Title: Method for the alignment of machine parts
IPC: B21B38/00
Filed: 1974-05-20
Abstract: 1467325 Aligning machine parts PAPIERFABRIEKEN VAN GELDER ZONEN NV 20 May 1974 [21 May 1973] 22492/74 Heading G1M The long axes of rollers in a rolling machine may be optically aligned in a known manner by establishing a base line parallel to the longitudinal centre line of the machine or line of rolls, lining and sighting a theodolite along this line, and then turning the theodolite through 90 degrees about a vertical axis to line up with the long axis of each roller in turn, the deviation of each roller being measured by determining the distances between a vertical plane along the base line and the two ends of the roller. In the present invention, Fig. 1, any vertical plane of reference which is parallel with the vertical plane along the base line 4-5 may be used, the theodolite being lined up along the base line by observing the imaged reticule of the theodolite in a mirror 6 or other reflector or prism placed at the end of the base line and at right angles to it, the actual reticule and its image being made to coincide, or its actual vertical line being brought into correspondence with the imaged vertical line. The reticule may be illuminated by optical fibres, or a laser beam may be used to adjust the theodolite, and the mirror or other reflector 6 allows a large degree of movement or adjustment to be given to the theodolite. In Fig. 2 the roller 3 supports a tab 10 comprising a vane 14, a magnetic foot 11 and a level 13, the theodolite being sighted on to one of a series of ringed reference marks arranged vertically or horizontally on the vane, 14, Fig. 3 (not shown) instead of on to an actual end of the roller. The apparent distance between this reference mark and the vertical reference line of the theodolite viewer is determined preferably by making use of a transparent plane-parallel plate which can be rotated in front of the viewer by means of a micrometer screw to adjust the image of the vertical line of the reticule into coinciding with the reference mark and thus give a reading. Thereafter vane 14 is attached to the roller near its other end and a further distance reading taken between the vane mark and the vertical reticule reference line, the difference between these two readings being a measure of the deviation in a horizontal plane.

Title: A method for the circular knitting of partially reinforced hosiery goods and a circular knitting machine for carrying out this method
IPC: D04B9/46
Filed: 1959-07-01
Abstract: 872,375. Knitting. SCHUBERT & SALZER MASCHINENFABRIK AKTIENGESELLSCHAFT INGOLSTADT. July 1, 1959 [Nov. 13, 1958], No. 22547/59. Drawings to Specification. Class 74 (2). A stocking having a reinforced heel and toe and if desired a reinforced sole is knitted by continuous rotary knitting on a stationary or rotary needle cylinder machine. The reinforcing yarn is incorporated in a continuous length without subsequent cutting by providing the machine with two superposed cam systems one of which rotates in the opposite direction to the other in the case of a stationary needle cylinder machine or rotates twice as fast as the needle cylinder in the case of a rotating needle cylinder machine. This arrangement enables the ground yarn to be continuously knitted during the continuous rotation of the cylinder or of the ground yarn feeder and cam system and during part of each revolution have incorporated with it the reinforcing yarn. During the next part of each revolution the other cam system and reinforcing yarn guide effect operation of the selected needles in the reverse order whereby the reinforcing yarn is knitted back alone within the reinforced area of the stocking.

Title: Improvements in or relating to power law function generators and to other function generators which include at least one power law function generator
IPC: G06G7/20
Filed: 1957-07-17
Abstract: 853,554. Semi-conductor circuits. GENERAL ELECTRIC CO. Ltd., and WALKER, P. M. July 15, 1958 [July 17, 1957], No. 22602/57. Class 40(6). [Also in Group XXXVI] A power law function generator of the kind comprising a non linear (e.g. a silicon-carbide resistor) impedence obeying a law I = KVα connected to an input terminal through a linear resistance and to an output terminal through a further linear resistance and an adding feedback amplifier, is provided with a second input path comprising at least one other non-linear impedance to compensate for variations in α at low input voltages. A square law function generator 1 is shown in Fig. 1 comprising an input terminal 4, potentiometer 3, 5, non-linear resistor 2 (α#2), a further potentiometer 6, 10 and an adding amplifier 7 having a feedback resistance 8, the second input path being shown outside the dotted rectangle 1 and comprising two further non-linear resistors 17, 22 and a sign changing device 12. Considering the potential at point 20 in the potential divider, comprising a resistor 16 and a non-linear resistor 17 with a resistor 18 in parallel and a resistor 19 in series therewith, the voltage at 20 will initially be positive and increase positively with the input voltage V. As V increases further the voltage at 20 will fall until the resistance between point 20 and the input terminal by way of resistor 16 and the resistance between point 20 and point 23 are equal when the voltage at 20 will be zero. The potential divider 11 will therefore apply a small correcting current to amplifier 7 over a certain range of input voltage V, the resistor 21 and the non- linear resistor 22 further modifying their correcting current and ensuring that the square law curve generated has zero shape at the origin. The sign of the output will change with the sign of V but diode switches may be used to overcome this. If it is desired to generate a power law having an index higher than α for the silicon carbide discs two or more generators may be arranged in cascade (Fig. 6, not shown). A square root law generator may be provided by including the components shown inside rectangle 63 of Fig. 1 in the feedback path of an amplifier.

Filed: 1946-07-31
Abstract: 619,534. Determining moisture-content of materials; variable condensers. FIELDEN, J. E. July 31, 1946, No. 22802. [Class 37] An apparatus for measuring the moisture content of a material, uses the material as the dielectric of a condenser in a bridge circuit, the change in dielectric causing a potential difference which is amplified and shown on a meter calibrated to indicate percentage moisture content of the material. A modulated H.F. current is fed into a screened transformer e, f whose primary windings are symmetrically arranged to avoid inaccuracies due to stray electrostatic coupling, and the balanced secondary is fed to two condensers in series g and h, the latter consisting of two disc electrodes surrounded by a guard ring, and secured by insulated bolts to a pair of brackets capable of being attached to the machine carrying the material being tested, the material being introduced between the two electrodes. Potentials developed at the junctions p of the two condensers due to changes in the dielectric of condenser h are amplified, demodulated and the low-frequency content is amplified and finally rectified to produce a reading on a meter q. The apparatus can also be used to measure the mass of a textile, or any other property of a material which will affect the dielectric constant.

Title: Improvements in or relating to pressure regulators for gas mains
IPC: C10B27/06
Filed: 1921-09-01
Abstract: 189,249. Jackson, W. J. Mellersh-, (Koppers Co.). Sept. 1, 1921. Pressure-regulating valves.-A pressure-regulating device particularly applicable for use on the collecting mains of by-product coking plants, comprises a butterfly-valve in the main actuated by oil pressure acting on a pair of pistons under the control of a piston-actuated relay valve, itself controlled by an auxiliary valve actuated by a liquid-sealed bell. The main actuating-pistons 81, 82 are mounted on a common rod pivoted at 84 to a slotted arm 85 mounted on a rock shaft 87 which carries a second arm adapted to actuate the main valve. The supply and exhaust of pressure fluid to and from the cylinders 77, 79 is controlled by the relay valve 57, which comprises a pair of valve pistons 67, 68 connected by a trunk having longitudinal passages 80 and adapted to be actuated by a pair of differential pistons 64, 66. The space between the valve pistons is connected to an inlet 71 for pressure fluid, while the chambers on each side of the pistons are connected to an exhaust passage 72 connected to a reservoir 92 below the main cylinders, the chambers 74, 75 being connected to the cylinders 77, 79 respectively. The piston 66 is subject to a constant fluid pressure, while the larger piston 64 is subject to a variable pressure controlled by a pilot valve 44. This pilot valve has balanced piston valve member adapted to place the port 52, which communicates with the cylinder 64<a>, either in communication with a pressure inlet 49 or with an exhaust passage 51. The pilot valve is connected by a rod 43 to a hunting lever 42 operated at one end by a cam 104 on the rock shaft 87 acting through a spring-loaded rod 105, and connected at the other end by a rod 41 to a liquid-sealed bell 27 subject to the pressure in the main conduit admitted through a pipe 24. The bell is fitted with an annular buoyant chamber 30 and with an annular chamber 28 adapted to be filled or emptied through a valve-controlled port in the side of the bell as the bell falls or rises to retard its movement. The movement of the main pistons is retarded by means of a, piston 98 linked to the lever 85 and arranged to work in a cylinder 97 connected at 101 to the pipe supplying pressure-fluid to the cylinder 77, and 92 at 102 through a valve-controlled port with the reservoir 92, so that when the piston is 'moving under pressure the piston 98 tends to suck oil from both the tank 92 and the pressure supply pipe. The reservoir of oil under pressure for operating the system is filled from the tank 92 by means of an electrically-driven pump stopped or started by a switch actuated by the pressure of the air above the oil so that a constant pressure is maintained. A valve controlled by-pass pipe may be fitted between the two reservoirs so that the pressure tank may be emptied without running the oil through the system.
