Abstract: The invention comprises acetals of the general formula <FORM:1025046/C2/1> in which R1 represents an hydrocarbon group which may contain oxygen, R2 represents a C1-C8 alkyl group or R1 and R2 together with the carbon atom to which they are attached represent a divalent carbocyclic group, R3 represents a hydrogen atom or a C1-C3 alkyl group, R4 represents a hydrogen atom or a C1-C8 hydrocarbon group and the symbols R5 each represent an alkyl or alkenyl group or together represent an alkylene group. R1 is preferably an alkyl or alkenyl group, e.g. a group of formula CH3-[C(CH3) = CHCH2CH2]n-or CH3-[CH(CH3)CH2CH2CH2]n-in which n is 1-3, and may be substituted by free, esterified or etherified hydroxy groups, a oxo group or a free or esterified carboxyl group. It may also be an aromatic or an aliphatic group optionally substituted by one of the oxygen-containing groups referred to above.  R4 may be any alkyl, cycloalkyl, aryl or aralkyl group containing 1-8 carbon atoms.  When R1 and R2 form part of a carbocyclic group the group may be, for example, cyclopentylidene or cyclohexylidene. The unsaturated acetals are prepared by acetalizing a g ,8-unsaturated aldehyde of formula <FORM:1025046/C2/2> with an alkanol, alkenol or an alkylene glycol. The acetalization is carried out in known manner by the use of acid catalysts, e.g. anhydrous mineral acids, p-toluene sulphonic acid; or a cation exchanger such as phenol-resin sulphonic acids, by the use of salts such as ammonium chloride, zinc chloride, pyridine hydrochloride, sodium hydrogen sulphate or ferric chloride or by the use of boron trifluoride etherate, the water formed during the reaction being removed by azeotropic distillation or by the addition of a water-binding agent.

Title: Method of making tapered bearing separators and the like
IPC: F16C33/54
Filed: 1967-10-31
Abstract: 1,206,476. Making tapered bearing cages; corrugating; welding by pressure. TORRING- TON MFG. CO. 31 Oct., 1967 [21 April, 1967], No. 49410/67. Headings B3A, B3E and B3R. [Also in Division F2] A method of making tapered bearing separators comprises providing cylindrical separators having a circumaxially spaced series of slots 12a separated by bars 14a and with opposite end portions comprising peripherally extending bands which include welded contiguous ends, and diametrically reducing one end portion of each separator by displacing free interbar sections 78 in a generally radial direction and out of the surface of revolution defined by the separator. Metal strip is fed intermittently and the slots 12a are blanked by tools 62 and lateral bend lines 65 are formed by tools 64. The lengths for individual separators are cut off by a tool 32a which also forms notches in the strip edges. The cropped blank is then formed by tools 38a, 39a, 40a, 41a, which co-operate with a tapered segmented portion 69 of a mandrel. The shaped blank is moved forwardly along the mandrel where it is welded between a pair of electrodes, the weld material filling the notches in the edges. A rod 7 controls expansion and contraction of the mandrel, so that it is expanded during forming and welding and contracted during the forward movement of the blank and subsequent ejection thereof. In an alternative method, the cropped blank is first formed to a cylindrical form, welded and finally formed to the required taper, Fig. 18 (not shown). In forming the taper by either method, the larger diameter may be increased, resulting in a reduction in thickness of the strip edge between the axial bars.

Filed: 1963-12-20
Abstract: 1,040,600. Preserving meat: pickling compositions. GRIFFITH LABORATORIES Ltd. Dec. 20, 1963 [Dec. 21, 1962; Dec. 12, 1963], No. 50446/63. Heading A2D. In the curing of meat such as hams, substantially simultaneously with the introduction of an aqueous solution including an auxiliary compound used with a curing salt solution, there is introduced into the meat another aqueous solution containing alkaline material incompatible with the auxiliary compound, the amount of alkaline material being sufficient to neutralize at least some of the lactic acid in the meat and to elevate the pH of the meat toward 7, thereby minimising purging of the meat in cooking. The two solutions may be combined in the conduit of an injection needle and may enter the meat as a single stream composed of successive but alternating and proportioned increments of the two solutions. Thus, one solution may contain sugar, sodium chloride, alkali-metal nitrite and nitrate, and sodium ascorbate or sodium erythorbate for stabilizing the colour of the cured meat (the ascorbate and erythorbate are incompatible with strong alkali), the other solution the alkaline material referred to. Although the alkaline material may consist of an hydroxide and/or a normal carbonate (bicarbonates are also mentioned in another context) of sodium and/or potassium it is preferred for the purposes of analysis that the selected alkali material should have only potassium cations and that the remainder of the cations of the two solutions be other than potassium ions. Phosphates (specified) may be included in the curing liquor, though the use of the alkaline material renders them largely unnecessary; trisodium phosphate and tripotassium phosphate, when employed, should be included in the solution not containing the auxiliary compounds.
