Abstract: 274,644. A.M.A.C., Ltd., and Comery, W. July 22, 1926. Control mechanism. - In a twist-grip control for motor-cycles &c. of the type in which the cable or other transmission member is operated through a slide actuated by a pin and helical slot or equivalent mechanism, a motion-multiplying device, such as a lever, is employed between the twist-grip and the transmission member, in order that the helical slot may be of small pitch, whereby reverse movement of the grip under spring action is prevented without the use of a friction device. The helical slot is formed in the thickened walls of the inner end of the metal sleeve of the twist-grip 3, and is engaged by a depending pin 22 on a lever 18 pivoted at 19 on the upper surface of a housing 8, the free end 20 of the lever engaging a recess in a slide 15, which moves along a groove 14 in the housing 8 and is provided with a recess to receive the terminal block of the transmission cable 23. The lever and slide are enclosed by a detachable cover, which is held in place by a screw forming the pivot 19. The housing 8 is fixed to the handle-bar 6, and forms an end abutment for the twist-grip.

Circulating fluids through materials.-An extractor or dyeing-apparatus comprises a vessel a having a perforated partition c, on which the material to be dyed or extracted is packed, and from which extend short perforated tubes c<1>. Below the partition c is a partition d having a central opening e closed by a float-operated valve e<3> Tubes i, j, which pass through the partitions c, d, are provided respectively with internal valves i<2>, i<3> and external valves j<2>, j<3> closing openings i<1>, j<1> at each end of the tubes, these valves being mounted on stems i<4>, j<4> and actuated by floats i<5>, j<5>.

A tube k closed by a non-return valve k<1> extends from the bottom of the lower part cf the chamber into the upper part. In operation, liquid is admitted to the lower part of the receptacle, and, the various valves being consequently placed in the positions shown, the fluid is forced up through the pipe k on to the material h. The floats i<5>, j<5>, e<3> then fall, the valves i<3>, j<2>, k<1> are closed, and the valves i<2>, j<3>, e<2> opened, with the result that the pressure is transferred to the upper side of the partition c, and the liquid is forced through the material until the floats again operate the valves.

Title: Improvements in the predicting of icy conditions on road and like surfaces
Inventor: PRICE WILLIAM IDRIS JAMES
IPC: G01N27/04
Filed: 1961-05-23
Abstract: 966,769. Detecting icing conditions electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 23, 1962 [May 23, 1961], No. 18523/61. Heading G1N. Ice formation on roads is predicted by measuring changes in electrical conductivity due to changes in thickness of a film of water on the road, or a similar adjacent surface, measuring the road surface temperature, and using these measurements to produce an output signal when a predetermined rise in conductivity occurs simultaneously with a road surface temperature near freezing point. The resistance between electrodes 11, 12, embedded in the road surface, indicates the wetness of the road surface and operates relay R2 to close contacts S2 at a predetermined wetness. Contacts S1 are closed when a temperature responsive device in or near the road surface indicates temperature near freezing point, thereby energizing relay R6 to energize a road heating circuit (not shown), Qr alarm circuit (not shown), through contact S6. If a road heater is provided a second heater 24 is simultaneously energized through contacts S<1>6. Conditions conducive to hoar frost formation may be detected by measuring the temperature difference between the road surface and the air, relay R6 operating whenever the road surface temperature is near freezing point and below the air temperature. Snow is detected using asphalt block 20 in which are embedded heater wire 24, pilot heater 23 and, at the surface, electrodes 21, 22 which are connected in parallel with electrodes 11, 12. Pilot heater 23 is energized to melt snow in the centre of the block and the resistance between electrodes 21, 22 controls relay R2. Alternatively, block 20 may be omitted and the pilot heater arranged under electrodes 11, 12. A further alternative is to omit contacts S3 and use block 20 for frost detection. In this case pilot heater 23 is energized periodically (e.g. 15 minutes per hour) and the block is thermally insulated from the road so that between heating periods it cools more rapidly than the road and dew or frost is deposited on it first, the frost being subsequently melted. Relay R6 may also be operated via contacts S4 when the temperature beneath the road surface approaches freezing point. Contacts S5 are for manual control. The device may be automatically disabled if de-icing chemicals lower the resistance between electrodes 11, 12 below a certain value. The apparatus is preferably fail-safe.
