Title: Improvements relating to electrically operated horns
IPC: G08B3/10
Filed: 1934-12-13
Abstract: 448,786. Audible signalling-apparatus. LUCAS, Ltd., J., and HARRIS, T. A., Great King Street, Birmingham. Dec. 13, 1934, No. 35787. [Class 118 (ii)] A circuit fo: enabling one o: more horns to be sounded loudly o: softly comprises a two-position hand switch and an elec tromagnetically operated switch which normally short - circuits a resistance, the elec tromagnetically operated switch being operated to switch the resistance into the horn circuit when the hand switch is operated to the soft position. The electromagnetically operated switch has a slight delay to allow the full current to pass initially to the horn mechanism. As shown in Fig. 1, when the hand switch a is moved to make contacts l the current passes to the horns over contacts d, e, but when contacts s are closed relay g opens contacts d, e and the resistance c is included in the horn circuit. In the embodiment shown in Fig. 4, the horn circuit is always closed by magnet armature j. When the loud contacts l are operated, winding i is energized and armature j makes contacts m, k to close the horn circuit. When the soft contacts s are closed, however, winding g attracts armature so that contacts m, k are closed and contacts d, e opened to bring resistance c into circuit.

Abstract: <PICT:0909474/III/1> <PICT:0909474/III/2> <PICT:0909474/III/3> <PICT:0909474/III/4> Apparatus for spraying an electrostatically-charged fine mist of coating material on to an object comprises atomizing means including an atomizing zone from which a spray of the coating material emanates, surface means for contacting a film or layer of the liquid coating material, emanating from the atomizing zone, means for imparting electrical or mechanical vibration to the liquid coating material contacting such surface to pre-condition the same, and means for establishing an electrostatic field between the atomizing means and the object for charging the atomized liquid coating material and deposit it on the object.  As shown in Figs. 1 and 1A, coating material is supplied from a conduit 46 to a conduit 40, and emerges through slits 128 into the bore 118 of a hollow spindle 100.  The spindle 100 is rotated by means of a hollow shaft 70, of insulating material, driven, through belt 26 and pulleys 24 and 28, by a motor 18.  Tin bearings 102, 104 of the shaft 70 are supported in a sleeve 112 clamped to an outer tube 82.  An inner sheat 86 also surrounds the shaft 70, and primary air, supplied from a conduit 62, passes between these two members, and sprays the coating material over the bristles 126 of a brush-like member 124. The material then passed through openings 120 and 123, into the space 146 between a metal disc 140, which is rotated with the sleeve 100, and a stationary, insulating disc 144.  Secondary air, supplied through the conduit 66, passing through the device and between the sleeves 82 and 84, mixes with the coating material as it enters the space 146.  A metal annulus 148 is attached to the disc 144 on the side remote from the disc 140, the parts 140, and 148 being charged to a high negative potential by a power unit 168 and an alternating potential difference of ultrasonic frequency being applied between them by an oscillator (not shown) and impedance-matching transformer I.  In the apparatus shown in Fig. 5, coating material and a motive agent are delivered by the nozzle 202 to a pan P having a knife edge 210, from which the coating material is atomized.  The pan P is charged to a high negative potential by a power source R.  A barium titanate or other suitable crystal C is secured to the pan P and is coupled by a transformer T to an oscillator O which causes it and the pan to oscillate at ultrasonic frequency.  In the apparatus of Fig. 7, coating material and a motive agent, such as air, are sprayed from a nozzle 306 on to a rotating member 316, and the coating material is atomized from the edge 324.  A piezo-electric crystal C is mounted between the member 316 and an insulated slip-ring 312, and is caused to vibrate by an oscillator O; the apparatus is charged to a high negative potential by a power unit R.  Oscillations may also be produced by magnetostrictive, electrodynamic, fluid- or hydro-dynamic systems.

A data-handling arrangement, for accessing a data store including words arranged in pages arranged in segments, operates in accordance with whether page and segment portions of an address satisfy a predetermined requirement. In a multiprogrammed computer, a data store contains 64-word pages in 64-page segments which are in 64-segment zones. Besides data, the store contains a zone table pointer word, a one-page zone table, a 64-page segment table and a 4096-page page table. A data word can be accessed using a virtual address with zone segment, page and word portions by concatenating the zone table pointer word with the zone portion to address a word in the zone table, this word being concatenated with the segment portion to address a word in the segment table, this word being concateanated with the page portion to address a word in the page table, this word being concatenated with the word portion to address the required data word. However, the use made of the pointer word and the various tables is reduced using an associative store holding virtual address parts of the three forms:  (1) zone, segment, page  (2) ones, zone, segment  (3) ones, ones, zone  each form being accompanied by the corresponding table entry. The virtual address of the desired data word is inserted into a shift register and an associative match tried for with the above forms in turn until a match is found, the shift register being shifted to the right (with insertion of ones into the left end vacated positions) after associative interrogation for a given form before trying the next. If no match is found, the data word is obtained using the tables &c, as above. If a match is found, the corresponding table entry from the associative store is concatenated with the virtual address portion next to those used in the associative interrogation which gave match (e.g. the page portion if the matched entry was of form (2)) to address either the data word or a table entry. In the latter case, the word from the table is concatenated with the next portion from the virtual address to address either the data word or a table entry, and so on. Successive virtual address portions are presented for concatenation from the same portion of the shift register, by using repeated left shift, the left shift occurring in response to output of each table word from the data store, the first such word retrieved being also inserted into the associative store together with the corresponding portions of the virtual address from the shift register. As a modification, the associative store could also hold complete virtual addresses (on which a match is attempted first) and the corresponding data words.
