Title: Improvements in and relating to Protective Devices for Dynamo Electric Machines.
IPC: H02H7/08
Filed: 1917-04-18
Abstract: 113,037. British Thomson - Houston Co., (General Electric Co.). April 18, 1917. Protective arrangements; automatic circuit-breakers.-Dynamo-electric machines are protected from ' flash overs ' on short-circuit or other abnormal conditions by means of a circuitbreaker which introduces a currentlimiting resistance in a time sufficiently short to limit the overload to the safe commutating capacity of the machine. As applied to a direct-current generator 1 having its positive side connected to a conductor 8 and its negative side grounded, the very rapid acting circuit - breaker 12 is located between the negative side of the machine and earth while an ordinary overload and reduced voltage circuit-breaker 9, operating with a smaller overload than the circuit-breaker 12, is located in the other side. With ordinary overloads the circuit-breaker 9 alone is operated, but with very heavy overloads, such as are liable to produce ' flash-overs.' the linkage system 19, 21, 24 which holds tho circuit-breaker 12 closed against the action of the powerful springs 18 is caused to collapse very rapidly by the movement of the lever 26 produced by the coil 27, thereby introducing the limiting resistance 13 in a shorter time than that required for a commutator-segment to pass from one brush to the nert. The circuit-breaker 9, which is slower-acting breaks the positive side subsequently. In the case of several machines supplying current in parallel, the rapid acting circuit-breaker 12 is inerted in the common earth connexion.

Title: Fastenings for attache and suit cases, bags, portfolios, purses and the like
IPC: E05B65/50
Filed: 1933-02-23
Abstract: 415,132. Hasp fastenings. CHENEY, C. W., Factory Road, Soho, Birmingham. Feb. 23, 1933, No. 5489. [Class 44.] A fastening for an attachÚ case, bag, purse, and the like, has a sliding bolt e with a nose e<3> to enter the loop of the hasp in the locking position. The bolt e is normally held in the unlocking position by its engagement with a projection i<3> on the spring i secured to the back plate at i2. The spring also carries a stud i<4> projecting through holes in the back and front plates. When the hasp is closed down, it engages the stud and depresses the spring i and the projection i<3>, so that the bolt is shot to its locking position by the spring f. The bolt can be withdrawn by hand-operation of the knob h, and release of the hasp again permits the spring i to move the projection i<3> to engage the bolt. In a modification the bolt end passes completely across the slot g in the locking position. In the form shown in Fig. 8, the bolt is held in the unlocking position by the spring o which is moved by the loop of the hasp. In the further modification, shown in Fig. 9, an outside bolt h<2> forming part of the knob h moves over the adjacent edge of the hasp l when the bolt is in the locking position.

Title: Improvements in change speed gearing
Filed: 1957-02-18
Abstract: 813,872. Change-speed gear. VOREAUX, P. J. Feb. 18, 1957 (Feb. 22, 1956], No. 5501/57. Class 80 (2). In an automatic three-element planet train, for a motor vehicle, having input and output suns 1, 2 and a reaction carrier 4 for stepped planets, wherein the reaction carrier 4 is, in reduced drive, prevented from reverse rotation as by a oneway detent 6, or controllable positive stop, and carries centrifugal clutch shoes 7, which, when the reaction carrier 4 is caused to rotate forwards above a predetermined speed by momentary torque reversal, as by throttling the driving engine, clutch an input drum 12 to upshift to direct solid drive, with fully automatic return downshift by clutch release when the speed falls, the torque reversal which initiates this upshift is caused automatically by a centrifugal, hydraulic or electric engine-speed sensing device, modulated, if desired, by engine load, as sensed by enginethrottle opening. Where the reaction member 4 is held by a controllable positive stop, this may be released by the torque-reversing means, which may also be used to produce automatic declutching. The torque reversing means is rendered inoperative in direct drive. In Fig. 8, not shown, two (or more) such gear trains are used in series to provide four (or 2<SP>n</SP>) ratios, the trains being so designed that both change simultaneously in shifts between second and third ratios. The automatic torque-reversal device, with direct drive suppression, Fig. 7, comprises centrifugal masses 20a driven by the engine through helical gears 24a, 24b and acting leftwards, when the desired upshift speed is reached, through a rod 21a to cut off directly, hydraulically, or electrically, the engine fuel supply in opposition to a spring 22a adjustably compressed by the usual engine accelerator pedal or pressure fluid controlled thereby. The fuel supply is restored when the masses collapse on engine deceleration, and after the upshift any further fuel cut-off is prevented by the torque reversal suppressor which comprises two plates 26a, 27a held together by non-rotary flanges 30a, one plate 26a being screwed at 28a on an axially fixed rod 19a pinned to the enginedriven helical wheel 24b, whilst the other plate 27a has an axially free drive connection with a helical wheel 25b driven through a wheel 25a by the output shaft 2 of the gear, the ratios of the gear pairs being so chosen that the wheel 25b rotates faster than 24b in direct drive and slower in reduced drive. Thus, in reduced drive the assembly occupies the ineffective position shown, whilst in direct drive the speed difference screws the plate assembly leftwards along the thread 28a, taking up the clearance b and taking along a rod 31a, which acts on the torque-reversing means directly or through hydraulic or electric means, to prevent its operation.

Title: Improvements in and relating to modulated carrier wave signalling systems
IPC: H04B1/68
Filed: 1937-03-01
Abstract: 491,093. Wireless systems ; filter networks. ECKERSLEY, P. P., and CARPENTER, R. E. H. March 1, 1937, No. 6126. [Classes 40 (iii) and 40 (v)] Harmonic distortion in an asymmetric sideband modulated carrier wave transmission system, is reduced by making the attenuation of components of frequencies within 1500 cycles per second of the carrier frequency, of one sideband, less than 8 db.; the attenuation of components of the same side band between 1500 and 4000 cycles increasing by at least 20 db. The phase displacement between the resultant side-band vector and the carrier vector, at least up to 3000 cycles per second from the carrier frequency is made less than 60. The desired attenuation and phase characteristics may be obtained by employing band-pass and band-elimination filter sections with suitable characteristics. The constant K bandpass section BP is coupled by a resistance pad RP or valve stage to the band elimination section BE, the combined filter being placed in the modulated carrier channel in the transmitter or in the receiver prior to detection. The carrier frequency f0 is located between the lower cut-off frequency f1 and fm (thegeometric mean between the upper and lower cut-off frequencies of the section BP), and nearer to f1 than fm. The upper cut-off frequency of the section BE is somewhat lower than f1 and the combination of the two sections produces the required characteristics ; the attenuation and phase shift characteristics being better then those of either section alone. The bandpass and band-elimination sections may be reversed in position or replaced by other sections of suitable type. The output circuit of the amplifier feeding the first filter portion, Fig. 8 (not shown), is shunted by a resistance small compared with the filter input impedance so that variations of the filter input impedance do not affect the loading of the amplifiers. Instead of the two filter sections described, a constant K type filter terminated in an M derived section may be employed to produce the differential attenuation and additional means provided to correct for the phase distortion. Specification 445,431 is referred to.
