Title: Blind landing aid system
IPC: G01S17/02
Filed: 1970-01-09
Abstract: 1292876 Radio navigation; television THOMSON CSF 9 Jan 1970 [24 Jan 1969] 1277/70 Headings H4D and H4F In a blind landing system an aircraft 1, Fig. 1, raster scans a series of corner reflectors 2 along the edge of the runway with an infra-red beam 3. Reflections of the beam from the reflectors are received at the aircraft and produce corresponding runway outlining responses on a cathode ray tube, raster scanned in synchronism with the scanning of the infra-red beam. The infra-red beam is produced by a cyanide gas laser 10, Fig. 2, and is line scanned by a mirror drum 11. The frame scan is caused by a mirror 14 reciprocating under the control of a loudspeaker diaphragm 17 energized by a sawtooth wave generator 18. The reflected radiation is passed back by mirrors 14 and 11 and is mixed at semi-reflecting mirror 32 with part of the transmitted beam. Since the aircraft is moving with respect to the reflectors, the reflected radiation is doppler frequency shifted, and the mixing gives rise to a doppler beat frequency, which via infra-red detector 30 and frequency tracking receiver/detector 31 causes a bright up of the scan of cathode ray display tube 19. Generator 18 controls the frame scan of tube 19 whilst line scan sync. pulses are produced by a detector 27 detecting the light from source 26 as reflected by the mirror 11. To improve the sensitivity of the receiver/ detector 31, the doppler beat frequency signal is fed to a mixer where it is heterodyned with the output of a voltage controlled oscillator (Fig. 4, not shown). In a search mode, a sweep-generator sweeps the frequency of the oscillator until the I.F. output of the mixer becomes within the narrow bandwith of a frequency discriminator. When this is determined, the action of the sweep generator is locked, and the frequency discriminator output takes over the control of the oscillator. The reflectors 2 comprise a two-dimensional array of trihedral corner reflectors (Fig. 3, not shown).

Title: Improvements in and relating to driving gears for hose reels and the like
Inventor: LAMBERT ALFRED WALTER
IPC: F16L3/01
Filed: 1960-01-15
Abstract: 915,375. Toothed gearing. BROCKHOUSE & CO. Ltd., J. April 17, 1961 [Jan. 15, 1960], No. 1479/60. Class 80 (1). [Also in Group XXVIII] A hose reel 2 is rotatably mounted by bearings 31, 32 on a fixed hollow member 9 and is driven through reduction gearing comprising a sun gear 15, also rotatably mounted on the member 9, and a planet pinion 16 mounted on a shaft 18 which is supported by bearings 19, 20 within the reel 2 and may be locked relatively thereto in order to effect the drive. A chain sprocket 23 is secured to the sun gear 15 and is driven from an electric motor through chain gearing. The locking means comprises a ratchet-wheel 35 keyed to the shaft 18 and engageable by a pivoted pawl 36 integral with a cam 38 which is movable by a spring-pressed manually-operable lever 52. A pivoted lever 43 is engaged at one end by a tension-spring 46 which causes a roller 48, carried at the other end of the lever 43, to engage the cam 38. The lever 43 also carries a brake pad 51 adapted to engage a brake wheel 50 secured to the shaft 18 adjacent the ratchetwheel 35. In the condition shown in Fig. 5, the cam 38 prevents engagement of the brake pad 51 with the brake wheel 50 and the reel 2 can be driven clockwise by the motor for the purpose of winding the hose on the reel. For the purpose of winding by hand, the shaft 18 may be rotated in the opposite sense by a handle applied at its other end 22, the pawl 36 then ratcheting over the teeth of the wheel 35 and rotation of the sun-wheel 15 and sprocket-wheel 23 being prevented by a spring-pressed catch 55, Fig. 7, engaging an aperture 53 in the side of the sprocket-wheel 23. Unwinding of the hose is effected by pulling it from the reel. For this purpose the pawl 36 is disengaged from the ratchet-wheel 35 and the brake 51 is applied to prevent over-running of the reel. A slipping clutch may be incorporated in the drive and the toothed gearing may be replaced by belt or chain gearing.

Title: Multiprocessor computing systems
IPC: G06F9/46
Filed: 1971-01-13
Abstract: 1331866 Programmed data processor WESTERN ELECTRIC CO Inc 13 Jan 1971 [16 April 1970] 1618/71 Heading G4A A multiprocessor computer system allowing a plurality of programs to be running simultaneously has separate functions performed simultaneously. Each function is separated into discrete parts called tasks which use data sets with several tasks using the same set. The set may be a contiguous or non-contiguous sequence of stored logically connected data words. A task is not assigned to a processor until all the conditions required for its running, e.g. the processing of one or more other tasks, have been satisfied. A task assignment word has a conditional enabling bit for each task on which it depends and an absolute enabling bit set when all the conditional bits are set. When the absolute bit is set the highest priority word is chosen and the associated task is assigned to a processor. A locking function is then performed according to the program listed in Figs. 3, 4. The program Data Set Lock Manager DSLM uses two types of data sets (Figs. 1 and 2) not shown each comprising a plurality of words stored in memory a Data Set Lock Table DSLT containing fields indicating whether the data set is locked, whether it is read-locked or write-locked, fields containing the contents of a system clock, containing error control information, a counter or a pointer to a Task Lock List, and pointers to first and last Task Lock Lists waiting to lock the data set, and a Task Lock List TLL containing the information required to lock all the data sets a task requires. Fig. 3 shows a flow chart for LCKALL called when all precedents have been performed to lock all the data sets for a task LCKALL is entered at 100 and at 102 acesses the first word of the TLL associated with the task. If the first word or header is locked an error routine 106 is commenced since LCKALL unlocks the headers 126, 116 at the end of the routine. If the header is not locked a counter C1 is set to a value equal to the number of data sets to be locked. The counter is used to access a pointer from the TLL to the next data set to be locked and this is supplied to a LCKONE routine (Fig. 4). This sets a counter allowing accessing of a DSLT over a fixed period of time before an error is called in the event of the DSLT being locked. If the DSLT is not locked the remaining steps of the flow chart in Fig. 4 are followed. The flow chart of Fig. 3 is resumed at 114 and if the data step was not previously locked C1 is decremented 120 and the remaining data sets are locked. When all data sets are locked the TLL header is unlocked 126. Flow charts for an unlocking procedure are given (Figs. 5, 6, not shown).
