Title: Motor vehicles embodying an arrangement for damping steering wheel vibrations
IPC: B62D1/04
Filed: 1975-10-14
Abstract: 1481770 Motor vehicle suspensions VOLVO AB 14 Oct 1975 [15 Oct 1974] 41913/75 Heading B7D The suspensions of the left and right steerable front wheels of a motor vehicle have different longitudinal stiffnesses so that transmission of vibrations to the steering wheel of the vehicle due to imbalance or ovality of the wheels is reduced because resonant vibration occurs at different speeds for the two wheels. In a vehicle having each front wheel carried by a suspension arm connected to the vehicle by spaced bearings defining a longitudinal pivot axis one of the bearings is located in front of or behind the wheel axis to carry longitudinal wheel loads and has different dimensions or is made of different materials for the respective wheels. The suspension arms themselves may alternatively be made with different degrees of resilience in the longitudinal direction of the vehicle.

Title: Tray spacing conveyor
IPC: B65G47/26
Filed: 1970-09-03
Abstract: 1277978 Endless conveyers GORDON JOHNSON CO 3 Sept 1970 [22 Jan 1970] 42130/70 Heading B8A Trays 10 supported on rollers 38 of endless conveyer chains 36 are mutually spaced by devices 56 pivotally supported on pedestals 58. The upper run of chains of the conveyer is unsupported but, below the spaces between succeeding devices 56, there are pads 50 which frictionally engage the rollers 38. The rollers of the lower run are continuously supported on tracks 40. The spacing devices 56 are normally biased anticlockwise due to their sections 64 being longer and heavier than their sections 66. A tray fed from a belt conveyer 82 and a driven roller 84 passes on to the rollers 38 which, as they engage the first of the pads 50, are rotated momentarily and cause acceleration of the tray. The tray then depresses a portion 74 of the first spacing device 56 and a portion 68 is raised to stop the next succeeding tray. Simultaneously, the leading tray is accelerated by the rollers' 38 engagement with the underlying pad 50. When this tray clears the portion 74 of the device 56 the stop portion 68 is lowered and the next tray is able to proceed. At the discharge end of the conveyer alternate trays may be transferred in opposite directions by mechanisms 12, 14 under the control of a switch 104. As long as a tray remains on the portion 74 of the last device 56 all upstream devices 56 remain tilted clockwise and all preceding trays will be retarded. The trays are guided by a pair of members 88 whose spacing is adjustable by threaded shafts.

Abstract: 1399499 Automatic control of position ROHR INDUSTRIES Inc 11 Sept 1972 [21 Jan 1972]  42161/72 Addition to 1385212 Heading G3R The magnetic suspension and propulsion system described in the Parent Specification employs a modified feedback circuit as shown. In this modification the output of the square root circuit 24" is used directly to multiply the output of the speed controlling oscillator. The outputs of multipliers 120 ... 122 are multiplied by the position transducer signal to provide a term in the control signal which is proportional to the resistive aspect of the suspension windings, and they are also differentiated to provide a term proportional to the frequency of the supply to allow for the reactance of the winding. The Specification sets out the mathematical aspects of the control; the equation which the system solves is the same as that for the Parent Specification 1385212.

Title: Depilating hides and/or skins
IPC: C14C1/06
Filed: 1963-10-31
Abstract: In depilating animal hides and/or skins, they are brought into contact with an alkaline aqueous liquor, e.g. at a temperature between 70 and 80 DEG  F., in the form of an aqueous solution or lime slurry comprising a compound containing phosphorus and sulphur, which is hydrolysable to furnish sulphydrate ions in the liquor. The hides and/or skins are kept in the liquor for a time sufficient to effect substantially complete loosening of the hairs, and are then passed through a conventional depilating machine.  Preferably, the atomic ratio of sulphur to phosphorus in the compound should not be less than 5:2.  Suitable compounds are: phosphorus pentasulphide, phosphorus polysulphides such as P4S24, and alkali metal thiophosphates, such as sodium thiophosphate. The amount of the compound in the liquor may be between 0.1 and 10.0, by weight of the hides and/or skins.  The solution may contain sufficient alkaline substance, such as sodium sulphydrate, sodium hydroxide, potassium hydroxide, or sodium sulphide, to keep its alkaline pH value substantially constant. The mole ratio of sodium hydroxide to phosphorus pentasulphide in the solution may be between 5:1 and 8:1. According to Example 8, the depilating solution may contain: sodium thiophosphate and trisodium phosphate or sodium carbonate; sodium thiophosphate, trisodium phosphate and ammonium hydroxide; or sodium thiophosphate ammonium hydroxide and sodium carbonate.  Before being treated with the depilation liquor, the hides and/or skins may be soaked in water or in an aqueous solution containing up to 2 per cent of their weight of an alkali metal sulphydrate, such as sodium sulphydrate and/or an alkali metal tetrasulphide, such as sodium tetrasulphide.
