Title: An improved method of and means for finishing gears
IPC: B23F19/06
Filed: 1960-06-07
Abstract: 952,745. Gear-finishing. J. A. MILLS. March 15, 1961 [June 7, 1960], No. 19902/60. Heading B3K. A gear-shaving machine comprises means for relatively traversing the gear 8a and tool 9a at at least two speeds for initial and final cutting strokes. A reversible motor 10 mounted on a knee 7a rotates a screw 9 for traversing the work-table 8 as in Specification 943,428 and a screw 7c for feeding the knee upwardly as in Specification 952,601. Two rotational speeds for the screw 7c are provided by electromagnetic clutches 18, 21. When either clutch is engaged, a control disc 26 is also rotated to actuate switches 48. The speeds for the screw 9 are obtained by reversing clutches 35b, 36b controlled by a switch operated by dogs on a disc 46, and clutches 41b, 42b controlled by the disc 26. A second dog on the disc 46 operates an over-travel limit switch. The switch controlling the reversing-clutches also energizes the clutch 18 to initiate a slow upfeed. As an example of operation, the table is fed upwardly while a traverse rate of 0.018 inch per gear revolution is maintained for four passes, the traverse rate then being lowered to 0.010 inch per revolution for two passes without upfeed.

Patent GB-257086-A (GB)
Title: Improvements in or relating to electric switches and switch-gear
IPC: H02P1/04
Filed: 1925-08-08
Abstract: 257,086. Switchgear & Cowans, Ltd., and Neep, G. H. Aug. 8, 1925. Cut-out arrangements. - Relates to arrangements comprising master switches and main switches for controlling under safe conditions apparatus such as the motors of portable coalcutting machines, where the main switches Y, Z are situated in a gate-end box 2 and the master switch V is situated close to the motor 34. According to the invention, relays 3, 4 one of which is energized when the master switch is moved to its first position 35 or 36, make a connection back through the trailing cable 37, which allows another relay 33 to be energized by moving the master switch to its second position 39 or 40 the relay 33 completing a local circuit at the gate-end whereby the main switch closing coils Y or Z are finally energized. The closure of the main switch is thus made contingent upon continuity of the main and earthing conductors in the cable 37. Overload and leakage protection is provided by series and balance coils 28, 29, 30. In the arrangement shown, the relays 3, 4 serve to select the direction of running. Alternatively, two or more relays acting in a similar manner may be employed to switch current to a motor in stages or to a number of machines in desired order. Specification 209,831 is referred to.

A tear tape (25) may extend from the longitudinal seam of the tube around the back and two sides of the further tube. The tubular body may have a cut out portion at the front corresponding to the inner frame of a flip-top carton. The front portion of the tube is torn open against the edge of the cut-away portion. The packet may be used as it is or be inserted in a flip-top carton. The tubular body, and tube(s) and cap are made from card or paper respectively laminated with aluminium foil. The packet may be formed by forming the tubular body about a mandrel, attaching the cap, withdrawing the mandrel, and securing the foil tube. Alternatively if the two foil tubes are used they are secured to the tubular body and one tube closed before withdrawal of the mandrel.

Title: Improvements in or relating to clutch controlled gearing
IPC: B23Q35/32
Filed: 1923-08-09
Abstract: 225,598. Burnett, A. S., Collins, T., and Shaw & Co., Ltd., F. Aug. 9, 1923. Milling-machines.-In a plano-milling machine of the kind in which a tracer moves over a templet, the movements of the tool and work are effected through clutch mechanism controlled by power-driven means, electrically-controlled means transmitting the power to the clutch. A double clutch 16, Figs. 4 and 5, is operated by a T- shaped lever 17, which is rocked by means of two pairs of toggles 26, 27. which are reciprocated rapidly by means of a power-driven cam shaft 22 and a spring 23. The toggles are normally kept extended by springs 29, and each toggle reciprocates in guides 25. The effect of breaking one of the toggles is to strike up one of the arms of the lever 17, and so thrust the clutch to one side or the other. The free ends of the toggles are for this purpose stopped by a hit-and-miss device, consisting of pawls or stops 30, 31 drawn into position by solenoids 32, 33. Neutralizing stops 43 are provided to break both toggles partially at the same time to bring the clutch 16 to midposition. The templet is carried on a reciprocating table while the milling-cutter and tracer are mounted on a vertical slide. The tracer 35, Fig. 3, acts through compound levers 37 upon a switch arm 34. In the extreme positions of the switch, the solenoids 32, 33 are energized respectively. In the middle position, a solenoid 42 is energized to bring the neutralizing stops 43 into action.

In a method of sheathing a stranded metal core with a metal strip, the strip is folded around the core with the longitudinal edges of the strip bent away from the core and the bent edges of the strip are trimmed prior to arc welding them together. In a machine for making the inner conductor of a submarine cable, an endless conveyer 3 draws a core 1 and a copper strip 5 from braked reels 2, 6. Rollers 7 fold the strip 5 around the core 1 and form the bent edges which are trimmed by a rotary milling cutter 8 having a vacuum extractor 25 for swarf. The conductor is pulled through a bore in a guide 9 formed of hardened steel members 11, 12 bolted together and having coolant passages 22, 23. A passage 15 in the guide 8 provides access for an argonshielded arc welding head having a shroud 16. The bent edges of the strip 5 are guided in a slot 20 of the guide which has passages 17, 18 feeding additional argon to the welding point. One or more additional welding heads 29 are provided for use when welding is commenced or to reweld unsatisfactory portions of the welded seam. A second trimmer may be located between the welding heads.

Title: Treatment of cellulose fibres and fabrics
IPC: D06M16/00
Filed: 1932-07-23
Abstract: Cellulose, in its raw state or in the form of threads, fabrics, fishing-nets, or the like, is uniformly acetylated so that the increase in weight of the cellulose is not more than 18 per cent, by means of an acetylating mixture containing up to 0,25 per cent of perchloric acid, or a salt thereof, 5-10 per cent of acetic anhydride, with the residue of a diluent organic liquid, there being present not more than 1,5 parts of acetic anhydride to each part of cellulose.  Uniformity of acetylation is secured by agitation and by maintaining the temperature of the mixture uniform throughout the operation.  As a preliminary treatment the cellulose may be subjected to boiling in water or in alkali solutions to increase its reactivity, and/or it may be steeped in acetic acid or another liquid in which water is soluble, e.g. acetone.  In an example, alkali boiled cotton yarn is dried to about 2 per cent of moisture, and steeped in glacial acetic acid. The cotton is then centrifuged and introduced into a mixture consisting of 8-10 per cent of acetic anhydride, 0,04 per cent of perchloric acid, and the residue glacial acetic acid, 15 parts of the mixture being used for each part of dry cotton.  After 4 hours, during which time the mixture is agitated and kept at a uniform temperature, the cotton, which has increased in weight by about 10 per cent, is separated, washed, and dried.  The cotton is rendered immune to deterioration by destructive organisms without substantial interference with the normal textile properties, such as textile strength, of the material.  The Provisional Specification includes processes of esterification other than acetylation, and mentions butyrylation.
