Abstract: 445,764. Spray-producers. DE VILBISS CO.. 3600, Detroit Avenue. Toledo, Ohio, U.S.A. Dec. 16, 1935, No. 34869. Convention date, Dec. 15, 1934. [Class 69 (iii)] In a spray head for delivering flattened jets of spray of the kind in which flattening air jets impinge on the spray formed from a central air supported stream of liquid and atomized by impinging air jets, the flattening is effected by two converging jets on either side of the central jet impinging on the spray. The Figure shows a form in which a central liquid jet delivered through a central nozzle and supported by air from an annular nozzle surrounding the central nozzle is atomized by jets of air delivered through orifices 10, 11 impinging against it and flattened by jets delivered from orifices 16, 17 and 18, 19. The jets from the pair of orifices on each side of the central jet coalesce to form a flattening stream of air. Modifications are shown in which the atomizing jets are mounted in pairs either vertically or horizontally arranged on each side of the central jet, and also groups of four or six atomizing jets equally spaced spaced around the central jet.

Title: Improvements in electric control systems
IPC: G05B1/02
Filed: 1946-11-26
Abstract: 643,013. Automatic speed control systems. BRITISH THOMSON-HOUSTON CO., Ltd., and STOKES, J. A. Nov. 26, 1946, No. 35051. [Class 38 (iv)] [Also in Group XXXVII] In an electric control system in which the angular velocity of a device is determined by the equal displacement of two points along opposite sides of a resistance bridge having a polarizing voltage across one diagonal, a voltage is fed back from the controlled device to the other diagonal of the bridge so as to produce a non-linear relation between displacement of the points and angular velocity of the device; Potentiometers 1 and 2 together with resistors 3, these latter being all of equal value, form the normally-balanced bridge having a polarizing voltage across diagonal AB. The sliding contacts 10, 11, supply, through an amplifier 4, the field of a reversible motor 5 which is coupled to a tachometer generator 8 feeding back to the points C, D a - voltage proportional to the actual angular velocity. Resistance 13 represents the internal resistance of the generator. The voltage fed back may, alternatively, be obtained from the armature of the motor. It is shown that the ratio of the rates of change of angular velocity with displacement of contacts 10, 11, at zero displacement and at maximum displacement is given by R 2 <SP>2</SP>/(R 1 +R 2 )<SP>2</SP>, where R 1  is the resistance of each half of the potentiometers and R 2  is the value of the resistors 3.

Abstract: 1,274,544. Producing corrugated laminates by extrusion. MITSUBISHI KASEI KOGYO K.K., and S. AKAMATSU. 14 July, 1969 [18 July, 1968; 26 Aug., 1968; 17 Sept., 1968 (2)], No. 35270/69. Headings B5A and B5N. To produce laminated plastics sheet material having a corrugated layer, a plastic sheet 10 is delivered from an extruder 11 to the nip between corrugating rollers 12, 13 and a second plastics sheet 14 delivered from an extruder 15 is brought into contact with the corrugated sheet by means of a roller 16, adhesion between the sheets being due to residual plasticity in newlyextruded sheet 14. Subsequently as shown, a second extruded sheet 23 may be applied to the corrugated sheet in a manner similar to that of sheet 14. A multi-layered product may be produced by initially bringing together a number of corrugated sheets with the corrugations of adjacent sheets crossing one another and then applying flat sheets to opposite sides of the assembly. The materials of the sheets may differ and in this case particles of a substance such as calcium carbonate may be sprinkled on the flat sheet material to aid adhesion. Plastics specifically mentioned are polyethylene, polypropylene, polystyrene, P.V.C. and polyvinylidene chloride. The sheets may be foamed. In the apparatus, corrugating rollers 12, 13 are temperature controlled, the temperature of roller 13 being maintained above that of roller 12. Such temperature control in effect cools sheet 10; this cooling may be supplemented by a water spray while sheet 10 is on roller 13. Sheet 14 is cooled by roller 17. Sheet 23 is brought into contact with corrugated sheet 10 by passage through the nip of rollers 20, 21 the former being maintained at a higher temperature than the latter. To prevent distortion when sheet 23 contracts on cooling a band 22 which applies tension to sheet 14 and roller 20, rotating as shown, increase the distance between the corrugations at the point of application of sheet 23. This sheet is cooled by an air jet from nozzle 27 and sheet 14 is further cooled by contact with a cooler 26. In a modification, Fig. 2 (not shown), the peripheral length of roller 21 in contact with the laminate is effectively increased by the provision of a guide roller 28. The sheet material used may be of film thickness.
