Title: Improvements in or relating to alkali and alkaline earth metal salts of pantothenic acid and methods of preparing same
IPC: C07C233/46
Filed: 1943-03-03
Abstract: Alkali and alkaline earth pantothenates are prepared by reacting an alkali or an alkaline earth salt of b -alanine with a  : g -dihydroxy-b  : b -dimethyl butyramide in a lower aliphatic alcoholic medium.  The reaction may be carried out at room temperature or any elevated temperature up to the boiling point of the solvent used.  In examples: (1) calcium b -alanate is reacted with d-a  : g -dihydroxy-b  : b -dimethyl butyramide at room temperature for four days in methanol solution to give pure crystalline d-calcium pantothenate.  (2) As in example (1) except that the reaction is carried out under reflux, the boiling being continued for two hours. Alcohols mentioned which may be used as solvents include methyl, ethyl, propyl, isopropyl, butyl and amyl.

IPC: H03K4/20
Filed: 1947-02-11
Abstract: 638,509. Sawtooth generating and integrating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 11, 1947, No. 3914. [Classes 40 (v) and 40 (vi)] In an integrating circuit arrangement, a first integrator feeds a second integrator, the outputs of the integrators being combined and fed to the input of the first integrator. In this manner a sawtooth wave is generated with the extremities of the sweep decreased in amplitude. Capacitor 8, discharged through valve 12 is charged over resistor 10, 11, the substantially sawtooth potential across the capacitor being fed to valve 13 having cathode and anode leads 15, 14. Valve 18 is arranged as an integrating circuit as described in Specification 580,527 so that the sawtooth component appearing across resistor 15 is applied over resistor 20 to give a further integrated component across capacitor 21 which is fed back over the coupling capacitor 24 to resistor 11. Since the apparent input impedance of valve 18 is low, capacitors 16, 19 are arranged to feed, in opposite phase, the differential of the sawtooth to the integrating valve 18. A sawtooth component thus appears across capacitor 21, the amplitude and sign depending on the setting of the tapping on resistor 14. Specification 598,304 also is referred to.

[Classes 79 (i) and 79 (ii).] A driving assembly for locomotives or tenders comprises a self-contained high-speed reciprocating steam engine unit geared to a driving axle or axles, combined with a gear casing and with axle-box guides, the assembly forming a cross stay between the side frames of the locomotive or tender. In the construction shown, there are two engines each driving an axle 1 or 2. Each engine comprises two horizontal cylinders 10, 11 and the crankshaft drives the axle through gearing 4, 5 enclosed in a casing 6. The engine and gearing form a unitary structure serving as a cross stay between the side frames 9 and provided with guides 7 for axle-boxes 8. The engine cylinders may be vertical or inclined. In a modification, an engine is mounted on the tender and drives one of the tender axles through a clutch or disconnectible gearing. In this construction a pinion on the engine shaft is in constant mesh with two idlers mounted on a carrier rotatable about the engine shaft. When the engine, which is reversible, is to drive the axle the carrier is rotated to bring one idler or the other, according to the direction of travel, into mesh with a gear wheel on the tender axle. The idlers rotate in the opposite direction to that of the engine shaft.

Abstract: 575,215. Sewing-machines. DEHN, F. B. (Lever Bias Machine Corporation). March 7, 1944, No. 4230. [Class 112] [Also in Groups VIII and XXVIII] Machines for special goods; feeding long lengths; folding- devices.-A method of making bias fabric comprises the step of pulling sheet material from supply through a series of zones during which it is formed into approximately tubular form, fastened at its adjacent edges to form a tube, subjected along the finished seam to regulated tension and to a regulated stretching and flattening pressure in order to roll it up or allow it to drop loosely folded into a container. Fabric is led in sheet form from a roll or container over rollers 11 to tube forming means 13, 17, adjustably carried by a stand 14. The overlapping edges, situated on the top of the tube, are then sewn or adhesively secured together by a machine 12 and the seam is pressed upwardly by a spring-urged plate 20, pivotably attached to the bed of the machine 12. Adjustable spring-urged fingers 22, pivoted to a rack bar 23, now press outwardly inside the tube to flatten it horizontally, the tube being fed by rollers 30, the top one of which applies the pull to the seam of the tube. The flattened tube is collected in loose folds in a container 32. This container is then placed upon a rotatable inclined table 63, moved by a hand wheel 72, so that the tube is fed spiral fashion about a mandrel comprising bars 43, the lowest one of which is carried by a weighted link 46, 47 so to apply opening pressure to the tube. The tube is then cut and the 'bias fabric collected on a roll 77 being fed thereto by rollers carried by a table 52 pivotably mounted on a support 51 so that the angle of bias may be varied.

Uncombed lap is advanced by feed roll 38 to the nip between a nipper knife 6 and a cushion plate 4 during both the forward swing of the nipper frame toward the detaching rollers 42, 44 and the return swing. The nipper knife 6 is supported by two arms 20, 22 which are pivotally connected to the nipper frame 2 which carries the cushion plate 4. Studs 26, 28 carried on the arms 20, 22 engage fixed cam tracks 30 and 31 so shaped to cause the knife 6 to move into the open position during the forward swing of the nipper frame 2 and the closed position during the return swing.

During the forward swing of the nipper frame the camming movement of the studs 26, 28 causes arms 20, 22 to pivot upwardly and open knife 6. This movement of arms 20, 22 causes links 50, 52 to pull arms 62, 64 on the clutch housings 50, 52 upwardly. This causes one clutch house (52) to rotate in the feed direction while the other clutch rotates in the slip direction; and vice versa during the return swing of the nipper frame during which closing of the knife 6 takes place.

Title: Bituminous emulsion
IPC: D21J1/16
Filed: 1945-02-20
Abstract: Bitumen in water emulsions are made from hard, brittle, bitumens which can be ground to a powder at 77 DEG F. without sticking to the grinding surfaces.  Asphalts and pitches, e.g., coal tar pitches de-oiled by steam distillation in vacuo, may be used.  The bitumen is preferably melted and emulsified in a colloid mill, which may be steam jacketed, under sufficient pressure to prevent boiling of the aqueous phase.  High melting non-sticky emulsifying agents are preferably employed, e.g., alkali soaps of resins such as "Vinsol" (Registered Trade Mark) though clay, protein, e.g., soya bean meal, defibrinized blood, or casein, soap or hot dilute caustic alkali may be used.  The emulsions on desiccation at 77 DEG F. yield a dry residue which readily re-emulsifies on stirring with water.  Examples describe the use of asphalt having a 190-200 DEG F. softening point and a penetration (A.S.T.M. D5-25 method) of 0-5.

Title: Improvements in or relating to refrigerator chambers
IPC: F25D11/02
Filed: 1949-02-17
Abstract: 657,376. Refrigerating ELECTROLUX, Ltd. Feb. 17, 1949, No. 4341. Convention date, March 2, 1948. [Class 29] In a refrigerator 11 containing a low temperature section 12 cooled by evaporators 13, 14, the chamber 11 being cooled by an evaporating-condensing system 22, heat is supplied only to the low temperature evaporators 13, 14 during de-frosting. The invention is described with reference to a continuous cycle absorption refrigerating system incorporating the evaporators 13, 14 supplied in parallel with liquid refrigerant by pipes 15, 16 respectively and in parallel with inert gas by a pipe 30 leading from the gas-heat exchanger 31, the gas flow being in the same direction as the liquid refrigerant. Unevaporated refrigerant and cold gases flow from the evaporators through a pipe 18 which is in heat exchange with the condenser part of the system 22. This heat exchanger is insulated as shown at 19. During defrosting, hot absorption solution or hot refrigerant is supplied to evaporators 13, 14 and to the pipe 18 where it stops condensation in the system 22. As the circulation in system 22 is thus stopped and as the exchanger 19 is insulated, no appreciable heat is supplied to the main chamber 11. The system 22 may also contain a non-condensing gas and may be formed from flat plates constituting inner walls of the chamber.
