Title: Platen press having curved impression member
IPC: B41F1/00
Filed: 1948-08-20
Abstract: 675,184. Printing-machines; embossing or scoring machines. CHANDLER & PRICE CO. Aug. 20, 1948 [Sept. 27, 1947], No. 22049/48. Class 100 (ii). Platen presses in which curved printing or impression members act by line contact to print, emboss, or score a sheet of material by a pivotal or swinging movement of the type or impression member on one of the frame members of a press such as a Gordon or Golding type of press, are constructed so as to minimize jarring which occurs at the commencement of the printing &c. action. The invention is described in connection with machines as in Specifications 642,202 and 666,969. In Fig. 1 a machine as in the latter Specification is constructed with a pivoted type bed 13 mounted in an oscillating frame 2 movable towards a curved platen 4 which is locked in the position shown after being rocked to receive a sheet. In this position the frame 2 is moving the bed 13 towards the platen, but before the type forme 14 contacts the platen 4 the bed 13 is moved clockwise about a pivot 21 at a rate which is somewhat less than that at which the frame 2 is advancing it towards the platen, so that the bed is moving slowly relatively to the platen as it contacts the platen, and so jarring is avoided. The bed movement is controlled by a cani surface 25 on it which engages a roller 26 on a pivoted member 27 controlled by a roller 29 and a cam surface 30 on a lever 33 which is oscillated by a cam 35 on the crankshaft 9 which oscillates the frame 2. In Fig. 5, as applied to a machine as in Specification 642,202 in which the platen 39 pivots about an imaginary axis 43 while the type bed 13 is carried by the oscillating frame 2 to move over the curved platen, the platen is moved counter-clockwise about its pivot 5 by means of a cam 54 on the crank-shaft 9, which engages a roller 53 on ears 52 attached to the platen. The platen is also controlled by arms 46 having curved parts 45 which engage ears 44 on the platen, and by arms 49 having rollers 50 engaged by slots 51 in the ears 52. As the bed 13 approaches contact with the edge 42 of .the platen, the platen is moved by the cam 54 to withdraw the edge away from the bed at a rate which is slightly less than the speed of approach of the bed 13, so that ultimately contact occurs with a slight relative motion, and thus jarring is avoided.

Title: Improvements in or relating to apparatus for use in underwater seismic exploration
IPC: G01V1/38
Filed: 1954-08-03
Abstract: 751,568. Geophysical prospecting; depth measuring. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Aug. 3, 1954 [Aug. 3, 1953], No. 22480/54. Classes 40(1) and 118(2)) Apparatus for use in underwater seismic exploration comprising a cable adapted to be streamed under water and having a flexible tubular envelope containing at points spaced along its length a plurality of seismic detectors is provided with two or more depth gauges in the form of pressure sensitive elements contained within the flexible cable envelope, which is filled with a liquid, e.g., oil, to increase buoyancy and transmit the hydrostatic pressure from the sea to the said depth gauges. The seismic delectors are preferably piezoelectric microphones and are operated in known manner. Each depth gauge comprises a flexible diaphragm (e.g., rubber) exposed on one side to the liquid within the envelope and mechanically coupled on the other side to an armature of an electromagnet such that magnetic attraction would oppose the hydrostatic pressure. An adjustable back-stop is preset to limit the gap between armature and core to about 0.005 inch. In use the pressure to be measured holds the armature against its stop at the preset separation from the core. At the surface (i.e., on the towing vessel) a battery 63, milliammeter 65, rheostat 67 and primary of a transformer 69 are connected in series with a return lead common to the magnetizing windings 49 of all depth gauges and a selector switch 61 which selects the other lead particular to the depth gauge to be investigated. The rheostat 67 is initially set at a high value and then gradually reduced so as to increase the current in the depth gauge electromagnet 49 until the attractive force on the armature balances the hydrostatic pressure on the flexible diaphragm, whereupon the armature moves into contact with the core and induces a transient electric current in the circuit. This pulse is fed by the transformer 69 to the grid of a thyratron 71 which fires to light an indicator lamp 73. This indicates to the operator that the reading of the milliammeter 65 at this instant corresponds to the pressure to be determined and this pressure may be found from a previously compiled calibration curve, the depth then being obtained from a knowledge of the water density.

Title: Improvements in and relating to torsion springs
IPC: B60G11/52
Filed: 1939-08-05
Abstract: 542,409. Torsion springs. VOIGT, C. A. Aug. 5, 1939, No. 22733. Convention date, Aug. 6, 1938. [Class 108 (iii)] A spring unit, for transmitting torque stresses comprises a metal torsion spring which is anchored at its heads to the parts whose relative angular displacement applies the load to the spring, and is embedded in rubber to damp the spring action. In the form shown in Fig. 1, the torsional spring unit comprises an outer sleeve 1 and an inner sleeve or shaft 2 connected by a spiral spring 3. A rubber member 6 is arranged between the parts 1 and 2 so as to enclose the spring 3 and is in an unstressed condition when the spring is deformed by an amount corresponding to the average load. At increased loads, the spring 3 tends to compres the rubber thus giving an increased hardness of springing with increased load. In another form, Fig. 2, a helical spring 13 attached to two relatively rotatable members 8, 11 is embedded in a rubber block 14 rigidly cemented to conical flanges 9, 12 carried by the members 8, 11. Alternatively the rubber block is left unattached to the rotatable members. Fig. 3 shows a form in which the metal spring 29 and the surrounding rubber block 30 extend between and are attached to concentric relatively rotatable members 25, 27. The block 30 is connected to inner and outer sleeves 26 which are respectively keyed to the shaft 25 and attached by screw 33 to the sleeve 27. As shown in Fig. 4, the spring 29 is replaced by a torsion bar 39 and the rubber block 38 which is cemented to the torsion bar is of conical form in order that there shall be equal stress in all cross sections of the block. The Specification in its original form as open to inspection under Sect. 91 describes also a modification in which the helical spring of Fig. 2 is replaced by a straight torsion-rod passed through the bore of the rubber block. This subject-matter does not appear in the Specification as accepted.
