Abstract: 1,250,563. Knitting. WIRKMASCHINBAU KARL-MARX-STADT VEB. 19 Feb., 1969, No. 9012/69. Headings D1C and D1K. A single cylinder circular machine is equipped with a semi-circular welt dial pivotable about a horizontal axis for transferring loops held by welt instruments from one side of the cylinder to the other to close a tube. Each instrument comprises at least two parts, one part having a hook to receive a loop, the other a tongue for transfer. The hook is variously constructed to allow the loop to slip over to the tongue when the dial is pivoted. The hook of the one instrument may be grooved or slotted to receive the tip of the tongue. Alternatively the instrument may comprise two identical hooked parts, or have an additional hook attached to it, between which the tongue engages. In other embodiments co-operating surfaces on the tips of the hook and tongue abut one another when the instrument is closed. In still further embodiments the hook and tongue overlap and are resiliently pressed together. The parts of the instruments may slide in common, or separate grooves.

[Also in Division G1] A loading indicator for a crane 20 comprises a load cell 30 and a function generator 68, including a potentiometer 53 mounted on the boom 22 and having a winding of which the resistance is variable as the cosine of the angle of the boom to the horizontal, the potentiometer wiper contact being attached to a pendulum to cause motion of the contact relative to the boom as the latter is raised, and a further potentiometer 54 having a plurality of top points 60b to 60k, each connected to a separate amplifier 86-94 so that the voltage distribution on the winding of the further potentiometer simulates a desired load vs. boom angle law, Fig. 3 (not shown), an alarm 70 being actuated when the output from the wiper contact of the further potentiometer exceeds a predetermined value. A meter 37 is connected to display either crane load or crane radius and which latter is the horizontal projection of the crane boom length L, i.e. L cos a where α is boom elevation angle. The voltage acting upon the alarm is the product of load and radius and is displayed on a meter 38 calibrated in percentages of crane capacity. The voltages from amplifiers 86-94 are individually adjustable to simulate a required law on potentiometer 54 by switches 75a-75j controlling amplifier input resistances and/or by a switch 74 in the feedback loop of an amplifier 73 supplying the output of the load cell to the amplifiers. Alternatively a programme card interposing preset resistors in the amplifier input circuits may be utilized. The load cell is a differential transformer. Reference has been directed by the Comptroller to Specification 1,219,636.

Abstract: 1,266,161. Locks. GENERAL ALARM CORP. 8 April, 1969 [16 April, 1968], No. 17756/69. Heading E2A. The main bolt 15 of a door lock is held in its retracted position by a blocking pin 60, Fig. 5, lying in a slot 56 in the bolt and held there by a latch-bolt-shaped trigger member 37 which is forced back when the door is closed, Fig. 7, thus allowing the blocking pin to rise into slot 57 to free the main bolt for engagement with striker 14 under the pressure of spring 39. The lock also includes a chainengaging arrangement 16 operated by a knob 22. The springs 39, 44 lie inside their respective bolts 15 and 37, and pin 42 at the head of spring 39 is hardened against sawing. The trigger member 37 has a latch-like ramp 50 slotted at 51 to house a pivoted latch element 54 biased by the spring 44 through a follower 47 to a position at which it fastens at shoulder 54a against the casing to prevent inadvertent pressing in of the trigger bolt 37, but allows inward movement of the trigger when the door is closed against the striker 14. The main bolt 15 is manually retractible by rotation of inner and outer knobs 17 (and 19), Fig. 4, by the intermediary of a lever 61 acting on pin 62 and tilted by means of a cam (69, Fig. 16, not shown) on the spindle of knobs 17 and 19. An inside thumb-turn 20, prevents rotation of the outside knob 19 by means of a lever 71 which inserts a detent 74 into a slot 76 in the cam to prevent its rotation. An eccentric 75 controlled by a cylinder lock (82) or thumb-turn 20, lies between upstanding arms of the lever 71 to pivot it about 72 to operate the detent 74. This eccentric carries an indicator disc (77, Figs. 12 and 16, not shown). The main bolt 15 is dead-locked in the fastening position by a bar 86 loaded by spring 87 being pressed in by the lever 61. A roller 91 engaging slots 89, 90 in the main and dead-locking bolt to hold the bolt in the projecting position when the bar 86 is pressed in as shown in Fig. 7. The main bolt 15 may be bolted from inside by a pin 94 on button 21 engaging a hole 92. A force-attempt alarm comprises a normally open switch 104, and a chain anchor 115 engageable by a chain pick-up rod 106 controlled by laterally movable knob 22, Figs. 1 and 10. The anchor 115 is secured to a chain 119 on a reel 120, so that if the door is forced, the tension of this chain moves the cover 96 of the striker bodily to operate the alarm switch 104. In a modification for glass doors (Figs. 17-22, not shown) the main bolt (130) carries floating block (139) which controls the dead-locking bolt 86 and is moved by the lock (156) or by an internal handle through cams 150, or 150. This arrangement takes the place of lever 71. The lock (156) may lie within the operating handle (157, Figs. 20-22, not shown) which slides axially on the lock body. A lock-bolt (167) holds the handle axially into contact with a detent (170) which prevents it rotating.
