Title: Method of and means for charging carbon disulphide furnaces
IPC: C01B31/26
Filed: 1925-07-02
Abstract: Carbonaceous material is heated to 1000 to 1200 DEG  C. in order completely to de-gasify it before it is fed, with exclusion of air, to a carbon bisulphide furnace.  Preferably the furnace is of the shaft type which may be electrically or otherwise heated, and the carbonaceous material is degasified while passing through a separate electric furnace provided with electrodes, the upper of which is movable.  This preliminary furnace is disposed above the charging opening of the carbon bisulphide furnace proper, the glowing carbon being fed, with exclusion of air, in such a manner that the carbon bisulphide vapours produced do not pass through the preliminary furnace.

Title: Improvements in and relating to circuit-failure indicator systems
IPC: B60Q1/38
Filed: 1953-06-19
Abstract: 772,655. Lamp failure alarms and warning- devices. LEWTHWAITE, R. W. Sept. 17, 1954 [June 19, 1953], No. 17115/53. Class 118 (2). [Also in Group XXXVII] A lamp-failure warning device for vehicles comprises a thermal switch and indicator lamp unit 10 inserted as shown in series with the vehicle battery 12, switch 14 and five lamps 16, which latter comprise two side lamps, two tail lamps and rear number plate lamp. A heater element 18 is carried on a bi-metal strip 24 having a contact 22 co-operating with contact 26 on another bi-metal strip 28 arranged to compensate for ambient temperature changes. On closing switch 14 the lamps 16 and an indicator lamp 30 light up but the current through the five lamps 16 is sufficient to cause the contacts 22 and 26 to open, thereby extinguishing lamp 30. If one of the lamps 16 fails the current through heater 18 is no longer sufficient to maintain contacts 22 and 26 open and the indicator lamp 30 is therefore lit. This, however, restores the current through heater 18 to that taken by five lamps and thus the contacts 22 and 26 are re-opened and the cycle repeats, causing lamp 30 to flash. If more than one lamp 16 fails, or the fuse 20 blows, the contacts 22, 26 remain closed and lamp 30 lights steadily. A constructional arrangement is described with respect to Figs. 2 and 3 (not shown). This provides a coloured lamp on the dashboard and means to adjust the thermal switch (see Group XXXVII) so that it operates when five lamps are in circuit but not when only four are in circuit. The lamps 16 may be of different ratings, in which case the lamp 30 may flash or light steadily when one lamp fails dependent upon the relative power ratings of lamp 30 and the lamp that fails.

Title: Gears
IPC: F16H55/12
Filed: 1974-04-18
Abstract: 1448059 Toothed gearing VICKERS Ltd 16 April 1975 [18 April 1974] 17150/74 Heading F2Q In epicyclic gearing having a plurality of planet pinions 8 supported by a common carrier 1 in a cantilever arrangement, the composite support members for each pinion are rendered capable of elastic deflection in use, under gear load, and these support members comprise a pillar 2 projecting from a face 1A of the carrier 1, an overhung bearing sleeve 3 about which the pinion 8 can be rotated, and an internal pillar 4 joined by an end diaphragm portion 13 to the sleeve 3, with the pillar 4 held in close abutment to pillar 2 by a bolt 6. The abutting faces of pillars 2 and 4 may be provided with mating serrations, spigots or tapered surfaces. Under the influence of tangential gear load forces, and of radial centrifugal forces, the pillar members 2 and 4 will be subjected to bending stresses, and the abutment faces are located at a central region of minimum bending moment, i.e. at the point of contraflexure of the assembly. The dimensions of a circular recess 11, providing a diaphragm portion 12 of the carrier 1, and the dimensions of a recess 14 in the region of the diaphragm portion 13 of sleeve 3, are chosen such that matched corresponding deflections will occur in those members in response to load forces which also deflect the pillars 2, 4, thereby maintaining parallelism between the axis of the planet pinion 8 and the axes of the mating gears 9, 10. The dimensions of the various members supporting the pinion 8 are also chosen such that their combined centre of mass lies both at the point of contraflexure and also in the transverse plane containing the effective line of action of the gear tooth load forces, thereby minimizing adverse effects on parallelism of purely centrifugal forces. Thickened portions 16, Fig. 1, may be added to the sleeve 3 for this purpose. In another embodiment, Figs. 9, 10, 11, the recesses 11 in carrier 1 are provided with radially-disposed stiffening webs 17, and similar radially-disposed webs 18 are provided as stiffening to the diaphragm 13 between sleeve 3 and pillar 4, thereby offering increased resistance to centrifugal forces without impairing the load-sharing tangential deflection characteristics. The same support means may be employed to support toothed wheels in gear trains other than epicyclic gear assemblies.

Abstract: 956,447. Lathes. ETABLISSEMENTS A. CASENEUVE. May 17, 1960 [May 25, 1959], No. 17316/60. Heading B3T. A device for controlling the cross feed movements of a tool-slide 17, Fig. 3, of a copying lathe comprises a compound feeler 4, 6 the part 6 of which is biased by a torsion spring towards the feeler proper 4. The device is particularly suitable for cutting screw threads in a semi-automatic manner on a lead-screw lathe. A plane templet 25 with a shoulder 28 is used. The portion 6 of the compound feeler is longer than the portion 4 by an amount " d," Fig. 6b. At the commencement of a threadcutting operation the portion 4 of the feeler rides along the templet and the part 6 separates from the portion 4, Fig. 4b. When portion 4 reaches the shoulder 28 the tool-slide is withdrawn, the saddle 15 is then reversed and the feeler moves back over the templet with the extended portion 6, Fig. 6b, controlling the tool 24 which is thus held away from the work to clear the thread. Further traverses are made in a similar manner, using the handle 22 to adjust the depth of cut, until the thread is completed.

Title: Improvements in or relating to machines for making nuts from cold bar-stock
IPC: B21K1/68
Filed: 1926-07-12
Abstract: 261,657. Fries, A. de. July 12, 1926. Nuts.-In automatic machines for making nuts from bar stock in which the shearing off and pressing tool has to make two operations, one cooperating with a chamfering die and the other with a finishing die both on the change slide, during the time the holing punch is making one operation, the shearing off and pressing tool is arranged on a slide separate from and driven independently of the slide carrying the holing punch; the notching-punch may be carried in the same slide as the holing-punch or in a third slide. The holing-punch 6 and notching-punch 7 are on a slide 3, and the shearing off and pressing tool 5 and finishing punch 4 are on another slide 2. The notching-die 12, holing-die 13 and cutting- off bar 14 are on a bridge 11 between the slide 3 and the change slide 8 which carries the chamfering die 9 and burr removing die 10. After the nut 16 is severed from the bar stock 15 by the tool 5 it is pressed by the same tool against the die 9 to form the chamfered face, during which time it is held by the pin 17. The slide 2 then rises slightly and the slide 8 moves to the right bringing the die 10 under the punch 5, which again descends and forces the nut into the hole 18 of the die 10. When the slide 8 moves to the left the punch 4 again descends and forces the nut through the opening 18 in the die 10, thereby removing the burr, the finished nub then dropping through the hole 19 and guide 20. The slide 3 may be carried within the slide 2, but actuated independently thereof.

Abstract: 604,298. Film splicers. VRY, W. C. DE. July 10, 1945, No. 17533. [Class 98 (ii)] A film splicer comprises a base member 11 carrying a die plate 12 provided with film cutting slots 14, upstanding pins 18 centrally disposed on the die plate for engaging in chosen film feed sprocket apertures and an auxiliary die plate 30 fitting removably over these pins and provided with holes for perforating as with a hand punch 33 the film splicing material at points in register with the sprocket apertures of the joined films. The films are held in place by clamping bars 23 which are pivoted on the plate 12 and when in use abut against stops 25. The width of the die plate 12 is approximately twice that of the film to be spliced. When not in use the screwed end 35 punch is passed through a hole 36 in the die plate 30 and screwed into a threaded hole in the main die plate 12. For making a lapped joint the two films are trimmed successively by placing the last whole frame over the four pins 18, clamping the strip, and shearing off the damaged strip portion with a razor blade. The films are them removed and a length of adhesively backed cellulose strip, preferably a transparent ribbon such as " scotch tape " is placed across the centre of the plate 12 and trimmed by shearing it off down the side edges of the plate, the trimmed film ends are placed over this so that the two ends slightly overlap, clamped in position and the free ends of the tape folded over on to the upper surface of the joint. Alternatively the tape is first applied to the upper surface of the clamped films and subsequently folded round them. The joined films are then perforated by punching through the holes 31 in the die plates 30 which is located by the pins 18 and the tape peened down around the sides of the apertures. For making a butt joint each film is trimmed along the transverse centre line of the endmost frame and are joined and perforated as before, the films being placed over the pins 18 so that the ends abut against each other.
