A check signal is returned at each step of an electromagnetically operatedmechanical counter. The digit wheel a-j of one of several counters 3 which is to be stepped is selected by potential over a corresponding digit diode 10 and a counter lead 24. Input pulses at 27 combine with potential on lead 28 to set a bi-stable device 25 to state b, whereupon monostable 23 pulses NAND gate 21 to cause transistor 20 to pulse magnet 4 to advance the counter wheel 31. Associated with the wheel 31 is a wiper 30 which passes over a contact 32 momentarily earthing point 35 and resetting bi-stable 25 as a check that the pulse has been counted. If the wiper 30 fails to move the bi-stable 25 remains in state b and a lamp 37 and horn 36 are operated. In a modification, Fig. 4, operating the counter 100 causes energization of relay 105 and opening of contacts 102. A check signal through 107 recloses the contacts.

Filed: 1949-08-23
Abstract: 665,525. Conveyers. HAPMAN, H. W. Aug. 23, 1949. [Sept. 4, 1948] No. 21848/49. Class 78 (i). A flight conveyer has an endless travelling structure consisting of a plurality of cables connected together end to end by couplings, a multiplicity of flights loosely and slidably mounted on said cables, and helical springs mounted on said cables between the flights to space the latter. In one form in which the flights sweep the interior of a closely fitting conduit of circular section the cables 13 are secured at each end in a clevis 17 by means of molten lead 18, each clevis including two parallel arms 19 which embrace a lug 25 or 26 of a coupling 14, lugs 25 and 26 being in planes at right angles to one another. Pins 21 pass through alined holes in the arms 19 and lugs 25, 26 which holes are larger than the pin to give a loose fit. The body of the coupling is a disc 24 provided with a brass rim 38 when used for conveying explosive chemicals. A wiping device for cleaning the conduit tube 11 consists of four quadrants 36 of rubber or the like, Fig. 2, bolted adjustably so that wear can be taken up by means of bolts 32 passing through holes in a ring 34, slots in the quadrants, and screwed holes in the body 24 of the coupling. The flights consist of discs 40 of rubber having dished sides to which metal annular plates 44 are bonded. Cups 47 fit in the central hole of each annular plate to receive the ends of springs 55 of rectangular section wire which encase the cables 13, and also the ends of sleeves 56 of rubber which protect the springs and cables. Both springs and sleeves are compressed somewhat during assembly on the cables. The end flights of each cable are placed with one cup 47 receiving the end of a clevis 17, the clevises and connections to the couplings 14 being protected by rubber sleeves 52 the ends of which are secured by spring clips 53, 54. All the remaining exposed parts are plated with erosion resisting material. In a modification for use with coarse, hot material such as char the flights are of solid metal with counterbores to receive the ends of springs 55 which are compressed almost fully, all the rubber parts being omitted. This modification conveys material only on a straight path when the springs do not open as when traversing a bend. Fig. 6 shows a feed hopper 77 and a discharge hopper 78 for conveying along the conduit 60, hopper 78 being in an end casing 61 housing a deep grooved pulley 63, around which the flights pass and which is driven, so as to engage the peripheries of the flights. A similar pulley 64 in a housing 62 is provided with tensioning means.

[Class 14 (i)] The apparatus for carbonating water and other beverages described in the parent Specification is modified in that the mixing chamber H is disposed at the upper end of the reservoir A, being connected to the gas inlet E by a pipe F with nozzle G. Water is delivered to the mixing chamber by way of orifices N<1> and N<2>, in a conical member M, and a ring L, the orifices N<2> being inclined to impart a swirling motion to the water. In use, the reservoir A and gas chamber B are filled with water, air being vented by a valve S. The cock on the discharge pipe V and the gas supply valve on the pipe T are then opened, and water is discharged from chamber B and gas accumulates above the water in reservoir A. When the cock on pipe Y is closed, pressures equalize in reservoir A and chamber B, and the water and gas non- return valves P and U close. Whenever carbonated water is withdrawn from reservoir A, the valves P and U admit water and gas into the mixing chamber H in countercurrent. the carbonated water passing by apertures H<1> into the reservoir A.

Abstract: 499,893. Mercury switches. GLATZ, P. A. Aug. 10, 1937, Nos. 22042 and 22043. Convention dates, Aug. 15, 1936 and Jan. 9, 1937. [Class 38 (v)] [Also in Group XVI] In a sheet-feeding machine the raising of the feed pile 5 is controlled by means of a feeler lever 2 fitted with a roller 4 which rests on the pile and is fitted with an adjustable counterweight 3, the lever 2 serving to actuate a tiltable mercury switch 1 for controlling the energization of electromagnets 6 adapted to throw a pawl 7 into and out of engagement with a ratchet 9. As shown in Fig. 1, the switch 1 closes the circuit 19 of an electromagnet 22 which withdraws an armature 25 and so keeps the ratchet 7 out of action As the pile diminishes the lever 2 moves counterclockwise and the switch is caused to move similarly by the action of the side 16 of a recess in the lever on a pin 17 carried by the switch. The circuit 19 is thus broken and the circuit 18 closed energizing an electromagnet 23 and moving the armature 25 so as to put the pawl 7 into action to raise the table. The electromagnet 23 may be replaced by a spring 15 which projects the armature 25 when the circuit 19 is broken. In a modification, Fig. 2, the lever 2 is fitted with two screwadjustable counterweights 28, 28a for coarse or fine adjustment, and similar weights 31, 32 adjustable on screws are provided for altering the tilting movement of the lever 2 or the position of its centre of gravity, and similar weights 29, 30 are provided for the tiltable switch 1. The screws on which the weights are adjustable are preferably arranged perpendicular to the pivots of the lever 2 and switch 1 respectively.
