Title: Apparatus for conditioning gaseous fluids
IPC: B64D13/06
Filed: 1953-07-20
Abstract: 729,626. Ventilation. GARRETT CORPORATION. July 20,1953 [Aug. 1, 1952], No. 20039/53. Class 137. [Also in Group XIII] Apparatus for cooling a gas, e.g. air, supplied to a flying suit 33 or other enclosure, comprises a conduit 24, an indirect-contact heat exchanger 12, a duct 28, a second cooler (e.g. an expansion turbine 29), and an outlet passage 31 leading to the enclosure, all connected in series, a branch passage 47 connecting the outlet of the second cooler to the heat exchanger 12, and a by-pass 35 connecting the duct 28 to the outlet passage 31 downstream of the branch passage 47; the flow of air through the branch passage 47 is controlled by means responsive to one of the characteristics of the gas in the apparatus. In the form shown, a valve 50 is actuated by a motor 51 controlled by a regulator 78 described in Specification 687,154, [Group XXXV]. The regulator 78 is controlled by the rate of change of temperatures influencing thermistors 80a and 80b, and by the temperature influencing a thermistor 81a or 81b, so that the temperature of the air supplied to the suit 33 is maintained at a required level. In the heat-exchanger 12, air from the branch passage 47 cools the air from the conduit 24. The turbine 29 drives a fan 16 which impels coolant air through another heat exchanger 10, in which compressed air from a conduit 19 is cooled before entering the conduit 24. A valve 37 in the by-pass 35 is closed or opened (by a motor 36 controlled by a pressure-actuated switch 56) according to whether the pressure of the air entering the heat exchanger 10, or the difference between that pressure and ambient pressure or cabin pressure, is above or below a certain level, so that either none or all of the air supplied to the suit 33 passes through the by-pass 35. A valve 39 in the duct 28 is controlled by the difference between the pressure of the air leaving the turbine 29 and ambient pressure. A non- return valve 45 is provided in the passage 31 upstream of the junction of the by-pass 35. Automatic pressure-control and pressure-relief valves 99 and 102, and manually operable bleed and pressure-control valves 101 and 103 are provided. Specifications 620,538, [Group XXVI], 654,622 and 681,144 also are referred to.

Abstract: 1,174,492. Electrolytic capacitors. P. R. MALLORY & CO. Inc. 2 May, 1967 [2 May, 1966], No. 20260/67. Heading H1M. Anodes for electrolytic capacitors are manufactured by placing a foil 12 of film-forming metal against a backing plate 13, clamping a template 10 to the foil 12 and backing plate 13, spreading a slurry of a powder of the filmforming metal in a liquid carrier, or possibly the dry powder which is subsequently moistened, over the template to fill or partly fill holes 11 and contact foil 12, removing the excess, e.g. by a squeegee, fusing the deposits of powder to the foil 12 by sintering before or after removing the template. The capacitor is completed by anodizing the foil and sintered deposits, applying a semi -conductor coating over the anodized deposits, applying counter-electrodes over the semi-conductive coating, attaching cathode leads to the counter electrodes and anode leads to the foil away from the semiconductive coating and counter electrodes and separating individual capacitors from the processed foil. These may be encapsulated with, e.g. epoxy resin. The template may be of polytetrafluoroethylene if to be removed prior to sintering, or of molybdenum or boron nitride otherwise.
Patent GB-148347-A (GB)
Title: An improved appliance to be used in the making of boxes, cases, crates and the like
IPC: B27M3/34
Filed: 1920-07-09
Abstract: 148,347. Case Making Machine Co., (Assignees of Tregaskis, E. F.). April 29, 1916, [Convention date]. Machines and apparatus for making boxes &c. Relates to an appliance for holding the end and division pieces of a box, crate &c. during the nailing-on of the sides, comprising means for permitting the rotation of the parts as the construction progresses. A table A carries in brackets B at each end a rocking shaft D; rigidly secured to sleeves D<1> at each end of the shaft are two arms E, the rear ends of which are connected by a telescopic rod E<2>. A second pair of arms F, pivoted at F<2> to the sleeves are connected and urged together at their rear ends by a spring H. Both sets of arms carry at their forward ends revoluble grippers E', F<1> respectively. Arranged longitudinally of the table is a stop-piece C adjustably supported on angle plates. The box ends are held between the grippers E<1>, F<1>, and the division pieces, if any, are supported in grippers or clips T<2> carried by a double lever T hinged at T' to one of the table cross-pieces A'. After nailing on the battens of one side, the box is lifted by depressing a treadle, which causes a rope to pull on the rod E<2>, so raising the front ends of the arms E, F, and at the same time pulling down the lever T and disengaging the clips T<2> from the partitions. To enable the partly-completed box to be rotated mechanically, the spindle E'' of the gripper E<1> at the top of Fig. 1 carries a one-way clutch and a pinion S<1> meshing with a toothed wheel S<2> on a spindle S<3> secured to the arm E; the spindle S<3> also carries a toothed or ratchet wheel S<4> gearing with a toothed rack S<5> secured to the table. By reason of this arrangement, when the arm E is raised, as described above, the gripper E<1> is caused to rotate through a quarter turn, bringing the box into position for the nailing of the next side. Owing to the clutch, the descent of the arm E causes no movement of the grippers. To enable the grippers F<1> to be opened, a lever J mounted on the shaft D is caused to operate a T-shaped bell-crank L, the legs L<1>, L<2> of which are connected by rods M<1>, M<2> to the arms F so that the rear ends of the latter can be forced apart against the action of the spring H. A slight side movement of the lower gripper E<1>, Fig. 1, each time the grippers F<1> are opened by the lever J to release the finished box, is provided for. The arm E carries a cam N, which is formed with inclined recesses N<1>, see Fig: 5, where the parts are shown separated, and carries centrally the spindle E<4> of the gripper. Between the two is a recessed plate 0 carrying a series of balls O<1> and connected by a rod M<3> to the third arm L<3> of the bell crank L. The parts E' N, and the recessed plate are kept pressed together by a spring E<5>, Fig. 1, on the projecting end of the spindle, and each movement of the plate by the rod M<3> causes a small outward movement of the gripper E<1>.

Patent GB-369118-A (GB)
Title: Process for concentrating aqueous formic acid
Filed: 1931-07-20
Abstract: Aqueous formic acid is concentrated by distilling with an organic base of high boiling point which suffers no deleterious alteration when heated with formic acid and which forms neutral or acid formates which do not decompose during the distillation of the water but which liberate the acid at higher temperature or lower pressure.  Suitable bases are quinoline, quinaldine, picoline, dimethylaniline, diethylaniline, and benzimidazole.  A quantity of the base or of a mono-formate of such base may be added in the fractionating column, preferably on the countercurrent principle sufficient to combine with such free acid as is passing through the column.  Preferably an excess of base is avoided.  In examples, aqueous formic acid is distilled with quinoline, quinaldine and benzimidazole respectively, the water being distilled at ordinary pressure, after which the pressure is reduced to break up the formate of the organic base.
