Title: Improvements in and relating to wheel hubs with a built-in dynamo
IPC: B62J6/12
Filed: 1960-07-05
Abstract: 894,242. Toothed gearing; friction gearing. FICHTEL & SACHS A.G. July 5, 1960 [July 30, 1959], No. 23532/60. Class 80 (1). [Also in Group XXXV] The rotor of a hub dymamo is driven by the hub sleeve through eccentric epicyclic gearing comprising an input rolling member driven by the hub sleeve, an output rotating member which drives the dynamo rotor (field member or armature) and which is concentric with the input member, and an eccentrically mounted rolling member which is mounted on the output member and engages with the input member, and is secured against rotation about its own axis. In one embodiment, hub sleeve 26 has a toothed ring 70 which may be engaged with toothed ring 68 to drive input rolling member 62 having internal toothing 60. Eccentrically mounted rolling member 54 having external toothing 58 engaging with toothing 60 is mounted on an eccentric cam 50 which drives the dynamo rotor 44. Output winding 38 may be rigidly attached to spindle 18 or may rotate with the hub sleeve (Fig. 7, not shown). Rolling member 54 is secured against rotation by a rectangular plate 126 (Fig. 8), with an aperture 128 loosely receiving spindle 18. Two opposite edges 134 of plate 126 are displaceably guided in a groove in member 54, and the remaining edges 130 are displaceably guided in a groove in member 88 (Fig. 1), rigidly attached to the spindle. In an alternative arrangement for preventing rotation the rectangular plate is replaced by a circular plate (Fig. 6, not shown), having four radial slots into which fit two pairs of pins, one pair rigid with member 54 and the other pair with member 88. In a second embodiment (Fig. 4) hub sleeve 26 drives a coupling member 106 which in turn may be engaged to drive input rolling member 98 having external toothing driving internal toothing on eccentrically mounted rolling member 92, which is mounted as before on eccentric cam 50. In both embodiments the gear train is coupled to the hub sleeve through a displaceable member 64 which is moved axially by a dog 80 extending radially out of the hub spindle 18, and a draw rod 78 attached to the dog and extending axially through the spindle so that the dynamo can be disengaged. In an alternative embodiment for disengaging the dynamo (Fig. 9, not shown), member 88 (Fig. 1), which was rigidly attached to the spindle and prevented rotation of rolling member 54 is replaced by an internally-toothed member which may be rigidly connected to the spindle by engagement with an axially movable externally-toothed member non-rotatable on the spindle. When eccentrically-mounted member 54 is free to rotate the transmission is non- operative. The engaging surfaces may in all cases be in frictional or toothed engagement. The rotor may be mounted on the hub sleeve instead of the spindle.

Title: Pacemaker
IPC: A61N1/362
Filed: 1973-05-17
Abstract: 1433787 Heart pacers ULTRASCHALITECHNIK HALLE VEB 17 May 1973 23596/ 73 Heading A5R [Also in Division H3] A heart pacemaker comprises a pulse generator in which the pulse duration depends on the heart's resistance and the voltage of the power supply, so as to supply substantially mono-energetic pulses to the heart. The power supply terminals are connected to the heart RH via a switching transistor T1 which is 'turned on and off by a multivibrator T3, T4 whose pulse width and repetition rate are determined by resistors R7 and R4 respectively. The multivibrator T3, T4 and hence the switching transistor T1 are controlled by a capacitor C2 across which a transistor T2 is connected. The transistor T2 becomes conducting and shorts the capacitor C2 when a capacitor C1 reaches a given voltage after charging up through the heart RH and the transistor switch T1. The time taken by the capacitor C, to reach the given voltage therefore depends on the heart resistance and the supply voltage, and these two parameters therefore determine the output pulse width.

Abstract: 1,116,491. Spectral analyzing apparatus. BLOCK ENGINEERING Inc. June 4, 1965 [June 11, 1964; March 1, 1965], No.23908/65. Heading G1A. [Also in Division G2] In detecting the intensity of a relatively weak spectrum line in the presence of a relatively strong substantially continuous background, for instance, for monitoring the amount of copper present in a mass of molten steel, an interferometer is used and one of its parameters such as path length is continuously varied so that the intensity of the required line is modulated whilst the relative intensity of the transmitted portion of the continuous background is maintained substantially constant. As shown, Fig. 5, the input radiation 26 is passed through an interference filter 34 which passes a region (15), Fig. 1 (not shown) including the required line (10), to a Michelson interferometer 20 whose mirror 27 is continuously oscillated by a signal 29 through mirror drive 28, the fringe pattern being focused by lens 36 on to photo-multiplier 35. Since a graph of intensity against wavenumber is a squared sinusoid and dependent on the parameters of the interferometer, by varying the path difference appropriately, a 100 per cent modulation of the intensity of line (10) can be made, Figs.2, 3 (not shown). The output of photo-multiplier 35 is amplified at 37, demodulated at 38 by a signal supplied from source 29, filtered, rectified and displayed at 39. To obtain maximum modulation of the line intensity so that the output of the photomultiplier contains no second harmonic a feedback loop is arranged from source 29 through frequency doubler 60 to a null seeking device 61 which generates an output only when the signal input thereto indicates that there is a variation from the fundamental frequency desired. When such variations occur device 61 generates an output applied to the drive bias of mirror drive 28 to offset the effect of variation from the fundamental frequency. Amplitude control of signal source 29 is also provided to obtain the maximum output at 39. A compensator 31 increases the retardation without increasing the geometric length by providing a virtual reflecting surface within glass plate 32 Fig. 6 (not shown). In further forms a Fabry-Perot interferometer is used.

Abstract: 1302491 Tape loading; cassette loading SONY CORP 19 April 1971 [14 Feb 1970 (2)] 23990/71 Heading G5R In an automatic tape loading system, magnetic tape T is withdrawn from a cassette 23 and wrapped around a rotary heads drum 24 for helical scanning. In the arrangement shown, a pin 38 on an arm assembly 39 which is mounted on an inclined rotary support ring 32 engages the tape in an " inactive " position T 1  (Fig. 1). The ring is then rotated clockwise to withdraw a loop L, and by continuing the rotation a final " active " position is reached (as in Fig. 2) wherein one portion L<SP>1</SP> 1  of the final loop L<SP>1</SP> is in the desired position for scanning by the heads (25, Fig. 3, not shown), the portion L<SP>1</SP> 2  of the loop L<SP>1</SP> being maintained clear of the portion L<SP>1</SP> 1  by guides 52-56 which are mounted on the ring 32 and which, during the rotation of the ring, successively enter the loop owing to the generally inclined orientation of the ring relative to the loop. Radial movement of arm assembly 39 relative to ring 32 is controlled by a cam member 49 and a follower in the form of a bent tab 51. The ring 32 also supports a two-roller pinch roller assembly 57, the rollers when brought to the correct position being pressed against the capstan assembly 66 by a member 74 of a pressing and latching assembly 73. Cassette loading/ejecting system, Fig. 10; a cassette on a carriage 128 is pushed horizontally and a guide pin 141<SP>1</SP> moves along a horizontal slot 142a; the carriage and cassette then fall under gravity to the lower position shown where the guide pin is held by a latch 152, and where the pin 38 is in the position shown in Fig. 1. The latch 152 is automatically unlatched by a link 156 when the tape returns to an inactive position from an active position, and an arm 151 may then be manually operated to cause a lever 148 to lift the carriage 128 for ejection of the cassette. To accommodate cassettes of different dimensions, one reel drive assembly (179, Fig. 15, not shown) is mounted on a pivotable bracket (184).

A difference between the two jet forces acts to deflect the blade 1 relative to a nozzle 5 supplied via a restrictor 7 by a line 6. A signal proportional to the force difference is thus created in line 8 and this is fed via an amplifier 9 and a restrictor 11 to a further nozzle 10, the action of the latter on the blade being in the manner of a negative feedback. In various modifications, not shown, two opposed nozzles are used to the feedback line Fig. 2 (not shown), two spaced and interconnected resilient blades are provided instead of the single blade Fig. 3 (not shown), and only one jet or other force applying means is used to deflect the blade Figs. 4 and 5 (not shown). In all embodiments the deflection-detecting nozzle and the feedback line nozzle or nozzles are supplied via a respective resistance and/or capacitance.

Title: Devices for preventing retrograde movement of vehicles
IPC: B60T7/12
Filed: 1935-08-30
Abstract: 447,526. Preventing reverse movement of vehicles. GONARD, J. L., Hudson Terrace, Englewood Cliffs, Bergen, New Jersey, U.S.A. Aug. 30, 1935, No. 24286. [Class 103 (i)] One-way braking element for preventing reverse movement of a motor-vehicle operates on the gear-box main-shaft in forward speed and neutral and is put out of action by a lever having a pin-and-slot connection with the reverse and first speed gear shifting element when the gear lever is moved to reverse and remains out of action when moved to neutral after reverse and until the gear lever is moved to the first forward speed position and remains operative during all forward speed positions. A one way ball clutch comprising a ring gear 46 held against rotation in one direction by balls 69 in inclined slots in a fixed plate 47, meshes with a gear 45 fixed on the main shaft of the gear box which is always connected to the vehicle rear wheels. Plate 47 can be turned a small amount to put the rollers out of action and render the gear 46 free, by a yoke 80 operated by pin 85 and a cam slot 86 in a plate 87 slidable on rods 89, 100 in the top of the gear box. The plate 87 is adapted to be moved by a lever 93 mounted on a fixed pivot 94. The lever 93 is operated by a pin 102 engaging in a triangular opening 101 in the lever 93 and fixed to the gear shifter element 30 which is adapted to move the gears into low and reverse gear. In the position shown in Fig. 2, the gears have been moved to reverse position and the one way ball clutch 46 has been put out of action and the vehicle may move backwards. When the gear lever is moved to neutral position, the gear shifter element 30 is moved to the right to bring slots 111, 112 in the gear shifter elements 30, 32 in line and pin 102 moves along the side 104 of the opening 101 without moving the lever 93 so that the ball clutch 46 remains inoperative and the vehicle can still be moved backwards. When the gear lever is moved to low gear position the element 30 is moved further to the right and the pin 102 engages the side 105 moving the lever 93 so as to put the clutch 46 into operation. Movement of the shifter element back to neutral merely moves the pin 102 along the side 103 of the slot 101 without moving the lever 93. Further movement of the gear lever to move the element 32 for engaging second and top gear has no effect on the lever 93. A spring plunger 108 maintains the lever 93 in its two positions. The yoke 80 moves the rollers 69 into and out of operation by means of lugs 72, 74 fixed to plates on each side of the plate 47. The position of the plate 47 is adjustable.

Title: Combustion control circuit for a fuel burner
IPC: F23N5/20
Filed: 1973-05-22
Abstract: 1428819 Burner controllers WEBSTER ELECTRIC CO Inc 22 May 1973 [25 May 1972] 24332/73 Heading F4T A burner 12 having a fuel and air supply motor 14 and an igniter 16 is controlled by a circuit 10 comprising a triac 46 operable to energize the motor 14 and igniter 16 simultaneously, a photoresistor flame detector 74, a heat-demandsensing thermostat switch 22 or 24, a first control circuit 20 coupled to triac 46 and to the thermostatic switch for rendering triac 46 conductive when the switch 22 or 24 closes, a second control circuit 28 coupled to the igniter and to the flame detector 74 for discontinuing igniter operation when a flame is sensed, a thermal delay switch 30 for preventing operation of motor 14 when the switch 30 is heated to a predetermined extent, a first heater resistor 87 for heating switch 30 during operation of circuit 20 prior to operation of circuit 28, and a second heater resistor 100 for heating switch 30 during operation of igniter 16. The control circuit has a fan over-temperature switch 44, and either a line thermostat switch 22 or a low voltage thermostat switch 24. Closure of the thermostat switch effects start-up of the burner by energizing a first relay winding 50 and by energizing a second winding 48, fed via an SCR 56 rendered conductive by a first state of unbalance of a bridge 62 having photoresistor 74 in one leg an fed by a regulated supply including Zener diode 58. Only if both windings 48, 50 are energized is a contact 52 closed to gate on triac 46, current through winding 50 only being sufficient to hold contact 52 closed. Triac 46 energizes motor 14 and, via heater resistor 100, igniter 16 comprising a spark-gap 92, 94 fed by relaxation oscillator 108, 110. If ignition is not achieved before switch 30 is heated to the predetermined level by resistors 87, 100, a bimetal 120 opens contacts 118 to de-energize the control circuit and burner. If ignition is achieved before contacts 118 open, bridge 62 swings from the first state of unbalance through the null position to a second and opposite state of unbalance in which SCR 56 is off thus de-energizing winding 48 and allowing a coupling transformer 122 to render SCR 110 non-conductive to turn off igniter 16. Transformer 122 may be replaced by a relay having a coil shunted by SCR 56, or by a lamp shunted by SCR 56 and illuminating a photoresistor across the gate-cathode circuit of SCR 110. When the demand for heat is satisfied switch 24 opens to de-energize winding 50 and turn off triac 46; or switch 22 turns off triac 46 directly. If during burner operation the flame goes out SCR 56 is gated on and winding 48, heater 87 and igniter 16 are energized and a triac-for-ignition is initiated as during burner start-up. If triac 46 fails in a short circuit mode when the flame is out, igniter 16 becomes, or continues to be, energized and heater 100 acts to open contacts 118 and de-energize the burner and control circuit. The thermal delay switch 30 may be arranged to lock-out, requiring manual resetting, on opening of contacts 118.
