Title: Improvements in or relating to vacuum-jacketed flasks
IPC: A47J41/00
Filed: 1939-05-08
Abstract: 528,490. Vacuum flasks and closures therefor. SCHIERENBECK, F. A., and ALBONS, A. E. May 8, 1939, No. 13759. [Classes 125 (i) and 125 (iii)] An anti-drip device for a vacuum-jacketed flask comprises a tube having a cup-shaped outer extremity fixed within the neck of the flask by means of pack ing located between the tube and the neck, the device being adjusted in position in the neck by pressure exerted on the packing by means of a member adjustable longitudinally of the tube; the tube may be closed by a stopper. As shown the tube 1 is in two parts screwed, together and the packing ring 4 is compressed between an outer shoulder 3 on the tube by the collar 6 screwed on the outside of the tube and adjustable longitudinally thereof. The cup-shaped entrance 7 on the tube concentrically, surrounds the stopper 9 which screws into the tube and seats against the inner stop flange 10 ; in a modification the tube is a single part and the packing ring is kept in position on the tube by engaging ridges, edges or the like on the exterior thereof. In a further form, the cup-shaped extension is separate from the single-port tube, screws upon the exterior thereof and engages a loose collar which compresses the packing ring.

Title: Methods and apparatus for electrochemical machining of metals
Inventor: HUGHES HERBERT DENIS
IPC: B23H3/00
Filed: 1963-04-08
Abstract: <PICT:1046471/C6-C7/1> A method for electro-chemical machining of a number of workpieces one at a time and each to the same predetermined dimension comprises gauging each workpiece to determine the actual initial dimension of a part to be machined and controlling the quantity of current utilized for the electro-chemical machining in accordance with the gauging result for the purpose of terminating the machining when the workpiece has been reduced to the predetermined dimension.  Thus, massproduced rod-like workpieces of the same nominal diameter may each be electrochemically machined accurately to a predetermined diameter.  Machining is by an electrode 10 which machines a zone 9 of a rod workpiece 4 as it is rotated by a lathe 5, 6, 7, electrolyte being supplied from a tank 12. Under these conditions the rate of metal removal is directly dependent on current flow.  Circuitry in an analogue computer is pre-set according to the predetermined required diameter.  The actual diameter of a rod is gauged at a gauging position 21, 23 by a transducer device.  A capacitor C, (Fig. 2, not shown) in the computer circuit is charged in accordance with the gauged valve.  The rod is then removed from the gauging position to the electrochemical machining position.  The machining current produces a voltage across a shunt 26 (Fig. 2, not shown) and this voltage provides a signal which progressively reduces the charge of the capacitor C1.  As soon as the capacitor voltage falls to zero, which has been preset to occur when the rod is of the predetermined required diameter, a relay operates to switch off the electrolyzing current.

Title: Resolution of racemic ª -í¸-dihydrodesoxycodeine methyl ether
Filed: 1953-02-17
Abstract: The invention comprises salts of optically active dibenzoyltartaric acids with optically active forms of b -D 6-dihydrodesoxycodeine methyl ether, and a process for resolving the racemate of the said ether by reacting it with an optically active dibenzoyltartaric acid and separating the salts so obtained by making use of their different solubilities.  In an example, the racemic ether and the L(+)-acid are reacted in methanol to precipitate the salt of the d-ether, from which the base is liberated by the action of ammonia and may be characterized by conversion to its picrate and methiodide.  The salt of the D(-)-acid with the l-ether may be similarly prepared, preferably from the base recovered from the filtrate from the foregoing operation.

In the steam generator shown and described in the parent Specification the upper part of the firebox in which the tertiary air supply tuyÞres s, t, u, are located is divided from the radiation space of the generator by a partition formed with an opening for the discharge of the combustion gases to the radiation space. As shown in Fig. 1 the partition V comprises a wall of tubes, a cylindrical sleeve Z depending from an opening therein, whilst in Fig. 3 the upper part of the firebox is of cylindrical formation and the sleeve W is a diffuser-like enlargement of the sleeve Z. The tertiary air tuyÞres s, t, u, and the partial boxing- in of the upper part of the firebox produces in this part of the firebox a cyclonic effect so that under certain conditions a fume filter and a conduit for returning the fume-borne ash particles separated therein to the firebox may be omitted. As shown in Fig. 5 downwardly inclined ash-deflecting surfaces y are provided above the tuyÞres s, t, u, such surfaces being disposed around the whole periphery of the firebox and progressively increasing in width so that the tuyÞres s are covered by the narrowest deflecting surface whilst the tuyÞres u are covered by the widest deflecting surface. Each surface may be formed of tubes helically wound in the same direction as the air is whirled by the tuyeres s, t, u.

Title: Improvements in or relating to vibration recorders
Filed: 1929-05-14
Abstract: 328,816. Deuta-Werke vorm. Deutsche Tachometerwerke Ges. Nov. 8, 1928, [Convention date]. Rest or motion recorders.-In a rest or motion device for detecting the operation of moving bodies such as a vehicle a member, directly mounted on the central shaft of the clockwork, is provided and is adapted at each revolution of the shaft to shift the marking member for the purpose of making records on succeeding circles on the record-disc. As shown in Figs. 1 and 2, a base 3 secured to the body under observation has hinged thereto a cover 1 in which all the working parts are assembled. The clockwork has a dial visible through an aperture 37 and has a rearwardly extending spindle 4 carrying a disc 6 on which is guided a slide 7 with a pawl 8 engaging ratchet teeth on the disc 6. A spring controlled lever 13 with a shoulder 14 and tooth 15 co-operates with the pawl 8 and with the teeth of a spring controlled segment 17 pivotally mounted on an axis 11. The segment 17 has a slot 19 in which works the pin 20 of an arm 21 on a hub 23 rotatably mounted on a bush 27 on an axis 12. To the hub 23 is secured an arm 22 carrying a blade spring 24 which is provided at its end with a marking member 26 arranged over a supporting plate 25. On the bush 27 is pivoted a vibration member 28 the weight of which is supported by a coil spring 29. The member 28 is maintained in frictional contact with the arm 21 by means of a spring 30 so as to transmit its oscillations to the marker 26, the pin 20 being allowed limited play across the slot 19. The record-disc which passes over the support 25 is clamped in position on the spindle 4 between a squared head 32 and spring 33. After each revolution of the record-disc the pawl 8 causes an escapement action of the lever 13 to allow the segment 17 to rock to the extent of one tooth displacing the marker radially and producing a record as shown in Fig. 5. The winding of the clock-spring is effected by rotation in a direction opposite to that of the arrow shown in Fig. 1, the pawl 8 riding over the teeth of the disc 6 when the slide 7 strikes the shoulder 14. When the casing is opened and the arm 22 adjusted by hand to its initial outward position the spring 24 is raised by one of the legs 35 of a spring- controlled U-shaped member to be free of the record-disc. On the closure of the casing after replacing the record-disc the other leg is depressed by the base 3 to permit the marker to engage the record-disc.

Title: Process for the preparation of coatings based on unsaturated polyester resins and monomeric vinyl compounds
IPC: C08K5/09
Filed: 1963-04-17
Abstract: A coating composition comprises an unsaturated polyester resin, a monomeric unsaturated compound having a terminal =CH2 group, a peroxidic catalyst, an accelerator which is a cobalt compound and one or more hydroxycarboxylic acids.  0.7 to 7.0 mg. of hydroxycarboxylic acid are added per 1 m.g. of cobalt (calculated as metal). Hydroxycarboxylic acids mentioned are tartronic, malic, tartaric, citric and lactic, and they are preferably added in solution, e.g. ethanol, to the unsaturated polyester-monomer mixture, but they can also be added to the molten unsaturated polyester before it is dissolved in the monomer. In the examples the unsaturated polyesters are formed from (a) maleic and phthalic anhydrides and propane-1,2-diol and (b) fumaric acid, phthalic anhydride, ethanediol, propane-1,2-diol, and pentaerythritol triallyl ether, and the comonomer is styrene.
