Patent GB-740845-A (GB)
Abstract: 740,845. Turning-gear; lubricating. UNITED AIRCRAFT CORPORATION. June 23, 1953 [July 5, 1952], No. 17356/53. Classes 7(2) and 7(5) . In a power plant starter comprising a rotatable member 124 embodying clutch teeth 122 and fixed on a shaft 110 that is. connected to the power plant, a cylindrical gear member 84 adapted to be axially moved to engage its clutch teeth 120 with teeth 122, and a sleeve 102 threaded within the gear 84, there is provided a spring 106 to frictionally restrain the sleeve against rotation and cause relative axial movement of the gear 84. The starter turbine rotor 28 which is driven by compressed air or other gas is integral with a shaft 32 that is surrounded by a sleeve 40 having teeth 44 meshing with a gear 46 which together with another gear 54 is mounted upon a shaft 48; gear 54 engages a gear 58 upon a countershaft 60. The starter includes two of each of members 46, 48, 54, 58 and 60 although only one of each is shown. Each shaft 60 which embodies helical teeth 80 meshing with similar teeth 82 on the gear 84 is loaded by springs 90 to permit axial movement thereof and hence equalization of load and wear between the two gear trains; gear 84 and sleeve 102 are urged into the position shown by a spring 104. When the shafts 60 are rotated by the turbine through the above described reduction gearing, and clutch teeth 120 and 122 begin to engage the relative angles of the helical teeth are such that under load gear 84 will tend to move rightwardly; upon full engagement of teeth 120, 122 the shaft 110 will drive a gear 134 adapted to engage the power plant driving shaft. The teeth 120, 122 are engaged and disengaged in dependence upon the turbine speed and hence the control of gas to the turbine since as the power plant speeds up the gas supply is cut off. Seals 150, 152 in the starter casing 70 provide for gas tightness of the latter; the casing also contains lubricating oil into which dip gears 46 and 58 and a splasher plate 160. The bearings supporting shaft 32 are pre-loaded by a spring 162.

Patent GB-2002541-A (GB)
Title: Electronic programming device for engine powered line marking machines
IPC: G05B19/07
Filed: 1978-07-11
Abstract: An electronic programming device for an engine powered line marking machines uses a signal derived from the engine electrical system to derive all the power necessary for operating the paint spray valves and for sequencing the operation of the valves. This is achieved by connecting a rectifier 12 to a part of the engine electrical system which develops an ac component e.g. the ignition system and rectifying part of this component to produce dc pulses. A power unit 10 stores these pulses in a capacitor to produce the power for the valves and a timing pulse generator 18 produces a timing signal proportional to engine speed. A timing circuit 19 refines the signal to take account of gear ratio and to produce a greater number of pulses for each timing pulse which are then proportional to road speed, and a sequencing circuit 31 uses these pulses to programme the valves to provide the appropriate lengths of marks and spaces. <IMAGE>

Patent GB-2004165-A (GB)
Title: CMI encoder
IPC: H04L25/49
Filed: 1978-09-07
Abstract: In a CMI encoder the output OR gate is replaced by a D-type bistable which is re-set by short pulses, derived from the clock pulses supplied to the coder after they have first been gated with this data. The bistable acts as a clock OR gate and removes jitter. In this circuit configuration the D-type bistable only needs to operate at the data rate and not at twice the data rate. <IMAGE>
Patent GB-2006551-A (GB)
Title: Lamp Holders
IPC: H01R33/46
Filed: 1978-10-13
Abstract: A holder for a lamp bulb 4, e.g. for a vehicle interior light, has a U- shaped contact spring (8, 9) with one limb (9) mounted on a housing or contact carrier (2) of the light and the other limb (8) abutting the base contact (10) of the bulb (4). A spacer element (14) on at least one of the two limbs determines the minimum spacing between the two limbs and thereby limits the deflection of limb 8 to prevent over-insertion of bulb 4 which could otherwise result in a short circuit between limb 8 and contact 15 on the lamp cap. <IMAGE>
Patent GB-2006434-A (GB)
Title: Switchable Depth of Focus Pulse-Echo Ultrasonic-imaging Display System
IPC: B06B1/06
Filed: 1978-10-17
Abstract: The invention permits changing of the effective depth of focus in the system to which the invention relates by providing a transducer unit (10) having a central section (18/16) and a separate surrounding annular section (20/16) which are effective in detecting different parts of the signal portion of the reflected beam, the central section detecting a part returning through only a small portion of the lens aperture and the annular section detecting the part returning through the remainder of the aperture. Switching (12) is coupled to the two transducer sections (18/16, 20/16) for selectively displaying either only the parts detected by the central portion or both that part and the part detected by the annular portion together. The switching can be used to select only the center portion (providing a greater depth of focus) for initial setting up prior to selecting both portions for a high resolution display of a target area in a desired plane with reduced depth focus. Alternatively the switching may be time-controlled relatively to the outward and return journeys of the transmitted pulses to provide maximum resolution within a small focal region of a relatively large aperture lens, using both center and annular portions of the transducer, while structure under examination but outside of that region can be displayed at lower resolution using only the center portion. <IMAGE>

Title: Gas Control Devices
IPC: F23N5/06
Filed: 1978-11-02
Abstract: A gas control device includes a member (31) which is adjusted by temperature-responsive displacement means (46) to reduce gas flow as temperature rises, e.g. in a gas oven. The valve member is slidably mounted on a carrier (27) and in axial abutment with an adjuster (28) threadedly mounted on the carrier for axial adjustment therealong to vary the gas flow/temperature response of the device. The carrier (27) is separate from the displacement means (46) but is biassed into contact therewith by a leaf spring member (42). The carrier, valve member and adjuster can be a separate pre- assembled unit. The device is associated with a manually-actuable rotary play on/off valve 12 through which the adjustment of the adjuster (28) is effected. <IMAGE>

Title: Time division multiplex telephone exchange
IPC: H04Q11/04
Filed: 1978-11-14
Abstract: In a TDM telephone exchange, it is necessary when setting up calls to take account of the time taken for a PCM code combination to negotiate the exchange's switching network. A path supervision device, addresses the input and output ends of that connection, and stores input and output PCM combinations. Each input combination is compared successively with all output combinations, and from the times at which identity is detected, the shift in time caused by the passage through the network is determined. Any variation in this shift causes:     (a) an evaluation of the new shift, and (b) the recording of data representing the new shift plus the time at which the change occurred.   Supervision of one connection ceases either when an allotted time has elapsed, or after a preset number of unsuccessful identity tests. The recorded data are analysed and a statistical reading is sent to the central control.
