Filed: 1930-08-23
Abstract: 361,007. Heating water. WRIGHT, A., 28, Lingfield Avenue, Kingston-on- Thames, and OSBORN, H. J., Haytor, Danbury, Essex. Aug. 23, 1930, No. 25202. [Class 64 (i).] In a water heater, scale deposit on the heating element or the chamber containing it is reduced by providing a condensing surface which returns the condensate to the chamber containing the heating element so that the latter is in contact only with soft water. In Fig. 1, the storage vessel 2 is provided with a conical cover 3 which conducts condensate into the chamber 1 containing an electric heating element 11 and thermostat 12. A filling tube 9 with cap 10 is provided. Heated water is drawn off through a pipe 7 surrounded by a pipe 6 perforated at 8 just below the top of the pipe 7. In a modification, Fig. 2 (not shown), a water-supply tank is arranged above the tank 2 to which it is connected by water and air inlet pipes. In another modification, Fig. 3 (not shown), the heating chamber 1 surrounds the storage chamber 2 and is heated by electric heaters around its lower part. In another modification, Fig. 4 (not shown), an additional condensing surface is provided in the form of a cylinder arranged above the conical cover. In another modification, Fig. 5, heating is effected by a gas burner 21 surrounded by a flue 20.

Patent GB-494616-A (GB)
Title: Improvements in the manufacture and production of sulphonation products
Filed: 1937-09-23
Abstract: Impure sulphonated products derived from alcohols or olefines containing 10 to 25 carbon atoms or mixtures thereof are freed from undesired constituents by extracting the aqueous solution of the products, after the addition of a water soluble inorganic salt with an ether having six or less carbon atoms in the molecule and boiling at a temperature below 100 DEG  C.  The extraction may be effected before or after neutralization of the sulphonated products.  The wetting and cleansing properties of the products are improved by the purification process.  Alcohol containing mixtures, which may contain fatty acids, esters, aldehydes and ketones as impurities and are suitable as starting materials for the sulphonation may be obtained by the reduction of fatty oils and waxes and free fatty acids such as oleic, linoleic, train oil, cotton seed and sunflower seed fatty acids.  Oxidation products of aliphatic hydrocarbons of high molecular weight such as paraffin oil or wax and montan wax may also be used.  In an example, an alcohol mixture obtained from oxidized scale wax, is sulphated in the presence of petroleum ether, after extraction and hydrogenation, and is neutralized with caustic soda. Trisodium phosphate is first added to maintain a constant pH value and then sodium sulphate, before extracting four times with diethylether to remove the unsulphated and unsulphatable material. The extraction may be carried out continuously, by passing the sulphated mixture containing the inorganic salt down a tower packed with balls of quartz, glass or other ceramic material, while passing the ether solvent upwards through the tower.  When sufficient inorganic salts are formed by the neutralization of the sulphonated products, further inorganic salts need not be added.  Before the sulphonation, saponifiable constituents when present may be removed. Specifications 324,189, [Class 2 (iii)], 352,537, 356,731, 407,990, and 453,134 are referred to.

Abstract: 209,142. Pilkington Bros., Ltd., and Waldron, F. B. Sept. 25, 1922. Rectilinear-motion bearings; spring supports. -In a machine for the continuous grinding of glass plates the sliding friction between the tables carrying the glass and the guides is in part replaced by rolling friction. The tables slide on guide-surfaces 2, and the rolling-friction devices, which are located at intervals along the machine, each comprise a wheel or roller 3, which may be double as shown in Fig. 2, supported in a bearing 4 fixed to a spring 5. The spring rests at one end thereof on the machine frame 1, and at the other end is pivoted to a bolt 6, the upward pressure of the wheel upon the table being varied by adjustment of the bolt. Counterweights may be employed in place of the springs, or wheels may be mounted in spring- supported journals on the table, and run on tracks adjacent to the guides. The upward pressure of the wheels on the tables may be adjusted so as to be a maximum at the starting end of the machine, whereby the pressure between the tables is more nearly equal throughout the machine.

Title: Polymerisation catalyst for vinyl chloride
IPC: C08F4/34
Filed: 1960-07-27
Abstract: A process for preparing granular vinyl chloride polymers comprises (1) agitating in a closed reaction vessel a suspension of 100 parts of vinyl chloride in 100 to 400 parts of an aqueous medium containing a suspension stabilizer, (2) introducing 0,005 to 0,100 parts of a preformed dialkyl peroxy dicarbonate and (3) heating the suspension at 100 DEG  to 160 DEG F.  The dicarbonate is preferably added to the initial monomer charge.  Di-C1-6 alkyl peroxy dicarbonates, especially diisopropyl, are preferred and, to avoid the risk of explosion, may be used as a solution in a stabilizing solvent such as xylene or toluene or with other stabilizers, e.g. cyclohexene, naphthalene, phenol or diphenyl ether.  The dicarbonate may be used in conjunction with a conventional peroxide catalyst, e.g. lauroyl peroxide, to maintain the polymerization rate towards the end of the reaction. Suspension stabilizers mentioned are gelatin, polyvinyl alcohol and water-soluble cellulose ethers.  Buffering agents and anionic or nonionic surface-active agents may be used to modify the physical properties of the products.

A ventilating system for a motor vehicle comprises a two-speed blower, the high-speed section of which can only be energized when the speed of the vehicle exceeds a predetermined value. An electrically-driven blower 15 has a low-speed section which can be energized over a switch 18 when the vehicle is stationary or when the vehicle speed is less than a predetermined value (given as 20 m.p.h.). The high-speed section of the blower 15 is energized over a switch 14 in series with a switch 12 which closes only when the vehicle exceeds 20 m.p.h. The arrangement thus ensures that the battery 10 is not overloaded and that the high-speed section of the blower is only switched in when the generator 20 is rotating at a speed sufficient to allow it to handle the load imposed on the system by the high-speed section of the blower.
