Title: Illuminated mirror compact
IPC: A45D42/04
Filed: 1980-07-01
Abstract: An illuminated mirror compact (1), Fig. 3, has an outer casing formed by two pivoted together half-shells (2, 3) and an intermediate member (6) mounted on the same pivot. The intermediate member (6) has integral ribs (9, 10) thereon defining a battery compartment (11) and lugs (12) for locating bulb holders (16) for bulbs (15).

Title: Conveying Assembly
IPC: A01C11/02
Filed: 1981-02-26
Abstract: A conveying assembly e.g. for use in a transplanter, in which inclined or roughly vertical belts are used to convey individual block-embracing portions detached from a bandolier of such blocks to a planting location where they are released. Where roughly vertical conveyor belts 133 are used, these are designed to embrace the blocks making additional support unnecessary. Where inclined belts 204, 205 are used (Figures 6 and 8), a support belt 202 or equivalent item is provided between two side belts which grip the blocks and prevent them sliding or tumbling down the support. In both cases, the belts are preferably arranged to compensate for the forward motion of the transplanter so as to encourage the released blocks to fall vertically, <IMAGE>

Title: Electrical heating element
IPC: H05B1/02
Filed: 1981-05-07
Abstract: An electrical heating element comprises an outer metal sheath (12) surrounding a wire heater (14) embedded in electrically insulating thermally conductive material (15) such as magnesium oxide. A cut-out is located within the sheath and is sensitive to the temperature of the heating element so as to interrupt the supply of current to the wire heater when the heating element reaches a preselected temperature. The cut-out may be a self-resetting cut-out having first and second normally closed contacts (26, 28) and a bimetallic device (24) operable to open the contacts when the preselected temperature is reached and to close the contacts when the temperature of the heating element falls below the preselected temperature. Alternatively, the cut-out may be a single action cut-out such as a heat fuse or an arrangement comprising two contacts joined together by a material, such as solder, which melts when the preselected temperature is reached to allow the contacts to open under the influence of resilient means. <IMAGE>

Title: Turbine control and protection system
IPC: F01D17/18
Filed: 1981-06-29
Abstract: A turbine control and protection system includes one or more control valves (52) and an emergency shutdown (start-up) valve (51) in a line carrying a working fluid to the turbine.

In addition to providing emergency shutdown when the turbine speed exceeds a set value the controllers may be energised to stop turbine operation in response to external signals. Checking means are provided enabling tests of operation of the system to be carried out without effecting the operation of the turbine. In the event of failure of one controller, the second can take over its function. <IMAGE>

Title: Tracking control system
IPC: G11B5/592
Filed: 1982-02-24
Abstract: A record medium, such as a tape, having skewed record tracks which are scanned by a transducer, is commanded by means of a jug wheel (16) to be transported at a speed and for a distance which may be arbitrarily variable. While the record medium is moved, successive record tracks are scanned by the transducer, and the phase difference between the scanned track and the scanning trace of the transducer is detected at (42). The speed at which the record medium is transported is derived from the command; and this speed is adjusted at (23) as a function of the detected phase difference. <IMAGE>

Title: Copying machine having variable magnification
IPC: G03G15/04
Filed: 1982-03-16
Abstract: A copying machine includes mirrors 6,7 which are moved during scanning of an original to be copied, and a zoom lens system 8 which is moved to alter the magnification of the copy image relative to the original, the regions of movement of the mirrors 6,7 and the lens system 8 being overlapped. In order to prevent a collision between these components, a detector 22 is mounted on a supporting frame 24 which moves synchronously with the lens system 8 and is actuated by a protruding piece 29 in the event that the mirrors 6, 7 approach the lens system 8 too closely, whereupon a drive for the mirrors 6, 7 is de-energised. In the event that the mirrors 6, 7 overshoot the position wherein the detector 22 is actuated, a protrusion 28a comes into engagement with a stop lever 23 mounted on the supporting frame 24 so that the stop lever 23 absorbs the impact.

Title: Conveying of bulk materials
IPC: B65G53/46
Filed: 1980-09-24
Abstract: Apparatus for conveying bulk granular material includes a pipeline (39) into which are connected a plurality of material feed members (36, 37). Each material feed member has a material inlet valve (41) and a material outlet valve (55) both of which are closable to prevent passage therethrough of both material and compressed gas. The apparatus is provided with means (71, 73, 75, 76) for feeding compressed gas to each material feed member in order to assist the discharge of material into the pipeline. The opening and closing of the valve is controllable so that at least one of the material feed members may be filled with material while at least one other of the material feed members is discharging material into the pipeline. A method for conveying bulk granular material is also described.

Title: RF signal receiver with phase- locked loop demodulator having variable bandwidth means
Inventor: SCHOTZ LARRY A
IPC: H03D3/24
Filed: 1982-06-15
Abstract: An FM receiver apparatus includes a frequency tuner and a phase-locked loop demodulator having a loop amplifier filter means for recovering of the modulated signal. The phase-locked loop detector includes a high quality voltage controlled oscillator (9) driving a tuned signal phase comparator (8) connected to a loop filter (10) which includes an active loop amplifier. The output of the filter is connected to drive the voltage control oscillator. The loop filter serves to set the bandwidth of the demodulation in accordance with the amplifier gain, the resistance capacitance filter components and the like. The loop filter includes a fixed capacitance (11) establishing a large signal bandwidth. A second fixed capacitor (21) is connected in series with FET transistor (22) in a series branch connected in parallel with the fixed bandwidth capacitor (11). An RF signal signal amplitude detector (24, 25) actuates the FET transistor to reduce the bandwidth of the phase-locked loop demodulator with the RF signal such that the loop filter pass-band tracks the tuner pass-band characteristic, particularly when a weak signal is received. <IMAGE>

Title: Compact bogie for three axle fifth-wheel tractor units
Inventor: MANNING WALTER
IPC: B62D61/10
Filed: 1982-07-22
Abstract: This invention arranges the wheels on the second and third axles of a three axle fifth-wheel tractor in such a way as to allow the wheels to overlap and form a close coupled compact bogie. Single wheel and tyre assemblies are used on all axles with the third axle track lying inboard of the second axle track. This configuration allows the fifth-wheel coupling king pin centre to be pitched further forward from the rear end of the vehicle than currently achievable on conventional two and three axle tractor units. The single wheels fitted to the second axle and also provide for a wide spread suspension system adjacent to the fifth-wheel mounting. Mudguard shaping and wheel coverage provides for anti-spray features. Low axle weights provide for low road damage rating. <IMAGE>

Title: Three-input binary adder cell with high-speed carry propagation
Inventor: LEROUGE CLAUDE PAUL HENRI
IPC: G06F7/503
Filed: 1982-10-08
Abstract: A binary adder cell with high- speed carry propagation for three input variables (A and/or A, B and/or B and C or C) and two output variables (R or R, and S or S), produced in accordance with MOS transistor integrated circuit techniques is described. A fast input receives a binary carry element (C or C), and two other slower inputs each receive one of the two other input data elements (A and/or A, B and/or B), these generally being received before the binary carry data. The interval of time between the arrival of these two data elements and the arrival of the carry is used to form the intermediary variable M = A (+) B and its complement M with the assistance of an intermediary calculation circuit which receives these two input data elements, in such a way that at the instant carry C or its complement C arrives, it is necessary to carry out only the following types of calculation: R = AM + CM or R = AM + CM and S = CM + CM or S = CM + CM. <IMAGE>
