Title: Electronic timepieces with stepping motordriven analogue time displays
IPC: G04C3/14
Filed: 1978-04-19
Abstract: An electronic timepiece including a dividing circuit for developing different output pulse signals having different respective pulse repetition rates, a stepping motor and a drive circuit responsive to control signals for driving the stepping motor at a normal rate and for applying a correction pulse to the stepping motor according to the control signals. A pulse combining circuit combines the different output pulse signals from the dividing circuit for generating control signals and for applying the control signals to the drive circuit. The pulse combining circuit normally generates a control signal effective to drive the stepping motor at a normal rate, and the pulse combining circuit is responsive to a correction signal to control the drive circuit to apply a corrective pulse to the stepping motor. A detection circuit detects rotation and non-rotation of the stepping motor rotor and generates a detection voltage signal indicative of the state of rotation of the rotor. A voltage comparing circuit compares the detection voltage signal with a standard voltage value and applies a correction signal to the pulse combining circuit when non-rotation of the stepping rotor is detected after a drive pulse is applied to the stepping motor.

Abstract: 554,535. Barometers. BENDIX AVIATION CORPORATION. Dec. 5, 1941, No. 15738 Convention date, Dec. 6, 1940. [Class 106 (ii)] Comprises indicating means operated in response to changes in barometric pressure and reading against a scale, a marker co-operating with the scale and capable of being set independently of the indicating means, and display means operatively connected to the marker and giving a separate indication of the marker setting. The motion of a capsule or capsules 10 is transmitted by a pin 13 and bent arm 14 to a spindle 15. A quadrant and pinion 18, 19 transmit the motion to a spindle 20 and hence through gears 27, 28 to a spindle 29 which drives through a large wheel 37 and pinion 36, a central spindle 35 on which is a long pointer 38. A pinion 46 drives through reduction gear 45, 47, 48 a hollow spindle 49 on which is a mediumlength pointer 50. A further reduction drive 51, 52 from the spindle 49 drives a hollow spindle 53 on which is a short pointer 54. The three pointers 38, 50, 54 move over scales 39a, 39, 55 of pressures of which the scale 39 represents 0 to 10 inches, the scale 39a tenths of an inch and the scale 50 up to 30 inches. An annular wheel 26 having a seating on the frame member 25 carries a marker 56 bent over to read against the scale 39a. It may be adjusted by pressing in a knob 62 against its spring 67 to engage gears 65, 68 to drive through gear 69, spindle 70, and gear 72 the annular gear 26. A crown wheel 74 on spindle 70 through gear 60 drives a counter visible through a window 59. The last two digits of the counter always agree with the reading of the marker 56 on scale 39a. By manually operating knob 62 to set the marker 56 to a pressure desired to be maintained in flight, the instrument may be used as a level flight indicator by maintaining pointer 38 in coincidence with the marker 56. The reading of the instrument will vary during flight, but when the landing place is reached, the pointer 38 will coincide with marker 56. Specifications 415,458 and 438,137 are referred to.

Title: Improvements relating to metal structures
Inventor: SLABBERT ELDON STANFORD
IPC: E04H7/06
Filed: 1958-05-16
Abstract: 927,440. Tanks. JOHN THOMPSON (WOLVERHAMPTON) Ltd. Aug. 17, 1959 [May 16, 1958], No. 15854/58. Class 69 (1). A method of locating and maintaining in position a ring of metal plates around the periphery of a metal structure comprises locating the plates around the structure, pressing the ring closely around the structure to cause the plates to adopt their desired position thereagainst, determining the gap between the ring and the structure at a plurality of locations over the area of each plate, rejecting and replacing any plates the gaps beneath which either vary beyond acceptable limits or are greater than an acceptable limit and re-assembling the ring and securing together the individual plates in the ring so that on release of the pressure the plates remain in the desired position. The measurement of the gap between the ring and the structure may be effected by electromagnetic depthmeasuring apparatus which provides a direct indication of the gap dimension as a function of magnetic flux. Alternatively, the plates may be subjected to vibration for example by electromagnetic means and an instrument used which is capable of responding to this vibration over predetermined areas at the plurality of locations and of indicating the gap at these areas. In a further alternative, a plurality of apertures are formed at spaced-apart locations in at least one of the plates prior to location thereof around the structure. The thickness of the plate at each aperture is accurately measured and after location of the plates around the structure accurate measurement is made at each aperture of the distance between the outer surface of the plate and its supporting surface on the structure so that at the location of each aperture the size of the gap between the inner surface of the plate and the supporting surface on the structure can be determined. The thickness and the distance may both be determined by a depth gauge. The apertures may be located at regular intervals along each of a plurality of parallel rows on each plate of each layer. Specification 848,439 is referred to.

Abstract: 582,115. Rotary valves. BRIGGS MANUFACTURING CO., and GERNANDT, W. G. Aug. 21, 1944, No. 15922. [Classes 7 (ii) and 7 (vi)] An internal combustion engine has a cylinder head carrying a conical rotary valve with bearing rings 75, 78, interposed between the valve and its bearing wall and extending into a recess in the valve or wall. The valve which has a stem 26 is driven from the crank shaft through a vertical shaft and bevel gears is disposed in a cylinder head member 28 which is screwed at 30 to a second head or mask member 29 screwed to the cylinder 22. The member 29 terminates in a throat portion 32 opening into the combustion chamber 34 of the rotary valve, and its lower surface is shaped to conform to a conical domed portion 23a of the piston. The stem 26 of the valve is hollow and is closed by a plug 50, to seal off a cavity 49 which may contain metallic sodium or other coolant. The valve has a single port 59 adapted to register successively with intake port, spark plug at 61 and exhaust port. Preferably fuel injection is employed. For lubrication, an oil supply passage 70 leads through port 68 to a bushing 67 forming a bearing for the hub of driving gear 39 the gear hub having a groove 73 extended at 74 so that at every revolution of the valve oil is supplied to a port 69 in the bushing leading to a passage 71 which supplies passages 72 leading to the upper and lower bearing rings which are both free to float in their recesses with clearances at 76a, 79a. The floating mounting permits rotation of the rings during running at about half the valve speed thus reducing friction losses. Each bearing ring has zig-zag oil grooves 80, 81, Fig. 4, on the outer and inner surfaces respectively the grooves being connected at the cross-over points by cross-drilled holes 82. The areas between the bearing rings are relieved so as to confine the bearing surface to the rings.

Abstract: 586,608. Resilient mountings. NORMAN, J. W. LA F., and WRIGHT, C. S. Aug. 21, 1944, No. 15970. [Class 108 (iii)] A resilient mounting for machinery, instruments &c. comprises a weight-supporting part consisting of a substantially frusto-conical annular or recessed rubber or like, block c having main bearing surfaces c<1> arranged out of alignment axially and transversely and a secondary bearing surface c<2> adapted to bear against a supporting surface e under loads greater than normal, the surface c<2> being in the form of a sharplydefined frusto-conical portion of the outer surface of the block c adjacent the smaller end thereof and of greater divergence than the remainder of the outer surface. As shown, a machine b is supported on a base a by the block c, the bearing surfaces c<1> of which are bonded to a flanged metal frame d and to a centrallyspigoted bearing plate e through which extends a securing bolt f. A flanged rubber shock ring g, which may have a retaining plate h, may be mounted on a sleeve i abutting the spigot-of the plate e. The block c is stressed mainly in shear by axial load until the surface c<2> encounters the bearing plate e when the rubber is stressed in compression. Under normal axial load the spigot of the plate e enters the central aperture of the frame d so that the block resists heavy lateral loads by compression as well as shear. Lateral shock loads are also resisted by the rubber ring g which is compressed when it encounters the surrounding wall of the hole -in the machine b or base a, and the flange g<1> of the ring is compressed by axial loads in a direction opposite to that of the normal load.
