Title: Improvements in change speed gearing specially adapted for motor vehicles
IPC: F16D23/04
Filed: 1931-06-04
Abstract: 371,655. Change speed gearing. BRETTELL, F. G., 59, Chancery Lane, London.-(L. G. S. Devices Corporation ; Indiana, U.S.A.) June 4, 1931, No. 16262. [Class 80 (ii).] In change-speed countershaft gearing suitable for vehicles, both in direct drive and in second speed a free-wheel or a locked drive may be used at will, the free-wheel clutch being of the coil type. The one-way driving coil 49 is anchored at 50 to a cup member 31 splined to a driven shaft 12 and extends into a cup member 30 loose on the same shaft. A clutch member may connect either a driving shaft 11 or a countershaft-driven loose gear 43 to the cups 30, 31 alternatively to yield one-way or locked drives to the shaft 12. The control clutch member or sleeve is in two parts 56, 52 which can turn relatively but are constrained to slide together by a connection 62. The neutral position is shown in Fig. 1. Clutch teeth 15 integral with the shaft 11 engage dedendum teeth 58 on the sleeve 56 while full teeth 57 on that sleeve engage full teeth 22 on the sleeve of a countershaft-driving pinion 21, so that there is no load drive but a countershaft 25 is driven idly. First speed and reverse are effected by sliding a splined gear 44 by a shift rod 8, while direct drive and second are effected by sliding the clutch sleeves 56, 52 by a fork 60 and rod 7. A partial movement of the rod 7 to the left brings to the position of Fig. 2 in which there is one-way direct drive. Power passes from the teeth 15 through the sleeve 52 to the loose cup 30, and on through the coil 49 Since the sleeve 56 is not driven, the pinion 21 and the countershaft gears are all at rest. Completed leftward movement brings in the direct locked drive. The teeth 15 still drive the sleeve 52, clutch teeth 53 on which now engage and drive teeth 40 on the fast cup 31, the coil being idle. The countershaft is still at rest. The parts in returning to neutral must pass the position shown in Fig. 2 in which a spring plunger 55 carried by the sleeve 52 engages a notch in the cup 30. This plunger by resisting the rightward thrust of the fork 60 causes friction cones 63 on the clutch sleeves to bind so that the sleeve 56 is set in rotation and its teeth 58 are synchronized to pass between the teeth 15. A partial movement to the right from neutral brings to the position of Fig. 4 with a one-way second-speed drive. The sleeve 56 drives only to the pinion 21 so that the loose gear 43 is countershaftdriven. From clutch teeth 42 on that gear the drive passes by the sleeve 52 to the loose cup 30 and on through the one-way coil. Completed rightward movement brings in the locked second speed because the coil is cut out by teeth 53b within the sleeve 52 engaging the teeth 40 on the fast cup 31.

Title: Method of regulating the filling of a container or apparatus
IPC: B02C19/06
Filed: 1935-06-11
Abstract: 444,521. Pneumatic conveyers ; hoppers. GRAEMIGER, B., 75, Stampfenbachstrasse, Z³rich, Switzerland.. June 11, 1935, No. 16840. Convention date, June 11, 1934. [Class 78 (i)] [See also Groups II and XXIX] A method of maintaining a constant level of material in a container comprises a rotating body so positioned in the container that when the level of material rises above the normal level a braking action is applied to the motor driving the rotating body whereby the power supply to the motor regulates a control in the supply of material to the container. As shown applied to a jet pulverizer, the height of material in the pulverizer is controlled by the movement of a gate 24, Fig. 1, connected to a piston 18 in a cylinder 17. The underside of the piston is connected by a pipe 16 to an indicator 80 and to a fluid pressure inlet pipe 15 supplying fluid pressure to a motor 11 which exhausts through outlet 14. The motor shaft rotates members 10 above the material in the pulverizer and when rotating freely, the pressure in the pipe 16 is reduced and the spring 19 above the piston 18 maintains the gate 24 open. When the members 10 contact with the material in the pulverizer the motor speed is reduced and the pressure in the pipe 16 increases to overcome the resistance of the spring 19 and close the gate 24. In a modification, the piston is connected to a sliding sleeve controlling the feed to a rotary plate and fixed scraper. In Fig. 3, the pipe 16 conveys pressure fluid to a cylinder 40 containing a bellows 41 and spring 42. The upward movement of the bellows operates a piston valve 45, 46 which admits pressure fluid from port 48 to port 49 and thence by pipe 51 to a motor 53, the exhaust returning by pipe 52 to exhaust port 50. The motor rotates a wheel 55 which moves a rod 58 connected by lever 61 to a mixing tube 2 in the pulverizer, the movement of which controls the flow of material through inlet 8. In Fig. 4, material from a hopper 72 is agitated by oscillating plates 71 and falls on to a platform 78. The exhaust from the motor 11 is connected to an inlet 76 above the plate 78 and blows the material through shoot 8 to the pulverizer. Electric motors may be used and the motor 11 may be in circuit with the motor driving the charging device so that the speed of both motors varies simultaneously. The member 10 may have a reciprocating movement and light and sound signals may be operated.

Title: Compatible am stereophonic receivers
IPC: H04H20/49
Filed: 1976-04-27
Abstract: 1516433 Stereo receivers L R KAHN 27 April 1976 [2 May 1975] 17051/76 Heading H4R In an AM stereo receiver for receiving a stereo signal wherein a signal (L+R) is amplitude modulated on a carrier and a signal (L-R) is phase modulated on the carrier, the detected amplitude signal (L+R) is inverse amplitude modulated onto the received carrier prior to its demodulation in a quadrature demodulator. The receiver is a development of that disclosed in Specification 970,051. A pilot tone may be transmitted to indicate the presence of stereo signals, the tone being used to light a stereo lamp and/or to automatically switch the receiver to a stereo mode. Extensive use is made of integrated circuits. The output of the IF stage of the receiver is split into two paths at 16, the first path comprising conventional AM detection circuitry to produce at 38 the (L+R) signal which is supplied in known manner to logic circuits 64, 66. The phase detection path includes a carrier track circuit 20 for producing the basic carrier frequency which is supplied both to a quadrature demodulator 36 and to an adding circuit 24 to pre-emphasise the received signal. In an amplitude modulator 28 the pre-emphasised received signal is inverse modulated with the (L+R) signal for supply to quadrature demodulator 36. The arrangement reduces harmonic distortion, and a further reduction can be obtained by also adding the second and third harmonics of the (L+R) signal to the preemphasised received signal (see also figures 2 and 3, not shown), e.g. by use of frequency doubler 54 and frequency tripler (96). A carrier track circuit 20 employing a phase locked loop arrangement is disclosed in figure 6 (not shown), and a second arrangement known per se in figure 7 (not shown). In place of envelope detector 18, a product demodulator may be used for deriving the (L+R) signal (figure 8, not shown). The pilot tone for mono/stereo switchover may be either amplitude or phase modulated on the carrier, the former method being preferred. In connection with the latter method Specification 1,509,212 is referred to.

[Class 80 (ii).] In variable-speed ratchet gearing, reciprocal rack frames 6 pass transversely through a drum 5 fast on a driving-shaft 2 so as to revolve end-over-end. As the drum 5, Fig. 2, turns, a roller 20 on the advancing end of a rack frame engages at A an eccentric cylindric surface 19. When that roller leaves the surface 19 at B, the rack frame 6 has been thrust into the drum 5. It is thrust back again in the next half-revolution. Each frame carries two racks 7, 7a in different planes engaging pinions 8, 8a, Fig. 1, loose on a driven shaft 4 concentric with and inside the drum 5. Each pinion is rigid with a cup oscillator 9 which through one-way grip rollers 13 imparts oneway drive to a rotor disc 11 fast on the shaft 4. The four rack-andpinion pairs shown act in alternating phases. The speed is varied by shifting laterally a non- rotary barrel 15 which supports the tread surface 19. The barrel 15 is adapted to slide in guides 1b, Fig. 2, in a fixed casing 1 and is operated by a screw 16 and worm 18.
