Title: A machine for digging into and removing earth or other materials
IPC: E02F3/348
Filed: 1923-10-11
Abstract: 222,681. Leroux, P. E. Oct. 11, 1923. Scoop-arm machines.-In a machine for digging and shovelling, of the type comprising a frame supporting a conveyer co-operating with a digging member or pick axe and shovel mechanism adapted to deliver to the conveyer, the digging and shovelling operations are effected by separate tools, the material being first disintegrated by the pick axe and then lifted by a shovel which is operated by the pick axe at the end of its forward stroke. The pick axe 1 and shovel 2 are operated by a lever 6 connected through a rod 11, crank 12, eccentric gears 14, 15 and worm gearing with a shaft 19. which is driven from the engine 34 through crank 33, gears 32, 31, 29, 28, 26, 25, 21, 20 and a clutch 23 operated by a handwheel 24. The supporting wheels 65 have tyres with flanges for running on rails and teeth for running over ground operated on and are driven from the shaft 30 carrying the gears 29, 31. The said shaft 30 carries bevel pinions 35, 36 which can respectively be locked to the shaft 30 by clutches 37, 38 and which gear with a pinion 39 on a shaft 40 carrying a worm 41 gearing into a wheel 42 on an axle 43. The axles 43, 48 are coupled by a chain 49 passing over pinions 50. The clutches 37, 38 are operated by a fork 44 on a shaft 45, operated by a crank and rod 46 and hand-lever 47 which thus controls the forward or backward movement of the machine. In the shaft 27 carrying the bevel pinion 26 oscillates a frame 51 resting on rollers 52 and in this frame is the shaft 22 carrying the gears 21, 25. On the said shaft 22 oscillates the supports 53 of the frame of the conveyer 54 of which the table is supported on shafts 3, 55 and adjustable shaft 56. The shaft 55 is driven by a chain 57 passing over a pinion 58. The conveyer is supported by a roller 59 and bearing track 60 and is adjusted in position by a handwheel 61, operating a chain 62, and by a handwheel 67 and nut 68 which latter is so arranged as to allow the conveyer 54 and tools 1, 2 to rise over obstructions. In operation, the crank 12 revolves and advances the pickaxe 1 into the ground until a projection 7 therein engages the shovel 2. The pickaxe and shovel rotate so that the latter is first filled and then reverses itself, throwing the material into the conveyer. By means of the eccentric gears 14, 15 the pickaxe works at a minimum speed when cutting and the speed is greatest when the shovel raises the material.

In Figs. 1 and 2 the encoder housing 4 is bolted to the motor by three bolts 12, and contains an apertured or patterned disc 15 attached to the shaft by collet 14 and spring 16. The disc rotates between two printed circuit boards 18, 19 carrying optical sources and detectors, Fig. 1 is an exploded view; Fig. 2 shows the operational position. These boards are supported by a housing 9 having a portion 50, Fig. 2, which fits around the shaft so as to allow arcuate movement of the housing relative to the shaft. This portion 50 slides between two plates 5, 7, Fig. 1, to keep the boards spaced from the disc. The arcuate movement is effected by turning screw 73, Fig. 2, which is differentially arranged with a screw 74 to move the housing 9 against the bias of spring 54a on screw 54. After initial setting up, the housing 9 is locked in position by tightening screws 40. The encoder can be used to measure shaft rotation speed, and the measured value can be compared with a pre-set value to control energizing pulses and hence the motor speed, Fig. 6 (not shown).

Title: Winding flexible tubes to form a coil
IPC: F28D21/00
Filed: 1976-06-21
Abstract: 1528063 Coil forming method and apparatus; tensioning ATOMENERGI AB 21 June 1976 [1 July 1975] 25579/76 Headings DID and D1T A method of winding a plurality of flexible tubes 4, Fig. 9, into a coil form such that at least some of the turns of the coil are separated in the axial direction of the coil by means of substantially radially disposed separator elements 2a, 2b, and such that at least some of the turns of the coil are separated in the radial sense by the introduction of separating means 5, is characterised in that the separating means 5 are held against circumferential motion relatively to the turn or turns on which they rest, both in and in opposition to the direction of winding of the coil, by the substantially radially disposed separator elements 2a, 1b; and in that the separating means 5 are locked in the radial direction of the coil by winding the tubes 4 over then. As shown in Fig. 3 the separating means in the form of bars 5 can be held in a supply magazine 20 and be removed therefrom by arms 15 secured to and rotating with end plates 25, the arms 15 serving to guide a removed bar 5 into the space between adjacent separator elements 2a, 2b. To facilitate this the arms 2b may be longer than the arms 2a. The end plates 25 can constitute the permanent end plates of a heat exchanger and for this purpose one end plate can have a central aperture through which air to be heated or cooled can be fed to the centre of the coil. As shown in Fig. 7 the drum 1 that carries the tube separator elements 2a, 2b may be formed with a recess 3 in which a manifold tube (not shown) may be housed, the plurality of tubes 4 being connected to the manifold. Fig. 7 also shows how the separator elements 2a, 2b can be mounted on end plates 17 so that the elements 2a, 2b and end plates 17 can be slid axially off the drum 1 when the coil has been fully wound. Fig. 9 shows a tensioning device. A brake 6 comprises a stationary brake pad 6b and a moving brake pad 6a. The brake pad 6a presses the tube 4 against the pad 6b. As the wound coil increases in diameter it rocks a two-armed lever arrangement 32, 34 about a pivot such that one arm 34 exerts a lifting action on the pad 6a and so reduces the braking force of the brake 6. The arm 34 is in the form of a spring and is designed to produce a very gentle reduction in the braking force.

Abstract: 1518682 AFC systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd AND NIPPON VICTOR KK 20 June 1975 [25 June 1974] 26296/75 Heading H3A In a phase lock loop including a phase comparator 13, a controlled oscillator 17 and an adder 16 for angle modulating the oscillator 17 by a modulation signal at 10, loss of loop lock due to a high level modulation signal or frequency fluctuation of the oscillator output due to drift or temperature is prevented by deriving through an arrangement 19 responsive to each exceedance of a normal operating limit of the phase comparator 13 to provide a stepped waveform which is added at 14 to the phase comparator output to provide a control signal for the oscillator 17. The addition of a correction signal at 14 increases the effective operational range of the phase comparator and the lock-in range. The circuit 19 for producing a stepped waveform from the beat frequency error output of the comparator 13 includes a differentiator 21 followed by detectors 22, 24, wave shapers 23, 26 for causing a counter 27 to count up or down. A D/A converter 28 converts the counter ouput into a stepped waveform which is combined with the original beat signal at adder 14 (see waveforms in Fig. 2) to produce a sinusoidal output. It is mentioned that the counter 27 may be replaced by a shift register and the D/A converter 28 by an integrator. In the alternative embodiment of Fig. 3B, the sense of change in the comparator 13 output are first detected and then differentiated for driving the counter.
