Title: Wheel set measuring apparatus
IPC: G01B5/14
Filed: 1976-04-30
Abstract: 1501032 Measuring railway wheel sets: Tracking vehicle wheels WILHELM HEGENSCHEIDT GmbH 30 April 1976 [5 June 1975] 17826/76 Headings G1M and G1X Measuring apparatus for determining dimensional parameters of a wheel set comprises a support 12, Fig. 5, sensing elements 15, 16 axially displaceable into contact with slowly rotating wheels 17, 18 of the set, means for registering values indicative of the respective displacements of the sensing elements with respect to a datum plane 4, means for summing the values and registering the result and means for subtracting the values and registering the result of the subtraction. The wheel set is tested to determine the axial positions Ar 1  and Ar 2  of each wheel from the datum plane 4 and also to determine any wheel wobble. In Fig. 1 the ideal wheel set has vertical wheels in planes 6, 7 spaced equally from the plane 4 and it is required to determine the dimensions of a test set comprising wheels 2, 3 and to find the maximum and minimum distances of Ar 1  and Ar 2 , such as Ar 1  max and Ar 2  max, and the total wheel wobble 2G which is 0À5mm in each case in the figure. The set is mounted above the support 12 and rotated slowly to provide a series of such measurements which are recorded to provide also the lower values of Ar 1  and Ar 2  which are 681 mm. and 680 mm. respectively in the test example shown. In operation, the pins 15, 16, Fig. 5 are retracted by means of cylinders 24, and the support 12 is then positioned by a cylinder 38 to lie exactly beneath the datum plane 4. Dial gauges 8-11 are then zeroed or referenced to read for measurements of an ideal set and the pins 15, 16 then allowed to move outwardly to contact the wheels 17, 18 of the test set. The new readings of the gauges 8, 9 give # Ar and Ar respectively, # Ar being the difference between Ar 1  and Ar 2  and being obtained from movement of a lever 22 pivoted centrally at 21 to the support 12 and jointed also to the pin 16. By the use of lag indicators the minimum and maximum values for these parameters can be established and compared with permissible tolerances. The gauges 8, 9 may if necessary be replaced by digital transmitters connected to a control unit. The gauges 10, 11 indicate the variations in the distances Ar 2 , Ar 1  or the wobble or out of truth of the respective wheels. In Fig. 6 (not shown) the dial gauges are replaced by electronic measuring elements (31), (32) which give output signals which are fed to indicators which not only give the maximum values of Ar 1  and Ar 2  but sum and subtract them as before in the mechanical arrangement of Fig. 5. A further indicator gives wobble for both wheels and records the readings. In other figures (not shown) different rotational positions of the wheels are considered.

Title: Improvements in disconnectible discharge nozzles for lubricators
IPC: F16N21/04
Filed: 1933-06-27
Abstract: 417,147. Lubricator couplings. BRETTELL, F. G., 14, High Holborn, London. -(Lubrication Corporation ; 910, South Michigan Avenue, Chicago, U.S.A.) June 27, 1933, No. 18288. [Class 99 (i).] A lubricator coupling nozzle comprises a twopart conduit member C, Fig. 1, having a discharge orifice D at one end against which the nipple on the part to be lubricated may be clamped by a sleeve member A which is slidable on the conduit C and is provided with a clamp portion B. The conduit C and sleeve A are normally held in the position shown by a compression spring 17 which is located within a chamber formed by an internal enlargement 9 of the sleeve between a bushing 11 secured to the sleeve and a shoulder 15 on the conduit and is sufficiently weak to permit relative movement of the sleeve and conduit upon application of the nozzle to the nipple. After engagement of the nozzle and nipple and during operation of the lubricator the clamping effect of the spring is augmented by the pressure of the passing lubricant which is transmitted to the chamber 9 through a passage 24 provided in the wall of the conduit. Relative rotation between the conduit and sleeve is prevented by a stud 7 on the sleeve which extends into a groove 8 on the conduit. The clamp portion B is formed by providing an opening 19 laterally through the conduit of diameter sufficient to receive the head of the nipple and also a slot 21 extending from the opening 19 forwardly and across the end of the conduit of width sufficient to permit passage of the neck of the nipple. In a modification, Fig. 3, the nozzle is provided with a plate member 84 which surrounds the conduit 62, 63 and is tiltable manually into contact with both an enlargement 80 of the conduit and a bushing 73 on the sleeve 65 to effect relative movement of the conduit and sleeve against the force of the spring 77.

Filed: 1927-07-09
Abstract: 274,459. Senat, H. D. July 13, 1926, [Convention date]. Boxes formed from special blanks; handles; covers.-In a box of tubular form with end closing flaps, two of the flaps 11, 13 on opposite sides of one end of the box are provided with elongated finger openings 29, 30 formed by partly stamping out tongues 22, 25 therefrom. When the box is closed the flaps lie upon one another with the tongues lying flat and closing the openings 29, 30 and the uppermost flap 13 is held secure by a strip pasted over its free edge and the side 2 of the box; when the box is to be carried the securing strip is torn away and the flaps 11, 13 are raised so that their free edges abut and the tongues 22, 25 are pushed in on their hinge lines 24, 26 respectively to abut and with the tops 31 of the flaps 11, 13 form a braced triangular handle-grip as shown. The scoring line 15<1> separating the flap 13 from the side 4 is offset from the similar scoring lines 15 of the other closing flaps by an amount equal to the thickness of the cartboard so that the flap 13 will be flat on the flap 11 when closed down. The box is preferably made of corrugated cardboard in which case the corrugations give the handlegrip extra rigidity. In two modifications the flaps 11, 13 do not each entirely cover the end of the box and the portions containing the openings and tongues are provided with scored lines so that they may be bent up out of the plane of the other portions of the flaps when forming the handle, and in one of these modifications the handle is arranged so as to extend only partly across the length of the flaps; the flaps are secured together by a pasted strip and by other strips placed over the corners where the edges of the flaps meet the sides of the box.

Title: Improvements in or relating to successively remotely reading data
IPC: H04Q9/00
Filed: 1969-04-10
Abstract: 1,262,541. Selective signalling. COMPAGNIE DES COMPTEURS. 10 April, 1969 [19 April, 1968], No. 18553/69. Heading G4H. In a system for transmitting the readings of a plurality of registers, constituted for example by counters, at remote stations A, B, . . . N, Fig. 5, to a central recorder 40, each remote station includes mechanism which when activated reads the data thereat, together with the address of the remote station, serially to a common transmission line 27, and which, at the end of the reading sequence transfers power to the next remote station to cause its data to be read, and so on. When a switch 29 at the central recording station is transferred to its position 30 as shown, power is supplied to a motor 7a at remote station A. This causes data to be read from station A by, inter alia, sensing coded scales on the cylindrical surfaces of the counter drums, the data being superimposed on the common transmission line 27 which also carries the return motor current. When the data transmission is complete switches 32 and 37 at station A are both transferred from their positions shown to their lower positions, in which positions power passes via switch 32 to station B, and switch 37 is ready, when at the end of a complete cycle switch 29 returns to its normal upper position, to apply power to the motor 7a at station A to cause it to reset station A in preparation for a further cycle. Resetting, like data transmission, is effected sequentially, station-by-station. In a modification (Fig. 5a, not shown) employing a more complex switching system, no more than two switch contacts are connected in series for any station. Several embodiments are described for transmitting the data registered at each remote station. In the first, Figs. 1, 2, coded cylindrical tracks 3 adjacent the numbers on counter drums 1 are sensed by brushes 4, and their reading is serialized by means of a transparent endless band 5 containing apertures so positioned that when the band 5 is driven by a motor 7 the brushes 4 are rendered operative sequentially. The band 5 also carries a pattern of apertures representing the address of the station at which the device is located. The sprocket holes 10 on the band 5 are also sensed to provide clock pulses (Fig. 6, not shown) which are superimposed upon the motor current (Fig. 6, not shown) and the data pulses (Fig. 6b, not shown) to produce a fourlevel transmission current (Fig. 6c, not shown). In a second embodiment, Fig. 7, the sensing brushes are arranged on a helix which is rotated in order to read the coded scales serially. In a third embodiment (Fig. 10, not shown) a single sensing brush carried by a nut on a threaded shaft is moved across the coded scales sequentially.

Title: Improvements relating to mosaic target electrodes as are utilised in television pick-up tubes
Inventor: JENNINGS ALBERT EDWARD
IPC: H01J29/43
Filed: 1951-08-08
Abstract: 709,945. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 8, 1952 [Aug. 8, 1951], No. 18647/51. Class 39(1) A mosaic target electrode, such as is utilized in television pick-up tubes, comprises a series of discrete conducting elements deposited on an insulating surface by evaporation of a metal through the interstices of a stencil, the area between the elements being provided with a further series of discrete conducting elements. In one method of making the mosaic a sheet of glass or mica provided with a conducting layer on one surface is mounted in a television tube, the tube is evacuated, and a layer of silver of a thickness of 20-40 per cent light absorption is deposited on the insulating surface by evaporation; the layer may then be baked at 300‹C in order to ensure aggregation but this is not necessary. The silver layer is oxidized by a high frequency discharge in oxygen, and bismuth or a bismuth-silver alloy is evaporated on to the silver layer through a stencil; the whole surface of the target is then sensitized with caesium. In an alternative method the bismuth or bismuth-silver alloy is deposited first through the stencil and a silver layer evaporated on top, the whole then being oxidized and photosensitized. When bismuth is used, the evaporation through the stencil may be performed first in a separate evacuated container. Pure silver may be used instead of bismuth or bismuth-silver alloy when the mosaic is required to be sensitive to infra-red radiation. This construction prevents the insulating parts between the conducting elements of a normal mosaic screen from being charged, and thus prevents what is known as "the photographic effect". Specification 498,134 is referred to.
