Abstract: 121,489. Withers, J. S., (Cox, K. C.). Sept. 18, 1916. Moving-coil relays.-To counterbalance the force due to the harness, an adjustable force is applied at the axis of rotation of the coil, while the tension in the suspension wires is controlled by an adjustable spring. The contacts of the relay are mounted upon a block pivoted to an adjustable slide, and sparking is prevented by using condensers and a resistance or resistances connected acrcss the relay contacts. The force due to the harness wires 12 of a coil 2 is counterbalanced by a thread 15 passing over an adjustable screw or roller 17. The tension in a wire 3, connected to the lower end of the coil 2, is varied by a leaf spring 4 mounted in an adjustable block 7. The fixed contacts 13, 14 of the relay are mounted upon a pivoted block 30 mounted upon an adjustable slide. Sparking at the contacts is prevented by condensers 20, 21 and a resistance 22. The resistance 22 may be replaced by two resistances placed in the leads a<1>, b<1>. The coil 2 is suspended by wires 1 connected to a head as described in Specification 110,374, [Class 40 (iv), Telephones &c.]. Specification 399/14 also is referred to.

Shuttles.-The blade B and heel b of the tongue are formed in separate parts, or in one part, and maintained in normal position by a spring or buffer b<1> as described below, to permit of longitudinal movement of the blade. In the form shown in Fig. 1, a shoulder b<2> on the rear end of the blade fits in the hollow heel b, and the spring b<1> is placed over the blade and is compressed between the shoulder and the reduced front end of the heel, the rear end of which is closed by a screw plug b<3>. Rotation of the blade is prevented by a pin or key b<4> traversing an interior keyway in the heel; or each end of the pin may enter a slot in the heel. In another form, Fig. 8, the spring b<1> is placed in a hollow chamber in the blade, closed by a plug, and the spring is compressed between the plug and a pin b' inserted through the front .end of the hollow heel b and working in slots in the blade. In another form, Fig. 9, the rear end of the blade enters the hollow heel and has a pin b<4> projecting through slots in the heel. The spring b<1> is placed on the exterior of the heel and is compressed between the pin and a collar screwed on the heel. In modifications of the form of Fig. 1, the heel is solid at its rear end and the blade is inserted through the other front end. which is then closed by a screw collar, the collar b<2> and the interior of the heel are made square to prevent rotation, the blade and its hole in the heel are made square for the same purpose, and both collar and blade and the co-operating parts are square. The front of the heel may have a transverse slot so that it can be compressed to take up wear. In a modification of the form of Fig. 9, a rubber buffer is substituted for the spring b<1>. In another form, Fig. 21, the blade and heel are made in one part, the pivot pin a enters slots a<3> in the shuttle, and springs b<1> are compressed in the slots and act on the pin.

Patent GB-508985-A (GB)
Title: Improvements in or relating to automatic telephone selectors
IPC: H01H67/12
Filed: 1938-05-04
Abstract: 508,985. Automatic exchange selectors. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 4, 1938, No. 13301. Convention date, May 5, 1937. [Class 40 (iv)] In a two-co-ordinate selector using a bare wire multiple, the wipers are formed on the ends of flexible steel strip or wire conductors 5 which are secured to a sliding member b and are guided through a right angle by a sliding carriage a so that movement of the member b towards the carriage pushes the wipers into the multiple. The outer ends of the conductors 5 move in slots in forward extensions 25 of the carriage a and are protected by insulating sleeves 6 which engage the multiple wires and form guides for the wipers. The sliding member b is moved first to the left and then to the right by a reversible step-by-step motor d. During the first movement, the conductors 5 form a tractive coupling with the carriage a and the latter follows the movement. The engagement of a pawl 17 with a ratchet 18 prevents the return of the carriage, and therefore the movement of the member b to the right pushes the wipers into the multiple. To restore the selector, impulses are continuously supplied to the motor and the member b is moved to the left to an extreme position, so that the wipers are withdrawn and then the carriage is moved until the pawl 17 passes beyond the ratchet 18. A weak helical spring 16 tending to move the carriage to the right ensures the withdrawal of the wipers. The motor is reversed by the operation of a relay over springs g which are closed when the extreme position is reached and the member b drives the carriage to the normal right-hand position, the pawl 17, which is carried by a leaf spring, passing along the plane under-surface of the ratchet 18. The outer ends of the conductors may be provided with helical springs which tend to push the wipers into the multiple. The conductors may be connected to a terminal distributer 26 by a cord in the usual manner or they may be brought in separate loops directly thereto.

Title: An electrically heated hot-water boiler for domestic and other heating systems
IPC: F24H7/02
Filed: 1962-04-09
Abstract: 981,244. Heat storage hot water boilers. T. BAXTER. April 8, 1963 [April 9, 1962; Jan. 31, 1963], Nos. 13574/62 and 4019/63. Heading F4U. In an electrically heated hot water boiler heat is transferred to a water boiler unit from a heat storage block unit having electric heaters mounted in housings at different locations in the unit, and heat conductance elements are disposed within the block unit and in adjustable connection with the water boiler unit to collect the heat from the block and pass it to the boiler unit, said connections including a control for adjusting the rate of heat transfer to the boiler unit. In Fig. 1, the device comprises a series of interfitting heat storage blocks SB forming a block unit, each of a size such as 24 in. x 24 in. x 5 in. deep, and with corresponding recesses H1 in their upper and lower surfaces such that an electric heater may be inserted into the recess between two blocks. The joints between blocks are lined with heat conducting sheets or rods which transmit heat to a vertical heat conductance tube R. The heat is transferred from this tube R to a hot water boiler HEU by a finned tube F. The rate of heat transfer is controlled by raising or lowering an upper, wider section of tube R by a cable and pulley system operated by a thermostatic device acting on a weight suspended beside the block unit. The unit is surrounded by lagging on all sides. The heat conductance tubes may be replaced by channels through which air can be forced. In Fig. 3, the structure is basically similar except for the top heat-exchange section, and the heat conductance tubes. The tubes 25 are fixed to an upper heat transfer plate and are of tubular interfitting, telescopic construction, the diameter lessening with depth. The heat transfer is controlled by pivoted dampers 30 connected to a link system, the dampers being beneath a water boiler 28. -When fully open said dampers are in connection with the upper and lower surfaces of the heat transfer plate and the boiler respectively, and heat can be conveyed by conduction and radiation. When closed, radiated heat from the transfer plate is reflected from the polished copper surface of the damper. In a modification, electric heaters may be housed in alternate blocks, the other blocks being slightly narrower and of less coarse grain. In another modification, there may be a network of horizontal conducting plates joined by edge flanges to vertical plates and rods, the latter being joined to the top heat transfer plate. Specification 967,835 is referred to.
