Title: A machine for excavating drains in earth
IPC: E02F5/02
Filed: 1925-04-28
Abstract: 255,931. Cavanagh, A. April 28, 1925. Single-furrow and mole-drain ploughs; implements with adjustable tool frames; adjusting and lifting parts; travelling gear; tools. - An implement adapted to form a drain in stages is provided with attachments which are inoperative while the first cut is made but are afterwards lowered into the channel to guide the implement while it makes a mole drain or succeeding cuts at lower depths. The bent main frame a travels on skids a<3>, a<4> and is provided with a draught ring a<2>. The front guiding attachment consists of a wedge-shaped share b adjustable vertically by a lever b<3>. A bent plough beam c carries coulters c<3>, a narrow share or soil-raising plate c', and two plates c<6>, behind which are splayed deflectors c<7> to push the excavated soil to the sides. The beam c is pivoted at c<2> and connected by a pin and slot to a double rack bar d working in a sheath d<1>. The rack is adjusted by means of a lever e' and double pawls e<2>, a movable bar f being provided for disengaging the pawls from the rack teeth. A slide i, movable vertically by means of a screw i<2> and bevel gearing i<3>, supports a vertical bar j having a knife edge and a mole k at its lower end. Also attached to the bar j is a bracket carrying a wedge-shaped share l which serves as a rear guiding attachment when the mole k is lowered after a sufficiently deep channel has been cut by successive operations of the share c<1>. The guiding shares b, l are approximately the same width as the channel cut. Wheels m<1> are mounted in a cranked axle adapted to be rocked by means of a lever n to raise or lower the rear end of the implement. Instead of forming a mole drain, pipes may be placed at the bottom of the narrow channel cut by the share c<1>.

Title: Improvements in anti-creep checks or anchors for railway rails
IPC: E01B13/02
Filed: 1923-04-23
Abstract: 212,148. Yardley, C. F. April 23, 1923.. Creeping of rails, preventing.-One-piece creepchecks have a substantially straight body 10 with only one rail-gripping jaw 11, 13 at each end, the body, when in position on the rail, engaging the sleeper at one end and extending away from the sleeper at an angle thereto and the jaws being formed at such an angle to the body that the grip on the rail is increased as the anchor is moved towards a position at right-angles to the rail. The jaws may be so formed that movement beyond the transverse position is prevented. The body may be resilient and put under torsion, or it may be rigid and the resiliency confined to the jaws. The jaws are of different lengths and are bent at different angles, and may have dog-eared corners, Fig. 3<b>. The jaws may join the body by curved parts which do not engage the rail base, or by straight parts in engagement therewith, and in the latter case portions 16<a>. Fig. 4, may be removed from one or both sides to facilitate the stamping of the anchor. The anchor may be applied with either end against the sleeper 14.

Title: Process for the production of nitro phenyl amino diol derivatives
Filed: 1951-05-11
Abstract: The invention comprises: (i) the production of compounds of the general formula <FORM:0700710/IV(b)/1> (wherein R represents hydrogen or a carboxylic acid acyl radical, and R1 represents hydrogen, halogen or an alkyl or alkoxy group of 1-4 carbon atoms) by the following steps: (a) reacting a 1-phenyl-2-acylamidopropane-1 : 3-diol of the general formula <FORM:0700710/IV(b)/2> with a thionyl halide (preferably at 20-35 DEG C.) or a carbonyl chloride (preferably below 20 DEG  C.) to form the cyclic sulphite or carbonate thereof, (b) nitrating the phenyl ring and any phenyl ring present in the acyl radical, thus producing a compound of the general formula <FORM:0700710/IV(b)/3> (wherein -Y- represents -SO- or -CO-), and (c) hydrolyzing the product of (b); (ii) step (b) as an independent process, advantageously effected below about -10 DEG C. with fuming or 100 per cent. nitric acid or a mixture of concentrated nitric and sulphuric acids; (iii) step (c) as an independent process when effected under mild conditions in a solvent composed of water and a water-miscible organic solvent with an acidic or alkaline hydrolytic agent so as to produce the compound in which R is an acyl radical in preponderant proportions; (iv) the compounds of the third general formula above; (v) the compounds of the first general formula above when prepared according to (i) or (iii).  To obtain these last compounds in which R represents hydrogen, the hydrolysis step (c) is carried to completion using a dilute mineral acid, or the compounds in which R represents an acyl radical may be further hydrolyzed.  The various products are antibiotics or intermediates therefor.  Examples describe the preparation of: (1) to (4) dl- and lq -1-p-nitrophenyl - 2 - dichloracetamido - and - 2 - amino - propane - 1 : 3 - diol from dl - or l - q  - 1 - phenyl - 2 - dichloracetamidopropane - 1 : 3 - diol via the cyclic sulphites and via the cyclic carbonates; (5) dlq  -1-p-nitrophenyl - 2 - m1 - nitrobenzamidopropane - 1 : 3 - diol from dlq -1-phenyl-2-benzamidopropane-1 : 3-diol via the cyclic sulphites; (6) and (7) dl - q  - 1 - p - nitrophenyl - 2 - acetamido - and -2-amino-propane-1 : 3-diol from dl - q 1-phenyl-2-acetamidopropane-1 : 3-diol via the cyclic carbonates and via the cyclic sulphites; (8) dl - q  - 1 - (31 - methoxy - 41 - nitrophenyl) - 2-aminopropane-1 : 3-diol from dl - q  - 1 - (31 - methoxyphenyl) - 2 - phenylacetamidopropane - 1 : 3-diol via the cyclic sulphites; (9) dlq  - 1-(21 - methyl - 41 - nitrophenyl) - 2 - methoxyacetamidopropane-1 : 3-diol from dlq  -1-(21-methylphenyl) - 2 - methoxyacetamidopropane-1 : 3-diol via the cyclic sulphites; (10) l-q -1-p-nitrophenyl-2-aminopropane-1 : 3-diol from l-q  - 1-phenyl-2-benzamidopropane - 1 : 3-diol via the cyclic carbonates; (11) dl-q  -1-(21-chloro-51 - nitrophenyl) - 2 - (a  - bromopropionamido) - propane - 1 : 3 - diol from dl - q  - 1 - (21 - chlorophenyl) - 2 - (a  - bromopropionamido) - propane-1 : 3-diol via the cyclic sulphites.

[Class 130.] A trough which guides the continuous strip of paper beneath a tobacco-feeding mechanism is mounted on the machine frame so that it can be moved bodily away from the feeding mechanism into an inoperative position to allow the paper to be rethreaded and permit ready access to the trough. A feeding channel consists of a body 6 formed with a U-shaped trough 7 into which project guide-plates 9 carried by bars 8, the channel being mounted on brackets 12 pivoted on studs 14 so that it can be manipulated by a handle 17. The paper P is led into the channel by guides 21 which form a continuation of the guide-plates 9 and have pointed noses to facilitate the threading of the paper between the side of the trough and the guide-plate. Tobacco T is deposited in the channel from a shoot 10, and the charged paper as it leaves the channel enters a rodformer 27 which projects slightly into the trough. According to a modified construction, the trough is secured by a snap-lever which engages a latch on the frame. Also, the side walls of the trough body 6 may be provided with cut-away portions between supports 29 thus forming openings 30 at the side of the grooves ; the inside guides 31 form a series of separate noses 32 and are arranged so that the paper-guiding groove is not closed on both sides at one time.

Title: Process of separating arsenic sulphide precipitates from acids
IPC: C01B17/90
Filed: 1930-04-10
Abstract: In the separation of arsenic, with or without selenium, from acids such as concentrated sulphuric acid by precipitation as sulphide, the separation of the precipitate is assisted by the presence in the acid of inert solid substances such as finely divided sand or alumina, of gases such as nitrogen, hydrogen, oxygen, or air, or of liquid organic substances such as benzene in conjunction with a frothing agent such as pine oil or oil of turpentine.  Mixtures of solids or of gases may be used or solid and gaseous substances may be used in succession, and when hydrogen and oxygen are used, they may be prepared in situ by electrolysis.  In carrying out the process, the assisting substances may be stirred into the solution prior to, during, or after precipitation of the sulphide, and stirring be continued after precipitation; after stirring is suspended, the precipitate settles with the solid when used, or rises to the surface as a scum when a gas is employed, or separates on the surface with the liquid and frothing agent when these are used.  Specification 349,472 is referred to.
