Title: Speech synthesising apparatus
IPC: G10L19/00
Filed: 1975-12-19
Abstract: Speech synthesizing apparatus is provided in which different sounds are required for a plurality of channels. The channels are polled in turn on a cyclic scanning basis, the scan for each channel occupying a channel sampling period during which an instantaneous value is generated for the amplitude of a voiced sound component. Values representing instantaneous amplitudes of each of a plurality of unvoiced sounds are separately generated in turn during the period occupied by the scanning of all the channels and these values are stored. A selected one of the unvoiced sound values is extracted from the store as required for a particular channel during the sampling period for that channel, so that an updated value for the unvoiced sound is available on each occasion that that particular channel is sampled. The voiced and unvoiced sound values are then combined during the appropriate sampling periods. The required sound combinations are specified by parameters expressed in digital form for each channel separately.

Title: Self-adjusting mechanical seal with bellows control
IPC: F16J15/36
Filed: 1965-12-14
Abstract: 1,108,119. Mechanical seals. BORGWARNER CORPORATION. 14 Dec., 1965 [31 Dec., 1964], No. 53095/65. Heading F2B. A mechanical seal for a rotary shaft 12 comprises two axially movable non-rotatable coaxial seal-rings 21 and 22 interconnected by a bellows 39 and having sealing faces 24 and 26 respectively co-operating with an opposed face 25 of an axially fixed rotatable seal ring 13, the inner seal ring 21 being sealingly connected to the shaft housing 10 by further coaxial bellows 29 and 33 and the seal rings 21 and 22 being urged axially towards the ring 13 by means responsive to the differential pressures across the bellows-33 and 39. The ring 13 is fixed to the shaft 12 and the ring 21 is connected by the bellows 29 and 33 to rings 32 and 36 respectively forming part of a case 23 fixedly mounted in the housing 10. The interior space 48 of bellows 39 communicates through the space 50 between the rings 21 and 22 with the space 51 between the sealing faces 24 and 26 and the chamber 49 between the bellows 29 and 33 communicates via holes 52 in the ring 21 with the space 48. A clearance 47 between the rings 21 and 32 and a shaft sleeve 18 is open to atmosphere through the shaft opening 11 in the housing 10 and ports 43 and 44 in case 23 ensure that the exteriors of bellows 33 and 39 are subject to the pressure in housing 10. The seal is designed so that in normal operating conditions the pressure drops across faces 24 and 26 are substantially equal, the relative axial positions of the rings 21 and 22 and thus the leakage rates across the faces 24 and 26 being automatically controlled by the fluid pressure in the spaces 48 and 49. To ensure rapid increase of the pressure in space 48 to the operating pressure when a sudden increase in pressure occurs in the housing 10, the seal ring 22 is formed with an annular chamber 55 communicating by holes 56 with the face 24 and closed by a bellows 54. A large increase in pressure in the housing 10 moves the sides of the ring 22 together to cant the face 26 away from the face 25 to allow liquid to leak freely from the housing to the space 48 and also to the chamber 55 until the normal operating pressures are reached therein, the sides of the ring then being restored to their normal condition by the pressure in chamber 55. In a modification, Fig. 6 (not shown), three axially movable coaxial seal rings (121), (121a) and (122) co-operate with a member (113) fixed to the rotary shaft (112), ring (121) being connected to case (123) by bellows (160), (161) and (162) and to ring (121a) by bellows (129) and (133), and rings (121a) and (122) being interconnected by a bellows (139).

Abstract: 1,176,660. Cleaning filters. BENDIX CORP. 19 Dec., 1966 [20 Dec., 1965], No. 56626/66. Heading B1D. Cleaning of filter element 18 is effected continuously by unfiltered coolant from 9 flowing over the surface of element 18 in a spiral path defined by helical rubber strip 26 and leaving at 20, and intermittently by a periodic back flow of filtered coolant which is drawn off through pipe 24 or from filter outlet pipe 24, stored in chamber 32a, and automatically periodically discharged back into pipe 24. The restriction imposed by strip 26 increases the velocity of flow of coolant over the surface of element 18. The automatic periodic discharge of filtered coolant from chamber 32a is effected by a timing device which periodically causes solenoid 34a to shift valve 40 to connect pressure source 42 to chamber 32b which causes diaphragm 44 to move downwards, forcing coolant out through 24a. Only part of the coolant from chamber 32a passes through the filter element, the remainder maintaining the flow from pipe 24 to a machine tool during the backwashing process. Filter 18 may be wire wound or a perforated metal cylinder. Solid debris concentrated in a small fraction of coolant flows from outlet 20 to reservoir (6) from which coolant is pumped to the filter and thence to the machine tool.
