Abstract: 949,339. Lubricating. GEO. W. KING Ltd. Dec. 19, 1962 [Nov. 10, 1961], No. 40339/61. Heading F2A. A lubricating apparatus for conveyer chains has a mist lubricator, the nozzles of which supply lubricant to the chain; a solenoidoperated valve which controls the supply of pressure fluid to the lubricator; and a control unit having a spring-loaded member which is actuated by the moving chain so as to operate the solenoid and allow a supply of pressure fluid to the lubricator and to effect a discharge therefrom via the nozzles. In an embodiment, the lubricating apparatus has two units 15, 16, the former serving to lubricate wheel and roller assemblies 12 of a chain 10 and the latter serving to lubricate the connecting pins of the chain. The units 15, 16 are connected by a T-connection 18 to pressurized air, via an air filter 19. The connection 18 communicates, via supply lines 17, with air-pressure regulators 20 ; solenoidoperated valves 21; and mist lubricators 22, having Y-connections 23 carrying tubes 24 with nozzles 25 thereon. The nozzles 25 which lubricate the assemblies 12 are received by apertures in the side walls of a track 11 so as to be disposed one at each side of the chain and the nozzles 25 which lubricate the connecting pins are positioned above the chain. Each solenoid valve 21 is actuated by a control unit 26 or 27, each unit having a lever 28 pivoted at 29 with a plunger 30 mounted thereon. The plunger 30 projects through an aperture 31 in one of the side walls of the track 11 and is engageable by side rollers 14 of the wheel assemblies 12 so as to move the lever against the action of a spring 33 and cause a member 35, carried by the lever 28 to close a switch 36 and actuate the solenoid valve 21 so as to cause spraying to be effected. The movement of the lever 28 is limited by an adjustable stop 34.

Title: Improvements in fire-detection systems
IPC: G08B17/06
Filed: 1962-10-26
Abstract: 964,386. Testing alarm circuits. J. E. LINDBERG. Oct. 26,1962 [Nov. 1, 1961 (2)], No. 40626/62. Heading G1V. [Also in Division G4] A fire detection system comprises a heat sensor 3 having two electrical conductors 4 and 5 spaced apart by a heat sensitive material 6 which is of low electrical conductivity below a critical temperature and is more conductive above this critical temperature, and the heat sensor is connected in a comparator circuit with a first source of potential 9 and a warning device 7 so that heating of the heat sensor by fire causes unbalance in the comparator circuit, and actuates the alarm. According to the invention, in order to test the system the conductor 5 of the heat sensor can be connected temporarily to a second source of potential 20, by means of a switch 12 to heat the sensitive material above the critical temperature so that the warning device in the comparator circuit will be actuated. In carrying out the test with the embodiment shown in Fig. 2, the switch 12 is set in the "test" position so that the wire is heated to above its critical temperature, and then set to the "operate" position. If all parts of the system are acting correctly, the alarm 7 will ring. The alarm is prevented from ringing during the "test" part of the operation by including a blocking condenser 18 in the comparator circuit and operating the resistance bridge from an A.C. power supply. Alternatively the bridge power supply may be D.C., the test power supply A.C. and the condenser replaced by an inductance (Fig. 3 not shown). An embodiment containing no arrangements for preventing the alarm ringing when the switch 12 is in the test position is also described (Fig. 1 not shown). Examples of the heat sensitive material included in the heat sensor are given; these include sodium or potassium nitrate inside a copper tube with an axial copper wire, barium and strontium oxide or heat resistive compounds in bead form separating a pair of wires inside a tubular cable.

In a synchronous selfshifting one-way clutch or brake, wherein an intermediate member 59 is helically movable along splines 57 on one clutch or brake member 54 to engage intermediate member teeth 60 with teeth 42 on the other clutch or brake member 41, the one member 54 is coupled to a rotary shaft or, as shown, a stationary member 45, through a lost - motion positive connection in parallel with a fluid dashpot means 50, the take-up of load after the teeth 60, 42 are fully engaged being cushioned by the dashpot means during relative circumferential, lost-motion taking-up, movement between the members 54, 45. Helical movement of the intermediate member 59 is initiated by a pawl and ratchet mechanism 43, 61 between the members 41, 59. In the one-way brake shown, the lost-motion connection comprises generally radial lugs 64, on the member 54, extending through circumferentially larger slots in a ring 44 fixed to the stationary member 45. The dashpot means 50 comprises one or more sets of co-operating pistons and cylinders respectively connected to the lugs 64 and the ring 44. The cylinders are supplied with oil under pressure through inlets 51. After full engagement of the teeth 60, 42, oil is expelled slowly through orifices in spring-biased valve plungers in the cylinders, bringing the member 41 to rest as the lost motion is completely taken up. On releasing- rotation of the member 41, the cylinders are recharged through ports opened by movement of the valve plungers against their springs. In the one-way clutch of Fig. 9 (not shown), the inlets 51 are connected by pipes to the rotating member of a rotary fluid union. In the one-way brake of Figs. 1-3 (not shown), the lost-motion connection comprises one or more pairs of axially extending, circumferentially widely spaced external and internal teeth respectively of said one brake member and the stationary member, and the dashpot means comprises the one or more circumferential chambers provided between said teeth. The axial ends of these external and internal teeth are respectively bounded by oil pressure inlet, spring-loaded, one-way valves and by exhaust orifices. The dashpot fluid restriction is provided by the external and internal tooth tip clearance. In Figs. 7, 8 (not shown), one or more cylindrical bags of flexible material, e.g. oil-resistant rubber, are provided between the widely spaced external and internal teeth and are supplied with oil under pressure through valves having spring-biased, orificed plungers.

Abstract: 1,076,647. Copying by scanning. XEROX CORPORATION. Oct. 8, 1964 [Nov. 1, 1963], No. 41165/64. Heading H4F. [Also in Division B6] An ink-recording apparatus comprises a reservoir 10 formed with a capillary tube 11 in which a pin 12 is reciprocated in response to an electrical signal. The reservoir is closed by a lid 18 having vent-holes 20 or porous to air. A roller 16 engaging the recording surface 17 holds the tube 11 and surface 17 in fixed spaced relationship. The reservoir may be provided with an ink filler spout at the side. In operation, the ink forms a meniscus at the bottom of the tube 11, with the pin in its uppermost portion as shown. When the pin moves downwards, it carries with it the central part of the meniscus which becomes broken away from the remainder, and deposits it on the surface 17, the pin in its lowermost position being slightly spaced from the surface 17. Thus, with relative movements between the tube 11 and the surface a series of dots are printed on the latter.
