Title: An electric circuit arrangement including a relay
IPC: H04Q1/18
Filed: 1945-01-22
Abstract: 587,847. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., BARKER, R., and LONG, D. P. Jan. 22, 1945, No. 1703. [Class 40 (iv)] [Also in Groups XXXVII and XXXVIII] A polarised relay TX, which responds only to voltages below a certain value, comprises an upper winding and a lower opposing winding in parallel, one or both windings being biassed by a battery TB or by separate batteries and a rectifier MRA being connected in series with the lower winding. As shown, the wires M, G are connected to tappings along a battery MB and the direction of current for operation is that indicated by the arrow. With the wire M connected to the point A, the relay operates when the potential of G is more positive than that of M by an amount equal to the voltage of the battery TB, there being no current in the lower winding. For greater potential differences, the currents in both windings produce a differential effect. With the wire M connected to the point B, the relay operates when G and M are at the same potential. The relay may be used in an automatic telephone system, for example, of the kind described in Specification 585,495, for controlling the setting of a selector in accordance with that of a twowiper digit switch M1, M2 of which the contacts are slip-multipled to tappings along the battery MB so that the wiper M2 is always one step more positive than M1. The contacts of the wiper G of the selector are grouped together, not necessarily in sequential order and connected to the various tappings. Relay TX operates when the potential encountered by wiper G is such that current flows in the upper winding and not in the lower, and connects up relay T to test for an idle condition over wiper P.

Title: Improvements in or relating to paper stack raising mechanism for printing machines
IPC: B65H1/18
Filed: 1957-01-18
Abstract: 847,826. Feeding sheets. FRANKFURTER MASCHINENBAU AKTIENGESELLSCHAFT VORM. POKORNY & WITTEKIND. Jan. 18, 1957 [Dec. 5, 1956], No. 2011/57. Class 100(1) Mechanism for the automatic adjustment of the height of a stack 6 of paper sheets resting on the stack board of a printing machine comprises a pawl driven ratchet 13 in driving connection with a spindle 17 for raising the stack board, the pawl 7 being pivotally carried on a lever 2 arranged to oscillate continuously during running of the printing machine and being spring loaded in such a manner that it is in a condition of unstable equilibrium in which it is out of engagement with the ratchet, the condition being maintained until, due to a predetermined decrease in the height of the stack 6, means become operative to change the condition and the pawl is caused to engage the ratchet. The lever 2 is pivoted at 3 and has a cam follower 11 whereby the lever is oscillated by a cam 1. The pawl 7 is pivoted on the lever 2 at 15 and has pivoted thereto a bolt 10 surrounded by a compression spring 9, the spring 9 being retained on the bolt 10 by the pawl 7 and an end support 8 on the lever 2. The lever 2 oscillates a stack height detector 5 through a link 4. With the stack 6 at the correct height the detector 5 contacts the stack, thus preventing further pivoting of the lever 2, before the latter has pivoted sufficiently for a fixed stop 12 to engage the pawl 7, and the pawl 7 remains out of engagement with the ratchet 13. When the height of the stack drops a predetermined amount, however, the detector 5 fails to stop movement of the lever 2 before the stop 12 has engaged the pawl 7. The pawl is thus pivoted about the pivot 15 so that the tooth 71 of the pawl can engage a flank 131 of a tooth of the ratchet wheel 13. Clockwise rotation of the lever 2 then causes the stack to be raised, the operation being continued until the stack reaches the required height. After each oscillation of the lever 2, the tooth 71 of the pawl slides along the back of the next tooth of the ratchet wheel 13 and is thus returned to the initial position of unstable equilibrium.

Abstract: 782,376. Sound-protective devices. PARMEKO, Ltd. Jan. 23, 1956 [Jan. 24, 1955], No. 2048/55. Class 13. [Also in Group XXXIX] A loud-speaker of the horn type for use in situations in which excessive noises or explosions might rupture the diaphragm is provided with a valve which permits the passage of sound from the horn but closes if external pressure is excessive, the valve being held closed except when the loud-speaker is in use. The valve V is as described in Specification 462,397, [Group XXXIX], but is normally held closed under the pressure of a spring 13. When the loud-speaker is to be used a solenoid S is energized to permit the valve V to take up the position shown in Fig. 2. While the loudspeaker is in use, if an explosion occurs the external pressure presses the valve against the perforated plate 6a so saving the pressure unit 5 from damage.

[Also in Group II] A dosage device for continuously mixing one liquid with another comprises a pipe capable of regulation for feeding a dosage medium to a pump having a rotary pump housing in which is mounted a paring device connected with a pipe through which the liquid to be mixed with the dosage medium flows under pressure. As described vegetable oil flows under pressure along a pipe 1 and a refining agent to be mixed therewith is introduced through a pipe 2. The refining agent is fed from a pipe 6 containing a regulating valve 5 into a cup 7 and then through a pipe 10 into a rotating housing 3. Rotating. with the housing 3, a member 13 impels the refining agent through passages 14 into the outer part of the pump housing. A disc 4 held stationary within the casing 3 is provided with channels 16 and when the liquid in the pump housing is of suffi- .cient depth its pressure forces it into the channels 16 of the paring disc against the pressure existing in pipe 1. The cup 7 contains a float 8 which operates a valve 12 to prevent air from entering the pipe 10. In Fig. 2, not shown, the refining agent is fed through a device by which means the amount of refining agent supplied per unit time is determined, a quantity meter being provided to give a reading of the dosage.

Filed: 1927-01-27
Abstract: 268,296. Waygood-Otis, Ltd., (Assignees of Jones, B. N.). March 23, 1926, [Convention date]. Applied by springs and weights; block and the like acting on drums; force-transmitting mechanism; electric.-Relates to brakes, comprising friction shoes engaging a drum more particularly multiple-shoe braking mechanism for lifts and the like wherein the shoes are automatically applied by mechanical means and released by an electric or other rotary motor during hoisting. The Brake is released by one or more cams 48, 68 on the releasing motor shaft 47, which is allowed axial travel to balance the movements of the brake shoes. The cams 48, 68 are face cams and engage rollers on the end of pivoted levers 56 connected by adjustable links 67 to levers 36 pivoted on pins 42 carried by the brake frame. The levers 36 carry the brake shoes 35 in openings in the levers on pins 37. Brake applying springs 38 are mounted between a spring seat 27 mounted on the pin 37 and an adjustable spring seat 31 carried by the brake frame. When the motor is energized the cams 48, 68 are rotated to release the brakes a pinion 73 on the motor shaft lifts a dash-pot piston 87 by means of a rack 81 until a buffer spring 88 engages the dashpot cylinder cover and the motor is stopped but maintains the brakes applied as long as it is erergized. On de-energization of the motor the piston drops rotating the motor shaft and allowing the springs 38 to apply the brake shoes. If on releasing the brake one cam engages before the other the motor shaft slides to cause the other cam to engage and both brakes are released simultaneously. If in applying the brake one shoe engages before the other the operating cam thereof recedes from its roller and allows the pressure of the application spring of the other brake to cause the motor shaft to slide and apply this other brake. Brake release stops 105, 108 are provided on the brake levers 36 and engage the brake casing. If one application spring is stronger than the other the motor axle slides and the cam releases the brake with the weaker spring. 'When the stop 105 or 108 engages, the axle slides back again to release the other brake. Considerable clearance is allowed for the motor axle bearings 51, 71 between covers 111 and housing hubs 112. to allow the axial movement. The flow of air into and out of the cylinder 82 of the dash pot piston 87 is controlled by a replaceable ball check valve 90 and a passage 92 fitted with a longitudinally slotted adjusting- screw 93. The brake shoes are maintained concentric with the drum by adjustable springs 100, mounted on the levers 36, which holds the shoe in engagement with adjustable stop 96, also mounted on the lever 36. The upper ends of the levers 56 are in the form of yokes to clear the cams. The whole motor may slide axially.
