Title: Improvements in or relating to fluid pressure control means for friction clutches
Inventor: BLAND ALBERT NORMAN
IPC: F16D43/14
Filed: 1958-12-30
Abstract: 940,384. Fluid-pressure servomotor control systems. AUTOMOTIVE PRODUCTS CO. Ltd. Dec. 22, 1959; [Dec. 30,1958; Nov. 27,1959], Nos. 40473/59 (Divided out of 938, 561) and 40474/59. Heading G3P. [Also in Division F2] The subject-matter of this Specification is similar to that described in Specification 938,561 but in the conduit to the power device there is included a solenoid-actuated three-way valve operated either by a manual switch or automatically when shifting the gear lever; the valve either connects the power device with the speed responsive valve or with the vacuum or pressure reservoir. In a modification, the conduit 48 to the power device 34 contains a valve device 91 comprising two closures 102, 103 actuable by a diaphragm 92, the closures being normally in the position shown; the upper closure 102 controls the communication between conduit 48 and another conduit 116, which as shown may be open to atmosphere 125 or to the vacuum reservoir 39 via two solenoid actuated actuated valves 112, 127. The conduit 116 has a branch 128 leading to a power device 129 and another conduit 132 from a chamber 117 in valve 112 leads to another power-device 133,both devices 129,133 acting oppositely on the engine throttle 131. A vacuum operated switch 134 is connected to conduit 116 and another switch 137 is mounted in the clutch and only closes when the driven plate 21 is running faster than the pressure plate 18. Upon initiating a gear change, a switch 136, in the gear lever knob e.g., is closed and the solenoid valve 112 is energized to apply suction to the diaphragm 92 thereby seating closure 103 and opening closure 102 to connect the device 34 to vacuum via conduit 116 and disengage the clutch; the switch 134 is also closed and the power device 129 reduces the throttle opening. Should the engine speed not fall sufficiently to bring the speed of the pressure plate below that of the driven plate then upon the opening of a switch 136 the device 134 is reconnected to atmosphere to re-engage the clutch; if the speed of the pressure plate falls below that of the driven plate, the switch 137 closes and solenoid valve 127 is energized to maintain the application of vacuum in the device 34 when the gear change is completed and the solenoid valve 112 is de-energized. Vacuum is also applied to power device 133 to open the throttle until the switch 137 opens and enables the clutch to re-engage.

Title: Optical systems for colour television cameras
IPC: G02B5/28
Filed: 1976-09-30
Abstract: 1533798 Three colour system CANON KK 30 Sept 1976 [7 Oct 1975] 40665/76 Heading G2J [Also in Division H4] A colour television camera has an optical system including dichroic mirrors 3, 4 which separate the light from an object O into a number, e.g. 3, of different wavelength ranges for respective pick-up tubes 5. To compensate for colour shading that would otherwise occur a filter assembly 12, 13 precedes the first mirror 3 met by the light from the object. The assembly includes a member whose transmission factor varies across its width for light of one of the wavelength ranges in correspondence with the variation of intensity across a beam of light derived from a uniformly white object. For example, the member 12 is wedge-shaped and partly absorbs green light. The other member 13 of the assembly is also wedge shaped, so providing a parallel-sided assembly, and may be transparent or may be a neutral density filter to compensate for luminance shading. Alternatively, member 13 may absorb blue and red light and member 12 be transparent or neutral density. The pick-up tubes may also receive bias light from a source 9 via the mirrors. The bias light path includes a diffuser 10 and a filter assembly 14, 15 similar to assembly 12, 13. The dichroic mirrors may be formed on the faces of internally reflecting prisms.

Abstract: 409,715. Ticket-issuing machines. BLACK, H. D., 39, St. James's Street, London, and WEBB, C. F., 24, Deane Way, Eastcote, Middlesex. Oct. 3, 1932, Nos. 27449 and 27450. [Class 106 (iii).] A key-operated ticket-issuing machine issues one or a multiple length of ticket strip through a rotary pin and slot drive, which may take the form of an improved Maltese Cross mechanism, the pin wheel of which is operatively associated with means for limiting the extent of rotation of the pin wheel in accordance with the length of ticket strip required. One of the keys 16, 17, 18 is depressed according to the length of ticket strip 15 required to be issued and this causes the depression of a stirrup 36 with an extension 37 having a pin 38 engaging a shoulder 40 in a push bar 41, bearing on a fulcrum pin 67, so that the bar is moved to the left and with it the pawl 42, knife 29 and double armed lever 45 pivoted at 46. The lower arm 47 of the lever 45 is thus moved to the right to rotate the bellcrank lever 34 and put the pinion 33, driven from the motor driven shaft 31 started by depression of a key, into engagement with the toothed wheel 23. The wheel 23 carries rollered pins 22 engaging slots 21 in a wheel 19 having projections 25 engaging with holes 26 in the ticket strip 15 passing over a curved guide plate 27 slotted to take the periphery of the wheel 19. The depression of a key 16, 17 or 18 correspondingly positions, as shown in Figs. 3 and 6, a stirrup 55, with finger 57 and pivoted at 54, to engage with a corresponding stop face 58, 59, 60 on a block 61 fast with a pinion 62 which, being revoluble on a pin 63 on the push bar 41, is in engagement with a toothed wheel 65 driven from the slot wheel 19 through a pinion 20. Upon the engagement of a stop face 58, 59, 60 with the finger 57, the wheel 65 causes the pinion 62 to be pushed downwards and with it the bar 41 which pivots about the pin 67 to rotate the pawl 42, the nose 43 of which is thus positioned in front of one of the teeth 51 on the wheel 23. This causes, firstly, the lever 45 to be rotated clockwise to allow the spring 50 to disengage the driving wheel 33 from the toothed wheel 23 to stop the feed of ticket strip 15, secondly the knife 29 to cut off the ticket strip, and thirdly the pawl 42 to be moved to the right to engage with a roller 68 and be restored to its normal position. The keys 16, 17, 18 are kept depressed by means of a detent until the completion of ticket feed, the parts then all returning automatically to their initial positions. Several ticket issuing units as above described may be accommodated side by side in a common casing and allocated to the issue of different classes of tickets. A modified form of Maltese Cross drive mechanism is shown in Fig. 1 in which the radial arm 3 on the shaft 1 carries a rollered pin 4 working in radial slots 5 in a disc 6 fast on a shaft 2 and integral with a disc 7 having concave recesses 8 engaging with a disc 9 fast on shaft 1 and disposed with disc 7 in a plane axially displaced from the plane of the disc 6. Specification 378,449 is referred to.

Abstract: 1,079,854. Single sideband modulator and demodulator circuits; multiplex signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 20, 1964 [Oct. 25, 1963; Aug. 26, 1964], Nos. 42230/63 and 34937/64. Headings H3Q, H3R, H4L and H4R. In a known circuit, a modulation signal S, Fig. 3, is fed in phase quadrature to two multipliers (modulators) M1 and M2 which are supplied with the same carrier signal C, and the outputs of the multipliers are fed to phase-shift networks PS3 and PS4 which introduce a further relative phase shift of 90 degrees. It is shown that if the outputs of PS3 and PS4 are combined additively or subtractively the lower or upper sidebands cancel leaving the upper or lower sideband as the output USB. A similar circuit may be used at the receiver to separate a wanted upper sideband signal from an unwanted lower sideband signal (or vice-versa), and in this case unwanted high frequency components in the outputs of the multipliers are suppressed by low pass filters, Fig. 4 (not shown). The multipliers M1 and M2 may be single plate or twin plate Hall effect devices. Frequency division multiplex systems. In a multiplex system a plurality of units as shown in Fig. 3 may be connected through individual auxiliary filters to a common output, Fig. 8 (not shown). According to the invention, Fig. 6 (not shown), the outputs of all the M1 multipliers are fed, if necessary through buffer stages, to a common unit PS3 and outputs of all M2 multipliers are fed to a common unit PS4, the final output being derived from the combining unit CC. In an alternative form of the invention, Fig. 9 (not shown), the odd channels share common units PS3, PS4 and CC and the even channels share similar common units, the outputs from the two combining units being fed to respective auxiliary multiplex filters.
