Title: Improvements in or relating to machines for applying coating materials to workpiecessuch as shoe parts
IPC: A43D25/18
Filed: 1952-03-26
Abstract: A machine for applying coating materials to work-pieces such as shoe parts, e.g. liquid cement to the upper surfaces of platform wedge heels, has a coating roll, a feed roll, means for driving the coating roll, a mounting for one of the rolls arranged to allow it to move away from the other roll as a work-piece of increasing thickness passes between them, and means arranged to retard any sudden movement of the movable roll towards the other roll as the work-piece passes away from between them.  As shown, a coating roll 14, dipping in a pool 16 of liquid cement, is fixed to a shaft 12 journalled in a base 10 to rotate about a horizontal axis.  A frame 20 is hinged to the base 10 about an axis parallel to that of the roll 14, on a fixed rod 22 which extends through ears 24, 26 on the base, <PICT:0735871/III/1> <PICT:0735871/III/2> <PICT:0735871/III/3> <PICT:0735871/III/4> and through bearing portions 28 and 30 on the frame 20.  A shaft 32, journalled in the frame 20 and an extension 34 thereof, carries a peripherally-toothed feed roll 36 and two narrow auxiliary rolls 38 and 40, the hinged connection of the frame allowing these to rise bodily away from the coating roll 14.  The shaft 12 may be driven, as by a belt 62 acting on a pulley 60, and the shaft 32 driven from a gear 58 mounted on the shaft 12, this gear engaging a gear 56 fixed to a shaft 50 journalled in ears 52, 54 on the base 10; the shaft 50 carries a gear 48 which meshes with a wide gear 46 mounted on the shaft 22, the gear 46 also meshing with a gear 44 on the shaft 32.  The pressure of the roller 36 on the work-piece 70 is augmented by a spiral spring 73, the ends of which are secured to the frame 20 and the shaft 22 respectively; the pressure may be adjusted by rotating the shaft 22 by a knob 75 and then securing it in the ear 24 by a set-screw 74.  A table 64 and guides 66 and 68, preferably resilient strips of steel, are provided for the work-piece 70, which as shown is a platform wedge heel; the increasing thickness of this forces the roller 36 upwards, rocking the frame 20.  The return movement of the latter is retarded by a dashpot device comprising a hollow cylinder 80 rockably mounted on a bracket 84 extending from the base 10, and in which a piston slides, the piston-rod 82 being pivotally connected to a bracket 86 on the frame 20.  U.S.A. Specification 2,341,160 is referred to.

Title: Electro-magnetic Devices for Use in Signalling Circuits.
Inventor: GHEGAN JOHN JOSEPH
IPC: H04L15/28
Filed: 1918-05-10
Abstract: 126,470. Ghegan, J. J. May 10, 1918. Morse and like sounders and recorders.-The circuit of an electro-magnetically operated sounder is controlled by a direct-current relay in the signalling circuit and is energized by alternating current derived from power mains. The controlled element of the sounder normally rests against one stop and strikes against the other when the sounder is first energized, but upon the continued energization of the sounder the controlled element occupies an intermediate position from which it moves to strike the rest stop upon de-energization. In the arrangement shown in Fig. 1, a relay r in the signalling circuit o controls the circuit of the sounder magnet m which is energized from power mains e through a transformer p, s. When the magnet m, Figs. 1 and 2, is de-energized, the controlled element b is caused to engage a fixed stop 6 due to the action of a compression spring 21. When the magnet m is first energized, its armature a is raised and, due to the inertia of the moving parts, the element b carrying a stop 7 is moved until the stop 7 strikes the anvil 44. Upon the continued' energization of the magnet m, its armature a is moved into the maximum magnetic field of the magnet m in which position the element b occupies an intermediate position. Upon the cessation of the energization of the magnet m, the element b strikes the stop 6 to denote the end of the signal element. In the modification shown in Figs. 3 and 4, the magnet m is in the form of solenoids, the cores of which are connected by a yoke a, the position of which is adjusted by a pin q, spring 22, and a screw 23. The controlled element 40 carries a stop 7 and a screw 47 through which the pin q passes. When the solenoids m are de-energized, the spring 22 causes the element 40 to engage the stop 6. When the solenoids m are energized, the yoke a is lowered and a spring 25 causes a stop 7 on the element 40 to engage the anvil 44, during which time the yoke a is vibrating but out of contact with the element 40. At the end of the signal element the solenoids m are de-energized thereby allowing the element 40 to engage the stop 6.

Abstract: 756,474. Digital electric calculating apparatus. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. March 18, 1954 [March 19, 1953], No. 7960/54. Class 106 (1). A binary series-mode electronic device, having input and output terminals and referred to as an algebraic code converter, operates with ndigit words, the first digit of each word being a sign digit for a binary number represented by the following n-1 digits, and is characterized in that the application of a negative number - N to the input causes a negative number - (2<SP>n-1</SP>-N) to be transmitted to the output terminals while positive numbers are transmitted unaltered. In the example described a 10-digit word, Fig. 2 (a), representing - 216, the digit in the first place being the sign digit and that in the tenth place being the most significant, is applied at the input terminal 1, Fig. 1, of the device and as a result of this the negative number -(2<SP>9</SP>-216)= - 216, Fig. 2 (f), is transmitted to the output terminal 19. The input word is applied direct to a normally open gate 8 and its inverted form, Fig. 2 (b), produced by a inverter 6 is applied to a gate 9, gates 8 and 9 being controlled inversely by a combined coincidence detector and trigger device 14 which, when coincidence is detected closes gate 8, and which is reset at the end of each minor cycle. If the sign of the input number is positive gate 8 remains open for the whole word, but if the sign is negative, gate 8 is open up to and including the first significant " 1 " of the number, after which it closes and gate 9 opens to transmit the remainder of the word in inverted form. Examination of the sign digit is effected by a device 12 to which is applied via terminal 10, a controlling " minor cycle pulse," Fig. 2 (c), and which, having detected a negative indicating sign digit issues a series of " 1 " pulses, Fig. 2 (d) for the remainder of the minor cycle, thus conditioning the device 14 for detecting the first significant " 1 " of the number. A more detailed description of the device is also given, using crystal diode gates and buffers and one-digit-delay circulatory triggers.
