Title: Conveying apparatus for use in the treatment of veneers
IPC: B27G11/00
Filed: 1944-07-26
Abstract: <PICT:0585706/III/1> <PICT:0585706/III/2> <PICT:0585706/III/3> In conveying apparatus for use in the treatment of veneers, the veneers are held by one or more gripping elements secured to a movable member which is caused to travel in a predetermined path from a coating device to a drying device, the movable member and the gripping elements being displaced by a chain to which they are periodically attached and from which they are periodically released.  Veneers are transferred from coating rollers b, Fig. 1, to a drying device by being clipped to a rod x which is pushed along guides by a dog d1 on an endless chain d.  The rod x carries a fixed jaw c2, Fig. 2, and a movable jaw c1 and is inserted by hand through a slot f into guides g1 down which it is pushed past pivoted lugs h until it rests on pivoted lugs k.  The lugs h are mounted on a vertically movable and pivoted member b which is linked to a pivoted arm i.  When the dog moves this arm, the lugs are moved downwards and the stick is pushed past the lugs k into a guide j with the tail of the movable jaws bearing against a bar p.  When the dog engages the stick, the jaws are opened as shown in broken lines and are kept open as they pass around the lower sprocket e, Fig. 4, in order to receive the veneer which is fed into them by the rollers b.  As the stick moves upwards the jaws are closed slowly by engagement with a pivoted arm g.  This arm has a pin-and-slot connection with a longitudinally movable weighted rod r.  Means are provided for preventing movement of the stick past the lugs k unless it is horizontal.  For this purpose an arm m, Fig. 3, fast on the shaft carrying a lug is connected by a link m1, and a ball joint to an end of a bar n.  This bar is constrained by a block n1 and guide strips o only to move parallel to itself.

Title: Device to introduce an optic measuring index at photoelectric detection of photographic plates
IPC: G01D5/34
Filed: 1973-03-27
Abstract: 1429536 Examining photographic plates &c SAAB-SCANIA AB 27 March 1973 [27 March 1972] 14693/73 Heading G1A In a device for investigating photographic plates 2 and the like radiation M passing through the plate is split into three beams by Abbe-cubes 16, one beam going to a projector screen 20, the other two being directed to separate detector systems where the images of the detector plate formed at a slot aperture 4 in front of each detector system are scanned by means of vibrating prisms 22x, 22y in two perpendicular directions. An image of a reference grid or pattern, to enable determination of the co-ordinate position of the instantaneous portion of the image being scanned, is also superimposed in each of the image planes of the photographic plate at the slots 4, by means of a reference beam R passing through a measuring index disc 32 and a focusing lens 31 co-operating with the Abbe-cubes 16 as shown. The reference beam R and the measuring beam M are distinguishable from one another by inserting a filter 33 (blue) in the measuring path M and constructing the measuring index disc to pass only say, red light, the detectors (a photo-multiplier 21 x and a photo-diode 34x) being chosen or arranged to be sensitive to the corresponding wavelength. Thus the output of one detector (the photo-multiplier) indicates the transmitivity of the portion being scanned while the output of the other detector indicates its relative position. The photographic plate 2 is attached to a holder 6 which is movable in two co-ordinate directions by a system of rollers and rails 7 and 8 to enable different portions of the plate to be investigated. A rotating chopper 28 in the beam periodically interrupts the measuring beam and periodically allows radiation reflected from a mirror 27 to pass via light fibres 25, 26 and an aperture 24 in the chopper, into the measuring beam path and thereby causes "reference pulse" to be formed by the detector at the beginning of each scan. The description discloses several forms of the measuring index disc may take Figs.2, 3, 4 (not shown), that is, half transparent to red light, one quarter transparent or comprising one quarter transparent together with a series of diagonally arranged smaller transparent squares.

Title: Improvements in instruments for measuring inner diameters
IPC: G01B5/08
Filed: 1949-06-01
Abstract: 680,287. Gauging-apparatus. SOC. D'APPLICATIONS ET DE CONSTRUCTIONS POUR MATERIEL AUTOMOBILE, S.A.C.M.A. June 1, 1949 [June 8, 1948], No. 14721/49. Class 106 (ii). An instrument for measuring a diameter of an annular space has an arcuate body shaped to contact one wall of the space in at least three points on two distinct generatrices of said wall, means carried by the body to measure the distance to the wall and resilient push-pieces carried by the body to engage the other wall of the space. In a pneumatic gauge for measuring the diameter of the outer wall 25, Fig. 1, of an annular space, air or other suitable fluid is supplied under pressure to a nozzle 30 in an arcuate body 27 shaped for contact with the wall along two lines 28, 29 and held against the wall by balls 39 which bear on the inner wall. The balls 39 are carried in the ends of two bars 35, each of which is secured centrally by a screw 36 to the body 27, and the elasticity of the bars urges the balls against the wall 26. A flange 40 makes the body 27 rigid. The arrangement may be reversed to measure the diameter of the inner wall. Specification 367,700 is referred to. The Specification as open to inspection under Sect. 91 comprises also pneumatic gauges for measuring small or large internal diameters. In the first case, a crescent-shaped body 1, Fig. 1 (Cancelled), rests in the bore along two lines 5, 6 and the fluid under pressure is supplied to a nozzle 8 through a chamber 11. In the second case, a mechanical feeler 23, Fig. 3 (Cancelled), of a pneumatic gauge is supported in a rectangular plate 15 which bears on the test surface along lines 16, 17. Specification 612,010 is referred to. This subject-matter does not appear in the Specification as accepted.

Title: Circuit breaker
IPC: H01H73/42
Filed: 1974-04-03
Abstract: 1462692 Circuit-breaker mechanism MATSUSHITA ELECTRIC WORKS Ltd 3 April 1974 [6 April 1973 (3)] 14757/74 Heading H1N A circuit breaker operating mechanism comprises a pair of base-plates 33, 33<SP>1</SP> between which an actuating member 38 is pivoted about one limb 37a of a U-shaped shaft 37. The actuating member 38 is formed as a pair of spacedapart, parallel strips; the longer limb 37a of the U-shaped shaft extending through the holes 38a and through corresponding holes 75 in the base-plates to provide the pivot, whilst the shorter limb 37b extends through the holes 38b to provide a first fulcrum and a piece 38c provides a second fulcrum. A turning arm 40 is loosely held between these two fulcra near a cam lobe 40b by which it is retained in the ON position of the mechanism against the pull of a spring 56, its inner end being slidingly engaged in a pair of arcuate slots 39 by means of a pin shaft 41. Thus arcuate movement of actuating member 38 about its pivot 37a results in movement of the turning arm 40 provided the shaft 41 is restrained, and this is achieved by latching it in a slot 44b in a latch 42 which is also pivoted between the base-plates and is in turn latched by a pivoted trip member49, (see Fig. 13B). The trip member 49 has a projection 49b which is aligned with an overload trip device (25, Fig. 9, not shown) to release the latch against the action of a spring 51 and thus free the turning arm pivot 41 so that arcuate movement of the turning arm 40 can take place even if the actuating plate 38 were held in the "closed" position. Movement of the actuating plate 38 is effected by a handle 57 into which the ends of the U-shaped shaft 37 are received (Figs. 6, 9 and 22, not shown). Movement of the turning arm to the right effects corresponding movement of a link 22 against the action of spring 23, the link containing apertures through which contact arms 12 extend, and thus results in closure of the moving contacts 13 on to the fixed contacts 9 against the action of springs 14. When the latch is tripped to free the arm 40, the spring 23 returns the link 22 and allows the contacts to be opened by springs 14. An apertured plate is fitted beneath the operating handle on to the U-shaped shaft 37 to indicate the "tripped" condition of the circuit breaker.

A machine for weight-sorting objects comprising a plurality of weighing devices 16 mounted on a movable frame 5, 6, 7 and each provided with an element 19 positionable in accordance with the weight of an object supported by such weighing device, is provided with a plurality of stop members 15 movable into the path of the elements 19 so that during movement of the weighing devices 16 due to movement of the frame 5, 6, 7 the stop members 15 which are positioned in the path in accordance with various weight classifications each make contact with only those elements 19 whose associated weighing devices 16 support objects falling within a common weight category. As shown, the weighing devices 16 which each comprise a pivoted beam 17 integral with an element 19 and supporting an object container 21 and a pendulum weight 20 are spaced circumferentially on the periphery of the frame 5, 6, 7 which is centrally mounted by bearings on a stationary shaft 2 and which is arranged to be rotatably driven through a gear-wheel arrangement 4. Spokes 9, 10 which are fixed to and extend radially of the shaft 2 support vertically extending shafts 11. Arcuate guide members 14 on which the stop members 15 are located are attached at their ends to elements 12, 13 rotatable about the axes of the shafts 11. Depending on the number of guide members 14 associated with each shaft 11, the elements 12, 13 may each be V-shaped (in the case of two guide members 14 per shaft 11) or cross shaped (in the case of four guide members 14 per shaft 11) and rods 22, Fig. 2 may be arranged to inter-connect adjacent elements 12, 13. By manual adjustment of the rods 22 a specific one of the guide members 14 associated with each of the shafts 11 may be simultaneously moved to lie radially outwardly of the other guide members 14 from the shaft 2 so that the stop members 15 of these radially outward guide members 14 are in the path of rotation of the elements 19 about the shaft 2. When the element 19 of a weighing device 16 supporting an object contacts one of the stop members 15, the container 21 is opened to discharge the object to a station corresponding to its weight category. Instead of inter-connecting rods 22 the elements 12, 13 may be inter-connected by a gear-wheel arrangement, Fig.4 (not shown) and instead of moving in a circular path the weighing devices may be arranged to move recti-linearly.
