IPC: G01G23/365
Filed: 1957-11-15
Abstract: 850,329. Weighing apparatus. AVERY Ltd., W. & T. Nov. 10, 1958 [Nov. 15, 1957], No. 35599/57. Class 40 (1). The self-balancing potentiometer circuit of the parent Specification is modified by the addition of means to enable a second amount, proportional to the first, to be weighed out. To achieve this the bridge circuit has four additional resistors RA, RB, RC, RD to vary the input voltage to the Kelvin-Varley potentiometer at ED. The first weighing is carried out with S5 in its upper position, giving reduced voltage to the potentiometer, which is then balanced as before. S5 is then moved (manually or automatically) to its lower position to cut out resistors RC, RD and thus increase the voltage to the potentiometer and energise a relay RL4 which controls the feed of the second quantity being weighed. The potentiometer is meanwhile being driven to balance at a new position, and when this is reached contact Q is opened to stop the feed.

Abstract: 364,767. Variable speed gearing. MALVERN, C. F., Craven Lodge, Quarry Road, Heswall, SHAW, T., 18, Woodchurch Lane, Prenton, Birkenhead, and WOODWARD, A., Hatton Rock, Rock Avenue, Heswall, both in Cheshire. Nov. 28, 1930, No. 35798. [Class 80 (ii).] An epicyclic train 16, 17, 33, Fig. 1, is controlled by an arresting piston oil pump 3 so as to drive a shaft 2 at a speed automatically variable with the load, and by changing the connections, a reversed controlled drive is obtained. A friction clutch 38 splined on the shaft 2 is normally held by a spring 39 against a clutch surface 35 secured to the carrier 18 of the planet gears 17. The sun gear 16 is fast on a driving-shaft 1. The annulus 33 is connected by a gear pair 32, 23 and clutch 25 to the crank shaft 5 of the pump. When a vehicle driven through the gearing is on the level, the shaft 5 and annulus 33 are stationary, and the planets 17 rolling on the annulus drive the shaft 2 forwardly at high speed through the clutch 38. When the resistance increases as in climbing a hill, the shaft 5 slips round and the speed of the shaft 2 falls. To effect reversal, a pedal 27 is depressed which shifts clutch 38 into engagement with a clutch surface 42 connected to the annulus 33, and at the same time shifts clutch 25 so as to connect to the shaft 5 a gear 21 connected through a wheel 20 to the carrier 18. Carrier 18 being arrested, the annulus and the shaft 2 turn backwards. The arresting device comprises single-acting pistons 7, Fig. 2, which in their descent force oil out through spring-loaded valves 10, Fig. 1. As a piston 7 rises, oil is readmitted from the casing 4 through holes 48, Fig. 2.
