Patent DE-3208555-A1 (DE)
Title: Spreader
Inventor: VOELS GERD
IPC: A01C15/04
Filed: 1982-03-10
Abstract: Spreader. This serves in horticulture, but also for the spreading of salts, for the thawing of frozen footpaths, etc. The material to be spread passes from the container to the outer edge of the bucket wheel or impeller provided, where an air channel is arranged outside the impeller in such a way that the outside air is sucked in by the impeller and this turbulence causes the spreading material falling from the container into the mouthpiece provided to be thrown out of the mouthpiece in an unimpeded manner. To keep the outflowing quantity of material to be spread variable, there is attached to the throughflow orifice of the container an adjustable slide which can be regulated to different throughflow quantities by means of a hand lever.

Title: Circuit arrangement for centrally controlled telecommunications systems, in particular telephone PBX systems, with central and local devices controllable via data transmission trunk groups (central program sub-memory devices)
Inventor: PAULMICHL ERICH DIPL ING
IPC: H04Q3/545
Filed: 1982-03-30
Abstract: Within the telecommunications system, one or more local devices (ED1, m) are provided which in each case have dedicated central sub-control devices (CPU1, m) to which program sub-memory devices (PMU1, m) are permanently allocated, which sub-memory devices are connected, via the data transmission trunk group (IEC) collectively allocated to all peripheral devices (ED1, m), to the higher-order central control device (CP). To relieve the data transmission trunk group (IEC), the internal control procedures of the peripheral devices (ED1, m) are controlled separately by the central sub-control devices (CPU1, m) in conjunction with the allocated program sub-memory devices (PMU1, m). Circuit arrangements of this type are used for telecommunications systems, in particular for telephone PBX systems. <IMAGE>

Patent DE-3243010-A1 (DE)
Title: Device for portioning and compressing foodstuffs
Inventor: REIFENHAEUSER TONI
IPC: B26D7/06
Filed: 1982-11-20
Abstract: The device essentially comprises a filling shaft (2) and a chamber (3) which are separated from each other by a cutting element (1). In each case one side wall of the filling shaft (2) and of the chamber (3) takes the form of a flap (4) or a pressure ram (13) or else by a panel element (20) and a pressure ram (21), which allows that the volume of the filling shaft (2) and the chamber (3) to be changed. The filling shaft (2) and the chamber (3) can receive an adjustable maximum volume during the filling process, and then the chamber (3) is closed by means of the cutting element (1), after which the walls of the filling shaft (2) and the chamber (3) are moved into a position which brings about an appropriate reduction in the volume of the filling shaft (2) and the chamber (3). <IMAGE>
Patent DE-3246132-A1 (DE)
Title: Rapid testing of solutions involving concentration indication by zone length
Inventor: VLCEK BOHUSLAV DR
IPC: G01N31/22
Filed: 1982-12-14
Abstract: The test strips used in chemical and medical practice for rapid analysis are based on a colorimetric principle, and their objective evaluation requires a special colorimeter. The finished products described here are based on the reversed titrimetric principle: glass tubes (or paper strips) contain, on a hydrophilic carrier, a sparingly soluble titrant which undergoes a colour change on reaction. On immersion, the rising solution uses up some of the titrant, resulting in a differently coloured zone whose sharp boundary directly indicates the concentration of the required substance. Reading off can be carried out immediately after the impregnation, which requires a few minutes; even during the subsequent hour. Because no chemical equipment is required, the method is suitable, in particular, for terrain analyses. The basic formulae are derived for the method and the designation "titrigraphy" is proposed. Examples which are described are tubes for determining: a) chlorides (in water or urine), containing silver chromate on a silica gel/polyamide carrier, b) iron(II), containing tris(laurylammonium) ferricyanide on polyamide, and c) zinc or cadmium, containing molybdenyl ferrocyanide on cellulose.
Patent DE-3305242-A1 (DE)
Inventor: MAIER RUDOLF
IPC: B29C48/475
Filed: 1983-02-16
Abstract: A nozzle assembly for extruding a tube has an outer housing sleeve having an inner surface centered on an axis and having an axially forwardly directed front end and a core formed of attached-together front, intermediate, and rear core ports. The front core part lies within the sleeve at the front end thereof and forms with the inner housing surface an annular axially forwardly open extrusion passage. The intermediate core part lies within the sleeve axially behind the front core part and is formed with a pair of grooves opening radially outward into the passage and each defined by a respective annular rear face extending generally perpendicular to the axis, a respective annular front face confronting the rear face and extending generally perpendicular to the axis, and a heart-shaped annular surface axially bridging the respective faces, facing radially forward, and having a portion forming a radially forwardly directed point. The rear core part lies within the sleeve axially behind the intermediate core part and axially rearwardly closes the passage. At least one feed passage in the rear and intermediate core parts serves for feeding a mass to be extruded under pressure to the grooves at locations therein generally diametrally opposite the respective points. Each of the grooves has its region of greatest radial depth at the respective location and the feed passage opens radially into the grooves.

Title: Relief valve in a hydraulic system
Inventor: GROB ALFRED
IPC: F15B13/02
Filed: 1983-03-02
Abstract: The relief valve for a pump (13) has a pressure-limiting valve (28) which is provided with an extension (32). This passes through a piston (33) which, in the event of a relatively long relieving operation, lifts the valve member (25) of the pressure-limiting valve well clear of the valve seat (24) by acting on the extension (32), with the result that the pressure level is determined by a pressure-holding valve (46) which is positioned downstream of the pressure-limiting valve (28) and is set to a low pressure. <IMAGE>

Title: Contact-free two-quadrant converter having a device for triggering on demand
Inventor: SCHAER ROLAND
IPC: H02M7/515
Filed: 1984-04-14
Abstract: Contact-free two-quadrant converter circuits upstream of a phase-sequence invertor on the DC network require that the freewheeling thyristor (TA) and the braking thyristor (TB) be triggered on demand. In the case of this triggering on demand, either the freewheeling thyristor (TA) (a mode) or the braking thyristor (TB) (b mode, changeover from driving to braking grouping) is triggered in each case at the voltage zero crossover on the freewheeling thyristor (TA). The invention offers a simple, reliable and cheap solution, in that the voltage zero crossover on the freewheeling thyristor (TA) is detected using a pulse transformer (IT) and is passed to the control unit (L). The corresponding triggering pulses are then formed in the control unit. <IMAGE>
