Patent GB-928655-A (GB)
Title: A process for the production of desoxy sugars
IPC: C07H3/08
Filed: 1961-11-13
Abstract: 3,6-Didesoxy hexoses are made by treating a 2,5-didesoxy pentose with excess hydrogen cyamide, optionally in anhydrous pyridine solution, and hydrogenating the resulting cyanohydrin in dilute hydrochloric acid with the aid of a palladium catalyst, preferably palladium oxide supported on barium sulphate.  The product which is a mixture of epimers may be used as such or subjected to separation, e.g. by paper chromatography.  Any of the 2,5-didesoxy pentoses or mixtures of epimers may be used as starting materials, however 2,5-didesoxy-D-L-threopentose is stated to be especially useful since it is obtainable by in vitro synthesis as follows.  Commercially available 1-methoxy-but-1-ene-3-yne is treated with sodamine and dimethyl sulphate, yielding 1-methoxypent-1-ene-3-yne; this on treatment with methanol gives pent-3-yne-1-al-dimethylacetal; this is partially hydrogenated (Lindlar palladium catalyst) to pent-3-ene-1-al-dimethyl acetal which on oxidation with either perbenzoic acid or potassium permanganate followed by acid cleavage yields 2,5 didesoxy pentose.  The example relates to the synthesis of 3,6-didesoxy-DL xylo- and lyxo-hexose epimer mixture, separated by paper chromatography starting from the 2,5-didesoxyD.L.-threo-pentose.  The products are stated to be useful for the preparation of artifical antigens.

Title: Improvements in or relating to signalling systems
IPC: H04L1/00
Filed: 1962-10-30
Abstract: 1,078,971. Telegraphy. GENERAL ELECTRIC CO. Ltd., and W. J. BATTELL. Jan. 30, 1964 [Oct. 30, 1962], No. 41099/62. Heading H4P. [Also in Division G4] Single errors in the transmission of 5-bit characters are corrected by generating five check bits for each character before transmission, re-calculating these check bits from the received character, and comparing the received and re-calculated check bits to derive correction signals. If a character is represented by bits V 1 -V 5  then the check bits V 6 -V 10  are calculated from the expressions:- the sum being mod 2 in each case. This is done by use of a trigger which is switched by each binary 1 received to generate #V j , and a mod 2 adder (exclusive OR gate) supplied with signals from the trigger and a circulating register containing V 1-5 . Figure 2 shows the correction arrangement, including a similar trigger 18 counting the received character bits V<SP>1</SP> 1 -V<SP>1</SP> 5  which are fed to circulating register 20. Switch 17 is then changed over and 22, 24 and 25 closed so that V<SP>1</SP> 6  - V<SP>1</SP> 10  are calculated by mod 2 adder 23 and added to the received check bits at 28. Any inequality causes a "1" to be entered into shift register 29 and it is shown that these 1's represent the inverse of the desired corrections for V<SP>1</SP> 1  - V<SP>1</SP> 5  in the correct order, provided that a single transmission error only has occurred. They are thus fed (in inverted form) from the output of 29 to modulo 2 adder 31 provided that the counter 30 has received the number of 1's corresponding to a single error; if more than one error is detected all output is inhibited at 33.

Title: Exposure control device
IPC: G03B7/085
Filed: 1970-08-27
Abstract: 1323565 Photographic camera exposure control EASTMAN KODAK Co 27 Aug 1970 [27 Aug 1969] 41329/70 Heading G2A An exposure control device has an electromagnet which is energized as a function of scene brightness as detected by a photo-cell 51; below a predetermined brightness level an armature 27 is attracted so as to move a signal vane 61 from between a lamp 48 and a light pipe face 55 to cause a warning signal to appear in a camera viewfinder. A diaphragm blade 36 is also moved by armature 27, and a diaphragm blade 37 is moved by a further armature 28. With an increasing current through the electromagnet, armature 28 is moved first to move blade 37 to uncover the lens aperture, and at a higher energization level armature 27 is moved so that blade 36 uncovers the aperture.  Depression of shutter release 15 initially closes switch 45 to energize lamp 48 and to produce  the illumination signal in the viewfinder. Further depression of the release causes attenuation  vane 62 to pivot clockwise to cut off any signal from lamp 48 and to partially cover photo-cell 51. The sensitivity of the cell is thus reduced, e. g. by a half, and the aperture set by the energization level of the electromagnet.

Abstract: 1365114 Change-speed gear FORD MOTOR CO Ltd 6 Sept 1972 [29 Oct 1970] 41365/71 Heading F2D In a torque-converter-driven transmission on a motor-vehicle, providing three reduced ratios, direct-drive and one reverse, by first, second and third planet trains 56, 58, 134, the third train 134 is an intermeshed planet train which receives reverse torque from the two preceding trains 56, 58, and applies it to a final output shaft 82 as a forward torque complementing that delivered directly to output by the said preceding trains 56, 58. Three embodiments, with similar functions, but different train connections, are described. In the first, Fig. 2, the connections are as shown and first ratio, automatic, is obtained by applying a brake 152 to the third ring 138. Input 34 drives the first sun 62 through a one-way clutch 110, which can be bridged for manual low by a rear clutch 102. The compounded first and second trains drive the two rear suns 74, 132 reversely and the output shaft 82 forwardly, the reverse torque on the suns being reversed in the third train and added as a forward torque to output 82. For second ratio, brake 124 is substituted for 152, and the first sun 62 is again driven one or two way, the first and second trains compounding, whilst the third is inactive. For third, the front clutch 86 is engaged, with the brake 124 still applied, and the second train 58 acts alone, whilst for direct-drive fourth, both clutches 86, 102 are engaged. Reverse uses a front brake 96 and rear clutch 102, the first train 56 acting alone. Motors 154, 156, 158, 160, 162, Fig. 4, for engaging respectively brake 96, clutches 86, 102 and brakes 124, 152, are engaged by pressurizing respectively lines 1 .. 6, lines 4 and 5 serving also to release the motors 160, 162 whilst still under brake-apply pressure. For the first four ratios in automatic, pressure is supplied respectively to lines 6; 65, ; 6, 5, 2 and 6, 5, 2, 4; for manual first and second respectively to 6, 3 and 6, 3, 5; and for reverse to 1, 3. Fig. 5, not shown, uses the same three trains as Fig. 2, but the sun of the rear train is now output-mounted, whilst its carrier is secured to the second sun. Ratios and wheel sizes are specified for disembodiment. In Fig. 6, not shown, the planets of the third train are again output-mounted as in Fig. 2, but now the first and second suns are connected together and to the front clurch, whilst the first carrier, second ring and third carrier are all connected to ourput. The gear clutch connects input to the second ring alone, and the one-way clutch is replaced by a one-way brake for the third ring, in parallel with the rear brake, being effective in automatic first only. The third train is mounted in a separate housing, removal of which, with the train, converts the transmission to a three-speed one.

Abstract: 1,160,889. Stamping. AIDA IRON WORKS & CO. Ltd. 23 Sept., 1966, No. 42528/66. Heading B3D. [Also in Division F2] A stamping &c. press comprises a dieholder 6, 7, 8, Fig. 1, means 4 on which the holder is positioned for pressing operations, means 14 to which the holder may be transferred from the pressing station, and means for supplying compressed-air beneath the holder to facilitate its transfer manually. Compressed-air is supplied to circular or rectangular &c. recesses 9, Fig. 2, in the base of the subpress mechanism to raise it for easy transfer to a die change table 14 pivoted to the press. The table may be raised by a handle 14<SP>1</SP> to disengage its stay 15 from a pocket 15<SP>1</SP> and allow the table to be swung down into a pit. A lug on the sub-press mechanism locates it on the bolster 4. In a modification, Fig. 4, compressedair is supplied to three rows of recesses (9), Fig. 5 (not shown), in a platen 17 carrying the sub-press mechanism, 5-7. The recesses are in alignment with three bars 14 of a die-change table supported on pivoted links 18, 19 that may be collapsed by an hydraulic cylinder 26 to lower the bars to floor-level. The bars may be covered by a sheet of metal (32). Instead of supplying compressed-air to separate recesses in the platen or sub-press mechanism, it may be supplied to channels 33, Fig. 8, receiving guide-rails 4a on the bolster 4 and die-change table. Elongated pistons 34 in the channels bear on the rails, and compressed-air supplied behind the pistons raises the platen or sub-press mechanism clear of the bolster 4. Compressedair escapes between the pistons 34 and rails 4a, through holes 37 in the pistons. In a further form, Figs. 10 and 11, the press has a T-shaped bed and a ram co-operating only with the forward limb 102a. Compressed-air is supplied through channels 110a, 110b to holes in the press-bed which are normally closed by ballvalves 139. The valves beneath a platen 104 in the work-position and a further platen 104<SP>1</SP> are opened by the platens so that the platen 104 may be transferred rearwardly and then to the left and the platen 104<SP>1</SP> to the left and forwardly to replace platen 104 beneath the press-ram. The bases of the platens may be flat or recessed 104a. In another form, Fig. 13 (not shown), the ball-valves may be provided in guide rails (140) on the bed and die-change table for engaging recesses in the platen.
