Title: Method and means for drying
IPC: F26B23/02
Filed: 1980-05-23
Abstract: A method of drying a surface while blowing a gaseous medium on to the surface comprises blowing on to the surface compressed air, the relative humidity of which is essentially lower than that of the natural air layer immediately adjacent the surface, and heating the drying medium or parts thereof to such an elevated temperature that the surface is permitted to quickly attain a temperature above the dew point but below the temperature at which the surface is adversely affected. The drying apparatus comprises a hollow casing 10, which serves as a handle. The casing has a closed end 17 wherein compressed air is admitted through an air hose 12 with an air valve 13. An air nozzle 13A is provided at the other end of the casing. The nozzle is designed to form a conical or flat air stream. The casing 10 is surrounded by a ring hood 14 having a ring burner 15 for gas. An air slot 18 is formed between the hood and the casing. During operation, compressed air is fed to the nozzle 13A, and by an ejector effect, air is sucked in through the air slot. The compressed air and the sucked-in air are then heated by the gas burner 15. <IMAGE>

Title: Apparatus for delivering liquid to a container to a required level
Inventor: BURGE TERENCE
IPC: H01M50/627
Filed: 1983-02-25
Abstract: Apparatus for filling a battery or other container to a required level from a remote position. The apparatus includes an arm 1 having at one end a filling nozzle containing a level detecting probe 20. The nozzle is engaged with the filling inlet by manipulation of the arm 1 from the remote position. The nozzle 5 is supplied through the arm 1 with distilled water or other liquid under the control of a pressure- responsive flow valve 4. The flow valve 4 is controlled by a controlling pressure, for example compressed air, admitted through a manually-operable valve 16 at the remote end of the arm 1. The probe 20 is connected through the arm 1 to a controlling pressure connection between a normally-open stop valve 18 and the flow valve 16 and also to a valve member in the stop valve 18. When the probe 20 is closed by the liquid having risen to the required liquid level, an increase in pressure closes the valve member of the stop valve 18 and interrupts the transmission of pressure to the flow valve 4 thereby interrupting the flow of liquid to the nozzle 5, despite the manually-operable valve still being held open. <IMAGE>

Title: Hydraulic brake booster
Inventor: STEFFES HELMUT
IPC: B60T13/14
Filed: 1983-03-11
Abstract: A booster piston (8) is sealingly guided in a housing and defines a pressure chamber with its one end face. A pedal-actuatable brake valve controls the auxiliary pressure in dependence upon a pedal force and supplies it to the pressure chamber (12). To avoid the disadvantage that the brake valve must be held to extremely tight manufacturing tolerances since otherwise there occurs undesired great leakage at the brake valve, a pressure-reducing valve (37) is inserted between the auxiliary pressure source (35) and the booster piston (8) in such a manner that a piston (42) of the pressure-reducing valve (37), which piston controls an annular valve passage (48, 49), is acted upon by the auxiliary pressure via a smaller effective area in the opening direction of the valve passage, while it is acted upon by reduced pressure via a greater effective area in the closing direction. A further effective area of the piston (42) is subjected to the pressure in the pressure chamber (12) in such a way that, upon actuation of the hydraulic brake booster (6), a further force becomes effective at the pressure- reducing valve (37) in the opening direction. <IMAGE>
