Abstract: 1,148,410. Hydro-pneumatic suspension units. REGIE NATIONALE DES USINES RENAULT. 21 Oct., 1966 [10 Nov., 1965], No. 47438/66. Heading F2S. In a hydro-pneumatic suspension system for a vehicle comprising a piston 5, having, e.g. a pair of conventional split rings 6 and which works in a cylinder 2 fed e.g. with oil through a pipe 3 and having e.g. a pipe 4 for returning leakage oil to a reservoir, not shown, the piston is provided with a complementary elastic ring 7 which is capable of ensuring a perfect fluid tightness when the vehicle is stationary while permitting leakage of oil when the piston is reciprocated in the cylinder to provide lubrication and lower frictional resistance, the ring 7, made e.g. of rubber or suitable plastics material, having a slightly greater diameter than the cylinder bore, and being received, with a certain axial play, in a groove 8 and leaving an annular space 14 between the inner periphery of the ring 7 and the bottom of the groove 8. In this manner, on an initial upward movement of the piston 5, e.g. when the vehicle is stationary, oil leaks past the rings 6 to fill up the space 14 in the groove 8 and increase the pressure therein the ring 7 being strongly urged radially against the cylinder wall with a force which is greater than the force which urges the lower face 11 of the ring into sealing engagement with the lower face 12 of the groove 8. When the vehicle is in motion each downward stroke of the piston 5 causes the piston to move downwards relative to the ring 7 so that oil can leak from the groove space 14 past a passage 13, between the lower faces 11, 12 respectively of the ring 7 and the groove face 12, and into the normal clearance space between the piston and cylinder. In a modification, Fig. 3, not shown, the ring (7) is constantly urged toward the groove face (12) by a metal spring (16). The spring (16) may be replaced by a resilient plastics ring having radial passages to permit ingress of oil into the groove space 14. This spring may be integral with the body of the ring 7.

Abstract: 1391150 Magnetic heads INTERNATIONAL BUSINESS MACHINES CORP 12 Oct 1973 [30 Nov 1972] 47709/73 Heading G5R [Also in Division H3] Decrease of sensitivity due to oxidization of a magnetoresistive thin film magnetic bubble sensor or magnetic tape reading head is prevented by an overlay of Al 2 O 3  or Si 3 N 4 . The magnetoresistive material may be permalloy, or an alloy of Ni-Fe, Ni-Fe-Co, Ni-Co or Fe-Co, and have a thickness of between 200 and 1000. The overlay may be of twice this thickness. As applied to sensing magnetic bubbles 4, Fig. 1, in a magnetic plate 2, the sensor consists of a permalloy element 10 having an easy axis of magnetization in the direction of current flow from a source 12 through the element. The presence of a magnetic bubble changes the element resistance which is detected by the change of voltage across the source. A layer of a dielectric material S and a sputtered layer 18 of Al 2 O 3  or Si 3 N 4  extend over the magnetic plate and the magnetoresistive element. Similar layers are applied over the reading head 20, Fig. 2, of a moving magnetic tape 22, the magnetoresistive sensor 10 being similar to that shown in Fig. 1.

Title: Methods of compacting concrete or similar masses and vibrators for carrying out the methods
IPC: B06B1/18
Filed: 1971-10-14
Abstract: 1336031 Vibrators WACKER WERKE KG 14 Oct 1971 [14 Oct 1970] 47767/71 Heading F2X [Also in Division B1] Concrete or similar masses are compacted by means of a vibrator which has a housing in which an eccentric mass is caused to circulate through the impingement of a pressure medium, e.g. air, the amount of the pressure medium supplied to the eccentric mass being automatically controlled so that the rotational speed of the eccentric mass when the vibrator is idling does not substantially exceed the value or range of values specified for the vibrator when working under load. In one embodiment (Fig. 1), the eccentric mass is in the form of a ball 2 arranged to roll on a track consisting of two track members 4, 5 in the form of truncated cones. The track member 5 is formed on a sleeve 6 which is movably fitted in the housing 1, resting via cup springs 7 against a fixed part of the housing 1. A control edge 9 on the movable sleeve 6 cooperates with a fixed control edge 11 integral with the housing 1. Compressed air flows via a supply line 8 into a passage 10 in which the control edges 9, 11 are located. The air flows between the edges and impinges tangentially upon the ball 2 which rolls around and between the track members 4, 5. The rolling resistance of the ball 2 on the track is small when the vibrator is idling, i.e. is outside the material to be compacted, and rises appreciably when the vibrator enters into contact with the material when the ball 2 tends to reduce speed. If the centrifugal force exerted by the ball 2 upon the movable track member 5, at a tendency towards rising speed, becomes greater than the counterforce exerted upon the sleeve 6 by the cup springs 7, the movable track member 5 is forced away from the fixed track member 4 and the control edges 9, 11 are moved towards each other, so reducing the cross-section of the passage 10 and hence the flow of compressed air to the ball 2. The control distances and control forces are selected so that the rotational speed of the ball 2 remains constant. A similar but reverse control effect occurs at a tendency towards diminishing speed. In alternative embodiments (not shown), the flow of compressed air is controlled in dependence upon a tendency towards rising or diminishing speed of the eccentric mass by means of a piston carrying a conical valve closure body co-operating with an annular valve seat, a differential piston, and a control ball adapted to vary the effective cross-section of a compressed air duct.

Title: Process and apparatus for transfering heat between glass sheet and a gas flowing in contact therewith
IPC: C03B23/035
Filed: 1964-11-27
Abstract: A process for heating glass sheets to deformation temperature while they are supported on a cushion of gas comprises changing the characteristics of the gaseous support during the heating so that the glass sheets are supported at a <PICT:1108163/C1/1> height above the gas outlets greater while the glass is below deformation temperature than after the deformation temperature has been reached.  After leaving a loading station the sheets are conveyed over a flat bed 20 supported upon a gas which issues from outlets in the bed, flows over the surface of the bed, and exhausts beneath the side edges of the sheets.  The sheets are brought to a deformation temperature of 1200-1350 DEG  F. by the heat from the gases and from auxiliary radiant heaters in the furnace roof.  At a point about 2/3 the length of the heating zone the sheets are conveyed over a bed in which an increasing number of exhaust outlets are introduced intermediate the gas outlets. This causes the support height of the sheets to be gradually reduced from 0.04 to 0.25 inch to 0.005 to 0.020 inch as the sheets approach deformation temperature.  The diameter of the exhaust ports at the edges of the support bed are less than those in the centre of said bed, and the outlets at the surface of the bed are flared outwardly.  To get an even support of the sheets the pattern of the outlets and exhaust holes is varied but caused to repeat every fifth row.  In the heating zone there is provided a wall 43 having a large circular opening in the upper end and a blower 44 fitted in this opening causes hot gases from above the sheets and support bed to be recirculated into a plenum chamber below the bed, formed by baffles 46-48, and thence up through the outlets in the bed.  After reaching deformation temperature the sheets may be bent by passing over a bed having the gas-emitting outlets in a curved surface.  They are then conveyed into a tempering zone between complemental upper and lower blastheads, the lower one being provided with air passages through which air passes to cool and support the sheets whilst cooling air at a lower pressure is also passed through the upper head to assist in the cooling of the sheets.  The bed upon which the sheets are supported has all the characteristics of that disclosed in Specification 1,108,161 and the conveyer is the same as that disclosed in Specification 1,108,162.
