Title: Acetylene transition metal carbonyl derivatives
Inventor: HUEBEL KARL WALTER
IPC: C23C16/16
Filed: 1957-01-18
Abstract: The invention comprises the product of reacting under neutral non-aqueous conditions a transition metal carbonyl or a derivative thereof with an acetylene compound the product having the formula <FORM:0885514/IV (b)/1> where M is a transition metal, N is a carbonyl group or a substituted carbonyl group, R1 and R11 each represent hydrogen or an organic group or substituted derivatives thereof or an organo substituted hydride group, C2 represents direct carbon to carbon bonding, x is an integer from 1 to 3, y is an integer from 2 to 12 and z is an integer from 1 to 5.  M may be iron, znickel, ruthenium, rhodium, palladium, osmium iridium, manganese, rhenium, chromium, molybdenum or tungsten.  The triple bond in the acetylene compound is converted into a double or single bond.  If desired, the transition metal carbonyl may be prepared in situ from the metal and carbon monoxide; alternatively, a metal salt and a reducing agent may be used.  The acetylene compound may be substituted by an organic group such as an alkyl, alkenyl, alkynyl, cycloaliphatic, aryl or alkylaryl group or a functional group such as -COH, -CN, -halogen, -OH, -NR2, -COOR wherein R is hydrogen, an aliphatic or aromatic radical or a hydrocarbon group substituted by such a functional group.  The products may be separated by chromatography or by fractional crystallisation.  From 2.5 to 6.0 moles of acetylenic compound may be used per mol of metal carbonyl. The temperature of reaction varies from room temperature up to 300 DEG C. If desired, the carbonyl groups on the metal may be partially substituted by radicals such as nitrosyl, substituted isonitrile, substituted phosphines, substituted arsines, substituted stibines and their halides and fully substituted aromatic systems.  Complicated ring systems may be formed by heating the compounds of the invention, thus 1,3,5-triphenylbenzene is obtained by heating Fe2(CO)6(C6H5.C2H)3 or Fe(CO)4(C6H5.C2H)3 to about 170 DEG C. Heating Fe(CO)4(C6H5.C2.C6H5)2 to about 200 DEG C. yields tetraphenylcyclopentadienone, and heating Fe(CO)2(CH3OOC.C2.COOCH3)3 to 180 DEG C. yields the hexamethyl ester of mellitic acid.ALSO:Complexes obtained by heating a transition metal carbonyl and an acetylenic compound (see Group IV(b)) may be decomposed thermally to produce metal mirrors and films.  Thus glass cloth may be coated with iron by heating the cloth in a sealed tube containing Fe2(CO)6-(C6H5.C2.C6H5) 2.

IPC: H04L21/02
Filed: 1930-01-22
Abstract: 347,134. Typeprinting telegraphs. STANDARD TELEPHONES & CABLES, Ltd., Columbia a House, Aldwych, London.-( Western Electric Co., Inc.; 195, Broadway, New York, U.S.A.) Jan. 22, 1930, No. 2225. [Class 40 (iii).] Characters are converted into five-impulse code by means operated in accordance with the optical exploration of chosen areas of the character. Selected sub-areas 1.. 5 of the area occupied by each character printed on a tape P are inspected in succession by light rays passing through holes 1 .. 5 in a rotating disc D and a fixed plate PL When the character covers the sub-area inspected, the light reflected to a photo-electric cell PC decreases and the output from a thermionic amplifier A2. is sufficiently increased to operate a relay R, which connects a battery to a distributer arm D1 rotated with the exploring-disc. The distributer arm D1 contacts with a segment S1 .. S5, corresponding to the sub-area which is being inspected, and thus operates the appropriate relay R1 .. R5 and selecting-magnet SM1 .. SM5. The characters are so designed that each covers a different combination of sub-areas (Fig. 4, not shown) and thus each sets up a different combination of selecting- magnets. The relays are looked through a synchronous distributer D2, which reaches an open space to release the relays when all the areas have been inspected. Operation of any of the relays R1 .. R5 operates a relay R1 to break the circuit from a segment SS, otherwise, when a synchronous distributer arm D3 contacts with the segment the relay R5 and the selecting magnet SM5 are energized to produce a spacing signal. A segment PS on the distributer D3 is connected to a punching- magnet MP and a spacing-magnet MS. According to a modification each character is scanned in parallel lines, and divided into sub-areas by a distributer synchronous with the scanning-disc, and segments correspond ing to certain sub-areas for example five, are connected to the selecting- magnets (Figs. 5-7, not shown).

Title: Improvements in or relating to means for operating bulk-head doors
IPC: B63B19/00
Filed: 1931-01-23
Abstract: 371,450. Operating bulkhead doors. HARLAND & WOLFF, Ltd. and BENTLEY, H. H., Queen's Island, both in Belfast. Jan. 23, 1931, No. 2341. [Class 65 (i).] In mechanism for operating sliding bulkhead doors by a nut on a screwed shaft, the shaft is provided with two thrust surfaces, one of which has a rigid bearing while the bearing of other resiliently takes up thrust when the closing movement of the door is arrested. The mechanism is shown in the Figure applied to a vertically sliding door 1, shown open. The door is operated by a nut 6 working between lugs on the door on a screwed shaft 5 which is driven through reduction gearing by a motor M. Clamped to the upper part of the shaft 5 are two ball thrust bearings, the lower races of which bear against shoulders on a fixed bracket 23 and the upper races bear against shoulders on a sleeve 15 pressed downwards by a spring 16. The pressure on the thrust bearings is normally downward, owing to the weight of the door, but if the closing movement of the door is obstructed the thrust is reversed, and the bearings are lifted against the action of the spring. The force exerted by the spring tends to overcome the obstruction, but if the movement of the shaft against the spring exceeds a certain amount switches 27 are operated to open the motor circuit ; these switches may also control an indicator. The same action will occur at the end of the closing movement, the door being forced home by the spring. The nut 6 is free to move a short distance between the lugs on the door, so that the motor can accelerate before taking any load and the nut gives a hammer blow to the appropriate lug to start the movement of the door in either direction. The door and door frame carry at their upper and lower edges clips and wedges which interengage when the door is closed. The door may be operated manually from a distance through a shaft 30 connected to the motor shaft through a solenoid-operated clutch 29 which is disconnected when a master switch is operated. Local manual-operating means (not shown) are also provided, comprising bevel-gearing driving the lower end of the motor shaft. The mechanism may be applied to horizontally sliding doors.

[Class 4.] Hydraulic apparatus for controlling aeroplane landing-wheel brakes comprises a reservoir 16 for liquid under gaseous pressure or under atmospheric pressure, but sufficiently elevated to produce the desired pressure, a mastercylinder 3, the principal piston 2 of which is actuated by the aeroplane skid 1, a distributer 13 enabling the pilot to place the master cylinder into communication with brake - operating members F or with the reservoir 16, an accumulator 4 with which the master-cylinder 3 communicates, and a spring-pressed piston 9 providing through a projection 2<a> on the piston 2 a resilient support for the skid. The accumulator is provided with an elastic device, e.g. a spring-pressed piston 7. Return of liquid after actuation of the brakes is facilitated by means of a spring 19, a valve 18 and a valve 22 providing a byepass between the members F and the master-cylinder, and in order to reduce the rapidity of applying the brakes, a constriction 20 is inserted in the pipe line which may be short-circuited on release of the brakes by a valve 21. The piston 2 may be actuated by pulleys and cables from the skid. The valve 18 may be replaced by a feeding- device of the kind described in Specification 412,769, [Group XXIX], and the members F may be operated through a control system enabling the pilot to graduate the intensity of braking without having to furnish the power or to obtain differential braking this control may be of the type described in Specification 341,007.

IPC: D04H1/4334
Filed: 1962-01-24
Abstract: A leather-like material is manufactured by treating a non-woven web of fibres, of which at least 30% by weight are cellulosic fibres or fibres which have a permanent set of at least 30%, with a non-aqueous dispersion of a thermoplastic polymeric binder containing a plasticiser therefor, the finished leather-like material containing between 10% and 50% by weight of the fibres of the non-woven web calculated on the weight of the finished material, and heating to at least partly gel the dispersion.  The term "cellulosic fibres" covers fibres of natural cellulose such as cotton, regenerated cellulose such as viscose rayon and cellulose derivatives such as cellulose acetate.  After heating, pressure is applied to the web, one side only of which is hot enough to cause the binder to soften on that side but not hot enough to damage the fibres.  The finished material preferably contains between 15% and 40% by weight of fibres. Preferably the non-woven web random laid by air deposition is pre-bonded before the thermoplastic plasticized polymeric bonding agent is added. The web may be needle punched before, after or instead of pre-bonding.  The non-woven web may consist entirely of cellulosic fibres or may contain synthetic polymeric fibres, such as nylon or polyethylene terephthalate, preferably present to the extent of at least 10% by weight of the web.  Specified pre-bonding agents are natural or synthetic adhesives such as starches, synthetic rubber such as acrylonitrile butadiene, polyacrylates such as polyethyl acrylate, and plasticised polyvinyl chloride latex.  Specified thermoplastic polymeric bonding agents are cellulose acetate, ethyl cellulose, polyvinyl butyral, vinyl polymers such as polyvinyl chloride and a copolymer of vinyl chloride with vinyl acetate. Specified plasticizers when the bonding agent is a vinyl chloride polymer or copolymer are sebacates such as butyl benzyl or di-octyl sebacate, phthalates such as butyl benzyl or di-isodecyl phthalate, alkyl phosphates such as trialkyl phosphates, adipates such as di-capryl adipate, alkyl esters of nylon waste acids, e.g. octyl decyl "nylonate", linear polyester plasticizers and epoxidized vegetable oils such as epoxy soya bean oil.  The leather-like material may be coated with a porous plastic film.
