Title: Heel Attaching and Sole Laying Machine
IPC: A43D75/00
Filed: 1967-02-16
Abstract: 1,173,792. Attaching soles and heels. MASCHINENFABRIK MOENUS A.G. 16 Feb., 1967 [16 Feb., 1966], No. 7533/67. Heading A3B. A machine for attaching the heel and sole to a shoe comprizes a heel attaching device and a sole attaching device mounted in a single machine under common control so that the heel and sole can be applied successively. The heel attaching device is hydraulically operated and comprises a last support 9 with a sleeve 6 into which a nail, drive screw or screw nail is inserted, and a pair of opposed hydraulic cylinders 13, 14 to' clamp the heel to the shoe and the lower cylinder 14 also drives the nail etc. The flow of fluid, e.g. oil to the nailing cylinder 14 is cut-off until the clamping cylinder 13 has reached a prescribed pressure. The nail is driven into the heel by a d bolt 16 in the sleeve 6. After attachment of the heel hydraulic cylinders 25, 26, are activated to' move the support 27 against the shoe and swing the pressing pad 32 against the sole. Compressed air is then passed to the pad 32 to expand it against the sole. A time relay opens valves 8, 20 and a set time interval and the pad 32 is exhausted and the machine returns to its initial position. The pressure may be regulated by a pressure relief valve 29. The machine operates only on one shoe, but may be duplicated to attach the heels and soles to a pair of shoes simultaneously.

Title: Method of producing composite bushings
Inventor: TIMINERMANS FRANZ DONATUS
IPC: F16C33/14
Filed: 1969-02-12
Abstract: 1,262,160. Making bearings, gauging stops, work holders; casting processes. F. D. TIMMERMANS. 12 Feb., 1969, No. 7611/69. Headings B3A, B3F and B3W. [Also in Division F2]  A method of making split bearings, each consisting of two steel shells lined with an alloy, comprises longitudinally dividing a starting cylinder a of steel lined with an alloy into segmental units m and pressing each unit into a part-cylindrical shell. Chips of lead-bronze, which constitutes the alloy, are placed in the cylinder. The cylinder is rotated and heated in an induction coil to about 1100‹ C. for coating with the alloy and when coated is cooled in a lead or alloy bath. Alternatively the cylinder is partly cooled in the bath and returned to the coil, which is provided with means for spraying water on to the cylinder. The cylinder may be split axially into and rolled flat into sheets prior to being cut into segmental units, Figs. 5, 6 (not shown). The sheets may be rolled hot, in which case two sheets separated by a layer of carbon filled paper may be rolled together or one sheet may be rolled on a steel plate, which also passes through the rolls and acts as an anvil. The rolling temperature depends on the quantity of lead in the alloy, but it is preferred to roll at the red heat of the steel. The sheets may be rolled cold after hot rolling, or hot rolling may be dispensed with. When the cylinder itself is cut, it is held by a clamp n, which moves pivotally in steps, and a shear blade k cuts off the units m. After each cutting step, the cylinder is rotated until the cut edge abuts a stop j. The units are shaped in apparatus b, c, the transverse curvature of the unrolled units being eliminated as they are formed into bearing shells.

Title: Improvements in or relating to electron discharge devices
IPC: H01J29/56
Filed: 1940-05-02
Abstract: 543,022. Cathode-ray tubes. McGEE, J. D., MILLER, H., and FREEMAN, G. S. P. May 2, 1940, No. 7891. [Class 39 (i)] The cross section of an electron beam is changed by passing the beam between one or more pairs of plates which are maintained within a strong uniform magnetic field and between which an electrostatic field is formed. The magnetic field is in the same direction as the beam when it issues from a gun 1, Fig. 2, to pass between plates 2, 3 of narrowing width ; reflector electrodes 4, 5 cause the beam to pass backwards and forwards a number of times the displacement along the plates being due to the actions of the two fields. The plates may be triangular in shape or have extensions a, b at each end to enable the output diaphragm 6 and gun 1 to be spaced widely apart. If the gun and diaphragm 6 are nterchanged the beam instead of being reduced will be enlarged in cross section. The beam when it is out of the influence of the plates travels in a direction parallel to its original path. Two such sets of plates may be used in segments to alter the dimension of the beam in one plane ; or one pair 12, 13, Fig. 4, may alter the dimension in one plane and a second pair 14, 15 in a plane at right angles to the first pair. The spaces apart of the pairs of plates may vary. To limit the region in which the beam is returned to a direction parallel to its original path two sets of plates 16, 17, and 18, 19, Figs. 6 and 7, are used with potentials reversed with respect to each other. Two sets of plates with their main dimensions in plates perpendicular to each other and each set consisting of four plates as in Figs. 6 and 7, may be used to reduce the beam to a small size. The plates may have curved ends as described in Specification 542,219. The device may be used with apparatus as described in Specification 542,488.

Filed: 1932-03-21
Abstract: 398,871. Television. FERNSEH AKT.- GES., Goerzallee, Zehlendorf, Berlin. March 21, 1932, No. 8376. Convention date, March 27, 1931. [Class 40 (iii).] In a television system in which all or a portion of the receivers have motors fed from the same mains as the transmitter motor, more accurate synchronization is effected by the provision at the transmitter and/or any or all of the receivers of means for keeping constant the phase of such motor or motors. In practice it is found that this phase constancy is maintained with sufficient accuracy by keeping constant the terminal voltage of the motors, e.g. by inserting between the mains and the motors any known form of automatic control for this purpose. In the system illustrated diagrammetically in Fig. 1, the network 2 is supplied with alternating current from a station 1 and feeds both the motor 3 driving the picture analyzing device 4 at the transmitter and also the motors 5 driving the picture composing devices 6 at the receivers. When such a system is complete in itself, the phase or voltage either of the motor 3 or of the motors 5 or of both may be maintained constant ; when, in addition, there are other receivers not connected with the network 2, e.g. the receiver 10 incorporating a synchronized direct current motor 9 supplied from a station 7 through a network 8, it is necessary to maintain constant the phase or voltage of the transmitter motor 3. The known devices employed for keeping constant the terminal voltages of the motors 3, 5 may comprise iron-hydrogen resistances, Fig. 2 (not shown), inserted between the mains and motors, chokes, Fig. 3 (not shown), having air-gaps of varying widths, or adjustable resistances acting on the Tirril principle. According to the Specification as open to inspection under Sect. 91 phase correction of the motors may be effected by selenium or photo-electric cells at the receivers operating in conjunction with synchronizing signals from the transmitter. This subject-matter does not appear in the Specification as accepted.
