Title: Method of automatically forming cast or moulded products with inserts therein
IPC: B29C45/14
Filed: 1955-10-05
Abstract: 786,920. Moulding travellers for ring spinning &c. frames. COATS, Ltd., J. & P. Oct. 5, 1955 [May 3, 1955], No. 28349/55. Class 87(2). [Also in Group IX] A traveller for ring spinning and twisting frames, in the form of an article 10, Fig. 2, having a small hooked end 11 and a large hooked end 12, the member being made of plastic material and having embedded in the end 12 a metallic reinforcing insert 13, is made as follows: A metallic strand 15 is unwound from a spool 16, Fig. 1, gripped by a device 24, 25, and its end 13 is disposed within the mould cavity, the part 13<SP>1</SP> being clamped in a groove formed in the meeting faces of a two-part mould 17, 17, Fig. 3. An ejector rod 22 also is clamped in a groove in the meeting faces, its end extending into a gate-forming recess 21<SP>1</SP>. Plastic material is then injected from a nozzle 33 into the mould cavity 18 to form the moulded article 10 having the end of the metallic strand embedded therein, and to form a gate 21. The mould then opens, Fig. 3, the gripping device 24, 25, is released and the rod 22 and strand 15 are moved downwardly (the strand being moved by a gripper 26) to transfer the moulded article and gate to a trimming station (see Figs. 2 and 3) where tools 30 cut the strand at the surface of the article and also cut away the gate. The article is thus freed and falls into a receptacle. Before the tools 30 separate the rod 22 is raised to strip it from the cut-off gate which falls into another receptacle. The gripper 26 then raises the strand to the moulding position, Fig. 1, rod 22 rising also. The moulding and trimming operations are then repeated. Specifications 565,848, 627,157, 627,370, 627,371, 627,372, 627,373, 627,374 and 627,375 [all in Group IX] are referred to.

Title: Improvements in and relating to systems of control for dynamoelectric machines
IPC: B60L15/04
Filed: 1923-11-10
Abstract: 216,050. British Thomson-Houston Co., Ltd., (General Electric Co.). Nov. 10, 1923. Regenerative systems.-In an arrangement for regenerating electric braking of a group of motors such as are employed for propelling vehicles, two of the machines are used as exciters and the remainder as braking generators. Each of the armatures of the exciter machines A<5>, A<6> is connected in a local circuit with the field windings of half the braking machines, the exciter A<5> supplying the fields F<1>, F<2> and the exciter A<5> supplying the fields F<3>, F<4>. Each exciter armature further supplies the field winding of the other exciter. A variable resistance R<3> forms a common part of the two excitation circuits, and a junction containing resistances R<10>, R<11> acts to equalize the currents in the exciter fields F<5>, F<6>. The braking circuit runs through the armatures of the remaining motors, and through a resistance R<8> included in a common part of the excitation circuits, whereby the excitation is made to vary inversely with the braking current for stabilizing purposes. In a modified arrangement the braking machines are in two parallel groups each connected to a separate stabilizing resistance, and the two exciter machines are arranged so that each armature excites its own field subject to the action of an equalizing connection. Specification 169,208 is referred to.

[Class 98 (i)] In order to increase the durability of a layer for use with metal-vapour discharge tubes, consisting of red-fluorescent rhodamine dispersed in a binding medium such as a synthetic resin, the harmful radiations which lie within the range of the rhodamine absorption band in the visible spectrum are partly absorbed by a superimposed orange-coloured filter layer which transmits red light. The rhodamine may be dispersed in a condensation product obtained from symmetrical dimethylglycol and citric acid, or from glycerine and phthalic or citric acid, and is applied to a support by means of acetone. The dispersion may contain a small quantity of lead chromate to assist fluorescence. The filter overlayer may consist of Methasolaurine A.S., or Orange G, or Sudan Orange G, dispersed in the same condensation products, and applied by means of acetone. Reference is made to the use of the screens as signals on roads illuminated by metal-vapour discharge tubes, such as mercuryvapour, or sodium-vapour lamps ; and curves are given showing the spectral absorption band of rhodamine and the transmission band of Methasolaurine A.S.

Tobacco placed in the trough 6 is supported by a back-plate 7, engaging the band 5 by means of pins and held at its upper end in slots 11 in a pair of carriages 12. The tobacco is fed forward uniformly to a picking cylinder 1 by driving the roller 8 adjacent to this cylinder, the plate 7 being simultaneously moved by the action of cords 15 and weights 14 which draw the carriages 12 along rails 13. A reserve plate 23 and carriage 24 are. provided in the trough 6. The trough, with all its fittings, is supported by a frame 10, having projections slidably engaging grooves in a bracket 29.

Abstract: 1,170,382. Gas turbine engines -bearings. ROLLS-ROYCE Ltd. June 12, 1968 [June 23, 1967], No.29226/67. Heading F1G. [Also in Division F2] The shaft 15 of the high pressure compressor of a gas turbine engine is rotatably mounted by means of ball bearings 18 and 19 carried on struts 20 and 21 attached to the engine casing, and the shaft 13 of the low pressure compressor is mounted on strut 20 and within the shaft 15 by ball bearings 30 and 22. The outer race 24 of the bearing 22 is axially slidably mounted in a sleeve 27 which itself is supported by a radially resilient sleeve 28. Annular spring washers 36 impart axial load to the outer race 24 which is transmitted via the balls, inner race 23 and the shoulder 26 to the shaft 13 which in turn transmits the thrust to the bearing 30. The spring washers 36 simultaneously impart opposite axial loading on the inner race 56 of the bearing 18, the spring load acting through sleeve 28 and shaft 15. The outer race 47 of bearing 19 is axially slidably mounted in the strut 21 and a spring washer 53 is provided to axially load the race. The thrust is transmitted via the balls 48, inner race 46 and the shoulder 49 to the shaft 15 and thus preloads the bearing 18. In place of the spring washers, helical springs or flexible containers having in them fluid under pressure may be used to load the bearings. The invention is particularly applicable to engines having a plurality of concentric relatively rotatable shafts, and the Specification describes a by-pass engine for use in a VTOL aircraft.

Title: Improvements in or relating to reducing the lustre of cellulose ester and ether materials
IPC: D06M13/02
Filed: 1932-10-19
Abstract: Cellulose-ester and -ether materials are delustred by subjecting them to the action of hot aqueous media or moist steam in the presence of naphthalene or an alkyl or ether derivative thereof, e.g. a - and b -methyl naphthalene, and b -naphthol methyl ether.  The treatment may take only a few seconds, so that the materials may be treated continuously, for example, on a jig. The naphthalene or the like may be dispersed in the hot aqueous medium by means of soap, turkey red oil, or other dispersing agents such as those described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 15 (ii)].  A solvent such as xylene, or a halogen hydrocarbon may be present. Alternatively, the materials may be first impregnated with the naphthalene or the like, as by padding, using a relatively concentrated dispersion, and thereafter passed through hot or boiling water.  In a modification, the materials are printed with a dispersion of the naphthalene or the like, and then subjected to the action of the hot aqueous media, whereby pattern effects are obtained.  The delustring baths may contain substances adapted to modify the action of the bath, as described, for example, in Specification 260,312, [Class 2 (ii)].  The following examples are given: (1) Cellulose acetate fabric is passed through a dispersion obtained by heating naphthalene with xylene and turkey red oil and pouring into water.  (2) Cellulose acetate fabric is passed through a dispersion obtained by heating b -naphthol methyl ether with turkey red oil and pouring into soap solution.  (3) Cellulose acetate fabric is padded with a dispersion obtained by heating naphthalene with xylene and turkey red oil and pouring into water, rolled up, and allowed to stand overnight.  The fabric is then passed through a tank of water at about 98 DEG  C.  Specifications 165,164, 266,777, [both in Class 2 (ii)], and 409,276 also are referred to.
