Title: Improvements relating to impulsing relay circuits
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q3/00
Filed: 1957-09-09
Abstract: 832,415. Automatic exchange systems. SIEMENS EDISON SWAN Ltd. Aug. 25, 1958 [Sept. 9, 1957], No. 28381/57. Class 40 (4). An impulsing circuit comprising a relay with a pair of windings, one an impulsing winding and the other an inhibiting winding which is set by a control circuit to either of two conditions, one permitting and the other preventing operation of the relay by impulses applied to the impulsing winding. The invention is applied to a register-sender. The circuit comprises a number of bistable transistor pairs. The circuit is prepared by closure of contacts sc1, sc2 which set inhibition control circuit IC and stop-circuit to normal condition with the left-hand transistors T6, T9 conducting. IC renders T8 conducting so that the inhibit winding Wh of relay P energizes and contact p1 closes the loop. The called number is set up in the digit register in known manner and transmission is initiated by closure of contacts tc1-tc3. tc3 starts up impulse generator IG which causes T1 to supply impulses to winding Wp without effect at this time because the inhibit winding Wh is still energized. IG also supplies impulses at dialling speed over lead L1 to drive counter CC to zero. At this point the last element Z of the counter pulses lead L6 to change over the inhibit control circuit IC so deenergizing winding Wh of relay P. IC also causes the digit register to set up the complement of the first digit in the several stages W-Z of the counter CC. The impulse generator IG continues to drive the counter and impulse winding Wp which is now effective to operate and release relay P, so sending impulses to line. When the counter again reaches zero the inhibit circuit IC is restored to energize Wh and stop transmission. A further counting action, not described, times the interdigital pause after which the next digits is sent. When transmission is complete the digit register marks lead L13 to change over stop circuit ST to re-energize the inhibit winding Wh.

Title: Improvements in or relating to electrical stop motions for knitting machines
IPC: D04B35/14
Filed: 1949-11-08
Abstract: 682,248. Knitting-machines. BROOKS (AUTOS), Ltd., T. J., and HEYNE, W. O. Sept. 13, 1950. [Nov. 8, 1949] No. 28595/49. Class 74 (ii). A stop motion for a knitting-machine comprises a gate and co-operating dropper arm 32 between which the yarn passes, the dropper falling in the event of yarn failure to trip a catch 46 which releases an element 54 to bring one contact 63 of an electrical switch on the element into engagement with co-operating contacts 64 thereby completing a circuit to stop the machine. The catch 46 is so shaped that when tripped an arm 47 of the catch returns the dropper 32 to its initial co-operating position with the gate whereby the yarn can be readily reintroduced between the dropper and gate and the whole mechanism reset. To enable the dropper to trip the catch 46 it is provided at the end of its spindle portion with a turned portion 42 which engages the arm 47 when the dropper falls to rotate the catch about a pivot 45 thereby disengaging the nose 50 of a second arm 48 of the catch from a recess 62 on the arm 53 of the element 54. Release of the element 54 enables it to turn about its pivot 55 under the influence of a spring 59 to bring the electrical contacts into engagement, the catch at the same time being rotated by a spring 51 connected to a third arm 49 so that the arm 47 engages the portion 42 and returns the dropper to its initial operative position. To enable the mechanism to be reset, the pivot 55 extends out of the casing for the mechanism and has a pinned sleeve secured to it which can be turned thereby turning the element 54 until the arm 53 interengages with the arm 48. A number of stop motion devices may be mounted in a single casing and may have all of their electrical contacts 64 connected to a common source. In addition a single operating mechanism for returning any or all of the devices which have been tripped due to yarn failure may be provided and comprises a hand operated sliding bar 75 provided with projections 82 which interengage studs 83 on the elements 54 so as to rotate the elements into engagement with the catch members 46 when the bar is moved in its operative direction. The bar is returned by a spring. Specification 682,245 is referred to.

Abstract: 761,774. Washing teat cups. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 11, 1954 [Oct. 19, 1953], No. 28780/53. Class 138(1). [Also in Group XXVIII] In a method of cleaning a milking cluster and its associated tubes, the cluster and tubes are placed in a container in such a manner that when the container is immersed in a cleaning or sterilizing liquid bath, the liquid fills the tubes and the cluster, without air pockets being formed therein. The parts of the milking apparatus to be cleaned are shown in their normal operative positions in Fig. 1, and comprise teat cups 10, 11 connected by tubes 13, 14 to a collector head 12, a tube 16 connecting the head 12 to the lid 18 of a milk receiving can and a tube 21 connecting the lid 18 with a source of vacuum. The tubes 16, 21 connect with the lid through an oblique pipe 17 and vertical pipe 20 respectively, the pipe 17 ensuring that milk will be delivered on to the can wall. In order that the lid shall make an air-tight connection with the can (not shown), it is provided with a rubber gasket ring 31 mounted on headed pins whose lengths are slightly greater than the thickness of the gasket, whereby the gasket can move away from the lid during cleaning. In order to clean the parts the tubes 16, 21 are disconnected and the milk cluster 10, 11, 12, 13, 14 is mounted in inverted position on a cross-bar 25, Fig. 2, in a cylindrical container 23 having an imperforate side wall, foraminous bottom 24 and' lifting handles 28, 29. The tubes 16, 21 are then positioned in helical formation on a wire helix 27 mounted in a space between the cylinder wall and upstanding pins 26 secured to the wall. The lids and their gaskets are then placed edgeways in the container between the cluster and the helix. On immersing the container in a tank of cleaning liquid the liquid rises through the bottom 24 and ascends up the tubes 16, 21 and teat cups, associated pipes 13, 14 and head 12 without the formation of air locks. The tank may contain a solution of caustic soda or potash with calcium sequestering agents or other additives. The teat cup includes a rubber liner and outer metal shell which latter may be slid axially along the associated tube 13 and retained in position by integral diametrically opposed projections formed on the tube, as described with reference to Figs. 3 and 4 (not shown). This axial movement is effected before cleaning in order to ensure than cleaning liquid will be able to reach the space between the liner and shell.

Title: A method of and apparatus for testing the accuracy of helical springs
Inventor: TERRY NORMAN VICTOR
IPC: G01N3/32
Filed: 1952-11-15
Abstract: 729,582. Gauging departure from standard form. TERRY & SONS, Ltd., H. Nov. 16, 1953 [Nov. 15, 1952], No. 28850/52. Class 106 (2). In a device for indicating when the end faces of a circular helical metal spring are not normal to the axis of the helix, a runway, with a metal base a and insulated side b topped with a metal strip bl, is tilted so that a spring will roll down it in contact with the side and is arranged so that the base and side make an angle with each other which is just obtuse. When a good spring rolls down the runway it will not therefore make contact with the metal strip b<1> on top of the side b whereas one whose end is not square will. The contact of the faulty spring and the metal strip is used as a switch in an indicating circuit or in a circuit for controlling a sorting gate. A second runway linked to the first is arranged with a complementary tilt to test the other face of the spring. Non-return doors k, j check the velocity of the spring in the second runway.
