Title: Apparatus for generating voltages of harmonic frequencies from an alternating current supply
IPC: H03B19/00
Filed: 1937-08-10
Abstract: 502,086. Generating high - frequency oscillations. STANDARD TELEPHONES & CABLES, Ltd. Aug. 10, 1937, No. 22009. Convention date, Oct. 17, 1936. [Class 40 (v)] [Also in Group XXXV] An arrangement for producing a number of odd harmonics of uniform amplitude from a source of A.C. S, Fig. 4, comprises a rectifier bridge K1-K4 supplied across the diagonal AB from the source S through a resonant harmonic frequency rejector circuit L1 C1 and having connected cross the other diagonal a source of polarizing potential, the output circuit including a condenser C2 and a resistive load R2. In a modification the positions in the circuit of the rectifier bridge and the harmonic frequency rejector circuit, may be reversed. If desired inductance L2 may be included in the output circuit. The source of polarizing potential may comprise a condenser CO having a resistance RO in parallel therewith. The resistive load may comprise a number of series or parallel connected filters for separating the harmonic frequencies. In a modification the rectifiers K3, K4 are replaced by condensers and the condenser CO omitted. In a further modification shown in Fig. 10 even harmonics are also produced by means of a rectifier bridge P, the harmonics being obtained from the output resistance R3 of the bridge. In this arrangement separator valves VI, V2 are employed to avoid the injurious effects of parasitic capacities in shunt to R2 and R3. Specification 477,875, [Group XXXV], is referred to. The Specification as open to inspection under Sect. 91 comprised also the subject-matter of Fig. 13 (Cancelled). In this arrangement the rectifier bridge is replaced by a full-wave rectifier D1, D2 having a source of biassing potential connected in its D.C. circuit. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to refrigerating systems
IPC: F25B41/06
Filed: 1947-08-08
Abstract: 649,099. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 8, 1947, No. 22048. Convention date, Aug. 10, 1946. [Class 29] In a compression or other refrigerating system wherein liquefied refrigerant flows through a capillary tube 10 and a valve to the evaporator by a connection 12, the valve maintaining a sufficient pressure in the tube 10 to prevent formation of ice therein, the valve comprises a valve member 19 co-operating with a flexible diaphragm 17 clamped between two parts 15, 16 of the housing, the part 16 being made, e.g. of steel, and the part 15 of material of lower thermal conductivity, e.g. stainless steel to prevent cooling of the capillary tube from the cold side of the valve. The valve member 19 is urged by a spring 20, Fig. 2, or by a resilient member 24 clamped in the housing and separated from the diaphragm 17 by a spacer 25, Fig. 3. If ice should clog the valve, the resulting higher pressure in the high-pressure part of the housing flexes the diaphragm to free the ice. The Specification as open to inspection under Sect. 91 comprises also a weighted valve member 36 having a part 38 guided in a bore 37 in the housing, Fig. 5 (Cancelled). Alternatively the weighted member may act on an orifice in a flexible diaphragm. This subject-matter does not appear in the Specification as accepted.

Patent GB-715183-A (GB)
Title: Pyridoxamin derivatives and process for the manufacture thereof
IPC: C07F9/58
Filed: 1952-09-12
Abstract: A process for the manufacture of pyridoxamin derivatives comprises reacting pyridoxamin or a salt thereof with metaphosphoric acid, hydrolysing the product and, if desired, converting the pyridoxamin-51-monophosphoric acid ester so formed into its magnesium or alkaline earth metal salts.  The metaphosphoric acid is produced by slowly heating orthophosphoric acid until water ceases to distil off and the liquid becomes turbid.  The initial reaction product contains pyridoxamin-51-triphosphoric acid, probably together with higher and lower phosphoric acid esters.  Hydrolysis may be effected by heating the initial product with water or acid. Examples describe the preparation of the monophosphate by the above method.  It is converted to its magnesium salt by reaction with magnesium hydroxide at pH 6 to 7 and filtered off; a further quantity of the salt is recovered by treating the mother liquor at pH 8-9 with more magnesium hydroxide.  The calcium salt is obtained by reacting the magnesium salt with calcium acetate or by reacting the monophosphate with calcium hydroxide.
