Title: Improving the filtration characteristics of pibsa/pe esterification products
IPC: C08G63/90
Filed: 1978-06-30
Abstract: In a process for the production of an ester composition by reacting an excess of pentaerythritol with polyisobutene succinic acid or anhydride under esterification reaction conditions and thereafter filtering the crude ester product so produced to remove insoluble matter the filtration rate is significantly improved by washing the crude product with water, to cause aggregation of pentaerythritol fines prior to filtering. In a preferred embodiment a water soluble organic solvent, eg. pyridine or methylisobutyl ketone is included in the wash to promote contact between the water and insoluble matter. The invention is particularly applicable to the production of ester compositions having a high total hydroxyl to ester group ratio.

Title: Process for alkylating waxy hydrocarbons
IPC: C10G50/02
Filed: 1978-08-04
Abstract: Waxy, normally solid hydrocarbons are alkylated to form liquid hydrocarbons boiling in the lube oil range by contacting the wax and a low molecular weight olefin, such as ethylene, with a catalyst comprising a C3-C5 carbon atom secondary alcohol at elevated temperature and pressure.

Patent GB-2032249-A (GB)
Title: Improvements in jewellery bracelets
IPC: A44C5/00
Filed: 1978-10-19
Abstract: A cross-weave or polynese bracelet is tapered by progressively increasing the number of turns or convolutions of some or all the helices 12, 14, 16 which constitute the tapered zone. The increase may be made alternately on opposite side edges of the zone or symmetrically, and by different amounts according to the rate of taper required. All helices are wound to the same pitch w in the same size r of stock material, thus obviating the cost and complexity inherent in the use of different sizes of stock material to produce the taper. It is also possible to achieve a higher rate of taper than can be achieved by lateral squeezing of a series of helices of identical size initially wound to a pitch more than twice the width of the ribbon. <IMAGE>

Title: Dual-flush valve-discharge cisterns
IPC: E03D1/14
Filed: 1979-04-26
Abstract: In a dual flush w.c. cistern for handle or pedal actuation, a discharge valve lever 1, lifted by actuating rod 21, engages two parallel latching arms 8, 9 which are pivoted at 10 and are biassed anticlockwise by respective floats 15, 14 positioned at different cistern levels. The latching arms have cam surfaces 17, 18 and seating abutments 19, 16. For a partial flush the lever 1 is raised only sufficiently (Fig. 3, not shown) to ride up cam surface 18 and seat on abutment 16, so that the valve 4 is held open until the cistern water level descends below the upper float 14, thereby allowing the arm 9 to swing clockwise under gravity to release lever 1 and so allow valve 4 to close. For a full flush the arm 1 must be raised beyond abutment 16 to ride up cam surface 17 and seat as shown on the abutment 19 of arm 8 so that the valve 4 is now held open until the cistern empties below float 15. <IMAGE>
