Title: Improvements in or relating to pin-fin assemblies for use in heat exchangers or other light weight wire structures
IPC: F28F3/02
Filed: 1954-04-30
Abstract: 759,958. Making heat-exchangers and structural elements. GIER, J. R. April 30, 1954, No. 12640/54. Class 83 (2). [Also in Group XIII] A method of forming a structural element, in particular a heat exchanger, comprises flattening a wire at intervals along its length to form plain portions 10 alternating with flattened or ligament portions 11, Figs. 1 and 2, and then bending the wire to the sinuous shape shown in Fig. 4 and afterwards subjecting the wire to a further deformation to the shape shown in Fig. 5. The ligament portions 11 are then bonded to heat exchange surfaces, e.g. plates 21, Fig. 7, or tubes, and the portions 10 extend from these surfaces as pin-fins. Adjacent ligament portions 11 may be angularly offset as shown in Fig. 15, so that when the wire is bent a double row of pin-fins is formed (Fig. 16). The wires may be of stainless steel in which case plain steel strips 41, Fig. 11, are resistance welded to the ligaments 11, the strips 41 being afterwards brazed to the heat exchange surfaces. Alternatively (Fig. 12) composite strips of stainless steel 52 and plain steel 53 are welded to the ligaments 11 with the plain steel surfaces 53 outermost, these latter surfaces being afterwards brazed to the heat exchange surfaces 54. The pin-fins may be threaded or grooved (Fig. 21, not shown) and may be of aerofoil crosssection.

Title: Improvements in or relating to signalling devices for use in connection with telephone or like systems
IPC: H04Q3/00
Filed: 1921-05-03
Abstract: 164,313. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Erickson, J.). June 1, 1920, [Convention date]. Three-position indicators.-The line and cutoff relays of a telephone line operate a three-position indicator to show whether the line is idle or engaged in an outgoing or incoming call. The indicator 24 is operated by the armature 6 of the cut-off relay. If the tine relay is first energized, as in the case of an outgoing call, its armature 5 lifts a pivoted stop 19 out of the path of a projection 7 on the armature 6, so that the subsequent energization of the cut-off relay causes it to attract its armature to its full extent, closing its front contacts and moving the target of the indicator into full view in an aperture 23; but if the line relay is not energized, as in the case of an incoming call, the cut-off relay attracts its armature only half-way, merely opening its back contacts and moving the target 24 into half-view. The line and cut-off relays are mounted one above the other behind the plate 21, and are fitted with a cover having a window to display the indicator.

Filed: 1947-05-12
Abstract: 651,779. Road-traffic signals on vehicles. TURK, W. F. May 12, 1947, No. 12722. [Class 118 (ii)] In a traffic warning signalling device for vehicles wherein the indicator is projected longitudinally from a casing 10 by means of a solenoid 14 and returned to the concealed position by a spring 16, the solenoid 14, when energized, attracts the core 15 which slides in guide tube 13 and causes the indicator 12, to which it is attached by non-magnetic member 15a, to be projected into the visible position shown dotted. A pin 13a, fixed to the core 15 and moving along slots 13b in the guide tube 13, compresses spring 16 between plates 17, 17 and the indicator is thereby restored when the solenoid is de-energized. A resilient buffer 18 is mounted on the inner end of casing 10. Contact 38 on the movable plate 17 engages fixed contact 39 when the indicator is operated and causes a lamp to light on a switchboard mounted adjacent to the driver of the vehicle. Alternatively, an audible signal may be given. An ammeter 30 and lamp 33 (Fig. 7, not shown) show whether the indicator solenoid is in or out of circuit. The indicator arrow is fitted with luminous reflectors 19 which may be replaced by lamps. In Fig. 3 (not shown), lamps 23 are provided within the casing to illuminate the indicator when operated. Figs. 8-13 inclusive (not shown) are rear views of a road vehicle, each displaying a '' left," " right," or " stop'' signal according to the invention. The indicators are in individual casings but two or more may be mounted in a further, common casing. Casings with an indicator each end are illustrated in Figs. 14-17 inclusive (not shown).

Title: Improvements in Telephone Systems.
IPC: H04M5/08
Filed: 1916-09-09
Abstract: 109,640. Western Electric Co., and Reinke, A. E. Sept 9, 1916. Exchange systems.-In systems wherein the telephone set of a B-operator is automatically connected, if she is idle, to the toll-line circuit when the A-operator at the other end calls, a short tone signal indicates to both operators that they are in telephonic connexion. The Figure shows a toll line 112 with its line relay 100, line lamp 101, jack 117, and toll relay TR3 (1), together with the toll relays of four other lines. When an A-operator calls, the line relay 100 closes circuits through its retaining- winding, the line lamp 101, and the toll relay TR3 (1). If the operator is free, the relay TR3 (1) is energized and (1) completes circuits for the control relays 102, 103, (2) energizes blocking-relays 110, 111 which short-circuit the toll relays of all the other lines, and (3) opens the earth connexion to the right-hand armatures of all the relays to the right of it, thus preventing their effective operation in the event of calls being made simultaneously over two or more toll lines. The control relay 103 connects the B-operator's telephone set 105 to the toll line. The control relay 102 (1) connects the line lamp 101 to a flashing interrupter so that the operator can identify the line to which she is connected, (2) connects the retaining-winding of the line relay 100 to the release key 104, and (3) closes a circuit for the relays 106, 107 which operate in such a way that the relay 106 connects the tone generator 108 for a short time to the toll-line circuit, thus signalling both operators. A relay 112 is de-energized when the operator withdraws a plug 113 on leaving her position, thus preventing the operation of the control relays 102, 103. The operator can break down any existing connexion by depressing a key 114, and can render the position busy by depressing a key 118 or any order-wire key 115, in each case energizing the blocking-relays 110, 111.

Filed: 1927-05-12
Abstract: 281,220. Dayton Scale, Co., (Assignees of Bryce, J. W.). Nov. 26, 1926, [Convention date]. Pendulum-weight apparatus.-In a weighing- scale provided with a pendulum load-balancing mechanism, the pendulum weight is carried by a pivoted structure which is balanced about its pivot for all weighing positions whereby the point of application of the load-balancing moment always coincides with the centre of mass of the pendulum weight. In the form shown in the Figure, the draw rod 25 from the platform levers is connected to a scale beam 27 pivoted on knifeedges 31. The beam carries a zero-adjusting weight 46 and is coupled to a dash-pot 68. A flexible tape 44 connected to one end of the beam is secured successively to sectors 55, 61, 61<1>, 56 forming parts of structures 59, 80, 60 mounted on pivots 53, 62, 54. The structures are all in neutral equilibrium and the sectors are of circular formation with the exception of the sector 55 which is of varying radius to give an equallydivided indicating dial. Pendulum weights 51, 52 carrying radially-directed adjusting screws 75 are rigidly secured to the structures 69, 60. By adjusting the screws 75 each pendulum may be made to balance one half the load when the scale is level. In the unloaded position of the scale, the pendulums are inclined as shown, and with this arrangement if the scale is out of level the consequential errors introduced into the pendulum and lever systems respectively compensate one another. A rack 40 on the structure 80 actuates the indicating pointer. In modified arrangements the pendulums are arranged at different levels and the intermediate structure 80 may be dispensed with. In a further modification, the beam 27 is provided with a counterweight which causes the pendulums to assume a position at the limit of their travel when the scale is unloaded. A load placed on the platform then acts against the counterweight and the pendulums descend to restore equilibrium.

Abstract: 142,318. British Thomson - Houston Co., (General Electric Co.). May 22, 1919. Regulating; indicating position of internal parts; alarms.- Undue deformation or displacement of a turbine rotor causes the operation of devices for stopping the turbine and sounding an audible alarm. Wires 22 of electric circuits controlling the emergency stop gear and an audible alarm are led to positions 25, 26, where they are covered by insulating and protecting caps. If the rotor, contacting with any of the caps, destroys it, an electric circuit is closed through the turbine casing, and a self-holding relay 32 is energized. This closes the circuit of a bell 41 and the circuit of a coil 13, which releases the emergency stop-gear. It may also close the circuit 48 of a device for operating the main switch of an electric generator driven by the turbine. Fig. 2 shows one of the terminals of the wires 22. The metal cap 18 protects it from corrosion or the accumulation of moisture &c., and a disk of insulating-material 21 presents a premature short-circuit. A switch 49 may be used to short-circuit the terminals and test the condition of the electrical devices.
