain, after conversion, monoclinic crystals having a maximum sedimentation volume; advantageously also lead salt solutions having the same pH value as the precipitating agent are used.  The conversion step may be effected in the presence of extenders such as aluminium hydrate or baryta.  Examples are given relating to the precipitation and conversion of lead chromate, and of mixed crystals of lead chromate with lead sulphate, with lead sulphate and strontium sulphate and chromate, with strontium chromate, and with lead sulphate and barium chromate and sulphate.  The conversion temperatures used range from 25--60 DEG  C., the time for conversion decreasing with increase of temperature, say from 10 to 2 hours.

Title: Improvements in and relating to methods of automatically showing when tennis nets and the like have been adjusted to the correct height
IPC: A63B61/04
Filed: 1923-09-04
Abstract: 225,302. Graham, J. E. Sept. 4, 1923. Nets.-To show when a tennis net or the like is adjusted to the correct height means are provided for connecting the upper edge of the net, at or about the centre, to an indicator. A non- extensible strip 11, Fig. 1, passing over the net, hooks on to a circular plate 13 carrying a pointer 25. A slide 15 on the circular plate is anchored to the ground or held down by a weight 19, and has a pin and slot connection with the pointer. Thus the relative movement of the circular plate and the slide 15 due to variation in the height of the net produces a rotation of the pointer. In a modification, Fig. 7, a hook 33, connected to the top of the net is pulled down by a spring or weight contained within a heavy casing 32 and the position of the hook is indicated on a quadrant-shaped surface 36 by a bent pointer 35. In a further modification, the indicator is placed on the winding-up post and is connected to the. centre of the net by a cable passing round pulleys.

Title: Electrical lubrication of detergent shaping devices
IPC: C11D13/14
Filed: 1949-08-26
Abstract: <PICT:0676377/III/1> During the formation of detergent compositions into bars, for example by cutting with wires or knives, extrusion through orifices, moulding or stamping, a direct electric current is passed across the interface between the plastic detergent composition and the shaping device.  The passage of the current has a lubricating effect and increases the firmness, skin smoothness and toughness of the bar.  The detergent compositions may comprise detergents of the anionic or cationic type, and may also contain building agents, improving agents, or organic dispersing media such as superfatting agents.  Where the bars are formed by moulding, batch moulds for individual bars or those moulds, for large bars or blocks, commonly referred to as frames may be employed.  Alternatively continuous moulding devices may be employed wherein the moulds may comprise endless belts or a plurality of interlocking segments.  In Fig. 3, an agitation and extrusion apparatus has one electrode formed by the metal body 20, an electrical connection being made at bolt 21.  The metal orifice plate is clamped between plates 12 and 13 of insulating material and forms the second electrode, an electrical connection being made at lug 15 connected to the orifice plate.
