Title: Improvements relating to overhead cranes
IPC: B66C11/20
Filed: 1942-04-08
Abstract: 623,723. Overhead travelling cranes ; winding and paying-out apparatus. SOC. FRANCAISE DE CONSTRUCTION DE BENNES AUTOMATIQUES. April 8, 1942, No. 4619. Convention date, May 27, 1941. [Classes 78 (iv) and 78 (v)] In an overhead crane of the kind comprising a carriage movable to and fro along a track and carrying a hoisting cable controlled by a winch, an electric motor carried by the carriage is adapted to exert an additional force on the hoisting cable in its lowering direction so as to prevent excessive sag in this cable. Fig. 1 shows the application to a carriage which runs on a track 2 and is provided with a hoisting cable 4 operated by a winch at 21 and running over a pulley 3 on the carriage. When the carriage reaches the position in which a load is to be deposited and the hoisting winch rotated in the direction for lowering the load, a motor 6 on the carriage is operated automatically so as to drive the pulley 3 through belt or chain gearing 5 in the direction for lowering the load. Current is supplied to the motor through wires 7 connected to a member 8 which engages bars 9 secured to the track 2 and fed by a supply cable 18 connected to the controller of the hoist winch motor. This connection is such that the bars 9 are alive only when the winch motor is connected so as to drive the winch in the direction for unwinding the cable 4. A roller 11 on levers 10 is pressed against the cable 4 by a weight 12 or springs to ensure that the cable is driven by the pulley 3 without slip. The hoisting winch may serve to traverse the carriage in one direction and the counterweight in the opposite direction.

Title: Improvements relating to commutators for dynamo electric machines
IPC: H01R43/08
Filed: 1950-02-23
Abstract: 704,948. Moulded commutators. HOOVER, Ltd., and CAMPRUBI, B. Feb. 16, 1951 [Feb. 23, 1950], No. 4677/50. Class 35 The segments of a moulded commutator are separated by a different plastic insulating material from the main plastic body, the final curing of both insulating materials taking place simultaneously as the main body is moulded into position. The insulation between segments has antitracking properties, e.g. a melamine type resin having a mineral filler, while the inner part which secures the segments is of a resin, e g. of phenolic type with a cellulose and asbestos filler, having good mechanical properties. In one form, Fig. 3, the commutator is made by extruding a slotted ring or by bending a strip 9 which has previously been slotted, to produce a ring of segments 15 joined by an external strip 16 which is machined off after moulding. The anti-tracking insulation is moulded between segments, and has a dovetailed anchoring rib 18 which adheres to the core 19 which is subsequently moulded in position to secure the assembly about the mounting bush 20. Alternatively the insulation between the segments may be inserted as strips either when the segments are in the form of a ring or when they are still in the form of a strip, so that on bending round they grip the insulation, the phenolic body being moulded as before. As shown in Fig. 5, the premoulded melamine strips. 22 are T-shaped, while in Fig. 6, the slots 12 in the bar 9 are filled with melamine powder 27 which is compressed to the correct volume when the bar is bent into a ring. If desired Fig. 7 (not shown) the insulating strips may be pushed into the slots between the segments when these are in circular form and for this purpose they are carried on an integrally moulded ring from which they extend axially. In further forms, the melamine insulation is used to impregnate fibrous material, e.g. rags, paper, or glass or asbestos cloth, for insertion between the segments either by winding in tape form zig-zag through the slots, or by forming the material into a strip having punched out or integrally moulded tabs which enter the slots between the segments, the segments being subsequently bent into a ring to grip the insulation. Specifications 541,557, 584,867, 603,905, and 642,297, [Group XXII], are referred to.

Abstract: 827,845. Moulding hollow articles. SZEGO, P. Feb. 16, 1956 [Feb. 16, 1955], No. 4687/55. Class 87(2). [Also in Group XVII] A machine for forming a hollow article by drawing a sheet against a shaped mould or for packaging articles between a sheet of thermoplastic material and a backing member by heating the sheet and drawing it down by suction over the article and onto the backing member, comprises elements in which the sheet and mould or the portions of the package can be assembled for passage to the heat and suction applying means. In one embodiment, two linked containers 28, 29 run on rails 24, 25 extending from an assembly position to beneath the heater 20 and to a position 11 for withdrawing the packages. Each container has a perforated base 34 on which is placed the backing member with the article above it. The thermoplastic sheet is clamped by a frame 35 across the mouth of the container. When an assembly is beneath the heater, wheels 31 enter dips in the rails causing a sealing member 32 on the bottom of the container to contact a platform having a suction aperture. Suction is applied after infra-red heating by the member 20 and the assembly traversed to the unloading position, the other linked assembly then being drawn beneath the heater. In another embodiment a series of separate containers on a tilted curved or circular track may roll by gravity beneath the heater, movement being controlled by stops. Alternatively an intermittent conveyer mechanism (not shown) may be used. A preheater (not shown) for the sheet may be provided. The gauge of the rails may be adjustable to suit different sizes of assembly elements. Reference has been directed by the Comptroller to Specification 784,503 [Group XVII].

Abstract: 1356709 Protective arrangements A P RODRIGUEZ 2 Feb 1972 [6 Feb 1971 17 June 1971] 4900/72 Heading H2K An excess current protective arrangement comprises a cut-out switch 1, a solenoid 6 to open the switch when energized, a changeover switch 7 having a first position I in which it connects the solenoid across the switch 1 and a second position D in which it completes a circuit to energize the solenoid, and a bi-metallic element 3 heated by the excess current through a load 5 to operate the changeover switch from position I to position D. Thus in the event of excess current, the bimetallic element 3 operates the changeover switch to connect the solenoid across the supply conductors R, S so that the switch 1 is opened. When the bimetallic element cools the changeover switch 7 is returned to its first position I before the switch 1 can reclose so that the solenoid remains energized until the supply is interrupted, the switch 1 then automatically reclosing. In a double pole arrangement a further switch 2 is operated by the solenoid but a resistor 8 is provided across the switch 2 so that the solenoid 6 may remain energized when the switch 2 is opened.

Title: Reaction products of triglycidyl cyanurate with dihydric phenols
IPC: C07D405/14
Filed: 1958-02-17
Abstract: Resinous products are obtained by reacting triglycidyl cyanurate with a dihydric phenol, e.g. resorcinol, dihydroxy diphenyl, p:p1-dihydroxy diphenyl dimethyl methane or dihydroxy diphenyl sulphone.  Catalysts for the reaction are tertiary amines and quaternary ammonium hydroxides, salts or ion-exchange resins and reaction may be effected in the presence of a solvent, e.g. dioxane. Soluble, fusible resins containing epoxide groups, curable by heating with tetramethylene pentamine, are produced when using a molar ratio of triglycidyl cyanurate to dihydric phenol between 2:1 and 6:5. Cross-linked products are produced when using a molar ratio between 6:5 and 4:9.  Both products are suitable for use in surface coatings, adhesives or mouldings.  Polyhydric phenols suitable for making epoxide resins or for crosslinking with diepoxides (e.g. diglycidyl ethers of dihydric alcohols or phenols) are produced when using a molar ratio of triglycidyl cyanurate to dihydric phenol between 4:9 and 1:3.  Specification 768,470 and U.S.A.  Specification 2,809,942 are referred to.ALSO:New compounds are obtained by reacting triglycidyl cyanurate with a dihydric phenol, e.g. resorcinol, dihydroxy diphenyl, p:p1-dihydroxy diphenyl dimethyl methane or dihydroxy diphenyl sulphone.  When using a mol. ratio of triglycidyl cyanurate to dihydric phenol between 2:1 and 6:5, polyepoxides result, the former ratio giving a compound of formula <FORM:0840181/IV(b)/1> where R is the residue of the dihydric phenol. When using a mol. ratio between 6 : 5 and 4 : 9 and stopping the reaction short of completion, products result containing both epoxy and phenolic hydroxy groups.  When using a mol. ratio between 4 : 9 and 1 : 3 polyhydric phenols result, which will contain epoxy groups if the reaction is not carried to completion, the latter ratio giving a compound of formula <FORM:0840181/IV(b)/2> Reaction is preferably effected in the presence of a catalyst e.g. a tertiary amine or a quaternary ammonium hydroxide, salt or ion-exchange resin.

Abstract: 348,218. Rolling tubes. BEAUMONT, J. H., 329, High Holborn, London.-(Kroydon Co. ; Maplewood, New Jersey, U.S.A.) Feb. 15, 1930, No. 5149. [Classes 83 (ii), 83 (iii), and 83 (iv).] Making golf clubs; rolling mandrels and mandrel supports ; chucks.-Tapered tubes e.g. golf club shafts are drawn from ordinary tubes by pulling the rotated tube 13 between a mandrel 44 and a ring of balls 39, the ring of balls being contracted gradually to give the taper by moving them along a conical die 40 as the work proceeds. In operation the tub 13 is pushed over a mandrel 44 until its end can be entered in a chuck 12. The chuck is rotated by chain sprocket 22. The drawing head 3 carrying the drawing ball ring 39 and mandrel 44 &c. is moved gradually to the left by lathe feed screw 4 but at the same time the ball ring 39 and mandrel is given a relative movement to the right to contract the ball ring gradually against the die 40 and to feed the mandrel correspondingly, this movement being obtained from screws 26 which rotate by being pulled through nuts 24 and which have at their other ends screw threads 34 which advance the ball adjusting head 36 with the ball cage 38 and mandrel 44 relatively to the right. The torsional strain set up by this machine may be relieved by reworking in the similar machine in Fig. 6 in which a mandrel 51 is integral with the tube-clamping head 17 of the chuck 12 to rotate with it, the tube thus being rotated by the mandrel mainly by frictional engagement when the drawing is taking place. Fig. 7 shows a mandrel with a cylindrical end 55 for making a tube with a cylindrical end for jointing to the head, the tube being re-worked to eliminate torsional strain on a suitable mandrel as before. To make the tube end as in Fig. 11 with a thicker cylindrical part at its end and tapering to thickness to the normal section the die 69, Fig. 12, is used with two opposite conical sections 69, 70 and a cylindrical part 71. This section is also reworked similarly to eliminate torsion strain. To make a tube tapering in one direction and then changing to taper in the reverse direction i.e. forming a waist the ball cage 38, Fig. 15, is caused to advance, relatively, to the right during drawing and then reverse, moving to the left this being done by causing the screw threads 86 to change at 87 to slope the other way thus acting as cam grooves for the cam studs 89 instead of the usual nut. This double tapering tube is also reworked on a mandrel 92, Fig. 17, secured to the chuck 15 the mandrel being in two parts, the part 96 being screwed into the part 92. To form a tube with a waist with thickened wall at the waist, the apparatus of Fig. 15 is used but the mandrel is concave at 101, Fig. 20, near the point, and this tube is finished on a mandrel and die tube shown in Fig. 21. Chucks.-The tube is entered into the sleeve 12 of a chuck the tapered plug lying in the mouth of the tube then being screwed forward by hand wheel 20 to push jaws 15 out against the tube to clamp it against the sleeve 12.
