Title: Method for the preparation of diols
IPC: C07B61/00
Filed: 1970-11-25
Abstract: 1321317 Vic-diols from olefins and hydroperoxides COMPAGNIE FRANCAISE DE RAFFINAGE 25 Nov 1970 [26 Nov 1969] 56155/70 Heading C2C Vic-diols are made by reacting an olefin with a hydroperoxide, in an aqueous medium, in contact with a catalyst made by reacting a molybdenum compound with a polyalcohol, separating the reaction products and optionally recycling the catalyst and the olefin, and optionally dehydrating the alcohol resulting from reduction of the hydroperoxide to the olefin and recycling the latter, where it is identical with the olefin used in the reaction. The catalyst may be made by reacting molybdic acid or a molybdate e.g. ammonium molybdate with the required polyalcohol, preferably the diol being prepared according to the invention.
Patent GB-1461084-A (GB)
Title: Detection of the intensity of light
IPC: G03B7/099
Filed: 1973-12-11
Abstract: 1461084 Measuring light intensity CANON KK 11 Dec 1973 [11 Dec 1972 29 Nov 1973] 57252/73 Heading G1A [Also in Division G2] The intensity of an image-forming light beam is determined by impinging the beam on a directionselective diffraction element, the zero order beam proceeding to form an image, and a diffracted beam being directed to a photo-sensitive means for measuring the intensity. In Fig. 2, the diffraction element 14 can be a hologram or a diffraction grating. Light from an object 10 falling on element 14 produces reflected diffracted beams 15 and 16, transmitted diffracted beams 17, 18 and a transmitted non-diffracted beam 20 (i.e. a zero order diffracted beam) which forms an image 13. One or more of the diffracted beams may be directed to a photo-sensitive device for measuring the intensity thereof. Fig. 8, shows a hologram having three separate portions 43, 44, 45 in which the diffraction elements are at different inclinations to each other. The diffracted beams are condensed at different spatial positions, and thus by disposing photocells at three different positions 48, 49, 50 the intensities of the three diffracted beams can be measured independently. Fig. 10 (not shown), is an arrangement for measuring the intensity at the centre of the beam only. In Fig. 28 the diffraction element is divided into two separate areas, a central domain 236 and a circumferential domain 237. The diffracted beams from domain 237 are conveyed by light fibres 240 or 240' to photo-cell 242, and the diffracted beams from domain 236 by fibres 238 to photo-cell 239. Shutters 241, 241' may be provided in this arrangement. Fig. 25 (not shown) represents the arrangement as applied to a rangefinder.

Abstract: 1390682 Moving belt press filter NORITAKE TEKKOSHO KK 14 Dec 1972 [10 May 1972] 57822/72 Heading B1D A travelling band press filter apparatus comprises a lower inclined pervious filter band 1 and an upper inclined pressing band 2. The lower band 1 is entrained around rollers 16, 17 and during part of its travel is carried on a support band 4 running on rollers 23, 25, 29. The upper pressing band comprises a pervious filter screen mounted on an impervious carrier band. The two bands approach each other in the direction of movement to squeeze the material 10 being filtered. The slurry to be filtered is added to the band just before it enters the pressing zone and liquid filters by gravity through the band and filtrate is collected in tank 19. The cake is then pressed, filtrate passing upwardly and downwardly through the filter screens into channels between the screens and the impervious carrier bands and defined by upstanding projections on the carrier bands and then flowing into tank 19. The lower filter band has upstanding edge strips to prevent escape of pressed cake sideways. Protrusions 15 on the upper band prevent escape of pressed cake backwards. Cake is removed from band 1 by scraper 37 and the band is washed by a stream of liquid from nozzle 38. The filter band 1 is formed of a plastics woven fabric or fine metal mesh which may be backed by a coarser metal mesh.

Patent GB-776270-A (GB)
Abstract: 776,270. Calculating - apparatus. OLYMPIAWERKE AKT.-GES., [formerly OLYMPIA WERKE WEST GES.]. Nov. 19, 1953, No. 32068/53. Class 106 (1). In a ten-key machine having differential actuating mechanism for an accumulator settable under control of a set-pin carriage, a further differential mechanism is adjusted by the first during setting, and is then operable to impart repeat actuations to the first. Differential racks 10 are adjusted to the setting of a pin carriage 14 through the intermediary of bell-cranks 11 upon clockwise movement of a bail 12 normally retaining the bellcranks. A repeat actuating mechanism for the racks comprises a shaft 2 mounted between arms 1 rockable about fixed pivots Ds, and on the shaft adjustable actuating segments 3 each with a stud 8 engaged in a slot 9 formed in a downward extension of the corresponding rack 10. Normally (Fig. 3) the studs 8 overlie the pivots Ds and this position persists as regards those racks 10 which remain at zero during setting. Other studs 8 are displaced (Fig. 5) differentially from the pivots Ds, the segments 3 rocking about the shaft 2. A bar 4 then engages toothed peripheries of the segments to lock, them in adjusted position, being brought into engagement through a push-rod 103 from a lever 102 rocked by the bail 12 at the conclusion of its clockwise movement. With the segments 3 thus adjusted to the settings of the racks 10, repeated entries of the set amount can be made by rocking the assembly of segments 3 on their shaft 2 about the pivots Ds. This is effected by rotation of a crank-shaft 6 which also carries a cam for engaging the accumulator 16 at the appropriate part of the stroke of the racks 10. The settings of the racks 10 are transmitted to type-bars 20 through pinions 117 which can be moved clear of the racks, when prints are not required, by operating a finger lever 113.

Title: IC engine induction system
IPC: F02B31/08
Filed: 1978-06-14
Abstract: The sub-intake passage 35 has a substantially smaller cross-sectional area than the main intake passage 17 so that a given mass flow through this passage will enter the combustion chamber at a higher velocity than that flowing through the main intake passage. Throttle valve means 28, 42 are provided for sequentially controlling the flow into the combustion chamber through the main and sub-intake passages to cause substantially all of the intake air flow at idle to pass through the sub-intake passage to promote high velocity induction and, at least in some embodiments, controlled swirl to the intake gases. This swirl may be obtained by directing the sub-intake passage port at the intake valve 36 in such a way that the intake valve deflects the flow of the intake gases in a swirling motion. <IMAGE>

Title: Radar apparatus
IPC: G01S13/04
Filed: 1980-07-29
Abstract: A microwave proximity detector system has a microwave noise source 2 that supplies signals to a transmitting aerial 3 and to a delay unit 5. Microwave energy reflected off external objects 7 is received by a second aerial 6 which supplies signals directly to a correlator 4. The correlator 4 also receives signals from the delay unit 5 and produces output signals that are dependent on the degree of correlation between the two input signals and the amplitude of the received energy. This gives a response that decreases sharply beyond a predetermined distance, dependent on the delay introduced by the unit 5. The microwave signals may be converted to a lower intermediate frequency prior to correlation, (Fig. 5). <IMAGE>
