Abstract: 968,851. Haymaking machines. C VAN DER LELY N.V. Nov. 22, 1960 [Nov. 30, 1959], No. 40150/60. Heading A1F. In a rake-wheel type of haymaking machine capable of use as either a sidedelivery rake or a tedder, the main frame 1, in plan, is of multi-armed E-shape, with the rake-wheels mounted on the ends of the arms, one of which is extended to pass between the planes of rotation of two of the rake-wheels and to carry a groundwheel 5 at its free end. As shown in Fig. 1, the frame comprises three sections 2, 3, 4 bolted together by flanges 28, 29 and supported by castors 5, 6, 7, one of which, 7, is lockable as a direction-control wheel. A draw-bar 24 is pivoted to the frame to swivel about the castor-axis of the wheel 5, the draw-bar being also swivellable on a horizontal pivot 23. The rake-wheels are mounted on bent axles 19 which can be locked to bearings 17 on the ends of the arms 4, 14, 15, 16, in any of three positions; in two of these, shown full and dotted in Fig. 1, the rake-wheel planes are vertical and in the third the rake-wheels are inclined to the ground and out of contact therewith. With the rake-wheels in the dotted position, the machine is used for tedding and is drawn in the direction 27 by moving the draw-bar 24 to an alternative pivot 26. In Fig. 4 the machine is pushed by a tractor 32 by employing the drawbar as a strut between a beam 34 and an anchorage 30 on the frame. The beam 34 is pivoted on a stub-axle 42 on the tractor and is connected to a second anchorage 31 on the frame. Specification 968,852 is referred to.

A storage tank 10 has a floating roof 20 with gas inflatable means 28 between the roof and the tank wall 11 and means pneumatically connected at 94 to the inflatable means 28 operable in response to temperature change to keep the gas pressure inside it within predetermined limits. The means 28 is a toroidal tube with an abrasive-proof cover over an inner tube of polyvinyl plastic material. It is fastened at top and bottom to the side-wall of the roof and kept inflated by a regulator 40, 42 mounted on the annular caisson 24 which surrounds the roof. The expansion chamber 40 of the regulator is divided by a flexible diaphragm 84 weighted by a plate 88 which carries an indicator rod 90. The chamber is connected by a pipe 110 to control apparatus 42 comprising three interconnected cylinders 100, 102, 104 which house liquid valves also connected at 120 to a sealed chamber inside the caisson 26 as shown in Fig. 6. When due to changes in ambient temperature and/or pressure the pressure in the chamber 26 is below that of the atmosphere by a predetermined amount the valve 104 operates to supply it with air. The expansion chamber 40 receives air from the chamber 26 through valve 102 or discharges it to the atmosphere through valve 100 depending on the state its pressure relative to the ambient conditions.

Title: Programme loaders for programmable controllers
IPC: G05B19/05
Filed: 1973-08-24
Abstract: 1425251 Automatic control ALLEN-BRADLEY CO 24 Aug 1973 [1 Sept 1972] 40191/73 Heading G3N A program loader for a programmable controller employs a read-write memory which may be located physically within a cabinet for the controller. After a program is developed the readwrite memory may be left in the controller or the program transferred to a read-only memory installed in the controller. The contents of the read/write memory 1 comprise a series of one word instructions stored in successive memory addresses which, during a control operation, are cycled in the controller by an address sequencer 35. Alternatively, a memory address can be manually selected at an address input applied through a memory address counter 28 to select from the read-write memory 1. Finally, the memory address counter can be operated through its up-count and down-count terminals 29, 30 for editing.  Loading of a programme into the memory 1 is  effected through a data-input selector 13 responsive to manual operation and address inputs and decoders 8, 9. Editing in GAP and UNGAP modes is effected by the use of first and second temporary stores 63, 70 operating in conjunction with the counter 28 to transfer instructions stored in the memory 1 from one location to another. In the GAP mode a one line upward address shift is automatically effected whereby an instruction is read out, stored in store 63 zeros written in the addressed line; the stored instruction being transferred to store 70 and the subsequent instruction read into store 63 and the contents of store 70 replaced in the vacant line. This is repeated so that the memory 1 is re-loaded with a gap in the program sequence which can be filled with a new instruction. Alternatively, a line can be erased to leave a gap. In the UNGAP mode is the memory address of an empty line or gap is manually inserted at an input 37 and applied to an address comparator 41. The memory address counter is then out to its maximum count and a cycle of instruction transfer through stores 63, 70 and decrementing of counter 28 is automatically carried out until the count in counter 28 corresponds to the manual input to the comparator 40 at which step the UNGAP operation terminates. These operating modes and SEARCH and MONITOR modes are determined by a control circuit 75 which is described in detail in the Specification. In a TRANSFER mode of operation the program in memory 1 is transferred, when fully tested, to a read-only memory 221 through the input data selector 13 and a transfer circuit 225. The manner of transfer is disclosed in Specification 1384408 [Division G2-G3] the program loader of which differs from that of the present Specification in that it contains its own read-write memory.

Abstract: 1,247,304. Transformers. TAIYO YUDEN K.K. 13 Aug., 1969 [15 Aug., 1968; 17 Oct., 1968], No. 40445/69. Heading H1T. [Also in Division H4] A compensating arrangement for use in compensating for pin-cushion distortion in television receivers comprises an insulated case 15, an open magnetic circuit provided by a flanged ferrite core 5, permanent magnet means 12, 13 providing a biasing flux # longitudinally in the core adjustable by means of screws 17, and two transformers A, B, wound with their primary windings connected in series and secondary windings 10, 11 connectable together in series opposition so that a current passed through the secondary winding can provide in combination with the biasing flux a saturable reactor effect at one of the transformers depending upon the direction of that current. When used to compensate for top and bottom pin-cushion distortion in a television, the vertical deflection current passing through the secondary coil is modified by the horizontal deflection current flowing in the primary by an amount of modification controlled by the magnitude of both currents. Adjustment of the biasing flux allows the amount of compensation with respect to the top and bottom distortion to be varied. In a modification (Fig. 6, not shown), the adjustment of the biasing flux is performed by using a rotatable cylindrical magnet (14) to influence a standing flux (#) set up by the permanent magnets (12, 13).

Abstract: 1,104,727. Tubular heat exchangers. SERCK RADIATORS Ltd. 26 Sept., 1966 [27 Sept., 1965], No. 40975/65. Heading F4S. A heat exchanger comprises a tubular casing 10 with fluid inlet and outlet connections 11, 12 and containing heat exchange tubes 16, at least one tube plate 18 connected to the tube ends, and opening into a hollow end member 13 with an inlet or outlet, 14 or 15 respectively, sealing means being clamped between the end of the casing and the end member. As shown, rubber rings 20 of internal diameter less than the external diameter of the tube plate 18 are separated by a metal ring 22 of wedge-shaped cross-section, and the assembly is clamped between the shell and a flange 19 on the end member 13, which flange is of the same cross-sectional dimensions as the shell. Lugs 23 and 24 are spaced around the periphery of the end members 13 and shell 10 respectively, the lugs 24 being formed by welding to the shell the ends of limbs of U- shaped elements. Screws 25, attached to lugs 23 are tightened by nuts 26, so that rings 20 and 21 are compressed; and because of the wedgeshaped ring 22, rubber is displaced inwardly and exerts a strong sealing pressure on the tube plate 18 to form a joint between shell, end member and associated tube plate. The metal ring 22 may be of T-shaped cross-section (Fig. 2a, not shown), so that while the central web separates the rings 20, 21, the outer flanges prevent their outward expansion on tightening the clamps. Rings 22 are formed with bores 22a so that any leakage past ring 20 or 21 will be vented to the atmosphere.
