Title: Improvements in or relating to signal receiving systems
IPC: H04B1/10
Filed: 1928-05-18
Abstract: 290,979. Koerts, A. May 21, 1927. [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Atmospherics, eliminating. - A wireless receiving-system is arranged to isolate the active parts of interfering disturbance and separately neutralize them bv the use of one or more devices having non-linear characteristics. The active parts of the disturbances are where a sudden change of intensity occurs and are isolated by an oscillating circuit so damped that the oscillation produced by the active part of the disturbance dies down before the arrival of the next active part. The disturbances thus isolated are used to neutralize the disturbance produced in a circuit tuned to the signals after a frequency-changing process. Alternatively a band in the received frequencies in the neighbourhood of the signal frequency is removed by filtering and then replaced by a frequency changing process, thus producing disturbances free from signals which is used to neutralize the disturbance in a circuit tuned to the signals. A number of spaced aerials may be employed.

Abstract: 854,195. Endless conveyers. GRAHAM-ENOCK MANUFACTURING CO. Ltd. May 9, 1958, No. 15023/58. Class 78 (1). [Also in Group XVII] A bottle crating and/or decrating machine which may be as described in Specification 747,138 is supplied with crates by an endless conveyer having means to assemble two or more of them in the loading or unloading position by arresting each crate longitudinally and then clamping the group arrested transversely. A crate leaving the machine operates a trip 8 causing a stop 6 to halt the following crate A on the conveyer 4. The crate A operates trips 13, 14 which render active trips 11 and 12 and cause a spacer stop 15 to rise behind it. The following crate B in operating the trip 11 causes a stop 9 to rise beneath it and to obstruct the passage of the next crate C. The crate B then operates the trip 12 whereby members 17 clamp the two crates. Operation of one pair of clamps results in a member 26 acting on a valve 22 to initiate operation of the machine. If no crate is present the clamps close without the valve being operated. A signal from the machine at the end of loading or unloading removes the stops 6, 9, 15 and retracts the clamps to permit crate movement again. The apparatus may be pneumatically (as shown), hydraulically or electrically operated. Specification 647,446 also is referred to.

Convention date, May 18, 1933. [Class 100 (i)] Apparatus for guiding the cloth in cloth shearing, teasing, calendering, or other clothtreating machines comprises a device such as a cylinder or the like adapted to feed or guide the cloth through the machine, which is arranged to be displaced automatically in a direction parallel to the axis thereof so that the cloth is displaced transversely to the direction of feeding, and a table which guides the cloth upon entry into the machine, arranged to be displaced simultaneously with the displacement of the cylinder in such manner that the cloth moving from the table is accommodated to the displaced position of the cylinder. The apparatus is described as applied to a cloth-shearing machine. A hollow cylinder 7 provided with a roughened surface is rotatably mounted by means of ball bearings on a non-rotatable shaft 5 which is slidable at one end in a bearing bracket 6. The other end of the shaft 5 is screw-threaded and engages in a screwed bearing which is held in a bearing bracket 4 and rotatably mounted on a ball bearing therein. Two pulleys 1, 2 are secured to the screwed bearing, which on rotation move the shaft 5 and cylinder 7 longitudinally. A brake band co-operates with a collar on the ball bearing extension of the cylinder 7 at the end adjacent the bearing 6. The feeding hopper or table 15 on which the cloth is placed in folds is mounted on a shaft 11 for limited movement at right angles thereto, and for longitudinal movement thereon. The shaft 11 is rotatable in a fixed bearing 12, and passes through a pivotal support 13 mounted on the side of the table 15. The support 13 carries an internally-threaded sleeve which engages a threaded portion on the shaft 11, so that the table 15 moves along the shaft on rotation of the latter. The table 15 is provided at one corner with a leg 17 pivotally mounted on the floor by means of a ball joint; while the other three corners are provided with swivelling-wheels 171. The thrust imparted to the table on the rotation of the shaft 11 causes the table to perform small rotational movements about the leg 17. A feeler device adapted to test the position of the cloth operates a mechanism to drive the pulley 1 in the desired direction to move the cylinder 7 transversely to register the cloth to the correct position, and the pulley 2 drives simultaneously the shaft 11 through a pulley 10 secured thereon to move the table 15 and the cloth thereon in the same direction as the cylinder 7.
