Title: Improvements in electric resistance heaters for agricultural and other purposes
IPC: A01G13/06
Filed: 1934-03-23
Abstract: 435,055. Wire resistances. DAVIS, N. R., 43, Eyre Court, Finchley Road, London. March 23, 1934, No. 9218. Drawings to Specification. [Class 37] In a soil-heating cable a thermostatic switch controlling the heating current is enclosed actually within the lead sheath of the cable or within a continuation thereof, this switch being arranged to be substantially unaffected by the temperature of the heating resistances. The controlling effect of the switch therefore approximates closely to the variation of the surrounding soil temperature. The switch may be placed in a bulged portion of the lead sheath or in a metal tube sealed to the sheath to form a continuation thereof. The copper leads of the thermostat are made sufficiently thin to prevent undue conduction of heat to the switch and it is stated that very little heat conduction takes place along the lead sheath.

Abstract: 530,968. Stretching tubular fabrics. SAMCOE HOLDING CORPORATION. March 24, 1939, No. 9253. Convention date, April 5, 1938. [Class 42 (i)] In apparatus for stretching and finishing tubular fabrics or fabrics sewn into tubular form, the flat stretcher frame has travelling bands 31 at its edges which are driven by external rollers 24. The bands 31 may be of leather, fabric, chain, or spiral spring and may be in front of or behind or both in front of and behind the drive rollers 24. The bands may extend along the non-parallel parts 45 of the spreader, or a single band may serve both sides of the spreader as shown in Fig. 11. The drive rollers 24 may be plain cylindrical rollers as shown in Fig. 11 in which case rollers 50 for supporting the frame are provided, or grooved as shown in Fig. 3. In this case the rollers 33 carrying the band 31 are driven by the parts 36 of the roller 24, the bands travelling faster than the fabric, but the speeds of the fabric and bands may be equal or in any other ratio, so that if desired the fabric may be shrunk longitudinally before it enters the calendering &c. rolls 21. The Specification as open to inspection under Sect. 91 shows a drying chamber fitted with several superposed travelling spreaders connected by curved guide frames. This subjectmatter does not appear in the Specification as accepted.

Abstract: 590,134. Tanks. GRUENAIS, A. April 13, 1945, No. 9295. Convention date, Nov. 4, 1943. [Class 69 (i)] A storage tank comprises a body of revolution e, the cap and/or bottom of which are provided with corrugations concentric about the axis AA of the body e. The convex portions a of the corrugations may have a larger radius of curvature than the concave portions b. Stays c located on the axes of the concave portions b connect the top and bottom, whilst the concave portions may be reinforced by angle irons or by a filling of concrete. All the corrugations at the same level are connected together by means of pipes f, g. In order to withstand the dead weight of the structure, the bottom is reinforced by stiffeners at the periphery. In one form of tank, the centre of the bottom is flat, the outer periphery being formed by a single corrugation. The concave portions b may be replaced by plane surfaces and the upper corrugations may be filled with water for cooling purposes.

Patent GB-573468-A (GB)
Title: Improvements in or relating to the manufacture of acetic anhydride
Filed: 1941-07-23
Abstract: Acetic anhydride is produced by oxidation with molecular oxygen of a mixture of acetaldehyde and paraldehyde at below 60 DEG  C. followed by distillation in which the water is entrained by the paraldehyde. The initial mixture may be obtained by partial polymerization of acetaldehyde or partial depolymerization of paraldehyde.  Suitable depolymerizing agents are sulphuric, phosphoric and sulphonic acids and acidic salts such as zinc, aluminium and ferric chlorides and vanadic acid.  The oxidation catalyst should be of such nature and quantity as not to neutralize the depolymerization agent; for instance, manganese or cobalt acetate should be used in small quantity; vanadic acid, especially when activated with acetic acid, may be used with or without cobalt or manganese acetates.  An active vanadic catalyst may be made by adding hydrogen peroxide or another peroxidic compound to vanadium pentoxide in acetic acid, whereby the pentoxide is dissolved.  Suitable apparatus is described. Examples describe the oxidation with oxygen of (1) paraldehyde, acetaldehyde, and vanadic acid; (2) paraldehyde, sulphuric acid and vanadic acid; (3) paraldehyde, acetic acid, sulphuric acid, cobalt acetate and copper acetate.  In each case the water is removed with paraldehyde by azeotropic distillation.  The concentration of percompounds in the reaction product can be reduced by diluting with paraldehyde or by adding manganese acetate, preferably after neutralizing any acid depolymerizing agent present.  Specification 461,808 is referred to.

UNITEDCARR FASTENER CORPORATION, 31, Ames Street, Cambridge, Massachusetts, U.S.A.-(Assignees of Jones, W. 1.; 57, Richfield Road, Arlington, Massachusetts, U.S.A.) March 26, 1935, No. 9410. Convention date, April 21, 1934. [Class 89 (i)] A nut is formed from sheet metal and comprises a base 1, an aperture 2 around which extends a tubular portion 6, and shank-engaging portions 3 extending away from the base and ending in parts 4 curved to engage a screw &c. The parts 3 are first stamped out as shown in Fig. 5, the plate is then placed between dies which bend the parts 3 out of the plane of the base and form corrugations 7 and move the parts 3 to project over the projection 6. The nut is engaged with the threaded shank of a screw &c., by a straight thrust, and is locked by a slight amount of rotation of the screw &c. In a modification, the base is arched in the direction of the ends 4 to produce a greater gripping of the thread. In a further modification, the ends 4 are inclined to coincide with the angle of the thread. A modification is described wherein a sheet-metal cap is crimped over the edge of a nut with a circular base. The edge of the cap, or projections 8 on the base, raises the body from the engaging plate. The plate is bent in tightening the nut, and the gripping power thereby increased.

Electromagnetic interrupters; mercury switches of the type comprising an iron plunger floating in a column of mercury sur-. rounded by a coil and connected in a circuit to act as a current limiter, condensers being connected across the contact points as described in the parent Specification, are provided with means which automatically maintain the circuit broken when a predetermined excess supply is called for, until the container is tapped to release the core again. In the form shown in Fig. 1, a flange on the lower end of the plunger at a certain excess current engages an annular groove e below the surface of the mercury; the groove may be located above the mercury and be engaged by a flange on the upper end of the plunger. Instead of the groove a catch on the plunger or in the tube may engage a recess in the tube or a flange on the plunger. Alternatively, the top tap of the container may be formed as a magnet or electromagnet to engage and hold the core when sufficiently raised by the excess current. In a modified construction, shown in Fig. 3, the core b is tubular and, at a certain height, engages and is retained by a conical projection e depending from the cap and made of hard rubber.
