Title: Improvements in Artillery Projectiles.
IPC: F42B12/60
Filed: 1916-04-05
Abstract: 100,255. Soc. Anon. Meccanica Lombarda. April 6, 1915, [Convention date]. Projectiles. - Relates to shells made with a number of bullets in their walls, these bullets being expelled during flight by an explosive charge which is ignited by a time-fuse, the shell being subsequently burst on impact by a high - explosive charge situated within the bullet expelling charge. According to the invention, the two explosive charges S, E, Fig. 2, are contained within concentric casings C, I, which can be attached to the projectile and detached therefrom as a single unit. The charge in the casing I is subdivided by flanges a on the casing C. The wall of the shell is made with recesses arranged in spiral formation around the shell for the reception of bullets p, which may be jacketed and are expanded into annular grooves r to lock them in place; or the bullets have bands expanded into said grooves. The bullets are provided with raised parts fitting into riflings in their recesses, or the bullets are shaped like spiral polyhedra and the recesses correspondingly shaped. The bullets project slightly inside the shell to hold the casing I slightly away from the wall of the shell. The charge E is ignited by a time-fuse T, and the high-explosive charge S is fired by a percussion fuse P. The annular elements of the charge E may be separately enclosed in floss-silk gauze. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which there is no. casing C and no charge E, separate cartridges b, Fig. 8, (cancelled), being used for each bullet, ignition being conveyed from the time-fuse to holes b<1> in these cartridges by an explosive train around the cartridges between the wall of the shell B and the central casing C. This subject-matter does not appear in the Specification as accepted. Projectile fuses.-The percussion pellet m is locked bv spring bolts q, which are moved out of the locking position by the set-back of a ring 0 when the projectile is discharged. The time-fuse T is provided with an annulus g of explosive composition, which communicates with the charge E of the shell through several perforations normally covered by a thin inflammable diaphragm.

Title: Vehicle headlamp circuit
IPC: B60Q1/14
Filed: 1972-02-03
Abstract: 1329948 Vehicle lighting systems GENERAL MOTORS CORP 3 Feb 1972 [8 Feb 1971] 5041/72 Heading H2H A lighting system for a vehicle having headlamps including main beam and dipped beam filaments includes means whereby the headlamp filaments may be energized for any desired length of time independently of the vehicle lighting switch. The headlamps of a vehicle are energizable from a battery 18 by way of transistors 20-26, a dimmer switch 30 and a main lighting switch 38. The switch 38 has connected in parallel therewith a further switch 40 which is operated conjointly with the dimmer switch 30, the operation being that each actuation of the dimmer switch plunger moves the switch blade 36 alternately from contact 28 to contact 32 and vice versa, but the switch 40 is closed only whilst the dimmer switch plunger is depressed. Thus operation of the dimmer switch plunger causes energization either of the main-beam filaments 10, 12 or of the low beam filaments 14, 16 whilst either the high beam or low beam filaments will be energized according to the position of the switch 30 by way of the switch 40 for as long as the dimmer switch plunger is depressed should the main lighting switch be open. Thus the headlamps may be flashed during daylight conditions.

Title: Method for welding high tensile strength steel
Inventor: NAKAI TUNEO
IPC: B23K25/00
Filed: 1970-02-03
Abstract: 1283491 Welding by fusion HITACHI SHIPBUILDING & ENG CO Ltd 3 Feb 1970 5210/70 Heading B3R In arc welding of steel of high tensile strength (greater than 60 kg./mm.<SP>2</SP>), brittleness due to inclusion of upper bainite, in the minute zone in the base metal adjacent the penetration boundary between the weld metal and the base metal heat affected zone, is avoided by the combination of electroslag welding, and high speed liquid cooling of the solidified weld metal and base metal near the molten weld metal, the weld being subsequently tempered. The high speed liquid cooling transforms the structure in said minute zone into a structure comprising martensite and lower bainite or, preferably, into a martensitic structure, these structuresbeing subsequently transformed by the tempering into a structure comprising tempered martensite and tempered lower bainite, or a tempered martensitic structure, respectively. As shown, each of upwardly moved, carbon, melt-retaining shoes 103, conventionally liquid cooled via ducts 111, is cut away at 106, at its trailing end, and has holes 107 over the entire shoe width through which liquid coolant (e.g. water) is ejected for said high speed cooling. The shoe is coated with anti-wear mould paint 115, e.g. a glass type such as silica serving as slag. Contamination of the molten weld metal by upwardly directed steam from the coolant may be prevented by a soft sealing roll, e.g. of asbestos, projecting from the shoe (Fig. 9, not shown), by a suction device disposed below the holes 107 (Fig. 10, not shown), or, as shown, by a curtain of inert gas ejected from holes 108 above the holes 107, said inert ,gas also having a cooling effect. The shoe portion with the holes 107, 108 is attached to the remainder of the shoe by way of low thermal conductivity material. to prevent heating, of the coolant. The coolant from the holes 107 or coolant ejected from separate holes may break the slag covering the solidified weld metal. The inert, gas providing said curtain may be used to break up and blow away the slag, or gas (e.g. air) may be ejected from separate holes for this purpose. Slag removal air jets may surround the holes 107 and guide the coolant. Further, the slag may be removed mechanically.  Reference has been directed by the Comptroller to Specification 1,030,405.

Title: Speech recognition apparatus
IPC: G10L21/00
Filed: 1961-02-13
Abstract: 969, 508. Frequency analysis; photo-electric recognition of speech. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 13,1961 [ Feb. 12, 1960], No. 5267/61. Headings G1A and G1U. A speech recognition system includes means for converting the sound waves into electric signals of different frequencies and for representing the different frequency components of the word and for comparing the waveforms of these signals with reference waveforms of reference signals representing known words. In Fig. 1, the electric signals are generated from the sound waves by a microphone 10, magnetic tape repeater 12 and associated transducers and read circuits 16, and are passed through normalizing control circuits including pitch compensation, word length detection and amplitude normalizing circuits to information processing circuits 26. The output consists of three frequency modulation components and three amplitude modulation components all at different frequencies which are assumed completely to define a spoken word. The six channels are switched in sequence to the Y plates of a tube 30 the X plates of which are connected to a time base 28 controlled by a word length signal, so that the six signals are displayed simultaneously. The reference signals are in the form of transparent lines 38 on segments 37 of a mask 36 continuously rotating at a constant speed. The images on tube 30 are projected through rotating mask 36 and the light falls on a photo-electric cell 46 and thus the output from amplifier 47 varies as each segment passes depending on the degree of matching of the displayed and reference signals. The maximum amplitude signal from cell 46 (corresponding to the best match) is stored by capacitor 51 on the first rotation of the disc and serves as a reference signal, signals generated at 46 during succeeding revolutions charging capacitor 52 to different levels, the charge on capacitor 52 being equal to that on capacitor 51 i.e. to the reference signal for only one reference pattern 38, which then corresponds to the word. This word is illuminated in a visual display by a light 60 which flashes each time the best match is obtained in response to an output from detector 57. Transparent binary indicia in each segment corresponding to the word permit light to pass to the detector circuit 61, which operates readout circuits 62 and a digital recorder 63. Specification 969,507 is referred to.

Abstract: 556,285. Releasable fastenings. BLACKBURN AIRCRAFT, Ltd., HAND, P. G. E., and WHITWORTH, K. A. April 21, 1942, No. 5363. [Class 44] [Also in Group XXXIII] For releasably securing the hood of an aircraft cockpit to the aircraft or to slides mounted thereon, the side edges of the hood each rest in a channel member spanned by pins engaged.by a slidable member, the two slidable members being displaceable from a remote point to disengage the pins and permit the edges of the hood to separate from the channel members. The side members 1 of the hood fit into channel members 11, the lower edges having notches 3 to fit over pins 12 extending between the walls of the channel. The slides 2 work in grooves in the sides of the members 1 and are notched at 4 to clear the pins 12. Hook-shaped extensions 5 adapted to engage beneath the pins 12 extend through openings in the bottom of each groove to enable the hooks to move into and out of engagement with the pins. An upward extension 13 on each slide passes through a notch 14 and over a scale on a plate 15 to indicate when the hooks are engaged with the pins. Two bell crank levers 6, having their short arms 7 engaging notches in the slides 2, are connected by Bowden or other cables to a lever 10 pivoted beneath a blister near the forward end of the hood. An upward thrust on the lever 10 consequently releases the hooks 5 from the pins and the upward pressure affects the initial opening of the hood. The channel members 11 may be moved to slide the hood by mechanism such as is described in Specification 556,284, [Group XXXIII].

Title: Telephones
IPC: H04M1/19
Filed: 1977-02-10
Abstract: In a U-shaped frame (1) which can be attached to a wall, a microphone (3) is disposed on its base surface (2) with a speech inlet (4). The lateral limbs (5, 6) of the frame are high enough to shield the speech inlet at the sides from ambient noise. A loudspeaker (7, 8) is disposed in each case on the inside of each of the projecting ends of the limbs. The aforementioned loudspeakers radiate the generated sound in a direction which is essentially parallel with the surface of the speech inlet. The distance between the loudspeakers and the microphone is only slightly greater than the average distance between the human ear and mouth. With this arrangement, the user is caused to move his ears closer to the loudspeakers when the sounds from the loudspeakers are weak and thus simultaneously to bring his mouth closer to the microphone. <IMAGE>
