Title: Antiwear additives
Inventor: AGIUS PETER JOSEPH VERMONT JAM
IPC: C10M173/02
Filed: 1953-01-30
Abstract: Lubricating compositions contain a major proportion of a mineral or synthetic lubricating oil or of a hydraulic fluid comprising a major proportion of a blend of a water soluble alcohol and water, an a minor proportion of a monoester or di-ester of sulpho succinic acid or a salt of such a sulpho-succinate.  Salts of mono or polyvalent metals, e.g. sodium and barium, and of amines such as guanidine, are referred to. The alcohols used to form the esters may be branched chain alcohols derived from the oxo process or fatty alcohols derived from animal and vegetable oils, e.g. coconut oils.  Metal dialkyl sulpho succinates, particularly sodium dioctyl sulpho succinate are referred to.  Synthetic lubricating oils specified are ester and polymeric oils.  The lubricating oils may be thickened with soaps to form greases.  The hydraulic fluid may comprise ethylene glycol and water Antioxidants, anticorrosion agents and antifoaming agents may be added to the compositions.  In an example, the lubricating properties of a hydraulic fluid consisting of "Lissapol" (Registered Trade Mark), water, ethylene glycol, turkey red oil, sodium nitrite, sodium mercaptobenzthiazole, a silicone antifoaming agent and sodium dioctyl sulpho succinate were tested.  Specification 738,749 is disclaimed.

Patent GB-830857-A (GB)
Title: Aminoalkyl aryl ethers
IPC: C07D295/092
Filed: 1958-01-29
Abstract: The invention comprises compounds of the formula <FORM:0830857/IV (b)/1> (wherein R is methyl or ethyl, R1 is methylene, ethylene or propylene, R11 is methyl or ethyl and R111 is hydrogen, methyl or ethyl, or R11 and R111 may, together with the vicinal nitrogen atom, form a saturated heterocyclic ring) and acid-addition salts thereof; and their preparation by reacting an alkyl 2-hydroxy-3-methyl-benzoate with a reactive ester of an appropriate tertiary amino alcohol. Suitable reactive esters are halides or alkyl- or aryl-sulphonic esters and the reaction is advantageously carried out in a solvent in the presence of an acid acceptor such as an alkali metal hydroxide, alcoholate or carbonate.  The compounds may also be prepared by reacting the benzoate with, for example, a phthalimidoalkyl halide, a halocarboxamide or a nitrile of a halocarboxylic acid and then converting the phthalimido, carboxamide or nitrile group into an amino group and alkylating this. Amino-propyl ethers may also be prepared by reacting the benzoate with the corresponding acrylic acid derivatives.  A further method for the preparation of the compounds of the invention comprises the splitting off of carbon dioxide from the corresponding carbonates. Examples describe the preparation of compounds wherein R in the above general formula is variously methyl and ethyl, R1 is variously ethylene, trimethylene and propylene and -NR11R111 is variously dimethylamino, diethylamino, piperidino and morpholino, hydrochlorides and phosphates of some of the products also being described.  In further examples, methyl 2-hydroxy-3-methyl benzoate sodium salt and p-toluene sulphonic acid b -chloroethyl ester give methyl-2-(b -dimethylamino-ethoxy)-3-methyl-benzoate and this with dimethylamine gives methyl 2-(b -dimethylamino-ethoxy)-3-methyl-benzoate, which is also prepared by the action of dimethylamine on methyl 2-(b -bromo-ethoxy)-3-methyl-benzoate, itself prepared from the sodium salt of methyl 2-hydroxy-3-methyl-benzoate and ethylene dibromide. Specification 822,931 is referred to.ALSO:Veterinary and pharmaceutical anaesthetic compositions comprise one or more compounds of the formula <FORM:0830857/VI/1> (wherein R is methyl or ethyl, R1 is methylene, ethylene or propylene, R11 is methyl or ethyl and R111 is hydrogen, methyl or ethyl, or R11 and R111 may, together with the vicinal nitrogen atom, form a saturated heterocyclic ring) or acid-addition salts thereof in admixture with a pharmaceutical carrier or carriers.  Specification 822,931 is referred to.

Title: Lock-stitch sewing machines
IPC: D05B57/14
Filed: 1929-01-30
Abstract: 318,460. Fairweather, W., (Singer Manufacturing Co.). Jan. 30, 1929. Lock-stitching by hooks. - In a lock-stitch rotary-hook machine, the cup-shaped hook has an open-sided raceway for the bobbin case and a bobbin case retainer. The rotarv-hook shaft 6 is driven twice as fast as the needle 2 and carries the cup-shaped body 7 with the beak 8 and opensided raceway 9 which receives the bearing rib 10 of the bobbin-case 11. The case is held in position by the retainer head 12 which has a pin 13 fixed in the arm 14 by the screw 15. The arm 14 is pivoted on a shaft 16 journaled in the bracket 17 to enable it to be swung outwardly as indicated by the dotted lines in Fig. 1 for removal of the bobbin-case 11. The toe 20 of the arm 14 engages the wall 21 of the slot in the bracket 17 to limit its outward motion and the plate 22 screwed to its base limits its inward motion. A bow spring 25 secured at one end to an arm 23 fixed to the pivot shaft 16 and at the other end to a pin 26, urges the arm 14 to either of its extreme positions. The retainer arm 14 is locked in its operative position by the engagement of the shoulder 27 of a latch 28 with the bracket 17, Fig. 2. It is released manually. The bobbin-thread passes through the notch 36 which engages the rotation-restraining tongue 39 on the retainer 12. A pull-off flange 43 operating in a cylindrical path overhangs the retainer 12. This flange begins just behind the throat 44 of the hook, Fig. 9, and continues for just over 180‹. and pulls-off the desired amount of bobbin thread with a minimum amount of width of flange.

The binder may be of the ring or post type and the sheets may be provided with notches instead of holes. When the binder is full the covers 10, 11 may be removed, the sheets trimmed at the edges, and flexible members sealed to a permanent binder or cover may be passed through the holes 3 or additional holes, or the assembly may be stitched with wire or thread or secured by bent-over nails. In a modification, the binder may comprise, in addition to rings or other binding means, bound-in stubs which may carry adhesive as well as or instead of the sheets 1.

Title: Improvements in glide path systems for aircraft
IPC: G01S1/02
Filed: 1941-03-11
Abstract: 582,081. Radio navigation. STANDARD TELEPHONES & CABLES Ltd., and WILLIAMS, H. P. March 11, 1941, No. 3298. [Class 40 (v)] In a glide-path system for aircraft, the distance of the craft from the transmitter is determined, e.g. by a reflection system in which a beat frequency indicates the distance, and a signal representing this distance is transmitted by amplitude modulation to the aircraft where a derivative depending upon the frequency of the modulation (i.e. upon the distance) is compared with the energy level of the beam. The distance is determined by. a frequency modulated beam in known manner, the reflected or re-radiated beam producing beats which are used to amplitude-modulate the same beam. The beam may be re-radiated from the aircraft at double the frequency of the transmitter. Fig. 4 shows the equipment on the aircraft. The waves, modulated in frequency and amplitude received at RR, are amplified at AMP, and pass through a highfrequency filter to a detector. Part of the beat frequency thus produced passes through a frequency-measuring instrument FM to a distance indicator D1 and part passes through a low-frequency limiter LFL and filter LFF to the amplifier AMP, the low-frequency output of which passes through a low-frequency filter LF to a further detector and meter M, by which it is compared with the D.C. component of part of the output of the other detector representing the field strength. The lowfrequency filter may give an output which varies with the frequency (i.e. the distance) in any desired relation. Part of the output of the high-frequency filter passes through a frequency-doubler FD and is re-radiated at RT.
