Abstract: 816,071. Road-vehicle spring-suspensions. METALASTIK Ltd. June 5, 1957 [July 11, 1956], No. 21482/56. Class 108(2) The invention relates to vehicle spring suspension systems comprising a fore-andaft extending beam 5 pivotally connected to the underframe or body 6. and on which is mounted a vehicle wheel 10, the two beams 5 being connected by a cross tie 8 near their outer ends, and a spring acting between each beam 5 and the underframe or body 6. According to the invention, each spring comprises an inextensible pivoted suspension link with resilient bushes 12, 15, about its pivots, in which the angular relationship of the link is varied by relative movement of the beam 5 and the underframe 6. The arrangement is such that under tare loading conditions, the load is carried by the bushes 12, 15, in torsion only, whereas deflection of the system to either side of the tare loading position, is resisted with increased stiffness due to the bushes 12, 15, becoming eccentric as compressive components on the bushes are brought into play. As shown, the cross tie 8 is flexible, and comprises an upper and lower flat strip. Its ends are of box construction and carry pivots 11 on which are mounted the respective rubber bushes 12. The latter are secured within respective metal sleeves 13 which are connected by parallel links 18, 18, to metal sleeves 16 secured to the respective rubber bushes 15. The latter are carried by respective pivots 14 which are rigid with a sub-frame 17 secured to the underframe 6. The sub-frame 17 is of flexible construction so that it will twist with the roll of the vehicle body. Diagonally disposed tie rods 20 connected between the links 18, are adjustable by means of respective turn buckles 21 to enable the rubber bushes to be pre-loaded. The vehicle wheels 10 may be resiliently mounted by means of rubber bushes on the axle 9, or alternatively the latter may be resiliently connected to the beams 5. According to the Provisional Specification, the vehicle wheels may be mounted directly by means of stub shafts on the respective beams 5, the through axial 9 being dispensed with.

Title: Hydroformylation catalyst recovery
IPC: C07C29/16
Filed: 1966-05-16
Abstract: A primary alcohol is produced by reacting an olefin with carbon monoxide and hydrogen in the presence of a soluble catalyst complex containing cobalt, carbon monoxide and a tertiary phosphine in a process wherein at least part of the catalyst is removed from the reaction zone and recycled and a purge stream containing dissolved catalyst and impurities is withdrawn from the recycle stream, at least part of the catalyst complex being recovered from the purge stream by conversion into a less soluble complex, isolation of the less-soluble complex and reconversion into the initial complex. Examples relate to conversion of propylene to n-butanol and 2-ethylhexanol, using a catalyst complex which is largely dicobalt hexacarbonyl-bis (tributylphosphine).ALSO:In a process for the production of a primary alcohol by reacting an olefin with carbon monoxide and hydrogen in the presence of a soluble complex catalyst containing cobalt, carbon monoxide and a tertiary phosphine in which process at least part of the catalyst is removed from the reaction zone and recycled a purge stream containing dissolved catalyst and impurities is withdrawn from the recycle stream, and at least part of the catalyst is recovered from the purge stream by conversion into another, less soluble cobalt carbonyl-tertiary phosphine complex, isolation of the less soluble complex and reconversion into the initial catalyst complex to be re-used in the process.  The initial catalyst complex probably has the formula [Co(CO)3PA]2, where A is alkyl, alkaryl, aryl or aralkyl, and may be recovered by reducing the pH of the purge stream to 3.0 to 8.0, treating with carbon monoxide at a partial pressure of at least 10.2 atmospheres and a temperature of not more than 150 DEG C, optionally with addition of a polar solvent, recovering the less soluble form of the catalyst complex and converting it to the initial form, for example by slurrying in butanol and heating to drive off the carbon monoxide, or by dissolving the complex in a more polar solvent and recycling to the reaction zone for conversion in situ.  In the Examples, the catalyst is largely dicobalt hexacarbonyl-bis (tributylphosphine).

Title: Video display apparatus
IPC: G09G3/28
Filed: 1974-05-16
Abstract: 1466725 Television SONY CORP 16 May 1974 [19 May 1973] 21826/74 Heading H4F In a television receiver employing a flat panel display of the X-Y matrix type (e.g. incorporating gas-discharge, liquid crystal or electro luminescent elements) the video drive pulse signal are modulated in both width and amplitude as functions of the video signal level. The arrangement, which combines the known methods of width modulation or of amplitude modulation used singly avoids the drawbacks of insufficiently uniform characteristics in driving transistors in the case of amplitude modulation and of the slow response of the panel elements in the case of width modulation. As shown in Fig. 5 (in which only a small portion of the panel 1 is depicted) a synch separator 10 supplied with the output of the video detector 8 (of a television receiver) controls a pulse generator 11 which provides vertical and horizontal frequency pulses S V , S H  respectively (see also Fig. 6) as input and as clocking pulses respectively to a shift register 12 which generates drive pulses a 1 , a 2  ... a 5  ... an, to energize, successively via respective transistors the horizontal row lines X1, X2 ... X 5  ... X n . The output of the video detector 8 is also fed via a video amplifier 9 to a level detector 13 which provides sixteen discrete output levels t 0 , t 1  ... t 15  as inputs to a four-bit binary coder 14. The latter produces an output on lines t A , t B , t C , t D  which are respectively connected to multivibrators A 1 , A 2 ...A m ,B 1 , B 2 ...,B m , C 1 , C 2 ...C m  and D 1 , D 2  ... D m . The multivibrator groups A and B comprise monostable circuits producing, respectively pulses P A  and P B  (see Fig. 8) of the same predetermined amplitude and of respective durations “.TH and ¢.TH where TH is horizontal period. Similarly the multivibrator groups C and D which comprise bi-stable circuits produce respective pulses P C , P D , the pulse P C  having the same amplitude as pulses P A  and P B  but of duration TH and the pulse P D  having twice the amplitude of pulses P A  to P C  and a duration TH. The output pulses from each "vertical column" of multivibrators, e.g. A 1 , B 1 , C 1  and D 1  (which are binary weighted 1 2 4 8) are combined and fed to the base electrodes of transistors Q1, Q2 ... Q m  and as the "vertical columns" are successively sampled by gate signals b1, b2 ... b m  (see also Fig. 7), derived from a shift register 16 supplied with the pulse SH and with timing pulses Ss from generator 15, the column lines Y1, Y2 ... Y m  are successively energized to produce, at the intersection with the X row lines, light emission having an intensity determined by the amplitude and width of the combined pulse pattern from each "vertical column" of multivibrators. Fig. 9 shows such pulse pattern for each of the sixteen levels 0 ... 15 the start of light emission being delayed by about ten microseconds as shown by dotted lines.

Electric alarm systems; alarms operated by expansion of solids.-A fire or temperature alarm is arranged to be non-effective in the event of gradual rise in temperature. A composite strip comprising a heat-insulating plate b interposed' between metallic plates a, c having the same coefficient of expansion is mounted over a troughshaped member d of a material which does not conduct heat or electricity. The strip at one end carries a terminal f and at the other end contacts with a screw i in a conducting block g carrying a terminal h.
