Title: Improvements relating to mechanism for varying the angular relationship of two shafts relatively to a third
IPC: F16H1/00
Filed: 1925-04-06
Abstract: 254,408. Sunbeam Motor Car Co., Ltd., Coatalen, L., and Attwood, S. H. April 6. 1925. Regulating. - Relates to toothed gearing embodying epicyclic elements for varying the angular relationships of two or more driven shafts relatively to a driving-shaft, the driven shafts actuating, respectively, a fuel injector or fuel valve mechanism of an internal-combustion engine or the inlet and exhaust valves, In the form shown in Figs. 1 and 2, either of the two driven shafts may have its angular relationship adjusted, whereas in that shown in Figs. 3 and 4, either one shaft alone or both shafts simultaneously are thus adjusted, a third driven shaft and, if desired, further shafts being adjusted simultaneously with one of the firstmentioned driven shafts; in each form, means for changing the meshing of the wheels provides for the changes in the control of the shafts. In the position shown in Figs. 1 and 2, the driving- wheel a drives continuously a loose axially-slidable idler c, driving directly one driven shaft connected to the wheel d, and driving a second driven shaft connected to the wheel b, concentric and of equal diameter with the loose wheel c, through the wheel d and interengaging wheels e, f swinging on links turning about the centres of the wheels c, d. The links may be adjusted by an operating-handle and locked in any position, when the wheel b is advanced or retarded relatively to the driving-wheel a without affecting the setting of the wheel d. The wheel c may be moved axially to disengage the wheel d and engage the wheel f, when the. wheel d is driven through the wheels f, e, and the wheel b is driven through the wheel f. By adjustment of the links, the setting of the wheel d is changed without affecting the wheel b. Certain of the wheels may differ in diameter. In the position of the parts shown in Figs. 3 and 4, the driving- wheel l drives a loose double wheel m, n which drives one mechanism, connected to the wheel o, through a loose axially-slidable wheel q and drives a second mechanism, connected to a wheel p, through link-supported wheels r, s. Adjustment of the links changes the setting of the wheel p without affecting the wheel o. The wheel q may be shifted to disengage from the wheel n and engage the wheels o, s, when the wheel o is driven through the wheels r, s, and q and the wheel p is driven as before. By adjustment of the links, the setting of both wheels p and o are altered relatively to that of the wheel l. A wheel t driving a third mechanism and, if desired, additional mechanism is driven by the wheel q and changes its setting with that of the wheel o.

Abstract: 756,477. Gating circuits SOC. FRANCAISE RADIO ELECTRIQUE. March 29, 1954 [March 27, 1953], No. 9197/54. Class 40 (6). [Also in Group XIX] A coincidence gate for use in an electronic counting system (see Group XIX) comprises diodes 24<SP>1</SP>-24<SP>3</SP>, each shunted by a resistor 25<SP>1</SP>-25<SP>3</SP>. If one input, e.g. C<SP>1</SP> is at high potential, while the other inputs (D<SP>1</SP>1, D<SP>11</SP>1) are at low potential, conduction occurs through the associated resistor (253) and the other diodes (24<SP>1</SP>, 24<SP>2</SP>) and no appreciable increase in potential appears at output E<SP>1</SP>. When, however, all the input are at high potential, none of the diodes conducts, and such potential is transmitted to the output.

Abstract: 957,327. Hair-curling appliances. N. L. SOLOMON. March 14, 1961 [June 21, 1960], No. 9198/61. Heading A4V. [Also in Division E2] A one-piece, snap-acting hair curl clip comprises a pair of clamping members joined at one end and normally spaced apart throughout their length, a portion of one of the members having a permanent deformation causing flexing and being displaceable in opposite directions with respect to the free end of the member so that the free end of the member is snapped into and out of clamping engagement with the other member. As shown in Figs 1, 2 and 3 a U clip is formed of a resilient strip of spring steel, nylon &c. with spaced arms 22, 24. The arm 22 is slotted at 26 and the part 30 deformed by stretching to provide a snap action when, by finger pressure on the outer ends of the arms, the arms are moved from the open position shown in Fig. 2 to the closed position shown in Fig. 3 and vice versa. In a modification parallel longitudinal slits are formed in the arm, the part between the slits being deformed by crimping or stretching and the closed clip conforms to the shape of the head. The clip shown in Figs. 11, 12, 13 is stamped from a blank 86 to form a finger 88, which is crimped and may be offset to provide greater separation, and an integral band 90 which is slotted at 98, 100 to provide parts 102, 104, 106, 108 the outer parts 104, 106 being deformed to provide the snap action. More than one finger may be formed in the stamping operation and the deformation may consist of depressions stamped in the fingers, or in the band, or of localised cold working causing the part to assume a longitudinal curvature. In a further modification the clip is formed of two parts welded or brazed together, and the clamping members are apertured to aid drying of the hair.

Title: Improvements in or relating to apparatus sensitive to thermal radiation
IPC: G01J5/22
Filed: 1950-03-31
Abstract: 707,270. Detecting radiation from flames or heated bodies. BAILEY METERS & CONTROLS, Ltd. March 31, 1950 [April 2, 1949], No. 9329/52. Divided out of 707,225. Class 40 (3) Apparatus sensitive to thermal radiation comprises a bolometer bridge network and phase sensitive electronic control means which supervises an indicator and/or recorder and is continuously receptive of output voltage from the bridge network with the phase of this voltage in one sense or the other dependent on the presence or absence of radiation. In the embodiments described the bolometer resistance and ambient temperature compensating resistance are constructed and arranged as disclosed in Specification 707,225 and form adjacent arms in the bridge network. The latter is arranged to be balanced corresponding to a condition between presence and absence of operative flame or thermal radiation as explained in the Specification. Flame failure alarm system.-In Fig. 1 the bolometer 6 in the bridge 13 receives radiation from a flame 32 in a furnace enclosure 30 and the firing of a phyratron 45 through the action of a phase discriminator triode 38 occurs to operate an alarm 34 via a relay 33 in the event of flame failure. The phase discriminator triode 38 is in one envelope with a rectifier 39 arranged to produce a reference D.C. voltage E2. Normally i.e. with flame present the output bridge voltage eo is in phase with the anode voltage of phase discriminator triode 38 and under this condition the D.C. voltage E1 across the cathode resistance 48 of this triode is slightly greater than the reference D.C. voltage E2 across the cathode resistances of triode 39 and the difference between E1 and E2 applied to the grid of phyratron 45 is just negative enough to prevent firing. When flame fails eo falls out of phase with the anode voltage of triode 38 so that the anode current becomes less and reduces E1 whereupon the phyratron fires in response to lowered negative grid voltage. Recording the speed and frequency of passing of heated objects and elongation of heated objects.-In Fig. 2 a heated billet 51 moved by table rollers 50 passes in front of the bolometer 6 either towards or away from the mill rolls 52. The phase sensitive apparatus 100 is as shown in detail in Fig. 1 and is receptive of voltage from bridge 13 to energize relay 33<SP>1</SP>, controlling a recording pen 53, when billet 51 is in front of the bolometer 6. The record produced on the revolving chart 54 upon a time basis consists of a series of teeth with each tooth representing the passing of a billet before the bolometer 6. Alternate teeth including the first tooth represent movement of a billet towards the rolls 52 whilst the other teeth represent movement away from the rolls 52. Since the cross section of a billet is reduced by passage through the mill the chart record will give relative information as to the extent of elongation. The feature in Figs. 1 and 2 of comparing voltages El and E2 is also disclosed in Specification 707,226 and is claimed in that Specification.

Title: Spooling machines
IPC: G03C3/02
Filed: 1971-04-15
Abstract: 1387622 Winding, unwinding, splicing webs KODAK Ltd 17 April 1972 [15 April 1971] 9592/71 Heading B8R In a machine for winding, in succession, on to a spool 10 a length of paper web 23, a length of photographic film 42 and a further length of paper web 23, a cutting and splicing station 20 is provided for cutting the web or film after a desired length has been wound and splicing it to the succeeding web or film to be wound, means e.g. a reciprocable carriage 51, serving to retract the film 42 from said station whilst a paper web 23 is being cut and to thereafter overlap the cut web and the film to facilitate splicing thereof. A rotatable cam shaft (72), Fig. 4 (not shown), which trips microswitches (74) controlling valves in a pneumatic actuating circuit controls operation of a rotatable mandrel 66 for receiving the spool 10, web and film supply means, the cutting and splicing means 20 and the retracting means. The paper web 23 is supplied from a roll 24 via a roll spindle tensioning device 25 to pinch rollers (34) (35), Fig. 3 (not shown), which pull the web past braking rollers (36) (37) and feed it into a slot in the spool 10, the web being provided with tapered portions spaced along its length to fit this slot. The spool is positioned between axially movable mandrel members 66 by a load arm 68. A guide (64) is then pivoted to temporarily hold the web against the spool which is then rotated. The next taper on the feeding web 23 is sensed by microswitches 27, 31 which stop the winding operation so that the web is correctly positioned beneath a knife 52 at the cutting and splicing station. The film is supplied from a roll 41 via a tensioning device 44 to a vacuum feed drum 46 at which photographic frame numbers may be exposed on to the film edges by a printer 47. The film 42 then passes over the carriage 51 on which it is temporarily held by eccentric discs 53. This carriage is retracted to move the film 42 from knife 52 while it descends to sever the paper web then the carriage is advanced so that the film overlaps the cut web, a blower 89 lifting the web to assist in the overlapping. Next a paster tape held on a suction arm 62 is applied to the overlap to splice web to film, the tape, fed from a roll 58 by a reciprocable carriage 60, being cut by a knife 61 and held on the arm 6 until required. Winding is then continued until a desired length of film has been wound, e.g. as sensed by an unspecified measuring device, a further cutting and splicing operation then being carried out to splice a final length of web to the film. Finally this web is wound on to the spool 10, the remainder being cut off at the next taper point. The spool is then removed by an unload arm 69. A further tape is applied manually to keep the roll lightly wound on the spool. Sensors may detect any malfunction of the machine and halt its operation.

Title: Improvements in or relating to swaging or forging machines
IPC: B21J7/14
Filed: 1953-04-09
Abstract: 768,834. Forging machines. APPEL, G. H. April 9, 1953, No. 9617/53. Class 83 (4). A high - speed swaging machine for radially swaging a rotating and axially moving workpiece 14, comprises at least one pair of opposed radial tools 40 which embrace the workpiece, each tool being actuated by oppositely moving transversely reciprocating members 37, 38 whereby transverse components of force are balanced and only radial forces are transmitted to the tools. The swaging machine comprises a stationary housing 4 having an orifice for receiving the workpiece 14 and a plurality of radiallyreciprocating members 13, Fig. 5, carrying tools 40 which engage the workpiece, actuated by members 17 through eccentric rods 37, 38 which are reciprocated substantially transversely of their respective hammers by eccentrics 35 on shafts 28 journalled in the housing and driven in unison with the workpiece rotating means. The shafts 28, Fig. 6, carry pinions 30 meshing with a central gear 31 driven from the main gear-box 6, Fig. 1, of the machine. The tools 40 fit into recesses 42 of the hammers and are biased inwardly by compression springs 43 so that they are always in engagement with the workpiece. The eccentric rods 37, 38 reciprocate V-blocks 17 having inner V-shaped surfaces 21, engaging rollers 23 which react against the V-shaped ends 22 of the reciprocating members 13, and outer V-shaped surfaces 20 engaging rollers 27 which react against V-shaped surfaces 26 on stationary backing blocks 24 adjustably mounted in slots 25 of the housing. Each V-block is formed as three separate juxtaposed parts 17, 18, 19, Fig. 6, the outer parts 17, 19 being connected by eccentric rods 38 to outer eccentrics 33, 35 on one shaft 28 and the central part 18 of the V-block being connected by an eccentric rod 37 to the central eccentric 34 of an adjacent shaft 28. The adjacent shafts are so driven that the outer parts 17, 19 of each V-block always move in the opposite direction to the central part 18. The rollers 23, 27 are also each formed in three separate parts 60, 61, 62 connected together by a common spring passing through a central bore in each part, Fig. 10 (not shown). The backing blocks 24 are adjusted by wedges 44, Fig. 7, connected through springs 58, 59 to screwed shafts 48 carrying internally threaded worm wheels 51 meshing with worms 53 which are connected to bevel pinions 54 meshing with a central crown wheel 55 which is driven, when desired, from the main gear-box 6. Workpieces whose diameter varies along their length may thus be swaged. The gear-box 6 is driven by V-belts from an electric motor 5, Fig. 1, and has an output shaft 8 connected to a second gear-box 9 driving a lead screw which moves a saddle 3 carrying a chuck 7 for the workpiece 14. The chuck is rotated continuously during the movement of the saddle by a pinion 12 meshing with a rack 11. In other embodiments the V-blocks 20 are replaced by toggle links 71, Figs. 11, 12 (not shown). The workpiece may be swaged hot or cold.
