Title: Process for the hydrogenation of unsaturated fatty acids
Inventor: RUITER LUKAS HANS
IPC: C11C3/12
Filed: 1959-01-23
Abstract: Unsaturated fatty acids are catalytically hydrogenated in the vapour phase in the presence of water vapour, the hydrogenation vapour mixture containing from 2 to 200 molecules of water for each 100 molecules of hydrogen.  The hydrogenation may be partial (in which case it may be selective) or complete.  In practice the water is introduced into the hydrogenation vapour mixture before it contacts the catalyst.  Preferably from 5 to 50 molecules of water are used for each 100 molecules of hydrogen employed, the total amount of hydrogen and water being usually 20 to 200 molecules for each molecule of fatty acid.  The preferred pressure is from 600 to 2280 mm. Hg, with a partial pressure of fatty acid of 10 to 40 mm.  A temperature of above 150 DEG C. is used in practice, conveniently from 200 to 280 DEG C. when C10-24 acids are being hydrogenated. Fixed bed or fluidised catalysts may be used; nickel and alumina catalysts suitably deposited on alumina or silica may be used. Dissolved air is preferably removed from the acid before hydrogenation.  The hydrogen may be first passed through water at a temperature to give the desired water content, then through a vapouriser containing the unsaturated material at a temperature to provide the desired acid content and then over the catalyst.  In examples, oleic acid and fish oil fatty acids are hydrogenated. Specification 828,661 is referred to.

Title: Improvements in and relating to synchronous electric motor control systems
IPC: H02P1/46
Filed: 1948-01-29
Abstract: 654,763. Synchronizing A.C. machines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 29, 1948, No. 2705. Convention date, Jan. 29, 1947. [Class 38 (iv)] [Also in Group XXXVII] A system for applying D.C. excitation to the field of an induction-starting synchronous motor 1 at an appropriate moment of the running-up period comprises a field contactor 4, a discharge resistor 9 connected across the field in the deenergized condition of the contactor, a control relay 25 with delayed pick-up and release, a power factor relay 21 (which normally operates under " pull out " conditions of the motor to remove D.C. excitation) and a phase shift circuit 15, 16, 18a, 18b, the connection of which to a thyratron 14 (controlling a relay 17 having contacts in coil circuit of contactor 4) is controlled by a further relay 10, both the phase shift circuit and relay 10 being energized from the discharge resistor 9. Closure of the " start " button 6 energizes line contactor 2 to apply A.C. to the motor and energizes relay 25 which picks up, being raced, however, by relay 10 which disconnects the phase shift circuit from the thyratron which, in consequence, is held off. Contacts 25d, open to reduce the current in relay 10 to a holding value and contacts 25c close to increase current in the pressure coil 21b of power factor relay 21 which, in consequence closes its contacts 21c. The last, together with contacts 25b of the control relay (now closed) and the holding contacts 2c of the line switch 2 prepare an energizing circuit for the coil 4a of the field contactor, which circuit is now only open at contacts 17b of relay 17. As the machine nears synchronous speed relay 10 drops out, due to the low frequency of the slip current, whereby a " turn-on " voltage from the phase-shift circuit is applied over contacts 10b to the grid of the thyratron 14. Relay 17 thereupon closes its contacts 17b and completes the energizing circuit for the field contactor coil. The field is now connected to a D.C. source 5, 5a over contacts 4c, 4d, whilst contacts 4f close to byepass relay contacts 25b, and contacts 4e open to de-energize relay 25 which drops out with delay and, by the opening of its contacts 25c, re-conditions relay 21 such that its contacts 21c will open under power factor conditions indicative of the motor pulling out of synchronism. If " pull out " occurs the system attempts to re-synchronize the motor. An overload relay 8 may be provided.

Title: Improvements in or relating to signal transmission circuit arrangements
IPC: H03F3/40
Filed: 1941-02-28
Abstract: 548,968. Transmission systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1941, No. 2717. Convention date, Feb. 29, 1940. [Class 40 (iv)] In an arrangement for separating the lower frequencies (say 0-400) from the upper frequencies (say 400-10,000) in a transmission circuit 7, 8, a rough separation is effected by low and high-pass filters constituted by resistance/condensers combinations 11, 12 and13, 14 and the currents in the low-frequency circuit 5 modulate a carrier of a frequency higher than any in the transmission circuit and are then filtered to remove side-band components corresponding to the frequencies of the other channel and rectified. A voltage derived from the rectified currents is then applied by way of a filter similar to filters 13, 14 to a second grid 39 of a tube 40 in the high-frequency channel to balance out the lowfrequency components that were not stopped by the circuits 13, 14. In a modification, the equivalent of a bandpass filter cutting off at 50 and 60 cycles is obtained by the provision of two circuits like the circuit 5 the outputs of which have ranges of 0-50 and 0-60 cycles. These outputs are fed in opposition to the final circuit. By feeding this combined output in a suitable direction to another circuit from which the original ranges were derived, a band suppression effect may be obtained. Preferably the high-frequency band-pass filter is tunable.

Title: Improvements in or relating to high frequency signalling systems or apparatus
IPC: C03B23/26
Filed: 1938-01-28
Abstract: 491,196. Signalling through dielectric guides. STANDARD TELEPHONES & CABLES, Ltd. Jan. 28, 1938, No. 2808. Convention date, March 30, 1937. Addition to 468,548. [Class 40 (v)] Relates to means of the general kind described in the parent Specification for converting one type of displacement wave to another, when travelling through an evacuated or air-filled metallic tube acting as a dielectric guide. Two types of waves are particularly specified, one having a transverse electric component with transverse and longitudinal magnetic components, the other having a transverse magnetic component and both transverse and longitudinal electric components. Each type of wave has a characteristic cut-off frequency for a given diameter of the guide. The change from one wave to another is effected by the action of metal barriers, which are interposed in the path of the wave and serve as " virtual generators " of a new type of wave, which may then be combined with the incident wave. The barriers may be circular, Fig. 2A, or semicircular in shape, the latter being arranged at different angles to the axis of the guide, as shown for instance in Figs. 3A, and 3B, and Figs. 3D and 4C. Other forms of converters are shown in Figs. 6C, 7C, 8C, 9A and 9C respectively, all of which can be located at points where the diameter of the dielectric guide changes. Fig. 14 shows a back-toback or two-way converter, the various crosssections of which shown in Figs. 14A ... 14F. One type of wave may be transformed into another better adapted say to travel over a different size of dielectric guide, the wave then being changed back to a form in which it is finally utilized. Transformation may also be effected in the course of repeating signals between two different sections of a dielectric guide. Specifications 420,447, 464,185, 466,063, and 472,725 also are referred to.

Title: A process for preparing high molecular weight polymers or copolymers of alpha, beta-ehylenically unsaturated aldehydes
IPC: C08G2/00
Filed: 1963-01-23
Abstract: High-molecular weight polymers or copolymers of a -b  ethylenically unsaturated aldehydes, in the form of a finely divided substantially dry polymer are produced by effecting the polymerization or copolymerization with the acid of a redox polymerization catalyst system in the presence of a hydrocarbon. The hydrocarbons which are used in amounts of from 20-70% by weight of the total reaction mixture are preferably liquid hydrocarbons containing no more than 10 carbon atoms.  Preferably amounts of water ranging up to 50% by weight of the reaction mixture are added, in which case it is also preferred to use a conventional water-in-oil emulsifying agent. Conventional Redox catalyst systems are used in an amount of from 1-10-6-2X10-2 mols per mol of unsaturated aldehyde. The reaction is preferably conducted at a pH between 1-7 and in an inert atmosphere. The resultant polymers are insoluble in water and conventional solvents, the polymers may however be solubilised by reaction with sulphur dioxide or an alkali bisulphite.

Abstract: 193,252. Cable Accessories Co., Ltd., Reeves, F. H., and Davis, P. W. Feb. 1, 1922. Switches, quick-action.- In quick make-and-break switches of the dead-centre toggle type, collective slow movement of the whole switch mechanism when in the dead-centre position is prevented by the engagement of the free end of the toggle, connected with the contact-member, with a projection disposed in the path of its movement. As shown applied to a tumbler switch, the contact-carrying member 12 is pivoted to a fixed pivot 5 on which is separately pivoted a toggle link 6 to which is pivoted in turn the second toggle link 8 consisting of a pin, the free end of which passes through a hole in a stirrup-plate 10 pivotally mounted between the arms of the contact-carrying member. A helical spring surrounds the pin and bears upon the stirrup. The switch is actuated by a tumbler lever through a link 15 connected to the joint of the toggle. The free end of the pin engages with a cam-shaped plate 18 made with or attached to the base-plate 1 or formed upon the insulating base. The movement of the switch mechanism at the dead-centre position is arrested by the cam and continued movement of the operating-lever positively destroys the dead-centre position, ensuring a quick action.

Abstract: 745,780. Sausage, linking and twisting. CROSS, L. P. Feb. 2, 1954, No. 3046/54. Class 28(2). A continuous length of sausage 23, Fig. 11, travelling down from between rollers 71 is necked at spaced intervals by pairs of opposed forks 21, 22 which move in towards the sausage and then travel down with it and then separate, the neck being then twisted as it passes through a grooved throat 94 by the high speed rotation of a pan 83 containing the previously formed links of sausage. The twisting takes place when the lower forks 21 release their grip by separation at the same time as the upper forks 21 close in to grip and form the next neck. The rotation of the pan 83 also lays the sausages in helical formation therein by centrifugal force so that they can be removed as a coil by lowering the bottom of the pan 83 by a handle. The forks 21 are mounted on flat oppositely rotated triangular casings 19, 20, Fig. 4, with peripheries 30 which maintain contact with each other, the casings containing gearing to the forks, such gearing maintaining the horizontal grip of the forks on the sausage during the rotation of the casings to bring successive pairs of forks in turn to grip and neck the sausage length. The sausage length passes down a guide tube and is prevented from buckling by guide strips such as 80.

Filed: 1936-02-01
Abstract: 469,825. Recording finger-prints. TRIGGS, W. Wr. Feb. 1, 1936, No. 3118. [Class 100 (ii)] [Also in Groups XIX and XVIII] Coin-freed mechanism in which the insertion of a coin uncovers an opening in the machine so as to permit the introduction of the operator's finger for obtaining his finger-print and for operating mechanism for issuing an insurance ticket or receipt or the like, is characterized by means which, on pressure of the operator's finger, sets in operation a finger-print recording device 14 and ticketissuing means. When a coin is dropped into slot 1 or 2 it rocks a lever 4 counter-clockwise, Fig. 3, so that its end 4<1> releases the end 51 of a lever 5 pivoted at 62 whereby slide 6 is lowered and its hole 7 registers with a hole 9 in the casing. The operator's finger may then be inserted to press a button 10 and slide 11 to the left. A bolt 12 or slide 11 moves lever 13 to release a hammer 14 which is raised by a spring 15 to record a finger - print on the ribbon 18. Subsequently a blade 57 cuts off this portion of ribbon 18, which is retained in the machine. Immediately after the finger-printing a contact 19 on arm 14 meets a contact 19<1> to energize a motor 20 which rotates a shaft 22 operating a shaft 24 and the blade 57. Shaft 24 drives (1) train 50, 51, 52, 53 and wheel 54 to feed the finger -print strip 18 from roll 55 and (2) train 25, 26, 27 to feed from roll 29 a strip 28 serving as tickets for insurance or receipt. Strip 28 is thus feed along channel 30 until it reaches engraved wheels 33 driven by the clock 31. 34 Is an inking ribbon. A hammer 32 is periodically operated to strike the paper into contact with the wheels 33 thereby printing the year, month, day, hour, and minute. An eccentric' 36 on shaft 22 thus actuates blade 35 to cut off the ticket from roll 28, which falls through channel 37 to delivery trough 38. Before the end of strip 28 reaches the wheels 33, slots on strip 28 allow a roller 45 to rise : this roller is on the end of a lever 46 pivoted at 47 so that a member 48 is lowered to close the coin slots 1 and 2. Parts 6, 11 and 14 are restored and relatched through cams 60 and 65 on shaft 22.
