The stator of a synchronous motor comprises a coil (not shown) wound on a core and surrounded by an insulating sleeve 1 having one or more integral projections 2 accommodating the leads of the coil and connections between these leads and respective electrical conductors. These conductors may be the leads of voltagedropping resistors connected in series with the coil, and recesses to accommodate these resistors may be provided in the projection 2, as shown by the broken lines. To facilitate assembly slots 5, 6 are provided in the sleeve and projection so that the coil can be dropped into the sleeve with its leads extending into the slots. The core is tubular and is provided at its end with discs having projecting tongues which constitute polepieces, the tongues on one of the discs being folded back and extending to the other end of the core. One such folded-back tongue passes through a slot 10 in the projection 2. The coil may also constitute the inductance of a D.C. to A.C. converter, in which case the projection is arranged to accommodate leads to the two ends and a centre tap on the coil.

Abstract: 1298818 Separating oxygen from air KOBE STEEL Ltd 18 Dec 1969 [20 Dec 1968 27 Aug 1969] 61677/69 Heading B1L An air refining process using the fixed bed apparatus of Fig. 1, comprises feeding air to a moisture and carbon dioxide adsorbing system of beds 104, each containing a moisture adsorbing layer a and a carbon dioxide adsorbing layer b and each undergoing a cycle of adsorption, heating, regeneration and cooling and then feeding the resultant product to a nitrogen adsorbing system of beds 105, each undergoing a cycle of adsorption and regeneration. In practise air is fed via dust catcher 100 and blower 101 to moisture and carbondioxide adsorber A, the product then passing via line 112 to nitrogen adsorber E, valves VE-1 and VE-1# being open and valves VF-1 and VF-1', VE-2 and VE-2' being closed. The ensuing oxygen from adsorber E passes through line 114 and is split into two paths, viz (1) to effect cooling of adsorber B, and then to cooler 107 and desicator 106 back to line 114 and (2) to regenerate adsorber C and thence to exit 113. Adsorber F is on regeneration at this time with valves VF-2 and VF-2' open to vacuum and valves VF-1 and VF-1' closed. The desorbed nitrogen is passed via line 118 and heater 108 to heat adsorber D, emerging gas then exits at 115. Oxygen, can also be obtained via line 120. The adsorbents used are silica gel and alumina gel and natural or synthetic zeolites. In another embodiment the moisture-carbon dioxide adsorbing beds and the nitrogen adsorbing beds take the form of two rotating adsorbers, e.g. 4-1, 4-2, which show the former. The adsorber comprises a rotatable cylinder 5, Fig. 4-2, upper and lower covers 17, an adsorbing section A comprising segments 3, Fig. 4-1, enclosed by partitions 2, gauzes or perforated plates 6, 7. Gas distributing chambers B', B are divided into three and four sections respectively by vertical and horizontal plates 10, 11 so that the correct gas can flow from a section of the chamber B' through the bed A and out via the corresponding correct section of chamber B. Rotation of the cylinder causes the refining cycle to repeat with the functions of the bed segments changed.

IPC: B66C13/18
Abstract: 664,373. Load-handling machines; hoists; vehicle fittings for loading. MOTT, S. F. Aug. 31, 1949. [Sept. 8, 1948] No. 23669/48. Classes 78 (iii) and 78 (iv). Apparatus for transferring loads comprises a frame and a telescopic strut hinged at opposite ends of a base and means for suspending a load from the frame, the frame, the strut and the base forming in one position a triangle with an obtuse angle between the frame and the base, and means to move the frame to and beyond a vertical position to allow the strut to collapse and form with the frame and the base a substantially isosceles triangle. As shown, the apparatus is mounted on an agricultural trailer comprising a chassis 1 on wheels 2. The trailer has a winding drum 4 on a shaft 3 which may be driven from a shaft on a tractor which hauls the vehicle. The hoist comprises two members 5 arranged as a triangular frame hinged at its base 8 to one side of the trailer and pivoted at its apex 9 to a telescopic strut 10 comprising a steel rod 11 sliding in a cylinder 12 pivoted at 13 to the other side of the trailer. A piston head 14 on the rod 11 permits the cylinder 12 to form a pneumatic shock absorber. A rope 16 passes from the drum 4 over a pulley 15 supported from the pivot pin 9 and may support a skip 17. When extended the strut 11 supports the frame S in a position overhanging the side of the trailer. The rope 16 may then be hauled in to raise a load such as the skip 17 until a stop 19 on the rope 18 engages the pulley 15 so that further winding of the rope 16 raises the frame S until it falls under gravity to the position shown in which the strut 10 is fully collapsed. The collapsing of the strut 10 may be caused to operate a clutch to permit the skip to turn upside down and release its load. The drum 4 and rope 16 may be employed to draw a carriage 18 supporting the loaded skip to the side of the vehicle.

Abstract: An opto-electronic apparatus for reading out information coded in a card as a pattern of alternating transparent and opaque areas which are subjected to infrared radiation whose passage or non-passage is detected by suitable detectors. The process of reading out the information contained in the data carrier is timed or clocked by a clock cycle generated from a clock track contained in the data carrier itself or the data may be self clocking. The apparatus includes a program memory 37 which contains stored information regarding the clock cycle to be expected and is able to read out the information without using automatic mechanical transporting devices. If the manual insertion of the card of the data carrier includes generally unintended in excessive reverse motions, the circuit remembers the last clock cycle and continues to read the data at that point during subsequent forward motion. The apparatus has a standby operation using low power sensing pulses and a switchover to data read- out in the presence of the data carrier with high powered pulses of a current density which exceeds that normally acceptable to the light sources under continuous operation.
