Title: Improvements in or relating to bags
Inventor: LOMAS ERIC
IPC: B65D33/28
Filed: 1962-06-15
Abstract: 978,617. Making double-walled bags. LAMSON PARAGON Ltd. June 14, 1963 [June 15, 1962], No. 23163/62. Heading B5D. [Also in Division B8] Holes 5, Fig. 1, e.g. for draw-strings, are made in a folded and transversely sealed flattened tube before it is cut along the transverse seals into bags 4. As shown, the holes 5 are made by punches 6 depressed simultaneously with a heated blade 3 which forms the transverse seals and severs individual bags. Needles 7, Fig. 3, carrying a draw-string 9 are inserted in the holes 10 in the outer wall of the bag at one edge thereof, and are threaded between the walls of the bag and out through  corresponding holes 10 at the other edge until the draw-string is free of the needles. A second draw-string is then threaded through the needles which are withdrawn to insert the second draw-string. The free ends of the draw-strings 9 and 12 are tied to produce the bag of Fig. 6. When the bag is of paper the tube is sealed transversely by adhesive and severed by a guillotine. The longitudinal folding of the tube may be nearer one of its edges to produce an extended flap on one side of the bag mouth which facilitates insertion of the contents.

IPC: G06K15/06
Filed: 1958-09-04
Abstract: 929,299. Electric selective signalling systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 28, 1959 [Sept. 4, 1958], No. 28375/58. Class 40 (1). [Also in Group XIX] Data for printing received from a computor on lines 1 in serial-parallel form is entered into a matrix 4 of magnetic cores forming a buffer store for one line of print, by a decoder 2 which produces for each data character a half-write signal on an appropriate row line 3, and a layout selector 5 which energizes " print position " lines 6 with halfwrite pulses in sequence. The sequence produced by unit 5 may be a single left-to-right sequence if the data is to be printed in the order it is received from the computor, or a desired sequence may be preset by choice of a plug-in unit which provides an appropriate set of interconnections between magnetic cores forming a shift register. When a line of print has been written into the matrix, a shift register 7 reads out the rows in turn in synchronism with the rotation of a type-wheel printer (i.e. a cylinder having like characters on each of a number of generators) so that (for example) all " a "s are printed by signals on line 9 operating print hammer amplifiers 10 as the top row is read out, then all " b "s as the second row is read out, and so on.

Title: Improvements in or relating to rotary valve internal combustion engines
IPC: F01L7/02
Filed: 1944-11-24
Abstract: 575,310. Valves. HAY, W. G. Nov. 24, 1944, No. 23399. [Class 7 (vi)] [Also in Group XXIX] A spring-loaded sealing member 11, interposed between a rotary valve 2 and the cylinder or cylinder head 5, is sealed by split packing rings 13 which engage registering slots in the member 11 and the head 5. The packing rings 13 comprise a pair of rings, one inside the other, with the splits displaced. A wave-spring 15, located in one of the slots or in a separate slot, which may also hold a second pair of split rings, presses the member 11 against the valve 2. The 'member 11 may have a cooling-liquid chamber connected by fluid-tight extensible members with the cooling jacket 6 of the head 5. A pad 31, which may extend along the valve, is spring-loaded along its length by adjustable springs, stops being provided to limit its movement as wear occurs. Alternatively, small individual pads may be distributed along the valve. The valve may be mounted in bearings which move laterally and are spring- mounted. Each bearing may be carried by a ring 46 having, at one side, a pivot 49 pressed against the casing by an adjustable spring 50, and, at the other side, a pivotal connection with a pin 52 adjustably suspended from a self-aligning nut 56, a spring 54 being interposed.

Patent GB-829989-A (GB)
Title: Tape advancer for automatic telephone dialer
IPC: H04M1/274
Filed: 1958-07-22
Abstract: 829,989. Impulse transmitters. KILBURG CORPORATION, J. July 22, 1958 [Aug. 16, 1957], No. 23483/58. Class 40 (4). A telephone dialling machine includes a tape with telephone numbers represented thereon in codes, means for initiating a decoding cycle, means for adjusting the tape from one code position to another, and apparatus operable in response to a separate code symbol on the tape to advance the tape to a second code position after a first code has been dialled. As shown, the machine uses a perforated tape 10, as described in Specification 736,135. At the end of each dialling operation, a gear-wheel 16 is caused to make one complete anti-clockwise revolution. A pin 24 thereon leaves a cam surface 20 and allows a lever 18 to swing clockwise about a pivot 19, applying a sensing finger 22 to the tape 10. If there is a perforation at this point of the tape, the finger 22 passes through and allows the lever 18 to swing further so that a pin 26 thereon enters a notch 27 in an arm 28. When the pin 24 re-engages the cam surface 20 and swings the lever 18 anticlockwise, the tape 10 is advanced by means of arm 28, lever 30, pawl 33, and ratchet 35. The finger 22 is of stepped section and if the perforation in the tape 10 is wide enough to admit the thicker part of the finger this allows the lever 18 to swing far enough in its clockwise movement for a pin 44 to engage a shoulder 45 on an arm 46. The return movement of lever 18 then actuates levers 48 and 55 to close a circuit for the motor of the dialling machine and also rotates a shaft 61 to engage the clutch of the machine. Thus the next number coded on the tape 10 is dialled automatically. This facilitates the initiation of a long-distance call requiring the transmission of more digits than a normal local call.

In a magnetic amplifier, A.C. windings 7, 8, a tapped output impedance 3 and a choke 4 are connected to form a Wheatstone bridge which is balanced when the current in the D.C. control windings 9, 10 is zero. Since the A.C. terminals 1 are connected across one diagonal and the output is taken from the other, i.e. across choke 3, no current flows in the load 6 when the control current is zero. When supplying a load current, the choke 3 acts as an auto-transformer and the effect of the connection of choke 4 is negligible.
