Title: Air-humidifying apparatus
IPC: F24F3/14
Filed: 1946-03-11
Abstract: 616,986. Automatic control systems. BAHNSON CO. March 11, 1946, No. 7534. Convention date, Aug. 23, 1945. [Class 38 (iv)] [Also in Groups XII and XXXVII] Humidity; temperature.- In air humidifiers mounted in a duct through which a fan drives an air current, the amount of water sprayed is controlled in response to temperature and humidity within an enclosure, the fan speed also being controlled in response to the temperature. A duct 16 having inlets for outdoor air and recirculated air with louvres 20, 21, respectively adjustable in opposite sense in dependence on a thermostat 25, contains a fan 17 and an atomizer 19; grid or other means for reducing the rotary component of the airstream and a spray eliminator may also be included. By means of a mercury switch 29 mounted on the crankarm of a motor 22 actuating the louvres, a relay 28 is energized from a control line 30 when temperature is high to cause a high-speed winding 26 of the fan motor 18 to be connected to a power circuit 32; at low temperatures, the low speed winding 27 is in circuit; or the fan motor may be directly affected by a thermostat. To increase the water flow when the fan speed is high, a second relay 40 affected by switch 29 energizes a solenoid valve 38 supplying highpressure water through a reducing valve 39 to the atomizer, water otherwise passing through a reducing valve 36 delivering at a lower pressure. The main water supply valve 35 is controlled in dependence on room humidity by means of a humidistat 42. In the form shown, three switches 43, 44, 45 are operated in sequence when relative humidity progressively falls below a desired value successively to open valve 35 and energize the atomizer motor through leads 58, open valve 38 to increase the rate of water supply, and finally energize relay 28 so as to increase the fan speed, thus overriding the control by the thermostat.

The ammonium or amine salts of the copolymer are soluble in aqueous liquids and the solutions are useful as stoving lacquers.  A thermosetting, water-soluble melamine or urea-formaldehyde resin may also be included in the solution.  The aqueous solutions of the ammonium or amine salts of the copolymer may be prepared by copolymerizing the comonomers in the proportions specified, in an anhydrous organic solvent which is in contact with a free radical forming catalyst to produce a solution of the copolymer, removing the solvent at least partially after or while adding water and a less than equivalent quantity, as calculated on the carboxyl groups of the copolymer, of ammonia or an amine with a boiling-point below 170 DEG  C., the solutions having a pH value of from 6.6 to 7.4.  In the examples, monomers used are: (a) N-methoxy methyl acrylamide, (b) butyl acrylate, ethyl acrylate and 2-ethylhexyl acrylate, (c) styrene, (d) acrylic acid, (e) 2-hydroxypropyl methacrylate, and trimethylolpropane-diallyl ether, and (f) acrylamide.  The solvent used is n-butanol and tert. dodecylmercaptan is employed as a chain terminator. The catalyst used is cumene hydroperoxide and the salts are formed using ammonia or dimethylethanolamine. In a comparative example, N-methylol acrylamide is used instead of the N-methoxymethyl acrylamide.  The viscosities of the polymer solutions may be increased by the addition of ammonia or amines or glycol ether alcohols.  The solutions are pigmented with titanium dioxide, butyl glycol is added to avoid bubble formation and the lacquers sprayed on to various substrates and stoved. A water-soluble melamine-formaldehyde resin is incorporated in Example 7.

Title: Improvements in television camera tubes
IPC: H01J31/32
Filed: 1953-03-23
Abstract: 725,348. Television pick-up tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 23, 1953 [March 26, 1952], No. 7911/53. Class 39 (1). A television camera tube comprises a photoelectric cathode 4, a target 6, a winding 15 for producing a magnetic field which is diverging as viewed from the photo-cathode, and a cylindrical accelerating electrode 8 extending over the greater part of the distance between the photo-cathode and the target, and terminating a short distance from the photo-cathode. Parallel to the emissive surface of the photo-cathode is an electrically conductive wall 14 through which the electrons pass. The wall 14 is located at a distance from the photocathode not greater than that of the accelerating electrode from the photo-cathode. The wall 14 serves to straighten the electric lines of force between the photo-cathode and the accelerating electrode.. It is stated that as compared with the method of image production by means of a diverging electric field in combination with the diverging magnetic field, spiral distortion is less troublesome, especially in the case of small magnifications. The wall 14 may be in the form of a foil which may be backed by a wide-meshed grid, or of a fine-meshed grid. It may be insulated from the accelerating electrode. The wall may then be given a higher potential than that of the accelerating electrode so as to prevent positive ions produced within the accelerating electrode from reaching the photo-cathode.

Title: Improvements in automatic dampers for vehicle suspension springs
IPC: B60G15/04
Filed: 1927-03-28
Abstract: 297,781. McNeil, W. March 28, 1927. Vibration-dampers of the kind in which an interrupted ring is in direct frictional engagement with a stationary drum and an operating-member is applied to the ring at one point only, the ring is formed as a tempered steel spring member, is made of the same general thickness from end to end and is sprung into engagement with the drum when assembling. In the construction shown in Figs. 1 and 3, the drum 20 is fixed to the vehicle frame 21 by a central bolt 24, set screw 22, and hub member 23 forming a bearing for a cover lever 26, 27, the outer end of which is connected by a rubber joint 29 to a link 30 leading to the axle or spring. One end of the spring shoe 36 is connected by a loose pin 35 to the heel of the cover lever 26, 27, this shoe being faced with frictional material. The pin 35 may engage a hole 37 at the other end of the shoe, to reverse the direction of resistance. The shoe may be formed with holes at several points round its periphery, the pin being engaged with any one of these points to vary the relation between the resistancs on the compression and the rebound. The drum or the spring shoe or both may be of spiral or elliptical instead of cylindrical shape to allow variation in the damping force according to displacement. In the modification shown in Fig. 5 the spring shoe 73 is arranged outside the fixed drum 60 and is oscillated by a pin 64 carried by the oscillating cover 65 connected to an operating lever 67. The rigid connecting link by which the arm is operated may be replaced by a flexible steel link or by a strap combined with a spring to keep the strap in tension. The strap may roll over a hump on the drum to vary the effective leverage. The length of the operating arm may be adjusted. Specification 259,776 is referred to.
