Filed: 1963-09-13
Abstract: 1,019,483. Automatic voltage control. ROTAX Ltd. Aug. 11, 1964 [Sept. 13, 1963], No. 36134/63. Heading G3R. A voltage regulator for an alternator includes means for reducing the alternator field current when a control signal, which varies with the square of the alternator output voltage, exceeds a predetermined value. As shown, the field 33 of an alternator 5 is energized from a D.C. source (not illustrated by way of an amplifier 31. A D.C. voltage proportional to the alternator output voltage is derived from a transformer 8 and rectifier 12, 14, 15, 16 and is applied to lines 11 and 13 which are interconnected through resistors 17, 18,19 and 20 associated with Zener diodes 22, 23, 24 connected to line 11 as shown. In use, as the voltage between lines 11,13 rises, the Zener diodes 22, 23, 24 break down successively to maintain constant the voltages across resistors 17, 18, 19, the values of the components being so chosen that the voltage signal across resistor 20 approximates to the square of the alternator output voltage. This voltage signal is applied by way of an integrating circuit 25, 27 to the base of a transistor 26 having its emitter connected to line 13 over a reference Zener diode 28 and its collector connected to the amplifier 31. When the voltage across capacitor 27 exceeds a value determined by the breakdown voltage of Zener diode 28, transistor 26 conducts and causes the amplifier 31 to reduce the field current.

Title: Improvements on high bulkiness for textile products
Inventor: HITOMI KEIICHI
IPC: D02G1/18
Filed: 1961-10-16
Abstract: Each man-made e.g. cellulose diacetate or triacetate, polyacrylic, polyester, polyolefin, polyvinyl alcohol, or natural fibre or filament of fibrous material e.g. sliver, tow, tap, yarn, which may be used to make high bulk yarns or fabrics, comprises in an axial direction alternate H and L portions, H having the capacity of shrinkage to a greater extent than L when subjected to relaxation treatment after incorporation into a single, plied, or cored yarn or woven or knitted fabric or a "non-woven" fabric (which may be consolidated as by an acrylic emulsion binder) so that portions L are bulked out by shrinkage of H portions.  Both ends of a fibre may be H or L portions.  The lengths and proportions of the respective portions may be similar or different at random and/or in a varying and/or repeating pattern with consequent variations in appearance, bulk, elastic recovery, elongation, and/or tenacity: features such as denier and fibre length may also vary.  Different forms of the fibre or filament may be blended e.g. at the spinning or a web mixing stage and fibres such as wool of low or negligible shrinkage capacity may be included to produce an outer sheath on the yarn.  The fibre &c. is subjected to a two-stage treatment viz. preparation as by partial relaxation (under tension or "non-tension") or stretching accompanied by heating, and a secondary heating treatment in the yarn or fabric. Dry or wet heat may be employed and may be replaced at one or both stages by gaseous or liquid solvent treatment, dielectric heating, or treatment by a radioactive substance.  In the preparation, the material is gripped mechanically at a number of spaced portions therealong which are thereby insulated from the influence of the heating &c. medium.  After such preparation, continuous filaments may be randomly looped, by subjection to compressed air jets, and/or stapled.  In a machine for preparing the fibrous material, continuously moving, adjustably spaced, chaindriven grippers successively engage the material at several separate portions therealong and the free portions thereof are heated by ducted hot and/or moist air or steam as they are maintained in slack or stretched condition by the adjustable overfeed or underfeed effect of the grippers, Figs. 17-32 (not shown).

Abstract: 451,105. Motor-vehicle driving-gear. M.G. CAR CO., Ltd., and CHARLES, H. N., Pavlova Works, Abingdon-on-Thames. Dec. 29, 1934, No. 37257. [Class 79 (ii)] [See also Group XXXII] A driving road wheel is connected to the chassis frame 12 by upper and lower transverse links 13, 14, and is driven by a short shaft 18 having universal joints 17, 19 at its ends, the lengths and disposition of the links and the shaft being such as to constrain the outer universal joint 17 to move in a circular arc about the centre of the inner joint 19. The shaft 18 thus need not be telescopic. In the construction shown in Fig. 1, the links 13, 14 and the shaft 18 are all equal and parallel. The wheel-driving spindle 16 is supported in bearings in a member 15 connected to the links. The movement of the links is damped by a shock-absorber (not shown), connected to an arm 26 fixed to the lower link 14 and is limited by stops 24, 25 on the member 15 adapted to engage pins or bolts 22, 23 on the link 14. The links may be of skeleton triangular form in plan. In the construction shown in Fig. 3, the links 13<a>, 14<a> are neither equal nor parallel but are still so arranged that the universal joint 17 swings in a substantially circular arc about the inner joint at 19.

Abstract: 768,962. Fish heading and cleaning. BAADER, R. G. T. Dec. 23, 1955 [Dec. 31, 1954], No. 37841/54. Addition to 746,610. Class 28(2) In a machine in which a fish, which has been laid in each of the transverse troughs 25 of conveyer chains whereby they have been conveyed against head cutting off discs as in the parent Specification which also includes a pusher which enters the belly and pushes the fish tail first to tail grippers on a conveying wheel which conveys the fish past slitting and gut extracting tools, the belly pusher is now replaced by a pusher 84 which pushes on the cut off end at the neck. A fish is pressed firmly in its trough 25 by a flap 81 bearing against the belly. A reciprocated sliding carriage 46 moving towards the bracket 43 carries with it a sleeve 53 on which is carried the pusher 84, so that when pin 85 clears a nose 79, a spring 26 pulls the pusher 84 (pivoting on 83) against the neck end of the fish. Meanwhile the flap 81 is retained pressing against the belly of the fish by the spring 59. Thereby the reciprocated sleeve 53 moving towards 43 carries with it the flap 81 and the pusher 84 so that the fish is slid along the trough 25 until its tail enters a slot between parts 89 the slot depth stopping the fish at a thicker part of the tail which thus protrudes sufficiently to be gripped by the grippers of the parent Specification. When the fish tail is stopped in the slot the pusher 84 yields to ride over the neck and slide along the side of the fish.

Title: Process and apparatus for effluent refrigeration of an alkylation operation
IPC: C07C2/62
Filed: 1956-12-12
Abstract: In a process for alkylating isobutane by reacting a molar excess of isobutane with an olefine in the liquid phase in the presence of a liquid alkylation catalyst, the reaction product is separated into a liquid catalyst phase and a liquid hydrocarbon phase which latter is flashed to obtain chilled vapour and liquid which are passed in admixture as the sole coolant in indirect heat exchange with the reaction mixture in the alkylation zone and separating the resulting vapour and liquid phases.  Catalysts specified are 88-94% sulphuric acid and aluminium chloride-hydrocarbon complex, and the catalyst to hydrocarbon volume ratio is maintained at about 1 : 1.  The molar ratio of isobutane to olefine is between 1 : 1 and 10 : 1 and reaction conditions are 45-60 DEG  F. and about 35 p.s.i.g.  The pressure of the hydrocarbon effluent after separation from catalyst is reduced to 0-5 p.s.i.g. which reduces the temperature to 28-30 DEG F.  Where the reactor is of the internal recirculation type, the p chilled effluent is passed through conventional coils or tube bundles disposed therein; if the reactor is of the pump and time-tank type, the heat exchange means is usually encased in a vessel forming a portion of the reactor system.  The vapour-liquid separating means is preferably disposed at a height not above and preferably below the heat exchange means, so that the liquid and vapour effluent from the heat exchange means can be withdrawn in the absence of any positive static head which might cause a rise in temperature.  An example is given of the alkylation of isobutane with a butane-butylene feed, a C4 cracking gas fraction in the presence of about 90% sulphuric acid. Specification 803,481 is referred to.
