Title: Electronic timepieces
IPC: G04G9/00
Filed: 1975-04-21
Abstract: 1486714 Electronic timepieces DAINI SEIKOSHA KK 21 April 1975 [22 April 1974(2) 24 April 1974] 16382/75 Heading G3T An electronic timepiece has an electro-optical time display part of which is digital and at least one of the hours, minutes and seconds display sections comprises electronic display elements arranged to provide a dynamic analogue display. In an embodiment Figs. 1 and 2, the seconds display comprises a ring of LED's. In an embodiment Figs. 6a, 6b (not shown) every fifth display diode comprises GaP and emits green light while the other diodes comprise GaAsP and emit red light. The green diodes have a higher threshold voltage and their refusal to light up gives a warning of end of useful life of the timepiece battery. Flashing of the illuminated diodes is effected by a transistor T, Fig. 2, controlled by an output "C" of a frequency divider DIV. In the embodiment Fig 2 and Fig. 2A (not shown), if it is desired to know the time to seconds a manually operable switch S1 in an electronic switching circuit is closed whereupon the hours and minutes appear digitally and L.E.D's - Do to D 60  are sequentially illuminated until the actual time counted by seconds counter 1 is reached and the appropriate diode flashes until turned OFF. Thus assuming S1 is closed when the time is 12 hours 30 minutes and 20 seconds as in Fig. 1, a switching circuit S2 is caused to pass pulses from an output a of a frequency divider DIV to clock a shift register 14 and a counter 4. In addition a data generating circuit DG applies shift pulses to input D of the shift register 14 so that it starts shifting simultaneously with the commencement of counting by COUNT 4. The register has sixty output terminals the outputs from which sequentially drive light-emitting diodes in a display 16 via a driver 15. When the content of counter 4 becomes equal to that in counter 1 the Q output of a comparator COMP opens S2. Consequently clockpulses to counter 4 and register 14 are stopped and the register stays which its content at 25. In this state diode D 24  is lit and is caused to flash by driving a transistor T from the output c of the divider DIV. The Q output of the comparator also triggers a monostable multi-vibrator M which produces a pulse resetting the counter 4, register 14 switching circuit Sl and a flip-flop (f 2 ) at the output of the comparator so that the flashing diode is extinguished. Instead of L.E.Ds, the display may comprise liquid crystal, electro-chromic, EGCL (electrogenerated chemical luminescent) or PLZT (ceramic material including P b -T i O 2 , P b Z r O 2 , La) elements. An arrangement Fig. 5 (not shown) is used to indicate elapsed time.

Title: Improvements in or relating to gear-hobbing machines
IPC: B23F5/22
Filed: 1929-05-30
Abstract: 331,343. Brown & Sons (Huddersfield), Ltd., D., and Reid, J. M. May 30, 1929. Gear-cutting.-In a gear-hobhing machine the hob table together with the hob-rotating and feeding mechanism, is adjustable about the horizontal axis of a worm gear from which the rotary and feeding motions are derived. The hollow body casting 10, whose base forms a sump for the cutter lubricant is provided with guides 11 for the work table slide 12 and with a circular seating 13 on which the hob table is adjustable, the setting being indicated by a scale 12<1>. The hob table carries guides 15, 15<1> for a slide 16 which is fitted with supports 18 for the hob spindle 17 carrying the hob 20. A worm shaft 26 coaxial with the arcuate seating 13 is connected to the hob-spindle through worm wheel 24, shaft 23, and spur gears 21. The shaft 26 is also connected to one side 27 of spur wheel differential whose other side is connected through a shaft 30 and change gears 31 to the spindle 32 of an electric motor. The shaft 23 is connected through clutch 34 and change gears 35 to a screw 36 which traverses the hob slide 17 to feed the hob tangentially of the blank. Further change gearing 37 connects the feed screw to a shaft 38 which drives the differential casing to compensate the blank rotation for the hob feed. The clutch 34 may be automatically tripped when the tangential feed is completed and the hob slide may be returned either by hand rotation of the shaft 36 or by power. A shaft 41 driven by change gearing 43 carries a splined wom 42 for driving the work table 19 which is fitted with a stand 19<1> carrying the blank and is mounted on the slide 12. Adjustment of the work table is effected by means of a screwed spindle 44 carrying a hand wheel 46, pinion 48, and a disc. 47 graduated in hundredths and thousandths of an inch. A pinion 49 carried by the disc 47 engages the pinion 48 and also a pinion 50 mounted on a second graduated disc 51 and having one tooth more or less than the pinion 50, so that a complete rotation of the screw moves the second disc through a distance representing two tenths of an inch.

Abstract: 837,185. Glass cutting apparatus. AMERICAN WINDOW GLASS CO. May 23, 1958 [May 31, 1957], No. 16618/58. Class 56. A glass cutting apparatus for making a transverse cut across a vertically rising sheet of glass has a slip clutch connection between power and cutting elements so that more than normal resistance by the glass automatically produces stalling. Fig. 3 shows the cutter component in side elevation. The cutter trolley 38 comprises a wheeled trolley A, a double acting pneumatic propulsions motor B mounted thereto at the top and a double acting pneumatic cutting cylinder C with cutter D operating on glass sheet 10, the cutter trolley 38 moving along the monorail 26 and extension rail 74 on rollers 60 and 73 respectively. The slip clutch connection comprises, firmly mounted to the rotor shaft 110 of propulsion motor B, a friction wheel 112 which in the driving position bears lightly, as a result of the pressure produced by the action of coil spring 102 which through a lever system pivots motor B clockwise on the axis of the mounting trunnion 90, on the upper roller 60. An increase over the normal cutting resistance causes friction wheel 112 to spin ineffectively on its axis. Specifications 725,894 and 795,836 are referred to.

Title: Improvements in hydraulic pumps and motors and hydraulic power transmission devices
IPC: F01B3/00
Filed: 1950-07-05
Abstract: 702,596. Hydraulic pumps. BORG-WARNER CORPORATION. July 5, 1950 [July 15, 1949], No. 16778/50. Class 102 (1). [Also in Group XXIX] In a hydraulic pump or motor of the type comprising a cylinder block having an annular series of cylinders and ports therein co-operating with a ported valve member, the flow of pressure liquid to and from the cylinders' being controlled by relative rotation between the valve member and the cylinder block and the consequential relative movement between the co-operating ports in these parts, the ports in the valve member are arcuate in outline and each comprises an intermediate portion of substantially uniform width merging immediately at its opposite ends into uniformly tapered end portions of substantial arcuate length, these end portions and the intermediate portion of each port being so dimensioned that the volumetric rate of flow through the ports is at all times approximately proportional to the velocity of the piston reciprocable in the associated cylinder. The Figures show a revolving cylinder swash plate type motor forming part of an hydraulic transmission. The supply of liquid to and from cylinders 20 is controlled by rotation of the cylinder block 21, cylinder ports 22 co-operating with inlet and outlet ports 50, 51 in a stationary valve plate 43. The ends of each port 50, 51 comprise tapered extensions 50a, 51a as shown which ensure that pressure is applied gradually and released gradually and that there is no undue increase of pressure in each cylinder as the piston approaches the end of the. working stroke. It is stated that the amount of taper of the extensions can be calculated to some extent but the final design must be worked out by experiment. In order to enable the inclination of the swash plate to be adjusted even though a port 22 is in a position in which it registers with the part of the manifold plate between the inlet and outlet ports, each cylinder contains a bore 66 which registers in this position of the cylinder port with a slot 67 connected to the sump. The inclination is variable by turning a shaft 37. A constant velocity universal joint 31 is connected between the shaft 14 and the swash plate 32. The pressure in each cylinder acts on an area 22a which is greater than an area 22b and thus urges the cylinder block into contact with the manifold plate. Grooves 22c are connected to the sump by a groove 22d. A gear pump or other pressure generator supplies the motor, the outlet side of the pump being connected to a chamber 40 and the inlet side being connected to a chamber 41.
