Title: Colour comparator apparatus
IPC: G01N21/29
Filed: 1950-06-05
Abstract: 699,181. Colour comparators. ADLER, R. June 5, 1950 [June 4, 1949], No. 13936/50. Class 97 (i). A colour comparator comprises an opaque casing having its front wall provided with a viewing opening and its rear wall provided with a light-entrance opening aligned with the viewing opening, the top wall of the casing being provided with at least one opening through which the lower portion of a tube may be inserted in the casing into alignment with and between said openings in the front and rear walls, a disc rotatable in the casing between the front and rear walls and disposed so that its periphery overlaps part of the openings in these walls, and a series of colour standards carried by the disc so as to contact a portion of a tube inserted in said top wall opening. The casing 6 of the comparator shown has two communicating and offset openings through which tubes 21, 22 containing liquid may be inserted into the casing to lie in the light path between the rear wall opening and the observation opening 15 in the removable front wall 11, which carries rotatably a disc 18 having in peripheral slots colour standards 33 of flexible material adapted to contact tube 21. To compare a coloured liquid with the standards only tube 21 is used, the light passing horizontally through this tube and through the colour standard contacting it. Alternatively, a. reflector may be slid through a slit 28 in an end wall to lie beneath a container which is longer than container 21, the light from this container being directed horizontally for comparison with light passing through the rear wall opening and the colour standard only. When a liquid has a natural colour or turbidity and it is desired to compare the colour produced in the liquid by the addition of reagents with a colour standard, two tubes 21, 22 are used, tube 21 containing the treated liquid and tube 22 the untreated liquid. In this case light from the rear wall opening passes through the treated liquid and is compared with light passing through the untreated liquid and the colour standard. Alternatively, a reflector may be disposed beneath both tubes so that the light passing vertically through the tubes is compared. To increase the amount of light passing down the tubes in such a case, the upper end of each tube may be provided with a pivoted plane mirror, a transparent sphere or a transparent bent tube.

Title: Improvements in or relating to lathes and like machines
IPC: B23Q35/10
Filed: 1922-05-18
Abstract: 202,406. Huguet, A. C. May 18, 1922. Lathes.-The slide-rest of a copying- lathe is provided with a plate having two parallel sliding members carrying the tool and tracer respectively and connected by a lever which is adjustably pivoted to vary the scale of reproduction. The slide-rest 2, Fig. 1, provided with the usual cross slide is fitted with a plate 3 having dovetail guides for parallel sliding members 7, 8 connected by a link 6 adjustably pivoted on a pin 5. The member 7 carries the spring-pressed tracer 15 contacting directly with a pattern 19 adjustably mounted on a support 20 carried by a cross-member 22. while the member 8 carries a tool 16 engaging the workpiece 17 mounted on the face-plate of the lathe. The profile of the pattern is thus conjugate to that of the work required, but in a modification the tracer 15 may be carried by a curved arm 96, Fig. 17, to permit of a positive pattern being used. The positions of the tool and tracer in the plate 3 may be interchanged. The tool is fed towards the work by means of a screw operated from a handle 26. In a modification, Fig. 2, the device may be arranged for operating on work mounted between centres, the member 22 being replaced by a member 31 disposed longitudinally of the bed and carrying a support 30 for a tailstock 29 supporting the rear end of the workpiece. The pattern 19 is adjustably mounted on a member 20. In a further modification, Fig. 15, the work 89 and pattern 87 are both mounted on a shaft 85 rotated between the centres. In order to reproduce the profile of a short pattern on a long work-piece the model may be traversed during the longitudinal movement of the slide by means of a forked member secured to the plate 3. In another modification, Fig. 12. the longitudinal dimensions of the work with respect to the pattern may be varied as required. The plate 3 is provided with an extension 63 having a guideway for a slide 66 supporting a transverse member 67 carrying the tool-holder 70, the movement of the latter being controlled in a direction transverse to the work by a tracer slide 7 through an extended lever 68 adjustably pivoted at 5. The slide 66 is connected through a lever 75 adjustably pivoted at 72 to a link 77 secured to the slide-rest 2 so that as the latter is traversed the tool-holder is moved longitudinally over the work, the ratios between the longitudinal movements of the tracer and pattern being variable by means of the lever 75. If desired, the tool 16 may be replaced by a rotary cutter. Tool-holders.-A number of work-pieces in series may be turned simultaneously by mounting several tools as shown in Fig. 18, the tools being clamped by bolts 99 between plates 97<1> secured to the member 8 by a third plate 12 and bolts H.

Abstract: 1,105,443. Change-speed gearing. MASSEY-FERGUSON Inc. 6 April, 1965 [9 April, 1964], No. 14459/65. Headings F2C and F2D. A vehicle transmission comprises a three-speed and reverse unit with axially engageable pinions, in combination with a two-speed clutchoperated unit doubling the number of ratios, the output shaft being coupled to an epicyclic overdrive unit providing a further ratio doubling. As shown, an input shaft 1 may be coupled to a drive shaft 13 by a main clutch 11, and a hollow countershaft 21 houses a power take-off shaft 9 driven from shaft 1 through a second clutch 3 and pinions 5, 7, the driven and output shafts 35. 63 being in line with shaft 13. Gear details.-The main gear consists of a pinion 33 engageable with countershaft pinions 31, 51 for first gear and reverse, and a double pinion 45, 43 engageable with pinions 39, 41 for second and third gears. The two-speed unit comprises high and low ratio pinion pairs 17, 19 and 23, 25, of which pinion 23 is secured to drive shaft 13 and pinion 17 may be coupled to the shaft by a friction clutch 15, pinion 19 being secured to countershaft 2] and connected to pinion 25 through a one-way clutch 27, 29, the portion 29 being splined to shaft 21. The clutch is constantly loaded by a spring 141. The epicyclic unit is of the three-element type with an axial coupling sleeve 62 for engaging teeth 65, 67 for direct drive between shafts 35, 63, or teeth 61, 68 for a reduced drive through planet carrier 57. Clutch details.-Friction clutch 15 comprises an annular actuator piston 101 in a cylinder 103 connected to a supply pump 109 controlled by a selector valve 107. Cylinder 103 is provided with a relief port 126 allowing the pressure liquid to escape under centrifugal force and thus at a rate dependent upon the rotational speed'. In the case of the one-way clutch 27, 29 the latter portion forms an annular piston in the hub cylinder 117 of pinion 19 loaded by the spring 141 :The hub 117 is also connected to the selector valve 107 through a restriction 143. Operation.-With valve 107 set to supply pressure liquid to friction clutch 15 drive is transmitted to shaft 21 through pinions 17, 19, the one-way clutch elements 27, 29 overrunning. To engage the lower gear valve 107 is reversed to disconnect clutch 15 from, and connect clutch 27, 29 with, the pump 109. Pressure in clutch cylinder 103 then falls as liquid escapes through port 126 to reduce the speed of pinions 17, 19 until clutch elements 27, 29 are rotating at the same speed, when spring 141 acts to force them into engagement. Pressure in clutch 27, 29 then builds up through restriction 143 to prevent overrunning. To reengage the higher gear, valve 107 is operated to reverse the clutch pressure connections, engagement of clutch 15 increasing the speeds of pinions 17, 19 to separate elements 27, 29 against the action of spring 141. to allow over-running, the liquid escaping freely through a by-pass valve 145.

Automatic speed and power control; brakes, arrangement and disposition of, and braking.- A tractor for aerial ropeways &c. has an engine carried by a centrally-pivoted hanger and is provided with speed-regulating control apparatus automatically actuated by the normal or by the catenary gradient of the track and by strikers carried by the arms of the track supports or adjacent to the track. The tractor frame a<1>, Fig. 1, carries a pair of track wheels a<2> and has central pivots a<4> from which is suspended a hanger a' carrying an internal combustion or other engine a<6>. The engine driving-shaft b carries a centrifugal brake and a sprocket wheel geared by a chain b<3> to an annular sprocket wheel b<4>, Fig. 4. running on ball bearings b<9> and connected through a multiple-disk clutch b<8> to the ball bearing supporting a disk b<10> fixed to a hollow shaft b<11> carrying spur-pinions b<12> gearing with spurwheels b<13> on the track wheels. The clutch is automatically disconnected by a push-rod c, sliding within the hollow shaft, and having a projecting end c<3> operated by an undulating annular cam c' on a star-wheel c<4>, when an arm of the star-wheel strikes a stop c<8> on one of the track supports or adjacent to the track. A peripheral cam d<2> on the star-wheel simultaneously controls the throttle valve by raising a roller d, Fig. 5, on a slotted lever mounted on a pivot d<5> on the tractor frame and connected by linkage d', a rocking shaft d<10>, and linkage d<8>, to the throttle lever d<12>. The throttle valve is also automatically regulated according to the gradient of the track through the corresponding inclination of the tractor frame, the relative movements of the ends of the slotted lever and consequent operation of the throttle linkage. The track slipper brake e<3>, Fig. 4, is pivoted on a stud e and has guiding ramps engaging with ramps on the track supporting arms, which deflect it sideways clear of the arms. The slipper brake is carried by a pivoted arm e' whose free end engages a pivoted arm e<7>, Fig. 3, connected to a slotted lever e<10> engaging a stud on an arm e<12> projecting from the hanger. As the hanger tends to keep vertical, relative movement of the tractor frame causes the brake to be applied on a down grade. Dash-pots f are provided to restrain the oscillations of the hanger. The tractor may be provided with hauling sheaves engaging an auxiliary haulage rope, or the frame a<1>, Fig. 8, may be fitted with an endless track h<3> carried on wheels h<1> and driven by a central sprocket-wheel h<5>.

Title: Irradiation plant
IPC: G21K5/02
Filed: 1965-04-07
Abstract: 1,072,319. Endless conveyers. SULZER BROTHERS Ltd. April 7, 1965 [April 13, 1964], No. 14779/65. Heading B8A. [Also in Division H5] In an irradiation plant in which the closed loop conveyer has at least two parallel runs on each side of the radiation source positioned one behind the other with respect to the source, to improve irradiation efficiency, the movement of the conveyer is controlled such that the conveyer is advanced quickly while loads in a rear run are at least partially shielded from the source by loads in a run nearer the source, and is slowed down or stopped each time loads in a rear run are at least partially exposed through the gaps between loads in a nearer run. The conveying means may be a vertical chain conveyer having two parallel chains 4 interconnected by cross rods 6, from which loads 7 are suspended. A motor M drives the conveyer through sprockets 10, it to carry loads around a source 1 made of up radioactive cobalt elements 2. Preferably the movement of the conveyer is interrupted each time a load in a rear run is in a zone (exposure zone) opposite a gap between loads of the nearer run, by actuation of a switch 12 by the corresponding cross rod 6 or by a member attached to the rod. A timer controls the length of exposure before the conveyer is restarted. The position of the switch may be adjusted vertically so that the stopping position in the exposure zone may be accurately selected. More than one stopping position may be provided in each exposure zone, these positions being arranged symmetrically in the zone to obtain an overall optimum irradiation. In an arrangement in which two such positions are provided (Figs. 3, 4, not shown) a pair of vertically displaced contacts are necessary, with their associated timer controls.
