Title: Improvements relating to the safe working of hydraulic elevators
IPC: B66B1/04
Filed: 1923-11-07
Abstract: 226,334. Hunter, J. S. Nov. 7, 1923. Valves controlled by pilot or relay valves.-In hydraulic lifts each well door is associated with one of a series of valves, the arrangement being such that when all the doors are closed pressure water flows through the series of valves to open a cut-off valve arranged in the supply pipe of the driving mechanism. When any door is open, the flow of water is stopped and the cut-off valve is closed by a spring, weight, &c. to stop the lift. The cage 6, Fig. 1, is suspended by the rope 7 and is actuated by the ram 8 working in the cylinder 9. The control rope 19 is attached to a bell-crank lever 20 which is connected by a link 21 to the plunger of the control valve 18. A pressure pipe 22 connects the valve 18 to the regulator valve 23, and the pipe 24 connects the valve 23 and cylinder 9. Exhaust pipes 25, 26 are connected to the valves 23, 18. A pipe 31 conveys pressure water from the service pipe 16 to a cylinder 15 on the top floor. Similar cylinders 14, 13 are provided at the other floors and are connected by a pipe 33. A pipe 34 connects the lowest cylinder to the control cylinder 27 for the regulator valve, and exhaust pipes 37, 36.' 35 opening into a pipe 38 put the cylinders into communication with the main exhaust pipe 26. Within the bore of each cylinder are four tubular distance-pieces 44, Fig. 2, holding in position three annular U-leathers 45. The two middledistance-pieces are perforated, but the end ones have solid walls. A tubular plunger 46 slides axially through the U-leathers and has two series of radial apertures 51, 52 which in the position shown, i.e. with the door open, register with the perforated distance-pieces and pressure water therefore cannot pass from the pipe 31 to the pipe 32 and thence through the other cylinders to the valve 27. A rod 47 attached to the plunger 46 carries a roller 50 against which the door bears during closing. When the door is closed, the plunger has been moved sufficiently far to the left to allow fluid to pass from the pipe 31 to the pipe 32. When fluid is admitted to the valve 27, the plunger 64 is moved to the left, Fig. 4, against the resistance of the weight 28 and shifts the plunger 59 to a position which permits communication between the pipes 22, 24. If the valve 18 is now opened by moving the control rope 19, pressure fluid is admitted to the cylinder 9 and the lift is raised. If the valve 18 is set to exhaust, water flows from the cylinder 9 and escapes through the pipe 26 while the lift descends. If any door is opened, the pressure in the valve 27 is not maintained, and the plunger is moved by the weight 28 to the right, thereby stopping communication between the pipes 22, 24.

Title: Improvements in or relating to the manufacture of resinous phenolic condensation products
IPC: C08G8/28
Filed: 1928-10-02
Abstract: 323,275. Wade, H., (Bakelite Corporation). Oct. 2, 1928. Phenol-methylene resins.-Permanently fusible phenol-methylene condensation products, which may contain an excess of phenol, are converted into a potentially reactive resin in which a methylene containing body, e.g. hexamethylenetetramine or formaldehyde, is added to the fusible resin, by first incorporating a phenolic body, which includes cresols and other phenolic bodies or mixtures thereof, and then adding the methylene containing body in such a quantity that the resulting methylene-phenol ratio of the mixture is higher than that of the initial condensation product. The phenolic body is added, prior to the final addition of methylene body, in an amount sufficient to give an excess of phenol over the methylene content of the resin (e.g. sufficient to give a phenol-methylene ratio of 9-12 :6). The methylene containing body is then added in a quantity sufficient to give approximately equimolecular proportions of phenol and methylene in the mixture, and a basic catalyst, preferably ammonia as such or in the form of hexamethylenetetramine, hexamethylenetetramine tri-phenol &c., may be added in a proportion equal to 0.1 per cent of the dry resin. The potentially reactive resin thus obtained may be hardened in the presence of fillers &c. to give transparent products, moulding mixtures &c. and may be used for the manufacture of varnishes, impregnating liquids &c. Other aldehydes, e.g. acetaldehyde, furfuraldehyde, benzaldehyde &c. also may be employed.

Title: Process for the production of cross-linked plastics of high molecular weight
IPC: C08G18/87
Filed: 1959-08-19
Abstract: In a process for the production of cross-linked plastics from isocyanate-modified polyhydroxy compounds and sulphur in the presence of known rubber vulcanization accelerators, there are used saturated isocyanate-modified polyhydroxy compounds which have been obtained by reacting a linear polyhydroxy compound having a molecular weight of higher than 1,000, an alkyl substituted N-di (oxyalkyl) phenyl amine and an amount of a diisocyanate equal to or less than that required for reaction with the total number of reactive hydrogen atoms contained in the other two reactants.  Polyesters, polyethers, polythioethers and polyacetals containing hydroxyl groups are examples of suitable compounds of molecular weight above 1,000. Suitable diisocyanates are 4, 41-diphenyl methane-, hexamethylene-, 1, 4-and 1, 5-naphthylene- and hexahydro-p-phenylene diisocyanates. Specified amines are N-di(oxyethyl)- m-toludine, -3, 5-xylidine-2, 6-diethylaniline and -2, 6-dimethyl aniline, and the corresponding di(oxyisopropyl) derivatives.  The hydroxy compounds may be reacted together or successively with the polyisocyanate. 2-Merccaptobenzthiazole, 2-mercaptobenzthiazyl disulphide and their zinc chloride addition compounds are suitable accelerators. In Examples (1) a glycol adipic acid polyester is reacted with 4, 41-diphenyl methene diisocyanate and the product is reacted with N-di(oxyethyl)-m-toluidine.  The resulting melt is heated on metal plates at 100 DEG C.  The material obtained is mixed on rollers with sulphur, mercaptobenzthiazole, 2-mercaptobenzthiazyl disulphide and its zinc chloride complex, carbon black and stearic acid and the mixed is pressed at 150 DEG C.; (2) a 1, 2-propylene glycol-adipic acid polyester and (3) a tetrahydrofuran polymer are reacted similarly.

Title: Improvements in and relating to refrigerating machines
IPC: F25B23/00
Filed: 1919-11-17
Abstract: 163,360. Stockel, F. C. Nov. 17, 1919. Refrigerating, vacuum machines and processes for, of the kind employing sulphuric acid or the like to absorb water vapour, are provided with a freezing-chamber P, a pump A, and an absorption drum R firmly connected and adapted to be rotated together in a collar H on turning a handle Q. Communication between the chamber P and drum R is effected by means of a common airpassage N. In order to increase the absorption and cooling effect, the drum R is ribbed and is immersed in a vessel T containing cold water. The pump piston C is operated and at the same time is prevented from rotating relatively to the other elements by means of a cross-head F attached thereto, which works in vertical slots L in the neck of the pump-barrel and which traverses a grooved track G in the collar H. During the upward movement of the piston C, a quantity of oil is cut off in a cavity B in the pump barrel until the lower edge of the piston has passed, whereupon it flows down to the bottom of the pump cylinder A. Near the end of the upstroke of the piston, a cross-piece 1 engages the head of a valve piston K and opens a valve J, whereupon vapours from the drum R pass into the vacuum which has been created in cylinder A. On the down stroke of the pump piston the valve J is closed and the piston pushes the oil and vapours upward through a valve E, where the vapours escape to the atmosphere and the oil flows downwards and is used again, thus functioning as an air-trap.

Title: Improvements in or relating to saturable reactor stabilising arrangements for a.c. systems
IPC: H02J3/01
Filed: 1947-10-27
Abstract: 629,829. Protective arrangements ; transmission line arrangements. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Oct. 27. 1947, No. 28629. [Class 38 (iv)] To minimize or suppress harmonics, particularly the fifth and seventh, in a stabilizing arrangement of of the A.C. or D.C. saturable reactor type for a three-phase electric supply system, a second harmonic accepter filter is associated with the reactors, which are arranged in two groups, each comprising three star- or interstarconnected reactors provided with a magnetic leakage path, the two groups being so connected to the A.C. system that there is a relative phase displacement of 30 degrees in their magnetic fluxes. The two groups may be connected together in parallel, series or cascade. In the arrangement shown in Fig. 1, groups 2, 3 of reactors 1 are connected across a three-phase line 4 which is also shunted by three starconnected second harmonic filters 9, 10. The reactors of each group are interstar-connected and their line connections are such that the fluxes in the two groups lead and lag, respectively, by 15 degrees the flux which would obtain with a simple star connection. The windings 10 of the second harmonic filters may be wound one on each limb of a three-limbed core having air-gaps distributed over each limb. The filters may be connected to interstar-connected secondary windings on one of the reactor groups instead of directly shunting the line 4 ; or a single filter connected across two phases may replace the star-connected arrangement shown. The windings of each reactor group may be accommodated on a three-limbed core 6, Fig. 2, having magnetic shunts 7 which may be provided with air-gaps so dimensioned as to suppress the eleventh harmonic or to reduce both the eleventh and thirteenth harmonic. This reduction may also be effected, instead of by air-gaps, by providing on the individual cores of the reactors secondary windings which are connected in open mesh to reactors of appropriate magnitude. The arrangement may be used to protect a meshconnected transformer against possible harmonic instability, by connecting the arrangement in parallel with the transformer and operating the reactors at a higher flux density than the transformer. Specification 610,061 is referred to.

Title: Apparatus for dispensing measured quantities of several liquids in predetermined ratio
IPC: F02B75/02
Filed: 1952-11-14
Abstract: 712,386. Mixing liquids in proportion. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Nov. 14, 1952 [Nov. 16, 1951], No. 28744/52. Class 86 [Also in Group XXVIII] Apparatus for dispensing measured quantities of two liquids in predetermined ratio comprises a piston and cylinder for the delivery of each liquid, the two pistons being coupled through an adjustable lost motion means whereby the ratio is adjustable, and the pistons and cylinders being so disposed with respect to each other that in each working cycle of one of the pistons, the aggregate quantity of liquid dispensed is the same. In an apparatus for dispensing petrol proportionately mixed with one of three types of lubricating oil, three cylinders 1 containing pistons 3 and connected to a petrol reservoir and to a collecting tank for petrol and oil by cam operated inlet and outlet valves, Fig. 2 (not shown), are disposed above a crankshaft 9 which is connected to each of the pistons 3 by connecting rods 8. A cylinder 2 is mounted upon each of the cylinders 1 and each is connected to a reservoir of a different type of oil and contains a piston 4 carrying a hooked element 21 and an axially adjustable element 20. A pin 19 carried by the piston 3 extends between the elements 20, 21 and when the piston 3 reciprocates it imparts reciprocation to the piston 4 with an amount of lost motion depending upon the spacing between the elements 20, 21 which determines the amount of oil delivered from the cylinder 2 into the collecting tank. Each element 20 is carried by a member 22 screw threaded into the piston 4, the member 22 being rotatable by a manually operated external control mechanism to displace the element 20 axially. The external control mechanism includes a control knob associated with each of the cylinders 2, such knobs being interlocked so that it is impossible for more than one of the cylinders 2 to deliver oil. To provide for delivery of the same aggregate volume of petrol and oil for each working stroke of the piston 3, a volume of petrol is displaced into a space uncovered behind the piston 4 during its working stroke, equal to the volume of oil delivered from the cylinder 2. The apparatus described is driven by the hydraulic pressure of the petrol. More than three types of oil may be provided for by correspondingly increasing the number of pistons and cylinders, in which case, in order to obtain a desired maximum oil-petrol ratio, one or more of the petrol cylinders may be excluded from delivery by providing return lines in the petrol discharge conduit. A liquid quantity recording means 33 may be driven by the apparatus.
