Filed: 1935-09-23
Abstract: 453,027. Heating buildings. VENNET, G. VAN DER, 4, Rue de Chestret, Liege, Belgium. Sept. 23, 1935, No. 26349. Convention date, Sept. 27, 1934. [Class 64 (ii)] [See also Group XXIX] An apparatus for maintaining the pressure in a system heated by hot water comprises a vessel 2 containing mercury 4 connected at 2a to the return pipe of the hot water system. A tube 5 closed at the top dips into the mercury, and a tube 6 opening at the top into an expansion vessel 3 also dips into the mercury less deeply than the tube 5 and is flared at the lower end. Expansion of water in the system forces mercury up the tube 6 till the lower end is uncovered, when water rises through the mercury in the tube 6 into the vessel 3 and returns to the vessel 2 through a valve 7. According to the Specification as open to inspection under Section 91, the tube 5 may open at the top into the vessel 3 and the tube containing the valve 7 is omitted. This subject-matter does not appear in the Specification as accepted.

Patent GB-503196-A (GB)
Title: Improvements in magazine gramophones
IPC: G11B17/10
Filed: 1937-09-29
Abstract: 503,196. Magazine gramophones. MANN, G. S. Sept. 29, 1937, No. 26382. [Class 40 (ii)] In a magazine gramophone of the kind in which records are transferred in turn from a storage platform to the turntable, and the platform is raised step by step as each top record is removed therefrom, the upward movement of the platform is controlled by a member whose movement is dependent on the flow of a fluid, and a valve adapted for operation by the top record on the platform is provided for controlling the flow of the fluid. The invention is shown applied to a gramophone such as that described in Specification 472,135, in which the records are transferred to a depressible turntable 5. The turntable is carried by a sleeve 14 which is rotatable on a fixed guide rod 15 by means of a motor 16, and which is coupled by a lever 17 to a sleeve 7 on which the platform 6 for unplayed records 11 is mounted. The sleeve 7, formed in two adjustably connected parts, is guided in a bearing 9, and is pressed upwardly by a spring 12. The arm of the lever 17 which is adjacent to the turntable sleeve is connected by a link 19 to the rod 20 of a piston 21 working in a cylinder 22 filled with oil or the like. The upper and lower ends of the cylinder are connected by a conduit 23 which leads through a valve box 24, the arrangement being such that the valve 25 is normally closed by a spring 26, so that the piston 21, and consequently the parts 5, 6 cannot move. A pivoted control arm 27 is so mounted that its weighted free end rests on the top record on the platform 6. When this record is removed for transfer to the turntable, the arm 27 falls, and through a rod 30, opens the valve 25. Flow of the fluid from one end of the cylinder 22 to the other is thus permitted, so that the turntable 5 falls and the platform 6 rises. As soon as the record then at the top of the pile 11 reaches its proper position, the arm 27 is lifted sufficiently to allow the valve 25 to close again, and further vertical movement of the platform and turntable is stopped. A valve 31 in the piston 21 allows the movement to' be reversed, for reloading the platform. Specifications 402,779 and 503,195 also are referred to.

Title: Bis[ª-(ortho-hydrocarbonoxyphenyl)isopropyl]amines
Inventor: HEINZELMANN RICHARD VOORHEES
Filed: 1952-10-24
Abstract: The invention comprises bis[b -(ortho-hydrocarbonoxyphenyl)isopropyl]-amines <FORM:0722301/IV (b)/1> wherein R is a hydrocarbon radical having from one to seven carbon atoms inclusive, and salts thereof, and their preparation by reducing, with hydrogen under pressure and a hydrogenation catalyst, e.g. Raney nickel, platinum oxide, palladium or copper chromite, a solution of an ortho-hydrocarbonoxyphenyl acetone and ammonia or an ortho-hydrocarbonoxyphenyl-isopropylamine.  The reaction may be effected in a solvent such as an ester, alcohol or hydrocarbon. Mixtures of diastereoisomeric amines thus obtained may be separated by the fractional crystallization of their salts or by forming a complex with an alcohol, e.g. methanol, ethanol, propanol, ethylene glycol, propylene glycol, cyclohexanol and diethylene glycol monoethyl ether, and separating the so-formed complexes by their different solubilities in excess of alcohol. Examples disclose the production of compounds in which R represents methyl, benzyl, isopropyl, n-propyl and in addition n-hexyl.  Compounds are also mentioned in which R represents ethyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-amyl, isoamyl, sec-amyl, 2-methylbutyl, 1-methylpentyl, 2-methylpentyl, cyclopentyl, cyclohexyl and phenyl. o-Hydrocarbonoxyphenylacetones are obtained by reacting o-hydrocarbonoxybenzaldehydes and nitroethane in the presence of a basic condensation catalyst.  o-Hydrocarbonoxybenzaldehydes are obtained by condensing in the presence of sodium ethoxide, salicylaldehyde with a hydrocarbon halide, e.g. benzyl chloride, isopropyl iodide, n-propyl iodide and n-hexyl bromide.
