Abstract: <PICT:0752517/III/1> A drying machine for the continuous production of sheet soap comprises a standard supporting a reel of paper to be coated with soap, a soap bath, a standard for the driving and winding mechanism for the finished sheet, and a tunnel type drier through which the coated sheet passes and which is heated by electric resistances and within which, by means of blowers, air streams are caused to flow to ensure drying of the sheet.  As shown, the reel of paper 2 is freely supported on a standard 1 adjacent to the soap bath 3, which is provided with a cylinder 4, journalled on a bearing 5 and dipping in the bath, around which the paper sheet N passes as it is unwound from the reel 2.  At the outlet of the bath, the sheet passes between rollers 6, 7 which are adjusted to control the thickness of the soap layers.  The tunnel type drier is horizontal and is divided into two sections, 8, 9, maintained at different temperatures, through which the sheet N travels unsupported.  The dried sheet leaves the tunnel and passes round an idling roller 10 to a winding-up cylinder 12 driven by a motor 13, the rollers 10 and 12 and the motor 13 being supported by another standard 14.  The tunnel drier is preferably double-walled and heat insulated.  Along the inner horizontal walls of the tunnel electric resistance units are arranged and are supplied with current to provide a preferred temperature of 100-120 DEG C. in the section 8 and a temperature of 200-220 DEG C in the section 9.  A wire safety net may be positioned above the bottom heaters.  Two air streams generated by blowers 20, 21 are admitted through ducts 18, 19 to the tunnel so as to skim both sides of the sheet N and assist in its drying.  The warm air flows to the inlet end of the tunnel and is returned through a duct branching into two ducts to the blowers 20, 21 to form a closed circuit.  At a certain humidity the air may be discharged through a stack 25 controlled by a gate 26.  A third blower 27 for cooling the sheet may be provided.

Title: Improvements in or relating to control apparatus for engines for ship propulsion
Filed: 1937-07-13
Abstract: 498,825. Speed control of engines for ship propulsion. SULZER FRERES SOC. ANON. July 13, 1937, No. 19359. Convention date, July 14, 1936. [Class 114] [Also in Group XXVI] A control mechanism for engines of ships comprises a centrifugal governor l driven by the engine and a lever c connected by a link d to a lever e connected to the regulating means of the engine. The pin i on the lever c forms the fulcrum of the lever m connecting the governor sleeve n and the link q which is also connected to the lever e. The links d, q have slotted ends h, p respectively and the lever e is biassed in the direction for maximum speed by a spring k. Movements of lever c through link d cause speed variations and the simultaneous variation of the fulcrum i causes the pin o to take up a position distance s from the end of the slot p that is practically constant for all speeds so that should the propeller leave the water the engine speed increases by a substantially constant amount before the pin engages the link q and the governor moves the lever e against the spring k to reduce the motive power medium. In Fig. 4, the same object is achieved by arranging that the speed is varied by rotating the hand wheel r which engages the abutment u and engages left- and right-hand threads on the rods q, t. The pin w on the lever w engages a slot v in the rod q. In a further modification it is arranged that the hand lever varies the spring loading of the governor.

Title: Method of and means for producing fine bubbled foam for fire extinguishing purposes
IPC: A62C5/00
Filed: 1930-06-27
Abstract: 357,639. Foam-making. SANDOR, N., 92, Lancaster Gate, London. June 27, 1930, No. 19579. [Class 47 (ii).] Relates to that method of producing foam wherein air is forced by a pump through a distributing body immersed in a foam-forming liquid in a closed vessel, and consists in carrying out the foam production under a pressure less than atmospheric. The distributing body 6 is connected to atmosphere by a suction pipe 8. Each cylinder 12 of a two-cylindered pump has a suction valve 12 communicating with the air space 3 of the vessel 1 and a discharge valve 14 communicating with a foam delivery passage 5, 15. By this arrangement, operation of the pump produces a pressure lower than atmospheric in the space 3. This causes air to be drawn in by the pipe 8, and prevents undue expansion or bursting of the foam bubbles when the foam is discharged. A constant level of liquid is maintained in the vessel 1 by a reservoir 11 and float valve 10. The apparatus may be used for pumping water alone, by closing the pipe 8 and opening a water inlet 17. A water trap is preferably provided in the discharge passage 15.
