Patent DE-3013228-A1 (DE)
Title: Headphone earpiece for long duty hours - has transducer moulded in multi-material casing with recess for ear
Inventor: WARISLOHNER JOSEF
IPC: H04M1/05
Filed: 1980-04-03
Abstract: An earpiece containing an electro-acoustic transducer (5) embedded in a soft, moulded layer (4) of rubber or plastic material surrounding a hard core portion (8) is supported by moulded-in brackets (42a,26). The brackets of the left and right ear pieces are interconnected by adjustable straps laid over head and chin when mounted. The earpiece does not press against the ear itself, rather it freely protrudes into a recessed space (2) with its rear part. The pressure is taken by the head around the ear in that very soft portions (3,4) bear against the head. The special resilience of these portions is obtained by enclosures (11) of expanded rubber or other material containing many air bubbles. The recessed space (2) is open at the top to allow environmental noise to reach the ear which is important in service situations. The supply of power as well as the electrical connection of a throat microphone may be by means of a plug whose sharp-pointed contact pins pierce a layer of sponge rubber or the like before reaching the mating socket pins thereby protecting the latter from corrosion in outdoor conditions.

A second crank controls the pivoting movement of the door in relation to the first one. This mechanism is driven by a motor. There is a slip clutch between this motor and the mechanism, while a second motor and mechanism on the door frame, or the door proper, thrusts the door, once moved into the frame, into the locked position, and works with a stop. The second motor is switched on by a limit switch, as the door moves into the frame, and off by a second limit switch actuated by its thruster mechanism.
Patent DE-3033723-A1 (DE)
Title: Hydraulically operable crimping tool for electrical connector - has hydraulic pump unit to move pin towards connector, with oil movement controlled by check valve
Inventor: SVENSSON UNO
IPC: H01R43/042
Filed: 1980-09-08
Abstract: The hydraulically operable crimping tool (1), is primarily for attaching an electrical connector to an electrical conductor, and consists of a hydraulic oil reservoir (27), which is in fluid communication with a pump unit (26) which when operated will pump oil under pressure into smaller and larger enclosed spaces (24) and (25) respectively. A pin is arranged so as to move towards the electrical connector as pressure is applied. Upon the initial actuation of the pump unit (26) oil is pumped into the small space (24) of small area and volume, whereby a small quantity of oil produces large movement of the pin (1k) towards the electrical connector. This movement then causes the large space (25) of greater area and of greater volume than the small space (24) to be filled with oil. As resistance to the movement of the pin (1k) begins to occur due to contact of the pin with the electrical connector, the pump unit (26) pumps oil to the large space (25) to effect the crimping action.

Patent DE-3100271-A1 (DE)
Title: Method and apparatus for cutting up pieces of metal into narrower sections
Inventor: SUZUKI YASUO
IPC: B23D19/06
Filed: 1981-01-08
Abstract: A pair of driven cutter rolls arranged one above the other and having annular wedge elements is used to cut a relatively hot piece of metal of rectangular cross-section into three or more narrower sections. The annular wedge elements dig into the piece of metal, which is transported in its longitudinal direction, and form V-shaped grooves in it. The angle between the flank which is closer to the cast side of the piece of metal to be cut up and on which the cutting force acts and a perpendicular to the rolling axis is larger than the angle between the other flank and the same perpendicular. The cross-section of the annular wedge element is thus asymmetric relative to the plane passing through the vertex of the wedge element and extending perpendicular to the rolling axis. <IMAGE>

Title: Process for modifying the surface properties of disc-shaped mouldings of vinyl chloride-based synthetic engineering resins
Inventor: IMADA KIYOSHI
IPC: B29D17/00
Filed: 1981-02-06
Abstract: In the case of the process for modifying the surface properties, in particular improving the antistatic behaviour and abrasion resistance, of flat, in particular disc-shaped, PVC mouldings, in particular phonographic records, the surface to be modified of the PVC moulding is subjected to the action of a cold plasma. In order to ensure the greatest possible homogeneity of the distribution of the effects induced by the plasma action, the mouldings with the surfaces to be treated are passed during the action of the cold plasma in a translatory movement through an intermediate space which is formed between two groups of electrodes arranged opposite and parallel to each other. This translation of the moulding is preferably additionally superimposed by a rotation about its own axis, that is to say a rotation in its principal plane. The individual electrodes of the two mutually opposite groups of electrodes for generating the cold plasma are either connected in such a way that all the electrodes of one of the two groups are connected to phase and all the electrodes of the other group are connected to earth, or are connected in such a way that the electrodes of a particular group are respectively connected alternately to phase and to earth, the mutually assigned opposing individual electrodes of each of the two groups being poled in such a way that an electrode of one polarity in one of the two groups is always opposed by an assigned counterelectrode in the other of the two groups, which has the respectively opposed polarity of the electrode assigned to it. To stabilise and intensify the effects which can be achieved in the cold plasma, the phonographic records treated under these conditions in the cold plasma are coated with a surface-active agent after being exposed to the action of the plasma.

Title: Telephone station with a microphone amplifier
Inventor: GOERLITZ HANS DIPL ING
IPC: H04M1/60
Filed: 1981-03-24
Abstract: The invention relates to a circuit arrangement for line-powered telephone stations with an operational amplifier (I in Fig. 1 and 2) as a microphone amplifier, the operational amplifier (I) being decoupled by means of capacitors from the rest of the circuit (C1 to C4 in Fig. 1) and these capacitors, in the charged condition, characterising, for example, the DC voltage condition of the amplifier. The intended object of the invention is to define a station circuit of this type in such a way that minimal power is required during the capacitor charging period. The object is solved in that a voltage divider (R6, R7/R8, R9 in Fig. 2) provided for each amplifier input (+, -) comprises two equal-size resistors (R6, R7 or R8, R9) and that an equal-size capacitor is connected in parallel with each of these resistors (R6, C5/R7, C6/R8, C7/R9, C8, 25 in Fig. 2), two of these capacitors (C5, C6 in Fig. 2) decoupling the microphone (M). This produces the advantage that all the capacitors charge up more or less evenly and therefore hardly any voltage difference occurs between the two amplifier inputs, and the amplifier draws no power from the subscriber line for a load current. The invention can essentially be used in all line-powered telephone stations with a microphone amplifier. <IMAGE>

Abstract: The invention relates to haemodialysis and haemofiltration therapy and is predominantly intended for the treatment of chronic kidney failure. It is the aim of the invention to permit free alternation between the treatment methods of haemodialysis, haemofiltration and sequential ultrafiltration and hence, in particular, to provide an optimum individual therapeutic regimen. The object of the invention is a uniform technical system for all the abovementioned treatment methods, with determination of the effectiveness of treatment and control of the treatment procedure being based on a uniform continuous ultrafiltration measurement. The device according to the invention has, inter alia, two pumps under coupled control with different delivery streams which are in an exact dosage ratio to one another. The excess occurring in the system is discharged toward the outside and recorded by a flowmeter whose the output signal is used to control a pressure-influencing element via a central control unit for regulation of the ultrafiltration rate. A change-over to pure ultrafiltration is possible by the central control unit and separately controllable valves. <IMAGE>

IPC: C04B40/02
Filed: 1981-10-01
Abstract: The invention relates, on the one hand, to a process and, on the other hand, to a device for the rapid setting of concrete and similar cast materials by carbonisation. The process is characterised by effective drying-out of the capillary system of the material in the setting device before and/or during the carbonisation, by controlled states in the form of an airstream, heat generation and moisture absorption in a continuous circulation process. The device for applying the abovementioned process is characterised by a hermetically sealed unit which contains equipment for air circulation and heat generation and a control device for conditioning, which are connected to the sealed unit. These equipment units can be active together or individually, namely as a function of the composition, structure, geometry, etc., of the materials which are to set. In the same way, in conjunction with the device, vacuum suction can be connected to the setting device, whenever a vacuum treatment is possible, i.e. in the case of a closed mould or closed chamber. Complete dehumidification of the casting material can be effected by air circulation, heat supply and dehumidification with the casting material in a completely closed system. <IMAGE>
