Patent DE-3036611-A1 (DE)
Title: Sealed connection esp. between cable and duct - produced using hot-shrink thermoplastics tube which shrinks at one end and expands at the other
Inventor: MALTZ GEORG DIPL ING
IPC: B29C61/08
Filed: 1980-09-29
Abstract: Pressure tight, moisture tight connection between two components, one or both of which comprises a bore, is constructed using a hot-shrnk plastics sleeve. The sleeve (1) is first heated, and simultaneously expanded to a larger dia. at one end (A) and longitudinally stretched to reduce its dia. at the other end (B). The sleeve is then cooled. Its expanded end is then fitted over a pipe (2) or other component, while its reduced end (B) is fitted into a bore (3) of the second component. The sleeve is then heated, causing the wider end to hot-shrink onto the pipe (2) or the like, whle the narrower end shrnks longitudinally and expands radially to fit tightly into the bore (3). A claimed use is the connection of a cable or pipe (2) to a guide duct (3) in a casing or the like.

Title: Bed linen folding machine - includes suction plates and folding members between inner and outer pairs of conveyor belts
Inventor: COSI LUCIANO
IPC: B65H45/04
Filed: 1980-11-14
Abstract: The textile sheet folding machine for bed linen, towels etc. has a horizontal surface with two belt conveyors near the centre, between two wider outer belt conveyors. These are operated to advance a sheet, step it and return it. Between each inner and outer conveyor belt is a perforated strip connected to a suction source. Between each strip and its adjacent inner belt is a line of suction slots. The perforated strips are hinged parallel to the direction of travel of the sheets from end to end. Inside the structure carrying these members, are lifting members fitted with combs which swing at right angles to the direction of travel, acting in opposite directions, operated in sequence by a control system. A further stopping and positioning system controls the advance of the sheet.

Title: Hydraulic nut-tightening resetting device - has springs in cover bores pressing piston against cylinder shoulder keeping stretching bushing rotatable
IPC: B25B29/02
Filed: 1980-12-18
Abstract: The nut tightening device comprises a hydraulic pressure-operated piston (5) fitted inside cylinder (4). The cylinder has an upward extension (6) with ring shape provided with several axial bores in which springs (9) are fitted. Inside the ring (6) the bolt stretching bushing (7) is fitted with its lower tapped part screwed onto the protruding length of the bolt (2). The bolt stretching bushing has an axial central bore (7b) through which the initial position of the bushing (6) in relation to the end of the bolt (2) can be checked. After application of hydraulic pressure the length of stretching of the bolt can be measured through the same bore. The action of the springs keeping the piston away from the shoulder of the stretching bushing keeps the stretching bushing rotatable at all times.

Title: Electronic timing relay with a frequency-selective feedback oscillator
Inventor: FRIEDRICH KARL-DIETER ING GRAD
IPC: H03K3/03
Filed: 1981-01-30
Abstract: An electronic timing relay with a frequency-selective feedback oscillator is described which essentially consists of two series-connected gates, the inputs and outputs of which and the junction of which are combined with one another by means of a special circuit consisting of RC elements, in such a manner that a generator circuit is produced which, starting with commercially available CMOS components, meets the modern requirements for electronic timing relays. A frequency change at least at a ratio of 1 : 20 by means of low-resistance adjustable resistors ensures linear accuracy of the values to be input, with little circuit expenditure and very simple calibration without having to pay special attention to the tolerances of the components of the circuit.

Title: Transfer moulding press
Inventor: BIELFELDT FRIEDRICH BERND ING
IPC: B29C45/02
Filed: 1981-06-06
Abstract: The invention relates to a transfer moulding press for plastic compositions having a mould plate with a plurality of separate mould cavities and at least two cover plates, of which one is equipped with injection channels opening into the mould cavities. From a feed system, the material is forced into the mould cavities, comprising a cylinder cavity, runner plate and a displacement ram. Subsequently the feed system is moved out of the press, a sprue-removal plate is moved in and, after the press is closed, the mould plate is subjected to a heating effect via heating plates to vulcanise its contents. To prevent contamination of the passage bores by completely vulcanised material, the upper heating plate (4) is connected to the sprue-removal plate (5) and is thus arranged so as to be movable into and out of the press space. <IMAGE>

Title: Light barrier having an optotransmitter and an optoreceiver
Inventor: KAMMERER HEINZ ING GRAD
IPC: G01V8/12
Filed: 1981-08-08
Abstract: The invention relates to a light barrier, specifically a one-way light barrier, a reflection light barrier or a so-called forked coupler, in which locking devices are provided with the aid of which the optotransmitter can be arbitrarily blocked, and in which evaluation devices are provided by means of which in the event of blocking of the optotransmitter when there is no change in signal at the optoreceiver part which has previously been generating a received signal it is possible to generate an alarm signal so that it is finally possible to check the operational reliability of the light barrier. In this case, in an embodiment of the invention the use of at least two comparators also provides the possibility of signalling in good time an imminent failure of the light barrier, for example due to contamination of the transmitting optical system or of the receiving optical system.

Patent DE-3144799-A1 (DE)
Title: Percussion drilling rig
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B7/26
Filed: 1981-11-11
Abstract: A percussion drilling rig has been described which, striking and rotating autonomously in the borehole, draws its compressed air from a liquid-air bottle fitted in such a way that it can be quickly changed. A working pressure of about 500 bar already develops from the borehole heat under isochore heating in the bottle at 0 DEG C ambient temperature. Both the piston blow and the translation of the drill bit are effected pneumatically - the piston translation from percussion-mechanism exhaust air by its flows in an axially loaded coarse-pitch turbo-rotor at the nose of the hammer. A special feature of the type of construction is that an electric heating coil placed in the rig casing or on the outside of it can increase the pressure up to about 1500 bar by additional isochore heating of the liquid air in the bottle.

Title: Hot fluid conduit with admixing apparatus for cold fluid
Inventor: KLAS ERNST DIPL ING
IPC: B01F35/60
Filed: 1982-02-15
Abstract: A conduit for transporting a fluid at a high temperature T4, particularly in gas-cooled high temperature nuclear energy plants, consists of an inner conduit pipe (1) which is heat resistant but not pressure resistant, and an outer pipe (2) which is pressure resistant but which can only be loaded to a low temperature T1, the interspace between the two being packed with insulation (3). A fluid is fed into this conduit through an inlet duct (8) in amounts which vary with time; the temperature of the fluid can vary between two temperatures T2 and T3, which lie between the temperatures T1 and T4. The inlet duct (8), provided with an axial compensator (9) and connected via a cylindrical connection piece (10) to the pressure pipe, ends in an annular header (5) from which lead a number of infeed ducts, uniformly distributed over the periphery; these project into the interior of the conduit pipe (1) and thereby cause a turbulent action, if necessary supported by obliquely set guide plates (7), such that the two fluids are already intimately mixed after a short path. The annular header (5) is arranged in the region of the insulation (3) where likewise a temperature region T2-T3 is naturally set, so that it is subjected to no particular heat loads irrespective of whether or not fluid is fed in through it. <IMAGE>
