Title: Automotive accessory drive by planetary gearing
IPC: F02B67/04
Filed: 1981-01-21
Abstract: A three-phase accessory drive system associated with the engine of a vehicle and providing a high ratio drive phase from vehicle engine idle to a first predetermined engine speed, a substantially constant speed drive phase above the first predetermined engine speed to a second predetermined engine speed and a low ratio drive phase above the second predetermined engine speed. The accessory drive speed is also temperature compensated (by a bi- metal support arm 94 carrying a valve member 92 cooperating with an orifice 90 in a conduit 82). The drive system comprises the combination of a planetary gear set 18, a spring-applied friction brake 48, a one-way friction clutch 96 and a hydraulic system for progressively releasing the brake. The gear set comprises an engine-driven planet carrier 16, a sun gear 44 on which the brake 48 acts, and a ring gear 26 which carries output pulleys 30, 38. The hydraulic actuator 56 for releasing the brake receives hydraulic pressure from a pump 58 driven by the ring gear. <IMAGE>

Title: Antimicrobial Surgical Implants
IPC: A61F2/02
Filed: 1981-03-26
Abstract: Surgical implants, especially endoprosthetic orthopaedic implants and sutures, are rendered antimicrobial by the presence of a bioerodible metallic silver component, especially a surface coating, which provides in vivo a sustained release of silver ions in a concentration sufficient to provide a localized antimicrobial effect but insufficient to cause significant damage to connective tissue. Latently bioerodible silver components of an implant can be activated by, for example, abrasion, heating to above about 180 DEG C or, especially, contact with hydrogen peroxide. For example, an implant pin 2 of Ti alloy is coated at 1 with silver by film evaporation and subsequently placed in a culture plate 3 inoculated with Staphylococcus aureus, and incubated. A zone 4 of inhibition is apparent. <IMAGE>

Title: Mechanical Time-Setting Device for a Watch Having Analogue Time Indication
IPC: G04B27/02
Filed: 1981-10-22
Abstract: The time-setting device comprises a key and a time-setting gear train. The key comprises a cylindrical shaft 112'' rotatably mounted and sliding in a tube integral with the back 6 of the case. A mutilated toothed wheel 118 is fixed to the inner end of the shaft. A blade 116 is mounted for pivotal movement about the outer end of the shaft 112''. The blade 116, in the folded back position, can be introduced into a seating 126 formed in the back of the case. A return spring 140 normally maintains the wheel 118 above the adjusting wheel 22. When the blade 116 is in the angular position for being introduced into the seating 126, the un-toothed recess 118c of the multilated wheel 118 is directed towards the wheel 22 so that the teeth of the wheels 22 and 118 do not clash when the shaft 112'' is pulled out by the blade 116 for time-setting by turning the blade and shaft. After release of the blade, the spring 140 returns the shaft and wheel 118 to the retracted position (Figure 3a) in which the blade can be freely rotated for introduction into the seating 126. <IMAGE>

Title: Fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1981-12-09
Abstract: A fuel injection pumping apparatus of the axially slidable rotary distributor type includes a cup shaped member 14A mounted on a drive shaft 14 and a distributor member 28 which has a bore 29 containing pumping plungers 30. The outward movement of the plungers is controlled by a tapered surface on the interior of the cup shaped member which co-acts with complementary surfaces on cam followers 44, 45 disposed between the plungers and a surrounding cam ring 41. The slots 16 in the cup shaped member which accommodate the followers are of helical or like form and the distributor member is driven angularly by tongues which are secured to the distributor member and which locate in the slots. As the distributor member moves axially it is also moved angularly by the action of the helical slots so that the timing of delivery of fuel remains constant. <IMAGE>

Title: Control apparatus for single phase AC induction motor
IPC: H02P25/04
Filed: 1982-01-27
Abstract: A control apparatus establishes a rotating field in a single phase AC induction motor (10 Figure 1), which has a rotatable output and first (12) and second (14) sets of mechanically displaced windings, by energising at least one of these two sets cyclically from the single phase AC input. The other winding may be continuously energised. As shown the control includes first and second solid state switch means (18,20) for interconnecting the first and second sets of windings, respectively, of the motor with the AC input. A controller (26) is responsive to the single phase AC wave form for controlling the conduction of the first and second switch means and rendering each of the switch means alternately and cyclically conductive for discrete time periods during each cycle of the single phase AC wave form on the input (Figures 3, 4, 7 and 8). Free-wheeling solid state switch means (22,24) alternately conduct when switch means (20 and 18) conduct respectively. The solid state switch means may be a diode connected bridge with a transistor across one diagonal thereof (Figure 9), a complementary pair of transistors, FET power transistor or triacs. In a further embodiment (Figure 2) the windings (12 and 14) are connected in series and a switch means (30,32) is connected in parallel with each winding and conduct alternately. This embodiment eliminates the need for additional free wheeling switches as the conductive switch means (30,32) provides this function to its parallel connected winding. <IMAGE>

The annulus safety valve includes a housing having fixed seals engaging the tubing wall above and below the sleeve valves, a valve tube assembly including an annular valve member in the housing, springs for closing the valve member, a hydraulic piston for opening the valve member, and annular flow passages along the housing and valve tube assembly past the valve member for conducting fluids from the lower sleeve valve (35) past the packer to the upper sleeve valve (33). The annulus safety valve is held open by control fluid pressure, closed by spring force, and may be pumped open by fluid in the annulus above the valve. The only moving seals of the annulus safety valve are protected internally. <IMAGE>
