Title: Improvements in and relating to automatic burglar and fire alarms
IPC: H04M11/04
Filed: 1934-10-23
Abstract: 442,565. Fire, police, and like alarm systems. DAVIDSON, F. R., SPENCE, A. G., WOOD, W. J., and MOUNTSTEPHEN, E. R., 35, London Road, Southend-on-Sea. Oct. 23, 1934, No. 30356. [Classes 40 (i) and 40 (ii)] [See also Group XXXIX] In alarm arrangements adapted, on occurrence of a fire, burglary, &c., automatically to set up a telephone connection with a fire, police, &c. station and to transmit a message thereto from a gramophone, an alarm magnet operates trip mechanism which simultaneously starts the gramophone motor and connects the microphone of the alarm apparatus to line, the motor operating mechanism which successively dials the required number, lowers the sound-box or pick-up on to the record, returns the sound-box &c., to the commencement of the record for repetition and then clears the line and disconnects the alarm apparatus therefrom. On initiation of an alarm, magnet 4 releases the counterweighted linkage 6, 10, 11 which withdraws a catch 16 which normally holds down the switch-hook 17 of the alarm instrument. The switch-hook is connected to a vertical bar 23 which operates a cam 26 to close the line contacts 27, 27a. When the link 11 moves downwardly it also moves a pivoted catch 15 away from a stop 2b on the turntable so that motor 2 drives the turntable and also moves rack 28 which is mounted in guides 29 and is connected by link 30 to a second rack 33 which operates the dial. Movement of rack 28 lowers the tone arm 72, Fig. 5, by controlling a cam 36 engaging a pivoted member 41 supporting the arm. The tone arm, in its passage over the record, carries with it an arm 47 on a shaft 48. When the record has been played, cam 49 on shaft 48 allows rack 50 carried by lever 52 to engage a pinion driven by the motor. The rack operates a linkage 55, 57, 58 so that a pin 61, Fig. 6, on 58 engages underneath the tone arm 72 and restores it for re-playing the record. During successive movements of the tone arm across the record, a pawl 77, Figs. 2 and 5, engages projections 78, 89 on a rotary plate 79 carried by a vertical shaft 80, and after the record has been played twice, cam 82 on the shaft operates linkage 73, 74, 75 which releases a counterweighted lever 86 which drops on the switch-hook, so that contacts 27, 27a are opened, and catch 15 stops the turntable.

Abstract: 780,417. Winding yarn. BRITISH NYLON SPINNERS, Ltd. Oct. 12, 1956 [Oct. 27, 1955]; No. 30711/55. Class 120(2) A process for winding yarn on a rotating receiving member mounted on a spindle by means of a ring surrounding said member and a traveller free to rotate around said ring, the ring being mounted in a ring rail for movement axially of the spindle, is characterized in that the initial lengths of yarn are wound in a bunch or bunches separate from the main winding by means of a secondary ring and traveller positioned below the field of traverse of the ring rail and surrounding the receiving member and/or a part of the spindle upon which the receiving member is mounted. In the arrangement shown yarn 1 is led from some processing apparatus (not shown) through a guide 3 positioned above a vertical spindle having a yarn receiving member 5 thereon. The yarn is lead through the main traveller 7 on ring 9 which is reciprocated over a length of the yarn receiving member 5 by a ring rail 11, and then to a secondary traveller 13 on a ring 15 and is positioned on a projection or hook 17. The ring 15 is mounted on a rail 19 which is connected to a treadle (not shown) which serves to determine the height-wise position of the traveller 13. A waste auxiliary tube 21 is fitted loosely around the member 5 and seated on the spindle whorl 23. Initially the yarn is held in engagement with the secondary traveller 13 by means of a trapping ring 25. After the initial windings have been wound on the waste tube 21 the ring 25 is moved upwards and the main winding on the member 5 is commenced. The secondary ring and traveller may also be used to wind a transfer tail on the main receiving member 5 before the main winding starts. It is stated that the invention may also be used in combination with a waste receiving device such as a suction tube &c. Specifications 543,466, 643,625, 780,414, 780,415 and 780,416 are referred to.

Title: Improvements in and relating to contact condensers
IPC: F28B9/00
Filed: 1955-10-28
Abstract: <PICT:0809510/III/1> In apparatus for condensing steam, e.g. from a turbine, by direct contact with water, wherein some of the water withdrawn from the condenser is pumped back to the water inlet of the condenser via the vertical pipes of a heat-exchanger in which the water is cooled by atmospheric air flowing over the outside of the pipes, the heat-exchanger is provided with valves which may be adjusted in such a way that the water flows upwards through all the pipes and drives the air out of the pipe system, or in such a way that the water is quickly discharged from the pipes.  The pipes can be readily filled with water or emptied; and the freezing of the water in the apparatus, when the atmospheric air is below zero and the turbine is not running on a large amount of steam (or is not in operation at all) can easily be avoided.  The heat-exchanger shown in Fig. 2 comprises two groups of ribbed pipes 28, 30 disposed between lower headers 27, 31 and upper header 29.  Water is pumped into the heat-exchanger through pipe 25, while valves 14, 16, 18 are open but valves 13, 15, 17 are closed, so that the water flows up both groups of pipes and displaces air which escapes through valve 18.  After removal of the air, the apparatus is made ready for normal operation by opening valve 13 and closing valves 16, 18.  The water now flows up pipes 28 and down pipes 30, and it then flows via valve 13 and pipe 34 to the nozzle 10 of condenser 9.  Steam from a turbine plant (not shown) flows through pipe 8 into condenser 9, where it is condensed by the water sprayed in through nozzle 10.  The water leaves the condenser through pipe 11; some of it is pumped through pipe 24 to the boiler, and the remainder is pumped to header 27.  The discharge of water from the heat-exchanger is effected by closing valves 13 and 14, and opening valves 15, 16, 18.  If the empty plant has to be set in operation in cold weather, the water that is supplied to the heat-exchanger has to be preheated.  This may be achieved by admission of steam to the condenser through line 32 and valve 33, and circulation of the water from the base of the condenser, by means of pump 26, through pipes 25 and 34 (the heat-exchanger is not in circuit) until the water attains a suitable temperature, whereupon the filling of the heat-exchanger is effected as already described.  The headers of the heat-exchanger may be connected to the vacuum space of the condenser, so that any air entering the system during operation is expelled through the vacuum pump.

Abstract: 871,912. Sonic inspection devices. CANADIAN PATENTS & DEVELOPMENT Ltd. Sept. 10, 1959 [Oct. 3, 1958], No. 30962/59. Class 40(7) [Also in Groups XIX and XL(b) ] A sheet of material is tested for flaws by converting a part of the sound generated by rubbing a brush on its surface into an electric signal and indicating any difference between the amplitude of that signal after frequency-filtering and a predetermined amplitude. Panels 10 Fig. 1 of plywood are conveyed through the testing apparatus by rollers 11 . . . 14 and a brush 21 is rotated by motor 22 and is traversed across the panels. The brush is mounted in a housing having a cover 47 Fig. 3 lined with sound-absorbing felt 49 to insulate microphone 36 from external noise. The microphone output passes to a band-pass filter 39 centred on 8 kc./s. via a photo-electric switch 81. When the filter output departs from a predetermined level, due to the change in acoustic impedance of the panel portion encompassed by the brush by a flaw (e.g. between the plies), solenoid 41 causes plunger 42 to depress lead 46 which marks the plywood surface. To obviate relay 40 operation when the gap between panels reaches the brush housing a photo-cell 81 Fig. 6, to which is directed light from source 80, opens switch 81. To prevent the brush housing dropping between long gaps between panels, a roller 74 on arm 100 of a switch 70 is provided; the switch when operated energizes solenoid 71 the plunger 75 of which causes one end of carriage frame 20 of the brush housing to be forced upward. In another embodiment stationary brush and microphone units are employed each having the apparatus depicted in Fig. 3, Fig. 2 (not shown); in a modification each brush is fixed and reactangular in cross-section, Figs. 4 and 5 (not shown), a high panel feed speed being employed to ensure sufficient sound energy production.
