Title: Improvements in and relating to the stabilisation of organic compounds
Inventor: COWIE CHARLES THOMSON YOUNG
IPC: C07C45/86
Filed: 1950-05-25
Abstract: Organic compounds liable to deterioration by peroxide formation are stabilized with small amounts of diaminodurene, or an alkylated or acylated diaminodurene.  Compounds mentioned are liquid aldehydes, ethers, and esters of unsaturated carboxylic acids.  Preferably 0.001 to 1 per cent of additive is present. Diamino durene is preferred. Other durenes mentioned and the preparation of which is detailed are N,N1-tetramethyl-, N,N1-diisopropyl- and N-ethyl-N1-acetyl-diamino durene, the last two compounds being new.  Diamino durene is made by nitrating durene and reducing the product and the N,N1-tetramethyl- and -diisopropyl-derivatives respectively by treating diamino-durene with methyl iodide under alkaline conditions and by reacting dinitro or diamino durene with acetone in the presence of hydrogen preferably at elevated temperature, e.g. 50-100 DEG  C., and pressure, e.g. 20-50 atmos., and with a hydrogenation catalyst, e.g. platinum-on-charcoal. N-Ethyl-N1-acetyl diamino durene is made by acetylating durene and partially reducing the diacetyl compound thus formed with, e.g. lithium aluminium hydride, preferably in a solvent, e.g. tetrahydrofuran, at elevated temperature.  In examples: (1) nonaldehyde, (2) tetrahydrofurfuryl alcohol, and (4) methyl esters of linseed oil are stabilized with diamino durene, other stabilizers are N,N1-tetramethyl-and N-ethyl-N1-acetyl-diamono-durene in (1) and N,N1-di-isopropyl-diamino-durene in (2).  According to the Provisional Specification fatty, vegetable and lubricating oils may also be stabilized.ALSO:Petrol is stabilized by the addition of a small amount of diaminodurene or an alkylated or acylated derivative thereof. Preferably 0.001 to 1 per cent of additive is used. Diaminodurene is preferred, other durenes specified being N, N1-tetramethyl-, N, N1-diisopropyl- and N-ethyl-N1-acetyldiamino durene.  In Example 3 thermally cracked petrol is stabilized with 0.04 per cent of diaminodurene.

Title: Toy banks
IPC: A45C1/12
Filed: 1945-05-26
Abstract: 592,726. Toy money-boxes. MUNROE, J. A. May 26, 1945, No. 13226. Convention date, May 30, 1944. [Class 132 (iii)] [Also in Group XVII] A toy money-box comprises a hollow case representing a grotesque animal with body, head and tail, the head and tail being each pivoted, the head carrying a device for holding a coin edgewise, the tail being connected to a spring- urged device by which movement of the tail is utilized to flick the head upwards about its pivotal axis and to toss the coin into a slot in the body of the animal. The coin receiving slot is provided with a pivotal closure so that it opens concurrently with the movement of the head. The spring-urged device comprises a bar extending from the tail, the end opposite to the tail being engaged loosely in a hole or aperture in the rear portion of the head, and a spring mounted on the bar so that pressure is applied on the head causing it to be flicked upward by a movement of the tail. Figs. 1 and 2 show the toy in the form of a grotesque elephant. The body 10 of the elephant is hollow and supplies a receptacle 11 for coins. For convenience in construction the body is made in two parts with a junction provided with an inner flange and held together by screws 13. The head 15 is pivoted about its centre 17, its movement being constrained by stops 18a so that the effect of a tossing head is produced. The trunk 18 is upturned and carries a device 19 to seat a coin 20 edgewise, so that an upward flick of the head will toss the coin into a slot 21 (Fig. 2) normally closed by a pivoted lid 22. This lid has an arm 23 connected by a flexible element 24 to the head. The coil 16 is pivoted at 25 and is extended inwardly by a bar 26 passing through an aperture 27 in the head. A coil spring 28 is sleeved on the bar and shouldered at the tail end thereof. By this means an upward movement of the tail causes an upward toss of the head with simultaneous opening of the slot to receive the coin.

Abstract: 1,146,698. Trimming tankers. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 25 March, 1966 [30 March, 1965], No. 13247/66. Headings B7A and B7M. [Also in Division G3] A controller for determining the sequence in which the compartments of a tanker are coupled to a pumping system during loading or unloading to assist maintenance of a constant list attitude, is overridden by a device responsive to the list attitude to ensure that the latter is maintained constant. In Fig. 2, outer compartments 18-27 of a tanker are filled or emptied through piping 29 by a pump 30, and the particular compartments being filled or emptied at any time being selected by the setting of valves 40 in intake pipes near the rear baulkheads of each compartment. The sequence of operation of the valves is controlled by a programmer (not shown) so that the ship achieves and maintains a constant angle of list during the operation. List detectors, operating by measurement of level in the compartments, are provided so that the programmer is overridden when necessary to ensure that the angle of list is in fact maintained constant. A separate pump 37 communicates with the after one of a number of central compartments 31-35 and valves 36 between these compartments are so controlled by the programmer that the ship is maintained stern-heavy with a constant longitudinal angle of trim. If necessary to correct large deviations of list, pump 37 is utilized to assist pump 30. In addition to pumps 30 and 37, which are of the high-speed centrifugal type, slow-speed piston pumps having a separate pipeline system (not shown) are provided to operate below predetermined levels. When emptying a compartment, approach of the predetermined level is detected by the increase of pump speed, whereupon the valve associated with that compartment is partially closed and that associated with the next compartment partially opened to maintain constant delivery until the predetermined level is reached and the piston pumps brought into operation. During filling, the supply to each compartment is terminated by change in pressure resulting from the level reaching an air pressure supply orifice. Closing of the valves after filling may automatically connect a separate pipeline system in readiness for emptying. Stresses in the hull of the ship are also detected and, if excessive, automatically reduced by overriding the list control and widening the limits of permissive list angle.

[Also in Division G1] Apparatus for producing an electric signal D representing the square root of the product of two input signals A, B comprises an operational amplifier I with feedback to the input through capacitance C1 with voltage A applied to the input over resistance R1 and a capacitance C2 alternately charged by switch 3 from the output signal D and connected to the input of amplifier 1 in such sense that C1 is then discharged; a breakdown device 2 connected to the output of 1 to operate when the voltage across the capacitor C2 reaches a given value; a second operational amplifier 5 with feedback to the input through parallel capacitance C3 and resistance R2 from output D; a capacitance C, alternately charged by switch 4 from signal B and connected to the input of amplifier 5; and means operated by the breakdown device to operate switches 3, 4 at a frequency f of operation of the breakdown device; it being shown that The breakdown device may comprise a gas discharge tube arc bi-stable transistor circuit operating relays, and capacitor C2 may be replaced by two capacitors alternately charged from D and discharged into C1 by two switches operated at frequency 8 from breakdown device 2 in antiphase. Device 2 may be capacitance shunted and operated through a blocking diode. The square root of a quotient may be determined by transforming the diviser into its inverse. The output signal D may be low-pass filtered and may be integrated by conversion into a pulsed signal of frequency proportional to its instantaneous value, which then operates a counter. Signals A, B may be respectively derived from the pressure drop across the aperture of an orifice plate in a pipeline and from the density of the fluid therein, when D represents the mass flow and may be integrated to measure quantity passing (Fig. 2, not shown).

Abstract: 1,056,063. Lighting buildings; daylight diffusers. COMPONENT COORDINATION Ltd. July 5, 1963 [April 16, 1962], No. 13413/ 63. Headings E1A and E1J. A building 2, 4 has a planar diffuser 1, e.g. constituted by two glass sheets with a layer of glass fibres therebetween, inclined to the vertical with its lower edge relative to its upper edge lying inwardly of the building. The angle of inclination is such that the flux of solar light is strongest in a desired direction. This is possible because the spatial light distribution of the light emerging from the diffusor has a maximum (or maximer) in a direction(s) which varies with the angle of incidence and this latter angle is chosen so that the maximum direction of the emergent light is directed toward the ceiling, so that at midday the light diffused directly into the room is less them at other times and the light directed toward the ceiling is strongest. The diffusor may be incorporated into a window assembly 1, 13 which has opening window components 9, 16 and the diffusor 1 itself may partake of a sliding movement to open or close the window containing it. The windows 1 and 13 may lie in the same inclined plane.

Abstract: 456,354. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., 9, Kingsway, London.-(Assignees of Mergenthaler Setzmaschinen-Fabrik Ges.; 25, Chausseestrasse, Berlin) May 8, 1935, Nos. 13531 and 13532. Convention dates, May 18, 1934. [Class 100 (iii)] In a type-bar-making machine having a rotatable mould disc and a relatively stationary vice frame in which matrices are supported in casting relation to a mould carried by the disc, there is provided a carrier permanently mounted on the vice frame and adapted to sustain a matrix holder or hand stick for presenting to the mould a line of matrices composed by hand in the holder or handstick. The carrier is supported by the vice frame 3 and comprises a fixed member 5 attached to the vice frame by bolts 7 and a movable member 6 in which the composing stick 21 may be removably supported ; alternatively, the stick 21 may form a part of the carrier and the matrices may be inserted directly therein by hand. To bring the matrices 22 into register with the slot in the mould 1, the movable member 6 which engages by a tongue-and-groove connection with the member 5 is adjusted by rotating an arm 13 which turns a pinion 10 in engagement with a rack 9 on the member 6 and the arm is locked in adjusted position by a spring plunger 18 which engages in one of a number of recesses on a plate 20 fixed to the vice frame. The matrices are locked in the composing stick 21 by the screw-operated jaw and the stick is held in position by projections 25 thereon which engage with blocks 26 on the member 6, a lug 28, Fig. 6, on the stick and an abutment 27 securing it against lateral movement, while vertical movement is prevented by means of a mutilated collar 30 which is adjusted by a screw 29. The collar carries a pin 31 which limits the movement of the collar and in one position it permits the stick to be inserted after which it is rotated to the position shown in Fig. 4 wherein it holds the stick against vertical movement. In addition, the collar has a spiral groove which is engaged by a pin 34 on the stick, so that upon rotating the collar the stick is held firmly against the member 6. In the machine described, the vice jaws are omitted and the pump-stop mechanism is operated upon the insertion of the hand stick or of the matrices into the carrier by providing in the member 6 a spring-pressed plunger 35 which in its projected position permits a spring- pressed rod 37 to engage a recess in the plunger 35, this determining the limit of the movement of the rod 37 to the right. Upon inserting the hand stick or matrices, the plunger 35 is depressed and moves the rod 37 to the left ; this rod engages with the pump stop lever, which is moved thereby to its inactive position. In a modification, the member 6 may be omitted and the hand stick may be itself provided with set-screws or other adjustable stops to support the stick at the desired level on the carrier.

Title: Improvements in or relating to shaped resilient articles
IPC: C08L1/00
Filed: 1943-08-25
Abstract: 574,575. Agglutinated fibrous materials. WOODMAN, T. C. Aug. 25, 1943, No. 13593/42. [Class 140] [Also in Groups IX and XXV] A resilient article for use in place of rubber is made by dipping a shaped body of fibres matted together to an average density of 0.2-0.4 grams per c.c. in a dope containing a flexible film-forming material other than cellulose acetate, removing the body when it contains 10-25 per cent. of film forming material based on the weight of the fibres and while the penetration of the dope is still incomplete, and drying without subjecting to heat and pressure. The film forming material may form a skin on the surface of the body and leave the centre or core unimpregnated. The impregnation may be effected in a chamber which is evacuated before the dope is run in and later subjected to pressure to force the dope into the body. The dried impregnated body may be re-dipped once or oftener. The shaped body may comprise animal fibres, e.g., wool, artificial filaments or fibres, or both. The dope may be a solution in a volatile solvent of a cellulose derivative, e.g., cellulose propionate, butyrate, acetate-propionate, acetatebutyrate, acetate-stearate, ethyl, benzyl, or hexyl cellulose, polyvinyl compounds, e.g., polyvinyl acetate, a copolymer of vinyl chloride and acetate, or a polyacrylic ester or an aqueous suspension or latex containing plasticized ethyl cellulose, polvinyl chloride, poly-vinylidene chloride, polyisobutylene, polymers of butadiene or chloroprene alone or together with styrene, acrylonitrilo, or isobutylene. or rubber and its derivatives. A plasticizer, e.g., castor oil or tricresyl phosphate may be added. Dyes, pigments, abrasive materials, solid lubricants, e.g., graphite or talc, or fire retardants may be added to the dope or incorporated in the fibrous body before impregnating. The products are suitable for shock-, vibration-, or pressure-absorbing stops, buffers, or mountings, e.g., door stops, buffer pads for water closet seats, buffers in textile looms to check the motion of the picking sticks or as the shock absorbing pads mounted on frogs at either side of the loom, or as coverings for the cloth-engaging parts of the loom temples, in which case the continuous outer skin may be skimmed off to give better friction.
