Abstract: 183.169. Cullin, J. F. Feb. 16. 1921. Apparatus for making; insulation. -A winder for armature coils of electric machines, shown in side and end elevations in Figs. 1 and 4 respectively and in plan in Fig. 5, consists of two winding-plates 30, 32 one of which has a hub 37 with inclined edges which force the coil sides at the same angle as that between the armature slots into which they fit, radial ribs 38 being also provided on one or both plates to cause the strands at the ends of the coil to lie in a single plane. Fig. 8 shows a section through the winding plates and the sides of the coil. The rotary shaft 1 carries a member 11 having three fingers 13, 14, 15 between which are pivoted at 16 elbow levers A, B having shearing surfaces 21, 24 for co-operation with shearing edges on the fingers 14, 15 for severing the finished coil. The levers are normally held by a spring 46 in the position shown in Figs. 1 and 5 and are moved forward to sever the coil by a sliding cone 5 and operating fork 8. The supply of wire 20, Fig. 5, passes over inclined faces 17, Fig. 1, on the fingers 14, 15 and a notch 23 on the lever A so that when the lever is swung it cuts the wire against the shearing edge 18 of the finger 14. At the same time the edge 24 of the member B, Fig. 5, cuts the wire against the edge 19 of the finger 15. To wind a coil, the wire is introduced at 56 between the plates 30, 32 and the shaft is turned. The sides of the coil are formed in two layers 58, 60, Fig. 8, and its ends in one layer between the ribs 38, 52, Fig. 1. A clamp 40, Fig. 4 is put around the side of the coil and the fork 8 is moved to cause the members A, B to shear the end 42 of the finished coil and the supply wire at 43. The end 41 springs out, as shown in dotted lines, and the end 44, Fig. 5 is bent into a space between the lever B and the finger 14. The latch 32 is unhooked from the pin 31 so as to free the plate 32 and allow removal of the coil. After removal, the sides of the coil are wrapped with paper which retains the insulating material into which the coil is dipped. For the next coil, the members A, B are swung back by withdrawal of the cone 9 and after the plate 32 has been replaced and the shaft set in motion, the operator has only to guide the supply wire into the opening at 17 for shearing at the end of the wind.

Title: Improvements in or relating to the cycles of the working fluid in internal combustion engines and turbines
IPC: F02B33/44
Filed: 1934-02-19
Abstract: 433,630. Gas turbines. RODDAM, G., 10, New North Road, Bourda, Georgetown, Demerara, British Guiana. Feb. 19, 1934, No. 5398. Drawings to Specification. [Class 110 (iii)] In an internal-combustion engine and turbine plant, the working fluid is first compressed isothermally and heated by regeneration from the exhaust gases of the plant and is then admitted to the cylinder of an internal-combustion engine, where adiabatic compression, combustion, and partial adiabatic expansion take place, the exhaust from the engine passing to the turbine to complete the adiabatic expansion before exhausting to the regenerator. The fuel used may be solid, liquid, or gaseous, and the working fluid is preferably air, but may be air diluted with cooled exhaust gases to reduce the combustion temperature ; the ratio of adiabatic compression is chosen to produce ignition by the heat of compression, combustion taking place at constant volume. The isothermal compression preferably takes place in a turbo-compressor driven by the turbine which is mechanically independent of the engine, the latter taking the whole of the external load. The fuel supply to the engine is controlled by a governor driven by the engine, and the speed of the turbine depends only on the pressure and temperature of the exhaust from the engine, which in turn depends on the load, so that the ratio of isothermal compression increases with the load. The turbine, may have more than one stage, in which case the high-pressure turbine may drive the turbo-compressor while the lowpressure turbine may share the external load with the engine.

Abstract: 1,128,851. Ion microscopes; particle spectrometers. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, and CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 8 Feb., 1966 [9 Feb., 1965], No. 5551/66. Heading H1D. In an ionic microanalyzer in which an image of the sample a b is derived under bombardment by ions or neutral particles, the emitted ions are focused to a first cross-over C 0  by a lens L, are deflected by a magnetic double prism, as shown, on to an electrostatic mirror 2, 3, 4 in such a way as to form a second crossover C located in front of the mirror, and are then, after reflection from the mirror, deflected again by the magnetic prism to form a final cross-over C 1  before passage to an image converter. An aperture or slit diaphragm 5 filters the ions after the first deflection according to momentum while the mirror acts as an energy filter. The second deflection serves only to direct the ions on to the imaging ion optical system. A selection slit at the final cross-over C 1  eliminates parasitic ions emitted by the mirror electrode 4. A stigmator 17 is provided at the final cross-over C 1  and stigmators may also be provided at the cross-overs C 0  and C. The mirror is designed to act as a spherical convex mirror M with its centre located at the cross-over C and its apex S at a virtual image stigmatic point at the centre of the prism O. The mirror electrode 4 which collects the ions of excessive energy is irradiated through a quartz window (14, Fig. 7, not shown) by a lamp (15) so as to be maintained at a temperature preventing contamination.

Abstract: 1,147,463. Sewing machines. GENERAL AUTOMATED MACHINERY CORP. 16 May, 1966 [28 May, 1965], No. 5603/68. Divided out of 1147462. Heading D1G. A sewing mache comprises a presser foot formed with a recess, a knife blade fixed in the recess, and means slidably mounted in the recess for projection therefrom to seize a thread, and for retraction to sever the seized thread at the knife blade. The presser foot body 190 is formed with a recess 191 in which is fixed a knife blade 204, and which slidably supports a thread-retaining blade 192 formed in one edge with a notch 196, and thread-seizing blades 193, 194 formed with respective thread-seizing notches 197, 198 opposing notch 196. A lever 200, pivoted on body 190, has one end 199 engaged with the blades 192, 193, 194, and its other end is rigid with an upstanding rod 201. The upper end of the latter abuts the depending piston rod of a pneumatic jack (189). During a sewing operation said piston rod is extended to turn lever 200 clockwise against the bias of a spring 203 for retracting the blades 192, 193, 194 within the body 190. The presser bar 8 is connected by a linkage to the piston rod of a pneumatic jack (9). To commence a sewing operation, a workpiece is pressed against a hinged plate 11 which thereby closes a passage 12 formed in a fixed block 50 and connected to an air presser line 12. Pressure in the latter thereby rises to close a diaphragm-operated switch, whereby jacks (9) and (189) are actuated to engage the driving clutch, to lower the presser bar 8 and to raise the blades 192, 193, 194. At the conclusion of the sewing operation plate 11 is feed and said switch is thereby opened. The driving clutch is thus disengaged, while the presser bar 8 is raised, and the blades 192, 193, 194 are lowered to trap the stitch chain within the notches 197, 198. When the blades 192, 193, 194 are raised at the commencement of the next sewing operation, the stitch chain is 'severed by the knife blade 204. Compressed air is delivered by a tube 13 to the recess 191 for cooling the needle. A toothed element (213), pivoted to a fixed bar (211), is spring-biased against the work-supporting surface at the rear of the presser foot. A guide roller (216) is carried by an angularlyadjustable arm (215) secured to the worksupporting surface adjacent element (213).

Title: Phase insensitive synchronously tuned filter
Inventor: RINGOEN RICHARD M
IPC: H03H19/00
Filed: 1956-02-24
Abstract: 809,550. Changing wave shape. COLLINS RADIO CO. Feb. 24, 1956, No. 5872/56. Class 38 (2). [Also in Groups XL (b) and XL (c)] Relates to a synchronous filter of the type in which an input A.C. signal 10, Fig. 2A, is applied through a high resistance 13a, Fig. 4, alternately to two capacitors 18a, 19a by means of a switch 17a operating cyclically at a frequency f such that a square wave 28, Fig. 2C of fundamental frequency f is produced at the common contact of the switch 17a by an input sinusoidal signal of frequency f ; when the frequency of the input signal differs from f, the charges on the two capacitors tend to be equal and the arrangement functions in effect as a high-Q narrow-band filter, e.g. when the frequency f is 24 c/s the effective band-pass is 0.03 and the Q is 750. With such a filter the amplitude of the output waveform 28, Fig. 2C, is proportional to cos # where # is the phase difference between the switching cycle, Fig. 2B, and the input waveform 10 and according to the present invention an output signal of amplitude independent of # is obtained by using a second synchronous filter 13b, 17b, 18b, 19b, whose switch 17b is operated in phase quadrature with the switch 17a, the input signal being applied in parallel to both filters and the outputs therefrom being combined in a summing network comprising two cathode followers 42, 43. As shown in Fig. 4, each switch is of the single-pole double-throw type and is actuated by an operating coil, the two coils 26a, 26b being energized in phase quadrature from a two-phase generator 64 operating at the frequency f. In a modification, Fig. 5, each switch comprises a fixed contact 114 which engages two arcuate contacts 121, 122, insulatingly mounted on a rotating earthed shaft 163, the two storage capacitors 118, 119 being connected between the shaft and the contacts 121, 122 and the two sets of contacts 121a, 122a and 121b, 122b being relatively displaced by 90 degrees. When the invention is applied to a conical scan radio direction-finder, the shaft 63 of the generator 64, Fig. 4, or the shaft 163, Fig. 5, of the rotary switches is rotated synchronously with the spin component of the scan. If electronic switches are employed, the arrangement may be used for filtering radio frequency signals.

Abstract: 214,208. Dondelinger, F. April 14, 1923, [Convention date]. Vibration-dampers; dash-pots. - In shockabsorbers of the friction-disc type by which the return of the suspension springs of vehicles to normal position is braked by means of a resilient device which is initially in compression and lengthens without opposing effort when the shockabsorber moves from its normal position, but resists return to that position, the resilient device is interposed between two points on each of the arms of the shock-absorber. Forked arms 1, 1<1>, Fig. 1, are pivoted together at one end by a bolt 2, friction washers 3 being interposed as shown in Fig. 2. The other ends of the arms are secured to the vehicle chassis and axle respectively. A piston 10 is attached at 13 to depending forked lugs 14 and is adapted to slide in a cylinder 7 carried by trunnions 8 on the arm 1<1>. A compression spring 11 is interposed between the piston and cylinder. In the position of equilibrium, the points 2, 8, 13 are in one and the same straight line, and on movement of the arms 1, 1<1>, the piston 10 slides out of the cylinder 7 the compressed spring 11 assisting this action and opposing the friction of the friction washers 3. The return is braked in a resiliently progressive manner by the spring 11. Instead of a spring 11, the cylinder may contain air or liquid and the piston may be provided with valves or apertures. The arms 1, 1<1> are connected to the chassis and axle by means of a cup 16, Fig. 3, integral with the arms and containing a cylindrical block 17 slotted or cut to accommodate a pivoted fork 21 attached to the axle 2.
