IPC: A43B3/14
Filed: 1956-12-19
Abstract: 831,696. Moccasins; sewing; sewing machines. JO-AN SHOE MFG CO. Inc. Dec. 19, 1956, No. 38774/56. Classes 17(2) and 112 A method of making a moccasin comprises crimping at 39 the toe portion of a sole and vamp blank 30 and securing it in its crimped state by sewing to it a non- extensible cord 40. This conforms the toe pocket 29 to the peripheral size of a plug 22 and the parts are sewn together as by an overedge sewing machine. A collar 23 is attached to the rear part of the upper and encloses a lace 24. In a modification the plug is sewn to the crimped vamp with the parts inside out and the shoe is then turned so that a smooth external seam is formed. In a further modification, a plug 65, Fig. 15, has a peripheral part 69 extended rearwards in tabs 68 which are later joined at the rear. The sole blank is crimped and pocketed at both the toe and heel and is sewn to the extended plug around the whole periphery. Locating tips 64 are formed on both blanks. A sewing machine for crimping the blank 30 and seaming the cord 40 thereto comprises a serrated feed roll 48 which engages the underside of the blank and crimps it as it passes under the cord 40, which is held by a tensioning device, and a presser foot 53.

Title: Improvements in or relating to Teleprinter Systems
IPC: H04L29/00
Filed: 1967-08-24
Abstract: 1,155,777. Telegraphy. SIEMENS A.G. 24 Aug., 1967 [25 Aug., 1966], No. 39012/67. Heading H4P. A telegraph system has means which, on detection of the clearing signal, introduces a further station to a connection existing between two stations via an exchange. The clearing signal may come from either the calling or the called station, and the exchange prevents the connection from being cleared unless the clearing signal lasts a preset time. In one embodiment when the clearing signal from one station has lasted a first certain time a first relay operates to replace the clearing signal by a continuous Stop signal, so that the other station receives only a short Start pulse, to which it does not respond. After the clearing signal has lasted a second certain time a second relay operates and causes the further station to be connected. At the end of the clearing signal the first relay removes the Stop signal. If the clearing signal lasts even longer (for the preset time) the exchange clears the connection in known manner. In a second embodiment, the clearing signal from one station causes operation of a relay at the further station after a given time has elapsed, causing a short Start signal to be returned to the exchange. This signal causes the exchange to interrupt the clearing signal before the connection can be cleared and to send a short Stop signal to the further station. The start of this Stop signal releases the relay but it is energized again after the lapse of the given time after the end of the short Stop signal, so that again a short Start is returned to the exchange. If a certain number of returned short Start pulses is received the connection is cleared.

Title: Automatic control system for a slide or carriage, more particularly in machine tools
IPC: B23Q16/00
Filed: 1964-10-02
Abstract: 1,075,864. Machine tool control. ROLMA A.G. Oct. 2, 1964 [Oct. 3, 1963], No. 40131/64. Headings B3B and B3C. [Also in Division H2] In a machine, a slide is moved by electrical actuacting means controlled by a sensor 13 co-operating with an adjustable trip cam 11 to actuate a signal transmitter 14, 15 through means 50, 51, adjustable to determine the point at which no signal is transmitted, the signals from the transmitter being such that the slide moves to, and stops at, a selected position. A work-table 3 and a cross-slide 2 are moved by motors Mx, My driving rolling tape gear 4a, 4b, 5 and 8a, 8b, 7 and associated drums Wx, Wy carrying control trip cams 11. In operation, if a sensor 13 for controlling the table 3, say, is resting on the lower surface 11a of the cam, the switch 14 is open and the switch 15 is closed. When a switch 58 is closed, the table is moved by its motor until the sensor rides up a rise 12 of the cam to open the switch 15 and stop the slide. To allow for overshoot when the motor stops, the apparatus is set so that the switch 15 is opened just before the centre of the rise 12 is reached. When another movement is required, the appropriate switch 58 and/or reversing switch 59 is operated. All of the switches 58 may be combined in a rotary switch to prevent more than one switch from being operated at a time. A spring-operated table clamp is released by an electromagnet controlled by a relay 57. If, when a switch 58 is closed, the sensor is on the high part 11b of the cam, the switch 14 is closed and the table is stopped when the switch is opened, the switch 15 being then always open, and over-shoot being allowed for. Two workpieces (68a, 68b), Fig. 4 (not shown), may be mounted on the table 3 which has a coolant trough (65) which empties over an edge (66). The separation (a) between the workpieces corresponds to the spacing between rises 12 on a cam. Thus, by using a reversing switch 59, one set of cams can be used for the drilling of both workpieces. In modifications, trip cams replacing the rotating cams are placed on the slides; the switches 58 are programmed; or a slide is moved in fast motion and control means are provided to reverse the slide at creep motion when it has overshot its desired position. In a further modification, control is exercised through clutches instead of the motors.
