Title: Centrifugal speed governors for fuel-injection internal combustion engines
IPC: F02D1/10
Filed: 1973-12-04
Abstract: 1451059 Speed governors ROBERT BOSCH GmbH 4 Dec 1973 [5 Dec 1972] 56019/73 Heading G3B A centrifugal speed governor for a fuel injection I.C. engine includes a control device for preventing, when the engine is hot, the excess fuel normally supplied on starting. The governor comprises an operating lever 58 which is rigidly connected to a shaft 57 carrying a guide lever 56, the lever 56 acting as a slotted lever 43 and varying the quantity of fuel injected by regulating the position of the control rod 45; flyweights 12 acting through a governor sleeve 16, guide lever 42, drag lever 95 and slotted lever 43; a first cam plate 69 which determines the maximum fuel injected dependent on engine speed and a second cam plate 77 which renders part of the first cam plate 69 inoperative when the engine is hot. The first cam is made speed dependent by connecting it to the guide lever 42 via drag member 73 and driver 72. The two cams co-operate with a follower member 68 which is linked to the control rod 45. When the quantity of fuel is increased the rod 45 moves in direction C, Fig. 6, unless prevented by the follower member 68 abutting the cams 69, 77. When the engine is cold and not running, excess fuel is injected on starting by providing a notch 93 on the first cam 69. If the engine is hot cam 77 is rotated by a bi-metallic strip 82 so that the notch 93 is non operative. The cam 77 may be profiled as shown to provide degrees of obstruction depending on the temperature of the engine. The bi-metallic strip may respond to the temperature of the governor housing or the cooling water or engine lubricant Fig. 5 (not shown), or the liquid may be non flowing and heated electrically.

Title: Locking differentials

Filed: 1972-12-05
Abstract: 1396978 Differential gear ZAHNRADFABRIK FRIEDRICHSHAFEN AG 5 Dec 1972 [18 Dec 1971] 56071/72 Heading F2D In a locking differential of the kind in which side bevel wheels 15, 16 are axially displaceable on output shafts 44 and coact with multipledisc brakes, and the casing 1 has longitudinal grooves 5 to receive projections on alternate brake discs, the casing is open at one end, where it receives a cover 2, and the grooves 5, which may be open to the exterior of the casing over a part 8 of their length, extend to the open end of the casing and receive also the ends of the shaft or crossed shafts 10, 20 carrying the pinions 12 which shafts have inclined surfaces 13, 14 at their ends to correspond with inclined side walls of the grooves 5. The arrangement provides for lateral floating of the shafts 10, 20 to avoid the necessity for individual adjustment of the brake on each side of the gear set. As shown in the upper half of Fig. 1, the discs 18, 21 are held under pressure against an abutment ring 24 in a groove 25 by a plate spring 31, and axial displacement of a side wheel due to tooth reaction as transmitted torque increases is effective through a plate spring 30 on a portion 29 of a plate 28 to reduce the braking. An alternative arrangement shown in the lower half of the figure dispenses with the ring 24 and spring 30 and is such that braking is increased in response to increased transmitted torque. The outer faces of the pinions 12 may have spherical or planar surfaces backed by correspondingly shaped thrust washers.

Abstract: 1501080 Storage heater control circuit HOTPOINT Ltd 21 Feb 1975 [6 Dec 1973] 56495/73 Heading H2H [Also in Division G3] A fan storage heater incorporates a control circuit for operating the fan motor 14 to maintain a flow of air through the heater in dependence upon the temperature sensed by a temperature sensing device 17, which circuit also includes switch means SW operable to modify the operation of the fan for maintaining an airflow, when the heater is working from an offpeak supply, which is lower than that produced during peak-period operation at the same sensed temperature. As shown, a shaded pole A.C. motor 14 is connected in series with the A.C. terminals of diode bridge 21 across an A.C. supply. The circuit is completed via thyristor TH which is turned on at a point in the input ¢-cycles by the output from transistor pair TR1, TR2 which compares the voltage on capacitor C1 with that at the junction of negative coefficient thermistor 17 and resistor R2. In operation capacitor charges via R1, R4 and D1 and subsequently more slowly via R1 and R3, the rate of charging being set by temperature control potentiometer BV1. The firing point within the ¢-cycle of thyristor TH being set by both the rate of charge of capacitor C1 and the resistance value of thermistor 17. To achieve the required modified operation a normally open switch SW in series with a fixed resistor R8 and a potentiometer RV2 is connected in parallel with the thermistor so that closure of the switch connects resistances R8 and RV2 in parallel with the thermistor to effectively reduce its value. This parallel circuit may alternatively be connected across setting resistor RV1.

The magazine has downwardlydepending side portions 19, Fig. 2, which overlie side portions of the base and bear against the laterally-projecting portions of the spring member. The magazine includes a cover 29, Fig. 3, which carries a spring support 38 to retain one end 39 of a coil spring 32 which in turn is connected at its opposite end 41 to actuate a follower 43. A driver arm 48 is mounted above the magazine cover 29 and a top cap 49 is secured to the driver arm. The driver arm 48 has a rear portion 55 which retains in position a latch-button 28 used for opening the device so that staples may be inserted into the magazine. Stapling pressure is applied to the cap 49 causing a driver blade 35 to move within an opening (52), Fig. 8 (not shown). The spring 15 acts as a clearance spring maintaining a spaced relationship between the magazine and the base, and facilitating insertion of the work. The base is pivotally moved away from the magazine when the device is to be used as a tacker.
