Title: Improvements in or relating to terminal switching arrangements for telephone cables
IPC: H04B3/20
Filed: 1930-06-26
Abstract: 353,211. Two-way terminal equipment. STANDARD TELEPHONES & CABLES, Ltd., THOMAS, P. R., and GROVE, S. H., Columbia House, Aldwych, London. June 26, 1930, No. 19469. [Class 40 (iv).] In systems in which a cable is associated with the two branches of a four-wire circuit over back and front contacts of a relay, the flow of excessive current through the receiving amplifier when the cable is switched over to the receiving branch is prevented by short-circuiting the transmitting branch at this time or by paralyzing the amplifier. In the first arrangement, Fig. 1, the cable C is normally connected to the receiving branch R over front contacts of relay P. When speech arrives over the transmitting branch T, relay M operates and energizes N releasing P. Relay N maintains the circuit of P open during momentary pauses in transmission. When current in branch T ceases, a slow-to-oporate relay O energizes shortly before N drops back so that the transmitting branch is short-circuited when P energizes. In the second arrangement, currents in branch T pass to an amplifier-detector AD1 having two output circuits, one operating relay S to switch over the cable to branch T and the other paralyzing amplifier Al. When current in branch T ceases the charge on condenser c maintains amplifier A1 paralyzed until after relay S has released. During reception the branch T is short-circuited by relay Y and a second (opposing) winding of relay S may also be energized to ensure that S will not operate.

Title: Improvements in and relating to rotary fluid-control valves
Inventor: LUNKEN EDMUND PATTISON
IPC: F16K5/20
Filed: 1962-05-21
Abstract: 1,008,878. Valves. LUNKENHEIMER CO. May 21, 1962, No. 19499/62. Heading F2V. A rotary spherical valve has a body of such material as stainless steel, bronze or carbon steel embodying two square-cornered recesses 22, Fig. 9, housing annular seating-rings 21 of yieldable synthetic material; the rear face 24 of each ring is tapered so as to be normally spaced from the adjacent wall of the recess. Each ring has a curved surface to engage the stainless steel or bronze spherical closure member 16, the radius of which surface is larger than that of the member 16; the centre of curvature of each ring is eccentric to the member 16 and lies on the far side of the centre of the member 16 as shown. In use, the rings 21 deform to provide a greater contact area whereby the unit contact pressure remains constant or increases over a wide range of fluid pressures. The member 16 has a flat top and bottom surface 27, 28 with a rectangular opening 33 passing from the former to the fluid bore 30, Fig. 2, therethrough, the opening loosely receiving the stem 17 of a carbon steel operating handle 18. The stem 17 is rotatable in a bonnet 20 and incorporates a stop 52 that co-operates with arms on a stem plate 47 to define the open and closed positions of the valve. The valve is assembled by first positioning the seating rings 21 and then lowering the member 16 therebetween through the bonnet opening 13 with its smaller dimension 12 across the flats 27, 28, between the seating rings; the main part 54 of the handle 18 is inserted in the opening 33 and manipulated to correctly dispose the member 16 with its larger diameter between the rings and so to pre-load the rings 21 since this diameter is greater than the distance between the rings. The bonnet and stem are then assembled. The valve is readily dismantled and re-assembled so facilitating renewal of the seating rings, for example. The degree of pre-loading is variable and depends upon the seat material and service conditions.

Filed: 1919-08-08
Abstract: 154,283. British United Shoe Machinery Co., (United Shoe Machinery Corporation). Aug. 8, 1919. Periodic.-In clutch and brake mechanism for use with presses for cutting out parts of boots and shoes, a rod 52 connected directly to the clutch lever 22 and by a lever 50 to a brake-operating rod 38 is actuated by a lever 56 moved in one direction to engage the clutch and release the brake for starting by a spring 66 and in the opposite direction to stop the machine by a ratchet-like camwheel 60 secured on a spindle 68 to which is secured a ratchet-wheel 80 adapted to be rotated by a pawl 88 on an arm 86 operated by the treadle 96 and also by a pawl 116 on a bracket 114 secured to one of several rods 8 moving with the platen, which is operated from the shaft 16 by eccentrics. The treadle is connected to the arm 86 by an adjustable link 100 carrying adjustable stop-nuts 108, 112 for engaging a lug 110 on the frame so to limit the stroke of the pawl 88 that pressure on the treadle brings a recess 62 in the cam 60 under a roller 58 on the lever 56, so that the rod 52 is actuated for starting. The platen is thus lowered and on rising, the pawl 116 rotates the ratchet-wheel 80 another step and a lug 64 on the cam 60 raises the lever 56 and stops the machine. The brake rod 38 is spring connected to a lever 34, which is pivoted on one end of the brake band 26 and is connected by a link 36 to the other end. The brake band is secured to a shoe 32 which is anchored by a link 28 to a fixed point 30. The brake drum 24 is mounted eccentrically on the shaft 16, so that the brake action automatically increases as the platen nears the top of its stroke. To prevent accidental rotation of the ratchet-wheel 80, it is normally locked by a roller 122 carried in a ratchet-wheel 82 and engaging with an incline 120 on the wheel 80 and with an adjustable stationary sleeve 72 surrounding the shaft 68. Springs 124 connecting the wheels 80, 82 maintain the roller 122 normally so placed that forward motion of the wheel 80 is prevented. The pawls 88, 116 first move forward the wheel 82, so as to release the hold of the roller 122, and then rotate the wheel 80.

Filed: 1973-04-27
Abstract: 1458671 Injection moulding control LUCAS ELECTRICAL CO Ltd 3 April 1974 [27 April 1973] 20021/73 Heading B5A The pressure applied to material to effect injection into a die cavity 14 is monitored and is compared with a predetermined value corresponding to the maximum pressure required to be applied to the material and when the predetermined value is reached the pressure is decreased. The decreased pressure is preferably sufficient to permit some flow of material into the cavity to compensate for shrinkage. A relief or reducing valve 19 controls the oil pressure applied to a ram 12 from a pump 16 according to the current supplied to the valve 19 by a current source. A transducer 22 feeds to a comparator 23 a signal proportional to the pressure in line 15. The comparator is also fed with a predetermined constant input signal corresponding to the maximum pressure required to completely fill the cavity 14. When the signal from the transducer 22 equals the constant input signal an output is fed to the source 21 to switch it to its second operation condition. The time taken to fill the cavity 14 is measured by a timer 28 and compared with the preferred filling time, and a flow control valve 18 is adjusted accordingly if necessary. If the pressure applied to the injection material fails to reach the predetermined valve after a predetermined time, an alarm will be operated. Modification.-Instead of being electrically regulated, the pressure setting of the valve 19 could be regulated by fluid pressure in a pilot line connected to the valve 19 and provided with high and low pressure inputs.
