Abstract: 899,070. Coin-freed liquid-dispensing apparatus. GASKELL & CHAMBERS Ltd., [trading as NON-DRIP MEASURE CO.]. Dec. 8, 1960 [Dec. 10, 1959], No. 42052/59. Classes 27 and 116. A coin-freed dispenser for milk or other beverages has a storage vessel 1 provided with a tap 2 which is held open for a predetermined delivery period by a motor-driven cam 14 and an air vent pipe 9 of small bore extends from a cover-plate 5 to the bottom of the vessel so that the entering air meets a counter pressure caused by the head of liquid and, as this counter pressure reduces as the liquid level falls, it compensates for the reduced delivery that would result from the reduction in liquid head. An inserted coin starts up a motor 11 which drives the cam 14 through reduction gear 12 and the cam moves a follower 15 on a lever 16 so that a push rod 17 opens the tap; after one complete revolution of the cam, the tap closes again and a measured quantity has then been delivered through a spout 2a to a container on a shelf 18. The pipe 9 may be placed exteriorly of the vessel 1 or be moulded integrally with the wall of the vessel and may be provided with a spring-loaded non-return valve at the bottom end to prevent liquid rising in the pipe. The quantity delivered may be varied by changing the cross-sectional area of the discharge passage 22 or by adjusting the effective length of the push rod 17. The vessel has a lower compartment for a refrigerator coil and a paddle-type agitator, as described in Specification 856,981, and the filler cap 7 is maintained air-tight by a screw or other clamping means.

Title: Method and apparatus for the determination of the maximum usable braking effort
IPC: B60T8/66
Filed: 1974-10-03
Abstract: 1478408 Friction measurements ERNST LEITZ WETZLAR GmbH 3 Oct 1974 42911/74 Heading G1S The maximum torque that can be transmitted between the wheels of a vehicle and the road is derived from signals representing the wheel slip and the braking or tractive torque during a period of normal vehicle travel. As shown in Fig. 1, the vehicle speed is determined by means of an optical image correlator device, Fig. 2 (not shown), the wheel rotational speed by transducers 4 and the wheel torque by transducers 5. Circuit 2 operates to calculate the wheel slip from the vehicle speed and wheel rotational speed, and to derive the maximum transmissible torque from the slip and torque. Instead of measuring the torque directly, it may be derived at 2 from changes in the vehicle speed. The vehicle speed and wheel rotational speed may be derived from a single optical image correlator, Fig. 3 (not shown). The signals representing the maximum transmissible torque may be indicated at 3 and pass to a control means arranged to initiate braking if the vehicle speed is too high for the prevailing conditions.

Title: Dual column gas chromatograph and method for analysis
IPC: G01N30/46
Filed: 1960-12-28
Abstract: A process for analysing a sample by gas chromatography uses a first and a second column in conjunction with a carrier gas inlet, a detector and a vent line, and includes the steps of: directing the flow of carrier gas through the first column, the second column and the detector in that sequence, and then injecting a sample into the stream of carrier gas ahead of the first column and continuing passing the carrier gas until the lower boiling constituents of the sample have been eluted from the first column and have entered the second column, and then changing the pattern of flow so that the carrier gas is directed through the first and second columns and the detector in a different sequence and optionally different direction, the flow through the detector occurring after the flow through at least one of the columns.  A modification of the process includes the use of two detectors and a further switch valve.  The change of flow pattern is effected in an apparatus comprising a valve having a body provided with six ports for connecting the various elements of the device including inter alia two columns and a detector or detectors, combined with co-operating movable, e.g. rotary, member having six ports coupled in pairs by passages, the ports in the two members being angularly so spaced that in each position of adjustment the ports of the two members will register with each other.  The invention is described with reference to diagrams which also show the use of a six port valve adapted for use as a constant volume sampling valve.
