Patent GB-903978-A (GB)
Title: Manufacture of surface-active compositions
IPC: C11D1/22
Filed: 1960-10-13
Abstract: Non-gelling water-soluble detergent compositions are obtained by neutralizing with an amine the sulphonic acid obtained by sulphonating an alkylaryl hydrocarbon with sulphur trioxide, and subsequently adding thereto a minor quantity of an amine sulphate. Suitable amines which may be used both to neutralize the sulphonic acid and in the amine sulphate are mono-, di-, and tri-ethanolamine; mono- and tri-ethylamine; mixed isopropanolamines; and n-butylamine. The composition is generally compounded as an aqueous composition, and usually contains amine sulphate in an amount of about 5 - 15% by weight of the sulphonic acid to be neutralized.ALSO:Triethanolamine dodecylbenzene sulphonate is obtained (see Examples 1-3) by neutralising with triethanolamine the acid obtained by sulphonating dodecylbenzene with sulphur trioxide, sulphuric acid or oleum; if excess sulphonating agent is used, the amine sulphonate formed on neutralisation prevents the mixture gelling (see Group III).

Title: Electric circuit module
IPC: H01L23/485
Filed: 1970-07-22
Abstract: 1298115 Electric couplings INTERNATIONAL BUSINESS MACHINES CORP 22 July 1970 [14 Aug 1969] 35468/70 Heading H2E [Also in Division H1] A plurality of metal bonding pads disposed around the periphery of one face of an integrated circuit chip are mechanically attached to corresponding metal regions on a substrate by electrically conductive spacing connections not all of which have the same shear resistance. Differences in shear resistance are achieved by using different materials in different connections, e.g. by using copper balls in some while others consist entirely of solder, by using similar amounts of solder at all joints in association with different sized wettable areas on the substrate regions and/or bonding pads, by using different amounts of solder with identical wettable areas or any combination of these techniques. Where all connections serve as electrical circuit connections stronger joints are used at points of maximum thermal stress and 'vice versa but if some joints have only a spacing and mechanical function they may be weakest and located at points of maximum stress. Wettable areas may be limited by glass barriers crossing the metal region or by coating certain areas with non-wettable metal.

Title: Improvements in or relating to the manufacture of margarine and edible fats
IPC: A23D7/005
Filed: 1920-12-17
Abstract: In the manufacture of edible fats especially margarine from vegetables &c. fats an oleanginous material having "water-dispersing properties" is added to the usual ingredients, or to the fats after manufacture, so that an emulsion is formed having the aqueous liquid as the internal phase in a state of very fine subdivision.  The water-dispersing medium may be prepared as described in Specification 187,299.  For example, soya-bean, oil may be heated and air passed therethrough until gelatination sets in, and oils, such as cotton-seed, ground-nut, or sesame oil are stirred in.  The watery constituent of the emulsion may consist of water or milk, and sugar, glucose, or other fermentable substances, which may contain vitamines, and salts may be added.  The fermentation of such substances is checked by the film of the water-dispersing medium surrounding the aqueous globules.  The emulsion may be dissolved in a suitable fat or oil, before adding to the margarine &c.  The water-dispersing medium may be added direct to the cocoanut oil or other fat from which the margarine &c. is to be made, or part of the medium may be so added and part added in the form of an emulsion.

Abstract: 759,054. Wire strainers. STRAPPINGS, Ltd., and CROUCHER, Ltd., A. H. Dec. 23, 1954 [Dec. 24, 1953], No. 35883/53. Class 45. [Also in Group XVII] Wire or strip is fed into a banding machine through a guide 28 and passed about a grooved wheel B20, through a slotted pinion, (see Fig. 3, not shown), and a stationary guide ring 32 surrounding the package, the end of the wire being again passed through the pinion prior to entering a stationary gripper. The shaft 9 of the machine is driven by an electric motor (see Fig. 2, not shown), through a belt and pulley drive incorporating a friction clutch 15, 16. The shaft 9 has a worm 21 machined thereon which drives the worm-wheel of a unit having a number of cams. The pinion is controlled by the cam A and is initially rotated to over twist the wire and then reversed a small amount to free the wire in the slot. The wheel B20 is driven by the cam B through a telescopic hydraulic link and suitable gearing B1 ... B40 (see also Figs. 3, 4, 5 and 7, not shown), the arrangement being such that on the push stroke of the link the wire is pulled about the package whereupon the link telescopes and the wheel B20 stops. Cam C controls the right-hand gripping mechanism through means C1 ... C7 (see also Fig. 6, not shown). The movable gripper is initially moved to secure the wire against an anvil and then moved therewith to the right to effect tensioning. Cam D operates the left-hand gripper and the removal of the cover D9, Fig. 4 (not shown), from the track along which the wire is fed through the twister pinion, control being effected through appropriate linkage. A further cam operates the ejectors for removing the knot from the twister pinion whilst another cam operates loading fingers and cutters, the ejectors, fingers and cutters being duplicated on either side of the twister pinion. Finally, a trip cam actuates the clutch rod 18 to stop the machine, a rod G6 controlled by a foot pedal being arranged to lift the roller G5 out of the way and the clutch to re-engage. Means may be provided for disengaging the pressure wheel 29 from the grooved wheel B20 whilst the latter is returning to its commencing position. The guide ring 32 may be made of different shapes and sizes according to the packages to be catered for: Two such machines may be mounted together with their rings on a common axis so that two buildings may be made simultaneously in which case the machine cycles are synchronized so that they may be operated by one electric motor. Specification 615,657 is referred to.

Title: Improvements relating to apparatus for continuous testing of materials
Inventor: FIELDEN JOHN ERNEST
IPC: B65H63/06
Filed: 1953-12-30
Abstract: 772,049. Statistical measurements. FIELDEN ELECTRONICS, Ltd. Dec. 14, 1954 [Dec. 30, 1953], No. 36158/53. Class 37. In a system for determining percentage mean deviation of a parameter, voltages representing respectively the value of the parameter and the fluctuations in one direction of that value are integrated over the same period of time and control meters. In the system described, textile yarns, slivers or rovings are driven during the period of a cycle between the plates of a capacitor 1 forming part of a bridge circuit 2 supplied with modulated high-frequency current by a device 3. The output of the bridge is amplified and rectified at 4, 5 and the fluctuating low-frequency signal after further amplification at 6 is rectified at 7 and filtered to give a unidirectional voltage across R16 which varies in accordance with the instantaneous mass per unit length of the yarn between the capacitor plates 1. An adjustable fraction of this voltage is applied to a Miller capacitor C32, V8 and controls the deflection of a meter in the anode circuit of V8. The same voltage after the removal of the steady component and the fluctuations in one direction by capacitor C31 and rectifier 8 is applied to a similar Miller circuit associated with a meter M2. M1 thus shows the mean value of mass per unit length and M2 the mean deviation. The cycle is determined by constantly driven cams which connect the Miller capacitors alternately to the charging and to discharging circuits. A further cam ensures the completion of a cycle after the initiating switch 19 has been released. A switch S2 enables M1 to receive directly the rectified output of amplifier 6 for zero setting. A switch S3 cuts alternative resistors into circuit with M2 for range changing.
