Title: Improvements in or relating to photographic apparatus
IPC: G03D3/10
Filed: 1928-04-19
Abstract: 312,766. Smith, W., and Langlands, T. F. April 19, 1928. Automatic and coin-freed apparatus for taking and finishing photographs ; continuous apparatus for developing. -, In an automatic camera the strips of film after exposure are dipped into a series of tanks containing developing and fixing solutions by a relative motion of a film carrier and the tanks. The developing apparatus comprises a carrier consisting of two endless chains united at intervals by bars a carrying loops b to hold the strips of film c. The carrier is mounted on a frame i supported on a vertically movable - standard k, which is operated through links k<1>, k<2>, k<3> by a main cam l. The surfaces l<1> - - l
 on the main cam are designed to dip the films into each tank five times, before an elevated part l<6> raises the standard k sufficiently to enable a fixed collar m to operate ratchet mechanism m<4> for moving the carrier to bring each loop into a position over the next adjacent tank, the operation being repeated till every strip has passed through all the tanks. Alternatively the carrier may comprise a number of radial arms on a spindle, the tanks being arranged ciroumferentially. The film, mounted on a reel d, is intermittently fed through .a guide into the exposure position by a feedroller e. After exposure, the film is enclosed between grippers g, fed into the loops, and severed from the stock by a guillotine o. The main cam spindle has a series of fingers n<1>, n<2>, n<3> operating through link mechanism n<11>, n<22>, n<33>, the grippers g, the feed roller e, and the guillotine o respectively. Means for delivery of the completed picture comprise an angularly-oscillating link having spring-controlled grippers adapted to come together and grip the film strip in the loop over the final drying-tank h<7> when the link is in one of its extreme positions. The strip is withdrawn from the loop by the backward movement of the link and carried to the other extreme position of the link, where the grippers open to deposit the strip on a table which subsequently rotates to eject it into a shoot. Fig. 5 shows the electrical controls. A coin t closes the switch t<1> thereby completing the circuit for the motor t<2>, the heating coil t<3> and the magnetic clutch by which the fingers n<1>, n<2>, n<3> are brought into operation, t<4> is a ratchet-operated switch controlled by the main cam and designed to keep the motor running until all the strips have passed through the machine. A further switch t<5> operated by the link k<1> is adapted to maintain the motor running until the loops b are raised out of the tanks. The shutter and lighting system are also adapted to be operated from the main cam.

Title: Manufacture of artificial resins
IPC: C08G8/00
Filed: 1937-04-23
Abstract: Saturated aliphatic hydrocarbons substituted by at least three hydroxyaryl groups are hydrogenated at about 150-300 DEG  C. under pressure in the presence of a hydrogenation catalyst and in the presence or absence of a solvent.  Resinous products which can be boiled in linseed oil, and which contain alcoholic groups capable of being etherified or esterified, are obtained.  The hydrogenation may be complete or partial, and may be effected continuously in a long tube.  Suitable starting materials are obtained by condensing phenol or its homologues or naphthols with mono-or poly-chlorinated saturated or unsaturated aliphatic aldehydes or ketones, or with aliphatic aldehydes or ketones containing at least one hydroxyl group, or with unsaturated aliphatic aldehydes or ketones.  Typical starting materials are the compounds of the following formulae in which R indicates a p-hydroxyphenyl group: (1) CH3CR2CH2R, from phenol and monochloracetone; (2) RCH2CR2CH2R, from phenol and sym. dichloracetone; (3) CH3CR2CHR2, from phenol and asym. dichloracetone; (4) RCH2CR2CHR2, and CH3CR2CR3, from phenol and trichloracetones; (5) R2CHCR2CR3, from phenol and pentachloracetone; (6) CR3CR2CR3, from phenol and perchloracetone; (7) CH3CH2CR2CH2R, from phenol and chloromethylethyl ketone; (8) RCH2CHR2 from phenol and chloracetaldehyde; (9) CH3CHRCR2CH3, from phenol and vinylmethyl ketone, with addition of phenol to the double bond; (10) CH3CH2CHRCHR2, from phenol and crotonaldehyde; (11) RCH2CH2CHRCHR2, from phenol and g -chlorocrotonaldehyde; (12) CH3CH2CH2CHRCH(C2H5)CHR2, from phenol and 2-ethyl-3-propylacrolein; and (13) CH3CHRCH2CHR2, from phenol and aldol.  Suitable starting materials are also obtainable by condensing more than one phenol with one of the specified aldehydes or ketones; thus, one mol. of monochloracetone may be condensed with two mols. of phenol and one mol. of a cresol, or with one mol. of phenol and two mols. of a cresol.  Examples are given of the hydrogenation of (1) 1 : 2 : 2-triphenylolpropane; (2) 1 : 2 : 2 : 3 - tetraphenylolpropane; (3) 1 : 2 : 2-tricresylolpropane (from crude cresol and monochloracetone); (4) diphenylolcresylolpropane, prepared by condensing two mols. of phenol and one mol. of crude cresol with one mol. of monochloracetone; (5) 1 : 1 : 3-phenylol-2-ethylhexane; (6) a condensation product from crotonaldehyde and phenol; (7) triphenylolbutane obtained from aldol and phenol; (8) triphenylolethane obtained from chloracetaldehyde and phenol; (9) triphenylolbutane obtained from vinylmethyl ketone and phenol.

Patent GB-396107-A (GB)
Title: Improvements in or relating to the hydration of olefines
IPC: C07C29/04
Filed: 1931-12-22
Abstract: The hydration of olefines is effected by reaction with water or steam in presence of a chloride of acid character of a metal at least as electropositive as nickel and having considerable affinity for water so that it is soluble in about twice the weight of water.  Suitable chlorides are those of zinc, calcium and magnesium.  They may be used solid, in solution, or molten; thus partially hydrated calcium chloride may be used in molten state under sufficient pressure to prevent evaporation of water.  The temperature may be 100-350 DEG  C. or more, and pressures of 15-25 atmospheres or more may be used; when aqueous solutions are used, the pressure should be enough to prevent loss of water, and the temperature should be below the critical temperature of water, i.e. below 365 DEG  C.  The chlorides may be supported on inert carriers such as pumice, kieselguhr, or charcoal, or the gases may be passed through the dissolved or molten chlorides or through towers in countercurrent therewith.  For producing ether, two or more volumes of ethylene may be used for one volume of steam, while for alcohol equal volumes may be used.  In an example, a mixture of 3 volumes of ethylene with 2 volumes of steam is passed through molten zinc chloride at 300 DEG  C. and 20 atmospheres pressure.

Title: Method of producing wood pulp
IPC: D21B1/12
Filed: 1956-04-20
Abstract: 825,216. Making wood pulp. BAUER BROS. CO. April 20, 1956 [April 21, 1955], No. 12243/56. Class 96. In the production of ground wood pulp from raw uncooked wood, the raw wood is chipped, the chips are fiberized by successive applications and releases of pressure, the fiberized material is refined by further fiberization, and the refined fiberized material is cleaned and screened. In Fig. 1 raw wood passes through a chipper 1 and the chips are introduced into a soaking vat 2. the vat also containing, if desired, a wetting agent or softening agent, e.g. sodium hydroxide. Treatment by soaking may, however, be omitted. The chips are passed to a rotary press 3 in which they are fiberized by successive applications and releases of pressure from a rotating helical feed screw, thereby expelling moisture and natural fluids from the wood, e.g. sap, rosin, which are disposed of as by-products. Material leaving the press 3 is preferably wetted and passed to an attrition mill 4, which may be of the rotary disc type and consisting of a single or double disc mill, and then to a second attrition mill 5 to complete the refining by further fiberization. The pulp passes to a centrifugal cleaner 6 to remove dirt, dark specks, &c., which are rejected as waste, while the pulp is graded by a rotary screen 7 from which any insufficiently fiberized pieces are returned to the rotary press 3. Material passed by the rotary screen comprises finished pulp of the ground wood type. In modifications of the process of Fig. 1, (a) the positions of clearer 6 and screen 7 are reversed; (b) rejects from screen 7 are passed to mill 4 instead of press 3; (c) steps (a) and (b) are combined; (d) screen 7 is interposed between mills 4 and 5 and the acceptable products from screen 7 then by-pass mill 5 to cleaner 6 while rejects from the screen pass to the mill 5, thereby preventing over-refining of pulp material.

Title: Improvements in and relating to railway signal systems
IPC: B61L3/10
Filed: 1920-05-03
Abstract: 167,272. Margotta, H. May 3, 1920. Electrical systems, automatic; track apparatus for actuating signals on trains. - An automatic system which dispenses with the usual track relays, has a series of contacts on the track energized from the train to cause the operation of circuit-closers in advance of the train so energizing another series of contacts which cause the operation of signal devices on other trains. Three brushes 12, 13, 14, Fig. 7, are carried by, but insulated from, one of the axles of the train, and make contact with various contacts on the track according to the direction of travel. The wheels are electrically connected through the axle 10 and batteries W, W<1> supply the contacts and the relays 16, 17, 17<1>, 18 which control the signal lamps. The ends of the rail sections 1, 1<1> overlap so that wheels on a common axle are for a short distance on rails of adjoining sections. Contacts 2, 3, 4 &c. are arranged in the track, and tho contact 2 is placed a short distance in advance of the section 1 to which it is connected electrically. If a. train is about to enter a section with a train already on the track, its brush 12 makes contact with the contact plate 2, and a circuit is completed through the wheels and axles of the forward train and the relay 18, thereby causing a green light to indicate the presence of a train in that section. When a train is about to leave a section with another train upon it, an indication is given by a blue lamp controlled by a relay 16. which is energized when the contact arm 13 is lifted to touch the point 13<2> by engagement with the cam contact 8<a> the circuit being completed through the axles of the following train. If two trains are approaching each other, a red lamp is switched on each train by the relays 17 which are energized through the track contacts 5 and the train contact brushes 12. These track contacts are energized by the operation of several of the circuit closers 22 ahead of the train, the closure taking place when the electromagnets 20 are energized by the engagement of the train contact brush 13 with the track contact 3. A complete set of circuit-closers and contacts is disposed on each side of the track so that each train receives the signal. As the train passes, the circuit-closer is opened by the electromagnet 28 which is energized through the contact 4. Broken track rails are indicated by a lamp controlled by the relay 17'. One end of each rail section 1 is connected to a track contact 2 and the other end to the armature 35 of a magnet 36, which is normally energized when the circuitclosers are energized. When the rails are sound the armature 35 is attracted and thereby connected to earth, and a circuit is completed through the contact 2, rail 1, armature 35, earth and contact 6. This circuit includes the magnet 38 on the train and this in turn controls the lamp relay 17<1>. An additional battery is provided on the train for maintaining the signal circuits after the train has passed the track contacts.

[Class 83 (iii)] Clamping-mechanism for the slides of drilling, milling, and like machines having a slide movable along two guideways coacting with two clamping members actuated by a single operating member is characterized by the provision of a wedge system comprising for each guideway 2, 3, Fig. 1, a group of at least two wedges 6, 8 and 7, 11, respectively, movable one along and relative to the other and connected each to one of the two clamping members, respectively, the operating member including a rod 13 traversing both groups of wedges and screwing into one of the wedges 8 of one group while abutting against one of the wedges 11 of the other group, so that upon rotation of the rod through the handle 14 the two wedges of either group move transversely relative to the rod in opposite directions. A third wedge 9, 10, respectively, is used in each group and these are spaced apart by a distance piece 12 through which the operating rod passes. On turning the hand lever 14 to clamp the slide, the middle wedges of each group are pressed towards the guideways and operate through rods 5 to rotate levers 20, Fig. 2, pivoted at 21, to grip the guideway at points 22, thus forcing the slide against the guideways ; the outside wedges of each group are at the same time forced away from the guideways and draw plates 19 on the opposite side of the guideways towards the latter to effect clamping of the lower part of the slide.
