Title: Improvements in or relating to cut-off devices for knitting machines especially circular knitting machines
IPC: D04B35/10
Filed: 1962-07-25
Abstract: 1,001,422. Knitting machines. SDRUZENI PODNIKU TERTILNIHO STROJIRENSTVI. July 25, 1962 [July 29, 1961], No. 28517/62. Heading D1C. A cut-off device for a knitting machine comprises an electro-magnetically actuated catch, a switch operated by an auxiliary relay actuated by devices monitoring, e.g. the needle latches or thread, to control a circuit comprising a D.C. current supply and a condenser connected across the electromagnetic winding of the catch, the catch being operatively connected by a lever 8 with a manually operated cam 4 biased to the "off" position and so shaped that, when turned to the "on" position it engages the lever with the catch and through a further lever 12 engages the main clutch, energisation of the electro magnet releasing the cam and hence disengaging the clutch. As shown, the nose 12 of lever 13 engages the periphery of cam 4. One arm 7 of lever 8 is spring biased against a claw on cam 4, while the other arm 17 of lever 8 has a claw 16 to engage a recess 18 in the spring-biased armature 20 of electro-magnet 25 which is connected in the circuit shown in Fig. 3. When starting, the machine button T is depressed and coil C is energized to switch contacts 27, 29, 30 to positions "b". Closure of contacts 30 energizes coil C1 to close contactor ST and start motor E. Contacts 29 close a holding circuit for coil C. Contacts 27 close a circuit through a capacitor 26 and a rectifier 28 connected to the secondary winding of transformer Tr. The clutch is now engaged by turning handle 3 which is held by lever 8 whose ends engage claws and lever 20. If a defect occurs, the contacts of one of the devices HJ, HP 1  or HP 2  close to short circuit coil C allowing contacts 27, 29 and 30 to return to position "a". Contacts 27 connect capacitor 26 in series with coil 23 which is excited by the discharge of the capacitor to attract armature 20 and release lever 8 and hence disengage the clutch. Failure of the mains current or operation of a button T, has the same effect. To restart the machine, T 2  must be depressed and the clutch re-engaged.

Title: Improvements in or relating to printing mechanism applicable to statistical, calculating and like machines
Filed: 1934-10-05
Abstract: 445,296. Typewriters &c. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Oct. 5, 1934, No. 28570. Convention date, Oct. 7, 1933. [Class 100 (iv)] Relay actions; type-wheel actions.-In printing-mechanism for statistical and like machines, a reciprocating type-carrier is associated with two positioning-members which are advanced and restored during alternate cycles, one member being advanced while the other is restored, and means is operated during each cycle for differentially arresting the advancing member to determine the position of the type - carrier. The mechanism enables the machine to operate at a high speed, since the type-carrier moves from one position to another without being restored to a normal position, and the restoring part of a cycle can therefore be omitted. In the mechanism shown in the Figure, a type-carrier 20 is formed with a block 23 for co-operation with positioning-fingers 24, 25 and restoring-fingers 26, 27, the fingers and type-carrier being revoluble on a shaft 21, and the fingers 24, 26 and 25, 27 being connected by springs 28, 29 respectively. The fingers 24, 25 have extensions 30, 33 connected by springs 31, 34 to bails 32, 35 revoluble on the shaft 21. The bails are oscillated by means of cams on a shaft which makes one revolution during two card-cycles, the cams being so arranged that the bails move towards and away from each other during alternate cycles. The fingers 24, 25 are formed with racks 41, 43 co-operating with stop-pawls 44, 45 which are normally latched by the armature 48 of a cardcontrolled magnet 12. During one cycle, the bails move away from each other, and the positioning-fingers 24, 25 are advanced and restored respectively, the final position of the finger 24 being determined by the stop-pawl 44. The type-carrier is moved by means of the finger 27 and is arrested in the required position by the finger 24, or is returned thereby to that position. During the next cycle, the bails move towards each other, and the finger 25, when arrested by the stop-pawl 45, determines the position of the type-carrier.

Title: Method for coating graphite with niobium carbide
IPC: C04B41/87
Filed: 1959-08-25
Abstract: The graphite moderator structure of a nuclear reactor is coated with niobium carbide.  The metal is applied to the surface in a freely divided form.  The graphite and metal are degassed, at a pressure of 10-3 mm. Hg. and 1400 DEG C.  Then the temperature is rapidly raised to 2600 DEG C. when the metal melts, wets and spreads over the graphite.  If the temperature is reduced after wetting, the coating is of metal alone while if the temperature is maintained the metal is converted to the carbide.  The temperature is raised rapidly initially to prevent the formation of the carbide before wetting.

Title: Improvements in or relating to waterproof laminated sheet material and method of making such material
IPC: A47B96/20
Filed: 1952-11-19
Abstract: 730,052. Compound sheet materials. MESSING, B. Nov. 19, 1952, No. 29245/52. Class 140. [Also in Group XI] Two outer flexible layers of self-sustaining moisture-resistant thermoplastic material and an intermediate layer of porous padding are formed into a laminate and the outer layers are fused by heat and pressure through the intermediate layer at selected predetermined points, the padding between the fused points being uncompressed. The thermoplastic material may be a vinyl polymer, polystyrene, polyethylene or cellulose acetate, and the porous padding may be comprised of cotton, shoddy, wool or jute. It is preferred to fuse the outer sheets by subjecting the assembly to a high-frequency electric field. If desired, a plurality of padding layers interposed between successive sheets of thermoplastic material may be employed. As shown, thermoplastic sheets or webs 13, 14 from supply rolls 10, 11 are led together with an intermediate layer 16 of padding from roll 15 between guiding rolls 20, 21 and thence to heating and pressing rolls 22, 23. The pressing rolls 20, 21 may be formed with any desired design made by ribs 30. These ribs extend to the shafts 31, 32 on which the rolls are mounted, and the shafts are connected to a source of high-frequency electric current 33. The current is thus conducted to the material compressed by the ribs 30 and a high-frequency electric field is set up, thus fusing the thermoplastic material through the intermediate layer. The outer edges may also be compressed and fused by ribs 36.
