Abstract: 1,075,425. Rope-guides. COAL INDUSTRY (PATENTS) Ltd. May 15, 1964 [May 17, 1963], No. 19689/63. Heading B7L. A device for retaining a rope on a pulley comprises a retainer 2 pivoted at 3 to support 4 and a striker 5, the edges of which project beyond those of the retainer 2, pivoted at 8 to retainer 2, a fixed plate 6 co-operating with abutments 7 on striker 5 normally to prevent retainer 2 from rotating about pivot 3. However, when an attachment fixed to the rope engages striker 5, the latter is rotated about pivot 8 to move abutments 7 clear of plate 6 so that when the attachment subsequently engages retainer 2 the retainer is able to pivot about pivot 3 whereby the attachment can pass. Springs or gravity return striker 5 and retainer 2 to their normal position.

Title: Improvements in or relating to the production of luminous masses or compounds
IPC: C09K11/56
Filed: 1933-07-13
Abstract: Luminous or phosphorescent materials, in a sufficiently finely divided state for incorporation, without grinding, in a paint medium, are formed, by a process including one furnacing only, from the carbonates of strontium, calcium, magnesium, lithium and rubidium, together with a small amount of a "phosphorogen" and a "luminophore" or flux.  As "phosphorogens," which are directly responsible for the phosphorescence, may be used nitrates of bismuth, uranium, vanadium, rubidium or erbium, sulphate of copper or acetate of lead, while the sulphates of sodium, potassium, lithium, cadmium, magnesium and manganese, sodium carbonate or chloride, and magnesium chloride may be used as "luminophores." The carbonates of strontium, calcium and magnesium are dissolved in a minimum quantity of dilute nitric or hydrochloric acid, and the "phosphorogens" added, together with the "luminophores" if these latter can be precipitated by hydrogen sulphide.  The mixture is heated, and hydrogen sulphide passed, to precipitate a compound sulphide, which is dried and ground.  The carbonates of lithium and rubidium are now added, together with the "luminophores," if not already present, and about 1 per cent by weight of carbonaceous material such as starch.  The composition is furnaced in a closed crucible for about 1--1\ba1/2\be hours at 600--900 DEG  C., and a strongly phosphorescent and finely divided product is obtained which can be incorporated, without grinding, in such media as linseed oil or solutions of nitrocellulose or cellulose acetate.  Other ingredients such as resins, zinc sulphide, zinc sulphate, barium sulphate and calcium carbonate may be included in the paint.

Abstract: 1,223,376. Constant tension winches. GEWERKSCHAFT EISENHUTTE WESTFALIA. 18 April, 1969 [19 Oct., 1968], No. 19954/69. Heading B8B. In the drive to a winch drum, a control means to ensure a pre-set traction force for an associated winch cable comprises a mechanical load-sensing device including a gear member transmitting torgue between the drive means and the drum shaft, the gear member being mounted on a shaft 37 which eccentrically carries a rotatable element 33 operatively coupled to a switch adapted to actuate the drive means. The gear member comprises a pair of coaxial integral gears 38, 38<SP>1</SP> of different diameter and transmitting the drive between gears 32, 39, whereupon the resultant force in the gear member causes the element 33 carrying the shaft 37 to be displaced about a shaft 17, against spring bias, to operate the drive motor switch. The latter is set to operate at a certain traction force on the winch drums whereby that force is substantially maintained by the switching action which is hydraulically damped. The winch drum which is provided with a hand brake, is coupled to its drive shaft by a clutch, and the drive shaft may extend beyond the gear housing and winch drum to carry further winding drums. When the control means is used in a multispeed gear arrangement, it is by-passed in all but the lower or lowest speed gear arrangement.

[Class 142 (iv).] In beaming yarn for dyeing, bleaching, or other wet treatment by cross winding the yarn on a beam with the aid of a reciprocating comb, increased density of yarn at the ends of the yarn package is produced by reducing the traverse of the thread passing at these parts from the comb to the beam. In the machine construction shown in Fig. 2, the traverse of the end threads is reduced by an overhanging wire member 32 on a loosely mounted sleeve 33, which is given a shorter stroke than the comb 3, by means of adjustable connections 34, 35 from the comb bar 4. Alternatively, fixed members 32<a> 32<b>, Fig. 6 having depending curved portions may be provided at each side of the machine to gather the end threads at each stroke of the comb. The comb bar 4 is reciprocated by a cam 5. Specifications 17296/92, 7225/01, [both in Class 142], and 382,593 are referred to.

Abstract: 1,072,939. Axial-flow compressors; turbines. SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 12, 1965 [May 12, 1964], No.20063/65. Headings F1C and F1T. [Also in Division G1] Vibration or deformation of electrically conductive rotor blades of an axial-flow compressor or gas turbine is sensed and indicated by means comprising a graphite rod (5) disposed with its end adjacent the path of the leading edges of the blades. If a blade vibrates sufficiently to come into contact with the graphite rod, it completes an electrical circuit to trigger a bi-stable electronic circuit to produce a continuous light or acoustic signal. Subsequently, the bi-stable circuit can be re-set manually by pressing a button. Abrasion of the graphite rod by the vibrating blade produces a graphite marking on the blade which enables the latter to be identified. After the machine has been stopped, the amount of abrasion of the graphite rod can be measured to determine the amplitude of vibration. The graphite rod (5) is carried by an insulating sheath (6) adjustably supported by a member (3) which is screwed into a hole in the compressor casing in place of a plug which normally closes the hole.
