Title: Universal pipe with partition-wall pipe
Inventor: PUSCH SIEGFRIED
IPC: F16L53/70
Filed: 1988-05-04
Abstract: The universal pipe with partition-wall pipe solves problems of various types, cooling or heating can be carried out therewith. The construction of the universal pipe can be produced simply and cost-effectively. The choice of material corresponds to the usage. There are possible applications for the universal pipe in virtually every sector. The universal pipe itself can be produced in any size and length. The function of the universal pipe: the coolant or heating medium flows through the inlet connection stub into the chamber I, from there it flows, by virtue of forced circulation, through the partition-wall pipe as far as the annular front plate and then into the chamber II, from the chamber II into the collector piping cover chamber, from there via the outlet connection stub, to the control valve, by means of which the temperature of the coolant or heating medium is controlled. The universal pipe should always be under pressure during operation. <IMAGE>

Title: Electrically driven hand tool
Inventor: KASTREUZ GERHARD DR
IPC: H01R4/72
Filed: 1988-06-18
Abstract: The electrically driven hand tool having a housing (1) and having a mains cable (5) which opens into the housing (1) has a cable sheath (6) which surrounds the mains cable (5) in the region of the opening into the housing (1). The cable sheath (6) is shrunk onto the mains cable (5). As a result of the cable sheath (6) being shrunk onto the mains cable (5), the strength of said mains cable (5) is considerably increased and wires within the mains cable (5) are largely prevented from breaking. The shrunk joint between the cable sheath (6) and the mains cable (5) can also be used as a strain-relief device for the mains cable (5). <IMAGE>

Title: Seed-depositing synchronising device for high-speed agricultural seed drills
Inventor: OBERSCHMID RAIMUND DR RER NAT
IPC: A01C7/04
Filed: 1988-08-03
Abstract: In a method for sowing individual grains, there is installed in the seed-guide channel (3) between the seed dispenser (1) and seed-depositing point (2) a synchronising device (4) which accelerates or decelerates the grains as a periodic function of the frequency of the seed supply and of a specific phase relationship, so that time deviations at the seed dispenser (1) and on the way to the synchronising device (4) in relation to the desired passage time of the grain in the remaining grain-guide channel (3b) are largely compensated. There is no need for an intermediate storage or a position of rest of the grains on the way between the seed dispenser and depositing point. The depositing accuracy of the grains, particularly at high sowing speeds (e.g. 15 km/h), is consequently improved considerably. <IMAGE>

Title: Dough-cutting machine with cutting chambers and discharging piston
Inventor: RICHTER CONRAD DIPL ING
IPC: A21C5/04
Filed: 1988-08-09
Abstract: Dough-cutting machines of this type are to be able to insert the compressible dough into the measuring chambers more gently than hitherto, while retaining their metering accuracy, exerting a much smaller pressure and increasing the duration of loading by about 50% of exemplary operation in order to prevent irreversible damage to the dough, despite increasing throughput. The dough-cutting machine therefore has a pressure chamber (4) which is arranged between the slide (6) and a continuously rotating metering drum (9) and is directly connected to a spring-loaded pressure compensation chamber (5), the head-side covering wall of which is bounded in a vertically elastic fashion, preferably by a flat-topped piston. The dough-cutting machine designed in such a manner can be used, in a way which is productive and ensures that standards of quality are maintained, especially for the volumetric feeding of small cakes and pastries made of wheat. <IMAGE>
Patent DE-3831176-A1 (DE)
Title: Oscillator cell
Inventor: RONECKER ANDREAS DIPL ING
IPC: H03L5/00
Filed: 1988-09-13
Abstract: The oscillator cell (OZ) contains an oscillator (OS) consisting of an amplifier (VST) and a frequency-determining system (FS), for example a crystal. To be able to operate the oscillator cell (OZ) reliably independently of parameter fluctuations and without calibration, the slope of the amplifier (VST) is set with the aid of a control loop. In addition to the amplifier (VST), the control loop contains an amplitude discriminator (AD) and a feedback network (RK). The feedback network (RK) generates a control voltage (US) for setting the slope of the amplifier (VST). During the settling process, the feedback network (RK) first generates a low control voltage (US) which leads to a shallow slope of the amplifier. The control voltage is then slowly increased. Correspondingly, the slope of the amplifier is steepened. This is done until the oscillator (OS) reliably oscillates. The oscillator voltage (UA) output by the amplifier has then become so large that it exceeds the threshold voltage of the amplitude discriminator. This outputs a signal (UD) for the feedback network (RK) which causes the latter to lower the control voltage (US) and to set it to the operating value. The consequence is that, in operation, the amplifier (VST) operates with a shallow slope so that the power dissipation of the oscillator is minimal. A Pierce oscillator can be used as oscillator (OS). <IMAGE>
Patent DE-3836440-A1 (DE)
Title: Process for the underground production of lines embedded in the soil in a constraint-free manner
Inventor: STEIN DIETRICH PROF DR ING
IPC: E03F3/06
Filed: 1988-10-26
Abstract: For the underground production of lines embedded in the soil in a constraint-free manner, provision is made for producing a durable and defined annular gap directly behind the advancement machine, between the casing surface of the advanced run of pipes and in-situ soil, which annular gap, immediately during advancement, is filled with a long-term-resistant, low-viscosity or thixotropic material which prevents loading of the pipelines by movements of the soil. The foundation-side delimitation and sealing of the annular gap takes place by a water-impermeable plastic sheath which, simultaneously with the advancement elements, is pushed in, drawn in or produced in situ.

Title: Coin insertion and return arrangement for deposit coins
Inventor: FUCHS PETER
IPC: G07F7/06
Filed: 1989-01-11
Abstract: Trolleys available in supermarkets for goods transport or on stations for suitcases are usually left standing at the unloading point by the customers or travellers and no longer returned to the collecting station. The continual recovery of these trolleys necessitates additional labour. Such trolleys are therefore often lined up interlocked with one another at the collecting station and released only in return for the insertion of a deposit coin. A disadvantage of this is that customers or travellers cannot do their shopping or transport their luggage if they do not have a suitable coin to hand. So that trolleys can initially be used even without a deposit coin and, nevertheless, in order to guarantee their return by the customers or travellers, there are provided on the trolleys coin insertion and return arrangements for deposit coins which have a releasable holding device 4 for the deposit coin 3 in a coin chamber 2. This holding device 4 is an electromagnet 15 which is provided with a longitudinally displaceable armature 17 and the excitation of which takes place by means of an electrical switching member 23 in the form of an infrared receiver device by an external infrared transmitter 25 which is arranged at the collecting station. The deposit coin 3 subsequently inserted at a later time is returned only when the trolley enters the local transmission range. The coin insertion and return arrangement is particularly suitable for shopping trolleys and for suitcase carts... Original abstract incomplete. <IMAGE>

Title: Window-cleaning system
Inventor: BAUMGARTEN PETER
IPC: B60S1/52
Filed: 1989-03-11
Abstract: A description is given of a window-cleaning system having a spraying device, in which a nozzle element made of an elastic material is arranged within an adjustable nozzle body of ball-like design. The spraying aperture is normally closed by the nozzle element made of an elastic material. The spraying aperture is opened only by the pressure of the washer fluid. With a design of this kind, the direction of the spraying jet can be set precisely, but because of the closable nozzle opening the washer fluid is prevented to a very large extent from freezing up.
