Title: Improvements in or relating to forms such as diaphragms and processes and apparatus for producing same
IPC: H04R31/00
Filed: 1932-12-12
Abstract: 411,825. Diaphragms. RAFFLES, F., 400, W. Erie Street, Chicago, U.S.A. Dec. 12, 1932, No. 35241. [Class 40 (iv).] Pulp forms, such as acoustic diaphragms, lampshades, containers and ornaments, are produced by immersing one or more porous or perforated moulds 36 secured over openings 26 in a plate 20 in a mash 12 of paper or wood pulp, cotton, wool, fur or asbestos in a tank 10, suction being applied to the moulds through pipes 30 by a vacuum pump 32 and the plate 20 being attached to a support 22 by a hinge or universal joint 24 so that the angle at which the mould enters the pulp or is disposed relatively thereto. during the process can be adjusted. The pulp, to which suitable sizes and dyes may be added if desired, is uniformly distributed and suspended in the water by means of paddles 14. on a suitably driven shaft 16. Water is returned to the tank from the pump 32 through a pipe 34 and fresh pulp is added through a feed pipe 54 controlled by a valve 56 which may be automatically controlled by a float in the tank or by a lever system attached to the means for raising and lowering the plate 20. The motion of the plate into and out of the pulp may be made continuous but sufficiently retarded when the plate is out of the pulp to enable the forms to be stripped from the moulds or the mechanism for raising and lowering the plate may be so arranged that suitable intervals of rest are provided above or below the pulp level. Mechanical means can also be provided for controlling the depth and time of immersion of the plate 20. Various methods are described for stripping and drying the forms. Thus, the pump 32 can be cut off by a valve 44 after the plate 20 has been removed a sufficient time from the tank or the moulds may be made quickly releasable and removed from the plate and replaced by further moulds, the forms being dried on the original moulds by suction or heat. Alternatively and as shown, the forms can be transferred to counterpart moulds 46, 48 carried by a plate 50 and connected to pipes 52, the suction in which is greater than that in pipes 30. Again, the wet pulp form may be transferred to a male die in a press and a female die brought down over it, both dies, if desired, being heated and suitably embossed. The pressure applied to the pulp fibres can be controlled by adjusting the clearance between the dies whilst, if desired, one part of the form, such as the conical portion of a diaphragm, may be made rigid while the suspension portion around the cone is formed flexible and softer and/or thinner. The vacuum operating on a mould may be controlled so that the suction on one part thereof is less than that acting on the rest of the mould, or valves may be associated with the moulds so that the deposit of pulp on any particular area may be controlled when the plate 20 is immersed. Alternatively, one or more stoppers may be applied to the mould after a predetermined time to prevent further deposit of pulp on particular areas.

Dec. 3, 1938, No. 35248. [Class 32] [Also in Group IV] Waste waters containing phenols are dephenolised by injecting the waste water into the high pressure circulation system of a destructive hydrogenation plant at a point behind the reaction vessel, the phenolic substance being dissolved in the hydrogenation products and thus extracted from the water. The water mav be that obtained in the destructive hydrogenation reaction itself, or waste water obtained in the low temperature carbonisation of hydrogenation residues. The water is preferably added at such points in the system where congestion is liable to occur owing to the deposition of salts. In a destructive hydrogenation plant comprising a reactor 1. hot catch pot 4, cooler 6, and cold catch pot 7, the condensate collecting in the pot 7 is passed through a pressure release valve 10 to a separator 11 where water is removed through line 12 and then distilled with steam in a tower 14 the vapours passing through a cooler 17 to vessel 18 where water is separated. The sludge from the hot catch pot 4 is returned in part through line 25 to reaction vessel 1, the remainder after release of pressure being carbonized in the low temperature plant 27, and the vapours evolved condensed in cooler 29 and separated from water in separator 30. The water drawn off from separators 30, 18 is pumped by pumps 19, 33 through lines 34, 20 and injected through line 21 into the line 5 between the catch pot 4 and cooler 6. Extraneous water may be injected through line 35.

Abstract: 1,236,558. Selective punching machines. VILLAMOS AUTOMATIKA INTEZET. 16 July, 1969 [16 July, 1968], No. 35905/69. Heading B4B. A selective card punching machine comprises a plurality of punches 3 divided into three groups which are simultaneously operable to punch information on to a punch card inserted into the machine, the punches of a first group being arranged to provide constant information, the punches of a second group being selectable by means of a perforated pattern 37 and the punches of the third group being selectable by means of a stepping mechanism. The punches co-operate with a die-plate 1 which is slidably mounted on guide pins 5 secured to a frame 4. A space for the reception of the punch card is provided between the die and a guide-plate 2 which is slidable on the pins 5 against the action of springs 14. A plate 6 is secured to the frame and is formed, in the area thereof above the first and second groups of punches, with a space into which a solid and a perforated plate may be fitted. The solid plate is positioned above the first group of punches so that at every punching operation a hole is pierced by these punches. The perforated plate is located above the second group so that only those punches not in line with a perforation in plate will pierce a hole in the card. The punches in the third group are selected by means of interposers 17 formed on toothed racks 18, one rack being located in a slot in the plate 6 for every column of ten punches in the third group. Each rack is moved, in order to bring the interposer 17 into line with the selected punch, by means of a pawl 22 connected by links 25, 27 to the armature of an electromagnet 28. The link 25 is pivoted on a fixed pin 24 so that at each energization of the solenoid, the pawl engages with a tooth on the rack and upon de-energization, the rack is moved one-tooth pitch by means of a spring 26; the rack is retained in this position by a locking element 20. When the interposer 17 on a rack reaches the last punch in a column, the end of the rack engages a switch 34 which energizes a second electromagnet 33 thereby releasing the locking element 20 via links 29, 31, 32 so that the rack returns to its starting position. A pair of electromagnets as described are associated with each rack in the third group of punches, the energization of the magnets being selectively controlled by a suitable counting device. The die is moved towards the punches by means of a parallel-linkage arrangement 41 to 47 actuated by means of an electromagnet 48.

[A Specification was laid open to inspection under Sect. 91 of the Acts, June 23, 1933.] [Class 38 (ii).] A conductor 7, at a negative potential, produces an electrostatic field which suppresses the discharge through the tube 10, distortion of the field, e.g. by the introduction of a conducting body into the field, initiating the discharge. In one application of the invention, periodic interruptions are produced by a conducting member 11 distorting the field, initiating the discharge to energize the winding 12 which withdraws the member 11 from the field to suppress the discharge, thus de-energizing the winding 12 and allowing the member 11 to move into the field and initiate the discharge again. The tube 10 may have an argon or metallic filling and a conductive coating on its inside or outside walls. It may be operated with alternating current of higher periodicity than the switch 11, or may be used to convert direct current to alternating current. In a modification, the member 11 is dispensed with and the relay 12 closes a switch in the lead to the conductor 7, Fig. 2, not shown. Specification 390,307, [Group XL], is referred to.

[Also in Group XXIV] Intermittent reciprocation of a rotating spindle a, which may carry a valve-lapping tool t, is effected by the periodic interference between the wedge-shaped end of an arm h on the rotating spindle a with the end of an arm j, Fig. 2, on an axially fixed spindle c which is rotated at a different speed so that interference only occurs after a plurality of revolutions. As shown, two spindles a, b, each carrying a lapping tool, are rotated by a belt g in the opposite direction to the spindle c. The arm j coacts with the arms h, i on the spindles a, b to raise them periodically, return being effected by gravity, spring, hydraulic or pneumatic means. Slip in the belt drive may provide irregular reciprocation and where this is not desired the belt may be replaced by a chain drive. The tool t is held in a chuck m whose arbor n loosely engages a bore in the spindle a, so that the lapping pressure is determined by the weight of the tool and chuck. This weight can be varied or can be supplemented by springs in the spindle bore. Threaded rings q on the spindle are adjusted to lie just below a retaining pin o on the chuck arbor to lift the tool t when the spindle a is raised.
