Filed: 1938-11-02
Abstract: 520,893. Hanging - rods for sheet articles. SHIPWAY, S. P., and WHITBYS, Ltd. Nov. 2, 1938, No. 31765. [Class 52 (v)] [Also in Group XXV] Articles of sheet form such as eiderdown blankets are supported for display or storage by clamping one edge between a flat wood bar 1 and a rod or tube 6 received in wedge-shaped slats 5 in sheet metal clips 2 attached to the ends of the wood bar by screws or rivets 4. Preferably the clips are adapted to receive a rod 6 on each side of the wood bar. The bar may be carried on a vertical post 7, with a stay 8, the post being adapted to, rotate in sockets. Another form adapted for suspension by a central hook from a rail track &c. comprises a wood bar 9, Fig. 6, tapered towards each end and preferably recessed at the sides at intervals to reduce weight, with metal clips 13 at the ends to receive a rod or tube 14, Fig. 9. The shape of the wood bar enables the rod or tube to be sprung into gripping engagement at the centre. The metal clips are shaped to induce a wedging action and have lugs 16 to prevent the rod or tube from falling out when no article is being supported.

Abstract: 783,587. Mixing fluids in flow. STABILIMENTI ELETTROMECCANICI RIUNITI ANSALDO-SAN GIORGIO SOC. PER AZIONI. Nov. 8, 1955 [Jan. 15, 1955; Sept. 10, 1955], No. 31885/55. Class 86 [Also in Groups XVIII and XIX] In dispenser-meter apparatus for delivering mixtures of petrol and oil in preselected proportions, pumps 4, 5 suck petrol and oil respectively from their tanks and deliver the fluids to a mixing chamber 22 in a dispensing gun 21, meters being provided to indicate the quantity of fuel and oil, both separately and admixed, and the price of the mixture on the base of preset unit prices. Petrol from the pump 4 passes through an air-trap 7 to a piston valve distributer 24, causing rotation of a shaft 26, and then flows through a membrane stop valve 11, pilot fan-wheel 12, and through flexible piping 13 to the dispensing gun 21. Similarly oil from the pump 5 is delivered to an air trap 15 and then passes through a piston valve distributer 17, causing rotation of a shaft 27, and then flows through a membrane stop valve 18, pilot fan-wheel 19 and flexible piping 20 to the dispensing gun 21. The mixing ratio is pre-set by rotation of a knob 114, Fig. 4, by which the appropriate gear ratio between shafts 26 and 27 is engaged. The knob 114 is integral with a slotted cam 115 which is engaged by the ends of a rocking lever 117 which are attached by rods 118, 119 to clutches in the drives to the pumps 4, 5, so that in the extreme positions, when there is no output required from one of the pumps, the drive thereto is disconnected. Also in these extreme conditions, detents 111, 120 in the gearing hold the appropriate shaft 27, 26 stationary. Meters 221, 222 indicate the separate total volume of oil and petrol delivered, the motions of shafts 27 and 26 being transmitted through shafts 218, 212 respectively for the purpose. The motions of shafts 218 and 212 are transmitted through gearing 224, 223 to a differential 225 which sums the volume of each individual dispensing operation and the resultant motion is transmitted through shaft 228 and gears 229, 230 to counting wheels 31 which can be set to zero at the end of each dispensing operation. A helicoidal coupling 232 and gears 33, 34 transmit the motion of shaft 228 to a totalizator 35 which records the total volume dispensed for all dispensing operations. Gear sets 29, 30 are provided on shafts 218, 212 respectively whereby gears 36, 37, 38 may be meshed according to the appropriate unit current prices of oil and petrol respectively. The cost of each dispensing of each liquid is summed on differentials 39 and the total cost is then summed on a central differential 40 and the result transmitted through gearing 41, 42 and shaft 43 to counting wheels 44 which indicate the total cost of each dispensing operation. A helicoidal coupling 45 and gears 46 actuate a totalisator 47 on which the total cost of all dispensing operations is recorded.

Abstract: 1,016,345. Rotary hydraulic motors. HARTMAN MANUFACTURING CO. Aug. 15, 1963, No. 32222/63. Heading F1F. A rotary hydraulic motor comprises an inner stator 11, Fig. 1 (not shown) and an outer rotor 10, the stator 11 having vanes 28 and the rotor having rollers 33 rotatable therein and each having a cut out formed in it to allow it to pass over vanes 28, the stator having a first fluid passage 69, Fig. 2 (not shown) extending from outside the unit and having a passageway at each opposite side of each of said vanes e.g. 76, 83 extending from passage 69 to work chamber 32, the passage 69 containing a valve member 66 for selectively braking or rotating the rotor. As shown, fluid from pump 19 flows through pipe 22 into passageways 78, 79, 81 and hence through passageways 82, 83, 84 into working chamber 32 to exert pressure against rollers 33 which are fluid tight against surface 27 of the stator. This pressure causes the rotor to rotate in direction A (Fig. 1). When the rollers 33 move out of fluid tight engagement with surface 27 then the fluid will leave through passageways 74, 76, 77 and 71, 72, 73 into bore 67 and hence leave the unit by pipe 23. The rollers rotate by means of gearing 63 which rolls round stationary gear 62 attached to the stator. Valve member 66 is rotatable within passageway 63 such that clockwise movement as viewed in Fig. I will decrease torque and increase the speed of the motor and anticlockwise movement will brake the motor. Pockets 38 are arranged as shown around rollers 33 and fluid under pressure enters said pockets to counterbalance the pressure on the rollers in work chamber 32. C-shaped seals 106 are fixed within rotor pieces 14 and 17 to encircle each end of each roller.
