Title: Direct key calling telephone station having binary converting means
Inventor: VACCARO ANGELO
IPC: H04M9/00
Filed: 1967-05-25
Abstract: 1,155,068. Automatic exchange systems. COLUMBIA CONTROLS RESEARCH CORP. 25 May, 1967, No. 24273/67. Heading H4K. In a private inter-communication system employing a large number of push button telephone substations, relay trees located at a central point but individual to each substation receive a coded designation of a wanted party as determined by operation of the pushbuttons at that substation and effect the required connection. In the figure the equipment enclosed by the broken lines 34 is located at a substation while the remaining equipment is located at a central point. To connect to another station the receiver 11 is lifted moving a cradle switch 20 to its dotted line position thus connecting a current supply to the receiver and one of seven keys 22 to 28 is then depressed thus specifying the first digit of the wanted substation number. Isolating diodes 33 connect the keys to three lines 30 to 32 so that they are selectively energized in accordance with a binary coded representation of this digit. At the central point corresponding self-holding relays 30b to 32b are selectively energized. A relay 42 is simultaneously energized through diodes 39 to 41 moving its contacts 42a to 42c to their dotted line position charging a pair of capacitors 46 and 50. When the key is released the relay 42 is de-energized discharging capacitor 46 through a relay 36. Relay 36 which is maintained energized by its holding contacts 36b moves three contacts 30a to 32a of a twoposition switch to their dotted line position. This disconnects the relays 30b to 32b from the lines 30 to 32 and connects three further selfholding relays 30c to 32c to the lines 30 to 32. A second digit key can now be depressed setting these relays in accordance with the binary code representation of the second digit. The six relays 30b to 32b and 30c to 32c have banks of contacts which form a tree and in accordance with the digits received connect a corresponding output terminal (indicated by digits 1 to 77) to its input terminal. A push button 49 is then pressed sending a D.C. ringing signal to the called station, i.e. to its bell 21. Corresponding output terminals of all relay trees are connected together. An additional connection which connects permanently between a different one of the output terminals (1 as shown) and the input terminal for each substation determines which station responds. As each digit key is released capacitor 50 discharges, enabling a relay 51. If the called station is busy a positive potential is received over a contact 51a to maintain this relay energized. A busy signal oscillator 52 is connected to the calling party over a contact 51b. A contact 42c of the relay 42 is opened while any key is depressed preventing listening in.

Abstract: 761,457. Ejection seats for aircraft. MARTIN, J., and MARTIN-BAKER CO., Ltd. Sept. 3, 1954 [Sept. 4, 1953], No, 24492/53. Class 4. Mechanism for normally holding or locking an ejection seat in an aircraft and for releasing the seat therefrom when an ejection gun is fired comprises a spring loaded locking plunger 6, having a coned end 8, mounted for axial movement in a bore in the top beam 5 of the seat. This beam is extended by side beams 4 which carry rollers engaging channel section guide rails 2 secured to the aircraft structure and to a gun barrel 1. A breech 9 is secured to a ram (not shown) sliding within the barrel 1 when the gun is fired and it carries on its outer surface a sleeve 10 having an annular groove 11 matching the coned end 8 of the plunger 6. With the parts in the relative positions shown in the drawing the plunger 6 passes through a bore 3a in an upper part 3 of the barrel 1 whereby the seat frame is locked to the fixed guide rails 2. Firing of the gun will cause initial upward movement of the breech 9 and sleeve 10 until a face 12 thereon engages a face 13 on the beam 5. Such movement will cause the lower inclined face of the groove 11 to act on the cored end 8 and force it into the bore 3a. Further upward movement will cause the bore 3a to act on the end 8 and force the plunger wholly within the bore in the beam 5 thereby completely freeing the seat frome from restraint to movement up the fixed rails.

Abstract: 332,771. Warwick, A., Taylor, J. A. A., and Holmes, H. C. Aug. 10, 1929. Selective signalling systems. -A system for distributing electrical signals, such as wireless programmes, over lines from a main station to a number of receivers comprises main-station indicating-apparatus which consists of a signal device operated by action at any one of the receivers and identifying means adapted to become operative by action at the main station. The signals may be distributed at high- or low-frequency. Faults at receivers may thus be reported to the main station. In the system shown in Fig. 1, programmes are distributed to stations A1 - - A3 over a line f connected to a wireless receiver or other lowfrequency source a represented by transformer b and situated at the distributing centre at which is located indicating and identifying apparatus B. When a. subscriber at one of the stations inserts plug p into sockets p2, a metallic circuit is completed over transformers s, b, switch j normally in engagement with j<1>, relay i and battery e. The circuit of bell m is closed and the operator throws switch j to connect up an ampere meter k, galvanometer or the like. The signalling circuits of the various stations are of different resistances so that the meter gives an indication of the calling station. As shown. resistances r1, r2, are inserted in the circuits at stations A2, A3. The system shown in Fig. 2 comprises groups of distributing lines fl - - f4 and F1 - - F4 connected by lines v, y, V, Y, to output transformers at the distribution station, condensers c1 - c4, C1 - C4 being interposed in one of each pair of distributing lines. The apparatus B is connected directly to line v, V, and by switches t, T to lines x, X, which are connected by switches u1 - -u4, U1 - - U4 to a conductor of each of the distributing lines which have a number of stations such as A1 - - A3, Fig. 1. The switches t, T, u1 - - u4, U1 - - U4 are normally closed and when the bell at B is rung, the operator manipulates switches t, T to discover which of the groups contains the calling station and then manipulates the switches u1 - - u4, U1 - - U4 to discover the calling distributing line, after which, by throwing in the meter at B, she can ascertain which station is calling.

Abstract: 236,784. Kneppers, J. M. Oct. 20, 1924. Thermostats.-In an apparatus for regulating the temperature of steam-heated boiling-vessels, drying-rooms, &c., by controlling the supply of steam, the supply pipe 1 is provided with a valve 3 which, by means of an adjustable stop 8 cooperating with a lever 4, can be adjusted by hand with the aid of two indicating lamps 14, 15 so as to give approximately the necessary steam supply, and is thereafter automatically adjusted, when any undue fall in temperature occurs, by means of a thermostat 12 operating in conjunction with an electromagnet 5<1> and armature 5 to further open the valve, one indicating lamp 14 being brought into circuit when this minimum limit of temperature is reached, and the second indicating lamp 15 being illuminated when the temperature reaches a maximum limit. The lamp 14 is arranged in parallel with the electromagnet 5<1> and is associated with the minimum contact b of the thermostat, while the lamp 15 is associated with the maximum contact c, and the third contact a is connected through the main switch 17 with one of the electric supply leads. Normally the steam pressure in the pipe 1 closes the valve 3 to the extent permitted by the stop 8, which is adjusted bv hand to give a continuous supply of steam such that neither lamp 14 or 15 is illuminated. If the steam pressure and consequently the temperature falls, the electric circuit is completed at the contacts a, b of the thermostat, the lamp 14 is illuminated, and the electromagnet 5<1> is energized to further open the valve 3. As the temperature rises, the circuit is broken and the lever 4 returns to its position against the stop 8, thus reducing the steam supply to normal again; while any continued rise in temperature is indicated by the lamp 15, denoting that a new adjustment of the stop 8 is necessary.

Title: Improvements in or relating to adhesive applying machines
IPC: B65B7/08
Filed: 1953-09-10
Abstract: An adhesive-applying machine comprises a nozzle, feeding means arranged to <PICT:0747574/III/1> feed successive workpieces therepast, and extruding means arranged to extrude thermoplastic adhesive, supplied to the machine in rod form, from the nozzle on to the workpieces, the machine being so arranged that the extruding means is normally inoperative but is automatically set into operation as a result of a workpiece being brought adjacent the nozzle, and, when so set into operation, the rod is fed forward into the machine and molten adhesive is extruded from the nozzle.  The feeding operation may begin only after a portion of the workpiece has been fed past the nozzle, and may end before it has been fed completely past it.  As shown, filled paper bags B are placed on a conveyer belt 16 which carries them from right to left through the machine.  The top of the bag is trimmed by a pair of cutting discs and folded over upon itself by a folder plate to form a flap, which is firmly pressed together on passing between rolls 79 and 82.  The bag B then engages and displaces a hump 166 on an extension 164 of a lever 160, pivoted at 160, operating a switch 154 which causes a solenoid 142 to be energized, causing clockwise movement of an arm 138 which rotates, through a pawl 140, a ratchet roll 124, the amount of movement being regulatable by an eccentric stop 152.  A rod 106 of thermoplastic adhesive, passing between the ratchet roll 124 and a roller 122 pivoted on a spring-biased lever 128, is thus fed forward a predetermined distance into an electrically-heated nozzle 90, causing a quantity of molten adhesive to be discharged through the orifice 102 on to the flap F, which is held against the nozzle by a frusto-conical roller 172, and is then pressed down against the remainder of the bag by a belt 188.
