Title: Improvements in hydraulic presses for compressing powdered charges
IPC: B30B11/02
Filed: 1936-06-04
Abstract: 476,245. Compressing explosive charges. DEUTSCHE WAFFENUND MUNITIONSFABRIKEN AKT.-GES. June 4, 1936, No. 15689. Convention date, June 5, 1935. [Class 9 (i)] Relates to multiple-action presses for pressing powdered charges such as the priming and tracing charges of projectiles. According to the invention, a uniform pressure is imparted to the several press plungers by means of one or more bellows chambers which are under the action of adjustable hydraulic or pneumatic pressure. In the construction shown, the press comprises two bellows chambers 7, 36, which are filled with liquid and which are connected with each other by a supply conduit. Both bellows are firmly attached to a member 35 extending between the pillars 41 of the press. The upper bellows 36 carries the charges 10 and the lower bellows 7 is adapted to be compressed by means of two cams 5, 6 on a shaft 4. This shaft also carries two end cams 31 engaging with bell-crank levers 32 which' are adapted to impart a vertical reciprocating motion to a pair of bolts 34. The upper ends of the bolts are connected by two cross-bars 38, 39, carrying the press plungers 11. In operation, the plungers are first lowered by the cams 31 to press lightly upon the charges 10, and the pressing is then completed by the bellows under the control of the cams 5, 6. To regulate the pressure exerted by the bellows, a conduit 12 leading therefrom is connected to a third bellows 13, the free end of which carries a roller 15 engaging with a worm 16 on a shaft 16a. An end disc 17 on this shaft is connected by a steel band 18 to one arm of a bell-crank lever 19, the other arm of which carries a movable weight 20. The tendency of the bellows 13 to rotate the shaft 16a is thus resisted by the weight 20, which can be adjusted to control the pressure of the hydraulic system. The cross-bars 38, 39 are adjustably mounted upon the bolts 34, being connected directly to bushes 30 which are threaded on the bolts and which are rotated, for adjustment purposes, by gearing 28, 29, actuated by a hand wheel 43. The press plungers are arranged upon a system of levers and coact with springs 42 in such manner that the same predetermined pressure is applied to the charges even if one or more of the charges be missing. Visible or audible signalling devices may be provided to indicate the absence of any of the charges.

Title: Improvements in or relating to the production of carbamates of the alkali metals and alkaline earth metals
IPC: C01B21/12
Filed: 1933-06-01
Abstract: Carbamates of alkali and alkaline earth metals are obtained by bringing together a soluble salt of the metal and carbon dioxide in the presence of water, ammonia and a diluent liquid miscible with water but in which the carbamate to be produced is less soluble than in water, the diluent liquid being present is proportions of about 100 to 200 per cent by weight with respect to the water and the reaction temperature being above about 20 DEG  C. The diluent liquids referred to are ethyl alcohol, methyl alcohol and acetone.  Sodium carbamate may be obtained from sodium chloride, bromide, iodine, or nitrate and potassium, lithium, calcium, barium and magnesium carbamates may be obtained from the chlorides, bromides, iodides or nitrates of these metals.  The metal salt may be dissolved in an aqueous alcohol solution, followed by addition of ammonia and carbonation, or the metal salt may be dissolved in an aqueous alcohol solution, the ammonia and carbon dioxide being then added together, or the metal salt may be dissolved in water, ammonia and carbon dioxide being added to this solution and the alcohol being then added to the resulting solution.  It is preferable to employ a slight excess of both ammonia and carbon dioxide and to have a ratio of ammonia to carbon dioxide of at least 2 : 1.  According to an example, sodium chloride is stirred into a mixture of ammonia, carbon dioxide, water and ethyl alcohol, the temperature being about 30 DEG C.  The separated sodium carbamate may be freed from any ammonium carbamate by volatilization in a current of dry air.  Ammonium chloride may be recovered by evaporating the reaction medium.  The Specification as open to inspection under Sect. 91 comprises also the production of the carbamates by bringing together water, ammonia, carbon dioxide and a soluble salt of the metal in the absence of any diluent liquid of the kind above referred to and is not restricted in the above described manner as to proportions of diluent liquid or to the temperature employed.  This subject-matter does not appear in the Specification as accepted.

Abstract: 650,778. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 18, 1947, No. 16144. [Class 40 (vii)] In a navigation aiding device employing a direction-finder to enable a craft to home on to a radio beacon, a straight course is maintained in the presence of a drift force by a compass unit, any displacement of which from the current course setting is caused to operate through a telemeter system and reorient the direction-finder directional aerial so that the navigator in reheading the craft to realign the aerial with the beacon corrects for drift and maintains a straight course. As shown, a three-wire telemeter system comprising resistance elements L8 and P7 is associated with the loop L of a direction finder unit C providing " homing" " facilities and a repeater P18 of a master compass. One pair of contacts L6, L7 are positioned by the loop and a second pair carried by rotatable slip rings P10, P11 are positioned by the compass repeater. After correctly heading the craft at the beacon, the contacts P8, P9 are first aligned with tapping point P6 so as to balance the telemeter system and then a clutch P17 operated to engage the compass repeater P18 with the slip rings. Thereafter any change in the compass setting reacts in a displacement of contacts P8, P9 and causes a potential to appear on leads W4, W5. This potential is applied to unit C through a periodic make-andbreak switch D, and at the next make actuates a motor L3, L4, L5 to cause the loop, together with contacts L6, L7 to be rotated until balance of the telemeter system is re-established. For the purposes of steering an indicator P is provided, the coils P1, P2, P3 being connected via switch SW1 in the lower position to the " homing " output of unit C. The craft is headed to maintain the needle at 0 degrees on a fixed bearing scale P14. Normal radiocompass facilities are also provided by unit C and are obtained by placing switch SW1 in the upper position. Hence, the loop is automatically maintained aligned on a beacon with the bearing repeated to the indicator P, the pointer indicating relative bearing on scale P14 and true bearing on a rotatable scale P15 controlled from a compass repeater P16. Specification 550,619 is referred to.
