Patent DE-4305308-A1 (DE)
Title: Piston pump
IPC: F04B53/10
Filed: 1993-02-20
Abstract: The invention relates to a piston pump for delivering media, especially UV-curing printing inks or coating compositions, which has a pump body with a pump chamber. On the inlet side, an inlet line (suction line) is connected via an intake valve (suction valve). The pump chamber accommodates a reciprocating piston which, via a piston rod, is in effective connection with a drive. The piston itself is provided with a discharge valve which is closed during the suction movement of the piston and is opened during the discharge movement of the piston. As a result, the piston delivers the flow medium into a discharge chamber which adjoins the pump chamber on the outlet side and to which an outlet duct is connected. To avoid premature polymerisation of the medium to be delivered, the piston can be moved back and forth in the pumping chamber, without sealing rings or the like, with little play and essentially in a non-contact manner.

Title: Hollow body for electrical installation, and for use in concrete ceilings
Inventor: DEBIE PETER DIPL ING
IPC: E04B9/00
Filed: 1993-06-30
Abstract: The invention relates to a hollow body for electrical installation and for use in concrete ceilings. These concrete ceilings have been produced using the so-called double-concreting method. They consist of a prefabricated ceiling part in the form of a panel and having a facing concrete lower layer, and of a concrete layer which is cast in situ and can be applied over it. A hollow body 18, which consists of a rear part 19 and of a front part 20, is arranged in an aperture which can be produced in the prefabricated ceiling part. These two parts are joined together by means of connecting elements 25 and 31 to form a structural unit. The front part 20 is inserted into the aperture which is produced in the prefabricated ceiling part. Relative movement takes place between the front part 20 and the rear part 20 in such a manner that the connecting stub 29 of the front part 20 projects beyond the lower side of the prefabricated ceiling part. A shell cover is then connected in a rotationally fixed manner to the front part. The shell cover and the front part are then twisted together. The structural unit is in this way braced on the prefabricated ceiling part. At least one connecting housing 21 can also be connected, if required, to the structural unit, which consists of the rear part 19 and the front part 20, of the hollow body 18. This is done simply by plugging it on. <IMAGE>
Patent DE-4323263-A1 (DE)
Title: Stock inlet for paper-making machine - has flow-controlled jet feeds across main flow channel section with main flows and turbulence zone, allowing cross=sectional adjustment, etc.
Inventor: BEGEMANN ULRICH
IPC: D21F1/02
Filed: 1993-07-12
Abstract: Inlet has at least one channel section of the machine width with a main flow and a turbulence zone. Feeds, each with a flow control, are distributed to open across the machine width, with an inflow angle between the feeds and the main flow line to maintain a constant flow vol. downstream of the feeds, immediately after them, independently of the vol. through the feeds. Also claimed is a method used to affect the suspension flow at the stock inlet with a feed angle for the feeds against the main flow line as separate jets to give a sectional effect. The feed angle is selected to give no change in the total vol. flow directly after the feed. The sectional change to the paper weight is affected by the concn. of the injected feed and its vol.. An initial channel, of machine width, is divided by at least one sepg. wall along the flow line. The feed angle deviates by 5-85 deg. from the normal main flow. Each feed has a vol. flow control. At least two rows of jet feeds are deployed in succession, with a different feed angle between the jet rows, where the feed angle of the upstream row is larger than in the next row, or vice versa. With three rows of feed jets, the upstream angle is larger than the centre angle, where there is no change in the total vol. flow at the zone, and a further angle is smaller. The feed angles are varaible, and the feed channels open into the machine-width channel, at the end side at the outlet of the stock inlet. The turbulence is formed by a number of channels or tubes, into which the feeds open at least partially. The feed angles are varied to increase or decrease the vol. by sections, together with variations in fed suspension concns. and vols.. The paper wt. to be produced can be adjusted by setting the feed angle to the main flow with feed points displaced from the main flow. The concn. is adjusted at least at one feed, and at least partially directly into the turbulence channels or tubes. This also sets the fibre orientation and the paper wt.. At least one feed is supplied by two channels with a suspension of different densities and vol.. USE/ADVANTAGE - The stock inlet for a papermaking machine is opeated efficiently and without pressure loss, with adjustments to change the paper wt. and the fibre orientation without altering other parameters.

Patent DE-4338288-A1 (DE)
Inventor: KOCHS KARL-JOSEF
IPC: A41H37/02
Filed: 1993-11-10
Abstract: In a pressure-operated press, two plungers which are nested one inside the other are used in a cylinder housing. The one plunger serves as a beading plunger to fix an eyelet in a punched-out hole in a web. Located in this beading plunger is an internal cylinder in which the second inner plunger is arranged. The latter serves as a cutting plunger to punch the hole in the web before the eyelet is set. In order to carry out the hole-punching and eyelet-setting in a particularly efficient manner, it is proposed to provide the beading plunger with a plunger head which is sealed off in the cylinder housing and by means of which the pressure space in the cylinder housing is divided into two separate part space. The front space thus produced in the front region of the plunger head is provided with a first pressure-medium line while a second independent pressure-medium line ends in a rod space located below the plunger head. Only this second pressure-medium line is connected to the internal cylinder in the beading plunger. The cutting plunger can be provided with a head region which is guided so as to be sealed off in the internal cylinder in the beading plunger. This allows control of the pressure medium, said control being connected in both pressure-medium lines and actively causing the working stroke as well as the return stroke of the beading plunger. The pressure relief valve can only be switched into the second pressure-medium line connected to the internal cylinder and only for a limited time during the working stroke. This has a pressure-increasing effect only on the cutting plunger.
