Filed: 1965-10-07
Abstract: 1,085,452. Change-speed control; friction clutches. FORD MOTOR CO. Ltd. Oct. 7, 1965 [Oct. 28, 1964], No. 42534/65. Headings F2C and F2D. A vehicle transmission comprises a planetary gear 112 having a sun 120 common to a planetary gear 142, Fig. 1C (not shown), two clutches 96, 98 and 106, 108, two friction brakes 70 and 170, 172, Fig. 1C, and a one-way brake 160, Fig. 1C, the clutch 106, 108 being applied by piston 126 through Bellleville washer 130 and clutch 96, 98 by a stepped piston 80 having two actuating chambers 76, 78. Fluid pressures to the two clutches act on opposite sides of a shuttle 222, Fig. 2 (not shown), spring-biased to connect a feed port 228 of chamber 76 to exhaust port 220 (N.B.-Fig. 1B is approx. a V-section through the transmission so that ports 220, 228 are adjacent each other). For direct drive when both clutches are engaged, fluid pressure from passages 206, 208 passes via passages 214, 212 to act equally on either side of shuttle 222 so that the spring keeps the shuttle in a position to vent chamber 76 so that clutch 96, 98 is applied by pressure in chamber 78 only. For reverse, no pressure acts on clutch 106, 108 and pressure in passages 208, 212 for clutch 96, 98 acts on shuttle 222 to move it against the spring to open port 228 to passage 212 whereby both chambers 76, 78 are pressurized for stronger clutch engagement for higher torque transmission. The pressure fluid is supplied to the clutches through a manifold 196, Fig. 1C, and is modulated by a governor valve 198 on the output shaft. The carrier 114 of planet gear 112 and the ring 144 of planet gear 142 are splined to the output shaft; the common sun 120 may be braked by brake 70 or driven through clutch 96, 98, the ring 110 of gear 112 may be driven through clutch 106, 108; and the carrier 146 of gear 142 is connected to a one-way brake 160 and to a friction brake 170, 172. For one-way low-speed, clutch 106, 108 is engaged and output shaft 12 is driven through carrier 114 and ring 144, the two trains being compounded; for continuous two-way low-speed with upshift prevented, brake 170, 172 is also engaged. For intermediate, brake 70 and clutch 106, 108 are engaged, the sun 120 being anchored, the front train acts alone, and the shaft 12 is driven through carrier 114, the one-way brake 160 overrunning. For high speed, direct-drive, both clutches 96, 98 and 106, 108 are engaged, the sun 120 being locked to ring 110. For reverse, clutch 96, 98 and brake 170, 172 are engaged and shaft 12 is driven through ring 144, the rear train acting alone.

Abstract: 1444668 Sealing porous metal objects GENERAL TIRE & RUBBER CO 4 Oct 1974 [18 Oct 1973] 43142/74 Heading B2E A method of sealing the surface of a porous metal object with a thermosetting resin comprises, (i) heating the porous metal object to an elevated temperature above the curing temperature of the resin for sufficient length of time to raise the temperature of the gases within the pores of the metal object substantially to the elevated temperature, (ii) applying to the surface a dry powder comprising a major proportion by weight of resin and not more than 20 wt % filler (e.g. talc), (iii) reducing the temperature of the object to the curing temperature of the resin whereby gas in the porous metal object cools and contracts to draw in the resin, and (iv) maintaining the object at the curing temperature until the resin cures to form a coat which traps the gas in the pores. The sealed object may then be primed with adhesive and bonded to rubber or coated therewith. Generally the curing temperature is from 50 to 150‹F and the powder may be applied by electrostatic spraying, fluidised bed or electrostatic fluidised bed. In Examples (1), (2), metal objects are electrostatically sprayed with blue epoxy resin powder containing a filler then, after the curing steps, are futher spray coated with two coats of a solution of epoxy adhesive from which the solvent was evaporated, before being vulcanisation bonded to an elastomer, (3) as in (1) but a green epoxy resin powder was substituted for the blue, (4) as in (1) but without the filler. A list of natural and synthetic elastomers, suitable for bonding is given.

Abstract: 1,207,123. Reproducing coloured originals. KODAK Ltd. Sept.29, 1967 [Sept.30, 1966], No.43912/66. Headings G2A and G2C. [Also in Divisions H3 and H5] In photographically reproducing coloured originals, the light source is derived from thee cathode ray tubes having screens which fluoresce in different colours, the three light beams being synchronized to scan the original in unison. As shown, light from the tube 10, passing through a filter 12, falls on a dichroic mirror 13 which reflects blue light and transmits green and red. Light from tube 14 passing filter 16 falls on dichroic mirror 17, which reflects green light and transmits red. Tube 18 and filter 20 provide red light. The light from the three tubes is combined in a scanning raster which passes through a field lens 21 on to the original transparency 22, and is imaged by a lens 23 on to the lightsensitive copying material 24. Some of the light is diverted by a semi-transparent mirror 25, and is divided by a dichroic beam-splitter 27 into blue, green, and red components which are received by respective photo-multipliers 28, 29, 30. The separate signals are converted to logarithmic values in amplifiers 31, 32, 33, and then matrixed to correct for unwanted dye absorptions, fed to antilog amplifiers 34, 35, 36, and matrixed again to correct for lack of negative lobes due to the sensitizing dyes. The signals are now fed to gamma correctors 37, 38, 39 for contrast correction, and then via polarity inverters 40, 41, 42 back to the respective cathode ray tubes. A ground glass screen may be placed at the copying station 24 for preliminary inspection of the image.

Abstract: 1459350 Camera shutters SEIKO KOKI KK 10 Oct 1974 [11 Oct 1973] 43955/74 Heading G2A A camera shutter mechanism comprises a release member 3 adapted to be moved out of a rest position, Fig. 1, to operate shutter-opening means 1, member 10 carrying an armature 10b and adapted in an operative position, to operate shutter-closing means 2, and an electromagnet 11 adapted, when energized, to maintain the member 10 out of the operative position. The mechanism operates as follows:- depression of the member 3 closes a switch 12 in a circuit, see Fig. 3 (not shown) which comprises a timing switch (13) and a photo-cell (16), and which is described in Specification 1215533, so that the electromagnet is energized and holds the armature 10b down, as in Fig. 1; simultaneously a member is moved clockwise by a spring 9 until a pin 8b contacts a recess 10c in the member 10 which is then free to move clockwise until it contacts the means 2, once the electromagnet is de-energized by operation of the timing switch (13). With the armature 10b held down by the electromagnet, the member 3 can be fully depressed to operate the means 1, but if for any reason the electromagnet is not energized the member 10 is moved clockwise immediately and an abutment 8a engages a recess between two projections 3a, 3b to prevent operation of the means 1. In another embodiment, Fig. 4 (not shown) minor constructional modifications are described.

Title: Electrical ratio control apparatus
IPC: D21F7/02
Filed: 1966-10-03
Abstract: 1,137,938. Control of several A.C. motors. BORG-WARNER CORP. 3 Oct., 1966 [5 Oct., 1965], No. 44128/66. Heading H2J. In a ratio control system for regulating the speeds of a plurality of motors 10-40 at different stations, the ratio of motor speeds between two adjacent stations may be changed without altering the previously established speed ratios between the remaining stations. A master oscillator 12 supplies timing pulses to digital stages 14-22 each of which controls the ratio between the motors of that stage and those of the succeeding stage. The stage 14 passes pulses to master inverter 26 and to stage 16 at the second station. Inverter 26 regulates slave inverters 28, 29, associated with motors 10, 11. The second stage 16 provides output pulses at a rate which is dependent upon the pulses received over lines 24, 27, to regulate the frequency of master inverter 32 for controlling slave inverter 33 and motor 20. The stage 14 comprises comparator 41 which sends a signal to master inverter 26 and a reset signal to counter 46 when voltages V1, V2, are equal. The counter 46 includes count circuit 47, a circuit 48 for operating circuit 47 instantaneously as each pulse is received over conductor 24, and a gate circuit 49 which sends signals over a plurality of conductors 50 to a digital-to-analog converter 51. The value of voltage V2 depends upon the output of converter 51, whilst the value of voltage V1 is determined by divider network 54. Count circuit 47 is coupled to memory unit 61 which registers the number of pulses passed over conductor 24 to counter 46 before comparator 41 recognizes equality between voltages V1, V2. This number-denoting signal is applied to digital-to-analog converter 63 the output of which determines the voltage on line 27. As long as there is no equality between voltages V1, V2, counter 46 accumulates timing pulses from the master oscillator, the output of converter 51 increasing until the voltages become equal. Count circuit 47 is then reset to zero and an output pulse over line 25 regulates the frequency of the master inverter and the speed of the motors at the first stage. Potentiometer 15, which is connected to converter 63, controls the ratio between stages 14, 16, since the counters 46, 76, receive pulses at the same frequency, and the time at which voltages V3, V4, become equal depends upon the setting of arm 65. Similarly, adjustment of the position of arm 95 correspondingly governs the ratio between stages 16, 18.

Abstract: 970,988. Shock-absorbers. A. A. L. CHANEAC, and H. G. CHANEAC. Dec. 23, 1960 [Dec. 24, 1959; April 25, 1960; Dec. 1, 1960; Dec. 20, 1960], No. 44239/60. Heading F2S. [Also in Division B7] The rate of a vehicle fluid suspension unit comprising a cylinder 1 divided into two chambers at different pressures by a piston 4 is controlled by an adjustable pressure reducer 11 in fluid inlet duct 6 (Fig. 1) or 27 (Fig. 2). The fluid in chambers 2, 3 may be air (Fig. 2) or hydraulic liquid (Fig. 1). In the latter case springing is provided by compressed air in chambers 15, 16 separated by diaphragms 17, 18 from the liquid. In Fig. 1, height regulation is achieved by passages 7 and 13 in the piston 4 and passage 9 in the cylinder wall. When piston 4 falls too far pressure fluid passes through passages 7 and 9 from chamber 2 to 3 to raise the piston and when the piston rises too far pressure fluid passes through passage 13 from chamber 3 to outlet 10. Height regulation is achieved in Fig. 2 by piston 4 and passage 7 in the piston which open and close inlet 6 and outlet 10 as the piston position changes. In an alternative (Fig. 4) valves 8, 25 and 20 in the inlet and outlet ducts 6 and 10 and the piston are controlled by fingers 23, 26 and 21 to control the piston position and hence vehicle height. Each unit of a vehicle is provided with a drain cock 14 to facilitate repair of a puncture.

Abstract: 1355892 Electronic timepiece CITIZEN WATCH CO Ltd 25 Sept 1972 [25 Sept 1971] 44263/72 Headings G3R and G3T An electro-mechanical drive for a timepiece which includes a drive coil 20, comprises a signal source 102<SP>1</SP>, a multi-stage frequency divider 5, 10, 11, 12, a gating circuit 15, 16, 17 to control the output of the frequency divider and provide drive pulses of variable width, the width being increased by a discrete amount when the voltage induced in the drive coil 20, is sensed to have dropped below a predetermined value. The output from source 102<SP>1</SP> is fed through inverter 3 directly to one input of flip-flop 5 and through inverter 4 to the other input of 5. A number of similar flip-flops (not shown) are connected in cascade to reduce the frequency to 128 Hz at the input of flip-flop 10 to produce a final frequency of 16 Hz at the output of flip-flop 12. If the signal from coil 20 exceeds a predetermined level then amplitude detector 13 switches memory 14 to level 0 which allows the 128 Hz signal from the input of flip-flop 10 to be fed through switching circuit 30 and to one input of NAND gate 17, the other three inputs being 64 Hz, 32 Hz, 16 Hz from the appropriate dividers, and as a result the drive pulse produced has a width of 1/16 period and repetition rate of 16 Hz Fig. 7, (not shown). Conversely when the signal does not exceed the required level then memory 14 is switched to level 1 which causes the 64 Hz signal from the input of flip-flop 11 plus the 128 Hz signal from 10 to be fed through 30 to gate 17 and as a result the drive pulse produced is twice as wide i.e. # period. This restores normal amplitude to the drive circuit very quickly.
