Title: Coating metal objects with metals by dipping
IPC: C23C2/30
Filed: 1956-04-03
Abstract: Ti, Zr, Hf, Th, V, Nb, Ta or alloys rich in one or more of these metals and having an oxide coating largely of one of these metals, are coated by dipping in and through a layer of molten flux floating on a coating bath of a molten metal.  The coating metal may be one or more of Sn, Cd, In, Pb, Zn or an alloy of one or more of these metals.  The flux comprises aluminium chloride, at least one of lithium, sodium or potassium chlorides, and optionally one or more of the group zinc chloride, stannous chloride and chlorides of the coating metal or metals.  Preferably the aluminium chloride should comprise between 50 and 80 mol per cent of the aluminium chloride/alkali metal chloride portion of the flux and the amount of any of the additional metal chlorides is preferably 1 to 25 per cent by weight of the total flux, but not greater than 50 per cent by weight.  Reference has been directed by the Comptroller to Specifications 780,122, 781,123 and 784,802.

Abstract: 1,212,648. Strapping tool. STANLEY WORKS. 26 Feb., 1969 [8 April, 1968], No. 10356/69. Heading F2G. A strapping tool 50 comprises a strap tensioning unit 54, a strap sealing mechanism 56 movable between inoperative and sealing positions by a tool control mechanism 40 including a single control actuator, e.g. a lever 1, movable between inoperative and operative positions for driving the sealing mechanism between its retracted and sealing positions. The control mechanism 40 also includes a tensioning unit control means which on movement of the actuator into its operative position activates the tensioning unit 54 simultaneously with the movement of the sealing mechanism into its sealing position. In the construction shown, the unit 54, and mechanisms 56, 40 are mounted slidably about an upstanding duckbill 36 of the tool. For effecting the movement of the unit and mechanisms about the duckbill 36, the lever 1 is mounted on a spindle 9 which is provided with a cam 14 from which projects an eccentric pin 15. The pin moves in a slot in the duckbill on actuation of the lever 1. The spindle 9 is provided with a seccnd cam 19 which co-operates with a valve rod of the tensioning unit control means (Figs. 2 and 3, not shown) to allow actuating air to flow to the tensioning unit 54 only on movement of the lever 1 into its operative position. In a modification (Figs. 4 and 5, not shown) the duckbill 36 is provided with a transversely extending pin which is connected to a valve rod of the tensioning unit control means.

Title: Improvements in or relating to starting handles for motor cars, automobiles, and other like purposes
IPC: F02N1/02
Filed: 1923-04-21
Abstract: 218,417. Brace, L. April 21, 1923. Turning - gear. - In order to release a starting- handle in case the engine turns backwards, the handle 3 carries loosely a clutch member 7 and a ratchet wheel 22 engaged by a stationary pawl. A key 14 pivoted in a slot 6 in the handle is normally held by a spring 26 in engagement with keyways 17, 28 in the member 7 and wheel 22. The keyway 28 has a curved face, as shown in Fig. 2, so that if the engine turns backwards the key 14 is forced out of engagement with the keyway 17 and the clutch member 7 is thus disconnected from the handle 3. A spring ring 20 retains the member 7 on the handle.

Title: Improvements in or relating to apparatus for joining the ends of thread, yarn and the like
IPC: B65H69/06
Filed: 1931-04-15
Abstract: 374,572. Splicing yarns. COOK & CO., MANCHESTER, Ltd. and TOWLSON, H. J., 18, Exchange Street, Manchester. April 15, 1931, No. 11114. [Class 120 (iii).] In apparatus for joining the ends of threads of the type in which each of the two thread ends to be joined is held between a clip member and one of two parallel rotatable spindles, one of the spindles carries a bobbin which rotates therewith, and both spindles are connected to a visible indicator which shows the number of turns imparted to the thread ends in order to untwist them, and so enables the same twist to be put back after splicing. The spindles may be provided with clutches, whereby either can be declutched from the driving mechanism. The fixed spindle 5 receives a bobbin carrying the thread to be joined, which is passed to a clip 9 and clip 13 on the spindle 11. The second bobbin is placed on the spindle 12, its thread end passing through clip 14 to clip 10. The pillar 8 carrying clips 9, 10 is adjustably mounted in a slot 7. The handle 22 is turned, and by bevel gears 20, 19 and gears 17, 16, 15 the two spindles are rotated, the amount of rotation being indicated on the dial 26 by a pointer 25 driven by worm and worm wheel 23, 24 from the handle shaft 21. The lengths of thread between clips 9, 10, and clips 13, 14 are then untwisted, each strand is twisted by hand with a strand of the other thread, so that the spliced thread passes directly from clip 9 to clip 14. The handle 22 is turned in the opposite direction until the pointer 25 returns to zero, whereby the correct amount of twist is restored to the spliced thread. Either spindle may be declutched and turned by hand in order to fully untwist both threads should they be twisted to different degrees, by sliding the spindle axially against the pressure of the springs 30 or 31 until the driving pin 29 is disengaged from the castellated driving members 27 or 28. The length of yarn held between the clips should be known, and is preferably 10 inches, whereby for a known twist, the number of revolutions of the spindles necessary to untwist the threads, as indicated by pointer 25, can be easily calculated.

Title: Data storage apparatus

Filed: 1970-03-11
Abstract: 1,240,434. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 11 March, 1970, No. 11548/70. Heading G4C. Data storage apparatus includes a storage unit having a plurality of replaceable storage modules, each stored word having bits stored in different modules, the apparatus being adapted so that at least some of the modules can be replaced by modules of a different bit storage capacity whereby an increment of storage can be added to or subtracted from the storage unit, error correcting means being provided requiring no changes consequential to any resulting change in word length. In a first embodiment, the modules are integrated circuit cards. The minimum capacity is formed by 32 cards each holding 2 data bits of each of 4K words, and 4 cards each holding 2 error-correction bits for each of the 4K words, but 8, 16, 24 or 32 of the data cards may be replaced by cards each holding 2 data bigs of each of 6K words in which case the 4 error-correction cards are also replaced by " 6K " cards. Then there will be 4K words of 64+8 bits as before but also 2K words of (8 or 16 or 24 or 32) + 8 bits as well. On read out, the selected word is placed in a register, two 8-bit data bytes of it being gated, with correction by bit inversion of a single error (if present) under control of the errorcorrection bits, to an output bus, the bytes being selected by the store address register. Gating to the bus may precede completion of the error checking in which case the uncorrected data sent is ignored if correction is necessary, the corrected data being sent after a delay. Double errors are merely detected and cause re-access. Parity bits are generated to accompany the bytes on the bus. The storage unit may be used for microprogramme storage in a computer. A second embodiment also provides second, third and fourth further storage units for main storage (using the previous address register and correction arrangements &c., in common), the second and third each having capacity equal to the maximum capacity of the first unit, and the fourth having a variable number of blocks of 8 " 4K " cards for data, and 4 " 4K " cards for error-correction bits (or the fourth unit may be variable in the same way as the first). Alternatively, double-error correction may be provided. Each cord could store 1 or more than 2 bits of each word. Cards of three or more different capacities could be used.
