Title: Improvements in or relating to curing agents for epoxy resins
IPC: C08G59/68
Filed: 1962-07-13
Abstract: A curing agent for epoxy resins having more than one epoxy group per molecule, comprises a major molar proportion of an anhydride of a polycarboxylic acid having two to four carboxylic acid groups, and a minor molar proportion of a mono-salt of an organic amine and a polycarboxylic acid having two to four carboxylic acid groups.  The curing agent may contain from 0.2 to 45 mol. per cent of the amine mono-salt, based on the total amine mono-salt and anhydride.  The curing agents may be prepared by adding appropriate amounts of water and amine to the anhydride. In examples, curing agents are obtained from methyl-5-norbornene -2,3-dicarboxylic anhydride and benzyldimethylamine, and are used to cure a glycidyl polyether of bisphenol A.  Other materials are mentioned.

Title: Improvements in and relating to the reading of the picks from a pattern card in shedding devices for looms
IPC: D03C1/14
Filed: 1949-10-25
Abstract: 671,002. Double-lift dobbies. STAUBLI, R., STAUBLI, O., and STAUBLI, H., (trading as STAUBLI & CO., GEB.). Oct. 25, 1949 [Oct. 28, 1948], No. 27360/49. Class 142(i) A double-lift dobby which can be reversed without disturbing the shedding sequence has a group of reading needles 1 acting through bell cranks 14, push needles 15, a lifting rail 24, and lifting needles 16 to set lower lifting hooks 2; a second group of reading needles 3 acts through parts 18, 19, 23, 20 to set upper lifting hooks (not shown). Whilst the upper lifting knife (not shown) is opening the shed selected by the reading needles 3, and the lower lifting knife 22 is performing its lost motion, a cam 27a rocks a lever 31 carrying a bar 32 to lift all the reading needles cut of the pattern card. A cam 26 then swings a lever 8, thereby moving the needles 1 two pattern rows to the left, so that they drop into the pattern card on the opposite side of the needles 3 to read the next pick. When the lifting knife 22 has opened the shed for this pick, a cam 27b lifts the reading needles out of the pattern and a tooth 28 turns the pattern cylinder 33 on a mount equivalent to two picks; simultaneously, the cam 26 releases the lever 8, allowing the needles 1 to return to the position shown where (since the pattern card has moved the same distance) they drop into the holes from which they were just lifted. When the dobby is reversed, the same sequence occurs in the opposite direction.

July 10, 1963 [July 30, 1962], No. 27412/63. Heading B8B. A mobile tower crane has a tower mast 4 pivotally connected at 5 to a carrying frame 3 and jib 6 pivoted at 7 to the mast. The arrangement is such that in the fully folded condition the centre of gravity of the assembly lies between the pivot 5 and the outer end of the jib so that when retaining means are released the tip of the jib tends, as shown, to engage the ground 2, and the mast 4 tends to move to its erected position. Operation of one of the driving mechanisms such as the lifting blocks 8 then tends to erect the mast 4 fully and then to raise the jib 6 to its horizontal operating position. A modification alters the position of the pivot 5.

Title: Apparatus for instructing aircraft pilots in instrument flying methods
IPC: G09B9/26
Filed: 1937-10-12
Abstract: 498,940. Instructing aviators. LORENZ AKT.-GES., C. Oct. 12, 1937, No. 27705. Convention date, Oct. 15, 1936. [Class 4] Apparatus for demonstrating instrument-flying methods includes a visual representation of a landing ground and an aircraft, the aircraft being movable in all directions, and means for simulating acoustically or optically the signals of a radio beacon according to the position of the aircraft on the landing ground. As shown, the wall 1 of an open box has an aperture 2 covered by a translucent pane bearing a sector 3 and two characteristic signs 5, 4. The representation of the aeroplane is projected on to the pane and the projection apparatus is translatable along a pendulum 6 movable against the action of a spring 9. Rotation of a knob 13 through an endless band translates the image and when the signs 5, 4 are reached a contact arm reaches one of contacts 34 causing the headphones 15 and a loud-speaker 16 to be energized. This corresponds to the usual presignal and main signal heard on an aircraft approaching a landing ground on a radio beam. When the direction of translation of the aeroplane is reversed the image is consequently reversed. When the lever is displaced on movement of a knob 7 due to the action of a contact arm 35 and a known device for generating keying signals the appropriate signal in relation to the radio beam is reproduced in the devices 15, 16. A pointer 17 gives an optical indication corresponding to that given by the usual direction indicator of an aircraft. The Specification as open to inspection under Sect. 91 comprises also means for projecting and changing the orientation of the image. This subject-matter does not appear in the Specification as accepted.

[Classes 132 (ii) and 132 (iii).] Toy apparatus, particularly for use in games is of the kind comprising two devices bearing indications such as numeral discs or numeral disc and pointer and has a friction disc gearing between the two devices. The apparatus shown in Fig. 1 comprises a handle 3 and disc 2 on a shaft 1 gearing by friction disc 4 and roller 5 with the shaft 6 of a pointer 7. A fixed index 11 is provided between the disc 2 and the pointer 7. In another form the shaft 6, Fig. 2, drives by toothed gear 9, 10 the shaft 6a of a disc 8 serving instead of the pointer. In the model aeroplane shown in Fig. 3, the propeller 7 serves as the pointer. The friction disc 4 has secured to the underside thereof a toothed ring 12 engaging with a toothed wheel 15 secured on the shaft 13 to which are fixed the wheels 14. The disc 2 is rotated by turning the handle 3, by means of a cord or by pushing the aeroplane and allowing it to run. A pair of friction discs may be substituted for the toothed gearing 9, 10 of Fig. 2. By providing at least one pair of friction discs slipping may be utilized to adjust the parts of the apparatus with respect to one another. For enabling the toy to be used in the game of " Lotto " &c. both the spinning disc 2 and also the propeller or pointer 7 or the indicator disc 8 are provided with numbered sections. According to the Specification as open to inspection under Sect. 91 (3) (a) a pair of toothed gears may be substituted for the pair of friction discs 4, 5, Figs. 1 and 2.

Filed: 1951-11-27
Abstract: 706,447. Swath-turners. NICHOLSON, A. C. Nov. 27, 1951, No. 27764/51. Class 6 (3) Relates to a lifting and lowering appliance for working parts 36 pivotally mounted on an agricultural machine so as to be movable by the rocking of a lever 2 secured to a shaft 1 rotatably carried by the framework 5 of the machine. According to the invention, the lever 2 has a subsidiary lever 11 pivoted to its upper end and adapted, upon successive pulls on a cable 25, to release latch mechanism 10, 15, 17 locking the tools in their raised or lowered positions and thereafter to permit the tools to fall into ground-engagement or cause them to be raised by a continued pull on the cable. The lever 11 is associated with a fixed member 23 carrying pegs 6, 7, one of which (6) serves as a pivot for a retaining hook 15 which holds the tools raised by engaging a projection 16 on the lever, Fig. 6, and the other peg 7 co-operates with a hook 10 on the lever to hold the tools in their lowered position, Fig. 2. With the system in the position shown in Fig. 2, a pull on the cable 25 first releases the hook 10 and then moves the system to the raised position, Fig. 6, where the hook 15 engages the projection 16. A further pull on the cable causes the end 18 of the hook 10 to strike the end 26 of a detent member pivoted to the hook 15, so that the latter is unlatched to permit the tools to fall. The system is applied to a swath-turner having raking heads 36 pivoted on shafts 34 and linked by adjustable rods 21 to arms 20 on the rock-shaft 1.
