Title: Improvements in chucks
IPC: B23B31/175
Filed: 1945-08-13
Abstract: 600,038. Chucks. ATELIERS DE CONSTRUCTIONS DE LA SEINE, and HUBERT, E. J. M. Aug. 13, 1945, No. 20814. Convention date, Jan. 2. [Class 83 (iii)]  In a chuck in which the jaws open and close without axially displacing the work and are operated by a screw and nut, a stationary screw-threaded member acts through a ballbearing on a flange on the revolving spindle. A hollow spindle 1 and a rod 3 within it rotate together and a screw-nut combination 6, 7 is journalled on the'spindle. The member 6 is secured to the machine frame by a pin 5 and bears against a flange 2 on the spindle through a ball-bearing 11. The axial movement of the member 7 when rotated by a handle 10 is imparted through a ball-bearing 12 to a flange 4 on the rod 3 and, through a ring 19 engaging levers 17, operates axially-sliding jaws 16.  The Specification as open to inspection under Sect. 91 comprises also a chuck as shown in Fig. 2 (Cancelled) in which the member 16, through a ball-bearing 28, moves a sleeve 24 operating a coned split collet 21. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1371613 Bottle inspection FORDS (FINSBURY) Ltd 16 Sept 1971 [16 June 1970] 20886/74 Divided out of 1371611 Heading G1A The Specification relates to the mechanical aspects of the bottle inspection device of the parent Specification 1371611/70. Bottles 1 are guided along a conveyor belt 2 so as to pass on to a rotating glass disc 4 beneath which is a light source and above which is a photo-cell device (a storage mode detector array, disclosed in the parent) to enable inspection of the bottles base. The glass plate 4 is cleaned continuously by a rotating brush 6, drip fed with detergent and by two squeegee blades 7 and 8 which have rinsing water applied between them. If a reject signal is produced by the photo-cell device, an electric or pneumatic actuator 10 will push a lever 11 into the bottles path, halting the flow of bottles temporarily while an ejector device 13 is activated to push the bottle through an opening in an adjacent guide wall 3. Apparatus incorporating the mechanical reject mechanism forms the subject of Specification 1371612. Divided out of the parent Specification 1371611.

Patent GB-708173-A (GB)
Title: Process and apparatus for melt spinning
IPC: D01D1/06
Filed: 1950-08-24
Abstract: Poly-e -caprolactam is melt-spun by feeding it in solid form to an initial heating device and delivering it therefrom in molten form to a sump or reservoir and thence to the spinning pump, the initial heating device and the sump being kept at a temperature not more than 15 DEG C. above the melting point of the polymer and p  below the spinning temperature, and the source of heat for the spinning pump and spinneret being separate from the source of heat for the initial heating device and for the sump respectively, whereby the melt is heated to the spinning temperature immediately before the spinning. The capacity of the sump is sufficiently great to allow the heated material completely to melt before reaching the spinning pump.  In the example poly-e - caprolactam having a melting point of 214 DEG C. and containing 1 per cent. of water-soluble monomers is melted in a heating chamber and flows by gravity into a sump of such capacity that the average time required for a particle of the melt to travel from the initial heating chamber to the spinning pump is 90 minutes. The chamber and the sump are surrounded by heating jackets and the temperature of the jackets and of the melt in the sump is 225 DEG C. The melt flows from the sump to a block containing the spinning pump and spinneret and heated by a third jacket so that the spinning temperature is about 254 DEG C.  The content of monomers in the melt reaching the spinneret is 3 per cent. as compared with 5.9 per cent. in the usual melt-spinning process.

Title: Improvements in or relating to test circuits for group selectors in automatic telephone exchanges
Inventor: SLOANE RONALD VICTOR JAMES
IPC: H01H67/00
Filed: 1958-07-01
Abstract: 856,667. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. May 21, 1959 [July 1, 1958], No. 21011/58. Drawings to Specification. Class 40 (4). In an arrangement for detecting disconnected trunk faults (i.e. faults in which the usual battery from the impulsing relay fails to be applied across the speech wires, due, e.g., to a disconnection or to a blown fuse) in group selectors arranged to step on in such circumstances, means is provided for counting the number of loop current interruptions and giving an alarm if the number exceeds one. It is observed that when switch-through occurs from one selector to the next there is a temporary interruption of the loop current. If such a fault occurs two switch-through operations will occur. The invention is incorporated in a routine tester, arrangements being provided to switch a highspeed relay into the loop during the intertrain pause and to count the number of its releases during that pause. If this exceeds one, alarm is given and a holding earth is extended to enable the switch having the faulty outlet to be traced.

Abstract: 650,851. Bowl-type earth scrapers. LE TOURNEAU, Inc., R. G. Aug. 9, 1948, No. 21021. Convention date, Aug. 19, 1947. [Class 68 (i)] In a bowl-type earth scraper the tailgate 10 has at its rear a carriage 12 which is guided along a horizontal beam 13, secured on a rearwardly projecting framework 3 on the bowl 1, this framework carrying the road wheels. Mounted on a cross beam 4 of this framework 3 is a reversible electric motor 14 and an associated cable drum 17 around which is wound a cable 18 so as to provide a pair of opposed runs 19, 20, the run 19 passing over a sheave 21 mounted on the framework 3, back to a sheave 23 on the carriage 12, and over a sheave 24 on the framework to be dead-ended at 25 on the carriage. The other run 20 passes forwards about a sheave 26 on the back of the tailgate, and around a sheave 27 mounted on the framework coaxial with the sheave 24 to be finally dead-ended on the tailgate. Rotation of the drum causes either positive advancement or retraction of the tailgate within the bowl, depending on the direction of rotation.

The wheel axles 32, 33 of each vehicle part may be connected by rods 34, 35 to the other part to allow them to follow the steering action. Alternatively (Fig. 5 not shown) the lever carrying the sensor may, be connected directly to the axles which are moved as indicated above. In another embodiment the vehicle part 1 has a single steerable wheel and the vehicle parts are interconnected by a linkage which causes the part 2 to follow the steering action at the steerable wheel.

Abstract: 866,835. Typewriters &c. HANDLEY, J. June 26, 1959 [July 2, 1958], No. 21140/58. Class 100(4) Letter-spacing arrangements. A shaft 6, e.g. the lead screw which advances a type-head across the platen of a teleprinter, is driven through a friction clutch 5 and controlled by a ratchet 1 and a pawl 9, the latter being advanced by spring means 11 to meet a succeeding tooth, and friction means being provided to decelerate the ratchet after its re-engagement with the pawl. The pawl 9 is actuated by a finger 10 and when released from the ratchet wheel 1 a spring 12 moves the pawl assembly upwards until a link 13, on which the pawl assembly is mounted, engages an adjustable stop 14. As the pawl assembly moves upward the second pawl 15 on the assembly engages a succeeding tooth on a second ratchet wheel 16. Upon the return of finger 10, spring 11 causes pawl 9 to re-engage ratchet 1, the initial shock of impact being taken by a spring portion 8 of the pawl 9. Momentum induced in the pawl assembly is resisted by spring 12 and by the pawl 15 driving the ratchet 16 against a second friction clutch 17. To resist the greater impact of a tabulation run a stop 18 for the pawl 15 is mounted on a rocker plate 19 which rests against a compression spring 20. Specification 808,704 is referred to.
