Title: Improvements in or relating to surgical pads
IPC: A61F13/06
Filed: 1960-01-26
Abstract: 867,272. Corn pads. SCHOLL MFG. CO. Ltd. Jan. 26, 1960 [May 25, 1959], No. 2857/60. Class 81 (2). A corn pad comprises a unitary layer of cushioning material coated on one side with adhesive and shaped to define a head portion 3 from which a narrower strip 4 extends, generally disposed portion 9, 10, 11 of the scrip extending from the free end so that they may be selectively trimmed or rolled on to the adhesive coating of an adjacent portion to increase the thickness of the free end of the strip leaving the adhesive on the remainder of the strip exposed. A pad for a hammer-toe corn comprises a layer <SP>1</SP>/ 16 -<SP>1</SP>/ 8  inch thick of cushioning material, e.g. moleskin, felt or pile fabric or foam material, which is spread with adhesive on one side and is shaped to define an apertured portion 3 extended by a narrower strip portion 4. Sections 9, 10, 11 of the strip portion may be folded under a rolled up from the free end to form a pad of two or more layers which in use is placed against the toe to the rear of the corn which is surrounded by the apertured portion. The strip may have indicia 8, e.g. notches, to indicate where it should be folded. The pads are sold mounted on a temporary backing either flat or with the folded or rolled portion already formed. In use, two or more such pads may be superimposed to give a pad of required thickness.

Title: Fail-safe master valve
IPC: F16D65/28
Filed: 1965-01-22
Abstract: 1,100,253. Valves. E. HERION. 22 Jan., 1965 [14 Feb., 1964], No. 2863/65. Heading F2V. A fail-safe master valve unit for controlling at least one actuator 19 operable by a pressure medium, particularly for engaging and disengaging the clutch or the brake in the drive means of a press, comprises two separate threeway piston valves 2, 2<SP>1</SP> operating in parallel and being controllable by electromagneticallyactuated pilot valves 6, 7, each piston valve being so contrived that faulty operation results in either valve being urged to follow the opening shift of the other valve by advancing beyond its normal closing position to provide an outlet having a flow path of greater cross-section than the inlet. In normal operation, both pilot valves are energized to connect chambers 10, 11 to a return line 21<SP>1</SP> so that supply fluid from a line 27 separates the valves 2, 2<SP>1</SP> against spring loads 13, 13 to open ports 25 leading through a pipe 18 to the actuator. Simultaneous deenergization of the pilot valves, permits the springs 13 to restore the piston valves to a central abutting relationship in which the actuator is connected to the return line 21 through exhaust ports 14, 15. When only one pilot valve is actuated, the supply port 25 is opened by the corresponding piston valve while the spring of the other piston valve causes it to follow the movement of the first and to open the line to exhaust. An adjustable pressureresponsive switch 31 closes the main supply pipe 27 to prevent an accumulator 30 from discharging. The lines 21 and 21<SP>1</SP> may be dispensed with if the system is pneumatic.

Title: Improvements in or relating to the catalytic oxidation of toluene
IPC: C07C45/36
Filed: 1929-01-29
Abstract: 331,525. Gas Light & Coke Co., Adam, W. G., Shannan, W. V., and Cuckney, M. Jan. 29, 1929. Benzaldehyde; benzoic acid; maleic acid.-Tn the manufacture of benzaldehyde and/or benzoic acid by the catalytic oxidation of toluene vapour with air, the reaction mixture contains a substantial excess of toluene; water vapour and the effluent gases of the reaction may also be included in the mixture. The catalyst may be prepared as described in Specification 331,535, [Class 1 (i), Chemical processes &c.]. As shown, air entering at 10 is mixed with effluent gases in a vessel 13, compressed by a compressor 14, and passed from a storage vessel 16 to a toluene vaporizer 18 and a water vaporizer 19 supplied from reservoirs 11, 12 respectively. The reaction mixture so prepared passes through a preheater 20 to the catalytic apparatus. This comprises a central tube 24, filled with metal turnings to promote the preheating of the mixture, and a vertical annular chamber 22 closely packed with the catalyst, the whole being immersed in a bath of fused sodium nitrite. The reaction products pass by way of the preheater 20 to a condenser 25, from which the condensate passes to a separator 26; a toluene scrubber operated at 70-80‹ C. may be interposed between the preheater and the condenser. From the separator 26 the supernatant toluene layer containing dissolved benzaldehyde and benzoic acid flows to a receiver 29, whence it is passed periodically to a second toluene vaporizer 38, in which it is concentrated; the benzoic acid may first be extracted with alkali. The concentration in the vaporizer 38 proceeds at 70-80‹ C., and it is found that the oxidation of benzaldehyde to benzoic; acid is negligible until the specific gravity of the condensate is about 0.9 at 20‹ C. In practice, the vaporizer 38 is principally used, the vaporizer 18 being supplementary. The aqueous layer in the separator 26, which contains a small amount of maleic acid, is removed from time to time. The gases leaving the condenser 25 are passed through a filter bag 38 dipping into toluene in a vessel 34, which is periodically emptied into the receiver 29. The filtered gases then pass partly to the vessel 13 and partly to a tower 36 containing active carbon. Suitable operative conditions are indicated.

Abstract: 1,147,848. Automatic current control. LICENTIA PATENT-VERWALTUNGS G. m. b. H. Jan. 19, 1968 [Jan.31, 1967], No.3014/68. Heading G3X. [Also in Division H2] A constant-current circuit of a driving installation comprising D.C. motors 10, 11, is supplied from series-connected rectifiers 12, 13, connected to a constant voltage network 14 through a choke coil and a capacitor respectively, the reactances of the coil and the capacitor being substantially equal at the network frequency. The coil 17 may be tapped and the capacitor may comprise two components 18, 19, so that actuation of a change-over switch 20 enables the motor current to be adjusted to two values. Retardation resistors 21, 22, absorb reverse power when the motors operate as generators, these resistors being normally shortcircuited by switches 23, 24, under motoring conditions. The switches 23, 24, are opened only when a predetermined value of current is exceeded, and are closed when regeneration ceases. For providing a dropping speed-torque characteristic, the resistors 21, 22, may be connected continuously or intermittently in parallel with the motor armatures by means of the switches 25, 26, in which case the switches 23, 24, are closed. A falling speed-torque characteristic may also be obtained with the aid of shunt field windings 29, 30, associated with Zener diodes 31, 32, acting as non-linear resistors.

Abstract: 844,674. Coiling helically-jointed tubes; welding by pressure. COMPAGNIE DE PONTA-MOUSSON. Jan. 28, 1959 [Jan. 31, 1958], No. 3032/59. Classes 83 (2) and 83 (4). Metal strip is helically coiled about an anvil to form a tube by reciprocating punch or bender means offset from the anvil towards means for feeding the strip continuously to the anvil. Metal sheet t is fed continuously by rolls 27 to a fixed former or anvil 4, around which it is coiled to form a tube T, by a punch member 13 on a plate 15 reciprocated to and from the anvil 4 by crank means 20. The sheet t is unsupported between the rolls 27 and anvil 4 so that, as it is bent against the anvil by the punch 13, the unsupported part is deflected upwardly and, on descent of the punch 13, springs back to feed the bent part of the sheet around the anvil 4 and over a guide 10. Safety switches 29 and 30, above and below the unsupported part of sheet t, respectively stop the feed of the sheet if the feed is excessive, and the movement of the punch 13 if the feed is insufficient. The helical seam of the wound tube is spot-welded by electrodes 24, 25 mounted respectively on the anvil 4 and punch 13, the A.C. supply thereto being controlled by a contactor 26 actuated by the crank means 20. The feed means 28 or the anvil and bending means 4, 13 are angularly adjustable to alter the direction of the sheet feed. In a modification, Fig. 5, a punch 13a, having a plane or slightly convex face, is adjustable along its plate 15 and a guide 10a is adjustable to and from the anvil 4 for differing diameters and/or thicknesses of tube.

Abstract: 1,140,850. Moulding filters. FRAM CORP. 24 Jan., 1966 [1 Feb., 1965], No. 3166/66. Heading B5A. [Also in Divisions B1, C1 and C3] A filter element 10 comprises particles of an adsorbent retained in a sintered matrix of solid particles individually encased in polymer. The adsorbent may comprise ion exchange resins (examples given), zeolites, diatomaceous earth, activated carbon, alumina or silica gel, Fuller's earth or molecular sieves, or mixtures thereof. The polymer encased solid forms 25- 90% of the mixture, and contains 50-75% of polymer. The polymer may be polyethylene, polypropylene, nylon, Terylene (R.T.M.),P.V.C., polymethylmethacrylate and the solid may be fibrous or granular, wood, cotton, wool, metal, glass, asbestos, carbon or silicates. The cylindrical filter element in Fig. 3 incorporates layers 17, 18 of glass fibres and polyester and glass fibres and vinyl acetate-vinyl chloride copolymer upstream and downstream of element 10. In manufacture, an antioxidant is added to the mixture which is then sintered under pressure in an atmosphere of hydrogen, nitrogen, steam or air. The sintering may be performed in a perforate mould with the gas flowing through the mixture. Alternatively the mixture may be preheated, in the form of a fluidized bed, to within 5 F. of stick point and screw-fed through a hot die, which effects sintering, followed by a cold die which effects setting. The filter may be used to remove suspended solids and dissolved solids, liquids and gases from water, organic liquids, air or gases, the adsorbent being selected according to function.

Filed: 1932-02-04
Abstract: 399,480. Electromagnetic interrupter and light-current relays. STEADMAN, E., WOLSTENHOLME, F. C. and EXCHANGE TELEGRAPH CO., Ltd., 64, Cannon Street, London. Feb. 4, 1932, No. 3332. [Class 38 (v).] In a relay arrangement employing polarized relays successive unidirectional current impulses are arranged to cause the changing over of the armatures of the relays, the change-over being arranged to take place slightly after the termination of the current impulse. As shown in Fig. 1 the current impulses are produced by the closure of contacts 13, 14 completing a circuit through contacts 15, 16 controlled by the armature 1 of a polarized relay 2 and the low-resistance coil 18 of a non-polarized relay 9. The relay 9 now closes its contacts 5, 6, completing the circuit of an operating coil 3 of the polarized relay in series with a high resistance 12. In view, however, of the fact that this circuit is shunted by the low-resistance circuit, including the coil 18, Fig. 3, the current in the winding 3 is not sufficient to change over the armature 1. After the contacts 13, 14 have separated the circuit of the coil 18 of relay 9 is broken but the winding is fitted with a retarding device such as a copper shading ring which delays the release of the armature controlling the contacts 5, 6. Thus, immediately the operating current impulse is terminated by the opening of contacts 13, 14 the low resultant shunt across the winding 3 and resistance 12 in series with the still-closed contacts 5, 6 is removed and the current in this circuit immediately rises to a value which is sufficient to change over the armature 1. The contacts 5, 6 are subsequently disengaged and the arrangement is then in readiness for a subsequent current impulse. The succeeding closure of the contacts 13, 14 completes through contacts 15, 17 of the polarized relay the circuit of the energizing coil 19 of a second non-polarized relay 10, which in turn completes at contacts 7, 8 the circuit of the coil 4 of the polarized relay 2. The change-over operation of the armature 1 then proceeds in a manner similar to that previously described, the parts being restored to the positions shown. A second armature 21 may be provided to be controlled simultaneously with the armature 1, and contacts in a controlled circuit may be operated by this armature. Other polarized relays similarly arranged may be placed in series with the relay 2, Fig. 2 (not shown). Specification 399,148, [Group XL], is referred to.

Abstract: 388,195. Substation circuits. ISENBERG, S., 40, Rue Trebois, Levallois-Perret, Seine, France. Feb. 5, 1932, No. 3497. Convention date, Nov. 12, 1931. [Class 40 (iv).] In a system of recording telephonic conversations, the differences of current strengths received at the recording point from the separate microphones are compensated so that the conversation may be recorded at uniform intensity. As shown in the Figure, the recording circuit is fed by a pair of transformers s, t, the secondaries s<2>, t<2> being connected in opposition and the primaries s<1>, t<1> connected respectively across a subscriber's microphone c and the input transformer d. Speech currents received from the distant subscriber affect both transformers but due to the inoperative condition of microphone c the p.d., across the primary s<1> remains relatively small. Upon transmission of speech currents from the station shown, the voltage across s<1> is increased and the relative effect of the transformers is such that the intensity of the recording-currents is maintained uniform. The relative effects of the transformers and the output current are adjustable by potentiometers h<2>, h. Parasitic sounds may be eliminated by the provision of a grounded screen between the windings of the transformers. In a modification a single transformer having two oppositely connected primaries is provided, one of the primaries being connected to the telephone lines and the other to an auxiliary microphone which produces a compensating effect when the station is transmitting. In a further modification, a resistance is connected in parallel with the input of the recording amplifier, and is adapted to be manually switched into or out of circuit according to whether one or other station is transmitting.
