Abstract: To blank out noise pulses generated by activation and de-activation operations in a signal line to which direct current and alternating current can be applied simultaneously and which leads via an amplifier (V) to a loudspeaker (L), a circuit arrangement is proposed in which a relay (B) is provided which has contacts (b) inserted into the signal line. A switch (S) which initiates the switching of the relay contacts (b) and which has a delay component (R1, C1) connected downstream is disposed in the activation line of the relay (B). A pulse generator is connected to the output of the switch (S) which, when the switch (S) is opened and closed, transmits an adjustable-width square-wave pulse which is fed to a gate circuit (A, a) disposed between the amplifier (V) and the loudspeaker (L). The pulse generator has two parallel-connected branches leading to a monostable multivibrator, each branch containing a differentiator. In one of the branches, a memory circuit is connected upstream of the differentiator which transmits a voltage signal when the switch (S) is opened. Due to the circuit arrangement, the noise pulses in the signal line can be blanked out reliably even when activation and de-activation operations follow one another in rapid succession, for example in intercom systems. <IMAGE>

Abstract: A two-pole overcurrent protection device, intended for connection into a current-carrying conductor, comprises a normally conducting thyristor having members for firing the thyristor at low off-state voltage. The thyristor has a member for turning off the thyristor by short-circuiting one of its injecting junctions. Voltage-sensing members sense the on-state voltage drop across the thyristor and influence the short-circuiting member for turning off the thyristor when the on-state voltage drop reaches a pre-determined level. The overcurrent protection device may be constructed integrally with one single semiconductor plate.

Abstract: The present invention concerns a container 1 for keeping a bee swarm and for placing it in a beehive. The container is constructed of walls 3, 4 designed to enclose a space which can be shut, which is designed to accommodate the bee swarm, a closeable intake opening for the bee swarm and a closeable exit opening for the bee swarm. The exit opening can be common with the intake opening. The exit opening of the container is designed to be connected to a piece opening into the beehive, by which the container can communicate with the interior of the beehive. The container furthermore has a preferably relatively rigid piece 2, provided with a handle 12, which is intended to move in the direction of the exit opening and said open piece of the beehive and thereby successively reduce said space in the container so that the bee swarm moves over into the beehive. <IMAGE>

Abstract: The invention relates to a switch with manual or mechanical adjustment, which is suitable especially for transport systems in refrigerating and freezing rooms. In known switches, a conveyor band for driving the hooks serving for retaining the animal bodies often jumped off out of the path of the transport system. The object on which the invention is based is to provide a switch which can be overrun frictionlessly without any complications by the conveyor bands driving the hooks. The object is achieved, according to the invention, in that the end faces of the switch member are fastened at right angles to the respective end faces of the switch arms, in that the top side and underside of the switch member have different lengths, and in that the rotation of the switch member and the angles at the end faces of the switch member are critical for the lateral movement of the switch arm. <IMAGE>

Abstract: Improved apparatus for distributing a liquid in film form in the interior of vertical tubes in which a counterflow or cocurrent flow of liquid-vapor takes place. The apparatus includes a cylindrical body having an annular ledge and helical grooves on its peripheral surface, and wherein the cylindrical body is slightly tapered downwardly and inwardly to enable it to be easily introduced into the tube and to enable it to be freely rotated about its own vertical central axis. In the case of counterflow circulation, the cylindrical body has a blind laterally perforated vent tube on its top surface. In each instance the rotation of the body is effected by the liquid being distributed to inhibit the formation of deposits of solids from the liquid being distributed on the inner wall of the vertical tube.

Abstract: A method of increasing the temperature of shower water used in a wood grinding process wherein wood is ground in a grinding space (3) under a pressure exceeding atmospheric pressure, and warm shower water (G) is fed into the grinding space for improving the grinding process. In order to compensate losses of shower water replacement water (E) is added to the shower water circulating system. The replacement water is fed into the groundwood pulp (A) after the grinding space but before a steam separator. Thus cooler replacement water can be heated by the heat energy otherwise released from the groundwood pulp in the steam separator, and the temperature of the shower water can be maintained close to 100 DEG  C. in spite of the addition of cool replacement water and without using a pressurized steam separator.

Abstract: A process for producing hollow bodies from resin reinforced with woven and/or net fabrics, consists in securing edges D1 of a plurality of textile layers D to male die part B of a mould A-B which houses an expandable bladder or membrane C. Chamber C2 formed between die part B and membrane C is connectible to a pressurised fluid source so that, after securing the textile caps D to said male die part, and introducing the latter, together with the caps, into female die part A of the mould, pressurised fluid can be introduced into chamber C2, thereby imparting a controlled pressure to said caps. Either before or after the application of pressure resin is introduced into the mould to incorporate the textile reinforcement D under pressure, which is thus maintained in a state of constraint during and after curing. <IMAGE>
