Title: Pneumatically operated walking doll
IPC: A63H3/24
Filed: 1971-04-19
Abstract: 1346342 Dolls TOMY KOGYO CO Ltd 19 April 1971 [30 March 1970] 25510/71 Heading A6S A pneumatically operated walking doll, as shown, comprises a head, a torso which is swingable, an operating framework pivotally mounted within the torso and swingable with the torso, and a pair of legs attached to the framework which can be alternately swung forward. In operation, an air pump (22), (Fig. 1, not shown), is compressed and air is supplied to a servo 15 via a passage 15a. The pressure due to the servo 15 acts upon a support member 16 to tilt the torso 1 about a pivot 11 in the direction of an arrow P, against a tension spring 17. The weight of the torso is borne by the right leg, and the left side of the torso is raised, causing an arm 9 secured to the leg via a bearing 5 to turn upward about a horizontal shaft 6 as pivot; thus the foot 3' of the left leg is swung forward. As the air pump is released, the air supplied to the servo 15 is released, and the torso 1 is then tilted back leftward by the action of the spring 17, and the left foot 3' touches the floor and moves a step forward. The right leg, in the same manner as the left leg, is then caused to swing forward. The doll therefore moves forward as the air pump is repeatedly squeezed and released. Accessories, such as a balloon or flutes can be detachably attached to the doll's mouth, or a small toy dog can be attached to a hand via a flexible pipe, both these accessories being worked by separate pneumatic systems from that operating the doll.

Abstract: 432,073. Envelopes. CHAPMAN, C. H., and CHAPMAN, D. G., Grange Mills, Grove Road, Balham, London. Sept. 5, 1934, No. 25539. [Class 146 (ii)] An envelope of the type provided with a shallow pocket for the reception of the closure flap has a portion of the back extending to the mouth of the envelope formed with an integral continuation piece extending beyond the mouth in a lengthwise direction, and folded inwardly and downwardly as a single flap about a line parallel with the mouth, and provided with an upwardly extending tongue formed by cutting out a portion of the continuation piece by means of a transverse slit along the hinge or fold (or close to and parallel with it) at the mouth, and one or two side slits extending from the transverse slit in the lengthwise direction of the continuation piece, the safety pocket to receive the end closure flap being formed between the tongue and the envelope back. In the example shown, the envelope is made from a single-piece blank, the side flap 14 being of substantially the same width as that of the front portion 10 and preferably folded over first. A lengthwise continuation piece 16 provided at the upper end of the flap 14 is slit at 19, 20 to form a tongue 18, and is folded inwardly about a line 17, parallel with the envelope mouth, and gummed to the flap 14 by gummed surfaces 15 around the margins of the tongue. The closure flap 11 is inserted into the pocket provided by the tongue 18 and the envelope back 14. The slit 19 is preferably located out of alignment with the hinge line 17, so that the free edge of the tongue 18 will stand proud of the corresponding edge of the envelope back to facilitate insertion of the closure flap into the pocket. In a modification, the back of the envelope constitutes a separate piece having the continuation piece thereon and is held in position by the bottom and two side flaps. In another example, the bottom flap is approximately the same size as the front portion of the envelope and provided with the continuation piece, and is folded over the front portion and retained by two side flaps. In a further example, the two side flaps overlap and are each approximately half the width of the front portion, the continuation piece being formed on one side flap, and the upwardly extending tongue being formed by a slot which extends inwardly from the free edge of the flap along the hinge or line between the continuation piece and the side flap to a point short of the fold between that flap and the envelope mouth, and by a second slot extending from the terminating point of the other in a lengthwise direction of the continuation piece.

Title: Continuous speech recognition method
IPC: G10L15/00
Filed: 1978-05-31
Abstract: A speech recognition method for detecting and recognizing one or more keywords in a continuous audio signal is disclosed. Each keyword is represented by a keyword template representing a plurality of target patterns, and each target pattern comprises statistics of each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio. The spectra are processed to enhance the separation between the spectral pattern classes during later analysis. The processed audio spectra are grouped into multi-frame spectral patterns and are compared by means of likelihood statistics with the target patterns of the keyword templates. A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.

Title: Improvements in subaqueous sound producing devices
IPC: G10K9/10
Filed: 1920-09-09
Abstract: 151,602. Signal Ges. Sept. 22, 1919, [Convention date]. Diaphragm vibrators.-In a diaphragm vibrator for subaqueous signalling, operated by electric, hydraulic, or pneumatic means, the striker, which moves normally to the surface of the diaphragm, becomes released from the operating mechanism during the stroke, so that the dimensions of these two parts may be independently designed. As shown in Fig. 1, the diaphragm 1 may carry a vibratory structure comprising masses 2 and 3 connected bv an elastic member 4 and adapted to receive the stroke of the striker 5 which is projected, by the spring 6 and cushions against the rubber 8. The striker is withdrawn against the action of the spring 6 by energizing the electro-magnet 10. The armature 11, linkwork 12, and striker 5 move upwards as one piece, owing to the fact that the toggle 13 locks the linkwork in the position shown. At the end of the upward motion the pin 14 bends the toggle 13 and the striker 5 is projected by the spring 6 independently of the armature 11. When the armature drops, the parts resume the position shown. In a modification, the linkwork 12 is dispensed with and the striker 5 is connected to the armature 11 by a second electro-magnet formed integral]y with the armature. The striker is pulled upwards by magnetic attraction and released by de-energizing this second electromagnet. The electric circuits may be automatically opened and closed by the movements cf the above-mentioned parts. In a pneumatic modification, compressed gas is admitted from pipe 30, Fig. 3, through ports 32 to the lower side of a piston 29. The piston draws upwards the striker 37 to which it is connected by a leaf spring 34 backed by a block 35. The tension of the spring 40 eventually forces the shoulders 38, which are integral with the striker, to disengage from the leaf spring 34, when the striker is projected against the diaphragm 41 and cushions on the annular leaf spring 36. When the piston 29 reaches the top of its stroke the valve stem 30" meets the flange 70 and closes the ports 32, while the stops 45 open the valves 44. The piston 29 then falls and the parts resume the position shown. This device is suitable for buoys illuminated by compressed gas. Compressed air may be admitted alternately above and below the piston, and for hydraulically driven apparatus the spring 40 may be replaced by a leaf spring. In a further modification, a spring-projected striker is gripped by tongs which are opened by stops when they have been sufficiently drawn upwards, against the action of the spring, by rods actuated by a magnet or a piston. In all the above modifications, a system of levers may be interposed between the striker and the operating-mechanism and the action of gravity may be replaced by spring control.
