Abstract: 228,148. Puening, F. Jan. 23, 1924, [Convention date]. Heating-apparatus.-In heating-apparatus of the kind in which a body of heating-gases is passed alternately in opposite directions through a heating-chamber, the impelling member for the hot gases consists of a bell 1 vertically-movable in a chamber 12, and water-sealed at its periphery and around an opening 19, which connects the space above the bell with one of the conduits 22 leading to the chambers 25, 25<a> to be heated. The other conduit 16 connects with the space beneath the bell. In each heating chamber fresh combustion products are supplied to the stream of reciprocating gases from a combustion chamber 29 or 42, delivering at about the mid point of the flow passage, and automatically-operated dampers 48, 49 are provided to permit the escape of a corresponding volume of heating-gases. Either of the heating-chambers can be put out of action by dampers, and the stroke of the bell can be reduced by shifting the connecting-rod 7 along the rocking lever, 5. Recuperators 50 or other heating-elements are fitted in the conduits 16, 22. The heating-gases are distributed over the length of each heating-chamber by a perforated floor 32 and adjustable damper blocks 33. Instead of the double-action bell shown two single action bells may be used, or alternatively one single action bell may be employed, in which case the conduit 22 is connected permanently to the stack. In the apparatus shown the two chambers 25, 25<a> contain respectively a heating-coil for oil-cracking and a retort or muffle.

Justifying type.-Justifying- mechanism, particularly for photographic apparatus for composing letterpress &c., comprises two groups of relays on which the justification-values for successive lines are set alternately; the justification-values may be determined by means of an automatic divider comprising an arm adapted, when a preliminary setting of the line has been made, to sweep over one or more contacts connected to the relays. The preliminary setting may be made on the perforated strip described in Specification 200,532, [Class 98 (i), Photographic cameras &c.]. The relay-device shown in Fig. 4 comprises two .groups 38, 39 of magnets controlling the engagement of contacts 41 with drums 34, 35 respectivelv, the drums being geared to a rotary member 33 carrying a contact 36 for bridging contacts 32, 37, and contacts 31, 37'. The contacts 31, 32 are connected to contacts 23 closed by the divider arm 20, and the contacts 37, 37<1> are connected to the groups 39, 33 of magnets respectivelv, the groups being thereby alternately connected to the contacts 23 as successive lines are composed. The divider-arm closes one or more of the contacts 23, and one or more of the magnets in the active group are energized, the armatures 40 of these magnets then permitting the associated contacts 41 to engage the drum 34 or 35. The drum controls, in the manner described in Specification 210,355, [Class 98 (i), Photographic cameras &c.], a device 43a for differentially setting means 48 which controls mechanism for punching a justification perforation. The divider arm 20 is pivoted on a slide 1, and passes through a sleeve 19 pivoted on a slide 13, the slide 1 receiving differential displacement corresponding to the set-width of the characters in a line, and the slide 13 receiving unit displacement for each justifying-space in the line. The slides 1, 13 are displaced by magnets 3, 14 associated with the differential stop-mechansim described in Specification 200,127. The slide 13 and contacts 23 are mounted on a plate 26 which normally travels with the slide 1. When the preliminary setting of the line has been effected, the plate 26 is locked by means of a magnet 27, the slide 1 is moved to the end positon, determined by stops 7, 8, and the divider arm sweeps over the contacts 23. To permit lateral adjustment, the sleeve 19 is mounted on a slide 18 normally locked to the slide 13 by means of a magnet 30. The divider arm is provided with spring contact 22.

Title: Detecting mechanism for automatic vending machines
Filed: 1929-01-17
Abstract: 304,246. Sheffield Steel Products, Ltd., (Assignees of Hansen, H. C.). Jan. 17, 1928, [Convention date]. Testing coins.-In coin-freed vending machines of the kind that distinguish between coins having rims and coins without rims, a coin inserted through a shoot 1, Fig. 1, enters a forked head 4 on a counterpoised lever 2 pivoted at 3 and presses apart the curved beaks 14 of a pair of feelers 13, Fig. 3, which are pivoted at 12 outside the head 4 and are held by springs 18 with their beaks 14 projecting through notches 5 in the head into the coin space 19. The springs 18 are secured to the feelers and to screws 17, fixed in brackets 17 attached to the head, the brackets, having pins 16 which pass through slots 15 in the feelers and limit their movement. A rimmed coin is suspended on the feelers and tilts the lever 2 until this meets a stop 20, the ends of the feelers then engaging stops 21, which press them together to release the coin. The coin drops to the left of a partition and passes on to the releasing mechanism for the drawer, turnable door, or the like. If the coin has not got a rim, it is not stopped by the feelers but drops to the right of the partition and passes out of the machine. In a modification, Fig. 5, one feeler 25 is pivoted to the head at 24, the other 33 being pivoted at 32 on the long arm 30 of a bellcrank lever 30, 31, which is itself pivoted at 28 to a bracket 27 and held by a spring 34 against a stop 35. In normal position, the feelers abut against each other at 37 and their beaks 14 are a distance apart at least equal to the width of the coin spaces 19 in the head 4. A rimmed coin entering the space 19 engages the feelers close to the parts 37 and turns them, that the beaks 14 approach each other and engage the rim. When the balance is tilted, the coin is released by the arm 31 engaging a fixed stop. A coin without a rim is not gripped by the feelers and is returned. In a further modification, Figs. 7 and 8, the beaks 14 of two feelers 39 close together by gravity but are held apart by arms 40 engaging depending arms of the feelers. The arms 40 are fixed to a shaft 42 journaled in the head 4 and are held in engaging position by a counterweight 46. The shaft 42 carries another arm 44 forming a bottom to the coin space 19. The weight of an inserted coin depresses the arms 44, 40 allowing the feelers to grip the coin. A coin without a rim rolls along the depressed arm 44 and out of the machine.

Title: Voltage breakdown arc detection system for waveguides
IPC: H03F1/54
Filed: 1964-01-16
Abstract: 1,038,409. Transistor switching circuits; protecting valve circuits. RAYTHEON CO. Jan. 16, 1964 [Feb. 7, 1963], No. 2032/64. Headings H3T and H3W. [Also in Division H2] Arcing in a waveguide 20 is detected by determining the difference between the magnitudes of the micro-wave energy on each side of the arc. In Fig. 1 couplers 21, 29 are connected to the output port 17 of a high power amplifier 16, e.g. a klystron or magnetron, and to the load end of the waveguide 20, the couplers housing microwave detectors, e.g. rectifiers, 25, 30 providing respectively negative and positive output signals. These signals are applied to a resistance network such that when the signals are unbalanced due to an arc, a negative voltage signal is applied to the grid 47 of the first section of a double triode 45 biasing that section towards cut-off. The resulting positive voltage appearing at the junction of resistors 53, 54 turns on a thyratron 71 to produce a positive output signal across a resistor 94. Should, however, the detector 25 fail, a positive voltage signal is applied to the grid 47 causing the first section to conduct more heavily so that the other section of the double triode conducts less, resulting in the turning on of a thyratron 80 to produce the output signal across resistor 94. In either case, the output signal turns on a controlled rectifier 90 to provide a negative pulse to the gate and anode circuits of a controlled rectifier 120. The rectifier 120 is turned off, so that the voltage drop across a resistor 124 disappears and a ferrite switch 14, maintained in the " on " condition by this voltage drop, is placed in the "off" condition to cut-off the supply of energy to the amplifier and waveguide. The rectifier 90 remains turned on for a short period until charged capacitors 108, 110 have discharged. The rectifier 90 then turns off and a transistor 101 becomes conducting to recharge these capacitors. The rectifier 120 then turns on, after a cpacitor 115 has discharged, to restore the supply to the amplifier and waveguide. This cycle of operation is repeated should a further arc or arcs occur until the dust, &c. causing the arcing is vaporized. Reference is made to a modified arrangement in which the supply of D.C. power to the amplifier 16 is interrupted when arcing occurs. Should the coupler 21 be arranged on the waveguide, then a probe electrode, Fig. 2 (not shown), is arranged between the coupler and the window 18 of the amplifier, the probe being connected to a detection circuit which provides a signal to operate the switch control circuit shown in Fig. 1 when an arc occurs in the waveguide between the coupler 21 and the amplifier window 18.
