Title: A Method and Arrangement for Determining the Mechanical State of Machines
Inventor: SOHOEL EIVIND OLAV
IPC: G01H1/00
Filed: 1968-02-23
Abstract: 1,157,062. Testing machines electrically. KONSULTBYRAN IKO A.B. Feb. 23, 1968, No.8831/68. Heading G1N. The output of a vibration pick-up (not shown) is filtered at 200 to pass only those high frequency oscillations which correspond to mechanical transients set up in the pick-up by vibration of a machine under test, the electrical oscillations corresponding to the actual machine vibration not being utilized. The characteristics of the pickup being known, the high frequency output provides a measure of machine vibration and hence of wear. The pick-up output is applied to a filter unit 200, which feeds both a measuring unit 300, which determines the frequency of occurrence of transients above a certain amplitude, and also a second measuring unit 400 which determines the maximum energy content of the transients over a given period. The signal to unit 400 may be passed first through a segregating unit 500 which is synchronized to the machine under test and enables the energy content of transients occurring at a given point at each cycle of operation of the machine to be measured. The transients produced in the output of a Piezo electric pick-up attached to the machine are separated from background vibrations by a filter (204-209, Fig. 2a', not shown) in the unit (200, Figs., 2a<SP>1</SP> and 2a<SP>z</SP>, not shown). The unit (200) also includes differential amplifiers (212, 217, 221, 225, 228 and 250) pulse shapers (218, 251) and integrators (221, 233) for producing, for each transient, a pulse (5, Fig. 2b not shown) with an amplitude proportional to the energy content of the transient (1). The measuring unit (300, Fig. 3a, not shown) includes a monostable (305) and produces a pulse (8, Fig. 3b, not shown) for each energy pulse (5) in excess of a certain level (6), and also an integrater (307, 308) giving an output proportional to the occurrence frequency of the pulses (8). The second measuring unit (400, Fig. 4a not shown) includes an integrator (407, 408) whose output (9, Fig.4b not shown) represents the maximum amplitude of pulses (5) over a period of time controlled by a switch (410). Alternatively the period of time is controlled by the segregating unit (500, Fig. 5a not shown) which receives a synchronizing pulse (13, Fig. 5b not shown) from the machine and generates a sawtooth (14), the period being selected by adjusting (at 510) a voltage (15).

Title: Improvements in and relating to conveyor apparatus for feeding articles such as eggs
Inventor: BILLINGHAM RAYMOND CLARENCE
IPC: B65B23/06
Filed: 1952-04-10
Abstract: 720,499. Conveyers. CO-OPERATIVE WHOLESALE SOCIETY, Ltd. July 7, 1953 [April 10, 1952], No. 9169/52. Class 78 (1). [Also in Group III] In conveyer apparatus for feeding articles such as eggs to grading, sorting and packing machines, the articles are placed on a moving endless conveyer which passes below a series of guides or deflectors comprising a plurality of wires suspended above and lengthwise of the conveyer and appropriately spaced away from it to form a number of channels leading to the destination. As shown in Fig. 2, an endless conveyer 1 passes an egg-testing bench 9 at which testers sit on stools 12, receiving eggs from crates which pass from a table 14 to a roller-way conveyer 13. After testing, the eggs are placed on the conveyer 1 and the empty crates on the lower run of that conveyer where they are retained for refilling by a stop 15. On the conveyers the eggs pass deflectors 17 and 40 and travel between suspended members forming channelled guides directing them to the channels in cross conveyers 22a, 23a, leading to testing stations 22 and 23. As shown in Fig. 7, transverse members 28 support threaded rods 29 which have nuts 29a for vertical adjustment and also transverse adjustment, holes being provided in the member 28. Flat metal strips 30 are attached to the rods 29, and inverted T-shaped members 31 carrying wire guides 32 just above the conveyer surface are attached to the metal strips. The eggs contact the wire guides 32 during their travel and are guided on to the transverse conveyers 22a, 23a by a single wire having a forked end. The deflector 17, comprises a metal strip 18 secured to the conveyer table 7, a wire fender 19 normally of rubber covered wire, and an egg contacting guide wire 21 secured by studs to the strip 18. The deflectors 40 have arms 37 adjustably pivoted to a transverse member, the deflectors being adjustably pivoted to the arms. The deflectors comprise an upstanding fin secured to a wire base mounted on a screwed rod connected to the arm 37. Rounded members 16 are placed between the belt 1 and supporting plate 7 at the testing station and metal cross members under the plate 7 to strengthen the conveyer, those near the conveyer 22a, 23a being raised at the centre to cause a tendency for the eggs to roll to the outer edges and assist delivery. Stop members at the ends of conveyers 22a, 23a, hold back surplus eggs and for filling any spaces left. To improve the surface of the conveyer it runs under a felt strip in contact with the surface. The system may be duplicated. The entrance to the grader conveyer has flanged rollers mounted on a pivoted axis and the conveyer has suspended guide plates.

Title: Improvements in or relating to lubricating device
IPC: B61F17/22
Filed: 1956-03-26
Abstract: 790,889. Lubricating. KLINGLER, K. A. March 26, 1956, No. 9365/56. Class 12 (3). A lubricating device for use with a rail vehicle journal box having a reservoir for lubricant comprises a roller 14, Figs. 1 and 2, supported in contact with the journal 2 by arms 33 provided with rollers 35, 42 which are resiliently engaged with the journal 2. The roller 14 is secured to a shaft 13 which carries distributers 22, 23 of rubber or other suitable material. Each distributer is disc-shaped, of a diameter greater than that of the roller 14 so that it is bent where it engages the journal. A shield 50 of rubber or other flexible material is secured to the arms to confine the lubricant to an area of the journal. Stop members 57, 58 limit the axial displacement of the device along the journal 2. In the construction shown in Figs. 7, 8 and 10, a support member 66 with resilient packing 67, supports a shaft 68 on which is mounted a roller 70 which is in contact with the journal 61 and forms a backing for a lubricant distributer 72 of rubber or other equivalent material. The support 66 is cut away at 77 to receive a plate 78 which is fitted on to the shaft 68 and carries two rubber members 82, 83 adapted to engage the journal 61. The support 66 and lubricating distributer 72 are held in position by a pair of journal-embracing arms 84, 85 formed of resilient metal connected by setscrews to the support 66. Each arm at its upper end has a pair of rollers which bear against the journal 61. Each pair of rollers, e.g. e.g. rollers 105, forms part of an assembly which is pivoted to the arm and has an upper surface 106 inclined at a small angle to the axis of the rollers. As the journal 61 rotates the. frictional resistance of the roller members of the attachment will rotate the attachment until the inclined surface 106 on one or other of the roller assemblies engages the portion 63 or 64 of the brass 62. This causes the rollers, e.g. rollers 105, to tilt and produce axial movement of the attachment outwardly with respect to the journal. Such movement is limited by abutment of a part 93 of the arm 85 with a portion 63 of the brass. The roller-carrying members may be spring-biased to increase the force tending to move the attachment along the journal. In a further construction shown in Fig. 12, the journal-embracing arms 125, 126 are pivoted at 127 and are biased towards each other by the arms of a spring 128 wrapped around the pivot. The arms may be prevented from opening to disengage the lubricating device from the journal, by the provision of a downwardlyslidable arm 135 which has a locking-head 137 capable of being inserted between both surfaces 138 on the two opposed arms 125, 126.
