Title: Apparatus for loading goods on a pallet
IPC: B65G57/03
Filed: 1974-12-10
Abstract: 1472664 Pallet loading OKURA YUSOKI KK 10 Dec 1974 [19 July 1974] 53404/74 Heading B8C A presser 66 presses downwardly on bags B supported on rollers 8 above a pallet P as the rollers are withdrawn and the bags drop on to the pallet. Bags are fed from a roller conveyer 71 by a belt 73 to the rollers 8 with a pivoted stop 24 raised. The stop 24 is lowered and a side guide moved inwardly to locate the bags. An air cylinder 61 lowers the presser and chains 7 withdraw the rollers. After the bags reach the pallet, pallet platform 53 is lowered, until the presser is beneath the level of the rollers 66, by a piston rod 55 lowering a pulley 56 of a chain 57 which supports the platform.

Abstract: 1,249,976. Knitting-machines. WILLIAM COTTON Ltd. 15 Nov., 1968 [25 Nov., 1967], No. 53727/67. Heading D1C. A straight bar machine has provision for changing from rib to non-rib knitting with loop doubling, including loop spreaders 7 fixed to the machine needles 2, spaced ones 7a of which are attached to the opposite sides than the remainder. When the change occurs previously inactive frame needles 1B engage spreaders 7 and receive the loops. Spreaders 7a transfer their loops to spaced needles 1A1 already bearing loops. The loops are then engaged by transfer points which are moved to close the gaps between adjacent groups. In one example spaced blocks of points are closed together while in another a successively smaller number of loop groups are successively moved one needle space towards the centre of the bed.

Title: Position locating system

Filed: 1971-11-24
Abstract: 1321730 Radio navigation GENERAL SYSTEMS DEVELOPMENT CORP 22 Nov 1971 [23 Nov 1970] 54181/71 Heading H4D In a vehicle (including craft) radio navigation system utilizing phase differences between received sequentially-transmitted radio (e.g. "Omega") signals each vehicle carries a reference frequency source and determines the phase difference between each received signal and the reference source; the phase data is transmitted (digitally) to a communication station which has an associated central processor, time shared with other communication stations, for calculating vehicle position from the phase data. Vehicle position data is transmitted back to the vehicle. To allow for several vehicles transmission time at the communication stations is time-shared. To communicate with a station a vehicle selects from a series of time blocks the strongest signal (and hence the nearest communication station) and seizes an idle time slot within that time block. Acknowledgment and synchronizing methods are described to ensure accurate synchronization between stations and vehicles and to prevent vehicles from receiving each other's data. Ambiguity in position measurement is resolved by a range measurement utilizing the round-trip delay for a message from the communication station to a vessel.

Abstract: 1,131,288. Hydraulic systems. BONSER ENG. Ltd. March 23, 1967 [Dec. 28, 1965], No.54896/65. Heading F1P. A piston 27 is movable in steps along a cylinder 26 by supplying liquid to a cylinder chamber 33 to move the piston 27 into abutment with a stop piston 31 prevented from moving by liquid trapped in a cylinder chamber 35. The space 34 between the pistons 27, 31 is connected to atmosphere through a passage 36 in a piston rod 28. To re-position the stop piston 31 in preparation for the next movement step of the piston 27 and rod 28, a changeover valve 11 is reversed whereby a spring 32 disposed between the pistons 27, 31 reacts against the piston 27 and the liquid trapped in the cylinder chamber 33 by the valve 11 to move the stop piston 31 to the position shown where it engages an abutment 29 adjustably fixed to the rod 28, the liquid in the cylinder chamber 35 displayed by the stop piston 31 being exhausted through the valve 11. In an alternative arrangement Fig. 1 (not shown), the piston and cylinder is of conventional construction and the exhaust from one side of the piston is delivered to another cylinder (6) and presses a spring loaded piston against an adjustable stop (24) the thus trapped liquid preventing further movement.

[Also in Division F2] A valve for controlling the flow through a domestic ventilation duct has sector shaped closure elements 43a, 43b mounted on a sleeve 40 and movable over the sector shaped openings 33a, 33b in an end wall 32. The sleeve 40 is attached to a wheel 44 carrying vanes 45 and mounted magnetically on the head 39 of a shaft 36 which is biased by a spring 38 to a predetermined valve open position. Increase of flow through the duct acts on the vanes 45 to cause the valve closures to move to regulate the flow.

The vanes are surrounded by an annular passage between the duct 31 and the ring 46 formed by the spaces between radial arms 47 which spaces are adjustable by the apertures in a ring 49. In modification the vanes are formed in a room diffuser which is adjustable in height and the vanes are adjustable or auxiliary adjustable vanes in the duct direct the air on to fixed rotatable vanes. In a further embodiment vanes are integral with the valve closure elements and helicoidal ramps separate the respective turbulance fileds.
