Abstract: A rotary percussion hydraulic drilling machine has striker piston slidably mounted inside a cylinder which defines a first annular chamber connected to a one-way valve slidably mounted inside a chamber connected to an accumulator comprising a diaphragm, leading to which is a hydraulic fluid inlet pipe and a second annular chamber connected to a control valve. This control valve, governed by the movements of the piston, connects the second chamber alternately to the high pressure pipe and to the return pipe. The valve, constructed in the form of a sleeve and subject to the force of a spring has a lateral connection allowing the direct passage of fluid to the return pipe, a rotary motor being located in the inlet pipe. Thus solely rotary operation for a rate of flow less than a certain threshold value and rotary/percussive operation for rates of flow beyond this threshold value may be obtained.

Abstract: The apparatus includes a rotatable hollow body (8) which comprises two sections (I and II). The first section (I) has a truncated pyramid or cone- frustrum type drum (9) rotatable around a longitudinal geometrical symmetry axis (x). Its side is formed, at least in part, by a sieve or filter (18). A feeder pipe (17) leads through a smaller end-plate (13) of the drum into the interior, while a larger end- plate (14) has an opening (15) eccentrically arranged in relation to the symmetry axis. The second section (II) of the hollow body in co-rotation with the first section joins this opening, and has at least three prismatic hollow-members (10, 11, 12) connected with each other. Their sides, at least in part, are formed by a sieve or filter (18). The geometrical longitudinal axes of the members together form a zig-zag line, intersecting the symmetry axis of the drum, which is also the common axis of rotation of the two sections of the hollow body, outside the drum. <IMAGE>

Abstract: A d.c. arc furnace, of the type in which powdered material is fed through a through- channel in the electrode(s), has a roof which, in addition to an insulating portion around the electrode(s), comprises a plane suspended portion defining the upper limit of an exhaust gas outlet, the lower limit of the outlet being defined by a threshold. The furnace is useful for melt redn. of oxides of e.g. iron, nickel, cobalt and chromium and materials contg. such oxides, by the methods of GB1455221 and 1467542. The design provides ample space at the side of the furnace vessel for the gas outlet thus reducing the gas flow rate and consequent rapid wear of the furnace lining, esp. at the outlet. The plane roof portion reverses the direction of upwards gas flow thus returning dust to the lower part of the furnace. Additionally, the roof is very easy to repair and can have a constant internal height close to the theoretical maximum height. Only a minor portion of the electrode(s) may extend into the furnace to reduce the risk of electrode rupture.

Abstract: The invention relates to a control circuit for controlling the driving and braking current of a brushless type DC motor of the type having a permanent magnet rotor and a pair of poles provided with two windings, the windings having a common junction which is connectable to the positive terminal of a DC voltage source. The windings are double wound on the core of the motor stator and a pair of controllable switching elements are in respective series with the windings. A scanning commutating circuit responsive to the angular position of the rotor has dual outputs for switching the switching elements on and off in a push-pull mode. Free wheeling diodes are connected respectively to the junctions of the windings and the switching elements and first and second current measuring resistors are in respective series relation to the switching elements and the diodes. A comparator circuit responsive to varying voltage drops effected by the current measuring resistors alternately blocks and unblocks the output of the scanning commutating circuit when the currents in the current measuring resistors reach predetermined values.

Abstract: A rivet locking arrangement (10) is equipped with a damping piston (16) which is influenced by the air pressure in a damping chamber (17) in the tool casing (11, 12), whereby the damping chamber (17) has such a volume that the casing (11) is isolated from undesired vibrations. A pre-stress spring (34) is aligned with the damping piston (16), between the head (30), on an axially mobile locking press or rod (31) and a rear core (28) of the piston. The spring (34) operates to reduce piston recoil during resistance stress via absorbing strike energy and converting a part of this to internal vibrations and heat. The core (28) is replaceable for the adjustment of the damping piston (16) for resistance work in conjunction with rivets of differing hardness.<IMAGE>

Abstract: The invention in question concerns a hook designed for a clothes hanger. This has an almost circular curved part (1) which surrounds approx. 3/4 of a circle and thereby, leaves a free opening for approx. 1/4 of the circle. The curved part (1) changes to a straight section (5) with a radial extension relative to the curved part (1).The innovation in the hook invention is that it includes another curved part (3) which completes an approx. 1/4 circle. This part is affixed to a movable sleeve (2) on the straight section (5). Via the working of a spring (4), the sleeve (2) is pressed into a joint where the sleeve's (2) furthest end from the spring (4) engages the transfer point between the first curved section (1) and the straight section (5). The second curved part (3) covers the free opening. The sleeve can be shoved manually, or via the operation of the spring (4), along the straight section so that the free opening is thereby released.<IMAGE>

Abstract: The invention relates to a drying apparatus for material in web form, especially a web of paper. The drying apparatus extends transversely across the paper web and has as its main component a support member reaching over the width of the web and rotatably mounted in two brackets, one on each side. With this support member is freely mounted a holder for heating or drying modules, so that these can be pivoted towards the moving web of material from a position remote from it. The elongate support member is a hollow body which acts as a cable channel for the supply cables leading to the individual dryer modules. The individual heating modules are arranged such that the cooling air first enters an air chamber like an air tank within the apparatus, in which the air pressure is evened out, in order to cool the quartz lamps which act as heating devices in the modules.

Abstract: This low friction rotatable electrical connector is for use with coiled telephone cords to prevent the cord from becoming twisted and knotted-up during use. This connector is generally of insulating material formed with a hollow housing having a first electrical female socket built into one end wall, and a circular opening in the opposite end wall for supporting a rotor assembly that is also of insulating material. The free end of the rotor assembly has a male phone plug. The innermost end of the rotor assembly has an enlarged head with a transverse face supporting a plurality of concentric electrical contact rings that are insulated from each other. A circuit board is clamped within the housing, and it has a first plurality of spring wire contacts that are each urged into continuous wiping contact with a separate one of the concentric rings. A second plurality of spring wire contacts are mounted to the circuit board within the female socket for making contact with a standard male phone plug. The housing is provided with partitions to provide spacers between the first plurality of spring wires and separate partitions for providing spacers between the second plurality of spring wires so as to retain these contact elements in place. The location of this rotatable connector relative to the coiled telephone cord has many possibilities. The connector can be at either end of the cord, or intermediate the length of the cord, or built into the handset.
