Patent NL-7008314-A (NL)
IPC: F16L37/23
Filed: 1970-06-08
Abstract: 1,257,893. Pipe joints. JOHNSON CORP. 6 May, 1970 [12 June, 1969], No. 21867/70. Headings F2C, F2G and F2U. In a connection wherein a rotatable conduit member, e.g. drying drum 10, Fig. 1, is fluidtightly connected to and drives a nipple 35 rotatably mounted in a stationary conduit part, a combined pipe joint and detent clutch is provided between the nipple 35 and the rotatable member so that the two may be joined or separated while the member continues to rotate, the clutch mechanism being operated by a manually-operated means 46 which is movable axially with respect to the joint. In the embodiment shown, Fig. 2, an extension 34 of the nipple 35 has an enlarged end 42 counterbored at 44 to accept an extension 36 of the journal flange 20 of the drying drum 10. Fluid sealing is achieved by O-ring 64, and the overlapping of ring 68 prevents turbulence. Mechanical coupling is via balls 54 in radial bores 56 engaging in depressions 58 circumferentially spaced round extension 36. The depressions 58 are circumferentially elongated (Fig. 3, not shown) to assist location of the balls when the clutch is engaged by sliding the spring-pressed collar 46 into the position shown. To disengage the nipple 35 from the drum 10 the collar 46 is manually slid leftwards and the balls are cammed, by continued rotation of the drum, into groove 60. The arrangement is particularly suited to the drying rollers of paper-making machines so that the machine need not be stopped for repairs to rotary seal 28.

Title: Drive for open end spinning machines
IPC: D01H4/12
Filed: 1974-09-26
Abstract: Rotor can rotate freely on the end of an arm, whose other end pivots on a rod orthogonal to the axis of the machine's stator, to occupy selectively a working position, in which it is releasably locked and in which the rotor and stator cooperate, or an inspection position in which they are disengaged. The rotor is driven by a multiplying belt drive via a small pulley integral with the rotor and a large loose pulley on a shaft carried on the arm near the rod. The large pulley is integral with a 3rd, pref. smaller pulley which contacts a drive belt parallel to the rod when the arm is in working position. When the arm is in inspection position, the 3rd pulley is remote from the belt.
Patent NL-7416344-A (NL)
IPC: A44B19/30
Filed: 1974-12-16
Abstract: In a slider having a body with an island or separator formed centrally at its flared front end, a locking pawl is arranged between a pair of ears projecting upwardly from the separator in spaced parallelism. A retainer pin extends between the separator ears over the locking pawl in registered relationship to an upwardly opening recess formed adjacent the front end of the latter. Normally, the locking pawl is yieldably urged, as by a leaf spring mounted thereunder to releasably engage the retainer pin in its recess and to have its tapered or pointed rear end held in interference contact with the rows of interfitting fastener elements passing through the slider body. Upon exertion of a pull on a pull tab connected to the locking pawl, the latter will pivot about the retainer pin to permit the free movement of the slider along the fastener elements.

Title: Lockable mole-trap construction - has two pairs of pivoting scissor clamps between which soil dug by mole passes to activate trap
IPC: A01M23/26
Filed: 1982-02-23
Abstract: The trap construction consists of two scissor type blades (2) which are fixed to wire type tension arms (1,3). Both arms turn around a common hinge pin (5) around which a cylindrical helical spring is fitted under tension to bring. the blades together. The teeth final position depends on the centre distance (7) of the hinge pin (5) and tension arms. The teeth pair configuration is such that in the set position they nestle in the mole hole side wall. The blade inside space is concentric w.r.t. the mole hole circumference, and leaves this space free. When the trap is activated the mole is caught in the space between the pair of blades thus not damaging the moles skin.

Title: Combined accelerator and brake pedal for motor vehicle - pivots for throttle operation and moves directly downwards for braking
IPC: G05G9/00
Filed: 1988-05-24
Abstract: The driver of the vehicle places the sole of his foot onto the upper surface of the pedal (1) so that his heel rests in the raised rim at its lower edge. A bracket on the rear of the pedal allows the pedal to pivot on a horizontal shaft. The 'eye' on the end of the inner core (16) of the accelerator cable is fastened to a pin (14) on the side of the panel. The throttle is operated by tilting the pedal backwards or forwards. One end of the pivot shaft is mounted in a swinging plate (6), while the other end is linked, via a crank assembly to a conventional brake pedal and pivot arm (13). When the driver wishes to brake, he pushes against the main pedal. This operation releases any tension on the throttle cable inner (16) and operates the brake via the brake pedal.
